The languages that shaped Len Pennie
The languages that shaped Len Pennie YouTube video by Word For Word with Sophia Smith Galer

Up there with one of my favourite things I’ve ever made.

Episode 1 of Word For Word is here, and it’s with the inimitable poet Len Pennie.

An Unconventional Seating Plan Designed to Benefit Focus and Learning After years of search and experimentation, this teacher finally hit on a room layout that allowed for efficient shifting between whole class, small group, and independent work.

And have to share two @edutopia.org posts in a row because this one from @mrrablin.bsky.social is SO cool! I have never seen this seating-arrangement strategy before.

Come March, the buds on the tree's begin to burst, this #dataviz shows the timing of bud burst for different tree species across the UK. The black lines show the timing in the Spring for the years 2000 to 2025 and the blue line is the average day for that species.

Some people, when confronted with a problem, think “I know, I’ll get my LLM to use regular expressions.” Now they have three problems.

Epstein and the moral rot of US public intellectuals The disgraced sex offender was able to gather a group of scientists and thinkers around him who shared his anti-woke, anti-women and Silicon Valley techno-fascist views. But it doesn’t end with Epstei...

There hasn't been much media coverage outside the science media of the Epstein scientists. So I wrote about them here for @thenewworldmag.bsky.social. As many in science know, John Brockman was central in linking Epstein to scientific "public intellectuals".

Your #BanjoAunti is here with a special guest: Ed Helms! While filming “Ode to Mary Jo” Ed and I got to have some banjo time behind the scenes. Today we’re demonstrating the difference between clawhammer and Scruggs-style banjo.

What if functional programming could solve your toughest Domain-Driven Design challenges?

In the Domain Modeling Made Functional Workshop, @scottwlaschin.bsky.social shows how combining DDD with FP creates systems that are evolvable and business-aligned.

A little F# goes a long way.
The .NET Conf session “Smatterings of F#” is a joyful tour of pattern matching, pipelines, and the kind of expressive code that makes you rethink your next refactor.
If you’ve been F#‑curious, this replay is a treat.

SOAS's food studies centre (which runs the anthropology of food masters I fantasise about) publish videos of their incredibly interesting seminars.

If I was the commander in chief of the Imperial hegemon I would simply not dismantle the network of military and diplomatic alliances, favourable trade deals, and broad cultural paramountcy that had made my nation the most wealthy and powerful the world has ever seen.

just saying: it's possible that "I'm gonna dramatically constrict my state capacity while plotting dramatic imperial expansion, and expanding my set of internal enemies while alienating most of my foreign allies" is the beginning of a world-historical masterstroke. but also possible that it isn't

Remembering today that having your heart broken is a necessary step on the path to becoming fully human. Whichever heartbreak is your first, it’s probably critical that a state break your heart so that you can develop a political imagination. If this is your first, I’m sorry and also welcome.

Like many others, I’m missing @tinstargames.bsky.social this morning. While I can’t claim to have known Steve that well, we’ve been moving in the same online circles for, god, I have no idea how long. Gaming Outpost? Usenet?

He had a genius for wickedly clever little games. I especially love this:

The cynics think today's attack on Venezuela is staged and transactional. Maduro is allied with Putin, but in 2019 Putin offered Trump a swap: Russia cedes Venezuela and gets Ukraine. (See Fiona Hill's testimony in Trump's first impeachment trial, h/t @davetroy.com). Even Maduro may be in on it. 2/

Yes, weaving can be a bit addictive :) But playing around with drafts on weaving software is even more addictive!

A very comprehensive and precise spec

And of course the "spec" still needs to be designed to be comprehensive and precise :)

I certainly would love to move to a much higher level "contract language" that generates code. but I'm not feeling like this is something new and radical. What am I missing?

What Is Software Design? by Jack W. Reeves - developer.*, Developer Dot Star

Seriously, I'm not sure this view is different from the "programming is fundamentally a design activity" philosophy from 1992?
www.developerdotstar.com/mag/articles...
The "code" is immutable but you still have to deal with mutating the "spec" with each feature/bug fix.

> "If a component can be regenerated from spec, understanding its implementation is optional. You need to understand the contract, the interface, the expected behavior. You don't need to understand how it achieves that behavior, because the "how" is transient."

Sounds like a compiler to me :)
