Cost of Education

An article at Mashable  “In the Future, the Cost of Education will be Zero” doesn’t bode well for institutes for higher education. Universities are a different matter, as higher education used to be free in Germany and still is in countries like Sweden – also top students in any country. In the long run, costs will naturally decrease, but I don’t see language teachers being replaced by videos anytime soon. Also, lower costs don’t mean the price will fall as well – especially in education, a high price tag signals quality. Many of the courses universities offer though could be replaced by open source and keep down overall costs – readings first and foremost. Also, education could be introduced to a broader spectrum of the population, but then again, a certain mindset is neccessary to watch an MIT Video lecture about Classic Mechanics instead of a mundane Big Brother episode at Youtube.

A commenter argues that “automatization can go only so far” – but logical essays i.e. can’t be evaluated by a machine. Nevertheless, PearsonVue is attempting exactly that with the new Pearson Test of English. If it’s technically feasible, I don’t see a problem evaluating other forms of academic production as well, verbal or written.

Still, I’ve had the opportunity to both experience face2face as well as online courses: The biggest advantage is direct intellectual exchange between students working on a case – not doable with today’s tools. Many textbooks are definitely going to be free in the future, it’s just a long way. Education is certainly going to get cheaper – but as long as teachers need to be paid and class rooms needed for social interaction, institutes for higher education are not going to be able to offer completely free courses.

Google Chrome

Google Chrome arrived – the second browser war, if it hadn’t already started with the emergence and success of Firefox, has now officially begun. I think Google Chrome is rather a huge social experiment than a browser – what’s more important, your privacy or the (second) best browser?

Reading CNET’s 10 Things we’d like to see in Google Chrome, I already know what I’d like to see in it but won’t ever be part of the software… a decent Adblocker.

Transrapid Worldwide

Nothing could better symbolize the German economy better than the Transrapid: Domestic demand and overall mood are down, but export is booming. This “new” transportation technology which could easily rival airplanes with its 500km/h for medium distance destinations is waiting since the late 80s to take off. In it’s homecountry, indecisive politics and a hesitating economy lead to a complete standstill, no maglev track beside the testing ground in the Emsland was built. The train is not compatible with the current system, building a railroad track from scratch would necessitate huge amounts of investment. On the other hand, maintenance cost and energy consumption is said to be quite lower, beside the speed gain. Environmentalists have been criticizing the project, but in comparison the maglev doesn’t look bad.

Bought by China in 2000, the Transrapid serves passengers travelling from Pu Dong airport to Shanghai, but the government thinks about extending the route to Hangzhou, which is 180km away. Also, Spiegel Online reports about plans to create maglev tracks in the United States and Great Britain and possibly in the Middle East. One of two plans to build a track in Munich is seemingly still in the air, but don’t hold your breath.

The site deserves its name – as soon as you start trying it out, you’re hooked. Based on the Music Genome Project, they listened to and categorized over 10,000 songs with attributes like influences by [insert music style here], mild rhythmic syncopation, electric instrumentation, extensive vamping, minor key tonality, antiphony, etc. etc.

Opera for Free

Opera’s state-of-the-art web browser is going to be free from today. They removed the ad banner and the licensing fee, as those two seemed to be the main reasons that limited Opera’s acceptance. The company is still making revenues though. It started with an online party where you could grab a free key for the browser, but it seems the company understood that they never could rival Firefox with their current business model. It’ll certainly cost them in the short run, but if it spreads out enough and grabs a few % from IE, it could work. Since IE 7 beta is going public on December 7th, things finally got into motion.

eBay swallows Skype for $2.6 billion

That’s a lot of money. Skype has over 50 million users, but $2.6 billion is certainly 50 times more than they earn in revenues. I can see eBayers using eBaySkype to contact each other, but honestly, how well do you understand mictures like Denglish, Konglish, Engrish, Chinglish, Spanglish, Franglais, Indian English and other variations?

Crooks and Liars – Bittorrent

Since last week, I’ve been trying to get as much information about the hurricane Katrina disaster as possible. I’ve stumbled over a weblog that regularily publishes news snippets from CNN, FOX, MSNBC and others. Crooks and Liars by John Amato is very critical of the current U.S. government and the style of the postings might not be everybody’s taste, since they get explicit at times – but the weblog certainly raises a lot of valid questions about how the government responded to the disaster.

Seeing the number of videos they offer for download and the high number of visitors, I thought their server must have been under lots of stress lately. I emailed to the weblog’s author and suggested to use torrents for distribution. Bittorrent and similar clients are programs for easier distribution of huge files. Since many use them to download movies and songs, RIAA and MPAA are trying to sue operators of websites that host torrents, which are neccessary for clients like Azureus to “find” the file in question and download it. The websites that offer those torrents are quite easy to find, just google for it.

In spite of the entertainment industry opposition to the torrent technology itself, there are lots of legal uses, as can been seen at Legaltorrents, also, the beta version of World of Warcraft, Planetshift (a free, cross-platform MMORPG) and the fan-film Star Wars: Revelations have been made available through torrents. The basic idea this technology is founded on is great – everybody in the network shares his file with everybody else. In the end, everyone gets his file faster and supports others in doing so while the peers in the network with complete copies have a lower traffic load. Visiting Amato’s weblog again this morning, I found torrent files all over the place. I’m not a lawyer, but I assume the files offered there can be considered legal, at least in the U.S. (it might fall under fair use), but I’m curious about other countries, like Germany.

Infestation

We’re back. There would be lot to write about (in short: it was great, Belgium is a great country), but one mishap on Tuesday kept me busy until today. After my first post from our host’s computer on Monday, I’ve been told that the computer has problems.

Several dozen viruses, beside Sobig, AntiSpyware Viruses, Trojans and as far as I could tell, keyloggers as well. Since I couldn’t rule out that my passwords for Blogger and several Emailaccounts were compromised, I spent the day with changing all of them. It was time for reneval anyway, but it hits you when you least expect it.

Bionic Man Moves Artificial Arm With Brain

Science follows fiction. It’s not exactly the Six Million Dollar Man, but it’s getting there:

The world’s first bionic man, Jesse Sullivan, 54, accidentally touched live wires while working as a utility lineman in Tennessee. He suffered severe burns, causing him to lose his arms.
[...]
When Sullivan’s brain tells his arm to do something, it’s done in seconds and he has feeling in the bionic arm.
[...]
By the time it’s perfected, the cost of manufacturing the bionic arm is expected to be about $6 million, according to the report.

The hospital’s website has several videos about the procedure and the results. Give it a few years and people might feel and look natural.

P2P SIP

This could be the next big thing. P2P and standard technology. There’s a detailed analysis of the Skype network as well (quite technical). I hope Xten or some other company will create a client for it, I’m using Skype, but I principally don’t like proprietary software that much. Skype is so successful because the installation and usage is a piece of cake, a little bit of competition wouldn’t hurt.

Sim Brain

blue brain projectHow many Joe Average processors do you need to accumulate the equivalent of 22.8 teraflops (one trillion computations per second) of calculating power? I have no idea, but this one can do it alone – and simulate a human brain. One of the benefits the science team aims at is cracking the neural node, which basically means to understand how the brains works, how it uses electrical signals, how our memory works. It might even help to answer question like how selfconscience and our perception of reality are constructed, how intelligence works? Questions philosophers thought about it and tried to answer and give definitions for thousands of years. The project is not about creating a thinking brain, some kind of computerized artificial intelligence, but still, just the thought of being able to simulate the brain was pure science fiction a few decades ago. You’re mentally ill? Let’s take a closer look…

It will be the first time humans will be able to observe the electrical code our brains use to represent the world, and to do so in real time, …
[...]The end product, which will take at least a decade to achieve, can then be stimulated and observed to see how different parts of the brain behave.

Behind the Curtains…

This weblog is going to get a new home soon. I reserved the domain grabic.name, since my internet provider, 1 & 1, supplies its customers with one free top-level domain. I’m also thinking about using Wordpress, NucleusCMS or Serendipity in the future. Blogger is a great – free – service, but it’s too limiting.

Stranded

What to do when you boot up your computer and there’s no internet connection? Two days ago, our phone line went dead for an hour, after that internet was down until a few minutes ago. If you didn’t change your DSL settings, the hardware doesn’t smell or look charred, the software is untouched, then there’s not much one can do: Sit tight and wait. Telekom customer support can check basic DSL availability, so that’s what I did and called them. The storm yesterday night must have broken something since there are outtages all over the country. If you’re lucky and have alternative internet access (a modem or an IT cafe around the corner), take a look at this website next time. Currently there are still some people in my area having DSL blackouts.
