I found the solution for a problem that has been annoying me for quite some time. I am using FVWM for a window manager. A few programs written in Java, most notably the Arduino IDE, will not accept keyboard focus. As soon as the window is given focus using normal window-manager commands, it immediately loses… Continue reading FVWM and Java application window focus

Free SSL certificates, part 2
Previously I noticed that StartSSL is offering free SSL certificates, ie. proper certificates with a CA chain that is accepted by browsers. Now while setting up my own web-server I had the opportunity to try it out. It seems to work well. The certificate seems to work, Firefox 3 does not spit out any errors… Continue reading Free SSL certificates, part 2
Hobbit monitoring
After setting up Hobbit monitoring on my home network, I discovered a curious issue with the Zyxel P-2602HW router that Fullrate delivers with their ADSL products: The Telnet administration port occasionally times-out connection attemps: I really like the Hobbit monitoring tool, I have used it ever since I heard about it when I met the… Continue reading Hobbit monitoring
Does the Flash plugin play dirty tricks with the X keyboard?
For a client, I am using a web application written in Flash. This application behaves really strange with respect to the keyboard on Linux x86_64 (Ubuntu Hardy). I re-map the caps-lock key as a control key (a required action for any hardcore Emacs user to preserve sanity). Now the application has a hotkey CTRL-SHIFT-F to… Continue reading Does the Flash plugin play dirty tricks with the X keyboard?
Installing GCC-4.3.1
I sometimes see even seasoned developers be reluctant to use a different gcc version (ie. to reproduce a potentially compiler-specific issue or just to experiment with new optimisations or features). The reason is a fear of breaking their system by installing multiple compilers, or even by replacing their system compiler with a new one. But… Continue reading Installing GCC-4.3.1
Free SSL certificates
It seems that one can obtain a valid SSL server certificate here at no cost. I will want to remember that for my next web site. I always found it a bit silly to not support SSL/https on a web site given that Apache has SSL support built-in. But it is a bit of a… Continue reading Free SSL certificates
Using GMail from Gnus on Ubuntu Hardy
I have used GNUS (Emacs news/mail reader) to read mail for ages, so I wanted to use it to access my GMail account as well. I managed to get it to work on my Ubuntu Hardy installation, though not without some hacking (I did not spend that long looking for a cleaner way). GMail supports… Continue reading Using GMail from Gnus on Ubuntu Hardy
Zepto Znote 6024W laptop
So I got a new laptop, a Zepto Znote 6024W. I got it with 2GB of RAM, a 7200RPM 120GB harddisk, 1440×900 screen, 2.4GHz Intel Core Duo CPU, and Intel Pro/Wireless 4965AGN. First overall impressions are quite good. The good stuff: Everything seems to work out-of-the-box with Ubuntu Hardy. You can customize the configuration when… Continue reading Zepto Znote 6024W laptop
Cool OpenSSH authorized_keys tricks
I have used the ~/.ssh/authorized_keys file with OpenSSH for ages. However, I always treated it as just a dumb list of keys, where I would dump my public key whenever I needed access to a new account or host. But today I learned from this blog entry that there is a bit more to it.… Continue reading Cool OpenSSH authorized_keys tricks
