Mikey's Blog

Let's pop down to Zurich next weekend

OK, that's a pretty wanky title, but it's what Jo and I can do for the next few months while living Tubingen, Germany.

The story goes like this... about 6 months ago Arnd Bergmann suggested doing an exchange with him after LCA 2008. After thinking about it for all of about half a second, Jo and I decided to take him up on the offer. So we are spending 2 months in Tubingen, then a month traveling around Europe, then another month in Austin, all while Arnd lives in our apartment in Canberra.

We arrived in Germany about two days ago and got settled pretty quickly. We met our lovely new house mates, Ines and Sebastian, did a quick tour of Tubingen and then headed into the Boblingen offices where I'll be working.

I've setup a photo gallery here and thankfully Jo has started a blog, so you won't have to put up with me murdering the English language, just to find out what we are up to.

Source Control Rulage/Suckage Ratio

It's time to bring some real science into the source control debate. Google Rulage/Suckage ratio!

Howard Politics

Kristy, I completely agree that something needs to be done to stop the abuse of children. My point was about politics and process, not the policy itself.

What I do object to is the way in which Mr Howard is using this issue for political purposes. If he really considers this a national emergency, relevant leaders would have been consulted - or at least notified - of the policy prior to any announcement. Instead, Mr Howard attempted to get agreement from leaders while they learnt of his plan under media scrutiny. Doing this serves only one purpose, to paint him as a strong leader and put other leaders on the back foot. That is not about helping the children, its about winning an election.

In response to a couple of criticisms:

After 'children overboard' and locking kids up in detention centres for years, I don't think its wise to *trust* that Mr Howard's policy will be implemented in a way that is far better than how it initially sounds.

Yes, as a society we pay for child abuse. We also pay for racism, governmental overreaching and political manipulation.

Questions that this policy could cause long term damage for indigneous Australians, and possibly perpetuate the abuse of children, deserve decent answers - not spin.

Also, just how regularly do need to blog to avoid having to show taste and insight? :-P

Howard on message.... I mean, Howard on Indigenous Child Abuse

Interviewer: So isn't your new initiative over reaching?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: OK.  So is it possible that your new laws are 
             unconstitutional?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: Isn't it possible that you'll alienate Aboriginal
             communities?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: Is it possible that this will cause long term
             damage to these communities?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: Aren't you just overriding the States and Territories?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: Aren't your new laws racist by imposing
             restrictions only to Indigenous Communities?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: What evidence do you have that shows prohibiting
             alcohol and pornography will prevent child abuse?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: OK.  So what about the children you locked up in
             detention centers?
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: So is it true they've been throwing their children
             overboard?	
Howard: Well possibly, but won't someone think of the children?!?

Interviewer: Doesn't this enable you to escape any legitimate
             criticism of your policy by using political spin to claim
             this is only about the children?
Howard: Well possibly, but won't someone think of the children?!?

Jo and I spend the last 4 weeks traveling through Singapore, Spain (Seville, Granada, Valencia and Barcelona) and Sweden (Stockholm, Kiruna, Lulea, Hoga Kusten and Lake Siljan). Load of pictures here.

Bitfield

I've been helping jk with the simple but wonderful bitfield (me helping mostly equated to telling him what features I wanted, followed by him telling me he'd already implemented them and then laughing at me).

We now have bash completion, vim modes and Debian/Ubuntu packages which can be grabbed from here:

deb http://neuling.org/devel/bitfield/ ./

We are looking to improved the register database, so if you have any register definitions you'd like added, email jk or even better, grab the Mecurial tree and submit it as a patch.

Telstra's Next G

Being the geek I am, I was interested in finding out what the hell this Next G stuff from Telstra was all about. So I search and find http://www.nextg.com.au.

Looks like a pretty simple page, with one obvious link to:

ENTER STANDARD NEXT G EXPERIENCE

Ok, sounds good hopefully there'll be something in there...

To find out how Next G will benefit you, just answer a few simple questions (between 1 and 5). Hit the 'NEXT' button to proceed.

Bad sign, but let's persist... It's only 5 questions after all.

Question 1.

What best describes your needs today?

[ ] Personal

[ ] 55-59

[ ] 60+

Humm, kinda wierd but ok. I click 30-34.

Question 3.

Please insert your postcode [ ]

Arrh, definitely useful technical information so they can work out coverage. Maybe this isn't going to be too bad

Question 4.

Which best describes you?

[ ] My friends' opinions are important to me

[ ] My main aim in life is to be a good parent and provide for my family

[ ] Both

[ ] Neither

Err... what the fuck?!?! I just want wireless broadband! I close my eyes, think of home and click Neither.

Err ok.. so this is question 6 of 5.. interesting, very interesting.

So, Rusty suggested it's time to run the Telstra Next G Stupid Question competition. Email me your suggestions for the questions Telstra should have asked, and I'll post them online. eg:

You are standing in a watch tower and Dubbya enters your gun sight. Do you:

[ ] Take out the Leader Of The Free World

[ ] Buy T3 shares

[ ] Buy T3 shares

[ ] All of the above

Puzzle time..

I've not done a puzzle for a while and I heard this the other day. Apparently a common Google job interview question.

You have 8 balls, all of which are identical expect 1 slightly lighter than the other 7. You also have a balancing scales. Using the scales only twice, determine which of the 8 balls is the light one.

Email me if you have a solution/question. I'll post the solution in about a week.

Update: I got lots of responses to this puzzle. The solution is (I stole the best worded response, thanks Ian):

Keep two balls aside. Weigh three each in the scales. If the scales balance, it's one of the two spares. Balance them, and pick the lighter one. If the scales don't balance, compare two of the three balls from the lighter side. If those balance, it's the third ball.

This is fun, but a big time sink...

Google Image Labeler. Cool idea. Reasonably simple and accurate way to categorize images. I wonder if they'll release the collected results for others to use as training data.

Canberra mountains

After MPE's recent post, I decided to put together altitude profiles for the various mountains around Canberra that I've ridden up. They are normalized to 0m at the start. Black Mountain is the greatest altitude difference and the steepest. Red Hill is almost as steep as Black Mountain but much shorter. Stromlo is the longest but shallowest.

Updated: Added Mt Ainslie.

After months of work by a large and diligent fact collecting team, we finally have AntonBlanchardFacts.com! All items have been triple checked for accuracy.

Quickies...

Jo and I headed to Adelaide for Kristy and Paul's Wedding. It was a really nice civil service held in the Adelaide hills at the Chain of Ponds winery. I've put some photos up here.

I've went up to Sydney to do a short 2 day training course. I managed to catch up with MBP and Steph who are now living in St Lennerds in North Sydney. Steph suggested that we went to RedOak for dinner which was excellent. Highly recommended.

Along with Anton, I spent the majority of May in Austin working with our team over there. I managed to catch up with most of the crew over there. Todd took us out water skiing a couple of times on Lake Travis. Went to a Mr Sinus Show at the Alamo Draft house downtown where they serve you beer and food while commentating B-rate movies. Also went to a live music show at Antone's with BCG. Overall a good and thoroughly productive trip, although it's great to be home again.

Cotter Uriarra

Grubby and I did the Cotter-Uriarra loop on Saturday. Really nice ride. Not many cars around, even being a mid morning/lunch on Saturday. Not as hard as I though, but still lots of climbing, especially out of Uriarra coming back to Canberra. We also did a quick run up Stromlo after for good measure.

I've added a total altitude loss and gain summary to my GPS page. The complete ride yesterday was over 1000m of loss and gain. The Cotter/Uriarra loop is around 600m loss and gain.

Jo's work

Jo just scored a new job with Prime Minister and Cabinet in the Social Policy Division. She'll be working in the health group as their PBS expert. Should be fun. The hours will be longer than before but fortunately they are only 5 min walk from my work.

Quickies

Some snippets from the land of neuling.org:

Dunedin was fun. There are some photos here.
One particular night, we went out to a bar to grab some beers (this was regular (read: every night) occurance during the conf). We ended up standing outside but then a bouncer came up and said we had to have a seat if were to remain outside. So, while we were gathering out thoughts, the bouncer also said "Hey, are you guys at that Linux conference?".
"Yeeeaah?" we replied.
"Well, I'm studying and I use Debian all the time!" he said back, much to our amusement. We talking to the bouncer for a while longer as we started to head inside.
Then over came another bouncer who was a huge scary looking guy. He comes up and says "Hey, I'm a Debian user too!". Hence we now have The Depricator! (see picture)

The current Liberal government is nuts!

Some CControl stuff happening. I have a Mercurial repo here, if you want to try my additions and merges with other people. I'm starting to get into Mercurial which is great for a distributed project like this.

That's pretty much it for now. For all the stuff I've missed, checkout Bruce's boyfriend's blog.

It begins...

The Ugly Stick

Despite having 3 (yes 3 people!) separate blogs, Simmo is quite a smart guy. In a recent post, he mentioned The Ugly Stick which is a new show on community TV. So trusting Simmo I downloaded[1] the first 2 episodes. It's pretty silly stuff and plays a lot on our lazy Australian culture (I'd be surprised if people from another country enjoyed it). Anyway, check it out.

1. which is a great concept for artists trying to get their stuff out. As Rusty says, obscurity is the greatest threat to vast majority of artists, not piracy.

Quickies

No updates for a while, so here's some snippets:

Jo and I headed back to Adelaide for Christmas and New Year. We had a great but tiring time catching up with lots of friends and family. Thanks to those who made the effort to see us, it really means a lot.

While back, we went flying a couple of times with Dad in his new plane. First trip we went for a longer flight over Goolwa and Strath. Afterwards I fixed Dad's GPS which didn't have a power adapter for the plane and was chewing through batteries. After heading down to Jarcar for some components, I made up a small circuit board to regulate the plane supply voltage down to what's required for the GPS. After looking at the plane's electrical schematics, we decided where to splice into the supply, pulled out the trusty soldering iron (trusty being that it was purchased 5 min before hand at Jaycar) and soldered it into the plane. Much to my amazement, it all worked.

For the second flight, Jo went up with Dad and I went up with Larry (another "fly boy"). We ended up flying around only 100m away from each other, which was a very cool experience. There are some photos and videos of this flight here.

Congratulations to Brad and Tennille who are expecting their first child in August. Congratulations again to Brad for winning the University medal for best PhD at Adelaide Uni in 2005.

Seeing Machines IPOed. You can watch all the fun here.

I'm off to LCA in Dunedin, New Zealand next week. I'm then back in Canberra for a busy week with Duncan and Alex staying with us and loads of post LCA work functions.

CControl Debain

CControl has been Debianised. I'm hosting an apt repository at neuling.org. If you want to use it, add the following line to you sources.list (x86 only at this stage):

deb http://neuling.org/ccontrol/ ./

You'll then need to run ccontrol-init to create a default configuration file and then add /usr/lib/ccontrol to the start of your PATH to pick up the new gcc, cc, ld, make etc. (eg. export PATH=/usr/lib/ccontrol:$PATH)

Why use ccontrol..

ccontrol is great! Here are some reasons why (in dot points, 'coz everything is better in dot points!):

It's very easy to setup. It even does auto probing of your network to find distcc hosts.

You can use it to compile any package without the need to screw around with Makefiles etc. Just type make everywhere you want to compile

It's been tuned it so that interactive performance on your local machine is not compromised during compiles.
Examples:

I used crosstool to install the 64 POWERPC GCC cross compiler on my x86 laptop. I didn't need to do anything special to get it to work under ccontrol, just downloaded crosstool and build as usual.

I can now build 64bit POWER Linux kernel on my laptop without playing with Makefiles or even having to specify any parameters to make (even ARCH=). This also uses distcc as you'd want. ccontrol works out what you want based on the directory name.

In the tradition that Michael started... What is this image?

In this country, you gotta make the money first. Then when you get the money, you get the power. Then when you get the power, then you get the ccontrol releases named after you.

I've been playing around with xplanet markers and the Real Time Cloud Map and to create a background that updates with timezones, weather and the movement of the Sun/Earth. I'm updating the background on my laptop every 10 min. The source markers file I create looks like this:

-35.294,149.113,Canberra,Australia/Canberra
30.261,-97.745,Austin,America/Chicago
51.502659,-0.279680,London,Europe/London
1.43,103.81,Singapore,Asia/Singapore

These get translated into xplanet markers containing the actual time in each location. I then run xplanet passing it the latest clouds image and markers file to produce the final result. A sample image is shown here.

Last night I was getting my hair cut and my usual hair dresser said "I have some bad news, this will probably be the last time I cut your hair as my boyfriend got a job in Brisbane and I'm moving there with him".
To which I responded "Sorry to hear that. I guess being a hair dresser means that you easily find another job up there".
To which she responded "Yeah, true... and you know, the world is only getting more superficial, so there's always going to be plenty of work around for me".
I'm use to getting this type of argument from my left wing hippy friends, but not my hairdresser!?!? I'm definitely going to miss her.

I bought myself an IOGear GME225B Bluetooth mouse. Works nicely under Ubuntu Linux (Breezy) with a simple

sudo hidd --connect XX:XX:XX:XX:XX:XX

command while holding down the connect button on the bottom. I didn't even have to restart X. It recharges over USB and can still be used while being charged. My laptop has Bluetooth built in, so it's a very neat solution requiring no cables or dongles (except when charging).

Michael, Anton and I headed up to Andrea's folks place for Thanksgiving day. Thanksgiving is notoriously bad for traffic but we managed to make the 180miles to Dallas in 3 hours with almost no traffic issues.
Our Thanksgiving meal was much like my usual Christmas dinner in Australia. A sit down meal with loads of turkey and ham with a number of side dishes. We also got stuck into the wine with quite a few bottles emptied.
After dinner, Andrea and Nancy took us down to the GayLoad Texan (sorry Simmo, I couldn't get you a T-shirt) to have a few drinks and look around. Pretty amazing building.
We stayed the night in Andrea and Nancy's huge new trailer/caravan, then headed home. Fortunately, the traffic on the way home was also pretty light.
Many thanks to Andrea and Nancy, and to Andrea's family for looking after us so very well.
Anyway, enough with me rambling on, here's some photos.
Update: Michael's take on events.

I've seen a couple of good bumper stickers while in Texas.
One was a picture of a "W" in a circle which was crossed out. Next to it said "Wake me up when it's over"
The second one was "Unions: from the folks that bought you weekends"

I'm in Austin Texas currently for work. I realised I'm a bit more spoilt these days when I found myself complaining that make -j4 is not enough grunt.

More evidence little Johnny is more interested in terrorist sensationalism rather than actually protecting us:
"There were 10 changes to the Crimes Act since June last year, since surveillance first began on these folk, and any of these 10 changes would have allowed this alteration of the word 'the' to 'a' or 'a' to 'the'."

I normally watch the SBS news as IMHO it's far better than the commercial channels. Last night confirmed the shitty state of commercial news when one of them had a segment on a new drug to prevent migraines. It really shits me when they present something as news when it's obviously an ad for the drug company. Added to which, drug ads are not allowed in Australia. Immoral and quite possibly illegal activity.

I've not blogged for a while so here's some quickies,

Mum and Dad visited a couple of weekends ago. Good food and conversation as usual.
Work is busy and sometimes overwhelming. Lots of things to learn. Hopefully I can contribute when I can cram it all in my head.
Saw the Chaser guys stage show the other night. I wouldn't bother again.
Heading to the US in a few weeks but will be back before Christmas. Unfortunately, will be apart from Jo for the whole trip.
Apple launched a iTunes Oz site. Rusty/Chris mentioned that they do the DRM on the client so if you use the Linux tools, there's no DRM.
I got a new hair cut (new style after god know how long)
Canberra is extremely green ATM. The most green I've ever seen it.
I have a last.fm account here so you can see what I'm listening too (note to self, get more music on laptop).
Try the Australian politics test and let me know the results.
Planning to catch up with Duncan who is here this weekend.
I've been catching the "Loser Cruiser" to work about once a week.
Been riding my bike about 3 times a week as well. Been going via Red Hill to improve my climbing a bit (short but very steep).

Tridge grabbed my google maps based GPS stuff and has improved it greatly adding a lot more client side java script. He's setup a bzr repository for the code at http://gps.ozlabs.org/ (google API key is for gps.ozlabs.org only).
Anyway, I found a line drawing package for java script so I've added some graphing abilities to his stuff. My first play with java script and bzr. You can pull from my tree at http://gps.ozlabs.org/mikey/. I've also setup a test page for my stuff here.

Friday, October 07, 2005

I've done the wanky thing and registered my own domain at neuling.org. From now on I'll be using mikey at neuling dot org (please delete any other addresses). I'll start moving other stuff over there (photo site, this blog, GPS page etc) when I get time.

Jo and I spent the weekend in Brisbane with Di and Brad. We had a fantastic time, mostly just hanging out in the city with them and their friends. Highlights included, the night cruise up the Brisbane river past the CBD on the CityCat and the closing night at Sur Taj. Thanks for a great time guys!!!! Some photos are available here.

Big weekend. The Taken played the Pot Belly Friday night. The other 2 bands were pretty good as well, the last being a rock'n covers band which played, amongst others, KISS and couple of Billy Idol song. Stayed out pretty late with some of the OzLabs guys causing Saturday to be a bit of a waste. Saturday night we saw Diesel at Tilley's. The show was similar to last time with just him and an acoustic guitar. Unfortunately there were some feedback problems which were rather irritating, but other than that, he's a brilliant performer. Sunday I went on the inaugural CLUG Bike SIG. Ended up riding a total of 67Km from leaving home to getting back with my first go up Black Mountain which is the hardest mountain I've climbed so far. Did it in a reasonable time for a first attempt, although Steve, who joined me, kicked my ass.

I've been playing with the Google maps API and GPSBabel. GPSBabel has beta support for my GPS under Linux and after looking at some packet dumps for a while, I managed to work out how it my GPS split tracks for each run and submitted a crappy 2 line patch. After a little scripting, I can now download runs and upload them to my site automatically. Checkout Mikey GPS runs.

Riding home tonight around State Circle, someone in an SUV coming out of a side street didn't see me, ended up locking up his brakes and, fortunately, stopped just beside me. He didn't come too close to hitting me and I did see him coming, so overall it wasn't too bad an incident.
Anyway, after letting me past, he pulled up next to me and wound down his window. Thinking I was about to get a blast of "Get off the road you stupid hippy!" I was very surprised when he apologised saying "Sorry about that, I did see you through that pole". Although a pretty lame excuse (if you can't see, don't assume you can go), I'm impressed a bicycle rider got an apology from an SUV driver.

Two features I really missed from my GPS was pedal cadence and following prerecorded courses. Garmin have just released a GPS Cyclocomputer which supports these, plus all the other stuff mine already has. I really love and hate how fast technology moves sometimes, not that either of these features are especially new.

Tuesday, August 30, 2005

After Steve's ride up stomolo the other day I thought I'd try it out. I did it the other day in 13:36 (ave 15.9Kph over 3.61Km) but after talking to Steven offline, I realised I was about 300m short of where he measured from and to.
So I tried again and this time put in a more effort. I managed to do the climb in 13.14 (ave 17.8Kph over 3.92km) which I was pretty happy with (over all ride was ave 27.1Kph over 29.64km). I managed to keep my heart rate at an average of 185bpm over the climb and 168bpm over the whole ride. Even on his "lackluster" ride I wasn't about to keep up with Steven but I would have been insight of him crossing the top. Yay!

Jo and I went to Peppers Manor House over the weekend. Very nice place. We spent most of our time relaxing, reading and eating in front of the fire. Some photos of the house here.

Wednesday, August 24, 2005

I've got some time off work so I decided to make a todo list. I made the mistake of putting it up on the notice board at home and telling Jo she could add to it. Let's just say, I don't have to worry about not having anything todo anymore ;-)
Anyway, on the list was to donate blood and I can happily cross that one off now. I've not donated blood for a few years now. Blood supplies are running low so if you're thinking about donating, now would be a good time. Checkout where to donate if you're interested. There are even mobile blood banks around the country (schedule available online). 80% of people need blood products sometime during their lives but only 3% of eligible people donate. Here endith the lesson
