ThreeFlow | Engineering Manager, Software Engineer, DevOps | Remote Only | USA | https://www.threeflow.com

Hey! We’re an insurtech startup that has just announced our 45M Series B and is subsequently growing! In order to scale an engineering org with intentionality and care, we're adding three engineering managers to join us to thoughtfully look after the expansion of our three product development teams.

I've thought a lot about how to position this role/job description so that people are successful from day one. I'm looking for folks who sincerely enjoy people management (hiring/mentoring/supporting the team) as well as perpetuating an inclusive working environment. If this sounds like you, please apply!

I can't make it past level 2!

This is a great article, raising many valid points around concurrent programming. I can't speak to Ruby, but Python supports, and has never presumed linear programming.

Python has had POSIX threads since at least 1.5.1. The standard library contains a set tools for concurrent programming (see the threading module, queue, etc) and many included libraries are thread-safe.

The GIL's behavior is complex, but even so it's still possible to write performant, multi-threaded code in Python, especially for IO bound tasks. See David's excellent write up: http://www.dabeaz.com/GIL/gilvis/index.html.

Everybody wants the GIL to be removed, and several attempts have been made, but the collateral damage seems just too great at the moment - C extensions, and tons of libraries, frameworks, and programs would need to be re-written at the cost of greater complexity, for questionable performance gains in the average case.

Backwards compatibility is a core philosophy of Python, one which I think makes it a great programming environment. This makes removal of the GIL more a philosophical problem than a technical one. Python 3 has made some progress in removing GIL contention, but it's certainly here to stay for the foreseeable future.

Perhaps Python will be left behind in the future due to these decisions, but given all the work being done, I find it hard to believe any argument claiming that the Python community isn't actively invested in concurrent programming.

Coffee! In Portland it's practically religion. There's at least a dozen microroasters and hundreds of coffee shops. My favorites: Spella (5th and Washington) Stumptown, and Barista (you choose the beans for your drink!)

It's important to encrypt your private key with a passphrase. Use ssh-agent to store the un-encrypted key in memory on login. On OSX 10.5 or greater, this is really easy: http://bit.ly/alDMhp. Make sure to add 'ForwardAgent Yes' to your ssh config, and then never have to type your ssh password again.

ssh tunnels work great for hulu and netflix when travelling abroad. Or so I've heard :)

I used these for a commenting system as well, they're really quite amazing. There's basically three options when storing a tree in a relational database - adjacency lists which are slow to read, nested sets which are slow for writes, and materialized path, which is slow for moving around nodes. It's good to have a fourth option which is straightforward to implement and has excellent performance.
