New Windows 7 system: When I plugged in my headphones into the front audio jack, I immediately started hearing a buzzing and whistling noise in the earpiece. When I switched to the rear audio port, this noise went away. MP3s played clearly on both ports albeit with the buzzing noise in the background when using the front port.
Upgrading Sony's Xperia Ray from Android 2.3.4 (Gingerbread) to Cyanogenmod 10 (Jellybean 4.1) via Linux
So I wanted to upgrade my Sony Xperia Ray from its now old (and official) Gingerbread version of Android to the relatively more modern Jellybean. The most reliable alternative out there is Cyanogenmod.
While the Cyanogenmod wiki was generally useful, here's what I think is a cleaner guide. I performed the upgrade via a Kubuntu Trusty (14.04) laptop.
I've noticed a few people using the idiomatic phrase "prime of place" to denote the primacy of position in a group of things. For example, "My framed moustache-of-the-year certificate is given prime of place on the wall". While the idiom certainly appears to make sense, fits in quite well, and even sounds familiar, it is not really standard usage.
In Kubuntu/Ubuntu (and presumably Debian and other derivatives), the CTRL + ALT + F4 (or any other function key) keyboard shortcut switches from the desktop to a virtual terminal while CTRL + ALT + F7 brings you back to the desktop. However, I want to disable this as it's messing up my HTPC thanks to its dodgy remote control. While I could find a solution for Gnome/Ubuntu readily enough, KDE/Kubuntu was not immediately apparent.
I ran into the following error while running a script that was performing backups of files via rsync over ssh.
I ran into the following spiel when I attempted to SSH to a host just now:
Setting the timezone of an Ubuntu (14.04, Trusty) or Debian (7, Wheezy) server from the command-line is simple. Just run
dpkg-reconfigure tzdata and follow the on-screen prompts. However, if you are running an unattended installation, you might want to avoid interactive prompts and just gets the job done. To do this, simply run
$ sudo ln -sf /usr/share/zoneinfo/America/Anchorage /etc/localtime
/usr/share/zoneinfo/ to locate your timezone.
So, here I was writing a script that would automate the installation of a package in Ubuntu 14.04 and all was going swimmingly. Until I ran it. You know how some apt-get installs sometimes involve a technicolor pop-up that asks you for stuff? Well, those pop-ups interrupted my script which didn't proceed further. After much digging, I found that there are a couple of solutions for this:
bash: cannot set terminal process group (3987): Inappropriate ioctl for device bash: no job control in this shell
On a new Ubuntu 14.04 (Trusty) LTS server, I ran into the following:
$ su -c /bin/bash foo
bash: cannot set terminal process group (3987): Inappropriate ioctl for device
bash: no job control in this shell
su procedure worked and I was logged in as user foo.
After upgrading a Debian install to use PHP 5.4, I ran into the following error:
