    It wasn't attached to the bottom of the rocket, though, which is bolted to concrete. I'm not sure it was even standing, it might have been already on its side for installation of the tank bulkheads, which had been seen there recently. That would have been a really weak position to be in the wind.

    So far, SpaceX are the only folks we can trust to even have manned flights. Orion is an albatross about NASA's neck and needs to be cancelled ASAP. NASA should no longer make its own rockets. Takes 10 times as long and 100 times as expensive, and they killed their share of astronauts with really stupid stuff. Every time was "go fever" and acceptance of known problems with the craft that should have stopped flight. Did you know the tank stirrer that blew up the SM in Apollo 13 was already scheduled to be removed from future vehicles? Boeing may get their stuff together eventually with CST-100. Blue Origin is still suborbital-only for years. Sierra Nevada is going really slowly. I don't think you can judge SpaceX's preparation for mann

    Launch viewing is a frustrating hobby. I drove 5 hours to Vandenberg for the last launch, it scrubbed in the last seconds of the countdown due to a hydrogen leak. Drove 5 hours back home. For one SpaceX launch there, it was so foggy that I only heard it. Expect to see one for every three that you go to.

    It looks like the first Crew Dragon demo is on the 9th, during Orlando Hamcation, so I'll be in Florida. Hope that works out. I saw the Falcon Heavy launch that way last year.

    I went inside of the Rotron one day in Mojave about 10 years ago. It was standing on display next to a video kiosk, and they put the PC controlling the kiosk in the rotron, and that day the PC guy had left the door on the bottom of the Rotron unlocked. Of course some things could have been removed from the Rotron by then, but the inside was hollow. A few small tanks, and the control cab way up where I couldn't reach it. Birds were nesting in it.

    I am a big fan of Elon Musk, Tesla, and SpaceX. That said, this is the most half-assed project I've seen them do, and that includes the Monty-Python-esque brick tower constructed for Boring company for which they advertised a position for someone to be at the top and yell abuse in an outrageous french accent. I assume this person was in the Tesla lay-offs.

    Its construction was like that of a film set, and like a film set it got blown over in the first high wind. Inside there is a triangular truss structure like that on one of those overhead signs that spans a wide highway. This is the only structural component. Hung off of that is crinkly thin stainless steel skin attached to a structure made out of rebar. I kid you not. So, the skin has the approximate wind profile that it should (oops!) and most importantly, it looks cool!

    Well, not as cool as a real space rocket.

    Now, I know the job of this other than looking cool is to allow them to test the landing guidance software with the approximately right sized object, and these things tend to blow up and crash so it's OK to make it to be disposable. But they have now learned that you need a hurricane-proof building if you are going to do this on the extreme south coast of Texas right on the water! Or at least guy wires.

    I'm sure they'll have another one in less than two months. It'll be interesting seeing it "hop".

    The replacement for Hangouts SMS/MMS on the desktop browser is Messages for Web, at messages.android.com . You use this by installing the Messages app on your Android device, and then choosing Messages for Web in the app menu and scanning the QR code presented by the desktop browser.

    It sounds to me like this requires that you leave your phone on with Messages running in background, as SMS and MMS are sent through your phone in response to a network connection. Project Fi and Hangouts can currently handle SMS directly from your desktop.

    No, there is no such thing as a GPS transponder. GPS can only be received, unless you are the satellite. Now, you think it's a GPS transponder, but it's something else.

  16. Not a GPS transponder on New Satellite Network Will Make It Impossible For a Commercial Airplane To Vanish (cbsnews.com) · · Score: 3, Informative

    GPS is a receiver (unless you're the satellite). It's probably ADS-B they're talking about. This takes the GPS position as input, and transmits position information which can appear on air traffic control screens superimposed with radar.

    It's possible to lie about your GPS position. This is why air traffic controllers have not stopped using radar (they know something is there whether it's squawking the right information from its ADS-B transponder or not).

    It is also possible to screw up your local air traffic controller with spoofed ADS-B transmissions. Cryptographic signature is not part of the system yet.

    You can get raw heirloom almonds from some health food stores.

    Although you can grow them from seed, this is not how almonds are grown by farmers. Almost every fruit tree is a graft of the fruit bearing plant onto a different variety that provides hardy root stock. So, you can have almonds with the desired characteristics, and the very best roots feeding them. So, almond plants are normally from a cutting which is grafted onto a root plant which was grown from seed or from a cutting.

    OSI was founded to evangelize the idea of Free Software with different language, because at the time RMS wasn't really reaching business people - the message of a priori valuation of freedom over all else still plays best with programmers. Today many have reached an appreciation of Free Software starting with Open Source's gentler introduction. I don't deny that one person actively deprecated RMS. But it's long over.

    No, this one isn't a red hat issue. This is an issue that people created "Open Source companies", and then got upset because some really big rich companies ;like Amazon and Google actually used their software under the rules of Open Source, and made all of the money offering the software as a service while the actual authors of the software didn't do too well financially.

    So, maybe the business methods of "Open Source companies" don't actually work for some of these companies. Others are doing quite well, of course. That some companies have a business method problem doesn't make me nervous, because the companies only produce a small fraction of all of the Open Source that is being made. I'll help them if I can, but I won't sacrifice the values behind Open Source in doing so.

  25. Most Open Source is still made today by people who don't care if they make money or not. They are making it in a cost center to do something necessary for their business, not to sell it, or sell services for it.

    If all of those "Open Source companies" were to die tomorrow, it would not significantly diminish the amount of Open Source being produced.

    Don't confuse the needs of the companies with the good of Open Source.
