# Boulder Dash for ATARI 2600, by Peter Liepa, 1984
# A Live Loop to algorave to.
# Original music (Youtube, Commodore 64 version):
# A pretty accurate transcription: (I can't hear any errors)
# Interesting note: Boulder Dash was originally written for the ATARI 2600 video game console, which had a TIA sound chip
# with two oscillators to generate tones (max polyphony was 2). So on both the Youtube recording (which is of a C64 port)
# and the MIDI score transcription, only two notes are ever played at once.

Rescanning a Linux SCSI device after it is changed on a VM Host

Sometimes when you change the logical drive of a VM from the Host, the device size is not reflected in the Guest. So attempts to use the extra space with fdisk or the NVM tools will not "see" the extra disc.

This is because the Linux kernel doesn't notice it, because it's not looking. Linux usually only scans this at boot time. But you probably can't reboot a server if it's live, so what do you do?

To tell Linux to have another look now, you just need to poke it:

echo 1 > /sys/bus/scsi/devices/1:0:0:0/rescan

View git-merge-origin\

This little dance is needed to merge in the remote origin/master to a fresh local (one created without cloning the remote, such as by a tool like pass). I don't know if there is a better way?

You need to do this when

  • you have another application which can use git for storing data, and you need to fill it with history from a common remote, but the application doesn't support git clone, only git init type operations
  • you have a local repository with local changes that you want to keep, but still merge in the origin (although you could go the other way, I think?)

Use commands like these to merge in a remote to your local master, as the new origin:


Import Keybase PGP to GPG

After installing the keybase command-line tool onto a new / fresh computer, you may want to import your PGP key to the local keyring so that you may use the keys with GPG.

Import your PUBLIC PGP key:

keybase pgp export|gpg --import -
