almostnormal··on Electric school buses more than doubled in USA from March 2022 to June 2023
Other busses are used the whole day, which seems diffucult to do on batteries (stops too short to charge). School busses, however, are used twice per day, which seems perfect for battery powered busses.

If any bus works on batteries, it's a school bus.

almostnormal··on Ask HN: What low risk passive income makes you feel secure?
> What passive income (pre tax) makes you comfortable, if you were to put all your current net worth ( Which excludes the house you live in) in a very low risk instrument [...]

All net worth in one single instrument, no matter how low risk, would not make me feel comfortable.

Easy/hard switch at the top doesn't seem to do anything?

Maybe instead of hints for 4 bit summarize them to combined hints for the full bytes in hard-mode?

almostnormal··on 4B If Statements
The first part of GWBasic I learned by asking someone for help was "chain", after having taught myself print, input, if, and goto from the documentation.
almostnormal··on Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?
Except that not every hour is the same. Flying straight and level following a GPS track with no relevant weather or traffic anywhere near accumulates a different kind of experience than other kinds of situations (bad weather, complex airspace, other traffic, ...).

Number of landings is probably more relevant for survival.

almostnormal··on American Airlines demonstrated contrail-reducing technology
That strategy seems to be useful only for flights in the afternoon/evening (depending on how long the contrails persist) and night to avoid trapping radiation back to space. But during the day contrails should reflect back to the sun. Optimize routing to create them (only early during the day, so they disappear before it gets dark).
almostnormal··on Misra C++:2023
With strict rules anyone can write software that does not instantly fail horribly (e.g., if pointers are not allowed, there won't be a bad dereference (but that's not even in misra)). That helps outsourcing to the lowest bidder.
almostnormal··on Possible to detect an industrial civilization in geological record? (2018)
Mirror on the moon.
almostnormal··on McDonald's ice cream machine hackers say they found 'smoking gun'
Isn't the cost of the ingredients some $0.2 (I have no idea, just estimating by the taste), so that machine is printing money when working?

It's surprising they cannot build a machine that does not break that easily.

almostnormal··on Ask HN: Can we do better than Git for version control?
Something that is better should be able to track moves, not just store state. Moves of files and even partial content moved within (text) files. Unfortunately, that needs a tight coupling to the editor, so I doubt that's going to happen.
almostnormal··on Three things that LLMs have made us rethink
Humans are easily convinced (fooled) by clever use of language. Politics, tests, interviews, everything.

There has always been a difference between actual understanding and just great presentation.

LLMs are so far ahead in their use of language that given a complete lack of understanding they are more capable than humans to fool the listener. But there's nothing substantially new, some people have mastered that skill, too.

almostnormal··on "Heaving oscillators" use wave power to extend shipping range
> Let's assume the weight is 30m wide, 10m tall, 30m long, and full of water. That's 900000kg.

I think that's missing one order of magnitude: 30m * 30m * 10m = 9,000 m^3; at a density of 1t/m^3 that's 9,000,000 kg.

almostnormal··on Tinnitus linked to undetected auditory nerve damage
Click is from pressure gradient when opening/tightening the eustachian tube. If I switch to open I can hear myself breathing.

Partially covering the outer ear makes the flow of blood audible.

That's not tinnitus-related.

almostnormal··on Hyundai Uni Wheel electric drive system could revolutionize EV design
Manufacturers often buy gearboxes from suppliers instead of producing them. Hyundai does have Hyundai Transys as separate company for transmissions, and they would likely be happy to sell complete devices, not just licenses.

almostnormal··on The weirdest bug I've seen yet
> [...] and therefore probably Microsoft [...]

Where it will go through teams, outlook/exchange, or O365.

Not leaking data is no longer as easy as it used to be. Just some forms are more accepted than others.

almostnormal··on Proposal on implementing permanent time zones in the European Union
> Honestly I would prefer to go even further - UTC for the entire planet, no offsets.

The use of "tomorrow" and "yesterday" will be confusing in parts of the world where at 24/00 o'clock it isn't night. Convincing people will be difficult.

But for just the the EU it would work nicely.

almostnormal··on CSAR: European Parliament rejects mass scanning of private messages
> As shown by recent wiretappings, politicians have the most to lose if they give their chat logs away to a smaller, unelected group of people.

Surely the creators of the policy will not forget to exclude themselves from being affected.

almostnormal··on IKEA sensors for doors and windows, motion, water leaks
> It's also a bit weird that washing machines don't come with water leak sensors but I guess manufacturers don't want to highlight the possibility of their products causing water damage.

A sensor can alert someone but doesn't stop the water. There are alternatives:

1) An electric valve directly at the tap that the machine actuates when it needs water. Usually comes with hose-in-hose to capture water from a ruptured line and detect and stop releasing water.

2) Quantity limiting devices to limit the quantity that can be used contiguously, and reset when the flow stops. Set to the maximum needed by the machine. Should there be any leak, the possible damage is limited. No electricity needed.

almostnormal··on Noyb files GDPR complaint against Meta over "Pay or Okay"
Probably there is more: It is also useful to show ads to non-paying friends, valuable to sell to data brokers, and made available to 3-letter agencies.

For an analysis of the graph between users, does a link between two users break when one is paying or both? Don't they even track graphs beyond non-user, e.g., same non-user phone number in two user address books?

> EGR is responsible for recirculating exhaust gases back into the intake primarily to increase efficiency, but a nice side effect is that it heats up the engine a lot quicker.

Efficiency does not need EGR. EGR only helps to keep NOX down when running efficiently. In some (many) vehicles EGR is disabled at cold temperatures.

almostnormal··on The big TDD misunderstanding (2022)
> Makes me wonder if there is a school of testing that deliberately tries to restrict meaningful assertions to higher level tests, so that their "exercise" part is cheaper to maintain?

That's a nice summary of the effect I observe in the bubble I work in, but I'm sure it is not deliberate but Hanlon's razor applies.

With sufficient freedom for interpretation it is what the maturity model of choice requires.

almostnormal··on Why aren't motherboards mostly USB-C by now? (2021)
Or standardizing USB-XLR.

People would complain about the price of the cables, the size of the cables, and the size of the devices.

Small is fragile, and fragile should be replaceable.

almostnormal··on The big TDD misunderstanding (2022)
Part of the problem is caused by all sides using the same terms but with a different meaning.

> You just don’t know if your system works as a whole, even though each line is tested.

... even though each line has been executed.

One test per line is strongly supported by tools calculating coverage and calling that "tested".

A test for one specific line is rarely possible. It may be missing some required behavior that hasn't been challanged by any test, or it may be inconsistent with other parts of the code.

A good start would be to stop calling something just executed "tested".

almostnormal··on Rolls-royce confirms all of its current engines can run on 100 percent SAF
Anything. Even the smart (the small two-seater) was available with a Diesel engine (when those still had combustion engines).
almostnormal··on Casino-like apps have drained people of millions
The result is the same, but the path differs. I doubt addiction appears out of nowhere. First some kind of reason for an activity is needed. Real casino - chance to win, big fish casino - social status within the club. In both cases the addiction seems to be self-reinforcing: A chance to win all the lost money back vs. not wanting to lose the status that was so expensive to reach.

Individuals are intelligent, but groups of people create peer pressure, and individuals become capable of the most stupid behavior imaginable. Just wasting money isn't even the most extreme form.
