A cryptographic tag developed at MIT uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item’s surface.
When Simplicity is Preferrable to Efficiency
We have been encountering significant problems with Intel CPU stability. Despite all released microcode, BIOS, and firmware updates, the problem remains unresolved.
As a consultant, I have been called in to review and, in many cases, replace dozens of half-finished, abandoned, and sometimes forgotten data infrastructure projects.

Async/await, or "async IO", is a new-ish Rust added async/await in 2019. For comparison, C# added it in 2012, Python in 2015, JS in 2017, and C++ in 2020. language feature that lets our programs do more than one thing at a time. It's sort of an alternative to multithreading, though Rust programs often use both…
Division is quite an expensive operation. For instance, latency of the 32-bit division varies between 10 and 15 cycles on the Cannon Lake CPU, and for Zen4 this range is from 9 to 14 cycles. The latency of 32-bit multiplication is 3 or 4 cycles on both CPU models.
My main project is to create an executable spec of the Intel Architecture but, every now and then, I get to take a broader look at ISA specifications and think about the strengths and weaknesses of other ISA specs: what makes them work well; and what techniques they could borrow from other specifications. Earlier this…
What did you do at work today? How about last week? I spent a couple of days in quarterly business reviews, and wrapped up yearly planning activities for AWS Data Exchange and AWS Marketplace. I also added some unit tests to a project that I am onboarding into.

The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 13.4-RELEASE. This is the fifth release of the stable/13 branch.
A couple of followups on a recent episode of In Our Time.
Illegal drug transactions facilitated through Georgia's employee portal
I adore Nerves. I recently joined the core team. And I'll be doing my best to help people get along with this lovely way to co-mingle hardware and massively concurrent reliable software.
At Modular, open source is ingrained in our DNA. We firmly believe for Mojo to reach its full potential, it must be open source. We have been progressively open-sourcing more of Mojo and parts of the MAX platform, and today we’re thrilled to announce the release of the core modules from the Mojo standard library under…
In 2023, we launched an AI-powered Chief of Staff for engineering leaders—an assistant that unified information across team tools and tracked critical project developments. Within a year, we attrac...
People complain about Rust syntax. I think that most of the time when people think they have an issue with Rust's syntax, they actually object to Rust's semantics. In this slightly whimsical post, I'll try to disentangle the two.
A new analysis of mummified brains pushes back the timeline for the globalization of coca
I've seen a couple of recent posts where the writer mentioned asking LLMs to do something with a certain probability or a certain percentage of the time. There is a particular example that stuck in my mind which I've since lost the link to (If you're the author, please get in touch so I can link through to you): The…
About a week ago, my home Internet (AT&T Fiber) went from the ~1 Gbps I pay for down to about 100 Mbps (see how I monitor my home Internet with a Pi). It wasn't too inconvenient, and I considered waiting it out to see if the speed recovered at some point, because latency was fine. But as you can see around 7/7 on that…
A month ago, I flew from London to NYC, paid $3500 for a Vision Pro headset at Apple Fifth Avenue, and flew back home. I’ve been using it every day since — here’s what I think. My background, for context: I’ve been working in AR for many years. I built...
Here’s a gem from the archive of the NY Times. One day in September 1976, NY Times food critic Mimi Sheraton and Colonel Harland Sanders stopped into a Manhatta
FastAPI, FastHTML, Next.js, SvelteKit, and thoughts on how coding assistants influence builders' choices.
Go 1.23 added Iterators, so lets build a js like streaming api
Cinder is part of a growing list of US-based tech companies that encounter engineering applicants who are actually suspected North Korean nationals. Here's what we're doing about it.
The following guest post from humanities scholar Katie Livingston is part of our Vanishing Culture series, highlighting the power and importance of preservation in our digital age. My Grann’s edition of The Grady County Extension Homemaker Council’s cookbook Down Home Cookin’ is missing its front and back cover. Once…
Spam on GitHub is getting out of control and affecting 10,000's of users daily. GitHub is seemly doing nothing about it, here is the proof.
There's no official support for system-versioned tables in Postgres yet, and the temporal extensions aren't supported on Azure/AWS/GCP. Let's implement it ourselves with 3 triggers and an index.
