Rachel's blog posts are brilliant for preparing for stuff like this. She's highlighted some great clues to look out for in the past, like seeing the constant 0x48545450 where it shouldn't be[1].
Hm, in that post Rachel mentions that 1213486160 is going on her list of magic numbers... I wonder if this list has ever been made public anywhere? I'd very much like to see it...
Well, yes, that's explained in the post. I'm not asking where the number comes from, I'm asking if the longer list of "magic numbers" can be found anywhere.
this somewhat feeds my impostor syndrome. as a regular old software eng I never got into a position where I could be seeing things like this. am I not working on hard enough problems?? this eats at my soul.
There's some good stuff, but there's also a lot of fluff and bad political takes.
It doesn't seem clearly better than Reddit's /r/programming board, just different and a little more eager to bury un-interesting posts. (but not controversial ones)
That said, I'm not aware of anyone at my company who reads Reddit other than me, either.
A lot of time ago I saw people here thinking in interesting ways about enterprises and side projects and said "hey, I want to learn that kind of thinking".
With that goal achieved, I think I stay out of boredom. (Like, at this exact moment, I have a script running at work that is blocking basically anything I can do, so I have 10 minutes.)

I would be grateful if someone can list some of them. (Maybe https://lobste.rs/ but I always forgot to look at it and I don't know anyone to invite me)
Perhaps I have not skimmed lobste.rs enough to make an accurate assessment ('cuz I don't know anyone to send me an invite, either), but lobster.rs just feels like a mirror of HN the times I looked.
Good content and comments get downvoted because of the hivemind, with some topics (linguistics, for example) taking it especially hard because, apparently, the hivemind doesn't like linguistics and downvotes content with accurate information on the subject.
Yeah, I saw the 40ms and something pinged in my head. Couldn't think of it though, but there it was in the article, Nagle's. The other article linked here also mentioned it. The term even means something to me in my current day job, as there's a switch to toggle Nagle's Algorithm in our application's UI somewhere (renamed it from "No Delay")
This can be accomplished with the TCP socket options TCP_CORK on Linux and TCP_NOPUSH on FreeBSD and OpenBSD. When enabled only full TCP frames are sent; upon disabling any partial frame is immediately sent. See tcp(7) on Linux, tcp(4) on FreeBSD, and http://dotat.at/writing/nopush.html clarifying the behavior.
I'm not a network guy and even I know about nagle. Then again I read a lot.
So the author and a colleague didn't know - 2 people who worked on a networking utility and had to spend days digging into it. The cost of reading books is high but the ROI is higher. Maybe they got unlucky but being a dev needs considerable knowledge but companies want their full stack devs cheap.
In the future, you should use this as an excuse to read more HN at work ;): https://news.ycombinator.com/item?id=24785405
