A Penn State engineering student's work on a century-old math problem that expands research in aerodynamics, unlocking new possibilities in wind turbine design, was recently published in Wind Energy Science.
A beginner-friendly introduction to stochastic calculus, focusing on intuition and calculus-based derivations instead of heavy probability theory formalism.
MongoDB to integrate Voyage AI's industry-leading embedding and reranking models, delivering highly accurate and relevant information retrieval to power sophisticated AI use cases NEW YORK , Feb. 24, 2025 /PRNewswire/ -- MongoDB, Inc. (NASDAQ: MDB), the leading database for modern applications,
Keep your calendar in a plain text file. Calendar.txt is versionable, supports all operating systems and easily syncs with Android mobile phone.
Teammate App had a publicly exposed database and told me to stop harassing them after I emailed them about it.
First part of a series of articles about writing a .NET Garbage Collector in C# using NativeAOT. This part sets the expectations and setups the project, dealing with the first difficulties.
A lengthy digression into the life of a saint
It is clear that ketamine at a sufficient dose & frequency can and does kill neurons through NMDA-driven excitotoxicity. However, what does a sufficient dose & frequency mean? There is a common myth that ketamine is “neurogenetic”. This is mostly false. While it does increase neurogenesis in the only two places in the…
tools, tactics, troubles along the way
What is new in Emacs 30.1? I go through every change in the NEWS file and talk about the most interesting and useful changes.
I find myself telling people that they will have to pry org-mode from my cold dead hands. Which befuddles me. Why, as an ingrate software nerd who has soured on software technology — talk about biting the hand that feeds — do I evince such strong sentiment about a software program?!
While the German economy is stagnating, Digital-Mittelstand may offer a solution.
Learning in public helps me grow as an engineer and seems to benefit others too. Here's why I should do more.
I’m setting up an old Dell box (2011-era tech). I was migrating to some new boot drives and setting up grub on them again. Got to the point of deleting the old boot entries and adding new ones, and got an error like Could not prepare boot variable: No space left on device. Weird, because there weren’t that many EFI…
I hate ads. I also hate tracking and bloat. But I didn't actually hate the latter quite enough to get rid of Disqus for comments. It was a free, good service, and you could turn off ads for the users (which I did).
Recently I encountered a bug so cute that I immediately knew that I will want to share it on my blog. It was one of those bugs that even Rust can’t save you from. It occurred in HyperQueue (HQ), a distributed task scheduler written in Rust that I work on.
The very short version: it is madness to continue transferring the running of European societies and governments to American clouds. Not only is it a terrible idea given the kind of things the “King of America” keeps saying, the legal sophistry used to justify such transfers, like the nonsense letter the Dutch cabinet…
While I’m usually blogging about triathlon, today I want to discuss one of my other hobbies, scuba diving. Diving in the UK usually requires diving in a dry suit (not always, but trust me, it’s a LOT more comfortable). One of the biggest concerns that many have is about how to deal with the bladder
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…
A quick look at the physics of conductors, insulators, and electric charges.
The first of a series of envisioned blog posts on lambda calculus, and Lisp. It’s unclear exactly where to start: there is a whole heap of interesting issues, both theoretical and in terms of concrete implementations, which tangle and interconnect. A particular application of lambda calculus is a very salient…
Around twenty years ago, people would have laughed if you told them that videogames would end up at the Smithsonian, but the Half-Life team really did want to make games that were more than just throwaway toys. The rule against cinematics — which made our jobs much harder and also ended up leaving a lot of my favorite…
There's a cute math puzzle that can be interesting to folks on very different levels:
Notes on using the Z3 constraint solver with the Clang Static Analyzer
I think it is important to have a bias for action. Like anything else, this is something you can make a habit of. Moving forward allows you to make progress. I don’t know about you, but I’ve frozen up in the past not knowing what the right path was for me. Moving forward, even the smallest possible step, helped break…
