DATAPUISTOKEMISTI

Pretty much any Linux should be fine as long as you have suitable scratch partition for temp Ubuntu install, in this example we're re-using 6GB swap partition. Process is two step, first we do minimal 32-bit Ubuntu install over swap partition, boot system, hack it to 64-bit and finally do final 64-bit Ubuntu install over old CentOS rootfs.

I needed to change colors of Windows 7 taskbar and window decorations from command line. Quick Googlioplaza search revealed AutoIT3 example , but it was bit lacking. See updated version below.

This is so great I'm shamelessly copying command lines for my own archive (aka this blog) - but also providing link to original .

Aufs included in Ubuntu kernels is broken, what a surprise. In addition it has been dropped from newer kernels with claims that overlayfs does exactly same thing. It doesn't and everyone knows it except that one developer who decided it does and can't admit he made mistake. It seems aufs (and overlayfs) in Ubuntu is not really supposed to be used but only be part of install process. If so you guys shouldn't include it outside installer.. WontFix you too.

Add "ohci-pci" to /etc/initramfs-tools/modules and run "update-initramfs -c -k all". This problem occurs because unlike other USB drivers ohci-pci is compiled as module.

Some time ago I purchased external 3TB USB 3.0 hard disks, TrekStor DataStation maxi light 3TB to be exact. It seem disk models and manufactures used by TrekStor vary, which is no surprise. Therefore I have externally identical disk enclosures with three different models of disks due making three separate purchases over few months.

Depending on why you're encrypting your SSDs it might be acceptable to enable TRIM (aka discard). With this configuration observing raw content on SSDs will reveal which blocks are used and which aren't. Doesn't matter for me, but might not be same for you.
