I recently tried agentic coding for real. It cost $0.034 and finished in 3 minutes. It made two mistakes. In my personal human attempt, I took an hour, and made four mistakes.

Cheaper model services

I heard about GLM-5.2, and a lot of benchmarks are saying it's on …

Detect 4-leaf clovers in your pictures

A year ago, a Black man was arrested for theft. The evidence was crummy face-recognition coupled with a security guard's ID who had not seen the person, only a security tape.

A few months ago, some civil rights organizations filed a lawsuit against the Detroit Police Department for the wrongful …

I recently made SymReg. It lets you discover mathematical expressions that explain some data based on some other data.

The code used for this blog post is in this notebook.

Let's try it on a sine wave, in spite of the fact that it does not have a sine building …

Take Uncle Bob's Clean Architecture and map its correspondences with Gary Bernhardt's thin imperative shell around a functional core, and you get an understanding of how to cheaply maintain and scale software!

This is what Mr. Brandon Rhodes did. It's not every day that I find such clear insight.

I …

Updated 2020-09-03: Statement on coupling

I was recently blown away by watching some of Uncle Bob's Clean Code presentations (make sure to check out his blog). Of particular focus was his demo of Test-Driven Development, which when done right, reduces defects, development cost, and maintenance cost of software.

In …

In my review of cryptocurrencies, I mentioned that Bitcoin Cash offers "relatively less security compared to Bitcoin".

What did I mean by that?

What are the various kinds of security that a cryptocurrency offers? How to enhance them and avoid compromising them?

I will address the following questions:

I shared my previous post on Reddit, and I got some very useful feedback which pointed out the irrelevance of what I was measuring (and also a scientific paper pointing out many statistical errors in a "real" GitHub study).

So, I figured I'd measure something more relevant: bugs.

Caveats

Sadly …

I decided to review some programming languages, by comparing their popularity with their Rosetta Code implementation terseness.

I measured terseness as the average of implementations' estimated zipped code filesize.

Update 2021-01-17: After another enlightening Reddit discussion, I realized an even worse caveat of just looking at Rosetta Code snippets is …

On the surface, CDNs (Content Delivery Networks) present a great way of speeding up the loading of websites.

Without a CDN, requests take longer for users that are far away network-wise, but not a lot longer if users are near the server (perhaps on the same continent). Here are some …
