Cloud apps for Android are useless. Drive, OneDrive, Dropbox, Google Photos - all useless. Can't select a wide range of files or a single folder to backup, half of the uploads fail for no reason. I wish I'd left my raspberry pi online at home, so I could SFTP to it.
gf: "let's go, we need to visit 6 places and do it quick"
autistic me: "..do we need to solve TSP?"
gf: "what??"
me: "hold on a sec"
*googles "TSP Google Maps"*

This is very concerning- we are seeing evidence of significant changes in the brain even among people with relatively mild COVID-19. This study was in 46-80 yr olds, and many would've been healthy. We urgently need to understand the impact of COVID-19 in younger age groups too.

I'm back from a week at my mom's house and now I'm getting ads for her toothpaste brand, the brand I've been putting in my mouth for a week. We never talked about this brand or googled it or anything like that.

In 2011, RSA was hacked by Chinese spies, who stole the "seed" values used to generate codes on SecurID 2fa tokens, shocking the security world. Now, after 10 years, the NDAs of the staff involved have expired. This is the untold story they shared with me: wired.com/story/the-full-sto…
TIL glibc malloc may not release freed pages to the OS for a long time causing your RSS to blow up after repeated large size allocations and frees. Solutions: call malloc_trim(), tune with mallopt(), use madvise flags like MADV_DONTNEED, or just use mmap.
