we're lucky that this happens at 360 Kelvin and not at 200 Kelvin or even lower.

I do not know what your point is.

But there are lots of cases where people fly cheap commercial drones around an airport, and that is completely unacceptable. It could easily result in a criminal charge and even prison time.

Lol, indeed.

Imagine that you have to explain to drone pilots that even a very small drone is completely unacceptable in an airport vicinity. Yes, your 0.5kg drone can seriously damage the compressor of an engine!

They switched to this internally a long time ago which basically eliminated phishing attacks against employees. There are security teams inside those megacorps that have a general objective of reducing the number of account takeovers, and non trivial resources to accomplish that. Not everything is a conspiracy.

Also, I am sure you will be able to stick to just passwords for a pretty long time while the world moves on to cryptographic authentication. I'm not being sarcastic here.

It's literally the opposite. You "must" have a cryptographic device (a dongle) that is only doing that one thing, authentication. Doesn't have a built in radio (unless for NFC, if you want it), doesn't have any microphone or camera, doesn't store any data beyond what's needed to authenticate, doesn't communicate except to authenticate - bi-directionally, so phishing is no longer a thing, or at least it's a lot harder.

It's very hard to make a privacy case against FIDO. Practically speaking it's one of the best things that happened to privacy&security since the invention of asymmetric cryptography. The deployment of this tech reduces phishing effectiveness to near zero, or in many cases literally zero.

FWIW: the gas price is about the same in Germany, which has a median yearly income of about $45k.

Yup. Converted to gallons and the US dollar in Switzerland you have to pay $9.35 for gas (CHF2.3 per liter). Yet there's no shortage of cars on the highways here.

Have you seen what happened in the finance world with respect to Russia recently? Feels to me like it is perfectly possible with the right Zeitgeist. Pretty much all the on/off ramps for Russian money are gone at the moment.

This.

I don't understand how more people are not catching up to this simple fact that central bank "digital currencies" are nothing more than a by-pass of distributed private banking (brick and mortar + online banks). It's just moving more levers closer to central authorities.

Half-joking, but yeah. "Managing the board of directors" of course means keeping the board happy, which is done by what ansible wrote. Not just directly trying to talk them out of firing the CEO.

The main job of the CEO is to manage the board of directors (i.e. the shareholders). And the main job of the board of directors is to decide when to fire the CEO.

This is exactly what YouTube does already. In fact I see no reason why Twitter couldn't spill ad money to the content (tweet) creators within the next year or two, creating a similar ecosystem. Maybe the value attributable to individual creators would be too small? Videos are quite a bit bigger than tweets (in terms of what matters most, the eyeball time), after all.

anthony_r — Fri, 04 Feb 2022 10:17:53 +0000

Because arithmetic is completely solved and boring, duh.

There was a time when it was at least a little bit interesting, and many mathematicians were actually quite good at it.

> I'm talking about having a compiler which could produce more optimal code in any given case, or most given cases

Funny coincidence, that's exactly what the vast majority of compiler code is for, with tens (or hundreds) of thousands of man-years of work spent on that.

Yeah you could optimize GCC to work really well for those problems, there's a great ROI for the "write something trivial really quickly into /dev/null" class of problems.

Let us know how this goes if you embark on this adventure.

You can create an operating system that just displays a static image within milliseconds yourself (shouldn't take you more than a few weeks), it would work even when compiled at -O0.

This is a very specific problem that lends itself to some fantastically cpu-friendly optimizations. Doing a single hash-map lookup here on the hot path would kill performance, and let's not even get started on any serious I/O (disk or network) as that would be multiple orders of magnitude slower. Not many problems are just "cat something extremely predictable into /dev/null".
