Restore GRUB2 MBR from SLAX Linux

When you log in into slax type:

mount -t proc proc /mnt/hda3/proc
mount -o bind /dev /mnt/hda3/dev
chroot /mnt/hda3 /bin/bash
grub

then

find /boot/grub/stage2
root (hd0,2)
setup (hd0)
quit

Then exit and reboot.

I always keep forgetting how to do this properly, so this is the case:

mkvmerge -o "outputfile.mkv" inputfile1.mkv + inputfile2.mkv

I wanted to have my RAID5 array to go to standby after 10 minutes of inactivity. I achieved this with:

/sbin/hdparm -S120 /dev/sd[a-i]

But my drives were waking up from their standby because I had mythtv-backend configured with UPNP support. Continue reading “Stop HDD drives waking up in mythbuntu”

In putty enter hostname or IP address and port on Session page.

In Connection > Proxy settings enter company proxy IP and port set it as HTTP proxy.

In Connection > SSH check enable compression and version 2. Continue reading “SSH tunnel trough proxy in Putty”

Go to Start > Run > and enter “CMD /K WMIC OS GET InstallDate” then press Enter.

New window will open with contents similar to this:
