The latest blog posts to take off on Hacker News. 3,433 posts.
Throughout the last year I’ve written in detail about the rot in tech — the spuriousness of charlatans looking to accumulate money and power, the desperation of the most powerful executives to maintain control and rapacious growth, and the speciousness of the latest hype cycle — but at the end of
More than a million domain names — including many registered by Fortune 100 firms and brand protection companies — are vulnerable to takeover by cybercriminals thanks to authentication weaknesses at a number of large web hosting providers and domain registrars, new research finds.
So, let's say that a security vendor, we'll call them ClownStrike, accidentally takes down most of their Windows install base with a poorly tested content update. Rough day at the office, huh? There are lots of things you could say about this, lots of reasons it happens this way, lots of people to blame and not to…
Here’s a little “fake stats in the wild” gem that I think you and your followers will find at the least somewhat amusing.
I will never stop dying on this hill
Regulation-induced monocultures meet unfortunate but explicable engineering decisions.
Go has good support for calling into assembly, and a lot of the fast cryptographic code in the stdlib is carefully optimized assembly, bringing speedups of over 20 times.
We show that a system that has only GNU's find and mkdir commands is Turing-complete.
One of Go's advantages is being able to produce statically-linked binaries [1] . This doesn't mean that Go always produces such binaries by default, however; in some scenarios it requires extra work to make this happen. Specifics here are OS-dependent; here we focus on Unix systems.
I think I should blog more about random troubleshooting sessions, if nothing else it will remind me what steps I took when it inevitably happens again!
This is basically a compilation of the lecture notes I wrote when teaching 36-401, Modern Regression, in fall 2015 . I offer it here on the chance that it might be of interest to those learning, or teaching, linear regression. There's no shortage of resources on that, but I have tried to present the subject as though…
GC within a function doesn't work how I expected
Yesterday on Twitter the inimitable Morten Just posted a preview of a tool he’s created that wrap ffmpeg to allow movies, such screen recordings but pretty m...
(or at least work better)
Was the Internet Created for Nuclear War?
I became interested in implementing programming languages a few years ago and discovered [Crafting Interpreters](https://craftinginterpreters.com/) by Bob Nystrom. At the time, I had experience with Rust and decided to use it to follow the book. Albeit, being a noob, I managed to implement a fully functional bytecode…
Silently sends up to 255 bytes of the client's heap to the server . The server must support NPN , and the heap data is encrypted in transit.
Recently, GDM released a great paper titled, Scaling Exponents Across Parameterizations and Optimizers, in which they conduct over 10,000 LLM training runs to obtain optimal hyperparameters under different regimes. After reading it (it was great), I wanted to test my understanding of the paper by tallying up all…
Zig’s reflection combined with Zig’s ability to import C header files means Zig can be used for C macro reflection.
Exploring memory-efficient techniques for LLMs
David Kopec's blog.
Vercel has a decent entry level analytics product which I cannot afford so I am going to build my own.
Just after midnight Eastern Time on July 19, 2024, the enterprise cybersecurity company CrowdStrike YOLOed a software update to millions of Windows machines. Or as they put it:
I recently went down a very deep rabbit hole to understand why, some months, Cloudflare was charging us 3x what we were expecting for their Cloudflare Images service. I’m posting this write-up because back then, a quick search didn’t turn anything up; and Cloudflare support has totally ghosted us for more than 8…
A free survey course on LLMs, taught by practitioners.
Last time, I explored the inside of the Super Nintendo cartridges . Today I am going through its video system.
How bounded higher-kinded polymorphism arises in practice, and how to express it in OCaml, in several different ways. Some ways are rather concise -- but less widely known.
A couple of years ago I wrote about tolower() in bulk at speed using SWAR tricks . A couple of days ago I was interested by Olivier Giniaux’s article about unsafe read beyond of death , an optimization for handling small strings with SIMD instructions, for a fast hash function written in Rust.
