Learn how Linux/FFmpeg C partial codebase is organized to be extensible and act as if it were meant to have “polymorphism”. Specifically, we’re going to briefly explore how Linux …
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
The past few months have been quite hectic with a slew of gigantic changes requiring lengthy articles alongside them. These big features all hitting together seems to have brought up a talking point in the community would be irresponsible to ignore. Everyone wants to know when Dolphin 6.0 is coming.

A whirlwind tour of object-oriented code in F#
AWS Fargate is a serverless technology which lets you run your containers in the cloud without having to worry about the operational overhead of managing the infrastructure. In this article, we talk about what Fargate is and how it works under the hood. We also try to compare it to other AWS Services like Lambda and…
It’s really true that time flies, especially when you don’t have to think about servers: AWS Lambda just turned 5 years old and the team is always looking for new ways to help customers build and run applications in an easier way. As more mission critical applications move to serverless, customers need more control…

The PyPy team is proud to release version 7.1.0 of PyPy, which includes two different interpreters: PyPy2.7, which is an interpreter s...
People involved in the day-to-day development of a project tend to become so familiar with its rhythm and process that they internalize it and it feels like everyone must just _know_ how each stage unfolds. Of course, from the outside looking in it's not so obvious. So I thought it might be helpful t...
Removing spaces from a string is a common task in text processing. Instead of removing single character we often want to remove all the white space characters or the punctuation characters etc.
How to make an access-limiting proxy for any API
I’m a huge proponent of designing your code around the data, rather than the other way around, and I think it’s one of the reasons git has been fairly successful… I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important…
Vim 8.1 was released in May 2018. The “main new feature” was official support for running a terminal within vim. Along with this came a built-in debugger plugin, termdebug, which provid…

It seems like small thing, but it’s an engineering detail I’ve always had a lot of respect for.
Getting your messages without giving a third party your credentials and data
As it’s the 50th anniversary of the Apollo 11 moon landings, I thought this would be a great opportunity to live code a demonstration of using my new compiler to write a simple lunar lander game… but first, I’m going to port the compiler to generate code for an actual lunar lander. Yes, my target platform is the…
In the last post , we described a protocol that should satisfy the requirements and invariants established in the first post . Today we will look at formal verification with TLA+. Formal verification is just another (niche) tool in the toolbox. Some tools require more skill than others to use. So
There's nothing here. The Internet is far too dangerous right now. The blog may return in future, if I get around to it.
A look at what the newest generation of Java GCs can do
If you've ever hit the tab key while typing commands in the shell, you are familiar with the value of shell completions. Bash has some default completion behavior, which is why you can type hel<TAB> and end up with help . It is also possible to add additional completion scripts which define the completion behavior for…
