A bloom filter is one of those data structures you are probably already aware of, or have at least heard about. For those looking for a simple recap, they are a probabilistic data structure which can …
In 1999, Lutz Prechelt published a seminal article on the COMMUNICATIONS OF THE ACM (October 1999/Vol. 42, No. 10) called Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences , henceforth Java VS C , which seems to have later (March 2000) been expanded into a full paper, An empirical comparison…
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…
WebAssembly (Wasm) has many applications in the cloud-native world today – WASI, edge cloud computing, Proxy-Wasm, and cloud-native runtime for server
There has recently been some renewed discussion on Twitter about the limitation that the macOS sandbox places on the number of open files an app can access at once. Apps are still running into problems because of this limitation, and there is not a lot of technical detail available on it outside of Apple, so I’d like…
This is an introductory article about shell injection, a security vulnerability allowing an attacker to execute arbitrary code on the user's machine. This is a well-studied problem, and there are simple and efficient solutions to it. It's relatively easy to design library API in such a way as to shield the application…
Hello, if this is your first time reading this, I'm luna, one half of LavaTech and we provide continuous integration (CI) services for th...
I'm certainly not a world-class expert, but I have put my 10,000 hours of deliberate practice into programming. Here are 31 of my reflections on programming.
In the last six months the Firefox performance team has implemented changes to improve startup, responsiveness, security (Fission), and web standards. Startup and perceived startup Doug Thayer and Emma Malysz ...
A discussion of aggregation in PostgreSQL and how it integrates with the design of Timescale’s hyperfunctions.
Slitter is Backtrace’s deliberately middle-of-the-road thread-caching slab allocator, with explicit allocation class tags (rather than derived from the object’s size class). It’s mostly written in Rust, and we use it in our C backend server. Slitter’s design is about as standard as it gets: we hope to dedicate the…
by Eric Evans Perfectionism is a pitfall. For those who, like me, love elegant design and see its utility, there is a slippery slope waiting when a satisfying design does not emerge in a reasonable time. It takes constant self-discipline to recognize this and accept, let go, ship and move on – or return in...
The Maersk Triple-E Class container ship is 1,300 feet long, carries over 18,000 containers across 11,000 miles between Europe and Asia, and… Its entire crew can fit inside a passenger van. As a former naval architect and a current marketing consultant to startups, I found that
An excerpt from my book Coders at Work that I frequently find myself wanting to cite mostly because I get a kick out of someone having standing to call BS on Dijkstra:
A small, cool fact about SQLite is that its columns are flexibly typed. You can store any value in any column! Try it out: sqlite> create table t1 (v1 int, v2 varchar(10)); sqlite> insert into t1 values ("abc", "this string is longer than 10 characters!"); sqlite> select * from t1; abc|this string is longer than 10…

This beginner guide will help you understand how convolution neural networks (CNNs) work and what they are useful for.
JFrog finds a new supply chain attack targeting python developers using the PyPI repository
Some new minor leap second drama is coming up, and for once we can
Today’s show: How to quit your job and work on open source full time. This story has it all -- balancing side projects and full-time employment, building up enough supports to leave your job, and explaining quitting to your family and friends. And also: what do you do if your project succeeds, and then someone forks…
Whether your game surfaces its numbers to the player or not, odds are it has underlying systems that rely on them, and you use functions to determine how those numbers affect each other. In other words, a mathematical function is usually at the core of the answer to a bunch of frequent game design questions.
TL;DR Clojure is a great programming languages due to its functional nature, lack of objects / concentration on primitive values
Psycopg is the most popular PostgreSQL adapter for the Python programming language.
