None of these hashes are cryptographic. They're designed to be /fast/ and so therefore easier to break. They're mostly only used in developer-controlled situations (hash maps etc) where you probably control the keys (if you don't.. well you're at risk). The risk/cost of a collision (the break) is decreased performance, not a security failure.

Crypto hashes don't have a problem of being slow.. they are designed to be slow.

The conclusion tries to tie weak/fast hashes to crypto/secure hashes (the https mention), but they're worlds apart.

I am not sure what is possible given the political cost (and yes even authoritarian states have political costs) but I think it’s worth noting that economics are much more powerful than any birth rate limiting policy at this point. It doesn’t matter if China raises the limit to 10.

Immigration would be a tough sell but not out of the question. In fact with an aging population China’s options may be highly limited.

Junk mail democracy is the most insecure model for an election I could possibly conceive. Other than entrusting closed source software companies with tabulating votes.
Doesn't the Blockchain, by design, record what is entered into it? So couldn't someone then figure out how you voted?
Decentralised could be each counter putting 5000 or so ballots into piles with people wandering around witnessing for various parties all working a rigid process accross the nation. Each count publically announced in the room before witnesses.

Totally standardised, coordinated, and decentralised. But fragmented (structuraly) or incoherent.

OT: I copied the error detection code that AcuRite uses in their temperature sensors for use in my rain gauge. (I got the code by taking a look at the decoder for AcuRite temperature sensors that is included in rtl_433).

At the time I thought it was a CRC, but later I realized that it isn't. I've been trying to find out what the name is for that kind of code but have failed. I wonder if anyone here happens to know?

Here is the code:

byte check_code(byte const message[], unsigned nbytes, byte gen, byte key)
{
byte sum = 0;
for (unsigned k = 0; k < nbytes; ++k) {
byte data = message[k];
for (int i = 7; i >= 0; --i) {
if ((data >> i) & 1)
sum ^= key;

if (key & 1)
key = (key >> 1) ^ gen;
else
key = (key >> 1);
}
}
return sum;
}

I thought it was a CRC because I saw it shifting and saw it xoring when it shifted out a 1. That's quite reminiscent of the method of CRC computation that treats bit strings as representing polynomials in GF(2) and computes the CRC by doing polynomial division essentially the same way we would do it by hand.

But when computing a CRC that way what you xor the data with is a constant (the representation of the generator polynomial). In the algorithm above the constant is not xor'ed with the data. In fact nothing is xor'ed with the data.

The constant, named 'gen' which is another reason I thought at first it was a CRC, is actually the feedback polynomial for a Galois linear feedback shift register (LFSR), which is seeded with the 'key' parameter. That LFSR generates one byte for every bit of the message, and the bytes that are generated for the message bits that are set are xor'ed together, and it is the result of that that is the check code.

In higher level terms the general approach it is using can be described like this in a Pythonish pseudocode, assuming PRNG() is a psuedorandom byte generator, and seed_PRNG() is a function to seed that generator:

def check_code(message, key):
sum = 0
seed_PRNG(key)
foreach bit in message:
next_random = PRNG()
if bit == 1:
sum ^= next_random
return sum

Pick a Galois LSFR with feedback polynomial 'gen' as your PRNG and that matches the AcuRite code.
You can get devices which fit into a standard circuit breaker slot which perform both functions

in the UK such a device is called an "RCBO" aka "Residual Current Breaker with Over-Current (protection)"

Noted, ty, wont do it again - sucks to be downvoted and flagged but lesson learned
Looks like the classic mistake of every data team. Every single office person works with data in one way or another. Having a team called 'data' just opens a blanch check for anyone in the organization to dump every issue and every piece of garbage to this team as long as they can identify it as data.

That's why you build data platforms and name your team accordingly. This is much easier position to defend, where you and your team have a mandate to build tools for other to be efficient with data.

If upstream provides funky logs or jsons where you expect strings, that's for your downstream to worry about. They need the data and they need to chase down the right people in the org to resolve that. Your responsibility should be only to provide a unified access to that external data and ideally some governance around the access like logging and lineage.

Tldr; Open your 'data' mandate too wide and vague and you won't survive as a team. Build data platforms instead.

The Paradox of Peanuts (2019)
Out of interest is nearest neighbour even remotely effective with 300 dimensions?

Seems to me that unless most of the variation is in only a couple of directions, pretty much no points are going to be anywhere near one another.

So with cosine similarity you're either going to get low scores for pretty much everything or a basic PCA should be able to reduce the dimensionality significantly.
As a fellow 2012 Denon owner (AVR 3313) you can probably remove the RPi and just use HTTP. Just use devtools on your browser to do an action in the web UI and see what request it sends, then replicate it in shortcuts.

And there's a internet radio capability built in - you have to pay $20 or so a year for it but it should be easy enough to set up a competing service since it uses unencrypted HTTP - probably just a matter of reimplementing the protocol and then DNS redirect.
1 million requests in a month is ~0.4 requests per second.

With the Prisma pricing, $1k gets you up to a 48req/s load average, and that's without the geo balancing. For a little more you can get a dedicated Postgres instance with 128GB memory and 1TB+ of disk on DO that would definitely handle magnitudes more load.

Of course there are a bunch of trade-offs, but as the original poster said the gap is pretty wide/wild.

I am completely ignorant of all things automotive. I was under the impression that any relatively recent (15 or so years) ICE car also operates by way of a car computer, and that stepping on the gas pedal is just a way to politely instruct the computer that you would like it to apply throttle. And that for even more recent cars this also applies to braking (since the newer cars can brake automatically). Have I got it all wrong?

If not, what's stopping a "traditional" (ICE) car from (mis)behaving in a similar fashion in some catastrophic circumstance that would damage its computer?

Ok. My real world counterpoint. I work for a CFO at a multinational. A really big one. I have been the finance lead at a multinational myself, a smaller one.

Our business changes so rapidly that we are forever adding business units, acquiring, divesting, resizing. The ERP people are years behind us all of the time.

What should we do in the mean time with our new group of companies we just acquired? Wait for the IT people?

That seems like it'd be impossible to implement. Either I'd have a record that I voted with no way to confirm who my vote was counted for, or I'd be able to prove that I voted for a specific candidate which opens a Pandora's box of problems (either coercion for voting for the wrong candidate or bribes for provably voting for a specific candidate).

I mean sure, if someone can come up with a workable blockchain-based system that would be good, but I don't think that is an in-practice option on the table right now.

Thanks for the comment here, I'm genuinely curious how I may be seeing it so starkly different from many comments here.

> During one of his early meetings at a team onsite he asked the team, “for this meeting I’d like us to try and introduce ourselves a little differently. If you’re comfortable, I’d like us to try and be 10% more vulnerable than we normally would in a work setting.”

I had to go back and double check the original post here to make sure I remembered it right. This may actually be part of where I read it differently, if I heard a manager say this in a meeting I would have still assumed it was to be more vulnerable in a work context rather than breeching the wall between work and personal life. Maybe I would share a code review that made me feel uncomfortable, not a personal trauma in my life.

For better or worse I do tend to have a habit of speaking my mind, hopefully in a kind way that makes it clear I'm being genuine. I'd speak up in this kind of situation in part hoping that it makes others less likely to speak up feel more comfortable or willing to then speak up.

> Re: your "showing your age" comment, FWIW, I'm in my 40s; not sure if that's old or young by your standards when it comes to this sort of thing

It may not be a generational thing at all. I'm not far behind you, in my late 30s, and my initial reaction could very well have been the bad (and timeless) trope of "kids these days just don't ..."
Without a literature review, they'd certainly be a number one suspect.

Consider this statement elsewhere in the thread:
> before 1985 T2D was called adult onset diabetes considered an adult disease and 1983 was the first case of pediatric nonalcoholic fatty liver disease.

We've eaten sugar and saturated fats for ages. Of course, not everyone ate the same amounts that people do today - but we'd expect someone to be feeding their kid enough bacon (which people ate huge amounts of even ~100 years ago relative today) to give them fatty liver disease, if e.g., its saturated fats, or feeding them enough sugar.

But what people didn't eat, almost at all, was seed oils. Canola oil was not consumed at all before the 1970s - canola is a CANadian scientist created version of rape Oil, with Low Acid - rape oil itself being too poisonous/bitter to eat. Soybean oil was practically unheard of. Cottonseed oil (aka Crisco) was just being invented as a wonderfood, here to solve our problems. Today these oils, particularly soybean and canola, are the second highest source of calories in the average American diet, and the single highest source of fats. We're suddenly beset by major metabolic problems, from heart disease, obesity, fatty liver, T2D, that did not exist or existed in much smaller proportions, even in historical populations where people were eating tons of bacon or sugar. Meanwhile, we have a food source that went from "negligible" to "one of our main sources of calories." It's not proof, there are almost certainly other factors involved as well, but it's really, really suspicious. Making matters worse, what you feed animals also impacts the fat composition of their meat, and we now feed cows and pigs canola and soy.
Electronics (when you start to care about EMI or antenna design), model airplanes (for aerodynamics), rocketry, machining (especially if you want to get into SPIF), robotics, 3-D printing (especially for topology optimization), basically anything that deals with designing solid structures in the physical world.

> Well good thing Lambada is not the only line there.

There are 3 out-of-distribution lines, all of them bad. I explicitly described two of them. Moreover, it seems like the worst time for your uncertainty indicator to silently fail is when you are out of distribution.

But okay, forget about out-of-distribution and go back to Figure 12 which is in-distribution. What relationship are you supposed to take away from the left panel? From what I understand they were trying to train a y=x relationship but as I said previously the plot doesn't show that.

An even bigger problem might be the way the "ground truth" probability is calculated: they sample the model 30 times and take the percentage of correct results as ground truth probability, but it's really fishy to say that the "ground truth" is something that is partly an internal property of the model sampler and not of objective/external fact. I don't have more time to think about this but something is off about it.

All this to say that reading long scientific papers is difficult and time-consuming and let's be honest, you were not posting these links because you've spent hours poring over these papers and understood them, you posted them because the headlines support a world-view you like. As someone else noted you can find good papers that have opposite-concluding headlines (like the work of rao2z).
Startup time is a problem we can solve without giving up the advantages of dynamic systems. We just haven't invested enough in solving the problem.
I doubt I misunderstand it since this is what I get paid for. I'm also not suggesting this is a case of large data, ETL or anything like that. (what I'm writing about is people using it for that anyway which is what we have other systems for and they should not be doing that)

Our finance teams use excel too, but not as the 'do everything' tool that the article and plenty of comments here makes it out to be. They use it as a scratchpad, and it works well. But it doesn't contain ground truth, ever.

This one perhaps matches with 99% of the rant I wrote:

> Then inventory, maybe the ERP didn't split it in the way your consolidation needs it, so you transform the data in Excel and reconcile it back

While we primarily deal with Dynamics (AX and 365), pretty much everything fits in there. In some cases the clunky UI makes it slow to do some transformations, even if just to check something to (as you wrote, verify the software did what it was supposed to do), and then you dump a couple of thousand rows out, do your work, and either are happy with what was verified or load some transformed data back in (this hasn't really been needed as we revised our rules as to data locations a few years ago, not in terms of "do this or you get fired" but in terms of "please make sure that when external systems outside of your team streams data in or out of the ERP, the chance of it not being correct is as low as you can get it").

As I wrote in some other reply (which some people appear to disagree with as if it's something I made up), my issue is with the horror cases of people building their own mini-ERP in a set of excel workbooks, or not using shared systems for data sharing and governance but instead emailing files around. Maybe it's the little learning being a dangerous thing, or feeling confident in a tool also giving people false confidence to perform actions that really should not be done that way.

Colorado does signature matching and ballot tracking. My signature has changed since I registered to vote here and I was notified in one election about it not matching and had to cure my ballot. If someone voted under my name, I would be notified of the processing of my ballot and could object to it. Ease of voting/security is still an important balance. I could easily create a 100% secure election and it would disenfranchise a lot of voters.
Definitely controlled, but a pole to the "chest" of Atlas shows it's relatively stable on its feet and capable of recovery, though we have no idea how many takes that took.

As far as speed, it depends on what the limitations are. We know electric motors in general are capable of moving faster, so presumably the limits are with computation, to which I'd point out that Moore's law is still hanging on. Compared to Honda's Asimo in 2000 BD's Atlas robot in 2016 was nothing short of phenomenal progress, but that took 16 years.

Hopefully it doesn't take another 16, but we'll see. Once there are useful commercially available humanoid robots on the market, progress is likely to accelerate.

From personal experience with older parents... Some very bad UX on the website of Google photos

If you're up for the (small) effort it's easy to make shared albums and you could just do the final step of purchasing the prints and getting them sent to her home.

It seems like arbitrarily ruling out divine meaning as a hypothesis for why the world is unexpectedly orderly is not being entirely intellectually honest. It's like a theist ruling out evolution as a possible cause of our existence. Divine meaning (in various forms) is historically a very popular explanation, and to just rule it out with nothing more than a "we shan't have need of that" (presumably with an implicit "we are so much more superior to those foolish ancients") seems to me to be just hiding from yourself that you've made materialism/rationalism into your religion.

I think divine meaning actually opens up some really interesting possibilities. The 20th century revealed a lot of limitations with a meaningless world. As Nietzsche and others apparently predicted some of the horrors of the 20th century, with godless Communism and Fascism (not sure if Fascism was godless or man-is-god) resulting in the deaths of around 100 million people, and in the case of Communism, destroying beauty and vibrancy and enslaving entire countries to the State. Now the bleak meaninglessness that troubled intellectuals has filtered down into western culture broadly, and the results are not looking pretty so far. But if all the beautiful parts of the world are at all reflective of a divine meaning, that seems potentially much more interesting that meaninglessness.

The divine meaning hypothesis is not scientifically testable (although neither is any other hypothesis, really), but we do actually have evidence of divine meaning, from mystics of all sorts. It's not clear to me how one goes about evaluating mystics, but there is something there. There are also plenty of stories of people interacting with the divine, as well as the "supernatural": saint stories, ghost encounters, NDEs, etc. There's a lot of noise there, probably more so than the mystics, especially given charlatans and people wanting to believe. But even the existence of a consistently strong desire for meaning on our part suggests that there is a decent possibility of something being there. Our desire might just be a wish for order in chaos, but it might also be an indication that we are longing for the divine meaning.

How does that work? Do they just let foreigners into their University? And does this get accepted in any western state?

>You are naive to speak so against absolutely anyone. Or a hypocrite.

You're the one speaking in absolute terms about Musk's motives and casting aspersions against the character of anyone who disagrees with you. Aggressive arrogance only works around here when you have credentials or evidence to back it up.

And the only difference between being politically motivated and having an agenda is that the latter is the means by which the former is actualized. Musk believing Twitter is infested with a "woke mind virus" is being politically motivated. Musk changing Twitter in ways that he believes will correct that is an agenda. It's quite obvious to anyone that Musk's operating of Twitter is in service to his political beliefs. He certainly isn't doing it to make money.

And, yes, he's also an egomaniac manchild who treats Twitter like his personal sandbox.
It's very difficult when you only have a wood or charcoal stove that needs to be fanned for 20 minutes at a constant rate or else the rice will burn. Which is why the electric rice cooker was such an amazing creation. It's in the article about the inventor of it.

As for today? Well, too hot on the stove or a phone call comes in, and poof, there goes all the water and the rice burns. If you're making rice 3 times a day, it's easier and safer to cook in a machine that guarantees perfection every time.
When I want to transfer currency units to entities which are not within range of any personal locomotion apparatus, I utilize a government service that transfers paper parcels anywhere in the country for a fixed rate. A few days later the receiver redeems the check for currency units deposited into their banking account.
But the post actually lines up with Barrett’s ideas rather than contradicting them; it explores how we often interpret facial expressions as a kind of language, shaped by culture and context, not as hardwired signs. It’s saying that while we might associate certain expressions with emotions, those associations aren’t universal—they’re flexible, just like Barrett describes.

So in the end, both the post and Barrett agree on the complexity here: facial expressions aren’t a one-size-fits-all code for emotions. Instead, they’re open to interpretation, and that interpretation depends on context, culture, and our own experiences.
