Web Comics Dying?
Is it just an unfortunate coincidence, or are several web comics sites slowly dying?
For example, Order of the Stick is updated only every two weeks or so, User Friendly runs repeated strips for about a year now, and even BOFH has not been updated since last December, and had only 17 stories last year.
Did the authors manage to get a real life finally? Or have they been swallowed by the Internet black hole which is Facebook?

Wikipedia Warning
Warning: idling at Wikipedia can be dangerous, as it can destroy your image of completely innocent things forever.
For example, that nice, melodic, and gentle Paul McCartney's song "Mull of Kintyre" will never be the same again for me (click on your own responsibility).

Questionable Content
When browsing the Web, one can often find a content, which is - how to say it - questionable. Recently I have found an excellent example of it :-)
Questionable Content is a web comic written by Jeph Jacques. It is not only interesting and funny, but it also
contains humanoid robots, lots of rock music references (not that
I get most of those), occasional anime references, and the highest proportion of
characters with mental disorders from all the web comic strips. The only
annoying part is occasional filler strips and guest strips. But on the
other hand, it is actually released five times a week (unlike the
Order of the Stick these days).
For a light intro you can read for example the story arc beginning in the strip #1322 from a week ago. Or start from the beginning. Favourite character? Hannelore the obsessive-compulsive disorder, of course. Go forth and waste your time :-)

Ebooks and Copyright
Just a pointer to two interesting blog posts I have just read: Ted Ts'o discusses the ethical problem of wanting an e-book version of something which is out of print for a long time, and also has an interesting follow-up in which he discusses whether copyright is a matter of money (like most books or films) or control (like in some software, especially many copylefts like GPL). So what do you think about handling rights for the work which is abandoned for a long time, or simply which is not available in your local part of the timespace? And should rights for "static" work like books, music, films, photos, etc. be handled differently than rights for things which can be improved by further work of other people (like software)?

Without Visa?
Today's newspapers are full of articles commenting the fact that Czech citizens now can travel to the U.S. without visa, and taking it as a big achievement of Czech politicians. Having gone through the U.S. visa procedure myself recently, I wonder why no journalist pointed out the sad truth, that in fact, the visa procedure is still there.
The meaning of the phrase "not needing visa" for me is being able to decide to cross the border at any time in any country, and equipped just with the passport being able to appear in front of the passport officer, who in turn should immediately be able to decide whether to allow me in or not (possibly asking some trivial questions like whether I want to work in his country or in which hotel I want to stay).
But the current procedure is still the same visa procedure as before (including lots of big-brotherish questions and gathering of personal data). The only differences are that it takes only three days to validate the request instead of a month, it can be filled in online instead of in the U.S. embassy, and it requires a biometric passport (big brother again). And probably the immigration clerk would check the passengers without visa more thoroughly (at least this is how it has been a month ago when I travelled to Portland).
So nothing to see here (definitely no material for the front pages of the newspapers), move along.

Stitching Photos
In Oregon, I took several photos from one point in order to try to stitch them to one panorama later. The shots were taken from hand, so it was not optimal. In further experiments I would have to use a wider angle lens and higher overlap of the frames (I used about 20 % on each side). Manual exposition and focus is a necessity in order to get the same level of light across the whole view.
The image above is composed from eight photos taken at the Crown Point above the Columbia River. Best viewed using two wide monitors in Xinerama/XRandr dual mode :-)
The image has been created using Hugin, which is a really nice and intuitive software. I have been able to create the panorama without even reading the manual. Altough, reading their tutorials definitely helps (a funny bug there - the tutorial section labeled "Czech/Čeština" contains only one tutorial, which is actually in Slovak :-).
Stitching photos is another ugly case of software patents abuse: the algorithm for automatically detecting suitable alignment control points is patented in the U.S., which means that even though the patent is definitely not valid in Europe, precompiled software distributed globally (like Hugin) cannot use it.

Driving in the United States
I will not write about everything I did in Oregon (you can get better insight to the way of life in the US from the point of view of a foreigner in a Linus' blog), but there is one pretty interesting topic: my experience from driving a car in the US. There are several differences for the European driver:
- Automatic gearboxes everywhere. It was impossible to rent a car with manual gearbox. More on it later.
- The speed limits are pretty low. It is not surprising that US people go for a "bigger" car (SUV or large pickups) instead of the car that performs better (i.e. stronger engine and better-tuned chassis). When I asked about the speed limits in the car rental, they said: "I don't know - just follow the car in front of you."
- That said, nobody follows the speed limit - all cars were driving +5 to +10 mph above it. However, the speed variance among the cars was surprisingly low - i.e. everybody was drving +10 mph, there was virtually no overtaking. In our country it is quite common (esp. on multi-lane roads) that somebody follows the speed limit (130 km/h on a motorway), but somebody drives maybe 30 % faster. That said, the fatality per capita is about 50 % higher in the US than in the Czech republic.
- Apart from arrow signs (prof. Donald Knuth has a nice collection:-), there were almost no pictographic signs - everything was explained in words. Even some not so common road marking, like both straight and dashed line in the middle of the road, had an explanation board near its beginning.
- 4-way stop crossings, and the "first come, first serve" principle. Sometimes it was not very clear who came first.
- Traffic lights after the crossings. Several times I nearly missed the red light, simply because I have expected it to be in a different place (i.e. before the crossing).
- The car models were very different. While I have seen several models which can also be seen in Europe (Ford Focus, Chevrolet Aveo, and even one VW Golf), in general the cars in the US are different to those sold in Europe, even when the manufacturer is present on both sides of the Atlantic (like Ford or Toyota).
As for the automatic gearbox, it was pretty interesting. While the machine can change gears definitely faster than human, it cannot predict what the driver wants to do. For example, I when I needed to accelerate in order to overtake, the car (Chevrolet Aveo and then a brand new Chevrolet Cobalt) firstly choked on a current gear for maybe two seconds, then shifted to a lower gear, providing some acceleration, and just before the engine entered the RPM area of the highest power, it decided that it is still not enough, and shifted down once more, taking the engine to the red RPM values :-(
Maybe I would learn how to accelerate properly with an automatic gearbox after some more driving, but for now it is not usable for anything more than slow and careful cruising (which is how people drive in the US). However, I can imagine that an automatic gearbox with some tweaking (probably a "hold the current gear unless RPM is already near maximum" button and a "shift one gear lower" button) would provide the better from both systems.

Orange Sunglasses and Chromatic Aberation
I bought a new sunglasses for use on my bicycle. Somebody recommended orange colour because of supposedly better levelling between shade and light (which I often need, esp. on the forest roads), so I went for orange ones. I have discovered that when riding a bycicle, I see the edges of shadows coloured asi if my eye had chromatic aberation:
The edges where the sunny part is nearer to me tend to be blueish, while the opposite edges are yellowish. It is only visible when in move. When I stop, the aberation disappears. Can anybody explain this? The "when moving only" part could be explained by focusing to a different part, and seeing the shadows only marginally. Or is it a known optical illusion?

Lawful Ransom
My almost five years old compactflash microdrive in my camera has finally died, so I have decided to buy a new CF card. To my great surprise, about 10 % of the total price is the "authors fee". Which is law-imposed tax (a ransom, in fact) for supposed loss on authors' fees caused by distributing copyrighted work using this CF card. WTF?
Does it mean that having paid this ransom I can now legally use this CF card to transfer copyrighted work, as I have already paid the authors' fee? Or is there a way of getting this money back, provided that the card will be solely used in my camera, i.e. to store and transfer my own author's work? According to the Czech law, these fees are collected by a mafiaa-like organization named OSA, which then distributes it to their members (after subtracting their operating expenses, of course).
But in order to become a member of OSA, there is a minimum amount of author's earnings per year, which is quite high. Well, I really don't need to have a share on the total ransom collected by OSA, I just want back the money I have paid to them myself when buying this CF card. How can I do this, my dear lazyweb? A related question: is this ransom collected even for CF cards in embedded systems (think medical computers and other systems, where is no way they can ever be used for tranfering random files)?

The Best Deal
I normally try to avoid looking at banner ads in the web pages. However, today I have seen something which I nominate for my Daily WTF award :-)
It was an ad to a digital SLR camera (which is why I have looked at it at all).
The screenshot is cropped, it was twice that high, with the other half
describing the camera and saying that Circuit City offers the Best deal.
WTF?

Frying Pan
Our relatively new (~1 year) frying pan with teflon coating is becoming more and more sticky, so we are looking for a replacement. However, I don't think buying the new frying pan every year is the right solution to the problem.
So far the average lifetime of our frying pans has been slightly more than a year, with almost daily usage. After that, it either become sticky, or the teflon coating started to crack and fall off. And we are (at least moderately) cautious about the pan surface - we don't use sharp accessories inside of it, we don't put it in the dishwasher, etc.
The Wikipedia article on pans (marked as [[citation needed]] :-) says the following:
With the exception of cast iron frying pans, a Teflon coating can be applied to the surface of the pan to make it non-stick. This is popular for frying pans sold to the home user but less so for those used by professional cooks and restaurants. Cast iron naturally becomes non-stick through use and so would not benefit from a Teflon coating.
Is it true - do I want a cast iron pan? So far the Teflon-coated frying pans seem like an example of a product with a built-in obsolescence, designed to keep the manufacturer's cash flow steady. What about other materials (like titanium)? My dear lazyweb, what frying pan do you use/recommend, and what is the average lifetime of it?

Order of the Stick
Have you ever played a fantasy role-playing game like Dungeons & Dragons[?] (or a local variant
Dračí doupě)? And did you enjoy it?
Then you may want to have a look at the
Order of the Stick,
a quite funy web comics, which takes place inside the RPG. The image
is taken from the
OotS cast page.

Girls Everywhere
It seems that these days, every university or faculty[*] needs to have an attractive girl in their home page, presumably to attract applicants :-)
We had to follow the suit, of course :-) I brought my tripod, flashlight, and camera, and we spent some time taking photos. Tomáš then did an excellent work when creating the banner from my photos. While the title page and the page for applicants are nice, it still feels kind of weird to see the people I know in person in this banner. Oh, and BTW - this is my laptop they are looking at. To make them smile, I even displayed an episode of Azumanga Daioh there :-)
[*] the ESF page needs to be reloaded few times to actually get an image of a girl.

Energy drinks
Does anybody know how energy drinks are supposed to work? Last weekend we took part in TMOU 8. I have bought - probably for the first time in my life - an energy drink (its name was "Kamikaze" - lacking any other reasonable criteria for choosing an energy drink, I have bought the one with Kanji on it :-) in case I would get tired.
It was a bit cold during the night (I guess it was about -8 Celsius degrees), and at 4am I have decided that this was the right time for my Kamikaze. The results of drinking this very cold thing was strange: I have almost instantly felt very cold, and very sleepy. So I have laid down and fell asleep, while my teammates were trying to solve the stage 10.
Interestingly enough, when I awoke maybe half an hour or an hour later, I felt good, and I have solved the puzzle at the stage 10 in a very short time. Was it an effect of the energy drink? I don't think so - I remember TMOU in previous years, where short sleep has provided a big improvement in our performance as well, without any energy drink.
Do energy drinks actually work? What is your experience with them?
