Your assumption is false. There have been a few notable cases of flight-over-water crashes in which the correct zone wasn't found quickly, but in the case of flight 137, ships were over the presumed crash zone within hours of the aircraft turning up missing.

In other cases, particularly where the crash itself was visually observed (US Airways 1549, Ethiopian 961, and others) where a multi-day delay in starting pingers would have been counterproductive.

It's also useful to realize that any change you make on flight recorders applies to all equipment, needs to be replace on existing aircraft, and concerns a system which has to work with very high reliability.

EXERCISE outdoors. If you are not getting outside, you are likely low on D3. If you are not exercising your brain function will decline. 3 one hour sessions will make a big difference. just go for a walk or a hike and build up from there. the exercise should be strenuous to some degree and cause stress. the physical stress response and your overcoming it will have many positive side-effects in other areas.

seduce your girl friend more! it's a practice. strap her in a chair and lick her pussy until she is a quivering jelly. take her on a hike to a beautiful view. go play in a fountain with her. give her an adventure without any money and without a video screen. the creative and physical challenge of doing this for her enjoyment and for your pleasure with her will enhance your quality of life and enhance your ability to focus. One date per week, you and her alone having fun. no excuses.

go dancing and to parties where you socialize, not where you drink. social events like this will enhance both your own feelings and your relationship with your gf. You don't have to "like" these things, they have positive effects for all human beings whether extroverts or introverts. also, tell people about your startup as "what you do". Ask people what they do and what they struggle with. This can open up opportunities for you to help them.

learn more about the world. There are bigger issues and problems than yours. go look at them. this will help for the last and most important thing you must try to do:

PRACTICE GRATITUDE

A practice of gratitude will free you from the drudgery of your startup and help you to see it's advantages and fun in new ways. "I am so grateful for my GF because...." "I'm so grateful to be facing these challenges in my startup because..."

When you train yourself to orient around gratitude, both your happiness, productivity, and clarity will increase.
What about cars where you can enable/disable features like traction control and auto-break from the entertainment system? They must have some sort of connection, and that connection probably has bugs that could be exploited.
If lines are considered cylinders, they would have a radius of zero and cannot touch without intersecting.

Whoa, whoa, whoa! I still have a working CueCat. I think the Jury is way still out on this. I'm betting it will do better than the CueCat because Amazon as a company has a better track record, but assuming this was a brilliant move to use a proprietary, non-smart phone device is—it is just way too early!

For years my Slashdot signature has been :

There are places where the networks are not touching, and there are places where they are - Boeing's Lori Gunter

Which was the PR response when the FAA found out :

BOEING'S new 787 Dreamliner is at the centre of a security storm after the US Federal Aviation Administration revealed the jet's onboard computer network could be hacked by passengers.
The hacking scare was highlighted in a report conducted by the FAA, who said the plane's computer system, designed to give passengers in-flight internet access, is also connected to the plane's control, navigation and communication systems.

According to wired.com, the FAA said "the proposed data-network design and integration may result in security vulnerabilities from intentional or unintentional corruption of data and systems critical to the safety and maintenance of the airplane."

The FAA is now demanding Boeing address the computer-network issue before the planes begin service in November.

Boeing spokeswoman Lori Gunter said the wording of the FAA document is misleading, and the plane's networks "don't completely connect".

"There are places where the networks are not touching, and there are places where they are," Boeing spokeswoman Lori Gunter told wired.com.

Gunter also told the website that protections are in place to ensure that the passenger internet service "doesn't access the maintenance data or the navigation system under any circumstance."

Boeing are said to have received more than 800 advance orders of the 787 Dreamliner, which is currently in the final stages of production.

Speaking of the security concern, Gunter told the website that Boeing has been working on the issue with the FAA and "the problems will all be done before the first airplane is delivered."

Boeing will be hoping to have the 787 approved by the FAA before they take to the skies in November.

Actually, there is no reason for any of this. What app needs my contacts to function? None, so they are just stealing my contacts.

Repost of the comment I left on the Github issue:

This is going to be a bit of a drive-by comment because I don't have a great deal of time. Apologies in advance.

Firstly, I think you need to define the problem more precisely. I would define it thus: "the algorithm should return a list of sites ordered according to the likelihood of the user finding them engaging." Very quickly you need to decide if you are personalizing this list per-user or not. I'm assuming you're not.

With this definition we can go places because:
1. There is a huge literature on measuring engagement; and
2. There is a huge literature on generating rankings.

For the former we can start by looking here: http://www.dcs.gla.ac.uk/~mounia/ (There's lots more work in the field. I just happen to have some familiarity with her work.) For the latter searching for "submodular diversity ranking" will return a lot of papers with complicated algorithms. Yay!

The number one problem I see is that you don't have sufficient information to get a useful measurement of engagement. If you don't have useful feedback you can't learn if what you're suggesting is any good. At the minimum you want to measure clickthrough. Better would be time-on-page (possibly normalised by page length). Solve this problem, even poorly, and we can them look at using this to generate rankings.

As for generating rankings, while the submodular optimisation approach has some very nice properties (e.g. it maintains diversity in the suggestions) there are simpler methods to start with. Let's say we have some measure of engagement. We can put a confidence interval on this measure using standard maths. Then just display the sites that have the higher upper bound on the confidence interval. You should decay the measure over time, widening the confidence interval, to allow for changing interests.

Hope that's useful.

It has been known for a long time that one can arrange 7 cylinders to be mutually touching. That was written about by Martin Gardner decades ago, and was set as a puzzle.

The result had the cylinders touching at the end of one with the length of the other, so the question arose, can one arrange to have seven cylinders all mutually touching, without using the ends. The easiest way to say this is to ask for seven infinitely long cylinders mutually touching.

This has only recently been settled, hence this paper. It's believed impossible to arrange eight identical infinitely long cylinders to be mutually touching. I suspect the result is in fact known, but I haven't searched diligently for it.

There is an associated puzzle that uses cylinders that are very short - think coins. How many coins can you arrange to be mutually touching?

Consider that a puzzle. I can do 5. If you can do more, there's a mathematical paper in it for you, should you care.
"Preliminary data showed the rocket placed the spacecraft in an orbit with a high point of 12,807 miles, a low point of 176 miles and an inclination of 19.2 degrees."

Maybe I'm reading this wrong, but this appears to be a very elliptical orbit with a the difference between the high and the low being more than 70x.

Does someone here know what the purpose of such an orbit is? Obviously it states navigation but I guess that's not enough for me to understand why they would pick such an orbit.

There are free alternatives to Linux, such as FreeBSD and OpenBSD. Does anyone know whether their development is influenced as much by large companies as Linux is?
It's very easy to think that the other side of an issue does not hold a rational position. We use the same brain to hold hold our own opinion, and to evaluate the opinions of others. In situations outside the scientific method there is little way to objectively know which is the "right" or "rational" position.

The reason people get so crazy about this debate, at least, is that many see this as "land grabbing" done in a passive/aggressive manner by RH employees (merging udev and systemd under the same repo and having to build systemd to build udev is an example of that) and their pet project. Again.

People is bound to hate it. RH won't care anyway, they control the core of every modern linux system and can do what they please.

How are any ideas being suppressed?

Any more than boycotting Coors because of the anti-immigration policies of the Coors family suppresses ideas.

Any more than boycotting Disney because of its support for Gay Days suppresses ideas.

Any more than disinvestment of South African goods suppressed the idea of apartheid.

It comes across like you think every boycott is an attempt at suppressing an idea. If that's what you believe, then know that I stand with the oppressors.

Otherwise, is there any boycott you like which was done for social or political reasons and which didn't somehow "suppress ideas"?
That's certainly true for most Americans; in the United States, escargot is not a delicacy but a perennial joke. (I don't find it unpleasant, particularly, but I also don't really see the point; it strikes me as one of those things people eat, not for its own sake, but rather to be seen so doing.)
Surely mathematicians would use rationals[1] rather than floating point numbers, thus eliminating rounding errors at the expense of performance?

Whether they import a module or not is - IMO - irrelevant. I was responding to this claim: In Python, side-effects are simply not acceptable at all. One should instead put the code with the side-effect in a function and call it. `__future__` imports are obviously and purposefully side-effectful, there's no `print_function()`.

You (Americans) should treasure the existence of the minimum wage. One of the black spots on our otherwise rather generous social framework here in Germany is that there exists no minimum wage.

I don't know if the lack of a minimum wage has contributed to the failure of Walmart here, but they did sell all their stores because they weren't competitive.

Working at a Walmart probably pays better than many of the jobs at ultra-cheap supermarkets in Germany (Lidl, Real). I'm not saying that it pays enough, but at least you all can take some pride in the fact that a minimum wage is in place.

Good question! The impression I have is that we all, vegans included, draw a line somewhere, and that there's almost never any solid reasoning behind anyone's decision on how to circumscribe his diet. I'd be really interested to hear an avowed vegan explain why it's not okay to kill and eat animals which are capable of nociception, but okay to kill and eat plants which are also so capable.

Except they would be wrong. In cities, cycling is almost always provably faster than driving or public transport because traffic becomes a non-issue and you can start immediately when a light turns green instead of waiting for the 5 vehicles in front of you to start moving or turning out of your way.

I find this hilarious because before I can go further into hacking into fancy cutting edge deep learning models, I have to process years and years of XML data from an external party.

As someone else said, the only purpose of University is to teach how to learn. Everything else is up to you. Again, there are places that teach you specific skills that are job relevant now (Codeacademy/Bootcamps). You could very well do them and get a high paying job too.

However.

Figure out what you want to eventually be in life. Do you want to be a high paid janitor who can be easily replaced? Or do you want be the guy who can see through all the bullshit frameworks and design solutions that are robust. The guy who remains relevant at 40.
This is going to sound like trolling, but it's not - I'm honestly curious.

Why is this important? Is it just cool, or is there some real world application? Was someone paying for this research for some reason, or was it just a mathematician's hobby?

Again, if gay people are not more likely to act in a stereotypically gay manner, and you've said that they're not, then there is no reason to believe that gays are more likely than their straight peers to be abused for behaving in ways that are perceived as gay.

Dear leader? Oh you're one of them. Figures.

Those Crazy Americans: a boy's point of view
My main dilemma in school: I loved the humanities, but I also wanted something a little more practical. For this very reason I majored in Cognitive Science at UCLA (with a focus on AI). I was required to take the CS courses and I also was given a chance to take courses under the realm of bio, philosophy, psychology, etc. I think education should require a balance. A well rounded individual doesn't necessarily make the best programmer, but does make the best member of society.
