I am running ubuntu and last week the system didn't let me alter files as if I had no write permissions. Then on reboot the system did a check of the system which took some time. Then everything went normally.
Yesterday I was using matlab. I created 2 function ".m" files, and matlab crashed from an out of memory exception. This morning after checking my computer, I see that 1 of the files is missing, non-existant. What can I do about this? I heard of a folder called yesterday but I can't find it. If there are any other ways this would be great.
