How to handle Web Workers "standard" syntax with webpack? : <p>I wonder if it's actually possible to handle Web Worker "standard syntax" in webpack (e.g <code>var worker = new Worker('my-worker-file.js');</code>) and how? </p>
<p>I know about <a href="https://github.com/webpack/worker-loader">worker-loader</a> but as far as I understand it needs a specific syntax and is not compatible with the standard one.</p>
<p>In other words, is it possible to bundle that file with webpack without changing the code? -> <a href="https://github.com/mdn/simple-web-worker/blob/gh-pages/main.js#L8">https://github.com/mdn/simple-web-worker/blob/gh-pages/main.js#L8</a></p>
<p>With <a href="http://browserify.org/">browserify</a>, I would use <a href="https://www.npmjs.com/package/workerify">workerify</a> transform, but I can't find anything in webpack's world.</p>

Get path to ActiveStorage file on disk : <p>I need to get the path to the file on disk which is using <code>ActiveStorage</code>. The file is stored locally.</p>
<p>When I was using paperclip, I used the <code>path</code> method on the attachment which returned the full path.</p>
<p>Example:</p>
<pre><code>user.avatar.path
</code></pre>
<p>While looking at the <a href="http://edgeguides.rubyonrails.org/active_storage_overview.html#linking-to-files" rel="noreferrer"> Active Storage Docs</a>, it looked like <code>rails_blob_path</code> would do the trick. After looking at what it returned though, it does not provide the path to the document. Thus, it returns this error:</p>
<blockquote>
<p>No such file or directory @ rb_sysopen - </p>
</blockquote>
<p><strong>Background</strong></p>
<p>I need the path to the document because I am using the <a href="https://rubygems.org/gems/combine_pdf" rel="noreferrer">combine_pdf</a> gem in order to combine multiple pdfs into a single pdf. </p>
<p>For the paperclip implementation, I iterated through the full_paths of the selected pdf attachments and <code>load</code> them into the combined pdf:</p>
<pre><code>attachment_paths.each {|att_path| report << CombinePDF.load(att_path)}
</code></pre>

When to use GO sync.Mutex with net/http and gorilla/mux? : As far as I know, the "net/http" package uses goroutines for the handlers. Is it necessary that I lock even a map with sync.Mutex in order to prevent possible bugs in the "nextId" function cause the function could count an old state of the map?
Here is my example code:
package main
import (
"net/http"
"github.com/gorilla/mux"
"io/ioutil"
"fmt"
)
var testData = map[int]string {
1: "foo",
2: "bar",
}
func main() {
r := mux.NewRouter()
r.HandleFunc("/data", getData).Methods("GET")
r.HandleFunc("/data", addData).Methods("POST")
http.ListenAndServe(":3000", r)
}
func getData(writer http.ResponseWriter, request *http.Request) {
for k, v := range testData {
fmt.Fprintf(writer, "Key: %d\tValue: %v\n", k, v)
}
}
func addData(writer http.ResponseWriter, request *http.Request) {
if data, err := ioutil.ReadAll(request.Body); err == nil {
if len(data) == 0 {
writer.WriteHeader(http.StatusBadRequest)
return
}
id := nextId()
testData[id] = string(data)
url := request.URL.String()
writer.Header().Set("Location", fmt.Sprintf("%s", url))
writer.WriteHeader(http.StatusCreated)
} else {
writer.WriteHeader(http.StatusBadRequest)
}
}
func nextId() int {
id := 1
for k, _ := range testData {
if k >= id {
id = k + 1;
}
}
return id

Python: Importing csv with comma delimiter not working for me : I am having trouble importing a csv into python. I am importing a single column list of baseball player stats separated by commas and was trying to import it into python using `pd.read_csv` and setting the `delimiter=','`. But it did not work.
I also tried to find the encoding and apply that but that also failed.
Next I added `quoting=3`. This worked but then it caused the first column and all its values to have double quotes in front [(Pic of data frame)][1] and double quotes at the end of the last column and all its values.
Also I am not sure why but as you see in the pic the second column has this strange y with a colon on it. Any help with this would be appreciated. Thanks!

dog.makeNoise(); // This will be 'woof'

<p>Basically, I don't want to repeat the makeNoise() method when I create an animal. However, this will not work. (Noise is an empty string)</p>
<p>I could use a static object like </p>

First appearance of specific key in subhashes Ruby : I have a hash:
hash = {{"number" => "7", "disk" => "70"},{"number" => "12", "disk" => "150", "global" => "yes"},{"number" => "8", "disk" => "250", "global" => "yes"}}
I want to define a string containing of value of first "global" key appearance. I know how to loop over that hash but I can't figure out how to define the first appearance of that key.

Kotlin how to return a SINGLE object from a list that contains a specific id? : <p>Good day, i'm stuck figuring out how to get a single object from a list, i did google but all the topics show how to return a <code>List</code> with sorted objects or something similar.</p>
<p>I have a <code>User Class</code></p>
<pre><code>class User() {
var email: String = ""
var firstname: String = ""
var lastname: String = ""
var password: String = ""
var image: String = ""
var userId: String = ""
constructor(email:String,
firstname: String,
lastname: String,
password: String,
image: String, userId : String) : this() {
this.email = email
this.firstname = firstname
this.lastname = lastname
this.password = password
this.image = image
this.userId = userId
}
}
</code></pre>
<p>In java i would write something like</p>
<pre><code> User getUserById(String id) {
User user = null;
for(int i = 0; i < myList.size;i++;) {
if(id == myList.get(i).getUserId())
user = myList.get(i)
}
return user;
}
</code></pre>
<p>How can i achieve the same result in kotlin?</p>

how can i api control this? : **how can i API control this?**
i want use `ble`
problem is that in api lower than 21 i should use `startlescan()` and in API 21 i should use `startscan()` and its scan callback that is not for API less than 21.
how can i separate those code to have both in my app?
[this is error][1]

i want something like this:
if(api < 21) startlescan();
if(api >= 21) startscan();

Reconstructing an image after using extract_image_patches : <p>I have an autoencoder that takes an image as an input and produces a new image as an output.</p>
<p>The input image (1x1024x1024x3) is split into patches (1024x32x32x3) before being fed to the network.</p>
<p>Once I have the output, also a batch of patches size 1024x32x32x3, I want to be able to reconstruct a 1024x1024x3 image. I thought I had this sussed by simply reshaping, but here's what happened.</p>
<p>First, the image as read by Tensorflow:
<img src="https://i.imgur.com/euaZxKf.png" alt="Input image"></p>
<p>I patched the image with the following code</p>
<pre><code>patch_size = [1, 32, 32, 1]
patches = tf.extract_image_patches([image],
patch_size, patch_size, [1, 1, 1, 1], 'VALID')
patches = tf.reshape(patches, [1024, 32, 32, 3])
</code></pre>
<p>Here are a couple of patches from this image:</p>
<p><img src="https://i.imgur.com/oseI4Cv.png[/img]" alt="Patched input #168"> <img src="https://i.imgur.com/s7g3l2B.png[/img]" alt="Patched input #169"></p>
<p>But it's when I reshape this patch data back into an image that things go pear-shaped.</p>
<pre><code>reconstructed = tf.reshape(patches, [1, 1024, 1024, 3])
converted = tf.image.convert_image_dtype(reconstructed, tf.uint8)
encoded = tf.image.encode_png(converted)
</code></pre>
<p><img src="https://i.imgur.com/XI1CZwp.jpg[/img]" alt="Reconstructed output"></p>
<p>In this example, no processing has been done between patching and reconstructing. I have made a <a href="https://pastebin.com/vPyRGcQG" rel="noreferrer">version of the code</a> you can use to test this behaviour. To use it, run the following:</p>
<pre><code>echo "/path/to/test-image.png" > inputs.txt
mkdir images
python3 image_test.py inputs.txt images
</code></pre>
<p>The code will make one input image, one patch image, and one output image for each of the 1024 patches in each input image, so comment out the lines that create input and output images if you're only concerned in saving all the patches.</p>
<p>Somebody please explain what happened :(</p>

Can obfuscated code be useful sometimes? : <p>While creating a custom 3D <code>Point</code> class with single-precision coordinate values in C#, I had to write a method to calculate the distance between two points. Then I thought about the <code>A -> B</code> graph notation meaning "from A to B", and I thought about overloading the <code>></code> operator, as it has no sense thinking about a point A being "greater" than a point B (besides, the <code>-></code> operator cannot be overloaded).</p>
<p>So I created the following methods:</p>
<pre><code>/// <summary>
/// Calculates the Manhattan distance between the two points.
/// </summary>
public static float operator>(Point p1, Point p2)
{
return Math.Abs(p1.X - p2.X) +
Math.Abs(p1.Y - p2.Y) +
Math.Abs(p1.Z - p2.Z);
}
/// <summary>
/// Calculates the euclidean distance between the two points.
/// </summary>
public static double operator>=(Point p1, Point p2)
{
return Math.Sqrt(Math.Pow(p1.X - p2.X, 2) +
Math.Pow(p1.Y - p2.Y, 2) +
Math.Pow(p1.Z - p2.Z, 2));
}
</code></pre>
<p>This results in code like this:</p>
<pre><code>var manhattan = A > B;
var euclidean = A >= B;
</code></pre>
<p>The code seems to be obfuscated but once you get the grasp of it, it is quite simple to read, and shorter than using <code>A.DistanceTo(B)</code>. </p>
<p>The question is, should I completely avoid this kind of code? If so, what's the reason why? I am quite concerned with Clean Code, and I'm not sure this could be considered <em>clean</em> or not. If you think such code is sometimes allowed, could you provide examples?</p>

That's the CSS. The current background colour is green but that's the property I want to be randomly selected upon the page loading. Thanks.

Tried detecting the a self created DeadLock : I wrote the below Java code for creating the Deadlock, I passed a resource String variable to the threads and locked it using **synchronized** block and put up an infinite loop inside that so that first thread will never ever leave it, so the second thread will not be able to access it forever.
public class MainClass {
public static void main(String[] args) {
String resourcs = "testResource";
MainClass M = new MainClass();
Thread firstThread = new Thread(M.new MyThread("First",resourcs));
Thread seconThread = new Thread(M.new MyThread("Second",resourcs));
firstThread.start();
seconThread.start();
}
class MyThread implements Runnable{
String resource;
String name;
public MyThread(String name,String resource) {
this.resource = resource;
this.name = name;
}
@Override
public void run() {
synchronized (resource) {
while(true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Still working on the thread :"+name);
}
}
}
}
}
Then in the other window, I wrote the code for detecting the Deadlock like below,
import java.lang.management.ManagementFactory;
import java.lang.management.ThreadInfo;
import java.lang.management.ThreadMXBean;
public class DetectDeadLock {
public static void main(String args[]) {
ThreadMXBean bean = ManagementFactory.getThreadMXBean();
long[] threadIds = bean.findDeadlockedThreads();
if (threadIds != null) {
ThreadInfo[] infos = bean.getThreadInfo(threadIds);
for (ThreadInfo info : infos) {
StackTraceElement[] stack = info.getStackTrace();
System.out.println("here");
// Log or store stack trace information.
}
}
}
}
But the Watch Dog detected nothing.
----------
1. Have I created the dead lock correctly? (I think yes, because the console is only printing the first thread's code)
2. Do i have to wait for some time(idk how much) for the 'Watch Dog' code to detect the Deadlock?

How to remove duplicated value with specail charecter from array in php : Here i have this array

[2]=> string(60) "läs våra leveransvillkor/reservationer"

[4]=> string(59) "läs våra leveransvillkor/reservationer"
}
I have four values are the same so i want to keep only one.
I did try to use array_unique , and even i did try this
`array_map("unserialize", array_unique(array_map("serialize", $myArray)));`
But i was not succeed in removing duplicates .I guess the issue is because of the special character .
Any help would be appreciated .

How to align 2 images with OpenCV with ORB? (fail to compile) : First of all, this is my first time using C++. I'm using C++ because OpenCV is very limited in C.
OpenCV documentation isn't the most explicative I've seen.

Note: When I write C, I always try to follow the Linux Kernel Coding Style; that's the reason I avoided `typedef`s, `namespace`s, and wrote `class` and all that stuff before everything; I like to have everything be very explicit.
The first thing is that I had to remove `#include "opencv2/xfeatures2d.hpp"` because that header does not exist on my system (Debian Stretch). However, I read that header [here][2], and it doesn't seem to contain the solution to my problem.
When I compile that file, I get the following errors:
/.../img_orb.cpp: In function ‘void img_orb_align(_IplImage*, _IplImage*)’:
/.../img_orb.cpp:78:36: error: no matching function for call to ‘cv::ORB::create(int)’

Is the example I took simply broken? Does it fail because I lack one header? Does it fail because I didn't understand some C++ stuff? Else?

<p>It gives the expected output when it's not valid, like when the number is over 255, when the input contains letters of the alphabet etc.. However, let's say I input 10.111.111.111 as my IP. It prints "Valid", even though if you tried to access that IP right now you'd fail.</p>
<p>How do I check if an IP is online as opposed to whether it's numerically valid?</p>

Scipy sparse CSR matrix to TensorFlow SparseTensor - Mini-Batch gradient descent : <p>I have a Scipy sparse CSR matrix created from sparse TF-IDF feature matrix in SVM-Light format. The number of features is huge and it is sparse so I have to use a SparseTensor or else it is too slow. </p>
<p>For example, number of features is 5, and a sample file can look like this:</p>
<pre><code>0 4:1
1 1:3 3:4
0 5:1
0 2:1
</code></pre>
<p>After parsing, the training set looks like this:</p>
<pre><code>trainX = <scipy CSR matrix>
trainY = np.array( [0,1,00] )
</code></pre>
<p>I have two important questions:</p>
<p>1) How I do convert this to a SparseTensor (sp_ids, sp_weights) efficiently so that I perform fast multiplication (W.X) using lookup: <a href="https://www.tensorflow.org/versions/master/api_docs/python/nn.html#embedding_lookup_sparse" rel="noreferrer">https://www.tensorflow.org/versions/master/api_docs/python/nn.html#embedding_lookup_sparse</a></p>
<p>2) How do I randomize the dataset at each epoch and recalculate sp_ids, sp_weights to so that I can feed (feed_dict) for the mini-batch gradient descent.</p>
<p>Example code on a simple model like logistic regression will be very appreciated. The graph will be like this:</p>
<pre><code># GRAPH
mul = tf.nn.embedding_lookup_sparse(W, X_sp_ids, X_sp_weights, combiner = "sum") # W.X
z = tf.add(mul, b) # W.X + b
cost_op = tf.reduce_sum(tf.nn.sigmoid_cross_entropy_with_logits(z, y_true)) # this already has built in sigmoid apply
train_op = tf.train.GradientDescentOptimizer(0.05).minimize(cost_op) # construct optimizer
predict_op = tf.nn.sigmoid(z) # sig(W.X + b)
</code></pre>

Cant access to variable value in array : I have array of values
var info_tab = [
["Aaaa", 53.12040528310657, 23.258056640625,1,ikona3],
["Bbbb", 53.09402405506325, 18.0010986328125,2,ikona2],
];
And here I use it in function to pass value as parameters...
Problem is with this section: label: info_tab[i][1]
var markers = locations.map(function(location, i) {
return new google.maps.Marker({
position: location,
icon: ikona2,
label: info_tab[i][1]
});
});
And i got error Uncaught TypeError: Cannot read property '1' of undefined.
I i show this via window.alert(info_tab[i][1]) it shows good value...
Where is my mistake ?

Where do I find the object names of icons in the FontAwesome free packages? : <p><a href="https://fontawesome.com/" rel="noreferrer">FontAwesome</a> is a collection of libraries of icons. In their <a href="https://www.npmjs.com/package/@fortawesome/react-fontawesome" rel="noreferrer">Usage documentation</a>, they write as an example that you can use their coffee icon by importing the coffee icon's object from the free-solid-svg-icons package, like this:</p>
<pre class="lang-js prettyprint-override"><code>import ReactDOM from 'react-dom'
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome'
import { faCoffee } from '@fortawesome/free-solid-svg-icons'
const element = <FontAwesomeIcon icon={faCoffee} />
ReactDOM.render(element, document.body)
</code></pre>
<p>Looking at the <a href="https://fontawesome.com/icons/coffee?style=solid" rel="noreferrer">FontAwesome Coffee Icon documentation</a>, I can see no reference to what package the coffee icon is included in, or what its object name is. We know from the example code that its object name is <code>faCoffee</code> and that it's included in the <code>@fortawesome/free-solid-svg-icons</code> package, but what about any of the <a href="https://fontawesome.com/icons" rel="noreferrer">other 5,365 icons</a>?</p>
<p><strong>Q:</strong> How can I find what React object name a FontAwesome icon has, and what React package it's included in?</p>

Dynamic links in Facebook mobile app is not deep linked to app : <p><strong>Problem</strong> — when opening a Firebase Dynamic Link on Facebook Mobile, the Facebook Browser consumes the deep link and does not open the intended mobile app</p>
<p><strong>Question</strong> — is there a good work around in <strong>Firebase</strong> to help Facebook deliver on the promise of presenting my Dynamic Link as intended? </p>
<p>We are aware of <a href="http://applinks.org">http://applinks.org</a>, and that Facebook is a contributor. Does <strong>Firebase</strong> have a way to configure their server using the AppLinks spec, so that Facebook will pass through the Deep Link to our app instead of consuming it.</p>
<p><strong>Background</strong> — I have created a <a href="https://firebase.google.com/docs/dynamic-links/">Firebase Dynamic Link</a> for an iOS and Android app. </p>
<p>The Dynamic link delivers everything I expect, and is a fantastic experience.</p>
<ol>
<li>When opened on iOS, it navigates to the App. If not installed, goes
App Store </li>
<li>When opened on Android, it navigates to the App. If not installed, goes to Play Store</li>
<li>When opened on non-mobile, it navigates to our Website</li>
<li>On Facebook mobile, neither 1 nor 2 happens. Result is that it goes straight to the mobile web experience, thereby eliminating the promise of the Firebase Dynamic Link</li>
</ol>

Division with if condition : <p>I just start learning ruby with an online course and in my very first exercise, I can't complete the challenge. I have to create functions to sum, subtract, multiply and divide that meet the specs conditions.</p>
<p>For the division, I need to check if it will divide per 0 or not, give the result or a warning. My code is </p>
<pre><code>def divisao(primeiro_numero, segundo_numero)
if segundo_numero > 0
primeiro_numero / segundo_numero
else
puts 'Opa! Zero como divisor'
end

<p>But when I run the specs, I get the following warning</p>
<pre><code>0 examples, 0 failures, 1 error occurred outside of examples

<p>I have changed all the functions, but this one doesn't seem to work.

How can I convert string variable into byte type in python? : <p>I want to encrypt a messages which I got from user input using Cryptography:</p>
<p>I have the following simple code:</p>
<pre><code>import os
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes
from cryptography.hazmat.backends import default_backend
backend = default_backend()
messages = input("Please, insert messages to encrypt: ")
key = os.urandom(24)
print(key)
cipher = Cipher(algorithms.TripleDES(key), modes.ECB(), backend=backend)
encryptor = cipher.encryptor()
cryptogram = encryptor.update(b"a secret message") + encryptor.finalize()
print(cryptogram)
</code></pre>
<p>When I hard code the messages <kbd>"a secret message"</kbd> with <kbd>b</kbd> prefix in the code it works fine.
What I wanted to do is to use <kbd>messages</kbd>variable to get the text from user input.</p>
<pre><code>messages = input("Please, insert messages to encrypt: ")
</code></pre>
<p>I've tried several ways to covert the string type from the input to byte type and pass it to encryptor.update method but nothing works for me.</p>
<pre><code>messages = input(b"Please, insert messages to encrypt: ")
cryptogram = encryptor.update(byte, message) + encryptor.finalize()
...
</code></pre>
<p>Versions:</p>
<p>Python 3.7.0</p>
<p>Cryptography 2.4</p>
<p>Mac OS</p>

Display an integer in reversed order : <p>I have this problem in school, and I have no idea how to start.</p>
<p><strong>Here are the directions:</strong></p>
<p>Write a method with the following header to display an integer in reversed order:</p>
<p>public static int reverse (int number)</p>
<p>Example Output:</p>
<p>Enter an integer:
12345 in reversed order is 54321</p>
<p>Note:</p>
<p>You will need to... </p>
<ol>
<li>Find the length of the integer </li>
<li>Extract each digit</li>
<li>In the event that the expected outputs do not match the output tests or the code is incomplete that the program fails to run, points will be given to the sections that the codes are written properly</li>
</ol>
<p>~~~~~~~~~~~~~~~~~~~~~~~~~</p>
<p>And here is the skeleton that they give me to work with:</p>
<pre><code> import java.util.Scanner;
public class ReverseNumber {
public static int reverse (int number) {
// FIXME 1 (50 points): Complete the method to return the number in reversed order
}
public static void main (String[] args) {
// FIXME 2 (25 points): Write the statements to prompt the user enter an integer and store it in an integer variable
System.out.println("Enter an integer: ");
/*
FIXME 3 (25 points): Write the statements to call the reverse (int number) method
Print the result in the required format
*/
System.out.println("12345 in reverse order is 54321");
}
}
</code></pre>
<p>I need to know what to put in here and where to put it in order to get it to output some thing like the example. Don't change the skeleton, just add to it.</p>
