This was posted on reddit today. I agree entirely with the poster’s sentiment: interesting links on reddit are, more often than not, not links to the gateway of a whole website of interesting stuff. When they are links to a website’s front page, it’s generally a very narrow, single-purpose website that is quickly forgotten about. Hopefully, the poster’s subreddit — apparently yet to be made — will be a success.
In any event, having gone through the blog-post he had linked I decided to share some of my new discoveries here myself:
I feel I must write a disclaimer, saying I haven’t used or read these sites extensively, having just discovered them a few hours ago, but from first impressions they do look like they deserve a bookmark.
At the moment in Germany, there is fierce opposition growing against plans by the CDU to implement internet censorship under the guise of attacking the spread of child pornography. A movement championed by the German Piratenpartei has dubbed ex-minister for family affairs Ursula von der Leyen “Zensursula”, a portmandeau of Zensur (Censor) and Ursula, and is referring to the CDU’s plans as Stasi 2.0, a nod to the brutal secret police which operated in former East Germany.
Not only is there to be a secret list of blocked websites, such as exists in Australia, but the government is pushing for more data to be collected from citizens and retained for a long period of time.
A video which caught my attention a while back was entitled Du bist Terrorist (You are a terrorist). With soft ambient music playing, and deceptively pleasantly designed imagery, the two-minute video parodies the Du bist Deutschland ad-campaign with a soft, reassuring voice informing you of what the German government has in store for you, in terms of heavier and more invasive surveillance — because You are a terrorist.
Earlier this week I found that the same people had created a new video in the same vein, entitled Rette deine Freiheit (Save your freedom). The video focuses much more on the coming internet censorship in Germany than just data retention and physical surveillance.
Since there was no English translation available, I decided to translate it and re-upload to Youtube. The result is below:
The translation is by no means perfect, but at least it’s something. There were a few tricky problems with it:
In any event, there’s likely to be an official translation soon (I just saw an “Englisch (bald verfügbar)” notice at the top of the official page now — perhaps my emailing asking for a transcript of the video got them in a rush) and these issues will cease to be.
One last thing — if you are interested in learning more about the situation in Germany regarding internet freedom and the child pornography scare, I’d not only urge you to visit the links above, but also this shocking, but morbidly fascinating account of one techie’s work in the murkiest of subcultures. Thankfully, he doesn’t go into detail about actual child abuse, but instead details exactly how child pornography rings work, using the internet and computers.
Put simply, it proves what anyone with a clue already knows: current proposals for internet censorship will have absolutely no impact whatsoever on paedophiles and child pornographers and will only serve to infringe the rights of normal, law-abiding internet users.
Thanks to Áine and Patricia for help with one or two minor parts of the translation.
Peter Ablinger, an Austrian composer currently residing in Berlin, has done something rather interesting: he made a recording of a child reading the Proclamation of the European Environmental Criminal Court, then invented a mechanical piano player capable of reading notes in a very high time resolution from a computer.
The computer performs a frequency analysis of the sound spectrum, aided by Ablinger himself, which is then fed into the piano player and out comes the child’s voice.

While I wouldn’t have much hope for people trying to work out what the piano is “saying” without the aid of seeing the words as they’re heard, I think it’s a pretty interesting experiment. The auto-player in itself is something to be marvelled at. Neat!
An entertaining talk from Luis von Ahn, the guy behind CAPTCHAs, about the reinvention of the idea in a way to benefit mankind. Some pretty incredible statistics throughout, especially towards the end.
Stumbled across this very detailed description of what exactly happens when a HTTPS connection is established between a client and server. It includes a well written, easy-to-read description of the mathematics behind RSA public key cryptography.
Worth the read!
At the moment I’m looking to begin using a local email client on Windows again. I was going to use Mozilla’s Thunderbird, but it appears to be rather bloated, and apparently fails at finding emails when there’s a few thousand to search through.
What I need is something lightweight that treats email correspondances as conversations (a la Gmail) and can synchronise with web email services (Gmail, Zimbra, etc).
So, what should I use?
There’s been a buzz about the internet in the past few months about Wolfram|Alpha, a “computational knowledge engine” announced in March. It’s been put together by Wolfram Research, the same people who came up with the Mathematica programming language and the project is headed up by English physicist Stephen Wolfram. It seems to be due to be released in 4 days, on the 18th of May, 2009. Today, a video was released demonstrating the power of the tool.
I can honestly say I’ve never seen anything in computer science or computational linguistics (question answering and information extraction are rather busy fields of research in CL) that’s impressed me so much. The sheer power, flexibility and ingenuity of the engine is indescribable.
The opportunities for computer scientists it will open up, once it’s released, are also endless. If the project can take the strain of its inevitable popularity and keep advancing at the current rate of development, I dare say it’ll be a definite watershed moment in the history of the internet.
