Distribution Detection

I am working on adding support for building and distributing (via PyPI) Python Wheels with C Extensions to the Python wheel and pip packages. The discussion on Distutils-SIG continues, but I believe it is fairly certain that some effort to correctly identify Linux distributions will need to be made. I've begun efforts to add this support to wheel.

How you can help

If you have a Linux distribution or version of a listed distribution not in this gist, or one of the ones I have not directly verified, I could use the following:

• The contents of /etc/os-release, if it exists

import json
import os


class Settings:
    _config_location = 'config.json'

    def __init__(self):
        if os.path.exists(self._config_location):
            self.__dict__ = json.load(open(self._config_location))

On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.

These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.

dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.

Installation

1. Create a directory under /root, say /root/module-signing, put the three scripts below in there and make them executable: chmod u+x one-time-setup sign-modules dkms-sign-module

Recently, Let's Encrypt launched free wildcard certificates. While this is good news in and of itself, as it removes one of the last remaining reasons for expensive commercial certificates, I've unfortunately seen a lot of people dangerously misunderstand what wildcard certificates are for.

Therefore, in this brief post I'll explain why you probably shouldn't use a wildcard certificate, as it will put your security at risk.

A brief explainer

It's generally pretty poorly understood (and documented!) how TLS ("SSL") works, so let's go through a brief explanation of the parts that are important here.

The general (simplified) idea behind how real-world TLS deployments work, is that you:

# Proof-of-concept of an error- and stop-safe cleanup pattern.

<#
    Note that accepting pipeline input for these functions is not supported
    because per https://gist.github.com/alx9r/f81cf64f50a016edda4e92968bdb9c3b
       * there is no way to ensure cleanup when an upstream command breaks, throws,
         continues, or throws a statement-terminating error, and
       * there is no way to determine from a mid-pipeline command whether an exception
         thrown downstream will cause the end of the invokation or will be swallowed by
         an upstream command.

Parse Microsoft-style CSV data with regex

Background

CSV (comma-separated values) files organise their data by separating them with newlines and commas. If a desired piece of data, say a string of text, itself contains a comma, then this string must be surrounded by double quotes:

5,7,8 -- three values

"5,7",8 -- two values
