Reading Other People's Code
I really enjoy reading other people’s code, it allows you see how others solve common problems, and sometimes even provide parables on what you shouldn’t do with yours. It also teaches the much needed skill of reading other people’s code. Now, ask yourself two questions: 1. how

Android Security Auditing: Investigating Unauthorized Screenshots
About six months ago, I discovered something on my smartphone that horrified me: I went to undelete a file in DiskDigger, and I stumbled upon a plethora of unexpected jpegs: screenshots of my activity. Screenshots that I didn’t take. Screenshots of my conversations. Screenshots of my GPS position. And screenshots of…

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.

My simple knowledge management and time tracking system
I am using a very simple system for remembering commands and procedures, and for tracking what I work on. I have two plain text files called notes.txt and worktime.txt. In the notes file, I write d…

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…
