Everyone knows that on most systems you can specify IPv4 addresses just 4 decimal numbers separated with periods (dots). Example: 192.168.0.1 Useful when you for example want to ping your local wifi router and similar. "ping 192.168.0.1" Other bases The IPv4 string is usually parsed by the inet_addr() function or at…
Flash cartridges (= "carts") are commonly used to run Game Boy ROMs, such as homebrew games or dumped officially released games, on real hardware. Different kinds of flash carts with various features and performance characteristics have been available for a long time, but flash carts have in general the reputation of…
How I reduced Rust incremental debug build times on macOS from 14 seconds down to 4 seconds.
This article is the sequel to A Universal Async Abstraction for C++ , in which I talk about the Executor proposal targeting C++23. Quite a bit happened since then.
I'm afraid I'm not accepting new requests for review. I have reviewed all the ones I've received before 2022-03-24.
JavaScript implementation of so-called Seam Carving algorithm for the content-aware image resizing and objects removal. Dynamic programming approach is applied to optimize the resizing time.
The perspective of an ignorant computer science undergrad
A look back and forward on PHP
First there was REST, then GraphQL made RPC cool again, but maybe we need to come full circle with SQL over HTTP.
Lately I’ve been seeing lots of anecdotes from people trying to get into Rust who get really hung up on strings (&str, String, and their relationship). Beyond Rust’s usual challenges around ownership, there can be an added layer of frustration because strings are so easy in the great majority of languages. You just…
Add WebAssembly, get performance. Is that how it really works?
A professional programmer delivers value through the authoring and maintaining of software that solves problems. (There are other important ways for professional programmers to deliver value but this post is about programming.)
"Know your enemy, know yourself, and in a hundred battles you will never be defeated"
I wrote Gitlet to show how Git works under the covers. I wrote it to be readable. I commented the code heavily.
It’s been two years since our company decided we’ll pick NativeScript to create and maintain our Android App.
What console.log() does, where to find console logs in the browser and Node.js, with examples, plus console methods like table(), group() and time().
Mugo is a single-pass compiler for a tiny subset of the Go programming language -- just enough to compile itself.
The switch true pattern isn't well known but it is incredibly useful. It's not a JavaScript specific pattern, but I use it in almost every single project.
In shell scripting you sometimes come across comparisons where each value is prefixed with "x". Here are some examples from GitHub:
People appear to enjoy the blog posts about me porting different compilers to OpenBSD . What I would like to do for the next couple of posts beginning with this one is to take a step back and de-complexify these programs. Both the D compiler and the GNU Modula-2 compiler are highly complex pieces of software. But at…
A bug that plagues thousands of open-source ML projects.
This post is a basic introduction to running HTTPS servers and clients in Go using TLS. It assumes some familiarity with public-key crypto. Feel free to check out my earlier posts about RSA and the Diffie-Hellman Key Exchange ; TLS uses the elliptic-curve version of Diffie-Hellman. I won't be covering how the protocol…
Yesterday I found myself googling how to do something that I’d think it was pretty standard: How to download multiple files from AWS S3 in parallel using Python? After not finding anything reliable in Stack Overflow, I went to the Boto3 documentation and started coding. Something I thought it would take me like 15…
Or, “how not to GIS”.
I have a hunch that once people saw the economic potential of software, they started looking for ways to "scale it up" and we haven't stopped searching yet.
Building Brainf∗ck interpreter for the 21 century, with all the best systems design practices in mind. Think of Brainf∗ck-as-a-service cloud solution!
Around 1990, Richard Stallman (RMS) and I were writing the GNU C library getopt() and he wanted to extend it to support long (multi-character) option names for user-friendliness. He considered Unix…
