Detecting matching bits in C++ : <p>I'm trying to take two <code>bitset</code> objects, for example </p>
<pre><code>a = 10010111
b = 01110010
</code></pre>
<p>and remove bits from both variables if they match in the same position/index. So we'd be left with</p>
<pre><code>a = 100xx1x1 = 10011
b = 011xx0x0 = 01100
</code></pre>
<p>Is there any way to achieve this?</p>

Encrypt data before sending to SQL by VB.NET : <p>I need to create an application where most of the data written to DB is encrypted. For that sake it shouldn't be visible/obtainable by any of the super users who can access that DB Server. Which is ok because the data is to be encrypted. The problem is that I should not have a way to see it or way to obtain it neither, however the manager user should be able to see it.</p>
<p>The application will be authenticating users using LDAP however I could grab the password when it's inputed to the form by the user and use that password as an encryption key so all data gets saved to DB encrypted and can be decrypted with that same password.</p>
<p>I have few concerns with this idea:</p>
<ol>
<li>What if the user forgets password and gets a new one by doing password reset on LDAP?</li>
<li>How can I give access to this data to manager user?</li>
</ol>
<p>I am thinking I could store the first password inputed by the user in DB encrypted with some built in function and use the encrypted string without decrypting. I could then give the manager users a way to decrypt this data using those keys but again that means I know how it works so I can take those keys from DB and decrypt if I wanted to.</p>
<p>What is the best approach here?</p>
<p>Regards

Generating heatmap layer for milions of points : <p>I'm using heatmap layer from Google Maps to display a heatmap, however, I now have too many points and it stopped working, because browser cannot handle it anymore. I've found that they provide Fusion Tables, but they're also limited: to 100k rows, which is way too low. I need to render heatmap of milions or maybe even more points. I'd be perfect if my server can have some PHP script to render a heatmap, for example, once a day. And then a client from js will just download a preloaded heatmap (on the map like google maps, but may be different map too). Is this possible with some existing technology (can be commercial)?</p>

Serving static javascript in nodejs : I'm trying to serve my bootstrap.min.js to the page. But for some reason it isn't working. But the bootstrap.min.css works perfectly fine. What did I do wrong?
[![Image of the code in Atom][1]][1]

In the picture you can see my structure and part of my code.
There isn't much going on really. I'm trying to serve the javascript like this:

<script type="text/javascript" src="../js/jquery.min.js"></script>
I do the same for the css and it works. | 0debug |
Array pointer data being cleared in between function calls without an explicit command? : <p>I have the following issue:</p>
<p>In a C++ program I have a global data structure declared as <code>Renderer Rendering_Handler</code>, which contains a member field defined as <code>vector<Render_Info> visble objects</code>.</p>
<p>What the data structures themselves are doing is not important, they are wrappers needed to abstract data to parallelize my program.</p>
<p>To be clear, Rendering_Handler is completely global, and it's in fact a singleton (I can 100% confirm that the constructor has been called once and only once for this class).</p>
<p>I have declared the following class method:</p>
<pre><code>Render_Info* Renderer::add_Render_Info()
{
visible_objects.push_back(Render_Info());
return &(visible_objects.back());
}
</code></pre>
<p>Simple enough, it creates a new <code>Render_Info</code> structure, appends it to the <code>visible_objects</code> array and returns a pointer to the object.</p>
<p>A different data structure called <code>Chunk</code> has a constructor defined as</p>
<pre><code>Chunk::Chunk(vec3 offset, World* w)
{
/*initialize some values*/
draw_info = Rendering_Handler->add_Render_Info();
draw_info->VBOs = vector<GLuint>(5);
/*initialize OpenGL VAOs, VBOs and other buffer objects*/
cout << draw_info->VBOs.size() << endl;
cout << draw_info << endl;
}
</code></pre>
<p>It also has a method defined as:</p>
<pre><code>void Chunk::update_render_info()
{
cout << draw_info->VBOs.size() << endl;
cout << draw_info << endl;
/*OpenGL stuff*/
}
</code></pre>
<p>And finally</p>
<p>We have the method that initializes everything:</p>
<pre><code>World::World()
{
/*Initialize chunks in a circular 3D array*/
loaded_chunks = new Chunk_Holder(h_radius, h_radius, v_radius, this);
for(int i=0; i<h_radius; i++)
{
for(int j=0; j<h_radius; j++)
{
for(int k=0; k<v_radius; k++)
{
(*loaded_chunks)(i,j,k)->update();
}
}
}
}
</code></pre>
<p>The output of the rpgram is:</p>
<p><a href="https://i.stack.imgur.com/NUqLm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/NUqLm.png" alt="enter image description here"></a></p>

<p><a href="https://i.stack.imgur.com/6xbPY.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6xbPY.png" alt="enter image description here"></a></p>
<p>Let's focus on the frist 2 and last 2 lines of the output, which correspond to the print statements I have added for debugging.</p>
<p>The first 2 lines indicate that 5 elements have been added to the buffer at location 0x556edb7ae200</p>
<p>The last 2 lines tell me that the same buffer (same since the memory location is the same) now contains 0 elements.</p>
<p>As you can see from the snaps of the code, no function is called in between creating the Chunks and updating them. Does anybody have an idea of what could be causing the dissapearance of these elements? </p>
<p>Have I not correctly reserved the memory? Are these objects being cleared without my knowledge due to wrong allocation?</p>

"network not manually attachable" when running one-off command against docker swarm network : <p>I'm trying to run a one-off command to initialise a database schema in a new docker swarm which is deployed with 1.13's new support for docker-compose files.</p>
<p>The swarm has the following network:</p>
<pre><code>$ docker network ls
NETWORK ID NAME DRIVER SCOPE
...
b7dptlu8zyqa vme_internal overlay swarm
...
</code></pre>
<p>defined in the <code>docker-compose.yml</code> file as:</p>
<pre><code>networks:
internal:
</code></pre>
<p>The command I run is</p>
<pre><code>docker run --rm --network vme_internal app:0.1 db upgrade
</code></pre>
<p>with the extra <code>vme_</code> prefix coming from the name that I gave the stack when deploying. Now when I run the above command, I get:</p>
<pre><code>docker: Error response from daemon: Could not attach to network vme_internal:
rpc error: code = 7 desc = network vme_internal not manually attachable.
</code></pre>
<p>How do I make the network attachable?</p>
<p>I couldn't find any specific info about attachable in <a href="https://docs.docker.com/compose/networking/%22Docker%20networking%22" rel="noreferrer">Docker networking</a> and tried adding an attribute <code>attachable</code> to the network definition without success.</p>

Python re.search Patterns : <p>I have a bunch of strings that consist of Q, D or T. Below are some examples.</p>
<pre><code> aa= "QDDDDQDTDQTD"
bb = "QDT"
cc = "TDQDQQDTQDQ"

<p>i am new to re.search, for each string, is it possible to get all patterns with any length that start with Q, and ends with D or Q, and there is no T in between the first Q and the last D or Q. </p>
<p>So for aa, it would find "QDDDDQD"</p>
<p>for bb, it would find "QD"</p>
<p>for cc, it would find "QDQQD" and "QDQ" </p>
<p>I understand the basic forms of using re.search like:</p>
<pre><code> re.search(pattern, my_string, flags=0)
</code></pre>
<p>Just having trouble how to set up the patterns mentioned above, like how to find patterns start with Q, or ends with Q, etc. Any help would be greatly appreciated!</p>

Removing spaces while printing with python : I'm printing my output in a file with a command like this
print >> outfile, columns2[0],"\t",columns2[1],"\t",columns2[2]
My problem is that I have a "space" at the end of the content of each column.
I know some times it can be solve with "sep", like this
print('foo', 'bar', sep='')
But I don't know how implement "sep" while writing in a file with my command:
print >> outfile
Any suggestion?
Thank you very much.

Spark UDF for StructType / Row : <p>I have a "StructType" column in spark Dataframe that has an array and a string as sub-fields. I'd like to modify the array and return the new column of the same type. Can I process it with UDF? Or what are the alternatives?</p>

val schema = StructType(StructField("subtable", sub_schema,true) :: Nil)

val rd = sc.parallelize(data)
val df = spark.createDataFrame(rd, schema)
df.printSchema

| |-- col1: array (nullable = true)
| | |-- element: integer (containsNull = false)

<p>It seems that I need a UDF of the type Row, something like </p>
<pre><code>val u = udf((x:Row) => x)
>> Schema for type org.apache.spark.sql.Row is not supported

<p>This makes sense, since Spark does not know the schema for the return type.

Store Data from formatted text file to Linked List c++ : I'm working on a Project @Student Course Registration System, I'm having problems Reading From a Text File and storing it in Singly Linked List, which gets updated every time a new student is added. The Data is stored in an formatted way. The Problem is my Struct has type **"char"** variables, so it gives me as Assignment Error.
Following is my code:
struct Code:
struct Student {
char stdID[10];
char stdName[30];
char stdSemester[5];
Student *next; } *Head,*Tail;
Saving Code:
// For Saving:
SFile << std->stdID << '\t' << std->stdName << '\t' << std->stdSemester << '\n';
Display Code (Reading From Text File):
// Display:
system("cls");
cout << "\n\n\n";
cout << "\t\t\t\t LIST OF COURSES" << endl;
cout << "\t\t\t ====================================================\n" << endl;
cout << "\t" << "ID" << "\t" << setw(15) << "Course Name" << "\n\n";
// Initialize:
char ID[10];
char Name[30];
char Sem[5];
ifstream SFile("StudentRecord.txt");
Student *Temp = NULL;
while(!SFile.eof()) {
// Get:
SFile.getline(ID, 10, '\t');
SFile.getline(Name, 30, '\t');
SFile.getline(Sem, 5, '\t');
Student *Std = new Student;
//node*c=new node;
// Assign:
Std->stdID = *ID;
if (Head == NULL) {
Head = Std;
}
else {
Temp = Head;
{
while ( Temp->next !=NULL ) {
Temp=Temp->next;
}
Temp->next = Std;
}
}
}
SFile.close();
system("pause"); }
P.S: I'm Having Problem at Assign Comment;
Will I have to change data type and make the whole project in String? I preferred char because I was able to format the output, and in String i'm sure it reads line by line, so I wont be able stores values from single line.

why we have to use index!=1 for alphabets in java : Iam unable to get why we should use idx != -1 in a if statement
here is my friend's code
public static String encrypt(String input, int key)
{
String alphabet="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String shifted =alphabet.substring(key)+alphabet.substring(0,key);
StringBuilder encrypted=new StringBuilder(input);
for(int i=0; i<encrypted.length();i++)
{
char current=encrypted.charAt(i);
int idx=alphabet.indexOf(current);
if(idx !=-1) {
char newchar = shifted.charAt(idx);
encrypted.setCharAt(i, newchar);
}
}
return encrypted.toString();
}
please help me

Signing ElasticSearch AWS calls : <p>I'm attempting to sign all of our AWS calls to ElasticSearch however the response is always;</p>
<p><code>User: anonymous is not authorized to perform: es:ESHttpGet on resource:</code></p>
<p>I've tried multiple key pairs and IAM users.</p>
<p>The calls within our PHP are made using the official <a href="https://github.com/elastic/elasticsearch-php" rel="noreferrer">elasticsearch-php client</a> and all requests are signed using the connector found <a href="https://github.com/wizacha/AwsSignatureMiddleware" rel="noreferrer">here</a>.</p>

<pre><code>$credentials = new Credentials('<KEY>', '<SECRET>');
$signature = new SignatureV4('es', 'eu-central-1');
$middleware = new AwsSignatureMiddleware($credentials, $signature);
$defaultHandler = ESClientBuilder::defaultHandler();

send file in c# socket worck in same machine but not in different machine : i don't speak English very well so I'm sorry if my question is not clear.
My problem is that I wrote a client/server application to send file. It works if the server and client are on the same machine, but when I put the server on another machine, I get errors when the server reads the socket.
This is the code of the server:

How to automatically toggle Airplane mode on Windows : <p>On my laptop I can toggle Airplane mode manually by pressing <kbd>FN</kbd>+<kbd>F12</kbd>, I want to do the same thing automatically from VB6 project or VBA.</p>
<p>I did a lot of search and only found answers about Enable/Disable wireless adapter or using <code>Sendkeys</code> for Windows 8:</p>
<pre><code>Dim WSh As Object
Set WSh = CreateObject("Wscript.Shell")
WSh.Run "C:\WINDOWS\system32\rundll32.exe %SystemRoot%\system32\van.dll,RunVAN", , True
Sleep 200
WSh.SendKeys " "
Sleep 1000
WSh.SendKeys "{ESC}"
</code></pre>
<p>But this code is not reliable and I don't think it will work on Windows 7 or Windows 10.</p>
<p>So my question is: Is there any reliable way to automatically toggle Airplane mode on Windows.</p>

</code></pre>
<p>I am new to javascript programming, could someone explain to me why above
output is 'abc123' not '123bcd', I thought the employeeId defined inside
foo() should be global variable and overwrite the outside one, am I wrong?</p>

Equivalent of C++ for loop in python : What will be the python equivalent to this simple C++ code :
for (i = 0; i < 10; i++)
{
for (j = 10; j > i; j--)
{
a[i]*a[j];
}
}
Especially I am having problem in the implementation of the second loop with 'j' using the
j > i

Angular validation with Required not working : <p>Simplest example ever not working.
I generated an Angular 4 application using the Angular CLI v1.0.6, changed the content of app.component.html to:</p>
<pre><code><form #form='ngForm' (ngSubmit)='submitForm(form.value)'>
<input type='email'
class='form-control' placeholder='E-mail' name='userEmail' ngModel required >
<button type='submit'>Submit</button>
</form>
</code></pre>
<p>And the content of app.component.ts to:</p>
<pre><code>import { Component } from '@angular/core';
import { FormsModule } from '@angular/forms';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
submitForm(data){
console.log(data);
}
}
</code></pre>
<p>I expected the submit function to not be fired in case I didn't supply an email, but it does.
What did I miss?</p>
<p>P.S.: I have looked around for examples (e.g.: <a href="https://scotch.io/tutorials/angular-2-form-validation" rel="noreferrer">https://scotch.io/tutorials/angular-2-form-validation</a>), but after many hours I am unable to find a solution, that's why I come to you. I know it is in my face, but somehow I can't see it.</p>

Can I use AND in a SWITH function in Access? : I have create this function to check holiday prices in MS Access:
Holiday Price: Switch([Holiday Type]="Single",£1000,[Holiday Type]="Couple",£2000,[Holiday Type]="Family",£4000)
This works but I'd like to add another field (Activity) from the table that checks if an activity has been booked. It this field is not empty I want it to return £1200 for Single, £2200 for Couple and £4200 for Family.
Any help would be greatly appreciated. I am fairly new to databases.

Swift 2.x to swift 3, XCode complaining error : Non-optional expression of type 'String' used in a check for optionals : Migrating from Swift 2.x to swift 3, I have the warning on my code :
let response=NSString(data:data!,encoding:
String.Encoding.utf8.rawValue)
let responseArray:Array=response!.components(separatedBy: "|VCSPACER|")
if let result:String=responseArray[0]
{
if let action:String=responseArray[1]
{
if let datas:String=responseArray[2]
{
.......
}
}
}
The compiler is warning at line :
"if let action:String=responseArray[0]" and line "if let action:String=responseArray[1]" and "line if let datas:String=responseArray[2]"
with the message "Non-optional expression of type 'String' used in a check for optionals"
It was perfectly working on swift 2.X but not on swift 3 . What can change on this code to make it work ?
Thanks a lot. | 0debug |
Is there a way to confirm a package-lock.json actually resolves all dependencies in a package.json? : <p>We want to add an automated check to our CI server that would prevent code from getting committed that updates a dependency in <code>package.json</code> but does not update the resolved dependency in <code>package-lock.json</code>.</p>
<p>This could happen if, for example, someone updated a dependency in <code>package.json</code> manually but ran <code>npm install</code> instead of <code>npm update</code> (<code>npm install</code> favors <code>package-lock.json</code>, if present). Or it could happen even if someone runs the correct <code>npm</code> command when updating a dependency but then forgets to commit the resulting changes to <code>package-lock.json</code>. We try to watch for these things in code review, but an automated check would definitely be better. Is there any <code>npm</code> command that does this?</p>
<p>Here's an example to illustrate.</p>
<p><strong>Before</strong>:</p>
<pre><code>// package.json
{
"lodash": "~3.1.0"
}
// package-lock.json
{
"dependencies": {
"lodash": {
"version": "3.1.3"
}
}
}
</code></pre>
<p>Someone updates <code>package.json</code> but forgets to commit the change to <code>package-lock.json</code>.</p>
<p><strong>After:</strong></p>
<pre><code>// package.json
{
"lodash": "~3.2.0"
}
// package-lock.json (not changed)
{
"dependencies": {
"lodash": {
"version": "3.1.3"
}
}
}
</code></pre>
<p>Now <code>package-lock.json</code> no longer reflects a valid set of dependency resolutions for the <code>package.json</code> file.</p>

Changing method return from void to int still pass by value? : <p>I have referred to the various explanations around here on SO about pass by value and pass by reference in Java. So far the notion is that incase of primitive datatypes it goes pass by value and incase of reference and user defined datatypes it is pass by reference. I also read that arrays are always pass by reference. However, when I try to execute the following program why the outputs are different in both these methods? The location of the object is called the reference. So if I am passing by value to <code>demoByValue_</code> it should return <code>90</code> or <code>91</code>? What am I missing here? Also, will it help to start fiddling with first pointers from C/C++ in order to get an abstract picture of this idea or what could be a real life analogy to grasp thi concept for a beginner? I did look into the analogy of house addresses and if the person wants to go to a specific house it needs the address etc. But, I want to know here that why I am failing to understand this concept? How to access the reference to the value of a primitve data type to see whats going on?</p>
<pre><code>public class Misc {
public static void main(String[] args) {
int a = 91;
System.out.println(a); //prints 91
demoByValue(a);
System.out.println(a); //prints 91
a = demoByValue_(a);
System.out.println(a); //prints 90 -- Why??
}
public static void demoByValue(int a){
a = 90;
}
public static int demoByValue_(int a){
a = 90;
return a;
}

Accessing array index greater than the array size : <p>I always thought if I accessed an array index greater than the array size that it would cause a runtime error? But it seems to be happy to run and output zero. Is this compiler specific or OS specific? Will some different environments cause a runtime error when you access an array index greater than the array size?</p>
<p>For eg;</p>
<pre><code>int foo[5];
cout << foo[5] << endl;
vector<int> bar(5);

i want to show this progress bar in ony th first time the user moves to the activity 2, every time the app launches (meaning if the app was closed and reopened and the user switched to activity 2 i want to show this progress bar again, how can i achieve this?
