Yesterday we noticed that our DB was getting nailed everytime we refreshed the main status screen, which does NOT show the stack trace (which can be VERY large for big jobs). We needed a way to only pull those fields when they were displayed, but at the same time I didn’t want to have a seperate model just to use on the main status screen. https://karlgrz.com/monstermash-flask-zeromq-and-echonest-remix/ Thu, 07 Mar 2013 14:55:27 +0000 https://karlgrz.com/monstermash-flask-zeromq-and-echonest-remix/ Off and on for the past couple of months I’ve been working on a side project using flask, zeromq, and the remix api by echo nest. If you take a look online, there are a lot of excellent guides to introduce you to flask, but not many that dive into something more complex or closer to something that an engineer in more distributed services would need to put together. I’ve seen some great guides on organizing larger applications, but not so much commentary about how the experience was. https://karlgrz.com/a-preview-of-my-silly-little-python-mash-up-generator/ Tue, 29 Jan 2013 06:28:40 +0000 https://karlgrz.com/a-preview-of-my-silly-little-python-mash-up-generator/ So I’ve been working on a little side project web app to get familiar with both flask (a python web microframework) and zeromq (the socket library that acts as a concurrency framework), along with remix from echonest. There was this exchange with Brad from devmynd tonight on twitter. Coupled with the promise of tons of rain from our friendly neighborhood meteorologist, I was inspired to create this unholy amalgamation of mash up nonsense.
