@Jake And some require a negative PCR. OP is asking about the latter.
J...
Apr 29, 2022 22:16
Even if you're recovered from covid you can still test positive on PCR for weeks or even months afterwards. If you're intending to go somewhere with PCR requirements there is no solution - either you make sure you're PCR negative ahead of time and keep yourself quarantined until your trip OR you wait for restrictions in your intended destination country to change. The risk cannot be easily managed.

@mckenzm I've never heard anyone call Python "porn star" or anything else for that matter... it's not even ambiguous. Who is saying it wrong, and how? I mean, other than BrE/Aus reducing the 'o' to a schwa, or like the Irish who drop the [θ] for a [t]... normal regional variation. Is there a secret war on the pronunciation of Python out there? Or am I missing a joke?

@alamar Well, the whole point of NATO is to be prepared for Russian aggression... and it would seem that NATO was right to believe Russia was neither sincere nor that they had abandoned their militaristic and autocratic mindset still bent on conquest.

@DJClayworth And yet here's you debating. There was no evidence presented that what Alice did was deliberately provocative or antagonistic. If there were then I'd agree with you but that doesn't seem to be the case.

@DJClayworth Getting pissed off is entirely under the control of the person who allows themself to become emotional. If managers are losing their cool simply because they are uncomfortable with a subordinate having better ideas than their own, then perhaps it is they who are in greater need of management.

You don't manage people like Alice. You get out of their way, you help them if you can, and you pay them whatever you can afford.

The field is extremely important here. Lots of engineering still happens using US units. Structural, civil, stationary engineering, power generation, etc. Buildings are often dimensioned in feet in the US, concrete is specified in psi, steam temperatures are measured in F, turbines give efficiencies in BTU/kWh, even. All types of norms and conventions exist in engineering subfields. The question cannot be answered without more information.

@FreeMan My point was that you don't have to infer this from a radar map - there was a NOTAM posted the minute war broke out. Civil aircraft never fly over warzones. You're guessing at something that needs no guesses.
J...
Mar 3, 2022 05:34
"They're probably avoiding Ukrainian air space too, just to be on the safe side." You're kidding, right? I mean, there's no "probably" involved here - it's a warzone with active military aircraft shooting things on sight. Of course they're avoiding Ukrainian airspace.

@Tom Keep in mind that the likelihood of megaton bombs going off is extremely low. Putin and his whole chain of command would basically be in a murder/suicide pact at that point. The real threat of this war that nobody wants to talk about is normalization of tactical nuclear weapons in land war. Obviously the US isn't going to flatten every Russian city with ICBMs if Russia decides to start cracking off small tactical nukes. What nobody wants, though, is pandora's box to be opened - once tactical nukes are on the table for normal war then everything changes about war. Forever.
J...
Mar 2, 2022 22:25
@Tom And if you really want to sleep well... Russia has a 10:1 advantage in tactical nuclear weapons over the US.
J...
Mar 2, 2022 22:25
"A few km" depends on the weapon. Some nukes, yes - others no. There are much smaller weapons with much smaller blast radii. Also, at a few km distance the shockwave doesn't hit for at least a few seconds. The heat and radiation hit instantly, at the speed of light, but if you're sheltered from the initial flash you do have a few seconds, depending on how far you are, to take cover before the shockwave hits. Surviving the first hour is the most critical.

@StanOverflow I understood it perfectly fine. You deliberately insisted on ignoring context and spun a ludicrous theory based on a flimsy argument in a fantasy world. Yes, vehicles can park next to each other without signalling war. But not these vehicles. Not in anyone's most charitably imaginative fiction could those Russian units be considered to be doing anything but being 100% BOLDLY hostile. Anything else is just being deliberately disingenuous.
J...
Feb 28, 2022 18:48
@StanOverflow Well, to my ears it sounded like a desperate and laughable attempt to dismiss blatant Russian aggression. It's something I'd expect from a Russian troll, not in a serious discussion.
J...
Feb 28, 2022 17:32
@StanOverflow Well, in the context of this Russian invasion force it's not a terribly helpful, useful, or insightful observation. Context is everything, and this answer was not shy on context. There was no doubt among any military observers here that Russia's actions were aggressive - overtly, blatantly, and shamelessly aggressive. I can understand Putin grasping at straws by attempting to construct an innocent narrative based on alternative facts, but you?
J...
Feb 28, 2022 15:45
@StanOverflow If you're absolutely determined to completely ignore ALL of the context, sure. But this is deliberately sticking your head in the sand. You're free to stare at the biggest assembled invasion force Europe has seen in 75 years and call it an innocent tailgate party if you like, but it was stupid to claim that Russia's posture was not aggressive ten days ago and it's monumentally insane today.
J...
Feb 24, 2022 18:17
@StanOverflow - Well, the proof is now, as they say, in the pudding.
J...
Feb 16, 2022 17:41
@StanOverflow I feel like you're deliberately avoiding the "why" question. Are you suggesting that Russia just took the army for a walk? Why would they reposition to the Ukranian border, hang out there, and then leave again if not to communicate an intent to attack? If you're honestly arguing that this could have been a purely innocent military movement with no intent of making a show of aggression then I don't think we have anything further to discuss.
J...
Feb 16, 2022 17:41
@StanOverflow You started this by objecting to the conclusion that their formation implied a preparation for attack. My point is that all other possibilities do not make logical sense - either they are positioning to attack or they are positioning to give the appearance of an attack. My only point was that concluding anything else, like they might just be in the area to count the pebbles in Rostov or something, is really just being fatuous.
J...
Feb 16, 2022 17:41
@StanOverflow Yes, and the other remaining interpretation is "make it look like you're about to attack", which was precisely the point I was getting to. Please don't put words in my mouth. And not the future, but yesterday, in fact... at least that's the narrative now. Of course Putin is playing games.
J...
Feb 16, 2022 17:41
@StanOverflow And since there's nothing to retreat from and since they just got there after recently repositioning....
J...
Feb 16, 2022 17:41
@StanOverflow It sure suggests that they're getting ready to move. Why do armies move, you might ask?

@cas The 90s was a warp tunnel. Mid and late were very different. Mid 90s monochrome would not surprise me. By 1999, though, they were nowhere - you'd have been among a very rare few that were still holding onto them. The last of the classic monochromes were the Apple 20" and those were 1989. That's two or three computers before 1999.

@grovkin Neil's point was about a 7-month pregnant woman working in a coal mine. Pregnant women have special constrains that limit what they can safely do. Certain industrial and laboratory chemicals, for example, have exposure limits for normal workers that are dangerous for a developing fetus and so pregnant women are disallowed from engaging in such work where they may be exposed to an environment harmful to the unborn child. I didn't say anything about working with children.
J...
Feb 7, 2022 18:50
@grovkin Hooters is not a place for children. It's a restaurant where men pay to see women serve them in small, tight clothes. You might arguably consider the men that frequent such establishments as "children", but I think that's beside the point...

@Clumsycat If you can show math that makes sense and proves your point I'll believe it. I'm convinced it doesn't exist. Otherwise, you're arguing a dead case. I will never tell you that this proposal makes sense, so don't bother trying to make a case based on intuition. The system will fall apart no matter how you slice it. It's neither stable nor physically possible. If you change the angle of approach and exit the orbit furthermore ceases to be a squircle. It's now a spirograph...and unstable.
J...
Feb 4, 2022 15:16
Consider that if the four bodies are static the system is impossible because no structure can hold them there. If we allow them to rotate they must rotate at whatever co-orbiting velocity the universe demands for their size and distance. At that rotational speed, a planet trying to orbit the four OUTSIDE their co-orbit cannot go faster than the four themselves. There is no way to make this work. One way or another it requires magic somewhere.
J...
Feb 4, 2022 15:10
@Clumsycat The issue is that it's impossible. It will fly away If you want constructive, go calculate the system and see for yourself.
J...
Feb 4, 2022 14:32
@Clumsycat If you slow the rotation to a speed that does allow your "bent squircle" idea, you're back to fighting gravity with materials from science-fiction. It is utterly impossible. I defy you to come up with numbers and materials that satisfy the laws of physics and this system at the same time.
J...
Feb 4, 2022 14:32
@Clumsycat Because you haven't fully thought it through. Consider the rate of rotation required to relieve the system of stress (ie :four co-orbiting massive bodies). Now you don't need a ridiculous strut system between them. Consider now what the orbiting velocity of the small planet would need to be for the squircle orbit and notice how everything falls apart.
J...
Feb 4, 2022 13:19
@Tristan Planets aren't light. Even the smallest dwarf is still 10^22kg. The mass ratio is irrelevant, and the larger you make massive bodies the more impossible your support structure becomes. There is no known configuration of matter which can withstand these forces. You could only ever make it work with objects MUCH smaller than planets. @Clumsycat The system cannot be allowed to rotate or it doesn't work. There is also no way to stop the system from rotating, so it is impossible.
J...
Feb 3, 2022 15:50
No bending forces? What do you think makes the planet turn around the corner? Have you calculated what torques look like on lever arms measured in astronomical units? Go do the numbers - don't trust me. It is impossible.
J...
Feb 3, 2022 15:40
@Tristan Physics does not allow materials with the required properties. What you think of as "solid" objects aren't on this scale. Our intuitions are wrong in such an environment and you cannot use them to guide your thinking. Do the numbers. You could maybe achieve this for some time with small objects in an isolated void, but not stars or planets large enough to be called planets (ie: gravitationally self-rounded).
J...
Feb 3, 2022 15:40
@Tristan "to provide some of the centripetal force needed for a rotating assemblage" - it can't be allowed to rotate or the squircle orbit becomes impossible.
J...
Feb 3, 2022 15:40
@Tristan Space is vast. I don't think you've considered the numbers. Fantasy will need to be invoked at some point to make this plan work. "Rigid" is not possible over such distances.
J...
Feb 3, 2022 15:40
Not that it matters because the four fixed corner assumption is physically impossible anyway, so there is no "in practice" to worry about. This can't happen.

#26 In Canada is probably Ryerson if you're going by QS, and if you're going to turn your nose up at Ryerson for prestige reasons you'll have a hard time find a better school to go to. That's an excellent university, especially in the technology sector. At the postgraduate level, it's not the school that matters so much as the student. An excellent school won't magically turn you into a superstar student if you're not one already. If it provides the resources you need to study what you want then it's really going to be up to you to succeed, wherever you end up.
