I am a Ruby on Rails developer. I specialise in Point of Sale Systems. Recently, one of my customers found a way to copy my app with the DB structure and shared the app amongst his friends(theft/piracy).

How can I safeguard my app from being copied/duplicated/stollen? Can I compile my rails app so as to hide the source code?

I was also thinking about use a MAC address as one of the app sessions. This any developer can take out of the code. I thought of not installing MySQL Workbench so as to hide DB Structure, but anyone can reinstall it. What can I do secure my Rails app?

To start off: I have an app that takes a byte array and loads assembly from it.

My idea, to prevent (easy)piracy, was to have an encrypted string on server, download it on client, decrypt it to get for example: std::string decrypted = "0x4D, 0x5A, 0x90, 0x0, 0x3, 0x0, 0x0, 0x0, 0x4";

Then to convert from string to binary(byte array) so it would be

I'm not entirely sure if Stack Overflow is the correct website to ask this question, but I have been thinking about it ever since a friend mentioned it to me a week ago. I know on a baseline level what hardware acceleration does: offloads certain workloads to other components in your computer (i.e. your GPU or sound card) to improve performance in various applications. I just would like to know what exactly is happening when hardware acceleration is on v/s off when streaming a Google Chrome window and why it makes a difference in a completely different application.

If you're unfamiliar with what I'm referencing in the title, here's a simple example of what I mean: Let's say you want to watch a Netflix show or sporting event with your friends on Discord, so you all hop in a call together on the app to watch you stream the video in a Chrome tab. However, when your friends join the stream, they can hear the audio of what you're streaming but the video feed is blacked out for those watching. Interestingly enough, one of the solutions people have found to this issue is disabling hardware acceleration in Google Chrome's settings which allows the video and audio to be streamed no problem.

It makes sense why this occurs: to prevent potential piracy and illegal redistribution of copywrited material, but why does disabling hardware acceleration re-enable this functionality? Does hardware acceleration allow data to be shared between apps? Does Discord set a flag saying a particular window/screen is being streamed and Chrome can only "see" that flag while hardware acceleration is enabled?

I guess the underlying question is: how does having hardware acceleration enabled allow Netflix, a TV provider or any other website for that matter to know their content is being streamed?

feel free to recommend other tags for this post, didn't want to include discord because it's not referencing their API

My Android app provides the functionality to watch & download video lectures. I want to protect these videos from piracy/sharing. We are using Azure Media Service to store videos and I need to play these videos in Android Native player(ExoPlayer) by applying Widevide DRM encryption.

Is there a good tutorial/blog series on Azure Media service with Widevine DRM protection to play it on Android ExoPlayer?

Can someone please help/guide me as I just have started working on it?

Thanks in Advance.

I have read some question's answer on stackoverflow about how to prevent an app from being shared after downloading it form Google Play Store. Such as:

Adding Google Play Licensing: How to secure an Android app against sharing apps like ShareIT & more?

Adding Google Play Licensing and In-app Billing: How to prevent android app being downloaded outside google play

In some places, I have also seen Google Play Licensing can be cracked with some third party softwares or rooting the device. Such a video's link of youtube: How To Remove License Verification From All Android Apps

However, the video was uploaded three years ago, so I don't know if it will work in 2020 or there might be other new ways of doing it.

So, is it a better option to publish an app with in-app billing/purchase to avoid piracy or it also have some drawbacks?

I a following this course on Pluralsight:
https://app.pluralsight.com/library/courses/getting-started-android-development/table-of-contents and when I create my project with the "Basic Activity", My activity_main looks completely different than his. The first one is mine and the second one is his: He only has a constraint layout with a Text view, but I have a coordinator layout and a app bar layout and a toolbar and all this stuff which I don't know. I haven't changed mine a bit. I am not able to post anything else from the video because of piracy, but I can give you more info on my project if you want.

I am trying to make a posting system for a project I am working on. Problem is, for some reason, all $_POST values are null, even if they are supposed to be set. As a result, my PHP script does not work.

I can't tell why this is the case, as it was working fine just yesterday. How can I fix this?

I want to call "privacy policy" and "user terms" weblinks on the same WkWebView Controller. I defined two different buttons in the initial view controller and when either of them is pressed I assign the related URL string in the variable. Then I pass it to WkWebView controller via perform segue. Please see both controllers below. My problem is at first run, URL returns nil because when I press the button it jumps to WkWebView Controller and crashes. If I assign a default link at initialization it works as expected. I don't understand why it does not proceed URL assignment line at first run. Any help very much appreciated since I could not find any solution yet. (Apple links are just for example)

Initial controller to assign the URL and perform segues:

I'm working on a template (link below) using HTML/CSS but I am having a major setback in finishing my template. I am using colored borders to show how I want my template to be. Everything is working pretty well except for one major drawback:

• Template Link on CodePen
• .page-content (green dashed border) and .main-page (purple solid border) does not contain the .content div's and change height when more .content div's are added
