You might get unusual errors about Unicode and inability to convert to ASCII. Programs might just crash at random. Those are often simple to fix — all you need is correct locale configuration.
To create a project that other people can use and contribute to, you need to follow a specific directory structure. Moreover, releasing a new version should be as simple and painless as possible. For my projects, I use a template that has the structure already in place, and comes with automation for almost every part of a release.
Recently I was working on some C# and Java code. And along the way, I used Python and Vim to (re)write my code. A small Python script and a 6-keystroke Vim macro did it faster and better than a human would.
Every programmer should learn a good scripting language and use a programmable editor like Vim. Why? Here are two examples, after the break.
You’ve just written a great Python web application. Now, you want to share it with the world. In order to do that, you need a server, and some software to do that for you.
The following is a comprehensive guide on how to accomplish that, on multiple Linux-based operating systems, using nginx and uWSGI Emperor. It doesn’t force you to use any specific web framework — Flask, Django, Pyramid, Bottle will all work. Written for Ubuntu, Debian, Fedora, CentOS and Arch Linux (should be helpful for other systems, too). Now with an Ansible Playbook.
Revision 5 (2017-04-29): Better module specification description, environment variable configuration info
I spent Saturday on rewriting a Flask app in Django. The app in question was Nikola Users, which is a very simple CRUD app. And yet, the Flask code was a mess, full of bugs and vulnerabilities. Eight hours later, I had a fully functional Django app that did more and fixed all problems.
I tested the speed of four static site generators: Nikola, Pelican, Hexo and Octopress, in a clean environment. Spoiler alert: Nikola won.
Disclaimer: author is a developer and user of Nikola. The test environments used were the same for all four generators.
- Nikola v7.6.1, by Roberto Alsina, Chris Warrick and contributors; Python; MIT license
- Pelican v3.6.0, by Alexis Metaireau and contributors; Python; GNU AGPL license
- Hexo v3.1.1, by Tommy Chen and contributors; Node.js; MIT license
- Octopress v2.0, by Brandon Mathis and contributors; Ruby; MIT license (based on Jekyll)
pass is the standard Unix password manager. And I just wrote a slightly friendlier, clickier interface with urwid and Python.
Are you executing a process that takes a long time? Do you want to know that it’s still working while you are in another terminal/making coffee? Do you have a favorite game show tune to play while doing something?
If yes: think is just for you. For more details, read on or hop onto the GitHub page.
A week ago, I was inspired to produce a new projects page for myself. The previous one was a trainwreck with a lot of hacks. Also hosted on GitHub Pages for some reason.
There are multiple ways to write an app in Python. However, not all of them provide your users with the best experience.
One of the problems some people encounter is writing launch scripts. The best way to handle this is the Entry Points mechanism of Setuptools, and a __main__.py file. It’s quite easy to implement. If you’re interested, read on to learn more!
