Recently, we had a discussion in our team about undefined behaviour (UB) in C. For those unfamiliar: We say that a program has undefined behaviour when we write code where the language specification doesn't define what should happen during execution. That means compilers can do whatever they like if they encounter…
We explore how to build local-first sync on top of simple file storage
An accelerated FAST feature detector for the ESP32-S3 leveraging 128-bit SIMD instructions, achieving ~2x the performance of the reference implementation.
How A. W. Jones improvised his way to an investment style and structure that has persisted till today.
I gave a talk about accessing Large Language Models from the command-line last week as part of the Mastering LLMs: A Conference For Developers & Data Scientists six week long …
Earlier quite a few iDOS users and supporters reached out to me to let me know about the recent AppStore policy change (Thanks, EU). In light of this, I decided to resubmit iDOS. However, it looks like Apple has blacklisted iDOS 2, preventing me from even requesting a review under that title, and I had to submit under…
A journey into Kindle A.I. slop hell with Leah Beckmann
Stealing another KakaoTalk user’s chat messages with a simple 1-click exploit.
In this post, I talk about pleasant but seemingly minor features in personal sites
This article is going to show you how to convert your (existing) wired doorbell (also works for battery-powered chimes) into a smart, WiFi-enabled, doorbell. The essential components needed sets you back about $2, yes, that is correct, just two bucks. No soldering is required and you don’t
A Kindle integration was a natural extension to my feed reader. I had to learn a couple of things to get it working, so it seemed interesting to document the implementation process.
Resilient sync for local-first apps by using existing technologies such as file systems
(I've been editing this post on and off for almost a year. I'm not really happy with it, but I suspect I never will be.)
Update: I have created an awesome-minisforum-v3 GitHub repository to list information for Minisforum V3 users, including some workarounds for the issues mentioned in this review. Quest for the Ideal
To use the Montreal subway (the Métro), you tap a paper ticket against the turnstile and it opens. The ticket works through a system called ...
No, I’ve not gone to the click-baiters (“10 tips that will change your life today!!!”), but I chose to limit myself to just 10 so that I don’t pull what is considered a R…
In our previous post, we introduced how to utilize Discrete Event Simulation (DES) in PicoLisp. Now, let's explore another application: a railroad model…
Let me set the right expectations first. This bug I found is actually not that complicated, it's very straightforward once you see what's going on. But I still think the process it took me to uncover this bug could be interesting. It's also kind of interesting that a simple bug stayed undiscovered for so long. I will…
llama.ttf is a font file which is also a large language model and an inference engine for that model.
Mobile before iOS and Android
Wild ramblings, raport from the field about choosing Vector Database for a particular project and a little bit of a rant about the current state of AI and how it's perceived, why human brains are a wonder of nature, and why it's far from 'thinking' and 'consciousness'.
It’s more than rails!
A major caveat in tools like sudo and doas for that matter is that they rely on setuid binaries and privilege escalation in order to run commands as root.
Spotify's relationship to artists can be kind of confusing. On the one hand, they pay a laughably low per-stream rate, as in homeopathic residues of a penny. On the other hand, the Big Three labels get a fortune from Spotify. And on the other other hand, it makes sense that the rate for a stream heard by one person…
Neural radiance fields provide state-of-the-art view synthesis quality but tend to be slow to render. One reason is that they make use of volume rendering, thus requiring many samples (and model queries) per ray at render time. Although this representation is flexible and easy to optimize, most real-world objects can…
Not much is known about Benjamin Thorpe (1782-1870), yet he was one of the first scholars to publish voluminous editions and translations of Old English texts. This blog provides an overview of Tho…
I was talking with someone today that really really wanted the sqrtps to be used in some code they were writing. And because of a quirk with clang (still there as of clang 18.1.0), if you happened to use -ffast-math clang would butcher the use of the intrinsic. So for the code: __m128 test(const __m128 vec) { return…
Acknowledgements First, I would like to acknowledge my friends and kind internet strangers who helped me with this post. This post heavily adapts from ...
