Goodbye, Tuvalu
Tuvalu, the
Pacific island nation
and home of the fresh, new, exciting Web address .tv,
is closing
down. Being a flat island nation is bad when the sea
level is rising. [Metafilter]
I’m writing my O’Reilly talk into an article, and I’m fanatic about my
images looking good. See how nicely centered and anti-aliased that
little picture is? I use xfig to do
vector graphics, fig2dev to convert to PNM, then netpbm to scale the images
nicely. But netpbm was missing a tool to say “make the image this size
by padding it on all sides” (pnmpad isn’t that smart). So as a
procastrination tool, I wrote up the ugly shell script pnmpadtosize. Unix at
its best!
Way back when, the Internet was only 30 hosts wide. That is, the time-to-live field on packets in the common TCP/IP implementation was set to 30. If two hosts had more than 30 hops on their route, they couldn’t talk to each other. The Internet grew bigger than a diameter of 30 sometime in 1992 or so, and all those TCP/IP stacks had to be updated. I think most stacks now set the TTL to 255, the maximum.
Update: The Slashdot thread is surprisingly useful. It includes a link to the author’s slideware, but still no paper to be found.
