  1. Re:What about languages? on Your Tech Skills Have a Two Year Half-Life · · Score: 1

    Knowing C, and knowing C well is an independent skill of graphics programming, version control methods etc. Knowing C++ even moderately well is a skill that takes years and years of mistakes, and mastering it is hugely valuable, regardless of your other skills.

    Yes, there are tons of IT and programming related skills and knowledge of particular technologies which become relevant and irrelevant in even shorter cycles than 2 years, but a ton of fundamentals have not changed in years.

    Regexp and unix shells are as useful as ever. And a lot of people programming 8-bit MCU will go through their highly productive careers without ever worrying about scalability of node.js or some other fad like that.

    This is not to say that learning new stuff and keeping abreast with new tech developments is worthless, quite the contrary. The wider your knowledge the better. But it's important to distinguish core skills from fads, and make your in-depth learning investments accordingly. For a lot of technologies, a 10-minute rapid fire quick start video from the next charismatic conference speaker is all you will ever seriously need to hear about.

  3. Re:My grandfather made one of these... on Robot Walks Like a Human, Requires No Power · · Score: 4, Informative

    No kidding. A random article from 2005
    http://www.world-science.net/othernews/050217_robotfrm.htm
    But researchers at Cornell University in New York State, the Massachusetts Institute of Technology (MIT) and Holland’s Delft University of Technology have built robots that seem to more closely mimic the human gait -- and the Cornell robot matches human efficiency, their designers say. The researchers’ inspiration: simple walking toys that fascinated children in the 19th century.
    ....
    Researchers at each of the three universities have built walking robots, differing slightly but based on the same principle. They are an extension of several years of research into “passive-dynamic walkers” that walk down a shallow slope, very much like simple walking toys that have been around since the 1800s and developed more scientifically starting in 1988.

  4. Hobby level is fast progressing on Hobby Humanoid Robot KHR3HV Rides Bike At 10k/h · · Score: 1

    This is awesome. Just a few years ago, it took Toyota research to put this little guy together : http://www.youtube.com/watch?v=VDm22U_teoQ And it used active internal gyro wheel to balance itself. Now a pretty much off the shelf stock humanoid does the trick without special aids. It won't be long before these little hobby "toys" will be surpass the current capabilities of best lab robots. Several underlying technology trends are making them more and more capable. Rapidly advancing sensors of all sorts ( accelerometers, gyros, tactile, position feedback ) and massive distributed computing power provided by cheap chips like Cortex-M0 are closing a lot of loops, and even actuators such as shaped memory alloy linear motors are making new strides.

  5. Prior art on Using Fuel Depots Instead of Giant Rockets · · Score: 4, Informative

    This does not come up in a lot of these conversations, but we have a "fuel depot" in orbit right now. It uses storable propellants, not cryogenic ones, but nobody says you cannot leave LEO with nitrogen tetroxide and unsymmetrical dimethylhydrazine (UDMH). In fact, that propellant combination was exactly the one being used to land on the moon in Apollo program.

    The fuel depot on orbit of course is ISS Zarya or better known as FGB. It gets fuelled up by Proton's on a regular basis, and ISS uses the propellant for station keeping. Considering the mass of ISS, boosting its orbit is no small feat.

    Russians also have a spare module, used to be called FGB-2 sitting somewhere in the hangar. It was proposed as various additions to ISS at some point.

    In summary, storable hypergolic orbital propellant transfer is a well known, well developed and currently used technology. Yes you need quite a bit more of it to do burns with delta-v in order of km/s, but the maturity of the solution and abundance of off the shelf engines and propulsion module designs using hypergols may well outweigh cryogenics in overall system designs.
    Propellant is also relatively cheap, even nasty stuff like hydrazine, and just lifting more of it would provide the much needed demand side for the globally stagnant launch industry, which has been in the oversupply mode for years, i.e. there are far more operational rockets than there are paid payloads.

    The point that "propellant depots" is nothing new, and in fact NASA's current flagship HSF program uses it needs to be made more often. Switching to cryogenics would be a new development even if not that complicated, and may or may not be worth it, depending on overall mission requirements and other elements of system architecture.

  6. Re:Let me know when it passes the Turing Test on Meet Siri's Little Brother, Trapit · · Score: 1

    A lot of western researchers seem to think "true" AI is somehow the holy grail. Its the evolution and further combination of what you call the "expert systems", that is bringing about the presence of artificial intelligence in everyday lives. Even if this presence may not appear truly "intelligent", it will and is already surpassing humans in certain capabilities.

    You see, nothing says that the so called "expert systems" have to be based on canned logic and simple rules only, its perfectly possible to complement these by adaptive and evolving algorithms.

    Again, Turing test is a worthless and irrelevant measure, to anyone but ivory tower research types. Oh, and "popular science" media.

  7. Re:Let me know when it passes the Turing Test on Meet Siri's Little Brother, Trapit · · Score: 1

    Why ? Turing test is hardly a measure of useful artificial intelligence. Without getting into much details, even your friend wikipedia elaborates on the subject. The most important point is its irrelevance to real world applications. A car that drives you cross country autonomously does have a ton of useful AI in it, but for it to pass a Turing test would be just completely pointless. Neither would your home assistant robot that runs errands, does grocery shopping and household chores need to be able to chat with you from behind a curtain .. duh.

    How is any Apollo moonwalker really a hero anyway ? I mean, they were propelled to our nearest neighbor in a cold war "our germans are better than yours" pissing contest, orchestrated by a central design bureau, with the tax money of millions.

    Yes these were all brave and bright guys, hand picked "right stuff" material, but what extraordinary did they personally accomplish to become a "hero" ? I can understand how a propaganda machine back then, just as it did with Yang Liwei in 2003, went out of its way to proclaim them all heroes, but were they, really ?

    If you ask me, Burt Rutan or Elon Musk are much more of heroes of spaceflight thanks to their personal contributions on dragging the entire field out of state socialism mindset, than the twelve moonwalkers ever were.
