Studies on a hashtag

I'm at the EGEE09 conference this week, and they're also plugging use of tagging in social networking such as the #egee hashtag in twitter and the 'egee09' tag in flickr. As a small experiment I created an IRC channel on freenode (#EGEE09) and announced it with a hashtag on twitter. Within 3 minutes there were an additional 3 users, only one of whom was in my normal twitter cloud, ie the other 2 came in purely from the hashtag (and one of those was under a minute later)

so, twitter is certainly becoming a respectable way of broadcasting announcements to an interested group of people who are subscribing to a hashtag.

oh and as an aside, the IRC channel paid off -- I discovered that GridPP had some nice laptop bags via it and secured one for myself during coffee.

Anyway, back to more important work -- listening to how the EU proposes to carve up the funding for call7

BeautifulSoup + savannah

At work, we use savanne to power where we keep track of all the glite-middleware (amongst other things)

However, one of the problems with savanne/savannah is that it doesn't have a nice machine readable API, but requires the user to click with a browser.

Cue Beautiful Soup and lo, the python SavannahCLI was born.

Well, in its early years it was unloved and handed round from developer to developer, until it arrived as a pedantic teenager to yours truly who decided to get rid of the horrible 'operation, item, name, value" syntax and replace with something more, um, fluid instead. (--patch 1234 --set foo=bar). It also had a huge set of hard coded lookup tables for converting select items to names and vice versa -- WHY?

thanks to some googling, I came across this which, with a little refinement gave me:

def enum_forms():
# we search within the table tag so that we lose the LHS searchbox
selects = soup.find('table').findAll('select')
for sel in selects:
sel_name = sel['name']
print "SELECT NAME=%s" % sel_name
for o in sel.findAll('option'):
print " %s, %s" % (o['value'],o.renderContents())

hey, it's not finished yet, but sure saves a whole pile of hard-coded badness.

Feeling Pumped!

Having just had a day without power, and then going round the site to check everything came back online correctly (including services such a...
