And finally end up with either jemalloc or possibly mimalloc. ;)

we actually ended up with (new) tcmalloc.

for us, tc was among the fastest in runtime while being very space efficient [0]. large rust application using far too many threads.

we’ve since also had great success with tc’s built in profiling tools.

Invariably so but I'm mulling over malloc()s on embedded topic now.

    Several metrics are actually growing exponentially.

Power consumption and water consuption are the obvious ones. What are the others?

Do you want to understand what this obsession is about? You probably need to visit Japan more.

I read that as a statement that says something along the (nowadays very tired) line that the cloud is not magical, it's just other people's computers.

Yes, but try rsync instead of scp. Mind the slash though!

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.

Exactly. And there is a lot of other alternatives in this space, check the guides at https://runrepeat.com/

Why keep the cast iron radiators?

But if you insist, I believe there are high-temp heat pumps available that will make better use of old-style radiators.

Or maybe not, because that's where confusing 180 and 360 degrees or headwind and tailwing will REALLY bite you.

Sure, but if you come back, you'll have really learned that stuff!

USB-C charger, not cable.

My Claude says that a decent cable has an ARM Cortex-M0 running at tens of MHz, while the Apollo Guidance Computer was 1MHz. I am afraid to think what a charger packs.

I find that hard to believe, but maybe it's just that the speed of the technical progress is way too fast nowadays. :)
