Boffins who stare at goats: I do believe they’re shrinking

Rubbish

They claim that the region became 3-4°C warmer during the 30 years of the study If you can't smell a rat then there is no hope for you.

This is what I love about FF - it's so customisable because even when Mozilla cock up there is someone out there to fix it with an add-on.

Classic Theme Restorer Add-on

I refused to 'upgrade' for the same reason so was stuck on v28.0. Then something weird happened and FF upgraded to v32.03 even though I didn't have it set to. I hate the UI so went about trying to change it. This add-on put everything back just as I had it - it's brilliant.

None of that australis nonsense for me.

City hidden beneath England's Stonehenge had HUMAN ABATTOIR. And a pub

Re: Wonder where they get their data

Probably from digging a hole in the ground and finding artefacts such as flints used for cutting along with human remains that show signs of butchery/cutting.

Blighty in SPAAAACE: Brit-built satellite films the Earth

Astrium (formerly Matra Marconi Space) has been building payloads for decades in plants at Stevenage and Portsmouth. I used to work for them. Some of us used to etch our names/signatures into the extruded aluminium alloy wave guides using a vibro-etching pen, so for example, if your satellite dish is pointed at Astra 2B for the telly, somewhere up there is my signature floating in the void!

'CAPTAIN CYBORG': The wild-eyed prof behind 'machines have become human' claims

Kevin Warwick has the most unbelievable boring, monotone Brummie accent you could possibly imagine. I was interested in one of the Royal Institution Christmas lectures a good few years ago (2000), but after listening to him for 15 minutes I gained a very strong and strange urge to throttle myself in order to alleviate the suffering.

I can't imagine what it must be like to have to sit through his lectures.

Cheap 3D printer works with steel

Old Technology ;)

This is called Shaped Metal Deposition or Near Net Metal Deposition and isn't 3D printing in the usual sense. I was evaluating this technology 10 years ago for Rolls Royce because they were looking to produce aircraft engine components, mainly casings, from Ti 6/4 alloy using this method.

Casings are usually cast and therefore suffer from all of the usual reduced material properties. By using this method of building up weld metal you produce a casing that has improved mechanical properties, akin to traditional manufacturing methods, but with much less (expensive) machining and waste to produce the finished component.

This method also reduces lead times and designs can be changed without much increased cost.

The surface produced is quite pretty and unique in Ti 6/4 - it's a kind of golden colour with lots of hues of purple and blue throughout with a large grain pattern amongst the lines of build up. I had some cuff-links made from some of the left over material!

Pics of test boxes using this method and close-up of surface.
