I notice that Russell Coker has boarded his Soap Box on the topic of Small Form Factor laptops for Schools. In it, he says

There is no information on what OS is installed on the Intel Classmate. I’m guessing that it’s some proprietary OS (I expect that they would boast if they were using the higher quality open source software).

Yet, when I visit the classmate website,  I can easily Navigate to a page that lists the Operating Systems ( Classmate PC -> System Configuration -> Software) which clearly list Mandriva Discovery as one of the Operating Systems. Not sure why Russell couldn’t be bothered to get the facts for his arguement, but sometimes it’s easier to argue without checking the points.

For those of you who wanted to be at LCA, and couldn’t

The Mel8 Technical team, along with the Real Time Communications Section of AARNET, The bandwidth sponsor for Linux.Conf.Au 2008, have organised a special treat for you.

If you really want to be at the Keynote tomorrow, but are stuck at work earning a crust, at home watching the kids, or in a cafe enjoying a coffee, you can tune your VLC compatible player into http://ogg.aarnet.edu.au:8000/lca.ogg and watch the action live from 9am

That’s right, even though we’ve sold out, as a special treat to everyone who wanted to make it and couldn’t, we’ve organized to have the Wednesday Morning keynote available via a VLC compatible stream.

Enjoy!

Spent today catching up on bits and pieces that needed to be done before we headed back up to Gosford for the funeral. One of those was catching up with mail that came in while we away. As I mentioned yesterday, there was some Registered post items that needed to be collected from the LPO.

One of them turned out to be from our Estate Agent. We’ve been expecting copies of our lease renewal we recently signed, so this wasn’t totally unexpected. What was unexpected was the letter that came instead, which turned out to be a very official looking form letter informing us we have now formally been provided with 60 days written notice, and must vacate the premises by the 26th of February.

They say bad news comes in three’s, so I’m loathe to think what the third one will be.

christmas was cancelled

December 27, 2007 – 4:42 pm

Things have been a bit rough here at casa de Walsh for the last few weeks. In early October my mother rang me to let me know that she’d been in hospital for tests, and that there were some lumps on the liver and the left lung that had her specialist a bit worried. I managed to swing a work trip to Canberra in October that allowed us to continue up and spend some time with her.

In November, she rang to let me know they had determined the liver was the primary tumor, and the growth on the lung was a metastized tumor. I tried to speak to her at least once a week, but the times she was in hospital and allowed calls often occurred at times when I was not able to be near a phone. In mid December I was able to swing another work trip, this time to Sydney, so I flew up early and got to spend another day with her.

Last week we got a call from my Sister to say Mum had requested she be admitted to a palliative care home, so we packed a bag and headed up for some more time with her. First asshat award goes to Qantas, who canceled our flight, and in attempting to rebook us on another flight managed to completely delete our original booking, which then resulted in them needing to generate a credit note, then apply the credit note to a booking, which meant that our 5.15pm flight became a 8.30pm flight. Add to that the train to Gosford and we got to my mother’s house around midnight.

We got to spend some time with her over the next few days, but it was obvious that each time we saw her she was getting weaker and weaker, and eventually by monday communication was primarily by us asking closed questions (i.e. yes/no answers) and basic sign language. Due to a number of reasons, we had to come back on Monday afternoon, so we flew back and got home around 5pm. Spoke to the neighbours, collected the mail which included some registered post cards, and opened the house up. Just after 8pm we got a phone call from my brother letting me know Mum had passed away in her sleep. Scratch Christmas for another year.

and the winner is…

I managed to snarf the ISO’s the day before yesterday when the internode mirror admin fell asleep at the switch, but for the general public, Fedora8, codenamed “werewolf” has been released.

I’ll post a quick review hopefully over the weekend, but for now, the CD artwork says it all;

The Wolf

I’ve managed to acheive one of my targets for this year, and the results are here

From here, it’s onto the CSS stream of training.

And within 2 hours of updating my linkedin profile, I got a job offer.

Free != loved

September 13, 2007 – 11:02 pm

A few years, A friend who ran an ISP and I decided to launch a public access wireless network. Nothing excessive, no masts or dishes or custom rolled kernels for a WRT sealed in a box. Just a few DSL links in Cafes and Restaurants for people who might need a bit of net with their coffee. No charge, no “key this code into a captive portal for 15 minutes of internet”. Open your laptop, associate to the network, do stuff. Of course, as you can probably guess, people loved it at the time. I got a few feedback entries from the “l33t h4ck3rs” telling me they’d hacked my wireless network and there was nothing I could do to stop them from doing it again, but things were generally good.

At one point we had upwards of 10 sites going, but over time it’s dwindled back to 2, mainly as business change hands and the new owners don’t see the benefit of having a wireless network “just anyone” can use, and want to restrict the access to people who have bought a large part of the menu. I had access to the LNS (radius for ISP) side of the network, so I could see what sites were connected, and what ones weren’t, when they were last seen, etc, which allowed me to do some proactive work in regards to keeping the host sites happy and feeling like a provider actually cared about them.

Unfortunately, my friend wound up his ISP earlier in the year for a number of reasons, and sold his client base to a few ISP’s. The new ISP that bought up the links I was using obviously didn’t want to give me access to their LNS, so when the two remaining sites have problems, I need to ring their support line,wait around, talk to someone, be escalated, put on hold, etc. A job that took 30 seconds, now takes nearly 30 minutes. But, they were perfectly happy to charge me the same amount of money as my friend was. I eventually got tired of this as one site experienced several drops out a day, so I decided to churn their connection to another ISP I’ve been working with. We negotiated a timeframe that suited the restaurant, I sent emails out to the groups that I know use the internet connection when they meet at the restaurant, and the churn got submitted.

For what ever reason (and as always happens when Telstra is involved in anything), there was a problem with the churn that was scheduled for today, and the line is currently in a locked state. Sure enough, at 7:00:01pm tonight, I get an upset phonecall from the convenor of one of the groups asking if I can “hurry the churn along”, as they are meeting there and wanting to use the Free wireless. The fact that I haven’t heard a peep out of any of the groups that use it when it is working, and get nothing but grief when I attempt to improve the service makes me wonder if it’s worth it, and highlights (to me) one of the larger problems with Free software;

Everyone loves you when it works. When it doesn’t work, you better not show your face round these parts.

relaxing while stressing

July 12, 2007 – 10:21 am

It’s that time of year again, and the annual Queensland Science and Technology Network (the QRNO of aarnet) conference has rolled around again. This year it’s being held at the Cairns International Hotel, hosted by James Cook Uni. I flew up on Monday, and it’s been a great few days so far, getting a chance to catch up with people from aarnet, the CARNO crowd I spent some time with while I was in Canberra, as well as finally meeting some people that had up until now been voices on the other of the phone.

I’ve also come across some great ideas and projects other people are doing that I can leverage for my current contract. It’s also been good to catch up with the aarnet middleware and application framework people like James Sankar, as well as the John Stevens from Deakin. I’m working with both John and James on the Eduroam Steering Committee, which I was invited to join earlier in the year following my work on the project last year.
I really love coming to research orientated conferences like questnet, mainly because you get to talk to people that are not only passionate about their work(like foss people), but you get a glimpse of the stuff that’s going to be coming into education/research main stream, and it really makes you realize that maybe the higher education sector may not be as screwed as people make it out to be. Speaking to people from CSIRO who can max a 1Gb fibre link without trying, (and that’s after throwing away 80% of their data set), or others who are now looking at bringing sensor arrays on line that do native 10GbE feeds for Radio Telescopes and astronomy.

After discussion with my contract supervisor, I put a paper in on the rather broad area of Disaster Recovery, and much to my surprise it was accepted. Apparently this year they had way more submissions than slots, and they were still deciding the papers in early June. I was part of the final group, and ended up being on of 15 people considered for 12 slots. After I got notice, I started Bouncing the idea around for a while, and decided that rather than cover all the stuff that’s been hashed to death like dark fibre and off site recovery centres, I’d wind it back to look at 4 things; Multi-homed BGP, Anycast DNS, Failover-DHCP and HA heartbeat.

Whilst the last isn’t really disaster recovery related, a lot of the DR plans I’ve seen wait for the system to completely fail before attempting restoration of service, so there’s already the pressure there when you lose your boxen. Kim Hawtin planted the seed for the Anycast DNS and Failover DHCP with his talk at LCA07, and was more than happy to answer my questions as I prepared the presentation. The Multihomed BGP is always something I’ve been interested in for my own pops, but haven’t really had the need or money to bring up.

My talk is first up tomorrow after the Plenary sessions, and should on the codian IP-VCR by lunchtime. Poke me on IRC if you’d like a link to it and I’ll pass it on.
