ChatGPT often presents wrong information with complete confidence. This creates a dangerous false sense of reliability. Users waste time fact-checking basic claims that should be correct.

For your use case, I’d recommend looking at Lenovo ThinkPad P1 Gen 6 or Dell XPS 15/17 with an Intel i9 or Ryzen 9, 32–64GB RAM, and NVIDIA RTX 4070 or higher. If you’re open to desktops, a custom build with a Ryzen 9 7950X, 128GB RAM, and a decent RTX 4080.

Great, thanks for sharing. However, adding 'nsfw' returns different and unrelated content. '-noai' works well.
> Why has a search company
Google was a search company, many years ago.
Today's Google is an advertising company that just happens to have a legacy search division.
Well said. Feels like search is now just the wrapper around the ad engine, not the core mission anymore.
Use a desktop client like Thunderbird or Mailbird that downloads your emails locally and lets you run more reliable full-text search.
Some people also use IMAP + grep by syncing to a local folder. It’s frustrating that the world’s top search company can’t deliver consistent search in Gmail, but for now, third-party tools do a better job in edge cases like this.

Boring but
docker ps
docker kill
git switch
git commit
git push
Not boring at all. These are the real “daily drivers” that keep things moving.

I use pgrep -fl <name> instead of ps to find running processes by name.
For complex one liners, I keep them in a simple txt file with a brief description so I can find them later when I need to use them again.
Smart move with pgrep -fl—so much cleaner than piping through ps | grep. And keeping a personal cheat sheet of one-liners is underrated.

Not really a shell one liner, but ctrl+r (a readline command to do an incremental search backwards through history) is something that has been present on every shell I've used for decades without realising it, One day I decided to take the time to read all the magic readline commands because I wanted a way to quickly edit the N-th argument of a command with lots of arguments, and there were way too many of them. There were so many commands that I had no hope of remembering them all, but I figured I could just remember a few useful ones - and ctrl+r was one of them (ctrl+w and alt+b were the other two)
More to the letter of the question, I use "cd -" frequently, "ps -e | grep some_process_i_would_like_the_pid_for", and while I don't use it frequently, I didn't know about "ssh-copy-id" for a long time, and would do it manually with a text editor in the past. Sorry if they are not sufficiently fancy - but for things to get used day to day for me, they will need to be short and sweet.
No need to be fancy. These are super practical! ctrl+r is a lifesaver once it clicks, and cd - is such a small thing that makes moving around so much smoother.

Daily, and with enough general usability to share? I have a few. They are basic. You can probably figure out what industry I work in.
df -h /; echo "----"; for fattable in $(find /var/lib/mysql/ -name *.ibd -size +1G -exec ls -lh {} \; | awk '{ print $9 }' );do echo BEFORE " " $(ls -lh $fattable| awk '{ print $5" " }'); db=$(echo $fattable| cut -d/ -f5); otable=$(echo $fattable| cut -d/ -f6| cut -d. -f1); echo mysql -qbse \"use $db \; optimize table $otable\;\"|bash;echo AFTER" "" " $(ls -lh $fattable| awk '{ print $5" " }');echo "----" ;done; echo "----"; df -h /
apachectl fullstatus | grep ^[0-9]| awk '{ print $12" "$14 }' | sort | uniq -c| sort -n |tail
tail -100000 /var/log/nginx/access.log | sed "/$(hostname -i)/d" | awk '{ print $1" "$7 }' | sort | uniq -c | sort -n | tail -050
find . -mtime -1 | cut -d/ -f2 |uniq
pkill lsphp; sleep 2; while true; do sleep .4; strace -p $(ps aux | grep [i]ndex| awk '{ print $2 }' | head -01); done
for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " " $3}END{ print ""}' $file 2>/dev/null; done| awk '{ print $2" "$3" "$1 }' | sort -n | tail -20
find . -size +200M -exec ls -lh {} \; | awk '{ print $5" "$9 }'
awk '{ print $4 }'
That’s an impressive collection. Definitely not basic! Love how practical these are for real-world ops work, especially the MySQL .ibd optimizer loop and swap memory check.
