Update: I've made several edits to the post since Aleksey Shipilëv was kind enough to suggest many corrections and improvements.If you closely follow JVM development scene, you've probably noticed ...
Mocking is a powerful technique for isolating tests. But yours isn’t working. Why!?

GitHub Actions are still in beta and are changing quickly. But if you are looking to get started the possibilities are endless.
Parallelism in PostgreSQL was implemented as part of multiple features which cover sequential scans, aggregates, and joins.
This post explores unit and integration testing in no_std executables. We will use Rust’s support for custom test frameworks to execute test functions…
(For the avoidance of doubt, I have nothing to do with hiring at my employer. This test is probably deeply problematic in ways you'll angrily Tweet me about.) I'd like to tell you a story! I am a teenager applying for temp jobs. It's the late 1990s and the temp agency have asked me to take a Microsoft Office test. You…
"Big integers" have landed in Javascript, at least in Firefox and Chrome. One of my favorite things to do with high precision arithmetic is to calculate digits of π. From scratch, that is, using only addition, subtraction, multiplication, and division.
Over the years I’ve found myself with a weird amount of knowledge about how types and ABIs in Rust work, and I wanted to write it all down in one place so that… it’s written down in one place. Much of this information can or should be found in the Rust Language Reference and the Rustonomicon .
Any problem in computer science can be solved with another level of indirection. Except for the problem of too many layers of indirection.
React Hooks can be frustrating despite their popularity and widespread use. Learn about some of the drawbacks to using React Hooks.
Write small blocks of code. How small? Here's how small.
When designing or, in some cases, implementing a programming language with built-in support for Unicode strings, an important decision must be made about how to represent or encode those strings in memory. Not all representations are equal, and there are trade-offs between different choices.
Bjarne Stroustrup is the creator of C++. We got a chance to chat with him about the “golden years” of Bell Labs and the top C++ questions on Stack Overflow.
I had a student (Fred Smith) who worked on extensions to Popcorn (the predecessor to Cyclone) that supported run-time code generation in a lightweight fashion. Here’s a paper describing part of the system: https://ecommons.cornell.edu/handle/1813/5812 . Fred’s thesis had a bunch more.
Assuming you're in the unusual position of actually having budget for quality, here's what to spend it on.
A post describing how C programs get to the main function. Devicetree layouts, linker scripts, minimal C runtimes, GDB and QEMU, basic RISC-V assembly, and other topics are reviewed along the way.
In this second installment of the machine learning from scratch we switch the point of view from regression to classification: instead of estimating a number, we will be trying to guess which of 2 possible classes a given input belongs to. A modern example is looking at a photo and deciding if its a cat or a dog.
Martin Sebor looks at C string handling functions used to copy and concatenate strings and examines ways to improve their efficiency.

What a great book Designing Data-Intensive Applications is! It covers databases and distributed systems in clear language, great detail and without any fluff. I particularly like that the author Ma…

Multi-value is a proposed extension to core WebAssembly that enables functions to return many values, among other things. It is also a prerequisite for Wasm interface types. Nick Fitzgerald has ...
Summary: jq rocks for speedy JSON mangling. Use it to make powerful git clean filters, e.g. when stripping out unwanted cached-data from Jupyter notebooks. You can find the documentation of git 'clean' and 'smudge' filters buried in the page on git-attributes , or see my example setup below.
