The speakers' dinner is our opportunity to thank all of our wonderful speakers for their part in making this such a wonderful conference. The Floating Pavillion, sitting right on Auckland's world-famous Viaduct Harbour has a wrap-around covered deck from which you can view our beautiful Auckland sunset while listening to a young local band and mingling with your fellow speakers.
Penguin Dinner at MOTAT, Wednesday, 14th January from 6pm.
This year the steam-punk themed Penguin dinner will be held at Auckland’s MOTAT (Auckland's Museum Of Transport And Technology). With its traction engines, Victorian village, trams and trains makes it so easy to imagine Jules Verne or HG Wells wandering around creating their stories of futuristic wonder!
If getting dressed up in Victoriana or Steapmunk is your thing then this is the place! We’d love it if you’d like to dress in costume and show off your gadgets for the occasion, the more quirky and fantastical the better! It adds a certain air to the evening, however it is not mandatory.
MOTAT is a local favourite equipped with great facilities in a unique location, so we can be sure of a night to remember!Professional Delegates Networking Session (PDNS) at Sweat Shop, Thursday, 15 January from 6.30pm.
The PDNS is being held at the newly-renovated Sweat Shop - a micro brewery with a philosophy around championing its staff - claiming to be Auckland’s hardest working bar. This destination mega-venue boasts one of Auckland’s largest outdoor decks and garden bar that really sings in the summer.
For the PDNS LCA 2015 will be taking over the venue for the whole night, so we will open the bar to all of our delegates after 8.30pm. UPDNS welcome!
Please see our Events Page for more information.
Zoe slept all night, which was nice. She woke up at like twenty to five, needing to go to the toilet, and afterwards claimed that she'd checked for Santa and he hadn't come yet. I thought the jig was going to be up for sure, given that the presents were all out.
I managed to get her back to bed and she slept until 6:30am, which was a much more civilised time to be opening presents.
After opening presents, and breakfast, Anshu prepped the dish she was taking for Christmas Day lunch at my parents, and we headed over there.
My sister called and asked me to get some ice along the way. 7 Eleven were obviously anticipating a run on ice, because they had multiple insulated pallets of party ice bags. It was slightly crazy.
We had a nice Christmas Day lunch with my entire immediate family, which was a bit of a first since I've been back in Australia. Zoe got along really well with one of my brother's step sons, and generally had a good time.
After lunch, we headed down to Palm Beach for a quick catch up with some more family. Zoe had a nap along the way, and then we headed back to drop Zoe off at Sarah's place.
Anshu and I went back to my place, and we went for a nice evening stroll to walk off the Christmas lunch.
I didn't have an awful lot planned for the day. Zoe finished watching the Nightmare Before Christmas, after she was dropped off, an then we made a bunch of dips for Christmas Day lunch.
Zoe really enjoys helping me in the kitchen, and today was no exception. She also has taken to helping with the washing up, and loves putting on my washing up gloves, so we made all of our dips together, and then she lost interest when it came time to make the plum pudding, so I did that myself.
Kelley had told me about a Christmas pantomime called Spaced Out Santa, on at the Studio Theatre and Cafe over at Morningside. I didn't’t even realise there was a theatre over there. They had tickets, so I thought that’d be something different to do.
We biked over there, via the post office, so I could deposit an offline donation I'd received for Decembeard.
We got to the theatre pretty early, and the "cafe" part of it was rather tiny, but we managed to snag a table. We had a drink and a snack while we were waiting for the theatre to open.
The theatre itself turned out to be not a lot bigger than the cafe. It was probably about 10 seats wide. We managed to get into the second row from the front. The play itself was nothing spectacular, but Zoe seemed to enjoy it. Most of the actors were children, and I thought they did quite a good job. It was hard to tell if the singing was lip synced or not.
Zoe was hungry by the time we got out, so after some photos with the actors, we grabbed some lunch nearby and then biked home.
I can't remember what we got up to in the afternoon, but Anshu came over, and we had some dinner, and then Zoe got all ready for bed, and we went for a drive around the neighbourhood to check out the Christmas lights. It was really nice driving around with some Christmas music playing on Pandora. I really like the Bing Crosby channel. It really helped set the mood.
Zoe has been super excited about Christmas this year. She's been counting down the sleeps until Christmas, and was very excited to leave out some egg nog, a mince pie and a cookie for Santa, as well as some water and carrots for the reindeer. I had just as much fun making them all look eaten. It really is a lot of fun looking at Christmas through the eyes of a child.
There are a few preferences to check in about:config:
- media.peerconnection.enabled should be true
- network.websocket.enabled should be true
- loop.enabled should be true
- loop.throttled should be false
If you use the popular NoScript add-on, you will need to whitelist the following hosts:
If you use the less popular but equally annoying RequestPolicy add-on, then you will need to whitelist the following destination host:
as well as the following origin to destination mappings:
- about:loopconversation -> firefox.com
- about:loopconversation -> mozilla.com
- about:loopconversation -> opentok.com
- firefox.com -> mozilla.com
- firefox.com -> mozilla.org
- firefox.com -> opentok.com
- mozilla.org -> firefox.com
I have unfortunately not been able to find a way to restrict tokbox.com to a set of (source, destination) pairs. I suspect that the use of websockets confuses RequestPolicy.
If you find a more restrictive policy that works, please leave a comment!
- Lounge-24-Dec-14 overlaps Chillout-4-Dec-14 because style is very similar at times
- Latin-and-Tango-4-Dec-14 has become Latin-Chillout-and-Tango-4-Dec-14

Been struggling with sound engineering of late. Have wondered whether or not it's simply easier to go for transiest shaper VST's across the board.
Someone questioned why it seemed easy for me to improvise. I was curious about this as well. I think for the most part it's been about listening to heaps of music since I was young.http://www.perfectpitch.com/perfectrelative.htm
http://www.pianonoise.com/Article.Simple_gifts.htmBeen having major struggles of late how to relate percussion to melody. The best music I've come across seems to have tracks and sections which blend perfectly into one another and where the relative complexity and tempo remains roughtly the same. A bigger toolkit (software or hardware) also helps. Look at work of 'Groove Armada', 'Artful Dodger', and 'Kaskade' and you'll understand what I mean.
A lot of software allows for automated scale selection (useful for me because I tend to select notes based on ear rather than selecting a key first). For those who don't who just prefer the old fashioned mechanism please consider the, 'circle of fifths'.
Think about use of Melodyne and Antares Auto-Tune for easier composition if you're lazy. Record whistling or singing as a 'WAV'. Import it into Melodyne and then convert the notes into MIDI for import into Ableton or other DAW software.
Some interesting stuff I've come across recently. Possibly worth reworking/remixing them (looking around for good stems for remixing but am willing to work with existing songs if necessary).
- Nice track but could have really done something with some note changes here and there. Strange use of panning at times, bit muddy, could have been clarified a bit in multiple frequency ranges. Could have done with master bus (or simply another layer) over the top to add some common effects to the overall track that are common to Latin and Tango tracks (Vinyl distortion, bitcrushing, equalisation, compression, etc...). Some sections don't blend into one another as a stronger song should, could be interesting for samples. https://www.youtube.com/watch?v=edHXUHTCvBI
- Great overall. Some beautiful sections but a little bit disjointed. Bridges (personally, currently struggling with this) into breakdowns use heavy delay, reverb. Breakdowns similarly awkward at times (feel and emotion is just way off). More active strings/harmonica in parts, realy bring out the best in the musician/clip/instrument in question. Rain effect possibly replaced with heavy vinyl distortion effect? Just strange with that muddied sound. Bring up velocity or mixing volume of the piano in some parts? Better use of velocity/dynamics in some parts. Could have used some light scratching in some sections and some glitching if you going for an Alternative Hip Hop and Latin feel to it, made more use of panning and other effects to create better atmosphere. The best tracks that I've come across you can often close you're eyes and you're sitting right in front of the ochestra or band itself. You can't do that here. Ripe for sampling or remixing. https://www.youtube.com/watch?v=bOYb9CV2qoQ
- Ripe for sampling/remix... Heavier percussion in sections. Overlay scratching in parts. Some glitching. Perhaps electrical guitar over top. Vinyl distortion, bitchrushing for greater character. Really bring out some instruments and dynamics of them... Aware that lazy feel is common to this particular style/genre of music though. https://www.youtube.com/watch?v=P2dFLlaEaIU
- Overall nice, downtempo track. Slow down vibrato/tremolo rate on some synthesiser sections. Suffering from distortion in the mix in the lower end bass and percussion area. Could have done with some extra complexity/variation in the percussion/synthesiser pad area. Am using monitor style headphones (Audio Technica ATH-M50X) so believe it may be the mix rather than equipment. Deals with high frequency harshness nicely. Feels like, low pass (or multi-band) filter, EQ, compressed, etc... Extra reverb plus some delay across the board on the bus to emphasise atmosphere? https://www.youtube.com/watch?v=mhskiBuoIiY
- Lacks oomph, character. A bit lost at times but that is particular to this genre. Greater dynamics across the board. Extra complexity on percussion, staccato shorter, more sincupated rim. Violin string section slightly more active at times. Clarify sound, enhance detail or is that just this particular copy? https://www.youtube.com/watch?v=4c1ngk41fm0
Interesting stuff from these guys (from a song that I found elsewhere). http://www.chilloutmusic.yolasite.com

I didn't have a lot planned today, except for showing my first customer my favourite food wholesaler at around lunch time, so after Sarah dropped Zoe off, we gave her free reign over what we did.
She said she wanted to go to the same park we went to last time, which I misinterpreted as Love Street park in Bulimba. So we set off on foot for the park.
It turned out she really wanted to go to the West End park again, which was fine, because we could go there in the afternoon after lunch. At the Love Street park, we ran into one of the boys who will be going to her school next year, who went to her day care last year, and one of the boys from her Kindergarten, so that was nice to run into some familiar faces. It was while we were at this park that I received the sad news that Bryce had passed away.
After a bit of a play in the park, we walked back home again, and drove over to West End, picked up my customer, showed her the food wholesaler, dropped her back at work and then returned to the food wholesaler to grab a few bits and pieces and have some lunch.
After lunch, we went to the park at West End, and then we went back home again.
Anshu went home, and then I put the Nightmare Before Christmas on for Zoe, which she watched until Sarah came to pick her up.
Since I've been failing miserably to go for runs in the morning, I thought I'd try going for an evening run, so I did an atrocious 5 km run.

Zoe slept all night (for a change), which was nice.
We hadn't caught up with Chloe for a while, so I'd made plans with Kelley to spend the day at the Science Centre. Anshu was on Christmas holidays from work, so she tagged along with us as well.
We all caught the bus in, along with Chloe's older sister.
Before lunch, we all went to the Science Centre, and after lunch, we did the rest of the museum. The girls had a good time together, and Zoe seems to get along well with Chloe's older sister, Emma too, which is nice.
Kelley had to go to the Valley to get some stuff, so we parted company at the bus stop and took the bus home.
Laura dropped by with Megan and her little sister, not long after we got home, to drop off a Christmas present for Zoe from Megan, so the girls did a gift exchange and had a little play date.
They left just before Sarah arrived to pick up Zoe, and Anshu and I took a walk down to Bulimba to check my post office box, and we discovered a new watering hole on Oxford Street, so we had a drink on the way back home.
I received a sad phone call this morning, while we were at the park.
It was from Bryce's son, Russell, and he informed me that Bryce had had a fall and hit his head yesterday morning, and not regained consciousness before passing away today.
It was a bit of a shock for me, given I'd only seen him on Monday of the previous week, and I'm so grateful that I did, because it had been several months since I'd last seen him.
He was particularly weak and wobbly on his legs, so the fact that he had a fall wasn't particularly surprising, and in a lot of ways, it was a small mercy that he had a quick and presumably painless demise.
He made it to 91, so that was a pretty good innings.
I know he was looking forward to spending a few days with his family over Christmas, so it's a shame that he didn't get to have one more with them.
deb http://www.coker.com.au wheezy wordpress
The above repository has the wordpress-wp-spamshield package for Debian/Wheezy. I have no immediate plans for uploading it to Debian because the security support for WordPress plugins doesn’t fit in with the Debian model. I am prepared to negotiate about this if someone has good reasons for including it or any of the other WordPress plugins I’ve packages.
My packaging work is under the GPL (of course) so any DD who disagrees with me could just rebuild the package and upload it. Within Debian there is no rule taking another DD’s GPL’d code that they decided not to upload and then uploading it. There is a consensus that such things are not appropriate without permission, but anyone who wishes can take this blog post as permission.
Inside the IBM POWER8 chip there’s another processor! That’s right folks, you get another CPU for no extra cost (It’s a lot funnier if you say these previous two sentences as if you were presenting an informercial for a special TV offer).
It is, however, not what you’d consider a general purpose processor. It is, in fact, a PowerPC 405 – so your POWER8 processor also has another PowerPC chip in it. What’s the purpose of this chip? It’s named the On Chip Controller and it has the job of helping make the main processor (the POWER8) work.
It has two jobs:
- Monitor temperature and keep the system thermally safe
- Monitor power usage and keep the system power safe
It runs a hard Real Time OS which has just been released up on github.com/open-power/occ
It’s fairly exciting to see more of the software that runs on every POWER8 system make it out into the world.
For those who love their system's uptime it is a sad moment when a power outage causes your system to go down after months or years. Worse still, on a reboot, you discover that your time is out by a hour, courtesy of daylight's saving time. Which is fine in itself, but it would be a better world if we all just used UTC. But that's another argument.

I trek out to a fairly dark sky site on the odd Friday evening to partake of some amateur astronomy at an observatory in the Dandenong ranges.
A few weeks ago, we decided to have a go at locating what was then a fairly dim object, C/2014 Q2. We found it with binoculars and in a relatively small (10") telescope. I'd just gotten a tripod-mounted motor drive for my DSLR, so of course we decided to have a go at imaging the comet.
I don't really have a great zoom lens (although), so instead I decided on the 50mm f/1.8 lens. That lets in a lot of light, which is handy when you try to photograph dim objects in a dark night sky and you need to find them in the viewfinder :-) Even with its wide angle though, you still need a motor drive to avoid stars turning unto lines ony any exposure longer than about 10 seconds.
This past weekend it was nice and clear and so I went back to the observatory, where I was able to take another photo of the comet.
And with two photos of an objects that moves across the sky fairly fast, it's of course time for an animation! I've annotated the brightest stars and a few open clusters down the bottom of the image.
I used GIMP to process the levels and colour balance for both images, so they approximately matched (the moon was out when the first image was taken on Dec 12) and then to rotate and stretch the second image to align with the first one. It's not perfect, but it'll do I think.
In fact, there are a few multi-pixel size blotches that seem to be present in one image and not the other, as well as some that move by more than the half-pixel or so that image alignment is out by.
Some are likely artefacts and noise, but I can't help but wonder if some are asteroids. I've checked against the ten or so thousand largest and/or most visible asteroids, but none of them are anywhere near.
I suppose I should get a third image in another week or two... to be continued?Tags: cometastronomyphotographyprocessing

- I never thought I’d be feeling safer here in Cambodia than back home in Sydney 21:10:44, 2014-12-15
While it sounds like I should really switch to a bookmark-based Mercurial workflow for my Gecko development, I figured that before I do that, I should document how I currently use patch queues and Bitbucket.Starting work on a new bug
After creating a new bug in Bugzilla, I do the following:
- Create a new mozilla-central-mq-BUGNUMBER repo on Bitbucket using the web interface and put https://bugzilla.mozilla.org/show_bug.cgi?id=BUGNUMBER as the Website in the repository settings.
- Create a new patch queue: hg qqueue -c BUGNUMBER
- Initialize the patch queue: hg init --mq
- Make some changes.
- Create a new patch: hg qnew -Ue bugBUGNUMBER.patch
- Commit the patch to the mq repo: hg commit --mq -m "Initial version"
- Push the mq repo to Bitbucket: hg push ssh://firstname.lastname@example.org/fmarier/mozilla-central-mq-BUGNUMBER
Make the above URL the default for pull/push by putting this in .hg/patches-BUGNUMBER/.hg/hgrc:[paths] default = https://bitbucket.org/fmarier/mozilla-central-mq-BUGNUMBER default-push = ssh://email@example.com/fmarier/mozilla-central-mq-BUGNUMBER
I like to preserve the history of the work I did on a patch. So once I've got some meaningful changes to commit to my patch queue repo, I do the following:
- Add the changes to the current patch: hg qref
- Check that everything looks fine: hg diff --mq
- Commit the changes to the mq repo: hg commit --mq
- Push the changes to Bitbucket: hg push --mq
Since I have one patch queue per bug, I can easily work on more than one bug at a time without having to clone the repository again and work from a different directory.
Here's how I switch between patch queues:
- Unapply the current queue's patches: hg qpop -a
- Switch to the new queue: hg qqueue BUGNUMBER
- Apply all of the new queue's patches: hg qpush -a
To rebase my patch onto the latest mozilla-central tip, I do the following:
- Unapply patches using hg qpop -a
- Update the branch: hg pull -u
- Reapply the first patch: hg qpush and resolve any conflicts
- Update the patch file in the queue: hg qref
- Repeat steps 3 and 4 for each patch.
- Commit the changes: hg commit --mq -m "Rebase patch"
Of course, feel free to leave a comment if I missed anything useful or if there's a easier way to do any of the above.
I am pleased to announce the linux.conf.au 2015 OpenStack miniconf programme. This will appear on the main conference schedule as well, but I am posting it here so I can provide the talk abstracts as well.09:00 – 10:00 Main conference keynote by Eben Moglen 10:00 – 10:40 …morning tea… 10:40 – 11:00 Welcome by Michael Still
Welcome to the OpenStack miniconf. This talk will outline the plan for the day, and then briefly introduce the various components of OpenStack to be covered for those who haven’t seen them before. 11:00 – 11:30 Deploying OpenStack Using Containers by Angus Lees
Traditional OpenStack deployments typically use dedicated and static “controller nodes” and “network nodes” deployed onto bare metal servers. This talks discusses some of the limitations with this approach and describes more flexible alternatives using containers, LXC, docker, and kubernetes. No prior knowledge of containers is assumed. Note this is *not* a talk about exposing containers-as-a-service to users via OpenStack. 11:30 – 11:35 …five minute break… 11:35 – 12:00 Introducing OpenStack Swift by John Dickinson
Swift is the OpenStack object storage system. It’s perfect for unstructured data like backups, server images, documents, and media. Swift is built for scale (including global deployments!) and handles all the placement, durability, and failure conditions so applications don’t have to worry about it. This talk will introduce Swift, as well as covering all the things the Swift PTL wished people knew before they deploy Swift for the first time. 12:00 – 12:20 Juju Deployments at Canonical by Brad Marshall
This talk with cover a brief history of Openstack deployments at Canonical and show how it has changed over time. It will focus on our current deployment methodology using Juju and MaaS, and the HA features we are taking advantage of. 12:20 – 13:20 …lunch… 13:20 – 13:45 Deploying Nova by Michael Still
Nova is one of the most commonly deployed components of OpenStack, as most installs want to provide access to compute resources. This talk by the Nova PTL will cover the various hypervisor options, what instance storage backend might meet your needs, and all those other decisions you need to work through when deploying nova. 13:45 – 14:10 Introducing OpenStack Neutron by Mark McClain
Neutron is the OpenStack networking component. It is responsible for creating tenant networks that separate traffic between tenants, as well as advanced features like load balancing and VPN as a service. Neutron is incredibly flexible, which comes at the cost of some complexity. Join Mark the former Neutron PTL as he walks through the
deployment options available to OpenStack users. 14:10 – 14:15 …five minute break… 14:15 – 14:40 Extending Horizon to work in your Deployment by David Lyle
Horizon out of the box doesn’t fully meet the needs of a running cloud and looks rather generic. Product managers complain that Horizon’s base theme does not meet corporate guidelines and administrators complain that they need more tools to manage the cloud. How does Horizon help solve this?
One of the main tenants of the Horizon program is extensibility. There are several established ways to get custom content into Horizon depending on your goals. External extensions, template customization and custom stylesheets can meet most customization needs.
The talk will present these methods for adding custom content and updating the style, point out the potential pitfalls, and share knowledge as a Horizon developer and a Horizon deployer.
14:40 – 15:00 Handling RabbitMQ Failures Gracefully with HAProxy : Sachi King
Almost all communication between services in OpenStack transverse though a message queue. The current default is RabbitMQ.
The RabbitMQ implementation in OpenStack currently lacks support for both Heartbeats and TCP Keepalive. Without these features, the RabbitMQ clients do not reconnect on failure, thus resulting in a complete API outage.
This talk will cover how we worked around this limitation to allow for graceful recovery on failure with HAProxy. While there are many ways to architect HAProxy in the RabbitMQ path, we’ll touch on what worked, and what did not.
15:00 – 15:40 …afternoon tea… 15:40 – 16:30 Selling Mist: Better Metering Through Ceilometer by Sharif Olorin
Recording usage measurements with high resolution and granularity provides many advantages for both public and private OpenStack deployments. External customers are happier because they know what they’re being billed for. Internal customers are happier because they can receive immediate feedback on efficiency improvements. System
operators are happier because they can diagnose problems more effectively, get woken up less frequently and be more confident about who to cluebat when they do.
Achieving this at scale with Ceilometer is nontrivial without sacrificing either data longevity or resolution. This talk presents one solution to the problem of storing high-resolution metrics from OpenStack over the long term using the Vaultaire time-series datastore. I’ll talk about the architecture of our metering system, a few of the challenges we faced getting this system into production, and what we learned from doing so.
Finally, I’ll talk briefly about the Gnocchi time-series-database-as-a-service project, why I think it’s awesome,
and how we at Anchor intend to integrate it into our OpenStack architecture.
