• Hello and welcome back to my blog! This time I will be reviewing the work I’ve done during the first coding period of GSoC ’23. This blog is written as part of my work for GSoC ’23, to detail all the work I have done. Let’s get started!

Distributions and Operating Systems

• Sorry for the late blog post everyone! Personal life and some roadblocks on the project got in the way but I am proud to say that the driver is up and working!

• I got the semaphore problem settled, but I then ran into a problem where the data that the application on the interface side sends a packet was then not receiving the packet. Through some debugging I found out that the interface, when it goes into device_consumer_thread for getting the receive function, it fails here. Looking deeper into when that interface->receive_funcs element gets assigned I found the function here which I realized is never called when I call ifconfig to set up the interface. I ran into the solution to the problem by just changing the type of datalink frame from loopback to an ethernet frame that the interface will be using from now on. That brought the packet to an interface and I started to get a new problem of course

Fedora Family / IBM

• Available as a cloud service, Red Hat Trusted Software Supply Chain provides a DevSecOps framework to create applications more securely. Vincent Danen is the VP of Product Security at Red Hat and joins us in this episode.

• Red Hat has been a Secure Open Source software provider for very long.

• Whenever phone-based thermal cameras are brought up here on Hackaday, we inevitably receive some comments about how they’re a bad investment compared to a standalone unit. Sure they might be cheaper, but what happens in a couple years when the app stops working and the manufacturer no longer feels like keeping it updated?

• When the Antikythera Mechanism was first discovered, it wasn’t viewed as the wonder that we know it today. Originally the divers who found the device and the first scientists to look at it wrote it off as an astrolabe or other some other common type of clock. It wasn’t until decades later when another set of scientists x-rayed the device and surveyed more of the shipwreck where it was found that it began to become one of the more important archaeological discoveries in history. There have been plenty of attempts to recreate this device, and this replica recreates the mechanisms of the original but is altered so it can be built in a modern workshop.

• In the fourth chapter of the series, learn to use basic mathematics in Bash.

• The design philosophy of Unix is fairly straightforward. Software should do one thing as simply as possible, and do that one thing only. As a design principle this is sound advice even well outside of the realm of Unix, and indeed software in general, but that doesn’t stop modern software packages from being too large for their own good. So, if you’re tired of bloated chat programs like Slack or Mattermost with their millions of lines of code, you might instead favor something like Simple Unix Chat (suc).

• Red Hat fiasco continues and we have an opinion on it. Apart from that you see the continuation of our Bash Basics and Terminal Tuesday series.

• In the world of shell scripting, efficient string manipulation is a crucial skill. Being able to replace one substring with another in a given string can significantly enhance the functionality and flexibility of your bash scripts.
