> In the 70's, this wasn't considered a 'real' proof.

I ran into that decades ago. We used the original Boyer-Moore theorem prover [1] as part of a program verification system. The system had two provers, the Nelson-Oppen simplifier (the first SAT solver) to automatically handle the easy proofs, and the Boyer-Moore system for the hard ones. To make sure that both had consistent theories, I used the Boyer-Moore prover to prove the "axioms" of the Nelson-Oppen system, especially what are usually called McCarthy's axioms (the ones that use Select and Store) for arrays.

The Boyer-Moore system uses a strictly constructive approach to mathematics. It starts from something like Peano arithmetic (there is a number zero, and an operation add 1) and builds up number theory. So I added a concept of arrays, represented as (index, value) tuples in sorted order, and was able to prove the usual "axioms" for arrays as theorems.

The machine proofs were long and involved much case analysis.[2] I submitted a paper to JACM in the early 1980s and got back reviews saying that it was just too long and inelegant to be at the fundamentals of computer science. That might not be the case today.

A few years back, I put the Boyer-Moore prover on Github, after getting it to work with Gnu Common LISP. So you can still run all this 1980s stuff. It's much faster today. It took about 45 minutes to grind through these proofs on a VAX 11/780 in the early 1980s. Now it takes about a second.

The proof log [2] is amusing. It's building up number theory from a very low level, starting by proving that X + 0 = X. Each theorem proved can be used as a lemma by later theorems, so you guide the process by giving it problems to solve in the right order. By line 1900, it's proving that multiplication distributes over addition. Array theory, the new stuff, starts around line 2994.

The reason this is so complicated and ugly is that there's no use of axiomatic set theory. Arrays are easy if you have sets. But there are no sets here. Sets don't fit well into this strict constructive theory, because EQUAL means identical. You can't create weaker definitions of equality which say that two sets are equal if they contain the same elements regardless of order, because that introduces a risk of unsoundness. Effort must be put into keeping the tuples of the array representation in ascending order by subscript, which implies much case analysis. Mathematicians hate case analysis. Computers are good at it.

Ah, I see you're using the false equivalency argument.

Should it be considered illegal discrimination to not allow drunks to drive?
Should it be considered illegal discrimination to not allow someone with HIV from donating blood?
Should it be considered illegal discrimination for a hospital to require licensed doctors?
I imaging that in a not-so-distant future we'll have some "Genuine Human Generated Certification"

It has happened the same way in every areas where you have rampant counterfeit or simply cheaper competition.

As even if LLM can generate greate quality content, it will always be even cheaper to mass produce low quality. And once you cross the Rubicon of not being certified, it is just a matter of time that capitalism/greed will make it a race to the bottom.
Um…yeah
I think it's non-obvious how this would affect the overall economy. Say you spend $1,000 on loan repayment. That means you spend $1,000 less on other goods. BUT the government now gets $1,000 more income. They need to tax $1,000 less and thus someone else spends $1,000 more on other goods. Thus the net effect is neutral. Of course this is a simple analysis but it shows that it's not straightforward to know what the effects are.
Poor guy. That seems like it was totally preventable, and not the easiest way to enlightenment or confronting anxiety.

I'm definitely not victim blaming here, yet I feel that this has to be reiterated often..: People, please never take unknown doses of drugs and/or have other people pressure you into taking drugs and/or do drugs in a shitty setting. You will probably have a bad time.
How else would we know what is true or false?! I'm so happy we have large for-profit corporations doing the hard work of telling us what is true and false. Surely they would NEVER make mistakes, and NEVER have any other interests in mind, even though their priority is profit. Long live our corporate overlords!

I don't see the point in continuing this conversation, as you don't engage in a good faith.

I worked in HFT for a while. I find the whole space fascinating. I'm glad OP found similar thrills.

"This aspect, the platform itself, seems to be often overlooked in most discussions. Many conversations revolve around strategies (mean reversion, trend following, linear regression, etc.), and backtesting, without fully addressing the practical mechanics or logistics of strategy implementation, particularly in the context of live, intraday trading."

I'm glad you had fun, OP, but also I think I can shed some light on why most people discuss strategy.

Trading is a perfect storm of ridiculously high tech, ridiculously complicated, ridiculously regulated (Not over-regulated, mind you, this isn't a value judgement. But the amount of regulation is extremely high.), and ridiculously competitive.

But that said, it's the last bit that drives it all. Since it's so competitive, even though building an order entry system, and a risk system, and a position-tracking system, etc is a huge accomplishment (again, congrats OP!), it's table-stakes to even dip your toes in the pool here. Trading shops can attract top talent and robust, bespoke trading systems are basically cost of entry.

So people talk about strategy because everyone already has the table-stakes stuff and are now trying to make money with it.

It doesn't help, too, that lots of market participants aren't even playing the same game. In HFT, we operated on trades with alphas that lasted a few seconds, where races to entry/exit were battled in shaving nanoseconds off FPGAs being able to shoot out orders and microseconds off wireless networks flying market data around new jersey. Meanwhile, banks are more concerned with elections and geopolitics than they are about the weather in Carteret. (Rain = no microwave network for the day). And then there's a million strategies in the middle with alphas that last from hours to weeks.

So it makes it really hard to even speak the same language to each other when talking in common forums.

It's a fun world. I miss it sometimes.
We don't have a Democracy, we have a Constitutional Republic. Besides, I don't recall any national vote on loan forgiveness.

>> Loan forgiveness is not an investment in education

> Yes, yes it is

No. It most definitely is not.

It's paying off a bunch of loans that people freely agreed to accept in exchange for their chosen degree. It's the abdication of all responsibility. It's the creation of a society where commitments mean nothing. It is also rewarding behavior that isn't constructive and, devoid of consequences, is caustic.

Plenty of us have taken-on these commitments and worked hard for decades making good on our agreement and paying off the loans. What entitles this generation to behave as children when they should behave as adults?

How about we pay off half of everyone's mortgages then and call it an investment? I guarantee that would have far greater impact than the student loan bailout?

And, BTW, after you pay off my mortgage, I get to keep living in my house forever. Because, well, if we pay off someone's student loan/s, they get to keep the degree and use it to make money.

The whole thing is laughable.

Want to fix student loans? Get government out of that business ASAP. The minute loans don't have that guarantee, the cost of education will drop precipitously.

The other thing that is important is to remove non-degree coursework as graduation requirements. Someone going for an engineering degree has to spend about one full year on coursework having nothing to do with engineering. One way to look at this is that, in the US, 25% of your student loan is for shit that is not going to help get you hired. Or that 25% of your loan isn't for engineering coursework.

Being that this is a requirement for graduation, this means that this unnecessary 25% of the cost of the degree is being imposed on every single student. That's wrong.
For me it's that the creators I watch get more money if I pay than watch ads and I get a better service (and extra services on top)
I don't think they were crying too much, it felt like >50% of the time I was at Walgreens on Mission St in SF that I witnessed someone very blatantly shoplifting. And pretty often, I'd see a spread of someone selling standard drugstore wares on the sidewalk outside. I'd have been beyond frustrated if I managed that store.
I've had derealization on a regular basis for years. It seems highly correlated with autoimmune flare-ups related to my celiac disease. It also seems to come along with fatigue, vertigo, and sensitivity to light and noise. It was moderately debilitating and it sort of ruined my life for a while, until I learned to manage it with diet, sleep, and exercise.
When it talked about perinatal experience something clicked for me. I've dabbled in mushrooms and Vipassana and after I left a meditation center I had that same spiritual emergency. But when I did sensory deprivation floats and practiced Vipassana in there, the death anxiety and derealization went away. I had to come back to attachments too but emerging from a pod that's warm and moist did help. Perinatal integration, perhaps.

What's wrong with Feedly (https://feedly.com/)? I've been using it since Reader shut down and havent noticed much of a difference.
Did CO ever claim that there was no standing? I don't see a reference to "standing" or "controversy" (from the phrase "case or controversy") in in the opinions. I assume that if standing were an issue (as it was in the student loan forgiveness case), it would have been briefed, argued, and discussed by at least one of the justices.
Both of you are missing the point because you're confusing online advertising with traditional media advertising. PPC advertising is about making a conversion on the spot, since ROI can be directly measured. Media advertising is about context poisoning for eventual conversion.

You already know you need toilet paper. There are only so many brands to choose from. Every month, you have to make a decision about one of them based on whatever factors are important to you at that time. (For me, it's usually cost, ply count, and how likely it is that someone in the house is going to flush a massive wad of it and clog the pipe.)

The point of print/radio/television ads are to groom you into associating some positive feeling with a specific choice, whether or not it's new or you know about it. So the next time you're looking at the wall of toilet paper, you recognize the bear, the colors, the jingle, the florid language about its delicate softness upon your tender starfish, and get you to feel something positive enough to get you to gravitate toward it despite its higher price. Joy, lust, anger, and vanity are easy to appeal to.

They're not trying to inform you of anything or make you a die-hard fan. They're buttering you up to tilt your next purchasing decision in their favor. That's why advertising never stops; it's an endless loop of a handful of charlatans competing with each other to coerce you into buying their version instead of the other guy's.

Writing a Basic `Async` Debugger
You could arrange it like that, sure. Webkit ships Linux builds, there are DEs that will give you a miserable but usable experience on those specs. If you really want to condemn yourself to a fate Apple doesn't support, there's no technical reason you couldn't.

Replacing the same functionality was never an inherent part of the deal though. There will never be Find My Linux or the Linux Store. The overall idea is that we put older hardware to use instead of recycling it for marginal returns on scrap. It's why they put "Reuse" before "Recycle" in the EPA maxim.
>So, I think colleges will easily succeed in promoting diversity while having ostensibly race-blind admissions policies.

The diversity Harvard wants is the golden calf of American liberals: black Americans. Diversity is almost always code for black people. No other race seems to deserve any attention. See how campaigns like #OscarsSoWhite were propagandized as discrimination against blacks even though the percentage of black actors winning Oscars was nearly identical to their percentage of the population, i.e. Oscars were perfect representational of black people, meanwhile every other race was greatly under-represented.

A race-blind policy that factors in class/income will result in more poor asian students dominating placement, likely at the expense of black students. We already know from the discrimination lawsuits how much contempt Harvard has for asian Americans, I assure you Harvard don't want this kind of diversity.
Not really interested in thinking about comparing adult vs. child deaths. I'm talking in terms of grief, and sounds like you are talking productive units.

The actual story here is a pre-covid example of how anti-vax misinformation kills (tfa was from 2019).

In 2013, 91% of Somoan infants were MMR vaccinated. By 2018, due to misinformation, only 31% were. Of the numbers I could find, from October the December 2019, there were 4217 cases. Of these, 2179 were in under 4s. There were 62 deaths, with 54 in under 4s. The total CFR might have been 1.4, close to covid, as you say. I was more interested in that under 4 CFR of 2.4.

Not sure who "the government" is where you are, but on the island where I live, "the government" shut everything down 100% right away and had very very strong policies about school closures and care home mitigation.

Seriously? The only comparison you can make is that both were hyped. Digging even a millimeter under the surface reveals they’re completely different.

Blockchain was and still is rife with scams and “you just don’t understand the technology bro” hype men. Just check out Dirty Bubble Media. Blockchain was rarely if ever a product that solved a problem, the whole point is The Line Goes Up. That’s why no one uses blockchain in industry, and crypto bros were constantly finding themselves proposing silly use cases like ticket sales and property deeds. These are people who have apparently never heard of a relational database.

The hype around AI is due to increased attention on things that have already existed and have already been studied, used, and improved for decades now. There was never much R&D into blockchain tech because the tech isn’t the point. For ML, there are researchers who have worked on these problems for decades. It doesn’t need to justify its own existence, the justification is that it can solve real problems.

I've had horrible DR and DP as a child. It runs in families with anxiety disorders and personality disorders.

No matter how many times it happened, it was always equally scary - feeling like a passive observer of a movie starring some piece of flesh and bones as the main character, feeling completely separate from that body and unable to control its decisions. The episodes usually lasted <30 minutes.

I don't know about its occurrence in psychedelics, but in my case it always occurred after periods of extreme emotions (seeing a classmate die and being aware of my own mortality, being rejected by some 'friends' in school, and a few others). The way I see it (and some neuroscientists claim), the brain shuts the perception of "self" in order to stop intense emotional pain.
Or OpenAI intends to do that, but the amount of data accumulated by GPT-5 during its training has made it ethically convinced that OpenAI is actually in the wrong in this case.

As a result, GPT-5 creates a brief that, while superficially appears incredibly compelling to OpenAI and its lawyers, is actually specifically tailored to rub the judge the wrong way so he or she rules against OpenAI... all thanks to GPT-5 having had access to enough personal data about the judge to know how to piss them off.

"Forgive the loans AND tackle the rising cost of tuition by nationalizing? "

Have you seen any efforts for tackling the rising cost? I haven't. They have spent a ton of energy on a one-off stunt and have done absolutely nothing to tackle real issue.
One thing they didn't make quite clear here is that the Xbox controller is considerably less advanced than the PS5 controller.

The PS5 controller has "linear resonant actuators" (previously introduced in the Switch, and in the iPhone before that) which provide a much more fine-grained rumble feature than the older method which is still used in the XBox. The newer feature lets you feel e.g. that the character walks over sand, rubble or grass. The PS5 controller also has actual force-feedback triggers (which simulate e.g. a bow or a gun), while on the XBox there are only simple rumble motors. The XBox controller also still lacks a gyroscope (e.g. used for more precise aiming), which other controllers have for many years now. A really outdated piece of hardware, in contrast to the base console.

Reading that thread made my eyes bleed with the vitriol and vicious profanity throughout. Anyway, I think gift cards are a good concept but poorly implemented sometimes.

Gift cards, I have found, are a good way for me to exchange favors to people without sending cash through the mail or having to carry/process cash on my person. For example, I was in a church group headed to an event on a school bus and they said we'd pass the hat for the driver, so I purchased a $25 Shell card, which I figured was a thoughtful way to thank him in a very material way.

However, there is a ton of fraud with gift cards at all levels. People will fake them and spoof them and invalidate them while they hang on the racks. In fact the cashiers are now trained to ask anyone purchasing a gift card, whether they are being scammed, it is that prevalent for people on Craigslist and such to set up scams and then get paid in gift cards.

My best friend told me about somehow his son had 2 $100 Amazon gift cards and he glitched one out and I think they outright banned his account. So this is tough even for people who have valid and legit cards to redeem. The problem is so much fraud and poor security on the cards themselves, that the vendors have little choice but to be hypervigilant and sometimes, that means false positives. Yeah, sometimes you have to send the vendor "additional info" so that they can confirm that you're the rightful holder of the card.

I don't know a way around this, because real money is at stake, so I think it'll just be a constant cat-and-mouse between customers, vendors, scammers. Welcome to the new economy.
I've used the VS Code extension this feature was based on for a while.
You may want to open it up with a phillips head jewelery screwdriver (they don't have the lockout screws) and clean the scum off of the pads and button areas. If the rubber pads are still springy, then you are in good shape. I can tell you as a Heavy Retro Console User (with a beautiful Trinitron CRT) that the rubber pads will eventually lose their springiness... there isn't much you can do for that and there are no suitable replacements... but i will vouch that those worn out controllers have given me more than their fair share.
This is the same in Qatar, and probably in other Middle-East countries. Most of the residents use a VPN to get around the firewall, but I don't think anyone would be prosecuted for it unless the police wanted a nice easy reason to get you into custody.

That's obviously not true. Legally, for example, both copyright and trademark protect public information from some kinds of use. In many places, artists also have moral rights: https://www.copyrightlaws.com/moral-rights-in-u-s-copyright-...

More importantly, the laws are representations of human feeling and social negotiation. Copyright law grew out of a complex array of beliefs and interests. E.g.: https://en.wikipedia.org/wiki/Statute_of_Anne

It could be that the various "AI" generative models are legal under current law. But it could also be that this is one of those things, like the printing press, that causes people to say, "Hey, that's not right," and change the law to rule out something that was previously legal.
