A while back I wrote an implementation of SM-2, the algorithm used by Anki to schedule flashcard reviews. While reading up on it I heard about FSRS, a new algorithm that is slated to replace SM-2 as Anki’s default scheduler. The pitch for FSRS is efficiency: 30% less review time for isoretention compared to SM-2. So...

USB-C ports that support Thunderbolt 3 differ between models, and those on the same Mac may not all be the same. This article explains what each can and can’t do. USB4 support USB-C+Thunderbolt 3 ports on Intel Macs are run by Intel chips that don’t support USB4 connections, while those on all Apple silicon Macs rel...

© Laurenz Albe 2024 During a training session on tuning autovacuum, a participant asked me,“Why is autovacuum_vacuum_scale_factor set to 0.2?”Rather than replying with a guess or a wisecrack (“Because that's the way somebody implemented it!” or “If you don't like it, submit a patch!”), I decided to use the opportuni...

A while ago, I happened to see a tweet from @dhh where he mistyped a Git command as git pushy and was surprised to notice that Git figured out that he probably meant git push and then gave him 0.1 seconds to verify if that's what he wanted to run before it ran it anyways.100 milliseconds?As David is a semi-professio...

Sun, Jan 12, 2025 I want to generate the subtitles for the Normal PeopleTV series in my laptop using LLM. After searching a bit, whisper from OpenAI was a proper fit. The first step is to extract the audio from the video file using ffmpeg and store it separately. ffmpeg -i /Users/kracekumar/Movies/TV/Normal.People.S...

We present a novel approach to context-free grammar parsing that is based on generating a sequence of grammars called derivative grammars from a given context-free grammar and input string. The generation of the derivative grammars is described by a few simple inference rules. We present an O(n2) space and O(n3) tim...

I'll share a mathematical approach to discounting the loop overhead when looping over a piece of code in order to measure how long it takes (as compared to some alternative piece of code). This might be a well-known approach, and there might be better methods, but it is nevertheless a method I independently came up ...
