You're not considering the scale. We have faster iteration than upstream distros. More flexible. More tuned. I won't give exact details but 1% CPU gives extremely significant monetary savings, and there are at least 15% savings f

No, it's completely built from source, and finely tuned to the vast/quite homogeneous hardware, and deployment model. Though yes it is Linux based.

Even with dividends reinvested, $INTC gave zero real returns from Dec 1998 to now, and a net loss if invested after July 2014. Also $AMD now has a larger market cap, and $NVDA is 3 times larger! An amazing decline. https://totalr

Thank you for documenting those gotchas. I know not being a library has different considerations, but some ideas I used in timeout(1) to kill a process group may be useful. Tricky things like using sigsuspend() to avoid signal handling race

I agree that this is an awkward but very desirable property for a system to have. I was calling this "responsive idempotence" when discussing how the GNU coreutils are tested: https://www.pixelbeat.org/docs/co

Trying to differentiate GNU implementations had nothing to do with it. This is never a consideration for me. It was worth the slight increase in complexity for the reasons stated in the commit message. Also an unmentioned point is that the

Right. Faster generally means less CPU used for a particular use. For example I made ls(1) a bit faster recently. Even though not really noticeable per run, given how often it is run I estimated this to save 9 tonnes of carbon emissions p

I carefully considered this before I optimized GNU yes. The reason it is useful is because yes can output anything, and so is useful to produce any repeated data for test files etc. You can see the justification detailed in the original opt

I did this because it runs significantly faster with relatively extra complexity. It's useful for quickly generating test data etc

Yes there are inconsistences and surprises with trailing slash handling. For e.g rmdir doesn't follow symlink-to-dir/ on Linux. I tried to at least clarify what was happening in this case recently: https://github.com&#x

As a GNU coreutils maintainer, I'm happy to see another implementation. A lot of the coreutils development effort goes into testing, and new implementations should be able to leverage the existing GNU coreutils test suite, as it just u
