IPv6Summit Organizers
IPv6 Summit Summary link
Posted on 2011-05-14.

I'm late with this update (busy catching up on other work that I neglected last month) but I must report that the Ottawa IPv6 Summit went far better than I had hoped: Great turn-out, great venue, great talks and great food.

Pictures are now available from Richard Guy Briggs and we're working on putting the talk videos online with the help of ISI Global Webcasting.

The space at Telfer School of Management was ideal, and the Telfer volunteers got everyone registered helped everything run really smoothly all day.

It was tons of work, but I look forward to doing it again. Maybe I'll even catch more than a couple talks in person next time.

Ottawa IPv6 Summit Overflow link
Posted on 2011-04-27.

Response to the Ottawa IPv6 Summit has been amazing. Yesterday we completely sold out our venue and had to shut down registrations. We just can't fit any more people in the room with the keynote talk first thing in the morning.

We do still have some room after the keynote though, and if you don't mind skipping the first talk you can now register for one of the overflow spots we have just made available.

Hope to see you on Friday.

Registration for the Ottawa IPv6 Summit has just opened. Also if you want to present a talk (in particular something suitable for the business/management stream) there is still some time to submit a proposal.

The summit will be held Friday April 29 in downtown Ottawa at the new Desmarais building in the University of Ottawa campus. There will be some great talks, a good lunch, fast wireless, power at every seat and plenty of interesting people. I'll post again when the schedule is available.

The conference is being organized by a small group of volunteers, including myself. If your company is willing to sponsor the event please contact the Ottawa IPv6 Summit. The money will go directly into making the conference better for everyone attending.

Posted on 2010-11-29.

Many hard drives available today have 4K physical sectors instead of the old standard 512-byte sectors. The larger sectors allow the manufacturers to save space required for error correction, so they can save money, and in turn we get cheaper hard drives. Which is great, except that if a drive is using 4K sectors the drive must report it to the operating system or performance may suffer.

I recently purchased two WD HDDs: one 1.5TB and one 2TB, both "EARS" models. The 1.5TB drive happily reports that it has 4K physical sectors:

fdisk -l /dev/sdc
Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes
...
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

But the 2TB drive claimed to have 512 byte sectors.

fdisk -l /dev/sdd
Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes
...
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

"That's strange", I thought. So I ran a quick test to see if the 2TB drive was lying.

Ubuntu NBR on an EEE 900
Posted on 2009-01-26.

I picked up an Asus EEE PC 900 a couple months ago, and it quickly became the most heavily used computer in my household. I have been running the included Xandros Linux OS and Firefox, Thunderbird, Skype (Beta for video conferencing) and Picasa (Linux Beta). Xandros makes a nice OS, and the EEE works very well in its default configuration. My only complaint is it that seems Xandros has abandoned the OS in favour of versions for the latest EEE models: there are few additional packages to install and fewer updates to the packages that are available.

The EEE community site has recommendations for adding external repositories, but that doesn't seem like a sustainable choice, with the steadily aging base Xandros packages. One of the biggest strength of Linux distributions is the constant improvements available and new software available from all over the world, something Xandros just wasn't going to provide. I use Ubuntu primarily on my other machines, so I gave Ubuntu Netbook Remix (NBR) a try.
