One of my recent hobby projects was a blocks-based tool for doing basic data science , and I was very pleased when its test suite reached 100% line coverage. However, Inozemtseva2014 found that code coverage is a poor predictor of how effective a test suite is at detecting bugs once the size of the test suite is…
Up until now, GraalVM has offered two ways to run Java programs: using the Java HotSpot VM with the GraalVM JIT (just-in-time) compiler…
We’ve scaled Kubernetes clusters to 7,500 nodes, producing a scalable infrastructure for large models like GPT-3, CLIP, and DALL·E, but also for rapid small-scale iterative research such as Scaling Laws for Neural Language Models.
Some highlights of the Julia 1.7 release.

Mozilla has been fuzzing Firefox for a while. It has proven to be one of the most efficient ways to identify quality and security issues.
A case study of how Elixir is being used at Mozilla.
Our algorithm has the peculiar property that, roughly speaking, the longer the pattern is, the faster the algorithm goes. Furthermore, the algorithm is ``sublinear'' in the sense that it generally looks at fewer characters than it passes. The algorithm is described in
Get a closer look at how the Shenandoah garbage collector adds concurrent thread-stack processing, and reliable sub-millisecond pauses, in OpenJDK 17.
Generics is entering the language change proposal process
Open-source, swappable packages and an AI that assembles them into full-stack apps that scale.
The Parcel team is beyond excited to announce that v2.0.0 stable is now available! 🎉
This is quite the big update: you can now choose from 4 programming languages for your microStudio project: **microScript**, **Python**, **JavaScript** or **Lua**! All this still from your web browser. With any of these 4 languages, you have access to all the microStudio goodness: live edit your code, live help and…
TL;DR Clojure is a great programming languages due to its functional nature, lack of objects / concentration on primitive values
UPDATED July 2023: How to use EXPLAIN ANALYZE in PostgreSQL, learn tools to visualize the output. See query execution time and row count.
April Fool's may be over, but once we set up a system to react every time someone typed Command+C, we realized there was also an opportunity to learn about how people use our site. Here’s what we found.
Why does it take so long to build software? We hear variations of this question frequently: Why is building software so expensive? Why is my team delivering software so slowly? Why am I perpetually behind schedule with my software? There is a good reason we hear these questions over and over. Businesses need more and…
The new sparse index feature makes it feel like you are working in a small repository when working in a focused portion of a monorepo.
In this essay, Carson Gross gives an analysis of Rich Harris's talk 'Have Single-Page Apps Ruined the Web?', exploring the debate between Single-Page Applications (SPAs) and Multi-Page Applications (MPAs). Carson examines Harris's criticisms of both approaches and proposes hypermedia-oriented solutions using htmx…
