[MacFUSE](https://osxfuse.github.io) allows you to extend macOS's native file handling capabilities via third-party file systems.
### Features
As a user, installing the macFUSE software package will let you use any third-party FUSE file system. Legacy MacFUSE file systems are supported through the optional MacFUSE compatibility layer.
As a developer, you can use the FUSE SDK to write numerous types of new file systems as regular user space programs. The content of these file systems can come from anywhere: from the local disk, from across the network, from memory, or any other combination of sources. Writing a file system using FUSE is orders of magnitude easier and quicker than the traditional approach of writing in-kernel file systems. Since FUSE file systems are regular applications (as opposed to kernel extensions), you have just as much flexibility and choice in programming tools, debuggers, and libraries as you have if you were developing standard macOS applications.
### How It Works
In more technical terms, FUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on macOS. It provides multiple APIs, one of which is a superset of the [FUSE API](http://fuse.sourceforge.net/) (file system in user space) that originated on Linux. Therefore, many existing FUSE file systems become readily usable on macOS.
The macFUSE software consists of a kernel extension and various user space libraries and tools. It comes with C-based and Objective-C-based SDKs. If you prefer another language (say, Python or Java), you should be able to create file systems in those languages after you install the relevant language bindings yourself.
The [filesystems](https://github.com/osxfuse/filesystems) repository contains source code for several exciting and useful file systems for you to browse, compile, and build upon, such as sshfs, procfs, AccessibilityFS, GrabFS, LoopbackFS, SpotlightFS, and YouTubeFS.
File system integration made easy.

- Creates a **virtual encrypted disk** within a file and mounts it as a real disk.
- Encrypts an **entire partition or storage device** such as USB flash drive or hard drive.
- Encrypts a **partition or drive where Windows is installed** ([pre-boot authentication](https://veracrypt.fr/en/System%20Encryption.html)).

[Specs & Pricing page. ](https://store-usa.arduino.cc/products/uno-r4-wifi?selectedStore=us)
Ideally this would be good to optimize for the typewriter project getting rid of the need to use a pi entirely! Potentially..
It is also [Arduino Cloud IoT ](https://cloud.arduino.cc)Compatible as well!

### Experiments in PID control with an Arduino UNO R4 Minima-powered robot
[via arduino blog](https://blog.arduino.cc/2023/08/09/experiments-in-pid-control-with-an-arduino-uno-r4-minima-powered-robot/)
ARDUINO TEAM — August 9th, 2023
![](https://blog.arduino.cc/wp-content/uploads/2023/08/PID-Control-1024x653.jpg)
In robotics and several other disciplines, PID (proportional-integral-derivative) control is a way for systems with closed-loop feedback to adjust themselves according to sensor data without overshooting the target. Drones, for example, use PID control to remain stable without wild oscillations caused by over-correction. But implementing PID control can feel overwhelming, so Adam Soileau from element14 Presents built a simple robot for some experimentation.
This robot’s only job is to drive forward until it sees a wall, then stop at a specific distance from that wall. That isn’t hard to achieve when a robot is moving at slow pace, because the code can tell the robot to stop moving the moment it reaches the target distance. But when moving fast, the robot has to take braking acceleration into account and that is much harder to predict. PID control is perfect for this situation, because it adjusts motor output in real-time according to the incoming sensor data.

This is one of the first classes that engineers often had to take (if they were not computer science & didn't get stuck in a functional programming language class like I did) during their freshman year to learn about programming languages. Arduinos are a great introduction into programming because people get to directly see the effects of their program written in MATLAB or something directly onto the Arduino which is a little microcontroller breadboard circuit which connects to code written from your machine to operate.
I never took that Arduino course though so instead I will have to learn it from scratch from building blocks. Either way there are things I have learned along the way but it's back to basics for me.
