    I used to go on motorcycle rides and would go to the one closer to Shilshole/Golden Gates. One of the places I miss since moving to the East Coast the year this article was written…

    Feeling vindicated in having gotten rid of my windows comps and gmail. I used to have a dedicated linux box but lately have been preferring the ease of macs. Maybe one day I'll get…

    Probably depends greatly on the expanded configuration and what equipment is inside.

    The AC75 class is now going very fast as well with foils, over 50kts. Just recently the 40kt barrier was broken by hydrofoil windsurfers. Fins still have a higher top end but the g…

    Krita has gotten really great over the years, and it started out pretty good to begin with

    The upper stage re entering was the craziest thing I've seen live. Can't believe it was burning thru the flap and still had a gentle splash down.

    In my brief stint working on spacecraft in the private sector I worked with guys like you that did beautiful things with wiring that I loved to see. I hear you on scheduling too. I…

    Nowhere near as extreme but I broke my leg and there was a weird sensation if I touched my leg near the break, my toes would tingle even though they were quite a ways away. Years l…

    Nuclear has a large heat source (or can make a large heat source instead of converting to electric first) to do a lot of things like this.

    I was hoping there would be something here about using Stirling engines that use decay heat, but looks like they are just using the decay heat itself and not generating electricity…

    It really seems like the ancients knew quite a bit. Their system for counting and for angles seems to have been really handy. And the measurement system of feet and inches was real…

    How heavy are you going? It definitely isn't boring to do heavy squats.

    A good counterpoint to show someone who did stay fit is Jack LaLanne.

    I remember falling off of a tall monkey bar thing like that and getting the wind knocked out of me the first time. And a lot of other equipment that I haven't seen in decades.

    It would be interesting to see a cross section and what kind of variable geometry they are using to max out in the different flight regimes. I poked around and didn't see that, and…

    IIRC that is due to other issues, not aerodynamics. For instance, the engine no longer receiving oil at negative 1 g, or fuel, as the system is designed for gravity flow. Stunt pla…

    Same, but different industry. Lots of re-engineering of the wheel after the original designers give their warnings and recommendations, but everyone's too smart to try the simple t…

    It also changes a lot for sailboats, and even more for faster sailing craft (windsurfers, etc.). You can feel a much stronger pressure in the sail when moving towards the wind on a…
