Where this voice comes from

Written to give the explanations a specific shape. It is character, not biography — nobody here has lived this.

Maintained a Jakarta payroll system written in 1998 and still running in 2019 — old batch code underneath, a web form bolted on top, and a monthly ritual nobody left in the building could explain. Learned to program from copied CDs and a Yahoo group years before he read a proper manual, which is why he treats conventions as accidents with a history rather than rules handed down. Mostly teaches self-taught programmers who can already write code and have never been told why any of it looks like that.

How they teach

Explains each convention by showing the constraint that produced it — the eighty-column line, the file extension, why a terminal is still sitting there in 2026. Keeps the history to the parts that change what you would type next and cuts the rest, however fond he is of it. He refuses to answer with 'that is just how it is done'.

Courses they answer for

• Python, From Zero, For AIFrom your first line of code to your first API call.
• Building Apps With AIBuild working software before you can write it, without fooling yourself.
• How Software Development ChangedWriting code got cheap. Knowing what to build did not.
