cheerlessbog··on ITER: World's largest nuclear fusion project begins assembly
New opportunities to leak methane and we've seen it's often cheaper to ignore leaks, given the cost of it is incurred by the planet.
cheerlessbog··on The Electric Car Atop Europe’s Sales Charts Isn’t a Tesla or VW
Many live in single family homes, yes, but in the UK at least they very often have shared street parking across a pavement (a sidewalk). That is why I was thinking lampposts.
cheerlessbog··on The Electric Car Atop Europe’s Sales Charts Isn’t a Tesla or VW
The scale is daunting...running new cables for probably more than half the households in the EU. Comparable to the effort to get fiber to the home.
cheerlessbog··on The Electric Car Atop Europe’s Sales Charts Isn’t a Tesla or VW
In the US most electric cars are charged on the driveway or in the garage. Most Europeans don't have these.

I'm generalizing of course, but it's a significant difference. Most folks I know would have to run a cable across the sidewalk. Electric is only going to work if all the supermarkets and pubs etc etc have fast chargers. Or maybe they put them into lamp posts.

That's without the weight of the storage and potentially fuel cell surely.

Facebook pays more than many. Is there an ethical premium it is forced to include?
cheerlessbog··on Acorn Archimedes – A Technical Introduction (1987) [video]
Zarch blew me away at the time (in my high school computer room) as well as Conqueror, built on the same engine. Most home computer games at the time were inferior to arcade games : it was only years later that arcade games were surpassed at home, at least where I grew up in the UK.

How do carburetors work when inverting the plane?
cheerlessbog··on Teachers are ready to quit rather than put their lives at risk
Many or most of whom are social distancing or at home rather then in a room full of kids from different households. Plus very disproportionate effect on older people, a group that includes many teachers. Plus the extended effects in some cases even if you survive. Then consider how little they get paid and that there’s potentially alternatives (delay or virtual)

If a space probe discovered some vast alien structure clearly acting fulfilling some strange purpose by some opaque means... would we not usefully describe it as a machine?
cheerlessbog··on German court bans Tesla ad statements related to autonomous driving
I took my BMW i3 in for service recently and got a high end 2019 BMW SUV loaner..worth 50% more. I was expecting to be impressed. Instead I was amazed how much I disliked it - clumsy tech, loud, needs fill ups...it seems ICE tech is at a dead end. I truly wouldn't want that vehicle if it was free.
cheerlessbog··on Scientists say you can cancel the noise but keep your window open
That's with one microphone and presumably a single speaker. I wonder how well one could do with several microphones around the room and several speakers, with their relative positions known accurately and some computing power to generate the best possible reverse sound distribution.
cheerlessbog··on Disabling Google 2FA doesn't need 2FA if you're already logged in
On the topic of Google 2FA, why does it to confirm a number on my phone when I use it to authenticate? I have to pick one of three numbers. That's only a 1/3 chance of detecting that it went to the wrong phone somehow.

It's possible in some jurisdictions although as you say they can very easily be unjust.

And they have an incentive to angle for their next job. Like congress people walking into a lobbying job on the other side of the desk. Conflict of interest

Aren't retroactive laws a thing?
cheerlessbog··on Moving from TypeScript to Rust / WebAssembly
I worked on a web based editor. A library would give us a range to highlight, in 1-based coordinates. The editor control was 0-based. As you can imagine it was easy to forget to translate back and forth in one path or another. In a strongly typed language I would simply define two Range types and the compiler would eliminate the mistake. I assumed Typescript could help me in the same way but it allowed the two types to be interchanged silently because they had the same structure. Perhaps I was holding it wrong?
cheerlessbog··on 1:60 scale Boeing 777 made from manila folders
As a young adult I could absorb myself in projects like this...in recent years, mid career, it just doesn't seem to happen. I can't make myself care enough about anything to the extent it's very hard to imagine how someone could do anything like this project. Anyone have a suggestion for how to find that again? Maybe I lost the ability to focus on anything I'm not required to do to get paid. Or maybe I'm mildly depressed and don't know it...how does someone do this?
cheerlessbog··on Astronomers detect regular rhythm of radio waves, with origins unknown
I just realized what I described is not giving a lower bound.
cheerlessbog··on Astronomers detect regular rhythm of radio waves, with origins unknown
I guess the assumption is that the phenomenon starts at a point, spreads across the object sized l at c, and lasts for only a period of time t at any location. Therefore the pulse ends after l/c + t = T. By measuring T you can put an upper bound on l.

Example of this inference, from the Wikipedia on Fast Radio Bursts (but I have seen in many contexts):

> The sources are thought to be a few hundred kilometers or less in size, as the bursts last for only a few milliseconds

Does that make sense?

Thank you for that very amusing article.
cheerlessbog··on Astronomers detect regular rhythm of radio waves, with origins unknown
A broader question that puzzles me, not specific to this phenomenon. Pulse length is often used to bound the size of a source in space (it cannot be smaller than light takes to traverse the object). But it’s possible that two phenomena can be correlated without being close, if there is a delayed action (akin to setting two alarm clocks and separating them in space). How can we confidently use this as evidence of size?
cheerlessbog··on Cryengine Source Code
> the compiler will inline it if the function is only used once.

There may be other criteria, eg is the function likely to be called.

cheerlessbog··on The Great Pause Was an Economic Revolution
Inflation is too much demand chasing too little supply. If the money printing simply replaced missing demand, should we expect any inflation?
cheerlessbog··on A New Standard Deal
I appreciate when someone asks such questions as a post here saves 50 readers googling. Also it might start an interesting discussion.
