We got to build mini versions of the first 4 languages (imperative, lisp, ML, Smalltalk) in the PL course at tufts which is now published as a textbook [1]. There used to be a prolog part that sadly got cut.

All of these are supported in pandoc markdown:

> YAML front-matter for title, theme, named styles, and dataset references.

> Fenced blocks for data/visuals: ```chart type=bar x=region y=sales.

Read manuals to learn niche software, right now I’m reading about LyX and TeXmacs (their manuals are very well written). Lots of these more niche software can always use more love and users.

There's so much wrong with this article. For starters, no one speaks Classical Chinese/Wenyanwen. Not now, not ever. It was designed for writing only, and the conciseness was to preserve bamboo (but stayed because it conveyed a sense of authority). Most importantly, modern Chinese remains challenging after all of the "westernization" events used as examples in the article, and the difficulty is not just because you get a new set of characters. On top of the writing system, you need to learn the tones, new phonemes like x, zh, q, and an entirely new vocabulary that shares very little cognates with English. And the grammar is different, with Chinese relying on much less conduction and requires much more context to understand.

Ask HN: Brian Kernighan's "Q"?

remywang — Thu, 02 Apr 2026 17:18:16 +0000

A classic DB paper [1] published in 1984 mentions a DB system called "q" written by Brian Kernighan at Bell labs, but only cites private communication by Al Aho. Does anyone have more information on the system? I couldn't find anything due to the very short name, and that "q" is also the name for the language/database by Arthur Whitney [2]

Spoiler alert: there is at least one typo in the slides.

Yes that's correct.

edit: I guess an easy fix is to append a cryptographic hash to the post ID, but yeah currently I'm assuming you trust your friends.

1. Right after initialization you'll be prompted to export the private key and store it somewhere safe, e.g. your password manager

2. You don't need to know unless you want to implement the protocol! To use (the very barebones) implementation all you need to do is fork the repo & give access, which I admit can be too much for family/friends so you might have to set it up for them (and I bet they'd be stoked to have a website of their own!)

Basic question: will this be able to run any app built for M chip? I suppose so because both a18 and the M chips are ARM?
