Certbot is part of EFF’s effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identify of web servers (e.g., is that really Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Let’s Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.

Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate is. Certbot and Let’s Encrypt can automate away the pain and let you turn on and manage HTTPS with simple commands. Using Certbot and Let's Encrypt is free, so there’s no need to arrange payment.

How you use Certbot depends on the configuration of your web server. The best way to get started is to use our interactive guide. It generates instructions based on your configuration settings. In most cases, you’ll need root or administrator access to your web server to run Certbot.

If you’re using a hosted service and don’t have direct access to your web server, you might not be able to use Certbot. Check with your hosting provider for documentation about uploading certificates or using certificates issues by Let’s Encrypt.

Certbot is a fully-featured, extensible client for the Let's Encrypt CA (or any other CA that speaks the ACME protocol) that can automate the tasks of obtaining certificates and configuring webservers to use them. This client runs on Unix-based operating systems.

Hypothesis is a powerful testing library.

It lets you write tests which are parametrized by a source of examples, then generates the simplest examples that make your tests fail. This lets you find more bugs with less work - it's easy to use, stable, and advances the state of the art, so if you're not using Hypothesis to test your project you're missing out.

It works well for both simple and very complex tests - here's a short example:

def test_mean(xs):
    """For any list of numbers, the mean is between the min and the max."""
    mean = sum(xs) / len(xs)
    assert min(xs) <= mean <= max(xs)
Falsifying example: test_mean(xs=[9.9792015476736e+291, 1.7976931348623157e+308])
Traceback (most recent call last):
AssertionError: mean=inf

Falsifying example: test_mean(xs=[])
Traceback (most recent call last):
ZeroDivisionError: division by zero

MultipleFailures: Hypothesis found 2 distinct failures.

Oh, yeah - Hypothesis can find and independently minimise examples for multiple bugs in a single test. Awesome, isn't it!

Hypothesis makes it very easy to define your own strategies for examples, and ships with support for Django, Numpy, Pandas, pytz, as well as most built-in types. It can even work out how to call functions or build your custom objects based on their type annotations!

See for articles, tips, and testimonials; the documentation to get started; or the repo to contribute.

Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle.

The idea is that during a test, a swarm of locusts will attack your website. The behavior of each locust (or test user if you will) is defined by you and the swarming process is monitored from a web UI in real-time. This will help you battle test and identify bottlenecks in your code before letting real users in.

Locust is completely event-based, and therefore it's possible to support thousands of concurrent users on a single machine. In contrast to many other event-based apps it doesn't use callbacks. Instead it uses light-weight processes, through gevent. Each locust swarming your site is actually running inside its own process (or greenlet, to be correct). This allows you to write very expressive scenarios in Python without complicating your code with callbacks.

Mimesis is a fast and easy to use library for Python, which helps generate mock data for a variety of purposes. This data can be particularly useful during software development and testing. For example, it could be used to populate a testing database for a web application (Django, Flask, etc.) with user information such as email addresses, usernames, first names, last names, etc. The library was written with the use of tools from the standard Python library, and therefore, it does not have any side dependencies. Currently the library supports 33 languages and 22 class providers, supplying various data.

Basic Usage:

>>> from mimesis import Person
>>> from mimesis.enums import Gender
>>> person = Person('en')

>>> person.full_name(gender=Gender.FEMALE)
'Antonetta Garrison'

>>> person.occupation()
'Backend Developer'

>>> templates = ['U_d', 'U-d', 'l_d', 'l-d']
>>> for template in templates:
...     person.username(template=template)


You can specify a locale when creating providers and they will return data that is appropriate for the language or country associated with that locale. Mimesis currently includes support for 32 different locales.

Using locales:

>>> import mimesis

>>> en = mimesis.Person('en')
>>> de = mimesis.Person('de')
>>> ic = mimesis.Person('is')

>>> en.full_name()
'Carolin Brady'

>>> de.full_name()
'Sabrina Gutermuth'

>>> ic.full_name()
'Rósa Þórlindsdóttir'

Rather, it aims to complement your existing setup and allow you to extend your CLI debugger as much or as little as you like. If you just want a view of the register contents in a window alongside your debugger, you can do that. If you want to go all out and have something that looks more like OllyDbg, you can do that too.

Supported: Python 2/3

Built-in views are provided for:

  • Registers
  • Disassembly
  • Stack
  • Memory
  • Breakpoints
  • Backtrace

The author's setup looks something like this:

voltron example LLDB

Any debugger command can be split off into a view and highlighted with a specified Pygments lexer:
