This is apparently where past exam papers can be found. Paywalled of course.
This adds to the mess of having a different location for material per department. Presumably this exists because the central university authority wants to centralize examinations to have better control over degree requirements. If only they would also do the same for all materials and end the mess.
The last value we will likely every know for the busy beaver function! BB(6) is likely completely out of reach forever.
By 2023, it had basically been decided by the The Busy Beaver Challenge as mentioned at: discuss.bbchallenge.org/t/the-30-to-34-ctl-holdouts-from-bb-5/141, pending only further verification. It is going to be one of those highly computational proofs that will be needed to be formally verified for people to finally settle.
As that project beautifully puts it, as of 2023 prior to full resolution, this can be considered the:on the Busy beaver scale.

Mostly video games of course.
First when he was really young, about 5, Ciro played a lot of NES, but he doesn't remember things from that era very well. Contra, Ninja Turtles, Battle Tanks, Duck Hunt, and some modern "real world jet" top to bottom rail shooter (TODO identify) are definitely some of the games he clearly remembers playing, see also: Figure "Five year old Ciro Santilli playing NES on a joystick". Nintendo hard was truly a thing back then.
As an honorable mention, Ciro remembers his teenage/young adult neighbours in Jundiaí playing some DOS games on their computer, notably there was a 3D racing one. This must have been around 1995/1997, so using some of the very earliest GPUs. Those games felt so incredibly advanced, including the required setup to play them, which required some command-line commands. It felt like some kind of black magic! But Ciro didn't really play them however.
Ciro then skipped the SNES and handhelds, which he played only through friends because he was cheap (but also because Brazil is a poor country remember, and imports are pretty expensive). He clearly remembers playing Super Mario World for the SNES and Pokemon on friends' Gameboys of course.
Ciro then went straight to 5th generation with the Nintendo 64 in 1994 which his parents bought for him during a trip to the United States. Once again, because he was cheap, the only game he bought was Super Mario 64, which likely came with the console? He played that game to death.
Then came Ocarina of Time, which blew everyone's minds, and Ciro would go to Blockbuster to rent it for the weekend, and again play to death with his friends. You had to arrive early at Blockbuster to rent it, otherwise other people would rent all copies!!!
The only time Ciro got robbed as of 2020 was when an older teenager stopped his bicycle in front of Ciro and took his rented Golden Eye 64 copy away from his hand, and run off. Poor drug addict.
Ciro always felt that the PS1 had a much uglier aesthetics than the N64, and didn't like the console. Playing a bit of Final Fantasy VI on his memory did stick deeply to his mind however. Ciro later played all good PS1 RPGs on emulation during University of São Paulo during amazing solitary nights.
And on the PC, Ciro was particularly touched by Age of Empires II and Diablo II.
As a young teenager Ciro would also play Counter-Strike with his friends at LAN houses. Playing that game would make Ciro extremely anxious, his hands got all cold, and it was a lot of fun.
After this Ciro grew up and notice that the only fun game is that of becoming become rich and famous in the real world.
Outside of video games, Ciro got midly addicted to Magic: The Gathering in his early teens.

You can't just shred individual sSD files because SSD writes only at large granularities, so hardware/drivers have to copy stuff around all the time to compact it. This means that leftover copies are left around everywhere.
What you can do however is to erase the entire thing with vendor support, which most hardware has support for. On hardware encrypted disks, you can even just erase the keys:
