I agree strongly with the tiresome comment, and I am a bag holder and have been interested in monetary policy and economics my entire life - but not enough to read the same 10 comments over and over every day.

In answer to your question, technically no, but realistically yes.

Technically, BTC “transactions” can happen "on paper", the keys can be physically handed off to each other, etc (there are plenty of possible answers here that are all fairly vague and hand-wavey). There are many problems with this that make it wildly impractical though (see replies to this comment).

In reality, El Salvador (if I've understood correctly) was going to use a lightning "side-chain" for dramatically faster and cheaper transactions - this would require connecting to a known (and centralized) main service. I would guess though that this isn't exactly intended to replace their currency as a day-to-day usage, but rather for large transactions (like the down payment on real-estate) which is already an "internet-strictly-required" transaction, even in developing nations.

I hope that answers the question - if BTC was meant as a replacement for buying a can of coke, you'd be 100% correct that the internet infrastructure is nowhere near sufficient - but despite what the "I hate bitcoin so much my mouth is foaming" and the "my entire life depends on the price going up" crowds say, BTC is not being suggested as the only currency for El Salvador, just as "legal tender" as an alternative option for its citizens to store their wealth in a system that is not controlled by banks that are outside of El Salvador. Personally, I think it's quite nice that developing nations now have a lever they can use against, for example, the World Bank.
Just to latch onto the undiagnosed ADHD bit: Having it diagnosed formally may help, getting medicated for it might help, but... it's not a panacea. My girlfriend (diagnosed mid-30's and on slow release medication) describes it as a mood stabilizer moreso than a magic cure. Doesn't fix procrastination.

I tried it once (trying the medication is part of the diagnosis), I found myself switching tasks with Intent and being really focused on one thing at a time, vs my usual mode of "multitasking".
It can definitively happen, but I think more times than not the others are more readable.

To be honest this seems to be a familiarity thing
> but with reduce you need to know what arguments in a callback mean

If I didn't know for it would be mind boggling what those 3 things, separated by semicolons, are doing It doesn't look like anything in the usual language(s) they're implemented. It's the same with switch.

The only thing both of them have, for and switch, and helps, is that languages that offer it and aren't FP usually use the same *C* form across all, whereas reduce's args and the callback args vary a bit more between languages, and specially between mutable and immutable langs.

I still prefer most of the time the functional specific counterparts.

Nowhere in the linked site that I’ve been able to find does it explain clearly that iCloud backup undermines on-device encryption.

The point is that the deep compromises made inside iCloud Backup are hidden from the user and (at best) buried deep in technical documentation. So deep in fact that I can’t find any mention of it on that site at all.
Readability and maintainability matters far more.

And no - the edge cannot occur as it would require a file / whatever to have that size.

Reminds me of this site that was linked here a while ago: think it was https://perell.com/essay/coolest-things-2018/. Curated content can be better than aggregators like HN.

That said, there's a lot of low effort curated content as well, think buzzfeed and the like.
Workers productivity in this context means Workforce productivity, not to be confused with employee productivity.
https://en.m.wikipedia.org/wiki/Workforce_productivity

It's interesting that working on a two plus year product cycle does not add to productivity, at least not how it's used here.

So as an employee it would seem to be a better career move to always work on something that can be shipped within a year.
To borrow a definition from Andrei Konchalovsky, art is that which imparts feelings. If a game does that, it's art. Many "gamey" games don't, and this is perfectly fine.

Consider two games, Inside (a great art game) and Overwatch (a great "gamey" game). Inside is much less rich in terms of gameplay, but (in my subjective opinion) does much more with feelings. Overwatch, on the other hand, is enormously, ridiculously rich in terms of gameplay, but when you're actually playing it (as opposed to viewing the art), it's more of a dopamine binge.
Sure:

- consensus

- distributed computation

- statefulness

- peer to peer identity

- peer to peer reputation of nodes

- resistance against many classic failure modes (e.g. Sybil attacks)

- peer to peer source of truth (e.g. Namecoin/DNScoin)

- verifiable code execution (smart contracts)

- immutability/ tamper proof

- and (obviously) peer to peer payments

Granted, some of these overlap with each other, but the point still stands. The pearl clutching over cryptocurrency seems extremely inauthentic when you consider the vast sums of energy tech giants expend to target us with ads.

Yes, it's not an ideal solution on many respects.

I kind of get why we got here, as encodings were a quagmire for a long time, and coming to a real clean, everybody's happy solution with unicode looked completely unrealistic.

We now have way better compatibility, got to settle for one encoding in most cases, and the annoyances are for now somewhat manageable (if/when China opens more to the global net, it might be a different story). Installing fonts is still easier than adding encoding compatibilities.
That is truly sci-fi and awesome.
Not forever, they can only rent seek as long as they provide a compelling device to users. Too much rent seeking = fewer app developers = fewer compelled users.
Yeah, I'd much rather have something like

congruence_classes m l = map (\x -> ((x ==) . (`mod` m)) l) [0..m-1]

than

def congruence_classes(m, l):
sets = []
for i in range(m):
sets += [[]]
for v in l:
sets[v % m] += [v]
return sets

For-in is very neat and nice but it still takes two loops and mutation to get there. Simple things are sometimes better as one-line maps. Provability is higher on functional maps too.

Same one-liner in (slightly uglier) Python:

def congruent_sets(m, l):
return list(map(lambda x: list(filter(lambda v: v % m == x, l)), range(m)))
Oh I didn't know that! Thanks for pointing it out.

Interestingly enough, it's a rather bad article that goes for framing things in a certain light...like mentioning Prussia's copyright law from 1837 and then going on to say way later: "The market for scientific literature didn't collapse even as copyright law gradually became established in Germany in the 1840s." No precise date there...which is 1845, as I mentioned in another comment, where the "Deutsche Bund" extended their own copyright law which existed beforehand. Prussia's law is insofar worth mentioning as it was really modern and comprehensive for its time....which isn't acknowledged at all in the article. The way they used Prussia's law from 1837, they could have used another state's one where printing businesses had "copyright" (printing privileges) for two years if they used it (as an example), and that started in the late 15th century, instead. Or they could have used the French-style copyright laws introduced in some states in the early 1800s due to the French invasion. Of course, due to the plethora of states and the lack of an encompassing law which the "Deutsche Bund" had to establish first, one could just hop across a border and copy a work, thus rendering the copyright law of a state effectively useless. That's also the reason why I didn't bother mentioning it at all in my other comment but here it's relevant because the article writes: "Germany, on the other hand, didn't bother with the concept of copyright for a long time", right before mentioning Prussia's 1837 law which is just straight up nonsense.
Where exactly is contradiction?
The other two have lots of fancy things done to the mRNA itself, including pseudouridine substitutions, 3 and 5 prime untranslated regions, and a poly-a tail. The payload comes from the NIH, and is modified by them as well with proline insertions to stabilize the spike in the prefusion form. All current EUA vaccines in the US (BioNTech, Moderna, Jansen), plus NovaVax (code not delivered to the user in that case) use some form of the NIH payload, as far as I can tell.

Edit: I forgot about the proprietary mRNA delivery systems as well, I don't really know much about those.

Easy in the case of ransomware or any other cases where a victim has to pay Bitcoins. The entity who pays the ransom/whatever sends the money to a Bitcoin address. This money is immediately marked as "confiscated" in cooperating jurisdictions. That money will be mixed in a tumbler (operating in a non-cooperating jurisdiction) with other Bitcoins, which get the same treatment. Or exchanged for a different cryptocurrency in an exchange that facilitates money laundering, and all cryptocurrency that is traceable that goes through that exchange is immediately marked as "confiscated".

You can keep using Bitcoins in non-cooperating jurisdictions, sure. But they'll automatically be less valuable or worthless because you can't use them in many countries.

People with development experience in Bitcoin could implement this in a jiffy. Doesn't even take a government really, you could probably build a startup whose main thing is to provide this information. Then people/exchanges/etc. could decide on their own if these Bitcoins have value or not.
Fair enough but I can't see that as more harmful than any other energy production. El Salvador still does not generate enough power to serve all it's citizens, so they will be building more power plants regardless. Hopefully they can balance bitcoin mining in the off-peak hours, and not create new plants solely to support bitcoin mining.

But I fail to see how geothermal's environmental impact is problematic.
I don’t believe there is such a requirement. I suppose it depends how deep of an integration you’re imagining. At the no-tech level you can simply have crypto backed redeemable notes - like the old gold standard.

There are also things like M Pesa/MobileMoney which have half a billion users in sub Saharan Africa. Simply an account balance held by telcos, accessible from any GSM phone. It’s custodial but could easily swap in crypto and extend to the rest of the network if there was a movement to do so.

But even without all that, vanilla crypto transactions don’t really take much bandwidth. You do need a connection of some sort but just running a light client is not very demanding by any means.
That was an extremely rare event that has only happened once in the history of our planet when the solar system was young. It's incredibly unlikely to happen in future, it's even less likely to happen by the time we've moved to Mars because the sun has expanded enough to make earth like Venus anyway.

In the previous thread[0] a fair few had strong opinions about their right or need to sideload.

It does occur to me to wonder… If I launch a computer device that is ultra-secure, with a tightly-regulated sandbox, would they demand that I support less-secure services? Do they demand that all devices provide support for side-loading?

Am I to be denied the choice of a device made more secure by virtue of its review systems, sandboxes, and other limitations?

Some will say “well just don’t sideload and it’ll be the same,” disregarding that while I myself would abide by that rule, I can’t make the same claim for my mother, who manages to stumble her way into infinite computer trouble. Putting her on an iPad has been a godsend from my POV.

Here’s what I’d like to see: in exchange for store monopoly, a guarantee of security and a limitation on commission rates. Apple’s control over the APIs and developer tools makes me think code analysis can prevent a lot of shenanigans. Hold them to it, and let us have the option of using a secure platform.

Sound synthesis: mostly when I was playing with PD (Pure Data). Linear algebra comes up all the time in sampling theory.

Music composition: this is a bit more far fetched, but I always thought of composition as a combination of vectors which can vary semi-independently. We want to pick some plane through that vector space and move within the plane. For example, we can vary in harmonic complexity, melodic complexity, rhythmic complexity, dynamics, tempo. But it wouldn't make sense to do all at the same time. So we pick one plane, say harmonic complexity and dynamics, and move within that plane. This allows the listener to get used to the 'space' that is opened by the composition. We can then slowly add more vectors, to keep the interest.

A very visual representation of this is the trackpads that you can see on certain modular synthesizers. Often there is a complex setup, but the variables of the setup are reduced to two dimensions, which allows the composers to vary within this projected plane.

Piano tunings: well, basically you have a vector of 230 piano strings of which the overtones are all slightly out of tune. To tune a piano 'correctly', you need to minimise set of equations of strings and overtones (matrix).

A workaround idea of the "Attaching multiple IAM Roles to an EC2 instance": attach a single role which is allowed to assume all the roles that you need.

It's probably not a good model as that's an absolute giant as asteroids go. The one at the end of the Cretacous would have had 1/10000 or something of this one's mass, and we consider that a planet killer already. I think a 500km monster really is exceedingly unlikely, there are a lot less of those and getting hurled in our direction probably gets way harder, too, at that size. More realistic scenarios with smaller (city-scale) bolides would be absolutely devastating, too, but still way more survivable.
Ah, yes. This is a point I really should have made.

If you've been "bit" by a small cap on a circuit board, imagine one as big as an adult's fist. I don't recall the output of this thing but one needn't read the label to know that if I can't completely enclose this thing in my hands, it's probably not something one should...enclose in ones hands? It is also in a nice metal container that's probably under more pressure than it should be; mine were always bulging.

With board mounted caps, a lot of this stuff lands in the "leaving pizza out overnight" category. I've only had one (small one) truly explode[0] due to age/being defective; several that I blew up in electronics class when the teacher's head was turned, but hey. And about a flobbidy-gillion that bulge, you could lick the leads (that's sarcasm, don't actually do this).

Now, fan caps/mostors like this -- I've been bit by (a 400V cap that was "not dead yet") -- I don't know that I actually touched the leads so much as some hair on my exposed arm made contact (it's why I wear my long welding gloves!). ...There's that moment well after you've registered the burning sensation and smelled the hair that you say a prayer of thanks to God while panicking that the business end is not yet any safer than it was a second ago.

The (somewhat unsafe) procedure I used was: Cut the power, pop the fuses, pulled the wires in the order I had in my notes from last time (with thick welding gloves[0]), pre-cut electrical tape to cover the three leads (model has lots of distance, it's a big cap). The cap is connected by three wires, far from the rest of the electronics, easy to get to, easy to remove/re-secure the wiring, admittedly -- easy to get a little too comfortable.

Carefully handle those leads; hopefully goes without saying -- even if the cap isn't bulging -- avoid heat-based treatments (hot glues/heat shrink). I tape the hell out of the big ones. I've only had to personally handle a small number of these, but there's a TV repair shop in the area that does free electronics recycling. I told the puzzled 15 year old at the counter what it was, he looked puzzled, so I explained that it can explode like a hover-board battery and he shrugged. I guess...good enough.

[0] In a manner that might have been a fire hazard, and were it exposed, could have taken an eye out. In my case, a moderate "pop", a black spot on the board, smoke, and shrapnel throughout the small case.

Mature internet infrastructure? No. Only perhaps if you want a whole bunch of validating (full) nodes, and only then for the initial bootstrapping and the whole hassle of downloading the entire blockchain up to that point, but past that, even for non-custodial wallets (AKA your keys therefore your coins), broadcasting a transaction takes very little.

For context, I'm running a full node from Venezuela. The initial bootstrapping was... painful, but keeping up with the rest of the network doesn't take much.

I don't set out to only curate stories which don't reach the front page. That's just a side effect, not a criteria.

Also, sometimes a story reaches the front page after it appears in my newsletter because it got re-submitted. Correlation? Don't know.
Small nitpick, I just read half the page with a 50% opacity overlay on it, as the cookie pop-up shows up in the middle of the page, not the middle of my current screen, which can be caused by setting an absolute width against a relative parent, or setting position to fixed but then using percentages instead of vw / vh attributes in CSS...

As someone knee deep in the 'serverless' world, I am also interested in what exactly this does that couldn't be solved by any number of key / value stores, like Cloudflare offer.

Call me a cynic, but it feels like we are slightly going round in circles, like "we have found that adding a database to our database-less services is a great idea" (even if that database is in the cloud and distributed and therefore low management and high reliability)

But maybe I am just missing the point here. Still seems like an interesting product and I don't want to come off as dismissive or discouraging.

I mean, you presented the theory with no evidence that it happened. Your argument is basically that the united states could have done it, had motive to do it, and has a history of doing underhanded things in the past. Even if for the sake of argument i grant all of those things, its still not any more plausible than the official story. If you don't want people to call it a conspiracy theory, get some actual evidence that they actually did do it. Saying they could have done it and might have wanted to isn't enough.

There are countless ways for those countries to retaliate: war, terrorism, cyber attacks, disinformation campaigns, corporate or political espionage, releasing state secrets, stoking geopolitical tensions, creating anti-US coalitions, etc.

Not saying that punitive actions can’t be effective, but the US is still vulnerable to some forms of retaliation, especially if get initial action is as sudden and dramatic as the ones you describe.
