  1. Aquaculture and hydroponics on Space Fish: ISS Aquatic Habitat Delivered By HTV-3 · · Score: 4, Interesting

    Aquatic critters can be one link in a combined waste treatment / hydro-ponic growing system. I've heard that a cubic meter of sea water is the most prolific growing medium on earth. I'm interested in the downstream outcomes of science like this.

    Also am reminded of an old pulp sc-fi short story that took the form of letters between a Mars bio-dome colonist and the manufacturer of the living bio dome system... they kept adding critters to the dome to try and balance the eco-system, with predictable and silly results.

  2. ROV mining etc on Details of Chinese Moon Rocket Emerge · · Score: 2

    I doubt human lift is the goal. This is a way to get more robots up. Once I had seen a video of telepresence underground heavy mining equipment i had an idea how its going to play out. Semi-autonomous robotic industry.

    Given the thermal gradients, I wouldn't be surprised by a closed cycle heat engine driving them.. i'm sure it works out better than solar panels.

  3. Re:Electric Universe pulsars, etc on Weak Solar Convection 100 Times Slower Than Predicted · · Score: 1

    I too remain open and skeptical of BOTH the unproven established theories and the unproven alternatives. One thing that really made me consider the electric theories is pulsar rotations. I find it much easier to conceive of a fast rotating electric field causing the periodicity than super fast spinning hyper dense matter.

  4. Similar to electricity distribution AC vs DC on AOL: Outdoor Server Huts Are the Future · · Score: 1

    This is reminiscent of the original standards battle between AC vs DC distribution systems.. monolithic centralized infrastructure vs distributed regional systems. You remember the one where Edison electrocuted an elephant.

    Anyways the pendulum goes back and forth on these things, and if period doubling is occurring that means that fine grained rapid deployment is required to keep pace with that. Won't be long before data centres are riding electric trains, semi-trucks (a la Walmart's warehouse on wheels model) or even public transit busses with high speed datalinks to physically shorten that last mile.

    Why is Google so interested in autonomous vehicles anyways? Could it be something do with an inevitable trajectory towards automated containerized data centre deployment? After all, there is a similarity with a third world concept where poverty drives innovation. So really shouldn't the discussion be about graphing costs of data delivery vs cost of caching & updating?

  5. Even if you win the rat race, you're still a rat on Young Listeners Opt For Streaming Over Owning · · Score: 4, Insightful

    Bandwidth and power used by internet infrastructure is a waste of money and energy compared to playing locally off a low power digital device. Streaming only serves to commodify usage similar to how industries have eked their way into every "payable" crevasse of our existence. Its vampiric how our little time here has been turned into being wage slaves for ideas such as this. Even if you win the rat race, you're still a rat.

  8. Two fire extinguishers, one to put out the fire... on Grilling For Geeks · · Score: 1

    Having had a near disaster barbecue propane incident occur at a friends house, I highly suggest at least one fire extinguisher. Nothing boosts geek cred like swearing at fire department telephone dispatch while calmly knocking down a 12 foot pillar of roaring flame from an openly venting propane tank.

    Discharge the extinguisher at the base of the flames, and using a glove, turn off the tank valve.. it will be freezing cold and the tank will be covered in ice. First aid for flash burns is to immerse in cool water, no ice. And actually I suggest 2 extinguishers.. One to put out the fire and one to put out the fires started by the fire.

    A dry road with a little oil on it drives fine.. then when it rains, very slippery. It is not the oil, its the combination of it with water thats the problem.

  11. How durable? on MIT Creates Superhydrophobic Condiment Bottles · · Score: 4, Interesting

    Is it durable enough to be used on washless or "rinse-off" dishes? Also possible application as a coating on bathroom fixtures, or perhaps applied to the inside of wax paper bags so the icing stays on my take-out snax.. come to think of it toothpaste tubes and racing swimsuits. Let alone the prank potential!

    This stuff should probably be shipped in double walled tanker trucks.. hate to see what it does when spilt on a roadway.

  13. Displacement caused by shoreline erosion on Human Water Use Accounts For 42% of Recent Sea Level Rise · · Score: 1

    umm... any beachgoer knows that the sea tosses up sand, rocks and debris during storm season, and also breaks the big rocks into little ones, pulling the shoreline under the water. Since coastlines are fractal, they can be very long for a certain somewhat small area of water.. also fresh sediments washed downstream from all the river systems. What about the displacements caused by these effects on the seabed, or sea plants and animals fixing atmospheric gasses into their biomass? No doubt these things have been considered.. but have they been considered accurately?

  14. facial recognition search on Toronto Police Use Facebook Picture in Online Lineup · · Score: 1, Interesting

    If facial recognition on a dataset is used to find potential matches this seemingly would increase the chances of a false identification being made. After all, some people do look alike, and the more similar they are, the more likely a human witness would get it wrong when presented with those artificially limited choices.

  17. Fix computers and network that way for local jobs on Ask Slashdot: Money-Making Home-Based Tech Skills? · · Score: 3, Interesting

    Everyone knows someone with computer trouble and often its not that hard to resolve. Especially if you can do it as a house-call.

    Additionally, people with computers are often trying to do things with them.. websites, imagery, newsletters, blogs, etc. and many folks don't know how.

    Setting them up document templates, blogs, and other workflow in addition to good free software, and advising on purchases is a good way to go for someone with even modest experience.

    Computer experience is a "culture" of knowledge that many people aren't connected to. By having face-time with your clients you can know them well enough to do remote desktop or phone support from home on their projects as they do them. They will recommend you to everyone they know if they are happy and that can lead to bigger contracts. In home-based you need both the big and the small contracts.

    This can also lead to doing contra with any local businesses you are a customer of. woohoo!

  20. Re:Magnetic field + conductor = Electricity? on 'Electric Earth' Could Explain Planet's Rotation · · Score: 1

    It might have been the difference in potential between ground points.

    My brother was doing some sort of Geo survey work where they ground a wire in a creek and then run it quite a distance to another location for sensing purposes. He told of big static discharges that could really set you down on your ass by contacting the wire once it was at the other location.

  21. lol - trolling the fineprint on Ask Slashdot: Tools For Teaching High School Kids How To Make Games? · · Score: 1

    LOL this entire submission is better suited for April 1.. Read the fineprint in it, and then check all the threads. No body has read it all or fulfills it all. Each of the threads ignores the part of the submission that excludes their suggestion re: specific platform support, specific tools, etc. Its doubtful there is actually an answer.

    A workshop that meets weekly and they "actually create a game, start to finish" without programming, but programmers can work on it.. Platform specific, but excluding most dev tools for those platforms.. without skills but has to be a skillful task. Perhaps the only solution satisfying all that is a checkers game using everyones smartphones as the gamepieces.

  22. Re: Unity version control on Ask Slashdot: Tools For Teaching High School Kids How To Make Games? · · Score: 1

    Since packages can include all those components and relationships. If you make a "hierarchy" of packages that you import and Unity project folders that contain things that you sellect & export packages from in their entirety, that can work around most of that suffering. (ie click on your scene, select dependencies, uncheck common things you don't want in the package and export)

  23. Javascript - for both Unity3D and HTML5/Webkit/CSS on Ask Slashdot: Tools For Teaching High School Kids How To Make Games? · · Score: 1

    Javascript is what you should teach them. Not the high fallutin everything about it, just the code ganking basics. That way they can use both Unity(free) and make simple and neat HTML5 / Webkit CSS stuff (free). Get their feet wet fast & give them real life skills and a subject they can geek out on in their own time.

    Teach them a little bit about "objects" and then using .CSS and an HTML5 / Webkit browser with extensive documentation.. such as Safari *ahem*. It really can do some amazing things without a lot of overhead. If you've missed developments there, then go look. This will also let them make cool web projects that aren't so interactive for the lower achievers.

    Build something simple using a browser. Lots of gui events and behaviours are handled by the .CSS objects. Strap it together with a bit of Javascript. Check online.. lots of little demos for you to find and use for your curriculum. The result will work cross platform depending on the various implementations of webkit.

    Then for the real deal, Unity. Its great. Altho you'll need more of a structured programming plan and an understanding of how unity is auto-magically "helping" you and where you need to take over and make your own event handlers.

    Unity supports both Javascript and C#. To get around project-build / version control problems: export all your modules as a package and submit that into your version control. Then to get the newest version into your project, update your packages & then just re-import that package into your project.

  24. Undamaged Replica? on Iranian TV Shows Downed US Drone · · Score: 5, Interesting

    Despite extensive covering on the underside, to me it looks TOO fresh and undamaged. It doesn't look used at all

    I think this is a mold reproduction of whatever they did get, faired out the damaged areas, swapped over a few parts and the paint is is still wet. There is nothing underneath it, its just a surface shell that looks right.
