Cap run.sh run at 2G RAM and 2 cores 
Running the courses made this machine stutter during a game. That was me:
PORR's suite solves systems up to 10000x10000 and takes every core it is
given, and the pip installs are not cheap either.

A promise to be careful is not a fix, so `run` now executes inside a transient
systemd scope -- MemoryMax=2G, MemorySwapMax=0 (OOM-kill rather than thrash
swap), CPUQuota=200%, nice -n 19, ionice -c 3. Same mechanism the pre-push
hook in testsAndMisc uses. Verified from inside the scope: memory.max reads
2147483648 and cpu.max reads "200000 100000", so the kernel is enforcing it
rather than the script hoping.

RUN_MEMORY_MAX and RUN_CPU_QUOTA override it for a single deliberate run.

Recorded the two courses that still fail: PORR, which will now be OOM-killed
under the cap and needs a smaller default parameter set, and ZPOB, where
latexmk exits 12 from bibtex despite producing the PDF.

README.md

WUT_Computer_Science

This repository aims to consolidate every single project I did solo during my Computer Science course on Warsaw University of Technology
It does not include projects I did in groups like:
EARIN
EDABA
ECRYPT
EOPSY

Thanks to some git magic this repo now CONTAINS all the group projects alongside with all proper contributors
