  • How do I change my username?

    - by Takkat
    Some time ago when I installed Ubuntu I chose a rather stupid username for my account that I do not want to use anymore. How do I change this (including the name of my home directory) without loosing settings for applications? How do I keep permissions and my keys for various authentification (e.g. email, SSH, GPG and more)? What settings could possibly get lost if I changed my username? Both, command-line and graphical solutions are appreciated.

  • Java GNOME bindings, are those a good idea?

    - by Phobia
    What do you think of Java's GNOME bindings and I was surprised to know that the latest version of the bindings was released this month and they're backed by a company that uses them, which means that there's a considerable amount of activity in the project, and that it's not going to be ditched anytime soon Is this going to be a second chance for Java on the desktop, since GTK+ is cross platform like swing, but less bloated and more responsive Should I be learning how to develop applications using it? or it's not worth the time?

  • Why am I getting such slow file transfer performance?

    - by kingdango
    Copying 4GB from a USB flash drive to my Linux partition. The flash drive is NTFS formatted (I believe, it's Windows formatted). The transfer is incredibly slow and blocks the computer frequently causing lag and hanging applications. My transfer rate is 1.2 MB/sec and that is the max it has hit when I let the File Operations window have focus. Why is this so slow under Ubuntu and significantly faster in Win 7?

  • Research topics for starting and optimizing a high-traffic website

    - by user745434
    I bury a good deal of my ideas for fear that I don't know enough about scaling web applications and high-traffic websites. That said, I'd like to know of any general topics to research in order to ensure that your web app doesn't break / slow down when you start getting to Twitter-level traffic. I'm looking for research topics with, preferably, additional resources. For example: Make sure you optimize SQL queries (see High Performance MySQL Optimization)

  • Is there another way to restart Ubuntu 12.04's sound system if pulseaudio/ALSA don't work?

    - by Ricardo Altamirano
    I was listening to music, and my sound suddenly went dead in all my applications. I'm using Ubuntu 12.04, which uses pulseaudio, so I tried sudo /etc/init.d/pulseaudio restart, but nothing happened. According to lsof | grep pcm, nothing is using the soundcard at the moment, although I'm not entirely sure if my source for that command is applicable. Is there a way another way to restart Ubuntu 12.04's sound system from the command line without rebooting the system?

Are other companies working on a similar offering? What would it mean for the browser landscape?
