Building a highly-available web service without a database
If you’ve ever built a web service or a web app, you know the drill: pick a database, pick a web service framework (and in today’s day and age, pick a front-end framework, but let’s not get into that). This has been the case for several decades now, and people don’t stop to question if this is still the best way to build a web app. Many things have changed in the last decade: Disk is a lot faster
xz-backdoor.md FAQ on the xz-utils backdoor (CVE-2024-3094) This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on. Background On March 29th, 2024, a backdoor was discovered in xz-utils, a suite of software that gives developers lossless compression. This package is commonly used for c

Orange Tsai tweeted a few hours ago about “One of [his] PHP vulnerabilities, which affects XAMPP by default”, and we were curious to say the least. XAMPP is a very popular way for administrators and developers to rapidly deploy Apache, PHP, and a bunch of other tools, and any bug that could give us RCE in its default installation sounds pretty tantalizing. Fortunately, for defenders, the bug has o
Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen. The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,
Never* use Datagrams Click-bait title, but hear me out. TCP vs UDP So you’re reading this blog over the internet. I would wager you do a lot of things over the internet. If you’ve built an application on the internet, you’ve undoubtedly had to decide whether to use TCP or UDP. Maybe you’re trying to make, oh I dunno, a live video protocol or something. There are more choices than just those two bu
I often come across developers who know the mechanics of Python error handling well, yet when I review their code I find it to be far from good. Exceptions in Python is one of those areas that have a surface layer that most people know, and a deeper, almost secret one that a lot of developers don't even know exists. If you want to test yourself on this topic, see if you can answer the following qu

What the New York Times Missed: 71 More of the Best Books of the 21st Century
Susanna Clarke, Jonathan Strange & Mr. Norrell (2004) I should not have been surprised that the NYT list skewed heavily away from genre fiction—but missing Susanna Clarke’s world-changing doorstopper of a debut is a particular head-scratcher. On paper, the book still seems daunting in an almost comical way: a Regency-era epic (with footnotes and extensive digressions on philosophy, magic, politics
Everything a developer needs to know about Generative AI for SaaS
Everything a developer needs to know about Generative AI for SaaS Few months ago, I knew almost nothing about AI. I used ChatGPT and Co-Pilot (I'm civilized, after all), but a lot of the content around AI was Greek to me. Terms like models, transformers, training, inference, RAG, attention, and agents were unfamiliar. Last week, I have completed my first end-to-end AI-based product: AI Code Assist
NOTE: This is based on, but completely rewritten, from a Twitter post: https://x.com/TheGingerBill/status/1802645945642799423 TL;DR It makes Go feel too “functional” rather than being an unabashed imperative language. I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024). From what I can gather, many people seem to dislike the design. I wanted to give m

This is why you should never use parser combinators and PEG
Let me tell you why you should (nearly) never use PEG (parsing expression grammars). Nearly everything I will say applies to parser combinators (parsec in Haskell, nom in Rust), too. So, don't use PEG. Use CFGs (context-free grammars) instead. They are more natural. I feel that CFGs more naturally represent how we think. Thus when you have some language in your head and you try to write it down as
Engineering for Slow Internet How to minimize user frustration in Antarctica. Hello everyone! I got partway through writing this post while I was still in Antarctica, but I departed before finishing it. I’m going through my old draft posts, and I found that this one was nearly complete.

This post could’ve been titled “Nostr vs ATProto”, but that really isn’t what I wanted to do here. While I will be comparing and contrasting them a lot, and that’s kind of even the point of writing this, I didn’t want to really pit the two against each other at all, and especially not with the title. I also want to try avoiding commenting on the differences between the communities that have formed

If you have followed my web development tutorials you must have seen me use utcnow() a lot, so I will clearly need to re-train myself to use an al

How I Have Fun With Rust
Ruby is my main programming language, but in the last few months, I’ve been playing with Rust on side projects. Sometimes it was super fun, sometimes it was ultimately frustrating. To ensure I always break even, I came up with a few guidelines for myself. Take the easy way out A systems programming language introduces lots of new (and often hard) concepts. Some of them are similar but have trade-o

I grew up learning to program in the late 1980s / early 1990s. Back then, I did not fully comprehend what I was doing and why the tools I used were impressive given the constraints of the hardware we had. Having gained more knowledge throughout the years, it is now really fun to pick up DOSBox to re-experience those programs and compare them with our current state of affairs. This time around, I w
One of the things I like to do is compare how different languages solve the same problem — especially when they end up having very different approaches. It’s always educational. In this case, a bunch of us have been working hard on trying to get reflection — a really transformative language feature — into C++26. Fundamentally, reflection itself can be divided into two pieces: Introspection — the a

Interview: Kenta Cho (Japanese indie game developer) ⌘I Get Info
Kenta Cho is a Japanese indie game developer, who has been active since the 1980s. He became well-known in the West in the early 2000s with a series of bullet hell shoot-em-ups. In 2021 he created a total 139 games, which is one hell of a lockdown project. In early 2024 his game Paku Paku went viral, as “1D Pac-Man”, a year after it was made. I reached out to him with some questions and he was gra
How bad are search results? Let's compare Google, Bing, Marginalia, Kagi, Mwmbl, and ChatGPT
Marginalia does relatively well by sometimes providing decent but not great answers and then providing no answers or very obviously irrelevant answers to the questions it can't answer, with a relatively low rate of scams, lower than any other search engine (although, for these queries, ChatGPT returns zero scams and Marginalia returns some). Interestingly, Mwmbl lets users directly edit search res
