I posted this due to the interestingly worded 'honest disclaimer'. The software licence is pretty good too. Sorry for the confusion - the link was originally to the disclaimer, but that and the post title were changed.
simonsquiff··on A New Theory of How Consciousness Evolved
I'd certainly say there is a spectrum of varying human consciousness from fetus>baby>young child>child
simonsquiff··on The strange life of Q-tips, the most bizarre thing people buy
Oh yes - I'm one of those people. Sticking a q-tip in your ear feels soooo good. It's ticklishly, itch scratchingly good. It also feels better the longer you leave it - if I've not used one for a few weeks it's a genuine pleasure.

It's also a common anecdote that having your ear syringed by a professional is one of the most pleasurable non-sexual feelings. So yes, it's a thing. It's definitely a key part of the reason I [mis]use q-tips. I'm surprised by your comment that you had no idea it was seen as pleasurable!

simonsquiff··on Witch Burnings in Papua New Guinea
PNG is an extraordinary place. My father spent a year in the highlands in 1960, in a missionary outpost in a part of the highlands tha only had contact with the outside world about 5 years earlier. He fell in love with the place and the people; I then visited the same a village a couple of years ago, and had what will probably be the trip of a lifetime, with incredible friendly, welcoming and warm people.

The cities however are very edgy, dangerous and of no charm whatsoever.

This article of course is talking about a very ugly and horrific side of the culture, albeit one that flares up once in a while rather than being ever present.

As it discusses, in the highlands the people didn't even know the rest of the world existed until the 20th century. They hardly ever went to the next village. It was extraordinarily isolated. It's also an incredible story, I strongly recommend the (out of print) book First Contact that describes how both the explorers and locals reacted to this incredible moment - all expertly documented, and recent enough that the authors could interview people who remembered it first hand.

The true highlands are not the towns this article discusses. Mount Hagan is a large bustling town with a main airport. It no doubt has much more occurrences of this ugliness, with communities thrown together more and the chaos of large town living.

The villages in the highlands, where I visited, don't have this kind of vibe, though I'm sure sometimes events like this could occur. They have a sense of community that we in the west have lost. For instance, all the children play together in one big bundling group of fun. The 8 year olds, 5 year olds and 3 year olds (with 1 year olds on their hip) all being kids, without parents (let alone a helicopter one) - though any adult might interact if required. When this type of community setting goes wrong you get the 'immune system' response this article describes, but this doesn't paint any of the daily positives when things are normal.

Like the author I'm optimistic that education will make the bad parts a think of the past. But don't think PNG is a country of savages - the highlands that I and my father knew, whilst transitioning in an exceptionally unique way are full of humanity as wonderful as anywhere in this world.

simonsquiff··on Electric Planes Usher in the Second Great Age of Aviation
The original supposition was that electric planes are the future - albeit a future very far way - because electric means no oxygen concerns, which means higher altitude, which increases efficiency and / or speed.

Now, electric doesn't mean battery. Fuel cells, solar, or even hybrid might all play a part. I believe a large proportion of energy consumption is during takeoff - what if you could draw take off power needs from the airfield rather than from the aircraft? What about hybrid - use gas to get to 30,000 feet, then turn on electric to go higher than that? Yes battery energy density is miles away currently, but if we avoid batteries in part, and improve them too, where might things be in 50 years time? The point is we are on the journey with electric planes, and the goal is a good one for reasons stated. Major problems to overcome - absolutely, but this is not a short or medium term prediction. But 'Magical thinking' required, more so than Dyson spheres? That's harsh.

I think Musk said he'd like this to be a far future project for him. He said he's driven by not wanting to go backwards - how space travel was worse than the 60s, as is air travel (no supersonic public aircraft any more). Electric planes - if possible - would be the solution to faster air travel. With Tesla and SpaceX under his belt, he'd certainly got the necessary chops to tackle it.

simonsquiff··on Electric Planes Usher in the Second Great Age of Aviation
I'm not sure it's ignoring everything - as this article states, electric planes exist today, and are improving at a fast rate. Batteries are also improving (thanks to Musk and others), not that electric planes needs to be battery based - fuel cells could be the answer (though presumably these require oxygen so might have altitude issues). So whilst far away, it's an extrapolation from our current position. Nuclear planes don't exist today in any form, and would have major safety concerns no doubt (any accident would be pretty catastrophic)
simonsquiff··on Electric Planes Usher in the Second Great Age of Aviation
I read a piece by Elon Musk, who was saying that electric planes - whilst very far away - are the future of air travel. Why? Because they will allow planes to fly higher - increasing efficiency and speed. Apparently the normal 30,000 feet cruising altitude is not higher because the reduced oxygen levels at higher altitudes impact the gasoline combustion too much. Even at 30,000 feet the air is thick as soup at cruising speed, and that's why planes have not got faster for the last 50 years. Go higher, as electrics could do, and you reduce the air pressure further and could fly faster and more efficiently. Who knows when battery technology will be advanced enough, but it sounds like a goal worth shooting for (as well as the other benefits of noise reduction and environment concerns)
simonsquiff··on The Work We Do While We Sleep
It does, it's the vestigial remnants of whatever makes the baby sleep...
simonsquiff··on Consciousness Began When the Gods Stopped Speaking
This is my issue with the theory - it's very euro centric. Somewhere like Papua New Guinea where the millions of highlanders had no contact with the rest of the world until the 1930s just don't fit the theory. Presumably they'd have to be bicameral before and in a very small period of time full conscious - doesn't sound plausible.
simonsquiff··on Consciousness Began When the Gods Stopped Speaking
There is a must read series on Julian Jaynes's ideas here, the concept of the 'selfish neuron' in particular is fascinating http://www.meltingasphalt.com/series/
simonsquiff··on “Just remove the duck” (2013)
There was a similar story, that I can't now find a source for, of an advertising company that regularly added a 'helicopter' into their customer quotes for video shots. As well as being superfluous it was massively expensive. So the customers say 'we don't need a helicopter', strike that out and feel good that they've done their cost cutting. The rest of the plan makes it through unscathed.
simonsquiff··on The Mythology of Dog Years
Can anyone explain why dogs (amongst others) age so much faster than humans? A 10 year old dog will be grey and have other visible aging signs, whilst we're still youthful. What is the difference? Are dogs cells dividing at a faster rate than ours, and if so why are they doing that? Presumably the answer gives us insight into the aging process, but I've not been able to find answers in some casual browsing.

Incredible man.

simonsquiff··on CityMapper – Point to Point City Directions
CityMapper has the most hilarious release notes I've ever read. I love getting an app updated - not because of the (awesome) new stuff they keep adding - but because I'm guaranteed a cracking read. It's interesting how writing in such a human voice builds positivity towards the app - I do think it's part of why I rate it so highly. It makes you want for a feature where you can find where the dev team are to have a pint with them...
simonsquiff··on Tesla Motors plans to debut cheaper car in early 2015 (2013)
The environmental stuff is actually just the icing on the cake - EVs have a number of advantages over internal combustion and the disadvantages keep getting smaller.

-awesome acceleration due to instant torque and no gearbox

-amazing handling due to low centre of gravity (heavy batteries at the bottom)

-quieter

-minimal servicing / repair costs due to much simpler drive train with fewer moving parts and no fluid

-more internal space (no crank shaft etc - especially in the back row this makes the middle seat so much more comfortable without a big bulge between your feet)

-more external space (e.g the Tesla S has a front trunk (frunk) where the engine normally is)

-safety factor - extra crumple space with the frunk and no engine to go into your legs in front on collision

-cheaper to run especially in high gas cost areas like Europe

-some areas have perks like using the HOV or bus lane

-convenience factor of 'filling up' at home

The environmental stuff is all goodness (and other responses have illustrated how this still holds even in coal dominated areas) but for many is not the driving factor.

Obviously EVs are not for everyone. My analogy is that they are like SSDs - better in every way except size (range) and cost, and therefore not viable for some...but that will rapidly change as the technology moves on.

simonsquiff··on A New—and Reversible—Cause of Aging
Thanks - germ cells was the key term I was missing, this section on the germline on Wikipedia answers my original question:

Germline cells are immortal, in the sense that they have reproduced indefinitely since the beginning of life. This is largely due to the activity of the enzyme known as telomerase. This enzyme extends the telomeres of the chromosome, preventing chromosome fusions and other negative effects of shortened telomeres. Most somatic cells, by comparison, can only divide around 30-50 times according to the Hayflick limit. Certain somatic cells, known as stem cells, also express telomerase and are potentially immortal.

simonsquiff··on A New—and Reversible—Cause of Aging
One thing I'd really like to understand re: ageing is why a newborn is essentially 'reset' from an ageing perspective. I appreciate that egg cells aren't constantly dividing during a mothers life but they are still a product of division and contain DNA that can suffer from time based mutations. So if aging is due to mistakes accumulated during either divisions or time then why are children born young? I don't think this is as simple as non-viable embryos are miscarried, there must be something different in the formation of embryos that means they don't carry the aging of their parents...and what clue does that give to cure aging?
simonsquiff··on Tesla Gigafactory [pdf]
I'm a massive fan of Tesla and Musk, a Tesla shareholder from the IPO and definitely support the gigafactory but this is a surprisingly poor presentation. It doesn't layout the need for it, nor what advantage it will give Telsa (other than an unclear 30% cost reduction - compared to today or the rest of the market in 2017?); what is their market - all Tesla, other electric vehicles, solar storage etc. It's surprisingly sparce of detail for such a bold, punchy move.
simonsquiff··on The most expensive e-book
I don't know if this is the case for this book, but really interesting article about how some items on Amazon can get outrageous prices

simonsquiff··on IE7 users, we need to talk…
We also make software for healthcare customers, and asked the same question re: IE7 support internally. Sadly our stats show that IE7 usage for our clients is at 59%! Down from a peak at 81% but still crazily high. We're hoping the April no support for XP deadline will change things but sadly IE7 is far from dead in UK healthcare.
simonsquiff··on People Don’t Actually Like Creativity
Reminds me of Shanks law: "Because people understand by finding in their memories the closest possible match to what they are hearing and use that match as the basis of comprehension, any new idea will be treated as a variant of something the listener has already thought of or heard. Agreement with a new idea means a listener has already had a similar thought and well appreciates that the speaker has recognized his idea. Disagreement means the opposite. Really new ideas are incomprehensible. The good news is that for some people, failure to comprehend is the beginning of understanding. For most, of course, it is the beginning of dismissal."
simonsquiff··on Why Cruise Ships are My Favorite Remote Work Location
Cruise ships are also an amazing alternative to nursing homes.

I did some work for p&o cruises, on a ship that focused on round the world trips. These was one old lady there in her 80s who had swapped a nursing home for the ship - and had been there for 3 years or so. The food was incredible, she had diffent company every night due to other guests coming and going, was treated like royalty by the crew (unlike normal nursing home residents), and had an onboard doctor and nurse when needed. And all this was cheaper than any nursing home. Inspired idea.

simonsquiff··on Nikola Tesla Pitching Silicon Valley VCs [video]
It saddens me that this is the current top comment (to me it's a good example of what PG was complaining about) - this video is a comment on VCs, not on Tesla. Tesla is just the straight man. But the top comment is nit picking on how Tesla isn't really like this pastiche. I'm much more interested in how this does or doesn't reflect the reality of VCs.
simonsquiff··on Farmers, Elephants, and Bees
Yes you are right. I was really just qualifying the original post about her getting rich. On reflection we're all making the same point that she's getting recognition and the programme is getting financial signalling of a job well done, which is great.
simonsquiff··on Farmers, Elephants, and Bees
Yes but she said in that article that the money will go towards expanding the programme:

'The recognition and financial support will enable us to expand our vital research work and protect many more rural farming families from elephant invasions.'

I was friends at university with Lucy - she's amazing and the success and expansion of this work will definitely be her main motivator. She's doing it because she adores elephants and spending the money on protecting even more of them will be her main priority.

Like all 'overnight successes' (she's been working on this for over 10 years) it's the result of many years of tough grind and convincing skeptical people you have a viable idea. It's great to she's getting the recognition she deserves.

simonsquiff··on Introduction to Position Based Fluids
If you have an iPad I highly recommend getting LiquidSketch. It's a great puzzler about getting pools of liquid into the right place, and the liquid effect is stunning. It moves exactly as expected, has surface tension, splits and recombines etc - but the really stunning element is colour mixing. When two groups of different colours combine the mixing of them is just utter convincing, and beautiful. Amazing how this was all done on a lowly iPad.
simonsquiff··on American airports do not rank in Top of the world
Yes, but there was general outrage at the terrible queues at Heathrow - e.g. see http://www.bbc.co.uk/news/uk-18672286 it was raised in Parliament even, everyone said it was unacceptable and it was then fixed. Is the poor service in the US seen as a problem that's being sorted? Or just accepted?
simonsquiff··on Why my startup failed
There are already quite a few products that do exactly that. I work for one of those companies - we specialise in nurse scheduling (though also cover doctors and other healthcare staff), and have systems that both manage the hospital's demand (and using their own permanent and temp nurses), and systems for agencies to manage their 'inventory' to fill the gaps. You're right that it's a massive problem and therefore there is a good market here. The full on marketplace idea is also starting to be a possibility but isn't really a big deal yet.

It's also (unsurprisingly) really complex and I'm sure very far from their wine marketplace technology!

simonsquiff··on There is no better battery (2008)
Tesla, who presumably know a fair bit about this, say that battery energy density has been improving at a rate of 7-8% a year. http://www.eetimes.com/electronics-news/4370061/World-on-cus...
