Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to analyze a package/library?
I'm curious how ExaBGP works. In particular:
-
Java Library for BGP Peering?
I don’t know of a specific Java implementation but https://github.com/Exa-Networks/exabgp might fit in ok. Use exa to talk bgp but write java applets to “do things” with what exa hands you.

BGP Implemented in Go
> not to be tenable in Python
https://github.com/Exa-Networks/exabgp is written in python
- Has anyone worked with exabgp? Have question regarding return path traffic

More details about the October 4 outage
"Those translation queries are answered by our authoritative name servers that occupy well known IP addresses themselves, which in turn are advertised to the rest of the internet via another protocol called the border gateway protocol (BGP)."
"To ensure reliable operation, our DNS servers disable those BGP advertisements if they themselves can not speak to our data centers, since this is an indication of an unhealthy network connection."
Correct me if I am wrong, but here "DNS servers" means the computers, not the software running on them, i.e., each computer is running both DNS server software and a BGP daemon.
For example, with a BGP daemon like ExaBGP the output of a DNS query can be checked and routes could be removed if the query fails.

Tools to Explore BGP
13 years ago I wrote a nice reference implementation for BGP "client" use - I just treated it as an API onto Cisco routers: https://github.com/BytemarkHosting/bgpfeeder is 1300 lines of Ruby, one file, no dependencies, and quite verbose.
At the time I was running a hosting company & wanted to feed updates to our IP lists from a web-based database into our routers (e.g. a customer wants a new IP to their servers, or moves their VPS images between physical hosts). But I couldn't understand how to get tight control of quagga, or the Ciscos and wondered how how to speak it directly?
It took about a week poring over the RFCs and the Net::BGP Perl module, but I can go back to it now for some useful revision. It brought a lot of disparate BGP knowledge together in one place, and re-expressed it in a language I still know. So if you know Ruby and are curious about BGP it might help you see what you can do with it.
Though if you want to use BGP to control your network devices today, you'd use https://github.com/Exa-Networks/exabgp instead. It can pull every trick you could possibly want with BGP - e.g. DDoS mitigation, anycast, and generally letting you mess with BGP via JSON. There are lots of extensions to BGP, and I only cared about the ones to send v4 & v6 routes around. Also I only wanted to write it all in one file :)

Ask HN: Modern Day Equivalent to HyperCard?
I really wish Livecode hadn't pulled their opensource/Community Edition (and I'd be very glad for someone to do something with that code).
Gambas is something I keep wanting to try and seems promising.
I did one small app w/ Python and TKinter, but it was a dense wall of text/code when I was finished and not something I was interested in revisiting. I keep seeing suggestions that Python w/ QT support is supposed to be quite good.
One unlikely option is Google's Blockly (which I wish had a stand-alone desktop implementation which would make graphical programs), which has a nifty version implementing OpenSCAD:
https://www.blockscad3d.com/editor/
which I've used a fair bit. Moving on from there, there is: https://github.com/derkork/openscad-graph-editor which has the advantage of encompassing the entirety of OpenSCAD. It's also possible to wrap up Python using PythonSCAD.org
If you're willing to consider other node/line connection systems two promising options are:
https://ryven.org/
and
https://nodezator.com/
What sort of coding, on what sort of projects do you want to do?

Standardized, Python based Block Diagram File Format for Dynamic Modeling as an Open Source Alternative to Matlab and Simulink
There are general visual programming tools for python like ryven or PyFlow that should be able to run generic code, so in theory you can put SimuPy code in the blocks.

Ask HN: Visualizing software designs, especially of large systems (if at all)?
"What does an algorithm look like?"
I'm an intensely visual person, but have never found a visual programming system which scales well --- the problem is, past a certain level of complexity one has to use modules, which then devolves the visual representation down to just a bunch named blocks.
That said, I'm using BlockSCAD:
https://www.blockscad3d.com/community/projects/1421975
to work up designs which I'm then putting into other tools.
Looking at GraphSCAD:
http://graphscad.blogspot.com
and there's also Ryven and pythonocc which I managed to get installed:
https://ryven.org
https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven
but I'd really like to see a tool for this sort of thing which made G-code.
- my list of self-hosted (dev) tools
- Ryven – Flow-based visual scripting for Python
-
PyFlow – a tool for visual and modular block programming in Python
Why this over https://ryven.org/ ?
-
PyFlow – Visual scripting framework for Python – NodeRED alternative?
Interesting, came across https://ryven.org/ recently which looks in the same domain.
Any practical use cases of either being used?
Huge fan of NodeRED, always thought the paradigm could be leveraged for other heavy workflow applications

Blender + Ryven; leveraging the power of node editors in Blender by building on top of an open Python-based framework
I'm developing Ryven (https://ryven.org), a python-based visual nodes editor/platform. I recently published a tiny prototype plugin for Ryven 3.1 inside Blender (https://github.com/leon-thomm/ryven-blender). As Ryven is Python-based and quite easy to use, and Blender already had success with an integrated nodes editor, I would like to find out whether based on Blender's Python API it'd be possible to develop a large, powerful, compatible, and easily extensible framework of nodes for Blender that run on Ryven.
