I've seen a study done not that long ago for a small to medium sized German city. The idea was either taking the existing bus service and expanding it to a 10-minute-frequency all-day on all routes, or else keeping only the three most important (regional) bus routes and replacing everything else with a massive fleet of on-demand vehicles.

The surprising results:

- According to the results of the traffic modelling, the on-demand scenario wasn't substantially more successful in attracting additional passengers than the "classic buses running every 10 minutes" scenario (i.e. in both cases predicted passenger counts increased, but by approximately the same amount). This was because on-demand public transport has quite a bit of time-wise overhead, too: You need to order a vehicle instead of simply showing up at the bus stop, it takes a while for the next vehicle to arrive, due to ride sharing some detours might be incurred compared to a direct route, and the unpredictable journey time variation due to these factors is very disadvantageous when connecting to fixed-route fixed-timetable public transport, such as the remaining three bus routes, or railway services.

- The overhead of operating a large fleet of on-demand vehicles was high enough that even with driverless operation the on-demand scenario was more expensive to operate than the expanded every-ten-minutes bus service with drivers

Why are Chrome sidebar extensions so unpopular?
I found that Chrome's sidebar extensions don't seem to be very popular. I created an extension called VertiTab, and people installed it and then uninstalled it. I looked at similar extensions and it seems that no one likes the sidebar design very much. It's really frustrating.

I was an adult and had been independent since 17. I do not recall the hospital ever asking me for contact info. I had nothing on me except my keys, no id. and frankly by the time I had got there in cuffs and realized what was happening was not in a great mood to cooperate, either.

I know for a fact the school never contacted my emergency contacts but there wasn’t really anyone to contact to begin with so I don’t fault them for that.

What should have happened was I referred to a school therapist or actual doctor.

To explain further what this place was like - it was the county mental facility at a large hospital. imagine a toned down version nurse ratchet kind of setting, people defecating on themselves, screaming, people in straight jackets. and then me, a slightly disheveled kid who was stressed about finals. they wanted me out of there immediately once they realized what was going on because they were already full. then when they process the paper work you get shuffled to a front desk behind a window who just wants you out of their sight ASAP. I remember I had to actually argue for the bus tokens and the woman seemed exasperated with even that.
Microwaves: A Haven for Bacterial Diversity
Yes, that's correct and confirms what I just wrote.

Dutch example: 0,12 EUR / kWh assuming 5000 cycles with 0 degradation. Example source: https://www.otovo.nl/blog/kennisbank/lfp-batterijen/

The real number is likely still significantly higher than 0,12 EUR / kWh due to battery capacity (and charge discharge efficiency) going down due to wear over time.

It does look like when the price of integrated storage products goes down more, it could become interesting for countries who have had very expensive energy policies (Denmark, Germany, Netherlands etc).

Maybe it'll help here to point out that if you start with a spinning black hole there's an easy way to stop it spinning. You just chuck in matter with the angular momentum going the opposite way to its spin until all the angular momentum has cancelled out.

This explanation strikes me as euphemistic. Though it has some insight as well: "(and why it courts controversy) it is interventionist".

> Part of the role a phrase like “differently abled” plays is to estrange your base assumptions about disability and to signal the existence of and your membership in a group of people concerned to change the conditions around disability

Less euphemistically, you want to make other people think and act differently. And if disingenuous language policing or the threat of condemnation by said "group of people" gets the job done, that's just fine.

Naturally a policy only added after PlayStation 2, as PlayStation 1 only did C and Assembly, being famously the first devkit to offer C support.

Also the SPUs on the Playstation 3 could in theory be programmed in C, but really only Assembly was usable for the goals of using them.

Finally, some Playstation Studios also use Unity with C#.
A very natural explanation of "wikipedia proof 2" for differentiable functions seems to be missing:

By linearity of expectation, both sides are linear in f, and for linear f we have equality. Let's subtract the linear function whose graph is the tangent hyperplane to f at E(X). By above, this does not change the validity of the inequality. But now the left hand side is 0, and right hand side is non-negative by convexity, so we are done.

It's also now clear what the difference of the two sides is -- it's the expectation of the gap between f(X) an and the value of the tangent plane at X.

Now in general replace tangent hyperplane with graph of a subderivative, to recover what wiki says.

If this is not a strategic defeat then I struggle to think of what a defeat would actually look like. Ukrainian Troops entering the Kremlim?

They managed to:
-get Sweden and Finland to finally join Nato

-completely demolish their entire military export potential

-lose half their warchest because they kept it in foreign banks

-lose all kinds of prestige the „mighty“ russian military had

-severely diminish the arms stocks they had left over from the soviet union

-lose the flagship of one of their fleets to a nation without a navy

-publically had one of their mercenary companies march on their capital in revolt

In exchange the land might gain from this is going to be completely devastated from the war.

Compare all of this to the 2014 fiasco where they ended up with crimea in exchange for some minor-ish sanctions,

It’s just harder to produce significant gains now. A 10% might be the result of all the chip giants giving it their absolute best.

I wouldn’t draw conclusions about the level of competition simply based on the spread in performance.

Remember that with Olympic runners the spread is 100ths of a second. And yet the competition is fierce.

You may not be excited about a 10% improvement. I am not either. But that’s a different matter.
Ask HN: How to help open sources improve their UX?
I have some students I am teaching design. I want them to work on some real-world projects and not redesign interfaces without having a feedback loop telling how they did. I can't give them access to my client work.

Is there a way to find out open source projects that want someone to help with their User Experience?
Or maybe you’re just exaggerating. I’ve done my fair share of copy pasting and it never worked to just do it without understanding what’s going on.

I think the problem with “AI” code is that many people have almost a religions belief. There’re weirdos on internet who say that AGI is couple years away. And by extension current AI models are seen as something incapable of making a mistake when writing code.
>People with agendas will happily feed others narratives about the US not investing in manufacturing anymore, but it isn't true.

It's a matter of perception. Most people don't directly see (or buy) the stuff manufactured in the US these days. Normal people don't buy nuclear power plants, aircraft engines, commercial aircraft, etc., and certainly not military hardware which the US makes a lot of. They do buy clothes and various consumer electronics, and they see "Made in China" (or for some clothes, places like Bangladesh or Vietnam or Cambodia) printed on all those, when 50 years ago all that stuff had "Made in USA" printed on it, or for the nicer consumer electronics 30-40 years ago, "Made in Japan". People still might be getting a CPU for their laptop computer manufactured in the USA, but the chip will probably say "Made in Malaysia" because only the silicon was made in the US, and was then shipped somewhere else for packaging.

>However, manufacturing does represent a lower percentage of our GDP with each passing year, despite the absolute value increasing.

I'd say that's probably a bad sign: what other sectors are increasing? Likely they're things that aren't actually productive, such as healthcare (the value received does not represent the price paid in the US by a long shot, compared to other advanced economies; most of the money goes to insurance companies and waste), legal services, ever-increasing real estate valuations, etc.

Double whammy is that his co-accused in the fraud trial was killed by a car the same weekend - https://www.bbc.co.uk/news/articles/c74jzd22dkno

Someone mentioned "hallucination-based API design" on twitter (I cannot find it now). It's designing API by LLM hallucination. If there is a common hallucination API call, just add that API. This will make the API more "friendly" and resemble common similar APIs.

Considering that LLM can hallucinate in different ways unpredictably, not sure whether it will work in practice.
I suspect there may be a flaw in the visualization where smaller dots are drawn with disproportionately more pixels than bigger dots.

The awful thing is, I'm not sure they can.

I don't follow any of them anymore, because they all either want out of business or gave up and switched to advertising hell.

The other problem with simd is that in modern cpu-centric languages it often requires a rewrite for every vector width.

And for 80% of the cases by the point there is enough vectorizable data for a programmer to look into simd, a gpu can provide 1000%+ of perf AND a certain level of portability.

So right now simd is a niche tool for super low-level things: certain decompression algos, bits of math here and there, solvers, etc.

And it also takes a lot of space on your cpu die. Like, A LOT.

Neurotypical refers to brain stuffs though, it's mainly used by the people within the neurodiversity communities (think autism, adhd, etc) to identify those outside of it; I don't think it communicates gender or sexual identity at all. But likewise, cishet is mainly used by the LGBTQ+ community to identify those outside of it.

Either label is probably wrong, of course. That said, I understand why labels / identifiers are used and needed. One thing to point out though, rejecting labels like cishet can easily be construed as "I'm normal, no need to label me", which in turn means you see other gender- and sexual identities as abnormal, which is the core of the problem.

(I'm making loaded and generalised statements, nothing personal to the commenter I'm replying to)

The main issue isn't the label, but that people perceive a label as a slur or an "othering", which is hurtful.

> Often this takes the form of trying to access an endpoint that does not exist, or read a property off the API response that does not exist. After probing a bit more, my suspicions are usually confirmed — ChatGPT hallucinated that endpoint or property

In some cases, you might be able to use this to your advantage to improve the product.

When working with third-party APIs, I've often run into situations where my code could be simplified greatly if the API had an extra endpoint or parameter to filter certain data, only to be disappointed when it turns out to have nothing of the sort.

It's possible that ChatGPT is "thinking" the same thing here; that most APIs have an X endpoint to make a task easier, so surely yours does too?

Over time I've sent in a few support tickets with ideas for new endpoints/parameters and on one occasion had the developer add them, which was a great feeling and allowed me to write cleaner code and make fewer redundant API calls.
I wonder how history would be different if Hitler had told France and UK to f** off with the WWI reparations stuff, threatening a war if they tried military action to force payment, but then didn't invade anyone and concentrated on developing their economy and becoming a technological and manufacturing power.

Go structs are nominally typed, so that is beyond the topic of structural/duck typing. Only the interface is structurally typed.

The difference between structural typing and duck typing is that one is evaluated at compile time, while the other at runtime. Typescript is erased before runtime, so it by itself does not exhibit duck typing features, although Javascript does.

I've got a tinfoil hat that says this AI hype cycle is ~20% no-kidding tech, and ~80% fig leaf for offloading expensive employees.
What likely happened is that he asked the AI two separate questions and fused the answers himself.
Even if users don't read them of their own volition, they're still valuable. You can copy/paste responses from them, link to them, or hell just use them to remember the answer yourself later without having to confirm it or even think about it.
I agree with you. In the 2000s, what you describe was normal for Excel/VBA. The trick to learn VBA from nothing, was to use the macro recorder, then slowly modify the code. And, arguably, Excel formulas was/is functional programming.

Heh, nice! This article reminded me of a great talk I recently noticed:

Rethinking Binary Search: Improving on a Classic with AI Assistance: https://www.youtube.com/watch?v=FAGf5Xr8HZU

The gist is rather simple: Assuming that a substiantial amount of your searches results in no result, you can bias the binary search to jump farther then just half, improving runtime noticeably.
This.

Keep in mind people that a job interview is to check wether you want to work with the person, not to judge if they "pass" the test.

There's a reason why Tesla picks 10 years (8 years for car batteries) as a warranty period. Ask yourself: why 8 years and not 10 for cars? Why 10 years and not 15 or 20 years for home batteries? It's not arbitrary.

Battery degradation is not linear. It's not like: 10 years = 70%, 20 years = 40%. It's probably closer to 20 years = 20 % capacity left. The decay becomes exponential-like after a relatively linear period of roughly 10 years.

If you want to get an idea, this is what the decay of battery capacity roughly looks like: https://www.researchgate.net/profile/Simon-Montoya-Bedoya-2/...

The Tesla warranty will fall under "first life" in the image in the link above.

So batteries (even Tesla Powerwalls) do degrade and do degrade to the point where you need to replace them a bunch of times during lifetime of a house.

Anything immunotherapy in cancer treatment is extremely targeted. Early trials with new drugs include people getting cooked to death as the immune system and in particular the wrong interleukins get over-stimulated. 'Bolstering of the immune system' sounds good, but in general the immune system is a fine balance between doing the job against pathogen/cancer but not well that it is erring on being nonspecific and attacking self, i.e. autoimmunity. Unless otherwise noted, non-specific 'bolstering' in a tissue like the brain is likely not a good thing.
