LCA day 4 – On freedom

By | Technical | No Comments

It goes without saying that Linuxconf is all about free software, as in both beer and/or speech. A number of today’s talks focused on freedom, in the context of access to data and code, and the freedom to use software (and hardware) the way you see fit. We actually had two great keynote talks on freedom, I’d like to step back to yesterday’s talk by Karen Sandler (you can see the talk for yourself on on youtube, which I’d highly recommended). Karen was diagnosed with hypertrophic cardiomyopathy, a heart condition that means she could suddenly die at any time. Thankfully there are treatments available, one of which is a pacemaker. Being the person she is, she immediately asked “what software does it run?”. Long story short, the manufacturer ended up…

LCA day 3 – High Availability

By | Technical | No Comments

Thursday was more of a “practical” day, with plenty of hands-on hacking. This is nothing new, but nowadays you’re more likely to talk about running a bittorrent client on your bluetooth headset than linux on your toaster. There’s some genuinely awesome, really cool hacks out there (Android and Arduino is where a lot of it’s at), but they’re unlikely to help us give you 99.8% uptime. 🙂 Instead, we’ll have a really quick rundown of the high availability (HA) and virtualisation talks, and why it’s a good thing we sent a sysadmin along to them. Complexity is your biggest enemy when trying to build reliable systems. Complex systems tend to be flaky, and that means they’re unpredictable. Unpredictable systems are bloody hard to support and rely upon. You won’t read…

LCA day 2

By | Technical | No Comments

Bit of a quiet day today, the highlight was probably the presentations on btrfs and xfs. Btrfs has been developing nicely, and Avi Miller got up to spruik some of the newer features of the filesystem. A bit like ZFS (which isn’t compatible with Linux licensing terms), it pulls in a lot of smarts that are usually the domain of your RAID controller/subsystem. This means more flexibility in how you handle your data, but a lot of new complexity too. It’s exciting stuff, but we’ll be waiting a bit longer to consider it robust enough to use in production. We’d kill for the integrated snapshotting (great for backups) and data integrity checking (store CRCs with your data) features. Meanwhile, XFS reports steady progress and positions itself as the filesystem of…

LCA update, Day 1

By | Technical | No Comments

Anchor’s talk went pretty well by all reports, huzzah! Actually, it wouldn’t be fair to say it was that easy, so I’ll let the cat out of the bag on this one: Panel 1 T-Rex: Our talk to linux.conf.au got accepted! Panel 2 {Close-up of T-Rex’s face, he is visibly excited} T-Rex: It will be AWESOME Panel 3 {Zoom out to show T-Rex and Dromiceiomimus. T-Rex is about to confidently stomp a tiny house} Dromiceiomimus: You’ve prepared the talk months in advance, right? T-Rex: 1337 speakers such as myself need no such preparation! Panel 4 {Utahraptor replaces Dromiceiomimus in shot, verbally catching T-Rex just as he is about to stomp a tiny woman} Utahraptor: But what about the slides? Panel 5 {Now some distance apart, T-Rex and Utahraptor look directly…

Anchor speaking at LCA2012, come listen!

By | Technical | No Comments

I think the title sums it up nicely. If you needed further incentive to come along, I would proudly inform you that my esteemed colleagues Messrs David Basden and Chris Collins will be discussing the finer points of the automated production of heterogeneous server systems. Activities will commence tomorrow (Tuesday) at half-past-ten in room C001, following the completion of elevenses. In all seriousness, we do hope you’ll come along if you’re attending Linuxconf and this tickles your fancy: Any monkey can build the same server over and over again reliably. But what if you need reliable server builds, and every single one is a little different? If you’d like a little more in-depth detail, the LCA website has a copy of the abstract for the talk. In addition to presenting,…
