Sázava and raft don't go together

In the last few years I used to descend some czech river with my friends during the summer. So far it has always been Vltava, for three times, and we were always satisfied with the trip. However, this year, we decided for a change and chose Sázava as the second most visited czech river. Unfortunately as it turned out later it was not the best choice. Especially because of the fact that we chose raft as our boat, because you don't have to care so much about the equilibrium of the boat and tremble that you will take bath at the next barrage and it's also more comfortable. But the necessary condition is that the river flows, at least a little, otherwise the trip on the raft becomes a bodybuilding excercise. And yes, I think it is clear now, that this is exactly the problem of Sázava. Unfortunately it is not the only one.

Pikovice train stop

As the starting point we chose Český Šternberk. However, due to little problems with the organization of the trip, we did not know that thare is no camp in the city until arriving at the place at 11 p.m. To build a tent on one of the meadows surrounding the city or river was not allowed to us by the reluctant local people even when we offered some money to them. Terrible. So we slept on benches behind the small local cinema (see photos). The following morning we put out to the river. The first day we managed to get to Chocerady and from there to Týnec nad Sázavou on the next day. This section can be characterized using only two words, boredom and toil. Sázava is in this 55 km long section absolutely motionless, so you can not choose but to paddle and paddle. Besides that, the surrounding countryside is rather boring as well. Also this section is probably not visited by watermans very often because the infrastructure on the shore is very insufficient.

KeePassJ2ME bug fix

Everybody knows it, for your day-to-day life on the Internet it's necessary to know dozens of passwords to different sevices. It's impossible to remember them all (for standard human being) so you have a dilemma whether to use one password for more services or write the passwords down. It's obvious that both of these options possess a high security risk, but that's not what I want to write about today. I used to write the passwords down to a standard text file in the past but after I've started to use a notebook I had suddenly the passwords copied in several places (PC, notebook, mobile phone) and I came to a conclusion that this might be the time to change the way I store the passwords, so it will be more difficult to obtain the passwords for a potential thief/hacker/cu­rious person.

I made some research and decided for a specialized application that will store the passwords in an encrypted form with one master password, that I will choose sufficiently strong and keep only in my head. I searched through the Internet and ended up with the KeePass application, that has everything I need and besides that is free of charge. The application itself has many advantages, that you can find out on it's homepage, but the most important one for me is that there's also a version for the Symbian operating system, that I have in my cell phone Nokia N73. This version is called KeePassJ2ME and should run on all mobile Java enabled phones.

Well, perfect, I downloaded the software (you don't have to install it), uploaded all my passwords into the KeePass database and removed all the text files. Subsequently I copied the database to my mobile and tried to open it. But! After entering the password the only thing I got was a java.lang.Inde­xOutOfBoundsEx­ception message. Nice. Nevertheless I have already decided to use the application so I decided to fix the mobile version. I downloaded the NetBeans IDE and even though I'm not a Java guy at all (I made only a few simple apps, none of them using the mobile Java) I began to look for the bug. It took me some time to figure out how to set up the application and compile it, i.e. how to create a working .jar archive, but after that the rest was quite straightforward.

The new web is here

I've done what I promised some time at the beginning of this year. It took me a little bit more time than I expected, but the new web is finally here and I hope you gonna like it. So, what's new? Well, quite a lot of things:

  • Newer, and hopefully nicer, design, but you've probably already noticed
  • The articles in the blog are now divided into sections and should be a bit more useful and interesting
  • The web structure is completely new, some things were removed (vox populi), new ones appeared (site map, breadcrumbs navigation)
  • SEO links are now used throughout the whole site
  • I've added a section dealing with my current Ph.D studies and a section about travelling, remaining sections were rearranged

However, the biggest thing is that the whole web is now bilingual, in particular, czech and english versions are available. The language can be switched easily in the top right corner of the page. Why? Because I hope that this will help me in getting more (foreign) visitors to my page and that I will improve my english during the translation, which is never bad. Of course I am aware that this is not going to be a simple task, as I don't know any other person running web in two languages. But the future will show, if it's maintainable.

Restoring the content from the old web is going to take me a while, I suppose a week or so, so please be patient. Also the comments are not working yet. This should be also fixed in the very near future.
