https://jaf.run/ jaf.run ยท from another perspective Essays by Jafran Hasan. 2026-04-22T00:00:00.000Z Jafran Hasanmail@jaf.run https://jaf.run/en/articles/the-shape-of-a-good-cli The shape of a good CLI 2026-04-22T00:00:00.000Z 2026-04-22T00:00:00.000Z Most CLIs are accidents. They evolve from a script someone wrote on a Tuesday. The good ones share a small set of choices made early: about defaults, verbs, and how silence should feel. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/static-types-for-config-files Static types for config files (and why your IDE hates you) 2026-04-03T00:00:00.000Z 2026-04-03T00:00:00.000Z A YAML file is a typed object whose type is hidden in a wiki page from 2019. We can do better, and the fix is mostly about where the schema lives, not what language it's in. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/notes-on-rebuilding-my-feed-reader Notes on rebuilding my feed reader (again) 2026-03-18T00:00:00.000Z 2026-03-18T00:00:00.000Z Third rewrite. Same UI, different engine. I keep arriving at the same shape: a list, a column, a single quiet keystroke for 'next'.

What broke, what surprised me, what I'd skip next time. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/on-believing-things-you-cannot-prove On believing things you cannot prove 2026-02-09T00:00:00.000Z 2026-02-09T00:00:00.000Z Engineers are taught to distrust anything that can't be falsified. Faith, religious or otherwise, asks us to hold beliefs that resist that test. I've come to think both habits live in the same person, and they should. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/ssh-as-a-protocol-not-a-shell SSH as a protocol, not a shell 2026-01-21T00:00:00.000Z 2026-01-21T00:00:00.000Z If you only use SSH to get a terminal, you're missing the more interesting half. A tour of port forwards, multiplexing, and using SSH as glue.

I went looking for silence and found a quiet conversation about attention instead. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/a-year-of-running-from-a-laptop A year of running everything from a laptop 2025-12-04T00:00:00.000Z 2025-12-04T00:00:00.000Z No cloud. No VPS. A loud fan and a domain name. What I learned about uptime, electricity, and the difference between a hobby and a habit. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/stoicism-is-not-a-personality Stoicism is not a personality 2025-11-12T00:00:00.000Z 2025-11-12T00:00:00.000Z The version of Stoicism that gets sold online is mostly aesthetic. The actual texts are stranger, quieter, and far more interested in other people than the LinkedIn version lets on. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/the-quiet-keyboard-shortcut The quiet keyboard shortcut 2025-10-28T00:00:00.000Z 2025-10-28T00:00:00.000Z The best shortcut in any app I use is the one that does nothing. It just dismisses things. Esc, with care. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/two-weeks-in-a-japanese-cafe Two weeks of writing from a kissaten 2025-09-15T00:00:00.000Z 2025-09-15T00:00:00.000Z I spent fourteen mornings in the same coffee shop in Kanazawa, ordering the same thing, in a language I barely speak. Here's what happens to a draft when you remove every variable but the page. Jafran Hasanmail@jaf.run https://jaf.run/en/articles/a-tiny-language-for-todos A tiny language for todos 2025-08-22T00:00:00.000Z 2025-08-22T00:00:00.000Z I built a parser for the way I already write todos in plain text. Tags, dates, priorities, and a single character for 'maybe'. Jafran Hasanmail@jaf.run
