Yay – not only did the programme come out, but also registration for Linux.conf.au 2012 opened within hours of my last post – well done LCA team! And I’m now registered and paid and ready. Just need to sort out flights… its been a few years but I’m looking forward to it.

Looking forward to getting myself sorted for Linux.Conf.Au 2012 this January in Ballarat, Victoria. A heap of mini confs have been added before hand – now comes the problem of choosing between them.  Registrations were slated to open early september – hopefully soon, as I want to confirm my ticket and accomodaiton before booking flights… and they get more expensive as time passes. So, I guess everyone is watching the LCA web site intently!

May have a few days in Melbourne afterwards with my Mrs and son… we’ll see. 😉

If you’ve not seen any of the PLUG news, then you may not know that PLUG is organising for Rusty Russell to come to Perth for our October presentation. This is the first time that PLUG has flown a speaker in to Perth, and if successful, probably wont be the last time! The cost of doing this is being split amongst attendees by way of ticket sales at $20/member, $50/non-member (and PLUG membership is $20/full, $10/concession, so you can work out what’s cheaper!). In order to help us with out budget, door sale tickets on the night will be $50 for everyone, so please get your ticket now (details).

On top of this, free tickets are being given to UWA 3rd year Comp-Sci students… except… PLUG committee has just voted to extend this to all full time tertiary computer science students at any university. You still need to get a ticket – email tickets@plug.org.au to request one. This event will be on Tuesday October 11th, starting from 6:30pm (doors open 6:00pm).

For those unable to attend, PLUG will again be endevouring to live-video stream the session, and make the recording available afterwards.

I use Florian octo Forster’s fantastic parrallel ping library liboping, and over the last 9 months or so have contributed a few minor bug fixes (mostly build related stuff, so not exactly core to the library’s code). I use this for doing parallel pings of hosts and gathering stats, as part of a wider heuristic for site web speed. Of course not all hosts respond to ping, but thats fine; some do.

I went to build vresion 1.6.1, and found that it installed into /opt. This was from source as I was on a platform that is not Debian (otherwise I’d just use the package and be done with it). I found that by default, everything had been put into /opt. I prefer using /usr/local, so I built it with:

./configure --prefix=/usr/local && make && make install && make install-data

The reason for the last one is that I want the headers installed. I then want to make the Perl library; and for that I need the linker to be able to find the library. I found that I need a file in /etc/ld.so.conf.d/ that lists this location, so along came “echo /usr/local/lib > /etc/ld.so.conf.d/usrlocal.conf“, followed by a quick ldconfig run to update the paths. I could then cpan -i Net::Oping.

Why blog this? Because every few months I have to try and remember it. Now I just need to remember that I blogged it.

With thanks for Florian octo Forster for the library, of course.

The time has come! The Perth Linux User Group is holding a Quiz Night tonight (doors open 7pm, Quiz starts 7:30pm), with questions very much based upon Linux & Open Source. It’s at The Moon & Six Pence in Murray Street. We’ve got a few prizes, and it’s free (through we’ll probably make you feel guilty if you’re membership isn’t 100% up to date ($10/yr)!!). Come share a drink and a laugh.
