Recently, I tried to get 3G working on my Lenovo ThinkPad X121e - it has an Ericsson F5521gw mobile broadband card. This is supported by ModemManager, but all I got were unknown errors (276 and 272).
Searching online, there were very few results (hence this short note) - just previous unrelated Linux kernel issues. I found someone with the same problem on Fedora, but no solution, so I started off by filing a bug report with Debian.
Of course, then I found the Arch user who had filed the same bug on Launchpad, and had discovered that resetting the BIOS to its default settings fixes the issue. If only that page mentioned the keywords "Ericsson", or "Lenovo"...
So after all that, it was just some weird BIOS issue. I hate hardware.

So since my last post about perl tutorials, the Perl Tutorial Hub has leaped from page 2 to be the top result for the relevant Google search. The Leeds tutorial has dropped off the first page.
I couldn't figure out how such a dramatic reversal could have happened, until I asked Mithaldu on IRC; the admins of the old Leeds tutorial have added a (delayed) redirect. So, Google has interpreted that as a 302 status, and given perl-tutorial.org all the old inbound links, presumably.
Perhaps there is hope for Perl yet. :)

Last year, a bit of a fuss was kicked up in the Perl community about the low quality of search results for the phrase "Perl tutorial". Various ideas for fixing this were proposed, including the handy Perl tutorial hub, but kicking Leeds University off the coveted top spot is going to be a real challenge.
The problem is, most Perl tutorials on the internet were written for Perl 4; modern Perl doesn't get a look-in. It's a miracle anyone manages to learn Perl at all...
While thinking over this problem, I was reading Mithaldu's original criteria for the "content creation" option. "Community effort"... "github repo"... "exported to HTML regularly"... if only Perl had some central site where you can publish documentation... that all Perl hackers can access and update... like CPAN.
So although my documentation-writing skills are pretty weak, I proudly introduce the Perl-Tutorial CPAN dist and github repository. The great thing about writing Perl documentation using POD is that you can link to other CPAN references so easily - as the basics get filled out, they can guide the user towards how to learn more about each topic. Everyone who's anyone knows how to send a pull request on github, and there seems to be far more of a community feel to CPAN these days.
Version 0.001 is just "Hello, World!" - but watch this space. :)
