People misuse queues all the time. The most egregious case being to fix issues with slow apps, and consequently, with overload. But to say why, I'll need to take bits of talks and texts I have around the place, and content that I have written in more details about in Erlang in Anger .
When I teach courses on Python for scientific computing, I make this point very early in the course, and tell the students why: it boils down to Python being a dynamically typed, interpreted language, where values are stored not in dense buffers but in scattered objects. And then I talk about how to get around this by…
Alright, guys. Today I want to talk about programming. It is interesting to note that I have solved it. Yes, I solved it. Here are my…
Choose to do only the things that nobody else can do.
(Recap: I founded the curl project, I am still the lead developer and maintainer) When asking curl to get a URL it'll send the output to stdout by default. You can of course easily change this behavior with options or just using your shell's redirect feature, but without any option it'll spew it out to … Continue…
There are several reasons why one should prefer L A T E X to a WYSIWYG word processor like Microsoft Word: portability, lightness, security are just a few of them (not to mention that L A T E X is free ). There is still a further reason that definitely convinced me to abandon MS Word when I wrote my dissertation: you…
There has been a lot of discussion lately about Rust’s allocator story, and in particular our relationship to jemalloc. I’ve been trying to catch up, and I wanted to try and summarize my understanding and explain for others what is going on. I am trying to be as factually precise in this post as possible. If you see a…

Compiler Design in C Download a copy! My book Compiler Design in C is now, unfortunately, out of print. You can download a complete copy, with the above button (pdf 19.1Mb OCR/Searchable—thanks to Marvin Hernández for adding the OCR). If you don’t want to print it out (the book is 984 pages long), you can…
We’ve always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we’re performance wonks (guilty!), but because we think speed is a competitive advantage. There’s plenty of experimental data proving that the slower your website loads and displays, the less people

An introduction to the idea that code should be approached with a mindset towards compressing it semantically, rather than orienting it around objects.
Emacs switched the version control system from Bazaar to git yesterday, so now is the time to start hacking away at Emacs. Emacs: The Best Thing Since Sliced Bread If It Wasn’t For The Fact T…
If there’s one thing to know about distributed systems, it’s that they have to be designed with the expectation of failure. It’s also safe to say that most software these days is, in some form, distributed—whether it’s a database, mobile app, or enterprise SaaS. If you have two different processes talking to each…

There are some pretty strong statements about types floating around out there. The claims range from the oft-repeated phrase that when you get the types to line up, everything just works, to “not relying on type safety is unethical (if you have an SLA)” 1 , " It boils down to cost vs benefit, actual studies, and…

In the last post I talked about immutable stacks & queues. This post will be on immutable vectors. We want to support 3 operations:
I think this might be my last blog entry on the subject of building SBCL for a while.
I use the Sherlock Holmes method of debugging software. This means working backwards from a symptom to the series of causes which tell a story of the entire bug. It works for production outages and during development. Something that recently happened at my startup should be instructive.
Programming languages new (Java) and old (Fortran), and their compilers, still lack competent support for features of IEEE 754 so painstakingly provided by practically all hardware nowadays. […] Programmers seem unaware that IEEE 754 is a standard for their programming environment, not just for hardware. William Kahan
