> "To this day," Bjork says, "most people think about forgetting as decay, that memories are like footprints in the sand that gradually fade away. But that has been disproved by a lot of research. The memory appears to be gone because you can't recall it, but we can prove that it's still there. For instance, you can still recognize a 'forgotten' item in a group. Yes, without continued use, things become inaccessible. But they are not gone."

This was quite eye opening to me when I first heard of it. Apparently, our long term memory is virtually limitless. You never truly lose something you once had learned well.

Another fact about memory that I found equally interesting: memory is not a "thing" but a process. When you recall something, you are actually reconstructing the memory from various factors associated with it, pretty much like how a paleontologist might reconstruct the image of a dinosaur from fossil remains.

> i can’s shake the feeling that callback passing and generator coroutines are a fad [...]

Callback passing and coroutines are well known techniques that's been around for a while. Generators are just coroutines that yield to their parent. I remember using these concepts in C and Tcl ~15 years ago[1] and they were well known then. According to wikipedia (citing Knuth), the term coroutine was coined in the late 50's by Conway.

Callback passing and coroutines suits some problems well. Sure there are situations where they do not fit and if people use a hammer for all of their problems they will create new ones. I wouldn't call it a fad, though the techniques may be a bit hyped up in some circles.

[1] I don't remember when Tcl got the coroutine package, that may have been later

Is it possible to use M3 without a retention downsampling policy? For example, to retain timeseries metrics at the 1 second resolution indefinitely for one or two days worth of data.

Edit: I was interested in M3 for this instead of just a time series DB because I’d also like to aggregate the metrics at lower resolutions and higher resolutions.

I have been to many bistros since moving to Paris in March. This bistro must be very, very different from others - unless the author is saying this just to reinforce their narrative and image of the bistro. Parisian waiters are notorious for being busy and hard to catch.

That being said, it's still a very nice and iconic part of Paris and a good place to socialize. With all the tourism I doubt that we'll see a mass-closing of bistros. Changes in society, consumer habits and demography will of course drive change, though.

Elon Musk Makes $82B Gambit to Silence Tesla Critics
I started working straight out of high school. Over the years I got a BE, ME and a PhD and paid my tuition fees from my earnings. For my PhD I published several papers in ACM and IEEE journals, all the programs I had written as open-source and a thesis.

Along the way I accumulated a great deal of expertise and experience. These days I get hired as a consultant and write reports on my findings, recommendations and often specifications for new systems (both hardware and software).

When you have knowledge and experience that people will pay for, then there is no incentive in giving it or my clients' expertise and knowledge for free.

I suppose you just get a license for one cpu core for your database servers and run them on 32-corevservers too?

The license is strange - but it is what Apple is selling.

And AFAIK the latest release is a "free" (gratis) download anyway - so you can't even claim you've paid for it.

I mean sure, you can ignore the license. Maybe Apple won't sue, but they might revoke your developer access, I loud account etc.

[ed: anyway, the thread started with a claim about "moral" obligation, I'm just pointing out that Apple is refusing to give or sell a valid license, so you're in breach of the license. I don't see how it's legally very different from an illegal copy of Microsoft Windows).]

Python is my language of first choice, but I must say that I am not that thrilled how this multithreading ended up. There are many tutorials about the topic promising to explain how it works, usually in the form of "simple introduction". But when one tries to implement something production-ready, with correct error handling etc., things starts to complicate pretty quickly; at least that was my experience. I don't want to accuse anyone specifically, but most of the tutorials I saw seems to portrait it in a way, that it looks easier than it actually is.

Ultimately, my company decided, that instead of fighting with asyncio, certain projects will switch to Go.
No not really, the algo might be slightly "better". But if you only want flashcards, go with Anki. I'd also recommend you make them yourself.
How i scrap/parse data from websites, and why?
Wasn't there a language where every call was async? Instead of async ... A/returing Future[A] it did/would return A from method calls.

If it didn't exist, one can imagine one.

A.x = 3 would be wrapped in A.map(_.x = 3) etc. So you write code that would be executed when you finally await a value. No more red/blue world. Would probably need coroutines instead of threads for executing.
Isn't that how Facebook got started: by creating networks based around schools? I don't see the big deal, especially if the school isn't developing new communication tools for students.

The ones that benefit the most from the welfare state are the ones that (theoretically) pay the most for it: the wealthy. Imagine if Gates/Jobs/Page/Bezos et al had to invest in 18 years of education and healthcare for every potential hire? They'd never get the employees they needed to strike gold.
I have a little function for generating some random characters

}
In the real-time operating window, some generators may have must-run characteristics. For instance, hydro with downstream flow requirements for fish habitat or agricultural use or nuclear without thermal bypass. It's easy to say 'let the operators deal with the operational complexity', but if you're going to need to that nuclear unit in 6 hours you can't tell them to pound sand and poison their reactor now. Furthermore, even if the energy from some conventional generators may not be needed, they may be required to run to provide grid ancillary services such as operating reserve (the ability to ramp up or down rapidly) or to avoid violating system operating limits due to physical constraints on the transmission system.

Since wind turbine generators will not experience or cause physical damage due to rapid curtailment, only commercial harm, in a scenario where the spot price is going to zero or negative (i.e. the marginal energy being produced is not valued by anyone), it can make operational sense to curtail them before higher emitting generators under certain conditions.

Keep in mind I'm speaking only to the real-time operating considerations (think a time horizon of 24 hours) not the larger generation planning perspective. The system should be planned in a way that minimizes the need for renewable curtailment, but that's a long-term goal that isn't accomplished yet. Operating on a strict zero-curtailment basis for wind turbine generators reduces system flexibility and maneuverability and results in costs for all ratepayers.

Yup. Let's forbid education for women. It'll definitely result in a better society for everyone.

Quality is more important than quantity. More educated people will produce better product and improve everyone's lives. Not saying that denying 50% of population a chance to live their lives as they want is plainly wrong and immoral.

You skipped the first part of the story: why was there a boycott?
Heh, this makes me think of this anti-viral startup idea I had - which I'm not going to make because it's... Anti-viral and thus not something I think I could pull off. Anyway, the idea was pretty funny: a meetup-like website where you'd sign in with e.g. Facebook, and then you could only see and attend meetups that none of your Facebook friends are attending. In other words: everybody goes to these meetups with the expectation of not knowing anybody and getting to know new people.

That said, I think there's only so many people interested in actually meeting new people, at least of a certain age, and even those who are, are only interested in getting to know a small amount of new people.

Still, I quite like the idea. I don't even think you need to group people based on interests (though of course the subject of a group allows people to self-select); just being open to meeting new people can probably go a long way.
This. The fact that they've closed so many interesting questions as off-topic is the primary reason I'll likely never contribute anything to SO.

The line which researchers here in Sweden define that a profession is gender segregated is if it has less than 40% of a single gender. It comes out to about 90% of the population, both men and women, work in gender segregated professions and only 10% work in the remaining gender equal professions which would include professional designers.

If we set the bar higher than a minimum of 40% then we are quickly going into single digit percent of the population. There is very few professions with an exact 50/50 ratio.

> Chronological is just one ordering. Why are you so attached to it?

This is a very deep question you’re asking, and I don’t know the answer. But, this boat only goes in one direction so let’s make the best of it.

But seriously, sure other sorting methods are useful. I would like to have many options, but I can’t think of a better default for this use case. Can you?

> ...as demonstrated by their engagement, prefer the algorithmic model.

You just don’t understand my point. Maybe read it again. I dunno. But ...

As demonstrated by their engagement, people prefer doing whatever their boss tells them to do.

As demonstrated by their engagement, people don’t actually like sex very much at all.
As someone who doesn't use WhatsApp in a country where everybody does: the primary use case appears to be group chat. If it was just a replacement for SMS, not having it would not be a problem - I could still text with people. However, I'm "missing out" on things because I can't be in some WhatsApp chat groups.

Hence the network.
”I give up... a failure”

You could also call it a partial success. Your A and B may help others write their C and D.

> but theptip writes below that heating water in residential and commercial settings might be better.

When I worked at Ørsted, we did this all the time. We had a huge electric kettle, which we used to produce district heating water.

But there are many more things you can do with surplus energy. You can make methane gas from pure CO2 and hydrogen when you apply electric power as a catalyst.

The methane can then be eaten by bacteria to provide protein powder to be used as supplements to feeding livestock.

Or, we can yank CO2 out of the atmosphere and store it as ethanol. I think this was discovered last year or so? Ethanol is a really good "battery", and it only discharges as much CO2 as was captured by the surplus energy used to make it, making it a clean fuel that only exhausts CO2 and sterile water.
"I am not rich enough to buy cheap stuff."
Very clever idea, very cool. I can't wait to try it.

If you're lurking, check out the examples on their website ... it's worth looking into. (I have no relationship with the company or product whatsoever other than being impressed).
Depends on the actual concrete. It will have lower thermal capacity per weight, but that may be offset with higher density. (The most common concrete would be worse than water with capacity being 1.3 (vs 4.2 in water) and density of 2400 kg/m3).
(I'll be honest that I didn't originally didn't read that the topic under discussion was modding of games. Passing off a game as your own is obviously not right, but that isn't the only topic under discussion here.)

Of course modding is not the same as Shakespeare. My point was that stories like those of Shakespeare would not have been possible with our modern notions of copyright. I do agree that many (but not all) examples of such work are just simply rip-offs of other people's work. On the other hand, does it make sense for any work to be untouchable for an essentially unlimited period of time?

So while you might argue that mods are all shameless copies of another person's work, I direct you to 'The Stanley Parable'[1] which was a mod of Half-Life 2. I think most people would argue that it is a creative work that is unique despite the fact that it re-uses assets from a copyrighted work. There are many counter-examples to the idea that the only way to have creative value in a game is to "draw your own monsters". Jim Sterling ran a contest where people were to come up with original works based on an overused Unity asset, and the winning entry was a game made entirely out of textures based on that asset[2]. Is that not a creative work?

I think that ultimately it's a disservice to argue that all such works should not be allowed because many examples of people building on previous work is lazy or a transparent rip-off. That the requirement for a creative work be a strict sense of originality (not to mention that you need to decide how do you define sufficient originality -- is "Harry Potter Told Using Pokemon" an original work?).

Zen of python
Happened to me last last year, an openssl upgrade broke many of my projects, and wasted a couple of days trying to fix it with no luck, had to resort to docker to get them working again(not a good DX).

I don't use Arch as my daily driver anymore, I've switched to NixOS(has its issues as well, but at least no rolling release model)
Using Hackintosh as my primary driver for 3 years. no Issues. For every 1 person having vocally shared their problems, there are 100s who keep quiet, because of its working fine.

Apple hardware also has problems, yet people use them as their primary computer all the time.

Of course, there is a slightly higher risk with Hackintosh than a proper apple computer. But if your computer uptime and data is very important, the solution is having a proper backup. Having apple hardware won't make things marginally better.
Another tip is to add mnemonics if possible. I wanted to learn Hiragana for fun, tried with flash cards and struggled for hours without progress (maybe got 25% right in the end).

Then I tried with the app Dr Moku that has mnemonics, took like 90 minutes until I started to get a perfect score.

Still takes spaced repetition to keep it in long term memory though.

Peaker gas plants running on gas imported from whom, Russia? At least Germany has the biggest gas sorage capacity in Europe.

https://www.ecfr.eu/article/commentary_europes_vulnerability...

A possibly better strategy would be to produce DME using excess capacity and convert diesel vehicle engines to DME. Then export both the cars, the fuel and the tech to produce the fuel locally. Maybe even use it as input for peaker gas plants and shipping fuel. Germany has all the resources necessary to establish and lead such a market. Plus they don't need to throw away decades of investment into diesel ICE R&D. See chapter 2.2 of this article.

I'd offer you one blindingly obvious explanation for why it's putrid: because it is a machine deciding which of my human relationships I should pay the most attention to.

Machines can't do that, silly. They can only promote hate speech with 100 comments and lolcat pictures with 100 likes. The only option is for them to take a back seat and present an ordering that is semantically meaningful to the human computer operating the tool -- the only one qualified to perform any kind of filtering and sorting.

"Relevance ranking" in social networks is a result of engineers having zero clue what applications they're working on, but that's just typical IT people divorced from reality for you. As you said, they find it acceptable because it's written in Angular v7 and uses ML and A/B testing revealed a 3.2% increase in clicks. The idea of the software industry helping real relationships is in general hilariously contradictory (but of course there are exceptions!)
Or instead, like most other advanced societies, we could stop trying to quantify higher education in purely personal economic return on investment grounds and consider an educated populace a public good.
Exactly! Teaching them the importance of privacy and the harm of social media would be a hundred times better than redirecting facebook.com to infowars.com. I would be pissed off if my parents had done that to me.
No, this is just business. Sony and Merlin have already sold all or parts of their shares, and are in the process of sharing the windfall with their labels. It's a pretty significant chunk of cash, so if Warner didn't do the same they would look incredibly bad.

Broader picture the majors want Spotify to succeed, because the alternative is having the business run by Apple and Google, who only have an ancillary interest in music.
"As demonstrated by engagement" - isn't really true. It's more "As demonstrated by count of time spent in the app". I believe that is true. But it's also a worse experience. Those two really seem to contradict each other, however, it's really quite nuanced.

I'd like to see mostly what my friends are up to. Instead of that, on Facebook at least, I mostly see viral videos from whatever groups I happen to be in. It is true that a lot of the time, those suck me into watching them. Technically that counts as "time spend in the app", but I also see that I'm wasting a lot of my time on crappy pointless videos and because of that I've actually not opened the app at all from time to time. In general, my attitude towards it has also changed - it used to be "ooh, exciting, let's see what's happened", now it's more like "meh, maybe this time there is something interesting, let's check, although probably not". Jaded is probably the correct description.
Hmm, I guess that the primary target audience for this would be people who currently already whip out regular expressions to run a search & replace in their text editor, rather than manually copying and pasting in the right spot the few times you need to make structured batch edits like this?
