How to recover lost Python source code if it's still resident in-memory

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

A tutorial on how to get started using glob patterns in your terminal. #writing

Glob Up and Running

To test a glob pattern go over to globtester and play around with creating your own file structure online, it's super easy to get started that way.

If you want to test out a glob pattern in the terminal use echo followed by the pattern, for instance.

echo **/*.js

Everything Wrong With The Withings API

Top Six Things You Need To Know About The Withings API*

*where “you” is probably a developer, or at least a strange user

I should preface this by saying that I got a Withings Smart Body Analyzer for Christmas last year and I’ve been generally happy with it. It purports to be able to take my heart rate through my bare feet and that seems not to work for my physiology, but overall I’m a fan. If if their Wikipedia page is to be believed they are having a pretty rad impact on making the Quantified Self movement more for normal people and they only have 20 full time employees. Also they try hard to use SI units, which I can get behind. Anyway, on to the rant.

I originally called this post “Everything wrong with the Withings API” and I meant it. For every useful field I can extract from their “award winning” app, I have spent an hour screaming at the inconsistencies in their implementation or inexplicable holes in their data

How to download a streaming video with Google Chrome

How to download streaming video

Streaming just means a download that they don't want you to keep. But Chrome's developer tools make it easy to access what's really going on under the hood.

Open Developer Tools

From the page where you want to download some things, go into your chrome menu to open the developer tools. You can either:

1.  (On a mac): Command-option-J
2. (On a PC): Control-alt-J
