Interactive fountain

A new toy in Budapest, Hungary: an interactive public fountain. Imagine a rectangle (about 10 by 5 meters) with jets of water shooting vertically up into the air at the perimeter. It looks like a room with walls of water. You approach the wall, and a small portion of that wall opens like magic (some parts of the jets stop working), you enter the room and the wall closes behind you (ie, the jets start working again). The same happens if you want to leave the room; you just approach the wall which gracefully opens to let you through. See the picture (click on it to get a somewhat larger image); it shows what happens…

That is whole idea. Simple but great; of course, many people enter the room at various places and various times, some of the jets are not yet in full force, etc, so it gives the fountain and ever changing aspect. When I saw it (yesterday) it was fairly cold outside, but I see in advance that in summer heat this will really be great fun!

As a techie: I tried to find and see the sensors that are, obviously, under your feet both inside and outside the water wall somewhere under your feet. I guess the trick is to have these sensors placed in a way that you do not see them at all to make it all really feel like magic. And indeed, though I tried, I did not see them…

Nice stuff!

Digital memories (or the lack thereof)?

Filed under: General,Private — Ivan Herman @ 18:15

A few weeks ago I visited my mother in the south of France. By moving around some furniture at her place we stumbled upon a bundle of old letters. Letters written by long gone friends from right after the War, i.e., around 1946, for example from  young American soldiers who were in Paris at the time when my mother was a student there. It was touching and also nostalgic to look at these old envelopes, written in a style and in a handwriting that that is really not of this time and age any more. But it is part of my mother’s life and hence, in some way, of mine, too.

However: what will I show to my son when I reach my mother’s age? I actually did write a some letters to my wife; after all, our relationship precedes the e-mail era. But we certainly do not do it any more. And my son’s generation clearly does not even know what it means to write handwritten letters to friends or family. It is all skype and facebook and email: although these can be archived, these messages are nevertheless inherently ephemeral.  What will he show to his children? We seem to loose something essential… and I am not sure what to put in its place.

Seduce with free services?

Filed under: General,Private,Social aspects,Work Related — Ivan Herman @ 8:01

I ran into this two times in a week. I hope it is just a coincidence…

The story is simple. You find some service on the Web which looks nice and helpful. There are various options: you may take a minimal service, which is free of charge, or you can also choose extra services for a fee. It sounds like a decent choice: if the minimal service fits your needs, you are happy, if you need more, you pay something. I presume we all use services like that.

But then… if you take the free option, you may get a mail after 2-3 years’ of  usage saying that sorry, the free service is discontinued next month; you are welcome to upgrade for the paying service, otherwise, well, good bye. As I said I got this type of mail twice in a week: one from a service giving a minimal synchronization of my phone’s calendar with Google’s, the other providing a simple email certificate for signing my mails. On a matter of principle I will not upgrade; I do not find this approach really acceptable.

So… will Gmail, WordPress, or other similar services decide that they have attracted enough customers, they can now start charging? As I said, I hope this was just a coincidence and not some sort of a general direction…

“Because a country using only one language and having only one custom is weak and frail”

I have already blogged a few weeks ago on the sad success of right wing extremist parties in Europe. One of the toughests and, in my view, most frightening one among those is the Hungarian “Jobbik” party, with its openly racist, anti-Semitic message. Being Hungarian, I feel embarrassed and saddened by their success… However, a new Facebook group, set up recently to fight against this Hungarian phenomenon, has made me realize a sad irony, too.

One of the historical figures of Hungary is St Stephen I of Hungary, the first king of Hungary. He established the Kingdom of Hungary more than a 1000 years ago, ensuring the future of his nation. As such, he has become, among others, the reference point for all nationalists and, of course, racist movements in Hungary.

St Stephen had a son, Prince Emeric (Imre); and St Stephen wrote a text to prepare his son to play his a role as a king. This old text, known as “Saint Stephen’s admonitions to his son Emeric”, is available on the Web thanks to the National Library of Hungary (sorry, only in Hungarian, I could not find an English translation). It consists of 10 general admonitions, the 6th being on the role of foreigners (the text actually uses the word “guests”) in the country. It would be a bit long to translate, but the title of this blog may be the most important sentence of the paragraph:

Because a country using only one language and having only one custom is weak and frail

(If you are interested by the original: “Mert az egy nyelvű és egy szokású ország gyenge és esendő.”)

Wise words coming from the “dark” middle ages! Worth for a number of people, from the Netherlands to Hungary, to think about…

The right-wing extremists on the move…

Filed under: General,Hungary,Private — Ivan Herman @ 9:24

The right-wing extremists on the move—in Austria, Hungary, Romania, Bulgaria, Greece, Denmark, the Netherlands. It is a shame— for the large people’s parties and for the voters, which did not participate in the elections.

This is a quote from a blog published on the Web site of the German ZDF television (see the German original). I couldn’t agree more. I live in the Netherlands, where Geert Wilders’ rasist party became one of the strongest parties in the country; I carry a French passport and the Front National will still send representatives to the EU Parliament in the name of France; and I also carry a Hungarian passport and the local right wing “Jobbik” party of Hungary has made a breakthrough yesterday evening. This is not a good day…

(Somme “nuggets” from the declarations of the EU representative of Jobbik: “I would be glad if the so-called proud Hungarian Jews would go back to playing with their tiny little circumcised tail rather than vilifying me”,…“We had a dream that we would not become a second Palestina. This dream has just come true…”. Wonderful…)

One can of course be optimistic: these movements come and go, they are in a minority. And I hope optimism is till o.k. But when I see these people marching on the streets of Budapest where I grew up, or when, as a foreigner in the Netherlands, I am indirectly accused by an official party of stealing the job of locals, then, well, it is not easy to keep up my optimism…

The art of consensus… in standards and in politics?

Filed under: General,Private,Work Related — Ivan Herman @ 12:20
Tags: , , , , ,

When you work at, or with W3C (or any other standard setting organizations, for that matter) there is always a discussion on the pros and cons of consensus building. It is hard to achieve, not always pretty, and it is certainly one of the reasons why the process slows down. But most of the participants also recognize the benefits, too. It is nevertheless not always easy to strike the right balance between consensus and speed, that is for sure.

I realized the other day that some of the political and economical discussions these days provide nice analogies. As we all know, the economical turmoils of the past few months force all governments around the globe to do something. But there is no agreement on what this “something” is; all governments are frenetically trying to give it some shape. This is also true in the country where I happen to live, namely the Netherlands. A few weeks ago the government made some dramatic announcements on the possible effects of the crisis, and also declared that major changes have to be done in the economic and social fabric of the country. And since then? Well, enter the typical Dutch approach: consensus building.

One has to know a little bit how the political system works in this country. There are elections, of course, and various parties make all kinds of promises before those. But after those elections comes the next phase: building a coalition (it never happens to have one party gaining an absolute majority). This coalition is based on building consensus. Future coalition parties come together, and they shape what is called a “government contract” (after all, this country built its wealth on trade!). This is a real contract, that all parties sign, and which reflect the consensus among the parties of what they can achieve together and what they cannot. Each party has to give up some of their electoral promises, but the whole country understands that and, as long as it is clearly stated in that contract, it is perfectly all right. From that point on, the government’s job is to, essentially, fulfil that contract. Of course, creating such a contract is a long process (last time around it took 5-6 months to build a government!). However, the result is that, comparatively, the stability of the Dutch governments, and indeed of society as a whole, is quite remarkable when compared to many countries around. In the 20 years that I have been here I have seen only a few minor strikes (nothing compared to France or Italy…), no major social unrest, and all this coupled with a relatively high living standard.

So to come back to the current state of affairs: the economic turmoils mean that, in fact, a new contract has to be signed because the old one has become, essentially, moot by the bank crisis. So the government parties and the major trade unions are now fiercely negotiating to find a new consensus. This has been going on for weeks and nobody knows what the outcome will be. Maybe I will have to work longer for my pension, maybe I will have tax reductions, maybe I will have to pay a higher tuition fee for my son… all these are on the negotiating table. What is interesting is to see the sharp contrast between this process and the way the crisis is handled in some other countries (like those that I follow more closely, ie, France or Hungary where the governments seem to take fairly one-sided steps without too much consultations with the rest of the society). The Dutch way is certainly way slower and, well, maybe more boring (it is more fun seeing strikes paralysing a whole country like France than just wait for these merchants to finish their negotiations:-) but, maybe, more beneficial on long term. We shall see of course, I may be wrong. But consensus building may prove beneficial again on the long run.

B.t.w., this Dutch way (which is also used in Belgium, actually) has even gained a name: this is the “polder model”, and it even has a Wikipedia page!

Classical Music and Improvisation (re: Gabriele Montero)

Filed under: General,Private — Ivan Herman @ 14:20
Tags: , , , ,

It was the French Classical Music channel (France Musique) that made me discover the name of Gabriele Montero. A great classical pianist from Venezuela (if a person like Marta Argerich says “I have rarely come across a talent like Gabriela’s. She is a unique artist.”, well, that means something). But what really caught my attention is that Montero does something very rare: she does classical music improvisation.

Musical improvisation has a strange history in Western classical music. There was a time when it dominated classical music: Bach was considered to be incredible improviser at the keyboard, and so were most of his contemporary musicians like Händel or Telemann. In fact, the tradition claims that some of Bach’s keyboard pieces are just the write down of his improvisations (the best known example is the “The Musical Offering” which includes a three-voice fugue for keyboard and which was probably the improvisation of Bach when he visited Frederick II of Prussia). And, in fact, even when playing “published” music a baroque artist was not only allowed to improvise a little bit here and there, but it was, sort of, expected from him.

But this tradition has disappeared. (I am not talking about jazz here. That is different.) Today a classical musician is supposed to follow the notes, the dynamics, the speed, etc, exactly as written down by the composer. Of course, this is not 100% true, musicians do have a great freedom of expressiveness, otherwise any machine would do. But it is certainly not allowed to deviate from the notes as written down in the music. Improvisation is not expected by the public, rarely practiced by musicians, not taught at conservatories. Actually, if an artist still does it, the “established” community of musicians will very often consider this as not “serious”, not worthy of a real classical musician… It requires a certain guts for a serious performer to do it in public.

Well… and Gabriela Montero has the guts. And that is why it is worth remembering her name. There are a bunch of videos on YouTube; maybe the one I prefer is a baroque style improvisation on Debussy’s Claire de Lune. Quite amazing: improvising counterpoint on the fly… She also has some CD-s where she recorded improvisations she made on Bach tunes (“Bach and Beyond”) or Baroque tunes in general. If you are interested in classical music but you also want to hear something a bit… unusual, then it is worth checking out!

B.t.w., she also has a web site (of course :-) where one can submit her a tune, she would improvise on it and send back the result in MP3. I might check this out sometime…

Internationalization and smart phones: an unhappy marriage?

Filed under: General,Private,Work Related — Ivan Herman @ 18:01
Tags: , , , , , ,

I recently went through the process of renewing my mobile contract which (in Europe) is usually a good opportunity to update one’s phone. Although my previous (smart) phone, a Nokia 9300i, served me well, an upgrade to a newer model is always a good idea. However, it turned out to be more complicated than I thought…

The complication is that I am a little bit off the beaten track, so to say. I live in the Netherlands, but I usually work using English, and I have text (addresses, data) on my smart phone in Hungarian. This also means using characters specific to this language (ie, ű, ő). Ie, I need a system in English, but with the possibility to, somehow, type in those characters, too. I have lists of all my books, CD-s, etc, that I have been maintaining for many years and I’d like to have around on my smart phone. I would not think this is too much to ask…

Of course, following the hype, I looked at the iPhone. Although I must admit I do not really sympathize with the business approach taken by Apple for iPhones and its applications, I thought I would have a look nevertheless. But… Apple doesn’t speak Hungarian. Neither does it speak Czech, Croatian, and other Central European languages for that matter, except for Polish. This means that there is no way one can type in those characters (and I am not sure it could display them all right). With all the hype around the user friendliness of Apple I was shocked to see them forgetting about cca. 30-35 million people who would simply want to use their own language properly. Exit Apple’s iPhone…

Next stage was Windows Mobile based smart phones; after all, it claims to be Unicode based! And there are some very sexy models out there these days (like, the HTC Touch Pro or Samsung’s Omnia), which try to compete with the iPhone. So I had a look. Using an English model the system gives you the possibility to use a virtual keyboard, and this indeed gives the option of using a “symbol” pad containing all kinds of characters including my Hungarian ones. A little bit awkward but, well, one can live with it. So, for a moment, I thought I was sold! But then came the shock: there is no way one can get a Windows Mobile phone with an English operating system in the Netherlands! Providers can give you Dutch systems only. To add insult to injury, for some reason or other, the Dutch system does not include that extra symbol key pad. (Why?) Ie, even if I accepted to use a Dutch system, it would not be usable. Exit all Windows Mobile devices…

My next target was Nokias E90. A slightly older concept than these sexy new breed of smart phones, no touch screen, no animation but, after all, who really cares if otherwise it does the job? It is sold as an upgrade of the old 9300i (where I had no problem with those characters), so I expected to have all features I was looking for without any problems. Wrong…:-( The E90 (ie, Symbian S60, the operating system) indeed offers you a way to type in accented characters. But, as a default, only the Western ones… Ie, no problem typing in œ, or ç, but no ű or ő (or characters like ř, č, ł, to refer to non-Hungarian ones, too). Ie, the E90 is actually a step back compared to its predecessor, where typing in all these characters was not a problem.

Dead end? Well, almost. Thanks to my colleague, Steven Pemberton, we found out that Symbian gives you the possibility to switch languages via what it calls “writing aids”. This changes the available character set. The models sold in the Netherlands have English, Dutch, and… Romanian. Why Romanian I have no idea. But I was lucky: although the Romanian language does not use ű or ő, it so happens that there is a significant Hungarian minority living in Romania, so the character set for Romanian included those two characters, too. Ie, I was off the hook, but that was shere luck, not design. If I want to type in a, say, Czech character (eg, if I buy a new CD of Dvořak) then, well, I will have to do some copy paste:-( But I had no choice so, after all, I decided to live with that, and I am now the happy owner of a Nokia E90. Story ends.

Don’t take me wrong. For a bunch of other things the E90 is a very very good smart phone, has a much faster processor than the 9300i, Web access is really a breeze (it uses Safari, afaik), it looks and feels great. Ie, it serves my purpose after all. But I dream of a time when internationalization is not a pain but a natural part of these devices (or any other device, for that matter)…

Web data visualization with ontologies

Filed under: General,Semantic Web,Work Related — Ivan Herman @ 10:14
Tags: , ,

It is nice to see when very different communities reuse one another’s work, ie, when the fragmentation of research and development into different fields is, at least a little bit, reduced… I ran into a paper Gilson & al[1] on “From Web data to visualization via ontology mapping” in a journal (the Computer Graphics Forum) that is usually not read by Semantic Web experts. So it may be worth drawing their attention on it… Instead of trying to paraphrase the content of the paper, why not simply reproduce the abstract:

In this paper, we propose a novel approach for automatic generation of visualizations from domain-specific data available on the web. We describe a general system pipeline that combines ontology mapping and probabilistic reasoning techniques. With this approach, a web page is first mapped to a Domain Ontology, which stores the semantics of a specific subject domain (e.g., music charts). The Domain Ontology is then mapped to one or more Visual Representation Ontologies, each of which captures the semantics of a visualization style (e.g., tree maps). To enable the mapping between these two ontologies, we establish a Semantic Bridging Ontology, which specifies the appropriateness of each semantic bridge. Finally each Visual Representation Ontology is mapped to a visualization using an external visualization toolkit. Using this approach, we have developed a prototype software tool, SemViz, as a realisation of this approach. By interfacing its Visual Representation Ontologies with public domain software such as ILOG Discovery and Prefuse, SemViz is able to generate appropriate visualizations automatically from a large collection of popular web pages for music charts without prior knowledge of these web pages.

Worth reading. And thanks to my friend David Duce to talk to me about it…
