#6: Get an Android phone and do it in any combination of those ways or a million other ways.

In my opinion, one of Android's best features for years has been its extremely open "Share" button that developers can hook into for nearly anything, and all over the OS.
"Idle time" would be a better word.

Looking for Affordable Dental Insurance? Don't Make These Mistakes
Buying affordable dental insurance isn't difficult. After all, there is a ton of competition out there, so insurance companies are always looking for ways to draw in customers.
Interpreting various equations from my limited knowledge of such a discussed area, I've come up with this:

Hawking radiation makes a black hole lose mass, hence diminishing its Schwarzchild radius. The Schwarzchild radius came up because it's a singularity (in the mathematical sense) in a solution to Einstein filed equations. The same way matter collapses onto itself up to creating such a singularity and being encompassed into the now existing event horizon, as soon as there is not enough mass to sustain the singularity, the event horizon vanishes, hence the remaining matter "pops" back into our sight.

You could view it otherwise with a thought experiment: take particles out of the black hole one by one. Each time it will reduce the mass and maybe the radius. At some point the mass/radius ratio may not be small enough to hold light and the bubble bursts in plain sight as the event horizon breaks down. In such a thought experiment, the worst case would be that the black hole would require every single particle but one to evaporate (unless you assume a single particle could be a black hole in itself).

An interesting back of the envelope calculation is computing the mass contained in a Schwartzchild radius of Planck length (the size at which quantum effects take over).

l_P = sqrt(hG/c^3)
r_s = 2Gm/c^2

hence m = sqrt(hc/4G) = 1.0882546265651108e-08 kg which is a bit more than 1e22 electrons sitting at a position 1e-15 smaller than a single one of them.
This is a burden
I agree, and I believe it would be equally true if applied to video games. You don't become violent by reading crime novels or by playing violent games, but it could potentially change some of your general attitudes and your view of society.
Sorry -- I assumed too much knowledge. Cloud Foundry is really not at the point where it can replace Heroku. Its 80% of the way there, but every needs a different part of the last few % so you can expect to have to add to it based on what you need.
How to launch a side project that makes money from the first day on
"And if we're in a black hole, what evidence, if any, do we have for the effects of evaporation?"

Unexplained weight loss? ;-)

I am still wondering how to square the idea that we are in a black hole with the basic principle that aside from the law of conservation of matter and energy.
Robot Ethics: The Ethical and Social Implications of Robotics
I shudder at the thought of having to generate and store a crypto key for the lifetime of a machine in order to run it. This is why, btw, I've abandoned full-disk encryption: I once lost a key (in shambolic fashion), hence losing an entire disk.

A one-machine-one-key scheme is impractical for so many reasons, one of them being exactly that: onus is on the user to keep the key available but secret. People who blindly double-click on random .exe attachments would supply the key pronto as soon as any malware would ask for it. As all sysadmins know, securing a machine from its owner is often the right thing to do, and in that sense UEFI is not a bad thing.

Besides, if UEFI really becomes a staple of the Windows world, I can see enterprise/sme customers requiring a sanctioned way to add custom cert authorities, to which Microsoft won't be able to say no. Because taiwanese manufacturers like to reuse parts wherever possible, the feature will trickle down to the consumer market.

The more I read about UEFI, the more the scaremongering seems like paranoia.
>My point is, that one of the -other- benefits of having a breadth of
knowledge, is that it helps prevent unintentional derivativeness and mimicry.

I could not disagree more on the last part. Derivation and mimicry are the very
foundation of creativity. Good artists copy. They take from whatever inspires
them. In fact, there is no art that doesn't copy - you will not find art that
exists in the void. Everyone stands on the shoulders of giants. And that's a
good thing.
Is Anyone Spying on Your Cell Phone?
Nowadays, anyone who has an access to your cell phone can easily install a spyware software and monitor your calls, SMS messages, emails, browser history and even your location. Some advanced spywares can turn on your microphone and capture the phones surrounding sounds, as well as downloading the photos in from your phone gallery.
I don't know, I thought IV aside from their research division, is a company of lawyers that manage their patent portfolio.
What is that list ranked by? None of the columns are in any strict ascending/descending order. In particular Apple has the highest market capitalisation out of all the firms of that list, 540+b compared to Exxon (#1)'s 400b.
I hesitantly vote this up, not because I'm buying it, but because I love the topic, and would love to see HN talk about the concept of colonizing Mars. My understanding is that the biggest problem with terraforming it is the lack of magnetif field and the low gravity, yeah?

To be honest, I'd find it more interesting if it were a single, large, transparent container landed on Marsian soil, and then the inside was made (through means of repeatable large scale activity, not just pumping in air,) it was made into a green house. Then put a live web feed up.

A single room showing the potential of life on Mars is, to me, far more inspiring than people living in pods and having to use space suits to walk around.
Doesn't the new Facebook photos app do a lot of what this guy wants?
Don't get me wrong but what you describe looks like unplanned slogging in a blind direction hoping for a miracle to happen. This is what makes hard work look so inglorious.

I always liked the advice what Stephen Covey gives in '7 habits of highly effective people'. Begin with the end in mind , You must first plan where you wish to be in the next 3 years. Then divide what is would take to get there. Find out what you need to do at the end of every year. Then every 6 months, then every month, then weekly, then a day.

Blindly throwing your work for 3 years pushing 16 hour schedules and hoping things to work is like attempting brute force solutions towards complex computational problems. Its doing a lot of work for nothing.

If you plan, schedule, track and readjust course properly. Then you can be productive with a busy schedule. Yes resting is very important. Sometime no matter how urgent the task on hand is, I just slam my Laptop's lid and sleep. But other wise, I drill through my task list like there is no tomorrow.

We must learn to run a marathon in durations of sprints and periods of rest.
Ah sure - I see your point. Yes on the whole it was a bit of emotional hysteria driving reaction to this particular product when the same point could be made regarding all commercial meat production.

I suppose it became the perfect poster child to represent the general issue some groups have with modern food production in general (which I'm partly sympathetic to) but I'd agree that making false claims about food safety helps nobody.

"But a company like Google has the resources to fight dubious patents. When the average patent case is costing $5 million and up, the real cost is to the small companies, the startups."
Good point - they explain it here:

NB I'm not particularly attached to the Global 2000 - just it would be interesting to use a list that isn't only US companies.
$30 per month is not "exclusively for the rich", is it? Not in the Western world at least.)
I don't think it's intended as a portability test, but rather an implementation-defined vs undefined behavior test. And in practice it's safe to make assumptions about implementation-defined behavior as long as you're programming for general-purpose computers.

Regehr clarifies this in the comments section: "Regarding signed overflow being defined or not, compiler developers generally draw a sharp distinction between undefined behavior and implementation-defined behavior. 32-bit ints, 2's complement, etc. are examples of the latter and signed overflow is an example of the former. A lot of developers do not draw such a sharp distinction, which is why I made a point of asking questions about this issue."
No, because as an inanimate object it has no capacity for suffering or self-awareness.
Black holes and dark matter are likely to be just artificial constructs to rescue certain mistaken orthodoxies of astro physics.

Electrostatic force is much much stronger than gravity. It is known to be ubiquitous both on micro (sub-atomic) scale and on macro (cosmic) scale.

Once you acknowledge its existence, it is no longer necessary to postulate black holes in the centres of galaxies to hold them together.
Looks clean. Can you add title/description of the video being played?
So, I'm just a guy who makes video games. A one man operation. I'm mostly interested in interface and game design, I don't know, and don't really want to know anything about running the back end. Just the minimum to get the game running.

Right now I'm running my games on Google App Engine and hosting is about 10% of gross. (Don't know if that's good but it's fine by me). For me, scaling means going from 3 or 4 instances to 20 or 30 in busy times. This all "just works" and I don't have to really do anything.

I've been looking at Heroku because I've been working a little in node and there are some significant advantages to having js on the client and server. (rather than python on GAE)

I was under the impression Heroku would just work too. I may not be an Idiot, but I sure am a n00b.

Is Heroku not for me? Should I stick with App Engine?
I think the expression "just unix" is right - at the end of the day platforms like Heroku, CloudFoundry and dotCloud (since we're all plugging our respective platforms) expose an API to spawn and manage unix processes - the way EC2 exposes an API to spawn and manage servers.

It all boils down to the metaphor, and the language that supports it:

PaaS borrows from the Unix metaphor of deployment with primitives like processes, executables, virtual filesystems, sockets and stdout/stderr.

IaaS borrows from the hardware metaphor of deployment with primitives like images, block devices, OS installs, firewalling rules and load-balancers.

The premise of PaaS is that, in a large and growing number of cases, as a developer the Unix metaphor requires less of my time, it maps my day-to-day experience better (As fdr pointed out, the remote platform behaves the same, roughly, as my laptop), and I don't actually need control over the underlying hardware.

Doesn't this method also (over) simplify? It goes into pseudo explorer mode anytime there is a >0 probability that the presumed worst cast is actually better than the presumed best/better case. Shouldn't there be a threshold to that process, so that the presumed worst case must have at least a (for example) .05 probability of being better before the algorithm gives it a shot?
Q:
Why not just reuse the hash from Youtube like this:

I'm about to find out if this is true because I'm kicking off a "work out every morning" routine as we go through YC. I figure when I first wake up is the best time to sneak in something that I don't need all the gray matter for anyway and that will serve double duty by kicking the noodle awake more than a cup of coffee would.
If you use that much Red Bull, you got 2 issues (at least): the sugar gives a rush, but the bloodsugar level will plunge. And each time you continue it plunges even harder and faster.

Second, Red Bull or any caffinated beverage will attack your adrenal gland badly. Realy hard. Your adrenal gland is responsible for your adrenaline (duh) and gets triggered by the caffeine. So, it's not the caffeine that gives you a boost, but the adrenaline that gets released. Until it's gone, drought up, vanished. You can drink Red Bull till you die, but the adrenaline won't be there. Until you fix it.

You see, your body is a bank. A bank full of nutrient to be released when some other part of the body needs it. If you never make deposits, you won't get any interest either. If you only make withdrawals, you will end up with debit. If you continue you go bankrupt and die.

Healthy hackathons? I guess it's possible. I eat a lot of butter from grass-fed cows. I use omega-3 a lot and magnesium. My brains work much better and that without any caffeine. There are other supplements one can use, but always with moderation and enough sleep. Without sleep, your hormones won't get any rest or balance.

Hackers who think they have super powers and don't need sleep are having a Wall-Street mentality prior to 2008. Grow up, you only have one body, so you better take care of it.
The more affluent area will be paying much more council tax, the rates are calculated on property prices. It's the same "pool" of tax, sure, but it's in no way the "same tax".
I planted two plants at two corners of my home here in Bangalore, around 10 years back. Today they are large trees, I don't live in a area that you can describe as only where rich people stay. But you don't need to be rich to plant a tree and watch it grow. Its not like maintaining a garden. You don't have to spend a dime. And most trees don't require much maintenance(That is how they grow in the forest). So its not a rich man's thing by any measure.

Apart from the season of Autumn, where you need to broom out the leaves the tree has no other need to tending to. But the benefits are enormous. I go on the top of my home during the nights and its always cool in all seasons. There is always shade, early in the morning birds chirp and its very pleasant to hear that.

My home looks like an Oasis in the middle of an desert as there no trees around. Kids play under it, People like to stop for quick rest. Even from far things look green and fine.

Its only an excuse that rich people stray around green places. The fact is anybody can plant a tree. It doesn't take money to do it.

An absolute monarchy with near absolute control over the main (and large) source of income.

This is something you need to really take a second to let sink in. The King (or prince) can decree, fund and away it goes. Billion dollar universities, palm shaped islands, pyramids. Just to put it into perspective, the current King took over the country when his Dad was overseas in the 90s.

Doesn't everything reconfigure our neurons? Isn't that the essence of conscious experience? To claim otherwise implies dualism as far as I can see.

We know that the dynamic electrical state can't have much to do with it, because you can cool the brain to the point where all electrical activity ceases and it doesn't have any significant effect when you wake them up. That only leaves the configuration of the brain's parts.

I suppose that there is so much of the biology we don't understand that we can't make strong claims at all, what with microtubules and the like.
I tend to agree with the "logical business decision", but what this means (I'm just speculating really), is that when a business reaches profitability, or taps a growth market, then the potential profit vs legal costs will turn on. Which means that IV and Big Name companies can strong arm the up-start company to either join their patent trolling or turn over some percentage. For what amounts to flimsy and obvious software ideas/patents.

Unit Testing a Window Manager
> Wouldn't anybody understand it in its intended meaning (synthetic)

My point was that there isn't necessarily any difference between "synthetic" and natural.

This organic vs. synthetic is largely a media/propaganda driven misconception. What is important is caring for the plants and animals, and not abusing pesticides, fertilizers and medication.

It's the same thing in herbal medicine and health food. Just because a product comes from a plant it isn't necessarily good for you or risk free.

Aside from that, I feel "chemicals" in farming more often refer to fertilizers than pesticides, here in Sweden.
An Arab friend once told; all those pseudo-oil-kingdoms-with-small-populations (from Brunei till Qatar) are created by colonial powers of 20th century around the oil fields to save the oil revenues from a larger population benefiting and controlling them. Those sultanates usually play the happy-sultan-cherishes-its-people-wow! game recently. But if you look around them, they are cut-off from poorer countries with larger populations.

I am skeptical of those oasis of happiness in the middle of a desert full of desperadoes.
Documenting jQuery plugins jsdoc-toolkit

This can probably be said for nearly all "journalism" in the US.
> Even dragging out the USB cord to plug my phone into my MacBook Pro doesn’t yield a simple solution. Open iTunes, iPhoto, etc. – haven’t found the answer.

There's an app called Image Capture, installed on every Mac, that lets you easily download certain photos and videos from your iPhone (or any other camera). It simply presents a list of media on your device, which you can save in any location you want. There's no organizational aspect, unlike iPhoto. Image Capture doesn't help with the uploading/sharing part, of course, but it's much more streamlined way of directly downloading photos versus iPhoto.

Yeah, some people have non-FB-using family members or privacy concerns. For most people, however, this is where sharing is headed IMO.

The author seems to want "his cake and eat it too ... for free". I'm not sure where you'll get cheap/free storage that (a) keeps up with megapixel growth, (b) is easy to use, (c) uploads fast in the background with no waiting, (d) doesn't require the recipient to sign-up for anything, and (e) is run by a benevolent CEO who cares about your privacy more than his/her startup's growth.
Heroku virtualizes dynos with linux container (lxc) [1]. The good thing is that lxc is very lightweight because it shares the host's kernel, so dynos aren't slowed by another virtualization abstraction in addition to ec2 xen. The bad thing for heroku users is that memory does not need to provisioned upfront for dynos, so spikes in memory usage of neighboring dynos can eat up all the memory in a physical machine.

Yes. I think owning versus renting/tenanting/being housed may have a lot to do with this. Why go the the effort of planting trees and spending your time on your landlords garden.
Trees are healthy for human psychology. I'm glad cities are planting them.

Strange, though, how different perspectives can change perceptions. The photograph in the article is said to depict a wealthy city with a large number of trees, but just looking at the way all those cars are parked in the road, slowing traffic and posing a constant threat of a crash resulting from a moment's distraction makes me feel claustrophobic.
