I talk about the cancelability state and how it can help us shortly after that statement: https://mazzo.li/posts/stopping-linux-threads.html#controlle... . In hindsight I should ha…

As I note in the blog post in various places if one can organize the code so that cancellation is explicit things are indeed easier. I also cite eventfd as one way of doing so. Wha…

Cancellation points and cancellability state are discussed in the post. In a C codebase that you fully control pthread cancellation _can_ be made to work, but if you control the wh…

This option is described in detail in the blog posts, with its associated problems, see this section: https://mazzo.li/posts/stopping-linux-threads.html#homegrown... .

This is noted in the blog post, but the problem is that sometimes you don't have the freedom to do so. See this sidenote and the section next to it: https://mazzo.li/posts/stopping…

(I'm the author) I don't really claim that Lanczos interpolation as presented is the "best" 2D interpolation there is. It is definitely popular though, and I couldn't find a source…

There was no battle actually, everybody (well, my boss and my boss's boss) was very supportive of open sourcing. And thanks for the kind words!

We do use Reed-Solomon codes, as the blog post explains.

No, we have our custom compressor as well but it's outside the filesystem.

The question is whether there are single Ceph deployments are that large. I believe Hetzner uses Ceph for its cloud offering, and that's probably very large, but I'd imagine that n…

I'm not fully up to date since we looked into this a few years ago, at the time the CERN deployments of Ceph were cited as particularly large examples and they topped out at ~30PB.…

(Disclaimer: I'm one of the authors of TernFS and while we evaluated Ceph I am not intimately familiar with it) Main factors: * Ceph stores both metadata and file contents using th…

I am, but I only type the messages I need to type. Which aren't that many. If there's some long explanation to be had I call or I leave a voice message. And yes, I am aware of the …

Note that I was fairly careless with it, and I'm pretty clumsy. It probably fell 20+ times. But still, it feels very cheap (and I suppose it makes sense given the price).

I've been using this phone as my full time phone for 1 year. It's a great compromise for people that ideally would not want a smartphone, but need to have one since many life situa…

gpderetta is right -- test/cmp + jump will get fused. uiCA is a very nice tool which tries to simulate how instructions will get scheduled, e.g. this is the trace it produces for s…

This post is an excuse to explain VM concepts, rather than a tutorial, something I maybe could have made clearer.
