Cmd+Q would be my first action in that situation (which I’ve been in!) But I agree not everyone knows that.

I was imagining someone wearing a glove, but you are right that a certain amount of water will start causing issues. I think it would be difficult to pool enough water on both the touch bar and the trackpad outside of a catastrophe.

I can’t get sound to continue emitting after closing the lid. I’m sure an app can be developed to make that happen, but it wouldn’t be something commonly used. The most likely candidate seems to me to be something like audio performance software, but a person in that situation wouldn’t be using the speakers as an out and would be used to quickly dealing with software/hardware quirks.

Researching this conversation has been fun. :)
Why Did Artificial Intelligence Fail in the FIFA World Cup 2018?
I'd recommend you look into the Raspberry Pi, Arduino, or micro:bit - each offer a great introduction to physical computing with huge libraries of online content to dive into.

https://www.raspberrypi.org/ <-- Basically a pocket sized computer which can run a full Linux stack and exposes a heap of useful IO options.

https://www.arduino.cc/ <-- More akin to embedded systems - traditionally very low powered micro-controllers programmed in C.

https://microbit.org/ <-- Designed specifically for education and provides a number of high level abstractions for development including visual programming languages and MicroPython.

As well as these there is a huge range of other options targeting different niches such as Javascript, Internet of Things, ultra low-power systems, etc.

It really depends what you're interested in getting into. All of the platforms have starter kits, add-ons, and tutorials to get you going. Feel free to message me (e-mail in profile) if you want to discuss further!

To an extent, it literally doesn't matter. If I fabricate a video and splash it around Facebook, it won't have a signature. Maybe Facebook will put a "has a signature" icon next to videos that are signed... but remind me, how much do web users notice when a website is HTTP vs HTTPS? Anyway, if a video is fully fabricated, there will be no hash to compare it with. And, by the time anyone does, it will already have been remixed and spread across Facebook.

There will be lots of good reasons for a video not to match bit-for-bit from CSPAN- if I add commentary on top of it, or intercut it with other clips Daily Show style, or just re-encode it, the hashes won't match. False positives are the death of an indicator, and there will be far too many of those for this sort of scheme to work.
> compilers ... replace the computational algorithm, written by a human, by a more asymptotically efficient one.

Andrew Appel in Compiling with Continuations gave an example of this. I forget exactly how it went, but it was something like this:

(define (range a b)
(if (> a b)
'()
(cons a (range (+ a 1) b))))

(define (sum xs)
(if (null? xs)
0
(+ (car xs) (sum (cdr xs)))))

(define (triangle-sum n)
(if (= n 0)
0
(let* ((xs (range 1 n))
(triangle (sum xs)))
(+ triangle (triangle-sum (- n 1))))))

The triangle-sum program, which adds the triangular numbers from 1 to n, will, as written, consume O(n^2) space, because it creates the list "xs" of length n before recursing down to n-1, and the list will not be freed until the entire computation terminates. An optimizing compiler might discover that, once it's computed "triangle", it can discard the list "xs"; this would reduce the required space to O(n).

Hoisting a computation like (length <list-of-length-n>) out of a loop can similarly reduce the time taken from O(n^2) to O(n).

You summarized my thoughts pretty well. I would have thought it obvious but I forget sometimes what a hypersensitive world we live in, and how quickly some want to rush to judgement.

Please define what "making full use of it" means, without referring to profit.

Because without that definition your sentence doesn't actually say anything.
Part of me really wants this because it brings access to all of the world's people that can get at a computer with the appropriate transmission and reception device and would allow people to be able to easily get information out when under the threat of a hostile government.

> Outlook is one of the best mail clients out there, not many can disagree about that.

Outlook may be a fine program for some types of office work but its MUA is one of the absolute worst mail programs in existence, surpassed only by certain webmailers and a collection of weird mobile apps handset manufacturers are probably paid serious money for shipping pre-installed on their (low-end) devices.

I have never seen a mailer being so actively destructive to email. The only times I receive mail that is more garbled and/or broken than that from Outlook users are the creepy web and mobile apps described above.

I have no idea whether all of this is the result of configuration errors on the user side. Maybe it's actually possible to configure the Exchange/Outlook combination to behave in a sane way. If so, this knowledge appears to be awfully rare among the Outlook- and Exchange-using population.
Would be incredibly awesome to see POWER9 options on Google's public cloud VMs…

Meanwhile, ARMv8 is already available to the public!

packet.net offers access to a full dedicated dual ThunderX box for $0.5/hr (or 0.1 with spot instances).

Scaleway offers KVM virtual machines (also on ThunderX) for as little as €2.99/month (€0.006/hr).

First gen ThunderX kinda sucks at single-thread performance, but you get many cores and… well, you get to start using non-x86 machines, on public cloud, right now.

If developers start actually using ARM boxes for their projects, the providers will be more likely to expand in this direction, and maybe in a year (or less?) we'll see the much more powerful ThunderX2 boxes available, and hopefully more providers will get into this…

Is it too unreasonable of an idea for Uber to eventually force in-car CCTV (i.e. a reversed dash cam) for all rides in progress?

Seems like it would solve a lot of the he said / she said arguments discussed in the articles, at a relatively low cost footprint. I guess economically, the cost of 'fraud' would have to outweigh the cost of dash cams.
> fiddling with information _as such_ and in theory doesn't use up any energy.

that's not true at all. Any time you destroy information (for example an and gate can destroy information) you use energy.
U2F addresses phishing and password theft. TOTP just addresses password theft. That doesn't make TOTP useless; password theft is a serious problem, routinely exploited in the real world.
> that doesn't mean you are profitable or making a living wage

These statistics are tracked to a pedantic level of detail by the BLS. You can get numbers of people by industry and zip code and earnings bucket and quarter for most categories of self employment going back to the early 1980s. Moreover, unemployment isn’t mean to measure if people are getting a liveable wage. It measure if they’re getting any wage. The problem you cite is an issue, but it would quickly resolve itself into unemployment as the cash stores ran out.
> In this case, getting advanced STEM degrees provides a path towards residency, work rights, and perhaps eventually a green card or citizenship.

At my very first job, nearly all of my coworkers were Indian. As I met more people at work and started adding them on LinkedIn, I noticed one thing in common with all their LinkedIn profiles: they all got their bachelor's in India and their master's in the US.

One day, I was riding either to or from a company lunch with a coworker, and we started talking about our lives. He asks me about my education, and when I told him I only did my undergrad and never went to grad school, he told me that in his case, he had to go to school here as a condition of getting into this country, and since he already had a bachelors in CS, he went for a master's in CS.

This was before I learned how fucked-up our immigration system is. Once I learned that, his words made so much more sense.

Check out /r/leanfire and /r/vandwellers. Plenty of people in the process of bailing out on high-paying jobs as quickly as possible for retirement or just a simpler life. Occasionally someone that has already done it.
Yeah, it’s a very self selecting crowd.
If what we're interested in is genetic causation then the relevant comparison is to John if he was still shorter but joined the basketball team anyways. In that case the variance between their skills would be less and yet no genes were changed. That illustrates that the original difference wasn't due to genetic but rather environmental factors.

>That the causal pathway of the genes goes 'outside the skin', as some people put it, makes no difference that makes a difference for this particular question.

When genes cause changes 'outside the skin' the way those outside changes affect your skill are environmental changes by definition. For example you're saying that in our current society, where you can choose your extracurricular activity, the difference in their basketball-skill that's attributable to genetics is x. But in a different society where high school basketball practice was state mandated the difference in their basketball-skill that's attributable to genetics would be y where y < x. The difference between x and y can't be caused by genetics because we haven't changed any genes so it shows that we were just misestimating genetic causation to begin with.

I binge eat when I'm on Ambien, and have intense food cravings. That night I didn't have food, and there was a McDonalds about 5 minutes away from where I lived. I crashed into a stop sign three blocks into it.

Even as an anonymous poster, there are stories that I am too ashamed to even post about. If anyone sees this, and had some inclination to try Ambien recreationally, don't even try it. What's worse is that even after destroying every relationship I've ever had because of Ambien, I still can't quit it.
I'm going venture a guess that if anyone charges back against Uber, they're summarily banned from using Uber ever again.

True! A lot of people use Linux and the ecosystem because it's free. And that's a good thing! It's great to have this open alternative where people without economic resources can rely on solid systems without having to worry about licensing and stuff.

On the other hand, I try to pay/donate for products I use; my distro, Wikipedia, whatever.

I think this is something that those who can should do more, we usually complain about advertising and personal data mining but in the world we live on those are the things companies need to do to offer free services!

Unless we're delusional that we're gonna change the whole structure of our society, then we need to directly pay for our stuff! No matter the amount, support the main projects you rely on with cash!

For a research position? In my experience (on my third position now) Research Scientist interviews in industry tend to mirror academic interviews. 60-90 minute job talk in front of the research group, 5 or 6 hour long one-on-ones with members of of the research group. No mention of fizz buzz in any of these interviews, and I've interviewed at Facebook, Adobe, etc.

You could venture a guess, or venture into the article itself to find out.
My view has been they are looking for people with high IQs exclusively. Whiteboard interviews cut out people who are not even intelligent enough to memorize solutions and algorithms while also accepting people smart enough to come up with solutions to tough problems they haven't seen before. It seems given how much I struggle I may not even fit in the memorize 300+ leetcode category.

I'm very interested in this divide between people who are for white board interviews and against it and how it correlates with job performance and content. I may make a separate post about it because I'd like to get to the bottom of it.
This doesn't sound half bad. How can I find these?

> are there poker competitions that use braille cards ?

I did once enquire at the local casinos (UK). They were concerned about cheating or card tampering, even though they would obviously be purchasing the brailled cards, not me. I guess they have certified suppliers or something. Then again, this is the gambling industry so it's easy for them to shut down questions like this without having to do much explaining. I once contacted PokerStars to ask about using my screen reading software to access their platform, and was told it wasn't allowed because other players may hear my cards. Other players who are physically nowhere near me would hear text-to-speech coming through my headphones. The loopholes they jump through for tax purposes often mean they're also completely outside the scope of equality laws.
The Digital Computer:  Where does it go from here? (1954)
I don't know, I guess I just don't see it as a real story when so little customers are reporting it as a problem. Esp when all the customers referenced in the story itself didn't even have to do a chargeback. Yeah, it was a hassle with some emails back and forth, but Uber eventually took care of them all (at least the ones referenced in the article). I've personally never had a problem at all disputing a charge from Uber (I use the service every day for work).

That was kind of my point, was it not? QR Code might or might not have too much redundancy (depending on how resilient you want to be against what amount of sharing), but the general principle stands.

Lossy compression removes information by design, you want to keep all bits of information, therefore you have to represent your information in a redundant (and therefore inefficient, by density) way.
Let's say we found a way to make water the fuel of the future (that is used for all (most) of our needs), should we use it? Isn't water (one of) our most precious resource? Should mankind really risk using (wasting) our precious water? Well, we wouldn't loose it if we use it on earth, but space would be a different story (although, if we only use water as fuel for spacecrafts... it would take a while before we deplete the earth of it). What are your thoughts?
> Do you have any interest in learning other cues you could send?

Of course, I'm always interested in communicating as best I can. Not sure what you had in mind though.
It's just surprising to me the article didn't reference any customers in your case that HAVEN'T been refunded. All the ones they mention in the article eventually got their refund. It doesn't really make it look like that big of a deal in the article. Would help their argument if they included people haven't been able to get a refund, like yourself.
I took ambien for a few weeks in grad school. I had to stop.

1) They say it's not habit forming. That may be true. But I intended to take it during the week, when I needed it most. On the weekends I wanted to stay up a bit later (not crazy, midnight versus 10pm. However, if I didn't take the ambien by 10:30pm I'd start to get a vicious migraine, that first weekend without it was miserable. I took it for a couple more weeks but the same thing happened each weekend.

2) About half the time it had no impact on me. I was wide awake and concious the entire night. Not able to focus well (entirely unproductive), but awake. I'd even eliminated caffeine by this point in an earlier (and ongoing) effort to counter my insomnia. But if I took it at 10 and hadn't fallen asleep by 11, I knew I'd be up until the next night.

3) When I did "sleep", there was a 50/50 chance I'd wake up with abs that felt like I'd been doing crunches all night long. I don't know what I was doing. I felt rested, but man was I sore.

I continued therapy and quit grad school in efforts to deal with my anxiety, and only after that was my insomnia properly dealt with. Which is a reminder, treat the condition not the symptoms.

I learnt from this thread that my smart watch (Garmin Vivoactive HR) also has 2FA apps available for it (e.g. https://apps.garmin.com/en-US/apps/c601e351-9fa8-4303-aead-4...). I love the watch (long battery life, tons of apps including one from the famous antirez, built-in GPS, etc.) so I am thrilled that I have 2FA options for it as well.
Wouldn't the authority have to be the device manufacturers?
I friend of mine got a PhD in Electrical Engineering, which took him 7 or 8 years years. Right around his 30th birthday, I remember him saying that he'd been in school since he was 5. When I think of it that way, if my 20-something self could have been paid to delay entering the working world, I enjoyed school, and I was willing to be a professor's minion, getting a PhD would have been an extremely attractive option.
I am having hard time understanding the problem articulated in this article. Can someone with English as first language summarise the actual technical arguments ?

For example I see that there is one graph with part-time, full-time graph. The full time employment has increased rapidly while the part-time graph remains the same. How is that possible ? Also, sharing economy is a new thing where a lot of people who would be "unemployed" in past are now doing part time work. A lot of work can be done online today staying at home and hence more people might have taken up part time work.

Another graph shows how part time and full time wages have grown and it claims part-time wages have been stagnant. The graph does not show that.

In other words, you began your research with conclusion already in mind, and then looked for a way to present this data to show this conclusion.

Excellent statistical work. That's exactly how such research should be done.
It would be nice, but for complicated systems in the kernel you sometimes have to provide evidence that the old way sucks and the new way is better. With this work we can easily point at our production workloads and say the in kernel oom killer sucks and this new way is obviously better and hopefully work towards a better in kernel solution. That being said the user is always going to know what they care about more than the kernel, so being able to say “kill chef first, alway” can be a nice thing to have.
