Configure GeoIP for iptables

This script configures GeoIP for use with iptables. Installs Linux headers, uses xtables-addons, uses latest db-ip.com database, fixes dependencies, loads xt_geoip module.

Supports colored message using ANSI escape codes. 😎

Run the script as root or with sudo.

Script Functionality

React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

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
