There is there there... The substance is they've created a way to fabricate a device that can make the optical frequencies they wish. That is useful: it means a designer isn't limited to frequencies that are economic to generate

Sure. Heavy industry. It's important. Maybe don't send it all to Asia because it's dirtier than software and finance.

"Azure and GCP use LM behind the scenes" As does OCI, and (relatively recently) AWS. That's a lot of votes. Use case: some legacy database VM needs to move because the host needs maintenance, the database storage (as opposed

I mean making any given VM stop on host A and appear on host B; e.g. standard Qemu/KVM: virsh migrate --live GuestName DestinationURL This is feasible when network storage is available and useful when a host needs to be draine

What is the status of supporting live migration? That's the one feature of similar systems that always gets left out. I understand why: it's not a priority for "cloud native" workloads. The world, however, has work loa

"I had no idea the US was still capable of things like that." It's more than just the US though. It's the demand from foreign customers that makes it possible. It's the careful balance between cost and capability

The F-35 case is interesting. Lockheed Martin can, given peak rates seen in 2025, produce a new F-35 approximately every 36 hours, as they fill orders for US allies arming themselves with F-35's. US pilot training facilities are brim

Last night I had a lightning strike nearby and one of two displays blanked for a second. It's behind a UPS and a good surge protector. Likely some EMI/RFI getting into the power and/or display cable of the monitor itself, t

There are a couple outfits making M.2 AI accelerators. Recently I noticed this one: DeepX DX-M1M 25 TOPS (INT8) M.2 module from Radxa[1]: https://radxa.com/products/aicore/dx-m1m If you're in the business of

It certainly looks like something that will find novel applications.

"just funny meme backed code" I laughed. That's inspired. Quite the nerd-snipe as well, based on the rapidly accumulating threads on effectiveness, probabilities and markets.

Replying to myself, because iliatoli's reply to me was [dead] so fast I couldn't reply to it directly... "The physics is mine — thirteen years of it, starting from the 2013 paper. I use AI for editing, as I use a calculator f

That's an excellent rebuttal to this common factoid. Recently I encountered a view that has me thinking. They characterized the PIO "ISA" in the RPi MCU as CISC. I wonder what you think of that. The instructions are indeed

Maybe. People are free to partake in whatever cognitive misadventures they wish. I merely cite the incontrovertible fact that Berkeley RISC predates essentially all of the modern economic history of China, and also the rise of ARM. It ca

"It is Chinese companies looking for ARM alternative" The V in RISC-V represents iteration of the ISA, over the last 46 years, most of which occurred in the US, mainly at Berkeley.

It wasn't discussed, so we're left to speculate. If I had to guess, I imagine that the .NET JIT has actual benefits: the variety of architectures has gotten enormous and JIT is likely a performance win after warmup.

SDRPlay is using Avalonia for its SDRConnect desktop UI. That's the one native application based on Avalonia I've spent significant time in. It's ok. I give it pretty high marks. There is a good deal of "lowest common

Much appreciated. Bad mouthing others hard work is not encouraged, but when I and others point out this behavior, it actually gets modded up. So yes, you should feel confident that default off is the right choice.

The NASA app is here: https://www.nasa.gov/missions/artemis-ii/arow/ It has "Distance From Earth" at 44,096 km (converted from miles...,) as opposed to 158,000 km. So yes, far off.

One workaround Microsoft has done for use-after-free is detecting when an application is prone to this and using an allocator that doesn't actually free RAM immediately. It believe that lovely bit of fun is a function of "Heap Qu
