A regression for WPA2 - 18:20
I thought maybe there was some problem with my laptop hardware and maybe the iwl4965 chipset simply would not do it under Linux. However searching online suggested I should be able to make it do WPA2. Thinking maybe the Ubuntu people had done it right and Debian was missing something I tried booting a Jaunty live cd. I also discovered the rather neat feature of suspend to disk (hibernate) in that you can hibernate your computer, boot off a live cd, use it, reboot and have your existing session come right back up normally on the next boot. Anyway I booted up Jaunty and tried to authenticate, still failed in a similar manner to my Debian installation. Out of curiosity as I had heard of hardy working I booted my laptop on a hardy live cd. So network manager and iwlagn driver combined on either Debian sid or Ubuntu jaunty had failed to authenticate. Ubuntu hardy on the other hand, using an older version of network manager and the iwl4965 driver in the kernel worked fine. WPA2 authentication and use on the ANU Secure wireless network. So now I need to find out where the regression has happened that means WPA2 is broken in more recent releases of the software (kernel drivers, wpa supplicant, network manager) on either Debian or Ubuntu.

Sydney again this weekend - 16:49
Some mountain biking on Saturday at the send off, probably no exercise Sunday (unless we go swimming) (unlike last time), still it should be nice even if I have to deal with Sydney. Mon, 29 Jun 2009
Lots of time on foot - 11:09
Early on in the event my camelback bladder burst when I slipped walking down off Mt Ainslie and landed on the backpack. Fortunately our course was taking us around 500 metres from my house so we made a detour 20 minutes later and I got a new bladder and changed out of my soaked jersey. Later on on Black Mountain we made a small nav error coming down from the summit trail looking for a 40 point control. We started looking for it too early above the fire roads. It took us about 8 minutes of searching and looking at land features to realise they did not match, look closer at the map and realise we had to head down another 100 metres in a gully to find the control. Paul was a strong team mate and we got through the day well, today I hurt a lot I can definitely feel I did something on the weekend. Sat, 27 Jun 2009
Some races this weekend - 17:01
Tomorrow I will be doing the 2009 ACTRA Metrogaine with a friend Paul. As Paul is fit and keen to have a good crack at it I suspect we will both be pushing ourselves pretty hard for the 5 hours of the event. Ahh well I need to do more stuff like races this weekend to HTFU from time to time I think. Fun has been and will be had. Fri, 26 Jun 2009

Raining on those adamant computers - 15:38
As I stepped out the door to get the bike from the garage and head out riding it was pretty damn wet with some precipitation falling. When I got to the ride Ron pointed out that my checking of the weather radar for conditions was a very geeky way to see if I should ride. I admit, through my extensive testing of the claim that it was not raining I had pretty much decided the claim was false by the time I got to Dickson. We went riding and got pretty wet and cold anyway, however I was amused later to hear that Simon (jokingly I am sure) has on occasion checked the weather radar from his iphone while actually out riding in a group and claimed it was not raining due to the radar image even when the experienced evidence at that point in time said otherwise. Of course computers are never wrong so we must believe what they say... Mon, 01 Jun 2009
An interesting languages comparison - 15:45
Back in 1999 and 2000 I put a pretty trivial example of a single problem being solved in multiple languages online. In this case scanning html for entities, largely because I was mildly interested in how different languages and the different implementations of them may solve the same problem and the time it would take. I say mildly interested because it is such a trivial example and because I did not put much effort in. (I was amazed a few weeks ago to get an email from someone rerunning these to see if recent Java implementations had caught up to c yet). The person who wrote this speed, size and dependability post put a lot more effort in and actually was able to draw some interesting conclusions about languages and how they work and develop over time. For the geeks out there I recommend having a look. Thu, 28 May 2009
The Annual May Zombie post - 17:46
However a recent post on boingboing has got to be the best so far this month, in the fun ilk of Randall Munroe's limerick db (hilarious stuff there) is a large collection of Zombie Haiku. To win a copy of the game Plants vs Zombies (also appearing on there this May) readers were asked to submit Zombie Haiku in the comments. And remember

The reboot worked - 13:18
Bones was my favourite TOS character and in the new movie, Bones is awesome and cool and completely and utterly what I would expect him to be like. I was entertained to see Chris Pine even got the slouch in the captains chair looking like TOS Kirk, Scotty was great and even though it bought the characters together in a different way it all seemed to fall out well. I tend to agree with many comments suggesting the Uhura/Spock thing was a bit weird, but it did not detract from the rest of the movie too much. I saw the movie with a friend who was not particularly keen on seeing it, but thought it was potentially going to be good, she was blown away with how much fun it was and how good the movie was. Definitely worth seeing I think. Mon, 18 May 2009

Lake water testing and areas - 11:41
The thing I noticed is if you do not know the boundaries of each area of the lake or what the parts of the lake are called these may not make much sense. So I went looking for maps, I found some descriptions of the regions on the Wikipedia article which helped. Still no good map was found until I stopped searching for terms such as tarcoola reach on the natcap site and Julie pointed out to me the page on their site about Lake Burley Griffin and Surrounding Parklands. The map available on that page is not really large enough to read all the writing on it, however it shows enough detail to get a good idea of which areas you can use from lake closured. I have copied it to my server as the file is hidden behind some javascript view thing otherwise. I would love to see a larger version of this image (or a scalable version) if anyone knows where it is (possibly on display at Regatta Point I guess). At least for now it appears we can still paddle down Yarramundi Reach from Yarralumla bay. If we get a bit of rain over the next few days and the weather remains cold we may even have the Algae levels lower enough to use the whole lake again for paddling. I am making this post largely so I remember where to find a map of the lake showing me what the names of the various areas are. Thu, 14 May 2009
More open source required in government - 12:36
Today Schneier had some information on breathalysers that due to court orders finally had the source made available for some analysis. This is not the same breath test system as used in the Florida case from what I can tell at a glance (this was a New Jersey case), however it definitely opens your eyes once more on how crap closed source software can be (and yes I admit lots of open source software can also be crap) and you will have no idea, and no way to fix it. Any software used in law enforcement in such a way that it could be so incorrect or wrong and yet still cause someone to lose their licence or gain a criminal record really should be opened up, at least to the agency/government/force using the software, if not open to all people.

Mothers day, how mum turned out to be a strong paddler - 11:14
So this weekend past I finally was able to go and participate in the Mother's Day Mayhem event with her. I drove out to her place at 7:30am and made her pancakes (she fortunately quite likes pancakes I can eat made with soy milk, ground linseed and no eggs) then after breakfast we went over to Yerrabi pond where the event was being held this year as Lake Burley Griffin was still not open to secondary contact use in the river near the club shed. Due to some confusion around the days paddling I was not sure if we were racing or just going for a leisurely paddle at first. I also did not know if we were paddling around the edge of the lake hugging the shore or coming back past the start area. So we started paddling and I saw the other boats go off with people paddling hard, so I picked up my pace and Mum simply matched. Way to go Mum. After turning around the first island I started heading across the dam wall to hug the shore all the way around and another boat knowing where we were supposed to go headed back on the shorter course, so I turned there and caught back up. Mum was able to hold my fast stroke rate for almost the entire 2 km and we ended up coming home first. Way to go Mum, for someone who had never kayaked before and had not paddled a canoe for more than 20 years I was impressed. After the paddle event we went back to Mum's place and then headed out so I could treat her to lunch. To finish off the day I headed out to see Wolverine at Dendy with some friends. Fun and entertaining movie, nothing spectacular but good to watch none the less. Fri, 08 May 2009
A new bridge should be more useful. - 15:22
I am firmly in the camp that if money and construction effort is to go into a pedestrian/cycle access bridge across the lake in Canberra it should be somewhere that genuinely would improve the cycling and pedestrian access to parts of the lake and Canberra. I know it is not visible from the centre of the city area or from central basin but I must say the only location that makes much sense to me is for a new bridge to go from Black Mountain Peninsula to Weston Park. Either of the crossing points on this map would be good. Having a bridge across here would speed up access to many parts of the lake and Canberra and provide more route options for self propelled people to get around the city that would actually be useful. The other major advantage is that sail boats do not race down toward Yarrmundi reach thus the bridge may not have to be high enough for large sailboat mast clearance. However it is a much shorter span so it would be a lot cheaper no matter what height it had to go to. Update: I have since first posting this heard that sailing does sometimes happen as far down the lake as the Governor General's place, thus a bridge built here would still need to accommodate masts passing under it. The span as noted is a lot shorter so it is still going to be cheaper here than at the currently mooted site. Wed, 06 May 2009
Reminders and bugs - 17:16
As for the bugs thing, I think there is a bug in the Ubuntu 9.04 libnss-ldap, I found a problem where it was not reading something configured by the install from ldap.conf and I need to do a little bit more testing before submitting a bug report. Mon, 04 May 2009

My first Yerrabi Multi sport - 20:22
I rode my cyclocross bike in the race and I think it was a perfect choice for this course, I managed to do the 28KM bike leg in just over 1 hour including transitions and felt pretty comfortable for the entire leg. My total time for the race was 2h8m (for a 4km run, 5km paddle, 28km mtb and 4km run) which I was fairly happy with. Fun was had, thanks to the local Sri Chinmoy Race Team for another good event. Sat, 02 May 2009
Check sooner next time - 18:04
Previously we have had a number of problems with the heater in the house, though the one here now is a fairly new gas central heating unit so probably should not play up. Still stumped for what was wrong, I was reading the manual from the website for the heater and the error code was saying something about it not being able to light the heater from 4 attempts each time. It finally occurred to me to go outside and look at the gas meter, and well what do you know the lever on the meter had the gas coming into the house turned off. You know what, heaters really will not light when there is no fuel available for them, kind of funny that. Next time I may try to remember to have a look there sooner, no idea why I just assumed it was still turned on from last year (though I do not remember ever turning it off). Fri, 01 May 2009
Lesser exercise week - 21:14
Monday I headed out for a fun paddle in Matilda in the cold with one of my house mates, Tuesday I did the Bilbys track running session, Wednesday I did the morning road ride, Thursday I did the morning swim squad. Finally today I did the morning mtb ride and tonight did the evening swim squad. Feeling pretty good, will probably do a road ride tomorrow and then on Sunday I am competing in the Sri Chinmoy Yerrabi pond multi sport race which should be a bit of fun. As for why I tend to be doing two things on many days the last few weeks I do not really know, I have no current goals in mind, though I guess it suits long term goals, I can simply tell anyone who asks why I am out exercising that it is Jindabyne Multisport prep. Today I also entered the Angry Doctor 100 KM mtb race AROC run in September which will be a nice wind down a week after the World Mountain Bike Championships are over in Canberra. Sat, 25 Apr 2009
Anzac Day Epic 2009 - 22:09
My GPS trace from today is a nice 71km, I have not yet uploaded any photos, however Morgs has some online to show off the cold and wet and the fun too. Turnout was reasonable considering the conditions, though the lack of Crash and JJJim was strange. People there were
Matt - Ibis carbon goodness Fun was had. Thu, 23 Apr 2009
How many problems are ignored - 12:29
I do wonder how many people tend to do this, unless you get a repeat failure from some brand a few times it is far easier to simply go on with life and not spend the time making a customer complaint with such a small value item. It is only as the value of a failed item increases or the ease of making the complaint decreases that you would make the effort. Of course everyone will have a different graph of where these things go and the area under which you would make the effort. Tue, 21 Apr 2009
Another change to cache_timestamps for perl 5.10 - 11:28
It used to be something like this
{
my (%h1,%h2);
sub wanted {
$h1{$File::Find::name} = "someval";
}
find (&wanted, "topdir");
}
However when I changed to perl 5.10 though the assignment seemed to work (blosxom runs without -w or use strict enabled) if I tried to display %h1 inside wanted or tried to use it like a hash I got a weird error "Bizarre copy of HASH in refgen" at the line of code I tried to use the variable as a hash. Looking at other uses of File::Find it seems everyone used anonymous subroutines from the call to find. I have changed the code to do the following.
{
my (%h1,%h2);
find (sub {
$h1{$File::Find::name} = "someval";
}, "topdir");
}
And now the hashes are in scope and not some so called Bizarre copy any more. The code for the cache_timestamps plugin can be found here and details about cache_timestamps are in my comp/blosxom category. Update: found some details, rather than searching for the error message I started searching for variable scope changes in 5.10. Found this page talking about state variables being available in 5.10 as my variables are not persistent across scope changes. Sun, 19 Apr 2009
Morning run in Sydney - 09:14
Starting with the slow group we had a pleasant 20.7km of running at 5:40 pace chatting with the people there and enjoying the cool nice running conditions the morning had dished up for us. Now for the rest of the day in Sydney after some good morning exercise. Sat, 18 Apr 2009
Some Sydney food - 19:17
First off we headed to a place in Newtown called Macro Cafe, the coffee was alright, although it was not a Vegetarian place they did have scrambled tofu for breakfast. Jane had a mushroom dish which had goat cheese and some other stuff, according to her it was remarkably not good for the ingredients. My scrambled tofu was alright but something was off about the spice or way it was served and it was not as good as I come to expect in many Melbourne Cafes. Lunch on the other hand was had in Glebe at Iku Wholefood on Glebe Point road, a chain of stores around Sydney (10 all up), they are a Vegan cafe, with a whole variety of interesting and yummy mains and desserts ("cheesecake" made vegan with tofu and other yummy ingredients for example). I had a rather yummy tofu pocket and a pasta based fritata. Jane had a bean and rice dish with two different flavoured pinto bean dishes, the sweet potato and arame was really good and the pinto bean tomato casserole was also enjoyable. Yummmmmmm. I wonder what we will do for breakfast tomorrow... Mon, 06 Apr 2009
First 24 hour race since February 2006 - 11:12
I was in a 4 person team with Marea (with whom I have competed in Polaris many times), Ian (Marea's partner, who has raced the Scott 24 hour solo and other such things) and an ex Canberra now Brisbane mtber Ged. All was going fairly well until Ian after doing 1 lap on Saturday decided he just could not get his head around the idea of racing 24 hour races any more and wanted to simply do other riding, thus he was not keen to ride any more. This left us as a 3 person team. I headed out for my 4th and 5th night laps doing a double at around 10pm with our new race plan to do doubles until around 4:30am then singles until dawn and maybe get a friend, Dave A, to ride some laps on Ian's bike in the daylight. However while I was doing my double lap Marea and Ged decided we should rest overnight. I was not incredibly keen on many more night laps so we all went to sleep for a few hours. In the end I rode 6 laps, a total riding time of around 5h40m and felt alright afterwards, though a little bit flat and energy drained today. Paul set a fantastic course and the rain dump on Friday night was perfectly timed, there was no dust all weekend and the course was tacky and cornering was fast and secure the whole race. I rode one lap on the single speed, however with the chain coming off three times I discovered I needed to take a link out of the chain to get enough tension into it, I did not feel like doing that so rode the geared bike the rest of the time at the race. I was reminded that a duallie would have been faster as you can keep full power down the whole time over bumpy terrain, however it was one of the best hardtail courses around anyway especially with good line choice.

Recent movies - 15:06
Duplicity was also good, I have a habit of spoiling movies and have to work hard to stop myself spoiling this one. I think it is let down a bit in that it is a little bit hard to care about any of the characters, however the twists are fun and the premise is entertaining and carried out well. Next on the movie agenda I think I will in fact make the effort to go and see the new Star Trek movie, I did not bother seeing the last one, however I look forward to seeing if this reboot of the universe works somehow or not.

Swimming injuries - 17:00
In the lead up to Jindabyne I noticed my left hand was often swollen on top from this making my bike gloves feel tight on my left hand. I am sure I will stop getting this bruising as much as I swim more and get more used to being in the pool over time. On another note, I was glancing through some old entries on my diary and noticed one that fairly nicely shows how little I ride these days compared with times in the past. As noted the other day I have not done many days over 100km in the last 18 months (the ride up to Corin on Sunday just now was fortunately another one clocking in at 105km). Back in September 2004 I commented on getting my km count up from a week of only riding 230 km during the Monday to Friday week, so I headed out on the weekend to clock up 281km (175 on road bike and 106 on the mtb) over the two weekend days for a week total of 511km.

My geek credentials in question - 17:38
I own two of the witch books but have never yet been able to read more than the first few pages without getting bored and putting them down, so I doubt I have any interest in those I do not have. Anyway thinking I should attempt to rectify this lack of ownership involving some good Pratchett books I headed out to Canty's second hand book shop in Fyshwick today to see if they had any of those I do not have to buy. Alas it seems their Pratchett stocks were low as only two of the YA books were there and nothing else. I guess it is probably time to trawl through some of the other second hand book shops in Canberra, if only I can find the time. I wonder if my geek credentials should be called into question for not having them all? Thu, 19 Mar 2009
Jindabyne Multisport Classic 2009 - 17:28
Fortunately I did, though I did not speed up much on last year. I felt fantastic for the first 6 or 7 hours of this race, then sometime during the long run up to sawpit I no longer felt I had enough left in the tank to go hard. I had been hoping that pacing myself I might finally feel I could start putting some effort in at this point, however I was unable to get my HR over 130 for the rest of the race and pretty much crawled all the way to the finish. Once again my worst leg was definitely swimming, compared with good swimmers in the solo field, such as Alex, I lost almost an hour. Looking at times for excellent swimmers such as Shanyn I lost more, however I can not imagine I will ever swim as well as she does, and I was racing solo anyway. My current plan, rather than stopping swimming again until I start getting ready for this event again next year is to continue to go to at least one coached squad session every week. On a seeming tangent now, I notice in my GPS/HR training data that since I bought the Garmin in August 2007 I have the distances of all sessions I have done (riding, running, paddling) listed to inspect and view the maps and data from. In that time I have only done a session in which I travelled more than 100KM on 6 occasions. This is pretty pathetic when you consider how easy it is for me to do a road ride over 100 KM. Two of these sessions were the Hawkesbury classic paddle race in 2007 and the Jindabyne race I just finished on Sunday. So I think we can see when compared to how I used to do long road rides at least once a week, generally a longish mountain bike ride every fortnight or so my riding is definitely down on what it once was. Sure I kayak and run now days but none of them tend to be longer than 2 hours very often. Getting back to the race I think my body just was not ready for more than 6 hours non stop and was not working as well as it could after that time. Also the multi discipline nature of the event was something I had not prepared for well in the lead up. For next year I will definitely need to do more long stuff and make sure I am feeling more ready for such a long stretch out there at intensity. I must thank my support crew, Kerry, for her help all day. She did a spectacular job and was organised all day and got kept me going despite never having done support like this before, also thanks to Ron for helping her out most of the day. Without their help and some generous help from many others I would not be able to do the event solo. I did do more swim training before the race this year and I think it showed as I was able to get out of the swims reasonably fresh feeling and was not even the slowest solo competitor in them all. The long ride though I was once more crawling through it, really is spectacular and I recommend it to any mountain bikers who like epic feeling bike legs and big hills and alpine country. The long run is also though a really lovely walking track and when not suffering worth admiring. Race coverage wise, I have a few photos on my camera but am being a bit lazy to upload them. Sri Chinmoy's gallery page for the event has a fair few (those with me in them are finishing the second bike, transitioning to long run, start of first run, background behind Libby running, start of fun (techy) bike leg, running through Thredbo river picnic area, first swim start with Julie and Alex and getting out of a swim. There are good shots there of Alex (who won solo mens) and Julie (won solo womens) and a lot of my other friends up there racing. Also there was a professional photographer up there, Greg Long and his event photos are pretty good. Anyway I enjoyed the event and have a definite interest in trying to do better next year, a spectacular (and hard) day out. I still think more people should enter, it is more fun than Triple Tri, shorter legs, better scenery, something different (though triple tri is itself a lot of fun). Also more solos would be cool (lets hope Zoe, Danielle, Libby and others may be keen to enter next year so it is not just Julie in womens). Thu, 12 Mar 2009

Missing swims - 16:46
This week I have not been able to swim on either Tuesday or Thursday, though I had been planning to, I simply ended up with too much stuff I was doing out of the office on both days, a lot of it for CORC, that I could not justify being out of the office for a whole additional hour for a swim session. I should have made the effort to swim on Monday after work, however hindsight is always useful this way. A week and a half to go before Jindabyne now, I just have to hope I am relaxed and comfortable enough with the swimming to get through all three and not lose pace too much. I suspect the hardest will again be the final swim just trying not to cramp and make it through that one will be a big challenge, I already tend to cramp up very easily swimming and once more staying hydrated at Jindabyne will be a constant battle. This week the Wednesday night paddle time trial did not happen at the club as molonglo reach was also closed to secondary contact sports. A few of us were hoping to do a time trial on the rowing course on the lake as that is open, however it was one of the windiest days in recent times yesterday and there were white caps on the rowing course so when we got there it we were not venturing out of the safety of the sheltered areas. The normal paddle time trial is 9.6km on the gps. The rowing course is 1.8km so 6 laps of it (3 times out and back) would have been 10.8km, so if it had been nice and calm it would have been a tougher race than we normally do. Ahh well maybe some other time that will work as a replacement race. Even though there was no group run on Tuesday I still had a good run from home to the top of Mt Ainslie and back via Dickson ovals. That I was able to keep running all the way up and hold a reasonable pace (even though HR was above 170) actually makes me feel I should be alright on the long run at Jindabyne next weekend. With the long weekend coming up, I hope to get a few good sessions in, Sam is keen to do some long stuff on Saturday (maybe a run, a paddle and a ride if she can leave Ben with the kids for that much of the day, we will see). I was keen to do the AROC urban race on this weekend however almost none of my friends seem to be interested in it this year which is most unusual. Danealle and Danielle are doing it but everyone else seemed a bit hohum and are off doing other stuff. Fri, 27 Feb 2009
Still not running enough - 11:44
Wednesday afternoon at the paddle time trial the wind was pretty nasty and slowing everyone down a bit, then I got a 50cm stick caught in my rudder somehow and the boat was not steering properly. So I stopped to get it out, thus my pace was way off, so I kept t slower for the rest of the time trial and was 3 minutes slower than the past two weeks. (actually 4 minutes slower if time stopped is included) Yesterday's swim however felt pretty good, well by that I mean my lats and forearms were sore afterwards, which I hope means I am working my arms better in the water and getting more forward motion happening. I do not feel up to a lunch time run today, so will need to head out for at least one longish run on the weekend I think. Probably going to head out on the road bike in the morning, to see Libby's new road bike and to do some hills. Tomorrow arvo I want to make it over to Stromlo to check out some stuff at the Stromlo Running festival, I may ride there for that. Nothing else is set in stone yet. Wed, 25 Feb 2009
Stardust comparison - 10:56
It is interesting to see how much the stories diverge in places and yet how they tell the same story well and also how good they both are. The stories are different and the movie definitely has a slightly more Hollywood sort of end. The book, though short, provides a lot of detail that can back up the movie well, it also deals with conflicts differently. I also think it makes more sense at the end how Tristran and Yvaine travel together (although the movie does not explicitly say that did not happen, so again it is just an extra detail that may not have made sense squeezing it into the movie. The flying ship is not quite such a large part of the book, however I think that is partly because they had Robert Deniro in the movie and wanted to do a lot more with him. Anyway I love both the book and the movie and recommend them both highly as good entertainment. |
