I would use Guix rather than NixOS, but I wonder if I would feel as in control as I do as a Gentoo user. I suppose I should set aside some time to try it in a VM.
Maybe. Although I think it really takes a multiplayer open world (possibly an RPG?) to even get close. I wonder if people
who use to play WOW back in the hayday of its popularity feel

It's not wrong, and makes the maths easier ... as long as we're happy to shift our reference point when appropriate, it seems valid to me. The CoM of the local galactic cluster isn't particular useful as a reference and is no more valid a default.

I don't like this argument for three reasons:

1. The single thread performance gap is very small (5-10% depending on application) or even non-existent in some cases.

2. Your computer runs more than one process at any given moment. The more cores, the more processes you can run without an impact on performance

3. That single core performance comes at the cost of efficiency and general power usage. Intel has had to clock their 14nm process very high to achieve that small lead in single thread performance.
I'd say "spacings and margins" fall into the "pixel perfection" category for pretty obvious reasons.

Divergence in "behaviours" and "generally agreed-upon layouts" is possible even with native toolkits, so I fail to see how Qt or Tk are a relevant factor here (both of them give the programmer the necessary tools to match the native behavioral and layout conventions, just like the native toolkits do).

Tk definitely has a disadvantage in the "accessibility" category, but Qt literally uses and abstracts the native accessibility interfaces¹, so in Qt's case this should be a non-issue (beyond the typical considerations for software accessibility that apply even for native toolkits, like, you know, actually leveraging and testing those features).

> I have not seen a Qt app on macOS that did not stand out like a sore thumb on the very first glance.

Okay, but by virtue of knowing what Qt even is, I'd wager that you ain't an ordinary user. The vast majority of end users will neither notice nor care (especially given that there's an abundance of commonly-used software that deviates from the typical macOS UX even without Qt, e.g. Office and Chrome, or pretty much every single app using Electron or CEF or some other browser-as-UI approach). The only thing that truly matters is whether or not the software works and is usable, and Qt doesn't really pose any obstacle there (and Tk only does if accessibility is a concern - which I'd argue it should be, but it's at least no worse than the status quo).

First, rude.

Second, yes, three months of heavily restricted movement, limited access to resources (from flour to dental care), to knowing people who are sick, dying, or at high risk has absolutely changed my perspective.

Knowing that we've got several more months of this ahead, this is a significant portion of our lives. One way to think about it is that most of us will have spent whole integer percentage of our lives in this situation. Of course that's going to impact the way we observe and interact with the world.

It really is not the bad, most of the time when there is actual abuse there is a social outrage and they back off.

In my good old maths undergraduate days, in many courses the notes were what was written on the blackboard in lectures. No handouts or slides. There might have been a relevant textbook, but its contents would not be exactly the same as the course.

So my default mode was to copy absolutely everything down (using my own personal set of abbreviations) whilst not necessarily understanding everything. Occasionally I would understand everything in the lecture; occasionally I would understand nothing in the lecture; usually it would be somewhere between the two.

Later I would copy out my notes neatly, but not allowing myself to write anything into my neat copy until I understood it. If it took me a long time to finally see how a step in a proof was justified, I would write the justification into my notes. If I had to revise something to understand the new material, I would write the relevant points I had forgotten into my notes. Hence reading my notes to revise for the exam could be as fast as possible.

To the extent that I perfectly carried out the above system, I gained near to perfect marks. To the extent that I didn't carry out the system, my marks suffered.
It does work, though. Here's an example: https://techscience.org/a/2019121801/ There's also https://arxiv.org/pdf/1908.09203.pdf#page=48

Why aren't bad actors using it in the wild? I think it's a combination of them being technically unsophisticated and conservative, propaganda not actually working nearly as well as people like to think it does, and lack of detection of competent actors (things like StyleGAN being used for fake FB profiles are detected through carelessness like leaving the faces exactly aligned).
The fact that the Super 7 don't want to rely upon one vendor actually gives AMD a better shot - all other serious contenders use different instruction sets, so AMD's x86 procs are compatible with existing software ecosystems, thus reducing qualification and validation results. A viable x86 alternative to Intel has been sorely needed, and AMD fills that role quite nicely.
Perhaps you can translate for me too, because I read the reply and agreed that the risk appetite for new small business owners might not be as robust given the current set of rules, which is what the commenter was saying. At least that's my interpretation. You seem to see something else in this comment.

As a result I have some clarification questions...
How do they want to "keep kicking the can down the road" exactly? Your comment about the government not being able to bail out everyone only serves to reinforce the point about the risk of starting a small business.

What do you mean by "He's right"? He's right that people will line up to start new businesses and put their diminished life savings on the line after what's transpired?

Then you flippantly say "Add UBI and nationalized healthcare", as if it's just something you add to a shopping cart and "it's not complicated". So it sounds like you assume these features as part of the assumption that people will flock to starting businesses. That's not part of the discussion at all, but it's an interesting point to discuss whether that would spur the activity. It very well might as it's the "social safety net" one would need to have more confidence.

About the only thing you said that resonated with me is "the elites just don't want it". Given the growing wealth disparity and the relative flat to down real income of the average American in the last 40 years I'd say that's a fair statement.

Your final statement comes out of nowhere as you lump the commenter into this group of elites when all they were saying is "hey man, I'm not so sure people will be lining up to risk their life savings to start a small business".

Care to try again with a gentler, more constructive tone and explain how the commenter, and by extension myself, are naive with the summarized viewpoint I stated at the outset?
I didn't complain, and I didn't even criticize it in "several" comments; the only comment with anything resembling criticism is the second one I wrote, and it's just a single comment!

I said I didn't like something as a way of making it clear that I'm not trying to brigade for Nix and don't really have any incentive to defend it, and I gave an argument on why I believe the initial comment was being unfairly negative to Nix.

I was then asked why I disliked Nix. I made no complaints, I just listed my opinions. When I was asked to go into actual complaints implying fact rather than personal opinions, I said I'd prefer not to.

My advice is actually that mistake journal: it was the single best thing I ever did for a math class. Figure out what mistakes are actually happening and develop a system or habit to avoid that actual mistake.

I've never heard of this before. That's a very cool idea.
I agree with that. I have no idea why it’s in a separate package. But I can say that about many packages :).

It’s possible to just treat everything as a promise by wrapping results in Promise.resolve() but that can have performance implications that some franeworks might want to avoid by only going down the promise route when they have to.

For promise implementations, If the callback to then() returns a promise, the promise implementation detects that and resolves that promise behind the scenes: http://www.mattgreer.org/articles/promises-in-wicked-detail/...

No, Turkey's official mortality numbers are worse than most places. It's only in comparison to Western numbers that they look good. I checked Mexico (as a good country the US could more easily learn from) and they have over 3x fewer deaths per 100,000.

I don't say that to knock on Turkey, just to explain the perspective. People aren't ignoring Turkey because they don't trust Turkey specifically; it's because they don't trust any of these numbers. The idea that there's some core competency of pandemic response possessed by almost every country in the world but absent in most of the West seems... implausible.
Yeah I am often highly suspicious of these things saying "company X uses this!" - I've seen a few of those listing the Big Co where I had been working at the time was listed where it definitely was not in-use (and in one case the software was actually banned from expensing/licensing despite being listed on the vendor's site)

Yes, we bought at discount and IIRC I assumed 80% did, it was a very popular course (I'd be surprised, given the figures were correct and the course wasn't free at any point, if I'd been more than one order of magnitude out -- which makes it still massively more financially rewarding than direct teaching: which was my point).
Honestly this doesn’t sound that different from my own competitive high school experiences almost 30 years ago. The fact that you and your peers bin Duke and Cornell into the second tier bargain bin suggests that your subset of peers may not be a representative sample of the student universe.

Deep seated stereotypes play a role, but there are many forces at work. Most people are going to fail either way. That’s simply an outgrowth of a pyramid with fewer openings at the top.

If 10x more people of type X than type Y play the game and people of type X make it to he top 10x more frequently then that’s in line with this model. Currently there are for example 4 black CEO’s of Fortune 500 companies, which is really low.

But, if the proxy is say MBA graduates in 1990, that’s also low. Family connections further muddle the water etc. It’s clearly not a level playing field by any means.

Here is a more enlightening as well as fuller quote from the president:

"And I then I see the disinfectant, where it knocks it out in one minute, and is there a way you can do something like that by injection inside, or almost a cleaning. Because you see it gets in the lungs, and it does a tremendous number on the lungs. So it'd be interesting to check that. So you're going to have to use medical doctors, but it sounds interesting to me, so we'll see."

The point being he is talking about doctors investigating and employing his "technique".

Don't get me wrong, it is disappointing that someone who doesn't appear to be able to formulate long, coherent thoughts is our president, but I am sick to death of the way some of the things he says are twisted simply because people hate on him. It is a deep level of bias.

It's alright, I made peace with people being wrong on the Internet.

I would suggest you do some research, like researching if it's a military dictatorship or not. Check out what happened to the military in 2016 when they attempted a coup. The results may surprise you.

Anyway, the Turkish health system is quite similar to NHS and the doctors are severely overworked so I wouldn't claim that Turkey has a better health system but I would claim that it is handling the COVID-19 response better than the most.

Turkey is not a closed society, there are many ways to verify these claims.

Actually, this deeply flawed understanding of the situation in Turkey is part of the problem anyway. If you can overcome this, you can learn a thing or two from the way Turkey is handling the situation. Take it or leave it.
Taking 'hard' water for granted since I was born, it's quite surprising and interesting that water cannot rinse off the soap.

This year I went abroad for a business trip. In the hotel, after washing my hands or taking showers, I found I couldn't rinse off the soap. I was so confused because it was so hard to do it, plus I brought my own soap. I inspected, smelled, and tasted the water carefully and didn't find any difference. In the end, I learned there is such a thing called 'hard' water.

My company GitClear has invested some years into this very wish. We came up with "commit groups", described here https://www.gitclear.com/review_code_faster

During development phase, our service has been priced at $30 user/month which is too expensive for a diff viewing tool, but we're going to start offering a free version in next couple weeks that will offer access to commit groups.

Here are some other experiments we've been working on to try to reduce cognitive load spent reviewing commits: https://www.gitclear.com/blog/diff_viewer_updates

I believe a lot of what makes reviewing code so time-intensive is that traditional diff viewers aren't recognizing moved or find/replace code, so devs still have to waste a lot of cognitive attention parsing what are effectively no-ops.
> Whether you've proven the right thing still requires judgement

That's my point.

Formal methods don't make bugs or debugging disappear. They move it to different domain - the development of the proof.

> what you end up with is a provably correct implementation of what you thought you wanted.

You end up with a provably correct implementation of what you thought you stated on what you thought you wanted.

Serious proofs are highly non-trivial. I've seen experts debate the exact semantics of the most simple properties.
One of the problems, however, is that charging for a book signals its value. Whenever someone is offering something for free on their website, assuming I have no prior knowledge of the reputation of the author, it is easy to make me think that it is free because no one else wants it.
It would probably look better.
In both case quarantines were put in place and/or people were eventually evacuated. Yes, there is a limit where not 100% of the population will be infected. Given the R0 of COVID-19, currently herd immunity is thought to be reached between 60%-80% of the population getting infected. So even if we are generous and take the low end of the IFR we get 960k - 1.28M deaths to reach herd immunity.

There is some news out that is putting the IFR closer to .3% on the low end. That is great news if it holds up. The problem is that the numbers out of NY, if flawed would bring the IFR lower than reality, and they are ~.75% IFR.
OK, I might have a lead on the GCC versus Clang gap. At the least, this obscure command line option closes the gap:

gcc-8 -fno-math-errno -O3 bodies.c -msse3 -Wall -lm -o bodies_gcc_O3_sse3_c
perf stat bodies_gcc_O3_sse3_c 5000000
1,398,805,282 cycles # 3.691 GHz
3,181,041,562 instructions # 2.27 insns per cycle

I haven't thought about it much, but more info here: https://stackoverflow.com/questions/37117809/why-cant-gcc-op.... While the question is about C++, it hints that the spec might require sqrt() to set errno if given a negative number. Clang special cases this by adding a never taken branch, but gcc does not (unless told it doesn't need to care).

Much better dynamic range, which means you can throw a c41 roll in any camera with an half working meter and you'll get an usable picture. Over or under expose a slide by 1 stop and you're already asking for troubles.

Negatives are also much easier to scan than positives, and possibly easier to print but I'm not very familiar with that.

It used to be forbidden to advertise prescription medication in the US but they changed the rule sometime in the 80s.

The usual format is lots of images of happy people walking in parks and spending time with family while a narrator says the drug name a dozen times and what it treats, then reads off a long list of side effects and warnings “blah-blah should not be taken by pregnant women, women planning to become pregnant”, “blah-blah should not be taken by smokers or those with reduced immune function”, “blah-blah may cause liver and kidney failure”, “deaths have occurred while taking blah-blah”.

Personally that makes me want to go suck on a soup bone and hope for the best, but for the larger population the ads are apparently very effective and scores of people who see them will go pressure their doctors to prescribe them or shop around for a doctor that will prescribe them. (Drug store clinics will pretty much prescribe anything if you can articulate having symptoms it treats - conflict of interest is obvious)
Imagine you have a big wrecking ball swinging through the air at high speed, you throw a baseball at it and hit it head on. It seems intuitive that when the baseball bounces off it, it will pick up some speed from the wrecking ball. In turn the wrecking ball will slow down the smallest amount from the collision with the baseball.

This is effectively what a gravity assist is. It's a collision with the planet. Because gravity is a weak force, and curving around a planet takes a while, it's a very gentle collision. Regardless, the result is that you pick up some momentum from the planet, and the planet slows down very slightly.

All that gravity really assists you with is increasing the duration of the collision and reducing lost energy from the collision, as the same collision head on would impart the same speed up, but would destroy your spacecraft for a variety of reasons.

They should really call it a gravity bump or something like that.
