    Why do I feel a little bit of evilness in CmdrTaco's 'ho-ho-ho'...

    Judging from the comments, it seems his christmas tree replies to pings quite fast too

    Is it just me or is Twitter the most annoying thing to take off in years?
    • No one said you had to use it. For my part? I think Twitter has a ton of possibilities.

        So just to clarify, the number of possibilities that Twitter has is approximately 1.0160469088 tonne, or 35.71 bushels (corn), or equivalent to the weight of 5555.5 wamprats, like a small car.

          twitter has 140^68 possibilities. 140 characters to the power of every possible character on a keyboard. and just like twitter 99% of those possibilities make no sense to sane intelligent people.

            greetings and salutations...
            My only real problems with twitter are these:
            a) I am not sure I can say anything of substance in 140 characters...
            b) Twitter promotes the idea that anyone else cares about what you are doing every 30 seconds of the day....Trust me...WE DO NOT CARE.

    • why couldn't he just use some UDP based server thing rather than this stupid HTTP-based commercial service that nobody wants to invest in?

    My tree isn't publicly-networked, but I'm pretty proud of it and love to show it off :-)

    Each light has its own microcontroller & RGB led. The lights are autonomous, but can be orchestrated by the controller.

  • a Symantec spokesman announced today that they had found vulnerabilities in the Christmas Tree Webserver. "It's terribly easy to DDOS the tree. I mean, it's using an 8-bit PIC MCU that can only service a dozen or so requests a second. We recommend protecting the Christmas Tree with NAV-XMAS version, or at the very least, putting the tree behind a firewall, as we can't guarantee that the tree won't go up in flames when the next malicious attacker strikes."
  • Oh, say, maybe spend some time with the family in front of your own tree? C'mon now, you can still sing Klingon Christmas carols!

    You can do this with an mbed and not need to etch your own PCB or solder SMT components. I got one when they first shipped and let me say they are a pleasure to work with. Ethernet, USB, serial (rs232, SPI, i2c), PWM, Analog in and out as well as digital in and out. Small compact foot print that is DIP compatible. The best pat is it is programed with c++ instead of assembly. You don't need a programmer either as you plug it into any PC (Works with Linux, OSX and Win) via usb and shows up as a 2mb flash disk and you drag and drop the binary to the disk and hit the reset button. The only down side is the compiler is online so its sorta cloud based but there are third party compilers for the ARM Cortex that will work with the mbed.

    No I am not paid to plug this device, its just been a while since I had this much fun playing with embedded hardware. http://www.mbed.org/ [mbed.org]

      Mbed - $66
      attiny - $1
      Sometimes you just need to control some lights. Yes, it is good for prototyping one light, but when you need 100 lights each with its own controller, simple parts are best.

    No, that still doesn't make Twitter good for anything.
