Finally my tax euros working for me—free wifi on the train

Filed under: IT,Technology by Branko Collin @ 9:28 pm

Once we escaped the Schiphol airport tunnel earlier today, not just did I get to enjoy 5 minutes of free wifi, but Dutch rail was kind enough to tell me where I was, and where I was heading.

March last year the first Dutch Rail train was outfitted with free wifi. By then other European rail operators had already introduced wireless networking on their trains. In the Netherlands, both Arriva and Connexxion managed to get to the wifi grail before Dutch Rail. Arriva’s and Dutch Rail’s implementations are heavily sponsored by the national government.

Delft students aiming for space with amateur rocket

Filed under: Technology by Branko Collin @ 2:52 pm

In 2009 students of Delft University broke the European amateur altitude record with a rocket called Stratos. In 2012 they wish to get halfway the edge of space with a rocket called Stratos II.

The students, members of the Delft Aerospace Rocket Engineering association, successfully tested propellant at artillery range ‘t Harde during DARE Launch Day, two weeks ago. Stratos II will be a two stage rocket which will be launched in Norway in 2012.

DARE launched five rockets at its launch day, all of which contained an egg. Two of the eggs survived.

The first amateur rocket to reach space was the GoFast rocket (2004), built by the Civilian Space eXploration Team of the USA.

Wooden iPad 2 cover

Filed under: Gadgets,Technology by Branko Collin @ 10:10 am

Hot on the heels of the announcement of Apple’s latest toy comes this wooden cover for the iPad 2 by Dutch manufacturer Miniot. It works like Apple’s own Smart Cover, as it uses magnets that attach to the tablet, and the cover can be rolled up to function as a stand.

The Schagen, Noord Holland based company sells them or 50 euro or more. There’s a video that shows you how it works.

Nineteenth century X-ray machine put to the test

Filed under: Technology by Branko Collin @ 1:28 am

In 1895 high school director H.J. Hoffmans and hospital director Lambertus van Kleef from Maastricht decided to build their own X-ray machine, just weeks after Wilhelm Röntgen’s famous discovery. Gerrit Kemerink of Maastricht University has now fired the old beast back up again and managed to coax some good pictures from it. The BBC has both images of and by the machine, and reports:

Given that a high radiation dose might be required to carry out the tests, the team obtained a hand from a cadaver as their imaging subject – rather than the “young lady’s hand” listed in Hoffmans and van Kleef’s notes.

The team accordingly found that using a modern detector, a radiation dose 10 times higher was required from the antiquated system when compared to a modern one.

Using a photographic plate and the same imaging conditions Hoffmans and van Kleef used, a dose 1,500 times higher was required.

In Dutch X-rays are called ‘röntgenstralen’, after their discoverer.

Van Deyssel had his staff read out his phone calls

Filed under: Literature,Technology by Branko Collin @ 3:04 pm

Mr Alberdingk Thijm (1864-1952) thought using the newfangled telephone was a little too banal for his taste. When he wanted to talk to someone, he wrote down what he wanted to say, and then let his personnel read out his notes over the phone.

His biographer Harry Prick* kept these notes, and they have now been turned into an audio book by Rubinstein titled Telefoonbriefjes (narrated by Arend Jan Heerma van Voss). Alberdingk Thijm, a novelist publishing under the name Lodewijk van Deyssel, used his technique to great effect:

To mrs. S.C. Mulder (21-12-1940): “At the tea enjoyed at your house today there were: tea, sugar, milk, orange juice, demi and triple sec, liqueurs […], and a deep plate of red porcelain with pralines, candied ginger, and all kinds of candy. Perhaps this tea would be worthy of repetition on December 30.”

And…

To Anton Bosse (39-11-1938): “Mr. Alb. Thijm requires a pipe to be delivered right away, which must be of red lacquerware and of the best quality (i.e. without black in it), and also a 5 metre long red packing tape. If you have no bicyclist to deliver at this moment, hire a cab and add the cab fare to the bill.

Can you tell me the brand name or number of Georgy’s toy railroad?”

(Reply: brand Märklin, width O, number see page 41.)

Van Deyssel belonged to a literary movement called the Tachtigers. His novel Een liefde (A Love) was considered pornographic at the time, and its reception was mixed.

*) Yes I know, ha ha. Maybe that is why he always used his initials.

Copyright vigilantes Brein seize servers illegally

Filed under: Online,Technology by Branko Collin @ 8:46 am

Dutch MPAA representatives Brein have broken the law by removing computer equipment worth hundreds of thousands of euro without a court order, law professor Ton Jongbloed told Tweakers.net last Tuesday. Brein seized 8 servers from hosting provider Al Transa last January.

The Brein foundation claims that the servers contained the warez site SWAN, although its not clear how it reasons that this makes it OK to break the law. Owner Craig Salmond says he will report the foundation to the police for theft, unless Brein gives back his hardware and offers a formal apology. His lawyer added that computervredebreuk, illegal hacking of a computer would also be a possible charge. Internet lawyer Arnoud Engelfriet sees a charge of fraud as more likely to lead to a conviction, whereas the lawyers of IT en Recht are putting their money on a charge of vigilantism.

According to Webwereld, Brein gained the ability to log in to Salmond’s servers before they took the computers. Engelfriet thinks a charge of theft is unlikely to stick, as the maintainer of the 8 computers, another provider called Worldstream, voluntarily handed the machines over to Brein.

On a totally unrelated note, in December 2010 a judge decided to keep a 16-year-old script kiddie another two weeks in jail (by now he has been released) after he allegedly had hacked websites of MasterCard and Visa in retaliation for their treatment of Wikileaks front man Julian Assange. Call it a hunch, but I have severe doubts that we will ever hear of Brein manager Tim Kuik receiving a similar treatment at the hands of his good buddies at the Justice department. I doubt he will even ever spend a second in jail, at least not for copyright related matters. He just doesn’t fit the profile, never mind that the wealthy Brein foundation is in a much better position to make the prosecutor look silly than a gormless teenage high school student is.

Groningen students build world’s largest touch screen

Filed under: Gadgets,IT,Technology by Branko Collin @ 5:12 pm

Writes the High Perfomance Computing and Visualisation department of the University of Groningen:

Scientists can now use our new enormous multitouch screen. […] We turned our existing 3D theatre with a big cylindrical screen into one that can detect 100+ simultaneous touches. We mostly used off-the-shelf hardware components and public domain software. Apparently size does matter and the result is really impressive.

[…]

Now we have such a touch screen we can use it for driving our existing software, but the initial goal was to facilitate the scientists studying Geographic Information Systems and a research group that studies interaction methods for touch screens. Having such a huge screen changes the way people interact with data and with each other. They could easily work on part of the screen in their own little environment but could switch very fast to a more collaborative approach.

Free and undetected travel with public transport chip card

Filed under: Technology by Orangemaster @ 1:24 pm

After a series of nasty blows, like bludgeoning some game monster that just won’t die, the Dutch public transport chip card has been given what mainstream media see as the kiss of death.

With a computer running Windows and a hacker’s program called LogicAnalyz3r, not only can you top up your chip card like there’s no tomorrow, but travel without any kind of detection. If you put fake money on a proper card, check in or out normally while it doesn’t register, you have yourself a ticket to ride.

“The gates and top-up devices don’t check whether actual money was transferred from the bank to your chip card. Cracking the card takes about an hour, after that, it’s just a matter of seconds.”

Yes, it’s in Dutch, but computer magazine PC-Active has written up the entire how to in a handy PDF.

TLS, the company responsible for the chip card kept saying this was ‘a hacker thing, and not for ordinary people’. If that’s not begging to be bludgeoned by hackers, I don’t know what it. TLS’ Financial Director was pathetically (yes, value judgement) quoted on telly yesterday as saying, “It’s forbidden, why would anybody do that?” Sure dude, nobody downloads from the Internet, that would be wrong.

Yes, NOS Dutch news item is in Dutch, but it’s all about the tech shown in the video.
‘Tampering with balance on chipcard is easy’

UPDATE: TLS is currently looking for a Security Officer & Fraud Manager (Thanks @AlexanderNL, @gronical!)

Samsung buys display maker Liquavista

Filed under: Technology by Branko Collin @ 1:48 pm

Dutch Philips spin-off Liquavista develops so-called electrowetting displays, a form of electronic paper that has the reflective capacities of regular paper, but the live updating capabilities of LCD screens.

Traditionally e-paper has been very slow. If you own a Kindle you know it can take a second or longer to update a screen. Animation and video need 15 updates a second to make the illusion of movement work (see ‘frame rate’, ‘persistence of vision’), and the Liquavista displays promise to deliver this.

According to Intomobile, Samsung anounced their purchase last Friday. It is unknown what the electronics giant paid.

Liquavista is a product of the Philips’ High Tech Campus, formerly known as Natlab, in Eindhoven.

E-voting sceptic Rop Gonggrijp detained in India

Filed under: Technology by Branko Collin @ 7:04 pm

On December 12 Dutch hacker Rop Gonggrijp and his colleague Alex Halderman from the USA were held for twelve hours Delhi airport, the former writes on his blog.

Gonggrijp suspects this may have to do with the Indian Election Committee’s investigation into his and others’ involvement in a “conspiracy to destabilize India“, i.e. proving that India’s voting machines can easily be hacked for vote rigging.

According to Indian authorities, Gonggrijp was held because he should not have been issued a visa. Since he had one anyway, they decided to let him into the country after all.

The Netherlands abandoned voting machines for national elections in 2007 after Gonggrijp demonstrated that it is trivially easy to hack them.
