I have a little Linux box that I've been trying to use more frequently instead of my MacBook. Partially just for fun, partially because I want to decouple a little bit from the Apple ecosystem.
I was having a ton of stability issues: my filesystem would randomly go read-only after a few minutes. After trawling through my system logs, Claude suggested that it was a memory issue. I ran MemTest86 and it bailed out after 10,000 errors.
So now I was very depressed because RAM prices are sky-high and I currently cannot justify spending ~$150---more than what I paid for when I got this box used off of Ebay mind you---to replace the RAM inside.
Then I remembered my wife had an old laptop she hasn't touched in years lying around. I popped it open and, lo and behold, the RAM was compatible! I felt very fortunate that I was able to do that. Thoughts and prayers for all the folks who need memory---I've felt the despair.
