This is an update on how to identify an URL stream using wireshark. In a previous article I explained how to install wireshark: http://puna.upf.edu/node/108
For some reason, radio stream providers are increasingly obfucasting the URL of the radio stream, probably because they want users to access their streams through their web page. So my old instructions do not work.
My new laptop XPS 13 9370 is great but I can ran it with such high display resolution (3840 x 2160 pixel 331 PPI) that I have to run it with a scale factor of 2.12. But not all applications scale appropriately. For Gimp I could solve it using a theme with larger icons, but some old X11 applications like Xfig, which I've been using since my Unix times in the late 1980s and could never substitute by anything else, don't scale at all. This is a problem since the menus and icons, as well as line thickness and such, are so small and thin that Xfig becomes unusable.
I have renewed my laptop after using my previous one several years. But what is remarkable is how easy it is to migrate both applications, its settings and the data from one computer to another one when you use GNU-Linux systems like Ubuntu, so that you can continue working in the new computer exactly as you were working in the old computer. Here you have some notes on how I did it.
As it is quite well known, Canonical decided to drop support for the desktop it had created and adopted in 2010, called Unity. The current version, number 7, is quite stable, but it has not received substantial update in the last few years, when Canonical and its community were waiting for a major update, Unity 8, which would allow for convergence with phones and tablets. Since I have quite a good workflow with Unity, I decided to keep using it until it is is possible.
I like to work hearing music, especially classic music. I also like Radio Clásica, the classical music radio of the Spanish public radio. In rhythmbox it is easy to enter a new radio, just entering the URL of the radio stream in the "Properties" field of the radio.
Since about a year ago I've lost my open IP in the University network and they forced me to move behind a VPN, with a lot of issues on how to maintain my workflow. But one of the most annoying things of this is that even the most basic things like using ssh or sftp may have new issues that are very hard to debug and for which I don't have any support whatsoever by the IT support staff.
My daughter asked me recently to convert an audio file that a classmate of hers had created with an Ipad. It was a recording of a class. I looked around for converters and was pointed to Audacity, but it didn't work (it asked me to upload it as raw data, but once uploaded there was no reproducible audio). Other solutions such as "sox" where failing saying that it could not decode the source.
Reading further I seem to have understood that there is still no codec for Linux. I also looked to some free solutions in Windows and I found some, tried one and was also failing.
It seems that talk has been started around the unification of packaging systems for various Linux distributions. There are currently different systems. Maybe the main ones are the Debian system (files with .deb extension being used among others by Debian, Ubuntu or Mint) and the RPM system (with .rpm extension, being used by RedHat, Fedora, OpenSuse and others), but there are more, for instance the Pacman system used by Arch Linux.
