Einstein gets the hero worship mostly because of the Annus mirabilis papers on the photoelectric effect, Brownian motion, and Special Relativity. General Relativity was more a curiosity of sorts until the 1970s, and even today people connecting astrophysical observations with Einstein gravitation tend to work with a (often linearized) approximation for practical reasons and with a range of theoretical justifications and mechanisms to connect back to the Einstein Field Equations as the underlying more-fundamental theory.

Practically every grad student encountering Kaluza-Klein (and other supergravities) or the PPN formalism will spend some time with Nordström's gravitation (and of course it is discussed in §27.6 and §38.2 of Misner Thorne & Wheeler, the gold standard textbook). In the latter case it is straightforward to see in modern terms where Nordström's 1913 theory would clash with solar-system observations (it was ruled out by the Eddington eclipse observation) and spectacularly falls apart for compact massive objects like the Hulse-Taylor binary. The theory inverts the spatial curvature generated by matter (PPN \gamma parameters for Newton, GR, and Nordstöm 1913 are 0, 1, and -1 respectively) and is only half-right for gravitational nonlinearity (\beta parameters 0, 1, and 1/2). Einstein-Fokker 1914 fails under PPN analysis in the same way, except that they properly fix the \zeta_{4} dynamical conservation parameter as 0, unlike Nordström 1913.

In my view, early 20th century alternatives to GR are interesting for how they failed. I accept the part of your argument that it is more interesting to some than to others about how much cross-fertilization there was among the developers of these theories. However, only GR has survived contact with all experimental tests, and it has proven extremely difficult for alternatives to match over multiple solid angle and wavelength scales what astronomers observe. The ways in which various extra-field approaches have failed are frankly more useful for theoretical physicists than the ways in which they were developed in the first place. And for astrophysicists, the only thing that matters is what has not -- so far -- failed.

So however he got there, at least with respect to gravitation Einstein deserves recognition for having produced pretty much the only viable physical theory. There's really only Jordan/Brans-Dicke in the limit of a vanishing \frac{1}{\omega} parameter, but at zero the theory reduces to GR itself; Einstein-Cartan-Sciama-Kibble if one does headstands to suppress spacetime torsion; early-decay bimetric theories, where the second metric field decouples or vanishes before nucleosynthesis; supergravity, if one figures out how to hide the gravitino; and string theory (M-theory), if one figures out the landscape problem and/or works out a general emergence of a PPN match. Notably every one of these evolved from General Relativity mostly because of its unique successes -- however, I think it is more interesting and better to say that these remain viable because they can in certain circumstances fully reproduce General Relativity.
Hmm, I could see some more sci-fi, dystopian applications:

- Gaslight someone by making them hear voices

- Threaten someone then arrest them when they attack since to bystanders it appears to be unprovoked

- Similar to the previous one, provoke/trick protestors into "unprovoked" violence

- Trick someone into walking into oncoming traffic

- Harass someone without anyone else noticing

Nato writes on their web site that "Participation in the MAP does not prejudge any decision by the Alliance on future membership"

https://www.nato.int/cps/en/natolive/topics_37356.htm

--in other words their being invited into a MAP does not mean they would have been invited to become a member.

When the USSR collapsed, George Bush the elder was President, and he was one of the US's best Presidents on foreign policy, and no way he would've gone along with offering NATO membership to Ukraine. If the Obama adminstration was willing to do it, I find that depressing because NATO does not have the conventional military strength to defend Ukraine from a Russian invasion, and of course would be unwilling to launch a nuclear attack on Russia over the fate of Ukraine. It would be a mistake for NATO to make any public commitment it is not willing and able to keep. Credibility is essential for avoiding war.

World Economy Edges Closer to a Recession as Trade Fears Spread
I'm stuck in London right now trying to get to Athens on British Airways because of this IT failure. I went to a gate of an earlier flight where they had opened up a couple of seats, and the gate agents were trying to get me on, but the computer system didn't let them do it and they had to let the flight leave.

It's interesting to see the breakdown of automation. Lines are long yes, but they also don't move because everyone's situation takes half an hour to explain and lots of manual labor to resolve. There's sort of this competitive mentality (leading to frustration) because there are some alternate options (like flights on competing airlines) but every time you refresh, the options dwindle and you can't do anything about it without an agent. They also have run out of hotel vouchers and hotels at the airport are full. They've started processing people by just writing down our concerns and giving us a pager to reduce the length of the line.

I think a lot of this could be resolved with a better auto-booking and notification system. Like n interface that lets you enter in your constraints, and it optimizes for you better than a person can do by hand.
The word "continuous" here is used (incorrectly) to mean "contiguous".

"Continuous" means ongoing in time (as in "continuing"). "Contiguous" means "touching on a boundary". So a "contiguous data structure" is one that "occupies a single chunk of memory and its contents are stored in adjacent memory blocks."

Continuity would only really mean anything for time-series data.

3He-3He fusion is probably impossible. The 3He fusion reactors being talked about would use D-3He, and would still produce neutrons.

The two big issues with neutrons are damage to the reactor structure, and induced radioactivity preventing hands-on maintenance. D-3He could help with the first, but not the second. A D-3He reactor would still have to be maintained remotely, with robots. At best, it would reduce the radiation load on the robots.

The need to maintain fusion reactors with robots reminds me of what they did at the hot cells at Hanford to ensure they could be maintained after being used for reprocessing. They required that the operators install all the equipment there using the remote handling equipment (mechanical waldoes, not robots). I'll believe the fusion people can maintain their reactors when they do the same thing.

I'm not sure pointing out undefined behaviour is nitpicking. It could in some cases be crucial. At the very least, it ties your code to only some Common Lisp implementations.

I know you can assign to keywords in LispWorks (using a restart), but that should be done in your rutils library, wrapping the definition of :=, :*, :/. And then you should do the same for all other implementations, which may differ in what condition is signalled, and whether there really is a restart for this, and of course whether it actually is allowed in that implementation.
Speaking as someone who (for a time) worked in the IT department of British Airways, the culprit is really just ancient systems that aren't well maintained, along with institutional and industrial pressure not to improve them or upgrade them.

For example, I worked as part of the team that managed the software that allowed pilots to submit flight plans. Any upgrades had to go through multiple weeks of reviews and testing (I don't mean code review - I mean reviews through managers and processes), and was run on some rather ancient hardware. Moreover, thanks to pressure from the pilots union, the system had to be able to accept flight plans by fax, so had a lot of legacy cruft to support that too.

The problem isn't agility, corner cutting or moving too fast - it's moving too slow.
Nowadays you can install Steam on a separate drive. I have a 500GB PCIe SSD but install my more intensive games on a regular SSD and then the rest on a 1TB spin disk. So in a way you wont always install it in Program Files if you pick a new location to install.
It would be optimal for all researchers to coordinate to move away from Elsevier, but as long as everyone else (or the majority) is publishing in Elsevier the local optimum for each researcher is to continue publishing in Elsevier.

I know a few researchers who have publicly committed to not publish in Elsevier journals, but there's a career cost to doing this, particularly for early career researchers. Outside of a small number of colleagues who will actually read your work, most people (including funding organizations and tenure review boards) will judge your research by how much you publish and where you publish, and Elsevier owns many of the most prestigious journals.

It varies by field, depending on how many journals Elsevier has managed to capture. I consider myself lucky that Elsevier doesn't own any of the major journals in my specialty, so I've so far been able to avoid them without feeling like I was making career sacrifices to do so.

As for the dramatically faster, the ripgrep author doesn't claim this. What he claims (and supports with benchmarks) is the obverse, that there are no other tools dramatically faster than ripgrep.

How would that work for you? You would end up in prison.
Some things you need to identify and understand: lane markings, police officers, temporary road signs, construction workers guiding traffic, traffic lights, someone waiting at the "yield to pedestrians" crosswalk, emergency response vehicles, ice patches. Just "not running into things" isn't enough to drive on roads. Really you should be trying to understand every vehicle since a naive approach of just extrapolating their velocity is insufficiently cautious since it doesn't account for future acceleration which can cause a crash.

>Even when trying to identify objects, I don't get the push for trying to understand what they are.

Without that you don't know lots of things.

1) Whether they might move or are completely stationary (e.g. a pole vs a motorcycle).

2) How they move.

3) Which you're better off hitting if you need to swerve to avoid another car (is it better to hit the fruit stand or the 10 year old boy?)

4) Whether they tell you something (e.g. traffic signs, traffic lights, a traffic cop directing you elsewhere, for starters).

5) Whether they represent some danger and you need to keep a distance (e.g. a bus with open doors, from where someone might come out at any minute).

apartheid in particular refers to West Bank (eg East Jerusalem) Palestinians that blue cards (so they can travel freely in Israel but can't own property in Israel, can't move residences in East Jerusalem, suffer road closures and checkpoints, and don't have access to any social services.

Re Independence of Gaza and etc. Yes idf pulled out but there's a blockade. So let me ask you what you would do if lived in an open prison? Do you think maybe you would lash out? And about those rockets which are not much larger than bottle rockets: how many Gaza Palestinians are killed for every Israeli during and incursion? During a bombing? Answer 200x times more https://en.wikipedia.org/wiki/Gaza%E2%80%93Israel_conflict . I'm not saying that the Palestinians are justified but that Israel's response is untenable - if a child strikes an adult it is unacceptable that that child is beaten within an inch of their life.

It's interesting how the internet enables wishful thinking like this. You'd have thought the dearth of peer reviewed papers about Polywell would have been a clue, but true believers admit no impediment to their belief.

Safety systems certainly need to work in all conditions, but “work” in this case may mean refusing to activate in conditions outside its design range. It’s fine for a self-driving system to refuse to drive in a blizzard; it’s not ok for it to try and then fail to drive in the blizzard.
Sorry, getting back to the initial point: can you point to a statement in the standard that forbids assigning to symbol-function of keywords or dims it unspecified behavior?

Besides these constraints, the keyword symbols are normal symbols so they should abide by the same rules.

Why don't you clear up these numbers? I think you are a denier and simply refuse to see the other side of the coin. Even refuse to accept that Europe has faced a massive immigration issue. Turkey got almost 4 million refugees. Were not the EU agreement these people would be heading towards Europe.

The issue it's not really complicated. You just have to admit that massive immigration has some social and economic costs. Maybe not for the wealthy but surely for the leas fortunate "natives". Right wing wins because of deniers like you who can't provide a compromise solution. "Let them all in and we see afterwards how we handle it" doesn't put people at ease. Not to mention the security risk.
