  • Thank you for the interesting topic. I’ve learned and forgotten much of this over the years. In particular I enjoyed the comments about the generalization of the method that @Blaise Pascal posted.

    Something that caught my eye however was the third paragraph about the utility of integer math on small embedded controllers; this is probably worth an enginursday blog. I wanted to only use floating point when I started out programming PICs but was enlightened by my mentor of how to use integer math instead. After a while it became second nature. When I began to use compilers instead of assembly language, I still applied integer math and still do even though the compiler provided floating point libraries and my simple programs on large PIC32 chips had room and speed for floating point. Nothing religious here, it’s just a way of seeing and solving problems. Horses for courses.

  • It doesn’t always work out like you might think…


  • Well, the story has gone viral. It’s been on 4 or 5 clearing-house websites. I went back to Amazon to see if the reviews have change any — they have; the page has been taken down. Going to the publisher site, there is an apology and a statement that they are going to re-write the book.

  • Thanks for shining the broad light of day (and reason) on this trash. I’ve been cringing at the ‘Barbie’ aspect of American culture basically forever. I never understood why my wife bought them for our two daughters. Fortunately they grew up fine with no foolish ideas about gender - good for them! So exposure to Barbie is not the death knell as I thought it would be.

    One good sign: click on the Amazon link for that book and see that out of 115 reviews, 103 of them are 1 star - the lowest possible.

  • Wow! What a great list of resources! The ‘falling-fruit’ resonated with me. My wife’s depression-era father knew every fruit tree in a five mile radius of his home and would visit them at harvest time - sometimes late at night as the owners were not all into the ‘open source’ thing… ;>

  • Here’s my idea of a great workbench:


  • Excellent writeup! Thank you for taking the time to thoroughly explain your great project.

  • This is the best succinct description of the state of uav affairs I’ve yet seen. Thanks!

  • Yeah, but look how rewarding the learning experience has been - and will continue to be for the foreseeable future!

    All kidding aside, you took the right path. Keep having fun!

    Edit: it looks like the store in the photo right behind the truck has a good supply of ‘fix-it’ ointment.

  • Uh, I need to cancel an order for a red board; maybe after a month, I’ll re-enter it. Just don’t want to get one of the ones from the end of the show that fell on the floor.

    For those of you are humor (or humour) deprived, yeah, that was a joke. I have no order for a red board and further more, I am totally sure no red boards were harmed making that video. No, none at all. For future videos, I suggest that the hosts quaff a beer every 10 minutes of the video - might make things more entertaining.

No public wish lists :(
