Going to linux.conf.au (again, finally)!

I'm very excited to be able to report that I'll be attending linux.conf.au again this year, first time since I left Australia.

By a happy coincidence, we'll already be in Brisbane during the week of linux.conf.au, so it was a bit of a no-brainer. The last time it was in Brisbane was the first linux.conf.au I went to.

Tangentially related, Valerie Aurora has just announced the publication of a conference anti-harassment policy. I've never heard of any inappropriate behaviour at linux.conf.au, but as a past organizer (of the 2005 conference) I think it would be a very positive thing if it adopted this policy anyway. Based on what I just read in the LWN article, The dark side of open source conferences, it would probably help attract more female delegates if they knew that the conference held a specific position on sexual harassment.

Yes, those lca2005 papers are mostly available

Martin and Mikal jumped the gun slightly and have mentioned that the papers from the conference are available. I'm actually in the final stages of extracting the last remaining ones from a few speakers who haven't coughed up yet (you know who you are).

I was suggesting Steven hold off announcing to lca-announce until such time as the majority of the papers were up, so people wouldn't have to keep checking back for the one paper that wasn't there yet, but was wanted.

Oh, and while you can browse at http://lca2005.linux.org.au/Papers, the papers are also linked in from the conference program pages, which may make finding a specific paper easier.

Well, that happened... (or reflections on the conference from a delegate's point of view)

Okay, now that I've braindumped about organisation stuff, I'll braindump about the conference in general (what I experienced of it).

The (warm body) networking was the best part for me (again). It was terrific that so many overseas Debian and Canonical/Ubuntu people were here this year (or was it just that since LCA 2004, and probably more importantly, Planet Debian, I recognise more names?). It was great to meet for the first time Scott James Remnant, Colin Watson (who has a totally awesome accent), the much maligned James Troup (who I didn't get an opportunity to buy a beer), Mako, Matthew Garrett, Matt Zimmerman, and probably a whole bunch of other people that I've forgotten to mention.

One of the definite highlights for me was the opportunity to have a one-on-one chat with Mark Shuttleworth. He is one exceptional person. He's got himself one metric spankload of money, but he's doing some really good stuff with it, rather than just pissing it up against the wall being an uber-rich dude.

He laid out his vision (and it really is visionary stuff) for where he wants to take Ubuntu and what he wants to do, and I was really impressed with the breadth, depth and clarity of what he had to say for himself. He knows exactly what he wants to do and how he wants to do it, and he's got the money to make it happen. Totally inspirational stuff. As I have said before, I think I need to jump on the Ubuntu bandwagon.

I also made his talk about going to space, and that was truly amazing. Again, here was a guy with a metric spankload of cash, and rather than just paying his way into it (granted, he did part with a wad of cash to get in) he went through all the rigorous training, and really became a cosmonaut, complete with a mission to accomplish while he was up there. I really don't think "space tourist" is a terribly accurate definition for him. From the sounds of it, it took some real determination on his behalf to get to where he got. He told his story really well, and you can tell he really enjoys talking about it. I hope that one got video recorded successfully, as I really want Sarah to see it.

I didn't catch a lot of Eben's talk, which was one I really wanted to catch, because I was running around trying to deal with drinks for lunch, which had been overlooked. Everyone was raving about him and his talk though, so that's another one I hope I can catch on video.

Unfortunately I didn't see a lot of what I really wanted to catch, which was the Debian Miniconf. I came in the tail-end of Mark Shuttleworth talking about Ubuntu and Debian. I suspect it was a similiar spiel to what I'd had when I spoke to him earlier, so hopefully I didn't miss too much. There was just too much initial registration stuff and general firefighting to do to allow me to have the first two days totally not doing organisational stuff. Oh well. I should have seen that coming.

I caught bits and pieces of Ted Ts'o's Recovering from Hard Drive Disasters tutorial, and what I caught was pretty cool. I missed the Bitkeeper part of Tridge's keynote, which was right towards the end, because I was doing morning tea preparation stuff, but based on some of the media coverage, it sounded interesting. Hopefully that one was recorded okay as well. I think I caught bits and pieces of Jeremy Allison's CIFS to the UNIX Desktop talk, but kept getting dragged out to attempt to deal with the issue whereby some flog was running a rogue wireless access point, and doing all sorts of nasty man-in-the-middle attacks on people. That really pissed me off (the fact that someone came to the conference and did that). Unfortunately due to the nature of wireless LANs, we really couldn't do a lot about it, but there was a small lynch mob of geeks (myself included) running around for the remainder of the day running iwlist scan on their laptops non-stop, attempting to get a whiff of the bastard again.

I was really looking forward to JB's talk about Asterisk. As it turned out, I had done my RHCE course with him last year in Brisbane (small world). The talk was disappointing. JB was an inexperienced speaker (but it is good to give those types an opportunity to improve) and his talk wasn't technical enough, and a lot of people actually thought he was trying to sell Asterisk, and it was perceived as being too salesy.

I successfully caught all of Martin Pool's talk about Bazaar-NG, and it was really excellent. (I still don't have the whole GNU/Arch, tla/baz/Bazaar/Bazaar-NG thing 100% clear in my head though, not being a really big user of revision control systems).

I also caught all of the OzTivo talk, unfortunately not realising it was on at the same time as Marc MERLIN's talk about spam evasion with Exim. Fortunately I did have a bit of a chat with him at the Professional Delegate's Networking Session, and he's convinced me that I need to give Exim a thorough investigation.

Andrew Morton's keynote on Friday was good. I was really interested to hear what he had to say, but was having a bit of trouble catching everything from right up the back. Fingers crossed the audio was recorded successfully. He didn't use any slides so that's all I really need.

I caught all of Elizabeth Garbee's talk on Tuxracer. I was really impressed by her speaking ability. She was really confident, spoken extremely well, and was humorous. The content probably wasn't technical enough for LCA, but it was great to see a young woman presenting, and it was a really enjoyable presentation nevertheless. I'm glad the CFP guys selected it.

That was about the extent of the talks that I made it to.

I'm really looking forward to Dunedin, where I can socialise more and generally be a normal delegate again. In the meantime, I can get back to having a lifestudying.

Oh yeah, shutterbug Michael Davies took a whole heap of photos, which I'm currently hosting for him, and are proving quite popular.

Well, that happened... (or reflections on the conference from an organiser's point of view)

Phew! LCA 2005 is done, and I have to say that I'm personally fairly happy with how things went. There were a few things that we could have done better, but overall, I think it was a pretty rocking conference, which was Steven's main objective.

I figure now is a good time for a braindump, so stand back, here goes...

From an organiser's perspective (in the order they occur to me):

Waaaay too much pizza. The CLUG pizza guestimating algorithm clearly does not scale. We had something like 150 pizzas surplus to our requirements. The final batch of 100 that arrived went straight to Ainslie Village, where they were gratefully received, and about another 50 left over from the preceding 300 where dispersed around the campus of the ANU to random resident students and anyone else who happened to be in the right place at the right time. Oh, and we really didn't do a terribly good job of catering for the people with special dietary requirements. We went to the trouble of asking delegates if they had any when they registered, but didn't plan appropriate alternatives for the Saturday conference-provided pizza lunch, hence me making a rushed trip to the nearest kebab shop for half a dozen felafel kebabs for the vegans and the food^Wdairy intolerants.

Lightning talks fell off the radar. I think Steve thought that I was looking after them, and I certainly didn't think I was. They didn't even make the program, so they really got overlooked. We managed to shoehorn them into the program on the last day with me nominally coordinating them, but it was a bit too disorganised for my liking. I think they are a very important part of the conference, so they need to get factored in. Perhaps half an hour of them a day (first up, prior to the keynote?) would be a good way to do it in future.

Speaking of keynotes, giving away a laptop was certainly a great way to ensure attendance. Rob did a fantastic job of defragmenting the audience every day. I did find the latecomers, who insisted on clustering around the back rather than finding a seat, mildly annoying. The back rows of the theatres were also popular because the wireless coverage was better there. I had mixed opinions on whether people should be availing themselves to the wireless LAN during presentations, but everyone seemed to be doing it, so I guess go with the flow...

The birds of a feather sessions could have been advertised better. This was my responsibility. I had one delegate have a bit of a bitch to me at the Professional Delegates Networking Session about the sessions being too late and poorly advertised. I hope he email[ed|s] the feedback through to us so we get it straight from the horses mouth. I don't really know how we could have done that a lot better, scheduling-wise. I was keen on having 2 hour (maybe 1.5 hour would have been better?) BOFs, and with a pretty jam-packed program, this meant things had to stretch into the evening. The problem with this was that once people shot through for dinner, they didn't tend to come back again, so that realistically really leaves you with 9am until about 6 or 7pm at the latest, before people are going to want to run away and have dinner. I had 12 BOF slots, of which I think 7 I'd filled before the conference started by people emailing us. I wanted to preferably keep half the slots available for people to suggest topics during the conference, but I allocated the vacant slots to the later 2 hours, which I suspect is what the delegate I spoke to at the PDNS was pissed about. In hindsight, perhaps having them later in the week would have been better, however that would have required some serious rejiggery, because most other nights had something on, between the Penguin Dinner, and the PDNS. There was just a lot of stuff to try and cram in, and something had to give. Maybe running more BOFs in conflict with stuff would have worked.

The quiz show was a late addition to the program, and seemed very popular. It was a shame that it was up against the keysigning, with so many well-connected foreigners chosing to attend it over the keysigning.

The venue for the Penguin Dinner was a bit ordinary (mainly with respect to open space and audibility from the back of the room). We were a bit limited with where we could seat 500-odd people, within walking distance of the conference venue. I still think it was a fairly good night, even if I didn't manage to blow $2005 on a signed t-shirt :-) The food was pretty good in my opinion.

I think the conference venue itself rocked extremely hard (damn, that phrase is infectious). Having all the theatres in close proxmity worked well. Having it all in the one building was a definite bonus. The foyer ended up being big enough, even with the couches (and the couches were a brilliant idea).

The (data) networking was really good. I don't think anyone found the static IP addressing requirement humungously onerous. The proxy ARP problem that was bouncing MacOS X and Windows clients off the wireless LAN was a bit of a pain, but the fact that we could piggyback on the ANU's excellent wireless LAN was a real bonus. Bob did a fantastic job of getting a lot out of the ANU's networking guys. I think the terminal room was sufficiently good as well. Throwing a few PCs in there seemed to be well received, as they seemed to be in use most times I poked my head in the room.

I found the organisers' room was too far away from the action. It was good to go and chill out there, but the registration concession booth seemed to become the de facto organiser's room instead. That didn't seem to be a major problem though. I'm not sure how well patronised the speakers' and media rooms were. They appeared vacant the majority of the times I walked past them to go to the organisers' room (which wasn't that often).

Having ready access to a laser printer and laminator was bloody brilliant. I spent so much of the first couple of days just knocking up signage as the requirements popped up.

The slideshow in the theatres worked really well as an information dissemination technique (if I do say so myself). The technology we used to implement it was a little bit flakey (the theatre PCs were netbooted with a minimal Linux installation, and all ran svncviewer back to a central server, which had the desktop shared with rfb. If I'd had a bit more time, and done a bit more testing, I probably wouldn't have gone with something that shared the normal X desktop (or maybe a different VNC server that did), as it did some weird shit with what was exported via VNC if you switched to another virtual terminal. But it worked well enough. I had a lot of trouble finding a GNOME-based slideshow displaying app. I ended up using gqview, which was okay, but not great.

Some delegates seemed to be a bit grotty. Mikal lamented about finding apples cores under all the couches, to which I think Chris or Jeremy responded "those damn Apple users!". That was an amusing comment today. I think bins were in sufficient supply that there shouldn't have been as much mess as there was.

I think we overcatered morning and afternoon teas. I dare say LCA2005 will be forever known as the LCA where the delegates were stuffed with food to the point of popping. The coffee was good, and one of our main concerns (that we wouldn't be able to caffeinate enough people in the time alloted) was unfounded.

The cowbell worked well as an indication that the talks were restarting after the breaks.

Umm, I think my brain is starting to run out of things now...

But please, if you have some feedback, (positive or negative, but preferably constructive if it's negative) please email it to us.

I'm looking forward to attending LCA 2006 as a mere delegate again.

Twas the night before lca2005, and all through Manning Clark, nobody was stirring, not even a conference organiser

I started the day with a couple of airport pickup runs, picking up some Debian developers and dropping them at their accomodation. I also introduced Mako to Vegemite and Tim Tams, which I'm sure he'll be blogging about...

I'm really pleased with how things have gone today. We did our first batch of earlybird registrations (guestimates are about 20% of delegates registered this afternoon). The wireless LAN appears to be working, excluding a gratuitous ARP problem with MacOS X (it's a Linux conference, use Linux, dammit!) which I will Google for a solution shortly.

The slideshow is up and running in the theatres, and I have managed to get svncviewer playing ball with init, so I can remotely PXE boot the theatre machines and have them automatically VNC into the main server with the slideshow running on it (I can drive the whole gig from the couches in the foyer, very cool).

I think the couches in the foyer should be a big hit. They were certainly well patronised this afternoon by the delegates that turned up to register.

Bring it on, I can't wait. (But I'm glad to be at home getting ready for bed at a sane hour, rather than doing a million last-minute things).

Holy bags of schwag, Batman!

Have we got some cool schwag... We've just spent this morning doing the bag brigade thing and packed 500 bags with some very cool schwag if I do say so myself.

I'm impressed that we've managed to have the whole lot done before midday...

Now I just need to organise the printing of some signage, make sure all the lecture theatre slideshow stuff works, and I'll be feeling pretty happy with things.

Twas the week before linux.conf.au, and all was busy

I've had my own personal hackfest this week, and it's been fun.

First, I tried to get Debian going on an E450 for use as a desktop in the terminal room (as you do). This worked, but I ran into some unpleasant video problems. So I tried taking dilinger's Sargeified Ubuntu xorg packages and building them, which worked, but presented a whole bunch of keymap problems, so I wrote that off as a failure.

Next, I dicked around with the slideshow presenting solution for the theatres when there isn't a presentation on. We've hijacked the PCs that are part of the theatres, and are netbooting them with Linux, and then they're going to VNC back into a central server using svncviewer (so they're pretty minimal), which will run a set of slides (which I must create tomorrow).

The piece de resistance was the access point I helped Bob with today for the backpackers hostel to provide delegates staying there with some wireless Internet access (we're hoping more than one person is actually going to stay there so they can avail themselves of this).

It's a small cased mini-ITX box, with a PCI wireless card and an iBurst modem hooked up to it, running a bit of NoCatSplash (just because I could) (I can't believe this isn't in Debian?). It's doing transparent proxying. It's not that exciting, but I think it's cool because we've essentially made our own bit fat access point with extra functionality to suit our requirements.

Tomorrow I need to make the aforementioned slides up, figure out how to make up a BOF sheet in LATEX that doesn't suck, and do some general gophering. Probably thoroughtly test the backpacker's access point too.

Perfect weather for a conference

I took this week off work to help do finishing touches to linux.conf.au and the weather has been fantastic. I really hope it keeps it up for next week. If it does, the decision to hold the conference in April will have really paid off.

In the interests of timely information dissemination

This email should have gone out sooner, but it still going through the works, so to get the information out before delegates start unplugging and getting on planes and getting out of contact, here's a sneak preview:


With the conference less than a week away, we thought we should give you some
orientation information for when you get here, to help you find your way to
the Manning Clark Centre. Once you've registered, you will receive your bag
of schwag, which will include the conference handbook, which will answer any
further questions you may have.

This email contains:

* Directions to the Manning Clark Centre from all over the place
* Emergency contact telephone number
* Important note regarding delegate badges
* A reminder about the keysigning
* Current weather conditions

> Where is the Manning Clark Centre?

The MCC is building 26a, and can be found at 

How do I get to the Manning Clark Center from Burgmann College?

Burgman College is building 52 on

Walk out of the college onto Daley Road and turn left. Take the right fork
onto Sullivan's Creek Road. Keep walking. You should pass the Hancock
Library on your left and there will be a zebra crossing across Sullivan's
Creek road to a bridge over Sullivan's Creek. Walk over this bridge and
follow the path along the rear of the Chifley Library (with Fellows Oval on
your right). Take a left turn past the entrance to the Chifley Library,
keeping the A.D. Hope building to your right and you should see a ramp
leading up to the Manning Clark Center.

How do I get to the Manning Clark Center from the City (a.k.a. Civic)?

Assuming you will be entering the campus via University Avenue, walk down
the pathway keeping the Copland Building (building 24 on
http://campusmap.anu.edu.au/displaymap.asp?grid=ef32) on your right, until
you reach the University Union Building (building 20) and hang a right up
the ramp to the Manning Clark Centre.

How do I get to the Manning Clark Center from University House?

University House is building 1 on

Walk along Liversidge Street until you come to Ellery Crescent. Follow it to
the left, until it reaches a cul de sac outside Melville Hall (on your
left). This will lead you onto the same path beside the Copland Building
referred to in the directions from Civic above.

> Emergency telephone contact

If you get completely, utterly and hopelessly lost, ring 6125 8186 
(that's +61 2 6125 8186) and it will divert to an organiser, who will try
their best to direct you to the Manning Clark Centre.

> Delegate badges, more precious than gold

As you may have already learned, linux.conf.au has sold out quite a few
weeks before the conference. Because of venue restrictions, numbers are
strictly limited to 500. To ensure this, we will be checking delegate badges
throughout the conference. Make sure you wear yours at all times and do not
lose it. We will be charging a replacement fee of $50 to replace delegate
badges (after sighting satisfactory identification). Anyone found not
wearing a badge at the venue will be asked to leave.

Your badge is also your ticket to the conference dinner and the professional
delegates networking session (if you your registration includes these).

> Keysigning

If you are interested in taking part in the GPG keysigning party at LCA
make sure you submit your public key prior to Friday 15th. More
information and instructions on how to submit your key can be found at

> Weather

If you're wondering what to pack, currently it is a bit unseasonably warm,
with maximums in the mid to high 20 degrees (Celcius). There is rain
forecast for Friday, which may drop the temperature back a bit next week, so
you might want to bring a mixture of summer-type clothes (i.e. shorts and
t-shirt type stuff) and slightly warmer clothes (i.e. jeans).

See you soon!

I've just started having a flick through all the paper submissions, and boy, have we got some good sounding material. I can see some logical tracks forming. Can't wait for the next meeting where we finalise who's speaking.

Conference letterhead

So we look a tad more organised, I've knocked up some quick and dirty letterhead for written correspondence. It was my first attempt to really use OpenOffice, and I felt a bit like a fish out of water.

linux.conf.au (the domain) is back

Well it's been a few months in coming, but kre has finally delegated linux.conf.au back into existence. How kind of him.

Redhat gets on the conference bandwagon

The only thing I'm surprised about is how long it took them to get on the bandwagon. I have to wonder how sustainable this many Linux/FOSS conferences are...

Call For Papers spam

Tonight I sent mail to the SAGE-AU announce and Aussie-ISP mailing lists letting them know the CFP was open. I also emailed Carter Bullard of Argus fame to see if I could convince him to put a paper in the CFP.

LCA DoSes Subway again...

It's always amusing watching the denial of service effect of catering for an LCA committee meeting with Subway. Steve phoned the order through for collection at 6pm. I rolled up a few minutes after 6pm to see a lengthy queue and all hands on deck madly trying to make 9 foot long subs as well service the queue. Another 10 minutes later and the order is fulfilled. At least they gave me 6 double-choc cookies as a consolation :-)
