C: using realloc for high performance with an array of structs
|
<p>I am using realloc to adjust the size of an array of structs containing 3 points x, y and z. This struct is encapsulated inside another struct that contains the array, the length of the array and a "reserved" value that is used for a pre-allocation strategy for even faster performance when it is evident that more structs of points will be appended to the struct array.<br>
I am compiling with a Makefile that looks like this:</p>
<pre><code>CFLAGS = -g -Wall
LIBS = -lm
default: echo "You must specify a target, e.g. file1, file2"
file2:
gcc $(CFLAGS) -o $@ test.c file2.c $(LIBS)
</code></pre>
<p>I have a function to initialize an empty array structure, one to reset the array to be empty and free any dynamically allocated memory, one to append a point to the end of the array and one to remove a point designated by the index value. </p>
<p>I am getting two errors that I cannot find the cause of. One is that my code returns a non-zero status code of 1 and the other is the length seems to be off by one when I append a few thousand points.<br>
I am letting the append function do all the work but if I should be allocating dynamic memory in initialization, please tell me so. I am pretty sure that my reset and remove functions are working as they are supposed to. Please take a look at append as well. </p>

Shared Compass/Lucene Index in JDBC Store
|
<p>Using the searchable plugin in Grails (which uses Compass/Lucene under the hood) we're trying to share a search index between two different web applications. One application accesses the data only in a read-only fashion. The other application allows to modify the data and is in charge of updating the index on any change or do a full re-index on demand.</p>
<p>To store the index we're using the JDBC Store (with both applications pointing to the same DB) <a href="http://www.compass-project.org/docs/latest/reference/html/core-connection.html" rel="nofollow">http://www.compass-project.org/docs/latest/reference/html/core-connection.html</a>.</p>
<p>Unfortunately, as soon as we rebuild the whole index in one application, the other application seems to have invalid data cached and an exception is thrown if a search is performed:</p>
<pre><code>| Error 2012-05-30 09:22:07,560 [http-bio-8080-exec-8] ERROR errors.GrailsExceptionResolver - IndexOutOfBoundsException occurred when processing request: [POST] /search

<p>We could communicate the fact that the index is rebuilt from one to the other application so that some clean-up could be performed.</p>
<ul>
<li>Did anybody have a similar problem with Grails and the Searchable plugin?</li>
<li>Is it possible to discard data cached by Compass/Lucene?</li>
<li>Is it possible to disable caching generally?</li>

<p>There is more of it but I am sending the first one because others are mostly the same.</p>
<p>When I was debugging. It mostly gives undefined.
I have made the API in Django. From the backend side, it works well. But from the front end, it doesn't. I am fresher in react I am making the project to learn it, therefore, the react code is not industry standard</p>

Near Protocol NFT add string values mapped to a TokenId. i.e. tokenizing an ipfs hash
|
<p>I am trying to learn how to use the Near protocol and Rust by recreating my NFT Dapp which mapped string values (ipfs hash's to be exact) which I call a "sketch".
I have already done this successfully using Solidity on Ethereum. example shown at bottom of this page.</p>
<p><strong>I am simply trying to map string values to a tokenId and subsequently an OwnerId. I have used the boilerplate NFT lib.rs found on the <a href="https://examples.near.org/NFT" rel="nofollow noreferrer">Near dev NFT website</a> and have added my own string mapping for collections of "sketch" which will just contain an ipfs hash value to be used later on the front-end as an image source. What I have for lib.rs is below.</strong></p>

<p>If it is any consolation, what I did in Solidity was map "sketch" as strings and push their value while adding the token Id based on the sketch array's length through to the ERC721.sol contract as shown below:</p>
<pre><code>
pragma solidity ^0.6.0;
import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
contract Sketch is ERC721, Ownable{
address payable private admin;
string[] public sketchs;
mapping(string => bool) _sketchExists;
constructor() ERC721("Sketch", "SKETCH") public {
admin = msg.sender;
}
/// @notice mints the ipfs hash passed from the console
/// @dev example input for _sketch is an ipfs hash ("QmdMuGrMCfvgwg7F6WM8CHev9PJxQ2n3f49ttSGuYfK4Qp")
function mint(string memory _sketch) public {
require(!_sketchExists[_sketch]);
sketchs.push(_sketch);
uint _id = sketchs.length - 1;
_safeMint(msg.sender, _id,'');
_sketchExists[_sketch] = true;
}
function transfersketch(address _to, uint _id) public {
safeTransferFrom(msg.sender, _to, _id);
}
}
</code></pre>
<p>Am I in the right direction? Any help would be really appreciated. Thanks in advance!</p>

Angular 5 - How to dynamically add event on a DOM element?

<p>I'm try to implement a search input as the one on "Medium" website by adding a new suggestion (based on the input context for full text search) at the top of the list of the current suggestions. I'm on an angular 5 project and I use typeahead for research module. </p>

Slow reading from CSV file
|
<p>I'm trying to read from a csv file but it's slow. Here's the code roughly explained:</p>
<pre><code>private static Film[] readMoviesFromCSV() {
// Regex to split by comma without splitting in double quotes.
// https://regexr.com/3s3me <- example on this data
var pattern = Pattern.compile(",(?=(?:[^\\\"]*\\\"[^\\\"]*\\\")*[^\\\"]*$)");
Film[] films = null;
try (var br = new BufferedReader(new FileReader(FILENAME))) {
var start = System.currentTimeMillis();
var temparr = br.lines().skip(1).collect(Collectors.toList()); // skip first line and read into List
films = temparr.stream().parallel()
.map(pattern::split)
.filter(x -> x.length == 24 && x[7].equals("en")) // all fields(total 24) and english speaking movies
.filter(x -> (x[14].length() > 0)) // check if it has x[14] (date)
.map(movieData -> new Film(movieData[8], movieData[9], movieData[14], movieData[22], movieData[23], movieData[7]))
// movieData[8] = String title, movieData[9] = String overview
// movieData[14] = String date (constructor parses it to LocalDate object)
// movieData[22] = String avgRating
.toArray(Film[]::new);
System.out.println(MessageFormat.format("Execution time: {0}", (System.currentTimeMillis() - start)));
System.out.println(films.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return films;
}
</code></pre>
<p>File is about 30 MB big and it takes about 3-4 seconds avg. I'm using streams but it's still really slow. Is it because of that splitting each time?</p>
<p><strong>EDIT:</strong> I've managed to speed up reading and processing time by 3x with uniVocity-parsers library. On average it takes 950 ms to finish. That's pretty impressive.</p>
<pre><code>private static Film[] readMoviesWithLib() {
Film[] films = null;
CsvParserSettings parserSettings = new CsvParserSettings();
parserSettings.setLineSeparatorDetectionEnabled(true);
RowListProcessor rowProcessor = new RowListProcessor();
parserSettings.setProcessor(rowProcessor);
parserSettings.setHeaderExtractionEnabled(true);
CsvParser parser = new CsvParser(parserSettings);
var start = System.currentTimeMillis();
try {
parser.parse(new BufferedReader(new FileReader(FILENAME)));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
List<String[]> rows = rowProcessor.getRows();
films = rows.stream()
.filter(Objects::nonNull)
.filter(x -> x.length == 24 && x[14] != null && x[7] != null)
.filter(x -> x[7].equals("en"))
.map(movieData -> new Film(movieData[8], movieData[9], movieData[14], movieData[22], movieData[23], movieData[7]))
.toArray(Film[]::new);
System.out.printf(MessageFormat.format("Time: {0}",(System.currentTimeMillis()-start)));
return films;
}

How to append an element to a dynamically generated element
|
<p>I have several forms one clone after another depends on the user input. in each form I have button to add a row of input:</p>
<pre><code><h4>3.3.5 Input Parameters</h4>
<table id="input_param" data-role="table" class="ui-responsive table-stroke">
<thead>
<tr>
<th data-priority="1">Parameter</th>
<th data-priority="2">Data Type</th>
<th data-priority="3">Required</th>
<th data-priority="4">Brief description</th>
<th data-priority="5">Location in Request</th>
</tr>
</thead>
<tbody></tbody>
</table>
<input type="button" id="add_input_param" value="+ Add Input Parameter" data-inline="true" /><br />
</code></pre>
<p>so if it's the first form(static form) than this code will work:</p>
<pre><code>$("#add_input_param").click(function() {
var maincontent = loadParam('IP', '01', ipCount);
ipCount++;
$('#input_param').append(maincontent).trigger("create");
});
</code></pre>
<p>because the one after the first one I understand I have to use .on() </p>
<pre><code>$("#input_form").on("click", "#add_input_param", function() {
var maincontent = loadParam('IP', '01', ipCount);
ipCount++;
//$('this').append(maincontent).trigger("create");
});
</code></pre>
<p>the comment area is the part that I cannot get it work. I would like to append the maincontent to #input_param (it's a table), but because it's dynamically generated how can I modify that line of code so it will work with it?</p>
<p>maincontent will be something like this:</p>
<pre><code>function loadParam(IO, form_number, counter) {
var id = IO + form_number + '-' + counter;
var maincontent = '<tr>';
maincontent += '<th><input type="text" name="param' + id + '" id="param' + id + '" value="" /></th>';
maincontent += '<td><input type="text" name="data_type' + id + '" id="data_type' + id + '" /></td>';
maincontent += '<td>';
maincontent += '<select id="required" name="req' + id + '" id="req' + id + '"class="form-alpha">';
maincontent += '<option value="Mandatory" >Mandatory</option>';
maincontent += '<option value="Optional" >Optional</option>';
maincontent += '<option value="Conditional" >Conditional</option>';
maincontent += '</select>';
maincontent += '</td>';
maincontent += '<td><textarea name="des' + id + '" id="des' + id + '" ></textarea></td>';
maincontent += '<td>';
maincontent += '<select name="location' + id + '" id="location' + id + '" class="form-alpha">';
maincontent += '<option value="Header" >Header</option>';
maincontent += '<option value="Body" >Body</option>';
maincontent += '<option value="Query_param" >Query Parameter</option>';
maincontent += '<option value="Resource_uri" >Resource URI</option>';
maincontent += '</select>';
maincontent += '</td>';
maincontent += '</tr>';
return maincontent;
}

Java reflection vs non reflection performance comparison
|
<p>So I tried to test the performance of java reflection. I want to add every value of every field in a class into a map.</p>
<pre><code> public static class testClass {
String monday = "Monday";
String tuesday = "Tuesday";
String wednesday = "Wednesday";
String thursday = "Thursday";
String friday = "Friday";
String saturday = "Saturday";
String sunday = "Sunday";
... getter and setters ...
}
public static void main(String args[]) {
noReflection();
reflection();
}
public static void noReflection() {
testClass test = new testClass();
long start = System.nanoTime();
Map myMap = new HashMap<>();
for (int i = 0; i < RUNS; i++) {
List<Integer> myList = new ArrayList<>();
for(myDayz days: myDayz.values()) {
myList.add(days.ordinal());
}
myMap.put(myList.get(0),test.getMonday());
myMap.put(myList.get(1),test.getFriday());
myMap.put(myList.get(2),test.getSaturday());
myMap.put(myList.get(3),test.getSunday());
myMap.put(myList.get(4),test.getThursday());
myMap.put(myList.get(5),test.getTuesday());
myMap.put(myList.get(6),test.getWednesday());
myMap.clear();
}
System.out.printf("no reflection: %,d ns%n", (System.nanoTime() - start)/RUNS);
}
public static void reflection() {
testClass as = new testClass();
long start = System.nanoTime();
final String stringClassName = String.class.getName();
Map myMap = new HashMap<>();
for (int i = 0; i < RUNS; i++) {
int enumIndex = 0;
List<Integer> myList = getEnumsAsList(myDayz.class);
for(Field field : as.getClass().getDeclaredFields()) {
field.setAccessible(true);
String fieldTypeName = field.getGenericType().getTypeName();
try {
Object instance = field.get(as);
if (instance != null && fieldTypeName.equals(stringClassName)) {
myMap.put(myList.get(enumIndex),(String) instance);
enumIndex++;
}
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
myMap.clear();
}
System.out.printf("reflection: %,d ns%n", (System.nanoTime() - start)/RUNS);
}
private static <E extends Enum<E>> List<Integer> getEnumsAsList(Class<E> eClass) {

enumOrdinals.add(en.ordinal());
}
return enumOrdinals;
}
private enum myDayz {
MONDAY,
TUESDAY,
WEDNESDAY,
THURSDAY,
FRIDAY,
SATURDAY,
SUNDAY
}
</code></pre>
<p>Now what suprised me is that the non reflection code is about ~60% faster. I thought it would be ALOT faster. My question is if this is what you can expect or have i done something wrong here?</p>

How to debug with GDB on RT Linux: fails with SIGTRAP
|
<p>I am trying to debug a multi threaded application on RT Linux. On regular Linux, the app runs fine, and GDB also runs fine. On RT Linux the app runs fine, but under GDB, the app runs for several seconds then terminates and prints:</p>
<p><code>Program terminated with signal SIGTRAP, Trace/breakpoint trap. The program no longer exists.</code></p>
<p>I cannot do a backtrace, or determine what is causing the problem. I suspect it might be some libraries used by gdb, or else maybe memory corruption in the app.</p>
<p>I create over sixty threads, and many more are created by various watchdogs and timers.
What I have tried so far:</p>
<ol>
<li><p>Checking for mismatch between libpthread.so.0 and libthread_db.so.1. I used </p>
<p><code>objdump -s --section .comment /usr/lib64/libthread_db-1.0.so</code></p></li>
</ol>
<p>on both libraries, and they both gave the same version of gcc, which is the same gcc I am using to build the app </p>
<p><code>gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)</code></p>
<ol start="2">
<li><p>Trying to set a catchpoint for SIGTRAP in gdb with</p>
<p><code>catch signal SIGTRAP
commands
p $_siginfo.si_code
end</code></p></li>
</ol>
<p>This did not alter behaviour of gdb at all.
Any ideas? New kernel libraries or sources that I should download?</p>
<p><strong>Versions:</strong>
My original linux was Scientific Linux 7 downloaded from the CERN repo (based on CentOS 7). I also downloaded and installed the prebuilt RT kernel from there.</p>
<p><code># gdb --version
GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-114.el7</code></p>
<p><code># uname -r
3.10.0-957.10.1.rt56.921.el7.x86_64</code></p>
<p><code>gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)</code></p>
<p><strong>Some Progress</strong>
Several times gdb itself crashed and left a gdb core dump. Backtracing into gdb using the core file, I found the same call stack -- last few functions shown below:</p>
<pre><code>(gdb) bt
#0 0x00007fc62ca9e207 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:55

#11 0x0000000000607602 in target_wait ()
#12 0x00000000005cf815 in wait_for_inferior ()
</code></pre>
<p>This seems to indicate a problem with gdb, so I rebuilt gdb using the latest source (8.2.1) and this stopped the gdb crashes. Now GDB stops at many kernel calls (sleep, semwait etc) with a SIGSTOP, I can press continue, but this makes debugging impractical.</p>
<p>If I add the following line to .gdbinit <code>handle SIGSTOP nostop noprint pass</code> then gdb does not stop at kernel calls, but now breakpoints don't work and it is very difficult to stop either gdb or the process being debugged.</p>

Python multiprocessing issue with arguments set/list completion of processes
|
<p>This other post is exactly, I think, regarding what i want to do.
<a href="https://stackoverflow.com/questions/5442910/python-multiprocessing-pool-map-for-multiple-arguments">Python multiprocessing pool.map for multiple arguments</a></p>
<p>How I am trying to implement is in my pseudo code:</p>
<h1>called by another function in my code</h1>
<pre><code>def find_similar(db, num, listofsets):
#db is the sqlite3 database
#num is a variable I need for the sql query
#listofsets - is a list of sets. each set is a set of strings
threshold = 0.49
similar_db_rows=[]
for row in db.execute("SELECT thing1, thing2, thing3 FROM table WHERE num !={n};".format(n=num)):
#thing3 is a long string, each value separated by a comma
items = set(row[3].strip().split(','))
for set_item in listofsets:
sim_score = sim_function(set_item, items)
if sim_score<threshold:
similar_db_rows.append(row)
return similar_db_rows
def sim_function(x,y):
#x is a set, and y is a second set. The function does some calculation
and comparing, then returns a float value
return float_value
</code></pre>
<p>This works. What I was trying to do was use multiprocessing on the 2nd for loop. Instead of iterating each set (as my list of sets can have a lot, and this is a major bottle neck) and calling the function, I wanted to use multiprocessing so that it would call the function for these sets, passing a set along with the second constant argument from the sqlquery, many at a time, then return the resulting number from each set into a list. After all of the sets have been processed, then I can use the items in that list to check if any item meets a threshold.</p>
<p>I tried to use the <code>func_star</code> and <code>pool.map(func_star, itertools.izip(a_args, itertools.repeat(second_arg)))</code> by Sebestian AND the `parmap' by zeehio. But for me, for example if I had 30 sets in the list, it was returning a list of results more than 30 times, each return it would check for similarity threshold, and appending rows, but never breaking out of this and I end up control Z'ing the whole thing.</p>
<p>Below is an example of what I attempted, first using parmap:</p>
<pre><code>def find_similar(db, num, listofsets):
#db is the sqlite3 database
#num is a variable I need for the sql query
#listofsets - is a list of sets. each set is a set of strings
threshold = 0.49
list_process_results=[]
similar_db_rows=[]
for row in db.execute("SELECT thing1, thing2, thing3 FROM table WHERE num !={n};".format(n=num)):
items = set(row[3].strip().split(','))
list_process_results = parmap.starmap(sim_function, zip(listofsets), items)
print list_process_results
if any(t < threshold for t in list_process_results):
#print "appending a row"
similar_db_rows.append(row)
return similar_db_rows
</code></pre>
<p>and <code>func_star</code>:</p>
<pre><code>def func_star(a_b):
"""Convert `f([1,2])` to `f(1,2)` call."""
return sim_function(*a_b)
def find_similar(db, num, listofsets):
pool = Pool()

<p>The same is happening for me with both, it goes on forever, returning a list of the # I am expecting (a different set of values each time), "appending a row", and never breaking out.</p>
<p>Thanks for the help!!! extra is if multiprocessing can also be used for the results of the row query (the outer loop) but i will first conquer the inner loop</p>
<p>To answer Dano question about <code>find_similar</code>()---
I have another function that has a for loop. Each iteration of this for loop calls <code>find_similar</code>. When the resulting list is returned from <code>find_similar</code>, it prints the length of the list return, it then proceeds to finish the remainder of the loop, and go to the next for element. After this for loop is finished, the function is over, and <code>find_similiar</code> is not called again.</p>

Javascript calculator equal function failing
|
<p>I have created a calculator using JavaScript. When I chain together multiple math problems I get the answer I desire until I try and get the end result with the = button. When I do only two numbers the = button works perfectly fine. I have my code set up to set the a mathHoldOne and mathHoldTwo. Both contain a number and a boolean if its set or not. I have checked dev tools to see what the difference is between a problem with two numbers and a problem with 2+ numbers and I can't seem to find the issue. <a href="https://codepen.io/tchbell/full/WdjxdG/" rel="nofollow noreferrer">codepen</a></p>

Popup in style of ContentControl not updating
|
<p>I have a ContentControl with a style that contains a popup that wraps a textbox. I know it sounds a little confusing but I will post some code below. When the caps lock key is on the popup is shown, but when the window is dragged the popup does not move with it. </p>
<p>I need to figure out how to update the location of the popup in they style. </p>
<p>This ContentControl is used on both a window and UserControl so that is why I am trying to address this in the style.</p>
<p>This question differs from some of the others as I am trying to solve it in the style and not code.</p>
<p>The content control:</p>
<pre><code>public class ShowCapLockWarningControler : ContentControl
{
static ShowCapLockWarningControler()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(ShowCapLockWarningControler), new FrameworkPropertyMetadata(typeof(ShowCapLockWarningControler)));
}
public static readonly DependencyProperty ShowMessageProperty =
DependencyProperty.Register(Reflection.GetPropertyName<ShowCapLockWarningControler>(i => i.ShowMessage), typeof(bool),
typeof(ShowCapLockWarningControler), new PropertyMetadata(false));
public bool ShowMessage
{
get { return (bool)GetValue(ShowMessageProperty); }
set { SetValue(ShowMessageProperty, value); }
}
public ShowCapLockWarningControler()
{
IsKeyboardFocusWithinChanged += (s, e) => RecomputeShowMessage();
PreviewKeyDown += (s, e) => RecomputeShowMessage();
PreviewKeyUp += (s, e) => RecomputeShowMessage();
}
private void RecomputeShowMessage()
{
ShowMessage = IsKeyboardFocusWithin && Console.CapsLock;
}
}
</code></pre>
<p>How its used:</p>
<pre><code><controls:ShowCapLockWarningControler Grid.Row="1" Grid.Column="2" Style="{DynamicResource CaplockWarning}">
<PasswordBox Width="150" Name="PasswordBox" PasswordChanged="HandlePasswordChanged" VerticalContentAlignment="Center"
KeyDown="HandlePasswordBoxEnterPressed"/>
</controls:ShowCapLockWarningControler>
</code></pre>
<p>The style in the style dictionary:</p>
<pre><code><Style x:Key="CaplockWarning" TargetType="{x:Type controls:ShowCapLockWarningControler}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type controls:ShowCapLockWarningControler}">
<Grid>
<ContentPresenter Name="Presenter"/>
<Popup Placement="Bottom" PlacementTarget="{Binding ElementName=Presenter}" Name="BalloonPopup" AllowsTransparency="True"
IsOpen="{TemplateBinding ShowMessage}" >
<!-- Visual of the popup-->
</Popup>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Java Applet Grid Game Flashing On Refresh/Keypress
|
<p>I made a simple game on a grid in java that involves controlling a white square with the WASD keys. Whenever I press W,S,A, or D, the screen sometimes flickers before drawing the grid again. I am fairly new to coding, so the more you can dumb it down for me, the better.</p>

/**

*
* A simple game where the player controls a white circle with the WASD keys.
* - If the user moves his circle over a green circle, his score will go up by 1, and another red circle will spawn.
* - If the user moves his circle over a red circle, his score will go down by 1, and one less red circle will be generated.
* - There is no win condition, it is just a test game.

rails : gmaps4rails gem not showing sidebar after deployment
|
<p>I have a really tiny problem that is a huge feature for the site.
Just a quick overview I developed the rails app in development mode and used the gmaps4rails app which worked fine. However I deployed the app to Heroku and now the gmaps4rails does not show the sidebar.</p>
<p>Below is an image of how it should look like:
<a href="http://i.stack.imgur.com/UJQ1X.png" rel="nofollow">image</a>
So when the user clicks on any of the sidebar entries it takes the user to the correct marker on the map.</p>
<p>Below is an image of how it is rendered in production/Heroku
<a href="http://i.stack.imgur.com/vlNzU.png" rel="nofollow">image</a>
As you can see there is no sidebar entries.</p>
<p>Upon looking at the source code which is rendered there is one difference.
In the development mode this line of code is present <code>Gmaps.map.markers_conf.list_container = "ranchlist";</code> This code is the code that gets the list and displays it.</p>
<p>Below is the code for the view itself:</p>
<pre><code><div id="mapscontainer">
<%= gmaps("markers" => {"data" => @json, "options" => {"list_container" => "ranchlist"}},
:map_options => {"auto_adjust" => true, "zoom" => 17,
:raw => '{
panControl: true,
zoomControl: true,
mapTypeControl: false,
scaleControl: false,
streetViewControl: false,
overviewMapControl: false,
scrollwheel: false,
zoom: 20,
}'
},
:markers => { :data => @json }
)%>
<div id="ranchcontainer">
<ul id="ranchlist"><h2>Find A Mash's Wing Ranch <span style="font-size:25px;"><sup>&reg;</sup></span></h2>
<h1>Near You</h1></br>
<%= image_tag("locations/locations_line.png", :class => "lineseperator") %>
</ul>
</div>

<p>i need a dataframe with the different cell entries and that when there are two clubs, I have both clubs in the same dataframe cell Juventus Turin / Borussia Dortmund.
Otherwise I have a problem, that the code returns lists from different lenght, respectively not everything fits togehter in a dataframe.</p>
<p>I already tried it with if loops to indicate that if there are two img in one cell etc. but did not succeed.</p>
<p>Thank you very much.</p>

how to resolve the problem that hovering mouse on chart will appear old data/charts?
|
<p>I used react hooks useEffect for rendering a chart from chart.js to canvas. However, I found problem of old chart showing when I hover my mouse on the chart. From the sources I found online I realized the problem might be able to solve by chart.destroy(), but I just do not know where and how to use it in my case of code. I have attached a snip of my code here, hope anybody can help me out.</p>
<pre><code>import React, { useEffect } from 'react';

const lastSevenDays = Array(7)
.fill()
.map((_, i) => {
const localdate = localDateTime(store);
return localdate()
.subtract(i, 'day')
.format('YYYY-MM-DD[T]07:00:00[Z]');

How to add several fields in a module that belong to two tables in the same form or other - Prestashop 1.7
|
<p>I have followed the steps of a tutorial to create a module to edit invoices specifically this:
<a href="https://blog.floriancourgey.com/2018/04/edit-your-invoices-in-prestashop" rel="nofollow noreferrer">https://blog.floriancourgey.com/2018/04/edit-your-invoices-in-prestashop</a></p>
<p>But the module only allows updating the information of the fields that appear in a single table.</p>
<p>The thing is, I need to add a new field that belongs to another table and is saved in both tables.
The table that stores the module information is ps_order_invoice and the table that I also want to save, a single invoice_number field, is ps_orders.</p>
<pre><code> class AdminCustomInvoicesController extends ModuleAdminController {
public function __construct(){
parent::__construct();
$this->bootstrap = true; // use Bootstrap CSS
$this->table = 'order_invoice'; // SQL table name, will be prefixed with _DB_PREFIX_
$this->identifier = 'id_order_invoice'; // SQL column to be used as primary key
$this->className = 'OrderInvoice'; // PHP class name
$this->allow_export = true; // allow export in CSV, XLS..
$this->_orderBy = 'date_add'; // default SQL ORDER BY
$this->page_header_toolbar_title = 'Invoices'; // toolbar title
$this->_select = 'concat(upper(c.lastname), " ", c.firstname) as customer';
$this->_join = '
JOIN '._DB_PREFIX_.'orders o ON (o.id_order = a.id_orderes)
JOIN '._DB_PREFIX_.'customer c ON (c.id_customer = o.id_customer)
';
$this->fields_list = [
'id_order_invoice' => ['title' => $this->trans('ID', [], 'Admin.Global'),'class' => 'fixed-width-xs'],
'number' => ['title' => $this->trans('Number', [], 'Admin.Global'),'class' => 'fixed-width-xs'],
//I want add this new field(invoice_number) in another table ps_orders
'invoice_number' => ['title' => $this->trans('Invoice Number', [], 'Admin.Global'),'class' => 'fixed-width-xs'],
'date_add' => ['title' => $this->trans('Date', [], 'Admin.Global'), 'type'=>'datetime'],
'customer' => ['title' => $this->trans('Customer', [], 'Admin.Global')],
'total_products_wt' => ['title' => $this->trans('Total products', [], 'Admin.Global'),
'align' => 'text-right',
'type' => 'price',
],
'total_shipping_tax_incl' => ['title' => $this->trans('Total shipping', [], 'Admin.Global'),
'align' => 'text-right',
'type' => 'price',
],
'total_paid_tax_incl' => ['title' => $this->trans('Total paid', [], 'Admin.Global'),
'align' => 'text-right',
'type' => 'price',
],
];
</code></pre>
<p>I have also added in field_list</p>
<pre><code>$this->fields_form = [
'legend' => ['title' => $this->l('Custom Invoice'),'icon' => 'icon-list-ul'],
'input' => [
['name' => 'date_add','type' => 'datetime','label' => 'Date add',],
['name'=>'number','type'=>'text','required' => true,'label' => 'Number',],
//Here I add new field from ps_orders
['name'=>'invoice_number','type'=>'text','required' => true,'label' => 'Invoice number',],
['name'=>'note','type'=>'textarea','label' => 'Note',],
['name'=>'delivery_number','type'=>'text','label'=>'Delivery number'],
['name'=>'delivery_date','type'=>'datetime','label'=>'Delivery date'],
['name'=>'total_discount_tax_excl','type'=>'text','label'=>'Total amount of discounts (no tax)'],
['name'=>'total_discount_tax_incl','type'=>'text','label'=>'Total amount of discounts (with tax)'],
['name'=>'total_shipping_tax_excl','type'=>'text','label'=>'Total cost of shipping (no tax)'],
['name'=>'total_shipping_tax_incl','type'=>'text','label'=>'Total cost of shipping (with tax)'],
['name'=>'total_products','type'=>'text','label'=>'Total cost of products (no tax)'],
['name'=>'total_products_wt','type'=>'text','label'=>'Total cost of products (with tax)'],

],
'submit' => ['title' => $this->trans('Save', [], 'Admin.Actions'),]
];

<p>How can I add the invoice_number field to this module so that it updates in the table ps_orders when I put the data and at the same time the rest of the things that the module does?</p>

<p>Here is current map I display:
<a href="https://i.stack.imgur.com/5auZW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5auZW.png" alt="enter image description here" /></a></p>
<p>I use above two functions to create map below.
Right now it only displays the blue line for route 0, I would like to have blue line for all the routes.
I am trying to use directionsDisplay.setRouteIndex(i); in the for loop, but this will only display blue line for the last route. Thanks for any help!</p>

while loop issues in expect script
|
<p>I have written a expect script which works as follows:</p>
<ol>
<li>ssh to server1 </li>
<li>From server1 ssh to another server server2</li>
<li>From server2 to server3 and then sudo into a user and run the commands.</li>
</ol>
<p>In the script I read the hostnames and commands to be executed from two files called hostnames.out and commands.out. I used a while loop to iterate through each entries in hostnames.out and run the commands from the commands.out file. </p>
<p>I tested my script with single entry in the hostnames.out it works fine, but when i add multiple lines it is not running the commands on the hostnames from the second line onwards.</p>
<p>The format of the commands.out file is(one command per line):</p>
<pre>
ls -lrt
hostname
whoami
</pre>
<p>The format of the hostnames.out file is:</p>
<pre>
server1 user password server2 user password server3 user password
</pre>
<p>I have attached the script for reference. Please let me know where the problem is.</p>

Iterate json with multiple values per key for matching pattern: Set dataframe column value depending on value of other column (Faster Python Solution)
|
<p>Below is the Problem statement.</p>
<p><strong>Inputs: -</strong></p>
<ol>
<li>csv containing Time when a particular URL is hit.</li>
<li>json containing multiple url_categories with the matching url patters for each url_categories.</li>
</ol>
<p><strong>Required Output: -</strong>
csv, containing Time, url, and url_category. Where url_category is decided based on URL of input csv and url_patterns mentioned per url_category. If the URL doesn't match any of the patterns then category should be marked as 'Other'.</p>
<p><strong>Objective: -</strong>
Python code should create the required output is a FAST way.</p>
<p>Input csv (simplified) which contains the time when a particular URL is hit, like below.</p>
<pre><code>TIME,URL
11:51,/url3a/partC
12:51,/url6/partA
13:51,/url7/partA/partA/partB
14:51,/url5/partA/partB/part1
15:51,/url3b/partA
16:51,/url8/partA/partB
17:51,/url2a/
18:51,/url5/partA/partB
19:51,/url1/part1/part2
20:51,/url4b/partA
21:51,/url9/partA/partA/partB

01:51,/url9/partA/partA/partB
02:51,/url4a/
03:51,/url5b/partA/partE
04:51,/url7/partA/partA/partB
05:51,/url1b/part1
</code></pre>
<p>Input json (simplified) describing URL categories with URL patterns, like below.</p>
<pre><code>{
"category1": [ "/url1/part1/part2", "/url1a/", "/url1b/part1" ],
"category2": [ "/url2/partA/partB", "/url2a/", "/url2b/partA" ],
"category3": [ "/url3/partA/partB", "/url3a/", "/url3b/partA" ],
"category4": [ "/url4/partA/partB", "/url4a/", "/url4b/partA" ],
"category5": [ "/url5/partA/partB", "/url5a/", "/url5b/partA" ],
}
</code></pre>
<p>I have a python code which achieves but it is very slow as I'm iterating through each dataframe row and each key & values in the json. <strong>Need a solution which in which the code executes much faster</strong>, as my input csv has many rows and input json also has many url categories and many url patterns associated with each url category.</p>
<pre><code>json1 = '{"category1": ["/url1/part1/part2", "/url1a/", "/url1b/part1"], "category2": ["/url2/partA/partB", "/url2a/", "/url2b/partA"], "category3": ["/url3/partA/partB", "/url3a/", "/url3b/partA"], "category4": ["/url4/partA/partB", "/url4a/", "/url4b/partA"], "category5": ["/url5/partA/partB", "/url5a/", "/url5b/partA"]}'
print(json1)
json2 = json.loads(json1)
print(f"---json2: {json2}; \ntype(json2): {type(json2)}")
df = pd.read_csv(in_csv_path)
print(df)
for i in range(len(df)) :
for key in json2:
for url_pattern in json2[key]:
if str(df.loc[i, "URL"]).find(str(url_pattern)) != -1:
df.loc[i, "CATEGORY"] = key
df.fillna('Other', inplace=True)
print(df)
df.to_csv(out_csv, index=False)
</code></pre>
<p>Below is the output csv.</p>
<pre><code>TIME,URL,CATEGORY
11:51,/url3a/partC ,category3
12:51,/url6/partA,Other
13:51,/url7/partA/partA/partB,Other

ADO.Net retrieving autoincrement values for MS Access database in strongly typed DataSets
|
<p>I write a database client application in C# using MS Access as a DB server.</p>
<p>Users insert new rows using a <code>DataGridView</code>. I need to retrieve autoincrement values of the inserted rows on </p>
<pre><code>this.MyTableTableAdapter.Update(MyDataSet.MyTable)
</code></pre>
<p>operation.</p>
<p>I can't use </p>
<pre><code>this.MyTableTableAdapter.Fill(MyDataSet.MyTable);
</code></pre>
<p>after update operation to refresh the entire table, because the position of required inserted record is lost.</p>
<p>So I read <code>docs.microsoft.com</code>, section "Retrieving Identity or Autonumber Values":</p>
<p><a href="https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/retrieving-identity-or-autonumber-values" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/retrieving-identity-or-autonumber-values</a></p>
<p>to understand how to do it.</p>
<p>They write a vague description about it:</p>
<blockquote>
<p>Some database engines, such as the Microsoft Access Jet database engine, do not support output parameters and cannot process multiple statements in a single batch. When working with the Jet database engine, you can retrieve the new AutoNumber value generated for an inserted row by executing a separate SELECT command in an event handler for the RowUpdated event of the DataAdapter.</p>
</blockquote>
<p>I also found a code that must be performed in the event</p>
<p><a href="https://www.safaribooksonline.com/library/view/adonet-cookbook/0596004397/ch04s04.html" rel="nofollow noreferrer">https://www.safaribooksonline.com/library/view/adonet-cookbook/0596004397/ch04s04.html</a></p>
<pre><code>private void OnRowUpdated(object Sender, OleDbRowUpdatedEventArgs args)
{
// Retrieve autonumber value for inserts only.
if(args.StatementType == StatementType.Insert)
{
// SQL command to retrieve the identity value created
OleDbCommand cmd = new OleDbCommand("SELECT @@IDENTITY", da.SelectCommand.Connection);
// Store the new identity value to the CategoryID in the table.
args.Row[CATEGORYID_FIELD] = (int)cmd.ExecuteScalar( );
}
}
</code></pre>
<p>The problem is that VS IDE designer creates strongly typed DataSet without external visibility of DataAdapter object.</p>
<p>It creates TableAdapter that is inherited from Component but not from DataAdapter.</p>
<p>And although it creates a real DataAdapter inside the myTableTableAdapter class, it have protected level.</p>
<pre><code>protected internal global::System.Data.OleDb.OleDbDataAdapter Adapter
</code></pre>
<p>So I can't add any event to the Adapter outside the class myTableTableAdapter.</p>
<p>I assume that the code should be written inside the myTableTableAdapter class
but the code of this class is autogenerated, and file have next comment</p>
<pre><code>//------------------------------------------------------------------------------
// <auto-generated>
// This code was generated by a tool.
// Runtime Version:4.0.30319.42000
//
// Changes to this file may cause incorrect behavior and will be lost if
// the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------
</code></pre>
<p>So my custom code could be lost if I add any changes.</p>
<p>So my question is - How to add RowUpdated event for the DataAdapter in strongly typed DataSets?</p>

sql clr c# function to make rest api call

I have searched a lot and found the following code, but this returns data in a full page format where as I want only data in xml format so that I can process it in SQL Server. Also I am passing an url and username password which is Ok, how can I add more parameters to this?</p>

<p>My goal is to extend Vuetify locals under VueI18n as answered here: <a href="https://stackoverflow.com/questions/59821458/use-both-vuetify-and-vue-i18n-translations">Use both Vuetify and Vue-i18n translations</a>.</p>
<p>If I move the VueI18n definition and pass it to Vue constructor, this works. </p>
<p>What is the preferred way to configure this functionality? </p>

Hover on column and rows, with multiple background colors
|
<p>I know this can be done with rows, but I haven't been able to make it also work for columns. I need to be able to color code my columns, but keep the same hover color across all columns. Below is the code I have so far, I need to color the background on the 1st column grey, and leave everything else the same white. While keeping the same hover color across all rows and columns. Hope that makes sense!</p>

Neural network is not being trained, cross-entropy stays about the same
|
<p>I have written the following multilayer perceptron model in TensorFlow, but it is not training. The accuracy stays around 9%, which is equivalent to random guessing, and cross-entropy stay around 2.56 and does not vary much.</p>
<p>The architecture is as follows:</p>
<pre><code>def create_model(fingerprint_input, model_settings, is_training):
if is_training:
dropout_prob = tf.placeholder(tf.float32, name='dropout_prob')
fingerprint_size = model_settings['fingerprint_size']
label_count = model_settings['label_count']
weights_1 = tf.Variable(tf.truncated_normal([fingerprint_size, 128], stddev=0.001))
weights_2 = tf.Variable(tf.truncated_normal([128, 128], stddev=0.001))
weights_3 = tf.Variable(tf.truncated_normal([128, 128], stddev=0.001))
weights_out = tf.Variable(tf.truncated_normal([128, label_count], stddev=0.001))
bias_1 = tf.Variable(tf.zeros([128]))
bias_2 = tf.Variable(tf.zeros([128]))
bias_3 = tf.Variable(tf.zeros([128]))
bias_out = tf.Variable(tf.zeros([label_count]))
layer_1 = tf.matmul(fingerprint_input, weights_1) + bias_1
layer_1 = tf.nn.relu(layer_1)
layer_2 = tf.matmul(layer_1, weights_2) + bias_2
layer_2 = tf.nn.relu(layer_2)
layer_3 = tf.matmul(layer_2, weights_3) + bias_3
layer_3 = tf.nn.relu(layer_3)
logits = tf.matmul(layer_3, weights_out) + bias_out
if is_training:
return logits, dropout_prob
else:
return logits
</code></pre>
<p>It takes the input size as <code>fingerprint_size</code> and the labels size as well as <code>label_count</code>. It has three hidden layers with 128 neurons each. I'm following the TensorFlow example on a speech data set, which provides a framework for everything else. In the documentation, all I needed to do is to include my own neural network architecture and my method should have those arguments defined and return the logits.</p>
<p>When I trained another predefined architecture, with the same inputs and output, the neural network trains. But this one is not training. Here is one predefined architecture:</p>
<pre><code>def create_single_fc_model(fingerprint_input, model_settings, is_training):
if is_training:
dropout_prob = tf.placeholder(tf.float32, name='dropout_prob')
fingerprint_size = model_settings['fingerprint_size']
label_count = model_settings['label_count']
weights = tf.Variable(
tf.truncated_normal([fingerprint_size, label_count], stddev=0.001))
bias = tf.Variable(tf.zeros([label_count]))
logits = tf.matmul(fingerprint_input, weights) + bias
if is_training:
return logits, dropout_prob
else:
return logits
</code></pre>
<p>The learning rate are 0.001 for the first 15000 steps and 0.0001 for the last 3000 steps. These are the defaults. I also tried with 0.01 and 0.001, but the same result. I think the problem is somewhere in the above implementation.</p>
<p>Any idea?</p>
<p>Thank you in advance!</p>

How can I create a 50/50 vertical layout with stacked GridViews?
|
<p>One of my DialogFragments implements two equal-sized GridViews, one stacked on top of the other. Ideally, my layout would look like this (as seen in Android Studio):
<img src="https://i.stack.imgur.com/Hn433.png" alt="The layout as seen in Android Studio"></p>
<p>Unfortunately, when I load up the layout on an actual Android device, I get something like this:
<img src="https://i.stack.imgur.com/lE0F7.png" alt="The same layout on Android"></p>
<p>When the <strong>Kanji</strong> GridView is empty, it's completely invisible. Additionally, its height varies depending on the number of elements it has to display. How can I force the bottom GridView to fill 50% of the height as per the layout seen in Android Studio, even when it's empty?</p>
<p>Here is the XML for this particular layout:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout

Unpermitted parameters in Rails strong params from related Model on create

<p>I'm using a form in Rails to create an instance of one Model and create a join table to another model on create. In my <code>Accounts</code> controller, after verifying the new instance of <code>Account</code> has been created, I create a new join table based on checkboxes chosen in the form from another model. </p>
<p>Here is my code: </p>
<p>Models: </p>
<pre><code>class Account < ApplicationRecord

<pre><code>class Authorization < ApplicationRecord
has_many :account_authorizations
has_many :accounts, through: :account_authorizations
end
</code></pre>
<pre><code>class AccountAuthorization < ApplicationRecord
belongs_to :account
belongs_to :authorization
end
</code></pre>
<p>My <code>Accounts</code> controller: </p>
<pre><code>class AccountsController < ApplicationController
before_action :find_account, only: [:show, :update, :destroy]
def index
@accounts = Account.all
end
def show
end
def new
@authorizations = Authorization.all

def create
byebug
@account = Account.new(account_params)

authorization_ids = params.permit![:authorization][:ids]

cant upload to datastore in ckan 2.5.1: using postgres user instead of configured one
|
<p>I followed the instructions to install ckan as a package on Ubuntu 12.04 LTS. </p>
<p>I also configured the datastore extension. The databases have been created and the default users and passwords have been configured in /etc/ckan/default/production.ini</p>
<p>My problem is that every time I want to upload a dataset to the DataStore (using the button "Upload to DataStore") it first seems that everything works fine. But if I click somewhere else and click on the DataStore again I get the following red error box:</p>
<blockquote>

<p>So my problem is that for some reason I don't know ckan tries to connect to the postgres database with the postgres user.</p>
<p>My production.ini instead looks like this:</p>
<pre><code>## Database Settings
sqlalchemy.url = postgresql://ckan_default:xxx@localhost/ckan_default
ckan.datastore.write_url = postgresql://ckan_default:xxx@localhost/datastore_default
ckan.datastore.read_url = postgresql://datastore_default:xxx@localhost/datastore_default
</code></pre>
<p>There is no reference to the default database admin user in this file. The role "ckan_default" has CREATE/TEMP/CONNECT privileges and "datastore_default" has CONNECT privileges on the datastore_default database.</p>
<p>I don't see any access constraints here. Can somebody help me to solve this issue?</p>

Laravel 4, Eloquents pagination method
|
<p>Hello! I am having a problem when trying to use the paginate method on an eloquent model. The problem being that calling <code>{{ $model->links() }}</code> in my view file will throw me a <code>Call to undefined method Illuminate\Database\Query\Builder::links()</code> which didn't really get me anywhere due to it working perfectly on another view file.</p>
<p>Controller.php</p>
<pre><code>$data = Routine::whereHas('measurements', function($q)
{
$fra = str_replace("/","-", Input::get('fraDato'));
$fra = date('Y-m-d', strtotime($fra));
$til = str_replace("/","-", Input::get('tilDato'));
$til = date('Y-m-d', strtotime($til));
$q->whereBetween('date', array($fra, $til));
})->with('emps')->orderBy('date', 'time', 'title')->paginate(5);
return View::make('sok')
->with('title', 'Søk')
->with('date', $date)
->with('data', $data);
</code></pre>
<p>sok.blade.php</p>
<pre><code>@if(isset($data))

Trying to add a JComboBox dropdown into a JTextField area

<p>I have spent many hours digging around the web and cannot seem to find a straightforward answer or method to add a dropdown selection into my main panel that houses the various text fields, in this case, I am trying to add a paint color selection to the panel so that color can then be used as a variable in determining cost.</p>

decompression error while putting together parts with macHacha
|
<p>OK I have app for iPad that reads magazines. All previous issues works fine. I manage to make new issue (before it was done by other guy that left the firm) and to run it in simulator and on device without problems.</p>
<p>Now I add row for new issue of magazine in database and compress all pictures and multimedia by ZIP tool and divide them by MacHacha (because Java class that uploads demand parts from MacHacha to upload one by one) and upload it on server. In App store I downloaded magazine and can see new issue. On server new row is good have all good parameters and the size is adequate to size on disk. </p>
<p>When new issue finnish download it shows me error. I tried same procedure from simulator and in OUTPUT in the moment it crashes shows me decompression error (0).</p>
<p>I supposed that problem is with putting parts together with MacHacha. Can anyone help or give me that catch that solves this problem.</p>
<p>if it will help I can upload new issue and provide link (it's free) I it will be helpful for You guys and girls :)</p>

Merging multiple csvs the right way in panda
|
<p>I have been trying to work out how to combine several (variable amount of) csvs that all contain one same column and column data in Python. I have been looking at panda and have had only a limited success using merge, join or concat. My closest attempt was with concat (see code below). This brought together all the data but added the common field each time.</p>
<p>So I would have for example:</p>
<p>csv1</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Food</th>
<th>Type</th>
</tr>
</thead>
<tbody>
<tr>
<td>Apple</td>
<td>Fruit</td>
</tr>
<tr>
<td>Brocolli</td>
<td>Veg</td>
</tr>
<tr>
<td>Milk</td>
<td>Drink</td>
</tr>
</tbody>
</table>
</div>
<p>csv2</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Food</th>
<th>Location</th>
</tr>
</thead>
<tbody>
<tr>
<td>Apple</td>
<td>UK</td>
</tr>
<tr>
<td>Brocolli</td>
<td>Spain</td>
</tr>
<tr>
<td>Milk</td>
<td>US</td>
</tr>
</tbody>
</table>
</div>
<p>Desired result csv:</p>
<div class="s-table-container">
<table class="s-table">

</tr>
<tr>
<td>Brocolli</td>
<td>Veg</td>

</tr>
<tr>

</tr>
</tbody>
</table>
</div>
<p>Current result (with code below):</p>
<div class="s-table-container">

Why base64 image in SVG cannot be shown in Adobe Illustrator?
|
<p>I created an SVG: a grey rectangle filled with <code><pattern></code>. The icons in the pattern are <code><image></code> with base64 svg image. I then saved this svg as a .svg file with my code.</p>
<p>I found the .svg I got can be correctly shown in the browser.
However, when I used Adobe Illustrator to open this .svg, the icons disappeared, only the background grey rectangle can be shown correctly. I also tried another design tool, Figma, which showed the same result as Adobe Illustrator -- only background.
But I can open this .svg correctly in <a href="https://editor.method.ac/" rel="nofollow noreferrer">an online SVG editor</a>.</p>
<p>Do you know why it is like this, or how to download this svg and correctly show it in Adobe Illustrator?</p>
<p>Thank you in advance.</p>
<p>My code:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

Class not serializable exception when creatin an inner class in java
|
<p>My code is similar to this thread.
<a href="https://stackoverflow.com/questions/6662529/class-not-serializable-after-methods-are-overridden?newreg=89e2c3fc5b4541b6ad23d7a76ae54b62">Class not serializable after methods are overridden</a></p>
<p>But my goal is to send a method to be processed on another computer.
So, i created this class which exists on both ends. When i'm about to serialize the class, i override the method just as shown in above thread, i get the non serializable exception.
I saw in the above thread that i must create a static inner class. How can i do this?! An anonymus inner class cant be static!
And if i explicit the class name, i'll have a problem on the de-serialization end of the application.</p>
<p>Client Code:</p>
<pre><code>public static void main(String[] args) {
try {
// TODO code application logic here
Socket client = new Socket("192.168.25.22", 62222);
System.out.println("Cliente conectado");
ObjectInputStream input = new ObjectInputStream(client.getInputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
try {
Task t =(Task) input.readUnshared();
System.out.println("Objeto recebido...");
t.myTask();
System.out.println("ok");
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
} catch (Exception ex) {
System.out.println("ERRO!");
ex.printStackTrace();
}
}
</code></pre>
<p>Server Code:</p>
<pre><code>public static void main(String args[]) {
try {
ServerSocket server = new ServerSocket(62222);
System.out.println("Listening on 62222...");
Socket client = server.accept();
System.out.println("New client connected with IP: " + client.getInetAddress().getHostAddress());
Task t = new Task(null){@Override public void myTask(){System.out.println("Olá");}};
//Task tz = new Tsk(null);
ObjectOutputStream output;
output = new ObjectOutputStream(client.getOutputStream());
output.writeUnshared(t);
output.close();
System.out.println("Task created");
System.out.println("Objeto enviado.");
} catch (Exception ex) {
ex.printStackTrace();
}
}
</code></pre>
<p>Task Class Code:</p>
<pre><code> public class Task implements Serializable{
List<Object> dataImput;
List<Object> dataOutput;
boolean finished;
private static final long serialVersionUID = 595012310163575L;
public Task(List<Object> dataImput){
this.finished=false;
this.dataImput= dataImput;
}
public void myTask(){
System.out.println("Not Implemented.");
}
public boolean isFinished() {
return finished;
}

How to pass state from parent to child as props then from that child to it s child as props in React.js
|
<p>For now everything is static data .</p>
<p><strong>I have a parent sate: an array containing 4 objects
like so :</strong></p>
<pre><code> function App(){
const [searchResults,setSearchResults] =
useState([
{
name: 'name1',
artist: 'artist1',
album: 'album1',
id: 1
},
{
name: 'name2',
artist: 'artist2',
album: 'album2',
id: 2
},
{
name: 'name3',
artist: 'artist3',
album: 'album3',
id: 3
},
{
name: 'name4',
artist: 'artist4',
album: 'album4',
id: 4
}
]);
</code></pre>
<p><strong>i pass this state to the child in the return with this it works as expected :</strong></p>
<pre><code>return (
<SearchResults searchResults = {searchResults} />
)
</code></pre>
<p><strong>and from i pass it to :</strong></p>
<pre><code>import React,{useEffect,useState} from "react";
import './SearchResults.css';
import TrackList from '../TrackList/TrackList';
export default function SearchResults({searchResults}) {
return (
<div className="SearchResults">
<h2>Results</h2>
<TrackList tracks = {searchResults} />
</div>
)
}
</code></pre>
<p>now is where things got me confused.</p>
<p><strong>i try to map the data from the array to the child of this component like this(this is the whole component) :</strong></p>
<pre><code>import React,{useEffect,useState} from "react";
import './TrackList.css';
import Track from '../Track/Track'
export default function TrackList(props) {
return(
<div className="TrackList">
{
props.tracks.map( track => {
<Track track = {track} key = {track.id} />
})
}
</div>
)
}
</code></pre>
<p><strong>and i get this error with the local server displaying a white screen</strong>
[1]: <a href="https://i.stack.imgur.com/5niRQ.png" rel="nofollow noreferrer">https://i.stack.imgur.com/5niRQ.png</a></p>
<ul>
<li>i tried destructuring and assigning props value to a variable before mapping but didn't work .</li>
<li>also when i remove the .map i can see that has a props with expected data in it using react dev tools .</li>
</ul>

Microsoft.Azure.Mobile Client - Handling Server Error using custom IMobileServiceSyncHandler - Xamarin Forms
|
<p>I have implemented the Azure - Offline Sync based on the documentation / Sample provided by Microsoft <a href="https://github.com/Azure/azure-mobile-apps-quickstarts/blob/master/client/xamarin.forms/ZUMOAPPNAME/TodoItemManager.cs" rel="nofollow noreferrer">Sample</a> in my Xamarin Forms Application.</p>
<p>In the sample / documentation provided, they are using the default Service Handler.</p>
<p><strong>// Simple error/conflict handling. A real application would handle the various errors like network conditions,server conflicts and others via the IMobileServiceSyncHandler.</strong> </p>
<p>Since I need to implement a <strong>retry logic for 3 times</strong> if the <strong>Pull / Push fails.</strong> As per the documentation I have created a custom Service Handler(<strong>IMobileServiceSyncHandler</strong>).</p>
<p><strong>Please find my code logic here.</strong></p>
<pre><code>public class CustomSyncHandler : IMobileServiceSyncHandler
{
public async Task<JObject> ExecuteTableOperationAsync(IMobileServiceTableOperation operation)
{
MobileServiceInvalidOperationException error = null;
Func<Task<JObject>> tryExecuteAsync = operation.ExecuteAsync;
int retryCount = 3;
for (int i = 0; i < retryCount; i++)
{
try
{
error = null;
var result = await tryExecuteAsync();
return result;
}
catch (MobileServiceConflictException e)
{
error = e;
}
catch (MobileServicePreconditionFailedException e)
{
error = e;
}
catch (MobileServiceInvalidOperationException e)
{
error = e;
}
catch (Exception e)
{
throw e;
}
if (error != null)
{
if(retryCount <=3) continue;
else
{
//Need to implement
//Update failed, reverting to server's copy.
}
}
}
return null;
}
public Task OnPushCompleteAsync(MobileServicePushCompletionResult result)
{
return Task.FromResult(0);
}
}
</code></pre>
<p>But I am not sure how to handle / revert <strong>server copy in case all the 3 retry failed.</strong></p>
<p>In the TODO sample they where <strong>reverting</strong> it based on the
<strong>MobileServicePushFailedException</strong>. But which is available when we implement <strong>IMobileServiceSyncHandler</strong>.
More over if we include custom IMobileServiceSyncHandler it wont execute the code after <strong>PushAsync / PullAsync</strong>. Even the try catch wont fire in case any exception.</p>
<pre><code> try
{
await this.client.SyncContext.PushAsync();
await this.todoTable.PullAsync(
//The first parameter is a query name that is used internally by the client SDK to implement incremental sync.
//Use a different query name for each unique query in your program
"allTodoItems",
this.todoTable.CreateQuery());
}
catch (MobileServicePushFailedException exc)
{
if (exc.PushResult != null)
{
syncErrors = exc.PushResult.Errors;
}
}
// Simple error/conflict handling. A real application would handle the various errors like network conditions,
// server conflicts and others via the IMobileServiceSyncHandler.
if (syncErrors != null)
{
foreach (var error in syncErrors)
{
if (error.OperationKind == MobileServiceTableOperationKind.Update && error.Result != null)
{
//Update failed, reverting to server's copy.
await error.CancelAndUpdateItemAsync(error.Result);
}
else
{
// Discard local change.
await error.CancelAndDiscardItemAsync();
}
Debug.WriteLine(@"Error executing sync operation. Item: {0} ({1}). Operation discarded.", error.TableName, error.Item["id"]);
}
}
}
</code></pre>
<p><strong>Note</strong></p>
<p>In my application I am only trying to achieve retry for 3 time in case any server error. I am not looking for to resolve conflicts. Thant is the reason I haven't added the code for the same.</p>
<p>If someone came across similar issues and resolved it please help.</p>
<p>Stez.</p>

<p>When I click on the <code>checkbox</code> and the value of that row changes or when i add a new workout and the table changes i want it to change color... I don't know how to proceed. </p>
<p>Please help me :)</p>
<p>I think it could be something like this: <code>$('#TblWorkouts input').on('change'</code> but I'm don't know. </p>
<p>Jag har en uppgift att lämna in där ett krav är att när en rad i tabellen ändras ska den få en annan färg men jag vet inte hur jag ska gå till väga.</p>

Python and Webkit, watching serial port thread, how to avoid core dump running javascript
|
<p>I'm writing a game that uses python and webkit, and a webpage is the front-end/GUI. The PC is connected to an Arduino that controls a coin hopper and other i/o. When the Arduino sends 'coinin' over serial, I capture this in a serial-watching thread, then run some javascript on the webpage to 'add' a coin to the game. </p>
<p>For simplicity in troubleshooting, I set up an example that runs a test thread instead of reading serial, but the problem is the same. The thread tries to add a coin every second by running 'addcoin()' on the webpage. If you uncomment the run_javascript() line, the program core dumps. </p>
<p>I came up with a keyboard hack workaround. The test thread, instead of trying to run_javascript() directly, does an os.system call to xdotool to type the letters 'conn' to the program window. That window has a key-event listener, and when it gets the letters 'conn' in keybuffer[], it then runs the desired run_javascript() call to the webpage. If you copy the two files to a folder, and run the python program, you'll see the coin text count up every second (Hit BackSpace to end the program). If you try to run the javascript from the thread instead, you'll see the program core dump.</p>
<p>The question is, is there a better way to do this, without having to use the keyboard hack to run the javascript? Although the hack gets around the problem, it introduces a weakness in the game. You can cheat a coin in by typing 'conn' on the keyboard. I'd like to find some other way to trigger the event, without having to use the keyboard event.</p>
<p><strong>Sample webpage index.htm</strong></p>
<pre><code><html>
<script language="JavaScript" type="text/javascript">
var mycoins=0;
document.onkeydown = function(evt) {
evt = evt || window.event;
cancelKeypress = (evt.ctrlKey && evt.keyCode == 84);
return false;
};
function addcoin()
{
mycoins+=1;
id('mycoins').innerHTML="You Have "+mycoins.toString()+" coins"
}
function id(myID){return document.getElementById(myID)}
</script>
<html>

Invalid precision value writing to Oracle wth VBSript
|
<p>Since you all led me in the right direction yesterday, I'm back. I am migrating from windows 2003 to windows 2012. A couple of small, but vital, apps are written in asp (VBScript) and an Oracle 11g DB. Many of the DB calls are failing. The latest is a procedure call. I don't write VBScript so I'm struggling here. The driver is Oracle in OraClient11g_home2</p>

Read text file and name buttons VB.NET

<p>What I wan't to do is to read a text file with 1, 2, 3, 4 or 5 lines.
If the text file is completely full (5 lines) then the code works.</p>
<p>But the code needs to work when there are only 3 lines in the text file.

Is it possible to combine mapAreas from ArcGISOnline in one offline map on android?
|
<p>I try to create an offline map using ArcGIS Runtime SDK for Android 100.5.0. I follow preplanned workflow according the guide <a href="https://developers.arcgis.com/android/latest/guide/take-map-offline-preplanned.htm" rel="nofollow noreferrer">https://developers.arcgis.com/android/latest/guide/take-map-offline-preplanned.htm</a>. I create mapAreas in ArcGISOnline and try to download them from device. I want to get an offline map, which contains all mapAreas together like in app maps.me(on a big map you have downloaded regions with deeper detailing), but instead I am getting an offline map made from last downloaded area. So I created mapArea "Europe" with scale world - cities and mapArea "Berlin" with scale cities - buildings (both basemaps - openstreetmaps, no feature layers) and downloaded them successfully, see 2 tpk files in a folder, but mobile_map.mmpk and package.info files only contain data related to last loaded area. Is it possible at all to get what I want, combine tpk files in one map? </p>
<p>My code in Kotlin: </p>
<pre><code> val portal = Portal("https://www.arcgis.com/", false)
val portalItem = PortalItem(portal, itemID)
val offlineMapTask = OfflineMapTask(portalItem)
//get all of the preplanned map areas in the web map
val mapAreasFuture = offlineMapTask.preplannedMapAreasAsync
mapAreasFuture.addDoneListener {
try {
// get the list of areas
val mapAreas = mapAreasFuture.get()
val directory = getDirectory()
prepareDir(directory)
// loop through the map areas
var i = 0
for (mapArea in mapAreas) {
mapArea.loadAsync()
mapArea.addDoneLoadingListener {
val downloadJob = offlineMapTask.downloadPreplannedOfflineMap(mapArea, directory)
downloadJob.start()
downloadJob.addJobDoneListener {
i++
if (i == mapAreas.size) {
val offlineMapPackage = MobileMapPackage(path)
offlineMapPackage.addDoneLoadingListener({
if (offlineMapPackage.getLoadStatus() === LoadStatus.LOADED) {
val mobileMap = offlineMapPackage.getMaps().get(0)
myCompletionFuncToShowMap(mobileMap)
} else {
println("PACKAGING FAILED")
}
})
offlineMapPackage.loadAsync()
}
}
}
}
} catch (e: InterruptedException) {
e.printStackTrace()
} catch (e: Exception) {

<p>Hopefully you can see, but thebackground pics dont take up the whole screen, and there's a thin white border around them on the sides. The top bar and About Us bar span the whole page from the left to the right, but not the background pics.</p>

Catch Jquery UI dialog box event
|
<p>I am having an ajax call. In that ajax call I am passing a json to the server. This happens when the person clicks on the delete button. So, before deleting I am creating a Jquery UI dialog box. In that I am asking user whether he is sure to delete. </p>
<p>Now, my problem is when the user clicks I am not able to catch the event. I am assigning a variable ok to have value when yes or no is clicked in jquery dialog box. But the problem is where I am checking if (ok == 1 ) is called first before the user clicks on yes or no. So in any case if user clicks yes or no the ajax call won't happen.</p>
<p>Both the function is in different scripts file.</p>
<p>The function which does the ajax call is -</p>
<pre><code>$("#delete")
.click(
function() {
var sendData = {};
deleteClicked = 1;
var passedJSON = null;
if (null != selectedRowData) { // if the id in table is not null
if (null != selectedRowId) {
console.log("ID exists --> " + newId);
if (rowclickable == 1 ) { //checking whether row should be deleted or not
var testDate = $("#FromDate").val();
sendData["FromDateStr"] = testDate;
console.log(sendData);
passedJSON = JSON.stringify(sendData);
console.log(passedJSON);
ok = showModalBoxForDelete(ok); // calling the modal box and storing the value
console.log(ok);
if (ok == 1) {
$
.ajax({
type: "POST",
cache: false,
url: deleteURL,
data: passedJSON,
dataType: "json",
cache: false,
async: "true",
contentType: "application/json",
success: function(
data) {
if (1 == data.responseCode) {
$(
"#FromDate,delete")
.attr(
"disabled",
"disabled");
$("#FromDate").datepicker("disable");
table.ajax.reload(null, false); // To load the table
showModalBoxForSuccessfulUpdate("The Goal is Deleted");
} else {
alert(data.responseMessage);
}
},
error: function(data) {
console.log("Server Failure");
}
});
}
}
}
}
</code></pre>
<p>The function which calls the modal box is -</p>
<pre><code>function showModalBoxForDelete(ok){
$("#modelView").dialog({
autoOpen : false,
modal : true,
draggable: false,
buttons : [ {
text : "Yes",
icons : {
primary : "ui-icon-heart"
},
click : function() {
var ok = 1;
$(this).dialog("close");
return ok;
}
}, {
text : "No",
icons : {
primary : "ui-icon-heart"
},
click : function() {
$(this).dialog("close");
console.log("Retaining the page...");
}
} ]
});
$("#modelView" ).dialog("open");
$("#modelView").text("This will delete the goal. Do you still want to continue?");
return ok;
}
</code></pre>
<p>Here the line which checks <code>if (ok == 1)</code> is causing a problem as it will get run before user clicks yes or no.</p>
<p>I am not able to understand what to do now. Can anyone please help?</p>

How to enlarge tableView on scroll?
|
<p>I'm sorry if this is a duplicate. I tried to review similar questions in SO - still doesn't quite make me understand how to deal with this.</p>
<p>I have a tableView, three textViews and a UIButton. When the user scrolls the tableView, the tableView should pushes the textFields and the button out the image and take up more space. When that is done I want to continue scrolling through the cells.</p>
<p>(I want one of the textFields to always remain and still show the title.) </p>
<p>I think I need to put the textViews and button above the tableView inside a tableView header after which I need to set certain constraints between the UIView above the tableView and tableView itself. Then I need to play around with the UIScrollViewDelegate and calculate something.</p>
<p>As you guys can probably tell, I'm relatively new in programming and I believe this i why I don't quite understand the related questions. And as you can probably tell too, why I am pretty damn confused about how to solve my problem! </p>
<p>Here's a photo of the VC:
<a href="https://i.stack.imgur.com/FxIlj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FxIlj.png" alt="My-VC"></a></p>
<p>I wan't the tableView to go and cover the 'AddNewPersonBtn' and the two bottom textView - leaving only the top textView, the navigationBar and the tableView on the screen. --> Until you then scroll down again and the rest will be visible again. </p>

Swift URLSession.shared.dataTask GET Request -1001 returns timeout
|
<p>Sending a POST request to our NGINX Server works good with <code>URLRequest</code> and <code>URLSession.shared.dataTask</code>.
I can login to my app but when I try a GET request my server has no log that the request reached him. Finally I get the timeout error. Important, I am using https. I also tried to use http for GET Requests. on my NGINX Server I set TLS to 1.2 only (I am not a system specialist, I did that in the nginx cfg file. </p>
<blockquote>

<p>I am sure that my code for the <code>URLRequest</code> and <code>URLSession</code> is correct because against localhost and our development environment I do not have any of those problems.</p>
<p>Thats my code to create my <code>URLRequest</code></p>
<pre><code>private func buildUrlRequest(jsonObject:[String: Any], connectionType:ConnectionTypes, url:String) -> NSMutableURLRequest? {

<p>This is how I create the task... after the method body I am using <code>task.resume()</code></p>
<pre><code>let task = URLSession.shared.dataTask(with: request as URLRequest) { data, response, error in .... (and so on)
</code></pre>
<p>I spend more than hours to solve this problem... But I have no idea.
I am not sure if the Problem is the Server Config or the Swift code...</p>

Declaring integers in actionPerformed java
|
<p>So I'm trying to create this program in Java that's supposed to keep track of how much stock there is. Like if you wanted to cook pancakes, you would click a button that said "pancakes" and 1xmilk, 2xtimes egg would be removed from the stock every time you click the button, the problem is that I have to declare the integers inside the <code>actionPerformed()</code>, so every time I click the button the original values reset, does any kind soul have the answer? </p>
<pre><code>//1100 Button
JButton bj1100 = new JButton("1100");
f.add(bj1100);
bj1100.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
System.out.println("1100");
//1100 head menu
MAIN f = new MAIN();
f.setLayout(new FlowLayout());
//250/1100 HYDR
JButton bj250HYDR = new JButton("250/1100 HYDR");
f.add(bj250HYDR);
bj250HYDR.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
System.out.println("Building a250/110 HYDR");
//Stock
int lOmaxel =10;
int lVals = 10;
//Orderpoint
int bOmaxel =5;
int bVals = 5;
//Amount to make
int tOmaxel =10;
int tVals =10;
lOmaxel--;
lVals--;
}

Having difficulty with my Monty Hall stimulator code (python)
|
<p><strong>What the Monty Hall game is:</strong></p>
<p>The stage is set up with three large doors labeled #1, #2, and #3. Behind two of the doors is a goat. Behind the other door is a new car. You don’t know which door has the car, but Monty Hall wants you to pick a door. Suppose you pick door #1. Monty Hall then opens one of the other doors (say, door #3) and shows you that there’s a goat behind it. He then says: "I’ll give you a chance to change your mind. Do you want to change your mind and pick door number 2?" After you make a decision, they open the door you finally picked and you find out whether you’ve won a new car or a new goat. To clarify: the locations of the car and the goats are fixed before your game starts. Monty does not get a chance to switch things around in the middle of the game.</p>
<p><strong>What I have to do:</strong> </p>
<p>I need to create a stimulator of the game using Python <strong><em>3</em></strong>. I have to incorporate a random number generator. The program will ask the user for the Random Number generator seed. The goal of a random number generator is to be random. Before my program begins simulating “Let’s Make a Deal,” it's supposed to ask the user for an integer and set it as the seed. If the user gives an input that is not a number, the program should exit immediately by displaying "Seed is not a number!" IF the user gives a number for the input, the game will begin. The game will then ask the user how many games the user wants to run. If the user says 5, the game will repeat five times. Once the game runs the amount of times the user says (like 5), then the game will ask the user AGAIN how many times the user wants to play again.(I'm having difficulty with this looping the game to the number of times the user says and then asking the question once it's done). If the user says 'exit' anytime, the game immediately ends. When asked how many games the user wants to run, if the user does not input a number, the program will just say "Please enter a number" until the user finally enters a number. </p>
<p><strong>What the program has to do:</strong></p>
<p>The program will be easier because it will print the doors AND label which door has a goat or car. So it will display "G" "C" "G" where they will be shuffled for each game so if the program outputted: [C G G] the car would be in door one. Monty (in this case, Monty is just a variable) would "pick" a door where the program randomly generates a number that is either 1, 2, or 3. IF the user picks a door that has the car in it, the program will say the user should stick with the door they picked in order to win. If the user picks a door that has a goat, the program will say that the user should change the door they picked in order to pick the door with the car (I'm stuck at this part). After each set of games, the program gives a summary of how many times the player should have switched and how many times they should have stayed. If the number of games is less than or equal to 10, the program will print out the results of each game. If the result is greater than 10, it will just print the summary.</p>
<p><strong>Example</strong></p>
<p><em>If the input is:</em></p>
<p>25</p>
<p>5</p>
<p>exit</p>
<p><em>Output should be:</em></p>
<p>Enter Random Seed:</p>
<p>Welcome to Monty Hall Analysis</p>
<p>Enter 'exit' to quit.</p>
<p>How many tests should we run?</p>
<p>Game 1</p>
<p>Doors: ['G', 'C', 'G']</p>
<p>Player Selects Door 1</p>
<p>Monty Selects Door 3</p>
<p>Player should switch to win.</p>
<p>Game 2</p>
<p>Doors: ['C', 'G', 'G']</p>
<p>Player Selects Door 1</p>
<p>Monty Selects Door 2</p>
<p>Player should stay to win.</p>
<p>Game 3</p>
<p>Doors: ['G', 'C', 'G']</p>
<p>Player Selects Door 2</p>
<p>Monty Selects Door 1</p>
<p>Player should stay to win.</p>
<p>Game 4</p>
<p>Doors: ['C', 'G', 'G']</p>
<p>Player Selects Door 1</p>
<p>Monty Selects Door 2</p>
<p>Player should stay to win.</p>
<p>Game 5</p>
<p>Doors: ['G', 'C', 'G']</p>
<p>Player Selects Door 3</p>
<p>Monty Selects Door 1</p>
<p>Player should switch to win.</p>
<p>Stay Won 60.0% of the time.</p>
<p>Switch Won 40.0% of the time.</p>
<p>How many tests should we run?</p>
<p>Thank you for using this program.</p>
<p>I am a pretty beginner programmer who's trying to learn so sorry if this is confusing or does not make sense! I have a program so far and I know it's not very good. If someone could help me at all, that would be greatly appreciated. I'm very confused about the randomization aspect of it.</p>
<p><strong>Here is what my program outputs</strong></p>
<p>Enter Random Seed:</p>
<p>Welcome to Monty Hall Analysis</p>
<p>Enter exit to quit.</p>
<p>How many tests should we run?</p>
<p>Seed is not a number!</p>
<p><strong><em>Here is my program:</em></strong></p>
<pre><code>import random
random_seed = input('Enter Random Seed:\n')
try:
random_seed = int(random_seed)
print('Welcome to Monty Hall Analysis')
exit = input('Enter ''exit'' to quit.\n')
tests = int(input('How many tests should we run?\n'))
try:
tests = int(tests)
while True:
select_door = ['G', 'C', 'G']
player_door = input('Doors', random.shuffle(select_door))
doors = [1, 2, 3]
random.choice(doors)
print('Player Selects Door', select_door)
print('Monty Selects Door', random.choice(doors))
if exit == 'exit':
print('Thank you for using this program.')
break
except ValueError:
print('Please enter a number:\n')
except ValueError:
print('Seed is not a number!')

<p>I am having problems with the code to introduce data from java to a table in Mysql.</p>
<p>First I create the table if it doesn't exist:</p>

How to fix value update delay in vuejs after axios request?
|
<p>I am retrieving a list of data from an api and need to fill the specific <code><select></select></code> tags, which is associated to a few radio button, with some of the data as <code><options></options></code>. The radio buttons waiting for an event (<code>@change</code>/<code>@click</code>) and executing and axios get request. Everthing works fine. I click on a radio button and retrieving the data as response (vue tools also showing the right data) but the <code><option></option></code> tags are not updating. Now when I click on another radio button, I am getting again the right data from the api BUT now the <code><option></option></code> tags are refreshing with the data from the previous response.</p>

How do I access the $ref in the JSON recursively as to complete the whole JSON?
|
<p>I have this schema, which has <code>$ref</code> in it. I need to recursively (assuming there are no infinite cycles) fill in references. That is, wherever <code>$ref</code> is present, the whole object is replaced with what it points.</p>
<p>Note, I can't use any libraries and need to write the Class/function on my own. I did see <a href="https://github.com/gazpachoking/jsonref/blob/master/jsonref.py" rel="nofollow noreferrer">jsonref</a> but was unable to understand the LazyLoad and the callbacks.</p>
<p>Could it be done in a simpler way? I've been trying to do this for days.</p>
<pre><code>{
"definitions": {
"pet": {
"type": "object",

AngularJS and WordPress API display data from single post
|
<p>I'm using the WordPress API as a data service to an AngularJS/Ionic app. I have a post type called programmes and have a list of programmes (posts) and the JSON looks like:</p>
<pre><code>var programmes = [
{
id: 6,
title: "A post",
slug: "a-post"
},
{
id: 7,
title: "Another post",
slug: "another-post"
},
{
id: 8,
title: "Post 123",
slug: "post-123"
}
]
</code></pre>
<p>I've got the list of programmes displaying with ngRepeat. However I'm struggling to get the data for an individual post.</p>
<p>I was trying to do it like so to get data for the single programme: <code>var programme = programmes[$stateParams.programmeId];</code> however the issue is, for example, if I click on the first "A post" it returns <code>6</code> from the programme id but this does not match the index of the object which is <code>0</code>.</p>
<p>How can I get data from a single programme when the id and index do not match without having to manually reset the programme id's in the database?</p>
<p>Here are my files so far:</p>
<p><strong>app.js</strong></p>
<pre><code>.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: 'AppCtrl'
})
.state('app.programmes', {
url: "/programmes",
views: {
'menuContent': {
templateUrl: "templates/programmes.html",

}
}
})
.state('app.programme', {
url: "/programmes/:programmeSlug",
views: {
'menuContent': {
templateUrl: "templates/programme.html",
controller: 'ProgrammeCtrl'
}
}
})
$urlRouterProvider.otherwise('/app/programmes');
});
</code></pre>

<pre><code>.factory('DataFactory', function($http) {
var urlBase = 'http://event-app.dev/wp-json/wp/v2';
var APIdata = {};
var currentProgramme = null;
return {
getProgrammes: function() {
return $http.get(urlBase + '/programmes');
}
}
})
</code></pre>
<p><strong>controllers.js</strong></p>
<pre><code>.controller ('ProgrammesCtrl', function ($scope, DataFactory) {
getProgrammes();

$scope.status = 'Unable to load data';

*ngFor not showing any data
|
<p>I'm creating a chatting app. I have a slight problem, <code>ngFor</code> doesnt seem to work for me.</p>
<p>I have 2 components, 1 is the feed which holds the other component which is the message. So feed shows a list of message components.</p>
<p>Feed
.ts</p>
<pre><code>import { Component, OnInit, OnChanges } from '@angular/core';
import { Observable } from 'rxjs';
import { Message } from '../models/message';
import { MessageService } from '../core/message.service';
@Component({
selector: 'app-feed',
templateUrl: './feed.component.html',
styleUrls: ['./feed.component.css']
})
export class FeedComponent implements OnInit, OnChanges {
feed: Observable<Message[]>;
constructor(private msgService: MessageService) { }
getMessages(): Observable<Message[]> {
return this.msgService.getAllMessages();
}
ngOnInit() {
this.feed = this.getMessages();
}
ngOnChanges() {
this.feed = this.getMessages();
}
}
</code></pre>
<p>Feed .html</p>
<pre><code><div class="feed">
<div *ngIf="feed | async; then fetched else fetching">
</div>
<ng-template #fetched>
<div *ngFor="let message of feed$ | async" class="message">
<app-message [message]=message></app-message>
</div>
</ng-template>
<ng-template #fetching>
<h3>Loading...</h3>
</ng-template>
</div>
</code></pre>
<p>Message .ts</p>
<pre><code>import { Component, OnInit, Input } from '@angular/core';
import { Message } from '../models/message';
@Component({
selector: 'app-message',
templateUrl: './message.component.html',
styleUrls: ['./message.component.css']
})
export class MessageComponent implements OnInit {
@Input() message: Message;
sender: string;
body: string;
createdAt: string;
constructor() { }
ngOnInit(message = this.message) {
this.sender = message.Sender;
this.body = message.Body;
this.createdAt = message.CreatedAt;
}
}
</code></pre>
<p>Message .html</p>
<pre><code><div class="messageContainer">
<div class="messageData">
<span class="sender">
<p>{{sender}}</p>
</span>
<span class="createdAt">
<p>{{createdAt | date:'medium'}}</p>
</span>
</div>
<div class="messageContent">
{{body}}
</div>
</div>
</code></pre>
<p>Also here is my service which does an API call from my asp.net project.</p>
<p>MessageService .ts</p>
<pre><code>import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { HttpClient } from '@angular/common/http';
import { Message } from '../models/message';
@Injectable({
providedIn: 'root'
})
export class MessageService {
private readonly baseUrl = 'http://localhost:50169';
constructor(private http: HttpClient) { }
getAllMessages(): Observable<Message[]> {
return this.http.get<Message[]>(`${this.baseUrl}/api/messages`);
}
}
</code></pre>
<p>I've tried checking the value of the API call and it has value based on the console log.</p>
<p>My problem is it does not show any data on the <code>ngFor</code> of the feed component.</p>

Configuration issue in HermesJMS - java.lang.NoClassDefFoundError for BeanSupport class
|
<p>I am trying to test a message using HermesJMS. I am getting a <code>java.lang.NoClassDefFoundError</code> for the <code>BeanSupport</code> class. What could be the issue?</p>
<p>I have configured the required jars under specific path and configured the same in hermes-config.xml within the tag <code></classpathGroup></code>.
The <code>org.apache.activemq.artemis.utils.uri.BeanSupport</code> is present in <code>artemis-commons-2.0.0.jar</code> which is already included in classpathGroup which I am able to view under Options->Configuration->Providers in HermesJMS.
I have included all the required jars and configured the same.
Few blogs suggested that the version of jar might be the cause of the issue. I tried all versions of artemis-commons jar yet, I am getting the same error.
Kindly suggest your views on the issue. </p>
<p>The complete stack of the error message :</p>

No load data anymore except refresh action
|
<p>I couldn't find a solution to my problem on the search engine, So i decided to ask here.</p>
<p>I have navigation tab with 3 fragments <code>fragmentA, fragmentB, fragmentC</code>. Each fragment load data from parsed data. i have opened fragment a and load data on listview, then i want to change to fragment b, and load the data too. but when i want to go back to fragmentA the fragment loads the data again.</p>
<p>I want my fragment are saving the loaded data before and when i refresh the fragment, the fragment load new data. An example app like a twitter or facebook. What i have to do? thanks for reading</p>

Combining CSS Animations. What next?
|
<p>I am trying to make an animation of a stack of folders, where they will raise up, and then open to reveal the inside of the folder on hover (all but the bottom folder need to rise). </p>
<p>So far I have made the all top folders rise, and I've made the bottom folder open. Where I'm stuck is how to get the top folders to open after they rise. (side problem: getting both the front flap and the back of the folder to rise at the same time).</p>
<p>Here's a jsfiddle of what I have so far. Here to learn! Thanks</p>
<p><a href="https://jsfiddle.net/m4ax81r6/" rel="nofollow">https://jsfiddle.net/m4ax81r6/</a></p>
<p>Edit:
To add a little more clarification - the front and back of the folder need to rise together on hover of the front of the folder. Then the front of the folder needs to fold down, while all still risen. Last, the folder needs to fold back up and lower when the mouse stops hovering.</p>

what does this line do in this code?
|
<p>i have found following code on online for suffix tree</p>
<pre><code>#include <stdio.h>
#define E 0
struct suffix_tree_node;
struct suffix_tree_link {
// 0 is e - global index of during string's end
unsigned long start;
unsigned long end;
suffix_tree_link(suffix_tree_node* source, suffix_tree_node* target,
unsigned long start, unsigned long end) {
this->source = source;
this->target = target;
this->start = start;
this->end = end;
}
suffix_tree_node* source;
suffix_tree_node* target;
suffix_tree_link* next_link;
};
struct suffix_tree_node {
suffix_tree_link* first_link;
suffix_tree_node* parent_node;
suffix_tree_node* suffix_link_node;
// other constructors?
suffix_tree_node() {
parent_node = suffix_link_node = NULL;
first_link = NULL;
}
void add_target(unsigned long start, unsigned long end, suffix_tree_node* target) {
suffix_tree_link* link;
for(link = first_link; link != NULL; link = link->next_link);
link = new suffix_tree_link(this, target, start, end);
}
};
class suffix_tree {
suffix_tree_node* root;
const char* string;
void ukkonen() {
root->add_target(1, E, new suffix_tree_node);
unsigned long e = 1, j_i = 1, i = 1;
for( int i = 0; string[i] != '\0'; i++) {
e++;
for() {
j_star = j;
}
j_i = j_star;
}
}
public:
suffix_tree(const char* string) {
root = new suffix_tree_node();
this->string = string;
ukkonen();
}
};
int main() {
suffix_tree("foof");
return 0;
}
</code></pre>
<p>everything is clear almost in this code,because i have read about suffix tree many times before,but i did not understand this fragment:</p>
<pre><code>void ukkonen() {
root->add_target(1, E, new suffix_tree_node);
unsigned long e = 1, j_i = 1, i = 1;
for( int i = 0; string[i] != '\0'; i++) {
e++;
for() {
j_star = j;
}
j_i = j_star;
}
}
</code></pre>
<p>what does this code do?</p>
<p>also what is <code>for()</code>? or <code>j_start</code>?</p>
<p>here is <a href="https://github.com/qumon/da_labs/blob/a59083eac127aedf56b9fdfef27a0d63ce7af6bf/lab5.3.cpp" rel="nofollow">a link</a> for this code.</p>

Handling a Many-to-Many Dimension when all dimensional values have 100% importance
|
<p>I'll at least try to keep this succinct.</p>
<p>Let's suppose we're tracking the balances of accounts over time. So our fact table will have columns such as...</p>
<p><strong>Account Balance Fact Table</strong> </p>
<ul>
<li>(FK)AccountID </li>
<li>(FK)DateID</li>
<li>...</li>
<li>Balance</li>
<li>...</li>
</ul>
<p>Obviously you have an <strong>Account Dimension Table</strong> and a <strong>Date Dimension Table</strong>. So now we can easily filter on Accounts or Dates (or date ranges, etc.).</p>
<p>But here's the kicker... Accounts can belong to Groups -- any number of Groups at a given Date. Groups are simply logical abstractions, and they have no tangible meaning aside from reporting purposes. An Account being in 0, 1, or 17 groups doesn't affect its Balance in any way. For example, AccountID 1 may be in Groups 38, 76, 104, and 159. Account 2 may be in Group 1 (which has a Group Description of "Ungrouped". Account 3 may be in seventeen groups (real example).</p>
<p>As an added bonus, our users are completely non-technical. They don't know SQL, they have no experience with relational databases, and have historically done all of their work in a convoluted Excel solution. Right now we're building a dimensional model they can slice and filter with PowerPivot, though these Account Groups are threatening to turn an otherwise ruthlessly simple Star Schema into something complex enough that the users will balk and return to their current spaghetti solution.</p>
<p>So let's look at our options...</p>
<p><strong>Boolean Method</strong>
The Boolean method is not feasible. We have about 570,000 different accounts, but more importantly, 26,000 different groups. This would also be a devil for end-users to filter, since they're non-technical and are relying on very simple tools to get this done.</p>
<p><strong>Multiple Column Method</strong>
In theory this could work, however, we do have some accounts that belong to 17 groups. Again, the groups are really just logical groups -- they have no meaning, but they are required by the business for reporting purposes. Having end-users filter out groups from 17 different columns isn't going to go over well in user-acceptance, and would likely result in users refusing to use the solution (and I don't blame them).</p>
<p><strong>Bridge Table</strong>
This count work, but we do have 26,000 different groups. I'm not finding this to be user-friendly.</p>
<p>Since I'm not liking my options, I can only assume there's a better way other than snowflaking... unless snowflaking IS the only way. If someone could lend a hand and explain their rationale it'd be appreciated.</p>
<hr>
<p><strong>UPDATE:</strong> For clarification, an example I think everyone here can relate to is imagine you can list keyword skills on a resume. They all relate to the same person, but you can have any number of skills. The skills don't effect any of individual measures on a resume -- i.e. 'C++' isn't more valuable than 'C#' -- you can't put all the resume/skill combinations in the fact table or you'd end up double counting (or well more than double ;) ).</p>
<p>I think the best I'm going to be able to do here is to create an outrigger table for groups. I'm not a fan of it, but I think it's the only real option I have.</p>
<p>So now we have...</p>
<p><strong>Account Balance Fact Table</strong> </p>
<ul>
<li>(FK)AccountID </li>
<li>(FK)DateID</li>
<li>...</li>
<li>Balance</li>
<li>...</li>
</ul>
<p><strong>Account Dimension</strong></p>
<ul>
<li>(PK)AccountID</li>
<li>Account Name</li>
<li>...</li>
<li>(FK)Account Group Key</li>
</ul>
<p><strong>Account Group Outrigger</strong></p>
<ul>
<li>(PK)AccountGroupID</li>
<li>(PK)AccountID)</li>
<li>Account Group Name</li>
</ul>

Uploading a Image Works on some devices but returns Stream FixedLengthSource .inputStream()

<p>It keeps normalizing things so the intensity shows now different.
Is there any function to normalize this data?
I want the map to be darker for those with a larger value. Can anyone give me some recommendations?</p>

Loop to get model fields, create new model instances based on API returned values
|
<p>I'm using a couple of different API calls to populate (create_or_update) a particular Model's fields. Instead of having to create a new series of create_or_update fields for every API call, I am trying to make a loop to get rid of boilerplate code. There is a small caveat in the fact that some of the fields returned by the api overlap with python reserved keywords (eg id, type). I need to be able to pick those out and rename them in the dict during the looping comparison.</p>
<ol>
<li>Looks up the Model and gets its fields, creating a list of those fields eg:</li>
</ol>
<pre><code>['id', 'organizationId', 'name', ... ]
</code></pre>
<ol start="2">
<li>Cycles through the API response and creates a dictionary of key:values for each response object. If the list value is found in the dictionary, set the key: value to what is found in the API response, otherwise, set the value for the field to None. </li>
</ol>
<pre><code>{ 'id': 'N_543265', 'organizationId': '43675', *name field missing* , ...}
</code></pre>
<p>Since both 'id' and 'organizationId' are found, I want their values to be updated into the Model instance, but as 'name' is not found, I want that to be skipped</p>
<p>The main issue I am having is that when this runs (it is a celery task), it tells me the following:</p>
<blockquote>
<p>database.models.Network.DoesNotExist: Network matching query does not exist.</p>
</blockquote>
<p><strong>models.py</strong></p>
<pre class="lang-py prettyprint-override"><code>class Device(models.Model):
networkId = models.ForeignKey(Network, on_delete=models.CASCADE, blank=True, null=True, related_name='network_device')

pass
return result
</code></pre>
<p>Basically, I want my model instance to populate based on comparing fields returned in the API, to avoid throwing a KeyError, and without having a long list of try/except to manually fish out fields that may or may not exist in the API data. </p>
<p>Any assistance would be great, even if it is more high level about the way I've gone about the problem. I think a lot of people could gain from this snippet if i can get it working correctly.</p>
<p><strong><em>EDIT</em></strong></p>
<p>I managed to find a solution to this problem, so I have detailed it here for anyone interested. I have found this solution saves me a lot of headaches when importing data to the database from an API with varying fields.</p>
<p>I will use a shortened version of data returned from the Meraki dashboard API (<a href="https://dashboard.meraki.com/api_docs" rel="nofollow noreferrer">https://dashboard.meraki.com/api_docs</a>):</p>

<p>Why have an array excluding some items from the dictionary???</p>
<p><strong>'serial'</strong> - Excluded because we want to use this as our unique field to search for an object to update
<strong>'parent_network'</strong> - This is a foreign key field, so this has to be fed a 'Network' object</p>
<p>Now if we have other similar functions that have to deal with API data, we have a
bit of a template that we can copy. All we need to do to apply it to a new
set of API data is change the 'excludes' array and process any ForeignKey fields
outside of the k, v loop.</p>
<p>The next thing to do would be to turn this into a fully re-usable vanilla function
that can be passed all the required variables but unfortunately, that is out of my
range of skills. It would be great to see someone else do this if possible.</p>
<p>I hope this has been helpful. <em>Thanks for reading!</em></p>

The samples read from the AVAssetReader is not in order

create another instance 'B' after saving an instance 'A' automatically
|
<p>i'm using <code>Django 1.7</code> with <code>django_rest_framework 3.0</code> to develop a restful backend for my application.</p>
<p><strong><em>The scenario:</em></strong> On the client the user will authenticate with a social network, say facebook. The <code>token</code> is sent back to the server which creates and stores an instance of <code>Social</code> model. </p>
<p><strong><em>The need:</em></strong> On saving the <code>Social</code> model, I want to <em>automatically</em> create and store an instance of <code>django.contrib.auth.models User</code> model. The data for the <code>User</code> model will be extracted from the social network that the user just authenticated with.</p>
<p><strong><em>My approach #1:</em></strong> Is there some way where I can send a combined json request to my django backend and create independent <code>User</code> and <code>Social</code> instances. I think this would require changing the <code>serializers.py</code> (given below) code. </p>
<p>For example (request sent to my django):</p>
<pre><code>{
'social':{
'token':'XYZ',
'source':'FB',
},
'user_details':{
'first_name':'sahil',
'last_name':'gandhi',
'username':'sahilgandhi',
'email':'sa***com',
'password':'password',
'date_of_birth':'01/01/2015'
}
}
</code></pre>
<p><strong><em>My approach #2:</em></strong> I stumbled across a <code>post_save()</code> signal in django's framework. this is my code implementing the post_save() method
This doesn't require a combined request like <strong>approach #1</strong> but a simple post request that will be handled by <code>SocialSerializer</code></p>
<pre><code>@receiver(post_save, sender=Social)
def create_user_after_social_signup(sender, instance, created=False, **kwargs):
"""
Automatically create a User instance for every Social signup
:param sender: Social model
:param instance: Social instance that just got created
:param created: is new instance created; boolean
:param kwargs:

"""
if created:
social = Social.objects.get(pk=instance.id)
# get user details from social (ex: facebook)
payload={'access_token':social.token}
url='https://graph.facebook.com/v2.2/me'
r=requests.get(url, params=payload)
# create user from response using:
# User.objects.create_superuser()
</code></pre>
<p>How to do this if facebook's response is this?</p>

jQuery form submission handler - odd behaviour
|
<p>Edit: answered, was a syntax error, see below for fixed code...</p>
<p>Hi all, long time reader, first time asker.</p>
<p>The below code is <em>always</em> allowing form submission, even given that I've overidden the return value at the end of the function, outside of any conditional statements. Form submission is only disallowed if there is NOTHING in the function body except return false. Deeply odd.</p>
<p>I have verified that the function is being called on form submission by entering an alert in the function body and checking that it alerts me. I tried stripping the code out into a discrete function and specifying that as the event handler, no difference.</p>
<p>The workaround is probably to monitor the state of my controls and disable/enable the submit button of the form accordingly, but surely I'm just missing something obvious as this technique works everywhere else.</p>
<p>Does anyone have any ideas? My google-fu has failed me and SO doesn't have anything on this that I could see (yet). I'm at my wit's end. The context for this, btw, is FF3, jQuery 1.4.2, and I'm working on my company's mantisbt installation. The html of the form is completely normal.</p>
<p>Cheers,</p>
<p>G</p>
<pre><code> jQuery(document.forms[2]).submit(function(){
var canSubmit = true;
var msg = '';
// we only do validation if those controls are present and have some options which can be selected
if(jQuery("select[name=priority] option").length() > 0 && jQuery("select[name=severity] option").length() > 0){
//there must be a selection in priority
if(jQuery("select[name=priority]").val() == ''){
canSubmit = false;
msg = msg + 'Please select a priority!\n';
}
//there must be a selection in severity
if(jQuery("select[name=severity]").val() == ''){
canSubmit = false;
msg = msg + 'Please select a severity!\n';
}
//the priority cannot be P1 or P2 and also a feature request
if( jQuery("select[name=priority]").val() > 49
&& jQuery("select[name=severity]").val() == 60){
canSubmit = false;
msg = msg + 'Feature requests cannot be P1 or P2!';
}
//if there is some feedback, alert it to the user
if(msg != ''){
alert(msg);
}
}
//debugging override - always return false!
return false; //instead of canSubmit;
});
</code></pre>
<p>Edit: here's the fixed code. Many thanks Gaby!</p>
<pre><code> var canSubmit = true;
var msg = '';
// validate form submission
jQuery(document.forms[2]).submit(function(e){
msg = '';
canSubmit = true;
// we only do validation if those controls are present and have some
// options
// which can be selected
if(jQuery("select[name=priority] option").length > 0 &&

Fetching different data from the same query in GraphQL
|
<p>For background, we're using HotChocolate in C#, with Apollo Angular and graphql-codegen.</p>
<p>We want to fetch some data from a query, but twice within one named query with different criteria, for instance:</p>
<pre><code>
query getTeamMembers($organisationId: UUID!, $cursor: String) {
teamMembers(organisationId: $organisationId, after: $cursor) {
pageInfo {
hasNextPage
hasPreviousPage
startCursor
endCursor
}
edges {
cursor
node {
...teamMember
}
}
totalCount
}
teamMembersWithSpecificCriteria: teamMembers(organisationId: $organisationId, after: $cursor, where: {...}
] }}) {
totalCount
}
}
</code></pre>
<p>As you can see, this query (<code>getTeamMembers</code>) will fetch data from the same query resolver (<code>teamMembers</code>), but one is the entire dataset, the other is a subset of that data with a where clause.</p>
<p>(I've had to blur/change some names for reasons).</p>
<p>This seemingly <em>works</em> in the network request:</p>
<p><a href="https://i.stack.imgur.com/KzNtr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KzNtr.png" alt="Network request" /></a></p>
<p>but as you can see, both results have the same <code>__typename</code>, causing Apollo Angular to overwrite the data and set <code>23</code> for both:</p>
<p><a href="https://i.stack.imgur.com/o2V80.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/o2V80.png" alt="enter image description here" /></a></p>
<p>The code we have looks like this:</p>
<pre class="lang-js prettyprint-override"><code>
this.teamMembersQuery = this.apollo.watchQuery<GetTeamMembersQuery,
GetTeamMembersQueryVariables>({
query: GetTeamMembersDocument,
fetchPolicy: "cache-and-network",
variables: {
organisationId: currentOrganisation?.id
}
});
this.teamMembers$ = this.teamMembersQuery.valueChanges.pipe(
map((result) => {
this.cursor = result.data.teamMembers?.pageInfo.endCursor;
this.hasNextPage = result.data.teamMembers?.pageInfo.hasNextPage;
this.totalTeamMembersCount = result.data.teamMembers?.totalCount ?? 0;
this.totalSpecificTeamMembersCount = result.data.teamMembersWithSpecificCriteria?.totalCount ?? 0;
return result.data.teamMembers?.edges?.map((e) => e.node) ?? [];
})
);
</code></pre>
<p>Is there a way around this without having to create another query resolver on the server? Isn't this the entire point of GraphQL to be able to query different data like this?</p>
<p>Any tips would be entirely helpful.</p>

Efficient controlled random walks in gremlin
|
<h2>Goal</h2>
<p>The objective is to efficiently generate random walks on a relatively large graph with uneven probabilities of going through edges depending on their type.</p>
<h2>Configuration</h2>
<ul>
<li>Ubuntu VM, 23Go RAM</li>
<li>JanusGraph 0.6.1 full</li>
<li>Local graph (default <code>conf/remote.yaml</code> file used)</li>
<li>~1.8m vertices (~28k will be start nodes for the random walks)</li>
<li>~21m relationships (they can all be used in the random walks)</li>
</ul>
<h2>What I am doing</h2>
<p>I am currently generating random walks with the <code>sample</code> command:</p>
<pre><code>g.V(<startnode_id>).
repeat( local( both().sample(1) ) ).
times(<desired_randomwalk_length>).
path()
</code></pre>
<h2>What I tried</h2>
<p>I tried using a gremlinpython script to create a random walk generator that would first get all edges connected to the current node, then pick randomly an edge to go through and repeat <code><desired_randomwalk_length></code> times.</p>
<pre class="lang-py prettyprint-override"><code>from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection
from gremlin_python.process.anonymous_traversal import traversal
from gremlin_python.structure.graph import Vertex
from typing import List
connection = DriverRemoteConnection(<URL>, "g")
g = traversal().withRemote(connection)
def get_next_node(start:Vertex) -> Vertex:
next_vertices = g.V(start.id).both().fold().next()
return next_vertices[randint(0, len(next_vertices)-1)]
def get_random_walk(start:Vertex, length:int=10) -> List[Vertex]:
current_node = start
random_walk = [current_node]
for _ in range(length):
current_node = get_next_node(current_node)
random_walk.append(current_node)
return random_walk
</code></pre>
<h2>Issues</h2>
<p>While testing on a subset of the total graph (400k vertices, 1.5m rel), I got these results</p>
<ul>
<li>Sample query, <code><desired_randomwalk_length></code> of 10: 100k random walks in 1h10</li>
<li>Gremlinpython function, <code><desired_randomwalk_length></code> of 4: 2k random walks in 1h+</li>
</ul>
<p>The sample command is really fast, but there are a few problems:</p>
<ol>
<li>It doesn't seem to truly be a uniform distribution pick amongst the edges (<a href="https://kelvinlawrence.net/book/Gremlin-Graph-Guide.html#_using_math_random_to_more_randomly_select_a_single_vertex" rel="nofollow noreferrer">it seems to be successive coin tosses</a>) which could lead to certain paths being taken more often, which then diminishes the interest of generating random walks. (I can't directly do what is recommended here as the nodes ids aren't in a sequence, thus I have to acquire them first.)</li>
<li>I haven't found a way to give different probabilities to different types of relationships.</li>
</ol>
<p>Is there a better way to do random walks with Gremlin?<br />
If there is none, is there a way to modify the sample query to rectify the assign probabilities to types of edges? Maybe even a way to have a better distribution of the sampling?<br />
In last recourse, is there a way to improve the queries to make this "by hand" with a gremlinpython script?</p>
<p>Thanks to everyone reading/replying!</p>
<h2>EDIT</h2>
<p>Is there a way to do the following:</p>
<ul>
<li>Given a <code>r_type1</code>, <code>r_type2</code>, <code>r_type3</code>, ... the acceptable relationship type for this random walk</li>
<li>Given a <code>proba1</code>, <code>proba2</code>, <code>proba3</code>, ... the probabilities of going through these relationship types</li>
</ul>
<p>For each step</p>
<ol>
<li>Sample a node for each relationship type <code>r_type1</code>, <code>r_type2</code>, <code>r_type3</code>, ...</li>
<li>Keep only one according to the probabilities <code>proba1</code>, <code>proba2</code>, <code>proba3</code>, ...</li>
</ol>
<p>I think the second step could be done be sampling multiple nodes for each relationships, in accordance with the probas (which could be done by using a <code>gremlinpython</code> script to build the query). This still leaves the question of how to sample on multiple relationships from a single node, and how to randomly pick one in the sampled nodes.</p>
<p>I hope this is clear!</p>

<p>game works as fine,</p>
<pre><code>but have several issues, one issue is this line :
if platform.move_x != 0:
self.rect.x += platform.move_direction
</code></pre>
<p>it colors as yellow color and says :
<a href="https://i.stack.imgur.com/zdrJM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zdrJM.png" alt="enter image description here" /></a></p>
<p>in shortly it says that <code>Unresolved attribute reference 'move_x' for class 'Sprite'</code> , the same is for platform.move_direction, but in Platform class we have both parameters and both are added here :</p>
<pre><code>if tile == 4:
platform = Platform(col_count * tile_size, row_count * tile_size, 1, 0)
platform_group.add(platform)
if tile == 5:
platform = Platform(col_count * tile_size, row_count * tile_size, 0, 1)
platform_group.add(platform)
</code></pre>
<p>also there is second issue :in game player can't stand on moving platform, i mean this picture :
<a href="https://i.stack.imgur.com/Cmqts.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Cmqts.png" alt="enter image description here" /></a></p>
<p>if player is on platform, it falls down, how can i fix this issue? thanks in advance</p>

xdmp:spawn-function() Alternative
|
<p>we have around "20 million" documents in the database and we have created badges of "10000" and use
<strong>xdmp:spawn-function()</strong> to query over these 20 million documents and perform delete operations according to some conditions . But running it through query console, query is getting timeout .. Any alternate option we can look for so that the query doesn't get timed-out</p>
<pre><code>xquery version "1.0-ml";
declare variable $versionToMaintain := 10;
declare variable $batchSize := 10000;
declare function local:delete($values) {
for $value in $values
let $versionToDelete := $value[3] - $versionToMaintain
return
if ($versionToDelete > 0) then
let $query := cts:and-query((
cts:collection-query('collection name 2'),
cts:element-range-query(xs:QName('version'), '<=', xs:int($versionToDelete)),
cts:element-value-query(xs:QName('id'),$value[2]),
cts:element-range-query(xs:QName('c:created-on'), '<=', xs:dateTime(xdmp:parseDateTime('[Y0001]-[M01]-[D01]')
))
return (cts:uris((), (), $query) ! xdmp:document-delete(.))
else ()

Toggling State while using react router
|
<p>By default, I want to show the temperature of the current gps location. But if the user wishes to see the temperature of any other specific country he can do so by providing the country name.</p>
<p>I have used HomeLocation as the toggle, such that whenever '/' is rendered the HomeLocation is set to <code>true</code>, an axios request is made to the api using the Geocoordinates, and if the HomeLocation is set to <code>false</code>, an axios request is made using the country name.</p>
<p>I am not sure if this is the correct way to do it any help would be appreciated.</p>
<pre><code>import React from "react";
import "./App.css";
import Dashboard from "./components/Dashboard/Dashboard";
import { Route, Switch } from "react-router";
import SearchBar from "./components/Dashboard/Searchbar";
import NavBar from "./components/Dashboard/Navlink";
import Weekly from "./components/Weekly/WeeklyDashboard";
function getlocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
} else {
alert("Geolocation not supported");
}
}
function showPosition(position) {
console.log(position.coords.latitude);
}

constructor(props) {
super(props);
this.state = {
Location: "",
HomeLocation: true,

};
}
componentWillMount() {
if (this.state.HomeLocation === true) {
console.log("Make request to open weather api using gps cordinates");
} else {
console.log(
"Make request to open api using the country name provided by the user"
);
}
}
