> Turbine is great for steady loads and terrible for cyclical loads which is what a garbage truck does all day.

Right. This would certainly apply to the mechanically coupled turbine truck prototypes from the 70's.

But if its driving a generator then you can let batteries or capacitors handle the cyclic loads of acceleration and have a computer throttle the turbine according to the overall demand.
I'm not in a hurry to move, I would like to plan and prepare for the transition once I've sat with this feeling and understand that it's real and it doesn't just pass over me.

In my experience, almost everyone out of college who I've met who claims to know calculus.
Awesome, thanks! These ballpark figures would be a great improvement to your documentation.
Here's my favorite "alternative" explanation of moiré:

sin(a) * sin(b) = 0.5 * (cos(a - b) - cos(a + b))

You may remember this formula from high school. The arguments a and b are basically frequencies. When you multiply two frequencies a and b, you will get their difference cos(a - b) and their sum cos(a + b). If two frequencies are similar (e.g. 101Hz and 100Hz) you get one very low frequency (101Hz - 100Hz = 1Hz) and the other one will be much higher number (101Hz + 100Hz = 201Hz). It's hard to see that higher frequency 201Hz, you have to come really close, but it is easy to see that low frequency, that 1Hz would manifest as 1 dark blob across entire area.

It's ultimately heating the atmosphere above them. I heard this planed had some trouble with thermal balance recently, things were getting too hot.

In seriousness, heating streets with abundant solar energy harvested nearby would be reasonable. But sunshine in winter months is not as intense, and you'd have to build, as usual, a huge battery to keep the energy for the night. (When this is solved, more problems would get solved along the way than just de-snowing streets.)
Plugin hybrids have the worst of both options as well as the best.

They have to carry with them an entire gas engine, plus large electric motors, plus a huge battery. That's a lot of mass. This makes them inefficient as gas vehicles, and less efficient as EVs.

Take a look at the Toyota Prius Prime, considered a great PHEV. It's got almost the same gas milage in combined city/highway driving as my 2012 Honda Civic (around 50 mpg). The Prius has got a slight edge. But that's combined, which presumes 45% highway and 55% city. You don't want to take that car on a road trip because once the battery is dead, you'll be needing to stop to refill the gas tank every 90 minutes. My Civic will drive 600km or more on highways, easily.

PHEVs are the best vehicle if you drive less than 60km per day, and mostly have stop-go city driving (so you can recharge on braking).
That is the claim made by AI proponents every time it fails, such as for self-driving cars - humans make mistakes too. Humans make math mistakes, but I wouldn't be satisfied with a calculator that does.

ChatGPT is a tool; it's value depends on how well I can trust it. Humans are not tools.

> experts in their field tend to inject their own biases and experiential preferences when answering questions in depth.

Another typical argument - everyone makes mistakes, therefore my mistakes aren't relevant. Everyone can do math, but there's a big difference between my math and Timothy Gowers. Everyone lies and everyone tells the truth at times, but the meaningful difference is in degree - some do it all the time, with major consequences, take no responsibility, and cause lots of harm. That's different than the person committed to integrity.

Yes, your instinct is correct, you have vastly oversimplified it in an unhelpful way. The body is not an energy equation to be balanced.

The desire to eat is driven by our hormones and these are not easily overridden by willpower. In fact, study after study shows that willpower is insufficient for most people. Hunger is produced by a complex set of factors that we do not fully understand. What we eat and how we live plays a big part in how hungry we feel.

Calories should not be counted like some fungible currency. Each food is a complex and poorly understood cocktail of organic chemistry. Food is not processed by the body in the same way or at the same speed. In the most simple sense, unprocessed whole foods digest the slowest and provide the most even energy to the body, while highly processed food is digested quickly and leaves you hungry again soon. And above all else, fiber is the most amazing thing that can be in your food to regulate your digestion and make you feel more full.

And the consumption of energy is also not a matter of willpower to go to the gym. The body regulates is caloric burn to suit its environment, again, based on a complex and poorly understood web of signals. But in simple terms, trying to eat less can also caus your body to go into a "low power mode" where you burn less energy, ultimately being counterproductive.

The magic of this drug is that is hijacks one of the important hormone pathways involved in hunger and causes you to eat less calories without a single conscious thought. If proven out as safe and effective, it could be the silver bullet in an obesity epidemic that has never had any easy solutions before.

> Modern engineering would not be possible without calculus.

Was not my question. Nearly everyone uses computers. Computers would not be possible without electronics. How many computer users work with Maxwell's Equations or have even heard of Kirchhoff's circuit laws? A very tiny percentage, undoubtedly.

The reason I asked was the Penn State professor's epiphany that no engineer among the many he asked actually used calculus.
Yea that's what I mean - the same is true in the SFBA. SJ/South Bay, Berkeley/Oakland/Richmond, the rest of Alameda county, the peninsula, etc are all quite different just like the San Fernando Valley, Inland Empire, Westside, and Orange County near LA.
> Why are they using garbage trucks to plow snow?

Perhaps because it's easy to add a connector plate and a bit of hydraulic in front of a truck and they already have them for garbage, they regularly run the on roads and their driver knowing where garbage containers are avoid some classic (at least here in UE) where the snowplowers push/launch snow everywhere not caring about anything else then keep the road clear... In a city handling snow it's even harder than in the countryside...

> But it's silly to decide to have an all-fuel fleet of garbage trucks just because they can't also be used as snowplows a few days per year that you need them.

Keeping up two fleet is not that cheap either: trucks/wheeled vehicles need to run regularly to keep their wheel well round and balanced, ICEs need to run regularly to keep the engine well lubed, starter and service batteries need to be kept charged, vehicles need to be parked somewhere (two fleets, twice the place), for ICEs you need to keep the fuel infra ready, and the amount of fuel it's not so little and so on.

IMVHO as an EV owner I doubt ALL trucks can be electric so far, simply range, charge time, battery weight are still below a practical usability levels...
This is the standard AP calculus approach although you might be familiar with non infinite series from before.
While that is true, I would highly encourage everyone to read the original EPR (Einstein Podolski Rosen) it is so amazingly clear in its writing and can be understood even by laymen.
In the event that you don't purchase any physical parts for making controllable robots, you'll find similarities in programming game physics, which really is just a simulation of the world we live in and how to propell an object around that world.

Reminds me of a thought I had after learning that it takes about 100,000 years for a photon to escape from the interior of a star. That is a long time, and the photons might be useful in conveying information throughout the structure of a star, in the same way that an electron propagates information through a brain. Extrapolate from there...

There's nothing stopping you from getting back into coding in general, that'd probably be the first step. Rivers Cuomo (of Weezer fame) can still be spotted around github issues and stuff - just as an example of someone who still codes even though it isn't their main job.
Maybe you can stay at your current Org and pivot to some more code related tasks - start small and gain familiarity and work up from there. You'd have good support from others you already know and a good "thing" to put on a resume. No experience is bad experience for someone in your position.

Best of luck to you

It wouldn't make a difference even if you were a citizen of an EU country.

My advice is to try and get a position at the EU office of a company that has a presence in the US. You can transfer on an L1 visa after 12 months.

The good news is that once you get to the US then there will be no delay in any application for permanent residency based on your country of birth. You're also eligible for the DV Lottery.
> parents can (or at least should be able to) block porn sites at the router.

Not only can parents block porn sites at the router, but they can lock down their kids browsers and even phones. Plenty of software and methods to accomplish this. That's what the state can be doing, making it easier for parents to supervise and manage their kids.

What the state is instead doing, is sneaking in a nanny and police state, under the disguise of "protecting kids". Their nanny and police state regulations affect all, not kids.

Just as easily (and arguably being more smart about it), the state could have setup a website and given free software tools for concerned parents to lockdown their kids computers and smartphones, if you really want to take it that far. Take it even further, have "certified" stores selling computer devices to be used by kids, to have this available for configuration and install for parents who want it.

The BS that Louisiana is trying to pull off, is not going to stop kids (with any lick of knowledge about VPNs), nor help facilitate better parenting. It's just the state lying and fumbling its way towards becoming more draconian and pulling off more grift.
Yes, but in the US grades are used for selection, so it seems reasonable to keep them comparable.

Since we in the EU have the Bologna system French and Italian students will come to Sweden and Swedish students go to French universities, and if some universities are just handing out As or others grade properly it will become strange.

I think it's actually useful to be able to see the people able to perform at the 10% level in hard classes. For example, suppose that a student in a less prestigious subject takes a hard class in a more prestigious subject, and performs at the top 10% level-- it seems reasonable that he should be able to show that off with a grade that is genuinely high.

Furthermore, top 10% performance is something to strive for. Top 40% performance, it's not very good. It means you've maybe understood most of the course, but it doesn't mean the ability to creatively apply the material, which top 10% in fact can.

Probably unpopular on HN but my take is that someday the police will be able to take control of a vehicle, or to force it to stop, remotely, maybe directly from their car's terminal.

Input registration number, select 'take over' or 'force stop'. Done.

A corollary is that tempering with a vehicle's control system will likely become a criminal offence.
few cities have ALL streets electrified. usually just main corridors where buses will operate.

These buses usually have some battery, but not a lot, and coming on and off the wires is often a manual procedure.
You're not wrong. I agree with you. I just see that as a better option than continuing to burn fuel in trucks that don't need it 360 days per year.

Not if “reproduce the [possibly Unicode] string verbatim” includes concatenating it with others in order to insert it into some sort of context, that will absolutely blow up if you’re not careful and unfortunate input data comes in (I hope that happens before the code enters production!).

For comments and string literals in Python code, note that Python 3 changed the default from Latin-1 to UTF-8, but you can still use -*- coding: -*- to change that. Bytes literals outside of ASCII range you’ll still have to escape. As for program input that’s possibly invalid UTF-8 but not in places you care about, you’ll need to set errors='surrogateescape' or similar explicitly (or possibly set an 8-bit encoding like Latin-1, though not if there’s a chance of UTF-8 in places you do care about).

Paths are a bit painful, yes, both because there’s nothing on Unix systems that precludes /home/alice having filenames in UTF-8 and /home/boris in KOI8-R, and because NT paths are not byte sequences at all (they are WCHAR, that is 16-byte-number, sequences, in no way required to be representable in the current CP_ANSI). Having uninterpreted byte sequences as filenames would work to solve the former issue, and it does: I think most functions in os will accept bytes paths as input and treat that as a signal that you want bytes paths as output (if any). For the latter the cleanest solution is probably an abstract Path type—and you get one, in the standard library’s pathlib. That didn’t work all that well in early Python 3 versions, but it does now. (And IIUC inspired Rust’s abstract-type solution to the problem.)

Not knocking you or general discussion on transhumanism. There's different definitions, and I haven't read up on it enough. Agree that reading glasses isn't a problem, sorry if that's what you thought I was arguing.

The original comment was talking about improving people through genetics and brain tinkering. That's just a modern form of Eugenics, and I thought that we all agreed that this line of thinking doesn't reach anywhere constructive and is best avoided.

Very delicate stuff were talking about here. I'm all for helping cure disease, but some argue that weakens the overall gene pool and opens up the door for superbugs etc. Win a short term battle, lose the war. The stakes are very very high when talking about this stuff. Move fast and break things... just... NO. Much caution.

As I get older, I feel the time is ripe for when the younger generation will make vast sweeping decisions which will end in them relearning the lessons of the past the hard way. Too many voices saying "This time its different" echoing all around me. Too many people willing to tear down too much that has been built. If history isn't learned the easy way, it will be learned the hard way. I guess I'm just throwing out some caution here when dealing with blanket statements about improving humans.
I have some experience in running pretty large compute clusters with NFS as the way everything is accessed, so I feel your pain. We had an environment where all the binaries themselves were in NFS, as well as the data being processed by the jobs (on different servers at least… the ones hosting the binaries were the “tools” servers), and so we had thousands of machines hitting the tools NFS mounts thousands of times per second.

A typical issue was jobs which ran a bash script which calls perl a bunch. Perl is on NFS. Oh and perl isn’t just on NFS, but the path to it is a symlink, which resolved to another symlink, which resolved to another symlink, which finally resolved to the perl binary. So that’s a half-dozen stat() calls per each call to `perl`. (None of these are cached, because metadata wasn’t cached, only the file contents were…) Said bash script would use ` | perl -pe` instead of grep, etc…

Oh and typical perl programs called by these scripts had a bunch of modules they needed. Guess where the modules are? NFS! Not just NFS, but behind their own sets of symlinks (gotta be able to version your perl code! Why not use symlinks!)

Some of these symlinks would trigger an automount. So now your bash script’s call to `perl -pe ‘s/foo/bar’` had to go mount something from another tools server. Yay.

Needless to say we paid the storage vendor a lot for support.
Now to take your tangent fully off the rails, I’ve been looking for new stuff to read and keep coming across that series. How’s the tone, on a scale from grimdark to lighthearted? It sounds fascinating, but potentially a little bit too Black Mirror for fun. Is it?
> you want to take choice away from the majority of consumers

Huh? My worry here is that privacy regulation will reduce the choices available to consumers. If it's legal for some services to offer "pay with ads + fraud detection" and others to offer "pay with your money" we can see what sort of services consumers prefer. In most areas online it turns out its the former. Regulation removes the first option.

> you want that business model for yourself

I'm not interested in running this sort of business; while I used to work in ads I'm not planning to go back. My main perspective here is as someone who uses and enjoys many ad-supported sites (including HN) and doesn't want to see them regulated out of existence or behind paywalls.
Yeah having street car power lines can be a nightmare in densely crowded cities with a lot of pedestrian traffic and tightly packed buildings. It would be a nightmare to implement in a place like New York City, and I'm not surprised that cities that have them are slowly removing them.

Don't get me wrong, I think they are a great solution electrically and for efficiency / sustainability, but require an enormous geographic footprint, central planning and a lot of overhead space which is difficult to find in dense cities.
Modern nutrition science has found that each person, at any given time, has a "metabolic setpoint". This is basically a target weight that their endocrine system is trying to keep them at. There's a feedback loop, where below this weight hunger hormones will nudge them to eat more and metabolic hormones will lower caloric expenditure (lowering body temperature, sleeping longer, fidgeting more). And vice versa above this weight.

Most people will have a +/- 25 lbs window, where the feedback loop is minimal. But once they step outside this window the nudges become increasingly strong. This is why it's generally easy to lose 15 lbs, but really hard to lose 50 lbs. Also why many can lose weight under very targeted lifestyle interventions, but rapidly snap back as soon as they relax even a little bit. Finally it's why the vast majority of normal weight people don't need to count calories, their metabolic setpoint intuitively matches their appetite to their caloric needs.

"Eat fewer calories" is technically a solution, in the same way that "stop drinking alcohol" is a solution for an alcoholic. The problem is someone who has an obese-level metabolic setpoint will literally be ravenous 24/7 once they get down to healthy weight. If you haven't experienced this yourself, try fasting for 48 hours, putting out a bowl of chips on the table in front of you, and resist the urge to eat even one while you try to do something else. That is what it's like to be an obese person trying to lose a large amount of weight.

GLP-1 agonists work by short circuiting the hormones that regulate hunger. It's basically the equivalent of moving your metabolic setpoint 100 pounds lower. The need to explicitly count calories no longer exists, because your appetite will naturally limit itself well below the point of caloric expenditure.

Apparently not always easy to fly, but the Starfighter was an incredibly amazing design very ahead of its peers. Afaik this fighter could supercruise. It had tiny thin wings, very low drag, and clever mechanisms to cope with low speeds or higher AOA.

https://en.wikipedia.org/wiki/Blown_flap

Some hated them; notably one of the Luftwaffe chiefs at the time.

Disadvantage of the small low drag wings is that the aircraft cannot sustain a tight turn, as the aircraft bleeds off too much energy. So in a dogfight versus say a delta wing (low wing loading) like Mig-21 the F-104 will run out of energy.

But this is the sort of fighter that will use superiority in numbers and stand off weapons to inflict a blow on the enemy. It's not an air superiority fighter, but more of a first wave interceptor to inflict hit and run damage.

The power lines that trolleybuses use don’t cover an entire city. They’re only installed on the routes the buses are scheduled to run on, and only for the parts of the streets buses will use. They’re like train tracks in that way, but hanging in the air instead of embedded in the ground.

Garbage truck fleets are expected to cover every street and every block in their service area which adds up to more of a city than bus services cover since they don’t stop on every block at every house and building. The lines also require maintenance and you also need to train operators to re-establish the connections not if they drop but when they drop. Doesn’t seem worth it to me, at least not for New York.
