> Where is the proof?

von Neuman proved it for 2 players in his classic "Theory of Games and Economic Behavior": https://archive.org/details/in.ernet.dli.2015.215284/page/n3...

Nash proved it for n-players: https://pmc.ncbi.nlm.nih.gov/articles/PMC1063129/pdf/pnas015...

> "GTO" is only possible against perfect play to begin with

This is a very common misconception, probably because GTO is usually explained as the equilibrium reached by 2 perfect players.
The key insight of GTO is that you do not (and, perhaps, should not) adjust your strategy to what your opponent is doing. If you play the equilibrium strategy and they don't, you're guaranteed to make money.

> And I also never claimed exploitative strategies guarantee everything, for the same reason "GTO" doesn't either. It's a game of incomplete information.

I didn't say you did, I was just making my own independent argument as to why intuitive play is dangerous and people often end up deceiving themselves into thinking they're winning players.

> And, there are pros that have been winning for long amounts of time knowing zero about GTO theory.

Which is why I said that, IMO, 90% of pro players fundamentally misunderstand poker (and that's not even counting the losing players who think they're "pros".

Design thinking is a collection of techniques that have been professional-ized into a consulting practice. Hence the mystique.

What I appreciate about a good design thinking session is:

- It externalises the insides of peoples heads in a way that allows other participants to share that knowledge. Individual tacit knowledge becomes shared general knowledge.

- Knowledge elicited during the session is presented in a way that makes it actionable

A design thinking session is doomed to failure if it isn't comprised of:

- Domain experts

- Decision makers

- A facilitator who actually knows what they're doing

They don't care. Azure has a revenue higher than GCP, losing only to AWS. It's Microsoft's new baby, and they love it, no matter what you want to run there. Also, they're still the 4th largest company by market cap.

Honestly, only us nerds in Hacker News care about this kind of stuff :) (and that's why I love it here).

edit: also, the article cites OpenAI did adopt Azure Cosmos DB for new stuff they want to shard. Still shows how far you can take PostgreSQL though.

Is there any reason to believe there would be any? My understanding of PFAS is that they are used in the application of various coating like things (teflon originally, also since then waterproofing applications, paints, makeup, and firefighting foams)... none of which seem particularly related to making thermoplastics and pushing them through a nozzle into various shapes?

PoiZoN BBS Sysop chiming in. I ran the BBS on a free phone line I found in my childhood bedroom. I alerted the phone company and a tech spent a day trying to untangle it, but gave up at the end of his shift. He even stopped by to tell me it wouldn’t be fixed.

I didn’t know the phone number, so I bought a Caller ID box, hooked it to my home line, and phoned home. It wasn’t long before every BBS in town had a listing for it.

This just shows batteries shouldn't be the only storage technology, at least at high latitude. There needs to be a complementary long term storage technology with low capacity capex, even if its round trip efficiency is bad. Examples: green hydrogen, ultra low capex thermal storage.

To see the effect of including such, go to https://model.energy

Using a long term storage technology (in addition to wind/solar/batteries) can cut the cost in half at high latitudes.

Why would it only be a year of updates? Just go back to how it was 10 years ago when most software was a 1 time purchase and you got updates until the next major version, then maybe you'd only get bug fixes and security updates until your OS deprecated some API the app depended on.

The industry had arguably more innovative products than exist today and that business model worked totally fine until the platform gatekeepers and VCs invented SaaS because they decided they weren't making enough money and needed to do some rent seeking.

> Why would a country want to remain a manufactured-good export economy, rather than having the stronger position of a consumer economy that lives off the wealth of the rest of the world?

1) A consumer economy is not required to extract wealth from other countries.

2) A consumer economy is metastable by design:

(2a) It inherently requires the buy-in of other nations to want to export to you in the first place, which is not guaranteed.

(2b) The wealth of the consumer economy is primarily derived from salesmanship and not the product itself, which is also metastable.

3) Knowledge work is not barred to an export economy, and can similarly be performed there without having to become a consumer economy.

> Why grind away relentlessly in industries with tiny profit margins, when there are high-margin innovation-driven industries that your economy can advance to?

(Previous point (3) similarly applies here)

> Why stick with producing clothing, when you can move on to cars? Why stick with cars, when you can move on to chips? Why stay with chips, when you can move on to the next new technology that the entire world wants, but which only your economy can produce because it grew the industry from scratch and everybody is playing catch up?

1) None of these decisions are mutually exclusive. Why throw away the $10 you picked up just because you saw $100?

2) Establishment of a new industry is not assured. Failure can still occur, even when billions are thrown. (see Abu Dhabi & GlobalFoundries semiconductor fab venture)

2b) Not very new industrial move needs to be made. Tech leapfrogging can occur at a later date.

3) The demand for those """lower end""" products do not evaporate. Unless a sensible smartphone-like revolution comes for clothing / cars (i.e. The unification of multiple former products under a new product), the industry's products & demand will rarely change. The tastes will shift, but the fundamentals of the product & the industry will remain.

4-IMPORTANT) Margins are not obligated to trend towards zero, and can in fact increase as more people make the same mental conclusions as described and abandon their own industries, eventually leading to an oligopoly / monopoly scenario that is harder to retake back.

> Dictators love autarky because it gives them complete control of the population. Populations should not love autarky, because it makes them poor and robs them of wealth and opportunity.

Wealth does not inherently manifest from (the ether / nothing), and neither does opportunity. Even in the EU, wealth is derived from the decisions of the State to create / retain wealth.

Tool calls with middleware. If you deploy an agent into a production system - you design it to use a set of curated whitelisted of bespoke tool calls against services in your stack.

Also, You should never connect an agent directly to a sensitive database server or an order/fulfillment system, etc. Rather, you'd use "middleware proxy" to arbitrate the requests, consult with a policy engine, log processing context, etc before relaying the requests on to the target system.

Also consider subtleties in the threat model and types of attack vector. how many systems the agent(s) connect to concurrently. See the lethal trifecta

> close to the price of the underlying metal

Never? Never for plastics either. It seems like there's always going to be a lot of cost in shaping these materials through carefully controlled very high temperature environments. On the plastic side of things just the filament you feed to a printer is a multiple of the cost of the plastic feedstock that goes into making the filament.

You can send off models and get them 3d printed in metal today reasonably affordably today, reasonable as in "considering the time and expertise that go into making the model making a one off part like this isn't breaking the bank" not "competes with mass manufacturing on cost".

> Apple Pay: Card Icon Changes Address

This one is one of my pet peeves even outside of Apple Pay. My personal opinion is that almost all iconography is just reinventing the wheel. We already have a widely-accepted iconographic vocabulary already understood by a billion people: Chinese characters. The fact that English speakers can't read it is immaterial, because English speakers already can't read the icons we're already using. Using Chinese iconography in all languages will dramatically increase the legibility of the icons we use in apps.

(Or, we could just put regular text under the icon...)

... You haven't met Colombians. It could be just my extended family or it could be cultural; they love celebrating birthdays, including your birthday and theirs, and will actively and overtly tell you what they expect. In a strange way they're asking, it's a negotiation of wants and needs.

It could be just between family. I should ask my wife what's the go.

I'm not saying he did anything wrong. I'm saying I can see how Anthropic's automated systems might have flagged & banned the account b/c one of the heuristics they probably use is that there should be no short feedback loops where outputs of Claude are fed back into inputs. So basically Anthropic tracks all calls to their API & they have some heuristics for going through the history & then assigning scores based on what they think is "abusive" or "loopy".

Of course none of it is actually written anywhere so this guy just tripped the heuristics even though he wasn't doing anything "abusive" in any meaningful sense of the word.

Yeah this was my take. "Duh. Now so what?"

One thing this article points out is that the growth of settlements is unrealistic. they follow a linear path of constant expansion whereas real medieval villages were very stable in a sort of subsistence mode for centuries.

I mean... yeah. But it's not a simulator, right? It's also not a time capsule. Should we write a blog post about how these game villages never actually existed with the people depicted in the game? Or write a blog post about how medieval villages actually existed in 3D space and not pixels on the screen? These are all true things but who was misinformed about them?

I don’t care if “we” are more productive and I certainly don’t care what western economists think about pre-industrial agriculture. I care that the two billion people living in households dependent on subsistence farming have a better quality of life than they did before the internet or mobile phones, which they undeniably have. That much was obvious fifteen to twenty years ago when mobile networks were rolling out all over over Africa en masse and every village I visited on my continental roadtrip had at least one mobile phone that everybody shared to get weather forecasts and coordinate trips to the nearest market town.

Anyone in a developed country who bases their opinions on the effects of technology on their and their friends’ social media addictions is a complete fool. Life has gotten so much better for BILLIONS of people in the last few decades that it’s not even a remotely nuanced issue.

Part of replication is skeptical review. That's also part of the scientific method. If we're not doing thorough review and replication, we're not really doing science. It's a lot of faith in people incentivized to do sloppy or dishonest work.

Edit: I just read your article linked upthread. It was really good. I don't think we disagree except I say we need to attempt the steps of science wherever sensible and there's human/political problems trying to corrupt them. I try to seperately address those by changing hearts with the Gospel of Jesus Christ. (Cuz self-interest won't fix science.)

So, we need the replications. We also need to address whatever issues would pop up with them.

Yeah, but your dishwasher or washing machine isn't the big electricity eater.

Your car is. And honestly, you'd rather charge the car at night so that you don't blow a fuse when you're running the dishwasher, microwave, dryer, oven, induction stove and charging your car :)

I have never blown a fuse being getting an EV, and so far still only once.

But charging at night is preferable for that reason, and I couldn't care so long as it's ready by 7am.

Load shifting EVs is easy, and this moves a lot of load. It was never about moving all load.

OP here - thanks for sharing, didn't know that! I found a source (below) that confirms that Acme is the source of the smoked fish, and claims that Acme works with specific delis to make custom lox for each. So the Russ & Daughters version may still be specific to that shop, even though it's all made at Acme originally (and they do ship nationwide: https://russanddaughters.goldbelly.com/).

doesn't mean those posts should not exist.

that's a guy sharing his honest experience on his personal blog. you have the choice to simply not read the article. it was pretty obvious from the start what it would be, there was no click-baiting.

these posts also provide an honest pulse on reality. for this same reason i won't say your post "just creates negativity in the world for no good reason". your post gives some kind of feedback on what some real people think. my post is just meta+1 on this honestly.

Nice, but shouldn't the behaviour change be behind a config setting? And it's not clear what the intent of the change is. Implementing PING/PONG seems different from what you said you were trying to do. And it's section 1.8 of the OpenSSH [PROTOCOL] reference, not section 1.9.

But... before you think I'm trying to be negative... good on you. I wish you well. Getting crypto/security code into open source projects can be a slog as people frequently come out of the woodwork, so don't get discouraged.

And the more I think about this... there's plenty of examples out there about doing HTTP based reverse proxying, but essentially zero for SSH proxying, so if you do that, it would make a great blog post.

You'd be surprised how many Apple engineers are fixing many bugs, of this caliber, on a semi-regular basis.

That "Human Hours Wasted" is not just sitting there because engineers don't care about it, it's because there are many many other opportunities to save similar amounts of time. Crashes waste time, perf bugs waste time -- and security bugs are much worse.

The most egregious bug/s I've encountered in recent years is the utterly cursed tab management in iOS Safari.

A couple of times a year it will just nuke all my open tabs (450-500) and present me with a delightful blank screen. Before that it will mislabel the active tab group on and off before giving up entirely.

Quick action on my part stops the destruction syncing & I usually end up recovering them on my Mac & then save them as a tab group.

But literally just an hour ago, iOS Safari looked like it nuked ALL MY TAB GROUPS. Ugh. They were gone; swiping right led to the "New tab group" screen. Frantic backing up and a restart later, and the tab groups are back, as though the phone was like "just kidding!". FML. So much for that backup plan.

UI bugs are one thing, but how is that level of data loss acceptable in a modern operating system? Boggles the mind.

(And don't get me started on the UI track wreck that is the iOS-inspired/inflicted bookmark management on macOS Safari, where all Mac UI conventions went out the window for some reason.)

The time lost estimates here are comically implausible--if Apple bugs were wasting 32m person-years per year, with around 1.5b Apple product users total, this would imply that the average Apple product user loses 32m/1.5b ~= 2% of their life, or about 11 16-hour days, to Apple bugs. If that were happening to you you'd, uh, notice :)

It all depends on the key exchange mechanism (KEM) used at the start of the TLS session. Some KEM have a property called “perfect forward secrecy” (PFS) which means it’s not possible to decrypt the TLS session after the fact unless one of the nodes logs out the session key(s). Diffie Helman and ECDH are two KEM that provide a PFS guarantee.

I highly recommend the Fidelity CMA (Cash Management Account), it behaves mostly like a checking account but it autosweeps into SPAXX so you get the best of both worlds - your money is instantly accessible but you get the earnings of a money market account. I no longer bother with a HYSA.

It's not a bank account so you will still need a backup checking account if you need Zelle or similar, and it has no way to deposit cash - but the CMA has direct deposit, ACH transfer, debit card access, and check writing, so 95% of the time it does all you need.

I get some the appeal too but once you get a setup dialed in well and safely for ASA/ABS, theres rarely a reason to want to print either PLA or PETG.

Better ratio of weight to strength, far more durable parts for most jobs, and acetone smoothening opens up all sorts of doors to incredibly high quality prints without all the labor of sanding.

email2verify.com — Unlimited email verification (single + bulk)

Most email verification tools charge per credit and get expensive fast, especially for bulk checks. On top of that, most of them are not accurate and sometimes even guess validity of some emails.

email2verify.com offers unlimited single and bulk email verification with multi-layered testing of any email.

My focus is always on great user experiences in whatever products I built so far, hence would love to know your feedback and also if you are facing any issues while verifying.

I'm pretty sure Japanese are guessers (would love to hear counter examples)

To them, the etiquette is that if you ask you've put the other person in a bind. Even if they want to say no, they feel pressure to say yes. You putting then in that situation is considered bad. So, don't ask, at least not directly. You can say "Guess what, I'll be in town next week!" and see if out of the blue they offer a place to stay. But even then there is subtly of reading between the lines, of do they actually want you to stay or are they just being polite but hope you'll read between the lines and not take them up on the offer. Generally you're supposed to refuse "Naw, I couldn't possibly stay and get in your way" and then they can come back and say "No really, it'd be great" if they really want you to stay and you might have to do this dance once or twice more to really verify it's ok.

it depends on the medium. A flac will be distinguishable (for now); but put it out over low bandwidth media and you get https://youtube.com/shorts/dpScfg3how8 which, https://www.youtube.com/shorts/zi7BVqVzRx4 is real good and close to what that podcaster's voice sounded like when i made that clone!

i have several other examples from before my repeater ID voice clone. Newer voice models will have to wait till i recover my NAS tomorrow!

this is the newest one i have access to: Dick Powell voice clone off his Richard Diamond Persona: https://soundcloud.com/djoutcold/dick-powell-voice-clone-tes...

i was one-shotting voices years ago that were timbre/tonally identical to the reference voice; however the issue i had was inflection and subtlety. I find that female voices are much easier to clone, or at least it fools my brain into thinking so.

this model, if the results weren't too cherry picked, will be huge improvement!

Disclaimer: I am author of Marmot https://github.com/maxpert/marmot so I will sound extremely bias.

I have been asked multiple times on why I chose SQLite and not Turso. I've always responded people that I don't trust an open-source project once it's backed by a VC firm. I've moved away from Redis to Val-Key for same reason, and we have seen the Redis train-wreck in slow-mo. I hope at no point in future Turso ever ends up in that state, but chances are pretty high. At this point the "compatible with SQLite" has become a marketing term IMO, we all know how easy it is to break compatibility here or SQLite to break compatibility.

I get the frustration. I hope though that the opinion of the people who matter the most - i.e., your friends and family, and not random Internet strangers - will be based on who you are as a person, not on your identity as an American. Don't worry so much about the noise on social media, it's part of what got us into this mess in the first place.

At the same time, there are things you can do besides voting. Maybe you already know or do these things, but just putting it out there... You can call your representatives (and they might actually listen, if you're a Democrat in California), you can donate to candidates in other races if you have the means (there are probably going to be some pretty consequential senate races this year), you can join a protest (peacefully, and especially if you don't have any dependents).... And who knows, maybe none of these things will make a difference in the end, but I think the bottom line is that if you truly care about some of these things that are happening right now in the US, it's better to find ways to act on your convictions than to stay frustrated and fume online.

Just my 2 cents.

Doesn't matter: the types of people criticizing such a decision happens to also be the type of people who have zero compassion for the victims of crime. "Mercy to the guilty is cruelty to the innocent" and all that comes to mind.

Rehabilitation at all cost / dubious redemption is the subject of the satire movie "A clockwork orange".

HN shall upload and upvotes articles like these, implying inmates are suffering horrible injustice in red states. But same HN shall not upvote any article about a blonde woman ukrainian refugee getting slaughtered in the neck and dying while hearing the last words "take that white girl".

Poor criminal: he now has to go the prison's library to read and cannot receive books and magazines directly.

Such injustice.
