When drives are never replaced, yes. In the case where the chassis lasts longer than the drives (which I'd imagine is often), extra cost in drives adds up.

The idea with having eBPF in the kernel is that we can limit the amount of trust given to a particular user-space task. Accepting compiled stuff in the form of a kernel module requires root privileges and requires that the kernel essentiall

`alloca` is a simple addition to the stack pointer, so a single instruction, presuming it isn't folded into the normal bump of the stack pointer to allocate the fixed size local variables. There isn't really much cost to doing a d

So the only things I'm seeing in the linked circonus code that differ from illumos: 1. no use of a kernel supplied page, determines skew/etc itself in userspace 2. stores information on a per-cpu level, and tries to execute cpuid

For those actually curious about the implementation on solaris/illumos, heres a quick rundown (from looking at current illumos source): - comm_page (usr/src/uts/i86pc/ml/comm_page.s) is literally a page in kern

distcc is not a cache. It doesn't keep the output of the compiler around after it builds things. It (only) distributes running the compiler around (and to do that handles some details of preprocessing, in certain modes) and then gets t

There is a per-user limit to the number of inotify handles available (max_user_watches) and the default value is 8192. The limit exists because there is a ~1KiB kernel memory overhead per watch (though there should really be a way for them

regarding "out of tree": I'm not quite sure about your explanation here (just looks like a list of source files), but presuming you mean "creates output files in a seperate directory from source", it doesn't re

The author also doesn't cover autoconf/automake, which operates in the same vein as cmake (generating files for use by another build tool). I agree, it would be useful to evaluate it here as it provides a bunch of the features the

Well, the front page did recently have people complaining about a bunch of paid products (github, twitter, everything IBM does). I'd expect us to treat open source projects like any other, and part of that is by noting their failings.

iirc, apt has support for it (it will only download a single thing at a time from a given host, but does appear to download different things from different hosts at the same time). I believe gentoo's emerge also has support (though I&#

I don't think it would be. Parallel downloads would simply mean that more of the client's bandwidth is consumed by connecting to multiple mirrors at once. Each individual mirror will, at most, still supply the same total bytes and

I believe the key phrase is "being used by". If they weren't reporting it, they could use the stronger "being reported to Google Analytics". Or "being collected by". Also note that by singling out Google A

I wonder if anyone has submitted patches to dbus-daemon adding support for non-systemd "daemon managers". If the article is to be believed it should be really easy. Maybe that could have been done instead of writing a blog post? O

Now we just need branch restricted keys & keys that aren't allowed to force push (both of these would make me feel a lot better about using certain 3rd party automation in combination with my github repos). Not that I really expect

I don't understand why you need a bootstrap toolset in C. Does go not support being cross compiled/cross compiling?

FYI: git supports rewrites to the implicit root commit with `git rebase --root` (and similar), there isn't a need for an extra empty commit.

I'm not seeing why they need to turn the switch ON twice. Couldn't they flip the switch only once and have the counter wait for <number of prisoners> ONs (N - 1 + 1)?
