<p>For years I’ve noodled around with various setups for a Python development environment. A couple of years ago <a href="https://jacobian.org/2018/feb/21/python-environment-2018/">I wrote about a setup I finally liked</a>; this is an update to that post.</p> <p>Bad news: this stuff still isn’t stable, and…
A riveting tale of how good data can lead to bad decisions.
This is an announcement regarding the resolution of the syntax for the await operator in Rust. This is one of the last major unresolved questions blocking the stabilization of the async/await feature, a feature which will enable many more people to write non-blocking network services in Rust. This post contains…
This blog post is one of those things that just blew up. From a tiny observation at work about odd behaviors of spinlocks I spent months trying to find good benchmarks, (still not entirely successf…
Or rather, an object is a set of functions that operate on implied data elements.
How to split up your large, complex, frontend codebases into simple, composable, independently deliverable apps.

As the man said, for every complex problem there’s a simple solution, and it’s wrong.
Link time optimization (LTO) is LLVM's way of implementing whole-program optimization. Cross-language LTO is a new feature in the Rust compiler that enables LLVM's link time optimization to be performed across a mixed C/C++/Rust codebase.
Occasional writings about Haskell.
As the final model release of GPT-2’s staged release, we’re releasing the largest version (1.5B parameters) of GPT-2 along with code and model weights to facilitate detection of outputs of GPT-2 models. While there have been larger language models released since August, we’ve continued with our original staged release…
I wrote a self-hosting C compiler which I named 8cc in 40 days. This is a log when I was writing it from scratch by myself in 2012. The code and its history are available at GitHub .
The received wisdom suggests that Unix’s unusual combination of fork() and exec() for process creation was an inspired design. In this paper, we argue that fork was a clever hack for machines and programs of the 1970s that has long outlived its usefulness and is now a liability. We catalog the ways in which fork […]
Aroma is a code-to-code search and recommendation tool that uses ML to make the process of gaining insights from big codebases much easier.
Dodrio is a new virtual DOM library that is designed to leverage the strengths of both Wasm’s linear memory and Rust’s low-level control by making extensive use of fast bump ...
The command line tool I created Sloc Cloc and Code (scc) (which is now modified and maintained by many other excellent people) counts lines of code, comments and makes a complexity estimate for files …
Living and working in the big apple comes with big rent.
Update: Due to lack of interest/use, in June 2021 this site was shut down and user data (emails, names, search alerts) deleted from all systems and backups. For Extramaze LLC I'm using Racket in a commercial project -- a search engine with email alerts fo...
I've just finished the final rewrite of my website. I'm not lying: this is the last time I'm ever going to do it. This website has gone through countless rewrites – from WordPress to Jekyll to multiple static site generators of my own – but this is the final one. I know so, because I've found the ultimate method for…
Using vectorized processing in an execution engine makes more efficient use of modern CPUs by changing the data orientation (from rows to columns) to get more out of the CPU cache and deep instruction pipelines by operating on batches of data at a time.
gRPC 1.0 was released in August 2016 and has since grown to become one of the premier technical solutions for application communications. It has been adopted by startups, enterprise companies, and open source projects worldwide. Its support for polyglot environments, focus on performance, type safety, and developer…
The nuance between timestamp with and without time zone
My job involves a lot of staring at large numbers, mostly latencies in nanoseconds, and picking out magnitudes like microseconds. I noticed myself constantly...
Ruby apps can use a lot of memory. But why? Various people in the community attribute it to memory fragmentation, and provide two “hacky” solutions. Dissatisfied by the current explanations and provided solutions, I set out on a journey to discover the deeper truth and to find better solutions.
This blog post is a slightly edited version of the live transcript of the talk I gave at RustFest 2019 in Barcelona on November 10th, 2019. As it's a transcript some parts of it are a bit repetitive or badly worded, but I hope the message behind the talk will be conveyed by this post anyway.
This post describes a compile-time technique for catching use-after-move bugs in modern C++. It’s currently used to prevent some mistakes in the Serenity Operating System.
