A client had a weird problem with data flowing 10x faster in one direction between two parts of its campus on either side of a road, ~30Y ago...

TL;DR: kinked fibre causing large (NFS) packets to fail frequently in one direction

Bad PIs seem to be a real problem.

Luckily I'm self-funded and with good supervisors, so not a problem that I face!

They should be unless you want to publish one of the things that too many (eg sites) regard as a reasonable secondary security verifier.

Get a single speeding ticket in most jurisdictions in the U.S. and your birthdate is never confidential ever again.

And health records, e.g. prescriptions, as well.

Inherently sexist/misogynist/objectivising the human female form?

Octopus in the UK has tariffs where it basically takes over your system (ie the batteries in particular) and subsumes them into its wider activities, eg:

https://octopus.energy/intelligent-flux-faqs/

We brought down our energy consumption substantially over the years starting not so far from that high figure, including swapping out racks of Sun servers for an RPi or two, and we are now slight net exporters of utility energy and with it roughly zero carbon...

The land-use and EV vs ICE efficiency compound in:

> ... you could drive 70 times as many miles in a solar-powered electric car as you could in one running on biofuels from the same amount of land.

The article notes that the EVs have a lot of storage embedded, so the biofuels to EV problem might be considered mostly a transmission issue!

EVs provide a lot of storage, but people tend to drive during the day and charge at night, so it might actually exacerbate the storage issue. Increasing access to charging stations usable during the day such as in employee parking lots helps, but short term storage is definitely going to need to increase.

I was being slightly tongue-in-cheek, but if we stopped fighting one another and built a planet-circling grid (I have ofc made a modest proposal for a US/Europe interconnector including wind generation along its route) then the issue would become transmission from where electricity is being generated to matching (EV) charging demand.

I mean even then the world is pretty boned when the sun is over the Pacific

You could build some floating megastructures to hold a bunch of solar panels out in the ocean, but making batteries seems a little easier.

Or you could call them interconnectors strung with solar and wind generation.

In any case, if PV is available from somewhere on the globe much of each 24h, and cars are plugged in to recharge then (typical UK cars are parked ~96% of the time), then it's mainly a transmission problem again, maybe?

Browsers already have an early scanner to look ahead for things that it may need to load soon, such as images, and piles of heuristics. Those heuristics are hard in part because many HTML authors don't bother marking up their image dimensions. The lazy attribute helps avoid loading images that the author can be fairly sure will not be in the initial viewport, so is an optimisation hint to override some of those heuristics. So it saves some bandwidth and helps ensure that things above the fold are not fighting things below in the initial viewport construction. So we're about two levels of optimisation in here, but browsers do a reasonable job when fed good img tags anyway.

Nice pure-declarative responsive tweak!

This should be a "Show HN: " to be in line with the guidelines rather than just SPAM, IMHO.
