You need to state your premise to enable a reasonable discussion. I've been talking about energy or fuel efficency when it comes to public transport (I see you don't have any return for this, because the facts are indesputible). H

You're joking, right? Passenger capacity is part of the design of air travel. Even so, a plane could be at 1/3rd capacity before it's less efficient than a singly-occupied car. Trains are largely a relic of the Industrial Rev

And Linus was given a hard time because he gets a bit shouty in emails. The absolute double standard of how we know and accept that the upper layer of our society, encompassing almost anyone who has sufficient wealth and/or power, is p

Edit: Now you've clarified your question. There's nothing special about HSR when considering fuel (or energy) efficiency, except that it's probably less efficient over all due to increased air drag, and that it needs very par

So does Claude provide all of the value to those billable hours?

It varies so much depending on passenger occupancy rates. Planes tend to run near 100%, and cars (at least in the US, although I'm sure other countries aren't much better) at near 20%. Assuming 1mpg for the entire train, it needs

CREE offer a variety of LED types with efficiencies 150lm/w (eg CMB, XT-E), up to 230lm/w (eg, 5050). While 100lm/w is typical for domestic LED lighting, it's going to cause problems when the total power is several order

Aerodynamic drag accounts for more energy losses than tyre friction (and tyre friction can be relatively easily changed with tyre pressure or tyre type).

~100 lumens per watt is rather poor, especially given the cost. It's the same as a standard LED lightbulb, and that includes the miniature AC voltage converter. 150lm/w would make it at least a cut above domestic lightbulbs. 200lm

Modern jetliners get a higher miles per gallon per seat than most US (ICE) cars. They easily beat any ICE car with a single occupant in miles per gallon equivalent. If you want to minimise fuel usage and can't find someone to share wit

I did something similar, but then found I almost never needed the EDC items I'd split out from my phone (for me, camera, torch, audio player and notepad). Some of those are in my rucksac for longer trips out of the house. Audio players

There's another benefit - you don't have to keep refactoring to keep up with "progress"!

That might be true (although you do add in the mess of web frameworks), but I strongly believe that resource usage must factor into these calculations too. It's a net negative to end users if you can develop an app a bit quicker but re

I've been saying this for a while. WW3 is already over and we lost, we just haven't noticed yet. It was fought against the West (primarily the US) using their own tools and ideologies.

Just because the idea of F/OSS software is/was relatively radical and a certain type of political act when applied in certain situations, does not mean that it necessarily needs to concern itself with any other political act. Afte

The guy seems very upset about something, but it's really unclear what exactly that is. He talks about a crossroads and the loss of democracy - is this about the EU re-aligning itself away from the US and towards China?

Or a signal that Amazon has reached the required level of incumbency that it doesn't need to worry about speed any more.

>an explosion of software in small and midsize companies For me, that is nightmare fuel. We already have too much software! And it's all one framework or host app version update away from failure.

China already has one (if we're insisting on solar power generation) - 700,000 sq. mi of desert. It's also not just aesthetic - flat terrain is just so much more practical.

A modern F150 doesn't have "max utility". It's for site foremen and driving to Walmart.

Given the vast amount of flat, well-lit terrain within the borders of China, it should be clear that the pictured projects (and the other "blanket a mountain in solar panels" projects that are easily discoverable) are not about th

I find the idea of blanketing mountainous wilderness in relatively short-lived e-waste just awful. Surely there are much better terrains for solar panels?

Not much money * quite a lot of people = not very much money (this holds true for all of the other times this idea has been suggested, too). And this does not take into account the various fees, taxes etc, that will be removed before any mo

That is an interesting precedent. However, Ukraine is not a breakaway state from an existing EU member state (or a state which has been in the EU). There are numerous regions in the EU on a similar path, and none have yet succeeded (includi

The EU has not yet set a precedent for allowing breakaway states into full membership, so it's far from a given that an independent Scotland would be able to rejoin the EU. Scotland is of enormous strategic importance due to its locati

Thin in form factor only! Phones and tablets represent the cutting edge of what humanity can mass-manufacture, and prices and difficulties are only going up.

These supply chains have very non-linear responses. Relatively small fluctuations in demand can have enormous effects on prices and leadtimes.

It's a one-way journey, unless we can adapt quickly enough to a drastic reduction in the general availability of compute power. IMO, our reliance on bloated tech is an existential risk, and reverting to some reasonable baseline needs a
