@nexta_tv they trained predominantly BVR combat last few decades and now it looks like dogfighting skills are needed...

@succintreject1 @hot_rails Its a lagging indicator, every ship thats "on time" is at the very end of the supply route down to us They left port a month ago in middle east to refineries in asia and we've had a total stop of all ships about that long from middle east to asia.

Forever grateful Tesla didn't decide to price Model Y L at $100k here in Australia. Definitely feels like a car of that category. Insane value.

@davepl1968 GST in Australia is fully distributed to the states and was supposed to replace a fistful of inefficient state-based taxes. Except the states never actually repealed a whole swag of those taxes. GST never had any connection to, nor was it a replacement for, income tax.

@elonmusk @Tesla I’d love to. I paid for it on four two cars in australia, starting almost a decade ago. When are you planning to enable it for me?

@RealGeneKim “But developers couldn't reproduce the issue because they lacked realistic production-like data.” Nonsense - the performance issue would have been obvious from a basic architecture review. No AI required for that….

I was awed and amazed while pair-programming with Hal Evans. He's a developer trained as a mechanical engineer — no CS degree, never heard of Clojure or Rich Hickey — who quickly grasped a principle that took me twenty years to learn. The result: he reduced a 4.5-hour database operation to 12 minutes using Claude Code — a 22x speedup. Hal and Sam Sutton support an application used by major grocery retailers to model costs for prepackaged meals — raw materials, processing, labor, packaging, waste — so purchasing teams can make better decisions. We were trying to solve performance problems — users reported extremely slow operations, with many queries hitting 30-second timeouts. But developers couldn't reproduce the issue because they lacked realistic production-like data. Database seeding was painfully slow: 4.5 hours. So developers rarely ran it — and the data looked like test data (e.g., "concrete pizza"). I immediately thought of the legendary performance maven Casey Muratori. His principle: before you optimize, calculate the theoretical minimum. Hal and I did the math. If we created all entities in memory and saved them in one batch, the floor was about 3 seconds. The actual time? 4.5 hours. We were orders of magnitude away. The root cause: it was impossible to separate entity creation from database insertion. Every single entity was built and immediately saved to the database, one at a time, on a single thread, on a 16-core machine. This is what Rich Hickey (the creator of Clojure) calls "complecting" — braiding together things that should be separate. The fix: we used Claude Code to separate "pure" construction from the "side-effect" of persistence. Claude created a hierarchy of entities based on foreign key dependencies: - Level 0: Entities with no foreign keys (currencies, exchange rates) - Level 1 :(suppliers, base categories) - Level 2: (products, ingredients) - Levels 3–11: Progressively more complex aggregates Once separated, we could build everything in memory (~3 seconds), then flush to the database level by level, respecting foreign key dependencies. Full seed: 10 minutes → 60 seconds (10x). Load seed: 4.5 hours → 12 minutes (22x). What's exciting: we are creating a new generation of developers who will be able to apply concepts such as pure functions vs. side effects, level-based dependencies, and decoupling construction from persistence — using AI models as architectural advisors, not just code generators. I'm so thrilled that Ben Grinnell FBCS (Board Member, Capabilities and AI) and Tom Kilcommons (AI Innovation Lead) from Newton Consulting will be presenting about this and more at EAIS San Jose. If you want to see how they're operationalizing this kind of performance engineering with AI, you need to see their talk. If you're wrestling with problems like this, you'll see concrete patterns from leaders at OpenAI, Amazon, Disney, and Netflix. Full program below — see you there!

@optiks @aaronsmith @aka_spk_ I do a 30 min lunch break and a 5 min petrol fill on the direct route. Finding a recharge station etc adds at least an extra half hour to a 7.30 hr tedious trip. When my mother dies I'll reconsider my options thank you very much.

This fun interactive tool allows you to draw circles anywhere in the world to see how many people are around you. A 3km circle around my home in Melbourne shows that I have almost 84,000 people nearby I can annoy in person with my maps! Play with the tool here: tomforth.co.uk/circlepopulati…

Fixed it 😅 ... but in all seriousness this is the ONLY thing I can fault with the Y L ! Just need Tesla to make an accessory to close the gap and problem solved.

Hi.. @ryanjaycowan One thing, if you can include in your review, how effective is it to use Model YL as a 4 seater? My concern is when seats are down - you have gap for things in boot to go between 2nd row seats..

Another #visualstudio 26 release with more AI and more bugs in basic stuff. As an example coloring in csproj files is now completely gone. Still too much spacing in solution explorer after the annoying spacings change etc. I do not know why I update... #dotnet

@IAPonomarenko LPG conversions were very popular in Australia in the 90s due to government subsidies. Then we started exporting gas internationally and the price of gas shot up. Go Australia!

We merged an early C# 15 preview feature into .NET 11 preview 3: unions. Adds union declarations (`union Pet(Cat, Dog, Bird) { ... }`) and union types (attributed with `[Union]`). They can be treated by pattern matching/switch expressions as a closed set for exhaustiveness.

Prof. Donald Knuth opened his new paper with "Shock! Shock!" Claude Opus 4.6 had just solved an open problem he'd been working on for weeks — a graph decomposition conjecture from The Art of Computer Programming. He named the paper "Claude's Cycles." 31 explorations. ~1 hour. Knuth read the output, wrote the formal proof, and closed with: "It seems I'll have to revise my opinions about generative AI one of these days." The man who wrote the bible of computer science just said that. In a paper named after an AI. Paper: cs.stanford.edu/~knuth/papers/…

@kristijan_kralj Lol, PDF is the "main bottleneck" for .net? Html to pdf, done. Doesn't even register as a blip.

Kristijan Kralj@kristijan_kralj·
PDF is the main bottleneck of modern .NET development: 1. ASP .NET Core can handle thousands of requests per second, but exporting to PDF still means installing 3 NuGet packages, reading 5 GitHub issues, and hoping fonts don't explode in production. 2. We have async/await, background jobs, cloud autoscaling, and distributed systems, yet the moment the business says "Can we just get a small PDF with a table and a logo?" the whole sprint vanishes. 3. We can model complex domains, enforce invariants, and scale systems to millions of users, but aligning a table header in a PDF still feels like dark magic. .NET devs, know your enemies.
