d19202 | test | Use .toUpperCase() on each letter and compare it to the letter capitalized, if it is the same, then it's in capital. Otherwise it's not, you don't actualy need any databases. Try following this code:
client.on("message", async msg => {
let sChannel = msg.guild.channels.find(c => c.name === "guard-log");
if (msg.channel.type === "dm" || msg.author.bot || msg.content.length < 15) return;
// Use `||` (OR) to make it cleaner.
let non_caps, caps;
// Create the variables.
for (x=0;x<msg.content.length;x++) {
if (msg.content[x].toUpperCase() === msg.content[x]) caps++;
else non_caps++;
}
// `caps` is the amount of capital letters, while `non_caps` is the amount of non-capital letters. This checks for each letter of the message and gets the amount of `caps` and `non_caps`.
const textCaps = (caps / message.content.length) * 100;
// Gets a percentage of the capital letters.
if (textCaps >= 60 && !msg.member.permissions.has('ADMINISTRATOR')) {
// If the capital letters is over or equals to 60% of the message,
// and if the user isn't an ADMINISTRATOR, then...

.addField('Engellenen mesaj', "```" + msg.content + "```", true)
.setTimestamp()
sChannel.send(embed);
msg.delete(); // Deletes the capped message.
return msg.reply(`fazla caps kullanıyorsun.`)
// `message.reply()` mentions the user that sent the message and is cleaner.
.then(m => m.delete(5000))

Do be careful, since this will delete the message if they put too much caps, including them quoting someone, whether they mean it or not.

d19204 | test | The segment registers get initialized by the OS. For most modern OSes they point to the same Segment that is referring to the whole address-space, as most OSes use a Flat Memory model (i.e. no segmentation).
The reason for not using only ds (the default for almost all memory accesses) here is that the operands for movs are implicit, and made sense in times of DOS.
In times of DOS (Real Mode), there was an actual use of them, since registers where limited to 16Bit and so limited to 64K of address-space. The address space(1M) was divided into overlapping 64K segments. | unknown | |

d19210 | test | Each time the microcontroller starts up it is seeing exactly the same internal state as any other time it starts up. This means its output will always be the same regardless of any algorithm you might use.
The only way to get it to produce different behaviour is to somehow modify its state at startup by introducing some external information or by storing state between startups. Some ideas for how to do the first option might be to measure the duration of a user key press (if your system has buttons) or sensing a temperature or other external input and using this to seed the algorithm. However the simplest option is probably to just store a counter in EEPROM that is incremented after each startup and use this to generate the seed. | unknown | |
d19211 | test | You could break up text into two arrays of sentences and then use a function like the similar_text function to recursively check for similar strings.
Another idea, to find outright pauperism. You could break down text into sentences again. But then put into a database and run a query that selects count of index column and groups by sentence column. If any results comes back greater than 1, you to have an exact match for that sentence. | unknown | |
d19212 | test | You can create a custom directive like bellow
import { Directive, HostListener } from '@angular/core';
@Directive({
selector: '[scroller]'
})
export class ScrollerDirective {
@HostListener('scroll') scrolling(){
console.log('scrolling');
}
@HostListener('click') clicking(){
console.log('clicking...');
}
constructor() { }
}
And then assuming you have a html template like
<div class="full-width" scroller>
<div class="double-width"></div>
</div>
use the following css
.full-width{
width: 200px;
height: 200px;
overflow: auto;
}
.double-width{
width:400px;
height: 100%;
}
the console will print "scrolling" on running the app if you move the horizontal scroll bar.
Here the key is that - the scoller directive should be in the parent not in the child div.
A: @HostListener('document:wheel', ['$event.target'])
public onWheel(targetElement) {
console.log()
}
A: Set (scroll)="yourFunction($event)" within the template at the corresponding element.
A: You could do it by the following code as well:
import { HostListener} from "@angular/core";
@HostListener("window:scroll", [])
onWindowScroll() {
//we'll do some stuff here when the window is scrolled
}
A: For those who were still not managed to figure this out with any of above solutions, here's a running code that is tested on Angular 12
@HostListener('document:wheel', ['$event.target'])
onScroll(): void {
console.log("Scrolling");
}
A: In angular 10 and above, when listening to window events do the following:
import { HostListener } from '@angular/core';
@HostListener('window:scroll', ['$event']) onScroll($event: Event): void {
if($event) {
console.log($event));
}
}
A: Assuming you want to display the host scroll (and not the windows one) and that you are using angular +2.1
@HostListener('scroll', ['$event']) private onScroll($event:Event):void {
console.log($event.srcElement.scrollLeft, $event.srcElement.scrollTop);

A: The called function within onclick has to be a string, you can't reference variables directly in it.
onclick="fnUpdate(\"<s:property value='roleTypeUid'/>\");"

d19214 | test | If you really want to understand why you can't enter while() {...}, you need to consider the following.
First, your call to odbc_connect(), which expects database source name, username and password for first, second and third parameter. It should be something like this (DSN-less connection):
<?php
...
$connStr = odbc_connect("Driver={MySQL ODBC 8.0 Driver};Server=server;Database=database;", "user", "pass");
if (!$connStr) {
echo 'Connection error';
exit;
}
...
?>
Second, check for errors after odbc_exec():
<?php
...
$rs = odbc_exec($connStr, $query);
if (!$rs) {
echo 'Exec error';
exit;
}
...
?>
A: you can do it with just SQL check it here, like:
INSERT INTO test_data(cardnumber, peoplename, creditlimit, cbalance, minpay)
SELECT cardnumber, peoplename, creditlimit,
ROUND(cbalance,2) as cbalance, minpay from IVR_CardMember_Info
where cardnumber not like '5127%' | unknown | |
d19215 | test | You could loop through an array of file extensions and check them i've made a sample script to show what i mean listed below
$array = array('.jpg','.png','.gif');
foreach($array as $key => $value){
$file = 'images/img_' . $post->_id . $value; // images/img_1.jpg
if (file_exists($file) && is_file($file)) {
$filefound = '<img src="' . $file . '" class="img-responsive" />';
}
}
if(isset($filefound)){
echo $filefound;
}else{
echo '<img src="images/default.gif" class="img-responsive" />';
}
A: The most efficient way to do this is probably to store the extension in the database, that way you're not scanning your file system for matches.
However, you could also use the glob();; function and check if results has anything.
$result = glob('images/img_' . $post->_id . '.*');
If you want to further narrow down your extension types you can do that like this:
$result = glob('images/img_' . $post->_id . '.{jpg,jpeg,png,gif}', GLOB_BRACE)
New code might look something like this (untested but you get the idea):
$result = glob('images/img_' . $post->_id . '.{jpg,jpeg,png,gif}', GLOB_BRACE);
if(!empty($result)) {
//show the image
echo '<img src="' . $result[0]. '" class="img-responsive" />';
} else {
// show default image
echo '<img src="images/default.gif" class="img-responsive" />';
}
A: It is obvious that your script will check only for .jpg not for others because you have written statically the file extension.
$file = 'images/img_' . $post->_id . '.jpg';
^
Now Make change in this line to make available the extension dynamically. I am supposing that you are storing the image name with extension than:
$file = 'images/img_' . $post->_id . $post->image_name;
Note : $post->image_name should be like :
$post->image_name = abc.png (image_name.extension); | unknown | |
d19216 | test | Use html_entity_decode() instead of html_entity_encode()
A: If you check the html_entity_decode() manual:
You might wonder why trim(html_entity_decode(' ')); doesn't
reduce the string to an empty string, that's because the ' '
entity is not ASCII code 32 (which is stripped by trim()) but ASCII
code 160 (0xa0) in the default ISO 8859-1 characterset.
You can nest your html_entity_decode() function inside a str_replace() to ASCII #160 to a space:
<?php
echo str_replace("\xA0", ' ', html_entity_decode('ABC XYZ') );
?>
A: Use htmlspecialchars_decode is the opposite of htmlspecialchars.
Example from the PHP documentation page:
$str = '<p>this -> "</p>';
echo htmlspecialchars_decode($str);
//Output: <p>this -> "</p>
A: html_entity_decode() is the opposite of htmlentities() in that it converts all HTML entities in the string to their applicable characters.
$orig = "I'll \"walk\" the <b>dog</b> now";
$a = htmlentities($orig);
$b = html_entity_decode($a);
echo $a; // I'll "walk" the <b>dog</b> now
echo $b; // I'll "walk" the <b>dog</b> now
A: I know my answer is coming in really late but thought it might help someone else. I find that the best way to extract all special characters is to use utf8_decode() in php. Even for dealing with or any other special character representing blank space use utf8_decode().
After using utf8_decode() one can manipulate these characters directly in the code. For example, in the following code, the function clean() replaces with a blank. Then it replaces all extra white spaces with a single white space using preg_replace(). Leading and trailing white spaces are removed using trim().
function clean($str)
{
$str = utf8_decode($str);
$str = str_replace(" ", "", $str);
$str = preg_replace("/\s+/", " ", $str);
$str = trim($str);
return $str;
}
$html = " Hello world! lorem ipsum.";
$output = clean($html);
echo $output;

d19222 | test | A: don't add stuff to the end of the content description. It is an accessibility violation and in almost ALL circumstances just makes things less acessible (will explain more later).
B: A lot of contextual things are communicated to TalkBack users via earcons (bips, beeps, etc), you may just not be noticing.
C: Yes, this is confusing and difficult to determine, no images are not announced, though I think this is for good reason. For example, an image with a click listener may just be a fancy styled button. In iOS there are traits for you to change for this, Android has omitted this highly useful feature, so we're stuck with odd workarounds. The ideal solution would be for the Accessibility APIs to allow the developer to communicate this information.
As for links, typically inline links in text views are announced (basically anything android detects and underlines automatically), but otherwise are not. So, in practice A LOT of links are missed.
Now, as for when you should/should not supply this information yourself. If unsure, just don't and you'll obtain a reasonably high level of accessibility by following the above guidelines. In fact, any of the considerations below are really just fighting the Android OS limitations, and are their problem! However, the Android Accessibility Ecosystem is very weak, and if you want to provide a higher level of accessibility, it is understandable, however, difficult! In your attempts you can actually end up working against yourself. Let me explain:
In Accessibility there is a line between providing information and consistency. By adding contextual information to a content description you are walking along this line. What if Google said "We're not going to share contextual information, add it yourself!".
You would have buttons in music players across different music playing apps that announce in TalkBack like this:
App1: "Play, Button"
App2: "Play, Actionable"
App3: "Play, Clickable"
Do we have consistency here? Now a final example!
App4: "Play, Double Tap to click if you're on TalkBack, Hit enter if you're a keyboard user, use your select key for SwitchAccess users....."
Notice how complicated App4's Play Button is, this is illustrating that the information that TalkBack is using is NOT JUST FOR TALKBACK. The accessibility information from you app is consumed by a multitude of Accessibility services. When you "Hack" contextual information onto a content description, sure it might sound better for a TalkBack user, but what have you done to Braille Back users? To SwitchAccess users? In general, the content description of an element should describe the element, and leave contextual information for TalkBack to calculate/users to figure out given proximity to other controls.
TO ANSWER YOUR TWO PARTICULAR ISSUES (Images and Links):
What I recommend for images is in the content description make it obvious that the thing your describing is an image.
Let's say you have a picture of a kitten.
BAD: A kitten, Image
Good: A picture of a kitten.
See here, if TalkBack fails to announce this as an image (which it will) the user still gets the idea that it is a picture. You have added contextual information to the content description in a way that has ACTUALLY BETTER DESCRIBED THE CONTROL. This is actually the most accessible solution! Go figure.
Links:
For links this gets a bit tricky. There is a great debate in Accessibility about what constitutes a link vs a button. In the web browser world, this is a good debate. However, in native mobile I think we have a very clear definition:
Any button that when activated takes you away from your current Application Context, is a link.
The fact that the Context (Capital C Context!!!) is going to change significantly when a user interacts with a control is EXCEPTIONALLY important information.
TalkBack fails to recognize links A LOT, and as such, for this very important piece of information, if you find that TalkBack is not sharing this information, go ahead and append ", link" to your content description for this element. THIS IS THE ONLY EXCEPTION TO THIS RULE I HAVE FOUND, but believe it is a good exception. Reason being, YES it does add a violation or two for other Assistive Technologies, but it conveys important enough information to justify doing so. YOU CANNOT create a WCAG 2.0 compliant application of reasonable complex User Interface using the Android Accessibility APIs. They have too many limitations, you simply can't do everything you need to do to accomplish this without "hacks". So, we have to make judgement calls sometimes. | unknown | |

Another example is to do the following :

d19227 | test | I have found the solution, I should just add this tag to the SmtpAppender:
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
A: Try using:
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
...
<threshold value="WARN"/>
...
</appender>
(or threshold value="ERROR" since you say you want to limit to Error and Fatallevels) rather than:
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
...
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="WARN"/>

d19228 | test | The actual problem is you're trying to simultaneously read real status and simulate press/release the same mouse button.
The only way to resolve this problem is (as you have suggested) to bind fire to additional key.
For example, in the game config you assign both left mouse button and keyboard key combination CtrlP to "Fire". Please note that P without a modifier must be NOT assigned to any action in the game.
And your script would be the following:
EnablePrimaryMouseButtonEvents(true)
function OnEvent(event, arg)
if event == "MOUSE_BUTTON_PRESSED" and arg == 1 and IsModifierPressed("lctrl") then
repeat
Sleep(15)
PressKey("P")
Sleep(15)
ReleaseKey("P")
until not IsMouseButtonPressed(1) or not IsModifierPressed("lctrl")
end
end | unknown | |
d19229 | test | Basically I don't think this is possible with any widely available compiler.
You would have to use program-counter relative addressing for all data in flash, but absolute addressing for addresses in RAM. While the ELF for ARM specification has these kinds of relocations, I don't think any compiler knows how to do generate code to use them. Also, it wouldn't know which to use in each case given that what is in flash and what is in RAM isn't decided until the linker stage.
One solution (which I have used in production) is to compile all your sources once but link them twice with two different linker scripts with absolute addresses. You will then have to distribute a double-sized update image, only half of which is used on any occasion.
Alternatively if you only want to have one image, then you need to do a double-shuffle. Have your working image write the new image to one area of internal flash, then reboot and have the bootloader copy it from there to the working location. You couldn't run it from the temporary location because the embedded addresses would be wrong (this is identical to your current solution but only uses the internal flash).
A: You build the application as position independent, the startup code looks at the address it is executing from and adjusts the GOT before it launches into main() or whatever your C entry point is. Can certainly do this with gnu tools, I assume llvm supports position independent as well.
Now you can only boot from one place and that is common to both paths so you do know which path you are taking because you have to create a non-volatile scheme to mark which path to try first or which path is the most recent. There are various ways to do that, too broad to answer here. That code can do the GOT thing just like a normal program loader would for an operating system, or each application can patch itself up before calling compiled code, or can do a hybrid.
You can have the application run in sram instead of from flash and the single entry point code can copy whichever one is the current one to ram, and you do not need position independence you link for ram and either can be a copy and jump.
You can link two versions of each application and part of the update process is to in some way (many ways to do it, too broad for here) determine which partition and write the one linked for that partition, then the common entry point can simply branch to the right address.
Some mcus have banked flashes and a way to put one out front, you can buy one of those products.
The common code can live in each image just in case and the A code assumed to be at the entry point for the chip will be the real bootloader that determines which partition to use and make adjustments as needed.
Your chip might have an mmu and you can remap whichever into the same address space and link for that address space.
Not only is this doable this is not complicated, there are too many ways to do it to describe and you have to simply pick the one you want to implement and maintain. The chip may or may not help in this decision. If you are already a bare-metal programmer then dealing with startup code and PIC and the GOT, and stuff are simple not scary.
What does GOT mean. global offset table, a side effect of how at least gcc/binutils work. With position independent code.
Just use the tools, no target hardware necessary....

1c: 00000000 .word 0x00000000
So the variable x is in .data the code is in .text, they are separate segments so you cannot make assumptions when compiling a module the pieces come together when linking. So this code is built so that the linker will fill in the value that is shown in this output as the 1c address. The address of x is read using that pc-relative load, then x itself is accessed using that address to do the x++;
lbounce and fbounce are not known to this code they are external functions so the best the compiler can really do is create a branch link to them.
Once linked:
00000010 <notmain>:

2c: 20000000 andcs r0, r0, r0
Per the linker script .data starts at 0x20000000 and we only have one item there so that is where x is. Now fbounce is too far away to encode in a single bl instruction so there is a trampoline or veneer created by the linker to connect them
00000030 <__fbounce_veneer>:

Note that is 0x80000000 with the lsbit set, the address is 0x80000000 not 0x80000001 look at the arm documentation (the lsbit means this is a thumb address and tells the bx instruction logic to go to or remain in thumb mode, then strip that bit off and make it a zero. Being a cortex-m it is always thumb mode if you have a zero there then the processor will fault because it does not have an arm mode, the tool generated that properly).

Now it takes all of this to increment x. It is using a pc-relative offset in the literal pool at the end of the function to get from where we are to the GOT in .data. (important thing to note that means of you move .text around in memory you also need to move .data to be at the same relative offset for this to work). Then it has to do those math steps to get the address of x then it can do the read modify write.
Also note that the trampoline doesn't change still has the hard-coded address for the section that contains fbounce, so this tells us that we cannot move fbounce as built.
Disassembly of section .data:
20000000 <x>:
20000000: 00000009 andeq r0, r0, r9
Disassembly of section .got:
20000004 <.got>:
20000004: 20000000 andcs r0, r0, r0
So what is a GOT? It's a global offset table, in this trivial example there is this data item x in .data. There is a global offset table (okay correcting a statement above the .got section needs to be in the same place relative to .text for this to work as built, but .data can move and that is the whole point. .got for this to work needs to be in sram (and naturally that means a proper bootstrap needs to put it there just like .data needs to be placed from flash to sram before the C entry point).
So if you wanted to move the .data to some other address in memory because you are copying it from flash to a different address than it was linked for. You would need to go through the global offset table and modify those addresses. If you think about the position dependent, every function every instances of the global variable x, there will be that word in the literal pool after all the functions that access it, in places you cannot unravel. you would have to know the dozens to hundreds of places to modify if you wanted to move .data. With this solution you need to know where the GOT is and update it. So if instead of 0x20000000 you put it at 0x20008000 then you would go through the got and add 0x8000 to each entry before you launched this code or at least before the code touches any .data item.
And if you wanted to only move .text then at least as I have built this here, and not .data, then you need to move/copy the .text to the other address space and copy .got to the same relative address but not modify the got.
In your case you want to execute from two different address spaces but not move .data. So ideally need to get the tools to
have a fixed location for the .got which I did not dig into, exercise for the reader. If you can get the .got to be fixed and
independent of the location of .text then a single build of your program can be executed from two different flash locations without any modification. Without the need for two separately linked, binaries, etc.
.got : { *(.got*) } > rom
Done.
Disassembly of section .data:
20000000 <x>:
20000000: 00000009 andeq r0, r0, r9
Disassembly of section .got:
00000048 <.got>:
48: 20000000 andcs r0, r0, r0
that means the GOT is in the flash, which would end up being in the big binary blob that would get programmed in either flash location in the correct relative position.
So my fbounce was for demonstration.
If you build position independent and there is not enough flash to worry about the veneer, so a single binary can be created that will execute from two different flash locations without modification.
Thus the term position independent code. But this is the trivial part of your problem, the part that takes little effort (took me a few minutes to see and solve the one issue I had). You still have other issues to solve that can be solved dozens of ways and you have to decide, design, and implement your solution. Way too broad for Stack Overflow. | unknown | |
d19230 | test | Replace this
for var i = 0; i <= inputString.count; ++i
with this:
for var i = 0; i < inputString.count; ++i
Arrays are zero indexed. That means the first element has the index 0. The second element has index 1. ... . The last element has the index array.count-1.
A: @dasdom is correct. but here is a more Swift-y way to do it:
// input string
var input = "ooooxxxxxxxoxoooxoxo"
// difference between number of x's and number of o's
var diff = 0
// perform this function for each character in `input.characters`:
input.characters.forEach {
switch $0 // $0 is the argument to our function (unnamed)
{
case "x": diff += 1 // x's are +1
case "o": diff -= 1 // o's are -1
default: fatalError() // we expect only 'x' or 'o'... if we get something else, just crash
}
}
// use the ternary (?:) operator to print the answer.
// (<result> = <condition> ? <if-true value> : <if-false value>)
print( diff == 0 ? "equal" : "not equal" )
A shorter version, inspired by @Eendje's answer :)
print( input.characters.reduce(0) { $0 + [ "x":1, "o":-1 ][ $1 ]! } != 0 ? "not" : "", "equal" )
A: While everyone is giving you an alternative, I thought this would be a nice addition as well:
var input = "xxxxxoxoooxoxo"
You can get the count by using filter:
let xCount = input.characters.filter { $0 == "x" }.count
let oCount = input.characters.filter { $0 == "o" }.count
print( xCount == oCount ? "equal" : "not equal" )
In your case, using reduce would be more efficient and it's shorter:
let result = input.characters.reduce(0) { $0 + ($1 == "x" ? 1 : -1) }
print(result == 0 ? "equal" : "not equal") // not equal
This is only if you're sure input only contains x and o. If not, then you'll have to change the evaluation to:
{ $0 + ($1 == "x" ? 1 : $1 == "o" ? -1 : 0) }
A: You are enumerating pass the range of the array. Use this instead.
for var i = 0; i < inputString.count; ++i {
Or you can use this more idiomatic code:
var input = "xxxoxoooxoxo"
var xString = 0
var oString = 0
for c in input.characters {
if c == "x" {
xString++
}
else if c == "o" {
oString++
}
}
if oString == xString {
print("equal")
}
else {
print("Not Equal")

d19231 | test | I thought I would update how I resolved the issue in case someone is facing the same issue.
There are number of things I did:
*
*Updated package.config as some of the packages were not using 4.6.1. I'm not sure how it worked until a certain point in time.
*Deleted local repo. Cloned the code from the repository, built the solution, and tested if the local instance is working. At this point, it was not.
*I noticed that the solution was compiling and producing libraries but the libraries were not copied into the \bin\Debug folder even though the output path was set to bin\Debug folder. So I updated the properties to change the output path to \bin, rebuilt the solution, and then changed the path back to bin\Debug and rebuilt it again. The local instance launched without any issues this time.
*Added the new webform (.aspx) file again and rebuilt the solution. This time the local instance launched without any issues. | unknown | |

I've used rank instead of row number, as two identical claim counts will produce a rank value the same. Rank will then skip the next rank (two 999 claim counts will each rank 1, a 998 claim count will rank 3. If you want it to rank 2 use dense_rank)
Let me know if you get any errors with this, as the only thing I'm not certain will work out is the subselect that retrieves the top 3 pracs. That can be done with a left join instead (which i have greater confidence in) | unknown | |

View v = (View)d.getWindow().findViewById(android.R.id.custom).getParent();
v.setBackgroundColor(Color.RED);
This picture means that customPanel should have some paddings, or custom should have non-zero layout params or something else. After checking those attributes which were equal to zero I tried to test minimumHeight of the customPanel and got 192 on xxhdpi or 64dp. This setting cause the frame to be larger than a nested custom view.
I haven't figured out where this setting is applied, but here is the workaround:
AlertDialog d = builder.create();
d.show();
View v = (View)d.getWindow().findViewById(android.R.id.custom).getParent();
v.setMinimumHeight(0);
Tested on API 18,19.

The layout:

</FrameLayout>
The android:minHeight="48dp" for contentPanel and customPanel are causing the unwanted blank space.
Unwanted space dialog
What I did is:
alertDialog.SetView(view);
alertDialog.show();
...
View customPanel = (View) view.getParent().getParent();
if (customPanel != null)
customPanel.setMinimumHeight(0);
View contentPanel = (View) alertDialog.findViewById(android.R.id.message).getParent().getParent().getParent();
if (contentPanel != null)
contentPanel.setMinimumHeight(contentPanel.getMinimumHeight() * 2 / 3);
Result:
Blank space removed

You could copy your layout in res/layout-vXX and set a specific (negative) margin. | unknown | |
d19245 | test | Yes, there is a way to use this inside your IIFE's, you can bind the thisValue with bind() before calling the IIFE.
(function() {
this.css('color', '#f00')
}).bind($('.' + c))();
A: You can use bind() or call() or apply() and pass 'this' through them as your scope changed for 'this'...
It's always a good practice using these functions in javascript, rather then attach it to the function...
The best option is call for your code...
(function() {
this.css('color', '#f00')
}).call($('.' + c));
Also using click handler in your javascript, make your code much cleaner and can make your coding structure better, you also can use multiple selection in jQuery to keep HTML clean if needed more selectors handle this function... | unknown | |

d19249 | test | This is a client error because the client specified a restaurant_id that didn't exist.
The default code for any client error is 400, and it would be fitting here too.
There are slightly more specific client error codes that might work well for this case, but it's not terribly important unless there is something a client can do with this information.
*
*422 - could be considered correct. The JSON is parsable, it just contains invalid information.
*409 - could be considered correct, if the client can create the restaurant with that specific id first. I assume that the server controls id's, so for that reason it's probably not right here.
So 400, 422 is fine. 500 is not. 500 implies that there's a server-side problem, but as far as I can tell you are describing a situation where the client used an incorrect restaurant_id. | unknown | |
d19250 | test | Your configuration is incorrect. cakePHP attempts to send the e-mail via smtp to your localhost.
Most likely you do not have an MTA (ie. exim, dovecot) installed locally and the request gets dropped. This should be visible as an error in you logs (if enabled).
An easy solution is to change the configuration to a working email service for testing, for example Gmail.
Example:
Email::configTransport('gmail', [
'host' => 'smtp.gmail.com',
'port' => 587,
'username' => '[email protected]',
'password' => 'secret',
'className' => 'Smtp',
'tls' => true

Note that the host and port point to Gmail. This example is indicative and was taken from the official documentation.

d19253 | test | You ask for "if any element in the list is greater than x". If you just want one element, you could just find the greatest element in the list using the max() function, and check if it's larger than x:
if max(list) > x:
...
There's also a one-liner you can do to make a list of all elements in the list greater than x, using list comprehensions (here's a tutorial, if you want one):
>>> x = 22
>>> list = [10, 20, 30, 40]
>>> greater = [i for i in list if i > x]
>>> print(greater)
[30, 40]
This code generates a list greater of all the elements in list that are greater than x. You can see the code responsible for this:
[i for i in list if i > x]
This means, "Iterate over list and, if the condition i > x is true for any element i, add that element to a new list. At the end, return that new list."
A: Use any, Python's natural way of checking if a condition holds for, well, any out of many:
x = 22
lst = [10, 20, 30] # do NOT use list as a variable anme
if any(y > x for y in lst):
# do stuff with lst
any will terminate upon the first truthy element of the iterable it is passed and, thus, not perform any spurious iterations which makes it preferable to max or list comprehension based approaches that have to always iterate the entire list. Asymptotically however, its time complexity is, of course, still linear.
Also, you should not shadow built-in names like list.
A: You could use filter and filter your list for items greater than 22, if
the len of this filtered list is > 0 that means your original list contains a value larger than 22
n = 22
lst = [10,20,30]
if len(list(filter(lambda x: x > n, lst))) > 0:
# do something to lst
A: List comprehension would suit your use case.
In [1]: x=22
In [2]: l=[10,20,30]
In [3]: exist = [n for n in l if n > x]
In [4]: if exist:
...: print "elements {} are greater than x".format(exist)
...:
elements [30] are greater than x
If your list is very long, use generator so that you do not have to iterate through all elements of the list.
In [5]: exist = next(n for n in l if n > x)
In [6]: if exist:
print "Element {} is greater than x".format(exist)
...:
Element 30 is greater than x | unknown | |
d19254 | test | if someone looks for this question, I have the answer:
https://gjs-docs.gnome.org/clutter7~7_api/clutter.shadereffect#method-set_uniform_value value - a GObject.Value GObject.TYPE_FLOAT for float
and in gjs GTK Javascript they have https://gjs-docs.gnome.org/clutter7~7_api/clutter.value_set_shader_float
value_set_shader_float(value,[float]) method - Value must have been initialized using %CLUTTER_TYPE_SHADER_FLOAT.
and in Javascript version of GTK they dont have any way to initialize that CLUTTER_TYPE_SHADER_FLOAT or GObject.TYPE_FLOAT
The solution is:
function make_float(val) {
return Math.floor(val)==val?val+0.000001:val;
}
A: As of GJS 1.68.0 (GNOME 40), passing a GObject.Value works:

d19256 | test | ' + data);
client.destroy();
});
client.on('close', function() {
console.log('Connection closed');
});
With the updated code, the timeout does not appear to take effect. When i start this client with no corresponding server, the result shows below with no 4 second wait.
Is the server running at 9000?
Is the server running at 9000?
Is the server running at 9000?
Is the server running at 9000?
…
Update (Barking up the wrong tree?)
I went back to look at the socket.on('error') event and saw that the close event is called immediately after the error. So the code will close out the tcpclient without waiting for 4 seconds. Any better ideas?
A: You're timeout is reversed.
Should look like:
var net = require('net');
var HOST = '127.0.0.1';
var PORT = 9000;
var client = new net.Socket();
client.connect(PORT, HOST, function(){
console.log('CONNECTED TO: ' + HOST + ':' + PORT);
client.write('I am Superman!');
});
client.on('error', function(e) {
if(e.code == 'ECONNREFUSED') {
console.log('Is the server running at ' + PORT + '?');
client.setTimeout(4000, function() {
client.connect(PORT, HOST, function(){
console.log('CONNECTED TO: ' + HOST + ':' + PORT);
client.write('I am the inner superman');
});
});
console.log('Timeout for 5 seconds before trying port:' + PORT + ' again');
}
});
client.on('data', function(data) {
console.log('DATA: ' + data);
client.destroy();
});
client.on('close', function() {
console.log('Connection closed');
});
The function you want to run after the timeout is the callback. That's the one that waits for execution.
Also, change your while to an if, that condition won't change during a single error event. And your parens and brackets are mismatched.
A: per my comment on accepted answer I discovered an issue using the .connect callback vs the 'connect' listener. Each time you call .connect it cues the callback (adds a listener) even though the connection fails. So when it finally does connect all those callbacks get called. So if you use .once('connect'.. instead that won't happen. Below are logging statements from my project's client code that led me to this observation.

d19257 | test | Convert the AGE column to float first, to avoid trying to convert string to float:
df['AGE'] = df['AGE'].str.replace('%', '', regex=True).astype(float)
I would suppose to then replace missing AGE values with -1 instead of 'N/A' to simplify binning.
df['AGE'] = df['AGE'].fillna(-1)
So, strictly speaking, it would not have been necessary here to do the conversion to float first to avoid the error message. Nevertheless this is still the sensible order of steps.
Then, define custom ranges and do the binning:
ranges = [-1, 0, 18, 30, 50, 65, 75, np.inf]
labels = ['Not_Availabe', '18 and under', '19-30', '31-50', '51-65', '66-75', '75+']
df['AGE_labeled'] = pd.cut(df['AGE'], bins=ranges, labels=labels)
# print the result
print(df['AGE_labeled'].value_counts())

INSERT INTO RegressionTable (
Ticker, TradeDate, HighPrice, LowPrice, TradePrice, TotalVolume, TotalValue

my @files = qw(red.txt green.txt blue.txt);
for my $file (@files) {
insert_file($file);
}
Or if the target table varies per file, define a hash:
my %files = (
'red.txt' => 'RedTable',
'blue.txt' => 'BlueTable'
);
while ( my ($file, $table) = each %files ) {
insert_file($file, $table);
};
Not sure how you'd use Bulk Insert given the field separator in your data file seems to be indeterminate (i.e. the regex /(.*)(..)(..)/ defines field boundaries). You may need to use the FORMATFILE option. Also, if you generate a BULK INSERT statement using DBI, be aware that the user your SQL Server runs as must be able to read your data files over the filesystem (networked, local or otherwise). | unknown | |

d19260 | test | Use glPushMatrix() to push the current matrix, do glTranslate and draw the wall, then glPopMatrix() and draw the plane. This should only translate the wall. The problem is you seem to be doing the translate in display instead of in DrawWall where it should be.
A: A few things to expand on what Jesus was saying.
When drawing the airplane you don't want to apply any transformations to it, so you need to have the identity matrix loaded:
Push the current modelview matrix
Load the identity matrix <=== this is the step you're missing
Draw the airplane
Pop the modelview matrix
When drawing the wall you want the current transformations to apply, so you do not push the current matrix or else you've wiped out all of the translations you've built up.
Remove the Push/Pop operations from DrawWall()
At some point in your initialization, before Display is called for the first time, you need to set the modelview matrix to the identity matrix. For each subsequent call to Display, -0.02 will then be added to your translation in the y-direction. | unknown | |

d19264 | test | First of all, your network might not be able to handle this no matter what you do, but I would go with UDP. You could try splitting up the images into smaller bits, and only display each image if you get all the parts before the next image has arrived.
Also, you could use RTP as others have mentioned, or try UDT. It's a fairly lightweight reliable layer on top of UDP. It should be faster than TCP.
A: You should consider using Real-time Transport Protocol (aka RTP).
The underlying IP protocol used by RTP is UDP, but it has additional layering to indicate time stamps, sequence order, etc.
RTP is the main media transfer protocol used by VoIP and video-over-IP systems. I'd be quite surprised if you can't find existing C# implementations of the protocol.
Also, if your image files are in JPEG format you should be able to produce an RTP/MJPEG stream. There are quite a few video viewers that already have native support for receiving and displaying such a stream, since some IP webcams output in that format.
A: I'd recommend using UDP if:
*
*Your application can cope with an image or small burst of images not getting through,
*You can squeeze your images into 65535 bytes.
If you're implementing a video conferencing application then it's worth noting that the majority use UDP.
Otherwise you should use TCP and implement an approach to delimit the images. One suggestoin in that regard is to take a look at the RTP protocol. It's sepcifically designed for carrying real-time data such as VoIP and Video.
Edit: I've looked around quite a few times in the past for a .Net RTP library and apart from wrappers for non .Net libraries or half completed ones I did not have much success. I just had another quick look and this may be of this one ConferenceXP looks a bit more promising.
A: The other answers cover good options re: UDP or a 'real' protocol like RTP.
However, if you want to stick with TCP, just build yourself a simple 'message' structure to cover your needs. The simplest? length-prefixed. First, send the length of the image as 4 bytes, then send the image itself. Easy enough to write the client and server for.
A: If the latest is more important than every picture, UDP should be your first choice.
But if you're dealing with frames lager than 64K your have to-do some form of re-framing your self. Don't be concerned with fragmented frames, as you'll have to deal with it or the lower layer will. And you only want completed pictures.
What you will want is some form of encapsulation with timestamps/sequences. | unknown | |
d19265 | test | The question you want answered
When you use variable interpolation, that value to interpolate is going to resolve before the original string.
In this case, your Array.each is doing it's thing and printing out "1" then "2" and finally "3". It returns the original Array of [1, 2, 3]
output> 123 # note new line because we used print
Now that your interpolation is resolved, the rest of the puts finishes up and uses the returned value of [1, 2, 3] and prints:
output> The numbers you entered in the array were: [1, 2, 3]\n
To get the final output of:
output> 123The numbers you entered in the array were: [1, 2, 3]\n
The question everyone WANTS to answer :)
http://www.ruby-doc.org/core-2.1.4/Array.html#method-i-each
When calling Array.each with a block, the return is self.
This is "bad" in your case, because you don't want self returned. It will always return the same thing, your original array.
puts "The numbers you entered in the array were: #{array.each{|num| num*2}}"
The numbers you entered in the array were: [1, 2, 3] # WAT?
As a Sergio Tulentsev said, use .map and .join
puts "The numbers you entered in the array were: #{array.map{|num| num*2}.join(' ')}"
The numbers you entered in the array were: 2 4 6 | unknown | |
d19266 | test | In your password! method, you need to specify that you want to access the instance variable password_digest. Change to:
def password!
self.password_digest = Digest::SHA1.hexdigest(password)
end | unknown | |
d19267 | test | Ok the answer is simple. This is not XmlAttribute ... this is XmlElement.
Change attribute to:
[XmlElement("startDate")]
public DateTime StartDate { get; set; }
Are you sure element "weeks" works properly and is marked with XmlAttribute ? | unknown | |
d19268 | test | For that i simply use my own path and the name of the file.
fis = new FileInputStream(dirList[i])
ZipEntry anEntry = new ZipEntry(rootName + "/" + dirList[i].name)
zos.putNextEntry(anEntry)
with rootName = "" if your zip file does not contain any folder.
Basically your path must be relative to the root of your zip file.
I hope you understand what i mean.
A: String name = new File(filesToZipP[i]).getName();
out.putNextEntry(new ZipEntry(name)); | unknown | |
d19269 | test | The Input text contains '\n' and that means that the string is not an alphanumeric string. When I read I push the enter button and that means one more character in the string. | unknown | |
d19270 | test | You need to use UINavigationController's delegate:
@property(nonatomic, assign) id<UINavigationControllerDelegate> delegate;
Set it to an object of a class that conforms to this protocol, which implements this method:
- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated;
In this method you'll know when you have finished showing a view controller, thus if it was animated the animation has ended. Notice that if you push multiple view controllers you have to keep track of them.
Documentation:
UINavigationController
UINavigationControllerDelegate | unknown | |
d19271 | test | Asynchronously, by default. If you need them to be one-after-the-other, you can do a few things:
*
*Place the second in the callback of the first.
*Set $.ajax({async:false})
*You could possibly even set these up in a queue.
The cleanest way is probably option 2.
A: Yes, the full call for load is:
load( url, [data], [callback] )
the third optional parameter is a callback method that will be called when the asynchronous load method completes. | unknown | |
d19272 | test | First, I will challenge your belief that you actually need to do that.
with open("babar.txt", 'rb') as file:
text = file.read()
print(text[42])
then, what is the actual way to accomplish this:
with open("babar.txt", 'rb') as file:
file.seek(42)
print(file.read(1))
The first loads everything in RAM, and (if your file fits on RAM) it is incredibly fast. The second way is incredibly slow.
To go back one byte, you can do this:
with open("babar.txt", 'rb') as file:
file.seek(42)
print(file.read(1))
file.seek(-1, 1) # goes back by one relative to current position
print(file.read(1)) # reeds the same char
file.seek(-1, 2) # goes at the end of the file
print(file.read(1)) # reads the last char
Check the whence argument of seek().
Generally, one can assume making a RAM access is 1000x faster than making a HDD access, so this is probably 1000x slower than the first option.
A: i just found a solution using file.seek(file.tell()-1) so it goes back if i need it to go thank you all for your help and time. | unknown | |
d19273 | test | A little feedback about my issue, I was looking at wrong place and should have open my eyes wider. I had a non relative link for an external font :

d19274 | test | The Nexus 7 has a screen resolution of 1280X800 (source). It is somewhat surprising then that the meta tag is changing, but not surprising that your website stays the same.
EDIT:
Ok, so it's not the width then. You might try reading this article from MDN and make sure that the meta viewport can do what you are expecting. It is not quite clear what you want it to do, but the meta viewport tag does not make drastic changes, so you might just be missing it. | unknown | |

d19277 | test | try document.select("tr.AccentDark td.tableheader") | unknown | |
d19278 | test | It is possible. List of mobile user-agents.
But instead of iterating over requests.get() result, you need to pass it to BeautifulSoup object, and then select a certain element (container with data) and iterate over it.
# container with mobile layout data

Alternatively, you can achieve the same thing by using Google Organic Results API from SerpApi. It's a paid API with a free plan. Check out the playground.
The difference in your case is that you don't have to figure out things (well, you have to, but it's a much more straightforward process), don't have to maintain the parser over time, and iterate over structured JSON instead.
Code to integrate:

d19285 | test | It would be useful to have some versioning system (git, mercurial, svn...). Can you mount the network drive in Windows? (see here ). This would at least allow you to easily create project from existing sources (although working via network could be quite slow)
One hacky way I can think of is to:
*
*mount the network drive as described above and map it to some letter, say Z
*install local FTP server (e.g. FileZilla)
*configure FileZilla FTP server to use the network drive as "ftp home" (aka the folder which FileZilla will use for saving files sent over FTP) - simply use Z:\ path to point to the mounted network drive mapped to letter Z
*in NetBeans, create a new PHP project from remote server (where remote server is actually your local FileZilla server)
In theory, this should work.
A: Here is the fragment from NetBeans site:
To set up a NetBeans project for an existing web application:
Choose File > New Project (Ctrl-Shift-N on Windows/Cmd-Shift-N on OS X).
Choose Java Web > Web Application with Existing Sources. Click Next.
In the Name and Location page of the wizard, follow these steps:
In the Location field, enter the folder that contains the web application's source root folders and web page folders.
Type a project name.
(Optional) Change the location of the project folder.
(Optional) Select the Use Dedicated Folder for Storing Libraries checkbox and specify the location for the libraries folder. See Sharing Project Libraries in NetBeans IDE for more information on this option.
(Optional) Select the Set as Main Project checkbox. When you select this option, keyboard shortcuts for commands such as Clean and Build Main Project (Shift-F11) apply to this project.
Click Next to advance to the Server and Settings page of the wizard.
(Optional) Add the project to an existing enterprise application.
Select a server to which to deploy. If the server that you want does not appear, click Add to register the server in the IDE.
Set the source level to the Java version on which you want the application to run.
(Optional) Adjust the context path. By default, the context path is based on the project name.
Click Next to advance to the Existing Sources and Libraries page of the wizard.
Verify all of the fields on the page, such as the values for the Web Pages Folder and Source Package Folders.

d19289 | test | You should not need to refresh the page in order to save information into the PHP Session object. PHP Session information is stored on the server, so you can do an asynchronous HTTP request to the backend, and store information the PHP Session. I would suggest using the jQuery.ajax function (http://api.jquery.com/jQuery.ajax/) to do your async HTTP requests. If you are not familiar with jQuery, I highly suggest you get familiar with it. I also suggest you look into how AJAX works.
Also, if you are using the PHP session, if you are not using some kind of framework which does session management, you must make sure to call session_start() before using the $_SESSION variable. | unknown | |

From the doc:
The format specifier is the same as supported by date, except when the
filtered data is of type DateInterval, when the format must conform to
DateInterval::format instead.
And also about string format:
The date filter accepts strings (it must be in a format supported by
the strtotime function), DateTime instances, or DateInterval
instances. For instance, to display the current date, filter the word
"now":
Try this in this twigfiddle
A: If you use /'s as delimiter the expected format is m/d/Y,
