Happy Birthday jose!
Belated happy birthday Jose! Love the blood sausage - in the UK called Black Pudding - absolutely delicious.

The Knuckledragger 3rd Memorial Slow Forum Post
That is absolutely brilliant. I just wish he'd return to his roots in stage acting too - I think he would be totally superb. But I said the same thing about Patrick Stewart when I watched him play Jean Luc Picard; I think my words were "I'd walk over hot coals to see him act in Shakespeare" - and we've now seen him six or seven times on stage, including a superb MacBeth in a studio theatre seating 200. An extract from the film version: In fact, in that same theatre we've tickets to see Ian McKellern play Lear later this year. Can hardly wait.

An uber-late happy birthday!

The Headcase Stax thread
The CMS (stands for Compact Muon Solenoid) on LHC at CERN is pretty tongue in cheek when it comes to the word "compact"

The analog thread.
Absolute madness close to being completed. A fully balanced phono stage, Erno Borbely design that appeared a couple of years ago in Linear audio. Three 19" rack width units. Two independent power supplies in one chassis, Left in another and right in another both fed from shunt regulators. Pass the medication....

Here was me thinking I was retro - and it turns out I'm actually mainstream

What are you listening to Part the Third
Blind Faith. Only one 1969 album with a massively controversial cover. Clapton, Steve Winwood, Ginger Baker and Ric Grech. What a stunning virtuoso album with the best of the best.

The Knuckledragger 3rd Memorial Slow Forum Post
Two or three years ago I took my son to see Clapton and Steve Winwood in Birmingham (UK). Awesome concert. Apparently Crosby, Stills and Nash asked Steve Winwood to be a band member. But he had other commitments and did not really want to anyway, so Neil Young ended up as second choice.

Noise canceling headphones for portable DVD player
I got involved with noise cancellation at one stage US5018203A.pdf In the late 80's noise cancellation was in its infancy. So while I was working on that I found that Dick Rutan's round the world Voyager airplane used noise cancelling phones. So I phoned them up in the Mojave - and instantly got through to Dick Rutan. He told me that they were using an experimental Bose system, but that they broke around ten hours into the 9 day flight. I also had a natty idea for enhancing the sound attenuation of double-glazed windows. The idea was to sense the sound pressure inside the cavity and use a transducer to servo that to zero (or as close to as possible). But a patent search revealed that someone else got there first. But no such system has been made available to my knowledge.

Grahame - where on the planet are you that has god's gift to toast (Marmite) on sale? I thought you could only buy it here in the UK. And does tasty salted pig parts do boneless pork rectums

Case Fans
-ium is an interesting thing though. Titanium, Lithium, Sodium, Calcium, Magnesium, Iridium, Curium etc etc. Without the "i" those would be Titanum, Lithum, Sodum, Calcum, Magnesum, Iridum and Curum, which would be just silly So Aluminium is completely logical

Case Fans
Just picking up on this thread. I've used chassis punches, hole saws and (ugh) forstner bits depending on the size of the hole and thickness of the material. And only on Al. They key thing with hole saws and forstner bits is lots and lots of lube.

RIP someone or another
Apparently the contractor had that block of flats on their website as a selling point for their services. They have since removed it. Someone, or possibly several will be prosecuted for certain. And since this is "social housing" it is managed by a company wholly owned by Kensington council. So heads will also roll in public office too. A litany of corner cutting, incompetence, and not enough money. Currently getting on for a hundred not accounted for, although to date only 17 have been confirmed - the news just gets worse.

Ye Macce Threade
I'm about to irritate everyone by waxing lyrical about "Ye", as in the title of this thread. This goes back to pre-Caxton times, when there was a letter called thorn, written Þ . This had the sound value "th". So "the" would have been written Þe . Now Caxton, back in the 1400's standardised his printing press on the latin alphabet, and so had no way of writing the thorn. So he picked Y as being the equivalent of Þ . So "Ye" is actually just pronounced "the". The thorn, as Birgir will immediately point out, is still a valid letter and sound in Icelandic.

Death toll has risen to 17, and likely to rise significantly further (some floors are still smouldering with local fires still burning). 37 in hospital with 17 in critical care. Astonishingly there seems to be no good data about how many people were in the building.

RIP the 12 confirmed dead in an horrendous fire in a 24 storey block of flats in London. Fire broke out in one flat, and rapidly spread to others. A refurbishment was complete a couple of years ago, including an external cladding, which turned out to be flammable. No sprinklers, single stairwell. Not in a third world country - in London. https://www.theguardian.com/uk-news/2017/jun/14/fire-24-storey-grenfell-tower-block-white-city-latimer-road-london Many dozens in hospital, the rest escaped in night attire.

Top Gear
Good to see his is relatively undamaged after that fearsome crash. I also was not far off on energy storage in the batteries. From the Rimac website, the battery (650V!) is 90kWh capacity. Which is 324MJ, 27% less than my engineering estimate of 450MJ. But it is a bit of a beast. 2.5 seconds to 100km/h, top speed of 355km/h, 1224hp, 1600Nm torque http://www.rimac-automobili.com/en/supercars/concept_one/ Edit Just to put those numbers into context, I have an old early 80's, V12, 5.3 litre Jaguar. That takes 8 seconds to 100km/h, top speed of 250km/h, 350hp, 480Nm torque.

Thank heavens he is OK in a way he wasn't in the rocket car a number of years back. As to what causes the fire - stored energy in batteries. Suppose you have 1000 hp - 740kW. And suppose you can run at that level for ten minutes. Battery stored energy 450MJ. A hand grenade produces about 800kJ. So the stored energy in that supercar batteries is equivalent to 600 hand grenades. Even if that hand-wavey order of magnitude physics shit is wrong by a factor of ten, there is still massively enough energy in the batteries to cause a major fire or explosion. Now, how badly do you want that Tesla?
