Today’s blog post is going to contain fairly advanced Python hackery. We’ll take two functions — one is a wrapper for the other, but also adds some positional arguments. And we’ll change the signature displayed everywhere from the uninformative f(new_arg, *args, **kwargs) to something more appropriate.
In Python, virtual environments are used to isolate projects from each other (if they require different versions of the same library, for example). They let you install and manage packages without administrative privileges, and without conflicting with the system package manager. They also allow to quickly create an environment somewhere else with the same dependencies.
Virtual environments are a crucial tool for any Python developer. And at that, a very simple tool to work with.
Pipenv is a Python packaging tool that does one thing reasonably well — application dependency management. However, it is also plagued by issues, limitations and a break-neck development process. In the past, Pipenv’s promotional material was highly misleading as to its purpose and backers.
In this post, I will explore the problems with Pipenv. Was it really recommended by Python.org? Can everyone — or at least, the vast majority of people — benefit from it?
Gynvael Coldwind is a security researcher at Google, who hosts weekly livestreams about security and programming in Polish and English). As part of the streams, he gives out missions — basically, CTF-style reverse engineering tasks. Yesterday’s mission was about Elvish — I mean Paint — I mean Python programming and bytecode.
Setting up Python is usually simple, but there are some places where newcomers (and experienced users) need to be careful. What versions are there? What’s the difference between Python, CPython, Anaconda, PyPy? Those and many other questions may stump new developers, or people wanting to use Python.
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 7 and Arch Linux (should be helpful for other systems, too). Now with an Ansible Playbook.
Revision 6b (2019-09-29): Use venv instead of virtualenv; CentOS 7 has Python 3.6 now; CentOS 8 current-lack-of-support note; update supported versions list
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.
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.
