Calculating Avg, Max, and Min using a .txt input file with both integers and strings mixed
|
<p>Please help. I've looked everywhere and am stumped on how to finish this program. I need to calculate the average, max, and min from a data input file. They need to look like this:</p>
<pre><code>System.out.println("The average total score of the class is: " + total/27);
System.out.println(maxName + "got the maximum score of: " + maxVal);
System.out.println(minName + "got the maximum score of: " + minVal);
</code></pre>
<p>For the average I don't know why the while loop in my main isn't working. It calculates a value of zero. I also don't know how I can make it so the 27 isn't hard coded. For the max and min values, I have no clue about those. i don't even have a guess. A lot of things I've looked at for these use ways we haven't been taught (like a buffered something for instance, or using the Collections class which we haven't learned about that either. I just need a basic way of accomplishing these. I will include everything I have so far. Any help is appreciated. Thank you.</p>

Globalization 1.x with DevExtreme library
|
<p>I have a question with the DevExtreme v.16.1 in combination with Globalize 1.x. They upgraded from 0.x to 1.x and I cannot make it work since the update.</p>
<p>I put the loading of the librries in an external file, and loaded the rest of the application after the promise is resolved.</p>
<p>This is tje importatn part of my localize.js</p>
<pre><code>$(function () {
MK.localisation.init = $.when(
// CLDR libraries for NL-nl
$.getJSON("js/localization/nl/ca-gregorian.json"),
$.getJSON("js/localization/nl/numbers.json"),
$.getJSON("js/localization/nl/currencies.json"),

return [].slice.apply(arguments, [0]).map(function (result) {

$.each(MK.config.navigation, function () {
if (this.title.indexOf('@') === 0) {
this.title = Globalize.formatMessage(this.title.substring(1));
}
});
});
});
</code></pre>
<p>If i put a breakpoint at Globalize.locale("nl"), I see that all messages are loaded inside the Globalize object.</p>
<p>I call this function at the top of my index.js the following way:</p>
<pre><code>$(function () {
//setup localisation
MK.localisation.init.done(function () {
Globalize.locale("de");
//rest of the app decalration follows here
})
</code></pre>
<p>I can also use the translation within JavaScript without problem</p>
<pre><code>Globalize.formatMessage("someString")
</code></pre>
<p>However, the DevExtreme modules are not translated. They remain in english. It is also possible to let strings be translated directly inside the view with the @someString syntax. This does not work with strings i declared either. It does work with the build in strings though, so the parsing does work.</p>
<p>I suspect timing problems, maybe the views are parsed before the strings are loaded? Cannot solve the problem though, followed the manual of devextreme to the point i think...</p>

CarouFredSel sliding issue
|
<p>I have set up a caroufredsel, and have items inside of it. But when I click on my next and previous buttons, the first time it appears to shift 1 item, every click after that it shifts the entire width of the content and back to the beginning.</p>
<p>I have set my scroll items to 3. Does it have something to do with the width of the container?</p>
<pre><code>jQuery('#tab-1').find('#carousel').carouFredSel({
responsive : true,
circular: false,
align: "center",
height : 'auto',
width : 'auto',
auto : false,
prev : {
button : function() {
return jQuery('#tab-1').find('.carousel-pagerLeft');
}
},
next : {
button : function() {
return jQuery('#tab-1').find('.carousel-pagerRight');
}
},
scroll : {
items : 3,
fx : "fade"
},
items : {
height : 'auto',
width: 'auto'
},
swipe: {
onMouse: true,
onTouch: true
}
});
</code></pre>
<p>It also seems that on slide, the height of the carousel changes for some reason. maybe this is related</p>

Trouble printing to a specific Tray (PaperSource) using VB.NET PrinterSettings
|
<p>I've been having trouble automatically selecting a Tray (PaperSource) to print from on a specific printer (HP OfficeJet Pro 9020 series) using VB.NET. I have reduced my code to a bare minimum below to indicate the process I'm following.</p>
<p>After the print dialog has popped up and you select 'Tray 2' from the list. The line of code <code>prn.PrinterSettings = pd.PrinterSettings</code> applies that setting, and it subsequently prints from the correct tray. If, however, you just click ok on the dialog it prints from the wrong tray.</p>
<p>The strange thing is that, as you can see, I set the 'Tray 2' option in code, so, in theory that object should be exactly the same. I used <code>Newtonsoft.JSON</code> to serialise the <code>pd.PrinterSettings</code> object before and after I had selected 'Tray 2' in the dialog so I could compare the differences and they were both identical. The only differences at first were the ones I addressed in the code earlier on. They didn't make any difference though. Those being;</p>
<pre><code>pd.PrinterSettings.PrintFileName = "IP_192.168.1.50"
pd.PrinterSettings.PrinterName = "Dispatch Office"
pd.PrinterSettings.Collate = False
</code></pre>
<p>But for whatever reason, it only works if I explicitly open the dialog and select the desired Tray and click ok. <code>prn.PrinterSettings = pd.PrinterSettings</code> is the only line of code that has any effect on what printer is used, so somewhere in <code>pd.PrinterSettings</code> there must be something missing that I couldn't see in the JSON string. I've had success with this code on other printers, but this specific printer seems to be different, but the problem has to be with VB.NET I would think.</p>
<p>Has anyone come across anything like this before? Here is my full code below.</p>
<pre><code>Private Sub Print()
Dim pd As New PrintDialog
pd.PrinterSettings.PrintFileName = "IP_192.168.1.50"
pd.PrinterSettings.PrinterName = "Dispatch Office"
pd.PrinterSettings.Collate = False
For Each paperSource As Printing.PaperSource In pd.PrinterSettings.PaperSources
If paperSource.SourceName = "Tray 2" Then
pd.PrinterSettings.DefaultPageSettings.PaperSource = paperSource
Exit For
End If
Next
If pd.ShowDialog = DialogResult.OK Then
Dim prn As New Printing.PrintDocument
prn.PrinterSettings = pd.PrinterSettings
AddHandler prn.PrintPage, AddressOf Me.PrintPageHandler
prn.Print()
RemoveHandler prn.PrintPage, AddressOf Me.PrintPageHandler
End If
End Sub
Private Sub PrintPageHandler(ByVal sender As Object, ByVal args As Printing.PrintPageEventArgs)
Dim myFont As New Font("Courier New", 9)
Dim strTextFile = IO.File.ReadAllText("C:\textfile.txt")
args.Graphics.DrawString(strTextFile, New Font(myFont, FontStyle.Regular), Brushes.Black, 50, 50)
End Sub
</code></pre>
<p>Also, just to confirm, this is independent of the print dialog.
The code below which is in the shortest form possible also does not work.</p>
<pre><code>Private Sub PrintAuto()
Dim ps As New Printing.PrinterSettings With {.PrinterName = "Dispatch Office"}
ps.DefaultPageSettings.PaperSource = ps.PaperSources(3) ' Tray 2
Dim prn As New Printing.PrintDocument With {.PrinterSettings = ps}
AddHandler prn.PrintPage, AddressOf PrintPageHandler
prn.Print()
RemoveHandler prn.PrintPage, AddressOf PrintPageHandler
End Sub

Create binary of spaCy with PyInstaller

New pdf for every different customer number

<p>I have tried to cut down the code as much as possible. The most important part of the code is the second block. There are only two scenarios where I need a different bill to address. These are hard coded in shippercarrierdata,shippercarrierdata1.These create pdfs fine. the problem is creating the default addresses for prepaid customers when there is more than one customer I need it to create a new pdf with a list of all the orders for that customer. I am using TCPDF. Any help would be appreciated. </p>

Python: Problem fitting the word2vec embeddings into Keras Sequential Model

<p>I have a very simple Sequential Model:</p>
<pre><code>embedding_size = 100
model = keras.Sequential([
keras.layers.Flatten(input_shape=(embedding_size,)),
keras.layers.Dense(200, activation='relu'),
keras.layers.Dense(50, activation='relu'),
keras.layers.Dense(4, activation='softmax')
])
adam=keras.optimizers.Adam(learning_rate=0.001)
model.compile(optimizer=adam,
loss=["categorical_crossentropy"],
metrics=['accuracy'])
model.summary()
</code></pre>
<p><a href="https://i.stack.imgur.com/dLXTv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dLXTv.png" alt="Model" /></a></p>
<p>For input I have word2vec encoded vectors of size 1x100 for each sentence.</p>
<p>Sample input is like this:</p>
<p><a href="https://i.stack.imgur.com/odXAb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/odXAb.png" alt="Input" /></a></p>
<p>This means, sentence 0 has the above mentioned vector. Corpus length is 9600 hence train_x is a list of size 9600.</p>
<p>train_y is a simple hot_encoded labels class as shown below:</p>

How to access SQLite database in androidRecyclerVIew?
|
<p>I've created a SQLite database which contains two columns: "title" and "content" and don't have any idea how to display it in my android RecyclerView with two textViews "card_title" and "card_content". please kindly help me with this.
Here is my recycler adapter:</p>
<pre><code>public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
private ClipboardManager myClipboard;
private ClipData myClip;
private Context context;
public List<CardItemModel> cardItems;
public RecyclerAdapter(List<CardItemModel> cardItems){
this.cardItems = cardItems;
}
public static class ViewHolder extends RecyclerView.ViewHolder{
ImageView copyButton;
ImageView shareButton;
ToggleButton favButton;
TextView title;
TextView content;
public ViewHolder(View itemView) {
super(itemView);
this.title = (TextView)itemView.findViewById(R.id.card_title);
this.content = (TextView)itemView.findViewById(R.id.card_content);
this.copyButton= (ImageView) itemView.findViewById(R.id.copyButton);
this.shareButton=(ImageView) itemView.findViewById(R.id.shareButton);
this.favButton=(ToggleButton) itemView.findViewById(R.id.favButton);
favButton.setChecked(false);
favButton.setBackgroundDrawable(ContextCompat.getDrawable(favButton.getContext(), R.mipmap.ic_launcher));
}
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item,parent,false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
holder.title.setText(cardItems.get(position).title);
holder.content.setText(cardItems.get(position).content);
holder.copyButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
myClipboard = (ClipboardManager) v.getContext().getSystemService(Context.CLIPBOARD_SERVICE);
myClip = ClipData.newPlainText("label", holder.content.getText().toString());
myClipboard.setPrimaryClip(myClip);
Toast.makeText(v.getContext(), "Copied to clipboard" , Toast.LENGTH_SHORT ).show();
}
});
holder.shareButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, holder.content.getText().toString());
v.getContext().startActivity(Intent.createChooser(share, "Share Text"));
}
});
holder.favButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton favButton, boolean isChecked){
if (isChecked)
favButton.setBackgroundDrawable(ContextCompat.getDrawable(favButton.getContext(),R.mipmap.ic_launcher));
else
favButton.setBackgroundDrawable(ContextCompat.getDrawable(favButton.getContext(), R.mipmap.ic_cart));
}
});
}
@Override
public int getItemCount() {
return cardItems.size();

XSLT element selection based on Choose not working
|
<p>I have the following XML:</p>
<pre><code><Document>
<Row>
<KEY>NIKE|JB|APPAREL|MENS</KEY>
<Period>Nov-21</Period>
</Row>
<Row>
<KEY>FASCINATE|JB|ACCESSORIES|LADIES</KEY>
<Matches>
<Row>
<KEY>FASCINATE|JB|ACCESSORIES|LADIES</KEY>
<Period>Nov-22</Period>
</Row>
</Matches>
</Row>
</Document>
</code></pre>
<p>I want to use XSLT to return the nested <code>/Matches/Row/Period</code> when the <code>Document/Row/Period</code> is undefined (as it is in the second <code>Row</code> of the XML)</p>
<p>So I have the following XSLT:</p>
<pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns="http://exampleincludednamespace.com/"
exclude-result-prefixes="ns">
<xsl:output method="xml" omit-xml-declaration="yes" />
<xsl:template match="/">
<Document>
<xsl:for-each select="/Document/Row">
<xsl:variable name="period" select="/Period" />
<xsl:choose>
<xsl:when test="$period = null">
<xsl:copy>
<xsl:copy-of select="KEY | /Matches/Row/Period" />
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:copy-of select="KEY | Period" />
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</Document>
</xsl:template>
</code></pre>
<p></xsl:stylesheet></p>
<p>But it returns the following output:</p>
<pre><code><Document>
<Row>
<KEY>NIKE|JB|APPAREL|MENS</KEY>
<Period>Nov-21</Period>
</Row>
<Row>
<KEY>FASCINATE|JB|ACCESSORIES|LADIES</KEY>
</Row>
</Document>
</code></pre>
<p>(Note how it is not returning the nested <code>/Matches/Row/Period</code> in the second <code>/Row</code>.</p>
<p>I expect to get the following output:</p>
<pre><code><Document>
<Row>
<KEY>NIKE|JB|APPAREL|MENS</KEY>
<Period>Nov-21</Period>
</Row>
<Row>
<KEY>FASCINATE|JB|ACCESSORIES|LADIES</KEY>
<Period>Nov-22</Period>
</Row>
</Document>
</code></pre>
<p>What am I doing wrong?</p>

Optimize Excel VBA Macro for Copy-PasteValues
|
<p>I'm new in Excel-VBA and I need to improve my macro performance. I have a macro that searches an excel, opens it, then goes through every sheet and copy-pastevalues for all cell with a specific color (yellow). Finally saves and closes the excel. In addition, excels sheets are locked and only those yellow cells are editable. This should be done for a list of excel that I indicate in a main template from where I call the macro. The problem is that it takes a lot of time and even gets blocked when the number of excels is more than 3.</p>
<p>I paste my code below and hope anyone can help. Thanks!</p>

Need help getting OneToMany association from ManyToOne
|
<p>Let me start off by saying I asked a similar question before and got it answered. I tried using those principles here but I'm stuck again am am not sure where to go from here. </p>
<p>I have a page where I list out all the 'products' along with their respected id's, price, and name. On this same page I want to get a description I created for each of them. Description is its own entity and has it's own controller. </p>
<p>In my <code>ProductController</code>, within my <code>indexAction</code>, I'm trying to get the description to appear here. </p>
<p>The problem is, I don't reference an id within <code>indexAction</code> (I use findAll). I have tried to loop through all products and reference using <code>$key</code> but I either get the most recent description entered in description or currently:</p>
<p><em>Error: Call to a member function getDescriptions() on a non-object.</em></p>

How to draw Color Bands in Flex Chart?
|
<p>I want to draw a custom background in my flex chart with vertical axis is linear and horizontal axis is category. In background i want to shade the regions according to data given by user.
I tried CartesianDataCanvas and gridlines in chart backgroundelements but not getting a good solution. Anyone have an idea? i prefer using script without mxml.
Thanks in advance..</p>
<p>I am adding my code to show the issue i faced while using CartesianDataCanvas. It is working perfectly in Area chart, but i want to draw in Bubble chart. As bubble series is not starting from the begining of horizontal category axis, CartesianDataCanvas start drawing from the mid point of the first bubble. But i am trying to draw the rectangle in the whole width of chart.</p>

Remove duplicate rows where col1 and col2 are equal but reversed
|
<p>I have a query that has the following results. How can I modify this query to remove duplicate rows. In this case, the duplicates would be "row1.antecedent = row2.consequent and row2.antecedent= row1.consequent". I only need one such row, not both in my results. Also, this logic has to be directly added in the query, not the encompassing programming language.</p>
<p><a href="https://i.stack.imgur.com/CAU5m.png" rel="nofollow noreferrer">Query Results</a></p>
<p>So let's assume this my table with the data as shown. I would like to select rows from this table such that only rows with rule_id = 943,945 and 979 are selected. That's because 944 gives me same results as 943; 946 is same as 945 and 980 is same as 979, except with the antecedent and consequent reversed. Please ignore the value CONF. That would be different.</p>

Slow camera and app close within less than minute
|
<p>I'm developing an android application which detect text using OpenCV's MSER algorithm. The application is working just fine and doing what it should do, but it closes after less than 1 minute! note that there is no errors or something. I think the problem is with the memory, I monitored the memory of my device while the application was running and there was memory left in my device still it stop working and return me to my phone's home page and close the music if I'm listening to something. I think that the application is very heavy and doing so much work that why the camera became slow and it close suddenly. </p>
<p>I don't know how to solve this problem.. can someone tell me how to solve this?</p>

C macro's argument limiting by argument prefix
|
<p>I have a set of defined macros as follows.</p>
<pre><code> #define ARM_FRONT_REG 1
..............
#define ARM_REAR_REG 10
#define MOTOR_MAIN_REG 1
..............
#define MOTOR_AUX_REG 3
#define MOTOR_REGISTER_ADDRESS(register_offset) \
( \
addr = MOTOR_BASE_ADDR * (1 << BITS_PER_MODULE) + register_offset) \
) \
#define ARM_REGISTER_ADDRESS(register_offset) \
( \
addr = ARM_BASE_ADDR * (1 << BITS_PER_MODULE) + register_offset) \
) \
</code></pre>
<p>I am using macros like</p>
<pre><code>ui_address = ARM_BASE_ADDR (ARM_REAR_REG)
ui_address = MOTOR_REGISTER_ADDRESS (MOTOR_MAIN_REG)
</code></pre>
<p>I want to restrict macro usage which is mixed with each other. Is there a way of aborting compiling if macros used as following?</p>
<pre><code>ui_address = ARM_BASE_ADDR (MOTOR_MAIN_REG)
ui_address = MOTOR_REGISTER_ADDRESS (ARM_REAR_REG)
</code></pre>
<p>PS :
I have mentioned macros in brief, But actual macros are as below, which used to perform register reads write to Linux driver from user application.</p>
<p>actual struct :</p>
<pre><code>struct hw_register_struct
{
int log_level;
unsigned int reg_addr;
unsigned int reg_value;
char reg_name [MAX_REG_NAME_LENGTH];
char application_info [APP_INFO_LENGTH];
};
</code></pre>
<p>This macro validates the address is correct per module.</p>
<pre><code> #define CHECK_ADDR_SUB_MODULE(module_index, sub_module, sub_module_bits, offset, max_reg_count)
({
unsigned int check_ret = 0;
if(offset >= max_reg_count){
hw_register.reg_addr = 0;
check_ret = 1;
} else {
hw_register.reg_addr = (module_index * (1 << BITS_PER_MODULE) + (1 << sub_module_bits) * (sub_module) + offset);
}
check_ret;
})
</code></pre>
<p>This macro assigns the address to the variable in the struct.</p>
<pre><code> #define SEQUENCER_REGISTER_ADDRESS(register_offset)
({
memset((void *)&hw_register, 0, sizeof(struct hw_register_struct));
if(CHECK_ADDR_SUB_MODULE(MODULE_SEQUENCER, 0, register_offset, SEQ_REG_COUNT)){
Logger::Print(ERROR_LEVEL, "Invalid Address | Module : %s | Address : %s", STR(MODULE_SEQUENCER), #register_offset);
}
memcpy(hw_register.reg_name, #register_offset, sizeof(#register_offset));
hw_register.reg_addr;
})
</code></pre>
<p>Perform calling the ioctl to Linux driver</p>
<pre><code> #define WRITE_REGISTER_(register_addr, register_value, func, line, log_level_)
{
register_addr;
hw_register.reg_value = register_value;
hw_register.log_level = log_level_;
snprintf(hw_register.application_info, APP_INFO_LENGTH - 1,"%s:%d", func, line);
long ret_ioctl = p_IOCTL->IOCTL<struct hw_register_struct>(IOCTL_WRITE, hw_register);
if(unlikely(ret_ioctl != 0))
{
Logger::Print(ERROR_LEVEL, "IOCTL WRITE_REGISTER Failed | Reg: %u, Reg Name [ %s ]", hw_register.reg_addr, hw_register.reg_name);

Inconsistency in UI display between computers
|
<p>So me and a couple of friends are working on a project using flutter and firebase and all that and this is all of our first time working with flutter. One friend has been working on most of the UI elements and it looks perfectly fine on his end, but when we run it it looks completely different and squashed. We all have flutter up to date, we all have the same code from the same github repo, and we all have the same resolution screens if any of that would matter.</p>
<p><a href="https://imgur.com/a/9sMOhON" rel="nofollow noreferrer">https://imgur.com/a/9sMOhON</a></p>
<p>The first image is what the person who made the UI sees and the second is what the rest of us see when running it (besides the new graph as that was just added recently)</p>
<p><strong>Edit</strong>
Here is some of the offending code:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

Can't restore OrientDB Backup
|
<p>I'm having trouble restoring an OrientDB database from a backup. I'm using OrientDB version 1.2.0 (this backup is from November 2012) and the backup was produced by OrientDB (same version) using the built-in backup utility. I'm trying to restore the backup to a new database using the OrientDB console:</p>
<pre><code>create database remote:localhost/dbname root password local graph
import database backup.json
</code></pre>
<p>But when I run those commands, I get the following error in the console:</p>

<p>All of the records import correctly, but it fails on the indexes. I have 15+ backups of the same database and they all have this issue, so it seems unlikely that they're all corrupted. How can I restore my database? (I'm OK with having to modify the JSON if needbe.)</p>

<p>It seems like the issue is that my old cluster IDs don't match the ones in the new database. Perhaps there are creation options that affect which clusters are created by default?</p>

<p>I am getting the position as 1,2,3,4 using the position(). What I want is output for the position() should be 1,2,1,2 based on "QualifyingCode" attribute.</p>

Title Artist ID
title1 artist1 1
title2 artist2 2
title3 artist3 3
title4 artist4 4

Title Artist ID
title1 artist1 1
title2 artist2 2
title3 artist3 1
title4 artist4 2

Can't get WordPress hook to fire inside embedded class
|
<p>I am trying to build some nice metabox functionality with some oop.</p>
<p>I have my main DazSEO class, which inside contains a Metabox Class.</p>
<p>When I set WordPress save data hooks up inside the metabox class, they won't fire, but when I set them up from the root class, they will.</p>
<p>Is using hooks inside embedded classes incompatible with the WordPress hook system?</p>
<p>Any help would be appreciated here as I have spent a lot of time trying to figure out what is the issue here, I guess it is some object scope issue for the wp engine, but I am not convinced.
class DazSEO {
public static $plugins = array();</p>
<pre><code>public $metaBox;
public function __construct() {
add_action('admin_init', array($this, 'adminInit') );
add_action('init', array($this, 'init'));
}
public function adminInit() {
$this->setupMetaBox();
}
public function setupMetaBox() {
if( $pagenow === 'term.php' ) { // returns true
if( isset($_GET['taxonomy']) ) {
$term = get_term( $_GET['tag_ID'], $_GET['taxonomy'], OBJECT );
require_once('admin\metabox\TermMetaBox.php');
$this->metaBox = new TermMetabox( $_GET['taxonomy'] ); // confirmed this does fire
DazSEO::$mode = 'term';
DazSEO::$wpID = $_GET['tag_ID'];
DazSEO::$typeName = $_GET['taxonomy'];
}
}
}
}
class TermMetabox extends MetaBoxBase {
private $_taxonomy;
public function __construct(string $taxonomy) {
if( strlen($taxonomy) === 0 ) { echo 'no taxonomy passed'; exit(); }
$this->_taxonomy = $taxonomy;
add_action( $this->_taxonomy . '_edit_form', array($this, 'buildMetaBox') );
add_action('edit_terms', array($this, 'onTermSave')); // SETUP TERM SAVE
}
public function loadHooks() {
}
// NOT BEING CALLED
public function onTermSave(int $term_id) {
echo '<pre>' . print_r($_REQUEST, 1) . '</pre>'; exit();
if( $this->onSaveChecks($term_id) ) {
return;
}
foreach(DazSEO::$plugins as $plugin) {
$plugin->onTermSave($term_id, $_REQUEST);
}
}
}
</code></pre>
<p>The TermMetabox:: onTermSave never gets called</p>
<p>If this is called from the root class (DazSEO), and I move the save method in there too it works...</p>
<pre><code>add_action('edit_terms', array($this, 'onTermSave'));
</code></pre>
<p>But it's messy design like that.</p>
<p>This plugin is initialized like this...</p>
<pre><code>$dazSEO = new DazSEO();
$wpCleanHeader = new RemoveWPHeaderJunk();
$dazSEO->loadPlugin($wpCleanHeader);

define an explicit mapping for it.

How to populate treeview in backgroundworker C#

<p>I have those below code that populate a treeview named treeView1 with data from JSON file using JSONnet. If I open a large json file, the UI hang during the populating progress, so how can I make everything happen in a backgroundworker and show a progressbar for populating progress? thanks</p>

How to apply custom font to multiple TextViews within a fragment?
|
<p>I am trying to change the default font for multiple TextViews in android fragment by a custom font. The code to accomplish this is in onCreateView of thefragment as shown below:</p>
<pre><code>@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_interest, container, false);
TextView txt1 = (TextView)v.findViewById(R.id.textView1);
TextView txt2 = (TextView)v.findViewById(R.id.textView2);
Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/HoneyScript-SemiBold.ttf");
txt1.setTypeface(font);
txt2.setTypeface(font);
return v;
</code></pre>
<p>}</p>
<p>The code works if I change the font for only a single TextView but attempting to change font for multiple TextViews as in the code above, I am getting NullPointerException error:</p>

One session design pattern for EJB JPA and GWT RequestFactory aka keeping JPA session between multiple method calls
|
<p>The setup is like this:</p>
<p><strong>Front-end:</strong> <code>GWT</code> using <code>RequestFactory</code> for sending data objects<br>
<strong>Back-end:</strong><br>
<em>Web-layer:</em><br>
<code>GWT</code> server side code which has injected EJB<br>
<em>EJB-layer:</em><br>
Stateless sesion beans: </p>
<p><strong>Data access bean</strong> (<code>DAB</code>)=> has injected <code>EntityManager</code> for <code>JPA</code> operations and provides methods for merging and retrieving of entities<br>
<strong>Facade bean</strong> (<code>FB</code>) => calls methods of DAB and is interface between EJB and web layer</p>
<p>When an entity object (lets say <code>MyEntity</code>) is to be saved after it has been modified at the client side, the flow is like this:<br>
1. Initiated by the client<br>
2. Server side <code>GWT</code> code is run and invokes the following methods:<br>
3. The <code>find()</code> method looks up the instance of <code>MyEntity</code> using <code>FB.findMyEntity()</code> which calls <code>DAB.findMyEntity()</code> which in turn uses <code>EntityManager</code> to do the look-up. The <code>find()</code> method must be invoked as its part of <code>RequestFactory</code> flow in <code>GWT</code>.<br>
4. The <code>save()</code> leads to <code>FB.saveMyEntity()</code> --> <code>DAB.saveMyEntity()</code> --> <code>EntityManager.merge()</code> and the changed entity object is persisted.</p>
<p>It is obvious that each of <code>find()</code> and <code>save()</code> methods run in different <code>JPA</code> transaction which is ineffective and bad design. </p>
<p>With regards to keeping the facade bean interface with simple look-up and saving methods:</p>
<ol>
<li>What is the best design to handle this situation? - preferably with having both method calls in one <code>JPA</code> transaction.</li>
<li>What are alternatives? With pros and cons.</li>
</ol>
<p>EDIT: Including simplified examples of the code for <code>FB</code> and <code>DAB</code>. </p>
<p>Facade bean (<code>FB</code>):</p>
<pre><code> @Stateless
public class MyFacadeBean implements MyFacade{
@EJB
private DataAccessBean dab;
@Override
public void saveMyEntity(MyEntity entity) {
dab.saveMyEntity(entity);
}
@Override
public void findMyEntity(int id) {
dab.saveMyEntity(id);
}
}
</code></pre>
<p>Data access bean (<code>DAB</code>):</p>
<pre><code> @Stateless
public class DataAccesseBean implements DataAccessBeanInterface{
@PersistenceContext
private EntityManager entityManager;
@Override
public void saveMyEntity(MyEntity entity) {
entityManager.merge(entity);
}
@Override
public void findMyEntity(int id) {
entityManager.find(MyEntity.class,id);
}
}

ajax load posts as full page slides
|
<p>I've been scratching my head over this and wondering if anyone has a solution. Effectively I'm creating a full viewport slider that dynamically loads the posts into a hidden div that is then animated into the page based on the direction the arrow is clicked. I can get the hidden div to animate in, however the script stops running after the first click so all other posts are not getting pulled in.</p>
<p>HTML/PHP:</p>
<pre><code>// First Div that hold all loaded data
<div id="Default" class="main">
<div id="fullContent">
<?php while ( have_posts() ) : the_post(); ?>
<?php the_title(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
<div class="leftArrow">
<?php previous_post_link_plus( array('format' => '%link', 'order_by' => 'menu_order', 'loop' => true) ); ?>
</div>
<div class="rightArrow">
<?php next_post_link_plus( array('format' => '%link', 'order_by' => 'menu_order', 'loop' => true) ); ?>
</div>
</div>
</div>
// Second div where new content will be loaded
<div id="LoadAjax" class="direction"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
</code></pre>
<p>JQUERY</p>
<pre><code>$.ajaxSetup({cache:false});
$('body').on('click', '.rightArrow a', function(e){
e.preventDefault();
history.pushState({ path: this.path }, '', this.href);
$('.direction').hide();
RightSlide(this);
return false;
});
$('body').on('click', '.leftArrow a', function(e){
e.preventDefault();
$('.direction').hide();
history.pushState({ path: this.path }, '', this.href);

function RightSlide(that) {
var post_id = $(that).attr('href');
$('.direction').load(post_id + ' #fullContent', function(){
// Animate Slides In & Out
setTimeout(function(){

</code></pre>
<p>As you can see on initial load it all works as expected, however if I then go to click right again nothing executes.</p>
<p>My question, is there a way to reset the function on the second click? And what is the reason that it doesn't run on the second click through?</p>
<p>Thanks for your help in advanced. Absolute amateur in this subject so any feedback will be appreciated to help me learn.</p>
<p>Cheers,</p>
<p>A</p>
<p>Edit: Added addition scripts</p>
<p>Solution:</p>
<pre><code>$.ajaxSetup({cache:false});
$('body').on('click', '.rightArrow a', function(e){
e.preventDefault();
history.pushState({ path: this.path }, '', this.href);
$('.disableClicks').show();

How to make my code with ellipsoidhull and for/if loop more efficient
|
<p>My code is structured so that I create an ellipse through my first three points of data. Then I go through each next row, and if the point falls outside the ellipse, I record the minimum distance between the point and ellipse. These points have datetime associated with it so I can only keep points 10 minutes old in my ellipse (so it doesn't get too big). The code works great until I have to process 100K+ of observations. Then the process time goes from minutes to hours. My question is, is there any part of my for loop portion of code that I can restructure to cut process time? Code below for reference. Any help is greatly appreciated.</p>

crash when i try to create a path between two points in osmdroid

<p>I have recently started studying android and kotlin programming, I'm trying to create an application that allows you to create one or more routes on a map, save it and then retrieve it when necessary. I chose to use osmDroid and osmBonusPack because open source but I don't find much documentation online, I'm trying to visualize a path between two Markers, I was able to visualize two markers and draw a straight line between two other points, now I'm trying to make the path but I don't understand how to proceed. Following the tutorial:</p>

The dropdown menu button stays open and won't close
|
<p>I have got a dropdown menu button and when clicked on the icon it should open and when clicking off the icon or on the icon then it should close again, but instead it stays open.</p>
<p>Here is a screenshot, to what i am referring too.</p>
<p><a href="https://imgur.com/VbU5nit" rel="nofollow noreferrer">https://imgur.com/VbU5nit</a></p>
<p>I have researched regarding this issue, but i am unable to find a solution.</p>
<p>My CSS is on paste bin at <a href="https://pastebin.com/BHXNjtWJ" rel="nofollow noreferrer">https://pastebin.com/BHXNjtWJ</a></p>
<p>This is because the CSS is to long to fit on here.</p>
<p>My HTML is:</p>

<p>but the problem is header in the grid is not fixed and
the one am printing is showing the grid with header not fixed.</p>
<p>Header in the grid being not fixed is fine but when am trying to print that grid and scroll down, the header position is misplaced.</p>
<p>can anyone suggest how to apply stylesheet for the grid that am printing, so that header will be fixed </p>
<p>Thanks in advance,</p>

How to speed up document append to existing array in elasticsearch?
|
<p>I am using elasticsearch version 6.3.1.
And I am creating a nested type field,I have created this field to append all the documents of same ID.</p>
<p>Here is my schema for index:-</p>
<pre><code>curl -XPUT 'localhost:9200/axes_index_test12?pretty' -H 'Content-Type: application/json' -d'
{
"mappings": {
"axes_type_test12": {
"properties": {
"totalData": {
"type": "nested",
"properties": {
"gpsdt": {
"type": "date",
"format":"dateOptionalTime"
},
"extbatlevel": {
"type": "integer"
},
"intbatlevel" : {
"type" : "integer"
},
"lastgpsdt": {
"type": "date",
"format":"dateOptionalTime"
},
"satno" : {
"type" : "integer"
},
"srtangle" : {
"type" : "integer"
}
}
},
"imei": {
"type": "long"
},
"date": {
"type": "date", "format":"dateOptionalTime"
},
"id" : {
"type" : "long"
}
}
}
}
}'
</code></pre>
<p>And to append into existing array I call following API : -</p>
<p>Here is the documents which I have to append:-</p>
<pre><code>data={
"script" : {"source": "ctx._source.totalData.add(params.count)",
"lang": "painless",
"params" : {"count" : { "gpsdt" : gpsdt,
"analog1" : analog1,
"analog2" : analog2,
"analog3" : analog3,
"analog4" : analog4,
"digital1" : digital1,
"digital2" : digital2,
"digital3" : digital3,
"digital4" : digital4,
"extbatlevel" : extbatlevel,
"intbatlevel" : intbatlevel,
"lastgpsdt" : lastgpsdt,
"latitude" : latitude,
"longitude" : longitude,
"odo" : odo,
"odometer" : odometer,
"satno" : satno,
"srtangle" : srtangle,
"speed" : speed
}
}
}
}
</code></pre>
<p>Document Parsing:-</p>
<pre><code>json_data = json.dumps(data)
</code></pre>
<p>And API url is: -</p>
<pre><code>API_ENDPOINT = "http://localhost:9200/axes_index_test12/axes_type_test12/"+str(documentId)+"/_update"
</code></pre>
<p>And Finnaly I call this API:-</p>
<pre><code>headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
r = requests.post(url = API_ENDPOINT, data = json_data,headers=headers
</code></pre>
<p>Everything is fine with this but I am not getting good performance when I append new documents in existing array.</p>
<p>So please suggest me what changes I should make?
And I have 4 node cluster, 1 master, 2 data nodes and one cordinator node.</p>

Generate new matrix from old matrix with specific conditions
|
<p>I have matrix <code>R(100*100)</code> and I want to generate new matrix <code>A(100*100)</code> as below conditions</p>
<p>If I have a frequency to add a new condition<code>(let us say frequency = 20)</code>. This mean I will have five conditions inside my domain `(100/20)=5</p>
<pre><code>From 1 to 20, from 21 to 40, from 41 to 60, from 61 to 80, and from 81 to 100.
</code></pre>
<p>Let us assume my original matrix is</p>
<pre><code> [1 1 1……..1]
[2 2 2 …….2]
[3 3 3 ………3]
And so on
[100 100 100 …..100]
</code></pre>
<p>The new matrix must be</p>
<pre><code>From 1 to 20 same as old matrix
[1 1 1……..1]
[2 2 2 …….2]
[3 3 3………3]
From 21 to 40
A(21,j)=R(21,j)+R(1,j) (row 21 + row 1)
A(22,j)=R(22,j)+R(2,j) (row 22 + row 2)
A(23,j)=R(23,j)+R(3,j) (row 23 + row 3)
And so on
From 41 to 60
A(41,j)=R(41,j)+R(21,j) +R(1,j) (row 41+row 21 + row 1)
A(42,j)=R(42,j)+R(22,j) +R(2,j) (row 42+row 22 + row 2)
And so on
A(81,j)=R(81,j)+R(61,j)+R(41,j)+R(21,j)+R(1,j) (row 81+row 61 + row 41 + row 21+ row 1)
</code></pre>
<p>At each time that I reach to the frequency, I will have a new condition.
My question is there any sufficient way to do that? I wrote my code and its work fine but each time I change frequency I will have a new condition. For the case above I have <code>5 conditions</code> but if I use <code>frequency 5</code> I will have <code>20 conditions</code> and I need to change all equations. I mean I need code to be able to handle any frequency</p>
<p>I wrote below code</p>
<pre><code>clc;
clear;
prompt = 'Enter Frequency='; %Frequency=20
N= input(prompt);
Frequency=N;
one_step=1/Frequency; %Frequency
time=Frequency*one_step;
number_of_steps=time/one_step; %Number of steps until next condition
total_steps=100;
R1 = rand(100,100);
Number_of_Lines=(total_steps/number_of_steps)+1; %100/20
A(100,100)=0;
for i=1:100
for j=1:100
if i>=1 && i<=number_of_steps
A(i,j)=R1(i,j);
elseif i>number_of_steps && i<= 2*number_of_steps
A(i,j)=R1(i,j)+R1(i-number_of_steps,j);
elseif i>2*number_of_steps && i<= 3*number_of_steps
A(i,j)=R1(i,j)+R1(i-number_of_steps,j)+R1(i-2*number_of_steps,j);
elseif i>3*number_of_steps && i<= 4*number_of_steps
A(i,j)=R1(i,j)+R1(i-number_of_steps,j)+R1(i-2*number_of_steps,j)...
+R1(i-3*number_of_steps,j);
elseif i>4*number_of_steps && i< 5*number_of_steps
A(i,j)=R1(i,j)+R1(i-number_of_steps,j)+R1(i-2*number_of_steps,j)...
+R1(i-3*number_of_steps,j)+R1(i-4*number_of_steps,j);
end
end

Too many redirect
|
<p>I have this php script ( phpfanlist ) with an admin section that refused to work one day. I guess it came with a php update or something. I didn't mind at the time but now it's bugging me big time.</p>
<p>I made research, I checked the log and all ( there was a depreciate <strong>=& new</strong> in front.inc.php but I corrected it, so that's fine ) but the login page still redirect to a blank page after successful login. If the login is not successful, it throws back an error message.
If I manually try to enter the admin section ( admin.php ) <strong>after</strong> successfully login-in, I get into the admin without problem.</p>
<p>I checked the log and I don't get any message, at all.
How can I make that login page work ? I just want to enter the admin without typing it manually ...
Is the code too old ?</p>
<p>So, <code>login.php</code> gives a form to enter login/pass</p>
<ul>
<li>Successful login : reload <code>login.php</code> to blank page of <code>login.php</code></li>
<li>Unsuccessful login : reload <code>login.php</code> with unsuccessful message</li>
<li>What it's suppose to do on successful login : open <code>admin.php</code></li>
</ul>
<p>This is login.php : </p>
<pre><code>require_once('includes/front.inc.php');
$passok = true;
if (isset($_POST['user']) && isset($_POST['pass']) && (strcasecmp($_POST['user'], $fanlisting->settings['admin_name']) == 0) && (strcmp($_POST['pass'], $fanlisting->settings['admin_pass']) == 0)) {
session_start();
header("Cache-control: private"); // IE fix!!!
$_SESSION['loggedin'] = 1;
if (!isset($fanlisting->settings['cookie_lifetime'])) {
$fanlisting->settings['cookie_lifetime'] = 60;
}
if (isset($_POST['rememberme']) && ($_POST['rememberme'] == 'yes')) {
setcookie('phpfanlist_rememberme', 'yesplease', time()+60*60*24*$fanlisting->settings['cookie_lifetime'], '/');
setcookie('phpfanlist_username', $_POST['user'], time()+60*60*24*$fanlisting->settings['cookie_lifetime'], '/');
} else {
setcookie('phpfanlist_rememberme', FALSE, time()+60*60*24*$fanlisting->settings['cookie_lifetime'], '/');
setcookie('phpfanlist_username', FALSE, time()+60*60*24*$fanlisting->settings['cookie_lifetime'], '/');
}
if (isset($_SESSION['previous_url'])) {
$url = $_SESSION['previous_url'];
unset($_SESSION['previous_url']);
} else {
$url = 'admin.php';
}
header('Location: ' . $url);
exit;
} else { (isset($_POST['pass'])) ? $passok = false : $passok = true; }
</code></pre>
<p>EDIT : so, it looks like there's too many redirect from admin.php
Looking at admin.php doesn't seem to give much info</p>
<pre><code>// Password protect it \\
session_start();
header("Cache-control: private"); // IE fix!!!
if (isset($_GET['action']) && ($_GET['action'] == 'logout')) {
$_SESSION = array();
}
if ((!isset($_SESSION['loggedin'])) || ($_SESSION['loggedin'] != 1)) {
header('Location:admin.php');
exit;
}
/***********************/
require_once('includes/inc.php');
require_once(realpath(PHPFANLIST_INCLUDES . 'admin.inc.php'));
</code></pre>
<p>Header of admin.inc.php is just asking for </p>
<pre><code>require_once('./includes/inc.php');
// Get the actions
require_once('admin.scripts.inc.php');
$fanlisting->LastChecked();
</code></pre>

Trying to understand lists of dictionaries
|
<p>This is my looping code</p>
<pre><code>for netid,email,first,last in notification_list: # put list data in usable format
suspend_stat_dict['netid'] = netid # fill dictionary
suspend_stat_dict['email'] = email # fill dictionary
suspend_stat_dict['added_day'] = added_day # fill dictionary
suspend_stat_dict['deletion_date'] = suspend_day # fill dictionary
pername_addy = convert_address(email) # make sure email in @uconn.edu form
for google_data in user_emails:

angularjs multiple countdown
|
<p>Im in need to make a countdown like this:</p>
<pre><code><div class="countdown" countdown="1482400417">00:10:02</div>
</code></pre>
<p>where the countdown attribute is the time when its finished. the difference is showed in hours:minutes:secs , and it updates each second.</p>
<p>How would i do this in angularjs, when i have multiple countdowns like that?</p>
<p>I did a little digging, and i found something that did something simular, but i couldnt understand the code. So ill post the code i found:</p>
<pre><code>Travian.Directive.countdown = function(a) {
return function(c, b, l) {
function g() {
if ("undefined" != typeof a.K()) {
h = b.attr("countdown");
var c = h - a.K();
if (0 > c || isNaN(c)) {
return Travian.tick.unbind(e), e = null, b.text(
la(0)), !1
}
var g = "";
l.showDaysLimit && c >= l.showDaysLimit ? (c = Math
.round(c / 86400), c == f ? g = m : (g =
Travian.translate("ForDays", {
x: c
}), f = c)) : g = la(c, l.countdownShort &&
c < l.countdownShort);
m != g && (m = g, b.text(g))
}
}
var h, e = null,
m = "",
f = 0;
l.showDaysLimit && c.$on("newTranslation", function() {
f = 0
});
l.$observe("countdown", function(a) {
"undefined" != typeof a && null == e && (e =
Travian.tick.bind(g))
});
b.bind("$destroy", function() {
Travian.tick.unbind(e)
})
}
};
Travian.tick = new function() {
var a = {};
(function B() {
window.setTimeout(B, 100);
var b = {}, c;
for(c in a) {
a.hasOwnProperty(c) && "function" === typeof a[c] && (a[c](), b[c] = a[c])
}
a = b
})();
return{bind:function(b, c) {
"function" === typeof b && (c = b, b = na("tick"));
c();
a[b] = c;
return b
}, unbind:function(b) {
a[b] = null

jQuery datatables loaded from JSON, row click event only firing on sort
|
<p>In part of my Rails 3.2 app I am loading a datatable from server side JSON similar to <a href="http://railscasts.com/episodes/340-datatables?view=asciicast" rel="nofollow">Railscast #340</a>. </p>
<p>I'm trying to call a row click event on the row to load a separate detailed view next to the table and the jQuery click event doesn't fire on tr click, but does fire when a column is sorted. I use similar code elsewhere on the app, but those tables are from smaller datasets and don't use a JSON API. </p>
<p>My code is pretty simple.</p>
<h2>the view</h2>
<pre><code><div id="leads-wrapper">
<h1>Listing all leads</h1>
<table id="leads_table" class="table" data-source="<%= leads_url(format: "json") %>">
<thead>
<tr>
<th>Lead ID</th>
<th>First name</th>
<th>Last name</th>
<th>Company</th>
<th>Rating</th>
<th>Email</th>
<th>Phone</th>
<th>Job Title</th>
<th>Date Added</th>
</tr>
</thead>
</table>
</div>
</code></pre>
<h2>jQuery</h2>
<pre><code>$(document).ready(function () {
$('#leads_table').find("tr").on("click", function (e) {
console.log('clicked');
var link;
link = $(this).children('.id').first();
e.preventDefault();
var url = '/lead_detail/' + $(link).data("id");
$.ajax(url, {
beforeSend: function () {
$('#wait').show();
$("#lead-information").hide();
},
dataType: 'script',
type: 'GET',
complete: function (response) {
$('#lead-information').empty().append(response["responseText"]);
$("#lead-information").show();
//other stuff...
}
});
});
</code></pre>
<p>Everything loads correctly and this code has been working in production for over a year, but adding the new detail view to it is the change. I know I can exclude the sort event from my click jQuery above, but I'm more worried about why the click event doesn't fire for tbody rows right now. </p>
<p>In case anyone is interested, the generated code is what you'd expect: </p>
<pre><code><table id="leads_table" class="table dataTable" data-source="http://localhost:3000/leads.json" aria-describedby="leads_table_info">
<thead>
<tr role="row"><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 96px;" aria-label="Lead ID: activate to sort column ascending">Lead ID</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 130px;" aria-label="First name: activate to sort column ascending">First name</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 128px;" aria-label="Last name: activate to sort column ascending">Last name</th><th class="sorting_asc" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 118px;" aria-label="Company: activate to sort column ascending">Company</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 85px;" aria-label="Rating: activate to sort column ascending">Rating</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 75px;" aria-label="Email: activate to sort column ascending">Email</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 81px;" aria-label="Phone: activate to sort column ascending">Phone</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 112px;" aria-label="Job Title: activate to sort column ascending">Job Title</th><th class="sorting" role="columnheader" tabindex="0" aria-controls="leads_table" rowspan="1" colspan="1" style="width: 147px;" aria-label="Date Added: activate to sort column ascending">Date Added</th></tr>

If cell value the same as above, then
|
<p>I am trying to check if the value in a cell in Column B is the same as a cell in Column B in another row, Y places lower/higher. Y being a value in cell "A8".</p>
<p>IF the values are the same then the value in Column P of the same row has to get the same value as in Column R of the same row.<br />
ELSE Column Q of that row has to get the same value as in Colom R of the same row.</p>
<p>In the schematic below, Y=2, so column B1 check 2 places lower B3 is the same so data in R1 should also be in P1.<br />
Continuing the same idea B4 compared with B6 does not have the same value so the Q4 should have the same value as R4.</p>

How to properly detach and remove shared memory between 2 processes in PHP?
|
<p>I developed a way to make async tasks with PHP and it's working very well, until now.</p>
<p>The logic based in 3 extensions <a href="http://php.net/manual/en/book.pcntl.php" rel="noreferrer">PCNTL</a>, <a href="http://php.net/manual/en/book.posix.php" rel="noreferrer">POSIX</a> e <a href="http://php.net/manual/en/book.sem.php" rel="noreferrer">Semaphore</a>.</p>
<p>To have a full control of the master process and child process I must share the status of the task and the PID between them. These 2 variables are shared using <a href="http://php.net/manual/en/function.shm-attach.php" rel="noreferrer">shm_attach</a>, the fork uses <a href="http://php.net/manual/en/function.pcntl-fork.php" rel="noreferrer">pcntl_fork</a>.</p>
<p>The problem described in the title of this questions is related to the status of the task and the PID between them. These 2 variables are shared using <a href="http://php.net/manual/en/function.shm-attach.php" rel="noreferrer">shm_attach</a> method because there is no more space available to share create a <a href="https://gerardnico.com/wiki/linux/shared_memory" rel="noreferrer">shared memory</a>.</p>
<p>I use it for 2 moments:
At constructor to create the shared memory</p>
<pre><code><?php
//...
final public function __construct() {
self::$shmId = shm_attach((int) (ftok(self::$file, 'A') . self::$line), self::SHARED_MEMORY_SIZE);
$this->var_key_pid = $this->alocatesharedMemory(getmypid(), 112112105100); //112112105100;
$this->var_key_status = $this->alocatesharedMemory('PENDING', 11511697116117115); //11511697116117115;
}
</code></pre>
<p>And on the <code>run</code> method after forking the process</p>
<pre><code><?php
final public function run($parameters) {
//...
} else { //Frok process
ignore_user_abort(); //I dont know why but must be set again.
$sid = posix_setsid();
self::$shmId = shm_attach((int) (ftok(self::$file, 'A') . self::$line), self::SHARED_MEMORY_SIZE);
</code></pre>
<blockquote>
<p>NOTE: The code is a little extensive and I put it into a gist
<a href="https://gist.github.com/LeonanCarvalho/62c6fe0b62db8a478f502f84c5734c83" rel="noreferrer">https://gist.github.com/LeonanCarvalho/62c6fe0b62db8a478f502f84c5734c83</a></p>
</blockquote>
<p>I think I'm doing something wrong because even though I'm using <a href="http://php.net/manual/en/function.shm-detach.php" rel="noreferrer">shm_detach</a> and <a href="http://php.net/manual/en/function.shm-remove.php" rel="noreferrer">shm_remove</a> the process sometimes returns the error <strong>PHP Warning: "shm_attach" failed for key No space left on the device in</strong> when I try to attach a new shared memory.</p>
<p>It is happening because some shared memory is detached and not removed from Shared memory segments, its the result of command <code>ipcs -m</code> :</p>
<p><a href="https://i.stack.imgur.com/ldMAr.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ldMAr.png" alt="ipcs -m result"></a></p>
<p>The tasks are running for months before start doing this, so the one way to work around this problem I removed all shared memory identifiers with the command </p>
<pre><code>ipcrm --all=shm
</code></pre>
<p>But I think it's silently growing and for sure it going to happen again.</p>
<p>How to prevent it?</p>

Android Firebase : Second Connected Database not allowing auth in rules
|
<p>I've connected two Databases from the same firebase project like below.</p>
<pre><code> //init the default db;
FirebaseApp.initializeApp(this);
//init the second db;
FirebaseOptions.Builder builder = new FirebaseOptions.Builder();
builder.setApplicationId("id"); //Same as default
builder.setApiKey("key"); //Same as default
builder.setDatabaseUrl("https://second-db.firebaseio.com");
try {
FirebaseApp.initializeApp(this, builder.build(), "second-db");
} catch (IllegalStateException e) {
e.printStackTrace();
}
</code></pre>
<p>Getting Reference. </p>
<pre><code>public static DatabaseReference getSecondDbRef(String child) {
FirebaseApp app = FirebaseApp.getInstance("second-db");
return FirebaseDatabase.getInstance(app).getReference(child);
}
</code></pre>
<p>With the above, it works, but the rules in the second database don't seem to be getting auth. if I do.</p>
<pre><code> {
"rules":{
"users":{
"$uid":{
".read":"auth.uid !== null",
// ".read":true // This works, so the issue is auth
}
}
}
}
</code></pre>
<p>The read fails, even though the user is authenticated, also, this problem isn't there with the default database. Is there anything I'm missing with the init?</p>
<p>Ok, because of highlights below, here's the code as it is on the app.</p>
<pre><code> private static final String TEAMS_BD_ID = "second-db"
public void initFirebase() {
FirebaseApp.initializeApp(this);
FirebaseOptions.Builder builder = new FirebaseOptions.Builder();
builder.setApplicationId("appId"); // //Same as default
builder.setApiKey("key"); // //Same as default
builder.setDatabaseUrl("https://teams-db.firebaseio.com");//Second Db
try {
FirebaseApp.initializeApp(this, builder.build(), TEAMS_BD_ID);
} catch (IllegalStateException e) {

Rails: how to save a gem's class as a model in my database?
|
<p>I've been building a Google Tasks integration app and just switched to using the Google API Client (<code>gem 'google-api-client', '~> 0.34'</code>)</p>
<p>This gives me some classes that I'm really starting to like:</p>
<pre class="lang-rb prettyprint-override"><code>Google::Apis::TasksV1::Task
Google::Apis::TasksV1::TaskList
Google::Apis::TasksV1::Tasks # (for multiple records)
Google::Apis::TasksV1::TaskLists # (for multiple records)
</code></pre>
<p>These classes come with all the attributes I want and I'm thinking it would be nice to actually have these records in my database instead of what I'm doing now, which is HTTP requests with OAuth (using methods provided by the gem)</p>

<p>The items come back as structured classes! It's great!</p>
<p>However, there's a good amount of latency with every call. </p>
<p>I'm running these commands in jobs, but I'm also thinking about saving these to my database (postgresql) and just comparing <code>updated</code> timestamps instead of pulling the information every single time I need it.</p>
<p>So, here's my question:</p>
<h1>How can I take the class as-is and make it a model in my database?</h1>
<p>I want to be able to call <code>Google::Apis::TasksV1::Task.create(tasklist_attrs)</code> and other such model-type methods.</p>
<p>I have noticed that they don't respond exactly like my own classes (that inherit from <code>ActiveRecord::Base</code>):</p>
<pre class="lang-rb prettyprint-override"><code>2.6.3 :008 > User.new

JPA/ JPQL: How to use member-of with an hash-map
|
<p>I have problem using the member-of Statement. The problem I think is, that I made a mistake with the elements --> parameter.get("" i + anlass) but I don't know how to do it right.
Are there any other possibilities to ask if a certain element is an <code>@ManyToMany</code> List from another Object? </p>
<p>Here's my Code: </p>
<pre><code> /*My Beans:
@Entity
public class Rezept implements Serializable {

List<Anlass> anlässe = new ArrayList<>();
@ManyToMany(mappedBy="rezepten", cascade = {CascadeType.PERSIST})
List<Grundzutat> grundzutaten = new ArrayList<>();*/
//The method is in the RezeptBean
public List<Rezept> searchByFilters(List<Anlass> anlaesse, List<Grundzutat> grundzutaten, List<Allergie> allergien) {
// WHERE-Bedingungen für die Filteroptionen zusammenbauen
String select = "SELECT r FROM Rezept r";
String where = "";
Map<String, Object> parameters = new HashMap<>();
int i = 0;
for (Anlass anlass : anlaesse) {
i++;
parameters.put("" + i, anlass);
if (!where.isEmpty()) {
where += " AND ";
}
//Here I want to see if the element parameters.get("" + i) is member
of r.anlässe
where += ":" + parameters.get("" + i) + " MEMBER OF r.anlässe";
}
for (Grundzutat grundzutat : grundzutaten) {
i++;
parameters.put("" + i, grundzutat);
if (!where.isEmpty()) {
where += " AND ";
}
where += ":" + parameters.get("" + i) + " MEMBER OF r.grundzutaten";
}

SES Boost Mail Speed

Jquery incompatibility issue with Chrome
|
<p>I ran into a headache situation. When I checked the selection option (05/30/2012 EQ), I can't click select button to submit the action, but I am supposed to be able to click it. The issue happens with Chrome and I.E, but it is good with FF. I think it is a Jquery incompatibility issue. I attached some of my code as follows:</p>
<pre><code> function $recalcSelection($checkbox) {
$selectActionList.find("option").each(function() {
$optionLength = $table.find("td.actioncolumn input:checked").length;
if($optionLength <= 0) {
$(this).attr("disabled", true);
} else if($optionLength == 1) {
$(this).attr("disabled", false);
} else {
if(
$(this).val() == "editAppointment" ||
$(this).val() == "copyAppointment" ||
$(this).val() == "viewShowList" ||
$(this).val() == "viewScheduledTimes")
{
$(this).attr("disabled", true);
} else {
$(this).attr("disabled", false);
}
}
});
if($selectActionList.find("option:selected").attr('disabled')) {
$selectActionList.find("option:enabled").eq(0).attr("selected", true);
}
if($selectActionList.find("option:enabled").length <= 0) {
$selectActionButton.attr("disabled", true);
} else {
$selectActionButton.attr("disabled", false);
}
}
</code></pre>
<p>$selectActionButton is the submit button, and $selectactionlist is the select list. I tried to print ($selectActionList.find("option:enabled").length in Chrome, it is 0. But when I was printing it in FF, it is 7. Can anyone help me to figure out why? I would so appreciate it. thanks</p>

<p>Currently, I have 3 separate scatterplots that all you the same data set. After numerous attempts I still can't figure out how to put them together / link them. I know mine is a little more complicated because my axis aren't the same.
I've really been struggling with this, any help would be GREATLY appreciated as I need it for uni. Thank you!</p>

Unexpected static counter variable behaviour
|
<p>Lately I tried getting my head around the static keyword and here I attempt to simply use the static keyword for a variable declaration within a function. Like so:</p>
<pre><code>void counter()
{
static int counter = 0; //should be initialized only once and once only
counter++; //increment for every call of this function
}
</code></pre>
<p>I understand that due to the variable being static, it will live outside the function and therefore from wherever I decide to print out counter, it should give me the number of times the function <code>counter()</code> was called. So I did a simple test as shown:</p>
<pre><code>int main()
{
for(unsigned int i = 0; i < 10; i++){
counter();
}
std::cout << counter << std::endl;
return 0;
}
</code></pre>
<p>From this test I expected to get number 10... but instead the number of counts the code returned was 1. </p>
<p>Please, what am I missing here?</p>
<p>I found other submissions to "similar" issues such as this one:
<a href="https://stackoverflow.com/questions/10881410/static-counter-in-c">static counter in c++</a>
But they mostly revolve around the static keyword being used in classes.</p>

Update mysql data via json
|
<p>Hey all So I am able to update the records from a json url and put it into Mysql now I am trying to update the records and it only grabs 1 value and updates all the records to the new value so its updating the existing records with only 1 record here is what I am using</p>
<pre><code>$ApiLink = "JSON URL HERE";
$json_decode = (json_decode(file_get_contents($ApiLink), true));
$output = $json_decode["character_list"];
/************************************************/
$do_stuff = $dbh->prepare("UPDATE damage_given_vehicle SET veh_id=:veh_id, veh_name=:veh_name, veh_total=:total_value, veh_faction_nc=:veh_faction_nc, veh_faction_tr=:veh_faction_tr, veh_faction_vs=:veh_faction_vs WHERE character_number = :char_id");
foreach ($output as $key => $value) {
$character_id[$key] = $output[$key]["id"];
if (isset($output[$key]["stats"]["vehicle_kills"]["vehicle"])) {
$vehicle_kills[$key] = $output[$key]["stats"]["vehicle_kills"]["vehicle"];
foreach ($vehicle_kills[$key] as $row) {
$do_stuff->bindValue(':char_id', $update_id);
$do_stuff->bindValue(':veh_id', $row["id"]);
$do_stuff->bindValue(':veh_name', $row["name"]);
$do_stuff->bindValue(':total_value', $row["value"]);
$do_stuff->bindValue(':veh_faction_nc', $row["faction"]["nc"]);
$do_stuff->bindValue(':veh_faction_tr', $row["faction"]["tr"]);
$do_stuff->bindValue(':veh_faction_vs', $row["faction"]["vs"]);
$do_stuff->execute();
}
}
}
</code></pre>
<p>the database looks like this at first:</p>
<pre><code>key | id | name | value 1 | value 2 | value 3 | value 4 |
5428029729515051201 11 name_1 6 45 23 34
5428029729515051201 11 name_2 2 34 63 63
5428029729515051201 11 name_3 34 0 17 17
</code></pre>
<p>after I use the update script it turns those values into:</p>
<pre><code>5428029729515051201 11 name 34 0 17 17
5428029729515051201 11 name 34 0 17 17
5428029729515051201 11 name 34 0 17 17
</code></pre>
<p>if you are curious how the script enters the json data here you go:</p>
<pre><code>$stmt = $dbh->prepare("
INSERT INTO damage_given_vehicle (
character_number, veh_id, veh_name, veh_total,
veh_faction_nc, veh_faction_tr, veh_faction_vs)
VALUES(
:char_id, :veh_id, :veh_name, :total_value,
:veh_faction_nc, :veh_faction_tr, :veh_faction_vs)
");
foreach ($output as $key => $value) {
$character_id[$key] = $output[$key]["id"];
if (isset($output[$key]["stats"]["vehicle_kills"]["vehicle"])) {
$vehicle_kills[$key] = $output[$key]["stats"]["vehicle_kills"]["vehicle"];
foreach ($vehicle_kills[$key] as $row) {
$stmt->bindValue(':char_id', $character_id[$key]);
$stmt->bindValue(':veh_id', $row["id"]);
$stmt->bindValue(':veh_name', $row["name"]);
$stmt->bindValue(':total_value', $row["value"]);
$stmt->bindValue(':veh_faction_nc', $row["faction"]["nc"]);
$stmt->bindValue(':veh_faction_tr', $row["faction"]["tr"]);
$stmt->bindValue(':veh_faction_vs', $row["faction"]["vs"]);
$stmt->execute();
}
}
}

<p>How do I get it to update every array seperately, If I do a var_dump on any of the $row[""] they produce the array how it should be displayed but when it goes through and enters into mysql it only grabs 1 value </p>

Conditional merging with many variables
|
<p>I am wondering if there was a faster, more elegant data.table solution to my following question.</p>
<p>Suppose we have two datasets</p>
<pre><code>set.seed(1)
library(data.table)
DT1 <- data.table(income = runif(10, 0,1),
ID = 1:10)
DT2 <- data.table(height = runif(20,0,1),
weight = runif(20,0,1),
V1 = runif(20,0,1),
V2 = runif(20,0,2),
type = rep(c("Parents", "Children"),10))
DT2 <- DT2[order(type)][, ID := rep(1:10,2)]
</code></pre>
<p>The first dataset is a "household" level dataset with household identifiers given by ID, from 1:10.</p>
<p>There is a second dataset, <code>DT2</code> which has four variables for each parent and child, for each household ID. What I want to do is merge all the variables (height, weight, V1, V2) of the Parents and Children in each row/observation of DT1. So we would have eight variables to merge, four for the parents and four for the children.</p>
<p>To do so, I can simply write the following:</p>
<pre><code>
DT1[DT2[type == "Parents"], c("height_parents", "weight_parents",
"V1_parents", "V2_parents") := list(i.height, i.weight,
i.V1, i.V2), on = c(ID = "ID")]
DT1[DT2[type == "Children"], c("height_children", "weight_children",
"V1_children", "V2_children") := list(i.height, i.weight,
i.V1, i.V2), on = c(ID = "ID")]
</code></pre>
<p>The output looks like:</p>
<pre><code> income ID height_parents weight_parents V1_parents V2_parents height_children

</code></pre>
<p>Note that if I had many different "types" (here there is only two) and/or many different variables to merge (here there is only 4), the above would get quickly laborious and verbose. The dataset I am using has many different variables and types. Thus, I am looking to do this in a more efficient way. In particular, I want to be able to define a vector:</p>
<pre><code>merge_variables = c("height", "weight", "V1", "V2")
</code></pre>
<p>and in a data.table fashion, have all of these variables merge for both parents and children. I want the new variables to have an underscore in them with the types name (e.g.<code>height_parents</code> and <code>height_children</code>).</p>
<p>I hope I've communicated my request clearly.</p>
<p>Thanks!</p>

Keep prompt at bottom of screen for messaging app
|
<p>I'm trying to develop a CLI messaging app in C on mac for network programming practice but I'm not sure how to effectively manipulate the command line to make it usable. Currently the prompt will display "Enter a message: " but if a message comes in before the user finished typing their message something like this could happen:
"Enter a message: Hello wClient: I'm interupting youorld".</p>
<p>The solution I'd like to have would be to have the "Enter a message" prompt always at the bottom of the screen with the incoming and outgoing messages coming down from the top as you'd have in basically any messenger, though I have no idea how to glue something to the bottom of the terminal or how to visually affect the terminal in any way.</p>

how do I use variables from functions in other functions without putting the variable in the __init__ method of a class?
|
<p>I am new level coder, and I making a game that has different kinds of attacks, and I want to be able to combo into attacks seemlessly, but I cannot figure out how to make a delay between different attacks. So far I have tried to use to the same value that is the attack delay so that if the delay is reset, you can use a different attack, but it is not letting me do that because it doesn't know what the variable "now" is because I need "now" needs to be specifically in that function.

AWS Lightsail can't update Route53 for Let'sEncrypt certs
|
<p>I'm trying to get Let's Encrypt automatic cert update on a AWS Lightsail wordpress instance and Route53.</p>
<p>I used <a href="https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-using-lets-encrypt-certificates-with-wordpress" rel="nofollow noreferrer">these official instructions</a> for adding a SSL certs to a AWS Lightsail wordpress website.</p>
<p>Site SSL is working fine, but I was looking for a way to automate the re-issue and found the certbot plugin - <a href="https://certbot-dns-route53.readthedocs.io/en/stable/" rel="nofollow noreferrer">certbot-dns-route53</a></p>
<p>I created a separate AWS non-admin user just for the updates, and added the policy as suggested by the certbot official docs</p>
<pre><code>{

"Id": "certbot-dns-route53 sample policy",

],
"Resource": [

]
},
{
"Effect" : "Allow",
"Action" : [
"route53:ChangeResourceRecordSets"
],
"Resource" : [
"arn:aws:route53:::hostedzone/MYZONEID"
]
}
]
}
</code></pre>
<p>I placed the API access information in both a environment variable and ~/.aws.config file.</p>
<p>I executed the command -</p>
<pre><code> sudo certbot certonly --dns-route53 --dns-route53-propagation-seconds 30 --dry-run -d 'domain.
com,*.domain.com'
</code></pre>
<p>And I get the following error -</p>
<blockquote>

permissions for Route53 access</p>
</blockquote>
<p>I attempted a ~.aws/config & credentials file as well -</p>
<p>config-</p>

<p>credentials -</p>

</code></pre>
<p>I'm not sure how to get the lightsail instance of /i-00ff79ff762ac0576 assigned to the policy correctly. I've read through the config guide it links and it doesn't help.</p>

Babel config in a MERN app

<p>Can anyone give me a clue on how to get babel setup to work with a node app. I noticed that even when I run npm install in my console, I don't get a node_modules folder in my app. I used yarn to add dependencies to package.json, but don't seem to have the ability to generate an node_modules folder.</p>
<p><strong>Next attempt</strong></p>
<p>I then tried npm init and then npm upgrade (even though I use yarn for adding modules).</p>
<p>The output of npm upgrade is below, but I still don't end up with a node modules folder. I think the reason babel isn't working to recognise my import statements is because I don't have the module in my app. Does anyone know how to get a node modules file to be created in the setup? I thought that happened automatically.</p>

<p>What is problem in my code?</p>

Python TCP Payload Duplication - Passing through data to multiple endpoints concurrently
|
<p>this is my first post here!</p>
<p>My goal is to duplicate the payload of a unidirectional TCP stream and send this payload to multiple endpoints concurrently. I have a working prototype written in Python, however I am new to Python, and to Socket programming. Ideally the solution is capable of running in both Windows and *nix environments.</p>
<p>This prototype works, however it creates a new send TCP connection for each Buffer length (currently set to 4096 bytes). The main problem with this is I will eventually run out of local ports to send from, and ideally I would like the data to pass from each single incoming TCP stream to one single TCP stream out (for each endpoint). The incoming data can vary from less than 1024 bytes to hundreds of megabytes.</p>
<p>At the moment a new outgoing TCP stream is initiated for every 4096 bytes. I am not sure if the problem is in my implementation of threading, or if I have missed something else really obvious.</p>
<p>In my research I have found that select() could help, however I am not sure if it would be appropriate because I may need to process some of the incoming data and respond to the sending client for certain cases in the future.</p>
<p>Here is the code I have so far (some of the code variations I have tried are commented out):</p>
<pre><code>#!/usr/bin/python
#One way TCP payload duplication
import sys
import threading
from socket import *
bufsize = 4096
host= ''
# Methods:
#handles sending the data to the endpoints
def send(endpoint,port,data):
sendSocket = socket(AF_INET, SOCK_STREAM)
#sendSocket.setblocking(1)
sendSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
#sendport = sendSocket.getsockname
#print sendport
try:
sendSocket.connect((endpoint, port))
sendSocket.sendall(data)
except IOError as msg:
print "Send Failed. Error Code: " + str(msg[0]) + ' Message: ' + msg[1]
sys.exit()
#handles threading for sending data to endpoints
def forward(service, ENDPOINT_LIST, port, data):
#for each endpoint in the endpoint list start a new send thread
for endpoint in ENDPOINT_LIST:
print "Forwarding data for %s from %s:%s to %s:%s" % (service,host,port,endpoint,port)
#send(endpoint,port,data)
ethread = threading.Thread(target=send, args=(endpoint,port,data))
ethread.start()
#handles threading for incoming clients
def clientthread(conn,service,ENDPOINT_LIST,port):
while True:
#receive data form client
data = conn.recv(bufsize)
if not data:
break
cthread = threading.Thread(target=forward, args=(service, ENDPOINT_LIST, port, data))
cthread.start()
#no data? then close the connection
conn.close()
#handles listening to sockets for incoming connections
def listen(service, ENDPOINT_LIST, port):
#create the socket
listenSocket = socket(AF_INET, SOCK_STREAM)
#Allow reusing addresses - I think this is important to stop local ports getting eaten up by never-ending tcp streams that don't close
listenSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
#try to bind the socket to host and port
try:
listenSocket.bind((host, port))
#display an error message if you can't
except IOError as msg:
print "Bind Failed. Error Code: " + str(msg[0]) + ' Message: ' + msg[1]
sys.exit()
#start listening on the socket
listenSocket.listen(10)
print "Service %s on port %s is listening" %(service,port)
while True:
#wait to accept a connection
conn, addr = listenSocket.accept()
print 'Connected to ' + addr[0] + ':' + str(addr[1]) + ' on port ' + str(port)
#start new thread for each connection
lthread = threading.Thread(target=clientthread , args=(conn,service,ENDPOINT_LIST,port))
lthread.start()
#If no data close the connection
listenSocket.close()
service = "Dumb-one-way-tcp-service-name1"
ENDPOINT_LIST = ["192.168.1.100","192.168.1.200"]
port = 55551
listen(service,ENDPOINT_LIST,port)
</code></pre>
<p>I have looked into other libraries to try to achieve my goal, including using:</p>
<ul>
<li>Twisted </li>
<li>Asyncore </li>
<li>Scapy</li>
</ul>
<p>However I found them quite complicated for my modest needs and programming skill level.</p>
<p>If anyone has any suggestions on how I could refine the approach I have, or any other ways this goal could be achieved, please let me know!</p>

Can not find new elements after javascript append using chrome webdriver

<p>Here's the simple HTML generated from a c# dotnet core asp pages, application. I'm trying to get the number of input boxes from colorList div using a webdriver test. The initial count of two works, but once i simulate the clicking the button labeled "+" i still only get two, where i expected to get three. I've tried all kinds of different waits both implicit and explicit, but can't seem to get it to work. </p>

Intentional friend class redifinition and -fstack-protector
|
<p>I have been trying testing if multiple definition of a friend class in different <code>.cpp</code> files would work. To do that I defined a main class inside <code>main_class.hpp</code> file:</p>
<pre><code>class main_class
{
private:
int a;
int b;
int gimme_a()
{
return a;
}
public:
main_class(int a, int b) : a(a), b(b) {}
int gimme_b()
{
return b;
}
friend class main_class_friend;
};
</code></pre>
<p>Then I defined <code>main_class_friend</code> two times, firstly within <code>main_friend_class1.cpp</code> file:</p>
<pre><code>class main_class_friend
{
main_class c;
public:
main_class_friend() : c(10, 10) {}
int gimme_a()
{
return c.gimme_a();
}
int gimme_b()
{
return c.gimme_b();
}
};
</code></pre>
<p>and a corresponding public test function:</p>
<pre><code>void test1()
{
main_class_friend ff;
std::cout << "Gimme a: " << ff.gimme_a() << " and gimme b: " <<
ff.gimme_b() << std::endl;
}
</code></pre>
<p>and then I defined the second <code>main_class_friend</code> within <code>main_friend_class2.cpp</code> and a corresponding public test function:</p>
<pre><code>class main_class_friend
{
private:
main_class ca;
int c;
public:
main_class_friend() : ca(9 ,9), c(11) {}
int gimme_a()
{
return ca.gimme_a();
}
int gimme_b()
{
return ca.gimme_b();
}
int gimme_c()
{
return c;
}
};
void test2()
{
main_class_friend ff;
std::cout << "Gimme a: " << ff.gimme_a() << " and gimme b: " << ff.gimme_b()
<< " and gimme c: " << ff.gimme_c() << std::endl;
}
</code></pre>
<p>Finally I called <code>test1</code> and <code>test2</code> function inside main:</p>
<pre><code>int main()
{
test1();
test2();
return 0;
}
</code></pre>
<p>compiled the program (no errors from <code>g++</code>), and run it. The output was:</p>
<pre><code>Gimme a: 9 and gimme b: 9
*** stack smashing detected ***: ./a.out terminated
Aborted (core dumped)
</code></pre>
<p>What's really weird for me is that <code>a</code> and <code>b</code> were initialized by the constructor inside <code>main_friend_class2.cpp</code> and not the one from <code>main_friend_class1.cpp</code> where <code>test1</code> function is defined.</p>
<p>Then I found that stack smashing can be easily debugged when a program is compiled with <code>-fstack-protector</code> flag. So I compiled it once again and the output from the program was then:</p>
<pre><code>Gimme a: 9 and gimme b: 9
Gimme a: 9 and gimme b: 9 and gimme c: 11
</code></pre>
<p>so no more stack smashing problems, but both <code>test1</code> and <code>test2</code> functions use constructor from <code>main_friend_class2.cpp</code> file. </p>
<p>What's going on around here? I don't get it. Why there is a stack smashing error if there is no buffer overflow, because there isn't any buffer used?</p>
<p>My second question is: is there a way to define multiple times <code>main_class_friend</code>, but to use them in different files to make them "private" for the file inside which the class is used?</p>

sqlite not saving french accents like à as $agrave
|
<p>When i will save into my database "C'est tout à fait juste.", sqlite will remove the & from &agrave, becouse it can't maybe handle utf-8.</p>
<p>var sql += "INSERT INTO Test(TestId,Text) Values(1, "C'est tout à fait juste.");</p>
<p>I tried for every insert to replace the $agrave with à, but I think there will be a better solution.</p>
<p>Is there a better way to solve this?</p>
<p>Thanks for any help...</p>

OrientationSensor / Inclinometer weird, undocumented sensor reading jump when facing horizon
|
<p>I'm trying to upgrade an app of mine to use Windows 10 Mobile device sensors as a VR device for the pc (like Google Cardboard).
I'm experiencing a problem with the sensor readouts when the device changes from pointing below the horizon to above the horizon (happens for both landscape and portrait, however in this case only landscape is important). A small sketch:
<a href="https://i.stack.imgur.com/V2MUg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/V2MUg.png" alt="Switch over point causing major sensor reading change"></a></p>
<p>Raw sensor readouts (pointing downward):</p>
<p>Inclinometer Pitch: -000.677 , Roll: -055.380 , Yaw: +013.978</p>
<p>Now after changing to pointing upward:</p>
<p>Inclinometer Pitch: -178.550 , Roll: +083.841 , Yaw: +206.219</p>
<p>As you can see, all 3 values changed, by a significant amount. In reality only one axis should have changed, roll or pitch (depending on sensor orientation)</p>
<p>I'm 95% sure, this problem didn't exist in Windows Phone 8. I'm unable to find any documentation about this weird behaviour of the sensors and it's stopping me from creating Augmented Reality and Virtual Reality apps.</p>
<p>Here are 2 pictures of the problem:

<p>Position the phone as seen in step (1). Phone in landscape mode, camera facing slightly downward, screen facing slightly upward.</p>
<p>Change to step (2). You slightly tilt it forward, only one axis should change (in this case Inclinometer will show you only "Roll" changing. <strong>THIS IS CORRECT</strong>)</p>
<p>Change to step (3). You now tilt your phone back. As soon as the switch over point comes, where the camera is no longer facing the ground, but now the sky and the screen is now facing slightly downward, all 3 values change by a significant amount. Pitch will jump by about -180°, Roll will jump by about 90° additionally to the amount you actually changed, and Yaw will jump by about +180°. </p>
<p><strong>As long as the camera is ONLY pointing to EITHER the earth or the sky, the sensors behave fine! ONLY when switch from one to the other does this problem occur! (This scenario happens all the time with VR and AR, so this is a big problem)</strong></p>

Hibernate list mapping constraint violation
|
<p>These are my postresql tables :</p>
<pre><code>CREATE TABLE "user" (
"id" int4 NOT NULL,
"activated" bool NOT NULL DEFAULT True,
CONSTRAINT "user_pkey" PRIMARY KEY("id")
);
CREATE TABLE "user_data" (
"id" int4 NOT NULL,
"user_id" int4 NOT NULL,
"idx" int4 DEFAULT NULL,
"first_name" text NOT NULL,
"last_name" text NOT NULL,
CONSTRAINT "user_data_pkey" PRIMARY KEY("id")
);
</code></pre>
<p>My goal is to have in my "User" hibernate bean a direct reference to user's data, like this <code>List<UserData></code>. Here is my hibernate mapping :</p>
<pre><code><hibernate-mapping package="mypackage">
<class name="User" table="user">
<id name="id" type="long" column="id">
<generator class="sequence">
<param name="sequence">user_id_seq</param>
</generator>
</id>
<property name="activated" column="activated" type="boolean" />
<list name="data" table="user_data" cascade="all">
<key column="user_id" />
<list-index column="idx" />
<one-to-many class="UserData" />
</list>
</class>
<class name="UserData" table="user_data">
<id
name="id"
type="long"
column="id">
<generator class="sequence">
<param name="sequence">user_data</param>
</generator>
</id>
<many-to-one name="user" column="user_id" class="User" />
<property name="firstName" column="first_name" type="text" />
<property name="lastName" column="last_name" type="text" />
</class>
</hibernate-mapping>
</code></pre>
<p>I ran some tests. When I add a new "UserData" to my list and then execute <code>session.saveOrUpdate(myUser)</code> it works, but when I remove an entry from my list and execute the same line, it throws <code>ERROR [JDBCExceptionReporter] ERROR: null value in column "user_id" violates not-null constraint</code> just after telling me that <code>batch update user_data set user_id=null, idx=null where user_id='20' and id='46' was canceled</code></p>
<p>What is the right usage of this type of mapping? Thank you</p>
<p><strong>EDIT:</strong> Adding "inverse=true" isn't adapted to my usage because I need my update on user trigger an update on UserData. Again, maybe I didn't understand the right usage of this type of usage.</p>

CSS Hover and Display Inline Block not working properly
|
<p>Problem is when I hover, the overlay affects all the items, i would like it to do one at a time, not all at once and also I can't get the display to show Inline-Block, items seem to be taking up the whole row, once it's fixe i know i will have to adjust the figcaption because ideally that would need to be centered under each image... anything helps.
THanks!</p>

React - Input fields not editable even after I set the state

I am using props to show an event OR and empty event if there is no props (no event selected). </p>

Cannot make TextView's change color while user types
|
<p>I'm very very new to android dev, but I really enjoy it :) I am wanting to make a calculator app for a game I play to work out how long it'll take to get from level a to level b using the various methods. I'm doing pretty good with it so far, but now have encountered this error which is reallllly bugging me.<br>
I want to turn my text color to red if they input a number thats lower than the required experience to use ingame. For example, mahogany logs require 400000xp to be able to use, so if they enter <400000 I want the TextView with mahogany logs to turn red. Hope I made sense haha :) currently when i enter any number they all just change red and dont change with user input :(any help would be appreciated! :) Here is a screenshot of the app interface so you can see what I mean <a href="https://puu.sh/xdRfZ/a4651025d0.png" rel="nofollow noreferrer">https://puu.sh/xdRfZ/a4651025d0.png</a></p>

Deploying Jenkins Sectioned View Plugin extension

<p>I want to create new view for Sectioned View Plugin for Jenkins. How should I deploy my extension? I was trying to deploy it as new plugin in .jpi file but it didn't work. Where should I put my class/jar/jpi (I don't know which is right) file?</p>
<p>UPD: I tried to put jar to \jenkins\plugin\sectioned-view\WEB-INF\lib directory and it works but I doubt it's a right way to deploy that extension</p>
<p>UPD2: When I try to deploy extension as a new plugin I get these exception on startup:</p>

<p>According to the script, we just merged the script not to face conflicts/clashes for stage and development while deployment. Previously, we having each docker files for each environment(stage and developer). Now I want to merge the dockerfile also, I merged, but the dockerfile is not fetching. Having clashes (warning shows after pipeline succeeds) in Kubernetes. I don't know how to clear the warning in Kubernetes. I'll enclose the docker file which I merged.</p>

<p>the last line, we used before,</p>
<pre><code>ENTRYPOINT ["java","-Dspring.profiles.active=development","-jar","/app/patient-service.jar"] -for developer dockerfile
ENTRYPOINT ["java","-Dspring.profiles.active=stage","-jar","/app/patient-service.jar"] - for stage dockerfile
</code></pre>
<p>At the time, its working fine, I'm not facing any issue on Kubernetes. I'd just add environment variable to fetch along with whether development or stage. You can check ,my script after the docker build. After adding the variable only, we began facing the clashes. Please help me to sort this out. Thanks in advance.</p>

Video Streaming: Could not deserialize image after using pickle
|
<p>I'm trying to create a video streaming application, which has 3 components:</p>
<ol>
<li>An streaming application which streams via UDP the image received from camera </li>
<li>The UDP server which reads for data, puts it in a local file</li>
<li>HTTP Server, with a /cam.mjpg API, whose handler reads every 0.05 seconds from that pickle file, and transmits it (content type multipart)</li>
</ol>
<p>I'm getting the following error:</p>

<p>I believe the data I'm sending could be sent as a numpy array, not too sure, please suggest.</p>
