javascript not able to update value of input box : <p>I have some input box. Here is the HTML</p>
<pre><code><input name="dog_shipping_price" class="input" id="shipping_price_<?php echo $id; ?>" value="<?php echo $shipping_price; ?>" />
</code></pre>
<p>In some javascript i am trying to update its value</p>
<pre><code>$('.shipping_price_'+item.id).val(parseFloat(item.shipping_price));
</code></pre>
<p>i also tried </p>
<pre><code>$('.dog_shipping_price').val(parseFloat(item.shipping_price));
</code></pre>
<p>i verified that <code>item.id</code> is the right value and item.shipping_price is also there with the following:</p>
<pre><code>console.log(parseFloat(item.shipping_price));
</code></pre>
<p>when i run my code the input box value is not updated</p>

How to read from a file using Haskell? : <p>I am trying to read from a file. I want to split each line from a file into its own string. I am thinking of using the lines command in order to make a list of Strings of all the lines. I then plan to use the words command to spilt each line into a list of words. However, I am very new to functional programming/Haskell, and I don't fully understand the syntax. So, to begin, how do you read each line from a file and store it? </p>
<p>I attempted the following code, but it does not compile. </p>
<pre><code>main :: IO ()
main = do
contents <- readFile "input.txt"
contents1 = lines contents
</code></pre>

Perl Parser Error - premature end of data problems : I'm very new to both Perl and XML. So please be patient with me.
I am running into periodic problems with a Perl sub that creates an XML request file, sends it to UPS, takes the XML response file, extracts the data, then carries on with the script.
The problem I'm finding is that occasionally it seems to get hung up on the XML. Either it stops and posts the XML response file on the screen as a "software error", or it kicks an error that says `:2: parser error : Premature end of data in tag (insert bit of XML tag here)`
I'm guessing that the problem is from the XML request/response sub not finishing completely before the script tries to move on, but I'm not having any luck in figuring out how to avoid this, or stall the page load until the script is done.
I can't seem to recreate the error reliably enough either to debug. I can run it, and get an error, but then the next 20/30 loads are all fine.
Is there a way to maybe watch for something to not return right and then attempt to reload the page again, or... something. Not knowing what the problem is, i'm really stuck on not having a clue how to work around it.
I can post the sub and what not if that would help.
Thank you! | 0debug |

Weird headers c++ : <p>On <code>A.h</code> i do not have to <code>#include</code> anything or use namespace for anything. </p>
<p>On the other header, <code>B.h</code> i have to include <code>vector</code> and <code>using namespace std</code>. Both of this headers are not linked. Seems to be a file problem. When i copy the contents of <code>A.h</code> (without any problems) to <code>B.h</code>, i still get a compiler error saying <code>string</code> is not a type name and <code>vector</code> is not a template although the compiler did not state anything when the same content was on <code>A.h</code>. I am coding c++ on visual studio. What is going on?</p>

JSON Web Token expiration : <p>On most of the JWT (JSON Web Token) tutorial (e.g: <a href="https://jwt.io/introduction/" rel="noreferrer">this</a> and <a href="https://www.toptal.com/java/rest-security-with-jwt-spring-security-and-java" rel="noreferrer">this</a>) are saying, once validated you can use the incoming token to get client information without validating it from the DB.</p>
<p>My question is, how invalid user situation is maintained then? What I mean is, lets say a client just got a JWT token which expires in one week. But for very specific reason lets say we decided to invalidate the user, and don't want the user to access our API. But still that user has a token which is valid and user can access the API. </p>
<p>Of course if we take a round trip to DB for each request then we can validate if the account is valid or invalid. My question is, what is the best way to take care this kind of situation for long lived tokens.</p>
<p>Thanks in advance.</p>

How is WordPiece tokenization helpful to effectively deal with rare words problem in NLP? : <p>I have seen that NLP models such as <a href="https://github.com/google-research/bert" rel="noreferrer">BERT</a> utilize WordPiece for tokenization. In WordPiece, we split the tokens like <strong><code>playing</code></strong> to <strong><code>play</code></strong> and <strong><code>##ing</code></strong>. It is mentioned that it covers a wider spectrum of Out-Of-Vocabulary (OOV) words. Can someone please help me explain how WordPiece tokenization is actually done, and how it handles effectively helps to rare/OOV words? </p>

How to get class of an object? : <p>I need to get the exact class of an object to raise TypeError and print it on to the console.</p>
<pre><code>def diff(a,b):
retset = []
if not isinstance(a,set) or not isinstance(b,set):
raise TypeError("Unsupported operand type(s) for -: '{}' and '{}'".format(type(a),type(b)))
else:
for item in a:
if not item in b:
retset.append(item)
return set(retset)
</code></pre>
<p>if I pass args that are not sets, for example, 1 set and 1 list, this outputs
Unsupported operand type(s) for -: class 'set' and class 'list'</p>
<p>whereas I want the output as
unsupported operand type(s) for -: 'set' and 'list'</p>
<p>Is there a specific built-in functions like type()?</p>

Print a pdf without visually opening it : <p>The thing I want to build is that by clicking a button I want to trigger the print of a PDF file, but without opening it.</p>
<pre><code>+-----------+
| Print PDF |
+-----------+
^ Click *---------> printPdf(pdfUrl)
</code></pre>
<p>The way how I first tried it is to use an iframe:</p>
<pre><code>var $iframe = null;
// This is supposed to fix the onload bug on IE, but it's not fired
window.printIframeOnLoad = function() {
if (!$iframe.attr("src")) { return; }
var PDF = $iframe.get(0);
PDF.focus();
try {
// This doesn't work on IE anyways
PDF.contentWindow.print();
// I think on IE we can do something like this:
// PDF.document.execCommand("print", false, null);
} catch (e) {
// If we can't print it, we just open it in the current window
window.location = url;
}
};
function printPdf(url) {
if ($iframe) {
$iframe.remove();
}
$iframe = $('<iframe>', {
class: "hide",
id: "idPdf",
// Supposed to be a fix for IE
onload: "window.printIframeOnLoad()",
src: url
});
$("body").prepend($iframe);
}
</code></pre>
<p>This works on Safari (desktop & iOS) and Chrome (can we generalize it maybe to webkit?).</p>
<p>On Firefox, <code>PDF.contentWindow.print()</code> ends with a <code>permission denied</code> error (even the pdf is loaded from the same domain).</p>
<p>On IE (11), the <code>onload</code> handler is just not working.</p>
<hr>
<p>Now, my question is: is there another better way to print the pdf without visually opening it to the user?</p>
<p>The cross browser thing is critical here. We should support as many browsers as possible.</p>
<p>What's the best way to achieve this? Is my start a good one? How to complete it?</p>
<p><sub>We are now in 2016 and I feel like this is still a pain to implement across the browsers.</sub></p>

Google Data Studio & AWS MySQL SSL Connection : <p>I am trying to remotely connect Google Data Studio with our MySQL Database, which is hosted on an AWS instance. To allow for a secure connection, we added SSL access to the AWS's MySQL database user as recommended in the <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_MySQL.html#MySQL.Concepts.SSLSupport" rel="noreferrer">documentation</a>:</p>
<pre><code>GRANT USAGE ON *.* TO 'encrypted_user'@'%' REQUIRE SSL;
</code></pre>
<p>The problem here is that AWS, unlike <a href="https://cloud.google.com/sql/docs/mysql/configure-ssl-instance" rel="noreferrer">GOOGLE CloudSQL</a>, only generates a <strong>Server certificate</strong>, and not a <strong>Client certificate</strong>, nor a <strong>Client private key</strong> (as far as I can tell). Both the latter is needed to enable SSL for Google Data Studio & MySQL connection. </p>
<p><a href="https://i.stack.imgur.com/fWIfj.png" rel="noreferrer"><img src="https://i.stack.imgur.com/fWIfj.png" alt="enter image description here"></a></p>
<p>Just to add a side-note, we also white-listed Google's recommended IPs as listed <a href="https://support.google.com/datastudio/answer/7088031?hl=en" rel="noreferrer">here</a>. There are a lot of users in this <a href="https://www.en.advertisercommunity.com/t5/Data-Studio/Unable-to-connect-DataStudio-to-MySQL-data-on-hosting-company/m-p/1650272" rel="noreferrer">thread</a> complaining that white-listing specific IPs does not work, they had to add wildcard on the subnets. So we have also added addresses of the /16 subnets for each IP: </p>
<pre><code>64.18.%.%
64.233.%.%
66.102.%.%
66.249.%.%
72.14.%.%
74.125.%.%
108.177.%.%
173.194.%.%
207.126.%.%
209.85.%.%
216.58.%.%
216.239.%.%
</code></pre>
<p>Finally, one does not need to restart the AWS firewall after white-listing new IPs, it is immediately in-effect. </p>
<p><strong>My Questions:</strong></p>
<ul>
<li><p>Is there absolutely no way to create a client certificate and a client private key on MySQL hosted on AWS ?</p></li>
<li><p>I would really want to use SSL between Google Data Studio (GDS) and our MySQL-DB, but the GDS-UI does not allow us to connect without filling in the client certificate and client private key. Is there any work around at the moment for me to allow this secure connection ? </p></li>
</ul>
<p>Thanks in advance!</p>

I'm fairly new to Linq and EF. Having problems comparing strings in Linq entities and SQL : Any way the comparison of strings is incorrect?
I've already tried the String.Equals or CompareTo but those return boolean values, i read for Linq the comparison String == string is like a WHERE statement from SQL.
public IHttpActionResult GetMultifiberResult(string partNumber)
{
var list = db.MultifiberResults.Where(s => s.PartNumber ==
partNumber).ToList();
return Ok(list);
}
list should return a bunch of values where the column PartNumber from the DB is equal to parameter partNumber. When I search using int comparison it does find matches in an int column but not with varchar columns. Controller always returns empty and the count is 0. | 0debug |

Saving a Postman header value into a variable throughout requests in a collection : <p>Good afternoon Stackers,</p>
<p>I am trying to automate my test suite in Postman so that I don't have to manually go into each request and change that header value to what I initially put in the first request. </p>
<p>My test suite currently looks like:</p>
<p>First Request:</p>
<pre><code>var headerValue = postman.setGlobalVariable('Number', headerValue);
console.log("Number is: " + headerValue);
</code></pre>
<p>Second Request Header:</p>
<pre><code>Number - {{headerValue}}
</code></pre>
<p>I would expect headerValue to have the value of 'Number' since I have set it as a global variable but it is coming back as undefined. I'm not sure what I am doing wrong.</p>

Securing Spring Boot API with API key and secret : <p>I would like to secure the Spring Boot API so it is accessible only for the clients that has valid API key and secret. However, there is no authentication (standard login with username and password) inside the program as all data is anonymous. All I'm trying to achieve is that all API requests can be used only for specific third party front-end.</p>
<p>I found a lot of articles about how to secure the Spring Boot API with user authentication. But I don't need user authentication. What I am thinking of is just provide my client with API key and secret so he has access to the endpoints.</p>
<p>Could you please suggest me how can I achieve this? Thank you!</p>

Intellij idea auto import across files : <p>I have auto import enabled in idea, but it requires me to open the file in the editor (like it should). Now, i have done some regex magic, which means across 100+ classes i am using new classes that need to be imported. Since its all done with find/replace, those files have never been opened in the editor, and therefore the new classes havent been auto imported. Is there any way to run auto import unambiguous references across all files? cause currently, i have to compile, and then open all the files from the errors window? Optimize imports aparently doesnt do new imports.</p>

public static void main(String[] args) {
int[] array = {3,4,6,2,7,1,8,6};
mergesort(array);
}
}
My issue is that I'm getting an out of bounds exception. I'm using the debugger and have found that after mergesort(left) and mergesort(right) have finished recursively running, the arrays left and right, which go into the merge function, have the values [3] and [4] respectively, which is correct. But when the debugger jumps into the merge function, left has value [3] and right, for some reason is length 2 and has the value [3,4]. This is the source of my out of bounds exception, though I'm not sure why when the merge function runs for its first time, it changes the value of "right".

Is there a DynamoDB max partition size of 10GB for a single partition key value? : <p>I've read lots of DynamoDB docs on designing partition keys and sort keys, but I think I must be missing something fundamental.</p>
<p>If you have a bad partition key design, what happens when the data for a SINGLE partition key value exceeds 10GB?</p>
<p>The 'Understand Partition Behaviour' section states:</p>
<p>"A single partition can hold approximately 10 GB of data"</p>
<p>How can it partition a single partition key?</p>
<p><a href="http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GuidelinesForTables.html#GuidelinesForTables.Partitions" rel="noreferrer">http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GuidelinesForTables.html#GuidelinesForTables.Partitions</a></p>
<p>The docs also talk about limits with a local secondary index being limited to 10GB of data after which you start getting errors.</p>
<p>"The maximum size of any item collection is 10 GB. This limit does not apply to tables without local secondary indexes; only tables that have one or more local secondary indexes are affected."</p>
<p><a href="http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/LSI.html#LSI.ItemCollections" rel="noreferrer">http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/LSI.html#LSI.ItemCollections</a></p>
<p>That I can understand. So does it have some other magic for partitioning the data for a single partition key if it exceeds 10GB. Or does it just keep growing that partition? And what are the implications of that for your key design?</p>
<p>The background to the question is that I've seen lots of examples of using something like a TenantId as a partition key in a multi-tentant environment. But that seems limiting if a specific TenantId could have more than 10 GB of data.</p>
<p>I must be missing something?</p>

How to cast System.Windows.Forms.RichTextBox.Text as String C#? : I have this `RichTextBox rtEvents` from click-drag in form designer and I want to cast the `rtEvents` value into string.
[This solution doesn't works ][1], because I am not using `System.Windows.Controls.RichTextBox`
I am using C# VS2013, I don't want to use `.Windows.Controls.*` because its difficult for me to design the form without click-drag.
Is there any other way or workaround for it?

How to tell cmake to compile .cu files with NVCC C++ instead of NVCC C? : I have 2 files that form a small CUDA library from my previous program (which works well, btw) written on C++.
The header for this library is:
#ifndef __cudaLU__
#define __cudaLU__
#include <assert.h>
#include <cuda_runtime.h>
#include <cusolverDn.h>
#include <cusolverSp.h>
#include <cusparse.h>
#include <cuComplex.h>
#include <stdlib.h>
void denseLS(int dim,
std::complex<float> * A,
std::complex<float> * b );
void sparseLS(int dim,
std::complex<float> *csrVal,
int *csrRowPtr,
int *csrColInd,
std::complex<float> *vecVal);
#endif
And I want to use this library in my old-as-the-hills C program just by setting procedure in the head of my main.c file:
extern void denseLS(int dim, float complex *A, float complex *b);
And it fails with a bunch of similar errors. Few of them are:
..NA/cudaLS.cu(115): error: namespace "std" has no member "complex"
..NA/cudaLS.cu(115): error: expected a ")"
..NA/cudaLS.cu(137): error: identifier "csrRowPtr" is undefined
..NA/cudaLS.cu(169): error: identifier "csrColInd" is undefined
..NA/cudaLS.cu(170): error: identifier "csrVal" is undefined
..NA/cudaLS.cu(171): error: identifier "vecVal" is undefined
I tried to make a change std::complex<float> -> float complex and nothing works. Still same errors (without std error, ofc).

<p>For example, if I try to create a pod that requests 24 CPU when all of my nodes only have 4 CPUs:</p>
<pre><code>$ kubectl describe pod/large-cpu-request
Name: large-cpu-request
Namespace: default
Node: /
Labels: <none>
Annotations: <none>
Status: Pending
IP:
Controllers: <none>
Containers:
cpuhog:

Requests:

...
Events:
FirstSeen LastSeen Count From SubObjectPath Type Reason Message
--------- -------- ----- ---- ------------- -------- ------ -------
23m 30s 84 default-scheduler Warning FailedScheduling No nodes are available that match all of the following predicates:: Insufficient cpu (3).
</code></pre>
<p>At other times I have seen event messages like <code>No nodes are available that match all of the following predicates:: Insufficient cpu (2), PodToleratesNodeTaints (1)</code> when a pod's resource requests were too high, so the 3 does not seem like a constant number - nor does it seem related to my 24 CPU request either.</p>

bitcoin and blockchain dev options : <p>I don't know if this is the best place to ask this, but I'm not looking for help on a specific problem. I'm looking into block chain technology and some bit coin stuff. Ran into someone that does a lot of articles on the subject and was curious about it.</p>
<p>Since its new(ish) technology and still up and coming, I'm wonder if it would be interesting to get involved somehow and help shape and/or add to it in some way.</p>
<p>What types of development is going on out there on this technology these days. All the reading material I can find online related to development and block chain is 4+years old. I'm sure its much different today. Anyone know of some good resources for learning about the technology, what type of development opportunities there are (python preferred) and just general info?</p>
<p>thanks</p>

Heroku installs Bundler then throws error Bundler 2.0.1 : <p>I'm attempting to deploy a Rails app to Heroku. It's been a while since I deployed anything there, but I'm at a loss for what's going on here. </p>

<p>I don't understand what's going on as Heroku seems to be running through the deployment just fine, then removes bundler, then throws an error on rake tasks and asks for bundler again. I've performed <code>RAILS_ENV=production bundle exec rake assets:precompile</code> already, and it's showing up to date. I must be missing something here, hopefully someone with more recent experience in Heroku can point it out. </p>
<p><strong>Edit</strong>
I've run the <code>bundle exec rake -P</code> command as well with no failures</p>

How do I replicate Gmail's "to" field where each item is an indivisible span? : <p>I want to replicate the functionality of Gmail's "to" field where:</p>
<ul>
<li>Each address is actually a div or span containing information</li>
<li>The user treats each email address as an atomic, indivisible element -- e.g. backspace will delete it with backspace</li>
<li>Elements are added by autocomplete. The implementation of autocomplete is outside of scope of this question. It's only here to clarify that an element is not just "text".</li>
</ul>
<p>Initially, I thought it should be a contenteditable element. However, inspecting Gmail's elements more closely, it looks to me like it's an element that just responds to keydown events</p>
<p>Is there an accepted, easy way to do this, other than implementing the element (as well as key navigation) by hand?</p>
