- “FEniCS is a popular open-source (LGPLv3) computing platform for solving partial differential equations (PDEs). FEniCS enables users to quickly translate scientific models into efficient finite element code. With the high-level Python and C++ interfaces to FEniCS, it is easy to get started, but FEniCS offers also powerful capabilities for more experienced programmers. FEniCS runs on a multitude of platforms ranging from laptops to high-performance clusters.”
- Solves partial differential equations efficiently with a combination of C++ and Python.
- Can be run on a desktop/laptop or deployed to a supercomputer with thousands of parallel processes.
- is a NumFOCUS fiscally supported project
- “makes the implementation of the mathematical formulation of a system of partial differential equations almost seamless.” - Sébastien Brisard
- “FEniCS is in fact a C++ project with a full-featured Python interface. The library itself generates C++ code on-the-fly, that can be called (on-the-fly) from python. It's almost magical... Under the hood, it used to use SWIG, and recently moved to pybind11. I guess the architecture that was set up to achieve this level of automation might be useful in other situations.” - Sébastien Brisard

- Readable regular expressions for Python 3.6 and up.
- It’s a tiny Python library made up of combinators that help you write regular expressions you can read and modify six months down the line.
- Best understood via an example:
>>> hash = text('#')
>>> hexdigit = any_of(in_range('0', '9') + in_range('a', 'f') + in_range('A', 'F'))
>>> hexcolor = (
... beginning_of_line() + hash +
... group(repeated(hexdigit, exactly=6) | repeated(hexdigit, exactly=3)) +
... end_of_line()
... )
>>> str(hexcolor)
'^\\#([a-f0-9]{6}|[a-f0-9]{3})$'
- Has automatic escaping for
[
and\
etc:str(any_of(text("[]"))) → '[\\[\\]]'
- Easily testable / inspectable. Just call
str
on any expression.
- Adrian Rosebrock is focused on teaching OpenCV with Python
- Just a really cool resource of integrating computer vision and Python. Both free and paid resources.
- He had one of the most successful tech learning kickstarters (ever?) on this topic: https://www.kickstarter.com/projects/adrianrosebrock/deep-learning-for-computer-vision-with-python-eboo
- via Ophion Group (on twitter)
- mercurial (hg) source code repository commit history
- August 1990 - June 2012 (cpython 3.3.0 alpha)
- Watch the first minute, then click ahead minute at a time and watch for a few seconds to get the full feel
- Really interesting to see a visual representation of the growth of an open source ecosystem
- Built with Gource: https://gource.io/
- Amazing video of the history gource and its visualization of various projects: https://vimeo.com/15943704
- Who wants to build this for 2012-present?
- Would make an amazing lightning talk!
- Forget the “10x” bit if that term is fighting words. - Brian’s advice
- How about just “ways to improve your effectiveness as a developer”?
- “… there is a clear path to excellence. People aren’t born great developers. They get there through focused, deliberate practice.”
- traits of great developers
- problem solver
- skilled
- mentor/teacher
- excellent learner
- passionate
- traits to avoid:
- incompetent
- arrogant
- uncooperative
- unmotivated
- stubborn
- Focus on your strengths more than your weaknesses
- Pick 1 thing to improve on this week and focus on it relentlessly
- Chaos Engineering is the discipline of experimenting on a distributed system in order to build confidence in the system's capability to withstand turbulent conditions in production.
- Netflix uses the chaos monkey (et. al.) on their systems. Covered on https://talkpython.fm/episodes/show/16/python-at-netflix
- The Chaos Toolkit aims to be the simplest and easiest way
- to explore building, and automating, your own Chaos Engineering Experiments.
- Integrates with Kubernetes, AWS, Google Cloud, Microsoft Azure, etc.
- To give you an idea, here are some things it can do to aws:
- lambda:
delete_function_concurrency
Removes concurrency limit applied to the specified Lambda stop_instance
Stop a single EC2 instance. You may provide an instance id explicitly or, if you only specify the AZ, a random instance will be selected.
- lambda:
