Comment 'The creative community' rubs me the wrong way (Score 2) 124

They've been pushing this, C. P. Snow Two Cultures-style, for some time now. Codifying the meaning of 'creative' to film, music...whatever. This coercion of language use is all a bit Eloi vs Morlocks for my liking.

It's not true. And I say that as someone who plays and writes music too. Toolmaking can be creative. Software design can be creative. I'm less well versed in physical industrial processes but I'd be more than willing to bet that there's creativity going on there too. On the other hand, acting is only sometimes creative as well, music often written to a formula...these 'creative industries' are often not very creative. And they often don't create, they use the output of some tools they were given.

I hate the language. I'm clearly not saying that all film making or music is bereft of creativity. I'm more saying that creativity as a word shouldn't be relegated and codified in this monstrously industrialised and high-handed manner so dismissive of everyone else.

I feel you need to elaborate a little further on that. The book lays out sources, equations and testable hypothesis. Interestingly it rarely suggests actual policy. Page 5 of the Motivations sections also laws out why - it is as scathing of campaigners as it is of incumbents.

That aspects are outdated 17 years after its last update does not surprise me. That it is fundamentally incorrect however...given the sources and calculations, I think you'll need a to provide a little more reasoning than "you should fee bad" (sic.).

Comment Retrofuturism worth reading (Score 2, Interesting) 84

As someone who has had a strong interest in this area for a while now, not professionally - just following along, it's been fascinating to watch almost every single prediction from the 1990s UK government advisor come true. These recommendations were, in 2015 this was put up as a web site - Sustainable Energy - without the hot air. This is not a political book, the "without the hot air" bit alludes to that. This is a quantitative book with the maths to back up all assumptions and recommendations.

In it, David McKay makes comments about future energy mix. If you look at the full PDF, the idea of a cable from northern Africa to elsewhere is explored starting page 178. Bear in mind this book was written late 90s/early 2000s with the last revision being 2008 (the author has sadly passed). Generating from Morocco appears on page 181.

Thoroughly good read and I recommend it to anyone interested in the mechanics and figures behind energy transitions. Clearly some will now be outdated...but it's surprising how little. A lot of what he suggested is now unfolding.

Comment Re:The bottle was leaking for years (Score 1) 127

But what I'm saying is that's all vocational. Computer science is basic information theory, patterns, HCI...all of that kind of thing. I'm a graduate of Comp. Sci myself, though in the UK from 1992. During that time we were taught a programming language as an abstract for various concepts (I was taught ADA, for instance) but it was assumed you would go and teach yourself any language you were interested in. I self-taught myself C for instance.

What you seem to be looking for isn't Computer Science grads, it's programmers. From your description I don't think you'd care if they new Huffman's Information Theory or deep graph theory, but would care if they didn't know Javascript. And this is what I mean - that's not a Computer Science thing, that's vocational

I think that's an industry fault rather than yours for instance. I think pushing Computer Science as the name but turning out average programming people is an educational failure.

I hate to be blunt, but what has any of that got to do with Computer Science? This is the problem. To quote Dijkstra - "Computer science is as much about computers as astronomy is about telescopes".

People wanting vocational programming degrees or courses should get them. Computer science is not about teaching Angular. And from my own observation over the years, I can clearly remember the first time I interviewed a programmer who clearly had no idea how a computer worked, or any of the theory behind one. They just knew syntax to type in - that was all. Came as a shock to me at the time, but it's decades ago now and I'm more used to it sadly.

Comment Use case for battery swap (Score 1) 70

I think the use case for battery swap is to support a kind of "power-by-the-hour" battery warranty akin to the arrangement airlines have with the jet-engine manufacturers.

If there was a way to replace the battery that didn't require hundreds of dollars in labor fees, an electric vehicle owner wouldn't have to worry about the unexpected expense of a battery wearing out. The motorist would "lease" the battery, essentially pay a subscription fee for the use of the battery, receiving a replacement when warranted.

The way this would work is that the software on the car would record how much wear-and-tear your driving put on the battery in terms of time, mileage, rates of charging and peak rates of discharge along with time spent at different state-of-charge, much like a jet engine warranty is for a certain number of bringing-the-engine-to-takeoff power "cycles" along with a "rating" applied to the engine as to what constitutes full power in all but emergencies. To make this transparent to the motorist, the system could display the amount of use put on the battery and remaining life.

The key to this battery lease arrangement is that it is relatively simple to exchange the battery. You would not be doing battery exchanges for increase range--that would open the can of worms of exchanging your relatively new battery for a battery someone had "beat on.". The exchange in this leasing arrangement also may give you a reconditioned used battery, but you are paying for "drive cycles" and are not put at financial risk if the battery you receive cannot complete the warranted drive cycles.

On exactly what the detector is capable of detecting. If they're looking, at any point, for radio waves, then I'd start there. Do the radio waves correspond to the absorption (and therefore emission) band for any molecule or chemical bond that is likely to arise in the ice?

This is so basic that I'm thinking that if this was remotely plausible, they'd have already thought of it. This is too junior to miss. Ergo, the detector isn't looking for radio waves (which seems the most likely, given it's a particle detector, not a radio telescope), or nothing obvious exists at that frequency (which is only a meaningful answer if, indeed, it is a radio telescope).

So, the question is, what precisely does the detector actually detect?
