wait/arrive seems obvious to me. So I'll talk about that... As a synchronization primitive, its very useful for things like: parallel_memset(data, 0); // The 1024 threads go off and, in parallel + some efficient ma

GPUs are absurdly SMT. Like 8 threads or 10 threads (or tracked instruction pointers) per hardware instruction execution unit (for AMD, the Workgroup Processor, WGP) I have to imagine that some kind of queue or data structure would benefit

No. Keep Panagram a bit of a secret weapon. The minute Panagram becomes a metric the minute it becomes useless and we have to use something else.

Because SpaceX bought xAI/Twitter. All of the losses are from the xAI/Twitter side of the house. And Elon Musk needs a flimsy story so that no one sues him. It doesnt have to be a believable story, it just needs to be enough so th

The hallucination of messages bothers me severely. Especially with AI being deployed to ancient, difficult problems like the Herculaneum scroll. EDIT: To be clear, I'm talking about the "Written in Morse Code" example, fully

Dot Matrix are still used in outdoor / high humidity environments in USA. A lot of car shops with regular 100% humidity conditions will swear by dot matrix + tractor for feeding paper + printing. Plus, the carbon copy forms are guarant

Well sure. But Costcos model is clear to anyone who visits it. You only have to look at all the other shopping carts surrounding you to get an idea of how things work. Costco shoppers buy a lot at a time. Because Costco forces you to buy 4

The human driving to work, various activities, to the grocery store (and wherever else) isn't doing it for just one item like Amazon though. The vast majority of those Amazon packages are for one thing. When the inefficient pickup truc

Special items they can't get off Amazon, I presume? So they need to take that trip anyway. No one is driving an hour out of their way for groceries. And even the F150 truck example: if they are driving 30 miles to work, but 10 miles to

Humans are specifically incentivized to be efficient at scale. They'll tend to shop at loctions on the way home from work, or otherwise cut down on travel times because traffic sucks. I honestly can imagine that Costco is overall more

Just do what Kagi does. One older traditional search bar. A 2nd AI chat interface for people who want AI. I seriously can't believe how simple the solution is, but how much Google refuses to do it. AI search is a totally different prod

The original Intel 8051 was 4k EROM and 128B of RAM and set the world on fire with its applications. 16kB Flash and 1kB SRAM is plenty. ------- However, the analog capabilities of this thing are nearly trash. One ADC?? No comparators? No Op

Anyone using these small chips for hobbyist purposes probably should look at the more fully featured MSPM0-L line or MSPM0-G lines. Still Cortex-M0+ and in the sub $2 market... But hobbyists probably don't see much cost benefit below t

With a 12-bit singled ended ADC? That's laughable. You can't reliably measure current with this thing. I'm not seeing any voltage comparators which are really useful for most of those use cases... Now the MSPM0 series chips h

In my hobby projects, I tend to use the AVR line. Starting from ATMega328p over a decade ago, the AVR line has always had a special place in my hobby toolbox. Browsing a bit on Microchip's blog, I discovered that the a new line of chip

I don't think Iran has homing ballistic missiles. Only maybe China has those. As such, the best defense vs ballistic threats is simply moving around, if they can't home then who cares? I mean, buildings and hardened targets do car

Not new. These drones were in production in Iran since 2016 after the capture of the downed Reaper Drone in 2011. What is new is Irans willingness to use them. Which skyrocketed after a few missiles assassinated their supreme leader.

Yeah it's more of "on a hypothetical infinitely parallel computer, you'll get a big speedup'. Which is still useful if you can prove a problem is in NC. It's just not quite as strong as people make it out to be.

Regulation is not possible with today's politics. But it can become possible as soon as January 2027 politics, which is largely determined by the 2026 November election.
