Comprehensions in Python the Jedi way

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

Deploying Parse Server on AWS (WIP)

Deploying Parse Server on AWS

Note: this is a work-in-progress and will be updated with more information over the next few days.

Intro

This guide will walk you through deploying your own instance of the open-source Parse Server. This would be a good starting point for testing your existing application to see if the functionality provided by the server is enough for your application, and to potentially plan your migration off the Parse Platform.

This guide will walk you through using Elastic Beanstalk (EB), which is an AWS service similar to Heroku. Why use EB rather than Heroku? Elastic Beanstalk does not lock you into Heroku-specific ways of doing things, is likely cheaper to run your backend on than Heroku, and it integrates with other services that AWS offer (and they offer almost everything one needs to run an application these days).

An example inetd-like socket-activated service. #systemd #inetd #systemd.socket

README

This is an example of a socket-activated per-connection service (which is usually referred to as inetd-like service). A thorough explanation can be found at http://0pointer.de/blog/projects/inetd.html.

Define a socket unit

The key point here is to specify Accept=yes, which will make the socket accept connections (behaving like inetd) and pass only the resulting connection socket to the service handler.

Solution for mysql Warning: Using a password on the command line interface can be insecure
# Let us consider the following typical mysql backup script:
mysqldump --routines --no-data -h $mysqlHost -P $mysqlPort -u $mysqlUser -p$mysqlPassword $database
# It succeeds but stderr will get:
# Warning: Using a password on the command line interface can be insecure.
# You can fix this with the below hack:
credentialsFile=/mysql-credentials.cnf
echo "[client]" > $credentialsFile
echo "user=$mysqlUser" >> $credentialsFile
echo "password=$mysqlPassword" >> $credentialsFile
