Yahoo Pipes
Yahoo Pipes allows you to manipulate rss
feeds. I built my first very simple pipe this morning. It takes the Amazon
Gold Box feed and strips out the Baby
Deals. You can also much fancier stuff like match geocoded addresses in
feed items and modify the content of individual items. Too bad they don't
provide a way to screen-scrape pages to build feeds.
If I build any more pipes, you'll be able to find them on my pipes page.
Power Magnet Update
In response to my questions about using Lua and
Lighttpd to serve up static blosxom pages, Tomas Carnecky sent me an email
with a better way to check for an empty query string within Lua, using "if
next(get) then return 1 end". Here's my new power-magnet.cml
-- if query string is empty and static file exists, serve static file
dr = request["DOCUMENT_ROOT"]
-- local f=assert(io.open(dr.."/debug.out","a"))
if next(get) then return 1 end
sn = request["SCRIPT_NAME"]
static = string.gsub(sn, '^/blog/(.*)$', '/static/%1')
if (file_isdir(dr .. static) and file_isreg(dr .. static .. "/index.html")) then
-- f:write("cache hit on directory\n")
output_include = { dr .. static .. "/index.html" }
return 0
elseif file_isreg(dr .. static) then
-- f:write("cache hit on file\n")
output_include = { dr .. static }
return 0
end
-- f:write("no cache hit\n")
return 1

JSTOR Proxy Greasemonkey Script
I've written my first greasemonkey script, to rewrite links to JSTOR. JSTOR contains articles from tons of journals, but you need to have a subscription to access it. My university has a license, but in order to use the site remotely, you must go through the school's proxy server. So my script appends the name of your proxy server onto the jstor.org domain, in my case libaccess.sjlibrary.org.
Update: It now supports ieeexplore.ieee.org url's too. I knew the name would come back to bite me. I guess I'll wait to rename it until I rewrite to handle multiple domains more cleanly.
Another Update: Support for
