Anyway when I put the DVD video in the drive in my Sony Vaio Laptop running Ubuntu Hardy all I got where I/O errors, some examples are below;

[ 2283.614887] end_request: I/O error, dev sr0, sector 418256
[ 2283.620351] end_request: I/O error, dev sr0, sector 418264
[ 2283.626273] end_request: I/O error, dev sr0, sector 418264
[ 2283.631766] end_request: I/O error, dev sr0, sector 418272
[ 2283.637013] end_request: I/O error, dev sr0, sector 418272
[ 2283.642384] end_request: I/O error, dev sr0, sector 418280

The Vaio’s DVD drive is connected via the USB bus. This is done so that drive can be completely powered down. The device turned out to be a MATSHITA DVD-RAM drive as shown via the dmesg output below;

[ 2909.596251] scsi11 : SCSI emulation for USB Mass Storage devices

It took me forever to figure out what was going on. I had seen similar problems on my desktop before when the disk was scratched but these where brand new disks. So I took the disks into work and tested it out on a friends Mac, it played perfectly. There happened to be a Steve Irwin DVD video disk lying around, so I popped it in the Vaio, it also played perfectly! What was going on?

After much searching I came across some reference to problems with region coding. It turns out that  MATSHITA drives won’t let you read a dvd unless they they have a region set. As I had never played a DVD video before the region on the drive had never been set.

There is a tool in Linux which can be used to do the region setting, it is helpfully called regionset. After setting the region to “Region 4″ I am now able to play my new DVDs! I wonder if I will be able to read my discs from the US and the UK. The libdvdcss2 should be able to decode the data if it can be read, hopefully the drive will still let that occurring. I will report back in comments here when I find out for sure.

It has been repetitively found that region encoding is anticompetitive and hence un-unenforceable in Australia. I have included a quote from the Stevens v Kabushiki Kaisha Sony Computer Entertainment case from 2005.

Ordinary principles of statutory construction, observed by this Court since its earliest days, have construed legislation, where there is doubt, to protect the fundamental rights of the individual. The right of the individual to enjoy lawfully acquired private property (a CD ROM game or a PlayStation console purchased in another region of the world or possibly to make a backup copy of the CD ROM) would ordinarily be a right inherent in Australian law upon the acquisition of such a chattel. This is a further reason why s 116A of the Copyright Act and the definition of TPM in s 10(1) of that Act should be read strictly. Doing so avoids an interpretation that would deprive the property owner of an incident of that person’s ordinary legal rights.

I thought I would just log my info here as there was very little information in Google about this problem. Hopefully I help some poor fool which brought a Sony Vaio like me.

Now I am back in Australia I have decided to trade in my Mac for a nice PC running Linux. People have continually told me that Macs are the epitome for polished UI and once you get use to them, there is no going back. When I suggested that this might not be the case, I was told “but you have never used Mac” - well now I have and I have specific examples of why Apple’s are less usable then Linux.

My first bone to pick is with the unlock screen. As I work at Google and might have the codes for the orbital space laser on my laptop, I need to lock my screen anytime I walk away from my desk. In gnome on Linux I can just walk back to my computer and start typing my password, it makes sure that all the keys end up in the password box - no so on a Mac. When I get back, I first have to move the mouse or hit a key, I then have to wait for the twirling multi-color ball and then I get to type my password. If I just start typing I loose the first 3 or more characters of the password.

Next is the useless wireless indicator that Mac has. On Linux I can clearly see if I am connected, trying to connect or waiting, I can also see if I am on wireless or wired network. This is all thanks to Network Manager which is very, very cool. On Mac, you can’t tell if you are connected or the Mac is having a shit and still trying to connect. Often, I had to bring up a ping program to see if the wireless bars meant I was actually connected or not. If I plug in the ethernet, without specifically disabling the Airport how do I know where my packets are going?

The twirling ball of doom. Normally programs either lock hard or work. Not on Mac, instead you get a ball which twirls forever. After waiting for 15 minutes I just hard reset my computer. At least if I knew the computer was locked up I wouldn’t have to wait that 15 minutes.

I have often gotten this error “You cannot move any item to the Trash because it is being emptied” when doing a secure empty of my trash bin. How hard is it to put things in the trash while emptying it?

Alt Tab doesn’t work. It doesn’t change between windows, only applications. Often I have multiple windows open in one application. I first have to “alt tab” to the correct application, then I have to “command tab” to the correct window. How annoying!

So that was just a few issues I have had. Overall, I am much happier with Ubuntu and it keeps getting even better.

I had given a similar talk at my local LUG only recently, I think that version went a little better but it was quite a different crowd. The first part of my talk came across way more preachy then I had hoped. I also see now how I can better use Thousand Parsec as examples of the tips I came up for releasing FOSS games. I guess practice makes perfect, maybe I’ll get it right to one day be able to give it at Linux.conf.au.

At the beginning this time I tried some of the “one word per slide quick succession” talk which Anthony Baxter had suggested. I think however think I ended up just insulting every American! I don’t think I speak fast enough to make this type of talk successful, but I’ll keep experimenting.

If you have any feedback on the talk, please do send me an email!

The real reason for this post is to upload the slides for the tech talk so they can be linked from the YouTube video.

Edit: The talk has now been uploaded, you can access it via the following link or see it below,

The week has been a little bit of a mess for a number of reasons. I’m joining the PSO group at Google which is only just started to establish a presence at the Sydney office, this has meant not a lot of people know what I should be doing. To make matters worse, I managed to arrive for the Memorial Day weekend (public holiday on Monday) which means the normal schedule for training (which starts on a Monday) is all changed. It’s still be very demanding and interesting anyway.

I arrived here in San Francisco on a Thursday (before I actually left according to wall time, Yay timezones!)  and after sleeping for about 18 hours straight managed to make it into the office on the Friday. The jet lag didn’t really end up hitting me until the weekend, so I’ve spent the last three days trying to reset my body clock instead of doing anything interesting.

I’m very pleased with the transparency inside of Google. I have yet to find a door which my keycard won’t open or a website which I can not access with my login. Of course I can’t tell anyone outside of Google what I have found out which is annoying, there is a lot of cool stuff going on.

Having worked mainly for small companies in the past, it’s nice to be able to walk into TechStop (Google’s tech support department) and get both hardware and support. It’s nice having small things like beverages (such as that all important coffee) and food provided. The food in the Sydney office is not bad, but it pales in comparison to the variety and quality that you get here at the Googleplex.

I have heard that people worry that with all the food at Google you just end up going to lunch with your work mates, I don’t think that is something having food provided creates. At the my previous work I ended up in that situation, always having lunch with the same people at the same locations, the only difference is that I was paying for it! Google is liberal about letting you invite friends to have lunch at their free cafeteria’s too.

Over all, it has been a very busy and interesting week. I’m looking forward to what tomorrow (and the rest of this week) holds.

Linux rocks, FreeBSD rocks - but Linux and FreeBSD rock.

Which is correct use of rock verse rocks but I have no idea why. Suck also works like this,

Windows sucks, MacOS X sucks - but Windows and MacOS X suck.

This just proves that I know nothing about this language I use every day. Could a linguist please explain this?

I’m very excited too start working with Google but it has been pretty big decision to make. I have never moved anywhere permanently before and I’m currently still living at home with my parents. I did live in Sweden for 6 months, but that was always with the intention of coming back home. On the other hand, it is not like I am moving to totally a different country and I already have loads of friends and family living in Sydney.

I have been thinking that I want to move to a big city for a number of reasons. An example of this that I often use, is that “I want to be able to order pizza after midnight”. It is annoying that just when I’ve started getting more involved in the local FOSS groups I’m leaving for another state. I do hope to continually be involved with SLUG and other FOSS events going on in Sydney too.

I’ve spent most of this ANZAC Day long weekend trying to organize all my stuff. You never realize how much crap you have until you decide to move and I don’t even own any furniture yet! Luckily my parents have plenty of storage space. Having never done this before, I’m sure that I’m probably doing it all wrong.

I’m a little bit of a technology pack rat (like most geeks) but I have been trying to give away all the old computer bits that I had always being meaning to fix or use. There should be plenty of happy Adelaide FOSS people soon

If you are in Adelaide and want to catch up before I head off (Friday the 16th), or in Sydney (or even the Mountain View, USA) and want to come and say “Hi!” please feel free to email me.

For thoses who don’t know, Epiphany is generally described as “the closest thing to Gnome’s official web browser”. It has lots of nifty features and use to have much better intergration with the Gnome desktop (things like actually using the Gnome print dialog). I use to advocate that Gnome should push Epiphany instead of Firefox.

So why have I given up? I’m tired of my browser being broken.

The developers of Epiphany decided to make some huge changes in the latest version, they started adding support for the WebKit (the render behind Safari) instead of just being dependent on Gecko (the same render Firefox uses). This is actually a very good goal, being able to have a choice of renders in my browser would be great. However, in the process of doing this change they broke everything! Things like the vitally important Adblock extension no longer work and the password manager is totally broken in a number of ways - for a long time they didn’t even show up in the dialog.

I’m okay with a few bugs here and there (even these quite serious ones) to get something better in the long run. I have diligently reported bugs as I found them (even firing up a different browser when the gnome bug browser was crashing Epiphany). I even started porting Google Gears to Epiphany because I had faith that Epiphany was going to remain a killer browser.

Now I find out that it has all been for nothing, the developers have decided they are going to totally ditch Gecko and move only to WebKit (with all the compatibility problems it will bring). There are so many reasons why this is a bad idea, none of which I’m going to repeat here.

So I’m now writing this in Firefox instead of Epiphany and I’m pretty happy. Having access to all the extensions that Firefox has is really nice for once. There a number of features which I miss from Epiphany and extensions have filled most of that void, so what did I install?

• Tab History, this means that new tabs have the same history as the parent tab. This is something Epiphany does by default and I find absolutely vital.
• Compact Menu 2, a little extension which gives you the ability to have all your menus in a single button saving you precious vertical screen space.
• Ad Block Plus, got to keep away those evil ads. It’s amazing how annoying the web is with ads, I had gotten so use to not seeing them that I didn’t know how bad it actually was.
• NoScript, get rid of all that annoying flash and evil javascript. In epiphany I generally ended up just apt-get removing flash, now I can still watch stupid Youtube videos without being violated by monkies.

I also installed two extensions that have no equivalent under Epiphany, they are

• Greasemonkey, the extension for making websites the way you like them.
• Firebug, a really cool tool for figuring out how a website is made up and various problems with them.

I’m still looking for an extension which makes the Firefox 3.0 URL bar sane. I really like how the Epiphany one behaves and will probably end up writing my own extension if I don’t find anything. The important features that I require are,

• Single line per URL with the title on the right.
• Support for “smart bookmarks” as the last option. These let you search for the current term at Google or Wikipedia without prefixing it with a stupid keyword or something.

Here is what my Firefox looks like currently. As you can see I have significantly customized the toolbar to remove all that excesses.

Google has just published the list of accepted mentoring organizations for Google Summer of Code 2008 and it is great to see that Thousand Parsec has made it once again. We must be doing something right

So, if you are into turn-based 4X space strategy games and would like to help in game development, this is your chance. Take a look at our Google Summer of Code and Ideas for Programmers pages and get involved. There is even US$ 4500 to encourage you to take that step into the world of open source software programming.

Interested students now have about a week to get to know us better. You can chat with us on IRC (Freenode network, #tp channel) or write to our development mailing list. Starting March 24 student applications can be submitted, all applications must be in by March 31. I’m looking forward to be a mentor again.

The day on a whole was fairly successfully and there where lots of interesting talks, panels and tutorials. One of the coolest talks was Douglas Bagnall’s “Playing with Crayons“, while we had a number of technical difficulties with getting his laptop talking to the projector (he has an evil Nvidia card), it was really cool to learn about this program which turns a kid’s crayon drawing into a playable game. Douglas has now open sourced the code and looking to port it to the OLPC!

We also had some very cool panels sessions. The first was about using FOSS in Game Development education, we had some representatives from some of the top game education institutes in Australia. The second was an interesting licensing panel which includes Jessica Coats from Creative Commons Australia and Kimberly Weatherall - a former Rusty Wrench winner. I think our last panel was the best however, people got to grill representatives of the Australian commercial game industry on how they are using FOSS at their commercial game companies!

There where also some really good talks by Richard and Alex about pyglet, including the most impressive live coding I have ever seen. As the pyglet tutorial is so cool and I have also uploaded it to Google Video for your viewing pleasure. Of course, we couldn’t keep Rusty Russell away, he gave a short lightening talk about his new Pong Hero!

So why not download the Gaming Miniconf vidoes and take a look.
