We've tried tcmalloc, too. I don't remember the exact details, but we basically ended using jemalloc because it was using way less memory.
Same story with mimalloc - it usually provided a tiny bit more speed, but required more cpu and memory.
Several metrics are actually growing exponentially.
Power consumption and water consuption are the obvious ones. What are the others?Both rsync -avz /path/to/file user@server:/another/path/to/ or rsync -avz /path/to/file/ user@server:/another/path/to/file
Will create directory named /another/path/to/file which will contain all contents of the original directory (/path/to/file/*).
Basically, if you include the trailing slash in the source path, only contents of the directory will be copied (useful when you need to rename it).
rsync -avz path/to/old_dir/ user@server:/path/to/new_dir
If you omit the trailing slash in the source path, rsync will create the target directory for you. See man rsync for more info.But if you insist, I believe there are high-temp heat pumps available that will make better use of old-style radiators.
But still, it's not a red flag in this particular example.
You have to practice taking a step back, assesing the current situation and determining what's best for you. Ideally do this every time you feel like mindlessly doomscrolling. You'll get better at it.

And that's the difference. IIRC, you have to periodically top up your Suica card with money which then gets deducted from the balance each time you use it.
In Europe, there is no such thing - sure, you can buy a lot of single ride tickets and then use them when you need to, but you have to stamp the ticket when you start each ride, which does seem a little more inconvenient.
