It's normal for post-quantum cryptography to be rolled out as an extra layer of security on top of traditional pre-quantum cryptography, rather than as a replacement .
In this blog post, we walk through how to use Matrix Cores in HIP kernels, with a focus on low-precision data types such as FP16, FP8, and FP4, as well as the new family of Matrix Core instructions with exponent block scaling introduced in the AMD CDNA™4 architecture. Through code examples and illustrations, we…
The Financial Times reports that the U.K. is once again demanding that Apple create a backdoor into its encrypted backup services. The only change since the last time they demanded this is that the order is allegedly limited to only apply to British users. That doesn’t make it any better.The demand...
Every day, corporations track our movements through license plate scanners, building detailed profiles of where we go, when we go there, and who we visit. When they do this to us in violation of data privacy laws, we’ve suffered a real harm—period. We shouldn’t need to prove we’ve suffered...
Many software engineers are fatalistic about company politics. They believe that it’s pointless to get involved, because: Technical decisions are often made for…
Notes from setting up a truly minimal self-hosted email server with Postfix and OpenDKIM. Covers TLS, SPF, DKIM, DMARC, DNS, reverse DNS, multiple domains, and delivering to Gmail.
Flock Safety, the police technology company most notable for their extensive network of automated license plate readers spread throughout the United States, is rolling out a new and troubling product that may create headaches for the cities that adopt it: detection of “human distress” via audio. As...
Nvidia's $110B vendor financing strategy mirrors Lucent's telecom bubble playbook. Analyzing customer concentration, GPU-backed debt, depreciation schedules & cash flow patterns to assess AI bubble risks.
A friend called me last week. Someone who’d built web applications back for a long time before moving exclusively to backend and infra work. He’d just opened a modern React codebase for the first time in over a decade.
The first project that I worked on for Apple after starting in August 1979 was writing low level software for the Silentype printer (see What Hath Woz Wrought ) , a cute, inexpensive thermal printer for the Apple II, that was based on technology licensed from a local company named Trendcom. In typical Apple fashion…

We have been learning quickly from how people are using Sora and taking feedback from users, rightsholders, and other interested groups. We of course spent a lot of time discussing this before...
Who owns the major VPN companies like Express, Nord, and Surfshark? We take you through an interactive map of the murky world of VPNs.
Private practices are vanishing as more doctors join large hospital systems. This increasing consolidation is reducing competition and raising prices, according to a study co-authored by Yale SOM’s Fiona Scott Morton.
Andrew Kelley famously (or infamously, depending on your views) said "the compiler is too damn slow, that's why we have bugs." 1

At one level, this question is not very fair, because an answer to it as stated would be that one simply does not use doubly linked lists. They have been popular in introductory computer science lectures because they are a neat way to explain pointers in a data structure that's easy to draw on a whiteboard, but they…
I recently migrated my self-hosted services from a VPS (virtual private server) at a remote data center to a physical server at home. This change was motivated by wanting to be in control of the hardware and network where said services run, while trying to keep things as simple as possible. What follows is a…
Author's note: I wrote this in March 2023, but just published in October 2025. I held back from publishing this originally for fear that I was being sensationalist. But with the launch of Sora 2, I couldn't not share these thoughts. I only regret I didn't publish it 2 years ago.
What is an Economics PhD worth in 2025?
What is OpenAI? I realize you might say "a foundation model lab" or "the company that runs ChatGPT," but that doesn't really give the full picture of everything it’s promised, or claimed, or leaked that it was or would be. No, really, if you believe its leaks to
Correctness in the face of cancellations: a written version of my talk at RustConf 2025.
There’s this popular idea that socially anxious folks are dying to be liked.
Sharing my thoughts and current projects.
Lately I’ve heard a lot of stories of AI accidentally deleting entire codebases or wiping production databases . But in my case it was the other way around. I removed some working code and the LLM helped me to recover it.
