In React, we don't update the DOM directly, we tell React what we want the DOM to look like, and React tackles the rest. But how exactly does it do this? In this tutorial, we'll unpack exactly when and why React re-renders, and how we can use this information to optimize the performance of our React apps.

For the last four months I’ve been developing a custom container image builder, collaborating with Outerbounds1. The technical details of the builder itself might be the topic of a future article, but there’s something surprising I wanted to share already: you can use S3 as a container registry! You heard it right…
Scott Kupor at Andreessen Horowitz has a post today on some potential downsides of 10-year exercise periods for startup employees’ stock options. I’d recommend reading the whole thing for context here, but to summarize: * He argues that allowing employees who leave a company to keep their optio...
On September 15, 2020, a small group of people worked through the night to rescue over 9.6MM USD from a vulnerable smart contract. This is our story.
One of my bucket list items since I read my first party report back in 1991 was to attend a european demoparty and compete in a compo. I competed at NAID ’96 and placed there, which was awes…
Take a look at these two QR codes. Scan them if you like, I promise there's nothing dodgy in them. Left is upper-case HTTPS://EDENT.TEL/ and right is lower-case https://edent.tel/ You can clearly see that the one on the left is a "smaller" QR as it has fewer bits of data in it. Both go to the same URl, the only…

Just so you know, x86 machine-code is now a "high-level" language. What instructions say, and what they do, are very different things. I m...
Have you ever wondered how a compiler works, but you never found courage to find out? Then this series of articles is for you. I have never had the chance to look under the hood either, but one week-end I have decided to to write a translator from the esoteric programming language wend (short for week-end), which I…
It’s 1986 and you’ve got a 31 tons of copper, in the form of a giant 46 meter tall statue, that’s looking a bit worse for wear.
It turns out that LLMs can make CAD models for simple 3D mechanical parts. And, I think they’ll be extremely good at it soon.
This article explains the mechanics behind traceroute, from IP headers and TTL fields to ICMP messages. Learn why traceroute is a crucial tool for network diagnostics, how it differs from ping, and how to interpret its output. Ideal for network administrators, IT professionals, and curious users looking to understand…
I was personally useless for most of the Spring of 2020. There was a period of time, though, after the peak in coronavirus cases here in NYC and before the onslaught of police violence here in NYC that I managed to scrounge up the motivation to do something other than drink and maniacally refresh my Twitter feed. I…

I read yesterday evening that our portfolio company Twilio, which priced its IPO last night, is going to live code from the NYSE this morning. That brought a powerful flashback to the first time I met Jeff Lawson, founder and CEO of Twilio. It was 2008 in our old offices on the 14th floor of […]
The initial, feverish enthusiasm for large language models (LLMs) is beginning to cool, and for good reason. It’s time to trade the out-of-control hype for a more pragmatic, even “boring,” approach. A recent MIT report shows that 95% of companies implementing this technology have yet to see a positive outcome. It’s…
In computing, “laziness” is a broad term, generally referring to not doing any work unless you need it. Whereas its opposite is “eagerness,” doing as much work as possible in case you need it later.
Shenzhen I/O is a brilliant game. In case you haven’t heard of it, it’s a game about programming micro-controllers. It distills programming down to the fun parts, removing the inertia, …
I built a magical meme search engine using siglip/CLIP and vector encoding images. It was a fun way to learn about this powerful technology. I'm sharing the …
