TRUE can be the identity element both for the conjunction of 2 Boolean values, and of an operator that extends 2-value Boolean operations to lists of N-elements.

Being an identity is a property. A given mathematical object can be an identity for more than one relation.

It can also be the identity element for general logical propositions or relations.

The reason being, the former is just a special case of the Boolean relations of AND and ALL.

So TRUE can consistently be the identity for many classes of logical operations of varying generality or complexity.

The raw identity relation and concept of identity element form the “tops” of ladders, whose specializations can hold over large classes of relations.
Personal anecdote: The wife of someone I know got a full body scan in Germany (because they were outlawed in the Netherlands, don't know if they still are). Clean bill of health. About 4 months later she was in the hospital with cancer.
I'd really like to know whether they considered wildfire risk when they hatched this plan back in ~2017.

Agree! to be pedantic, you should probably add a "within the next X years" qualifier
They offer MRI combined with PET. They give you a high dose of iron for to see things better in the pancreas. PET scan uses like radioactive sugar to find hungry cancer, even tiny ones. MRI is used to find large scale structural problems.
It's an MRI, there's no radiation. And I understood these scans look for changes more than specific structures, so have fewer false positives than just a one-of

Heh, I missed the mom reference, but the forks in socket, chemicals under the sink (which they did NOT drink) and tide pod (which they did NOT try) comment was funny and endearing.

It certainly is unusual, and probably inappropriate in a resume, but I've always felt the strict conventional rules for resumes stifle a lot of creativity and strip people of their personality and uniqueness. It probably would get them rejected from most companies, but I think it would also help them get noticed by other companies. They only need to get through to one!
They couldn't make a more blatant hit piece.

The only damage they actually cite despite claiming to have access to a 1100 page report is someone's trail camera seeing birds getting scared off and their eggs being eaten by another animal...

The rest is all whining about not being allowed on site after the self-admitted dangerous explosion for 48 hours and a bunch of "but the experts (specifically the ones we prefer) say they definitely need a flame diverter". Then they wonder why SpaceX's protocol is to ignore media rags.

The design decisions that led up to the decision to not have a flame trench weren't exactly secret either. They wanted to avoid it because they would have to build up the area to be able to have a trench, which would take many years and would end up being a high cost for every launch site they might want to build, and so they tried to come up with a design that could get by without one. By the time came for the orbital test, they knew the concrete would not be sufficient and the water deluge system was already in development, but they expected that the concrete would be ablated. Instead it unexpectedly shattered due to interactions with the sand underneath.

However, saying that isn't convenient for the narrative. Many of the "experts" they're citing likely also made claims about how reusable rocketry isn't economical or that pin point landings on a barge in the middle of the ocean would not be reliable every time there was a failed attempt during the early days of that.
This one had me in tears for a good 10 mins. I can't tell if it deliberately "rough" or genuinely the artists skill level.
There was a very real possibility that the rocket would have exploded on the launch pad. This possibility was acknowledged and accepted in the environmental assessment. An explosion on the launch pad would have done far more damage than occurred due to insufficient pad protection.
if you apt install libluajit-5.1-dev you can compile and link your c programs with it without having to compile it yourself

similarly if you are writing programs in lua rather than in c you can run them in luajit if you just apt install luajit

if you want to release your programs as free software so other people can compile and link them, it's important for them to be able to get the version of luajit you were using so they can debug why your program doesn't work in the current version of luajit

Hetzner seems to allow 7 snapshots total [1]. That means you can keep 1 week of daily backups, or less than two months of weekly backups. Either way, it's useful for the "server burned down" situation, but not really for the "can't find this file", "I want my previous config", or "this file got corrupted somehow" situations.

Pyanodons is a unique experience. Everything has dozens of steps. In the base game, circuit boards are made from copper wire and iron plates, whereas in Pyanodons, you need formica for the PCB substrate, which requires tree nurseries to make wood and a full coal cracking facility to produce creosote, a glassworks, half a dozen different metals, not to mention pick and place machines and all other sorts of intermediates. And that's just baby steps.

But it's flawed in other ways. In particular, a lot of the Py building sprites hide what's behind them. In the base game, all the sprites aren't taller than their footprint, but they are in Py, which makes them unwieldy and easy to lose things. And what's fun is building these huge production lines, but there's no easy way to tear up your old base and reconfigure things until you hit bots, which is waaaay down the line.

In short, Py is wonderful and I've never played any sort of game like it before, but it has unnecessary rough edges from a game design perspective, aside from its masochism.

> let's abandon Mars

The idea that Musk’s plan with SpaceX is to help humanity colonize Mars is nothing but PR hogwash. The sole purpose of that messaging is to get ordinary members of the public to defend them when they break the rules for their own financial gain. It appears, at least in your case, to have worked.
Everything fast food/drive thru needs a straw.

The rest of the usage is mostly because everywhere got rid of actual teaspoons so you could stir things into your drink.

It's quite infuriating. In Austin, for example, most restaurants used to serve 32 oz(yeah that's a big-ass glass) of unsweetened(!) iced tea with a lime wedge, and it came with a long-ass teaspoon to go with it. Now it's far smaller glasses of drinks with enormous quantities of sugar already pre-blended--sometimes you can't even find iced tea anymore.
48V DC is already in the dangerous voltages to work with in the home. The human body can already bridge such a voltage, but as opposed to AC, muscles will freeze in position, effectively getting stuck in shock position.

I remember visiting a datacenter once that ran telco equipment on 48V DC. They were much more paranoid about us getting close to such equipment compared to the AC equipment because they de need to "unstick" us. Cool gear nonetheless

I'm critiquing the presentation.

"helloSystem is a desktop system for creators with a focus on simplicity, elegance, and usability. Its design follows the “Less, but better” philosophy. It is intended as a system for “mere mortals”, welcoming to switchers from the Mac."

Or Mindustry, which is open source: https://mindustrygame.github.io/

Mindustry has two "planets" and they play entirely differently. The newer one, Erekir, is a mix of Factorio, tower defense and RTS elements.

I actually liked it a bit more than Factorio, because it is less complex.

I didn’t really like the first planet though (Serpulo) and stopped after playing through Erekir twice.
To be even more pedantic! Unit elements are not limited to binary operators. In fact, in a monoid (or group) there is naturally an n-ary operation for each n. Or if you want a single operation from lists of elements to a single element. It is just that we usually present it using a unit and a binary operation + associativity. But one can split that cake in other ways. Thus, in some sense any and all are even more natural or "objective" (as Lawvere would put it) than and and or.
It's obviously not possible with existing technology but future developments in biotechnology might lead to breakthroughs in terraforming planets like Mars for human habitation. In any event, fewer rockets is not going to prevent the 6th mass extinction. The biosphere is degrading and fossil fuel consumption is still going up because the economists have decided that higher GDP is better than a habitable planet. Musk is a favorite scapegoat but he is not the problem. Modern civilization is toxic and will continue to generate toxic byproducts as long as the human population is increasing.
J&J still exists and will continue to exist though? They settled for some 9 billion, which is a lot but not enough to sink a company with a ~400 billion market cap.

Wow i had no idea that had almost happened!

Anyone care to elaborate further on that?

I wonder what could have been, if later solaris was open sourced and google could push their improvements… maybe we’d all be running containers based on solaris zones, and would have solaris on our smartphones? Who knows!

It's not just the anxiety and psychological distress either. If we scanned everyone all the time, you would find literally millions of conditions that would never cause symptoms or major health issues, but would nevertheless be treated unnecessarily, incurring massive additional costs and needless interventions with their own risks. It would be a nightmare.

Doing a CT or PET scan just for fun is not a great idea, because of the radiation dose received.

However, MRI is completely benign. It doesn't expose patients to any dangerous radiation and is minimally intrusive (you just need an IV for contrast).

Thank Goodness You're Here [New Game from Panic]
That's exactly the problem though: rather than to build upon the ideas in the article all you did was find fault with a single word, and that drove your comment. Instead, if you were to take this serious you could approach it constructively rather than destructively. It's maybe a bit more work but I think the cumulative effect of that would result in a much better discussion around the subject matter.

6 degrees difference sounds like it is huge, right? But: that's 6 degrees with a margin of error, and with a difference per species (it is an average!) that further enlarges that margin for error. Then there are possible feedback mechanisms to contend with, as well as various local effects. Rather than to just accentuate the fact that 'approaching' is doing the heavy lifting it would be trivial to point out that this is how scientists communicate around things they are not 100% sure of (and that includes most things), but meanwhile us silly laypeople should not assume that because the statement is made carefully that it still is a warning and so can't be dismissed out of hand. That is more typing but it takes you out of 'dismissal', which is how I read your original comment, especially with the 'far more' in there which is - ironically - doing a lot of heavy lifting in your original comment.
Damn, one of the worst parts about cancers is that there isn’t information on how fast they grow unimpeded, so that messes up knowing what interval would be best

That’s nothing to what other capabilities are used in protests by law enforcement, for example, if you fly any consumer RC drone, most likely they have the AeroScope running to capture the drones AND the pilots’ locations, it was actually used in Canada in one of the big protests happened before. However, if you build your own drone and you don’t fly it over RC link, it is a lot harder to track.
I think that long term, preventative scans do make sense. With that preface, I don't think we should just argue there are no problems, and it's all easily solvable.

"Too many false positives leading to wasted time and costs? Raise the costs for the supplemental scans and improve detection precision and recall."

You can't improve precision/signal on an inherently weak and noisy signal. There are many things showing up on MRIs that currently require a biopsy. You need alternative DX routes to disambiguate, MRI alone can't do that. As for raising the costs - who pays? Medical costs are already completely bonkers.

"That’s a sign to improve medical research in that area. "

We know we need to improve search. We don't need to cause negative outcomes to reinforce that signal.

"Too much demand for MRI machines pulling away time from patients that need to use them? Build more MRI machines. "

Again, who pays?

"we should just plow ahead and address new problems as they arise."

There is the problem of opportunity cost. Is that the best possible way to spend sparse resources? The medical community currently mostly thinks that it isn't.

Targeting wealthy people first does solve the "who pays" problem. It might make the "too few researchers" issue worse. It will cause a lot of unnecessary biopsies (because often that's the only alternative dx route) - but you could certainly lean into informed consent there. You do run the risk of poisoning MRIs as a diagnostic tool, because media will report any inconvenience to sufficiently wealthy people as a major problem.

All of this might be solvable, but "let's just press ahead and see" is a very bad approach here.

Doctors will tell you don’t do this: waste of time, more harm than good, etc.

This is all fine as general advice when you see patients as mere statistics and you want to apply broad generally applicable advice for everyone.

However, it is more meaningful for the wealthier individual or a VIP to have their body fully documented. Even if no action is taken for some possible tumors, having some knowledge is better than being totally blind. And maybe it’s a waste of money, but if you have the money to waste it’s not a big deal.

This doesn't make any sense to me. It's either a problem or it isn't unless doctors are willing to admit they perform lots of unnecessary procedures already.
People will disagree but I think a lot of it is people angry that some can afford it and some cannot. In Canada we have only public healthcare, so everyone gets the same poor government service (unless you are rich enough to go to the US or know the loopholes). And people fight tooth and nail to keep it that way, in the interest in fairness. We recently has a court rule that even though people will die because of the absence of private options, that's an acceptable trade off to enforce "one-tier" universal healthcare. I'm sure doctors wanting a cut is another root cause, but a lot of it is just jealousy.
