It's a phone with a peel, but you'll have to wait a bit more for retro Nokia

Re: We already 'ave one

I carry an Android device (normally switched off) for when I want to browse my RSS feeds. That is what the hotspot is for.

We already 'ave one

I've had one since mid July, bought online from a UK supplier. It's not tied to a UK network but I live in Ireland.

There are a few silly UI bugs in the shipped software but the update is pretty good. It makes a great wifi hotspot and the audio quality is lightyears ahead of any smartphone.

Sorry, Neil Armstrong. Boffins say you may not have been first life-form to set foot on the Moon

This underlines the point that, if the Moon were suddenly provided with atmosphere and oceans, they would last millions of years. SF talks of terraforming places like Mars and even Venus, but misses our nearest neighbour!

A few years of cometary bombardment, some blue-green algae and another continent's worth of land.

Mine's the one with the attached wings - because on a terraformed Moon, human-powered flight would be easy!

LLVM contributor hits breakpoint, quits citing inclusivity intolerance

Re: "... promoting diversity."

You may have more luck by explaining it in their language. The key concept is "intersectionality," which explains that people are privileged and/or unprivileged for various reasons, which may intersect in any individual.

In other words, you might be privileged for being white while being unprivileged for having the wrong social background. Or disability, or health issues, or politics, or whatever.

It's a powerful idea, not least because it prevents the very "white is always wrong" scenario you describe.

Creaking Chromebooks getting Meltdown protection soon

Re: Creaking Chromebooks NOT

My Samsung Chromebook 2 (quad-core ARM) does typesetting (LaTEX) and cover art (Gimp) -- but I use Ubuntu with Crouton.

Alternatively it'll do development work (C/GTK application) just fine.

It also does it for 14 hours without a recharge.

Fermi famously asked: 'Where is everybody?' Probably dead, says renewed Drake equation

The Moon might not be big enough. Each pole of a 1/4 wave dipole is going to be 1500km long -- a little less than the Moon's radius. I suspect diffraction would mean the Moon wouldn't be a terribly good shield for 50Hz signals.

Henry Hallan

The frequencies with the strongest transmission from Earth are 50Hz and 60Hz. And no, they are not modulated with "I love Lucy" or any such.

When I was studying electrical engineering along with electronics, I was told that the difference was that, in electrical engineering, anything less than 10kW was noise. Now that may be a small exaggeration, but not a large one: electrical transmission losses on this planet run into megawatts or more, and much of that should be detectable at a distance.

Compared to that telecoms transmissions are insignificant.

Global race for 5G heats up with latest US Congress bill

Re: They only need smaller cells for higher frequencies

The big selling point for 5G is not bandwidth, it is latency. Low latency is how 5G is supposed to allow control of devices (e.g. cars, robots) in real time. To obtain high latency short symbols are needed.

The problem with short symbols is that they are susceptible to multipath distortion. And, for all the promise of technologies like MIMO and beam-steering, the best way to fix multipath distortion is to shorten the path length. That is, to have smaller cells.

Carrier frequency doesn't change that.

Oh honey! Oxfordshire abuzz with reports of a MEEELLION bees stolen

Re: I'm surprised this doesn't happen more often

The issue isn't glyphosates that are the problem, it's neonicotinoids. In other words, insecticides not herbicides.

Beekeepers don't want to take away your RoundUp. Calm down, eh?

Now you've calmed down, Monsanto still produce neonicotinoid insecticides, so they certainly do share the blame. But we still don't want to take away your RoundUp.

UK.gov calls on the Big Man – GOD – to boost rural broadband

Re: Good stuff but a sticking plaster fix ...

The "recent Toty think tank" appears not to have noticed that the UK has a population density 15x that of New Zealand. The pressure on prices may be upward, rather than downward -- which may turn out to be good for the rural economy (with or without broadband.)

Samsung abandons Chromebooks, laptops, PCs in Europe

Re: Where to buy?

Dabs didn't even have stock of Chromebooks. I had a Chromebook 2 on order since July -- no stock. If this was about customers they'd have made more effort to provide product to customers.
