    I've been working with Apache Kafka for over 7 years. I inevitably find myself doing the same set of activities while I'm developing or working with someone else's system. Here's a set of Kafka productivity hacks for doing a few things way faster than you're probably doing them now. 🔥

Show me all my Kafka topics and their partitions, replicas, and consumers
Show me the contents of a topic
Create a Kafka topic
Produce messages to a Kafka topic
Validate the schema of messages before producing to a topic
Do all of this at a distance

                sed maze solver
              
          
    Usage

sed -E -f solver.sed input where input is a file containing the maze.
For best results, resize your terminal to match the height of the maze. To disable animations, delete the lines containing p.
Maze format

The solver assumes the following:

The maze only contains the characters # \nSE
Every line has the same number of characters
There is only one start (S) and end (E)

    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


## Makefile
all:

	rm boundary.topojson;
	mapshaper -i ~/Downloads/cb_2015_us_nation_5m/cb_2015_us_nation_5m.shp name=boundary -clip bbox=-126,23,-65,50 -filter-slivers min-area=700000000 -lines -simplify dp 5% -o format=topojson boundary.topojson;

Suppose you're opening an issue and there's a lot noisey logs that may be useful.
Rather than wrecking readability, wrap it in a <details> tag!
