Hii guys. I want to edit my pdf online. How and with what resources can I make a web application that allows me to edit my pdf online like add signature and do ticks and all that stuff for free.

Hi guys, I've been looking into creating desktop GUI applications and I was fiddling around with Qt but I've given up using it as I've tried for a good few days to get it to build statically as I don't want to have to deploy it with all the DLLs, so are there any other options that allow me to create sleek and modern looking desktop GUI with c++?

Thanks in advance.

Why is there a difference between "delete" and "delete []" if C++ only interprets the start of an array as an address?

Posted: 23 Apr 2021 06:45 PM PDT

For example, wouldn't using "delete" on the address of a dynamic array of size 1 be interpreted the same as using "delete" on an address stored in a pointer? Essentially, as I see it, the same operation is happening: memory is freed at that address, and C++ doesn't "know" whether or not that is the start of an array or not, just that it is a place in memory.

Why would I use X language over Y language?

Posted: 23 Apr 2021 08:17 AM PDT

Hello y'all! I am starting a new project, and I was wondering what language I should use. I am relatively new to "complex" programming (classes and threading is where I am now as far as learning). I taught myself c++ 4 ish years ago, but just the basics (up until classes, didn't do anything c++ specific like memory management). Just finished an AP python course for school (but because it was online it wasn't officially AP), and I take Java classes outside of school (at lambas and bytes).

I am unsure which language to use and why I would use it. I am pretty good at learning things, and transferring knowledge (can rewrite things I wrote in python in c++ and vise versa easily) and I learn things fast (bad at memorizing great at improvising and understand concepts). I am willing to learn other languages for this (it's a game), looking especially at Rust and Go (in addition to c++ and python).

So, why would I use Rust or Go over c++ or python (in general)? Looking to pick a language to really learn and focus on (I bounce around too much, learning just the basics from a lot of random languages like javascript, c#, node.js, etc).

I have heard Rust called the "modern c++" because it supports things like memory management (and pointers?) but Rust helps with the more tedious parts, at the cost of "being limited" because it "accepts less" (not sure that that means, explanation would be nice).

What is Go for? I know google made it, as a more readable and reasonable c++, (more python esq look), while still being compiled.

I am open to other languages to learn, but preferably they are like c++ as far as use cases (compiled, 'fast', I will be mostly making games).

I know Python is used for a lot of 'big data's stuff, but what else is it used for? I have used it for scripts (part of my xmobar used python scripts for a while), but I have heard it's bad for games (no built in threading, and not compiled)

I am specifically making a game like Pacman, but without walls, and just 1 coin that moves when you get it. (Terminal output, with a nested for loop to draw the X and the Y). Which language should I use and WHY? (Really looking for the WHY, or type/style of language)

Thanks in advance!

Why can't I resize my image bigger than my canvas in photoshop using javascript?

Posted: 23 Apr 2021 07:47 PM PDT

my code

// get a reference to the current (active) document and store it in a variable named "doc" var doc = app.activeDocument; var layer = doc.activeLayer; layer.translate(new UnitValue(0-layer.bounds[0].as('px'),'px'), new UnitValue(0-layer.bounds[1].as('px'),'px')); // do the resizing. if height > width, resize based on width. otherwise, resize based on height if (layer.height > layer.width) { layer.resize(1280/layer.width*100,1280/layer.width*100,AnchorPosition.TOPLEFT); } else { layer.resize((doc.height.value/(layer.bounds[3]-layer.bounds[1]))*100,(doc.height.value/(layer.bounds[3]-layer.bounds[1]))*100,AnchorPosition.TOPLEFT); }

canvas size is 1280 x 720 px

How to write a photoshop script to resize the image until it covers the whole canvas? (not just fit the height)

How to make it maintain proportion and resize the shorter length to fit the canvas so that some parts can be hidden(fill the canvas)?

I'm interested on a little project that will launch google assistant on my desktop when I say "Ok Google" or "Hey Google"

I'm going to make it when it hears that, it will stimulate the keys Win+Shift+A, which will then launch google assistant.

The part I'm having trouble with is the Speech to Text aspect, I watched a video from Google that uses their Cloud API but that stuff makes no sense to me.

Can anyone refer me to a script or extremely straightforward tutorials as to how I can do this?

Btw Software is a visual studio and the language can either be C# or Python

Not Sure If I'm Using Setter Properly

Posted: 23 Apr 2021 10:43 PM PDT

I'm trying to do a self made practice problem in Java. It's a GPA Calculator and I'm attempting to use a GPA class array as well as a whole bunch of methods to populate the array.

My first two methods work fine, I think. They are meant to allocate memory for the array and read/store the class names. Here those are below.

public static void createArray(GPA_1[] studentGPA) {

 `for (int i =0; i<studentGPA.length; i++) {` `studentGPA[i] = new GPA_1("", 0, 0, 0);` `}` `}` `public static void populateClassNames(GPA_1[] studentGPA) {` `Scanner userInput = new Scanner(`[`System.in`](https://System.in)`);` `System.out.println("What classes are you taking?");` `for (int i = 0; i<studentGPA.length; i++) {` `studentGPA[i].setClassName(userInput.nextLine());` `}` `userInput.close();` `}//classNames`

But when I try to do the same thing to find out how many credits each class is worth, I get this:

Exception in thread "main" java.util.NoSuchElementException

at java.base/java.util.Scanner.throwFor([Scanner.java:937](https://Scanner.java:937)) at java.base/java.util.Scanner.next([Scanner.java:1594](https://Scanner.java:1594)) at java.base/java.util.Scanner.nextInt([Scanner.java:2258](https://Scanner.java:2258)) at java.base/java.util.Scanner.nextInt([Scanner.java:2212](https://Scanner.java:2212))

This is the code for that method and the error references the 5th line down.

public static void populateCreditsWorth(GPA_1[] studentGPA) {

 `Scanner userInput = new Scanner(`[`System.in`](https://System.in)`);` `System.out.println("Credits Each Class is Worth in the order you listed them:");` `for (int i = 0; i<studentGPA.length; i++) {` `studentGPA[i].setCreditsWorth(userInput.nextInt());` `}` `userInput.close();` `}`

I'm assuming the problem is with my setters since I've never used setters before, but I'm not sure why I'm getting a problem in populateCreditsWorth and not populateClassNames. Here is my whole class for reference.

class GPA_1 {

`private String className;` `private int letterGrade;` `private int creditsWorth;` `private double gradePoints;` `public GPA_1(String className, int creditsWorth, int letterGrade, double gradePoints){` `this.className=className;` `this.letterGrade=letterGrade;` `this.creditsWorth=creditsWorth;` `this.gradePoints=gradePoints;` `}//GPA 1 constructor` `public String getClassName() {` `return className;` `}` `public int getLetterGrade() {` `return letterGrade;` `}` `public int getCreditsWorth() {` `return creditsWorth;` `}` `public double getGradePoints() {` `return gradePoints;` `}` `public void setClassName(String incomingName) {` `className = incomingName;` `}` `public void setLetterGrade(int incomingLetter) {` `letterGrade = incomingLetter;` `}` `public void setCreditsWorth(int incomingCredits) {` `creditsWorth = incomingCredits;` `}` `public void setGradePoints(double incomingGradePoints) {` `gradePoints = incomingGradePoints;` `}`

}//GPA Class

Thank you for your help and please let me know if you need to see more code! Main is pretty much just calling the methods and creating GPA_1[] studentGPA at the moment

Best way to get a unique ID

Posted: 23 Apr 2021 03:38 PM PDT

I need to repeatedly generate a unique 32-bit number. Which one of the following two methods would be better at minimizing the numbers of collisions (e.g. repeated results)?

A true random number generator spitting out 32-bit values
Start with a guaranteed unique 80-bit value and hash it down into 32-bits (hashing function TBD).

I'm assuming #1, for if my TRNG is truly random, the distribution should be uniform, right? Whereas whatever hash function I use for #2 would likely skew results one way or the other ... but I'm not completely confident in this.

Download twitter website in .html?

Posted: 23 Apr 2021 01:06 PM PDT

I want to download a twitter profile to edit in .html, but I also want it to be normally visible in chrome. But when i download it with chrome it always doesn`t look right. Pictures for example aren`t placed correctly. Any ideas, how I could download the page as an .html, so that it doesn´t change how it looks?

What should I know to create an ‘elite proxy’?

Posted: 23 Apr 2021 07:00 PM PDT

https://www.scrapehero.com/how-to-rotate-proxies-and-ip-addresses-using-python-3/#full-code:~:text=blocked.-,Elite%20Proxy

Transparent Proxy – A transparent proxy is a server that sits between your computer and the internet and redirects your requests and responses without modifying them. It sends your real IP address in the HTTP_X_FORWARDED_FOR header, this means a website that does not only determine your REMOTE_ADDR but also checks for specific proxy headers that will still know your real IP address. The HTTP_VIA header is also sent, revealing that you are using a proxy server.

Anonymous Proxy – An anonymous proxy does not send your real IP address in the HTTP_X_FORWARDED_FOR header, instead, it submits the IP address of the proxy or it'll just be blank. The HTTP_VIA header is sent with a transparent proxy, which would reveal you are using a proxy server. An anonymous proxy server does not tell websites your real IP address anymore. This can be helpful to just keep your privacy on the internet. The website can still see you are using a proxy server, but in the end, it does not really matter as long as the proxy server does not disclose your real IP address. If someone really wants to restrict page access, an anonymous proxy server will be detected and blocked.

Elite Proxy – An elite proxy only sends REMOTE_ADDR header while the other headers are empty. It will make you seem like a regular internet user who is not using a proxy at all. An elite proxy server is ideal to pass any restrictions on the internet and to protect your privacy to the fullest extent. You will seem like a regular internet user who lives in the country that your proxy server is running in.

Need a Linux mail server with API for outside use

Posted: 23 Apr 2021 07:30 AM PDT

Hello

I need a mail server that sends and receives emails, but I need to manage it completely from web.

User registrations, composing emails, checking inbox, reading emails, managing accounts, etc. are all from a website.

Here is my stack:

Linux - PostgreSQL - ASP.NET Core

So the mail server should have APIs for all of its tasks and I will call them from an ASP.NET Core app.

Which Linux mail server do you purpose?

Thanks for your help.

How do sites like picuki work?

Posted: 23 Apr 2021 04:37 AM PDT

They show Instagram content like photos and allow you to watch stories anonymously. They claim they don't host Instagram content on their servers however you can find deleted content on their sites. If you search for an user there they show you their content like images and stories. If the user delete the content on Instagram and you search on those websites again the content is still there.

Create drag-n-drop widget for script?

Posted: 23 Apr 2021 03:22 AM PDT

I have a small utility script written in Python that takes a file path as it's only argument. While I'm happy to run it from the command line, I'd like a few colleagues to be able to use it as well so I'd like to have a simple GUI (something like a 50x50px area with the text 'Drop file here') where the user can drop the file s/he wants to process and run the script on the dropped file.

What would be the easiest way to do this? One of the Python GUI frameworks? Automator/AppleScript? Something else? (I've tried using AppleScript but i can't seem to parse the file name correctly for it to work..)

Any certification test on Java coding?

I would like to know if there is any Java coding certification test available? Not Oracle, not LeetCode and not Hackerrank but something that you will get a certification when you passed all the coding questions - Java specifically.

Tks.
