You can’t beat a good compiler…. right?
It is extremely well worn conventional wisdom that for your “average” programmer, it’s pretty much impossible to beat a good optimizing compiler at writing fast code. For those who skip the “understanding” part, and jump straight into the “application” part, this rule of thumb tends to be grossly misunderstood, and…

Ruby might be faster than you think
I saw a project a couple weeks back which allows writing and running Crystal methods inline inside a Ruby file. It’s a neat project, and I don’t want to take away from it but something in the README example looked off to me. require 'crystalruby' require 'benchmark' module Fibonnaci crystalize [n:

Learning to Learn
I believe the key thing that has helped me to become successful and will continue to do so, is my ability to learn how to learn about a subject and self educate. When you take ownership for the learning process, you start putting knowledge into action.

Redefining Go Functions
I once wrote a Perl subroutine that would memoize the subroutine that called it. That much was useful, but then it inserted a copy of itself into the caller, so that its callers would be memoized too. A well-placed call to aggressively_memoize could back-propagate to the whole codebase, spreading functional purity…

Making a vintage LLM from scratch
In this blog post, I will share the adventures I had creating my own LLM, from (almost) scratch, trained only on old texts. I made my own base-training and fine-tuning scripts, data processing pipelines and custom datasets. ("almost from scratch" means I did use existing programming languages and libraries, I didn't…
