[ Part 1 – Part 2 – Part 3 – Part 4 – Part 5 – Part 6 – Part 7 – Part 8 ]

What’s going on guys?

Welcome to part three of the Python control server series.

In part one we created our simple server and client with about 20 lines of code each (Python 3). Then in part two, we’ve added basic AES encryption to our traffic using pyAesCrypt.

Given the nature of encryption using pyAesCrypt, we we’re unable to receive any data on the server over 1024 bytes with encryption. The main reason for this is that length needs to be passed for the decryption method.

In this part we will be fixing this issue, so let’s get with it.

Traffic Encryption

What exactly is the issue we have here? Why is less than 1024 bytes ok?

Both in our server and client we are sending 1024 bytes at a time. This means that whenever we send a message containing less than 1024 bytes, we won’t run into any issues.

Now considering we have to pass a length argument for decryption, if we send a message that is 1500 bytes, the server will receive the first 1024 bytes and attempt to decrypt it – resulting in an error.

This is where we have a few different options: receive all the encrypted data and then decrypt it all at once; or, receive smaller chunks of data and decrypt on-demand. Both options have their merits, I decided this latter one would be easier to program for a encryption noob like me. 🙂

What’s going on guys?

We’re continuing with our Ionic 4 series today.

As explained in part one, we’re making a simple card matching game in order to learn the different components of the Ionic framework.

If you’re clueless about the Ionic framework, you should go check out the first part where I explain it in more detail.

I won’t ramble for too long in this post (as usual), since I explained that I’m not planning on covering code in these blog posts for Ionic – that’s what the videos are for anyway alright.

Instead, I’ll leave a summary of what goes down in this part.

Coding Summary

In this second part, we’ll get our card matching game to a playable state.

Basically, by the end of it, you’ll be able to select both cards and we’ll put conditions in place to check if the selected cards match or not.

What’s up guys? Got a sweet and short tutorial for you today!

Before we begin, I want to clarify this tutorial is for Windows 10. I’m pretty sure it should work for other Windows version as well. I will probably make a Linux version for it soon too, so watch out for it! If you’re interested in it for a different operating system, leave a comment below.

Also, if you just want the script and don’t care about the article, head all the way down to the end of the post where you will find a download for either the Python 2.7 version or Python 3 scripts. Please watch the video though, so you know the instructions to get the script working (its easy!).

Yesterday I was looking for a way to automatically change the background / wallpaper of both my monitors using a Python script (every X seconds).

Although I was able to find a few sources to change the background, it would change the background for both of my monitors at once.

I then ran into this stackoverflow post, where a user replied suggesting merging two images into one and then setting the background as a tiled image using Win32 API functions – thank you fine sir.

Well, luckily I had some previous experience with Win32 API and its functionality under Python and I also had some experience working with images in Python using Python Imaging Library (PIL).

I decided this could be a fun little challenge and set out to do it. 😉
