Better living
through
feed aggregation
Web feeds
make my
life better
I no longer
have to visit
my favourite sites
individually
I just visit
Google Reader
and all my
favourite sites
are there
I can
consume data
at least
10 times
more efficiently
Which frees up
a lot more
of my time
To spend
with family
and friends
Or
(more likely)
Gives me time
to consume
10 times
as much data
Lots of
good information
in web feeds
Blogs
News
Every site
produces
web feeds
(Well every site
except
Facebook)
Reading
web feeds
is easy
Let's do
something
more interesting
Let's
aggregate
web feeds
We'll need
some
software
Planet
Give it
a list
of web feeds
It produces
a web site
And another
aggregated
web feed
Planet
is written
in Python
That's a
problem for
some people
Perl could
do that too
right?
Enter
Plagger
Typically
flashy
Perl project
web site
Plagger
does everything
that
Planet does
But it does
so much
more as well
I wanted
something
simpler
Something
closer to
a Perl version
of Planet
So I
wrote
Perlanet
Yes
Terrible name
I know
(Perlanet
doesn't even
have a
web site yet)
But it does
everything that
Planet does
Give it
a list
of web feeds
It produces
a web site
And another
aggregated
web feed
I use it
to build
planets
Planet Balham
got me
thinking
London is
a big city
But many people
have little
connection
to their
neighbourhood
After reading
Planet Balham
for a few weeks
I felt
more connected
I built
more
local planets
Planet
Tooting
Planet
Clapham
Planet
Streatham
Easy to
set up
and configure
YAML
config file
Template Toolkit
for output
Single program
(crontab)
Many feed URLs
can be
calculated
http://news.google.com/
news/?q=balham
&output=atom
http://news.google.com/
news/?q=balham
&output=atom
Just the
query string
needs to change
Not a
foolproof
method
Chris Balham
Nebraska
Can set up
a planet
in less than
an hour
Good
starting set
of feeds
Google
news search
Technorati
blog search
Flickr
tag search
Other feeds
need local
knowledge
Local bloggers
Local
twitterers
MPs, MEPs &
Councillors
Local reviews
To do
list
Perlanet
uses
XML::Feed
XML::Feed
uses
XML::RSS
and XML::Atom
All four
modules
have bugs
Still
tracking
them down
Module bugs
vs
Broken feeds
The more
feeds we test
the more
bugs we find
And
(hopefully)
fix
Please
build
planets
Please
report
issues
Please
report
successes
