Mostly just listening on here, analysing interesting questions elsewhere.

New Zealand's supermarket duopoly means that although there are more than two store brands in many areas, management of pricing, range, suppliers and property are coordinated by Foodstuffs and Woolworths.

I've analysed populations catchments for 797 retail stores, link below!

I write (four-weekly) the Weekend Post's (syndicated) lead arts interview feature. Some highlights include Warren Ellis (https://t.co/XccTliL2sx), Dan Savage (https://t.co/rp818Hwexo), and Bic Runga (https://t.co/UMb31W4EGa

@PoW_Blockspace @JG_moves_NZ We’ve based rates on actual bill structure of several schools including a top 50 high school. As you suggest for the very largest schools refining costs based on contract models would enhance accuracy. We’ve been careful not to overestimate benefits, eg assumed low FiT rates.

[Peter Bisley @pcrb]

We could build 108MW of solar producing 141GWh yearly at schools, with 16% of NZ that learn or work on-site using 96GWh.

Costing $162-216m this would save $18m to $23m yearly, avoid tens of thousands of tonnes CO2, and boost 14,000 construction workers that lost jobs since 2023.

@PoW_Blockspace @JG_moves_NZ We use a single volumetric rate and don’t assume any savings on fixed charges. Modelling at each EDB could improve the precision but we estimate benefits in a range for this reason.

[Peter Bisley @pcrb]

@PoW_Blockspace Both are needed in my view

@JG_moves_NZ Grid scale is great but school generation has excellent alignment with consumption and can be used right at source with no transmission cost and losses

@DanNeidle @Tom29143367 It’s called “broad base low rate”: 15% VAT with basically no exemptions, council property rates are high, corp tax at 28% higher than OECD avg, marginal income tax rate on median worker is relatively low but 10.5% rate applies from first dollar earned, and high alco/tobac duties.

Housing is a pivotal issue in this Saturday’s Australian election. I've produced house price measures based on this year’s newly-drawn electoral boundaries, looking at the most marginal seats, the COVID price surge, and growth rates by party of government.

The existing zoning looks like this:

I've produced a tool that shows the Western Line station catchments interactively, and I've added in the existing zoning for comparison. Link below in the reply!

Auckland Western Line will see substantial time savings from City Rail Link. I've used the latest census, and transport network data, to show the walking and cycling potential to these stations. Active transport has the potential to multiply the impact!

Maps like the one below for all Western Line stations can be viewed here:

I’ve written a new blog post detailing a method of house price measurement for England & Wales that allows detailed, cross-district affordability measurements.

So I think I've found another pretty incredible example of the generalisability of neural network potentials: this is a problem I've been dreaming of tackling for a decade but never felt I had the the tools to get at until now: How do potassium ion channels work. 1/n

These channels are ubiquitous throughout biology they carry potassium ions out of cells with incredible speed and selectivity and are critical for nerve functioning and neuronal firing etc. Despite this we still don't know basic things about them. In fact, debate has gone on for years in top journals about whether water is co-transported with potassium or not.
