To give some context, originally a ‘nazareno’ is somebody paying penitence for sins committed since last years Easter. Part of their ‘penitence’ is to march in procession covered with those robes. The ‘capirote’ (the hood) is intended to keep those sinners (that could be important or well known people) anonymous.

I’m not sure if this is still valid today or if it’s now just a performance. Someone from the south of Spain will more about that than myself.

Uh, no. The ‘devil horn’ sign, aka heavy metal salute DOES mean that. Thumbs up is just ‘thumbs up’ (it’s an imported/borrowed sign, as far as ai know)

In our case, everything ‘core’: checking and savings accounts, loans and credits, credit and debit cards… anything requiring a sub-second response time while being bombarded with tens of thousands of transactions per second AND requiring strict ACID transactions end to end AND 24x7 availability with quick recovery in case of disaster.

Secondary stuff is being moved to other architectures. And new core stuff is being written in Java… and ran on the mainframe.
