Learn about some new ways students can code in the browser. With online integrated development environments (IDEs), students can get right to work in a web browser, avoiding software conflicts that might happen on their local machines.
Vary support is now available in Cache Rules on every plan. You can normalize known negotiation headers, pass exact values through to the origin when those small differences matter, or bypass cache when the variation is too unpredictable.
Many times a scientist is choosing a programming language or a software for a specific purpose. For the field of scientific computing, the methods for solving differential equations are one of the important areas. What I would like to do is take the time to compare and contrast between the most popular offerings. This…
Hey all. TinyKVM was open-sourced this february and since then I’ve been working on some things that are very much outside of the scope of…
This post will explore the famous winner of the first IOCCC contest, dive into the story behind the code, and even display the original source programs!
There are so many NoSQL systems these days that it's hard to get a quick overview of the major trade-offs involved when evaluating relational and non-relational systems in non-single-server...
Training gaming agents is an addictive game. A game of sleepless nights, grinds, explorations, sweeps, and prayers. PufferLib allows anyone with a gaming computer to play the RL game, but getting from “pretty good” to “superhuman” requires tweaking every lever, repeatedly.
Last weekend, I attended GitHub's PyCodeConf in Miami Florida and had the opportunity to give a talk on array-oriented computing and Python....

In this article I give a brief tour of a program analysis technique called symbolic execution. As the title indicates, I aim to explain both the intuition behind the technique, and also the details of a simple implementation. My intended audience is professional programmers who have no background in program analysis.
Sorry, this post will read like a “dear diary” entry rather than some life-changing HN-worthy guidance. Back in November 2020, almost on a whim I started work on a new parser for the Ruby programming language. It was almost exactly a year after I had started working on my compiler project (I hope to write a longer…
Musings on navigating the tech bubble with philosophy and self-improvement.
Today, we’re announcing the availability of PyTorch 1.5, along with new and updated libraries. This release includes several major new API additions and improvements. PyTorch now includes a significant update...
TableGen is a language used within the LLVM project for generating a variety of files, when manual maintenance would be very difficult. For example, it is used to define all of the instructions that can be used on a particular architecture.
This beginner guide will help you understand how convolution neural networks (CNNs) work and what they are useful for.
Functional programming and immutability are hot right now. On one hand, this is pretty great as there’s lots of nice things about functional programming. On the other hand, people get a little overzealous and start claiming that imperative code is unnatural or that purity is always preferable to mutation. I think that…
I am a big fan of Dave Whyte’s vector animations, like this one: It was generated using a special animation language called Processing (here is Dave …
We describe a full implementation of algebraic effects and handlers as a library in standard and portable C99, where effect operations can be used just like regular C functions. We use a formal operational semantics to guide the C implementation at every step where an evaluation context corresponds directly to a…
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…
Liftoff is a new baseline compiler for WebAssembly, shipping in V8 v6.9.
The story of changing a single byte
Propositional logic was discovered by Stoics around 300 B.C., only to be abandoned in later antiquity and rebuilt in the 19th century by George Boole’s successors. One of them, Charles Peirce, saw its significance for what we now call logic circuits, yet that discovery too was forgotten until the 1930s. In the ’50s…
I know that a lot of people struggle with understanding the memory model introduced in C11/C++11. In a recent conversation I was alerted to the existence of this blog post, which while correct (by …
This post introduces Arrow Flight SQL, a protocol for interacting with SQL databases over Arrow Flight. We have been working on this protocol over the last six months, and are looking for feedback, interested contributors, and early adopters.
PostgreSQL 11 offers the best OVER clause support among its competitors, true procedures, and improvements in FETCH FIRST and XML.
