This sounds awesome. C is my preferred language and I use it whenever I can and when it makes sense. I'd love to see this code. Is there a public repo for it?

I've taken a slightly similar approach: If the information won't affect my behavior/actions, I choose not to invest time into it. This allows for me peruse headlines to be aware of what's happening (and to consider looki

For a lot of basic operations, this is often false. I have an application I'm working on and tested it across three different generations of CPUS going ~10 years back. The code was written in C and the fundamental steps were to: mmap()

I've spent a fair amount of time this year with liquid cooling designs, and final parts are coming in to do something along the lines of what you're talking about. Do you have any blog posts/videos walking through this? It so

Straight to payment for me. Sublime Text is one of the few pieces of software I've just felt was done totally right at so many levels. Entirely happy to give you more of my money.

Wow. When I saw your code, I thought to myself "yeah, but does it work when the socket is for a client?" Turns out, it does. My only guess is that I was botching something else when I was digging into this a few years ago. I can&#

I dealt with all of this in 2015, and spent three months trying to get epoll to perform similarly to kqueue; namely, to avoid returning on any and every packet received and, preferably, to abide by some sort of minimum bytes received (or co

Do you have a link to either an announcement of this change, or C code that demonstrates it? If it has changed, I might start doing some things differently...

Behind the scenes, Python may have another layer in there to check the socket options, etc, before returning. ie: Just because it looks like it's working on the Python level doesn't mean it's working the same way underneath.

My experience is across several years writing high performance http clients, writing in pure C.

It's also worth noting that kqueue() also doesn't use the socket options for this. Instead, it uses a flag called EVFILT_READ. More here: https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2

Given that I wasn't asserting that it is, I'm not sure what you're getting at. I was responding to the parent comment.

Correct. You can set those socket options and change the triggering behavior of epoll. But those socket options do not actually affect how epoll handles the data when it comes in. They are completely ignored by epoll.

by benwills 8y ago
There are other major benefits of kqueue() when using sockets as a client that have essentially "forced" me to use bsd instead of Linux/epoll... The way epoll () is written triggers so many syscalls that things like socket c

My interpretation wasn't that it was specifically that it's non-volatile. Rather, that it's the performance:price of NVME that's "changing the equation." The combination of NVME's IOPS and throughput, part

My guess is that you don't intend to be insensitive, but the awareness you're demonstrating here shows a lack of empathy and true understanding/acceptance of the emotional sensitivities to others, particularly this author. To

I would disagree with the reason being "because we've always done it this way." I started programming C full time about 2.5 years ago (after many more with PHP, et al). There's an aesthetic to writing C that I don't

I think that everything I'm willing to list publicly is in that post. Understand that almost all of it is written in pure C. [Edited to add: I do not use Java in any part of ontolo.] An example is that I do use Redis for some queueing

That makes sense. I don't know if this factors in, but I didn't post the link here. And if I ever did post a link here to ontolo, the HN post title would be very different. And I agree that few, if any, folks that talk about their

It's my pleasure. I love talking about this sort of stuff. As for the rate of requests, I just couldn't figure out how to max out the gigabit connection on Linux with epoll. I ended up moving to FreeBSD and kqueue, and when I did,

Hi Joe. I just saw this post here on HN. I'm the sole author of ontolo. Your comment about the ontolo domain and assuming it was a PR piece, is that because you know of ontolo as a marketing tool, or because it wasn't a more gener

This is great. It's one of those totally obvious ideas that everyone else just missed. Stick with it and keep refining and improving. The line of thinking is fantastic.

Not sure if others are having the same experience with it, but I'm finding it just beyond my comprehension, in the best way possible. So I'm not sure how I'd comment on it. And what I mean by 'just beyond my comprehensio
