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…
Let's assume Go has one killer feature – cheap concurrency – not present in any other language with similar serial performance (ruling out say Erlang). And let's agree that it gives Go its perfect niche – and we're only discussing uses of Go outside that niche from now on. So we won't come back to concurrency till the…
Note : This article is for an obsolete version of Rust, and has been superceded by the slightly less misleadingly named "A Practical Intro to Macros in Rust 1.0" .
2013 Update: I was young and stupid when I wrote this. I fear that Haskell is doomed to succeed. — Tony Hoare I ♥ Lisp. I think it's t...
Over the past year, the WebKit project made tremendous progress on the ability to optimize JavaScript applications. A major part of that effort was the introduction of the Fourth Tier LLVM (FTL) JIT.
It makes many aspects of JavaScript sane and convenient, and you get a compilation check that verifies syntax, however it still suffers greatly from weak-typing.
Recently I gave an itemis internal talk about basic functional programming (FP) concepts. Towards the end I made a claim that objects and their blueprints (a.k.a. classes) have severe downsides and that it is much better to "leave data alone", which is exactly how Clojure and Haskell treat this subject.
Well, not quite but let's start from the beginning.
WARNING: 2018-04-12 : The code snippets for this post are no longer available. This is just as well anyway, since they all depended on an unstable internal compiler interface, which hasn’t existed for years.
I have decided to do a two-part series here praising Perl in part 1 and PostgreSQL in part 2. I expect that PostgreSQL folks will get a l...
If The `if` statement is pretty much the same in Rust as C++. One difference is that the braces are mandatory, but brackets around the ...
[For your winter reading pleasure, we're pleased to present this three-part series of new material by Bjarne Stroustrup. Part one is here , part two is here . Today we complete the series just in time for the holidays. Enjoy. -- Ed.]
This is a sketch of proposed enhancements to the Java Virtual Machine instruction set, and secondarily to the Java Language, to support small immutable, identityless value types . (They may also be considered as identityless aggregates, user-defined primitives, immutable records, or restricted classes.) This is an…
Web browsers do a lot of calculations on geometric coordinates, in many different coordinate systems and units of measurement. For example, a browser may need to translate a position expressed ...
Some time ago i started to write series of blog posts about assembly programming for x86_64. You can find it by asm tag. Unfortunately i wa...
Hello everyone! Time for a bit of a diversion towards one of my favorite projects, Hy ! (I'm an occasional committer, but the main mastermind behind the project is my good friend Paul Tagliamonte .) For those of you who don't know, Hy is a Lisp that transforms into the Python AST. Even more fun: you can import .hy…
Rust is a systems language and therefore must give you raw access to memory. It does this (as in C++) via pointers. Pointers are one area w...

An introduction to the Go context package.
The start of September brings a close to the Go 1.4 merge window . From now until the release in December, only bug fixes and tweaks will be accepted.
