If the servers in question happen to be on the list of supported hardware, quite possibly. (I don't know of any up-to-date online list, but running `source setup` in the root of the source tree will print it.)

Really? If you're going to do that, it seems like you might as well just merge all those users into a single account anyway, considering how trivial it would be for any one of them to execute arbitrary code as any other.

Until I can, as an unprivileged user, watch my own process's syscalls with dtruss, it's not an alternative to strace. Requiring root is a major hindrance.

Also (more specifically to one of the given examples), enabling `-A` on all your ssh invocations likewise seems like a pretty bad idea.

Fails to mention what is in my opinion the most devious, subtle potential pitfall with `set -e`: assigning (or even just a bare evaluation of) an arithmetic zero. `foo=0` won't do anything surprising, but `let foo=0` will return 1,

While this is a legitimate complaint, it also applies (though in fewer ways) to C. How do you parse this? (x)(y); Is that a call of function (or function pointer) `x` with argument `y`? Or is it a cast of `y` to type `x`? You need

I don't think the problems with that advice are singular. Perhaps the most ultimately-relevant is that looping exactly N times without a "ceremonial" counter is really only very rarely useful. Truly, how often do you see th

If I'm reading N1256 right (not sure how far back it actually dates, but that's a C standard draft dated 2007), section 6.7.2.3 also explicitly allows a trailing comma in that context as well, so if such a compiler exists its make

I'm reminded of an excellent quote from Bertrand Russell: "Everything is vague to a degree you do not realize till you have tried to make it precise."

Why are they using MIPS as a metric for comparing integer CPU performance? When you're looking at two different compiler backends targeting two (very) different ISAs, it seems pretty thoroughly uninformative.

Realistically it's not going to be that simple though. The filesystem proper (e.g. ZFS) may verify checksums when pulling in data from a storage device, but then it's going to sit in the page cache for some arbitrarily long time.

by 1amzave 11y ago
I think a reasonable argument could be made that if it's in the filesystem it's not end-to-end.

Is that really the definitive metric though? Seems like you'd want to compare overall program-text size between equivalent binaries for x86[-64] and $otherarch (i.e. x86 may be able to get away with fewer of those ~same-size instructi

Neat...and on a somewhat similar note (bash enable -f hacks), some bash FUSE bindings I wrote a few years back: https://github.com/zevweiss/booze I initially wrote it basically just for giggles, but was rather pleased

Looks neat, though I can't help but wonder if you'd be better off with DRBD (run it disconnected by default, then just connect and let it sync naturally when you feel like it).

I haven't actually used it myself and am certainly willing to believe it's immature, but how do you mean it has "little in common with RCU"? Comparing personnel between that library and this set of people --> https:

Yes, this essentially just a form of RCU. Note however that RCU isn't just for the kernel anymore though: http://urcu.so/

So what happens when you find yourself running on a CPU that wasn't in your initial affinity mask? Also, the "sleep for 1 ms" approach used in `init()` looks wrong -- if `sched_setaffinity()` doesn't guarantee that the c

Possible unintended side-effect: `taskset -p` might have "interesting" effects on your process.

Sure -- but my point was merely in regard to the (mis)use of the word "pure" here. Avoiding calling out to external executables and remaining purely within the shell itself is also frequently a good way to improve performance (so

Arguably not pure bash, in that it calls out to external executables. I'm pretty sure all the head/cut/tr invocations could be easily replaced by appropriate parameter expansions though, and the `read` builtin could probab
