Sounds like the only people making money off of bitcoin mining are the manufacturers of these increasingly more powerful ASIC mining hardware. Once one gets developed and released, it's only a matter of time until it costs more in electricity than it's mining. Then, lo and behold, they're ready with an even faster/more energy-efficient one.
Wow, I didn't realize it had food. Good call! :)

I interpreted that as '30 percent less than', closer to power pricing I'm used to in the US.

Notably Tiyo Triyanto, the miner quoted in the opening paragraphs, is now mining Litecoin instead of Bitcoin and betting on prices increasing before the ASIC arms race starts for that cryptocurrency.
> "the Iceman and those 19 share a common ancestor, who may have lived 10,000 to 12,000 years ago," Parson said.

For us hackers and compsci people who are used to thinking about the rates of growth and binary trees, it shouldn't be surprising that the most recent common ancestor of all humans has been estimated to have lived less than 10k years ago. Wikipedia has a nice article on it -- http://en.wikipedia.org/wiki/Most_recent_common_ancestor
This just makes me stop and think for a second how connected we really are. Blows my mind.
Patton Oswalt's Fake TED Talk Is Pure Nonsensical Inspiration
Exactly, the politics it causes invariably causes wages to rise. Always add 20% to whatever you are telling people.
this is something that is often misunderstood about pre-modern life expectancy. When life expectancy is calculated it includes infant mortality and child mortality, which historicly was extremely high. If you managed to live past about 10 or so in an ancient soceity your life expectancy was typically 70 or better.

A future is a simple blocking mechanism. The Scala example above uses something called a future, but isn't. It's an "Rx" functional future – cool and often useful, but it's yet another construct that isn't part of the actor model. I'm happy to use Rx, but I wouldn't use it in an actor.

There are many ways to tackle concurrency, but IMO it's best to keep them separate as much as possible, or you quickly lose track of what's happening when.

Unsprung mass
$114 a day is equivalent of $14.25 working 8 hrs/day. I think there are many ways to make $14/hr without investing in expensive equipment (which will also need to be replaced eventually running that hot). Actually, person that is capable of building such thing and keeping it working could probably easily fetch much more than $14/hr.

Right - this is the crucial point. The method suggested in the XKCD comic isn't to pick four words yourself out of your head - it's to randomly select four words from a dictionary.
Holy crapola - they are putting a Lua interpreter in the kernel, and it has access to some limited calls.

This is partly driven by "we need device drivers and no one understands C anymore", partly because it's cool, but mostly because Moores law is still alive and well. They are putting a scripting language in a kernel ! Forget write your app in python / perl / Ruby then optimise in C - the raw power argument is going to overwhelm us all.

I heard a stat the other day - that a greetings card, the kind that plays a silly tune, has more processing power than all computers on the planet in 1960. And we should expect a similar growth in the next 50 years. Even if that's out by two orders of magnitude just let it sink in.

I think we are at a Cambrian explosion period - where the goal is to try out every possible new body shape, as fast as possible and see which ones get the Darwin seal of approval.

New organisation forms are possible, some for the first time in human history, new ways of thinking and communicating - it's stuff like this that makes one realise the water around the frog is getting hotter.

Note my emphasis in this snippet of my comment: "Talking about how much you make, outside the workplace,..."

Discussing wages with your employers/colleagues has advantages, and without it collective bargaining is difficult to impossible. However coworkers account for a slight fraction of those that most people interact with.

There is no utility in me (someone who works in tech) telling my brother (who works in aerospace) how much I make, and vice versa.
Well, we know that bitcoin was developed by someone, and that they've managed to keep their identity(s) secret. The smaller the group, the easier it is to keep secrets. It's likely that if the NSA was behind it, or knows who is, then that would have come out in the Snowden leaks.
Ask HN: A weekend in Silicon Valley
I left my job in investment banking to start doing some freelance development and maybe start something up. As part of leaving I get to go to our USA office (in Detroit. I live and work in Sydney) and while I'm there I really want to visit Silicon Valley, most likely on the Oct 26th weekend.

As something that I read so much about, how can I get the most out of a weekend there? I'm most interested in just meeting like-minded people and hanging out, but unfortunately I don't know anyone living there.

Any tips? Cheers guys
To Do: Ignore All Those To-Do Lists
Yup. I was watching a video about the history of BSD recently and I was surprised at how closely DARPA was involved. Marshall McCusick was describing how he, Bill Joy and others were at Berkeley and literally implementing the Internet in BSD! They were funded by DARPA and were overseen by DARPA admnistrators. But they actually were not doing all of it -- DARPA was also paying private contractors for other components. (Which ended up in some technical disagreements as I recall.)

That BSD code is of course not only the foundation of the Internet, but of your iPhones and iPads as well. Actually I believe it is fundamental to Windows as well, since my understanding is that the TCP/IP implementation in Windows is BSD code.

Silicon Valley doesn't have the foresight for the technical foundations of society (and I say that having worked here for over a decade). The web wasn't invented by Silicon Valley either. Neither was e-mail. Neither was Perl, PHP, Python, or Ruby. Python was actually government funded too.

Also don't forget that Bill Clinton and the government made all your location-based apps possible, by opening GPS satellites to the public in the 90s.

Anticipatory Computing: The Next Big Thing Is Enabling Laziness
Ask HN: should my startup have a blog? if so which one?
getting my startup going, just wondering about the value of a blog.

obviously if we do it we'll try to make it good and keep it up to date (i.e. i realize there is no point making a blog with no posts). and i also realise that marketing the blog is a big part of it, not just making some posts, if there are any tips on marketing that would be great too!

i've also read conflicting arguments (mainly re:SEO) about doing it self hosted on a /blog vs. a tumblr blog, any thoughts?
They are very common for software and complete systems including serious amounts of custom software. Also partners on IDIQs, especially large multi-award ones, are very common. At least they are on the civilian side. About half my life is spent working on proposals in response to tasks for complete systems issued under multi-award IDIQs.
Yes, I'm American. I'm also generalizing and simplifying because an in-depth analysis of the China scam is the proper subject of a Ph.D. thesis and not a HN comment. As lionspaw has noted, there are complicating factors like the property boom (/bubble) and the grey market for inflation-resistant currencies. These hamper the current capital controls but do not render them entirely useless.

Of all the bike shops in Boston there is only one that I know of that sells wheels for older bikes. There are multiple widths between the dropouts and for the gear cluster for 5, 6, 7, etc. speed hubs. There are multiple rim diameters. There are multiple spoke patterns.

That alone makes it unlikely that, even if you are not alone, there aren't enough of you to matter when the FOB price of a basic e-bike is about $300.

Retrofit markets for anything less permanent than a house are very very tough.

They show about 20 cells. For cheap lithium ion batteries, that will be something like 150 to 200 watt hours. This is not a ridiculous figure relative to the stated range.
If it were that simple, people wouldn't be spending so much time configuring caches or using Redis. I think most non-trivial applications require some central, shared, data store. More often then not, this data store becomes a bottleneck that limits scaling. Databases compete with one another over which interferes with scaling the least.

If you accept the premise in the opening quote about Amdahl’s law, then you must consider that any global or semi-global lock has a huge impact on scalability. Sometimes we have no choice, but I believe that we can and should remove many single-points-of-synchronizations while still keeping the programming model relatively simple. I also believe that rather than hindering scalability, a database can help achieve it.

I think there's a step in between where we are now and making true anticipation work. For now, our next app is all about setting up routine timers w/ conditions. Over time, the conditions may evolve into something that seems more and more anticipatory, but I think user-set exceptions will always be necessary to make it viable.

Correlation does not imply causation
One of those stories floating around the 'net:

"In 1986, Peter Davies was on holiday in Kenya after graduating from Louisiana State University.

On a hike through the bush, he came across a young bull elephant standing with one leg raised in the air. The elephant seemed distressed, so Peter approached it very carefully. He got down on one knee, inspected the elephants foot, and found a large piece of wood deeply embedded in it. As carefully and as gently as he could, Peter worked the wood out with his knife, after which the elephant gingerly put down its foot.

The elephant turned to face the man and with a rather curious look on its face, stared at him for several tense moments. Peter stood frozen, thinking of nothing else but being trampled. Eventually the elephant trumpeted loudly, turned and walked away. Peter never forgot that elephant or the events of that day.

Twenty years later, Peter was walking through the Chicago Zoo with his teenaged son. As they approached the elephant enclosure, one of the creatures turned and walked over to near where Peter and his son Cameron were standing. The large bull elephant stared at Peter, lifted its front foot off the ground, then put it down. The elephant did that several times then trumpeted loudly, all the while staring at the man.

Remembering the encounter in 1986, Peter could not help wondering if this was the same elephant. Peter summoned up his courage, climbed over the railing and made his way into the enclosure. He walked right up to the elephant and stared back in wonder. The elephant trumpeted again, wrapped its trunk around one of Peter legs and slammed him against the railing, killing him instantly.

Probably wasn't the same fucking elephant."

You can, but communication between processes is usually more difficult than communication between threads. Sometimes you want to do more than pass messages. For example, you might want to do something as simple as increment a single counter. Sharing a counter efficiently among processes is not so easy.
Ask HN: Best websites for finding freelance jobs?
I have recently been interested in doing some freelance work to make some extra money (i do HTML5/Javascript/CSS, php, python, ruby, other web stuff). There seems to be an overwhelming amount of websites/services that help you find freelance developer jobs.

If you have experience in this realm, it would be much appreciated if you could lend me a hand and reply with some websites you suggest and/or have experience using. Thank you very much.
Technically, I was inspired by Rails for Zombies (http://railsforzombies.org) as I had been learning Rails for my new job, and had that fresh in my mind when my bosses said "come up with a new idea". For me, the inspiration was "how COOL would it have been if the interactive console in Rails for Zombies actually made the zombies do stuff and it was more like a game than learning to code!!" After some discussion, the choice was made to switch from zombies to robots because a) "programming" a robot made more sense than programming a zombie and b) robots seemed more "gender/age neutral" than zombies that have a more limited appeal. It wasn't until much later on that we started doing market analysis that we found LightBot. To me, LightBot was a confirmation that there was a market for "games that use programming as a tool", but not something that we were necessarily going to mirror. LightBot is fun, but ramps up quickly and gets pretty in depth into programming concepts pretty quickly. I wanted BotLogic to be a more subtle introduction where the user didn't even realize they were learning how to program along the way. I also wanted players to get comfortable with the idea of "syntax" and "typing code", and I feel the terminal is an important part of the game that LightBot doesn't have (not that it's a bad thing for their game, just that it's definitely something vastly different than going with a purely visual UI).
There are color management solutions for Windows and Linux as well -- the important part is that you calibrate your display (or other output device) to create an ICC profile, and that there's a way to install the ICC profile. (Example: http://www.lightroomforums.net/showthread.php?14070)

It's true that ICC profiles don't get you much if everyone involved doesn't have a calibrated display. And many users don't. That said, it's still valuable as a baseline and when working with other designers.
I'm looking forward to this hackathon. Way to raise the bar, Jason!

I feel you'll have to be careful around folks bringing in products they've already been working on and trying to pass them off as weekend hacks. But I'm sure you and the other judges will be smart enough to tell the difference. :)
Given that XP stops getting security patches in April and will then be even more of a problem in terms of botnets , not to mention a security issue for anyone using it , I think a strong case can be made that no, it's not better to give people modern evolving anything on XP.

They should feel like they are living in the dark ages, devoid of modern luxuries and subject to the whim of any thug that comes along ... because they are or soon will be.

yawn - another article slamming the "lean startup" approach, written by somebody who clearly doesn't have a clue about the "lean startup" approach, but somehow still appears to have an axe to grind.

Senate approves bill to end shutdown, avert possible default
We're aware of the many similarities people will want to draw with Copenhagen Wheel but allow me to introduce some important differences as well:

1) Smart Wheel introduces a brand new electric motor that is thinner and lighter (and more efficient) than any other before it. Copenhagen Wheel uses regular rotary motor that's heavy and cumbersome, not to mention it's not a replaceable wheel - it comes together with the whole bicycle.

2) The GPS module might seems like the only thing that separates the Smart Wheel from the Copenhagen Wheel (it's not) but it's the difference of how they use this data that makes all the difference. Smart Wheel uses GPS data to learn about your cycling habits and routines and then suggests on how to improve them. This data can also be used to help improving the cycling experiences of other people. Copenhagen Wheel measures noise and air pollution levels and uses them for statistical purposes only.

3) Smart Wheel is opensource which means our users will be available to develop their own apps and other tools to find new innovations to using the Smart Wheel. We're already working closely with Pebble Watch and other similar devices are in the works, too.

4) Last but not least, despite being around for ~5 years, Copenhagen Wheel is still only a prototype with no sign of ever being available to the market. Smart Wheel is becoming available in May 2014.
It's a stretch to call this an attempt to explain matter-antimatter asymmetry.

First, let's start with how fermions (spin 1/2 particles like electrons and quarks) get mass. They get it through a coupling with the Higgs boson, and the strength of that coupling determines the particle's mass. Neutrinos are fermions, so they could get their mass in the same way. However, that would require a coupling to the Higgs much, much, much smaller than any other fermion has, and so it's a bit of an unsatisfying solution.

However, neutrinos could be their own particles (Majorana particles), as the article mentions. If that's the case, they can acquire mass in a different way than all other fermions. Some of the mechanisms (called see-saw mechanisms) that lead to small neutrino masses predict the existence of heavy neutrinos (so heavy that we haven't observed them).

Now, a heavy neutrino would decay to the lighter particles we see today. So there aren't any around anymore. But in the early universe, shortly after the big bang, there was enough energy to create them.

Particles can preferentially decay to matter instead of antimatter. It's called CP violation, and we observe it in things like heavy mesons. So if the heavy neutrino violates CP when it decays, then that could lead to our universe being made of matter.

But I've strung together a lot of hypotheticals:
1. Neutrinos must be Majorana particles.
2. Majorana neutrinos acquire mass through a see-saw mechanism with heavy neutrinos.
3. Heavy neutrinos violate CP when they decay.

This experiment might answer #1.

Number 2 would probably require studying cosmology. The mass of the heavy neutrinos is probably greater than we could create in a collider on earth (like grand unified theory scale).

For number 3, it can be argued that if we observe CP violation in light neutrinos (in this case, CP violation would mean neutrinos oscillate differently than antineutrinos), then heavy neutrinos should exhibit it, too. But we're still trying to look for CP violation in light neutrinos. And it's not clear that CP violation in light neutrinos must imply that heavy neutrinos do it, too.

I agree that finding out the nature of the neutrino is important and really cool, but I've always thought trying to argue that double-beta decay experiments are going to solve the matter-antimatter asymmetry problem is hyping things a bit too much. Isn't potentially measuring the mass of neutrinos cool enough?

I am very confident that it would fall.

Consider the slinky again. If I dropped it with a parachute to slow it.... no, replace "parachute" with "my hand", but assume my hand follows the same trajectory the parachute would... the end of the slinky would not wait for my hand to approach it. The information about a change (the drop) would take the same amount of time to reach the end of the slinky. The information travels just as fast, even though the information is "we're falling slowly" instead of "we're falling".
