It's worth pointing out AEMO's demand is for the grid, and residential solar typically does not show up on the grid. OpenNEM[1] uses estimates of residential solar to approximate the full load. [1]: https://opennem.org.

Nice article, thanks. For anyone interested in the topic, I highly recommend Trefethen's Approximation Theory and Approximation Practice. It's approachable, intuitive, and fun while still covering a lot of technical detail.

This is exactly what is already done! On Earth at least. Radio telescopes around the world observe (mostly) quasars to perform geodesy. This is the main method used to measure the Earth Orientation Parameters which is need for keeping GPS&#

PyPy is written in RPython, which can be compiled to C. PyPy itself emits machine instructions like a regular JIT interpreter.

If you're after something lightweight, similar enough to be vim to be useable, and lua built-in checkout vis: https://github.com/martanne/vis The structural regular expressions are also pretty interesting.

Every number has an infinite decimal expansion. 1 = 0.999... 1/2 = 0.49999... etc. In some ways it's a property of the representation, not something intrinsic to the number.

Pi isn't an infinite series, it is just a number. Sure, it can be represented as an infinite series, but so can any number! (Eg. 1 = 0.999999...)

Since Python is an interpreter, it keeps a dictionary/hash table of the local and global variables. These can be accesses by the functions `locals()` and `globals()`. `a = ... ` can be thought of as `locals()["a"] = ...` (alt

The slight curve to usually straight letters like 'v' and 'k' reminds me a bit of of Inconsolata. I really like this touch and makes a monospaced font flow. Is it also using Spiro splines?

A problem I'd like to see a good solution to is selection bias. Unless there is some kind of reward, only people that really care are likely rate something I think Netflix's move might help this. It certainly lowers the cost ratin

3D plots can useful when the data is intrinsically 3D. But forcing a 3D plot on 2D data, like a pie chart, makes it hard for a viewer to develop an intuition for the data.

I'd second the PGFPlots recommendation. Easy to create plots by hand or you can use matlab2tikz (mentioned but dismissed in the article) if you're coming from matlab. I'd also second the latexmk recommendation!

by widdma 10y ago
I found matlabl2tikz to be superior to plot2latex. I did my honours thesis with plot2LaTeX+inkscape and my PhD one with a matlab2tikz, so I've had a fair experience with both. I have created some high quality, complex plots out through

PulseAudio is pretty good these days and typically works out of the box for most need. Per app volume is an amazing feature and switching sinks is a breeze. I often play music on my stereo (mobo sound card) and game audio on some headphones

iTerm2's killer feature that I haven't seen in any Linux terms yet is tmux integration. Being able to treat a remote tmux session like a local terminal session — including tabs, splits and windows — is fantastic.

The story is that Knuth chose '$' to denote math mode because math typesetting at the time was prohibitively expensive.

Yeah, fair enough. On MacTeX or texlive on Arch, it usually takes me a few iterations of `tlmgr install` runs before I have everything I need. "collection-fontsrecommended" is usually the (meta) package I install these days. I wis

LaTeX itself isn't over 2GB. The complete texlive distribution is about that large, but that's everything and the kitchen sink. You can install a small base which comes in ~150mb, then add packages as you need.

Maybe they meant distributes ? Modulo (sort of) distributes over multiplication: (a * b) % c = ((a % c) * (b % c)) % c
