Changing the setting redirects me to " https://www.dropbox.com/team/admin/settings/ai " in the Admin Console so I assume this controls it for the entire team.

Those are not the same. You can see cache usage in htop; it has a different colour. With MADV_FREE, it looks like the process is still using the memory. That sucks: If you have some server that's slow, you want to SSH into a server and

Yes, almost everybody who looks at memory usage in production will eventually discover glibc's memory fragmentation issues. This is how I learned about this topic. Setting the env var MALLOC_MMAP_THRESHOLD_=65536 usually solves these p

Be aware `jemalloc` will make you suffer the observability issues of `MADV_FREE`. `htop` will no longer show the truth about how much memory is in use. * https://github.com/jemalloc/jemalloc/issues/387#issueco

No. If you don't call fsync(), there's no guarantee that your data will _ever_ be written to disk. Some file systems with some settings may write data to hardware after some delay or periodically, but others may not. fsync() &quot

"memfd + linkat"? How shall that work? memfd is for files in RAM. linkat cannot get them onto disk. What you seem to have in mind is what the grandparent post already described: "O_TMPFILE + linkat".

The throwaway acccount is right. In POSIX, file content data and metadata (directory entries) are separate. Atomicity and durability are separate. It is likely that the LWN post author understands this very well, but omitted this important

What you say is correct, and ext4's current default behaviour can be quite confusing: * ext4 turns rename() into an invisible fsync(), if the target file existed. * ext4 turns close() into an invisible fsync(), if the opened file exist

That paper [1] is from 2010. What did "industry" use before that for pysically moving objects? If this is the current state of the art, are there generally-available/open-source libraries existing that implement this and prac

I am still confused by this too: Lots of typical "industry applications" given for Kalman Filters involve moving objects, like air planes, rockets, and so on. But all these objects generally rotate in some way, rotation is non-lin

Your syntax is incorrect, it should be data Profile = Profile { name :: T.Text , birthday :: Time.Day } deriving Show (You can't write `,` directly after `{`.) This is also why the commas are _not
