A bill is only worth as much as you decide it's worth. We both have to agree on a method of payment in order to fairly exchange goods. Bitcoin is a method of payment.

When someone sends you Bitcoins, your bitcoin software will decide whether they are fake or not. Since the entire transaction history is public, it can find all transactions to and from the person who is sending you coins, and see if they indeed have enough to pay you.

The problem is that, at first, nobody had coins. To get them into circulation a system was built: For finding a "proof of work" (just assume for now that it's something that takes a computer a certain amount of work to find), the program agrees that you earned an X amount of coins. It used to be 50 coins per proof of work, right now it's 25. It will get down to zero eventually and there will be 21 million coins in circulation. Never more.

A proof of work is easy to validate. It's like a big number is given, and you have to find its prime factors. It takes forever to search all possibilities, but once they're found, you can easily multiply them to check the validity.

So when you are sent coins, your Bitcoin program (called the bitcoin client) will check the transaction history for who found proof of works, how much they gained from it, and who sent coins to who. After this you know how much money someone has, and whether he can pay you.

It's up to your bitcoin client to use the same rules as everyone. You can decide that proof of works are worth much more or much less than everyone else agrees upon, but it will only prevent you from using the network. Most, ifnot all, other clients will reject your version of the truth.

I hope this cleared things up. It probably rose other questions, but most are asked before. Just google for it ;)

I also wrote a blogpost about Bitcoin, if you are interested: http://lucb1e.com/?p=post&id=99
I like you and I wish you luck. Your target audience is a guy like patio11 who has a 500 dollar course with an ebook and videos and who will probably release more info products? My advice would be to talk to and/or try to sell patio11 on why he should use your service and then bring that back to your design and copy.
Then why didn't you buy a Windows 7 tablet from before? Just because it didn't have a touch oriented interface? The "OS" interface wasn't the main problem for Windows tablets. The millions of apps that are still made for a PC interface were (and still are) the problem.

So if that's the apps you say you wanted the iPad to have, then Windows 8 doesn't solve that problem at all. And if you actually care more about the "tablet" apps, then the iPad and even Android has a lot more of those, too.

iOS and Android have been rewritten from the ground up to work well on "low-end" hardware (relative to mainstream Intel/AMD CPU's) and for the touch paradigm. Windows 8 wasn't rewritten, and the bloat is being felt even on "high-end ARM chips", and the "legacy programs" feel like they are being dragged once again onto the tablet paradigm, where they never belonged.

Khan Academy

Mountain View, CA - full-time and intern, designers and devs

We're a non-profit whose mission is to provide a world-class education to anyone, anywhere. We're scaling quickly. Our students answer over 2 million math problems per day (over 950mm total so far), all generated by our open source exercise generation framework (https://github.com/Khan/khan-exercises), and our videos (now from a variety of authors including Sal) have been viewed over 220mm times. We're tracking all that data and using it to customize each student's experience as well as building brand-new tools like our new programming environment (http://ejohn.org/blog/introducing-khan-cs/).

We could use your help. Working for Khan Academy is one of the highest educational impact positions you can imagine, and we've been called by Wired one of the best places to work in Silicon Valley: http://news.ycombinator.com/item?id=4157078.

We're hiring designers and all types of devs -- mobile, frontend, backend, data scientist, whatever you want to call yourself.

Big plans ahead.

Responsive design sounds like a glorified switch clause: instead of making good fluid design which scales you essentialy fork your webpage design into multiple versions, and swap between them based on screen size. Seems like a bad idea to me.
It's not in defence of the OS - it's a rebuttal to the people who ignore all the other benefits of upgrading to a newer OS and cite the (often repeated) notion that the desktop as we know it is gone for good.
Why not ask yourself the question "Why Cassandra?" or "Why Riak?" or "why you are specifically looking at these two alternatives"
for the task at hand.
This way you know what each of these could do for your situation. Once you have established that, it will be easier to look at other factors.
How necessary would speaking fluent German be to live/work in Berlin or Vienna? I've heard that most young people and tech people speak English, but that it can be a problem, if you don't know good German, to interact with the civil service, banking, business registration, and those kinds of things. But I have no personal experience there.

One thing that makes it easy to stay in Scandinavia is that I've been rather spoiled by how easy it is to do everything in Denmark in English. Official government forms are available in your choice of Danish or English versions, all my banking is in English, doctors all speak it, and every government office I've been to will switch once they realize you're a foreigner. Heck, even many public lectures at universities and museums are in English. The language is good to know for social reasons, but there aren't really any formal/official situations where you have to interact in Danish.

New York, NY -- IT consultant for managed services provider

We're a fast-growing company providing IT consulting and helpdesk services for small businesses in the NYC and north NJ area. It's a "level 3" engineer job- you'd be taking escalations from the 1st and 2nd tier techs when they weren't able to solve problems themselves; mentoring them on skills they should know; advising clients on the best ways to improve their infrastructure, and implementing solutions to some fun projects (getting those 8 dusty old DL 320's out of someone's rack and onto their very first VMware deployment!)

The right candidate will need 3+ years of experience in a helpdesk or service delivery environment; proven skills with Windows servers from 03-08, including Active Directory, Exchange, DNS, DFS, WDS would be cool.. and experience with multiple server environments. Know what a firewall is too- Sonicwall experience would be great!

Be a good communicator, superior troubleshooter, able to work under pressure, and really want to be part of a team.

I'd love to talk to you more about it if you're interested! Send your resume to ndespres@cmitsolutions.com and let's chat.

In Finland, your income tax rate only depends on your total yearly income. If you estimate your income too low and too much money gets withheld, it will be returned to you the next year. You can also adjust your estimate at any point during the year.
There are no "hard and fast rules" on fair use, just as there are no "hard and fast rules" about what makes slander, slander. Or what makes police brutality, brutal (in an illegal sense). But yet both are still against the law.

I'm not saying that it's easy to define fair use. I'm saying the OP seems to have a dishonest reading of the law if he's trying to assert that "fair use" means academia can reproduce copyrighted work and consider it "fair" because it's for educational purposes. That is completely missing the entire concept of "fair use".

In my own personal experience, designing component interfaces is the most important aspect of building a system, especially when you are working with a team. Very often, I have found that the "all in one room" development model is implemented because the team lacks the ability to define those interfaces first.
The thing is, freedom of speech, movement, etc. are much more obvious to non-technical people than freedom to run arbitrary software. I think it's sort of offensive to imply that because someone isn't aware of the implications of the app store, they aren't a "thinking person". There is no risk of being rounded up and sent to a labour camp for re-education because you jailbroke your iPhone. I'm not really sure where you're going with the possession thing, that's pretty much just a hand-wavey aphorism. Obviously possessing stolen property is not 90% legal.

I agree with you generally, that we as technical people and experts need to be aware of, and create awareness of, these issues. I think you're falling into the same trap as RMS, which is to get absurd about the abstract notion of freedom, without making change attainable or actionable for the average user. If you want to have a massive shift in user attitudes towards the App store, you're not going to achieve that by comparing Apple to China. Nor can you simply 'dismiss them as absurd', because you're alienating your audience: they think Apple is reasonable.

What I liked about Sir Tim here was that he makes the argument pretty reasonably: it sucks that apps aren't cross-platform, that you have to depend on a proprietary interface to save them, share them with other users, etc. He makes it relatable in the present, he doesn't just fall back on the dystopian slippery-slope argument.
FUD? So you're implying that Microsoft giving users a lot less space than they are promoting in commercials and on the label a lie?

Yet another obscure Economist diagram! I really like the Economist -- indeed, I'm a subscriber -- but they do need someone like Tufte to give them advice on making decent understandable diagrams.
I'm typing this on a 2009 mac pro. I bought it back then, because at the time it could do everything I wanted it to - snow leopard was fairly new, and as a programmer / photographer, a *nix box with a gui was pretty much my sweet spot. But as the newer os x versions have been released and they have stopped updating the mac pro line, its becoming less appealing as a power user as time goes on. My next purchase probably wont be a mac. I completely realize that I am no longer their target demo, but I don't like my overall options really. But the fact is, for the majority of what I do, a windows 7/8 box with enough power to run linux vms is my best option.
We've been working on this for a number of years, so you can't imagine how good it feels to have the big picture coming together. I'm happy to answer any questions about eg "when should I use sync vs regular REST API style network programming?" etc etc.
I was an early adopter of Couchbase Mobile for native iPad apps. Seeing Couchbase (Lite) now syncing to iOS, Android and with a plugin for Cordova to HTML5 apps is really awesome for offline data and synchronisation.

There's a hilarious scene in The Guard (http://www.imdb.com/title/tt1540133/) where all of the Irish Garda are trying to seem very respectful of Don Cheadle's FBI agent, except for Brendan Gleeson's Garda who mercilessly takes the piss out of him. Later he says, "Now I know what you're thinking. You're thinking, these men are armed and dangerous, and you being an FBI agent you're more used to shooting at unarmed women and children."

These two pieces of code should have around the same performance:

$( ".widget" ).css( "color", "green" ).css( "font-size", "16px" );

$( ".widget" ).css({
"color": "green",
"font-size": "16px"
})

Fact is, jQuery also has to loop through the object and assign each css style declaration, so the performance is very similar.

A comment on El Reg suggest it has to do with tool-less access to the inside where there are wires and running fans. Another raises a valid point that regulation like this is sometimes good for the companies as when something bad happens to the consumer they can just point to the regulation and say we've done what is required by the law.
I actually own a Surface RT and I like it. I get the feeling that a lot of people try out Windows 8 or the Surface RT for a few minutes and pan it as crap. There's definitely a learning curve associated with it but the payout is that it's got advanced gestures that allow you to do more without a keyboard.

One thing that could be impacting sales is that you have to go to a Microsoft Store (brick-and-mortar) or online there to purchase it. There is no try-before-you-buy experience unless you're lucky to live close to one of those stores.

As for the storage space what I've noticed is that I need just enough space locally to have certain files available to me. So local storage for me is basically a cache where I keep most of my documents in the cloud.
