Volt is AfD for the PMC in that their main selling point is not wearing the damage of having actually governed. They appeal to people like me because they can just say things without needing to deal with political viability or implementation tradeoffs.

Don’t know, I assume that’s the minimum. I think I saw an estimate that this was only ~half off the list price, which confuses me. Maybe they’re all out in Marzahn.

Genau, some think tank just released a study saying it pencils out if we pay ~€62k per apartment.

Enteignen is predicated on compensating owners for the taking — it’s part of what makes the whole scheme so unrealistic

What is up with Berlin Marathon pacers this year? The 3:30 guy just came up behind the 3:45 guy, and I saw five 3:00 pacers spread out across twenty minutes at least.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

I've never not had an insightful interaction with Quinn Wilton. This talk, "The Graveyard of Good Ideas", is an absolute delight. I can't describe it; just listen to the first 5 mins and if it doesn't grab you…I dunno, you're just not my kind of nerd. (-: www.youtube.com/watch?v=ovlQ...

It’s only a wretched henka when rikishi you don’t like do it. When Onosato does it (on day 8 or so?) it’s a hit and shift, high level agility, Yokozuna sumo

From a note to a friend a couple of weeks ago "imo the reason text elemental is so good is because it captures the notion of something that is animate, but not conscious so much as an expression of the fundamental nature of the substance of which it is composed."

Also funnels vs development

dave @daveliepmann.com · 22/09/2026
Thinking separately about inputs (effort, coaching) versus other variables like single/multi-sport and adult-style S&C versus play-like S&C (and leaving aside the rec leagues) will lead to greatest understanding here Inputs dominate…but multi-sport and play are superior while rec is less effective

dave @daveliepmann.com · 22/09/2026
Yeah the evidence I’ve seen is pretty clear that early sport specialization and narrow S&C make for adolescent champions and early adult injured burnouts. Long-term athlete development is fairly well understood and hypercompetitiveness early on is not part of an ideal strategy.

This dovetails with other industry-specific fuckups that deserve broader recognition, like the UK Post Office scandal or Challenger. IMO these failure modes come with the complexity of modern society and we have not yet adapted to the need to explain them to the next generation.

It repeatedly surprises me how few programming literacy materials our industry+culture have produced for kids. It’s like we don’t want to pass on our tradition.

I wonder how much is proving they're not beholden to RN rather than RN being a drag. I get the sense many devs (perhaps me included) are hostile to RN based on the perceived inelegance of a shim.

LLMs make it easier to maintain two native mobile stacks than to use React Native (And the scaffolding this led Shopify to is another example of LLMs catalyzing good engineering decisions, e.g. decoupling biz logic from UI so it can run headlessly.) shopify.engineering/back-to-native
Preventing slop

It’s tempting to just point an LLM to the React Native codebase and try to one-shot the same features in native, but it doesn’t work. Even if you ask it to gather as much information as it can up front, freeze that into specs, task files, and then implement it, you end up with a huge amount of unmaintainable code that can’t be shipped.

To solve this problem, we built a system called Helix that takes a more gradual approach. It doesn't expect the first output to be correct, and builds a loop where an imperfect attempt simply cannot move forward until it becomes a good result.

The developer points Helix at a screen. Helix reads the React Native code and proposes a sequence of checkpoints (small, ordered slices of the work) that can be reviewed in minutes. Then, checkpoint by checkpoint, it builds: each one must prove its behavior with tests, match the running app in a visual review, survive two adversarial code reviewers, and get a human's nod before it's committed and the next one starts. Feedback from every review is remembered, so the loop gets more autonomous as the migration progresses.
