Setting up Emacs for Python development

  • Ubuntu packages to install: emacs autocutsel texinfo git mercurial (git and texinfo are required by el-get; mercurial is required to install pymacs)
  • To set the font size for just this session: press M-: and then type (set-face-attribute 'default nil :height 100) (taken from stack overflow)

Python notes

Installing Emacs on Ubuntu and Python in 2017

  • The aim is to use python3 and virtualenv for python development.
  • sudo apt install emacs25-lucid python-pip python3-dev
  • Install elpy

Which programming language for my Disaggregation system? Matlab versus Python; Graphical Models.

Over the course of my PhD, I intend to write a smart meter disaggregation system.  Maybe this system will end up as a web service; maybe not.  At the very least, it will need to play nicely with existing web services like Pachube.  I've been wondering which language(s) I should use to build my system.  My current answer to this question is to write a complete prototype of the "backend" in Python, with the front-end written in JavaScript, HTML5 and SVG.  It's likely that parts of the "backend" will run rather slowly in Python; but luckily it's easy to get Python to play well with C++ code, so I'd plan to re-write computationally intensive sections in C++.

My initial plan was to use Matlab.  But after writing several thousand lines of Matlab, I couldn't help but feel uncomfortable with it.  There are some seriously ugly bits of the language; and in general it has a rather "hacked together" feel to it.  It turns out I'm not the only one who feels uncomfortable with Matlab: there's a blog called "Abandon MATLAB" with gems like "[Mathworks] even updated the docs for “getframe” to clarify that you need to turn off the fucking screen saver and walk away from the computer like it’s 1992.".  One especially interesting post in "Abandon MATLAB" links to the results of a survey which compares attitudes to MATLAB to attitudes to Python.  Basically, I feel content that I wasn't completely crazy to abandon Matlab in favor of Python and C++.  I'll admit that I'm struggling a bit to wrap my head around JavaScript but I'm getting there with the help of Douglas Crockford's excellent book "JavaScript: The Good Parts".
