DST varies by state in Australia. Western Australia (UTC+8) does not observe DST.

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.

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 Earth Orientation Parameters which is need for keeping GPS/GNSS calibrated.

With it, you can measure distances of several thousand km with a precision on the order of a few millimetres. The problem is that it's really expensive compared to GPS: at each site you need a reasonably size telescope, atomic clock, some serious storage, and a way to ship all the data to a central cluster.

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 it is genuine.

If you suffer from anxiety and/or depression, there is help. Talk to someone. You're not alone, and you don't need to suffer alone.

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.
