I got problems installing Matlab R2022a on Arch. Running the installer throws the following error:

```
terminate called after throwing an instance of 'std::runtime_error'
  what():  Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was: 127
fish: Job 1, 'sudo ./install' terminated by signal SIGABRT (Abort)
```

I fixed it by running the following commands.

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

It appears they have copied source code to github and updated it for C++11: https://github.com/fedetft/serial-port

Introduction

The serial port protocol is one of the most long lived protocols currently in use. According to wikipedia, it has been standadized in 1969. First, a note: here we're talking about the RS232 serial protocol. This note is necessary because there are many other serial protocols, like SPI, I2C, CAN, and even USB and SATA.

Some time ago, when the Internet connections were done using a 56k modem, the serial port was the most common way of connecting a modem to a computer. Now that we have ADSL modems, the serial ports have disappeared from newer computers, but the protocol is still widely used.

In fact, most microcontrollers, even the newer ones have one or more peripherals capable of communicating using this protocol, and from the PC side, all operating system

Unity'de 3D çalışırken kafa kurcalayan konulardan biri Quaternion'ların ne işe yaradığı ve neden bazı yerlerde rotasyon değeri olarak Euler Angle değil de Quaternion kullanıldığıdır.

3 Boyutlu rotasyon belirtmek için kullanılan Euler Açısı, bir 3x3 rotasyon matrisi ile ifade edilebiliyor. Örnek:

İdeal bir sistemde her bir rotasyon matrisinin, yalnızca tek açıya isabet etmesini isteriz. Sorun şu ki bu matrisler, her zaman için tek açıya tekabül etmeyebiliyor.
