> given that Australia does daylight savings time DST varies by state in Australia. Western Australia (UTC+8) does not observe DST.

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 t…

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 whil…

Yup, and make dirty power more expensive with a carbon tax.

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 …

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

You can enter passthrough mode in Vimium with "i"

True, perhaps the author meant rationals.

I think if he did have mental health problems, like many others in the field, it's now more than ever to raise the point. If he didn't it doesn't hurt to raise the issue, because i…

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…

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...)

This release introduces Project Treble with the goal, I believe, of fixing this exactly this problem.

For contex, Ross Ihaka is one of the original authors of R. This date back to 2008. Also see Ross Ihaka's 2010 paper: https://www.stat.auckland.ac.nz/~ihaka/downloads/JSM-2010.pd..…

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 = ... ` ca…

> Different regions have dramatically different average commute times which don't directly correlate with population. Thus disproving your point. Average commute time is not the de…

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 …

> Not at all! Happiness _is_ correlated to shorter door-to-door time, but higher speed does not equate to shorter times if the distance grows as well. Exactly! This is also related…

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 m…

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 seco…

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 ha…

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 m…

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, sp…
