This week Jonathan and Rob chat with Cody Zuschlag about the Xen project! It’s the hypervisor that runs almost everywhere. Why is it showing up in IoT devices and automotive? And what’s coming next for the project? Watch to find out!

If you were asked to make an e-commerce website in 2025, what language would you reach for? Show of hands: JavaScript? Go? Pascal? Well, there was at least one taker for that last one: [jns], and he has an hour-long tutorial video showing you how he made it happen.
The site in question is the web store for his personal business, Photronic Arts, so you cannot say [jns] does not have skin in the game. From the front end, this is HTML and could be anything upto and including Shopify under the hood. It’s not, though: it’s a wholly custom backend [jns] put together in FreePascal, using the Lazarus IDE.
There’s a case to be made for Pascal in the modern day, but when we wrote that we weren’t expecting to get tips about web development. Ironically enough [jns] spends so much time giving the technical details in this video he doesn’t delve that deeply into why he chose FreePascal, especially when it’s clear he’s very familiar with C and C++. In his associated writeup on his Gopher page (link though Floodgap) [jns] simply declares it’s a language he’s quite fond of, which is reason enough of us. The source code is available, though on request, to avoid AI scraping. It’s a sad but understandable response to these modern times.
If you’re not into web development and want to see a deep-dive into how the backend works, this video is worth watching even if you don’t particularly care for Pascal. It’s also worth watching if you do know backend development, and are Pascal-curious. If neither of those things interest you, what about this Pascal Library for Arduino?
Thanks to [jns] for the tip! If you’re doing modern work with questionably-modern tools, we call that a hack and would love to hear from you.
This week Jonathan talks to Robert Wolff about DevEco! How did this developer group come to be, and what is its purpose? What are the lessons learned about building communities and working with others? Watch to find out!

Arguably, the golden age of browser gaming occurred in the 00s mostly revolving around Adobe Flash. This was an era with high creativity and a low barrier of entry, and also decentralized from gatekeeping app stores. Sadly, these times have passed us by as the security concerns around Flash led to its discontinuation and most casual gamers have migrated to the app store for their fix. But that doesn’t stop some from continuing to bring gaming to the browser, even if those games were never intended for it in the first place like this browser port of Celeste.
Celeste is an indie platformer where the player climbs a mysterious mountain while confronting her inner struggles. Originally meant for consoles and PC, a group of friends including [velzie], [bomberfish], and [Toshit] aka [r58Playz] took this as a challenge especially after seeing someone else’s half finished web port of this game. Most of the build revolves around WebAssembly (wasm) and around “cursed” .NET runtime hacks which also allow the port to run the community-made Everest mod loader. It uses a multithreaded and JIT compiling version of mono-wasm backported from .NET 10 to .NET 9 to maximize performance. The team actually first started by porting Terraria to the browser, and then moved on to this Celeste port from there.
The port of Celeste can be played here, and their port of Terraria is also available, although may not support a ton of Hackaday traffic so some patience is advised. There are also GitHub repositories for Celeste and Terraria as well. With impressive ports of relatively modern games moving into the browser, perhaps we’re entering a new golden age of browser gaming; we’ve also seen things like Minecraft implemented in only HTML and CSS lately as well.
Ok, you caught us. It certainly isn’t going to be the year of Algol. When you think of “old” programming languages, you usually think of FORTRAN and COBOL. You should also think of LISP. But only a few people will come up with Algol. While not a household name, it was highly influential, and now, GCC is on the verge of supporting it just like it supports other languages besides C and C++ these days.
Why bring an old language up to the forefront? We don’t know, but we still find it interesting. We doubt there’s a bunch of Algol code waiting to be ported, but you never know.
While some of us may have learned C in order to interact with embedded electronics or deep with computing hardware of some sort, others learn C for the challenge alone. Compared to newer languages like Python there’s a lot that C leaves up to the programmer that can be incredibly daunting. At the beginning of the year [Ethan] set out with a goal of learning C for its own sake and ended up with a working operating system from scratch programmed in not only C but Assembly as well.
[Ethan] calls his project Moderate Overdose of System Eccentricity, or MooseOS. Original programming and testing was done in QEMU on a Mac where he was able to build all of the core components of the operating system one-by-one including a kernel, a basic filesystem, and drivers for PS/2 peripherals as well as 320×200 VGA video. It also includes a dock-based GUI with design cues from operating systems like Macintosh System 1. From that GUI users can launch a few applications, from a text editor, a file explorer, or a terminal. There’s plenty of additional information about this OS on his GitHub page as well as a separate blog post.
The project didn’t stay confined to the QEMU virtual machine either. A friend of his was throwing away a 2009-era desktop which [Ethan] quickly grabbed to test his operating system on bare metal. There was just one fault that the real hardware threw that QEMU never did, but with a bit of troubleshooting it was able to run. He also notes that this was inspired by a wiki called OSDev which, although a bit dated now, is a great place to go to learn about the fundamentals of operating systems. We’d also recommend checking out this project that performs a similar task but on the RISC-V instruction set instead.
If you’re going to be a hacker, learning C is a rite of passage. If you don’t have much experience with C, or if your experience is out of date, you very well may benefit from hearing [Nic Barker] explain tips for C programming.
In his introduction he notes that C, invented in the 70s by Dennis Ritchie, is now more than 50 years old. This old language still appears in lists of the most popular languages, although admittedly not at the top!
He notes that the major versions of C, named for the year they were released, are: C89, C99, C11, and C23. His recommendation is C99 because it has some features he doesn’t want to live without, particularly scoped variables and initializing structs with named members using designated initializers. Also C89 is plagued with non-standard integer types, and this is fixed by stdint.h in C99. Other niceties of C99 include compound literals and // for single-line comments.
