Ogi_UnixNut Re:Why would they do anything else? (673 comments)

Or... you know... hire the best person for the job, not set a goal of having a 50/50 distribution?

Humans are not marbles, we are all unique, all have our strengths and weaknesses, and different ways of thinking.

Hire the right person for the job in hand, don't hire people based on some magical need to have a particular distribution. I really don't get this desire...

NASA Halts Non-ISS Work With Russia Over Ukraine Crisis

Ogi_UnixNut Re:Yes...but no (291 comments)

Lasting peace in Europe? You must have been asleep for the last 25 years.

Bombing, invasion, annexation, partition, suffering, in Europe and abroad, by the hand of NATO.
Your "peace" and general prosperity is built on the blood, death and suffering of others, and don't you forget it.

Personally, I'm happy Russia finally slapped NATO in the face. I was wondering if anyone on this planet had the balls to finally stand up to the bully (Disclaimer, I'm not Russian). Now just to see how this develops, geopolitically.

Will Cameras Replace Sideview Mirrors On Cars In 2018?

Ogi_UnixNut Re:Yes (496 comments)

But why is parallax relevant?

It allows us to judge distances using depth perception, partly because we have two eyes at offsets, and as mentioned earlier, because we can bob our head about to help us get depth cueing.

The only way cameras will come close to being as good as a mirror is if they are 3D cameras and displays, to allow us to judge distances like a mirror, at which point I suspect they will be a lot more expensive than just having a mirror.

(Talk about using a jackhammer to crack a nut. It is always easy to make things complicated. Making something elegantly simple, now that requires serious brain power).

US Spying Costs Boeing Military Jet Deal With Brazil

Ogi_UnixNut Re:Remote control? (439 comments)

If that is their worry, then buying any NATO countries produce would not help them. AFAIK The SAAB Gripens use American engines, avionics and components. Apart from the airframe and the final country of assembly (and some local parts), they are not really making much a difference as far trust of the hardware goes.

If that was the real worry, then you'd have to buy someone elses (probably Russian), but they went out of the race a while ago.

DRM To Be Used In Renault Electric Cars

Ogi_UnixNut Re:DRM not possible in my ride (231 comments)

Funny you mention that, here in the UK, like in most of Europe, cars have DRM already. As such you have to go to "authorized" garages, where they have to reprogram the car computers every time they replace the part. The result being that they can charge you £300 to replace a headlamp.

Classic cars (80's mostly), anyone can do it, and it is cheap (I had my alternator replaced for £35, including parts cost). When I tell people that their jaws drop, as their yearly checkup alone costs a few hundred. That is why I never owned a new car.

The thing is, so many people have realised the same as me now, and have started buying classic cars, that classic car insurance premiums have been increasing rapidly. Car insurance companies have taken to refusing to insure classic cars because of demand, unless you can provide you will not use it as a daily driver (i.e. you can only have a classic if you own a modern, and the classic is only for meets, shows and the occasional drive).

It is becoming harder for me to keep mine to be honest because of the switch, and I wonder if in future there will be a bigger push to restrict people from the classics.

It is interesting to note that the largest rise in classics I've seen corresponds to the years when European new car sales have been flat or shrinking. I suspect causation.

EU To Allow 3G and 4G Connections On Planes

Ogi_UnixNut Re:Well crap... (106 comments)

Yes, I've heard great things about the trains in Europe, however they don't go where I want to, and quite frankly I like driving.

What I would not mind is an extension of what Germany does. There you can drive your car onto a train, and it will do the long boring slog for you (which currently I have to do on highways), and you can drive off at your destination.

However the above is only in Germany (And in Italy, but apparently it doesn't work that well there, and is horrendously expensive), and the high speed rail doesn't go to south/southeast Europe at the moment.

We will see what the future holds, but I am grateful that we actually have alternatives to flying, at least in the core EU.

EU To Allow 3G and 4G Connections On Planes

Ogi_UnixNut Re:Well crap... (106 comments)

No no no... this is the EU doing this, not the US. This means that, after twelve long years, we FINALLY have something about which WE can feel a smug sense of superiority over someone else's airline travel.

Actually, my description of the above is from the EU ;-)

What, you thought we were better? Pretty much everyone here mimicked the US when they introduced their procedure, primarily because they insisted that anyone flying to the USA had to go through this, and it was cheaper to just subject everyone to it then make a whole separate line (and hire separate people) for those traveling to the US.

I pretty much avoid flying in Europe whenever I can. Driving is so much nicer (even if more expensive), plus I can take as much luggage and liquids as I want, without being fondled at the border!

At least we have the option of high speed trains, which I've heard work really well.

Ogi_UnixNut Well crap... (106 comments)

Between the long lines at security, stress, and being fondled and stripped before entry, the only nice thing that was left about flying was the lack of self-important people yakking on their phones throughout the flight... until now.

(hopefully the roaming charges will make absolutely sure nobody does voice calling, but that will depend on how much they charge).

Nearly 1 In 4 Adults Surf the Web While Driving

Ogi_UnixNut Re:Nearly 1 In 4 *American* Adults... (365 comments)

Well... it has less to do with intelligence, then with the driving lessons and tests.

In Germany you tend to not have such incompetence at the wheel. Ditto in the Nordic countries (Finland is where I had a chance to directly observe).

What these countries have in common is a very thorough course in learning to drive, and a lot of time spent on theory (including things about distracted driving). They take driving with the seriousness it deserves.

Quite frankly, I am shocked for what passes for a driving test in the US. It is almost as if driving is a joke, or a game. It was really surprising, considering the US is seen as the worlds biggest Car enthusiast.

One In Five Sun-Like Stars May Have an Earth-Like Planet

Ogi_UnixNut Re:Maybe won't make any difference (142 comments)

if we're so far along the process to colonizing the galaxy, why haven't one of the countless probable civilizations beaten us to it? Or if they had, why is there no trace of their colonies? That's at the core of the Fermi paradox.

Maybe they did, and maybe we are the evidence of it? I can imagine a robotic probe that seeds DNA to hospitable worlds is possible, but that would just be the seeding of life, not any society/culture (and evolutionary pressures may well make the resulting beings look very different to the original). I see no difference to claiming life was brought to this earth by comets, space dust or alien robotic spacecraft (except plausibility, but we will never really know)

I guess it depends on what your goals are as a species, an exact copy of your society (unlikely given the distances and opportunities for information exchange), or just knowing that you are seeding the universe with life that may well develop one day.

Remember, we are only getting started with exploration, only in the last 15 years have we started detecting exoplanets. For all we know some of these exoplanets may bear signs of life, we just can't detect it yet.

Drone-Mounted Laser Weapons Are On the Way

Ogi_UnixNut Re:Nope (116 comments)

Yes, it could be the case that these things may need some time to recharge between blasts, but the advantage is you can have many up in the air at the same time.
So one may only be able to fire every minute, but if you have 20 of them in the air targeting a missile, there is a good chance they will destroy their target.
Unlike manned aircraft, these things have already proven to be able to loiter for hours, so having quite a few in the air at once is possible.

Besides, as energy storage improves, I see no reason why the recharge time won't decrease.

NSA Scraping Buddy Lists and Address Books From Live Internet Traffic

Ogi_UnixNut Re:Isn't it ironic (188 comments)

I ask you, why did we even fight the Cold War, and win it, if we were just going to embrace everything at a later time?

You are making the mistake of assuming that the cold war was fought between lovers of freedom, democracy and individual rights, vs totalitarian all controlling power hungry nut jobs.

Truth of the matter is, both sides were all controlling power-hungry nut jobs, and the cold war was a fight over who gets to be the all-controlling big-daddy of the world.

The problems with the Soviets is that they laid their system bare, they didn't bullshit. This is how life is, these are your rights, if you're a party member, or if you work to benefit the system, you will be rewarded with perks (Nicer houses, cushy jobs , nice car, sometimes even nice German/American ones).
If you don't work for the system, but not actively against it, you are pretty much left to your own devices, live and let live, and all that.
If you work against the system, directly or indirectly (or you piss off someone in power), then you can be arrested, tried, stuck in prison/work camp, or otherwise disappear.

Now the western system, that was far more subtle. They told you you were free, they gave you the impression you were, that you could choose who ruled you, but fundamentally I don't think the systems were different, like so:
If you work for the system, or to its benefits, you are rewarded with more tokens than most (currency) with which you can spend on bigger/nicer houses, or a nice foreign car, etc...
If you ignore the system and go about your daily life, you are pretty much left alone. You earn your keeps, pay your dues, and you live you life.
If you work against the system, directly or indirectly (or just piss off someone high up and well connected), you can be arrested, tried, put in a prison/work camp, or disappeared (via drone or otherwise). For minor misdemeanors they can just destroy you financially, which is another, less radical lever they have against you.

Turns out, when push comes to shove, people are more willing to serve you if you give them the illusion of freedom, choice and power. One ideology was in your face, the other was in the background. Turns out this worked well for a long time, until the internet came around and made knowledge dissipation so easy, that people began to realise what their world really looks like.

For some the revelations were not a surprise, for others it was a confirmation of what they suspected, but some are in shock about it all, and more are in denial about it.

Aussie Company Planning To Use Drones For Textbook Delivery

What makes you think drug smugglers have not been doing this? Since the paparazzi autopilot came out in 03 (and got refined by 06), it has been perfectly possible to build a DIY drone good enough to move a few tens of kilo's across borders.

Considering the profit motive, and lucrative money for any nerds involved, it would not surprise me if they were one of the first non-military users of the tech.

New York Turns Rest Stops Into 'Texting Zones'

Ogi_UnixNut Re:Make cars harder to drive and faster (165 comments)

Funny you should mention that.

When I was growing up, my father seemed to have the complete opposite idea of almost everyone in society. He believed that those who just passed their license should drive fast and powerful cars. I sure didn't get it at the time, and I thought it was a crazy idea, even though I thought it would be cool if he meant it. And happen it did, after I passed my test he gave me a 82 Porsche, and now, I realise exactly what he meant.

To begin with, most kids go through a phase of not taking a car seriously. They throw it around, mess about, etc... like a toy. They take risks because they feel safe, and because they don't quite realise what they are operating. They are very insulated, surrounded by noise insulation, airbags, and all sorts of gadgets and computers "taking care of things". However, this car was different, completely different to the car I did my test and lessons in (which was a bog standard Ford hatchback from the driving school).

That car instilled a respect into me of what exactly a car is capable of. It has no airbags, no traction control, no ABS, no power steering. It had nothing to make you feel safe. You and you alone were in charge of what happened. The car did its best to connect you with the road, and it worked. I felt part of the car, and the road it was on when you were driving. I remember the first time as a new driver. Like most kids, I didn't take it seriously either. Once I floored it for kicks, and the car slammed my back into the seat as the body twisted and the car took off. That was the last time I did that for years. I had never felt that before, and the power actually scared me, as I didn't feel like I had the ability to control it. I realised that I would have to become a far better driver before I could attempt that again.

No ABS meant I had to learn how to brake properly, and keep enough distance to not hit things. It meant I had to pay attention to the road surface and how much grip it had at all times (which was surprisingly easy, as you could feel it through the steering wheel).

No traction control meant that I had to learn how to control the throttle and gear shifting, so as not to wheelspin, or not to lose traction in corners/rain/snow/ice/etc...

It also meant that I pay a lot of attention to the state of my tyres. When you don't have any ECU's managing the traction for you, you can feel when your tyres are getting worn out, or when they lose traction. I'm the only guy I know who does a pre-drive check before going anywhere.

All in all, when driving that car, you are driving it. It requires concentration on the act of driving, nothing less.

It never popped into my head to fiddle with my phone, or read a book/map, or anything else. I guess it is a similar thing to why some motorcyclists say everyone should ride a motorcycle for a year. You just don't get a chance to be distracted. I've had times when I can't even fiddle with the buttons on the radio, and that requires no looking away either.

I've now had that car for years, and I feel it made me a far better driver than if I had just continued driving modern cars.

Indeed when I do drive modern cars, I find myself hating the experience. So much is out of my control, so much "just happens". Initially this made me very on edge, I would even open the windows so I could hear what the car was doing with the road, as I had no other input. You are so isolated from the act of driving the car that you might as well put a blind fold on. I can see why people end up texting or doing other stuff when driving. Hell, even I found the experience mind numbingly boring, and I like driving! I also found it harder to keep awake/alert when doing long distance driving.

It seems modern cars are designed for people who hate driving, probably by people who hate driving. Everything is done to take the "driving" part away. I don't feel like a drive a modern car. I operate it instead. I have two pedals, stop and go, and I point it in the direction I want to go with the steering wheel. The car does the rest.

I can imagine if someone only ever drove modern cars, they would find it tedious and boring, and would want the car manufactures to automate even more of it. You end up in a feedback loop such as we are in, which will eventually end up with self driving cars, just because the majority don't know any better.

Not to say that everyone should be forced into doing the above, I'm sure there are people there who have absolutely no interest in driving a car for the pleasure of driving, but I do think that this is one of those places where we have automated too much away from the person who is supposed to be in control. We are in the dangerous "middle-ground" of car development, where we've automated so much away that getting distracted while driving is trivial, but not automated enough that the driver can be as distracted as they want without it being dangerous.

Key test for Skylon spaceplane engine technology

Ogi_UnixNut Ogi_UnixNut writes  |  about 2 years ago

Ogi_UnixNut writes "The Skylon spaceplane is an ambitious project to develop a single-stage-to-orbit craft that can take off and land like a normal airplane.
Part of this project requires an engine that can work both as a rocket engine and a normal air-breathing engine (a hybrid approach essentially).
This would reduce the amount of oxidizer required to send stuff into space, and could greatly reduce the cost of sending things into space.
Now, some key experimental parts of the engine have been built, and are to be tested in public at the Farnborough Air Show in the UK in July.

For more information, as well an overview of the engine and Skylon project, check out the BBC link."

3D-nanoprinting speed record set by Vienna University

Ogi_UnixNut Ogi_UnixNut writes  |  more than 2 years ago

Ogi_UnixNut writes "A new world speed record for the fastest 3D-printed nano-objects has been claimed by researchers in Austria. The team was able to create sculptures as small as a grain of sand in a fraction of the time than had previously been required, and to demonstrate this process the group created a model of a Formula 1 racing car 0.285mm (0.011in) in length in just over four minutes.

The process itself (two-photon lithography) is well known to the science community, but until now it has been too slow, typically taking days to weeks to generate large 3D structures. This technology offers the prospect of 500x to 1000x speed improvement, and the team are researching applications in 3D printing of bio-compatible matter for use in the medical industry."

'Twisted' waves could boost capacity of wireless spectrum

Ogi_UnixNut Ogi_UnixNut writes  |  more than 2 years ago

Ogi_UnixNut (916982) writes "In Venice, Italy, Physicist's have shown that it is possible to use two beams of incoherent radio waves, transmitted on the same frequency but encoded in two different orbital angular momentum states, to simultaneously transmit two independent radio channels.

In principle this allows the implementation of an infinite number of channels in a given, fixed bandwidth, even without using polarization, multiport or dense coding techniques.

Potentially a boon for congested spectrum problems, although at the moment I suspect it would only work for directional links."
