This week I’m at linux.conf.au, the southern hemisphere’s premier open-source conference. This year it is being held in Ballarat, about an hour’s travel from Melbourne. I’ll be documenting the trip and conference as much as I can given the limits of my enthusiasm and awakeness.

Sunday 15th January:

Yay! My favourite mode of transport!

Sunday was spent travelling. My flight from Hobart to Melbourne departed at 8:35am, and it was a perfect day for flying. Warm, clear skies and little wind. An almost perfect flight. I landed in Melbourne before schedule and caught the SkyBus into the city. I was there by 10am, and my train to Ballarat (which I was travelling with my friend Michael Wheeler on) left at 5:08pm, so I had quite a number of hours to spare. Needless to say, I did what any tourist would do, and set about travelling on as many forms of public transport as I could in one day.

The View From St. Kilda Pier

I caught a tram down to St. Kilda, the light rail (which was merely a glorified tram) back, a suburban train out into a random suburb and back, as well as the plane, car and bus I had already travelled on. I took a few pictures, mostly from St. Kilda pier. A poster detailing the risks of getting in the way of a tram also caught my eye.

A rhino on a skateboard? Sure...

After my random adventures in Melbourne’s transport system came to an end, I met Michael (fresh from his trip down from Rockhampton) and we proceeded to get on the VLine train to Ballarat. We fired up our laptops and were just getting comfortable in a game of OpenTTD, and then the train was off! But not for long. After about 200 metres of travel it was announced that the train was cancelled, and we would all be transported on coaches instead. We finally arrived in Ballarat two hours late, at about 9pm.

This summer, like last summer, I’ll be travelling to linux.conf.au. This year it’s being held in Ballarat, which presents the opportunity for one of my favourite modes of transport: TRAIN! Here, tentatively, are my plans for that week:

• On Sunday the 15th I’ll awake early, catch the 8:45am Jetstar flight from Hobart (HBA) to Melbourne Tullamarine (MEL). That arrives at 10:00am. I’ll then make my way into the city, have lunch at a trendy café with friends from Melbourne. I will then catch the 3:08pm train from Southern Cross Station to Ballarat. My good friend Michael Wheeler will join me for that leg of the journey. I will then be in the conference city, ready for finding all the cool people to annoy.
• I will stay at the on-campus accommodation, for maximum NCSS-style bonus points.
• I will attend the Penguin dinner.
• The next Saturday (the 21st) I will do the same journey in reverse. I don’t have lunch plans that day, so if you’d like to catch up in Melbourne (and prevent me from spending all my money in stationery shops) let me know!

I’ve also recently re-installed Debian on my laptop. Running Windows 7 last conference was embarrasing. I ran PuTTY full-screen the entire time just to cover up the fact.

I hope to see you all there!

My friend Michael Wheeler has written an excellent article on the whys and hows of removing your data from the cloud. This post is basically just to point you all towards it.

Over the last few years I’ve been in a similar process, getting rid of my Google account and hosting my own email. I’ve attempted to get rid of Facebook, and learned a lot about myself, my friends, and Facebook in the process. I now no longer have twitter (again) and I’m just generally being a lot more careful with my data.

I think everybody will benefit from thinking just a little more about where their information goes, so I highly recommend you read this article.

Today was the first proper day of linux.conf.au, which is being held this year in Brisbane. This morning we were treated to a welcoming speech by conference organiser Dr Shaun Nykvist, and a presentation on the Google Summer of Code happening this year. In the welcoming speech, Shaun detailed how the organisers and volunteers had to work against water and time to get the conference ready despite Brisbane’s horrific flooding:

“I’ve got some lovely photos of our old venue with sandbags against the flood zones. It’s a shame the sandbags were about three metres lower than the water.”

After morning tea (some very lovely cakes and biscuits were provided) it was time for the Miniconfs. During the morning session I attended the Open Programming Miniconf, organised by my friend Chris Neugebauer. The first talk was about perl5i, which is a package of library modules for perl that makes it an almost usable language (almost, I don’t think that there is anything can truly save it). It was very interesting stuff, seeing how the syntax and semantics of a language can change. The speaker (Michael Schwern) was brilliant as well, which is always nice.

The next talk was about the F# programming language, designed by Microsoft. Brian McKenna’s speaking wasn’t great (but it was his first big talk, so that can be forgiven). Although I dislike the idea of languages that run on top of runtimes (such as JVM and .NET), F# looks like a good invention. Indeed, it’s basically where Microsoft develops and tests features that might be useful to put into C#.

After that was a talk by Brianna Laugher on generating English-language text using software tools, from a set of data. She was using it as part of her job at the Bureau of Meteorology to automate the generation of weather reports from their models. The idea was hugely interesting, and something that I want to implement. However, I didn’t really understand how the generation itself worked… quite a few arcane symbols seemed to be in use. I think I got the general gist though.

The final talk before lunch was about Go, the programming language developed at Google. I originally thought Go was a programming language for children, but I’ve now been set straight. It looks like something to test out… which is being added to my very long list of stuff to try now.

After lunch I went to see two talks from the Haecksen Miniconf. The first was about how open source software can help save the world, mostly by developing open source software to fix natural disaster problems, and doing it really really quickly and cheaply. The second was about setting up an overly-complicated home network, an area with which I am well acquainted.

Then it was back to the Open Programming Miniconf, where I learned about the demise of Java (basically, the Java community is dead, but Java itself will probably survive, and the JVM will definitely survive). The final talk before afternoon tea was about how to create compilers for the JVM using a parser written in Scala. Unfortunately due to the use of Scala I lost most of the detail of the talk, it went straight over my head. Which is a pity, because I was really looking forward to that talk. Ah well, guess you can’t win them all. After all this though, I was really interested in designing programming languages and compilers. I might have to give it a go.

During the final session of the day I was treated to a brilliant talk by Adam Harvey, who is a PHP developer (i.e. actually develops the PHP interpreter) telling us about the state of the PHP language. It seems Debian Stable is hugely out of date… but this is nothing new. He’s a great speaker, and I look forward to hearing his talk tomorrow, even though I don’t know what it’s about.

Last up was Jethro Carr, a hacker from NZ I know from attempting to complete his 30 Days of Geek challenge. He talked about the software revision control management tool thing he wrote, and talked about the benefits of using such software. Personally I quite enjoy using Redmine, but it’s requirement for Ruby means that I might be looking for an alternative when I get around to setting up my own installation. Currently I use the Quokforge service, run by one of my friends on OSDev.org.

So that was day 1. Or rather, the official day 1. Since then I’ve bought a printer and been to an Irish pub. More LCA news coming tomorrow, I hope.

Yesterday was day 0 of my adventure to linux.conf.au in Brisbane. I woke up extremely early (5:15am AEDT, which is 4:15am AEST) and caught a flight to Sydney and then on to Brisbane. I caught the AirTrain into the city (which is awesome, so much better than any other capital city’s offering) and met my friend Michael to drop off my bag at the hotel. After catching up with my sister for lunch (she lives in Brisbane) I headed off to the venue for the conference, QUT in Kelvin Grove.

I sat around with a few of my friends from the ##australia IRC channel on Freenode, while discussing the conference’s preperation on #linux.conf.au on Freenode. After a while, I went and registered for the conference, and got some awesome swag. The item of note is a Yubico Yubikey, which seems to be a really awesome solution to the password problem.

After the registration, I went with a few of the other ##australia geeks to get pizza from a local place in Kelvin Grove. It was a lot of impromptu fun, especially when a few more geeks from linux.conf.au showed up and also had a bite to eat.

After the pizza, it was back to the conference venue for the “noobie’s talk” which introduced us to what happens this week. In short, it sounds like a lot of fun. The presenter of the talk, Rusty Russell, has a great sense of humour. We then went off to the pub with the other first-time attendees, but we didn’t stay long because it was loud and we went off to something better.

Most of the attendees are staying at a place called Urbanest, which looks like an interesting place, mostly because of the density of geeks. Last night I went up to Urbanest for an hour or so, and watched the cricket and talked to a few other geeks. I met Jethro Carr, a geek from NZ whose blog I read. I then retired for the night, because you can only be awake for so long without a drip of caffeine.
