Coming Home to Vim

I'm a programmer. I work with text files for 6-12 hours every weekday so I care about the text editor I use. If switching to a different editor can increase my efficiency by even 10% it would save a good chunk of my time and let me get back to making cool things.

I kind of killed Mercurial at Mozilla

Did you hear the news? Firefox development is moving from Mercurial to Git . While the decision is far from being mine, and I was barely involved in the small incremental changes that ultimately led to this decision, I feel I have to take at least some responsibility. And if you are one of those who would rather use…

The Elegance of the ASCII Table

ASCII, a standard whose legacy defines to this day how most of the letters and numbers in your computer get encoded into ones and zeroes, is elegant and beautiful. Via lessons in computer history, punched tape, and typewriters, I'd love to share some of its logic with you.

LLM Powered Autonomous Agents

Building agents with LLM (large language model) as its core controller is a cool concept. Several proof-of-concepts demos, such as AutoGPT, GPT-Engineer and BabyAGI, serve as inspiring examples. The potentiality of LLM extends beyond generating well-written copies, stories, essays and programs; it can be framed as a…

One year ago I've published a post about reasons why our team chose Vue.js over React for our qwintry.com project rewrite. I've made some predictions back then: I expect Vue to become a primary JS framework in 16-24 months if Evan You makes right steps, at least around

The curl-wget Venn diagram

In my view, wget is not a curl competitor. It is a companion tool that has a feature overlap with curl. Use the tool that does the job. Getting the job done is the key. If that means using wget instead of curl, then that is good and I don't mind. Why would I? To … Continue reading The curl-wget Venn diagram →

Lotus, a web framework for Ruby

Lotus is a complete web framework for Ruby with a strong emphasis on object oriented design and testability. If you use it, you employ less DSLs and more objects, zero monkey-patching, separation of concerns between MVC layers. Each library is designed to be small, fast and testable.

Lisp is not based on the Lambda Calculus

How do you condense a 30 minute talk in 5 minutes? Should you even try? These are the questions I struggled with when someone nudged me to register for the lightning talks. My talk was 30 minute long because I was to jump in if a last-minute incident would prevent someone to get on stage. Call me the backup speaker…

Flattening ASTs and other compiler data structures

This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.
