Privacy and anonymity
I have decided to post few words about freedom in the internet. As almost all of you probably know government agencies ant private corporations gained extreme insight in every part of our internet activities. There are more and more information's about abuse of power (Aaron Swartz), illegal eavesdropping (Bruce Schneier) and so on. But despise despite all that shitstorm we still have few tools that can help us gain more privacy/security/anonymity (you name it).
First one that I would strongly recommend is Tails
Tails is a live operating system, that you can start on almost any computer from a DVD, USB stick, or SD card. It aims at preserving your privacy and anonymity, and helps you to:
use the Internet anonymously and circumvent censorship; all connections to the Internet are forced to go through the Tor network;
leave no trace on the computer you are using unless you ask it explicitly;
use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging
Visit their website download it and play with it a little. Donate. https://tails.boum.org/
Bitcoin is a digital currency, meaning it’s money controlled and stored entirely by computers spread across the internet, and this money is finding its way to more and more people and businesses around the world. But it’s much more than that, and many people — including the sharpest of internet pioneers as well as seasoned economists — are still struggling to come to terms with its many identities. With that in mind, we give you this: an idiot’s guide to bitcoin.

Bitcoin Hits the Big Time, to the Regret of Some Early Boosters
By Tom Simonite on May 22, 2013
Bitcoin’s earliest adopters were libertarians, cryptographers, and coders attracted by the idea of money that could operate without government oversight. They liked the idea that people could exchange bitcoins without knowing or trusting one another. Large exchanges and payments companies that operate much like existing financial institutions and follow the same regulations compromise both of those features, some argue.
“When those people talk about revolution, it’s ‘I put out a disruptive app.’ That’s not a revolution to me,” said one attendee, who told me that his online handle is Alexmat and that he quit a job with Goldman Sachs’s commodity desk in Tokyo to operate a private, one-man Bitcoin exchange business in Seattle. “These companies would be happy for it to just function like Mastercard. That is not what Bitcoin is about.”

When I have to explain what is Bitcoin two words I say it is an internet cash. As cash, you own it peronaly, you pay without intermediaries and without fees if desired andanonymous. As an internet cash it also enjoys the digital world benefits - easy to move, do not take up much space, you can...
The mining speed of the bitcoin network on bitcoinwatch.com passed 1 exaFLOPS (1,000 petaFLOPS) this week — more than 8 times the combined speed of the Top 500 supercomputers, The Genesis Block reports.
(FLOPS stands for FLoating-point Operations Per Second, and is frequently used as a standard to measure computer speed. Bitcoin mining uses an integer calculation and almost no floating-point operations, so converting bitcoin network speed to this standard is somewhat clumsy.)
The FLOPS estimate is based on the opportunity cost of computers using their hardware for mining instead of other applications. Miners are using their graphics cards to perform hashes instead of other FLOPS-based distributed computing. Therefore, a conversion rate of 1 hash = 12.7K FLOP is used to estimate what this hardware could be doing.
One of the first bitcoin operators to realize that the bitcoin eco-system needs to be simple to use for wider adoption. Still no EU-payments, otherwise I’d be using it already.
How A Bitcoin Transaction Works

Other crypto-currencies
Ian Steadman from Wired UK made good guide to alt currencies that seems to be most popular nowadays.
Here you have sample of his writing:
For all the Bitcoin hype, it's not hard to see that there's a big problem in how bitcoins are actually used. That comes from Bitcoin being both a currency and a commodity in its current guise. Its rise in value has been the thing to make it famous, but that's also the thing that has undermined its usefulness as a currency. But if you're someone who wants to accept bitcoins as part of a business, then having to update your prices every minute isn't necessarily useful -- nor is the worry that deflation might discourage coins from circulating, or the worry that the whole thing could pop without warning.
Businesses have started accepting Bitcoin, to their credit. There's a whole neighbourhood in Berlin that's seemingly converted on mass, while the range of online services that accept it -- from Wordpress to OK Cupid -- is now long enough to be essentially pointless in listing, again significant in showing Bitcoin is now a legitimate currency.
We may be entering a new period in how we pay for things online, with Bitcoin as the first example of theory put into practice. Like many new and radical ideas, its implementation has been sketchy, inconsistent, with naysayers decrying it as a scam or a Ponzi scheme, its acolytes proclaiming it a crucial weapon in the liberation of the individual from the corporatist banking system and government regulation of commerce.
This argument sees Bitcoin as to currencies/online markets as Napster was to music piracy. The popularity of Bitcoin might well have put the whole system under an immense amount of stress but the underlying concept is an attractive one -- a cryptographically secure and anonymous currency that doesn't take a cut from transactions (like, say, Amazon's virtual currency), and which remains independent of any single, central authority.
For many people, the risks -- from fraud, for instance -- are outweighed by the benefits. So let's say you're not convinced by Bitcoin as it is, but you still like Satoshi Nakomoto's idea ("an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party") then there are other alternatives out there. Here are some of the more interesting ones, all forked from the original Bitcoin code.

Have a look.
What other digital currencies are there?
Bitcoin might currently be getting the lion’s share of media attention, as far as digital currencies go. But it’s not the only form of electronic money being mined, traded and spent.
Note : Not all cryptocurrencies are created equal and some are created solely to rip you off. Be careful with alt-currencies as some carry malware while others are pump/dump coins (if you didn’t pre-mine or get in very early — you lose).
Never download a client unless you know for sure someone respected in the community has looked over the source code and scanned the application.
Do not click links in the forums unless you trust the op.
Research yourself. I have found the following alternative block chain clients/coins to be fine and have mined all of these at some point.
Litecoin
Feathercoin
PPCoin
Novacoin
Namecoin (higher learning curve)
Here’s a good post on this subject at bitcointalk.
