A friend of mine got stabbed a few years ago while walking home in Redfern (he survived and is okay now with no lasting injuries, but was in hospital for a while). It does happen here too.

No hate on ffmpeg but you can do this with mkvmerge as well.

Strictly speaking, one of the uses of eBPF is a DTrace-like tracing tool but it's also used in quite a few other places (for instance it's also used for devices cgroup policy in cgroupv2).

Honestly the GPLv3 really isn't that radical. It has three major changes along with a bunch of more minor cleanups and improvements: 1. Protections against patent trolls (similar to Apache-2.0, so this is a clear improvement over the G

It was never going to be possible for Linux to switch, so it's honestly a bit of a moot point. By 2007, the overwhelming majority of copyrights were not held by Linus and lots of the code was already licensed as GPLv2-only (not to ment

Rumours are not an effective way of discussing the safety of medicine, because they are naturally prone to all sorts of biases which skew opinion. Rumour mills are how you get witch hunts (and interestingly, the "witches" in those

Good for you, but swelling is a known side effect of so many existing vaccines (I linked the CDC page in my comment) that there's no reasonable justification in saying that this vaccine having this possible side effect is strange. Just

The EU minimum does not include bank holidays. The UK in practice has 20 vacation days (matching the EU minimum) plus 8 public holidays. It's just that the law is written that 28 days is the minimum including the 8 public holidays. The

I was thinking of the likes of France, Finland, Sweden, and so on which get 5 weeks, but yeah it seems the EU only requires a minimum of 4 weeks paid leave.

Does the US not have guaranteed vacation days? Here in Australia all non-casual workers must be given 20 days off a year (which in my view is actually too little -- in Europe workers get even more guaranteed days off). EDIT: This doesn&#x27

This is kind of the idea behind unikernels. There are experimental Linux-based unikernels, but the more mature unikernels are custom.

Cloud backends aren't really needed imho if you use something like rclone. Native cloud backends can make transfer order more intelligent but rclone does deletes last meaning you won't lose data if the transfer dies mid-transfer.

As the other commentor pointed out, I was wrong -- I'd mixed up the correspondence between kqueue and epoll with io_uring. Yeah kqueue doesn't allow asynchronous operations. Sadly I can't delete or edit my comment.

That proof (and the more general statement) is not correct because it makes assumptions about infinite summation of divergent series that are not true. There is a link between the sum of natural numbers -- namely, the analytic continuatio

You're quite right, I muddled things up (and now the edit window has elapsed). epoll is the Linux equivalent of kqueue, IOCP, and Event Ports (all readiness based). Not sure how I screwed that one up...

by cyphar 6y ago
Yes, sorry I muddled things up (and now the edit window has elapsed). io_uring isn't the same as kqueue because it doesn't permit asynchronous notification of job completion nor can you do more complicated chained operations, epol

My understanding is that it's unlikely cpuinfo and meminfo will be made cgroup-aware due to procfs-specific conventions on magic files. Making global procfs files change based on the current process is seen as a bad design these days -

by cyphar 6y ago
It should be noted that the reason this is wrong under Docker is that /proc/cpuinfo is not cgroup-aware. LXC works around this by creating a fake /proc/cpuinfo (and /proc/meminfo)[1] which matches the values se

You're quite right -- it's basically the same idea as IOCP on Windows, kqueue on FreeBSD, and Event Ports on Solaris.
594.
by cyphar 6y ago
kqueue on FreeBSD is effectively like io_uring but has existed for much longer (and Windows I/O Completion Ports predate kqueue). kqueue also gives you a way to get system events which you can't get on Linux (it has an equivalent

Solaris didn't port kqueue either. We're doomed to reinvent the wheel.

Yeah that part of my comment was a bit sloppy (I didn't mention vocabulary originally and then foolishly added it in a later edit). Cramming vocabulary does help make input more comprehensible, but it should be noted that cramming voca
