Thursday, July 17. 2008Context menu entry for video conversion![]() Sometimes I take AVI videos with my Canon PowerShot, and I process some of them with a video editor and export them as MPEG. However, those video formats can’t be streamed, and so I like to convert them to FLV to enable a YouTube-like streaming in web galleries by a flash video player. For convenience, I wanted to use a context menu entry for Nautilus, where I could right-click on a video file and select “Convert video to FLV”. Luckily, Nautilus supports to execute arbitrary scripts from the context menu if you simply place them into ~/.gnome2/nautilus-scripts/. The only disadvantage is that it doesn’t check the file type in advance, thus also showing the video conversion entry for non-video files. However, you can include that logic into the script itself. The script is a little more complicated, as I didn’t know how to better parse the file names. Probably I should have used Perl. Here is my ~/.gnome2/nautilus-scripts/Convert\ video\ to\ FLV:
Wednesday, July 16. 2008Wo das Netz dünner wird![]() Wir sind dzt. verwöhnt mit 16Mbit/s Downstream. Ich nenne diese Referenz im folgenden die 1-fache Geschwindigkeit. Für TV+Internet zahlen wir bei UPC jetzt noch den Studententarif von €55,60. Das Nette daran war, dass sich die Geschwindigkeit bei quasi konstantem Preis über die Jahre stetig verdoppelt hat. Dass mein Uni-Account mit November 2008 ausläuft, trifft sich ohnehin gut mit unserem Wohnsitzwechsel. TV werden wir in Hinkunft nicht mehr zahlen müssen (wegen gemeinschaftlicher Sat-Anlage), aber halt den Netzzugang. Festnetztelefonie nehmen wir nur dann dazu, wenn’s wegen des Internet sein muss oder preislich sinnvoll ist. Leider gibt es am Zielort kein Kabsi. UMTS & Co. sind glaub ich abseits des Ballungsraums keine ernsthafte Option. Außerdem will ich einen zentralen Zugang mit Router, damit auch andere PCs/Notebooks, evtl. sogar via WLAN, ins Netz geroutet werden. Das „volle Rohr“ von Tele2 schaut zwar gut aus, braucht aber offensichtlich (lt. Verfügbarkeits-Check) eine entbündelte Tel.leitung, die’s dort draußen aber noch nicht gibt. Abgesehen davon suchen die gerade einen neuen Eigentümer. Ansonsten stünde wohl folgendes zur Wahl: Continue reading "Wo das Netz dünner wird" Wednesday, July 9. 2008Surviving the aftermaths of the Debian SSL desaster![]() In short, and for non-computer-geeks: SSL certificates are used for data encryption, to securely transmit private data over the internet. You probably know web URLs starting with “https” instead of “http”. OK, now, those secure web sites may run on a machine that use the Debian GNU/Linux operating system. Unfortunately, Debian had a problem with generating such SSL certificates. They were recently uncovered to not secure your private data anymore. Luckily, a fix came out quickly, but there are still many websites using the broken certificates. You want to be alarmed whenever you stumble over a website that still uses one of those bad SSL certificates! You want the SSL Blacklist add-on for your Firefox web browser!
