off-policy, offline, generative experience replay: these are all efficient ways to maximize our learning with finite experiences to learn from. for example, its hard to learn from rare experiences, and dangerous to learn from very hazardous situations you'd not want to be in.

However, as you pointed out, generative experience replay runs the risk of learning from counterfactual or impossible experiences. To mitigate this risk, we need a discriminator network, not only to distinguish dream from reality but to judge their plausibility (e.g. flying by flapping wings vs dreaming you took a vacation in Tahiti that you never took vs dreaming about forgetting to do your homework).
Definitely. I think a lot of deja vu and deja reve moments are actually these simulations happening at night.
A professional management class is a menace. Managers with experience in the domain they’re managing are key. Engineers-evolved-into-managers should lead engineering firms, etc. If you don’t understand what your underlying business is, you’re doomed to fail. Likewise, businesses should be predicated on selling products, not on boosting stock prices. There are at least two very wrong things: the Jack Welch-ification of companies, and professional MBAs.

I read the design pattern book a long time ago and it was interesting, but it was more of an introduction to the topic. An experienced engineer can get the same content from Wikipedia, you’ll only miss the funny pictures and the "tutorial format." I could recommend the books to a beginner though especially at that price.

When I started, I preferred books like those ones because there was too many tutorials all over the place, and choosing was a bit confusing. I guess I would buy that if I was a beginner again.

Wanting to collect a pension is NOT a wrong reason. It is a very legitimate reason for any government worker. I'd even bet it's inversely correlated with wanting to abuse power.

Moreover, the abuse of power looks to develop over time, learning it from other abusive cops, and going further. It is a cycle of abuse taught from senior to junior. Even if the police represent the community or are conscripted, they still can learn such abusive behavior.

The solution can be for all teams to be new, to not pass bad cultural knowledge from the old team to the new team.
Yeah but when you make a game, you have a game. Something you can share.

> a community based approach might look like

The reason I'm a fan of these (albeit they are far from perfect[0]) is because it both creates some humanization as well as some social accountability.

I think some of the problems are related to the fact that parts of society don't scale well (though some do). As population grows, so does anonymity. But a powerful tool to fight abuse of authority is by decreasing anonymity, as this creates a social pressure. There are disadvantages to cops being biased towards their communities, but I think this is better than the bias of indifference. We're dealing with humans, and the direction in which we should _error_ should *always* be on the side of compassion.

Generalize over their training data—they cannot generalize out of distribution. If they could, they would have already solved most human problems. So no, they do not generalize on unseen text. They will produce what is most statistically probable based on their training data.

> I didn’t say it’s stupid.

You're claiming that the main reason most people don't switch to Linux is some sort of deficiency of judgment rather than anything practical, and that's not true and it's never been true.

You dismissed the costs of getting used to a new OS right off the bat, and that's a real thing. In my link that you dismissed, the first sentence ("while Windows is very hostile ... to its users, it's rarely broken or buggy") is relevant to most users. Professionals may have trouble getting their apps to work, gaming has gotten better but still has the same problem. If user literally only cares about running a web browser, then yeah, Linux would be fine; but Windows is already fine, so why bother switching?

I like Linux. I've used it at home and professionally. I'm a huge fan of FOSS principles, and I think it would be better for everyone if more people used open systems. But Windows works well enough to satisfy most people, and they're not going to change purely for ideological reasons. Maybe it'd be a better world if they did! But it's not reasonable to expect them to, or to cast that as a failure of judgment.

Correct, why would the uk government ever lie?

https://www.computerweekly.com/feature/Post-Office-Horizon-s...

“The Post Office was determined to keep a lid on the Horizon problems. To do this, it instructed staff in its call centre, which was the first contact point for subpostmasters having problems, to tell callers they were the only ones experiencing problems.

It went further than this by using its legal teams and deep pockets to defend itself against accusations, in court if necessary. It bragged about stopping subpostmasters from “jumping on the Horizon bashing bandwagon” when it silenced them. It also lied to journalists, politicians and anybody else who questioned the robustness of the Horizon system.”

It's basically meaningless. If you ban the "Nazi party" and then someone comes and says they're a member of the Social Nationalists party which is totally different even though it shares a lot of the same policies, now you have to decide which policies are banned. And we're back to politicians are never allowed to censor their opponents etc.

I believe this paper shows that a part of the mouse brain responsible for telling muscles how to move when orienting also correlates with direction specific firings of neurons that are likely responsible for tracking the animal’s orientation and this occurs both while the mouse is awake and asleep. This updating of heading while asleep is considered a simulation. They take steps to experimentally show that this relationship exists and is likely causal.

This paper doesn’t show that simulation is the purpose of REM (though it may be) however they do go on to speculate that the simulation that is occurring could be used to improve the brain’s predictive models of movement actions and their outcomes without needing to move the muscles.

It is thus conceivable that the internal model that coordinates activity between SC and ADN observed during REM sleep may be at work also in the awake animal. This would allow the brain to predict shifts in head direction following the issuing of a motor command in the SC, before the motor command is executed and thus have a real time estimate of heading rather than depending on the necessarily delayed sensory feedback from the vestibular canals. … In the absence of error signals, these internal models are free to unfold and may represent the building blocks of the brain’s generative activity during REM or REM-like sleep in humans and animals.
Hey, me too! I populated the markov chain with the text of my Twitter feed with a recency bias and generated tweets based on that so it stayed topical.

The account sat unused after Twitter locked down their API, and at some point got hacked without me noticing. It had been taken over by a crypto scammer, and the account got banned.

Trying to get it back was fruitless, Twitter/X's support is entirely useless.
This argument would be coherent if cybercoins were illegal, which they are not.
I don't think we should blame the victim. Tech is insanely complex and some scams are so sophisticated now that if you're not switched on all the time you might get caught. The vector here seems to be an app posing as something trustworthy. Or what she claims as an app riding the reputation of Google. But to me its the same issue underlying phishing: impersonation.

Is impersonation fundamentally unpatchable? How does one ever really 'know for certain' that an app, website, etc, is legit? Could this be fixed, once-and-for-all, with something like a hardware device issued to all citizens with early education around scams? Or would scammers still find ways around it with things like misspellings, subtle details in presentation, or what-ever have you.

Scales poorly — any oil well has a particular debit, naturally limited. So will this.

The conflict of interest is real. This is why I expect the same companies that produce the CO₂ to process it into fuel. Say, steelmakers need a lot of pure oxygen, this is why they sell the liquid nitrogen they produce along the way. Similarly they extract and sell a number of metals that occur in the input ores in low concentrations and are not worth mining by themselves.

Regarding Sahara, the things are sadly as you described. But large industries are usually in politically more stable areas.

I think the argument for using the line is, there is no reason in the moment not to try everything you can, no matter where you are, and you adjust based on the situation. If you’re in a place that doesn’t respect the rule of law ALL THE TIME, sure, don’t. Is the US(I will assume you’re US-based) that right now? I think your answer to that question == whether you feel the tactic is viable.

Yeah, on top of which you have to add 3 times/week 1 hours of weight liftings and 2-3 times week 30 minutes of stretching

Also 43 minutes of HIIT sounds like a nightmare. I do 30 minutes HIIT and I'm completely spent afterwards, there is no way to reach 43 minutes.

Also with 7 days/week of 43 minutes a day + weight lifting your body will be overtrained so injuries will kick in.

Obviously it's a bit different if you do ONLY vigorous training, but then you lose all the benefits of weight lifting and stretching.

Seconded. I'm loving the Zed experience, but having Javascript features provided by the TS language server gives a really bad experience; if I fat-finger a bracket then I get a bunch of TS errors about missing TS stuff littering the code, even though I'm not writing TS.

It's not a deal-breaker, but it is really annoying - I have to find the problem myself with no assistance from the language server. In fact, with hindrance from the language server because it's littering the code with completely spurious warnings of irrelevant "errors" that aren't.

I haven't tried coding in TS on Zed, so I can't comment on how the actual TS experience is.

I get what you're saying, and appreciate your understanding. I was also sleep deprived, alone, and didn't know what I was doing so may have done the wrong thing.

I and agree that much of the advice to parents is just nonsense- and a lot of it flip-flops every few years, and is sold to parents using terror, saying your child will die or be permanently harmed if you don't do every little thing you're told. It really can help to look at your individual situation and apply some common sense. The terror itself is more harmful than the advice helpful.

I also agree that it's fine to let a kid cry for a while when they had everything they need already and the parents need a break, but I don't think it's evolutionary or culturally normal to let a kid scream all night long alone. Traditionally, people would be in small groups with a lot of caretakers and would trade off rocking or holding a baby. Humans are hard-wired to be extra responsive to, and annoyed by crying: without a big modern insulated house you could not sleep when your baby is crying. Breastfeeding women get a milk letdown reflex when they hear their baby cry, etc. I'm pretty sure I could feel my stress hormones slowly climb as crying went on, motivating me to do something.

This is yet another of those flip-flopping advice things: once they told people if you comfort a crying baby it will make them soft, weak, and dependent. Now they say it will emotionally traumatize them if you don't, and they will develop attachment and social problems. Both ideas are terrifying to parents, and when they hear them will work hard to do what they are told.

Ask HN: How can I practice designing data structures well?
Linus Torvalds said:
"Bad programmers worry about the code. Good programmers worry about data structures and their relationships."

I want to improve my ability to design systems well. And I want to work towards building things with Linus' mindset.

When I work on a problem, I try my best to design it well ahead of time. But I typically don't have a good grasp of the entire system until after I have mostly implemented it. The nuances of the system are not clear until I have implemented it.

What are some techniques you use to understand a system before you build it? What are some good books that outline those techniques? Or is this a skill that one can only gain through trial and error or experience building systems?
How did you conclude they were intentionally obscuring population density? How did you conclude population density, for that matter?

Having spent the last four-ish years living in "the boonies", I am generally unimpressed by how people from urban areas talk and think about rural areas and the people that live here. City folks don't know what's happening out here, and it's often because they don't care to, and it shows.

Pop culture is certainly a good source of trustworthy information. Let's quote sex pistols next.
My personal opinion? It seems moderately unlikely that a player as strong as Kasparov, who could have played the entire game against you blindfolded, would have been adversely affected by this. Most strong players' personal chessboards have no coordinates written on them at all. (Mine certainly don't, and I'm not even strong. Identifying squares is just trivial.)

He probably just wasn't putting much mental energy into your game, as he had other simultaneous games to worry about, and then a move you made perhaps caught him by surprise in some way.

(It also seems unlikely coming from Kasparov specifically - he has historically raised quite a fuss, even when on camera, when simul exhibitions were not conducted to his standards. If the board bothered him, I think he would have had it flipped.)

Wow, reading this now very old discussion makes me cringe a little bit when I see dingers like these:

> If you think it is easy, VLC is open-source: you are welcome to provide the easy patch. Somehow, I won't be holding my breath.

> If it's so easy, why are you not doing it? Talk is cheap.

> I'll be waiting for your patch. Surely you're not as lazy and incompetent as the existing volunteer developers.

> And I don't take moral lesson from an hypocrit who feels like they can demand work from "toxic" volunteers and even state that they are not there to do any actual work.

There are so many (passive-)aggressive comments in that discussion. This is the primary reason why I never get involved with open source projects any more. The discussions are so toxic. I always wind up feeling terrible about myself after "trying to help" an open source project by reporting bugs or submitting patches to fix bugs.
