If making people realise that their basic rights are being trampled makes me a traitor, then I'd want to be a traitor any day...

Ubuntu Edge Smartphone Funding Trends Low

ChristW Re:Looks nice; way too expensive (251 comments)

A contract with your carrier with a 'free phone' attached costs about $50 a month, so (those are usually 2 years...) cost $1200 in two years. If you get a SIM-only contract (is that possible in the US?), those are $5 to $10 a month, so you save $800+ in 2 years. Hey, that's enough to buy an Edge, right there!

Austrian Blank Media Tax May Expand To Include Cloud Storage

ChristW Re:More governmental abuse in Europe (129 comments)

Well, I live in The Netherlands, and one of the things that we witnessed the last couple of weeks was a new law proposed by the Minister of Safety and Justice (...), Ivo Opstelten. He proposed that people who have encrypted files on their computer should be pressed into giving out their keys, "but only if they are very bad criminals, like when hiding child porn or are terrorists". Oh, so, that's OK then...

Why Dissonant Music Sounds 'Wrong'

ChristW Re:Consonance (183 comments)

Yes, there _is_ such a thing as perfect consonance in music, but _not_ on an instrument with restricted frequency generation!

If you sing, or play a flute, or a violin, you're able to generate a much larger range of frequencies than when you play a piano. That way, you can, and should, create 'perfect consonance'. Note that this is a lot harder than 'hitting the right key on the piano'! And if you get it wrong, the beatings get annoying very quickly.

I've been told that 'the only way to get two flautists to play together nicely is to shoot one of them'.

Attack Steals Crypto Key From Co-Located Virtual Machines

ChristW Not just 'a' crypto key (73 comments)

The published paper is an interesting read. Obtaining the crypto key to libgcrypt is only one application. In general, the authors say, it is possible to construct a side-channel attack on other, unrelated, processes in the attacked VM.

OpenMoko's FreeRunner Rises From the Ashes

Skype Bypasses Windows 8.1 Lock Screen

Quantum-Secure Authentication with a Classical Key

ChristW ChristW writes  |  about a year and a half ago

ChristW (18232) writes "This paper describes how a quantum-secure authentication can be achieved using a (physical) key containing a PUF (Physically Uncopyable Function, consisting of a random 3D structure of nano-particles). The setup uses a low photon-count wavefront to make skimming and flooding of the system practically impossible. From one of the authors is also the paper 'Towards more aesthetic forms of cryptography', which is also a good and funny read."

McAfee Fears Torture By Belize Police

ChristW ChristW writes  |  about 2 years ago

ChristW (18232) writes "Famous software engineer John McAfee, known for his line of anti-virus software fears for torture by the Belize police force. Last Sunday, his neighbour's body was found in a puddle of blood. Police told him that he is not a suspect, but they want to interrogate him none the less. McAfee fears that the police wil not hold back on torture methods to get him to give them any information. When his farm was raided, he dug himself into the ground and put a box over his head to keep from being found.

He tells this in interviews that are published on CNBC's and Wired Magazine's websites."

Dutch DigiNotar servers were fully hacked

ChristW ChristW writes  |  about 2 years ago

ChristW (18232) writes "The final report that was handed to the Dutch government today indicates that all 8 certificate servers of the Dutch company DigiNotar were fully hacked. Because the access log files were stored on the same servers, they cannot be used to find any evidence for or against intrusion. In fact, blatant falsification has been found in those log files.

A series of so-far unused certificates has also been found. It is unknown if and where these certificates have been used."

Call To Arms: Free The Internet!

ChristW ChristW writes  |  more than 2 years ago

ChristW (18232) writes "We've been on the slippery slope for some time now. SOPA and PIPA, the MAFIAA, BREIN (in The Netherlands) shutting down links to sites, and shutting down sites that link to sites that have instructions on them, the DeCSS debacle, the Sony Rootkit debacle, you name it...

The companies and governments are acting like little children (taking the Internet for their own intentions, and not sharing it).

I say, we do what we do to little children. We've given the Internet to the corporations and governments, it's time to say 'Bad girl!' and take it back from them.

So, what can we do to wrestle the Internet from their hands?"

Developers for GTA04 (OpenMoko successor) needed!

ChristW ChristW writes  |  more than 2 years ago

ChristW writes "In a recent article, I presented you with the OpenMoko Freerunner's successor, the GTA-04.

The project is in dire need of (kernel) developers to help out with drivers, suspend/idle time and userland applications, or any other area you may be interested in.

A limited number of free (as-in-beer and, of course, as-in-speech) GTA04 main boards is available for people who want to help move the project forward. Having a GTA01 (Neo1973) or GTA02 (Freerunner) is optional, but having one will enable you to convert your existing phone to one with the new main board.

If anyone is interested in obtaining one of these boards, please let me know!"

The new hardware features:
- DM3730 (800 MHz)

Microsoft further reducing MSN Music support

ChristW ChristW writes  |  more than 6 years ago

ChristW (18232) writes "The aricle itself says it better than I can: "In November 2006, Microsoft stopped selling music downloads through its MSN Music site, directing people to the Zune Marketplace instead. But customers who had already purchased tracks through MSN Music have been able to continue getting license keys to transfer and play their songs on additional computers. After Aug. 31, no more will they be able to do that, according to an e-mail notification sent to customers today."

The e-mail that Microsoft sent can be found in the original article"

ChristW ChristW writes  |  more than 7 years ago

ChristW writes "A security expert currently working at the Philips Research lab in Eindhoven has set himself a new challenge, making encryption and decryption more aesthetically pleasing. From the introduction to his paper: "When a scientific or engineering discipline reaches a high level of sophistication, it ceases to be a purely function-oriented endeavour and acquires certain aesthetic qualities. Consider for instance robotics. The elegant and efficient motions of sleek robotic arms are delightful to watch. Another example is fractal art. The difference between a sophisticated and an immature discipline is like hearing a song instead of mere speech, reading poetry instead of mere words, seeing a sculpture instead of mere stone. Cryptography has clearly not yet reached this state of maturity. Not by a long way. Instead of being delightful, it a is messy, painstaking, boring, arduous business for all involved parties, especially for the cryptanalist. I hypothesize that when cryptography reaches a sufficient state of maturity, reading and analyzing ciphertext will be akin to submerging oneself in a profoundly poetic work of art. Cryptanalysis, even if unsuccessful, will fill the practitioner with joy, while the encrypting and decrypting parties will delight in the beautiful relationships between the plaintext and the ciphertext." See the paper on his home page for an example and his conclusion."
