In an ideal world, sure. However many organisations run older machines because of large-scale investment in now-defunct technology, which they can't afford to re-invest.

There are absolutely non-boring mathematical books by Russian authors. In addition to already mentioned "Mathematics: Its Content, Methods and Meaning" by by A. D. Aleksandrov, A. N. Kolmogorov, M. A. Lavrentiev I would add "Elements Of Applied Mathematics" by YA. B. Zeldovich, A. D. Myskis [1]. The latter is really good introduction into math when one needs to apply it in various settings.

> Every shelter is for men by default. Women-only shelters are the exception and are far fewer in numbers

You're presenting that as comparing the situation for men and women, but it's not doing that.

You're comparing shelters that let in men (i.e. including both men-only and mixed shelters) vs shelters that only let in women.

You could just as equivalently switched the genders in the quote and it's be just as much true "Every shelter is for women by default. Men-only shelters are the exception and are far fewer in numbers"

EDIT: to all the people downvoting this, care to say what you think the problem is with what I've said?

Nothing with an Atom CPU will do H265 playback. It'll stream fine with Plex to a playback device that supports it, but I'm not sure what's out there that supports H265. Maybe some sort of Chinese Android TV box?

Good example of something (although it's perhaps a bit trivial) that is a puzzle that seems to make even non-mathematicians curious is the 'justification' for greco-latin squares.

The idea is that you have 6 files of 6 men. Each is of a different regiment, each is of a different rank. Is it possible to arrange them so that no row and no file have two men of the same rank or from the same regiment?

You can mention this in your first lecture on algebraic geometry (or, for that matter, combinatorial geometry i.e. matroid theory) and then come back to it when you talk about projective geometries.

Damn, that is a great quote. And I went and read late-Wittgenstein[1] to get that idea nailed down (admittedly with a hell of a lot more but he is not an easy read). His concept of "word games" is an excellent thinking tool to have available.

I'll go OT with you. Is there any attribute of 'the best cookbook' that you can remember that'd help us figure out which one it was/is - example recipes, cooking style, memories of the food made from it, or the book itself? Is the book still in the family?

I once had a copy of the Alinea cookbook, it's a wonderful object. For mere mortals like me, 'The Way To Cook', by Julia Child is the cookbook I refer to most often and suggest most often to those looking for 'the best cookbook.'
Transcript: Interview with Donald Trump
Regardless of how right you are on those details, taking it out on a fellow community member is mean and unduly personal.

We ask people over and over to assume good faith and not insinuate that someone is astroturfing or PR-ing just because you dislike what they say (or who they happen to work for). This sort of argument tactic is poison to community, and the strain of it you came up with here strikes me as virulent.

Large organizations are mixtures of good and bad—not equally, but not uniformly either. To lash out at someone because you're frustrated with what he probably had nothing to do with is uncivil and contradicts your moral posture. You can defend vulnerable people without abusing others personally.

If you want to keep commenting here, please give fellow community members the benefit of the doubt. Who knows?—maybe he feels exactly the way you do and you just kicked him for it.
And what about non-mobile computers, which are (almost) never locked down? Why single out mobile?

I prefer watching Netflix on my TV rather than a tiny phone screen, but if I did want to watch it on mobile, I'm a bit worried how they might treat my Fairphone.
> E.g., in those days there was a book on the natural numbers, that is, 1, 2, 3, ... that apologized for numbering the pages before the natural numbers had been carefully defined!

This was almost certainly a joke, although it must be said that it was probably more of a parody than a haha-joke.

The reality is that mathematics is written in a rigorous style because rigour is part of mathematics. You can waffle on for as long as you like about the intuition and the applications and whatever else, but you need to eventually get to the rigour.

The physicists and engineers might get away with 'drawing diagrams with little interval dx', but mathematics simply cannot.

Physics and mechanical engineering are not mathematics. Maybe don't try to learn mathematics if you want to actually learn physics?
All these stories are reminding me of m first encounter with programming. My Grandpa gave me his $600 Visual Basic (5?) book + software when I was 13 (~15 years ago). He didn't have the registration key, but I naively thought I could get lucky with a 16+ digit code. The first code I tried failed, but I tried changing the last digit and after a couple of tries got it. I didn't know what it was called at the time, but I instinctively guessed it could be a checksum, and somehow, that's how Microsoft protected their $600 product in 2002. Anyway, my Grandpa passed before I went to college but I think we would have had a lot of fun talking programming, because I was much more interested in pure math in HS when he died. That first programming book was definitely what got me interested though.
And when you fall asleep it hits you on the nose.
Wine has long been sufficiently compatible with Windows to run malware. I added a bit about this to the Wine FAQ in 2009 I think ;-) IIRC the ZeroWine malware analyser would run malware in Wine in Debian in a QEMU virtual machine.

The question here is not whether it runs, but whether it can infect.
You have it backwards. The theory is that they're using servers to heat the people.
"How to Catch Hackers"
People must learn the difference between hackers and cybercriminals.

Coal demand rose for most of the last 100 years, only recently peaking, jobs declined over most of that.

Automation and moving to surface mining (probably because it was more automatible so basically "automation") account for most of that change.

My experiences with EFF in real life in Europe have been abysmal. I tend not to donate to organizations that are contrarian by statute.
Especially so when you go to conferences, you hear panels where a EFF representative is chatting with a Google lobbyist and ends up using sentences like - and I quote - "OMG, you are so right", "Wow, I can't agree more". The theme was the censorship of content and a critique - clearly instrumental to Google's bottom line - that any content shouldn't be regulated by law.
The .w component clicked for me when I understood that it allows to transform 3D-vectors (describing a direction and magnitude, .w is 0) and 3D-points (describing a position in space, .w is 1) by the same 4x4 matrix. The translation part of the matrix is multiplied by the w component. Thus a vector (with .w=0) will not be translated, only rotated and scaled, while a point (with .w=1) will be scaled, rotated and translated.

All the esoteric projection- and 4D-stuff is really not that important compared to the simple feature of allowing to feed positions and directions into the same matrix operations.
I sometimes get the feeling that we seem to have taken a huge step backwards in math books over the past 50 years. Back when I was in college and studying multivariate calculus I happened to find a small, ~100 page, book called something like "Introduction to Multivariate Calculus" from the 50s in a used book store. This tiny books not only covered basically the whole curriculum of my course, but did it in much greater clarity then the 500+ page that was our textbook. I can basically thank that book for me passing that course. I find on the whole that especially introductory mathbooks have gotten harder to follow and less clear (and a lot longer) over the past few decades.
Ah, that's good. Thanks for the correction.
Doctorow has great ideas and is a great writer, but damn, he could use a better editor most of time.
Benefits of Big Data That Can Broaden Opportunities of Your Business
I'm in no position to guess which way winds are blowing but...

I don't think uber (or lyft) will ever be totally dominant purely because of network effects. Passengers and (especially) drivers are mobile, and can switch services back and forward between apps. All you need to compete is a regional network. The global network is helpful on the margins, but an uber for Lisbon should work fine.
Sure, lets ignore deplomacy failures and the CIAs misdoings in actually enabling and even partially triggering that pathway and make sure we endanger the whole planets network to get an edge in a war were too proud\patriotic to think differently about.

That way of thinking is whats making us need cyber weapons. Not to mention it shapes foriegn policy.
I'm really surprised there was no direct mention of the DMCA. That's turned out to be the thing that's given us un-repairable John Deere tractors and printers that won't use 3rd-party ink cartridges.
That's a nice sounding, appealing-to-read philosophy. But I'm not sure that it's actually true at all.
I think the point OP is making is that Uber doesn't really own anything outside mindshare. The drivers are after all free agents. Once the VC money used to subsidize rides dries out basically any company can challenge Uber.

Which is why Uber wants to cut their dependence on drivers by using self driving cars. Then they will actually own something (the technology) in addition to the mindshare.
That's a good point. At least here in Amsterdam I know a few people who avoid shelters if they can because they are/feel unsafe. These were all men, so I can imagine it might be worse for women.
> Mathematics traditionally has a macho ethos

Have you actually hung around with some mathematicians? I find them to be on the whole quite a humble bunch of people. My feeling is that any hubris is burnt up in all of the great suffering that it takes to do good mathematics.

I think the machos all migrated to physics in the first half of the 20th century. Those guys are full of "big talkers". Have you ever heard of a physicist refusing the Nobel prize? No, but it has happened (more than once i think) for the Fields medal.

Yep, but would you ever buy a device with such a feature, even though you hate compulsive smartographers at concerts?
That's the most egotistical thing I've ever read. It's pretty typical of physicists though. Whenever you see a 'scientist' on television pontificating about things they don't really understand (from psychology to economics to theology to whatever happens to be relevant) they're usually physicists.
Agree this is a problem; there are a huge number of worthwhile questions that get closed on stack exchange. This is because they prioritize the reputation of the community over answering all worthwhile questions (and to be fair maybe they wouldn't still be with us if they hadn't). Still most of the mods would do well to remind themselves of the official advice

Computer science is far from trivial. In fact, it's arguably the only part of mathematics that is provably non-trivial.
I should start using Uber more often if that is true.

Terabytes is nothing. If one movie is a couple of GB, a thousand movies will be a couple of TB. Since 1900, there have been on average 2500 movies released per year (the early years were quiet, recent years are closer to 10,000).

So 2500 movies per year time 100 years time 4 GB per movie is 1 million GB, 1000 TB or 1 Petabyte.

And that's just movies. If you also want TV shows, it's probably going to be several times that (though until recently, they were produced at lower resolution).

Still 125 TB is a lot.
>> I've always just sent a apologetic but firm email saying that I cannot accept those clauses and they always get removed

Hold on, everyone! My parent(^) said something simple, yet it is powerful. I don't believe s/he realized they were providing such insightful information, but the little gem that makes a huge difference is in that short quote.

While many companies may not be flexible with their contracts, I love your approach. Surely the odds of success must improve - if only slightly - by simply pointing out undesirable clauses and requesting that they modify and reissue the contract to accommodate, rather than striking it out in red ink yourself and shoving it back in their faces as an ultimatum.

The former tactic de-escalates the issue to being a reasonable request from a respectful person, while the latter comes across as coming from an immovably stubborn personality who may bring a habit of causing drama into the company. Better to politely identify how the employer can effect a positive difference on your end, rather than railing against the company's policies with your demands before you've even been hired. "My way or the highway" doesn't sound very amiable.

How often do companies reject red-inked contracts, not because they are unwilling to amend the contract, but because their intuition has triggered them into avoiding your coarse methods of getting what you want? Seriously, this is quite eye-opening. You've made me rethink my negotiation phase. I will be unapologetically thieving this diplomatic approach for my personal use in the future. Thank you!
I was visiting a local library 2-3 times a week and took out books like "The C Language" and SICP and slowly worked my way through them. It involved a lot of tinkering plus trial and error. Learning to program was less spoon-fed compared to today's norm and needed more dedication since gathering information and its synthesis took longer and was harder.
Although it is often the case that free software (or libre software, or whatever you want to call it) is available at no cost, the term "free software" generally does not refer to the price but to the given freedoms.
I've been trying to replace my MBP with iPad since the original and almost have a viable solution with the iPad Pro and the Razer Mechanical keyboard case except for two main things:

- Integration between apps is still not there. There's some good code editors out there with syntax highlighting and project based but none support git. There's some good git clients but there is no workable path between them and your coding environment without intermediaries like Dropbox etc, and none that share the concept of a project. You are at the mercy of the developers to support everything you need or to integrate with another (possibly third party) app. On MacOS there is always the lowest common denominator, the terminal which can glue any workflow together.

- The combination of iPad Pro and keyboard is bigger and thicker than a 13" MBP. Which would I rather take then...
What a coincidence. Just this week I got a used FX160 for 15 € and right now it's working as a home file server, router, wireless AP and general P2P downloader.

It seems to be running fine even inside of a closed cupboard, the CPU is at 31ºC and using about 16-17 watts on average. It's warm to the touch but it might be the apparently good thermal design of the case which allows for fully passive cooling.

What I don't like is that (at least judging by the heat it generates) most of the power consumption seems to be originated in the video chip, which in a headless server is useless. I tried to disable but didn't have any luck (it's a SiS 771/671 chip).
MathOverflow is not StackOverflow. For that matter, StackExchange mods in general are not 'appointed'. A very few are employees of the StackExchange company, but the vast majority are just normal people that have contributed a lot.

MathOverflow is intended for professional mathematicians. It isn't a general purpose discussion forum for mathematics. That such a thing doesn't really exist in a satisfactory form can't really be helped.

Well for one Turing was certainly somewhat interested in physics. From his WikiP page:

In 1928, aged 16, Turing encountered Albert Einstein's work; not only did he grasp it, but it is possible that he managed to deduce Einstein's questioning of Newton's laws of motion from a text in which this was never made explicit.

Then there was von Neumann and several others. If not interested then at least well educated in physics.
Its a flawed comparison.

- The value of Linux is the very thin cost of update (OS and applications).

- 1t the cultural level, *nix users are much more tempted to find solutions rather than keep dangerous attack surface running.

- Linux runs on old hardware easier, kernel supports old arch, user space is less demanding and doesn't tie you with graphical hardware capabilities for the sake of market share. Linux Mint XFCE is my go to graphical distro for anything even from the XP days (it's butter smooth on a LV 1st gen core + 512MB)

What I find most amazing about homogeneous coordinates is the duality between points and lines and their behavior under vector cross product.

Basically:

cross(p1, p2) = line_between_p1_and_p2

cross(line1, line2) = point_of_intersection_of_lines_1_and_2

To understand this you would need to dive a bit into projective space and how lines are represented there, but it is very enlightening.
There's no shortage of 'intuitive' books on physics or programming though, and those fields have no shortage of, to use your terminology, 'autists'.
