you're just pointing out a minor difference in my analogy. in cancer, the "population" is the tumor cells in a single human's body, while with bacteria, the "population" includes invading cells that infect multiple people and carry resistance between them. In both cases, the dividing cells propagate their inherited traits that allow them to evade the immune system or treatment.

When you treat a person with a cancer drug, the cancer tumor population evolves (selection and natural variation), when you treat a population with an antibiotic, the bacterial population evolves. That was the point of my analogy.
How to sell an open source Android game?
A while ago, I wrote a simple strategy game based on Reversi, but with a few key differences in the rules. I showed it to some of my friends, who really enjoyed it, so I wrote an open source Android version called Chain Reversi over the summer, and published it on the Android app store (https://play.google.com/store/apps/details?id=uk.co.techmeology.chainreversi&hl=en). I had hoped to earn some money from it, but so far I haven't managed to get anyone other than my friends interested in buying it since my skills are mainly in technology rather than marketing. I decided to make the game open source because I figured that might get a few people (who care about stuff like that) interested who might then share it with their friends and get some exposure for my game, but that hasn't happened. How have my fellow Shashdotters gotten their success in selling on the Android app store?
I'm sure the last few times people built reactors for fun, people with large guns appeared to ask them to stop what they were doing.

Poll: Watching "The Hobbit" - IMAX, HFR or 3D?
Hi,

"The Hobbit - The Desolation of Smaug" is nearly available. Which method would you recommend for the "best" experience?
IMAX
HFR
X for Y is just a simple way of explaining something. Smart people can maybe make two leaps, but most people have trouble making a mental leap that's further than one step away from what they know. So you start with "X for Y" as a mental hook to hang their mental hat on. Then you can build from there.

Whether it's actually an original idea or not depends on nuances of the space, that most people aren't use to talking about, unless they usually think of this sort of thing. So it's easy to be dismissive.
Its called the Jacobian. The differential of the outputs by the inputs. Tells you how each input affects the output vector at a specific location in input space. You can calculate it manually. Use inbuilt Matlab functions or finite difference it.
Aw, I was hoping it would autodetect faces and apply the hats accordingly.
I think we radically underestimate the sheer volume of technology that predates 1500 Europe. (Roughly where we count the modern western world from.maybe)

From the Antikythera mechanism to Hero's steam engines, model planes in Mexico and ball bearings on Roman emperors ships, humans did not lack invention, but what bound the modern world together was not better inventors but cheap printing and wider distribution of those ideas so they would not die out when one location failed.

I suspect that civilisations occur when they make the retention and spread of ideas pass a critical mass (ie the empire provides sufficient protection that an idea created in one place can find a home elsewhere in the empire (comms network)
> Just a few days ago my debit card was blocked

If this is all there is to it, I'm not sure I see the utility. I travel internationally somewhat often, not only has my credit card never been blocked, I also usually carry some amount of cash in the local currency so I wouldn't be screwed even if it were.

Transferring money internationally is a bit of pain, you're right about this. But it's also a regulatory minefield. I simply don't want to risk - (a) the IRS coming after me and (b) all the problems associated with bitcoin purchase and sale - just because I'm trying to save a few bucks in transfer charges.

This is the most interesting part of your comment.

> I usually have two options to get paid by advertisers. Paypal or Bank Wire. Paypal charges huge fees, so I opt for wire.

Now, paypal are enormously profitable and they don't give a shit about small businesses which is probably why you end up getting screwed. Maybe bitcoin can help you there, but it's probably better if you could get dollars instead of bitcoin through a bitcoin like protocol. I think it's important to distinguish between the bitcoin protocol and the currency itself. I think the former has some good ideas which will almost surely make in to many many other protocols and applications. The latter, I suspect, is best avoided by "normal" people.
WELL, if we're talking about INTENTIONALITY then yes the american medical bureaucratic system as evolved obviously singles out the uninsured and proceeds to screw them over.

If we're talking about mens rea, then I doubt it; my wager is tied to how it's in no one's incentive to care that leads to these outcomes. Medical providers are clueless and totally disconnected from administrative functions, hospital billing systems are optimized towards dealing with horrible leviathans that spew sulphur and vomit acid and all of this operates on a scale that makes makes the cost of delivering babies a rounding error.

I'd imagine someone forgot to properly code the procedures/the paperwork isn't set up to give a shit and they were simply charged the default set of procedures.

Blah blah, single payer public systems, blah blah aligning incentives around cost structures, etc. Atul Gawande has a great few articles on this.

It actually does, depending on your reactor design.
I went a few months forcing myself to get up early. Though I got used to it being up at 6 and working by 7, I couldn't ignore the blanket of grogginess I felt all day..
If this article is news for you, this might be a helpful corollary:

Threads and processes are both units of execution. (A unit of execution is like a virtual processor -- a separate instruction pointer that makes its way through your code, doing computations and following jumps.)

Both threads and processes have their own stacks. You reserve a new stack when you fork(), or when you spawn a thread.

But only processes have their own heaps. In fact, this is the defining distinction between threads and processes: if you're sharing your heap with other execution-units, you're a thread; if you have your own isolated heap, you're a separate process.
To be honest, there is a need for something much more filtered than bitcointalk.org. That used to be /r/bitcoin, but it really sucks now.

My question for the coinspotting people: How are you going to maintain high quality? If you don't have any plan, it will probably be filled with crap and eventually die.
Ok, can we stop now? They reason I prefer HN instead of say Reddit is precisely because all the news are in one place. The new trend "Hacker News for X" basically means hey guys let's make Reddit, without all the good stuff.
Skate where the puck is going to be. How much confidence can you have nowadays that your job isn't one clever-roboticist away from being automated, if your main value contribution is skilled labor? The same economics that drive high pay for skilled welders who work in the heat also will drive dollars towards automating these jobs. If I have to pay a welder 100k a year now, if I can automate their job away for anything less than that then it's worth it.

The truth is college is a form of leverage. If you get a solid degree you have basically added a skills multiplier to many things you will encounter in your career. The same cannot really be said if you become a master tradesman, since the deeper you go the less transferrable your skills become.
9 times out of 10 interruptions that I remember had nothing to do with improving others productivity but getting around what can best be thought if as systemic pathologies - meetings to convince people who should have no power over the project the project was on track, discussing schedules and projections. Rarely were the right people involved.

So be glad your interruptions have a net value. Maybe my anecdata is untypical - It would be nice to think so.
Yea, I suggested that B&N should have brought it up with the DOJ when they got the chance.

Mini reactors are becoming a big industry.

For cities or countries (or large ships) that can't afford a full-scale nuclear reactor there are smaller and cheaper ones that can replace fossil-fuel power plants.

I'm sure most people go into the nuclear field to experiment, few people expect to sit around with a checklist and watch a dial.

This company is working on similar goals: http://terrapower.com/
Viruses are only one potential cause of cancer, and there are several known tumorigenic viruses (HPV, adenovirus, EBV, polyomavirus, etc.). There are still researchers that believe that all remaining cancers are caused by yet undiscovered viruses (the "viral hypothesis"), but these researchers are becoming scarce.

It seems more likely that cancer can also be a disease of aging and degeneration. As we get older, things break. Cellular division is liable to be one of those things. There are identified mutations that dramatically predispose people to cancer, because one of the genes controlling cellular division is already broken (the "Knudson hypothesis").

Some researchers do prefer to use the viral cancers as a model for studying the others, because they luckily have a singularly identifiable cause, and therefore seem more likely to point to the causative mutations behind cancer as a general process. This is the premise for a paper that I helped author: http://www.nature.com/nature/journal/v487/n7408/full/nature1...

Nitpick: in the same vein, not all gastric ulcers are caused by H. pylori. Another common cause is chronic NSAID (e.g. ibuprofen) use.
It is complex as soon as you try to do anything but simplest things with Neural network. What I really liked about Coursera's NN class is theory of how RBM's can be used to model associative memory.

If I had a degree I could get a TN1 VISA, in 6 months I'll have enough work exp to qualify anyway (12 years). I could get an H1B but it seems like too much hassle.

The UK will apparently accept me, I have to say there's a world of difference between UK and US immigration, anytime I've dealt with US immigration I felt like wanting to do anything another than vacation in the US was criminal. In the UK however they seemed A OK as long as I had a return flight, they were even friendly.

Although it didn't pan out as I was extremely jet lagged, sleep deprived and bombed the interview I'd highly recommend talking to Facebook, their people were super accommodating and really went the extra mile to get talent on board. They basically figured out all my VISA options worldwide for me.

"Good Thing" is often capitalized, or as above italicized, for emphasis in hacker circles. The idea is that it's established jargon [1] suggesting more specific meaning than a casual goodness remark (whether that's true or not, I'll let you decide). The TM is another such intensifier, with the informal meaning of "distinctive or characteristic", rather than literally trade-marked.

> "If you have an underlying neoplasm (tumor) like these patients had, then the risk outweighs the benefit," he said. "However, if you are doing well on ARVs and you merely want to get off antiretroviral therapy, then the risk seems greater than the benefit."

Is this a typo or am I misreading it?
What's the name of the software you use to track your hours and productivity?
That is one of the emotions.

If you read the article you will read about two reactors that are actually fueled by what we consider waste today.

That we don't completely burn the fuel used in a reactor is a 'bug', a misfeature if you will. That was expedient when the initial reactors were being brought online and now is a regulatory pain in the butt. There is nothing in the physics that requires a nuclear reactor complex to generate nuclear waste of any kind[1]. Only in the regulations.

[1] Nuclear incineration of even low level waste can effectively convert anything that was once radioactive into short lived nucleotide. Converting everything burned into its lowest energy stable state. But we don't do that either.
I actually see it as a sort of competition. There's a problem, namely, people overeating due to emotional distress. So let's have a race and see who can solve it better. The psychologist will say "go to therapy", the doctor will say "exercise more", the priest will say "try volunteering" and the engineer will say "here's an app for that".

If it turns out that the engineer's solution works better, well, a) it's up to the rest to come up with a better solution, and b) I can't blame the engineer for coming up with an engineering solution. I actually find it refreshing that they are working on that instead of Adwords/Zynga/NSA stuff.

And of course, this bra/bracelet thingy doesn't rule out the alternatives. If you don't like the engineering approach, feel free to try anything else on the list.

While I do speculate that Microsoft has more vague patents that it's using to sap Android OEMs, I do think this was one of the more prominent patents, as Microsoft itself went on the offense with it (IIRC it tried to get Motorola phones banned for violating it).

It made my day to see that a comment by Linus Torvalds himself made this patent end up in the garbage bin of IP harassments.
It becomes a lot easier to think about these circuits if you realize that many of the connections are actually spurious. That is, if you remove them and systematically test the function over a range you'll realize that many of these weights have no information bearing value. For instance, if you have a w_i_j=0.01 this may be totally insignificant for any sigmoidal function and for all intents and purposes should be w_i_j=0 in which case this complex web of neural connections is trimmed, resulting in the underlying circuitry.

If you're interested I wrote a paper in Nature Systems Biology that shows this for artificial gene networks (just another branch of ANNs): Survival of the Sparsest: Robust Gene Networks are Parsimonious
I'm not so sure. A lot depends on how many there are, and how often they get funded, because they will destroy a lot of wealth and provide bad experience for the people they employ along the way. There seems to be more potential for harm than for wannabe pop-stars.
Why an extension?
Oh yes.

Heaps for allocating textures. Object-type-specific heaps for things like sounds and models. "Smart" heaps that can invalidate their contents under memory pressure (and maybe automatically bring stuff back in, possibly speculatively). Heaps that are good for lots of small allocations. Heaps that either do or do not allow multiple threads to use them. Heaps that are position-independent and that can be used in shared memory buffers (which can be mapped to different addresses in different processes). I could go on.

I wrote a lot of the memory management stuff for the Apple Newton, and it had several types of heaps:

- A common "Macintosh-like" heap with both fixed and sliding blocks (even with a VM system managing the page for you, fragmentation matters when memory is tight). Most threads played in this heap, and keeping it sane was kind of hard.

- A couple of heaps for the kernel, for managing its objects (it's been a while, I don't remember why there was more than one).

- A heap that could supply (limited) amounts of memory for interrupt handlers.

- The NewtonScript object heap (owned by the NewtonScript environment).

I'm pretty sure there were a couple more heaps, but I've forgotten the details. Our main worry was fragmentation, and I'd say that things probably weren't segmented enough and that we needed even more heaps than we shipped with.

A heap is just a data structure. Ain't nothing magic.

Why don't you try getting an internship? Don't mention to companies that you've dropped out, just say you're taking a break to focus on personal development or something. After the internship, you should be able to get a job. I don't recommend doing a bootcamp if it will significantly deplete your cash. If you have around 6 months of expenses saved up + the fees for the course, then go for it! App Academy does not have an up-front charge as well, so it sounds perfect for your situation.
just a few facts: Canada has more public debt than the US by percentage of GDP:http://en.wikipedia.org/wiki/List_of_countries_by_public_deb... And Canada has a lower GDP growth rate. Unemployment rate is about the same (6.9% vs 7.0%)

US inflation rates are very low right now (~1% for 2013): http://www.usinflationcalculator.com/inflation/current-infla...

The CLR has at least two that I'm aware of, the "regular" heap (not sure if it has a special name) and the Large Object Heap. Pretty sure there are unmanaged heaps associated with a single .NET process as well -- certainly there are if you are mucking around with things like managed C++.

Interesting, by looking up mapcan, I came across the Simplified Lisp Reference:

Also linked from the resources-section of:

I don't think I've come across the simplified reference before -- appears to be a good resource for those of us starting out with lisp -- striking a balance between all of CLOS and the sometimes simplistic presentation of text books.
Yeah, maybe, but Chaos Group seem to be fighting back a bit with Vray 3 (much faster MC GI and BDPT support)... - they still need to sort their GPU side of things out though...

It's great that there's so much competition and so many renderers out there at the moment. This is partly due to the fact that it's not that difficult to write a "close to production" raytracer (ignoring asset paging, recursive procedural and curve support, which is where the big boys really shine).

They might be at historic lows, but crime rates in the US, particularly gun-related crime, remains absurdly high when compared with the rest of the world. You can compare the gun deaths in the US with the gun deaths in 12 or 13 other countries whose populations sum to be approximately that of the US and note that the gun deaths in those countries are significantly lower.
