I also find sequence diagrams to be the most useful, but disagree that the rest of UML is useless. Class, component, package, activity and state machine diagrams are all useful ways to model the structure and behavior of a system visually.The only reason the other diagram types fell out of favor is because of the development methodology change starting in the early 2000s. The industry started reje
There are a bunch of questions about Julia, so I'll do my best to give a short answer to a very long and complicated topic. Up front, Julia is a wonderful language and a wonderful community, I am a super fan.That said, Mojo is a completely different thing. It is aligned with the Python community to solve specific problems outlined here: https://docs.modular.com/mojo/why-mojo.html Mojo also has a b
If you trace this all the way back it's been in the Go networking stack since the beginning with the simple commit message of "preliminary network - just Dial for now " [0] by Russ Cox himself. You can see the exact line in the 2008 our repository here [1].As an aside it was interesting to chase the history of this line of code as it was made with a public SetNoDelay function, then with a direct s
I'm very interested in what types of interesting data structures are out there HN. Totally your preference.I'll start: bloom filters. Lets you test if a value is definitely NOT in a list of pre-stored values (or POSSIBLY in a list - with adjustable probability that influences storage of the values.) Good use-case: routing. Say you have a list of 1 million IPs that are black listed. A trivial algor
Hi folks, I'm the CEO of GitHub.GitHub hasn't been hacked. We accidentally shipped an un-stripped/obfuscated tarball of our GitHub Enterprise Server source code to some customers a couple of months ago. It shares code with github.com. As others have pointed out, much of GitHub is written in Ruby. Git makes it trivial to impersonate unsigned commits, so we recommend people sign their commits and lo
I have Raspberry Pi and I mainly use it for VPN and piHole. I’m curious if you have one, have you found it useful? What do you do with your Raspberry Pi? There's a bus station across from my studio / coworking space. I can see people waiting for the bus and doing either: 1) staring into the void 2) looking at their watches 3) desperately glancing in the direction where the bus is coming from.I fig
For instance what they use for stuff likehttps://git-lfs.github.com Or I don't know how to describe it, because right now I can't find an example, but more "comic" like maybe. I know that Venka Subramanian once had such a nice article about Akka with beautiful diagrams, but can't find it either :( Very surprised to see no one mentioning yeD here. It is _the one_ diagram making tool I go to, when I
I always push my devs to really study the Bittorrent protocol. The elements of the protocol are all fairly easy to understand, but it's gorgeous to see how elegantly it solved a social problem rather than a computational problem. The tit-for-tat and fast-finish protocols are incredibly graceful ways to create virtuous cycles in a social/technical hybrid, and replaced very real vicious cycles in pr
