I decided to buy some chess books for the first time after many years. I’m going to start playing chess again, after several years long break. I think it might be a good step towards my mental recovery. I’ve been being busy with many dull activities last years and I haven’t got much opportunity to […]
I’ve been using two monitors with two graphics cards on my computer for long time. I’ve got another spare old CRT monitor so why not to utilize it? I connected it to a free VGA port on one of the cards and started experiments. Compared to the two independent graphics cards setup, using two monitors […]
I’ve been a user of Microsoft products for some time now. No, I didn’t install their operating system on my workstation of course. But I started to use their Natural Ergonomic Desktop 7000 wireless keyboard + mouse set. When looking for an ergonomic wireless keyboard several months ago I’ve found that the Natural 7000 set […]
Sometimes the possible consequences of connecting old flashes to modern electronic cameras (both digital and film) through hot shoe are discussed. The problem is high voltage (up to at least 300 V) of those flash units on their contacts, exceeding the standard limit of 12 V. I’ve never heard about a destroyed camera from direct […]
Some time ago I’ve finally managed to get my Epson R220 printer somewhat calibrated. Standard Gutenprint drivers suffer from strong green cast on this printer and I wasn’t successful to get it corrected directly in Gutenprint.

I’ve recently read an article from The Economist newspaper (reprinted in a Czech newspaper) about global positive changes of the world. Let’s look at some arguments presented in the beginning of the article. They say that number of people with income of one dollar per day or less has strongly decreased in China during the […]
About once a year I manage to attend a live music show. This year I’ve chosen Autopilote (Fajt, Smeykal, Yumiko, Holý, Václavek). I watched them in Noc s Andělem on TV a few weeks ago and I liked the music, thinking it might be nice to listen to it live. This opportunity came yesterday and the […]
We have moved from qmail to Exim recently on our company mail server. It is a big relief. The mail server can handle the high amount of incoming junk mail now, it is reasonably manageable and provides readable logs. It was late transfer. It is not easy to move a mail server to a completely […]
Amazon is going to sell their new e-book reader. Sure, I wouldn’t buy a proprietary device that serves as a purchase tool for a particular seller. But a more interesting thing is that they advertise access to Wikipedia several times in their blurbs. I’m curious whether Amazon is going to support Wikipedia, e.g. by donating […]
Film scanners are often claimed to be superior to flatbed scanners when scanning 35 mm films. The harder thing is to find actual facts supporting such claims. Actually it’s possible to find samples suggesting there is no significant difference between the scanners. And even Minolta was able to find the only relevant argument for film […]
