What did you discover today?

FCN 5 belt driven fixie for city bits
CAADX 105 beastie for bumpy bits

    Coffe slops out of a cup easily when you are walking because the natural frequency of oscillation of coffee in an averagely sized cup just happens to be about the same as the frequency of walking. Something rather beautiful about that.

    Oh so that's what those things that look like blackberries but aren't and don't taste the same are. Thanks, now I know what to call them.

    So that's what I learned.
    I used to just ride my bike to work but now I find myself going out looking for bigger and bigger hills.

    Ha - very strange. I have just spent 20 minutes reading up on the theory after seeing something on LFGSS.

    Oh - and I learned that 39x25 is not enough for a long hill of 8% when you weigh as much as I do.

    I don't remember seeing them whe I lived oop North, but there seem to be loads of them on the edges of the fenland.
    Cloudberries seem more like a North Scottish thing.

    I learnt that when you are stressed and worried about money and your job, you shouldn't shout at your wife for buying small items in readiness for xmas - even if she does appear to be buying too many!

    it does NOT constructively help in any way what so ever!

    Most of them do if you can find one with an actual in-store bakery as opposed to a place where they've stuck a couple of ovens and just tip in frozen semi-baked loaves every so often. My local Sainsburys used to give you 50g for nothing if you asked nicely. Then I moved and then I discovered the joys of sourdough...

    I learned that Plumstead isn't where I thought it was. It's closer by about 5 miles and a river...

    That if my job title has "software" in it, I need to be extremely careful to let absolutely everyone involved know what is happening before I start messing with the Verilog. Even when the people who are messing with the Verilog as their job ask me for advice. Meh. All the tests still pass. Just a few ruffled feathers.

    I learned that DDD's sex life is on the wane due to him getting older. :wink:
    None of the above should be taken seriously, and certainly not personally.

    Proteins may have Quaternary structure. Thanks to 16YO for that.


    Konrad Zuse had a pretty neat design for a full adder:
    http://tams-www.informatik.uni-hamburg. ... seadd.html
    http://asr.menloschool.org/2ndSemester/ ... Daniel.pdf
    Note that the carry-signal is propagated instantly after the input values A and B and the (dual-rail encoded) Carry input are applied to the circuit. Therefore, an n-bit adder is almost as fast as a 1-bit adder, because the propagation of the electrical signals is much faster than the switching time of the relays.
    If you're interested in the history of computation, and you haven't heard of Zuse, you should check him out. He figured out most of the important stuff in IEEE754 in about 1938. Unfortunately, CPUs are usually designed by numerical numpties, so the lessons are often not learned.

    That I melt on a turbo (and that if I'm organised and pull my finger out I may be able to get home, get in kit and chase you lot down to do a 20m loop before 7.30pm)...
    What do you mean you think 64cm is a big frame?

    That a Guibo (pronounced gwee-bo) is actually a vernacular spelling and is in fact a Giubo (pronounced in italian as joo-bo).

    That if you wear old baggy trackies over the top of your rights while you're getting ready in the morning, and forget you're still wearing them for the first five miles, you feel quite toasty but very silly.

    I think that dorsum refers to your back, or the back of any part of the body. Would say " the dorsum of my hand" rather than just "dorsum". Latin, innit.
