Since there's lots of discussion here about overstays, here's the US government report for overstays broken down by country:

https://www.dhs.gov/sites/default/files/publications/FY%2015...

Some highlights from the category of FY 2015 Overstay rates for nonimmigrants with B-1/B-2 visas admitted to the United States for business or pleasure via air and sea POEs for non-VWP Countries (excluding Canada and Mexico):

Bulgaria 1.48%

Romania 1.81%

Average of all countries 1.60%

The highest rates are Bhutan 23.98% and Djibouti 26.80%.

One important factor that the report doesn't give is the difficulty of getting the visa in first place. Some countries have a much higher visa rejection rate by American consulates than others. Those would be interesting statistics to see.

I couldn't find a similar report for Canada, but I'd expect the proportions by country to be similar, but perhaps higher overall for Canada since Canada is slightly easier to enter than the US.

Nah... they just ask the Fed to p00f money ( debt ) into existence so they can pay the bills with the no limit credit card. A little drama about the debt ceiling and everything is all better.
It mentions DLL injection in the article so it looks like the machine is running Windows.

This is one of the downsides of using a commodity OS for absolutely everything, you end up with edge cases where one size fits nobody.

Throw in that the people commissioning the systems are not computer scientists and/or applied mathematicians and you end up with this kind of thing.

I'm cynical, if I had to design a machine to draw lottery numbers it would look like the old style rolling tumbler machines (which is what we use in the UK for the lottery[1]).

If I needed to handle lots and lots of draws I'd keep the physical machines and use computer vision to handle reading the balls with a completely separate system recording the draw as well (so I have an audit trail) EDIT: In fact thinking about it I'd have two CV systems written independently by different organisations/teams with any disagreement halting the draw and raising a flag.

Setting it up so that the person who writes the CV code has no access to the physical machine would be straightforward enough and isolating the recording system from the rest as well.

Essentially no one person in the loop should have access to all the components otherwise this stuff probably will happen.

Oracle takes this to its logical extreme by allowing pre-queries that sample some of the data, so it can change the query plan on the fly if it's taking too long. It's a very powerful feature, but for many workloads it's not worth it. It's worth noting that better statistics and data sampling are usually more important to producing a great plan than exhaustively exploring, e.g., join order (especially for things like many-to-many joins).
It's very odd that a letter written in purely legalese terms receives a reply that is mainly hand-waving and pointless in the remarks that are made (as if all the details given by Brave/Eich weren't already known). Doesn't strike me as particularly brilliant, but IANAL etc.

I also wonder how long until Brendan Eich is just "Brendan Eich" and not "Mozilla former CEO". I can't imagine Mozilla is very happy with being associated with a competitor, especially in a situation like this.

What I mean is the EU is negotiating on the behalf of all Schengen area countries (including the Swiss, Norwegians, & Icelandic) but is not negotiating on the behalf of the UK/Ireland (who are EU members).

It has to be this way because when you enter the EU it is either Schengen or the CTA (UK/Ireland).

While technically Bulgaria and Romania are not yet in Schengen, they have to enter at a future time.

The Swiss, Norway and Icelandic visa policy IS involved because they also have to fill in the silly form and pay the fee to visit the US/Canada as part of the Visa Waiver Program or eTA but a US/Canada citizen can simply enter Switzerland or Norway (Schengen) without any forms or fees.

While Bulgaria, Poland and Romania have the WVP issue this isn't the only reason for these measures. This is on the agenda too (how they are not in the WVP) with the USA despite intending on being in Schengen.

While the UK/Ireland also has the ETA these negotiations don't have anything to do with it as they will not be imposing Visas on US or Canadian citizens.

People do not stay on Facebook because of its technology or features. They stay on Facebook because of the people they are connected to. I was in my 30s when Facebook came around, which was young enough to still care about, and be excited by re-connecting with old friends from school. The thought of losing touch with them all again made leaving Facebook a difficult choice. I eventually did so, but had to come to terms with the fact that I was dropping a large set of "friends" for the second time in my life.

Anabolic steroids are very useful for distance sports, but in a different way. They speed up recovery from micro-injuries, enabling cheaters to put in more training miles on the bike or running.

exactly. we should be trying to create a process of mutual respect. its a big decision for both of us, and if we are going to work together we should understand each other's need to get more information, look at other opportunities, and most importantly get a decision made so we can both get on with our lives.

if a company says, 'you have until next tuesday to respond to this offer', if it makes sense for me i agree, and if it doesn't i ask for more time (i.e i have another interview scheduled tuesday).

i also never take negotiating or career advice from a recruiter :)
The US trucking industry is ripe for disruption. The role of a driver is minimal as it is: s/he has to just steer the truck along the highway, with periodic fuel stops. There's nothing preventing an automated system from doing the same. Self-driving cars may be years away, but self-driving trucks which automatically attach themselves to trailers, drive 2500 miles and drop them off, only to do the same in return, 24x7 ? That'll be huge.

Don't ever reneg on something you signed. All these small defections to acquire a small advantage for yourself poison the well for anyone trying to act honorably.
The argument against ad-blocking is that the content-creators don't get paid for their content. But, honest question: who cares!?

If you push out content and you can't make money on it without ads, then that content didn't need to be created in the first place. The argument then devolves to "there won't be any good content" but I'll _gladly_ roll the dice on that world to see what we're left with.

Ads, to me, represent a monetization strategy rooted in "I did something, and you're looking at, so I deserve to get paid" but that makes no sense. The disconnect here is the presumption that the content has any value to begin with. I think what scares traditional content-creators is the idea that the vast majority of content has no inherent value.
doping is ALWAYS userful, doping allows the biggest advantage you can have: you can train more at higher intensities because your recovery is a lot quicker and you get injured less.

This of course also helps with the narrative of "I won because I trained super hard", some people are genetically blessed to be able to absorb large training volumes without getting injured or burning out, for the others there are plenty of things one can use to achieve similar effects

This is also why unfortunately some coaches seem to go through athletes quite a bit until they find some that can take the workload, and focus on those, not so good though for the ones that ended up getting injured and out of the sport though.

I do think the news tend to portray doping too much as "race day doping" when the biggest gains are made in the offseason, and this is why there are rules like offseason testing where athletes have to inform the anti-doping agencies where they are at all times, and why it raises a lot of questions when some countries don't seem to have effective offseason anti-doping controls.

Previous HN discussion of Knuth's email containing anecdotes of people's experience interacting with him: https://news.ycombinator.com/item?id=2537624
Found this little gem down the article, past the "eyes glaze over" point:

"Laptop users instead took notes by rote, taking down what they heard almost word for word."

This would explain why they're adhering to Betteridge's law of headlines: "Can Handwriting Make You Smarter?"

I'm going to dissent with the majority of commenters here and say yes, it provides a lot of value to its users. Why do you think so many startups are squashed because they're just subsets of Facebook functionality?

With the network effects of having over a billion people (and most of the developed world) on Facebook in mind, consider that all of these people now have free and highly functional voip/video calling wherever they have internet. They have a group and event management web apps with sophisticated privacy controls. Facebook also serves as an event and news discovery app. It's also an effective publishing platform, though the line between statuses and articles can be blurry.

Note that I'm not listing things that Facebook users can do, but things that I've seen Facebook users actively employ.

And all of this for the small (dollar) cost of giving up your email address and personal information. Which, for most people, as we've discovered, is an acceptable trade. Most people's personal information is not that valuable to them, given an agent that is trustworthy enough. Consider that most Americans give up their social security numbers on things as trivial as a job application.

In summary, outliers like HN commenters may disagree, but most people get a lot more value out of Facebook than they sacrifice.
Exactly! I'm interviewing with 2 companies and they both had weeks of interviews, and both finally decide to move forward, but take over a week to get the offers together. One has the gall to tell me that they require a response in 48 hours and speaks of internal SLA's, while the regional president of the other company calls me to apologize about how long their process takes and how thrilled they would be if I joined their company.
It's a thought provoking article.
I don't think recruitment policies and processes are given due consideration as a competitive issue by many business owners and managers. I'd expect that the impact of a team that is relatively less confident, less skilled in negotiation and potentially even less financially stable than their competitors would be very substantial.

You shouldn't do it because it's wrong, and as a result you should feel bad about yourself. You cheated at the game we're all playing and added to the general mistrust that makes negotiating employment so shitty in the first place.
I think we should be appreciative that there are people willing to debate the other side of this issue, or at least to try to lend some clarity to that other side, rather than being petulant when those people don't agree with us.

As important as these discussions tend to seem to us at the time, they are in fact awfully boring HN threads, because for the most part they're just nerds competing to see who can agree harder.

Beautiful story. Thanks for sharing.
You should politely ask them to send you a new offer letter with no deadline (and a higher salary). Don't whine, negotiate.
Schengen also regulates a shared visa policy for all members and all countries that are prospective members. This affects all EU countries other than the UK and Ireland, and indirectly affects several non-EU countries. E.g. Norway applies Schengen visa rules as a Schengen member, and non-Schengen countries that are prospective EU members works towards harmonising their visa rules with Schengen because it is a requirement of EU membership.
Or how about short-circuiting it?

A "witch hunt" is going after someone unfairly. Maybe they're personally unpopular. Maybe they hold an unpopular view. It implies injustice. I don't see that here.

This woman has apparently been fairly well proven a cheater. And if you regularly cheat in order to win a relatively major sporting event, you run the risk of the New York Times writing an article about it -- and maybe sending you a few e-mails or knocking on your door to get your side of the story.

The people who deserve sympathy are those racers who played by the rules but got fucked out of a spot in higher-level races because of this woman. And the people who actually won those races but didn't get to enjoy their moment of celebration at the top of podium. Small things, maybe, but nevertheless it's shitty that those experiences were stolen from people who worked very hard for them.

One of my favorite podcasts, Hidden Brain, had a great episode this week about "Grit", which one of the researchers defined as "passion and perseverance for long-terms goals."

"The thing that was revelatory to me was not that effort matters—everybody knows that effort matters," Angela told Shankar. "What was revelatory to me was how much it matters."

I still think there's this question of "why do some kids have more grit than others?" to be answered, but perhaps this is a start?

> It remains to be seen if SpaceX can reuse rockets in a more cost effective way than the shuttle.

Given that the launch cost of a Falcon is already way less than the reused launch cost of a Shuttle I think if they can get 3-4 launches per rocket they'll massively reduce the cost to put stuff up.

They already have done that anyway, they undercut pretty much everyone who is currently launching, sometimes hilariously.

Musk said in one of his speeches to congress (iirc) (paraphrasing) "Our launch costs are so low that the cost of launch plus the satellite is less than ULA's launch cost alone, so you buy a launch and get a satellite for free".
The value of Mathematica is pretty straightforward. The language it provides is nothing special, but the scientific and mathematic routines, along with the symbolic support, put it in a class by itself- no open source package I've seen does root finding and other similar processes as effectively.

The symbolic stuff is pretty cool too. Years ago I wrote "pyml" which made all the Mathematica features available in Python via a C language bridge. Whereas in scipy/numpy you can find the eigenvectors of a numeric array (a matrix of floats), in Mathematica, you can find the eigenvectors of a symbolic array (a matrix containing terms like x-1, y-5, etc).
I tend to remove them because trailing commas break JSON. The similarities between JS and JSON are small enough for me to get confused over it and I'd rather remove the cause of potential errors there altogether.

I raced bicycles in the 1980s and duathlons in the 1990s. By the 1990s, drug cheating had become rampant at the professional level and was seeping downwards into amateur sports.

I have stayed in touch with the sport, and it’s especially filthy amongst the age-groupers. They have no financial motivation not to cheat: They are already well-off and won’t lose a penny of sponsorship money if they get caught.

Furthermore, many come from the world of business, where cheating is a fact of life. You do a certain thing, if you get caught, you hire lawyers and fight and/or bargain your way to the least unfavourable outcome.

What is the difference between offshoring your tax avoidance and visiting a shady doctor for a prescription? This is especially true when it reaches a certain tipping point where “everybody cheats.”

Like many things in life, there are two sets of rules: One for those with a lot of money, who sit on the board of their local club and/or sponsor the racing scene, and another for those who ride purely for fun.

For a certain type of middle-aged type-a male, it is about being the “Alpha” in the scene, and that means winning your age group at all costs, having your business’s name splashed over everything in sight, and that means being a part of the power elite within the sport itself.

I’m no longer a part of the multi-sport scene, I switched to mountain biking, where I thought I’d find a laid-back outdoorsy California vibe.

It is there, if you look past the guys with a “quiver” of six or seven carbon-fibre bikes :-)
