[13:41] schestowitz[TR2][13:41] schestowitz[TR2]Linux kernel has an integrated firewall named netfilter, but you manipulate it through command lines such as the good old iptables, or nftables which will eventually superseed iptables.
[13:41] schestowitz[TR2]Today, I'll share my experience in using nftables to manage my Linux home router, and my workstation.
[13:41] schestowitz[TR2]I won't explain much in this blog post because I just want to introduce nftables and show what it looks like, and how to get started.
[13:41] schestowitz[TR2]I added comments in my configuration files, I hope it's enough to get a grasp and make you curious to learn about nftables if you use Linux.

[13:55] schestowitz[TR2][13:55] schestowitz[TR2]A desktop is a great introduction if youve never used BSD before. It teaches you about package management, how the base system is structured, building your first OpenZFS pool, how to perform updates, and in the case of FreeBSD, how to run tools like jails for process isolation, and bhyve for virtual machines. Its these use cases that happen to make the FreeBSD desktop extremely compe [13:55] schestowitz[TR2] lling for me. While understood to be server technologies, they also make upgrading foolproof, and the testing new software and architectures a cinch.

[13:56] schestowitz[TR2][13:56] schestowitz[TR2]Designers, makers, engineers, and hobbyists now have a new tool they can use to tackle 2D computer-aided design (CAD) projects on Linux.
[13:56] schestowitz[TR2]Design is a 2D CAD app for Linux created by developer Daniel Wood. The app has a noble aim: provide a first-class, native CAD software experience on Linux as free, open source software. It already has a small but functional feature set that makes a promising first impression.

[14:07] schestowitz[TR2]I didnt. But then I watched A Hipster History of CORS and the speaker, Devdatta Akhawe, references the history of the feature as outlined in the book JavaScript: The Definitive Guide.

[14:18] schestowitz[TR2][14:18] schestowitz[TR2]The breakout board for the Librem 5 is a great way for hardware hackers to add functionality to your phone. When attached, youll have nicely exposed programmable pins. This allows you to use I2C, serial, and many digital sensors, much like you would on a single-board microcomputer.
[14:18] schestowitz[TR2]With this setup, you can add ambient temperature, gas, humidity, and many other sensor types to your Librem 5.
Once you get your Breakout board and other needed electronics for your project, you can plan out which pins youll need. For this example, we are using I2C for an ENS160 gas sensor. Because the I2C logic voltage on the Librem 5 is 1.8V, we need to use a level translator to translate it to 3.3 [14:18] schestowitz[TR2] V.Now that we know what will be hooked up, we can short these pads with solder on the breakout board to expose 3.3V and 1.8V. With that done, we can attach the breakout board to the Librem 5.
