Improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts. Achieve this by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. Lay a…
As a rule, "sophisticated" progrmming is pretty boring - optimizing the unnecessary to speed up the uninteresting. Here, however, is an incredibly sophisticated package intended for fun and games. The more you know about software, the more astounded you will become as you read this.
It's difficult to get the Windows Console to display Unicode characters, so here's a C++ WinForms program that will display the arguments in a TextBox.

Learn about how we built a CI-native AI code reviewer using OpenCode that helps our engineers ship better, safer code.
An interview with Felix Winkelmann about CHICKEN Scheme, the SPOCK Scheme-to-JavaScript compiler, and what motivates him to keep programming.
Recently NixOS was posted to the Haskell reddit, and seems to have been received well. In the comments I mentioned that NixOS allows me to be a more productive Haskell developer, and I would like to discuss how I am using the features offered by NixOS. Before we get into those details, allow me to briefly summarise…
For the purposes of this post, I will be talking about JavaScript objects using syntax defined in ECMAScript 5.1. The basic semantics existed in Edition 3, but they were not well exposed. A Whole New Object In JavaScript, objects are pairs of keys and values (in Ruby, this structure
I wanted to know how a modern C compiler like clang would process the following C code: #include <stdint.h> int count(uint64_t x) { int v = 0; while(x != 0) { x &= x - 1; v++; } return v; } Can you guess? popcntq %rdi, %rax That is right. A fairly sophisticated C function, … Continue reading The surprising cleverness…
Ah, C. The best lingua franca we have… because we have no other lingua francas. Linguae franca. Surgeons general? C is fairly old — 44 years, now! — and comes from a time when there were possibly more architectures than programming languages. It works well for what it is, and what it is is a relatively simple layer of…
asm.js is an easy-to-optimize subset of JavaScript. It runs in all browsers without plugins, and is a good target for porting C/C++ codebases such as game engines - which have ...
A while ago there was an interesting thread on the Julia Discourse about the “state of machine learning in Julia”. I posted a response discussing the differences between Julia and Python (both JAX and PyTorch), and it seemed to be really well received! Since then this topic seems to keep coming up, so I thought I’d…
"JVM Anatomy Quarks" is the on-going mini-post series, where every post is describing some elementary piece of knowledge about JVM. The name underlines the fact that the single post cannot be taken in isolation, and most pieces described here are going to readily interact with each other.

Quick edit: While I work on a proper update, I'll note here that several posters on reddit and hackernews have pointed out ways to bring the total size of the program down to 105 bytes while still printing the full "Hello, world!" Much credit goes to Josh Triplett , who produced the 105-byte version which you can find…
If you read the LLVM 2.7 release notes carefully you would have noticed that one of the new external users is the Glasgow Haskell Compiler (GHC). As the author of the LLVM backend for GHC, I have been invited to write a post detailing the design of the backend and my experiences with using LLVM.
The setup.py interface is an old convention from distutils, one that has bugs that cannot be fixed to bring it into line with modern Python packaging approaches. As a result, all direct...
One of the big features for Go 1.1 is the new scheduler, contributed by Dmitry Vyukov. The new scheduler has given a dramatic increase in performance for parallel Go programs and with nothing better to do, I figured I'd write something about it.
posted by Matthew Flatt For background information about Racket on Chez Scheme (a.k.a. Racket CS), see the original announcement, the January 2018 report, the report at Scheme Workshop 2018, the January 2019 report, the ICFP experience report, an...
I love science. Not the “space is beautiful” faux-science, but the process of doing science. Hours spent calibrating equipment, cross-checking cites of cites of cites, tedious arguments about p-values and prediction intervals, all the stuff that makes science Go. And, when it does happen, the drama. I also want us to…
In 2010ish, we tried to roll out a feature ( Treasury ) using MongoDB. It was an interesting experience. I learned quite a bit in the process. I wrote about what I was thinking at the time here . But for the most part it was an abject failure and Ryan Young wound up porting the entire thing to the MySQL shards which…
If you ignore the practical issues of computers like size, weight, cost, heat, and so on, what do you really need in a programming language? Let's play around with this question.
