I had a toy project which housed all its data in Postgres and I needed a bit of graph traversal, really basic stuff. I almost prepared some ETL to load the data into neo4j/redisgraph, but then I found out about recursive CTEs in Postgr

Fascinating numbers. Do you know if that 95% number could be brought down by tooling? We have deployed fairly strict code style guides + included some linters and other tools to watch over code quality to reduce these conversations about st

Excellent, I've just finished setting up a Postgres instance on a DO Droplet. I hope they still allow SSH into the instance, so that I can load data directly from there. By the way this comes just a week after AWS Lightsail started off

CppCon has super interesting content. That comes from a person who has written maybe two dozen lines of C++ code, mostly just hello world. E.g. this talk by Matt Godbolt or anything by Chadler Carruth. https://www.youtube.com&#x2

I know we got 11 just today, but I can't wait for 12 already! Rumours about alternative storage systems are extremely exciting, the idea of having a columnar materialised view (just guessing, not sure what the actual implementation wil

Horizontal scaling and/or alternative storage systems (I know, pg can theoretically do both, but...). That and perhaps global consistency aka "sort of but not really defeating the CAP theorem using atomic clocks and all that"

Ace, thanks for elaborating. You could perhaps add a shorter version of this explanation to your README to make it clearer to others as well.

Just clicked around and here's a note from the elastic/eui repo " WARNING While open source, the intended consumers of this repository are Elastic products. Read the FAQ for details." Doesn't instill confidence.

I can highly recommend Joel Grus’ live coding video. He creates a deep learning library only using numpy in an hour and it’s really fun to watch it all come together. https://youtu.be/o64FV-ez6Gw

It's in the Yandex namespace and it is used by said company, which is a huge plus. But if you looked at the development history just a while ago, it was highly dependent on Alexey. It reminds me of Grumpy ( https://github.com

Here's a nice overview of how Facebook migrated their codebase to Python 3. While it's different in nature (server side vs. client side), it's rather interesting. https://www.youtube.com/watch?v=H4SS9yVWJYA

A million times yes. Whenever I teach people anything, I force them to use the tools on problems they actually have. You can solve a lot for Alice and Bob, but I'd rather you solved something for yourself.

1) Learn to do as much in plain Python as possible, focus on lazy evaluation (itertools, yielding, ...), you'll be able to process gigabytes with a tiny memory footprint, deployment will be a breeze etc. 2) Get to know some of the basi

Please add (2014) to the title. As for the book - read it a while ago, it's very good. That's coming from someone who actually trained to be an economist before reading it.

But I don't want to be just snarky. We faced the very same dilemma and solved it in a similar way - we use Apache Spark, which can connect to MongoDB directly. It loads fairly quickly and we can save it to Parquet on S3 directly, the w
