[link] (1) 2006-11-02T22:19:01 laptop stickers:

After reading http://jeffwinkler.net/2006/08/04/python-and-the-nod/ , I printed stickers of things I like and put them on my laptop. I deliberately chose the old-style python logo.

Bloglines gave me a hires version of their logo, but asked that I fax their legal department a permission/licensing form. In some other cases, I just used a low res image. This project is not about image quality.

The hardware is all attached with velcro. I can rip off the gps and stick it to my car's ceiling, for example, or stick the usb drive to a sweater. I wish I had a right-angle usb connector and a small, flat hub so I could connect the usb devices all the time.

Today I wrote a thing with the python gps module (from gpsd), a nevow website with livepage, and google maps. Then I went out on the road with a gps receiver, laptop, and Treo 600 and broadcasted my position. You could watch me move at http://maps.bigasterisk.com

darcs get http://darcs.bigasterisk.com/maps

to get the code, or just look at:

http://darcs.bigasterisk.com/maps/serve

http://darcs.bigasterisk.com/maps/postPosition

for the good parts.

http://www.newt.com/debian/treo650.html is the best page about doing bluetooth hotsync and DUN with a sprint treo 650. The main trap on hotsync is that if you disobey and put in a hostname along with the host ip address, various things will stop working. Use "tcpdump -i ppp0" after ppp connects to debug. Also, treo camera pictures don't backup with "pilot-xfer -b .". I'm not sure how to make those backup, but you probably put them on an SD card anyway.

The DUN section of that page is for t-mobile, and I use sprint. My /etc/chatscripts/sprint is like this:

TIMEOUT 3
ABORT ERROR
ABORT BUSY
ABORT VOICE
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "NO DIAL TONE"
ABORT "NO ANSWER"
"" "ATZ"
"" "AT&FH0L3"
OK-AT-OK "ATDP#777"
TIMEOUT 75
CONNECT

The first timeout is small because the first AT command always times out for me, and the connection seems to work fine. On ubuntu, my /etc/ppp/peers/sprint starts with "/dev/rfcomm1".

I use 'pon sprint' to start the dialing instead of ifup.

[link] 2006-11-29T11:36:30 RDF literals as subjects:

Any proposal about allowing RDF literals as subjects, especially one that's for language purposes (in this case it's direction support), needs to address why RDF's current design has the exceptional 'language' attribute on literals. If your proposal is so good, why didn't RDF allow arcs from literals in the first place and avoid the langage/datatype special cases altogether?

I really know nothing about the direction support issue, but if it's one of the last few language-specific issues and it really ought to be separate from the 'langauge' attribute, I am inclined to prefer one more special case on literals than a total redo of the constraints on rdf graphs. My main concern with literals as subjects is that people will treat them like "casual" URIs that aren't universally unique.
