Order of legend entries in ggplot2 barplots with coord_flip()
|
<p>I'm struggling get the right ordering of variables in a graph I made with ggplot2 in R.</p>
<p>Suppose I have a dataframe such as:</p>
<pre><code>set.seed(1234)
my_df<- data.frame(matrix(0,8,4))
names(my_df) <- c("year", "variable", "value", "vartype")
my_df$year <- rep(2006:2007)
my_df$variable <- c(rep("VX",2),rep("VB",2),rep("VZ",2),rep("VD",2))
my_df$value <- runif(8, 5,10)
my_df$vartype<- c(rep("TA",4), rep("TB",4))
</code></pre>
<p>which yields the following table:</p>
<pre><code> year variable value vartype
1 2006 VX 5.568517 TA
2 2007 VX 8.111497 TA
3 2006 VB 8.046374 TA
4 2007 VB 8.116897 TA
5 2006 VZ 9.304577 TB
6 2007 VZ 8.201553 TB
7 2006 VD 5.047479 TB
8 2007 VD 6.162753 TB
</code></pre>
<p>There are four variables (VX, VB, VZ and VD), belonging to two groups of variable types, (TA and TB).</p>
<p>I would like to plot the values as horizontal bars on the y axis, <strong>ordered vertically first by variable groups and then by variable names</strong>, faceted by year, with values on the x axis and fill colour corresponding to variable group.
(i.e. in this simplified example, the order should be, top to bottom, VB, VX, VD, VZ)</p>
<p>1) My first attempt has been to try the following: </p>
<pre><code>ggplot(my_df,
aes(x=variable, y=value, fill=vartype, order=vartype)) +
# adding or removing the aesthetic "order=vartype" doesn't change anything
geom_bar() +
facet_grid(. ~ year) +
coord_flip()
</code></pre>
<p>However, the variables are listed in reverse alphabetical order, but not by <strong>vartype</strong> : the <code>order=vartype</code> aesthetic is ignored. </p>
<p><img src="https://i.stack.imgur.com/GGZNG.png" alt="enter image description here"></p>
<p>2) Following an answer to a similar question I posted yesterday, i tried the following, based on the post <a href="https://stackoverflow.com/questions/5208679/order-bars-in-ggplot2-bar-graph">Order Bars in ggplot2 bar graph</a> :</p>
<pre><code>my_df$variable <- factor(
my_df$variable,
levels=rev(sort(unique(my_df$variable))),
ordered=TRUE
)
</code></pre>
<p>This approach does gets the variables in vertical alphabetical order in the plot, but ignores the fact that the variables should be ordered <strong>first by variable goups</strong> (with TA-variables on top and TB-variables below).</p>
<p><img src="https://i.stack.imgur.com/z7hYe.png" alt="enter image description here"></p>
<p>3) The following gives the same as 2 (above):</p>
<pre><code>my_df$vartype <- factor(
my_df$vartype,
levels=sort(unique(my_df$vartype)),
ordered=TRUE
)
</code></pre>
<p>... which has the same issues as the first approach (variables listed in reverse alphabetical order, groups ignored)</p>
<p>4) another approach, based on the original answer to <a href="https://stackoverflow.com/questions/5208679/order-bars-in-ggplot2-bar-graph">Order Bars in ggplot2 bar graph</a> , also gives the same plat as 2, above</p>
<pre><code>my_df <- within(my_df,
vartype <- factor(vartype,
levels=names(sort(table(vartype),
decreasing=TRUE)))
)
</code></pre>
<p>I'm puzzled by the fact that, despite several approaches, the aesthetic <code>order=vartype</code> is ignored. Still, it seems to work in an unrelated problem: <a href="http://learnr.wordpress.com/2010/03/23/ggplot2-changing-the-default-order-of-legend-labels-and-stacking-of-data/" rel="noreferrer">http://learnr.wordpress.com/2010/03/23/ggplot2-changing-the-default-order-of-legend-labels-and-stacking-of-data/</a></p>
<p>I hope that the problem is clear and welcome any suggestions.</p>

<p><em>I posted a similar question yesterday, but, unfortunately I made several mistakes when descrbing the problem and providing a reproducible example.
I've listened to several suggestions since, and <strong>thoroughly searched stakoverflow for similar question and applied, to the best of my knowledge, every suggested combination of solutions, to no avail.</strong>

Piping for input/output
|
<p>This question follows from my attempt to implement the instructions in:</p>
<p><a href="https://stackoverflow.com/questions/1734932/linux-pipes-as-input-and-output">Linux Pipes as Input and Output</a></p>
<p><a href="https://stackoverflow.com/questions/2784500/how-to-send-a-simple-string-between-two-programs-using-pipes">How to send a simple string between two programs using pipes?</a></p>
<p><a href="http://tldp.org/LDP/lpg/node11.html" rel="nofollow noreferrer">http://tldp.org/LDP/lpg/node11.html</a></p>
<p>My question is along the lines of the question in: <a href="https://stackoverflow.com/questions/1734932/linux-pipes-as-input-and-output">Linux Pipes as Input and Output</a>, but more specific.</p>
<p>Essentially, I am trying to replace:</p>
<pre><code>/directory/program < input.txt > output.txt
</code></pre>
<p>using pipes in C++ in order to avoid using the hard drive. Here's my code:</p>
<pre><code>//LET THE PLUMBING BEGIN
int fd_p2c[2], fd_pFc[2], bytes_read;
// "p2c" = pipe_to_child, "pFc" = pipe_from_child (see above link)
pid_t childpid;
char readbuffer[80];
string program_name;// <---- includes program name + full path
string gulp_command;// <---- includes my line-by-line stdin for program execution
string receive_output = "";
pipe(fd_p2c);//create pipe-to-child
pipe(fd_pFc);//create pipe-from-child
childpid = fork();//create fork
if (childpid < 0)
{
cout << "Fork failed" << endl;
exit(-1);
}
else if (childpid == 0)
{
dup2(0,fd_p2c[0]);//close stdout & make read end of p2c into stdout
close(fd_p2c[0]);//close read end of p2c
close(fd_p2c[1]);//close write end of p2c
dup2(1,fd_pFc[1]);//close stdin & make read end of pFc into stdin
close(fd_pFc[1]);//close write end of pFc
close(fd_pFc[0]);//close read end of pFc
//Execute the required program
execl(program_name.c_str(),program_name.c_str(),(char *) 0);
exit(0);
}
else
{
close(fd_p2c[0]);//close read end of p2c
close(fd_pFc[1]);//close write end of pFc
//"Loop" - send all data to child on write end of p2c
write(fd_p2c[1], gulp_command.c_str(), (strlen(gulp_command.c_str())));
close(fd_p2c[1]);//close write end of p2c
//Loop - receive all data to child on read end of pFc
while (1)
{
bytes_read = read(fd_pFc[0], readbuffer, sizeof(readbuffer));
if (bytes_read <= 0)//if nothing read from buffer...
break;//...break loop
receive_output += readbuffer;//append data to string
}
close(fd_pFc[0]);//close read end of pFc
}
</code></pre>
<p>I am absolutely sure that the above strings are initialized properly. However, two things happen that don't make sense to me:</p>
<p>(1) The program I am executing reports that the "input file is empty." Since I am not calling the program with "<" it should not be expecting an input file. Instead, it should be expecting keyboard input. Furthermore, it should be reading the text contained in "gulp_command."</p>
<p>(2) The program's report (provided via standard output) appears in the terminal. This is odd because the purpose of this piping is to transfer stdout to my string "receive_output." But since it is appearing on screen, that indicates to me that the information is not being passed correctly through the pipe to the variable. If I implement the following at the end of the if statement,</p>
<pre><code>cout << receive_output << endl;
</code></pre>
<p>I get nothing, as though the string is empty. I appreciate any help you can give me!</p>
<p>EDIT: Clarification</p>
<p>My program currently communicates with another program using text files. My program writes a text file (e.g. input.txt), which is read by the external program. That program then produces output.txt, which is read by my program. So it's something like this:</p>
<pre><code>my code -> input.txt -> program -> output.txt -> my code
</code></pre>
<p>Therefore, my code currently uses,</p>
<pre><code>system("program < input.txt > output.txt");
</code></pre>
<p>I want to replace this process using pipes. I want to pass my input as standard input to the program, and have my code read the standard output from that program into a string.</p>

How do I rewrite my MySQL update statement to eliminate "Truncated incorrect INTEGER value" warnings?
|
<p>I'm using MySQL 5.5.37. I want to eliminate the warnings from my update statement, which are shown below ...</p>
<pre><code>update resource r
set grade_id = convert(substring_index(substring_index(
r.description, 'Grade ', -1), ' ', 1), unsigned integer)
where r.description like '% Grade%'
and CONVERT(SUBSTRING_INDEX(SUBSTRING_INDEX(
r.description, 'Grade ', -1), ' ' ,1),UNSIGNED) > 0;
Query OK, 0 rows affected, 7 warnings (0.02 sec)
Rows matched: 1333 Changed: 0 Warnings: 7
mysql> show warnings;
+---------+------+--------------------------------------------------+
| Level | Code | Message |
+---------+------+--------------------------------------------------+
| Warning | 1292 | Truncated incorrect INTEGER value: '' |
| Warning | 1292 | Truncated incorrect INTEGER value: '' |
| Warning | 1292 | Truncated incorrect INTEGER value: '' |
| Warning | 1292 | Truncated incorrect INTEGER value: 'MyCo' |
| Warning | 1292 | Truncated incorrect INTEGER value: 'MyCo' |
| Warning | 1292 | Truncated incorrect INTEGER value: 'MyCo' |
| Warning | 1292 | Truncated incorrect INTEGER value: 'MyCo' |
+---------+------+--------------------------------------------------+
</code></pre>
<p>What I do not understand is how I can rewrite my query differently given that none of the values being updated match what the warnings are complaining about. BElow is my query where I list the distinct values that are being updated ...</p>
<pre><code>mysql> select distinct substring_index(substring_index(
r.description, 'Grade ', -1), ' ', 1)
from resource r
where r.description like '% Grade%'
and CONVERT(SUBSTRING_INDEX(SUBSTRING_INDEX(
r.description, 'Grade ',-1),' ',1),UNSIGNED) > 0;
+-----------------------------------------------------------------------+
| substring_index(substring_index(r.description, 'Grade ', -1), ' ', 1) |

How to use default value in the builder pattern if that value is not passed and also make thread safe?
|
<p>I am trying to use Builder Pattern for my class.. </p>
<p>Below is my Builder class which I have built by following Joshua Bloch version as he showed in Effective Java, 2nd Edition. Our customer will mostly pass <code>userId</code>, <code>clientId</code> always but other fields are optional and they may or may not pass it. Here Preference is an ENUM class having four fields in it.</p>
<pre><code>public final class InputKeys {
private long userid;
private long clientid;
private long timeout = 500L;
private Preference pref;
private boolean debug;
private Map<String, String> parameterMap;
private InputKeys(Builder builder) {
this.userid = builder.userId;
this.clientid = builder.clientId;
this.pref = builder.preference;
this.parameterMap = builder.parameterMap;
this.timeout = builder.timeout;
this.debug = builder.debug;
}
public static class Builder {
protected final long userId;
protected final long clientId;
protected long timeout;
protected Preference preference;
protected boolean debug;
protected Map<String, String> parameterMap;
public Builder(long userId, long clientId) {
this.userId = userId;
this.clientId = clientId;
}
public Builder parameterMap(Map<String, String> parameterMap) {
this.parameterMap = parameterMap;
return this;
}
public Builder preference(Preference preference) {
this.preference = preference;
return this;
}
public Builder debug(boolean debug) {
this.debug = debug;
return this;
}
public Builder timeout(long timeout) {
this.timeout = timeout;
return this;
}
public InputKeys build() {
return new InputKeys(this);
}
}
}
</code></pre>
<p>Below is my ENUM class - </p>
<pre><code>public enum Preference {
PRIMARY,
SECONDARY
}
</code></pre>
<p>I am making a call like this to construct the <code>InputKeys</code> parameter - </p>
<pre><code>InputKeys keys = new InputKeys.Builder(12000L, 33L).build();
System.out.println(keys);
</code></pre>
<p>The only problem here I am seeing is, if the customers are not passing any timeout value, I need to have default timeout value set as 500 always but if they are passing any timeout value then it should override my default timeout value. And this is not working for me as when I see my <code>keys</code> in the debug mode, it always has timeout value as 0.</p>
<p>Is there anything I am missing? And also I am trying to make this class immutable and thread safe.. Is this a thread safe and immutable version of Builder or I have missed something?</p>
<p><strong>UPDATE:-</strong> </p>
<p>Specific scenarios when people will be using this is we have a factory which customers are going to use to make a call to our code. We have a simple interface which one of our class is implementing it and then we have a factory by which we will call a certain method of that implementation which accepts this <code>keys</code> parameter. </p>
<p>So they will be using the below code in there application to make a call and it might be possible they will be running there application in a multithreaded environment.</p>
<pre><code>InputKeys keys = new InputKeys.Builder(12000L, 33L).build();
IClient client = ClientFactory.getInstance();
client.getData(keys);
</code></pre>
<p>And then InputKeys Builder can be used multiple times to construct the keys, it's not one time. Whatever userId and clientId they will be getting they will construct the InputKeys again.</p>

Room: Cannot access database on the main thread since it may potentially lock the UI for a long period of time
|
<p>In the main activity, I have LiveData which contains members and a click listener. If I click on a member, then his ID is passed with intent.putExtra. That ID is later passed on to the method open in this activity. With this activity, I want to see the details of a member. In my MemberInfo activity, I marked a line where my problem lies.

Java 8 stream objects significant memory usage
|
<p>In looking at some profiling results, I noticed that using streams within a tight loop (used instead of another nested loop) incurred a significant memory overhead of objects of types <code>java.util.stream.ReferencePipeline</code> and <code>java.util.ArrayList$ArrayListSpliterator</code>. I converted the offending streams to foreach loops, and the memory consumption decreased significantly. </p>
<p>I know that streams make no promises about performing any better than ordinary loops, but I was under the impression that the difference would be negligible. In this case it seemed like it was a 40% increase.</p>
<p>Here is the test class I wrote to isolate the problem. I monitored memory consumption and object allocation with JFR:</p>
<pre><code>import java.util.ArrayList;
import java.util.List;
import java.util.Optional;
import java.util.Random;
import java.util.function.Predicate;
public class StreamMemoryTest {
private static boolean blackHole = false;
public static List<Integer> getRandListOfSize(int size) {
ArrayList<Integer> randList = new ArrayList<>(size);
Random rnGen = new Random();
for (int i = 0; i < size; i++) {
randList.add(rnGen.nextInt(100));
}
return randList;
}
public static boolean getIndexOfNothingManualImpl(List<Integer> nums, Predicate<Integer> predicate) {
for (Integer num : nums) {
// Impossible condition
if (predicate.test(num)) {
return true;
}
}
return false;
}
public static boolean getIndexOfNothingStreamImpl(List<Integer> nums, Predicate<Integer> predicate) {
Optional<Integer> first = nums.stream().filter(predicate).findFirst();
return first.isPresent();
}
public static void consume(boolean value) {
blackHole = blackHole && value;
}
public static boolean result() {
return blackHole;
}
public static void main(String[] args) {
// 100 million trials
int numTrials = 100000000;
System.out.println("Beginning test");
for (int i = 0; i < numTrials; i++) {
List<Integer> randomNums = StreamMemoryTest.getRandListOfSize(100);
consume(StreamMemoryTest.getIndexOfNothingStreamImpl(randomNums, x -> x < 0));
// or ...
// consume(StreamMemoryTest.getIndexOfNothingManualImpl(randomNums, x -> x < 0));
if (randomNums == null) {
break;
}
}
System.out.print(StreamMemoryTest.result());
}

Clicking a button with Selenium in Python
|
<p><strong>Goal</strong>: use Selenium and Python to search for company name on LinkedIn's search bar THEN click on the "Companies" button in the navigation to arrive to information about companies that are similar to the keyword (rather than individuals at that company). See below for an example. "CalSTRS" is the company I search for in the search bar. Then I want to click on the "Companies" navigation button.</p>

Why does C++ output negative numbers when using modulo?
|
<p><strong>Math</strong>:</p>
<p>If you have an equation like this:</p>
<pre><code>x = 3 mod 7
</code></pre>
<p>x could be ... -4, 3, 10, 17, ..., or more generally:</p>
<pre><code>x = 3 + k * 7
</code></pre>
<p>where k can be any integer. I don't know of a modulo operation is defined for math, but the factor ring certainly is.</p>
<p><strong>Python</strong>:</p>
<p>In Python, you will always get non-negative values when you use <code>%</code> with a positive <code>m</code>:</p>
<pre><code>#!/usr/bin/python
# -*- coding: utf-8 -*-
m = 7
for i in xrange(-8, 10 + 1):
print(i % 7)
</code></pre>
<p>Results in:</p>
<pre><code>6 0 1 2 3 4 5 6 0 1 2 3 4 5 6 0 1 2 3
</code></pre>
<p><strong>C++:</strong></p>
<pre><code>#include <iostream>
using namespace std;
int main(){
int m = 7;
for(int i=-8; i <= 10; i++) {
cout << (i % m) << endl;
}
return 0;
}
</code></pre>
<p>Will output:</p>
<pre><code>-1 0 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 0 1 2 3
</code></pre>
<p><strong>ISO/IEC 14882:2003(E) - 5.6 Multiplicative operators:</strong></p>
<blockquote>
<p>The binary / operator yields the quotient, and the binary % operator
yields the remainder from the division of the first expression by the
second. If the second operand of / or % is zero the behavior is
undefined; otherwise (a/b)*b + a%b is equal to a. If both operands are
nonnegative then the remainder is nonnegative; if not, <strong>the sign of the
remainder is implementation-defined 74)</strong>.</p>
</blockquote>
<p>and</p>
<blockquote>
<p>74) According to work underway toward the revision of ISO C, the
preferred algorithm for integer division follows the rules defined in
the ISO Fortran standard, ISO/IEC 1539:1991, in which the quotient is
always rounded toward zero.</p>

<p>(I couldn't find a free version of <code>ISO/IEC 1539:1991</code>. Does anybody know where to get it from?)</p>
<p>The operation seems to be defined like this:</p>
<p><img src="https://i.stack.imgur.com/8p2MN.png" alt="enter image description here"></p>
<p><strong>Question</strong>: </p>
<p>Does it make sense to define it like that? </p>
<p>What are arguments for this specification? Is there a place where the people who create such standards discuss about it? Where I can read something about the reasons why they decided to make it this way?</p>
<p>Most of the time when I use modulo, I want to access elements of a datastructure. In this case, I have to make sure that mod returns a non-negative value. So, for this case, it would be good of mod always returned a non-negative value.
(Another usage is the <a href="http://en.wikipedia.org/wiki/Euclidean_algorithm#Implementations" rel="noreferrer">Euclidean algorithm</a>. As you could make both numbers positive before using this algorithm, the sign of modulo would matter.)</p>
<p><strong>Additional material</strong>: </p>

Can an Airflow task dynamically generate a DAG at runtime?
|
<p>I have an upload folder that gets irregular uploads. For each uploaded file, I want to spawn a DAG that is specific to that file.</p>
<p>My first thought was to do this with a FileSensor that monitors the upload folder and, conditional on presence of new files, triggers a task that creates the separate DAGs. Conceptually:</p>
<pre><code>Sensor_DAG (FileSensor -> CreateDAGTask)
|-> File1_DAG (Task1 -> Task2 -> ...)
|-> File2_DAG (Task1 -> Task2 -> ...)
</code></pre>
<p>In my initial implementation, <code>CreateDAGTask</code> was a <code>PythonOperator</code> that created DAG globals, by placing them in the global namespace (<a href="https://stackoverflow.com/a/44127627/2114580">see this SO answer</a>), like so:</p>
<pre class="lang-py prettyprint-override"><code>from airflow import DAG
from airflow.operators.dummy_operator import DummyOperator
from airflow.operators.python_operator import PythonOperator
from airflow.contrib.sensors.file_sensor import FileSensor
from datetime import datetime, timedelta
from pathlib import Path
UPLOAD_LOCATION = "/opt/files/uploaded"
# Dynamic DAG generation task code, for the Sensor_DAG below
def generate_dags_for_files(location=UPLOAD_LOCATION, **kwargs):
dags = []
for filepath in Path(location).glob('*'):
dag_name = f"process_{filepath.name}"
dag = DAG(dag_name, schedule_interval="@once", default_args={
"depends_on_past": True,
"start_date": datetime(2020, 7, 15),
"retries": 1,
"retry_delay": timedelta(hours=12)
}, catchup=False)
dag_task = DummyOperator(dag=dag, task_id=f"start_{dag_name}")
dags.append(dag)
# Try to place the DAG into globals(), which doesn't work
globals()[dag_name] = dag
return dags
</code></pre>
<p>The main DAG then invokes this logic via a <code>PythonOperator</code>:</p>
<pre><code># File-sensing DAG
default_args = {
"depends_on_past" : False,
"start_date" : datetime(2020, 7, 16),
"retries" : 1,
"retry_delay" : timedelta(hours=5),
}
with DAG("Sensor_DAG", default_args=default_args,
schedule_interval= "50 * * * *", catchup=False, ) as sensor_dag:
start_task = DummyOperator(task_id="start")
stop_task = DummyOperator(task_id="stop")
sensor_task = FileSensor(task_id="my_file_sensor_task",
poke_interval=60,
filepath=UPLOAD_LOCATION)
process_creator_task = PythonOperator(
task_id="process_creator",
python_callable=generate_dags_for_files,
)
start_task >> sensor_task >> process_creator_task >> stop_task
</code></pre>
<p>But that doesn't work, because by the time <code>process_creator_task</code> runs, the globals have already been parsed by Airflow. New globals after parse time are irrelevant.</p>
<h2>Interim solution</h2>
<p>Per <a href="https://stackoverflow.com/questions/39133376/airflow-dynamic-dag-and-task-ids">Airflow dynamic DAG and task Ids</a>, <s>I can achieve what I'm trying to do by omitting the <code>FileSensor</code> task altogether and just letting Airflow generate the per-file task at each scheduler heartbeat, replacing the Sensor_DAG with just executing <code>generate_dags_for_files</code>:</s> Update: Nevermind -- while this does create a DAG in the dashboard, actual execution runs into the <a href="https://stackoverflow.com/questions/57472942/dag-seems-to-be-missing">"DAG seems to be missing"</a> issue:</p>
<pre class="lang-py prettyprint-override"><code>generate_dags_for_files()
</code></pre>
<p>This does mean that I can no longer regulate the frequency of folder polling with the <code>poke_interval</code> parameter of <code>FileSensor</code>; instead, Airflow will poll the folder every time it collects DAGs.</p>
<p>Is that the best pattern here?</p>

Hibernate encodes wrong while persisting objects [UTF-8]

<p>I'm facing with UTF-8 encoding problem while persisting my model objects. In Turkish '<strong>ı</strong>' is a letter. Also there're some other Turkish characters that is included in UTF-8 encoding. While I persist my model objects, all '<strong>ı</strong>' characters are persisted as '<strong>?</strong>' to DB. I'm using <strong>MySQL 5.5 on Ubuntu Linux 64-bit OS</strong>. Also I've already set hibernate & c3p0 connection encoding property to UTF-8 too. When I debug, the data comes from client is true. </p>

How do you use AsParallel with the async and await keywords?
|
<p>I was looking at someone sample code for async and noticed a few issues with the way it was implemented. Whilst looking at the code I wondered if it would be more efficient to loop through a list using as parallel, rather than just looping through the list normally.</p>
<p>As far as I can tell there is very little difference in performance, both use up every processor, and both talk around the same amount of time to completed. </p>
<p>This is the first way of doing it</p>
<pre><code>var tasks= Client.GetClients().Select(async p => await p.Initialize());
</code></pre>
<p>And this is the second</p>
<pre><code>var tasks = Client.GetClients().AsParallel().Select(async p => await p.Initialize());
</code></pre>
<p>Am I correct in assuming there is no difference between the two?</p>
<p>The full program can be found below</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
RunCode1();
Console.WriteLine("Here");
Console.ReadLine();
RunCode2();
Console.WriteLine("Here");
Console.ReadLine();
}
private async static void RunCode1()
{
Stopwatch myStopWatch = new Stopwatch();
myStopWatch.Start();
var tasks= Client.GetClients().Select(async p => await p.Initialize());
Task.WaitAll(tasks.ToArray());
Console.WriteLine("Time ellapsed(ms): " + myStopWatch.ElapsedMilliseconds);
myStopWatch.Stop();
}
private async static void RunCode2()
{
Stopwatch myStopWatch = new Stopwatch();
myStopWatch.Start();
var tasks = Client.GetClients().AsParallel().Select(async p => await p.Initialize());
Task.WaitAll(tasks.ToArray());
Console.WriteLine("Time ellapsed(ms): " + myStopWatch.ElapsedMilliseconds);
myStopWatch.Stop();
}
}
class Client
{
public static IEnumerable<Client> GetClients()
{
for (int i = 0; i < 100; i++)
{
yield return new Client() { Id = Guid.NewGuid() };
}
}
public Guid Id { get; set; }
//This method has to be called before you use a client
//For the sample, I don't put it on the constructor
public async Task Initialize()
{
await Task.Factory.StartNew(() =>
{
Stopwatch timer = new Stopwatch();
timer.Start();
while(timer.ElapsedMilliseconds<1000)
{}
timer.Stop();
});
Console.WriteLine("Completed: " + Id);
}
}

How do I display custom error pages in Asp.Net Mvc 3?
|
<p>I want all 401 errors to be be redirected to a custom error page. I have initially setup the following entry in my web.config. </p>
<pre><code><customErrors defaultRedirect="ErrorPage.aspx" mode="On">
<error statusCode="401" redirect="~/Views/Shared/AccessDenied.aspx" />
</customErrors>
</code></pre>
<p>When using IIS Express I receive the stock IIS Express 401 error page.</p>
<p>In the event when I do not use IIS Express a blank page is returned. Using Google Chrome's Network tab to inspect the response, I see that while the page is blank a 401 status is returned in the headers</p>
<p>What I have tried thus far is using suggestions from <a href="https://stackoverflow.com/questions/2480006/what-is-the-difference-between-customerrors-and-httperrors">this SO answer</a> since I am using IIS Express but to no avail. I have tried using a combination <code><custom errors></code> and <code><httpErrors></code> with no luck - the standard error or blank page is still displayed. </p>
<p>The <code>httpErrors</code> section looks like this at the moment based on <a href="https://serverfault.com/questions/123729/iis-is-overriding-my-response-content-if-i-manually-set-the-response-statuscode/124074#124074">the link</a> from the <a href="https://stackoverflow.com/questions/2480006/what-is-the-difference-between-customerrors-and-httperrors">above SO question</a> ( I also found another very <a href="https://stackoverflow.com/questions/6512904/how-to-create-custom-404-error-pages-in-asp-net-mvc-3">promising answer</a> however no luck - blank response) </p>
<pre><code><system.webServer>
<httpErrors errorMode="DetailedLocalOnly" existingResponse="PassThrough" >
<remove statusCode="401" />
<error statusCode="401" path="/Views/Shared/AccessDenied.htm" />
</httpErrors>
<!--
<httpErrors errorMode="Custom"
existingResponse="PassThrough"
defaultResponseMode="ExecuteURL">
<remove statusCode="401" />
<error statusCode="401" path="~/Views/Shared/AccessDenied.htm"
responseMode="File" />
</httpErrors>
-->
</system.webServer>
</code></pre>
<p>I have even modified the <code>applicationhost.config</code> file and modified <code><httpErrors lockAttributes="allowAbsolutePathsWhenDelegated,defaultPath"></code> to <code><httpErrors lockAttributes="allowAbsolutePathsWhenDelegated"></code> based on information from <a href="http://www.iis.net/ConfigReference/system.webServer/httpErrors" rel="nofollow noreferrer">iis.net</a>. During the course of my endeavours I also managed to stumbled upon this error as described in <a href="https://stackoverflow.com/questions/6390886/500-19-error-with-iis7-5">another SO question</a>. </p>
<p>How do I display custom error pages in Asp.Net Mvc 3?</p>

jQuery populate form from json

how to make webpack typescript react webpack-dev-server configuration for auto building and reloading page

<p>So the app.js was created and webpack-dev-server started working and opened page in the browser. Everything goes fine by far. But when I change the text in my index.tsx and save this file nothing changes, I tried to refresh the browser page, the text remains the same and app.js is not rebuilt.
To make the text change I have to rebuild app.js with webpack by hand again from the terminal by issuing "npm run build". </p>
<p>How to improve my workflow to make the changes in my /src folder be reflected automatically in my dist/build/app.js file without having to manually rebuild it?</p>

How to test characters in a string [Assembly]
|
<p>I'm writing a program to search for vowels inside a string, but I'm having trouble testing the individual characters inside the string, I have the basic concept down and I've done this before using C++ and Python, but I don't know how to code it in Assembly.</p>
<p>I'm going to use a switch to add up and test the individual characters, and I know that I need to use a loop to cycle through all the characters, but I'm stuck on actually testing individual characters. (this isn't what I have coded per say but an illustrative example)</p>
<pre><code>max_length dd 40
user_input resd max_length
str_len dw $ - user_input
GetStr user_input ; "I am a boy"
mov ecx, str_len
</code></pre>
<p>And this is where I get stuck. How would you test the individual characters of <code>user_input</code> ? </p>
<p>In C++ you would have something like <code>if(user_input[0] = 'Y')</code>, but how do I translate that type of instruction to assembly (user_input[0])</p>
<p>I understand that it does not work this way in assembly but hopefully this will clear some things up.</p>
<pre><code>str_len DW $ - user_input
max_length EQU 40
jump_table:
DD case_0
DD case_1
DD case_2
DD case_3
DD case_4
DD case_5
.UDATA
user_input resd max_length
_main:
push ebp
mov ebp, esp
switch:
xor eax,eax
xor ebx,ebx
PutStr prompt
GetStr user_input
mov ecx, [str_len]
mov esi, user_input
read:
mov al, byte [esi+ebx]
or al, 20h
cmp al, 'a'
je [jump_table]
cmp al, 'e'
je [jump_table+4]
cmp al, 'i'
je [jump_table+8]
cmp al, 'o'
je [jump_table+12]
cmp al, 'u'
je [jump_table+16]
cmp ecx, 0
je [jump_table+20]
inc ebx
jmp read
</code></pre>
<p>this is where I am now, as I commented further down I'm getting an error linked to <code>str_len</code></p>
<p>This is all working, I just need to clear the buffer, Thanks!

Why is my SQL Server query failing?

return $connect;
}
</code></pre>
<p>Above is the code. The first query/fetch_assoc works perfectly fine, however the next 2 queries fail and I cannot figure out why. Here is the error statement that shows up from php:</p>
<blockquote>

<p>Warning: mssql_fetch_assoc(): supplied argument is not a valid MS SQL-result resource in /srv/www/htdocs/agreement.php on line 52</p>
</blockquote>
<p>The error clearly centers around the fact that the query is not executing. In my database I have a table called Issues and a table called ApplicationInfo so I am unsure why it is telling me that they are invalid objects.</p>

How to use docker volume to deploy war / jar in Tomcat
|
<p>Is it possible to deploy some java war or jar file in Tomcat? I looking for a lot of tutorials and the only solution I found is copy project war file into <code>/usr/local/tomcat/webapps/</code>.</p>
<p>I actually used that solution but I would like to improve my dockerisation. My primary goal is when I run my 2 images (application in tomcat and db image) with docker-compose I want to use my local war file of target folder in tomcat, and, when I build war again after the code changed, that change will be reflected without stopping containers, removing, and rebuilding. Can you help to do that? My attempts failed. I want it just for development purpose.</p>
<p>Here is my docker-compose.yml</p>
<pre><code>version: '3'
services:
tomcat-service:
build:
context: ../
dockerfile: docker/app/Dockerfile
volumes:
- D:\myproj\target\app.war:/usr/local/tomcat/webapps/ROOT.war
ports:
- "8080:8080"
depends_on:
- "db-service"
db-service:
build: ./database
ports:
- "5433:5432"
</code></pre>
<p>and Dockerfile for that tomcat</p>
<pre><code>FROM tomcat:8.0-jre8
RUN rm -rvf /usr/local/tomcat/webapps/ROOT
COPY ./docker/app/context.xml /usr/local/tomcat/conf/
# with following copy command it works, but when I rebuild war file, I need stop docker-compose and build and run it again .. I want use volume instead of copy war
#COPY ./pnp-web/target/pnp.war /usr/local/tomcat/webapps/ROOT.war
EXPOSE 8080
CMD ["catalina.sh", "run"]
</code></pre>
<p>With configuration above applicaton starts, but when I run <code>mvn clean package</code> application is not loaded anymore</p>
<p>EDIT</p>
<p>I checked log of tomcat container and I found this error:</p>

CloudFormation: Create resources if they do not exist, but do not delete them
|
<p>I have the following CloudFormation template. (It is based off default the template created for running C# Web API in AWS Lambda, but that may not be relevant.)</p>
<p>It creates an AWS Lambda function. The template also creates an IAM Role and a DynamoDB table if the names of existing resources are not supplied as arguments.</p>
<p>That part works. If no names are supplied for the role and table, they are created.</p>
<p><strong>The problem exists when I run the template a second time to perform updates:</strong> at this point, my role and table exist, so I provide the names as arguments. However, when CloudFormation runs the second time, the resources it created the first time (the role and table) are deleted.</p>
<p><strong>Is there some way to set up the template such that it will create new resources if they don't exist, but not delete them if they are already present?</strong></p>
<p>I haven't done a lot with CloudFormation, but I did go through the documentation. The closest I found was <a href="http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html" rel="noreferrer">setting a stack policy</a>, but it doesn't seem to be part of the template. It looks like I would have to do this in the management console after the fact.</p>

spring Java config for excel view resolver

<p>I have a spring java config based web app with (jsp) view resolver.
Now i want to show a excel sheet with some data when user clicks on excel icon in app.
All over internet i only found xml based spring config for excel view with which i am not familiar with.
I decoded to some extent and came pretty close to get my task done. Below is what i got.</p>

<p>I dont know how to avoid it from forwarding it to xl.jsp. I am sure view resolver is making it into jsp view. Can someone point how can i fix it.</p>
<p><strong>EDIT</strong></p>
<p>I saw this xml equivalent config online. Not sure how to make it java config:</p>

XmlViewResolver resolver = new XmlViewResolver();
resolver.setOrder(1);
resolver.setLocation(**WHAT SHOULD BE HERE**);
}
</code></pre>
<p>I dont know what to put in location. I cant give string. i dont have views.xml as i am use java configs</p>

What causes SignalR to receive net::ERR_CONNECTION_RESET on connect?
|
<p>I have a simple SingulaR example that I've added to a legacy ASP.Net MVC application.</p>
<p>Here are the various parts:</p>
<p><strong>OWIN Startup class</strong></p>
<pre><code>[assembly: OwinStartup(typeof (Startup))]
namespace MyApp.Web
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}
}
</code></pre>
<p><strong>SignalR Hub</strong></p>
<pre><code>using System.Collections.Generic;
using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
namespace MyApp.Web
{
[HubName("podService")]
public class PodServiceHub : Hub
{
public PodServiceHub()
{
;
}
public IEnumerable<string> GetMessages()
{
return new[] {"blah", "blah", "blah"};
}
}
}
</code></pre>
<p><strong>Server-side facade</strong></p>
<pre><code>using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
namespace MyApp.Web
{
public class PodService
{
PodService(IHubConnectionContext<dynamic> clients)
{
Clients = clients;
}
public PodService()
: this(GlobalHost.ConnectionManager.GetHubContext<PodServiceHub>().Clients)
{
}
IHubConnectionContext<dynamic> Clients { get; set; }
public void SendMessageToClient(string message)
{
Clients.All.doSomething(message);
}
}
}
</code></pre>
<p><strong>Portions of startup Javascript:</strong></p>
<pre><code> var podService = $.connection.podService;
...
$.extend(podService.client, {
doSomething: function(message) {
console.log("received message:" + message);
}
});
// test
$.connection.hub.start()
.done(function() {
podService.server.getMessages()
.done(function(messages) {
console.log("received message:" + message);
});
});
</code></pre>
<p>Within one of the controllers called by the first page:</p>
<pre><code>_podService.SendMessageToClient("Hello from the server!");
</code></pre>
<p>Upon executing the application, the following error is displayed in the console of Chrome's dev tools:</p>
<p>WebSocket connection to 'ws://localhost:62025/signalr/connect?transport=webSockets&clientProtocol=1.5&connectionToken=02LJFqBcRBWKXAOlaSwgMPWG0epV7AFl19gNjFCvA0dxD2QH8%2BC9V028Ehu8fYAFN%2FthPv65JZKfK2MgCEdihCJ0A2dMyENOcdPkhDzEwNB2WQ1X4QXe1fiZAyMbkZ1b&connectionData=%5B%7B%22name%22%3A%22podservice%22%7D%5D&tid=6' failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET</p>
<p>After this error, however, the podService.server.getMessages() returns with the message from the server printing ["blah", "blah", "blah"] to the console and subsequently the doSomething client function is invoked printing "received message: Hello from the server!".</p>
<p>The calls from both the client and the server are transmitting data, so this error doesn't appear to be breaking the app. It definitely seems to be an issue though. The code above was based upon the sample code generated by the Microsoft.AspNet.SignalR.Sample NuGet package which doesn't display the same behavior. The only difference I'm aware of between my example and NuGet-based sample is that I've added this to a legacy MVC app vs. a pure OWIN-based app. Based upon a comment I read <a href="https://stackoverflow.com/questions/26273700/signalr-without-owin">on this SO question</a> this shouldn't be an issue.</p>
<p>So, what's wrong with this example usage and/or what could be causing the connection reset?</p>

Want to create a table using XSL/XML
|
<p>I’m trying to create a table using XSL/XML. I'm new to XSL and XML, so go easy on me please
I’m having a bit of trouble with a few things.
This is my XML file:</p>
<pre><code><List>
<Classification>
<Class>
<Label>Milk</Label>
<NumberZone>1</NumberZone>
<Zone>
<Label>Milk1</Label>
<Frontier>500</Frontier>
</Zone>
<Zone>
<Label>Milk2</Label>
<Frontier>600</Frontier>
</Zone>
<Zone>
<Label>Milk3</Label>
<Frontier>600</Frontier>
</Zone>
<Zone>
<Label>Milk4</Label>
<Frontier>700</Frontier>
</Zone>
<image>
<File>milk.jpg</File>
</image>
</Class>
<Class>
<Label>Water</Label>
<NumberZone>2</NumberZone>
<Zone>
<Label>Water1</Label>
<Frontier>800</Frontier>
</Zone>
<Zone>
<Label>Water2</Label>
<Frontier>900</Frontier>
</Zone>
<image>
<File>water.jpg</File>
</image>
</Class>
<Class>
<Label>Juice</Label>
<NumberZone>3</NumberZone>
<Zone>
<Label>Juice1</Label>
<Frontier>950</Frontier>
</Zone>
<Zone>
<Label>Juice2</Label>
<Frontier>990</Frontier>
</Zone>
<image>
<File>juice.jpg</File>
</image>
</Class>
</Classification>
</List>
</code></pre>
<p>It normally is longer, but I cut out some parts.</p>
<p>I want my table to look like this:</p>
<ul>
<li>First column: Milk, Water, Juice...</li>
<li>Second column: I want the images.</li>
<li>Third column: Milk1, Water1, Juice1. </li>
<li>Fourth column: Milk2, Water2, Juice2.</li>
<li>(And so on).</li>
</ul>
<p>So far I have this:</p>
<pre><code><table border="1">
<tr><th>Column 1</th><th>Image</th><th>Column 3</th></tr>
<xsl:for-each select="Classification/Class">
<tr>
<td><em><xsl:value-of select="Label" /></em></td>
<td>
<xsl:attribute name="src">
<xsl:value-of select="image/File"/>
</xsl:attribute>
</td>
<td><xsl:value-of select="Zone/Label"/></td>
<td colspan="1"><xsl:value-of select="Zone/Label"/></td>
<td colspan="1"><xsl:value-of select="Zone/Label"/></td>
</tr>
</xsl:for-each>
</table>
</code></pre>
<ul>
<li>This displays the first column perfectly with Milk, Water, and Juice.</li>
<li>The second column doesn't work, it's just blank. The image won't appear in the table, any idea on how to fix this?*</li>
<li>The third column also works perfectly showing Milk1, Water1, Juice1.</li>
<li>The fourth column doesn't work, obviously, because I'm using the same value-of as in the third column. I don't know how to get Milk2, Water2, and Juice2 to show in that column, since it uses the same element name (being Zone/Label)</li>
</ul>
<p><strong>So there's two thing I need to fix: I need to fix the second column to actually show the image in each boxes.
I also need to fix the fourth column to show Milk2, Water2, and Juice2.
My main problem for now is to get the fourth column to work, I really don't understand how to display Milk2, Water2, etc.</strong></p>
<p>I would also like to add either radio buttons, or check boxes later on in each cell, so I could use JavaScript in my web page. I feel like each box would need a different ID, so I'm not sure how to achieve that using XSL, since it just does a "loop" through the XML file, so I'm not sure how I would add a radio button, or a check box in each cell. * This isn't as important for now, I'll work on that after I'd rather have help with what I mentioned before, but this would be helpful too.</p>
<p>EDIT:</p>
<p>I have two problems.
I managed to add check boxes by doing something like this:</p>
<pre><code><td colspan="1"><input type="checkbox" name="Zone1" id="Zone1" /><xsl:value-of select="Zone[1]/Label"/></td>
<td colspan="1"><input type="checkbox" name="Zone2" id="Zone1" /><xsl:value-of select="Zone[2]/Label"/></td>
<td colspan="1"><input type="checkbox" name="Zone3" id="Zone1"/> <xsl:value-of select="Zone[3]/Label"/></td>
<td colspan="1"><input type="checkbox" name="Zone4" id="Zone1" /><xsl:value-of select="Zone[4]/Label"/></td>
</code></pre>
<p>The problem is, I think every elements in each column will have the same ID, am I right? How do I change it so they all have a different ID?</p>
<p>Also, it can't be seen from the XML file in my question, but later on there would only be, for example, Milk4. meaning I would want the cells for Water4 and Juice4 to dissapear completely, but it's still there, empty with a check box.</p>

Python. SQL Alchemy NotImplementedError: Operator 'getitem' is not supported on this expression

<p>Then show that Div when the submit button is clicked</p>
<p>My Controller looks like the following</p>
<pre><code>public class PasswordController : Controller

public ActionResult Search(string searchString)

<p>At the moment the div is constantly shown and updates when the submit button is pressed but I want to hide that div until someone presses the submit button then it can show.</p>
<p>Thanks in advance for the help.</p>

Watch date input value and use it with v-model
|
<p>I tried for 4 days to get a stupid date from the input, that the user selected. Looks probably simple but believe me that I ask here because I run out of solutions.</p>
<p>I have a page/component AddNewEvent and inside this input where the user adds the date and time. I have to get it in my v-model so I can send it back to database.</p>
<p>I use bootstrap 4 input <code>type="datetime-local"</code> to get the date and time. I tried to use some vue plugins for date but all are based on bootstrap 3 and in the project is bootstrap 4.</p>
<p>Inside template:</p>
<pre><code><div class="form-group">
<label class="eda-form-label" for="event-name">Event Name <span>(Max characters number is 60)</span></label>
<input type="text" class="eda-form-input" v-model="newEvent.eventName">
</div>
<div class="form-group">
<label class="eda-form-label" for="exampleTextarea">Event Description <span>(Max characters number is 2000)</span></label>
<textarea class="eda-form-input" rows="3" v-model="newEvent.description"></textarea>
</div>
<div class="form-group">
<div class="row">
<div class="col-6 ">
<label class="eda-form-label" for="start-time">START TIME</label>
<input class="form-control" type="datetime-local" v-model="dateNow">
</div>{{createdDate(value)}}
<div class="col-6">
<label class="eda-form-label" for="end-time">END TIME</label>
<input class="form-control" type="datetime-local" v-model="dateEnd">
</div>
</div>
</div>
</code></pre>
<p>In the script:</p>
<pre><code>data() {
return {
dateNow: '',
value: '',
oldValue: ''
}
},
watch: {
dateNow(val, oldVal) {
this.value = val;
this.oldValue = oldVal;
}
},
methods: {
createEvent(){
axios.post("/event", this.newEvent,
{'headers':{'X-AUTH-TOKEN': localStorage.token}},
{'headers':{'Content-Type': 'application/json'}})
.then((response) => {
alertify.success("Success! You added a new the user");
this.$router.push('/events');
})
.catch((response) => {
alertify.error();
})
},
}
</code></pre>
<p>If I use in the input, how is right now, <code>v-model="dateNow"</code> works. I can see when I select date, time am/pm shows me the seleted date. But I have to use it like this </p>
<p><code>v-model="newEvent.dateNow"</code> </p>
<p><code>v-model="newEvent.dateEnd"</code> </p>
<p>so I can add it to newEvent and send the whole obj back to database. </p>
<p>createdDate is a function that transforms the date in a real date. It's only for testing, because I have to send the date in ms back to database.</p>
<p>Someone please show me what I do wrong, because I'm not so very advance in vuejs.</p>

How do I debug macros?
|
<p>So I've got the following macro code I'm trying to debug. I've taken it from the <a href="http://doc.rust-lang.org/book/macros.html" rel="noreferrer" title="The Rust Programming Language Book">Rust Book</a> under the section "The deep end". I renamed the variables within the macro to more closely follow <a href="http://esolangs.org/wiki/Bitwise_Cyclic_Tag" rel="noreferrer" title="Bitwise Cyclic Tag">this</a> post.</p>
<p>My goal is to have the program print out each line of the BCT program. I'm well aware that this is very compiler heavy.</p>
<p>The only error rustc is giving me is:</p>
<pre><code>user@debian:~/rust/macros$ rustc --pretty expanded src/main.rs -Z unstable-options > src/main.precomp.rs
src/main.rs:151:34: 151:35 error: no rules expected the token `0`
src/main.rs:151 bct!(0, 1, 1, 1, 0, 0, 0; 1, 0);
</code></pre>
<p>What steps can I take to figure out <strong><em>where</em></strong> in the macro the problem is coming from?</p>
<p>Here's my code:</p>
<pre><code>fn main() {
{
// "Bitwise Cyclic Tag" automation through macros
macro_rules! bct {
// cmd 0: 0 ... => ...
(0, $($program:tt),* ; $_head:tt)
=> (bct_p!($($program),*, 0 ; ));
(0, $($program:tt),* ; $_head:tt, $($tail:tt),*)
=> (bct_p!($($program),*, 0 ; $($tail),*));
// cmd 1x: 1 ... => 1 ... x
(1, $x:tt, $($program:tt),* ; 1)
=> (bct_p!($($program),*, 1, $x ; 1, $x));
(1, $x:tt, $($program:tt),* ; 1, $($tail:tt),*)
=> (bct_p!($($program),*, 1, $x ; 1, $($tail),*, $x));
// cmd 1x: 0 ... => 0 ...
(1, $x:tt, $($program:tt),* ; $($tail:tt),*)
=> (bct_p!($($program),*, 1, $x ; $($tail),*));
// halt on empty data string
( $($program:tt),* ; )
=> (());
}
macro_rules! print_bct {
($x:tt ; )
=> (print!("{}", stringify!($x)));
( ; $d:tt)
=> (print!("{}", stringify!($d)));
($x:tt, $($program:tt),* ; )
=> {
print!("{}", stringify!($x));
print_bct!($program ;);
};
($x:tt, $($program:tt),* ; $($data:tt),*)

print!("{}", stringify!($x));
print_bct!($program ; $data);

bct!($($program),* ; );

println!("");

Making Sidebar with material-ui

<p>i'm learning material-ui by making the right navigation menu like this one: <a href="http://demo.geekslabs.com/materialize/v3.1/" rel="noreferrer">http://demo.geekslabs.com/materialize/v3.1/</a> or least like this: <a href="http://www.material-ui.com/#/components/app-bar" rel="noreferrer">http://www.material-ui.com/#/components/app-bar</a></p>
<p>I'm using Drawer to make my sidebar, the problem is when the sidebar is toggled, it hides the content on the right. I want when my sidebar is toggled, it took place and push the content to the right and both sidebar and content got their own scrollbar. Here is my current code:</p>

<MenuItem onTouchTap={this.handleClose}>Menu Item 2</MenuItem>
</Drawer>
</div>
</MuiThemeProvider>
);
}
}

<p>My Layout.js:</p>
<pre><code>import React, { PropTypes } from 'react';

how to pass value data between classes/activity in Android?
|
<p>For example i have activity1, activity2, activity3 and lastly valueAllActivity?
how do I pass the data from activity1, activity2, activity3 to --> valueAllActivity?</p>
<p>to pass INT value in each activity to valueAllActivity.</p>
<p>I am very new in developing Android program, so if anyone could guide, it would be an honor :)

Dynamically create a treeview
|
<p>I am trying to create a treeview dynamically using c# and asp.net.</p>
<p>I have created a lazy load treeview using the populate ondemand attribute. </p>
<pre><code>> <asp:TreeView ID="treeView1" runat="server"
> OnTreeNodePopulate="treeview1_TreeNodePopulate"></asp:TreeView>
</code></pre>
<p>Behind code I have loaded my data but initially I populate the parent nodes. What I want to achieve is when i click on parent node I then do a postback and then populate its child and then again populate its child's and so now. I have thousands of data so i dont want all data to be populated due to performance. So thats the reason why I only want to populate the node childs based on selected node. See example below:</p>
<pre><code>>Peter
- - >user1
- - >user2
- - >user3
- - >userPassword
- - >userId
>john
>david
>Jack
- - >user1
- - >user2
- - >userpassword
- - >userId
- - >Permissions
>Laura
- - > admin
- - > permissions
-- > user1
-- > user2
- - >userpassword
- - >userId
- - >Permissions
>...
>...
>...
</code></pre>
<p>As you can see there can be multiple parent nodes and multiple layers. These will be populated dynically based on what i pass in to DB. Everytime i click on node it will expand the node and populate its child using postback and then when you click on its child again it will do a postback and populate its child again etc. So i wanted help on how to create a dynamic treeview.</p>
<p>c# :</p>
<pre><code>private void LoadTreeview()
{
//Load data
// Get data from DB.
//loop through the list and build its parent nodes.
foreach (var dxm in list)
{
TreeNode tnParent = CheckNodeExist(dxm.Node); //I check to see if exists.
if (tnParent== null)
{
TreeNode tn = new TreeNode();
tn.Text = dxm.Node;
tn.Value = dxm.Id.ToString();
tn.SelectAction = TreeNodeSelectAction.None;
tn.Collapse();
treeView1.Nodes.Add(tn);
tn.PopulateOnDemand = true; //lazy load
tnParent= tn;
}
}
</code></pre>
<p>This method above is called on page load.</p>
<p>On TreeNodePopulateEvent: (when a node is clicked on)</p>
<pre><code>protected void treeview1_TreeNodePopulate(object sender, TreeNodeEventArgs e)
{
ICollection<ITEMS> list = new Collection<ITEMS>();
list = GetData(e.Node.Text); //pass in the node you have selected this will go and check in DB if the node does have any child nodes. If so will return with child nodes.
foreach (var dxm in list)
{
TreeNode tnChild = CheckNodeExist(dxm.Node);
if (tnChild == null)
{
TreeNode tn = new TreeNode();
tn.Text = dxm.Node;
tn.Value = dxm.Id.ToString();
tn.SelectAction = TreeNodeSelectAction.None;
tn.Collapse();
tn.PopulateOnDemand = true;
tnChild = tn;
tnChild.ChildNodes.Add(tnChild);
}
}
}

Spring Integration - how to send POST parameters with http outbound-gateway
|
<p>I'm trying to put together a really simple HTTP POST example using Spring Integration and a http outbound-gateway.<br>
I need to be able to send a HTTP POST message with some POST parameters, as I would with <code>curl</code>:</p>
<pre><code>$ curl -d 'fName=Fred&sName=Bloggs' http://localhost
</code></pre>
<p>I can get it working (without the POST parameters) if I send a simple <code>String</code> as the argument to the interface method, but I need to send a pojo, where each property of the pojo becomes a POST parameter.</p>
<p>I have the following SI config:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:int="http://www.springframework.org/schema/integration"
xmlns:int-http="http://www.springframework.org/schema/integration/http"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd
http://www.springframework.org/schema/integration/http http://www.springframework.org/schema/integration/http/spring-integration-http.xsd">
<int:gateway id="requestGateway"
service-interface="RequestGateway"
default-request-channel="requestChannel"/>
<int:channel id="requestChannel"/>
<int-http:outbound-gateway request-channel="requestChannel"
url="http://localhost"
http-method="POST"
expected-response-type="java.lang.String"/>
</beans>
</code></pre>
<p>My <code>RequestGateway</code> interface looks like this:</p>
<pre><code>public interface RequestGateway {
String echo(Pojo request);
}
</code></pre>
<p>My <code>Pojo</code> class looks like this:</p>
<pre><code>public class Pojo {
private String fName;
private String sName;
public Pojo(String fName, String sName) {
this.fName = fName;
this.sName = sName;
}
.... getters and setters
}
</code></pre>
<p>And my class to kick it all off looks like this:</p>
<pre><code>public class HttpClientDemo {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("/si-email-context.xml");
RequestGateway requestGateway = context.getBean("requestGateway", RequestGateway.class);
Pojo pojo = new Pojo("Fred", "Bloggs");
String reply = requestGateway.echo(pojo);
System.out.println("Replied with: " + reply);
}
}
</code></pre>
<p>When I run the above, I get:</p>
<pre><code>org.springframework.web.client.RestClientException: Could not write request: no suitable HttpMessageConverter found for request type [Pojo] and content type [application/x-java-serialized-object]
</code></pre>
<p>I've googled a lot for this, but cannot find any examples of sending HTTP POST parameters with an outbound-gateway (I can find lots about setting HTTP Headers, but that's not what I'm trying to do here)<br>
The only thing I did find was <a href="https://stackoverflow.com/questions/20083604/spring-integration-how-to-pass-post-request-parameters-to-http-outbound">spring-integration: how to pass post request parameters to http-outbound</a> but it's a slightly different use case as the OP was trying to send a JSON representation of his pojo which I am not, and the answer talks about setting headers, not POST parameters.</p>
<p>Any help with this would be very much appreciated;<br>
Thanks<br>
Nathan</p>

Getting Spark, Python, and MongoDB to work together
|
<p>I'm having difficulty getting these components to knit together properly. I have Spark installed and working successfully, I can run jobs locally, standalone, and also via YARN. I have followed the steps advised (to the best of my knowledge) <a href="https://github.com/mongodb/mongo-hadoop/wiki/Spark-Usage" rel="nofollow noreferrer">here</a> and <a href="https://github.com/mongodb/mongo-hadoop/blob/master/spark/src/main/python/README.rst" rel="nofollow noreferrer">here</a></p>
<p>I'm working on Ubuntu and the various component versions I have are</p>
<ul>
<li><strong>Spark</strong> spark-1.5.1-bin-hadoop2.6</li>
<li><strong>Hadoop</strong> hadoop-2.6.1</li>
<li><strong>Mongo</strong> 2.6.10</li>
<li><strong>Mongo-Hadoop connector</strong> cloned from <a href="https://github.com/mongodb/mongo-hadoop.git" rel="nofollow noreferrer">https://github.com/mongodb/mongo-hadoop.git</a></li>
<li><strong>Python</strong> 2.7.10</li>
</ul>
<p>I had some difficulty following the various steps such as which jars to add to which path, so what I have added are</p>
<ul>
<li>in <code>/usr/local/share/hadoop-2.6.1/share/hadoop/mapreduce</code> <strong>I have added</strong> <code>mongo-hadoop-core-1.5.0-SNAPSHOT.jar</code></li>
<li>the following <strong>environment variables</strong>
<ul>
<li><code>export HADOOP_HOME="/usr/local/share/hadoop-2.6.1"</code></li>
<li><code>export PATH=$PATH:$HADOOP_HOME/bin</code></li>
<li><code>export SPARK_HOME="/usr/local/share/spark-1.5.1-bin-hadoop2.6"</code></li>
<li><code>export PYTHONPATH="/usr/local/share/mongo-hadoop/spark/src/main/python"</code></li>
<li><code>export PATH=$PATH:$SPARK_HOME/bin</code></li>
</ul>
</li>
</ul>
<p>My Python program is basic</p>

<p>According to <a href="https://github.com/bartdag/py4j/blob/master/py4j-web/advanced_topics.rst#id19" rel="nofollow noreferrer">here</a></p>
<blockquote>
<p>This exception is raised when an exception occurs in the Java client
code. For example, if you try to pop an element from an empty stack.
The instance of the Java exception thrown is stored in the
java_exception member.</p>

<p>Looking at the source code for <code>pymongo_spark.py</code> and the line throwing the error, it says</p>
<blockquote>
<p>"Error while communicating with the JVM. Is the MongoDB Spark jar on

<p>So in response, I have tried to be sure the right jars are being passed, but I might be doing this all wrong, see below</p>
<pre><code>$SPARK_HOME/bin/spark-submit --jars /usr/local/share/spark-1.5.1-bin-hadoop2.6/lib/mongo-hadoop-spark-1.5.0-SNAPSHOT.jar,/usr/local/share/spark-1.5.1-bin-hadoop2.6/lib/mongo-java-driver-3.0.4.jar --driver-class-path /usr/local/share/spark-1.5.1-bin-hadoop2.6/lib/mongo-java-driver-3.0.4.jar,/usr/local/share/spark-1.5.1-bin-hadoop2.6/lib/mongo-hadoop-spark-1.5.0-SNAPSHOT.jar --master local[4] ~/sparkPythonExample/SparkPythonExample.py
</code></pre>
<p>I have imported <code>pymongo</code> to the same python program to verify that I can at least access MongoDB using that, and I can.</p>
<p>I know there are quite a few moving parts here so if I can provide any more useful information please let me know.</p>

Resetting a select box in Angular JS with a only one option
|
<p>I don't know if what I'm experiencing is a bug, but I can't seem to reset a select box in Angular JS 1.0.2 (also tested with 1.1.5) where there is only one option. This is for a iPad app wrapped in Phonegap. I've tested in the browser (Safari, Chrome) though and the issue is still there.</p>
<p>I'm working on an app that has many products that are in different categories and sub-categories. When you select a category the route changes and normally resets the select box. And it looks like so:</p>
<p><img src="https://i.stack.imgur.com/0Orqi.png" alt="enter image description here"></p>
<p>However, if you were to choose an option and then decide to choose another sub-category when there is only one option in the select box for a sub-category (when the user clicks one of the images where it says "Other Products") the select box doesn't properly reset. The userthen can't advance from this point to the next select box. It looks like this:</p>
<p><img src="https://i.stack.imgur.com/uQ7ig.png" alt="enter image description here"></p>
<p>I've almost gotten it to work by coming up with this function from the various resources out there, but seems Angular is being quirky. It looks like this with where I've got so far:</p>
<p><img src="https://i.stack.imgur.com/KywIf.png" alt="enter image description here"></p>
<p>The problem is that I want the blank space to be before the option, not after. Then the user has to click the second blank option and then click the option again in order to activate the second select box. </p>
<p>Here is the JS:</p>
<pre><code> $scope.reset = function() {
$scope.variants.selectedIndex = 0;
};
</code></pre>
<p>Here is the JSON. Notice that these set of variants have the same size:</p>
<pre><code>1: {
name: 'Super Awesome Product',
description: 'Cool description',
category: 'viewers',
variants: {
1: {
color: 'Gold',
size: '55-62mm',
productCode: 'FCSTVG',
price: 0,
image: [path + 'FCSTVG-T.png', path + 'FCSTVG.png']
},
2: {
color: 'Silver',
size: '55-62mm',
productCode: 'FCSTVS',
price: 0,
image: [path + 'FCSTVS-t.png', path + 'FCSTVS.png']
}
}
}
};
</code></pre>
<p>And the HTML for the select box:</p>
<pre><code><select ng-model="selectedVariant" ng-show="variants != null">
<option ng-repeat="size in variants" value="{{size}}">
{{size[0].size}}
</option>
</select>
</code></pre>
<p>And the HTML for the where my <code>reset()</code> is clicked. Like I had said, these are the "Other Products" of images below: </p>
<pre><code><div class="other-products">
<h2>Other products</h2>
<div class="slide-container">
<ul ng-show="products != null" style="width: {{products.length * 112}}px">
<li ng-repeat="p in products" ng-show="findDefaultImage(p) != null">
<a href="#" eat-click ng-click="selectProduct(p.id);reset()">
<img ng-src="{{findDefaultImage(p)}}" alt="" />
</a>
</li>
</ul>
</div>
</div>
</code></pre>
<p>I've tried everything, like adding different values to this line <code>$scope.variants.selectedIndex = 0;</code> like -1 or 1. </p>
<p>Any help would be appreciated!</p>
<p>UPDATE: I solved the issue by hardcoding it. Didn't know why I didn't do it before, but I'm still endorsing @Shawn Balestracci answer as it answers the question. </p>
<p>Angular has a tendency to empty out the "index 0" of a select box pushing all of the options back 1 in the select box, but in actuality the option that a user selects is actually the next option in the drop down list. I don't know if this is a bug or a feature. </p>
<p>Here's how I hardcoded the HTML: </p>
<pre><code><select ng-model="selectedVariant" required="required" ng-show="variants != null">
<option style="display:none" value="">PICK ONE:</option>
<option ng-repeat="size in variants" value="{{size}}">
{{size[0].size}}
</option>
</select>
</code></pre>
<p>This stops Angular from pushing back the options in the drop down.</p>

# Configuration and logfile names: If the filenames you specify for many

# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"

# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
# will be interpreted as '/logs/access_log'.
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default. It is recommended that you always supply

TypeError: "ctx.cart is undefined"
|
<p>I'm working on pizza ordering app, and currently I'm trying to implement Cart.</p>
<p>I have a cart for every user, and each cart contains following details: cart.ts</p>
<pre><code>import { CartItem } from './cartitem';
export class Cart {
id: string;
user: string;
cartitems: CartItem[];
grand_total: number;
}
</code></pre>
<p>User can add items from the menu, which will become my cart items: cartitem.ts</p>
<pre><code>import { Topping } from './topping';
export class CartItem {
id: string;
name: string;
baseprice: number;
toppings: Topping[];
extraprice: number;
quantity= 1;
total: number;
}
</code></pre>
<p>So on adding an item to the cart, I'm making a PUT request on the API endpoint on the user cart, to put the cart item, and in response, I'm returning the cart contents from there.</p>
<p>Here's how my cart.component.ts looks:</p>
<pre><code>import { Component, OnInit, ViewChild, Inject, Injector } from '@angular/core';
import { CartItem } from '../shared/cartitem';
import { ActivatedRoute } from '@angular/router';
import { CartService } from '../services/cart.service';
import { map, catchError } from 'rxjs/operators';
import { Cart } from '../shared/cart';
@Component({
selector: 'app-cart',
templateUrl: './cart.component.html',
styleUrls: ['./cart.component.scss']
})
export class CartComponent implements OnInit {
cart: Cart;
// cartitems: CartItem[];
constructor(
private route: ActivatedRoute,
private cartService: CartService,
@Inject('BaseURL')public BaseURL) { }
ngOnInit(): void {
this.updateCart();
}
updateCart() {
this.cartService.mysubject.subscribe((value) => {
console.log(value);
this.cartService.getItems().subscribe(response => {
console.log("Response in cart comp:", response);
let cartContent = new Cart();
cartContent.cartitems = response['cartitems'];
cartContent.id = response['id'];
cartContent.grand_total = response['grand_total'];
cartContent.user = response['user'];
this.cart = cartContent;
console.log("Cart is:", this.cart);
});
});
}
}
</code></pre>
<p>Now issue here is that I'm not able to bind the data on cart.component.html side with 'cart', it generates this error- ERROR TypeError: "ctx.cart is undefined".</p>
<p>I'm clueless on how to fix this. </p>
<p><strong>Edit</strong>:
Here is the cart.component.html:</p>
<pre><code><h2>Cart</h2>
<div>{{cart.user}}</div>
<mat-list dense>
<mat-list-item *ngFor="let cartitem of cart.cartitems">
<h2 matLine>Item: {{cartitem.name}}</h2>
<p matLine>Base Price: ${{cartitem.baseprice}}</p>
<p matLine [hidden]="cartitem.toppings == []">Extra Toppings:
<mat-list matLine>
<mat-list-item matLine *ngFor="let topping of cartitem.toppings">
<h4 matLine>{{topping.name}} : + ${{topping.rate}}</h4>
</mat-list-item>
</mat-list>
</p>
<button mat-mini-fab color="primary"><i class="fa fa-minus-circle"></i></button><div></div><button mat-mini-fab color="primary"><i class="fa fa-plus-circle"></i></button>
</mat-list-item>
</mat-list>
<div [hidden]="!cart.cartitems"><h2>Subtotal: ${{cart.grand_total}}</h2></div>
<div [hidden]="cart.cartitems">
<p> Your Cart is Empty!</p>
</div>
</code></pre>

Can't build and run an android test project created using "ant create test-project" when tested project has jars in libs directory
|
<p>I have a module that builds an app called MyApp. I have another that builds some testcases for that app, called MyAppTests. They both build their own APKs, and they both work fine from within my IDE. I'd like to build them using ant so that I can take advantage of continuous integration.</p>
<p>Building the app module works fine. I'm having difficulty getting the Test module to compile and run.</p>
<p>Using Christopher's tip from a <a href="https://stackoverflow.com/questions/2466437/how-to-build-an-android-test-app-with-a-dependency-on-another-app-using-ant">previous question</a>, I used <code>android create test-project -p MyAppTests -m ../MyApp -n MyAppTests</code> to create the necessary build files to build and run my test project. This seems to work great (once I remove an unnecessary test case that it constructed for me and revert my AndroidManifest.xml to the one I was using before it got replaced by <code>android create</code>), but I have two problems.</p>
<p>The first problem: The project doesn't compile because it's missing libraries.</p>
<pre><code>$ ant run-tests

<p>That's not a hard problem to solve. I'm not sure it's the right thing to do, but I copied the missing libraries (roboguice and gson) from the MyApp/libs directory to the MyAppTests/libs directory and everything seems to compile fine.</p>
<p>But that leads to the second problem, which I'm currently stuck on. The tests compile fine but they won't run:</p>

Android AudioRecord won't initialize
|
<p>I'm trying to implement an app that listens to microphone input (specifically, breathing), and presents data based on it. I'm using the Android class AudioRecord, and when trying to instantiate AudioRecord I get three errors.</p>
<pre><code>AudioRecord: AudioFlinger could not create record track, status: -1
AudioRecord-JNI: Error creating AudioRecord instance: initialization check failed with status -1.
android.media.AudioRecord: Error code -20 when initializing native AudioRecord object.
</code></pre>
<p>I found this excellent thread: <a href="https://stackoverflow.com/questions/4843739/audiorecord-object-not-initializing">AudioRecord object not initializing</a></p>
<p>I have borrowed the code from the accepted answer that tries all sample rates, audio formats and channel configurations to try to solve the problem, but it didn't help, I get the above errors for all settings. I have also added a call to AudioRecord.release() on several places according to one of the answers in the thread but it made no difference.</p>
<p>This is my code:</p>
<pre><code>import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;
import android.util.Log;
public class SoundMeter {
private AudioRecord ar = null;
private int minSize;
private static int[] mSampleRates = new int[] { 8000, 11025, 22050, 32000, 44100 };
public boolean start() {
ar = findAudioRecord();
if(ar != null){
ar.startRecording();
return true;
}
else{
Log.e("SoundMeter", "ERROR, could not create audio recorder");
return false;
}
}
public void stop() {
if (ar != null) {
ar.stop();
ar.release();
}
}
public double getAmplitude() {
short[] buffer = new short[minSize];
ar.read(buffer, 0, minSize);
int max = 0;
for (short s : buffer)
{
if (Math.abs(s) > max)
{
max = Math.abs(s);
}
}
return max;
}
public AudioRecord findAudioRecord() {
for (int rate : mSampleRates) {
for (short audioFormat : new short[] { AudioFormat.ENCODING_PCM_8BIT, AudioFormat.ENCODING_PCM_16BIT, AudioFormat.ENCODING_PCM_FLOAT }) {
for (short channelConfig : new short[] { AudioFormat.CHANNEL_IN_MONO, AudioFormat.CHANNEL_IN_STEREO }) {
try {
Log.d("SoundMeter", "Attempting rate " + rate + "Hz, bits: " + audioFormat + ", channel: " + channelConfig);
int bufferSize = AudioRecord.getMinBufferSize(rate, channelConfig, audioFormat);
if (bufferSize != AudioRecord.ERROR_BAD_VALUE) {
// check if we can instantiate and have a success
Log.d("SoundMeter", "Found a supported bufferSize, attempting to instantiate");
AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.DEFAULT, rate, channelConfig, audioFormat, bufferSize);
if (recorder.getState() == AudioRecord.STATE_INITIALIZED){
minSize = bufferSize;
return recorder;
}
else
recorder.release();
}
} catch (Exception e) {
Log.e("SoundMeter", rate + " Exception, keep trying.", e);
}
}
}
}
return null;
}
</code></pre>
<p>}</p>
<p>I have also added the </p>
<pre><code><uses-permission android:name="android.permission.RECORD_AUDIO"/>
</code></pre>
<p>tag to my manifest file, as a child to the manifest tag and a sibling to the application tag according to one of the other answers in the thread mentioned above. I have rebuilt the project after adding this tag.</p>
<p>These are the solutions I find when googling the problem, but they unfortunately don't seem to do it for me.
I am debugging on my Nexus 5 phone (not an emulator). These errors appear upon calling the contructor of AudioRecord. I have rebooted my phone several times to try to release the microphone, to no avail. The project is based on Android 4.4, and my phone is currently running Android 6.0.1.</p>
<p>Would highly appreciate some tips on what else I can try, what I could have missed. Thank you!</p>

How to configure jax-rs web service web.xml properly
|
<p>I am trying to implement a jax-rs web service using jersey framework. I have written the web service but I don't fully understand what the web.xml tags mean so I don't know if I have configured it correct but when I try to access the service I get an error. Here is the web service:</p>
<pre><code>package org.LMS.Controller;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path ("/test")
public class Test {
private String name = "Worked";
@GET
@Produces (MediaType.APPLICATION_XHTML_XML)
public String getTest ()
{
return name;
}
}
</code></pre>
<p>my web.xml is:</p>
<pre><code> <!-- Test web service mapping -->
<servlet>
<display-name>Test</display-name>
<servlet-name>Test</servlet-name>
<servlet-class>org.LMS.Controller</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>/test</url-pattern>

<!--end Test web service mapping -->

<p>and this is the error I'm getting when I try to access my application:

Exception of type 'System.OutOfMemoryException' was thrown
|
<p>I have suddenly been getting the memory exception errors for two programs running on different machines and even though it seems there is enough memory, it still shows up. I am creating multiple threads in the program so not sure if this appropriate for this forum but could it be something else related to visual studio or is it definitely memory issue.The one program runs on my desktop using visual studio 2008 with 2 gb ram. The other is running on a windows 2003 server with 4 GB ram using visual basic 2008 express.
Now the module takes a large xml file that is read into a string and then split and stored in a string array. Now the number of chunks can be upto 10000. Now I know this is big, but I have been running this for over a month now and never had the issue. The only other possible related issue I noticed was that I was running out of space on my harddrive but that was quickly solved with a cleanup. Oh yes the processor for my machine is a duo core set at 2.13 GHZ.
It is a console program that makes multiple webrequests but the memory problem arises in one specific module only as I explained above.</p>

Processing huge data with spring batch partitioning
|
<p>I am implementing spring batch job for processing millions of records in a DB table using partition approach as follows -</p>
<ol>
<li><p>Fetch a unique partitioning codes from table in a partitioner and set the same in execution context.</p></li>
<li><p>Create a chunk step with reader,processor and writer to process records based on particular partition code.</p></li>
</ol>
<p>Is this approach is proper or is there any better approach for situation like this? As some partition codes can have more number of records than others,so those with more records might take more time to process than the ones with less records.</p>
<p>Is it possible to create partition/thread to process like thread1 process 1-1000,thread2 process 1001-2000 etc ?</p>
<p>How do I control number of threads getting created as partition codes can be around 100, I would like to create only 20 thread and process in 5 iteration?</p>
<p>What happens if one partition fails, will all processing stop and reverted back?</p>
<p>Following are configurations -</p>

How to decode json into structs
|
<p>I'm trying to decode some json in Go but some fields don't get decoded.
See the code running in browser <a href="http://play.golang.org/p/ZunE4_lKKv" rel="nofollow noreferrer">here</a>: </p>
<p>What am I doing wrong?</p>
<p>I need only the MX records so I didn't define the other fields. As I understand from the godoc you don't need to define the fields you don't use/need.</p>
<pre><code>// You can edit this code!

Babel unexpected token import when running mocha tests
|
<p>The solutions offered in other related questions, such as including the proper presets (es2015) in .babelrc, are already implemented in my project.</p>
<p>I have two projects (lets call them A and B) which both use ES6 module syntax. In Project A, I'm importing Project B which is installed via npm and lives in the node_modules folder. When I run my test suite for Project A, I'm getting the error: </p>
<blockquote>
<p>SyntaxError: Unexpected token import</p>
</blockquote>
<p>Which is preceded by this alleged erroneous line of code from Project B:</p>
<blockquote>
<p>(function (exports, require, module, __filename, __dirname) { import
createBrowserHistory from 'history/lib/createBrowserHistory';</p>
</blockquote>
<p>The iife appears to be something npm or possibly babel related since my source file only contains "import createBrowserHistory from 'history/lib/createBrowserHistory'; The unit tests in Project B's test suite runs fine, and if I remove Project B as a dependency from Project A, my test suite then (still using es6 imports for internal project modules) works just fine.</p>
<p>Full Stack Trace:</p>

org.hibernate.HibernateException: /hibernate.cfg.xml not found
|
<p>I'm trying to use hibernate with spring 3 mvc but at the moment I get this exception thrown. I think I need to define my <code>hibernate.cfg.xml</code> somewhere, but not sure where?</p>
<p>I basically followed this example here <a href="http://www.nabeelalimemon.com/blog/2010/05/spring-3-integrated-with-hibernate-part-a/">http://www.nabeelalimemon.com/blog/2010/05/spring-3-integrated-with-hibernate-part-a/</a> And in particularly saw this line of code there that suppose to "magically" find my hibernate.cfg file using this:</p>
<pre><code>return new Configuration().configure().buildSessionFactory();
</code></pre>
<p>I'm guessing that is not correct? i currently have my hibernate.cfg file inside <code>src/com/jr/hibernate/</code></p>
<p>below is my cfg file:</p>
<pre><code><?xml version='1.0' encoding='utf-8'?>

catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);

<p>And here is the controller that originally does some hibernate stuff:</p>

} else{
// if everthings ok, add user details to database
logger.info("if everthings ok, add user details to database");
userDb = new UserDb();
userDb.addNewItem(user);
// display success and auto log the user to the system.
return "account/main";

<p>Cheers in advance. I also have all my table hibvernate xml mappings in the same location as my hibernate.cfg.xml file</p>

Angular 2/4 how to add multiple headers to http post
|
<p>I've problem with adding additonal headers to html post.
with curl works very well like with postman.
I can't add Authorization header to post request.</p>
<p>my problem is similar to <a href="https://stackoverflow.com/questions/34464108/angular2-set-headers-for-every-request">https://stackoverflow.com/questions/39408413/angular2-http-post-how-to-send-authorization-header</a> </p>
<p>my code:</p>
<pre><code> getToken(){
let headers = new Headers;
headers.append('Authorization', 'Basic ' + btoa(Spotify.clientId + ':' + Spotify.clientSecret));
headers.append('Content-Type', 'application/x-www-form-urlencoded');
let options = new RequestOptions({ headers: headers });
let params = new URLSearchParams();
params.append('grant_type', 'client_credentials');
console.log(
this.http.post(Spotify.tokenUrl, params.toString(), options).subscribe()
)
}
</code></pre>
<p>Now, when I try to get this none of those two headers aren't added</p>
<pre><code>OPTIONS /api/token HTTP/1.1
Host: accounts.spotify.com
Connection: keep-alive
Access-Control-Request-Method: POST
Origin: http://172.21.7.171:4200

Accept-Encoding: gzip, deflate, br
Accept-Language: pl,en;q=0.8,en-US;q=0.6
</code></pre>
<p>But when I comment Authorization header, Content-Type is added and a get invalid_client with error 400</p>
<pre><code>POST /api/token HTTP/1.1

</code></pre>
<p>But when I comment Content-Type header and append Authorization I have the same issue like first time - no added header :/</p>
<p>I'have angular 4.2 - installed and upgraded from ng cli</p>
<p>How to add additonal headers to POST? in Postman this work perfect</p>
<p><a href="https://i.stack.imgur.com/0FlhS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0FlhS.png" alt="enter image description here"></a></p>
<p>===== Edited ====
Thanks for reply, but both solutions don't work </p>
<pre><code>getToken(){
let options = new RequestOptions();
options.headers = new Headers();
options.headers.append('Authorization', Spotify.token);
options.headers.append('Content-Type', 'application/x-www-form-urlencoded')
let params = new URLSearchParams();
params.append('grant_type', 'client_credentials');
console.log(
this.http.post(Spotify.tokenUrl, params.toString(), options).subscribe()
)
}
</code></pre>
<p>now if I comment 'Authorization' Content-Type is added to Request with AUthorization i none header isn't added and body isn't sent too</p>
<p>========= edited =========</p>
<p>According to this topic <a href="https://stackoverflow.com/questions/34464108/angular2-set-headers-for-every-request">Angular2 - set headers for every request</a> I've created default-request-options.service.ts </p>
<pre><code>import { Injectable } from '@angular/core';
import { BaseRequestOptions, RequestOptions, Headers } from '@angular/http';
@Injectable()
export class DefaultRequestOptions extends BaseRequestOptions {
private superHeaders: Headers;
get headers() {
// Set the default 'Content-Type' header
this.superHeaders.set('Content-Type', 'application/json');
const token = localStorage.getItem('authToken');
if(token) {
this.superHeaders.set('Authorization', `Bearer ${token}`);
} else {
this.superHeaders.delete('Authorization');
}
return this.superHeaders;
}
set headers(headers: Headers) {
this.superHeaders = headers;
}
constructor() {
super();
}
}
export const requestOptionsProvider = { provide: RequestOptions, useClass: DefaultRequestOptions };
</code></pre>
<p>in app.module.ts</p>
<pre><code>import { requestOptionsProvider, DefaultRequestOptions } from './default-request-options.service'
...
providers: [
requestOptionsProvider
],
</code></pre>
<p>now in my service</p>
<pre><code>import { DefaultRequestOptions } from '../default-request-options.service';
getToken(){
let params = new URLSearchParams();
params.append('grant_type', 'client_credentials');
let options = new DefaultRequestOptions();
//options.headers = new Headers();
// options.headers.append('Authorization', Spotify.basicCode);
//options.headers.append('Content-Type', 'application/x-www-form-urlencoded');
// options.body = params.toString();
// options.method = 'post';
console.log(
this.http.post(Spotify.tokenUrl, params.toString(), options).subscribe()
)
}
</code></pre>
<p>And I have errors still :/ Headers aren't added :/</p>
<p>I've made some investigations, tests. When I try send only 'Content-type=application/x-www-form-urlencoded' I get reply with error 'bad client' because I don't send Authorization. Problem occours when I try to add another header with Authorization.</p>
<p>I've made similar with GET method and I can add only 'Authorization' header, none other. If I added for example "X-Authorization" header that GET method is changed to OPTIONS method like in POST :/</p>
<p>In console I get error:</p>
<blockquote>
<p>XMLHttpRequest cannot load <a href="https://accounts.spotify.com/api/token" rel="nofollow noreferrer">https://accounts.spotify.com/api/token</a>.
Response to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin '<a href="http://localhost:4200" rel="nofollow noreferrer">http://localhost:4200</a>' is therefore not allowed
access.</p>
</blockquote>
<p>Is there any way to provide more in one header in http post request? </p>
<p>I added only Content-Type header with body. I got reply with 400 code because my request was without Authorization header. In firefox I edited this reqest by adding Authorization to headers and I got what I wanted code 200 with token :)
So the problem is with Angular not with browser.</p>
<p>==== EDITED ====
Spotify says that i shouldn't use clientid and client+secret. i should use this:</p>
<pre><code> let options = new RequestOptions()
options.headers = new Headers();
options.params = new URLSearchParams();
options.params.append('client_id', Spotify.clientId);
options.params.append('redirect_uri', 'http://localhost:4200/callback');
options.params.append('scope', 'user-read-private user-read-email');
options.params.append('response_type', 'token');
options.params.append('state', '789935');
this.http.get('https://accounts.spotify.com/authorize', options )
.subscribe(
res=> {
console.log('res',res)
}
)
</code></pre>
<p>now i get 200 but callback isnt displayed. in console i have:</p>
<pre><code>XMLHttpRequest cannot load https://accounts.spotify.com/authorize?client_id=2100FakeClientId45688548d5a2b9…scope=user-read-private%20user-read-email&response_type=token&state=789935. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.

How to draw an arrow on every polyline segment on Google Maps V3
|
<p>I was looking for a solution to this problem on stackoverflow but since I couldn't find the accurate solution I ended up solving it myself and post it here, hope it help.</p>
<p>Google Maps provides you the Polyline feature, which based on a list of coordinates can draw a series of lines joining all of them.</p>
<p>You can draw a polyline with a single arrow with the following code:</p>
<pre><code> var allCoordinates = [
new google.maps.LatLng(26.291, 148.027),
new google.maps.LatLng(26.291, 150.027),
new google.maps.LatLng(22.291, 153.027),
new google.maps.LatLng(18.291, 153.027)
];
var polyline = new google.maps.Polyline({
path: allCoordinates,
strokeColor: color,
strokeOpacity: 1.0,
strokeWeight: 2,
geodesic: true,
icons: [{
icon: {path: google.maps.SymbolPath.FORWARD_CLOSED_ARROW},
offset: '100%'
}]
});
</code></pre>
<p>The problem here is that the arrow will be only drawn in the last segment as shown in the next picture, but sometimes the route could be not so straightforward and we need to add an arrow on every segment.</p>
<p>The attribute 'repeat' inside the icon definition could be another option but allows only to define a measure in pixels and that definelty won't match with every change of direction on the polyline.</p>
<p><img src="https://i.stack.imgur.com/c5a3x.png" alt="PICTURE1"></p>
<p>So, one way I found to achive this was to make several polylines, one per segment allowing in that case the arrow to be drawn on each one. This is the code:</p>
<pre><code> var allCoordinates = [
new google.maps.LatLng(26.291, 148.027),
new google.maps.LatLng(26.291, 150.027),
new google.maps.LatLng(22.291, 153.027),
new google.maps.LatLng(18.291, 153.027)
];
for (var i = 0, n = allCoordinates.length; i < n; i++) {
var coordinates = new Array();
for (var j = i; j < i+2 && j < n; j++) {
coordinates[j-i] = allCoordinates[j];
}
var polyline = new google.maps.Polyline({
path: coordinates,
strokeColor: color,
strokeOpacity: 1.0,
strokeWeight: 2,
geodesic: true,
icons: [{
icon: {path: google.maps.SymbolPath.FORWARD_CLOSED_ARROW},
offset: '100%'
}]
});
polyline.setMap(map);
polylines.push(polyline);
}
</code></pre>
<p>And this is the Picture:</p>
<p><img src="https://i.stack.imgur.com/zfzWF.png" alt="PICTURE2"></p>
<p>I hope this works for anyone who is looking for something like this!</p>

How do I debug GlassFish 3 using Eclipse Helios?
|
<p>I am using the GlassFish 3 server adapter with Eclipse Helios 3.6. I can start the server using the <em>Servers</em> view in Eclipse, and things run just fine - but I am not able to debug my code.</p>
<p>After using the GF Admin Console to enable debugging (<em>Configuration → JVM Settings → Debug</em>, then restart the server), clicking <em>Debug</em> (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>D</kbd>) gives me an error window:</p>
<p><img src="https://i.stack.imgur.com/YdK1k.png" alt="error window"></p>
<p>I'm guessing this is because Eclipse can't connect to the JVM's debug port (9009 by default).</p>
<p>What is the proper way to set up GlassFish 3 debugging in Helios?</p>
<hr>
<h2>Edit</h2>
<p>Re: @The Elite Gentleman, there aren't any errors that show up in the console. Here's an example:</p>

</code></pre>
<h2>Edit 2</h2>
<p>I was able to successfully debug in Eclipse by starting GlassFish externally, e.g.</p>
<pre><code>> asadmin start-domain myDomain
</code></pre>
<p>and then creating a custom Debug Configuration:</p>
<p><img src="https://imgur.com/jJlg7.png" alt="bloody hell >:("></p>
<p><em>So why can't the GlassFish server adapter do this?</em></p>
<h2>Edit 3 - Problem solved</h2>
<p>Originally, I had added GlassFish support through the <a href="http://download.java.net/glassfish/eclipse/helios" rel="noreferrer">GlassFish Tools plugin</a>. I uninstalled the plugin, and added GlassFish support using <em>Servers → New → Server → Download additional server adapters</em>. Now I can debug. <strong>Woohoo!</strong></p>

Automatically solve Android build Error:Frame pixels must be either solid or transparent (not intermediate alphas). - Found at pixel #4 along top edge
|
<p>Android Studio (using SDK 19, 21 or 22) shows an error that Eclipse ADT (using SDK 19) does not:</p>
<blockquote>
<p>Error:9-patch image D:\Workspaces....\res\drawable-hdpi\btn_bg_common_press.9.png malformed.
Error:Frame pixels must be either solid or transparent (not intermediate alphas). - Found at pixel #4 along top edge.</p>
</blockquote>
<p>Or <a href="https://stackoverflow.com/questions/28940476/android-gradle-build-errorticks-in-transparent-frame-must-be-black-or-red">another error</a>:</p>
<blockquote>
<p>Error:Ticks in transparent frame must be black or red.</p>
</blockquote>
<p>both within <code>aapt</code></p>
<blockquote>
<p>Error:Error: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'E:\Android\sdk-Android-Studio\build-tools\19.1.0\aapt.exe'' finished with non-zero exit value 42</p>
</blockquote>
<p><img src="https://i.stack.imgur.com/euMip.png" alt="btn_bg_common_press.9.png"></p>
<p>Example of file is above, but there are 20+ such files that worked well.</p>
<p><strong>How do I make Android Studio or Gradle skip this error and not fail without having to modify those files one-by-one?</strong></p>
<p>If it is not possible with Gradle, what command-line tool could I use to replace all transparent pixel with non-transparent?</p>

<p>i guess this is a xml parsing problem, but I just cannot see where it is. I read some articles about this topic and nothing helped:</p>

Mongoose Populate returning null or undefined
|
<p>I'm sorry if this is a n00b question, I've been searching Google & Stack for hours now and I've got to ask!</p>
<p>I have two schemas, User and Story, shown below. I am trying to reference the User for a Story using the Ref option to Populate in a Query - I've using mySQL before and so wanted to try to replicate a JOIN statement.
Whenever I try to use populate I just get the objectID returned, or null (shown below).</p>
<p><strong>Edited 12 Nov to fix hardcoded IDs & add console data</strong></p>
<p><strong>story-schema.js</strong></p>
<pre><code>var mongoose = require('mongoose'),
Schema = mongoose.Schema,
User = require('./user-schema');
var StorySchema = new Schema({
title: { type: String, required: true },
author_id: { type: Schema.Types.ObjectId, ref: 'User' },
summary: { type: String, required: true },
rating: { type: String, required: true }
});
module.exports = mongoose.model('Story', StorySchema, 'stories');
</code></pre>
<p><strong>user-schema.js</strong></p>
<pre><code>var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var UserSchema = new Schema({
username: { type: String, required: true, index: { unique: true } },
is_admin: {type: Boolean, required: true, default: false }
});
</code></pre>
<p><strong>save - id hardcoded for example</strong></p>
<pre><code>app.post('/api/new_story', function(req, res){
var story;
story = new Story({
title: req.body.title,
author_id: mongoose.Types.ObjectId(req.params._id),
/* ex of req.params._id: 527fc8ff241cdb8c09000003*/
summary: req.body.summary,
rating: req.body.rating
});
story.save(function(err) {
if (!err) {
return console.log("created");
} else {
return console.log(err);
}
});
return res.send(story);
});
</code></pre>
<p><strong>example user when logged in terminal</strong></p>
<pre><code>{
"__v" : 0,
"_id" : ObjectId("527fc8ff241cdb8c09000003"),
"is_admin" : false,
"username" : "ted"
}
</code></pre>
<p><strong>example story when logged in terminal</strong></p>
<pre><code>{
"title" : "Test Story",
"author_id" : "527fc8ff241cdb8c09000003",
"summary" : "Test summary",
"rating" : "12",
"_id" : ObjectId("52827692496c16070b000002"),
"__v" : 0
}
</code></pre>
<p><strong>queries</strong></p>
<pre><code>//other mongoose/app includes above
User = require('./config/schema/user-model'),
Story = require('./config/schema/story-model');
// data.author_id = 527fc8ff241cdb8c09000003
// data.author_id.username = undefined
app.get('/api/query/:id', function (req, res){
return Story.findOne({_id:req.params.id})
.populate( { path: 'User' } )
.exec(function (err, data) {
console.log(data.author_id);
console.log(data.author_id.username);
if (err) {
return res.json({error:err})
}
})
});
// data.author_id = null
app.get('/api/query2/:id', function (req, res){
return Story.findOne({_id:req.params.id}) //_id hardcoded for example
.populate( 'author_id' )
.exec(function (err, data) {
console.log(data.author_id);
if (err) {
return res.json({error:err})
}
})
});
</code></pre>
<p>In the first query I get the author_id I already saved back, which kind of makes sense as that's what I saved - but I access the username.</p>
<p>In the second query I can't even access the author_id I've already saved.</p>
<p><strong>Edit:</strong> I can run a normal GET query fine without the 'populate'</p>
<p><strong>What I'd like to happen</strong></p>
<p>Is to be able to access the author information from the story - this is more like a proof of concept.
Eventually I'd like to reference the Story _id in the the User model as there can be many Stories to a User, but only one User per Story but thought I'd start here first.</p>

package 'stringi' does not work after updating to R3.2.1

<p>I saw a <a href="https://stackoverflow.com/questions/30983013/error-in-loadnamespacei-clib-loc-libpaths-versioncheck-vii-the">version of this question</a> posted, but still did not see the answer. I am trying to use ggplot2 but get the following errors (everything worked this morning using R3.0.2 'frisbee sailing' with RStudio version 0.98.1102. </p>
<p>I updated both R and Rstudio and now get the following:</p>

<p>Any suggestions on how to get 'stringi' to install? I'm not real familiar with the error output. Should I just try to go back to older versions of R and Rstudio? Ultimately I'm worried that this will be the tip of the iceberg in terms of packages now not working with the updated R</p>

iOS Swift uploading PDF file with Alamofire (Multipart)
|
<p>I'm currently developing an application using iOS 10 and Swift 3 and Alamofire 4</p>
<p>The purpose of this application is to upload a PDF file generated previously.</p>
<p>The PDF generation is working perfectly and the file is created.</p>
<p>However the upload doesn’t work…
I received a success response but the file is not uploaded.</p>
<p><strong>My server response</strong></p>
<pre><code>Multi part Content-Type => multipart/form-data; boundary=alamofire.boundary.56958be35bdb49cb
Multi part Content-Length => 293107
Multi part Content-Boundary => alamofire.boundary.56958be35bdb49cb
responses
SUCCESS: {
uploadedFiles = (
{
details = " Key=Content-Disposition - values=[form-data; name=\"pdfDocuments\"] length=8";
storedFileName = "/var/www/pdf/17/009/22/TMP104150531290406.tmp";
type = PDF;
uploadedDate = 1483999296701;
uploadedFileName = UnknownFile;
}
);
}
end responses
</code></pre>
<p>I’m using multi-part to upload my file as Data as you can see <a href="https://github.com/Alamofire/Alamofire#uploading-data-to-a-server" rel="noreferrer">here</a> </p>
<p>File url is fine. </p>
<p>I have searched on SO but didn’t find any solution working… </p>
<p>Here you can see my <strong>Controller</strong></p>
<pre><code>Alamofire.upload(
multipartFormData: {
multipartFormData in
if let urlString = urlBase2 {
let pdfData = try! Data(contentsOf: urlString.asURL())
var data : Data = pdfData
multipartFormData.append(data as Data, withName:"test.pdf", mimeType:"application/pdf")
for (key, value) in body {
multipartFormData.append(((value as? String)?.data(using: .utf8))!, withName: key)
}
print("Multi part Content -Type")
print(multipartFormData.contentType)
print("Multi part FIN ")
print("Multi part Content-Length")
print(multipartFormData.contentLength)
print("Multi part Content-Boundary")
print(multipartFormData.boundary)
}

<p>I think this is because my port is used. My port 8080 is used so I try the port 8181
I have no application on the port 8181</p>
<p>in the tomcat server.xml I set the port to 8181 but the problem persist</p>
<p>I find this post:</p>
<p><a href="https://stackoverflow.com/questions/646649/alternate-port-for-tomcat-not-8080-when-starting-with-maven">Alternate port for Tomcat (not 8080) when starting with Maven?</a></p>
<p>But I have the same problem after launching mvn -Dmaven.tomcat.port=8181 tomcat:run-war</p>

Multi-Tenancy with Spring + Hibernate: "SessionFactory configured for multi-tenancy, but no tenant identifier specified"

<p>In a Spring 3 application, I'm trying to implement multi-tenancy via Hibernate 4's native <a href="http://docs.jboss.org/hibernate/orm/4.1/devguide/en-US/html/ch16.html#d5e4661">MultiTenantConnectionProvider</a> and <a href="http://docs.jboss.org/hibernate/orm/4.1/devguide/en-US/html/ch16.html#d5e4686">CurrentTenantIdentifierResolver</a>.

<p>Below is the relevant code. In the <code>MultiTenantConnectionProvider</code> I've simply wrote some dumb code for now that just returns a new connection every time, and the <code>CurrentTenantIdentifierResolver</code> always returns the same ID at this point. Obviously this logic was to be implemented after I managed to get the connections to instantiate.</p>

<p>Can anybody see anything specifically wrong? This throws an exception as soon as a transaction is opened.

<p>After further investigation, I found out that the root cause is the following: hibernate uses the <strong>SequenceInformation</strong> interface for the sequences metadata manipulations</p>
<pre class="lang-java prettyprint-override"><code>public interface SequenceInformation {
Long getMinValue();
Long getMaxValue();
Long getIncrementValue();
...
}
</code></pre>
<p>However, my app uses the sequences like the following:</p>
<pre><code>SQL> CREATE SEQUENCE SEQ_TEST START WITH 1 INCREMENT BY 1 NOCYCLE;
SQL> select MIN_VALUE, MAX_VALUE, INCREMENT_BY
from USER_SEQUENCES
where SEQUENCE_NAME = 'SEQ_TEST';
MIN_VALUE MAX_VALUE INCREMENT_BY
--------- ---------------------------- ------------
1 9999999999999999999999999999 1
</code></pre>
<p>The <strong>Long.MAX_VALUE</strong> is equal to 9223372036854775807, therefore I got the numeric overflow exception.</p>
<p>So, my questions:</p>
<ul>
<li>Is it a bug in hibernate?</li>
<li>What will be the best way to solve it?</li>
</ul>
<p>Now I see the following ways:</p>
<ol>
<li>Fix the sequences declarations.
It can be quite problematic in my case. And, by the way, it looks strange that hibernate tries to read metadata about all sequences, not only about used in my application.</li>
<li>Create custom dialect that will extend Oracle12cDialect and override getQuerySequencesString() and/or getSequenceInformationExtractor().</li>
</ol>
<pre class="lang-java prettyprint-override"><code>public class Oracle8iDialect extends Dialect {
...
public String getQuerySequencesString() {
return "select * from all_sequences";
}
public SequenceInformationExtractor getSequenceInformationExtractor() {
return SequenceInformationExtractorOracleDatabaseImpl.INSTANCE;
}
}
</code></pre>
<p>I can switch <strong>SequenceInformationExtractor</strong> to <strong>SequenceInformationExtractorNoOpImpl.INSTANCE</strong> and hibernate will not read sequences metadata. What impact will this decision have? Hibernate tries to validate <strong>allocationSize</strong> of @SequenceGenerator() by INCREMENT_BY. Are there other reasons?</p>
<p>Any suggestions will be appreciated.</p>

C++/Win32: How to wait for a pending delete to complete

<li>Explanation for why OpenFile doesn't pass through "DELETE PENDING": <a href="https://stackoverflow.com/questions/3764072/c-win32-how-to-wait-for-a-pending-delete-to-complete/3776438#3776438">Benjamin's answer</a></li>
</ul>
<p><strong>The Problem:</strong></p>
<p>Our software is in large part an interpreter engine for a proprietary scripting language. That scripting language has the ability to create a file, process it, and then delete the file. These are all separate operations, and no file handles are kept open in between these operations.</p>
<p>(I.e. during the file creation, a handle is created, used for writing, then closed. During the file processing portion, a separate file handle opens the file, reads from it, and is closed at EOF. And <em>finally</em>, delete uses ::DeleteFile which only has use of a filename, not a file handle at all).</p>
<p>Recently we've come to realize that a particular macro (script) fails sometimes to be able to create the file at some random subsequent time (i.e. it succeeds during the first hundred iterations of "create, process, delete", but when it comes back to creating it a hundred and first time, Windows replies "Access Denied").</p>
<p>Looking deeper into the issue, I have written a very simple program that loops over something like this:</p>
<pre><code>while (true) {
HANDLE hFile = CreateFileA(pszFilename, FILE_ALL_ACCESS, FILE_SHARE_READ,
NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL);
if (hFile == INVALID_HANDLE_VALUE)
return OpenFailed;
const DWORD dwWrite = strlen(pszFilename);
DWORD dwWritten;
if (!WriteFile(hFile, pszFilename, dwWrite, &dwWritten, NULL) || dwWritten != dwWrite)
return WriteFailed;
if (!CloseHandle(hFile))
return CloseFailed;
if (!DeleteFileA(pszFilename))
return DeleteFailed;
}
</code></pre>
<p>As you can see, this is direct to the Win32 API and is pretty darn simple. I create a file, write to it, close the handle, delete it, rinse, repeat...</p>
<p>But somewhere along the line, I'll get an Access Denied (5) error during the CreateFile() call. Looking at sysinternal's ProcessMonitor, I can see that the underlying issue is that there is a pending delete on the file while I'm trying to create it again.</p>
<p><strong>Questions:</strong></p>
<ul>
<li>Is there a way to wait for the delete to complete?</li>
<li>Is there a way to detect that a file is pending deletion?</li>
</ul>
<p>We have tried the first option, by simply WaitForSingleObject() on the HFILE. But the HFILE is always closed before the WaitForSingleObject executes, and so WaitForSingleObject always returns WAIT_FAILED. Clearly, trying to wait for the closed handle doesn't work.</p>
<p>I could wait on a change notification for the folder that the file exists in. However, that seems like an extremely overhead-intensive kludge to what is a problem only occasionally (to wit: in my tests on my Windows 7 x64 E6600 PC it typically fails on iteration 12000+ -- on other machines, it can happen as soon as iteration 7 or 15 or 56 or never).</p>
<p>I have been unable to discern any CreateFile() arguments that would explicitly allow for this ether. No matter what arguments CreateFile has, it really is not okay with opening a file for <em>any</em> access when the file is pending deletion.</p>
<p>And since I can see this behavior on both an Windows XP box and on an x64 Windows 7 box, I am quite certain that this is core NTFS behavior "as intended" by Microsoft. So I need a solution that allows the OS to complete the delete before I attempt to proceed, preferably without tying up CPU cycles needlessly, and without the extreme overhead of watching the folder that this file is in (if possible).</p>
<p><a href="https://stackoverflow.com/questions/3764072/c-win32-how-to-wait-for-a-pending-delete-to-complete/3764298#3764298">1</a> Yes, this loop returns on a failure to write or a failure to close which leaks, but since this is a simple console test application, the application itself exits, and Windows guarantees that all handles are closed by the OS when a process completes. So no leaks exist here.</p>
<pre><code>bool DeleteFileNowA(const char * pszFilename)
{
// Determine the path in which to store the temp filename
char szPath[MAX_PATH];
strcpy(szPath, pszFilename);
PathRemoveFileSpecA(szPath);
// Generate a guaranteed to be unique temporary filename to house the pending delete
char szTempName[MAX_PATH];
if (!GetTempFileNameA(szPath, ".xX", 0, szTempName))
return false;
// Move the real file to the dummy filename
if (!MoveFileExA(pszFilename, szTempName, MOVEFILE_REPLACE_EXISTING))
return false;
// Queue the deletion (the OS will delete it when all handles (ours or other processes) close)
if (!DeleteFileA(szTempName))
return false;
return true;
}

FFT real/imaginary/abs parts interpretation
|
<p>I'm currently learning about discret Fourier transform and I'm playing with numpy to understand it better.</p>
<p>I tried to plot a "sin x sin x sin" signal and obtained a clean FFT with 4 non-zero points. I naively told myself : "well, if I plot a "sin + sin + sin + sin" signal with these amplitudes and frequencies, I should obtain the same "sin x sin x sin" signal, right?</p>
<p>Well... not exactly</p>
<p>(First is "x" signal, second is "+" signal)</p>
<p><img src="https://i.stack.imgur.com/AlE2o.png" alt="enter image description here"></p>
<p>Both share the same amplitudes/frequencies, but are not the same signals, even if I can see they have some similarities.</p>
<p>Ok, since I only plotted absolute values of FFT, I guess I lost some informations.</p>
<p>Then I plotted real part, imaginary part and absolute values for both signals :</p>
<p><img src="https://i.stack.imgur.com/Rqa7T.png" alt="enter image description here"></p>
<p>Now, I'm confused. What do I do with all this? I read about DFT from a mathematical point of view. I understand that complex values come from the unit circle. I even had to learn about Hilbert space to understand how it works (and it was painful!...and I only scratched the surface). I only wish to understand if these real/imaginary plots have any <em>concrete</em> meaning outside mathematical world:</p>
<ul>
<li>abs(fft) : frequencies + amplitudes</li>
<li>real(fft) : ?</li>
<li>imaginary(fft) : ?</li>
</ul>
<p>code :</p>
<pre><code>import numpy as np

How to use dup2/close correctly to connect these three processes?
|
<p>I'm trying to properly connect three processes in order to allow inter-process communication between them. I have one process, scanner, which takes the parent's STDIN and then processes the words within the stream. If a word length is odd, it sends it to one process, if it is even, it sends it to another. These processes should take in these words via STDIN (I assume) and then output some info back to the scanner process via STDOUT. The STDOUT of even/odd should be redirected to scanner, which will then read (using read) and then output/process the words. It's an academic exercise, not a practical one. Here's what a picture of it would look like:</p>
<p><img src="https://i.stack.imgur.com/wXtMq.png" alt="Pipe setup"></p>
<p>Here's what my code currently looks like. The problem is I'm not exactly sure what to dup and what to close. Once I figure that out I should be good to go! Any advice would be appreciated.</p>
<p>File descriptors:</p>
<pre><code>int scannertoeven[2]; int scannertoodd[2];
int eventoscanner[2]; int oddtoscanner[2];
//Pipe stuff here (ommitted)
</code></pre>
<p>Code:</p>
<pre><code> //Create the child processes
if ((scanner_pid = fork()) == 0) {
//We need the scanner pid so even and odd can send signals to it
char pidofparent[sizeof(getpid())];
sprintf(pidofparent, "%i", getpid());
//Even stuff
if ((even_pid = fork()) == 0) {
close(scannertoodd[0]); close(scannertoodd[1]);
close(oddtoscanner[0]); close(oddtoscanner[1]);
//Not sure which ones to close
close(scannertoeven[0]); close(scannertoeven[1]);
close(eventoscanner[0]); close(eventoscanner[1]);
//Correct?
close(STDIN_FILENO);
dup2(scannertoeven[0], STDIN_FILENO);
close(STDOUT_FILENO);
dup2(eventoscanner[1], STDOUT_FILENO);
if(execl("./evenodd", "even", pidofparent, NULL ) == -1) {
printf("execl Error!");
exit(1);
}
//Odd Stuff
} else if ((odd_pid = fork()) == 0){
close(scannertoeven[0]); close(scannertoeven[1]);
close(eventoscanner[0]); close(eventoscanner[1]);
//Not sure which ones to close
close(scannertoodd[0]); close(scannertoodd[1]);
close(oddtoscanner[0]); close(oddtoscanner[1]);
//Correct?
close(STDIN_FILENO);
dup2(scannertoodd[0], STDIN_FILENO);
close(STDOUT_FILENO);
dup2(oddtoscanner[1], STDOUT_FILENO);
if(execl("./evenodd", "odd", pidofparent, NULL ) == -1) {
printf("execl Error!");
exit(1);
}
//Actual Scanner
} else {
// Not sure which ones to close- this is very wrong
close(scannertoeven[0]); close(scannertoeven[1]);
close(eventoscanner[0]); close(eventoscanner[1]);
close(scannertoodd[0]); close(scannertoodd[1]);
close(oddtoscanner[0]); close(oddtoscanner[1]);

dup2(scannertoeven[1], STDOUT_FILENO);

Are there alternatives to using Google's in-app-billing , as a way to avoid publishing private info?
|
<h2>Background</h2>
<p>Starting from September 30th this year (end of this month), Google won't allow developers that sell apps and developers that use in-app-billing to show their apps without also showing their address . Here's what they write:</p>
<blockquote>
<p>Add a physical contact address Beginning September 30, 2014, you need
to add a physical address to your Settings page. After you've added an
address, it will be available on your app's detail page to all users
on Google Play. If your physical address changes, make sure to update
your information on your Settings page.</p>
<p>If you have paid apps or apps with in-app purchases, it's mandatory to
provide a physical address where you can be contacted, as you are the
seller of that content, to comply with consumer protection laws. If
you don't provide a physical address on your account, it may result in
your apps being removed from the Play Store.</p>
</blockquote>
<p>There are plenty of articles about this new requirement:</p>
<ul>
<li><a href="http://www.androidauthority.com/google-forcing-developers-to-publish-home-addresses-527772/" rel="noreferrer">http://www.androidauthority.com/google-forcing-developers-to-publish-home-addresses-527772/</a></li>
<li><a href="http://www.androidpolice.com/2014/09/18/google-will-now-require-all-app-publishers-with-paid-apps-or-in-app-purchases-to-have-an-address-on-file-in-google-play/" rel="noreferrer">http://www.androidpolice.com/2014/09/18/google-will-now-require-all-app-publishers-with-paid-apps-or-in-app-purchases-to-have-an-address-on-file-in-google-play/</a></li>

</ul>
<p>There are even petitions against it , here:</p>
<ul>
<li><a href="https://www.change.org/p/google-remove-the-need-for-developers-to-reveal-their-physical-addresses-publicly-on-google-play" rel="noreferrer">https://www.change.org/p/google-remove-the-need-for-developers-to-reveal-their-physical-addresses-publicly-on-google-play</a></li>
<li><a href="https://www.change.org/p/google-inc-reverse-your-decision-to-require-android-developers-who-sell-apps-on-google-play-to-publicly-disclose-their-physical-address?lang=en-US" rel="noreferrer">https://www.change.org/p/google-inc-reverse-your-decision-to-require-android-developers-who-sell-apps-on-google-play-to-publicly-disclose-their-physical-address?lang=en-US</a></li>
</ul>
<p>And I've requested to have a solution for it <a href="https://code.google.com/p/android-developer-preview/issues/detail?id=1340" rel="noreferrer"><strong>here</strong></a>.</p>
<h2>The problem</h2>
<p>As I don't really have a company, I don't like the fact I will actually need to publish my home address. </p>
<p>For me, it's a privacy issue, as I don't always work on the app at home (plus it's more of a hobby).</p>
<p><a href="https://play.google.com/store/apps/details?id=com.lb.app_manager" rel="noreferrer"><strong>My app</strong></a> is free to use, and it has in-app-billing only used to remove ads. That's it.</p>
<p>It doesn't add any feature when using in-app-billing, and the user is free to pay whatever he wishes, as a donation.</p>
<p>I do not want to publish my address, and according to what I've read, you can't even use a P.O. box (which costs money anyway), as they specifically ask for "Physical address" and not "postal address".</p>
<h2>The question</h2>
<p>Since I will probably not be able to use Google's in-app-billing AND avoid putting my home address, is it possible (and legal, and according to Google's rules) to use other services of other companies?</p>
<p>If so, which companies offer similar services?</p>
<p>If not, is there any alternative or a solution to this problem?</p>
<p>Is there maybe a workaround or a loophole that will allow me to publish such apps without the reason to also publish my home address?</p>

Java homework hangman
|
<p>So for a class we are having to make a hangman game that can take a user input for a word and then have another person solve for it. It has to be able to recognize multiple repeating letters in the word or I would be done. Below is my code, it works great until I remove the break statement in my checkformatch method so that it goes past the initial finding of a letter. With the break in there it never finds the second third etc repeated letters, without it, it returns that each letter that is not the letter searched is a miss and reduces my life count. What I'm needing is some hints on how to search my array for the letter that is inputted as a guess and return their index positions in the array without it thinking each character in the array that is not the one guessed is a wrong input. Thank you in advance.</p>
<pre><code>package hangman;
import java.util.Scanner;
class Game {
int livesRemaining;
String letterGuessed;
String wordInput;
char[] hiddenWord;
char[] aOfWord ;
Scanner input = new Scanner(System.in);
boolean isFound;
int a;
public Game()
{
this.setLives(8);
//this.output();
System.out.println("Player 1 please enter the word to be searched: ");
wordInput = input.nextLine();
aOfWord = wordInput.toCharArray();
hiddenWord = new char[aOfWord.length];
for(int j = 0; j < hiddenWord.length; j++)
hiddenWord[j] = '*';
this.output();
while(livesRemaining > 0)
{
System.out.println("Please choose a letter: ");
letterGuessed = input.nextLine();
this.checkForMatch(letterGuessed);
if(isFound == true)
{
hiddenWord[a] = letterGuessed.charAt(0);
}
else
{
System.out.println("Is not found!");
this.reduceLives();
}
this.output();
}
}
public void setLives(int a)
{
this.livesRemaining = a;
}
public void reduceLives()
{
livesRemaining = livesRemaining -1;
System.out.println("Lives remaining: " + this.getLives());
}
public int getLives()
{
return livesRemaining;
}
public void output()
{
System.out.println("Lives remaining: " + this.getLives());
System.out.println("Word found so far ");
for(int i = 0; i < hiddenWord.length; i++)
{
System.out.print(hiddenWord[i] + "\n");
}
}
public void checkForMatch(String l)
{
for(int i = 0; i < aOfWord.length; i++)
{
//System.out.println("Comparing " + l.charAt(0) + " To " + aOfWord[i]);
if(l.charAt(0) == aOfWord[i])
{
isFound = true;
a = i;

Private fields from abstract class cannot be accessed in the subclass
|
<p>I have class which represents every object in my simple game (player, enemy, beam etc - they all have many commons like speed, position, dmg). So i made class named Thing. Here is how it looks like:</p>
<pre><code>public abstract class Thing {
private Image image;
private float x;
private float y;
private float speed;
private final int WIDTH;
private final int HEIGHT;
public Thing(String filename, float x, float y, float speed) {
try {
Image image = ImageIO.read(new File(filename));
} catch (Exception e) {}
this.x = x;
this.y = y;
this.speed = speed;
WIDTH = image.getWidth(null);
HEIGHT = image.getHeight(null);
}
//Zwraca ksztalt do sprawdzania czy contains...
public Rectangle2D getShade() {
return new Rectangle2D.Float(x, y, WIDTH, HEIGHT);
}
public Image getImage() {
return image;
}
public Point2D getPoint() {
return new Point2D.Float(x, y);
}
public float getX() {
return x;
}
public float getY() {
return y;
}
}
</code></pre>
<p>I have extended the class Player:</p>
<pre><code>public class Player extends Thing {
public Player(String filename, float x, float y, float speed) {
super(filename, x, y, speed);
}
public void moveToPoint(Point2D targetPoint) {
int targetX = (int)targetPoint.getX();
int targetY = (int)targetPoint.getY();
if ( ((int)x+20 < targetX+3) && ((int)x+20 > targetX-3) ) {
return;
}
float distanceX = targetX - x;
float distanceY = targetY - y;
//Dodanie 20px wymiarow statku
distanceX -= 20;
distanceY -= 20;
//Ustalenie wartosci shiftow
float shiftX = speed;
float shiftY = speed;
if (abs(distanceX) > abs(distanceY)) {
shiftY = abs(distanceY) / abs(distanceX) * speed;
}
if (abs(distanceY) > abs(distanceX)) {
shiftX = abs(distanceX) / abs(distanceY) * speed;
}
//Zmiana kierunku shifta w zaleznosci od polozenia
if (distanceX < 0) {
shiftX = -shiftX;
}
if (distanceY < 0) {
shiftY = -shiftY;
}
//Jezeli statek mialby wyjsc poza granice to przerywamy
if ( (((int)x+shiftX < 0) || ((int)x+shiftX > 260)) || ((y+shiftY < 0) || (y+shiftY > 360)) ) {
return;
}
//Zmiana pozycji gracza
x += shiftX;
y += shiftY;
}
}
</code></pre>
<p>And here is the problem because my IDE underlines x, y and speed fields red and tells they cannot be accessed from Player class. I tried to change them into private and default but there appears an error after that. What am I doing wrong? When i create new object from class which extends Thing I want to copy all fields and init them as it is said in constructor. So how to repair it?</p>

iOS 11 Layout guidance about safe Area for iPhone x
|
<p>My application already in app store, yesterday i have updated my Xcode version to 9 and works fine except <strong>iPhone x</strong>. UI got collapsed.</p>
<p>1.Here I have Created Two <strong>UIView</strong>(both are fixed height) named as Header and Tab bar and I have hidden my <strong>NavigationBar</strong> entire app.</p>
<p>2.Added extension to <strong>UIViewController</strong> for making <strong>Header</strong> and <strong>Tab bar</strong></p>
<pre><code>func addHeaderTab(currentViewController:UIViewController,content:String, isMenu:Bool){
let noView = TopHeaderView()
noView.tag = 12345
noView.isMenu = isMenu
noView.translatesAutoresizingMaskIntoConstraints = false
currentViewController.view .addSubview(noView)
if isMenu{
noView.menuBtn .setImage(UIImage(named: "Small"), for: .normal)
noView.logoImg.isHidden = false
}else{
noView.menuBtn .setImage(UIImage(named: "arrow_small"), for: .normal)
noView.logoImg.isHidden = true
}
noView.titleLbl.text = content
noView.delegate = (currentViewController as! menuOpen)
NSLayoutConstraint(item: noView, attribute: .leading, relatedBy: .equal, toItem: currentViewController.view, attribute: .leading, multiplier: 1.0, constant: 0.0).isActive = true
NSLayoutConstraint(item: noView, attribute: .trailing, relatedBy: .equal, toItem: currentViewController.view, attribute: .trailing, multiplier: 1.0, constant: 0.0).isActive = true
NSLayoutConstraint(item: noView, attribute: .top, relatedBy: .equal, toItem: currentViewController.view, attribute: .top, multiplier: 1.0, constant: 0.0).isActive = true
NSLayoutConstraint(item: noView, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .height, multiplier: 1.0, constant: 64).isActive = true
}
</code></pre>
<p>and calling this every <strong>Viewcontroller</strong> like below :</p>
<pre><code>self.addHeaderTab(currentViewController: self, content:"நிகழ்ச்சி நிரல்" , isMenu: true)
</code></pre>
<p>Like that Tab bar also i have done but all the device working expect <strong>iPhone x</strong>.</p>
<p>See My screen shot : </p>
<p><a href="https://i.stack.imgur.com/1us5e.png" rel="noreferrer"><img src="https://i.stack.imgur.com/1us5e.png" alt="Image"></a></p>
