Palm m500, Spybotics, and Linux
Posted by Keilaron on Thursday, August 30. 2007 in Hardware, Linux
So I've gotten a new Palm.
My reasoning for this purchase was that I could use it to write while on the go, or even just if I felt like writing somewhere other than at home. Naturally, I got a keyboard for it as well as I wasn't going to be able to write all that much using the stylus (it has character recognition (at least technically), but I don't enjoy handwriting). Sadly, I neglected to notice that it didn't include a sync cable/cradle in the bundle, and had to get that separately. While waiting for it to arrive, though, I've been fairly impatient about getting programs on there.
Especially the driver for the keyboard!
Thus, I decided to try the only two other methods available to get data onto the Palm: infrared and SD card. I don't have a card reader/writer, so I thought that option was out (turns out it isn't quite - more on that later), so I proceeded with trying to communicate using the infrared port. You see, I eventually remembered that the Lego Spybotics kits that I have came with infrared transceivers; I figured they'd be good enough to transmit data to the Palm.
I first thought of trying it with my Windows system, but the transceivers connect on the serial port and I didn't bother putting a panel for one (the onboard ports of this motherboard don't actually include a serial port), and didn't feel like going through the hassle of adding it (not that it's that much effort, mind you). Instead, I used my laptop, which currently has Zenwalk Linux installed on it. Getting the infrared support was fairly simple (new kernel config plus the tool package), and one reboot later I was in business.
Sort of, anyway.
Linux seems to receive the data from the Palm just fine, and it seems to respond in kind; However, the Palm makes no sign of receiving anything, and eventually gives up on the connection attempt. It seems the problem stems from the most unlikely-seeming source: The Spybotics infrared transceiver. It's not meant for this sort of thing, really; When you use it to transmit data to a spybot, it's actually plugged in directly. I think you can use it to "broadcast" infrared signals to it too, but I don't really remember how that works and if it actually transmits any information. Therefore, I believe it's only meant for really short distances, and the problem with that is that the transmitter and receiver on the Palm aren't spaced the same as the ones on the Spybotics transceiver, and thus one doesn't see the other in one way or another.
I might try putting a much larger distance between the two and see if that works better... infrared is supposed to be able to do more than an inch or two, after all, but unless I had a very specific distance between the transceiver and the Palm, nothing showed up on either side... it's weird.
More on Celty

Alternative title: Oh boy, we're going to have our hands full!
I'm not sure it's hit my mother yet how much effort it's going to take to train this kitten - because we're going to have to, I'm sure - especially as she seems to be a bit of the stubborn kind. Or maybe she's just that energetic, which makes more sense as she's still a kitten.
The movies are up now, but may require IE, sadly. Movies are XviD encoded to make sure to grab (or update) your CCCP.
I forgot to mention last time: We had a choice of a black male named Riker, a peach/tan-colored male (I don't really remember his color, and at the time I had trouble deciding what to call that color to call it), Celty (pronounced Kelty, by the way), and a gray faintly-striped female who apparently, despite not being the eldest managed, to be the alpha of the family. Originally, we were to get Riker (this was, I think, my mother's choice), but after looking up information on introducing a new cat (and asking our vet) we found that it was better to introduce a cat of opposite gender and thus upon hearing that we had the pick of the litter I immediately ruled out males as an option. Possibly unfortunate, as Riker did look cute, and the tan-colored male seemed to be the submissive type (though playful). I wanted a somewhat creatively colored kitten, so that pretty much left me with just the choice of Celty.
But... she's a noisy one when not being given attention... and those claws!
We've got a new kitten! :o

That's right... There's a new kitten in town, or rather in the house, and her name's Celty.
I didn't think it was entirely a good idea, as Gizmo doesn't seem to react well to visitors... but I figured he could use some company. So far, however, they're not really getting along. Of course, this is no real surprise as Gizmo's never had any visitors save the mutt, which my mother gave him grief for (And does he ever remember!). Sadly, this means it's nearly impossible to even pet him right now as he's so ticked off and afraid that he doesn't want to be near us. I'm actually afraid he might run away.
The kitten, however, seems to be adjusting to her new home alright, although whenever she's awake she's clamoring for attention. Toys aren't good enough for her because she wants some actual interaction with another being - not surprising as she was just separated from her family. Thankfully, she's already litter-trained, and despite being locked up in my sister's room for a night or so, doesn't seem to be scratching anything (at least nothing that's already been, or is not carpet). I think she hasn't yet reached teething stage, though...
Either way, pictures of the new kitten. Videos as soon as ffmpeg is installed, but they're not great - I already had to boost the brightness and contrast.
The Blue Marble
Posted by Keilaron on Sunday, August 5. 2007 in News & Events
This spectacular "blue marble" image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.
NASA has posted on their website some beautiful high-resolution (2048x2048, also 540x540 for the squeamish) pictures of the Earth, entitled "The Blue Marble". What nice desktop images they make... at least, if you like the space view of the Earth. I may share some optimised pictures (GIMP autocrops the image to 1840x1840, meaning there's a good 54-pixel black border on each side - and I mean pure or near-pure black, not including the fading blue around the Earth.) and some resizes if anyone is interested.
