I've thought of this but it usually takes some time to overwrite a lot of data. I'm not savvy enough to know if there's a way to nuke the data that quickly, other than non-software methods.

A friend of mine used to keep a massive electromagnet in is PC tower, that would theoretically wipe the hard drives when switched on. We never tried it. (He wasn't dealing in CP, just pirating mass quantities of movies and music).
> The argument made in the article is that it's a "foregone conclusion" that there's child porn on the drives, so decrypting them isn't self-incriminating because they already know what's on the drive.

The immediate thought that comes to my head when they say this is: Then whats the problem? You can prove it, so why do you need more proof? Unless your possibly maybe your case isn't rock solid or you want to find more crimes.

This is great but it would have been even better if Distill was designed to play well with the current system. Vast majority of researchers are focused on publishing at various conferences with strict deadlines. Even if they had all the skillsets and time to produce these beautiful illustrations, I highly doubt this will change.

Also, it is very likely that veterans in the field might think of this format as too verbose and too sugar coated, more appropriate for less math-savvy users and therefore not mainstream. Furthermore, I really feel TeX is irreplaceable unless you got all of its feature covered. All of the historic effort to replace TeX - even with bells and whistles of WYSIWYG editors - in research has failed and its important to learn from those failures. You will be surprised how many researchers insist on printing out the paper for reading even when they have access to tablets and PC.

Instead of being another peer reviewed journal, Distill could act as the following:

- platform to publish supplemental material and code

- platform to manage communication/issues post publication

- platform for readers to invite other readers for peer review and generate "front page" based on some sort of reviewer trust relationship.

- platform to host Python and MatLab code with web frontends without researchers having to learn new developer skills

- support pdf submissions but without all the eliteness of arxiv and using algorithms to create the "front page" based on some sort of peer reviewer rankings.

Above features are indeed sorely missing and Distill has good opportunity to become an "add-on" to current academic publishing systems as opposed to another peer reviewed journal.
> Yes, two bodies create a gravitational wave that affects other bodies - but I don't see how those variations represent work - and they aren't observable on the two bodies themselves, so one wouldn't expect any effect upon those two bodies

The lost energy results in orbital decay, eventually leading to the two bodies colliding. The page I linked to explains it in more detail.
New York City never tried. The lady our mayor hired as the city's CTO [1] is a telecom lobbyist. She worked at a bank for a short stint and was fired after signing up a couple departments for $200-plus a month voice-only phone lines. Her first accomplishment, in the administration, was giving our public schools the same treatment.

Neither are really known for their padlocks, and they're both pretty hard to find at retail - at least in North America.

for a reasonable priced lock (~$20) - I'd suggest American (probably the 1105) or one of Abus' mid level locks. Either are available on Amazon.

For "it'll be easier to pry the door off the locker than break the lock" level locks (~$100) - I'd suggest Abloy (330 or 340) or Mul-T-Lock.
These are harder to find locally - https://securitysnobs.com/ seems to get recomended on the lockpicking reddit if you want an online vendor.
Abloy's "Protec 2" lock design is one of the more well regarded out there- I'm not aware of any credible public claims to have picked it, and short of an angle grinder you won't be getting through the larger padlocks.

Trivia - the lock industry is very heavily consolidated behind the scenes, with several companies owning most of the major brands: "Assa Abloy" owns, besides the two companies in the name, Medeco, Yale, Mul-T-Lock, Fichet, and HID - who make the most common RFID security cards. Master Lock owns American Locks.

Indeed I didn't read the sentence correctly my apologies.

However, I don't see that as a vote of confidence in them since they are still permitting flights.

I think similar could be said of the TSA in the US - the DHS trust them enough to let passengers who have gone through security bring shampoo as carry on but not enough if those shampoo bottles are greater than 3.4 ounces, despite having gone through their security.

I think its less about a vote of confidence and more about absurdist theater.
I have been following up "awesome" posts with less-awesome posts for a few years now. It sometimes feels weird, but my experience is that sometimes off-the-cuff short posts are surprisingly popular, and that even when a blog post isn't popular, sometimes, a year later, somebody I really respect will tell me that they loved it.

for example I worked for weeks on this post: http://jvns.ca/blog/so-you-want-to-be-a-wizard/ and then followed it up with a few very quick thoughts on careers in http://jvns.ca/blog/2017/03/17/career-narrative/. My thinking is that people who read my blog can decide for themselves what to read and what to skip.

My only guidelines for blogging that I follow are basically these: https://twitter.com/b0rk/status/823183090554126336.

> There are plenty of programmers for whom this is cryptic

I've never really done functional programming, and map was cryptic the first time I saw it, but it's literally a concept that can be understood by any competent programmer in under 30 seconds - apply a function to every element of a collection and return a collection containing the results.

I don't have any sympathy for programmers who find simple abstractions like this cryptic but then don't try to understand them.

I see many people here trying to puzzle out why electronics are under a partial ban from cabins but not from checked baggage. It's a good question, since if there is a fire or explosion hazard on a plane the last place you want it is wrapped in a wad of flammable cloth and synthetics, even if it is oxygen starved.

The only motivation I can imagine is: They want these devices in checked luggage because checked luggage can be inspected without recourse by customs, and without an on-site confrontation. With care, it can be done without even notifying the people who are being checked.

And given the pushback on social media credential disclosure and the reveal that the CIA (and presumably FBI and other agencies) have physical access exploits (probably via USB or DisplayPort) for most of these devices, this seems like a move who's only logical motivation could be easier digital inspection.

Remember, it's the position of the TSA and CBP that non-citizens don't have rights of any kind until they're allowed through customs, and by simply inspecting devices they're interested in quickly and without publicity or confrontation they will certainly be more effective at it.

I'm going to start putting a USB nuke stick in my luggage in an envelope. Just for fun. Maybe I'll label the envelope something nonsensical like "12-16" just to make sure people know it's useless. And in case I (or someone investigating my luggage) needs to plug something into a USB slot.

The critical question is, why haven't they charged him? It is disingenuous of them to bring up the evidence they currently have essentially in an attempt to demonize him. Their evidence is sufficient or it isn't; if it is they should charge him; if not they're demanding self-incrimination.
Agreed on all points.

There are already plenty of per-seat licensing models that explicitly acknowledge bots - e.g. Perforce's "service users" (used for e.g. the heavy hitting CI build accounts that have more activity than dozens of engineers combined) which don't even count against seat limits. Per seat is just a way to charge roughly by organization size, which has some semi-linear correlation to SaaS usage, even if automation / "AI" adds a potentially large productivity or load multiplier.

Even if "AI" somehow breaks that assumption at some point, where one engineer can reasonably use 'infinite' resources, it's pretty easy to couch usage based pricing in the veneer of seat based pricing. Just apply rate limits per user - say, high enough to handle your 95th percentile customers - and offer "virtual seats" for the power users who want to increase their API rates, or require a higher tier "enterprise" accounts - just as existing SaaSes already do, complete with public documentation of some of their API limits right on the pricing page no less.
I'd break it more along old-young lines than black-white ones.

Medicare dumps so much money into the market indiscriminately that it's the primary reason our per-capita costs are almost double that of Western Europe, even though we do not have universal coverage. That, and as an age demographic instead of a national one, the aged are much much more costly to insure.

The coal job remark was particularly poignant. The state of Kentucky has a population of around 15M, but only 6,000 active coal jobs, but you'd never guess that driving around Eastern Kentucky. Many yards, and almost every other car has a strong pro-coal political statement. The heyday of coal must have been something else for them to still be burning the torch for jobs that disappeared a generation ago. They all blame it on Obama when the real culprits have been higher lamp efficiency, fracking, and cheap natural gas.

And for ease of reading, I'll reply to my own comment with other interesting issues:

* "The fact remains that the government has not brought charges," [his attorney] Donoghue said in a telephone interview. It seems a warrant is at issue, if I understand correctly.

* The contempt-of-court order against Rawls was obtained by authorities citing the 1789 All Writs Act. The All Writs Act was the same law the Justice Department asserted in its legal battle with Apple

* The authorities, however, said no testimony was needed from Rawls. Rather, they said, (PDF) "he can keep his passwords to himself" and "produce his computer and hard drives in an unencrypted state."

* My completely amateur thoughts: If they already can prove he has child porn, then they don't need the additional evidence. If they do need the additional evidence, then he is incriminating himself.

You got the prize. Everyone here is trying to attribute a safety reason. This is HS bringing down their budget.
I had a colleague fly through Amman last night. They had him remove 100% of everything from his briefcase and checked everything for bomb residue. If I had to guess, the US has intelligence that someone is going to bring a bomb (or some other weapon) on board a plane using a Laptop Form factor. I'm also guessing that the type of damage one can do with a device in the Cabin is greater than that can be done in the luggage hold (which is why the Laptop can be checked, but not brought through carry on.)

Though, I'm open to the alternative theory that having people place their laptops in checked luggage gives them greater opportunity to do targeted surveillance without their target being aware.

What about roads and water? "According to a report for the World Bank, average road density on the continent is 204 kilometres of road per 1000 square kilometres of land area – only a quarter of which is paved. In contrast, the world average is 944 kilometres per 1000 square kilometres with more than half paved." [1]

Not that I expect a YC company to solve African roads...

You really need to learn about Bill Gates before you judge him and publicly express your misguided views. Bill Gates has committed to give all of his wealth to philanthropy over his lifetime, leaving only $10 million for each of his 3 children after his demise. That means $30 million of his (current) $80 billion networth is all that will be left for his family whereas the rest goes to charity. That's philanthropy of over 99.999% personal wealth donation. I think by this he satisfies your 100% donation criteria.

You say that a person who gives 100% of his wealth to charity is bigger than one who gives 99%. The amount matters, not percentage. If Bill Gates had your mentality, then at which point do you think he should've given away 100% of his wealth? When he made $100 million or when he made $1 billion? Be reminded, if he had given up 100% of his wealth at those figures, he would never have had any significant money left to increase his wealth, so all those charities and research efforts of his that have received $30 billion+ of his wealth so far wouldn't have existed (the figure was $28 billion in 2013, don't know what it is now).

Bill Gates knows the value of creating value. He knows its better to teach fishing than to give fish. He invests money in research instead of just giving it away blindly because he knows that the outcome of that research will save/improve more lives than giving that money away directly. Again, he also knows that giving away all the money now isn't a better idea since as science progresses, better research will come along that'll need his funding, so he's keeping enough wealth to support those venture if and when they come along. If they don't come along during his lifetime, all of his wealth will anyway go to charity after his death (except $30 million for his children).

His business practices were cutthroat, but that was back when he was younger and not an active philanthropist. As a philanthropist, I think he's the greatest person of all time. Numbers matter, his billions have done more for mankind than misinformed people like you will ever care to admit. So go do some research before you bad mouth him ever again.

The chief data scientist at my last job said a Data Scientist knows more programming than your average statistician and more statistics than your average programmer. There's this venn diagram he used to show with the intersection of skills for the different disciplines involved - some math, some engineering, some communications.

I think there's also an intersection with devops skills, maybe less important, but your hardcore statisticians usually put zero thought into operational considerations. Really the last bastion of "works on my machine" thinkers in the computing world. I just finished the Coursera "Reproducible Research" course and I was really struck how many of those principles parallel good software engineering practices - use source control, document through code, separate your environment from your code, automate as much as you possibly can, etc. I've been a software engineer for 20+ years but I want to get into data science partly because I've always been a data head, just without the theoretical background to do really interesting work, but also because I think I can bring some of the software engineering skills to bear.

Also, with grading peer's work on Coursera, I really realize that a lot of these candidates need help with their English and presentation skills. Many of the students put no work at all into the presentation, I imagine that's going to serve them poorly in the working world.
Joking for sure. When I flew domestic in China people were using their phones the whole time.

> Lots of comments here seem to think this should be unexpected or is a bug. Closing a FD you are using is a bug. I think epoll does a fairly good job of letting the user know that it is watching the description and not the descriptor.

Then why is it reporting events for the file descriptor (not description) that was closed? Am I misunderstanding that?

There's nothing wrong with dup'ing an fd and closing either the original one or the second one while continuing to use the other. It's very strange that something would emit events on the fd that was closed.
I'm toying with the idea that tears are the direct result of excess CSF pressure (i.e. a way to vent that), having observed someone with that condition who tears very easily. Just maybe. This would presumably require that the lacrimal fossa be connected to the inside of the skull, which is certainly possible. Humans, the only upright animal, have unique fluid pressure problems within the skull (except for giraffes - maybe they cry, and nobody's noticed) so crying being unique to humans wouldn't be too surprising. One tiny bit of evidence, a study showing valproic acid ratios (in those taking the drug) are about the same in both CSF fluid and tears:
https://www.ncbi.nlm.nih.gov/pubmed/6799283

Of course, crying being a signaling mechanism is another explanation. Maybe a better one.

The only other connection I can make is that migraines are closely correlated with dry eyes (and emotion can trigger migraines.) So people with migraines are sometimes advised to use eyedrops to reduce migraine incidence these days. Lacrimation is also a migraine symptom. If your brain is very active due to emotion, maybe tears help to reduce the chances that migraines result? (Or returning to the first hypothesis, maybe CSF pressure is elevated during migraines.)

Not a disproof, but chimps are more socially sacrificing than this article indicates, they will find crippled chimps for long periods, as a group; IIRC not just relatives.

I see comments like this all the time. What people have to realize is all these shithole companies would act like this if they can. In the south, you can hear the same story time and time again with Time Warner Cable -- "Man when <insert anything else> comes, I won't be a TWC customer anymore." What needs to happen is the monopolies need to die and we need fair competition in the broadband space. This has been proven where Google made a footprint. All of a sudden, in fiber towns, AT&T or Verizon, or TWC started to offer decent speeds at the price. 50 dollar internet was actually worth it.

Anyways, these companies are all the same. They will milk it as long as they can until they are forced to change.
