Oh that makes a lot of sense. That actually makes a nice image for the train-wreck of cascading particle collisions that happens. Air is dense enough its impossible to move that fast thru it. But the particle hits the air moving that fast.

With a 1982 commodore 64, a tight polling loop could detect a button press within 7 microseconds of its occurence. An onscreen change could be displayed with another 5 microseconds (more if the display happened to be in horizontal or verti

Because some of the best math libraries are written in Fortran. Seriously lots of heavy duty scientific code was written in Fortran in the 1970s and is still underpinning applications today. In many cases there is no equivalent alternative.

The crazy thing about the process is even when there is a strong suspicion the chemical is NOT safe companies still were allowed to sell products with it for decades, until it was PROVEN to be not safe. One can imagine a system where it was

I expect lasers as the military defense innovation to follow, more than the widespread deployment of nets. There are demonstration units out there that can potshot mosquitos out of a farm field. Power that up and you've got something t

The article postulates that something changed from the Covid pandemic to cause the divergence. I think a more plausible alternate explanation is the cause is a concerted and successful effort to spread misinformation for political reasons.

Is there any reliable way of recognizing GAN-generated photos? It seems the suupposed authors here probably have AI faked photos as well.

Part of the "pessimism seems high" story is there is a very intentional concerted effort by republican politicians and their media backers to sow the feeling of pessimism. This is not negligable!

The C4 compiler [ https://github.com/rswier/c4 ] is a self-hosting compiler for a subset of the C programming language that produces executable x86 code. You can understand and audit this code in a couple of hours (its 5

The C programming language was often thought of as "portable assembler" code. It abstracted over an architecture of machines similar to the PDP-11. As it turned out, for many years this was close enough to the mainstream computer

I have and ride a onewheel but never skateboarded. It really is a different balance; one-wheeling hasn't helped me a bit for skateboarding skills either. My take on the safety bit is I would never ride the one-wheel at the top speed th

The alternative is government standards. You have power outlets you can interchangeably plug different appliances into. Why? Standards. Let there be a standard for color-controllable light sources that ensures interoperability of components

Thanks! Your newer research is pretty convincing. Makes me a bit sad: I really like the 'plastic tree' analogy. Ah, well.

The way to understand the origin of fossil fuel deposits is that hundreds of millions of years ago trees were made of plastic. Thats not quite literally true but it gives the right sense. In the Carboniferous period trees grew abundently b

The same stores sell completely ineffective homeopathic "medicines" alongside real medicines already. There are no signs. Its already up to the consumer to determine what may or may not actually work at the pharmacy.

Electricity markets give widely varying prices thru the day. Even just thinking competition betweeen clean energy sources, in early evening peak hours geothermal wouldn't be competing with PV directly but rather PV via battery storage.

The big question with fossil-fuel driven climate change is, who is going to own the oil and coal that gets left in the ground? If we are going to avoid climate catastrophe, large amounts of fossil carbon needs to be left buried. Someone cla

you can't move application launch logic to install time, it's inherently a launch time process - loading resources into memory, setting up runtime data structures, etc That is exactly what I want to do. Imagine your system had t

Yeah, agree: the really big gain would come from moving init logic from load time to install time.

Running multiple instances: launch+fork with copy-on-write semantics? Re: ASLR, yeah I think you would lose most of that mitigation. Would it be worth it to make launching even the biggest programs instantaneous? The usability upside could
