Tradeable loot boxes declared illegal in the Netherlands

Filed under: Gaming by Branko Collin @ 1:55 pm

toy-cars-branko-collinIn a study released last week, The Netherlands Gaming Authority (NGA) has concluded that some video games are breaking the law by offering so-called loot boxes.

Loot boxes are in-game purchases in which the buyer does not know what is in the box until after the purchase. A box can contain in-game items such as cosmetic changes to one’s avatar, as well as items that make playing easier.

The NGA uses two factors to decide the legality of loot boxes. If chance determines the contents of a loot box and if loot boxes can be traded outside the game environment, the loot box is in violation of Dutch gambling laws. The NGA is giving manufacturers the opportunity to improve their loot box systems. From 20 June 2018 onwards, the authority will start taking measures against non-compliant manufacturers.

According to NOS, four games from NGA’s study that contain transferable loot boxes are Fifa18, Dota2, PubG and Rocket League.

Earlier this month South Korea’s Fair Trade Commission fined four local video game companies for allegedly deceptive loot box promotions, The Korea Herald writes.

Flying a hydrofoil boat is like riding a bike

Filed under: Bicycles,Sustainability,Technology by Branko Collin @ 12:10 am

solar-boat-delft-gbvm2

Controlling a single-track hydrofoil is like controlling a bicycle, two Masters student from Delft University claim in a paper published in Naval Engineers Journal last month.

“We used a mathematical model to validate whether a single-track hydrofoil using two foils, one behind the other in the water, would remain stable in the same way as we stay upright on a bike,” one of the students, Gijsbert van Marrewijk, told Delft University last week. The principle of staying upright on a bike is the one of steering into the fall.

Van Marrewijk and his co-author Johan Schonebaum were inspired by the hydrofoil boat of the Solar Boat team of their university, of which they were members. Hydrofoil boats have wings under the hull that lift the boat out of the water, reducing drag and, all other things being equal, increasing speed. Using a single-track hydrofoil reduces drag even further over the more conventional and more stable multi-track vehicle.

See the 2015 version of the Delft University Solar Boat team in action:

For some reason recent versions of the boat have returned to multi-track hydrofoils. The mathematical model developed by the two students should make it easier to test new designs in a computer simulation.

‘We want more women in municipal councils’, say Dutch voters, but political parties disagree

Filed under: General by Branko Collin @ 2:40 pm

billboard-branko-collinPreferential voting in last month’s municipal elections in the Netherlands has caused a drastic increase of female representatives, newspaper Trouw reported two weeks ago.

The campaign Stem op een Vrouw (vote for a woman) encouraged citizens to vote tactically by voting for a woman the polls suggested would just miss out on being elected. The result was an increase of 20% women in the Dutch municipal councils.

Municipal councils in the Netherlands are elected once every four years. A council sets the policy for its municipality and supervises the municipality’s executive board. A party receives its portion of the available seats based on the percentage of votes they win. The council seats are distributed among the candidates that make up the top of the party list, but if a lower ranked candidate gets a lot of votes, they bump the lowest candidate of the primary selection from her or, as the case may be, his seat.

In the previous four years, a record-breaking 28% of council members were women, but this year the new record was set at 34%. Citizens gave women a preferential vote across all party lines, although the effect was most noticeable for candidates of D66 (Democrats), Groen Links (Greens) and SP (Socialists).

Most resistant to the idea of female council members turned out to be the political parties and the candidates themselves. In 334 of the 335 municipalities, men dominated the party list, NOS reported in March. In the one town where there was an equal amount of male and female candidates, Heemstede, the male party leaders still outnumbered the female party leaders 2:1.

Both PvdA (Labour) and SP had their candidates sign a waiver, stating they would give up their seat if they got in on preferential votes. Several female Socialists gave up their council seats. The waiver has no legal force according to John Bijl of the Perikles institute: “You swear loyalty to the law and the constitution, not to your political party.” In Woerden, local party Inwonersbelangen (Citizens’ Interests) threw Lia Arentshorst out of the party after she refused to give up her seat.

The campaign Vote for a Woman was founded by Devika Partiman after a campaign with the same name from the 1990s in Surinam. The campaign also ran during the previous parliamentary elections, where the effect was more subdued, presumably due to the fact that the representation of women in parliament has historically been greater already.

Commodore 64 chiptune based on Skype ringtone

Filed under: Music,Technology by Branko Collin @ 12:09 am

Helmond based, legendary 1980s home computer composer Jeroen Tel teamed up with LMan (Markus Klein) in February to enter CSDK’s “$11” Commodore 64 chiptune competition.

jeroen-tel-staffan-vilcansThe code $11 does not refer to a dollar amount, but to the value used for selection of the waveform; composers were only allowed to use a triangle wave for this contest.

Tel and Klein elected to take the famous Skype ringtone as the basis for a 2 minutes and 39 seconds long song called Skypeople.

They entered a second song called $11 Heaven, notable for the absence of arpeggios, a type of chord extensively used in the heyday of home computers when these devices lacked sophisticated sound chips that would have allowed for the playing of polyphonic chords. At least the Commodore 64 with its advanced SID sound chip allowed for three notes to be played at once.

Skypeople and $11 Heaven netted the two composers the 1st and 3rd prize respectively.

When Bijlmer was the city of the future

Filed under: Architecture by Branko Collin @ 2:00 am

bijlmermeer-anefo-joost-eversThese days, lively cities that don’t shut down after closing hours are the dream, but in the 1930s, the opposite was true. Architects were looking for ways to separate out the places where people work, live and play. The war threw a spanner in the works of their plans, but in the 1960s, the building of a new town near Amsterdam was started that would be linear, clean and uncluttered: Bijlmermeer.

This new town would be dominated by high-rises laid out in an iconic honeycomb pattern around parks.

The 99% Invisible podcast explores in two episodes how this worked out (episode one, episode two). If you don’t like audio, the accompanying articles are extensive. But if even that proves too much, here is the TL/DR (spoiler alert!):

In 1943, the Swiss architect Charles-Édouard Jeanneret (better known as Le Corbusier) published a book called Charte d’Athènes (The Athens Charter). It outlined exactly how to build new cities in the way the architects from CIAM had talked about back in 1933.

Many cities took some of the ideas and left others. But the city planners of Amsterdam wanted to go further. They decided to build a new neighbourhood, close to Amsterdam, that would be a CIAM blueprint — a perfect encapsulation of Modernist principles. It was called the Bijlmermeer, and it tested these ideas on a grand scale. When it was over, no one would ever try it again.

Bijlmermeer had trouble getting off the ground. Work on the sub-way line to Bijlmermeer was delayed and the tenants living in the roomy flats had to drive over a dirt road to get anywhere. And they did have places to go, because stores would not arrive until 1975. Disillusioned prospective tenants decided to stay away and a lot of the apartments remained vacant. This made the town a dumping ground for those that society did not want around, notably immigrants from Surinam, Turkey and Morocco, and gays. The empty apartments also provided an ideal place for criminals to hang out, and the area became a canvas for their work.

The lofty architectural ideals often clashed with the cold reality of how cities work. Flats were laid out egalitarian, they all looked the same and nobody got a better apartment than anyone else. Roads were elevated so that pedestrians and cyclists did not need to mingle with murderous car traffic. This had the unfortunate side-effect that motorists had no-one to ask the way, and since all the buildings looked the same, having people around to ask the way was useful.

Ten years into its birth, Bijlmer (short for Bijlmermeer) was turning into a ghetto. Crime was on the rise and the neighbourhood (the town had become part of Amsterdam) started to become part of the way the Dutch dealt with and talked about race.

The hammer blow to Bijlmer as the city of the future was dealt on Sunday 4 October 1992, at 18:35 in the evening. An Israeli airplane crashed into the Groeneveen and Klein-Kruitberg tower blocks, killing 43 people and wounding 26. The city decided to tear down most of the high-rises and replace them by smaller apartment buildings or houses. Amsterdam had learned its lesson.

Or so it seemed. In 2017 the city government decided a new neighbourhood full of high-rises and constructed according to the latest architectural principles is to be built on the edge of the city, Sluisbuurt.

Groningen Rhapsody, protest song about earthquakes by Maartje & Kine

Filed under: Music,Nature,Sustainability by Branko Collin @ 4:37 pm

The ninth largest gas field in the world is located under the Dutch province of Groningen and extensive exploitation has led to an instability of the ground. In 2015 local comedy duo Maartje & Kine wrote this parody of a famous rhapsody in which they lament the troubles the region has seen.

groningen-rhapsody-maartje-kineThe lyrics are in Dutch, but you could try your luck with YouTube’s automated translation. Here are some quotes to get you going.

“Open your eyes, look at your barn and see… [a crack].”
“Our cows only produce milkshake these days.”
“He is the minister, evil and sinister.”

Last month, Groningen was hit by a gas exploitation induced earthquake that registered 3.4 on the Richter scale. It was the strongest quake in Groningen since 2012 and the fifth quake that month. As a result, 3,000 citizens filed insurance claims, on top of the 100,000 claims made earlier.

Branko’s favourite stories of 2017

Filed under: General by Branko Collin @ 7:24 pm

fireworks-branko-collinOn the dying hours of the year, I present you with my favourite postings of 2017. If you only read this in the next year, I hope you are washing away your last traditional oliebol with a mug of strong coffee.

In 2017, parents wanted their children to be born in the ‘right’ hospital, not because of the care they would receive, but because of the birth certificate; it had to list the proper city. As if the birth place of your child were some cool brand.

A bicycle bridge was 3D printed and installed in Gemert. Plastic tchotchkes resembling Delftware miniature houses managed to sell enough at 50 euro a piece to make an overpriced kickstarter succeed.

Cool teacher Matthijs Jansen has been busy inventing gym class games to keep his students happy. The kids seem to appreciate the effort, with one girl saying he is the coolest ‘meester’ (male teacher) of the school. “To be fair”, she added, “he is the only meester we have.”

The world-famous bike path underneath the even more famous Rijksmuseum in Amsterdam has been making the Dutch capital a lot of money. The city has fined 27,000 moped owners 90 euro each for illegally using the path. If you need to go from the city center to the South of Amsterdam or vice versa, that bike path is often the fastest route.

Other stories from 2017 that drew my eye were:

Finally a ton of casual sexism portrayed the Netherlands in a bad light (here, here, here and here), and to top this off, the top 15 richest Dutch artists are all men.

Do not break our trains, please — a visit to the Dutch Rail workshop in Amsterdam

Filed under: Technology by Branko Collin @ 2:08 pm

The Amsterdam onderhoudsbedrijf Watergraafsmeer, the workshop of Dutch Rail in Amsterdam and one of a few dozen in the country, opened its doors to the general public yesterday.

The workshop is part of a large classification yard in the east of Amsterdam and can be tricky to reach, which is why Dutch Rail had borrowed the Mat ’54 (a hondekop, dog’s head) electric train from Stichting Hondekop to shuttle visitors between Central Station and the yard.

The Mat ’54s were in service between 1956 and the mid-1990s. They were replaced by the very similar looking Mat ’64, which lacked the distinctive ‘dog’s head’ (introduced to better protect the driver) and which were used into the 2000s.

Also on display were a German ICE high speed train, a postal train, several regular trains that may or may not be in service still (sorry for the dearth of details, I am not a train geek) and Dutch Rail’s executive train, De Kameel (The Camel).

nedtrain17-02-kameel-brankocollin

The latter’s official designation is NS20. Only one was ever built, in 1954 by Rotterdam train builder Allan. It was scrapped for spare parts in 1991, but brought back in 2008. The train consists of two rooms with a clear view of the tracks front and back, a toilet and a kitchenette, with dual cabs built in the roof.

nedtrain17-03-kameel-coupe-brankocollin

nedtrain17-04-kameel-cockpit-brankocollin

The whole event, mostly taking place in what Nedtrain claims is the largest plastic building in Europe, was a rather charming affair with engineers still working (behind barricade tape) on trains, necessitating house rules such as “leave our tools alone”, “never stick your fingers in machines” and “please leave our trains the way you found them”.

nedtrain17-05-brakes-brankocollin

Scrapped train parts such as signs and emergency brakes, familiar to anyone who has commuted on Dutch trains, were sold for 20 euro each, the proceeds going to a good cause.

What happened to the Superbus?

Filed under: Automobiles,Sustainability,Technology by Branko Collin @ 5:05 pm

superbus-jan-oosterhuis

It was a crazy idea that might just work—the Superbus, a cross between a Formula One car and good old public transport.

The Superbus was one of the many sustainable inventions that Delft technology professor and former astronaut Wubbo Ockels either came up with or helped develop. It would have comfortably carried 23 passengers in bucket seats on a custom built road between Amsterdam and Groningen, cutting current travel times to shreds.

But even before Ockels’ death in 2014 the Superbus had disappeared off of the world’s radar. It’s website is still up, but hasn’t been updated since 2012, with the exception of an obituary for Ockels. And where did the actual prototype go? Dagblad van het Noorden decided to find out last June.

The prototype is currently stored in a warehouse at the University of Delft, where it was developed. A spokesperson for the university told the paper: “The bus is still in a good condition, although it can no longer be driven. We had to remove the batteries for safety reasons, for example.”

Ockels’ widow Joos told the paper that it would take several months to get the bus roadworthy again. She receives regular calls from people and organisations that want to rent the vehicle for a trip.

The bus’ license plate expired in 2014.

Several organisations have expressed interest for exhibiting the Superbus. The Transport Museum in Lelystad however has to first overcome the obstacle of not yet existing, and a plan to store it in a facility of Stichting Wadduurzaam (presumably so that it could be displayed to the public) failed because the storage space would have to be fixed first, which would be too costly.
