Downgrade OpenCV library on Fedora 18
Fedora 18 and OpenCV version 2.4.3 is not the brightest combination. After upgrading from FC17, python script has stopped working with displayed "SURF missing" error. I decided to downgrade OpenCV to 2.3.1 until this library problem will be resolved. Downgrade process is a little tricky, but finally my python code started to work on FC18 the same as it worked on FC17.
Fedora Core 18 NetInstall from USB stick
Post describes Fedora Core 18 installation on an old PC with no CDROM and no USB boot option in BIOS. Fortunately, PC had dual boot (Fedora 13 and Windows XP), so existing GRUB was reused to start installation. The solution was to copy netinst.iso image to the USB device and to load new kernel and initial ramdisk from it.
Fedora - grub Error 15
In my case, "Error 15" occurred right after Fedora installation. It seems that I didn't check somewhere during installation to write GRUB to the /dev/sda disk. After first reboot (while finishing Fedora installation), GRUB displayed "Error 15" message and booting was stopped.
How to install mplayer in Fedora Core 18
Mplayer Installation procedure is the same as is in my post "How to install mplayer in Fedora Core 12" but with some tweaks at the end. It seems that RPM Fusion repository didn't create needed symbolic links in /etc/pki/rpm-gpg directory. After symbolic link was created manually, mplayer / vlc installation has been finished successfully.
Restrict user login time for Fedora
In this post I will show how to control time access to the Linux desktop. This was needed for my son as a kind of parental control for his Fedora Core 16. Good news is that nothing should be installed because all tools and mechanisms already exist on system. With a little configuration across few files, Linux desktop will be locked for GUI login in defined period of time.

How to create FAT32 USB drive on Linux
In short, steps to create USB drive on Linux are: delete all, create partition, set partition type, mark it as active and write changes to disk.

Remove password from Virtual Machine Manager on Linux
By default, Virtual Machine Manager on Linux (in my case on Fedora) will ask for root password before starting up. Every time I clicked on Applications -> System Tools -> Virtual Machine Manager password popup appeared no matter I'm the only user on my PC. If you have the same situation, here are few steps how to get rid of entering root password each time you start VM manager.
Split and merge large files on Linux
Simple trick of how to split and merge back large files on Linux using split and cat commands. split and cat commands belong to the GNU core utilities which are expected to exist on every Linux operating system. Means, every Linux distro is already prepared for split/merge files and you only need to know how.

Android email and Postfix with authorization
I have been unable to send a company email from my HTC Android. The solution was to install and configure own outgoing mail server instead of using mobile providers servers. Now I can send an email quickly and easily, using whatever Internet connection is available - home, work, friends wireless connection, wireless hotspot or 3G dongle.
