I've just posted a related comment. I agree with above. Wings 3D and Blender are pretty good Mayas, though. Agreed on AutoCAD too, although I don't like it, and favor SolveSpace (Windows only) for that sort of stuff. Like I've mentioned, what I can't seem to find is a good (NURBS) surface modeler, like Rhinoceros 3D or Alias.
"This is a shame, because all of the best 3D and 2D tools, other than video, are entrenched in the Linux environment and perform best there."
I don't know of any surface modeler software for Linux that uses NURBS (the state of the art method, mostly) for working with surfaces, like Rhinoceros 3D or Alias do (both Windows only).
Sadly though, Reaper (for Windows only) is the DAW you want to use, not Ardour (Linux) or even Pro Tools (Windows, sort of industry standard for small / amateur projects). You can trust me on that one (because I've used different tools in real projects) or or have a look at a few forum threads to see what others say. No affiliation. It's just better and it makes things easier.
That's totally correct. As far as I know, all detailed design for Osiris (including the power supply I designed while working at INTA) was carried out within the period 1998-2001 (with all the specs done long before that). The flight hardware test campaign was successfully completed sometime in 2001. This would be the equivalent to moving from development to production in the consumer world.
One of the requirements for the power supply I designed was for it to operate in sync with the CCD electronics to minimize the electromagnetic noise (conducted and radiated), 650 kHz, somewhat challenging at the time. I mention this to highlight that an entire spacecraft is a lot noisier than a consumer camera, and this doesn't help high res, high dynamics pictures.
The iPad is very clearly the wrong hardware for the purpose. These days we have much better hardware for the purpose in terms of both suitability and cost than any graphics calculator including Arduino, Raspberry Pi and BeagleBoard and the like. The list is endless and great.
I'd be very interested in a pocket version (that's with no bracelet). I have thin wrists and tend to wear small, light watches or no watch at all. But since all I use to carry stuff around when I leave the house is my pockets (I never carry purses or bags), I like to take very little with me (typically small wallet + key ring + phone), and reducing the phone size by a factor of 4 or 5 would make it a lot more comfortable in my pocket.
I suspect that things work differently here in Spain than they do where you are from, or at least in the house where I was raised. You see, my mum has given me an enormous amount of unconditional love over decades. She used to have a job (despite my dad having one too), do most of the cleaning and cooking, rise 3 children and continue her studies, all at the same time. Despite all this, for years she found time to help me with my homework EVERY DAY. If my other half loves her mum say half so much as I love mine, she won't ask me to consider "letting her move with us", but rather she will kidnap her mum and force her to come live with us as soon as she suspects that will improve HER MUM's quality of life. Because of this, I don't think the term "cost" applies, and the robot doesn't start looking any more attractive.
I think they are targeting the wrong audience here.
We are already surrounded by robots including the washing machine, the Thermomix and many others. Last generation vacuum cleaners can do the whole job for you and the company making the original one is called iRobot.
However, I think that there is correlation between anyone choosing to use whatever robot and his / her age when it first comes out. Microwave ovens for example are generally used by people below 70, because people above that never bothered to figure out about them when they came out. So for this senior robot thing to work, you'll need to sell it to people say 60 years old who still may give a s**t about these things. Problem is, at that age, they don't need it at all yet, so they are not going to buy one just to familiarize themselves. Moreover, when they do need one, in say 16 years time, the model would be a joke compared with the current ones in the market, because these products become obsolete very quickly.
The idea of a 90 year old person choosing to buy or use the thing shown on those pictures seems an unlikely one to me.
In fact I've just listened to the tone and it uses the intervals of a perfect fifth up, followed by an octave up (counting from the first note, D), which are the two most consonant intervals of them all, since their frequencies are strongly present on the first note anyway, in the form of natural harmonics.
Tri-tone as in "melody using 3 tones", not to be confused with the tritone interval
http://en.wikipedia.org/wiki/Tritone
which is considered the most dissonant interval there is in the so called just intonation system.
Play quiet stuff (be it music, noises from nature, white noise, a waterfall, whatever) ON THESE:
http://www.extremeheadphones.com/
Your brain will naturally focus on whatever audio comes from them just like any other headphones... but on top if that you'll get twenty something dB less ambient noise, which is a lot of attenuation, that enables you to play whatever stuff at quite low volume.
After reading plenty of positive reviews and the story about how they were conceived, they are definitely on my shopping list, my intended use is different, though, I'd like to be able to listen to music on while on the subway, pretty noisy in Madrid where I live, in a comfortable way.
..but the car in the pics is a K1 Attack:
http://www.k1-attack.cz/
It's a VERY light car (I'd say around 650 kg), hence the high performance and low consumption.
I have a car (kind of, but still road legal) that weighs 400 kg (430 kg with some fuel), does around 4 sec 0-60 mph (0-100 kph) with just 128 bhp: http://www.locost.es/

4.1 sec is bloody fast actually and in fact you have to be quite skilled to get a figure like that from a car driving yourself (I'm now talking about a manual-gearbox, fuel car), it's not just putting your foot down, you do that and then too suddenly you need to take care of many many things at the same time (changing gears, compensating steering).
By the way, and this applies to fuel, electric whatever car: You don't need to spend big money (Ferrari, Porsche as mentioned by these guys) to get ridiculous performance. I'm the proud owner of a "Locost" kit car which does 0-60 in 3.8 secs and paid about $7500 (5000 actually) for it on the road. Description of these here.
. . 10), 11) or 20) (who cares). Use rechargeable batteries.
You completely miss the point. It is not about growing a tree OR using rechargeable batteries, it's about having a better environment by doing whatever each of us may feel like doing, being it planting trees or using rechargeables or both.
Skin effect is absolutely negligible at 60 Hz, in other words, skin depth is quite big in that freq range. And it's not real skin, OK? Descriptions here and here..
> There is some truth that competition is not always the best way to get things done
In fact, what open source is demonstrating is that the best way to get things done is COOPERATION (open) as oposed to competition (close).
You work for you and the community instead of only you, you get the whole community working for you, magic! Isn't that what societies were meant for in the first place anyway?

That's why ESA (that is, Europe) is developing Galileo, which is a civilian GPS system (also a constellation of satellites).

So I still need a dodgy defrag to keep my disk nicely packed or it finally does like ext2, where you keep it clean just by using it?
I just read "WinFS is on top of NTFS", so this may not be the case..
