inside the shutter

, , ,


This image, the phone blogging equivalent of a lens cap snap, was posted with Opera Mini 3, released today.

I decided to go through the regular process, entering my phone number (which I never remember, but fortunately my phone remembers it for me), guessing what the damn captcha said, and submitted. Sure enough I got an SMS giving me an URL to click on (it would be easier to enter the URL directly, but at least I know that the system worked, in the Czech Republic too). After downloading/upgrading and after running the selftest and entering the cryptographic seed, I clicked on the phone blog link (confirming that I wanted to get on the Internet and would allow Opera Mini to abuse the camera, two Java midlet application warnings you can't get around).

Then I discovered that midlets have no inhibitions against taking pictures with the shutter closed, unlike the regular camera application, so I just had to do it and posting the result was automatic.

This comment I wrote later as writing longer text from Mini isn't that fun.

Tip: Managing PDF files

, , , ...

I am using a fairly fresh install of Opera right now, with more default settings than I normally would use. One of these was the PDF file handling, like with other browsers (at least for Windows) Opera uses the Adobe Acrobat plugin by default. I do read quite a few PDFs, particularly work-related, and Acrobat is a fine program, but I really don't like the plugin. In theory integrating PDF files with the browser sounds good, but it takes away my control over my browsing environment, for instance I can't go back with Z (or a mouse gesture), and the plugin can't do all what the full Acrobat program can do either.

Fortunately this isn't hard to fix. What you need to do is to change the PDF settings.

  1. Open Tools > Preferences > Advanced > Download (Ctrl+F12,D should do it)
  2. Type PDF in the Quick Find field, application/pdf will show.
  3. Hit the Edit button
  4. Change the option to Open with default application
In some cases you might want to open with another program than the default. Personally I prefer, instead of just opening the PDFs, to store them in a particular directory and then open them. That will mean that junk files will accumulate in that directory as all PDF files will be saved there, but I don't read much junk PDF anyway, so cleaning up the directory isn't that much of a challenge.

New scientists and old religions

, , ,

The same issue of New Scientist had a report from an evangelical rationalist science congregation, under the theme of the atheists strike back.

But my question is: Is this good for science? Richard Dawkins' foundation, based on much the same idea, is discussed in the forums, the God-gutting comment in my previous post also elicited a reaction.

The next fifty years: it is all in the mind

, , , ...

My magazine of choice, (The) New Scientist, released its first issue 50 years ago, and more recently followed up with a hefty anniversary issue.

Reading news (or watching or browsing them for that matter) is a waste of time if you want to be informed or enlightened. I have argued before that instead of following flickering interpretations of what just happened it is better to use sources like New Scientist get an insight into what is going to happen.

Self-conscious at 50, New Scientist looked backwards for its New Zeitgeist in news articles past, as well as forward in inviting predictions for the following 50 years. While both are good reads, true to form it is the present, in the "Big Questions", that this issue shines. One present but unasked question is the role of science itself.

A test to determine the kind of action a scientific branch has is to look at the reaction. Since the time Galileo run afoul of his pope astronomy has annoyed nobody (well, dark astronomy annoyed me, which shows promise). The last public uproar based on physics were the anti-nuclear demonstrations in the 80's. There may be sufficient smokestacks left to give chemistry a bad name, but this is not where the battles lie. Meanwhile information has been the most recent inclusion into the physical system, and with the widest impact the last few decades. That notwithstanding all the theory was fairly established by the time the first issue of New Scientist was published, and thereafter nothing much has happened, and not that much is going to happen either.

Advances in physical science and computer science is now in the realm of usability studies and market research. It is no longer iconoclastic in nature, fundamental world views are no longer turned over by breakthroughs in physics. We will probably never return to the rapid and fundamental advances in the golden era of the late 19th century and the early 20th century. The physical sciences are a part of the establishment. Einstein is an icon, and we use quantum physics when we try to understand the world. If you observe two connected butterflies causing a storm a cat will die while staying alive, therefore if something is sufficiently garbled it is scientifically proven.

Biology on the other hand is upsetting. Christians largely in USA and Muslims largely outside of USA are rallying against Darwin, in a truly impressive display of rear-guard action. What other scientific theory of that venerable age can still muster the troops this way? But it isn't just the implicit threat to creation myths that gets us going. Genetic engineering, cloning, stem cell research... You name it, we protest against it.

Back to the big questions and the long forecasts. With some exceptions we were relieved of the hyperbole. Fifty years is not a long time, half a lifetime or thereabout. The world in the 1950s was very different in flavour to ours, but it wasn't truly alien. The world in 2050 won't be either. The forecasts in physics were largely completist in nature, reminiscent of card collectors, "if we just got these two missing cards we're complete". Based on past experience we will learn more if this completition project fails, but in any case an uninspiring outlook for us non-collectors.

I am much more enthralled that we are well on our way to discovering our past. Thanks to the invention of writing we have known tales from the past for quite many generations now, but what about the unwritten stories? Fossils may be among the oldest things around, but they have been new to us. As Andrew Knoll noted, most of the the artifacts of life and civilization remain in the ground undiscovered, but fifty years from now most will have been found. Non-intrusive survey methods will cover all the land mass as well as the seas. Digging for artifacts and fossils will not be the only way of inquiry. From the human genome project of the last decade, the neandertal genome project is well on its way. We are set to discover not only who we are but how we got to be, much of it from archelogical evidence in living genes in addition to communing with the recent dead.

Applied biology is provocative enough. But when it really goes home to ourselves it will be hard to ignore. Several of the articles touched the fleeting worry that when science has disposed of free will the way it did to phlogiston or the aether, what would prevent us from doing harm as it isn't our fault anyway?

This is reminiscent of when 18th and 19th century science gutted God good, the raised concern was how a society could survive and prosper without the fear of God to scare people into subordination. As you know we still turned out pretty allright. Demystifying our own behaviour will not make us into irresponsible people even though in a deeper sense we aren't responsible for ourselves. Put the other way around proving the illusory existence of self would not turn previously selfish people any more selfless. I may not exist but I still want that car.

Revolutions past

, , , ...



17 years ago, in a Friday November 17 far far away, the seminal event for the soon-to-become Velvet Revolution happened. The event itself, a sanctioned student demonstration ostensibly celebrating a martyr against the Nazi invasion 50 years earlier, mattered less than its aftermath: a fairly brutal police repression, augmented by a staged death by a secret police agent.

To my then jaded eyes, the depth of moral outrage among Czechoslovak citizen about this seeming police murder was endearing. This was shortly after Tiananmen Square (making everyone aware what was at stake), and even in Western Europe death by demonstration was not unheard of, or indeed 20 years earlier they had the self-immolation of Jan Palach and the 70-some killed in the 1968 Soviet invasion.

For me November 17 is connected with a fairly subdued plaque at the spot where the demonstration was stopped by the police. I don't remember when it was made, I think it was some time in 1990, probably at the anniversary. I do remember that in 1990 everyone would go out of their way to show you that spot, even if you had passed by a dozen times before. In the beginning were the revolutionary posters I mostly couldn't read at the time, then the candles, and finally the official plaque which was more or less the end.

The revolution itself officially lasted 11 days, including a theatre strike and a demonstration with an estimated half a million participants, which for a city of 1.2 million and a country of 15 million was an unmistakable signal the gig was up. The post-revolutionary euphoria lasted less than a year, it was commemorated a year or two more, and then the collective amnesia set in. Thereafter it was as it never had happened, it was never talked about. If I reminded anyone about it they were invariably embarrassed, a youthful and Un-Czech (the country had split by then) indiscretion they were aware of but rather would not remember.

As time went by a generation came to be that genuinely didn't remember it, because they never had experienced it (possibly apart from some weird and fragmented childhood memory), or the preceeding communist regime. That too embarrassed and secretly annoyed the slightly older generation. Until just recently when it became a subject again. Some of it was political, the high rating of the barely reformed communist party, as about the only protest party against the less than inspiring crowd of Czech politicians, did frighten the establishment and the anti-establishment alike. And youthful indiscretions are less embarrassing when you're not as youthful anymore. So nowadays it is a school subject, and if a revival is too strong a word (no expected theatre strikes) it is a reminder.

So today I decided to visit that old plaque. It is on one of the main streets, so it isn't as if I haven't passed by it countless times already, but I too haven't visited it for 15 years or so. It was much as expected, some strangely inappropriate posters and candles in massive appearance, to be taken pictures of by everyone in the audience with our camera phones. Having done that we all moved along.
