In my field (bioinformatics), there is a trend of using a single hash function, an over-sized bloom filter which is then compressed with something like entropy optimal RRR[1] or RoaringBitmap bit vectors.
The resulting bloom filter ends up taking the same space than a properly sized bloom filter. There is two advantages: knowing the size of the set in advance is not necessary, and a single hash computation and memory access per query. However updates are not well supported.

I suspect that the number of people that have to travel long distances (or across a lake) to get something from USPS are pretty rare, so Amazon's just eating the cost.

Also, the number of people that actually call/IM customer support for a credit is probably fairly low- until everyone starts holding their feet to the fire Amazon will continue to eat the cost.

This comes off sounding incredibly naive.

When you're picked up, and sitting in jail, nobody gives a shit about your medication. When you end up getting a part-time sentence (Come to jail on Friday night, leave on Monday morning for X weeks) for a misdemeanor, nobody gives a shit that you're taking prescription medication for a chronic issue, either.

You might be getting counterfeit boardgames, but the slightly different colors on the cards isn't a great tell.

Manufacturers are not great at getting card color to match, even for the same item, even in the same manufacturing run. I've got three kickstarters that have outstanding shipments to send out replacement cards because colors were mismatched on the backs in the very same box, and more that have already done it.

I've only purchased Kingdom Death Monster expansions from the official store, and card colors are hit and miss.

QC on color accuracy is pretty shitty in the popular factories used to produce boardgames, unfortunately.

Im not sure if it's so hard. There already exist a strong narrative that it wasn't so bad,and severe misconduct and negligence must happen for a big disaster. And that in absolute terms it wasn't so bad.

I thinkits easy to politically argue for nukes. They are like planes, when they crash it's a big deal, still comparatively safest method.

I am not a fan of mass producing waste that renders some area or space inhabitable for most of life, for longer than our written history or even our species. Though, maybe it's better than burning fossils as a mean of getting to
something cleaner and safer (and cheap). Tough choice.

I think i'd nuke waste and some disasters over greenhouse I guess, especially runaway.

The insides aren't bad. Not on in the league the Richelieu library, but ok. The greenery is nice-looking, but it upsets me I can't actually walk down there. Feels isolating.

But it's the outside that's truly awful. Living to the north I had to walk the entire length of the building to get to the only open entrance at the south. The entire space on top is eerie: wast, windy, exposed, gray, empty, with four impersonal gigantic building towering in the distance. No a person in sight, no one reading a book on the bench (no bench either), no one chatting with a friend, no one decorating their place of business. The ultimate anti-human space. It all makes you feel small and insignificant. It's the same feeling I got from walking the Nazi party rally grounds in Nuremberg - being completely oppressed by the scale and indifference of the architecture. In the latter case it was obviously intended, but I have to wonder what happened with the Mitterrand library?

It all stands in stark contrast with, say, the Notre Dame. There are tourists upfront, there are locals in the park behind the building, there is always someone reading a book on the bench, there are children playing, there is tree cover, there are flowers, and if you walk a couple minutes you will be on the riverbank that actually has people on it (mostly locals). Keep walking along the bank and you will find someone practicing a trombone or a violin during their lunch break, or an evening waltz party on occasion.

1. Part of the problem is that large companies are no longer blocking competition; they're acquiring the competition. (eg. Many of Facebook's acquisitions, many of Disney's acquisitions). No need to block what you can just own.

At least you can say that Germany kickstarted mass manufacturing of PV modules. So even if Germany itself didn't benefit, everybody else did. Including Chinese manufacturers. So I'd argue that the money was well invested.

The Energiewende is actually one of the reasons I still live in Germany: I want to see how it happens. It is stuff that our grandchildren will be proud of. And by the way, private energy consumption is heavily taxed (for a good reason), yet energy hungry industries are exempt from it. And they feel the effect: because of the growing effect of the renewable energies, they now pay one of the lowest electricity prices in the world.

There are actually good books that explain how all this works, why there are also short term "unsuccessful" years and how about everything will benefit in the end. And, most importantly: why the Energiewende actually enables a comfortable, good life.

I don't really know how you can understand Feynman diagrams without seeing how annihilation and creation operators act on the vacuum. They are the mathematical building blocks of qft; formally they are linear operators that represent the creation or annihilation of particles.

If you apply an annihilation operator to a state containing no particles then the string gets deleted from your equation. Moreover if you swap the order of two operators you get an artifact (they're matrices after all), so a•b = b•a + c and so in qft calculations you swap your strings of operators around until you end up distilling it down to just a few non-vanishing artifacts that can be calculated. There's something called wick's theorem that the result of this process can actually be mapped onto a graph if you specify the initial and final state.
The problem isn't economic theory. The problem is bad incentives. Economists like Krugman make predictions for political reasons, because there's incentive to do so (in this case, to try 'help' the left-wing establishment).

Want to find economists who actually make accurate predictions? They'll be working for banks and corporations, getting paid millions. Because knowing which way the economy is going makes money. And money doesn't have political beliefs.

If they aren't homeless, they pay property taxes, directly, or via their landlord.

If they buy anything in a state with sales taxes, they pay sales taxes.

If they legally own a car, they pay vehicle taxes. If they buy gas for that car, they pay gas taxes.

Nearly every man, woman, and child in the United States pays taxes.
Perhaps. But any company who makes the claim of pensions or "we'll promise to pay you more later" should be legally required to store that in escrow.

So if/when they try their little bankruptcy schemes, it won't work.

>..As bad as Chernobyl and Fukushima were, MUCH worse accidents are possible.

Chernobyl would have been illegal to build anywhere else in the world since it was such an inherently dangerous design. It isn't really fair to compare it against reactors built anywhere else. At any rate, when you say "As bad as Chernobyl and Fukushima were, MUCH worse accidents are possible." - you need to back that up with something. We've had hundreds of reactors producing hundreds of TWh of electricity per year for decades with less loss of life than any other power source.
Not sure how you reach that conclusion about regulations which are separate from taxes
do you know how many bits of depth the raw frames for Pi Camera V1 and V2 have?

Do we know the "gamma" curves, i.e. numerical intensity value as a function of light collected proportional to the number of photons?

67dB = 6.7B => brightest over softest intensity = 10^6.7 = 5 000 000

thats ln(10^6.7)/ln(2) = 22.257 bits, that's unheard of for camera sensors I have looked up, so I assume the reported values are "gamma" compressed before digitization.

Would you have interest in characterizing or collaborating on characterizing the exact compression function for the V1 and V2? Relevant literature seems to be Steve Mann's comparametric equations: https://en.wikipedia.org/wiki/Comparametric_equation

(I am interested in high dynamic range, and high monochromatic or color bit depth for an experiment, which will progress much faster if I can start out with a higher dynamic range and bit depth sensor, I will need to oversample to observe a phenomenon, and every bit of increased depth a sensor has compared with another sensor would mean the experiments can be run 4 times as fast...)
There is a tradition among mainstream press outlets of taking battery-related research, misreading it in a way that makes it sound more impressive than it really is, and publishing breathless articles about how revolutionary it is. This article continues the tradition.

The Electrek article claims that the researchers made a cell with "an impressive energy density of 460 Wh/Kg". But the Nature paper says that they made a cell with "460 watt-hours per kilogram of total composite electrode". These are not the same; a cell contains other components besides the electrode: the anode, the electrolyte, and the package. The paper doesn't state the overall energy density (at least in the abstract), but it will surely be much lower when other components are counted.
The iPhone brought mobile internet browsing into mainstream consciousness; we were already addicted to the Internet before it arrived, so it's no wonder that iPhones and smartphones took off.

The Oculus on the other hand has to provide not just good ergonomics, but also content that showcases the hardware well.

I had a Galaxy S7 and GearVR headset in 2016. Some of the games were cool like a TRON-style Pong game, but most of the content was awful, stuff like "explore a famous museum", which was all badly optimized, pixelated 3D video.

Even if Oculus launched with a VR version of a product that's known to be highly sticky engagement wise (e.g Fortnite), I don't know if people would go for it. Fortnite is already on every device anyway, are people really so into it that they want to be fully immersed visually when playing?

How do you know you're never received a counterfeit item? Many counterfeits you probably can't tell are counterfeit unless you have the real item already and do a side-by-side comparison.

For example, would you be able to tell if you got a counterfeit tumbler?:

I think I got counterfeit wallet a couple years ago, but I just suspected it of being not built to last, not counterfeit, until I read something on HN last week about Washington State making Amazon get rid of toxic school supplies. I was inspired to look up the wallet again and I found an extremely similar if not exactly the same wallet from a reputable brand but the one I bought was unbranded. I only knew the brand was reputable because I bought something from them before. I'm going to order a new wallet... straight from their site.

The thing is, and we do not collectively teach young, is that many decisions are workable but some have bad consequences that are nigh irredeemable. Then there's the sunk cost fallacy, all too common. Estimating the cumulative sunk costs and arriving at robust decisions is feasible.

Choosing a college may be a cost, but for now there are workable alternatives.

And you always have the way to know or at least roughly estimate which is good enough for a sane decision.
You just take the cost of acquiring information into your decision time and you're gold. Apply hard limit for time and problem disappears. You did the best you could given the constraints.

In fact, the typical problem today is that you have too many ways to know and not enough ways to verify veracity.
One of my favorite uses of bloom filters was a proposal for source routed multicast some years ago. To work, it simply had the packet originator add all the next-hop addresses to a bloom filter, which was then the address of the packet. Each receiving node would then simply see which next hop nodes matched the filter and forward the packet to them. Fast, small, computationally cheap, bounded in error, and elegant. I liked it.

https://archive.org/ is preserving it by letting you play them right in the browser via emulators compiled to Emscripten.

For example here is the Macintosh version of Dark Castle, which I spent some number of hours winning at the time (circa 1986, digitized sound was still a brand-new thing) https://archive.org/details/mac_DarkCastle_1_2

If you hit "Options" you'll notice the familiar WASD keyboard control layout. Well, this is the earliest game I'm aware of that used that layout...

Here's The Dungeon Revealed, an early Mac dungeon-crawler I also spent a lot of time in: https://archive.org/details/TheDungeonRevealedMacintosh

Here's Crystal Quest, the first color Mac game (although the emulation is in black&white which was also supported): https://archive.org/details/CrystalQuest_2_2_5M

Here's NetTrek, one of the first LAN multiplayer games I ever played (was fun!): https://archive.org/details/NetTrekTheRealVersionMacintosh

And then there is Bolo, the one game I wish there was a modern-day version of that is remotely similar: https://archive.org/details/BoloMacintosh (Wish this was the color version, but anyway... It was a network tank battle game where you could capture points and build autotargeting defense turrets by harvesting trees via sending out your tank pilot (who was then vulnerable and could get killed, the respawn penalty was not trivial as I recall), it was INCREDIBLY fun at the time, literally hours in the computer lab with a group of other nerds)

It's amazing that I can even give other people a hands-on look at this stuff in their own browser. It's too bad that I can't show off the early network-gaming the same way (firing up Bolo or NetTrek in different browsers on the same LAN... It's probably possible to do, right?)
