The article points out that most extinctions happen on islands which are tiny compared to the world, and that it's mostly over because we've finished importing rats/etc to those islands and started protecting them. It might be a large number of species recently gone extinct but it's a small number of individuals and they're the least important ones because they're not part of the global ecosystem so nothing in the rest of the world depends on them.

I think it is referring to the fact that it is ubiquitous to leave some amount of reserve so that the battery is never fully charged (100% SoC) or discharged (0% SoC). This formulation is capable of going the full 0-100%, while most formulations will last significantly longer if they don't do that.[1] In that graph, charging to 75% and discharging to 25% gives you about 3x more life than from 25%-100%.

NB that most li-ion cells are rated for 300-1000 cycles at 100% Depth of Discharge. Reducing the DoD to 90% or 80% will get you thousands or tens of thousands of cycles, although it is abnormal to actually measure that long. A charge-discharge cycle at .1 C (the former standard) takes 20 hours.

Dungeon Master Skills You Can Bring to Work #5 – Adaptation
The money to pay people comes from loans, which are thousands of people hoping they make more money in the future to pay salaries today. If salaries were higher, tuition would be even more difficult and raise the loans even more.

Really universities need to find ways to capitalize on their knowledge base to help pay salaries. They also need to reduce overhead... Many schools have several disjoined IT and sometimes HR departments.
When I worked as a DJ back in the 1990s I observed that if a 12” or LP skipped you could momentarily turn off the tone arm bias and the extra inward force would usually ride over the scratch as of it wasn’t there. With CDs you were toast.

If a CD skipped then there was nothing you could do except stick another on ASAP.

CDs are a very fragile medium. Especially so if you scratch the top printed surface.

These days you’d do it all off a laptop with no moving parts and no skipping.

No, but it is common to treat them as if they were. It depends on the chemistry as some are worse, but charging is slightly rougher than discharging.

During charge the lithium ions need to intercalate into the graphite anode, which is slower than the reverse.

It is possible abiogenesis is such a low probability event that it occurred once since the exact conditions weren't met. The earth is not very similar to early earth currently.

Consider endosymbiotic hypothesis. The evidence is that it seems to have occurred at least multiple times (mitochondria, chloroplast, nucleus) in different geological eras. I would expect if life had a high enough probability to happen multiple times, it could occur in different geological eras.

These blanket statements about “violence” are mostly devoid of meaning. What are we defining as violence in this context such that someone could be “smarter” to avoid it? Is the suggestion that someone getting assaulted should be “smarter” to solve their problem? What about protesters that are being attacked by the police? What about a country that is being invaded? I don’t understand how intelligence can fix “violence” or what “violence” even is in this context.

Moreover, asserting that we need “world wide consensus” strikes me as an incredibly naïve point. Is there anything that everyone agrees on? Are we stuck with violence until everyone agrees? Grand statements about getting along don’t seem to chip away at the problem at all. In fact, I would assert that they are fiercely counterproductive; one can say we all need to get along and until then we have no culpability.

I prefer Cantor's first proof of the uncountability of the reals to the diagonalisation argument.

Perhaps my favourite proof is this:

As a continued fraction, 1+sqrt(2) = [2;2,2,2,2,...].

Hence sqrt(2) is irrational.

A close second is this:

Let n be an integer with n>2. Consider 2^(1/n). If this is rational then 2^(1/n) = a/b. Hence 2b^n=a^n, which we can write as b^n+b^n=a^n. By Fermat's Last Theorem that has no solutions in integers, hence 2^(1/n) is irrational.

But my choice of favourite proof varies from week to week.

Some overlap gets reduced by always assuming that the "lowest" finger is choosen to a specific key and seeing how many combinations can be reached from there upwards.

Also allowing for not all fingers of a hand being used. Since one finger is set, we only look what the remaining 4 can reach:

14 choose 4 + 14 choose 3 + 14 choose 2 + 14 + 1 = 1471

this works for 74 positions for the lowest finger. For the top 14 positions we have to allow all fingers of the hand to be inside the 14, so here we have to add 14 choose 5 = 2002

so 1471 * 74 + (1471 + 2002) = 112327 should be accurate for one hand (or + 1 if we consider the "no fingers of this hand used at all"). That squared is 12.6 billion, but of course there's overlap in there too between the hands. Don't have a clever idea for that one right now that's not just enumerating scenarios...
Very unlikely. Winter batteries aren't a huge problem as long as you are gentle until the pack is warm. Hot batteries are more of an issue, as they don't really like temperatures above 90-100 F. Keeping the battery at half charge helps reduce that damage a lot.

Ultimately if you live in a hot climate the best thing to do is have a cool garage. The higher heat while out and about is not an issue, just the constant level of high heat. The only people who would get a real benefit from high temperature batteries are those without. Batteries are much more expensive than tires and the market is smaller.

Then why isn’t there ANY examples of life simpler than a bacterium, which itself is insanely complex? Why does all life share the same genetic and amino acid coding system, a relatively arbitrary choice?

More likely, in all seriousness, that life originated in Mars and came here via panspermia during the early bombardment period. Mars was warm and wet while Earth was still suffering cataclysmic impacts and only relatively mature examples of Martian life (e.g. bacteria) would have survived the trip.

If life originated multiple times on Earth there would be evidence for that. Heck if life originated on Earth there should be evidence for that, which there bizarrely isn’t.

>It's not like France will invade Spain anytime soon.

Well, Europeans powers fought twice among them in the 20th century. And in its beginning many said the exact same thing (there was even a popular book called "The Great Illusion" about how a great war in Europe is no longer conceivable, because peace and commerce). Similarly, after the collapse of the USSR a Japanese-American thinker smugly wrote about the 'End of history'. We saw how that turned out...

The main reason Europeans powers have stopped in-fighting in the latter part of the 20th century is because they were devastated by the previous wars, in the process of losing their colonial empires (and like Britain, France, etc) and so had their concerns elsewhere, e.g. France in "Indochina". Some were also under control (from USSR), and Germany was split into two and under US and USSR supervision. The power balance had shifted between the US and USSR, so there was little at stake for the European powers to fight, even if they had the might.

If more things get at stake, including after long and deep recessions, perceived or real threats to sovereignty, resources, etc, in a troubled climate-change-hit late 21st century, all bets are off.

>No, so that Europeans don't pay extra taxes for duplicate stuff.

The EU only makes sense if it's a shared political and cultural vision (which at the moment it's not).

If European countries want to avoid "extra taxes" and want to think of their economic interest, then should probably do the inverse, and split from the EU (keeping only the trade deals), so that they have their own local currency they can control, instead of a currency that's tuned to Germany's economy (or to some compromise that either hurts the weak economies or the strong ones).

Though this is only speaking about a recursively defined regular expression language which is infinite, which strictly handles regular languages, as defined in computer science lessons in university.

And then, "Why not just try and see if it breaks the provided regex parser since you have one?", and it's actually one of the answers in the link… awesome. I wonder it is has security implications though (are forged regexes exploiting flawed regex parsers a thing?)

If you need general talent like that, make a general talent job posting or put a message with a generic jobs@company email address at the top of your job board.

That signals that you're willing to consider people who don't currently meet any requirements on any of your jobs.

That also gives you the option to shut it down if general hiring has to freeze or you stop having the time to review general talent because you need to prioritize hiring for specific roles.

I really think that for a lot of positions out there, there really are very few requirements actually needed (e.g. security clearances, certificates). Everything else really falls under ideal or nice-to-have.

Requirements changing based on the candidate means they can probably be reduced or eliminated entirely. That might even increase the talent pool that you can choose from by inviting others to apply.

Hell, maybe we can start putting the same effort into writing good job ads that candidates put into their resumes, cover letters, and interviewing skills. It'd be nice to have some reciprocation in the effort department.
This sort of thing is why I consider Excel a programming environment for non-programmers, likely the best ever created. Of course most users will never use it to it's full potential (which might well be boundless..) but it nevertheless is simultaneously powerful and user friendly in a way that lets people who are ostensibly non-programmers perform novel computations that the creators of Excel never anticipated. Many consumer applications, particularly modern ones, keep their users on rails. Predefined UX paths that execute pre-defined algorithms on data provided by the user. The user is typically hopeless to solve any problem not explicitly anticipated by the creators. They can't extend the functionality of the program simply by interacting with it. Conversely a program like Excel blurs the demarcation line between user and the developer by empowering the user with a novel graphical programming language (and tricking people who think of themselves as non-programmers into learning how to use it.)

Sometimes I wonder if spreadsheets had not been invented until today, could you convince the gatekeeping UX experts employed by major tech companies to let you bring such a product to market?

Meritocracy is a spectrum really. Essentially if it looks only at current merit regardless of the circumstances it is still technically meritocratic even if it is unfair.

If only the best fighters can be knights but those raised in wealth have a vast advantage but any peasant outliers can become one it is more meritocratic than one which only allows those of noble birth but selects from canidates within. The fact the nobles compete is the only thing which gives a scintilla of meritocracy.

A system of commissions for officers based entirely on wealth would ironically be less meritocratic than the nobles only pool because it doesn't factor merit in at all.

The adhectives eglataran and meritocratic are technically two separate aspects. Although they are synergistic in that the aspects are stronger together than apart. Equal opportunity of resources would be more meritocratic than a "pure" meritocracy and more meritocracy undermines "gatekeepers" which may emerge among eglatarans where merit isn't what determines advancement.

“It is not something I think about a lot, for fairly obvious reasons, but I would like to believe that, if I won a Nobel Prize, I would have enough self-control never to mention it to anyone. Not because I am not desperate for approval and prestige! Certainly, absolutely, I would want everyone I ever met to know that I had won a Nobel Prize. I just mean that it would be so much more satisfying (for me) if they found out on their own. Like I would have normal chats with them about the weather every day, and then one day they would say “oh hey someone told me the other day that you had a Nobel Prize, I didn’t know that, that’s amazing, why didn’t you tell me!” And I’d be like “oh that old thing, yeah, it’s not really a big deal, I never think about it.” Look, I do not know if I could pull it off. Would I occasionally drop cryptic references to Stockholm to try to help them along? Sure, of course, I am only human. But I really do think that I’d mostly be able to delay gratification, because when they did figure it out it would be extra sweet.

“On the other hand, in addition to never winning a Nobel Prize, I have never been to Burning Man, and it’s possible that if I spent a week in the desert with weirdly dressed strangers almost all of whom are either tech founders or hedge fund managers, I might just end up wearing my Nobel medal around and taking “Alfred” as my playa name. I assume Burning Man is mostly a weird form of charades where everyone dresses up as a hippie and tries to get you to guess what app they invented. I don’t know. All of this feels far enough removed from my actual experience that I am kind of groping in the dark here.”
