There are two options for - soldering the diodes. The end where that color-mark is denotes the direction of the diode.

However if - you want to try and use the "tmk_keyboard" firmware which seems to be also interesting you - want to wire the diodes the other way. This way the "columns are driving". As a side note, if - I understand it correctly the tmk_keyboard firmware thinks of rows as columns and the other - way around. - - The tmk_keyboard firmware could also be used for this kind of wiring, but it would have to be - rewritten, maybe in a beautiful way, such that it can also "drive rows".
