  1. Re:No they didn't Rei and Bruce on Tesla Short-Sellers Lose $1 Billion (cnbc.com) · · Score: 1

    "Shorties" may have a use but I can only see bad coming from it as they dig up the dirt (the spot on the clean page) to look full page. We see this all the time with graphs cropped to give the negative view that suits. At the end of the day the shorties are in the business of making money and will do (as we all see) anything to turn that profit. I would go so far as to say that shorts are anti-capitalist; working to damage a potentially profitable company.

    If you need "Stock market police" then get the government to do it rather than a business as the business is in the business of profit.

    It's like privatised prisons being pushed here in NZ; it profit them not to reduce the number of residents rather grow the population. More prisons = more profit. Rehabilitation? Silly idea from a profit perspective. Long term incarceration? Great! Inmates train other inmates on tricks to do when they get out increases the odds of returning customers.

  2. Tesla possibly hoarding cars until July... on Cost To Build a Tesla Model 3 Is $28,000, German Engineers Say (www.wiwo.de) · · Score: 3, Insightful

    This could be the reason why "Tesla is still in the process of moving from 3,500 to 5,000-6,000 per week by the end of this quarter".

    Basically they might be stockpiling cars until after the next quarter starts (July) so that the maximum number of buyers can take advantage of the full tax credit.

    Not a fan of the death penalty but if you're going to check-out, be it by choice or inflicted then this is one of the nicest ways to go (& cheap/simple). Light headed & pass out. Helium balloons work too but you need a mask to keep the thing in place.

    What's good for CO2 scrubbing? A simple balloon rebreather & CO2 absorber should do the job if a bit slower while the O2 converts. I guess I'm coming at this problem from the euthanasia angle rather than the "kill our citizens" one... Not speaking from experience realise... ;) [well I think we've all gone light-headed with the Helium thing]

  9. Re:Gravity at 100km is only 3% less that sea level on Blue Origin Launches Its First Test Flight of 2018 (mashable.com) · · Score: 1

    True, but no different than being in microgravity during orbit. This is also due to being in free-fall.

    [We could be talking about different things here... but I've typed it up so out it goes...]

    Not quite... During orbit you have the orbital velocity to create the centripetal force to constantly counter the fall (aka orbit). This rocket is just strait up & down. This certainly makes re-entry simple as you don't have to deal with the orbital deceleration energies (ablation / retros) but you'll never attain orbit or leave this planet for more than a few minutes with "this" setup. With this you do get to tick the 100km altitude attained checkbox which is what it's primarily about for now.

    That said, I do salute them and the setup will almost certainly evolve... Great times! :)

  10. Kármán Club? on Blue Origin Launches Its First Test Flight of 2018 (mashable.com) · · Score: 1

    The Mile High Club has a new goal; perhaps the Kármán Club? How long do you have weightlessness in the Blue Origin (aptly named colour)? I'd only need a minute or two...

  11. Gravity at 100km is only 3% less that sea level.. on Blue Origin Launches Its First Test Flight of 2018 (mashable.com) · · Score: 2

    From WikiPedia:

    Gravitational acceleration at the Kármán line, the boundary between Earth's atmosphere and outer space which lies at an altitude of 100 km, is only about 3% lower than at sea level.

    If I weigh 100kg (ok, 100lb, this is /.) then I would weigh 97 at 100km. The majority of the 'weightlessness' is just free-fall; sort of a massive erect vomit-comet. :)

  12. Still using my Note 2... on The Smartphone Sales Slowdown is Real (axios.com) · · Score: 1

    ---and as spares I bought 2 second hand for nix off TradeMe (eBay equiv in NZ). The newer models have higher res (but beyond my unassisted resolution), better cameras (my one is good enough), faster/more cores (no processing issues) and more RAM (well that's something that would help but not a show-stopper yet).

    There's just no good reason for me to change yet... And I won't be crying if I break it... just swap in more bits from the other carcasses. When I can't fix it any more... well then I'll upgrade then & celebrate the good run that I have had.

  14. Similar to ICFs (Insulating Concrete Forms) on 3D-Printed Public Housing Unveiled in France (reuters.com) · · Score: 1

    The basic construction is similar to ICFs (Insulating Concrete Forms) in that there are 2 outer layers of foam with ties (manually placed in this robot build) and rebar/reinforcing-bar in the cavity.

    While the robot arm does place the foam it looks like there is a lot of manual interventions... typically ties are placed 150mm (6") to 200mm (8") horizontally & 300mm (12") to 450mm (18") vertically. The ties are to resist the pressure of the concrete inside the foam walls from splitting the walls apart. Even so you only fill the walls 1m (3') and let the concrete set a bit (~20-30min) before doing the next lift (layer). Also you generally put horizontal rebar in every 450mm (18") to 600mm (2') though it's not uncommon to use little stainless steel toothpicks (eg Helix) mixed in the concrete to save the hassle esp in curved walls.

    Foam is a good insulator & concrete is solid/quiet/fire-resistant/storm-resistant. There's could be good thermal mass too but it's inaccessible because of the dual foam sandwich.

    Yes, I'm researching building a house out or ICFs... :) The blocks can be done by anyone though you need to understand all the pitfalls (of which there are many).

    Here's a rough outline of what ICFs are (low quality video but gives you the idea in a few minutes):

    We used to heat with fan heaters / gas heaters. The heatpump we installed made a huge difference. Much more output for less power consumed. Don't tend to use if in Summer (now, NZ); just open a couple of windows and the cross-ventilation is enough.

    I think most aircraft already broadcast their location via ADS-B:

    Flight info.

    I don't know a lot about it but I believe people track these things for fun (& it sounds like fun too!). I would expect that they pour this info into a global database too. It would make sense for Google to tap this info and use a planes location & expected location as part of its prediction.

    Actually, I think there's a scheme (possibly active) out to have LEO satellites tracking this info to mitigate the "lost aircraft" events that we had a cluster of not so long ago. It cost lots of $ trying to find planes full of people that disappear without a trace.

    I wonder if SpaceX / RocketLab etc. have transponders? I would expect so but what about those military launches? Probably turned off for those...
