What happened

NVIDIA’s official Technical Blog published DynoSim: Simulating the Pareto Frontier, a May 29, 2026 post about a discrete-event simulator for the NVIDIA Dynamo LLM-serving stack.

The post starts from a practical problem: tuning an inference deployment is not a matter of maximizing a single kernel benchmark. Operators choose a model backend, tensor-parallel shape, prefill and decode layout, worker count, scheduler policy, router, KV-cache hierarchy, autoscaling thresholds, and topology. Those choices interact. A routing change that improves prefix-cache reuse can create more decode pressure on a subset of workers. A planner that reacts quickly to bursts can still fail if new workers take too long to start. Testing every plausible combination on a real cluster consumes expensive GPU time before the team even knows which configurations are worth validating.

When satellites stop inspiring wonder

Phil Plait begins with a change in perspective. As a teenager, he felt awe when he first spotted a satellite sliding across the night sky. Today the same sight fills him with dread. The difference is scale. Satellites are no longer occasional visitors overhead. Companies and governments are building constellations of thousands of spacecraft, and proposals for much larger swarms could turn low-Earth orbit into industrial infrastructure.

Techmeme surfaced this May 31, 2026 launch, and the original is NVIDIA’s announcement, NVIDIA and Microsoft Reinvent Windows PCs for the Age of Personal AI. Microsoft’s companion post is Introducing a powerful new chapter for Windows PCs, accelerated by NVIDIA RTX Spark.

The headline is that NVIDIA is entering the Windows PC processor market with RTX Spark, an Arm-based system-on-a-chip developed with MediaTek. The more consequential story is that NVIDIA and Microsoft are trying to redesign the PC around local AI agents rather than bolt a chatbot onto familiar hardware.

This summary covers The Economist’s May 9th, 2026 Science & technology article on peptideins, published under the headline Almost proteins and listed in the contents as Proteins' little cousins.

The article describes a newly named class of tiny molecules that could complicate the standard picture of how human cells work. Peptideins resemble proteins but are smaller and, in most cases, have no known function. That uncertainty is the point. They may turn out to be mostly biological noise, or some may become useful clues to disease and promising targets for cancer treatments. Giving them a name is an attempt to make researchers pay closer attention.

United flight diverted to Wisconsin after passenger’s ‘multiple attempts’ to breach cockpit, crew member says (r/news)

• Lonely_Noyaaa: Apparently he was ranting in Russian and they had to ask for a translator before takeoff. If the guy is causing issues before the wheels even leave the ground, why is he still on the plane? That feels like a massive failure by the gate agents and the crew.
• Warcraft_Fan: No specific details yet like why this man was trying to get in. He was detailed and taken in by FBI after the plane landed, no one was harmed.
• ballsmigue: There was a thread this morning on this and someone who was on the flight said it seemed like a mental breakdown.

TIL in 2018 after a Swedish mother got a tattoo of the first names of her two children at the time: her daughter Nova & her son Kevin, she realized that the artist had misspelled ‘Kevin’ as ‘Kelvin’; it read ‘Nova & Kelvin’. However, instead of correcting it, they legally changed his name to Kelvin. (r/todayilearned)

• BrentusMaximus: He’s gonna grow up and get a heart and “Morm” tattoo just for her.
• JiveChicken00: Probably cheaper that way. And definitely less painful.
• Acircusclown: He was about 2 years old, so that’s the time to change it. Imagine if he was 14 or something

• CkhN86 (Apollo Global Management): This is so funny to me because I’m retired with 70K a year in dividend payments @ 32 and traveling the world without any problems. The constant corporate career comparisons makes me never want to come back to America. I can only imagine how lowly some people may think of me in high finance/ tech for only making 70K a year if you just step outside of America that’s an insanely large amount of money

Traffic to DuckDuckGo’s proudly ‘No AI’ search page has tripled since latest Google AI search update (r/technology)

• Scoob1978: Google just sends me to Reddit all the time anyway. Switched a while back.
• ICLazeru: I’m contributing to that. Started when I noticed the Google making absolutely stupid suggestions. Not like human stupid, but like “I’m suggesting this because I don’t understand reality because I’m AI” stupid.
• FIuffyRabbit: Personally, I find ddg’s results to be lacking most of the time for technical searches.

Microsoft data suggests using AI is more expensive than hiring people (r/technology)

• nazerall: While still laying people off with record profits.
• Significant_Fill6992: and that’s with the cost still being subsidized
• Candid_Cat_5921: This story is so off point but keeps making the rounds. Microsoft isn’t giving up on AI, it’s moving from paying standard licensing fees for Claude tools, to using the same models hosted in-house. Like why would you pay 5x when you could just use the same models with your own tool (GitHub Copilot)

Huawei chairman thanks the US for export restrictions on chips, says it supercharged China’s semiconductor industry — Washington’s export controls encouraged Chinese firms to invest in R&D and build their own tech stack competing with American tech (r/technology)

• zleuth: … As we all knew it would.
• cwalk: China was always going to “supercharge” their semiconductor industry regardless of export restrictions. They are just trying to poke the US.
• SmarmySmurf: Long-term planners will always win over short-term thinkers in the end.

Quantum mechanics is one of science’s most successful theories, but success has not made it intuitive. Its predictions have survived experiment after experiment and underpin modern electronics. Yet its usual mathematical description allows particles to exist in several possible places at once until a measurement returns one definite result. Entangled particles add another puzzle: measuring one appears to determine the state of another, even across a great distance. Physicists agree that the calculations work. They still disagree about what kind of reality those calculations describe.

Techmeme surfaced this May 29, 2026 essay in its AI Dark Output cluster, and the original is SemiAnalysis’s AI Dark Output: The Visible Cost of Invisible Output.

The article asks a harder question than whether companies are spending too much on AI: what happens if the value created by AI becomes real before the economy knows how to count it?

This summary covers The Economist’s May 9th, 2026 Business column on Berkshire Hathaway and SoftBank Group, published under the headline Warren or Masa and listed in the contents as Berkshire v SoftBank.

The article presents Berkshire Hathaway and SoftBank as opposite answers to the same question: what should an investment company do when markets look unusually expensive and technology is changing unusually fast? Berkshire, built by Warren Buffett, has accumulated nearly \$400bn in cash because it cannot find enough attractive deals. SoftBank, led by Masayoshi Son, is borrowing heavily to finance a sweeping bet on artificial intelligence. One risks becoming too cautious to justify its structure. The other risks running out of money before its vision pays off.

What changed

Uber Engineering’s official blog published Modernizing Artifact Storage at Uber, a May 28, 2026 account of replacing a fragile on-premises artifact repository without moving the operational burden into every build.

Artifact storage is easy to underestimate because it often looks like a passive dependency. At Uber it sits on the critical path for builds across large monorepos and thousands of smaller repositories. Builds resolve hundreds or thousands of dependencies, and the platform stores the outputs that downstream systems consume. At that scale, an artifact repository is developer infrastructure with production-service requirements: it must remain available during failures, serve immutable bytes correctly, keep latency low, and avoid turning growth into a sequence of risky storage interventions.
