It's not the parking spots - residents have zero interest in walking to the end of their block with garbage.

> only a handful of days of snow in the year

I know modern economy has gone full-JIT but I naively wish we could just stop in this case and.. wait.

Then this question of truck fleet would be moot.
There's a few hundred sets of numbers that work, but none are the sequence 1,2,..,12 or so, due to needing balanced left and right weighings. To see this, write the base 3 values for 1,2,..,12 as columns, and count the number of each digit in each row - you need equal numbers of 0 and 2 per row to make a valid weighing.

Here I picked the above since it is a valid sequence, but fails for the reason elsewhere on this page - you also need to not have negative paired columns. And that too turns out to not be enough, so write a simple program and crunch to check each case that does work, and there's (I think) 304. I should stop poking at this as I have real work I should be doing :)

If you really want to clean it up, you could then map the answer 3-vector of scrambled -1,0,1 values into another decoder matrix to map into values you like. Or use a look up table.
> The Great Illusion isn't wrong. Economic interdependency is a deterrent to war. It's just that its not a very good one,

The premise of The Great Illusion is that international trade is a very good deterrent to war. The book doesn't argue that it's an 'okay-ish' deterrent to war, it claimed that WW1 was extremely unlikely to occur and that if it did, it would be over quickly. Not only did WW1 happen, so did WW2 a few years later. Neither war was short, and even more and bloodier wars after WW2 would have been a damn good bet if not for the invention of nuclear bombs.

Awesome work! It takes a lot of guts to go out on your own and bet on yourself. I did that over two years ago and I'll never regret it - the amount of time I get to spend with my kids is incredible, and serving customers that use and love the tools you build is a great feeling.
Aha - very nice!

My background with Fourier optics is mostly theoretical and the applications numerical.

Any references (books or online) exist about physical applications, like the one you mention?
I understand. Unfortunately, we have wildly different preferences and keyboards.

If I had Function keys: F1 = help, F2 = rename, F3 = repeat search, Alt+F4 = close, F5 = refresh, all context dependent, of course

On a Mac: Help = help, Return = rename, Command+G = find again, Command+W = close, Command+R = Refresh, usually consistent.

Maybe, one day, there will be truly customizable keyboards.
Why have garbage trucks at all when you can have a series of tubes to transport garbage?

NY has a lot of row houses, there's no room for a dedicated garbage area. And the alleys are not wide enough for a garbage truck.

Before criticizing a place, at least understand it first.

Apple headset leak reveals new details and confirms earlier rumors
Theoretically, you're attempting to remove the artifacts that were added back in by the halftone printing process and recover the original image. If you knew the exact noise spectrum that the halftone print added into the image, you could invert it. For example with some scans of halftone prints of known images, you could reconstruct that noise spectrum and remove it as best as possible. This would preserve, to your best ability, whatever high-frequency data existed in the original image.

If we were sure that the halftone resolution was smaller than the relevant details of the photo, then we could just use a low-pass filter (a circular aperture), removing all the high-frequency components from the halftone print, but keeping the details of the photo. However in this case, the photo has details that are at the same scale as the halftone.

So the next best thing is to try to infer the halftone noise spectrum and subtract it, which is hard because it's mixed in with the photo, and we don't know which spectral peaks are from the photo and which are from the halftone process. What we can guess is that the legitimate high-frequency information in the photo should be pretty random, meaning it will be smeared out across the fourier spectrum, while the halftone print will be strongly periodic - concentrated into dots that are nearly symmetrically distributed around the origin (with some radial pattern that depends on the print process), away from the low-frequency center point.

Based on this we guess that any big dots that are symmetrically placed around the origin are probably more halftone noise than image signal, and any grey areas between them are probably more real image data than noise. Then we fit a noise filter to the dots with a regression, doing our best guess to invert the noise, bringing the whole high-frequency zone to approximately a uniform grey.

And then we hope that the picture isn't a photo of a herd of small spotted leopards.

Why do you think we don't? Different teachers, institutions, and educators have used differing curricula and systems and styles education for all of history. In modern times in civilized countries (and states) they are even required to update their knowledge over time and interact with other educators and experts to improve their techniques, knowledge, and systems. Large government education bodies regularly try to put a scientific spin on the process but it's often clear they aren't being rigorous or honest with themselves.

If your local educators are not required to participate in this system of continuing education and improving techniques, that's a local government decision and you should seek to fix that.

Fixing it is often hard in the states because there is a not insignificant amount of Americans that see schools as undermining their authority, see education as a useless and undesirable endeavor, often as a "radicalizing" and "socialist" influence and institution, and so they fight back against any improvement of schooling. There are states in the union that allow pretty much anyone, with no qualifications or certifications, to become "educators", and other states in the union that require a masters degree and 12 credits of class work every few years to continue to be an educator. Outcomes often imply a correlation between those requirements and the result, and yet the states with much lower bars of entry do not increase them. Education in the states is a politics issue, for some stupid reason. There are people who believe for whatever reason that middle schoolers are being taught "Critical Race Theory", as if that isn't a college level course that the vast majority of humanities majors don't even experience.
I remember looking into this a little bit and the conclusion seemed to be that for most garbage truck uses the range was not the limiting factor. Pickup time was more important, and batteries are attractive given that most garbage pickup is stop-pickup-start-drive a short distance then stop again. In Seattle I believe I saw the longest route was less than 70 miles but I can't find a source. There was a purchase of battery garbage trucks with a range of 55 miles a few years ago. https://arstechnica.com/cars/2019/05/seattle-makes-history-w...

Caternary lines have always seemed like a good solution but there must be a good reason they aren't more popular.

Not OP but I do. If I had a plate of steamed or roasted broccoli available on demand at any time, I would eat it like most people do chips. Broccoli tastes great, but requires a lot more prep than “junk food” to get there.

I eat junk food mainly because it takes me no effort and still tastes good: for me the addiction is not having to put in any effort to be satiated, more than the taste itself.
> If your strategy involved needing to take advantage of network effects, growing as fast as possible seems like a requirement.

Not necessarily. Most businesses with network effects (including Facebook) follow the "come for the tool, stay for the network" approach.
They should buy and maintain a separate fleet of trucks for those few days per year? This is NYC; that's going to be a lot of trucks. Even parking them - for 3xx days per year - would be a problem.

They already have a fleet; it seems like a creative, effective solution - the kind of creativity that cynics say government lacks - to repurpose them for snow removal.

Top Predictions for Web3 Security in 2023
It's not just SaaS or web based products that fall into this category. There are plenty of applications and systems that run stand-alone on a disconnected computer that can add real value and may take many years to develop for a sole engineer.

I have a data management system that I have been working on for many years. It is core technology that could eventually be used in a SaaS or web based model, but for now it runs on a single computer with no dependencies to the Internet (other than to download the beta software at https://www.Didgets.com).

Many of the features (file system imports, database tables, quick analytics, logging framework, indexing service, etc.) have come about one weekend or a series of evenings at a time.

There is only one class of drugs that lowers appetite outside of these GLP hormone drugs, those are stimulants like amphetamines. As someone on one of the GLP drugs for 3-4 months, and whose body tolerates it well, this is simply turning off the hunger switch. I will miss meals because I'm not hungry, since starting I have never felt "hangry" and I am satiated with small meals and do not feel hungry later. If I overeat, I will feel nauseous and sick.

I do not feel wired, foggy or feel like my personality or sleep cycle has been affected in the slightest.

I've seen cheap laptops where the battery lasts but for the expensive ones (that say have a discrete GPU) seem to have good battery life for a few months.

Some of it might be that the big ones have to abuse the battery we had since the T.S.A. won't let you take a big laptop with an accordingly big battery on the plane.
Thanks, this gives me something to look into. I've been too busy the past few years to fly my long range planes and need to catch up on what's changed.
Meh, I think the idea that X party is unorganized while Y party is organized is overstated.

Democrats and Republicans are pretty good at opposing measures while not great at supporting them. Currently, voting for X democrat won't actually cause anything to happen so its easy to all vote for the same guy cause there isn't a consequence. Democrats can't actually get 218 votes so they individually have no reason to bicker about which of them should be elected.

This is complete and utter nonsense. Obscenity is not and was never protected by the first amendment. Porn was considered to be obscene when the 1st amendment was created.

The intent of the 14th amendment was not to push the bill of rights onto the states. This was a development that occurred well after the 14th amendment. The earliest you could argue the 14th amendment creating incorporated rights is 3 decades after it was created though many people consider it to be closer to be 50 years after the 14th amendment. The incorporated rights interpretation is extremely dubious and was not the intended purpose of the amendment.
Even humans use few relatively simple heuristics to decide what to trust.

One is that objective truth is internally self-consistent. If one AGW denier claims it's the sun, and another AGW denier claims the NASA falsifies the data, and they support each other, then you can judge these are conflicting claims and decrease your trust.

Also, false claims usually focus on attacking competing claims than to come up with a coherent alternative. And they tend to be more vague in specifics (to avoid inconsistency), compare for example vague claims about all scientific institutions faking data vs Exxon files containing detailed reports for executives.

That's a nice point for some aspects: we have (had) all over the world trolleybus of various kinds, those on rails have some co-existence with cars and asphalts issues (like slippery passages for bikes, complex ops when the asphalt need to be re-do etc) but beside that have worked HYPER well for decades. Those on tires have proven to be full of issues to a point most who have had them have given up.

I see so far no feasibility study about:

- converting highways to rails with dual-usage vehicles (all vehicles, cars and trucks banning bikes) so vehicles can run normally on road but for just the long range usage they run full electric form grid, converting them to wheels only for going out or maneuvering on a faulty vehicles;

- crafting a urban rail network again at least for some "important traversing roads".

Perhaps the result would be negative anyway, but at least a broad simulation with public discussion, some eventual experiment etc...

Hm, I think the author has got the causality wrong here. The direction of the tech industry is not a result of learning style. Rather, the tech industry goes in the direction of the incentives presented to it, which are largely capitalist in nature, and secondarily due to aggregate preferences and tastes of the various practitioners (which include UX, domain interest, taste in technology, etc). I believe on-demand learning naturally dominates in this environment because the goals are very pragmatic and short-term go-to-market concerns. Of course, when expand beyond the narrowly defined "tech industry", goals could be completely different. For example, pushing the boundaries of mathematics or astrophysics obviously requires a huge amount of preliminary learning to even start to make a dent.

But this brings me to where I really disagree with the article:

> Putting it bluntly, on-demand learning is excellent for learning tools, but it sucks at learning concepts.

I could not disagree more about this, in fact I think it's borderline gibberish. First of all, you can absolutely learn concepts on-demand, and in fact a concrete use case can often make the concept much clearer than if you learned it from first principles. Secondly, of course tools are easy to learn this way, since a tool is a thing which was already thoughtfully designed for a purpose—if your goal is to quickly get something done, and a tool is available, of course that is likely going to be your first choice.

Overall preliminary vs on-demand is just about time horizons and they are not mutually exclusive. For example, I don't see any shortage of programmers continuing to learn over the long-haul and develop new concepts and practices inductively based on years of short-term focused work.
I was doing J2EE and was hardly surprised with Rails.

We did Rails one decade earlier with our own version of AOLServer.

The very reason we went to .NET (as beta testers during its availability only to MSFT partners) was because we were fed up having to rewrite TCL into C due to performance issues.

All the Active Record stuff was already something that AOLServer introduced, and we had an improved approach on our product.

The founders of that company went on to create OutSystems based on our learnings.
We found that they could not plow the snow effectively – they basically conked out after four hours. We need them to go 12 hours.

Unfortunate, this is their loss, offering education is low hanging fruit for having more competitiveness in hiring.
This and also: NYC residential trash collection is curbside. Literally leave trash bags on the curb. Trash collection cannot occur when the curb is snowed in.

So, were there separate trucks for the two tasks, the trash trucks would sit idle until after the snow plow trucks had finished their rounds.

Given the infrequency and relatively small volume of snow NYC gets, plus the curbside trash collection, sharing trucks and drivers is reasonably efficient.

It does not show that thinking or memory are absent before language acquisition or in people who never acquire it, which was implied by the comment I was responding to.
