It appeared I had traded the problem of high CPU usage for a memory leak. Last night I saw: [...]
=> ↺ Thinking About Plugins In Go
Looks like the host and plugins need to have exactly the same dependencies. To be fair, the package documentation says as much, and also states that the best use of plugins is for dynamically loaded modules build from the same source. But that doesn’t help me and what I’m trying to do, which is encoding a bunch of private struct types as Protobuf messages.
=> ↺ Fast software, the best software
Building fast software is a team effort which encompasses multiple different fields. It’s not easy, but it’s what makes a great product.
=> ↺ Rolling your own fast matrix multiplication: loop order and vectorization
If you must multiply matrices, you should use dedicated libraries. However, we sometimes need to roll our own code. In C++, you can quickly write your own Matrix template:
=> ↺ Forsp: A Forth & Lisp Hybrid Lambda Calculus Language
In the world of lambda calculus programming languages there are many ways to express the terms, which is why we ended up with such an amazing range of programming languages, even if most trace their roots back to ALGOL. Of the more unique (and practical) languages, Lisp and Forth probably range near the top, but what if you were to smudge both together? That’s what [xorvoid] did and it resulted in the gracefully titled Forsp programming language. Unsurprisingly it got a very warm and enthusiastic reception over at Hacker News.

For FreeBSD packaging (writing “ports”, as it is called), I usually just build on my host system – either in the actual host, or with poudriere – and call it a day. If it compiles on amd64 then it should work everywhere, right? (After all, “all the world’s a VAX”)
No exciting software engineering here, BTW, just a “here’s how I set up some infrastructure to help me build ports locally in various environments.”

This was my first PyCon US as the Security Developer-in-Residence. I accepted the offer shortly after PyCon US 2023, where Deb Nicholson provided an exciting cliffhanger that the PSF was close to making a hiring decision for the role during the PSF update.
=> ↺ GSoC '24 Progress: Week 1 and 2
Hi! It has been over two weeks since the coding period began. In this blog post, I will provide a brief summary of my work during the first two weeks.
After spending some time reviewing the code, I decided to start by refactoring the existing code related to ASS format subtitles. This has two main goals: first, to enable Kdenlive to read as much information as possible from ASS subtitles (specifically, the features supported by libass) and load it into the memory; and second, to ensure that Kdenlive can save all this information back to the file. Since SubtitleModel already contains a significant amount of code for ASS format subtitles, my work mainly involved refining and expanding upon this existing code while maintaining compatibility.
So far, I have accomplished the following:
