A python implementation of is_prime(n):

  return re.compile(r'^1?$|^(11+)\1+$').match('1' * n) is None


For me, weight lifting improves my sleep far more than cardio.


I have the same experience, provided it's early in the day. However, swimming a couple of km does it for me too, maybe even better!


When I work out in the morning I sleep like a rock and can fall asleep as early in the evening as I would like.

When I work out at night I usually feel energized afterwards and tend to stay up later.


Just an interesting observation: People with known mental health conditions are twice as likely to poison themselves in a suicide than those without known mental health conditions.


Firearms are more popular with men and poison is more popular with women. (edit: source https://en.wikipedia.org/wiki/Gender_differences_in_suicide#...) The charts in the article show that women who commit suicide are more likely to have a known mental health condition than men, so that could explain the correlation.



Well I had fun with it http://i.imgur.com/EaQBYHX.png


Not super related but I cant resist. The guy in the article looks almost EXACTLY like Steve Jobs.


Yea, glad I'm not the only one thought saw that. Maybe they used the wrong stock image? :-P


Standard urban/casual intellectual uniform.


Only in the United States.


Part of me thinks it was purposeful


It says T-shirt OR Mug (x5) so I'm assuming you can choose any combination such as 3 shirts and 2 mugs.


Raising money will, without a doubt, make your lives more busy.

I've never heard of anyone successfully using investor money to hire people which replace them. Even so, hiring people is incredibly time consuming, and you will have to manage them.

If you're profitable and your goal is to reach financial independence, in this market I would not raise. If your goal is to make as much money as possible and lose all sense of work life balance, then raising money may be for you.


I'd rather google patent them than some other sue-happy company who will abuse them. Who knows, maybe they will open source the patent.


I felt similarly about Sun, but then Oracle bought them.


Hypothetical: in any alternative universe, would you have felt any better if Microsoft or IBM had sued a defenceless Sun into bankruptcy?


Google has the largest market cap so that isnt a concern here


Google has the largest market cap right now so that isnt a concern here yet

FTFY


Sun's market cap was once one of the largest.


I rather no company patent them than any do-no-evil company. Besides why do you think they won't use/abuse it? The whole point of spending so much ridiculous amount of money on a patent is to get exclusive rights to be the only one to use it. Isn't competition better than stagnation by a single company?


so, how do you ensure no company patent them?


Write the same documents but instead of submitting them to the patent office, release them on the Internet.


Demonstrate prior art? There are a lot of ways to do that without releasing production code.


Given historical prescedent, is existence of prior art actually an effective way in practice to prevent the granting of a patent?


Nope, but that doesn't matter - as enforcement is the concern, and there prior art shines. If the motive is purely defensive (and I don't include the menacing of a portfolio in that category), then it is the ideal move to make - as bad actors waste more energy filing poorly researched and easily refuted patents.


Probably doesn't prevent the granting of a patent, however it makes it impossible to enforce the patent. Mike and I published this in 1998 http://www.rage.net/wireless/wireless-howto.html . A Cisco legal team found this in 2008 and contacted me because the owners of patent #7035281 were coming after them. Doing a simple write-up of what I thought was obvious at the time - stick a wireless card into a Linux PC and have it route packets - may have saved all of us from having the wifi router in everyone's home restricted by patents. So whatever ideas you implement, be sure to blog about them and make sure archive.org gets a copy.


The problem is that other people will just create one or more patents which are around using your breakthrough algorithm in different contexts. The famous amazon one-click shopping patent as an example. The internet is the breakthrough, but because there's no patent on that, its easy to surround with patents that should be too obvious to be patents, but have legal teeth even so.

If you patent the core idea, the other patents become a lot less useful. (Not that I think Google is thinking this way. It's just a PR problem to them. When no one is looking, I bet they do whatever they can to get as much money/power as they can.)


It is a terrible situation, and putting out prior art certainly doesn't fix that - but the alternatives courses of action are worse (assuming purely defensive interests). I think you're right though, if the internet was somehow patented then we wouldn't have one-click shopping patents... or much of anything really - we'd likely be having this discussion over a Minitel service.


Consider the development of Microsoft's attitude regarding software patents. There's no reason whatsoever to think these patents are in good hands with Google, especially considering that their Android licensing policies seem to be carbon copies of old Microsoft tactics.

Their goal as it seems up to this point is to get a monopoly on the framework and technology with opensourcing of their framework. Good for hires and keeping the competition in check. A patent will tighten their grip on ai.
