Install KOReader on a Tolino Device

Tolino Debug Menu codes

For KOReader (or any other APK) to be installed on a Tolino device, the debug menu has to be enabled:

• if the tolino is on system version 14, search for code 124816 source
• if the tolino is on system version 15, search for code 1123581321 source
• if the tolino is on system version 16, search for code 112358132fb source

Note: "searching" as in the search for books on the tolino itself (the magnifying glass in the top bar)

# Why?
# To paste text into windows that normally don't allow it or have access to the clipboard.
# Examples: Virtual machines that do not yet have tools installed, websites that hijack paste
#
# Extended vs Simple?
# * Includes an initial delay to allow you to change active windows
# * Adds small delay between keypresses for slower responding windows like SSH sessions
# * Better handling of numbers
# * VMWare bug fix

How to recover pictures and files from failed MacOS / HFS+ hard drive with Linux

A couple months ago, a friend ask me to repair a failing macintosh.

It appears the hard drive has multiple failures from SMART anlysis.

Next reboot... Oh crap, the operating system does not start anymore. The drive contains 10 years of pictures to recover. A heart pinch :'(

Important thing to know, if (certainely) the disk is crypted and you don't know the principal user login password,

You can use IGV to automatically & programmatically load genomic datasets and take snapshots of regions of interest. This is very handy and helps you avoid taking many screenshots manually.
