Who out there would find a Computer Architecture blog or podcast interesting? What if I arranged to do one in collaboration with folks like @AMD, @Arm, @intelnews, @risc_v?
Jon Masters 🏴‍☠️@jonmasters

On some level I agree. But on another I don't. Many friends have entered software engineering without formally studying it, but they're *very* smart women and men who could easily understand this, if it was ever made accessible. I intend to make it more accessible to everyone.

@nearyd @BBCNews @NPR Yeah, used to be. But in the same way that I wouldn’t want a correspondent to talk confidently about MS-DOS 6.22 running on a PC as a mainstream computing platform in 2026, I also would expect them to note the passage of time on air conditioning too 😉

The @BBCNews has a piece on @NPR right now about air conditioning and the different perspectives of Americans and Europeans. The correspondent is confidently saying (and confidently wrong) that AC uses CFCs. It does not. This was phased out decades ago under the Montreal Protocol

@IanJohnBuckley Sure. I mean, it’s an almost free extra valve but better exclude it! I get the energy argument, but it’s an opportunity to incentivize solar installation in that case

@jonmasters I read this week somewhere (so internet caveats) that UK grants for converting legacy systems to heat pump explicitly require that heat pump can not be used in cooling configuration….go figure…

@bexcran @BBCNews @NPR I will accept that unlike most Americans I not only have air conditioning but have studied the properties of the refrigerants used in my home system since I consider this table stakes to owning any system

Anyway. The entire world’s knowledge is at your fingertips. If you’re going to blah blah on the radio about something, do 5 minutes of research beforehand about modern refrigerants and their impact 👍

Brits don’t have AC because they don’t have AC. It wasn’t needed forever. Even now, much of the year there’s little point. That being said, why in the heck wouldn’t you choose to have it if you were installing an electric heatpump (to offset gas etc.)? It’s basically built-in 😉

@JamesDSneed I like the context these AIs provide on purchasing advice too. If I ask about anything for the house, it starts with a summary about the nature of the firmware and the compatibility with Home Assistant, correctly guessing those are important purchasing criteria for me

Talking to AI about zone panel config for HVAC while it knows your real interests: “Closest analogy from your world: the thermostat is setting a max P-state, and the governor does its own DVFS underneath it.”

Fuck it, we’re doing five tiers.
MTS@MTSlive

SITUATION EXPLAINED: Why is GPT 5.6's three-tier strategy the smartest move in the model release? We asked @MatthewBerman, co-founder and CEO of Forward Future. "A lot of people have been talking about model routing lately. I think the strategy of putting out three flavors, three sizes of these models of 5.6 was incredibly smart." "You don't have to go cross-model family anymore. You can just stick with GPT models, plan with Sol, delegate to Terra, maybe deploy with Luna. It's a very smart strategy, and the pricing is aggressive." @theojaffee: "Sol is 5/30. Terra is 2.5/15, so half the price of Sol. And then Luna is 1/6, so a fifth the price of Sol. For a dollar per million input, six dollars per million output tokens, you get a much better AgentSLAS exam score than Fable." @MatthewBerman: "That's kinda the same strategy that Zuck and co. are taking. And Grok 4.5, Composer 2.5. All of these non-absolute frontier labs are putting out workhorse models as their strategy to try to catch up."

@FlorianWoh @OpenHWFdn @risc_v @bilalzafar Great! Mine’s been on preorder for months and still waiting for it to ship. I guess soon! (of course I closely monitor everything going on with every other architecture, I have one of the latest RVA23 platforms from SpacemiT on preorder etc, but then I have POWER9 hw too)

Prof. Matsuoka analyzed how four forces will restructure the AI ​​industry over 2026–2030: the DRAM/HBM price surge; the arrival of frontier-capable open models; rapid inference-efficiency gains and the entry of Meta and xAI into the compute-resale market arxiv.org/pdf/2607.07207

The teams I work with at NVIDIA largely do not ask coding questions anymore. When I was hired 9 years ago, all of my interview questions were about concurrency, not reversing a linked list.
