Films seen in August 2010

During the summer vacation I’ve seen the following films in August:

Once a popular genre a few decades ago, the Western genre hasn’t seen much activity in the film industry lately. I’m talking about the ‘authentic’ western films taking place in the 19th century, not the comedy, horror or contemporary westerns which have been popular with the film industry recently. 3:10 to Yuma is one of those films which fits in the former category, and it’s refreshing to see a modern western which has quality. Russell Crow and Christian Bale shine as the stars in this film. I loved it, but I disliked seeing the silly, incredible ending. I’d still recommend it though. Considering the scarcity of ‘authentic’ westerns films with quality in this decade, I’m looking forward to see two more westerns which were produced in this decade: The Assassination of Jesse James by the Coward Robert Ford (2007) and The Proposition (2005). Wikipedia has a list of all of them, but most do not fall in the ‘authentic’ category, even though they’re good films, such as Brokeback Mountain.

Before the Devil Knows You’re Dead is a brilliant crime drama. Two brothers decide to rob a jewelry store, but due to coincidence their plan goes wrong. The rest of the film then depicts the increasing desperation of the brothers as the net tightens around them. I noticed this is one of the movies where they try to suppress the noise of a firearm with a pillow, I expected this to be another invention of Hollywood, but apparently it does have some effect in reducing noise.

Che is a biographical film about Che Guevara. If you’d judge the film by it’s length, you’d have to say you certainly get great value for money because you get both part 1 and 2 which contain over four hours of film. Before I watched this movie I had a negative view on Che as an ‘evil’ revolutionary socialist who helped to instate the current dictatorial regime in Cuba, but after seeing it I can empathize with him more. The truth is that Fulgencio Batista was more loathsome than the socialists who had overthrown him and had more consideration for the interest of the Cuban people. However, according to the criticism mentioned in the Wikipedia article we should be careful not to sympathize with Che too much.

Happy-Go-Lucky is a comedy-drama film. I had no idea how they made up the film’s title, but after looking the word up in a dictionary, I learned that happy-go-lucky is a term for a person who is ‘blithely unconcerned, carefree’. In that case the term is very appropriate for the title of this film. The protagonist of the film, Poppy, is exactly that, carefree. Her driving instructor is her polar opposite. During the film Poppy comes in contact with the negativity and suffering of the harsh real world. She learns to understand and live with the real world in the end, fortunately without losing the healthy dose of optimism. Normally I’m not into comedies, but this film is a hybrid between drama and comedy, and a bit slower paced as well. It had me laughing, but some other persons who usually appreciate comedy could not appreciate this film.

Slumdog Millionaire is an archetypal Romeo and Juliet story set in India, a truly enchanting film. From my perspective this was a great film, but for others this film ruffled some feathers. The criticism is that the film contains a great deal of stereotypes about India, which I agree with. If a foreigner made a film about a boy growing up in the Netherlands which featured (negative) portrayals of prostitution, drugs, same-sex marriage, clogs, windmills, the Party for Freedom all blended together and filled with stereotypes I’d feel my nation is being ridiculed, too. What offends me most however is the idea that Jamal becoming a millionaire is supposed to be destiny. As noted elsewhere, are the rest of the inhabitants of the slums destined to live in poverty then? Destiny is disgusting, let’s just call it good luck.

On another note, I watched The Mummy: Tomb of the Dragon Emperor on tv. This is the best example of a film which relies solely on spectacle and special effects for success, because the film is lacking in all other departments. Nevertheless, it was fun to see. Jet Li is totally cool. Throw in all kinds of exaggerated elements in the story like the Terracotta Army, Yeti’s and make up that the super evil emperor built the Great Wall of China over the corpses of defeated soldiers so you have an excuse for a huge battle at the end. Fortunately all the spectacle eclipses the other aspects of the film, so you will continue watching despite being annoyed by the stupid script.

TV-series wise, RTL was so nice to start broadcasting the final season of 24 recently. Again they show two episodes on sunday evening, but this time at a later timeslot, so the last episode ends past 12 o’ clock PM. Like most people I need to get up early in the morning, so now I have to resort to the VCR. Again they’re broadcasting this long after the season finished in the USA and they’re forcing me to use my VCR, thus downgrading the quality. They still didn’t learn and make it tempting to resort to downloading the whole season over the Internet once again.

Visited the GUADEC in the Hague

Last Wednesday I visited the GUADEC (GNOME Users and Developers European Conference), a yearly conference for developers and users of the GNOME desktop environment. The GNOME organisation is very international and usually they communicate over the Internet, but once a year they can meet each other in person at the GUADEC. I had never visited the conference before, because it is held all over the place in Europe, most of the time at places too expensive for me to travel to. This year it was held in the Netherlands, in The Hague. Even though I’m more interested in KDE (the alternative to GNOME) nowadays, I certainly wanted to use the opportunity to visit a free software conference which was close by.

Entrance was free, but I made a small donation. I decided to visit for only one day, because I deemed train tickets (€ 14,20 for a return ticket for one day, with 40% student discount) to be too expensive, and because I had other work to do. In fact I’m still tying a few loose ends together for work on a course I followed during the last block of the academic year, because of procrastination. As is customary for these kind of conferences, you download video recordings of the talks later, so no worries if you miss it. GUADEC 2010 was held from July 26th to July 30th, with the talks scheduled on 28th (Wednesday) until the 30th. Kudos to the team organizing GUADEC 2010, because I have the impression it must have taken a ridiculous amount of effort.

I followed the following talks on Wednesday (program can be found here):

  1. Keynote
  2. GNOME, the web, and Freedom
  3. Evolution – Got the wheels to race, the wings to fly, what next?
  4. State of the GNOME 3 Shell
  5. GPLv3: Better Copyleft for Developers and Users
  6. GNOME: State of the Union
  7. Building a strong post-3.0 GNOME story

In the second talk Luis Villa made a case for incorporating the web more in GNOME. I agree with his observation that not the Linux desktop but the web has ‘won’ or become mainstream. A few general examples of features already present were given of how this could be achieved, such as uploading photos to online services via photo management applications and allowing languages used for web design to be used for developing applications in GNOME (such as Seed). Louis argued this can be taken further. I don’t know however what more can be done, and neither did Louis, his talk served to inspire brainstorming on this subject.

The next talk on Evolution was far more technical, aimed more at developers, but very interesting nonetheless for me because I could understand most of it. Evolution is an application which I almost use daily for my e-mail, and it was interesting to hear what the plans for the future are.

Then the talk on GNOME Shell. I haven’t tried it yet, and I’m not fully convinced this will improve my productivity. To be honest this might be because the talk couldn’t capture my attention very well, so I still do not understand exactly what GNOME Shell is and why it will be an improvement, it was not as interesting as the other talks. I’m certainly curious to see how it will work though when it’s ready for end users next March.

The following talk on the changes between version two and three of the GPL was the best talk I attended. Bradley M. Kuhn is an excellent presenter, who managed to keep me interested at every moment of his talk. His analogy of licenses and software was good; licenses have bugs just like software, and version three of the GPL was necessary to fix some errors and loopholes in version two. Licenses are something very technical and are possibly difficult to understand, but Kuhn managed to explain it perfectly to those who never studied law.

The GNOME: State of the Union talk is possibly one of the funniest presentations I’ve ever witnessed. Fernando Herrera and Xan Lopez parodied issues concerning codes of conduct in an excellent way. I had the impression that GNOME was lacking progress compared to KDE, and this talk changed my mind. Quite a few things have been achieved already on the road to GNOME 3.0, but I still have a preference for KDE though.

I wasn’t paying attention at the last talk on the future after GNOME 3.0, because I couldn’t keep my eyes open. I had to leave home early to catch my train and hadn’t had much sleep the night before, I guess I was too excited for GUADEC. So after this talk I decided to head home. I received an invitation to join the Canonical party in the evening, but decided against this because I don’t know the people in the GNOME and Ubuntu community well, and had to use a train to get home.

I went to the conference alone, because I didn’t know any friends who where interested and going as well. When I arrived, I did recognise some of the names of the Dutch GNOME community and the persons giving the talks, but I only know them superficially through reading about their work via Planet GNOME. I was pleasantly surprised though to see two people from the Dutch KDE community attending as well, whom I had met at a KDE 4.4 release party a few months ago. It was nice talking to them again. One of them, Tom Albers, has also blogged about GUADEC.

I know it’s a conference for geeks, but you can overdo it. I noticed quite a few people who were more interested in staring at their notebooks than they were in listening to the speakers. Do you really need to inform everyone through a microblogging service like Twitter and Identi.ca that talk X is going to start now and other trivialities? And like a good free software citizen, if you must then please use Identi.ca instead of Twitter. Anyway, I enjoyed visiting GUADEC 2010, and hope Akademy will also be held in the Netherlands in the future.

Vacation in the USA’s west, the experience

One of the first things we noted when we arrived in the USA is the amount of gas guzzlers on the roads, starting with our own car which did 16,1 mpg (14,6 l/100km, or over three times the amount of a Toyota Prius). Sports cars like the Ford Mustang for example seem to be almost a commodity and you see a lot of SUV’s. Of course cars like those would be taxed to death in the Netherlands. Which I think is a good thing, because I live in close proximity to a highway. You see a lot of cars which are not available on the European market, and while in the Netherlands French and German cars are most popular, in the USA you see a lot of Japanese and American cars. In the USA cars cost a lot less as well, for example a Nissan 370Z starts at $30.410 (€ 23.521) while it starts at € 55.100 ($71.239) in the Netherlands. I wish some cars, like the Chevrolet HHR with it’s distinctive design, which appear only on the American market would be sold in Europe as well. Also of note are the customised license plates. While listening to the radio during trips with the car, you often hear commercials with voices speaking very fast, as if they desperately would want to save money by reducing the length of the commercial. Amusing.

I really appreciated that almost all hotels offer WiFi free of charge. Being able to use Google Maps gives you a good tool to look for restaurants in the vicinity of your hotel. We definitely would have missed some great restaurants if I wouldn’t have been able to use Google Maps. Concerning food, some hotels featured elaborate breakfast buffets, either included or for an extra charge, and some other hotels were a serious disappointment in that regard. I’m going to name and shame an example here, the Alpenhof Lodge in Mammoth Lakes. Decent hotel with a nice swimming pool, and breakfast was included. However, the breakfast turned out to be some doughnuts and muffins placed near the entrance of the hotel, they didn’t even serve bread. The hotels which did a good job served tasty breakfast. I liked baked/boiled egg and bacon, muffins and doughnuts were okay, baking your own waffles with a waffle iron was fun. Dutch stroopwafels win over American waffles though!

One thing we noticed in restaurants is that in some restaurants a gratuity is optional, at the discretion of the customer. In other restaurants, they include a gratuity of 15% or so on the bill! Wikipedia is my best friend here, telling me that a gratuity added by the restaurant without customer input, the so called autograt, is not unheard of in certain situations in the USA. The most common reason would be if a large group was served; we always were with five persons however. Even so, I think it’s odd you would charge extra if you had a large group of customers in your restaurant? More customers means more revenue, if I were a restaurant owner I certainly wouldn’t ‘punish’ them with an autograt and be grateful for more customers. It is uncommon for restaurants to place an autograt on every customer’s bill by default, and considered dishonest according to Wikipedia. I also read there that it’s considered normal to inform customers of an autograt in advance, but this was not the case in the restaurants we visited. Fortunately, and as I expected, customers have the right to refuse giving an autograt, even if they were informed of the autograt in advance. In the Netherlands this practice would probably be considered outrageous, gratuities are expected here but at the customer’s discretion. I voiced my opposition to giving in, but my father didn’t object and paid these autograts. It’s his money and he should do with it as he pleases, but I certainly would have flat out refused to pay an autograt. In the end, restaurants which were okay and charged an autograt received more gratuity than the restaurants we thought were above average and didn’t charge an autograt. There is a very suitable idiom for that in my language, ‘de brutalen hebben de halve wereld’. In other words, if you’re cheeky you receive more than you should. Funny to read in the Wikipedia article by the way that in some Asian countries tipping is not part of the culture at all, and could possibly even offend those receive it.

The air conditioning was often used unnecessary in many places in my opinion. For example in Bryce Canyon City it was turned on at breakfast and it was too cold, while the temperatures outside even in the afternoon were not too warm at all. Most of the time it was unnecessary during the night in the hotel rooms, but my family insisted on turning it on. Our own house doesn’t have air conditioning at all, even though we do have the occasional heat wave in a summer in the Netherlands. The only places where I appreciated air conditioning were Phoenix and other places with very high temperatures. It takes a few years to get accustomed to the heat in those places if you’re new we were told by hotel personnel, and another local told us you can sleep without air conditioning in Phoenix. Another aspect of environmental unfriendliness of my family were the frequent instances of buying bottled water, because ‘the tap water contained too much chlorine, which could make you sick’. Yes, the tap water in the USA didn’t taste very well, but buying bottled water is ridiculous and wasteful.

I’m careful not to generalise, but I the Americans we met were on average quite friendly. For example when we stopped in Zion National Park and met the snake there, two cars passed us in what was the middle of nowhere, and both of them stopped. The man in the first car noticed we were taking photos, so he offered to take our photo so all the five of us could be photographed. We accepted. The man in the second car stopped to ask us if we had any problems, if our car had broken down or something. I wouldn’t have seen that happening in the Netherlands. And I don’t think I’ve ever seen so much people who were obese, especially the amount of people I’ve seen which are morbidly obese is staggering. Not surprisingly, obesity rates in the USA are among the highest in the world.

I enjoyed this vacation, but if I hadn’t come along I wouldn’t have missed it, except for the Getty Villa. I enjoyed seeing so much, but I do not think it was worth all the long flights with their lack of leg space, the vying for space on the armrests, the car trips, and tiresome hotel switching. I do not think there is much added value to seeing things like the Grand Canyon, Death Valley with your own eyes while you are physically there. Most nature documentaries offer you a better view of those places, with cameras revealing what you can’t see if you only walk for a few miles across the southern rim of the Grand Canyon. If you search for ‘bryce canyon’ on Flickr you get 171.243 results, including impressions of the landscape in the winter, which I didn’t see with my own eyes. I’d rather take a look at what Flickr has to offer than go there myself so I can save a lot of time, effort and money. The sort of vacation I like best are intra-European city trips. Flights are short, or you can take the train, you don’t need 18 days and it’s more friendly to your budget. And with five people you’ve got to take account of a lot of different wishes, which makes planning more inflexible.

One more thing, the usage of the U.S. customary system instead of the metric system was very annoying for me as an inhabitant of the Netherlands. You constantly have to convert measurements made in units like gallons, miles, feet and Fahrenheit. Americans should be very proud that they, along with Burma and Liberia, have not yet officially adopted the metric system unlike the rest of the world. The U.S.A. should join the rest of the world and start the process of metrication instead of miring itself in backwardness.

Vacation in the USA’s west, diary with photos

Last Monday on 19 July I returned from a holiday in the USA’s west. We departed for the USA on the 1st of July, on a holiday paid for by my parents, probably the last one including my parents, brother and sister. This first post will contain a diary and photos of the vacation, a second post will follow with more general observations on the USA and my experience of the vacation. The plan for this vacation consisting of eighteen days was to ride through the states of Arizona, Utah, Nevada and California by car, stopping for the night at hotels and eating dinner at a restaurant for every day. I have mentioned the restaurants we thought were notable.

Day 1: Stranded at Washington Dulles airport

A delay at Amsterdam Schiphol airport caused us to miss our connection to Phoenix at Washington Dulles airport, Northwest Airlines provided us with rooms in a hotel near the airport. Even though they foresaw that there were passengers who would miss their connecting flights at Washington Dulles airport, they didn’t give those passengers priority for the immigration officers. It was a close call, and the waiting line for the immigration officers cost us just a few minutes too much time, making us miss the next flight.

Day 2: Arrival in Phoenix

We rose early this day at 3:00 so we wouldn’t miss our flight to Denver (Colorado) where we would transfer to a flight heading for Phoenix. The climate of Phoenix is very hot with temperatures near 45 ℃, walking around for the first time and feeling the breeze outside is like experiencing the hot air of an oven rising to your face after you open it. Fortunately temperatures would be more comfortable when we left Phoenix, until we arrived in Las Vegas. The next stop was at the car rental company, Hertz, where we would pick up our car we would use for the rest of the vacation, a Toyota Sienna. Even though we’d already arrived a day late, we were told a car wasn’t available right now and that we had to wait for a bit until one was ready. My parents complained, and got upgraded to a Nissan Armada for no extra charge. It’s a beast with its 360 hp, 5,6 L V8 engine. Unfortunately neither my brother nor I could drive because that would require extra costs. Not sure what the reason was again, if I recall correctly the reason was that we were under 25 years of age. The first stop was at a Walmart, which amazed us because of its huge size. Even in Dutch large cities supermarkets aren’t so large, maybe 1/4th or 1/3rd the size of a Walmart store. We had to skip a part of our journey to make up for the lost time, we headed to Tusayan and on the way we visited Montezuma Castle.

Day 3: Grand Canyon

On this day we walked for a few miles along the southern rim of the Grand Canyon. Interesting were the different types of stone displayed along the route, with accompanying explanations listing their age in millions of years, running in the three digits. The Grand Canyon is indeed a great view, with it being so huge. The rest of the day was spent driving to the next stop in Bryce Canyon City, stopping for a few times for other lookout points along Grand Canyon and Red Canyon in Utah.

Grand Canyon

Day 4: Bryce Canyon

I’m glad we went to see Bryce Canyon after Grand Canyon, because the latter displays more beauty than the former. Especially notable are the hoodoo’s, works of art created by erosion. The fact that I shot most of my photos here says a lot. Our next hotel was located in Cedar City. Most restaurant were closed down because it was Sunday, so we ate at a fast food chain we don’t know in the Netherlands, Taco Bell. They serve Mexican fast food, which was almost universally hated by us. Not to say that we didn’t like Mexican cuisine at all, but besides Taco Bell the Mexican restaurant we chose earlier was mediocre, unfortunately we didn’t choose to eat at another better Mexican restaurant later. Could anyone identify what species of lizard is on the first photo?

Hoodoos in Bryce Canyon

Day 5: Las Vegas

The next day we would visit Zion National Park along the way to Las Vegas. After missing some exits on the highway, which resulted from the absence of a built-in satellite navigation system in our car, my parent’s refusal to buy a separate satellite navigation system on my recommendation and inadequate signposts along the roads in the USA in general. And this wasn’t the first nor the last moment we would lose track of the route. The funny thing is that we later met other Dutch people who told my parents buying satellite navigation had been a good decision for them. At a stop we figured out we needed a permit to take a walk in the park (at that specific spot at least) and decided to drive some further distance into the park. When we had seen enough we decided to turn around and stop to enjoy the view before continuing the journey. After taking some photos, I discovered a snake had crept up to one of the front wheels of our car. It was quite large, and not aggressive. Fortunately we could move the car without flattening it, and the snake retreated into the grass when it could apparently no longer enjoy the car’s shadow. Hopefully someone can tell me what snake it is? I don’t want to spend much words on Las Vegas. It’s the most decadent, crowded, vulgar and fake city I’ve ever seen. The only positive points I can mention are the Indian restaurant we stumbled on by change at the Strip, the taxi driver with a good sense of humour. The most memorable phrase heard was definitely ‘water one dollar’.

Snake in Zion National Park

Day 6: Death Valley

During the night I was woken up a few times because of my brother had to vomit. My sister hadn’t been feeling well since a few days before that. I doubt it was food poisoning, because I and my parents had no problems. This day we would drive through Death Valley and end the journey in Lone Pine. We stopped at Zabriskie Point in Death Valley, then we started driving again. Temperatures were probably around 45 ℃ at Zabriskie Point, so it was hot but nothing new after we had experienced Phoenix. After arriving in Lone Pine, we ate in a Chinese restaurant which ranks as one of the best restaurants of the entire vacation.

Day 7: Mammoth Lakes

Mammoth Lakes is situated on a higher elevation (2,4 km, while Death Valley was below sea level). In the winter it’s a ski resort, quite a difference between this and Death Valley yesterday. We followed some of the hiking routes in the area. It was strange to see snow still lying around at some places, while the temperatures were probably hovering above 20 ℃.

Day 8: Yosemite National Park

On this day we visited Yosemite National Park. The view over the Yosemite Valley was magnificent. Bridalveil Fall was good. I like waterfalls, except for the water vapor covering the lens of my camera. When we drove further down the valley we were dismayed to discover that it was infested with tourists and campings. The hotel near the valley was the first one I encountered to charge a fee for WiFi, in all other hotels it was free of charge. As you can see on the photos, we received a replacement for our car which had broken down. That was remarkably quick service for such a relatively remote place.

Day 9: Yosemite National Park

If almost everyone who has visited the eastern coast of the USA talks about seeing the giant sequoia, and you have seen them on TV but not with your own eyes, you can’t allow yourself to miss them. After a lengthy trip – someone thought that the apex of the tourist season was a good time to start road maintenance – we arrived at Mariposa Grove. The sequoias there aren’t the oldest or the largest, but they were impressive nevertheless. We noticed there had been fires in the forest recently, but these were allowed to go on. Apparently forest fires are good for the health of forests. We ended the trip in Sonora.

Mariposa Grove

Day 10: San Francisco

While I felt uncomfortable with the high temperatures in places on lower elevations in California and Arizona, San Franciso makes me complain because of the low temperatures in July, the frequent cloud cover and fog but most of all the strong winds. Check up the Wikipedia article on SF to learn about the specifics of it’s climate. My first thought is that it’s a nasty climate, even though the average lowest temperature is 8 ℃ in January, I wouldn’t want to live in SF instead of the Netherlands. I’d rather have a winter and a real summer than neither like in SF. After we arrived at the hotel and were charged an arm and a leg for parking the car at the hotel ($30 a day), we went to Fisherman’s Warf. After trials and tribulations with the public transport system in SF, partially because of the lack of preparation on the part of my parents, and partly because public transport doesn’t seem to be well organized and easy to understand in SF, we arrived at Pier 39. I experienced a dejá vu here, since Pier 39 is a hornet’s nest full of tourists just like Las Vegas, and because there’s nothing interesting to see there.

Day 11: San Francisco

This day started with splitting up, I visited the Asian Art Museum, while the rest of my family watched Spain defeat the Netherlands in the FIFA 2010 World Cup final. To the square just west of the museum, in the Civic Center, two large screen displays were set up for fans who wanted to watch the world cup. There were surprisingly much Dutch people around, which I also noticed in our hotel. It’s almost like Dutch people attract each other in foreign countries, like we are contagious, or we’re just a very adventurous people who love to travel. Even more surprising was that my brother and sister got sunburned in SF of all places, the city which is so frequently covered by clouds. Apparently there was more sunshine than I noticed. They told me they forgot to use a sunscreen, but given the tan my sister developed after all those hours of lying under the sun, I expected they wouldn’t get burned even without it. Anyway, the jade artwork on display in the museum was totally awesome, I can heartily recommend the museum. In the afternoon we boarded the Duck Tour, a tour of over the streets and the water of northern SF with an amphibious vehicle. We had a very good guide, she told us they had very few customers since the recession. In the evening we went to Thai restaurant which was just two blocks away from our hotel. The various Chinese and Thai restaurants we visited during this vacation certainly inspired me to try these cuisines at home. The only gripe I and my family members have, especially with the Thai cuisine, is that dishes are far more spicy or hot than in Indian or Chinese cuisine. Even the dishes which rated as moderately spicy make you spit fire. I should be careful not to generalize here because those cuisines can be extremely hot too, but on average most Thai dishes seem to win.

Day 12: Monterey

We visited a lookout point near the Golden Gate Bridge, and then followed the Pacific Coast Highway south to Monterey. There was much more I had wished to see in SF and especially the SF Bay Area, such as the Rosicrucian Egyptian Museum, the Intel Museum and Silicon Valley, but unfortunately there was no time for that. In Monterey we visited the Monterey Bay Aquarium there, which I can recommend. I never expected that tuna, the fish which frequently ends up on my pizza’s, would be so large.

Day 13: Ventura

When we continued driving south this day to Ventura, we stopped on a lookout point over a beach near the sea, where we saw elephant seals. In southern California the climate was much more palatable. The sea water was a bit cold, but after acclimatizing for bit it was acceptable for swimming. By chance we happened to discover a very good Italian restaurant.

Elephant seals

Day 14: Los Angeles

On the way to Los Angeles we would pass the Getty Villa, so we split up there when I was dropped off at the museum and the rest of my family went to the beach. The Getty Villa was the best thing I have seen during this vacation. It’s not the the ancient Greek, Roman and Etrurian artefacts exhibited in the museum which are remarkable, it is the museum itself. It’s modelled after a real Roman villa, the Villa of the Papyri from southern Italy, and many other Roman villas. Descriptions in the museum explain in detail the features of the villa, and which real Roman villas served as inspiration for them. I did notice some strange things though. Most obvious are of course the fountains, for example seen in the photo of main courtyard in the Wikipedia article of the Getty Villa. Why were these fountains placed there when there was such a great desire to recreate an authentic Roman villa? I also noticed wall paintings of columns on the inner sides of the walls surrounding the main courtyard. It seemed to me like they ran out of cash when they wanted to decorate the walls with real pilasters and instead chose to paint columns. Or are painted columns authentic as well? Also, I wonder how ancient Roman villas were isolated? In Mediterranean climates temperatures can get close to freezing in the winter, and having an open roof like in the Getty Villa doesn’t help isolating the villa then. Google doesn’t give me an answer to that question. What was notable in the collection of exhibited artefacts for me was ceramic pottery which was cleverly disguised as if metal was the material. Unfortunately I did not have enough time to see everything without hurrying. I had three hours, but because I like to read all descriptions completely and visually analyse all artefacts carefully, I had to rush after seeing the first half of the ground floor to see the rest of the ground floor and the upper floor. After we arrived in LA we went on a bus tour through Hollywood, West Hollywood and Beverly Hills. The bus tour was okay, the idolization of celebrities which was obvious from audio descriptions accompanying the tour was not, neither was the heat wave in LA at that moment. We ate at a Thai restaurant of wide acclaim. I had never seen such a large menu before. I ordered the mussels here because they were recommended, but I thought they were nothing special. Other dishes were good though.

Day 15: Palm Springs

After one of the longest distances we had to cover with the car, we took the Aerial Tramway near Palm Springs. While it was over 40 ℃ below, on the top of the mountain it was somewhere around 25 ℃ and there was a forest there instead of desert. This was a good place for walking a few miles, and the mountain top gave you a good view over Palm Springs. We ate at Chinese restaurant again, also highly recommended and one of the best during the entire vacation.

Day 16: Scottsdale

On the way to back to Phoenix were we would take our flight back to the Netherlands, we wanted to visit Joshua Tree National Park. The distance was too long for us, so we turned back at the park entrance. For this day we had a hotel in Scottsdale. Even though we were staying in the area near Phoenix and Scottsdale for two days, we had two different hotels, don’t ask me why. My sister and mother insisted on shopping – even though they didn’t buy anything which they couldn’t get in the Netherlands – so we visited a large shopping mall. It was huge, far greater than anything we have in the Netherlands. For a standard of comparison, Hoog Catharijne is a provincial backwater compared to that. I also noticed a lot of teenage girls who looked like walking fashion industry advertisements, apparently spoilt by their rich parents.

Day 17: Phoenix

On this last day we wanted to visit the Apache Trail. I haven’t seen much of it, because no one wanted to walk the trail in temperatures near 45 ℃, neither did I. On the way there we came across the Goldfield Ghost Town & Mine, which is a ghost town. A commercialised, renovated ghost town to be exact, so the term ‘ghost town’ could not really be justified. I thought it had been better to skip it, until I we noticed some sort of small museum displaying large (living) snakes, reptiles and spiders. The guy who ran the museum, the Superstition Live Reptile Exhibit, told us passionately about the animals on display. Even though it was a very small museum, what could be seen here and this persons interest in telling us about the creatures made it totally worth the money. We spoke about our previous encounter with a snake in Zion National Park. When he showed us a bloody photo of some nasty surgical procedure on a snakebite victim, I’m glad the snake we met wasn’t aggressive at all and that we didn’t accidentally provoke it! Unfortunately I forgot to show him my snake photo so he could identify the snake. After that we drove to our hotel, close to the airport.

Day 18: Departure

We had to rise early at 5:00 to catch the flight to Washington, and transfer there to a flight to Amsterdam. Of course United Airlines, with its boasting that they’re number one in on-time arrivals in it’s advertisements, had to fuck up at this point. The airliner was delayed by 45 minutes. Fortunately Amsterdam was our final destination. If UA really scores best on the lowest amount of delays, I don’t want to know what the other American airways are like.

An even better example document created with memoir

Recently I had to work on writing a research report for a course teaching qualitative research. I had to work in a group with four other people. I asked them if it was okay if I would create the report with LaTeX, after showing them the beauty of my bachelor’s thesis which was also done with LaTeX they agreed. I don’t want to think of the horror if the report would have been created with OpenOffice.org Writer, or even Microsoft Word. The report (in Dutch) has already been submitted a few weeks ago and it was approved, so this is a good opportunity to demonstrate some new stuff I learned during the creation of the document. Here you can get the PDF document, here you can get it’s source. I’ll make some references to page numbers in the eigth edition of memoir’s manual.

I did some things differently in comparison to the document of my bachelor’s thesis. To start, I only specified A4 paper and 12 points font size as options for memoir. This means that the options twoside and openright are used because they are the defaults. The first option means that the document will be prepared for printing on both sides of the paper, the second option means that chapters always open on a right (recto) page. Memoir will insert a blank left (verso) page then if necessary. For my bachelor’s thesis I used oneside and openany (see page 4 in manual). Of course twoside would mean you print double sided instead of single sided for oneside, but I used double sided printing for bachelor’s thesis anyway.

Instead of using the \maketitle command, I used memoir’s titlingpage environment to create the title page (see pages 55-63 in manual). This allows for more flexibility which I required, but I think the title page could have been more attractive. I also used a table with fixed width columns which were respectively right and left aligned in order to align the names of the authors and their student numbers nicely. In LaTeX doing that was not as easy as it seems, see these and these instructions for more information. I used a different chapter style, called VZ23, which can be found here in a document with example chapter styles for memoir.

We needed to codify segments of interviews for our research, creating codes which divided into lower level codes. While I have not used them in the report, I wanted to make tree diagrams with LaTeX for use in a presentation (with the beamer package of course). I knew it could be done with the PGF and TikZ packages for LaTeX after looking at some examples. Those packages are very advanced, so advanced in fact that it’s manual contains a whopping 560 pages! That was overwhelming for me, but Google led me to a thread in a German newsgroup which contained some easy, simple code exactly right for the tree diagrams I wanted to create. This blog post also provided useful information.

Another challenge was creating a graph in the document. I had never done that before with LaTeX, until one of my colleagues asked me to insert a graph he had found in a research report he used as a source. He sent me a pixel based image, which was too small and blurry for my tastes. I don’t blame him of course, but I’m not content with anything less than vector graphics in a LaTeX document because those never get blurry no matter how far you zoom in. So I wanted to recreate the graph he sent me as closely as possible, which would also allow a larger graph to be inserted in the documented. I only knew how to create graphs with OpenOffice.org or Microsoft Office, but after looking some more at the examples of graphics created with PGF and TikZ, I stumbled on this example of a graph. In the comments the package pgfplots was recommended as more suitable for creating graphs than PGF and TikZ. After a few hours of reading the manual and experimenting with it I managed to create an almost exact copy (the source didn’t list exact numbers for the data displayed in the graph) of the graph displayed in the source. That required quite a bit of work, but the end result was totally worth it. The beautiful graph can be seen on the second page.

I followed this course at the Utrecht University School of Governance. They demand that the APA style be used for references, unlike the History department which requires the use of their custom style which employs footnotes. That’s fortunate, because I think I like the APA style more, and because there also is a biblatex-apa package for it designed for use with biblatex. It works like a charm.

I’m very content with it, but besides the title page there’s another reason why I’m not completely satisfied with the document. It’s the margins. I expected that the margins take some distance from respectively the right edge of the paper on a left (verso) page and from the left edge on a right (recto) page. Because at those edges the pages are connected to the spine, or in my case the place where I used a hole punch. That’s usually why you can’t completely see those edges, so that’s why I prefer the margin shifted to the outer edges of the pages. In memoir it’s the other way around, because space is reserved for margin notes (see page 8 in manual). Of course this is just a default which could be modified, but I didn’t bother.

Dragon Age: Origins and my attitude to playing style in video games

A few weeks ago a discount on Dragon Age: Origins and Dragon Age: Origins – Awakening was offered on Steam, and I took this opportunity to buy this game. Being a cheapskate (or poor student), I had been waiting for a long time for a discount to come, I knew it was supposed to be a great game and desired to play it since it’s release at the end of last year. Based on the previous games of the developer of DA:O which I’ve played with great enjoyment (such as Mass Effect, but especially Baldur’s Gate I and II) I had great expectations. My expectations were met.

This game rocks. The story is great, it’s got epic battles, it’s got cool finishing moves such as decapitations, the finishing moves for large monsters are even more impressive. The game also provides buckets of blood, which is spattered nicely all over your player character and his or her allies after they minced a group of enemies in melee combat. It’s quite comical to see conversations right after a battle, with the player character and friends talking or observing the conversation like everything is fine while they’re covered in blood.

There are some downsides as well. I bought the Digital Deluxe Edition, which includes some downloadable content (DLC), extra’s for the game made available for a price. One of those things includes a castle which you can conquer and then use as a base. Another one is an extra party member. Both are a disappointment in my opinion. Cleaning out the castle was cool, but after that all you can do is go there to buy and store stuff, and you can only enter the courtyard of the castle and no longer the interior. I remember Baldur’s Gate II, where you could also get a castle as a base. In that game, the castle generated income through taxes, and your posession of the castle also led to further story development, including having to defend your castle from an invasion. It’s a pity awesome games like that aren’t made anymore. Concerning the extra party member, that was material originally intended to be included by default, but later cut and relegated to DLC.

They should not offer DLC, they should include it in the base game and charge a higher price for it if necessary. Certainly with DA:O I have the impression that the base game is left deliberately incomplete (admittedly very slightly incomplete) because they cut features and then offer them as DLC. Besides asking money for it, the way the DLC is implented is annoying. It requires creating an account and being logged in over the Internet to authorize the DLC – for a game which does not feature multiplayer – a process which is not free from error.

I can imagine that with BG II being 2D and DA:O being 3D, it cost a lot more money to develop DA:O so they need to compensate those costs with more turnover. That could be the reason for the increasing trend of offering DLC, which I despise. But I wonder if the increased sales of video games, because they have become more popular and because DA:O like so many other titles has also been released on the PlayStation 3 and Xbox 360 (BG II was only made for the PC), isn’t enough already to cover the extra expenses? Given that Electronic Arts is the publisher, I wouldn’t be surprised if greed was the motive.

The game is quite affected by bugs, too. I experienced a few crashes. A few days ago patch 1.04 was released to fix some bugs. Yet still, the crossbows were apparently not fixed, leaving those weapons still useless. DA:O is still affected by bugs which need to be fixed, and meanwhile they’re already busy working on Dragon Age 2. This doesn’t give me much confidence in this sequel, maybe I should avoid it’s DLC, wait a year after it’s release to buy it heavily discounted, at a point when the bugs which have a serious potential to spoil the fun are hopefully fixed.

Now let’s reflect on my experience when playing DA:O. My perfectionism is easily seen in the way I play games. In shooters like Max Payne 1 and 2 or F.E.A.R. for example, I often quick load the last quick save I made before a shootout if I deem myself to have performed not good enough, e.g. if I take even the slightest amount of damage. Another motivation is creativity and the entertainment value resulting from it, which means killing the enemies in a creative way. I then quick load so that I can try it again, with a ‘perfect’ method so I take no damage at all. With creative I mean, to give an example in the case of F.E.A.R., to lure enemies into trip mines which I planted for an ambush, or to sneak up on an enemy and kill them with a kick, instead of plainly shooting them which is not as entertaining.

Of course not all games lend themselves to this creativity. A lot of shooters don’t allow for creative gameplay, Doom 3 being a good example. Multiplayer shooters often don’t either, for example Counter-Strike: Source does allow for a lot of creativity in tactics, but not in equipment for killing enemies. Half-Life 2: Deathmatch is a good example of a multiplayer shooter which does, because it features a very entertaining weapon, the gravity gun, and laser tripmines.

In certain role-playing video games – DA:O is one of them, but so is Oblivion for example – the best way to win is certainly not obvious. My perfectionism drives me to read FAQ’s and strategy guides on the Internet so that I learn how I can be more able to win, to play even better even if I could beat the game without any help.

When playing Oblivion, you can make your life much easier if you’re smart and creative, know how to exploit (not talking about cheating here) weaknesses and strengths of enemies and yourself, if you understand the mechanics of the game. For example, you can just charge at enemies blindly, or you can use invisibility and back stab them. I refer to this and this page for details, as you can imagine the tactics there can make a huge difference in your ability to defeat enemies. Being smart poses a challenge, because I like to be creative, but often can’t develop creative and smart tactics on my own when the game is role-playing game, they’re so complex. That’s why I need the Internet.

I feel that DA:O is a game just like Oblivion which requires quite some thinking on which tactics to use. I’m unable to kill the two dragons I encountered so far in this game, while I’ve seen a video on YouTube demonstrating that it’s actually quite easy if you use a brilliant tactic. There are many other video’s demonstrating easy kills of adversaries which are difficult on first impression. So far I’ve been playing the game at the standard difficulty, refusing to turn down the difficulty even though the game gave me a hard time at certain moments. Even though it could increase my (short term?) enjoyment of the game if I’d reduce the difficulty so I wouldn’t get killed so often, I refuse to do so out of a sense of self respect, even if it’s just a video game. I expect my enjoyment in playing the game would be far greater if I manage to follow the advice on the Internet and copy those tactics to realise those easy kills at the standard difficulty.

Looking back at Lost

For those who have been living under a rock, Lost is a TV series which ran for six seasons from 2004 to 2010 about a group of survivors who are stranded on a tropical island. Last night I watched the final episode on Dutch TV. Having followed this series for years and having seen every episode I feel this series has become a part of my life. In a good way I’d like to add, because I think Lost was an awesome ride. I think it ranks among the best TV series I’ve seen.

What I like about Lost is that it has a character and quality which many other TV series lack. There wasn’t a single episode of Lost which I considered to be boring. That’s a different story with the various Star Trek TV series, also one of my favorites. Those series contain many episodes which suck because they are boring and lack a good story, while they also contain many good and a few outstanding episodes.

Lost is also a TV series which I’d call very deep. Deep in the sense of being a TV series with many and very complex story lines, with later episodes being increasingly dependent on early episodes for understanding the story. Contrast this with shallow TV series. Like the various TV series of the CSI franchise which use the crime of the week format heavily. In CSI the crime which needs to be investigated in every episode runs the show, meaning the story is very short term, structural story telling spanning multiple episodes and characters are inferior as story elements to the crimes being investigated. While this makes good television for persons who don’t follow a TV series regularly and want to be able to ‘hop on’ at every episode, it makes for boring and unintelligent TV in my opinion. Another popular crime series like The Mentalist isn’t as bad as CSI in this regard, with the first episode revealing that the protagonist is searching for the serial killer which offed his wife and child. I had the impression it would be an interesting series to follow, but was soon bored because it involved many episodes using primarily the crime of the week format, and very few (yet more than CSI) long term story development.

Where Lost also succeeded is keeping the story line credible, the later seasons were not of a lower quality than the early seasons. I think Prison Break obviously failed here big time for example. The first season started of great, the second season was reasonable, but by the third season it was no longer credible when Michael Scofield found himself returned to square one and by the fourth season I stopped watching. The writers working on Prison Break didn’t have a solid long term vision on the story, and overextended the story after the success of the first season. Maybe they did so to exploit the success of that series, which they should not have done if they couldn’t do it right. I think the same counts for Heroes, another show which couldn’t keep my attention.

I’ll keep spoilers to a very acceptable minimum in this post, but be warned that some of the links I posted might lead to spoilers. Today I’ve spent half a day reading the Lost wiki Lostpedia to make sense of the whole series. When I’ve got far too much time on my hands maybe I’ll get down to reading this analysis, but for those who are time challenged like me this interpretation of the series is a good read.

All those years of Lost gave rise to a lot of questions regarding the mysteries in the story. Some are still unresolved are the finale, for example the nature of the island, the numbers the electromagnetic phenomena, the lethal pregnancies, the sickness. This isn’t necessarily a bad thing. The writers argued that they weren’t interested in providing definitive answers to certain questions, because providing answers takes away the mystery. I agree with them, mysteries stimulate our imagination, are something exciting, allow for analysis and making up theories. In fact, most of us like, maybe even need, mysticism. Many humans readily embrace religion without a scientific basis, not necessarily because religion provides answers where science does not; they have no problem with acknowledging that ‘God works in mysterious ways’. A completely rational world view doesn’t seem to be attractive for many humans.

There are certain aspects of Lost though where I don’t accept the absence of answers. A minor one is the question how what happened to the survivors of Ajira Flight 316 happened. It seems very strange that this question wasn’t answered. The only reason I can think of was shoddy planning of the writers who didn’t have enough space anymore to tie an answer in the story. A major one is the character of Walt. In the early seasons Walt’s character received a lot of attention, and it was clear he was very special. Then he got off the island, and after seeing the finale we can only conclude that he was irrelevant in the end. Based on what I saw in the earlier seasons I was convinced that he was going to be important, and it is very awkward to conclude that he was insignificant.

Also, I’d to thank the Dutch broadcaster of Lost, NET 5, for broadcasting the episodes of the last season of Lost only three days later than in the USA, unlike earlier seasons. That was done because they feared that potential viewers would get impatient and illegally download Lost instead. I’m delighted that Net 5 finally understands now that we don’t like to be an afterthought in Europe and get to see episodes of American TV series months after they aired in the USA.

Unfortunately, RTL 7 still doesn’t get it. A few months ago they finished broadcasting the seventh season of 24, not long before season eight finished airing in the USA. They’re not making haste with broadcasting season eight in The Netherlands either. That’s very unfortunate, because I’ve grown to like 24 very much after watching season seven. It’s a pity I didn’t follow the earlier seasons in the past, and I’d gladly buy it on DVD if it were affordable. 24 is extremely addictive, having mastered the use of cliffhangers.

Producing better looking multi-column documents with LaTeX

I’ve been using LaTeX to produce documents with two columns of text for some time now. Using two instead of one column of text improves readability because the eye doesn’t need to track long lines, and makes pages look better. All newspapers that I know of and many scientific journals use it. A two column-layout is easy to use in LaTeX, in principle you could add the twocolumn option to the document class, but using the multicol package gives you more flexibility because it allows you to switch between a single column of text and two columns (or more) of text in the document on the fly.

Unfortunately, LaTeX doesn’t produce good looking two column text by default. LaTeX often creates huge white space between paragraphs in order to get the two columns at the same length, which makes the document look bad. The problem is that by default the section heading (I only use two columns in articles, which contain only section headings) which is larger than ordinary lines. The white space before and after the section heading is not as large as the ordinary lines either. I found a solution for this in the manual of the memoir class on page 358 (in the version which was last changed at 12-03-2010). The code is as follows:

\setsecheadstyle{\normalfont\bfseries}
\setbeforesecskip{-\onelineskip}
\setaftersecskip{\onelineskip}

This way, the section heading is of the same size as an ordinary line, as is the white space before and after the section heading. If this code is implemented, the difference will be very noticeable, but there still is a subtle problem with white space between paragraphs. It can be seen in this document. I didn’t know how to fix this, so I consulted the experts. It turns out the following code is necessary:

\setlength{\parskip}{0pt}

This removes the rubber length between paragraphs. The resulting document can be seen here, along with it’s source. A difference is only visible on the first page though. When implementing these modifications, you will notice that the height of all lines of text in your two columns match exactly. It looks awesome, your document could easily pass as an article from a scientific journal now. Of course it gets a bit more complicated if you don’t want the white space before and after the section headings to equal one line, but that’s a problem to solve for another day.

Are sunglasses a necessity?

With the beginning of spring the weather has been very good in The Netherlands for the past week. Temperatures hovered around 15 ℃, and quite a few days were cloudless with constant sunshine. So I sat in the garden for long hours, studying the literature for my upcoming exams. Yesterday my father noticed me reading in the garden without sunglasses. He wears sunglasses all the time, and advised me to wear them too in order to protect my eyes from the sun. I should especially remember to take along sunglasses when we visit the USA in the summer. I refused, because I don’t think they were necessary.

My line of thinking is that if you see images from sunny places like Iraq or Afghanistan on the TV you almost never see the indigenous population wearing sunglasses, only western soldiers are frequently seen wearing them. You practically never see the Tuareg with sunglasses either, and if anyone would need them it would probably be them; they’re pastoralist desert nomads living in the Sahara and hence should probably experience the most sunshine, spend the least amount of time in the shadow or in their tents. I haven’t seen Afghans, Iraqi’s or Tuareg wearing hats either to protect their eyes from the sun. Another fact is that  sunglasses started to become widely adopted at the beginning of the twentieth century according to the Wikipedia article on sunglasses. So, assuming that sunglasses are a necessity for protecting the eyes from harmful sunlight, there should be ample of evidence that a huge amount of people who lived before the twentieth century should have suffered from eye damage. I have not been able to find such evidence, however.

After consulting Google, I found this article which claims that sunglasses are not necessary. It does mention a reservation however, if you are exposed to sunlight for too long (how long is not specified) you do have a higher risk of developing cataracts. Apparantly ’numerous studies have found that people living in high-intensity UV areas such as the equator have a higher incidence of cataracts than people living where UV is less intense’. There are also many results showing up on Google which tell me the contrary, that sunglasses are necessary for protection or at least give a less nuanced view than the article I just mentioned. This article for example, but I question the objectivity because it is written by a salesman of sunglasses.

As a scientist like me is obliged to do, I also fired up the scientific search engines like JSTOR and Google Scholar provided by my university’s library. Scientific articles confirm that sunlight can damage the eye, that sunglasses can protect the eye [1] and that sunlight is a cause of the development of cataracts [2]. But they do not tell me how much exposure, in amount of time or intensity, is required for the eye to be damaged. Other articles illustrate that results of studies vary, one study [2] asserts that wearing a hat or sunglasses do not alleviate the risk of developing ocular melanoma while another study [3] demonstrates that sunglasses do play a role in preventing the development of nuclear cataract. Different diseases of course, but it certainly doesn’t make it any easier. The question ‘how much is safe’ remains unanswered according to the fifth article [5]. The fifth article is also interesting because it questions the danger of sunlight for the eye under normal circumstances, based on the lack of scientific consensus.

With regards to sunglasses, I think I’ll take the middle ground. I won’t deny sunglasses have their merits, I’d certainly wear them during winter sport vacations because of the risk posed by snow blindness. When I was reading my books in the garden I also noticed sunglasses are more comfortable because the mostly white pages of books reflect a lot of sunlight, they’re a bit too bright for my eyes to keep looking at the pages for hours. But I’m not giving in to the exaggerated sunlight scare. The Netherlands doesn’t have as much sunny days as warmer countries, I don’t do much sunbathing, I don’t have a job which requires working in the outdoors for long periods. I try to avoid long exposure to sunlight anyway because prolonged exposure can be dangerous for the skin. In other words, I don’t think I’m running a significant risk if I’m outdoors without sunglasses for some hours.

Working suspend for TimeLine notebooks, new power consumption test

Great news reached me a few days ago when I read that there is a workaround for getting suspend working under Linux on various Acer TimeLine notebooks. See bug #405120 and follow the easy instructions. I can verify that it works nicely on the TravelMate TimeLine 8371 which I possess. There is a certain sense of irony in saying that this is good news though. Acer should have known this from the start and verified that Linux would work correctly on their notebooks, I can’t imagine that would have taken much effort for them. Even if they support only Windows, they could have made some of their customers happier if they prevented the problems, but it doesn’t surprise me one bit because I’m already quite familiar with Acer’s incapability to work in customer driven way.

Besides that, to follow up on my previous post I’ve done some new power consumption measurements on my TravelMate TimeLine 8371, this time with both beta releases of Kubuntu and Ubuntu 10.04 a.k.a. Lucid Lynx. The procedure was as follows, I downloaded the 64-bit desktop images of both Kubuntu and Ubuntu. I installed them both, I didn’t run them from the Live USB so that I would get accurate measurements. Important difference between vanilla 8371’s and mine is that I replaced the hard disk drive in my notebook with a Intel X-25M (second generation Postville) solid state drive. In both cases I disabled Bluetooth manually ith the key on the keyboard, because it’s always enabled by default. After a standard installation I didn’t do any modifications (except for the suspend workaround mentioned earlier to test if it would work) and installed PowerTOP, then I started measuring. PowerTOP was started with the sudo command, of course. The measurements which are mentioned were achieved after implementing  the various suggestions PowerTOP gives for saving more power. I mean only the suggestions which can be implemented on the go at the press of a key, on both Ubuntu and Kubuntu PowerTOP reported that several processes where writing to certain files on the disk which kept the disk out of power saving mode, I didn’t bother doing anything about those. Because I have an SSD instead of a hard disk drive it shouldn’t make as much of a difference anyway.

On Ubuntu I reached 6,2 W with WiFi enabled and having set the monitor to it’s lowest brightness manually with the keys on the keyboard. On Kubuntu I initially reached 7 W. That was reached after decreasing the brightness to the lowest level manually as well, it should be noted that Kubuntu doesn’t dim the backlight as aggressively by default as Ubuntu does. For some reason WiFi was disabled, the hardware button to enable it didn’t respond and the WiFi interface didn’t come up by default as soon as Kubuntu booted while it did with Ubuntu. Nothing was wrong with my hardware, because Ubuntu worked fine. Possibly my problem is related with the problem described here on the kubuntu-devel mailing list. Desktop effects were enabled manually on KDE, I’m not sure if Ubuntu enables them by default but I think so.

I decided to see if suspend would work. After suspending and then awaking my notebook I noticed that for some reason the WiFi interface came back up. When it came up again I enabled WiFi power saving when PowerTOP came up with the suggestion. After that PowerTOP consistently displayed power usage varying between 5,5 and 5,7 W for a period of ten minutes, for a moment it reached 6 W and then went back to 5.7 W again. I’ve never seen it reaching that low on Ubuntu, it makes me wonder if the measurement is reliable because Ubuntu doesn’t have the bug which causes the audio device to be active 100% of the time.
