Feel free to take a look at the comments to the last post as this is a followup. You may want to ignore the snipey content devoid comments from our friend in the NZOSS community.

Herewith a follow up post that hopefully addresses the substantive questions that were actually raised (thanks Stu)

Sorry for the delay. I've been busy trying to get a high quality specification progressed through the ISO standards process. Oh and I've also managed to get outside to do some skiing in the Montana backcountry.

The issue is that the GPL aims to enforce the distribution of any derived work under the GPL also.

I do not want to release my applications under the GPL and inparticular I do not want to release any Open Source code I write under the GPL as I do not believe in the 'Copyleft' philosophy to which it subscribes.

Now that's fine. As a general rule I avoid GPL code like the plague (we do use LGPL code in some of our products). In fact our contracts at Kognition included a clause requireing neither party to the agreement to provide GPL code to the other.

So the question then comes to can I implement ODF without having to derive my work from any GPL based code.
My feeling is that even looking at the code for say OpenOffice will get me into trouble.
Likewise decompiling the code will be problematic.

I am actually comfortable reverse engineering by observation for features like 'blink', I do not believe that is going to breach copyright in the work.

But the question is, will reverse engineering by observation be sufficient. And to be honest I just don't know the answer to that question. I don't really see myself spending that much time working with ODF as I tend to agree with The Burton Report as to its likely levels of adoption and indeed the likely market segments to adopt it- selling software to people who are philosophically opposed to paying for software is unlikely to be a sustainable business. That said I did find a very interesting bit of commentary on the web about just this problem quite recently.

http://www.gnome.org/projects/gnumeric/announcements/1.8/gnumeric-1.8.shtml

"The Gnumeric team does not envision using the OpenDocument Format as its native format.

The spreadsheet part of ODF, in its current form, is ill defined and has many, many problems. For example: (1) there is no meaningful discussion of what functions a spreadsheet should support and what they should do. Without that, there is little point in trying to move a spreadsheet from one program to another; (2) there is no provision for sharing formulas between cells; (3) there is no implementation -- writing an ODF exporter consists of reverse-engineering OpenOffice to see what parts of the standard it can handle. (Note: the preceding comments relate to the spreadsheet part of ODF only; we do not have an informed opinion on ODF for word processing documents, for example.)

We may revisit this decision in the future, should the situation improve. In the meantime, we will strive to maintain a reasonable importer and exporter."

Those guys look to have actually broached the problem and to be honest that kinda answers my question. If I can't realisitically use ODF without reverse-engineering OpenOffice then I'm pretty much stuffed in terms of writing a GPL free implementation.

Went paddling and mountain biking in Idaho today.... had a blast.

Stuff has details on the refloating of the fishing vessel Kotuku.

Looking at the photo you can see what looks to be a Liferaft still strapped to the roof. Most vessels have the straps setup with hydrostatic releases so the lifeboat is released automatically if the boat sinkz. I wonder why this one did not.

OK... who's keen for a bit of a dogfood install fest this weekend?

We could combine some beers, a BBQ and some mountain biking for a cool afternoon.

Get a few people around to my house and we'll all go through and switch our machines from smelly old XP to shiny new Vista, all the while drinking fine New Zealand beer. Then while the installs are humming away we canall take off to Makara for a bit of Mountain Biking.

Anyone keen? Comment here of email me chris@kognition.co.nz

[UPDATE]

OK. It'll be at my place from 1300hrs on Saturday.

We'll do some installing. Then do some mountainbiking.
Bring:
Yourself
Your bike
Your laptop PC
Your external HDD if you need to.
Your Office and Vista product keys so you can activate your Beta
A towel and a clean change of clothes (if going biking)
Some beer

We'll all go to the supermarket after the ride for some BBQ goodies and then we may watch the Super 14 final as well

Phil, Tim and I went for a MTB ride @ Makara on Saturday afternoon. Had a blast.

Went up Koru, along Sally Alley, out onto the 4WD track then down the bottom of Ridgeline and Swigg. It was a pretty leisurely pace but we all had a hoot of a time and got filthy muddy.

Here's the profile of the ride- I really have to get myself a watch like Darryl B's... So it can talk to a wheel sensor.

If you're keento come on any of our rises do et us know!. Phil has some photos here.

I trotted off to the LVM site to get myself some 'oh I hate travelling' whitewater fix video... I get there and find that one of the key guys behind Penstock Productions, Daniel DeLaVergne, was killed by a train (8 March). I've only known Daniel via email... but this is a real bummer- one of those nasty twists of fate.

I had forgotten that it was bike to work day. As I rode from the Gym (Thorndon) to the Office (Willis St) I stumbled upon the free breakfast (well the end of it) @ Civic Square.

Anyway- IU've got right back into riding to work having shifted to Wellington. Fuel is too expensive, m car drinks it (Turbo Subaru), and I'm really liking my new bike.

I think that Phil is keen for a Makara Peak MTB ride soon. So, if you are keen for a bike ride in WLG post a comment here and we should all heahis weekend sometime.

It's funny how you really only start to vlue something if you might lose it. So it is with the Awesome Gorge section of the Kaituna River. OP Energy want to build YATLHS (Yet Another Tiny Little Hydro Scheme) on it. It's not in the guide book and from experience the first place people are going to look for some indiction that it's actually run is in Google. So.It is run. Herewith my section notes in the style of Graham Charles' great New Zealand Whitewater book.

Class: III
Level: As per the Okere Falls section
Gauge: Gates on Lake Rotoiti outflow
Length: About 2km
Gradient: Not Sure
Time: 25mins
Put In: Continue on from Kaituna Play Hole or Putn below Trout Pool Falls
Take Out: Sharp Left Hand Bend. Orange Spray Paint on River Right. Take out River Right. DO NOT MISS THIS TAKE OUT!
Shuttle: Walk back over farm tracks- see hot tip.
Character: A bit oike what would happen if they trippled the flow, halved the width and added 100m high gorge walls to a theme park water ride. A mixture of meandering bends and continuous roller coaste ride class III whitewater. Awesome Scenery and character- hence the name.
Hot Tip: Take a seak kayak ortage trolley to wheel your boats back along the portage.

The Aweome Gorge section of the Kaituna  is one of the most unique pieces of whitewater that I've paddled in New Zealand. It is wilderness paddling little more than 30 minutes from Rotorua. It is like a rollercoaster ride through lush native bush and a deep and narrow gorge. It's not difficult wite water, but, gie that Gnarly Gorge (a place you really don't want to go) is just around the corner from the take out you DO NOT wnt to go swimming in Awesome Gorge.

It starts out from the Trout Pool falls as a meandering arm stram and then slowly picks up pace through a few class one riffle rapids. Then the river backs off again before slowly pickng up pace as the gorge begins to narrow. The gorge narrows, the corners becme tighter and everything starts to push along and then suddenly the gorge tightens righ up and you're into a section of about 300m of continuous Class III white water. There are no real eddies to speak of and it's a great place to take paddling tourists without giving them too mch background. By the bottom their eyes are just wide open.

Once you exit the fast paced section you will roud a couple of corners before the rar of Awesome Gorge falls beckons. This is a drop of about 3 meter that is very similar in nature to the top drop of the Powerhouse rapid. Run it just off river left with a big boof.

A couple more corners and you are at the take out. Look for the bright orange paint. You do not want to miss this take ou.

Had a morning surf session @ Do Little Do Nothing (Kauwarau River, Dog Leg Run) on Sunday morning. Herewith the photos.

Some rock towers @ the takeout. Wish I had my SLR and 50mm f1.8 for a better depth of field.

Yup... unfortunatly Didymo has been found in both the Buller and Hawea catchments.

the didymo issue for kayakers

OK. So the week started out pretty well for me with my first sub 104kg weigh in. But then it kinda didn't really spark. I didn't do a heap or exercise (Gym Mon, Canoe Polo Tue, Run Wed, Run Fri) and so come this weekend I needed a jump start!

I got up this morning, went to the farmers market, had an apple strudel and some yummy russian deep fried pastie for breakfast...... and then ran/walked up Mt Cargil 5 minutes faster than ever before.... that's like 10% off my best time!

Just to prove it, here is my chart....

Chris Sinclair and myself and a few others have put together a paddling porno night next week.....

But of curse I'm gonna not be here and be in Redmond. But it's still gonna rock so if you are in Dunedin get on down....

Before you ask... I didn't do the poster too........

Wifey and I went to the Reef for our Honeymoon recently.

Here are some photos of our trip with Pro Dive Cairns. Second trip with them... good operation.

I've only ever had one composite lay up helmet and that was a home made glass/carbon jobbie I built away back in about 97. But when I found that Grateful Heads were flicking seconds stock on EBay for 1/2 price I snapped one up. I'm not sure what denotes a cosmetic second but I couldn't for the life of me find anything whatsoever wrong with it. Arguably there may, just may, possibly, if examined with a magnifying glass, be sme dry spots on one side... but they took several minutes of finding. The helmet is Red/Black marbled color- it looks cool. Feels really stabe on my head, the fitting system is good, nothing fancy, but good. The layup seems pretty strng but I still reckong I'd go for the heavier layup in a creeking helmet. I got the bird shape which is a Snyder design with a slight peak at the front. Looks cool even on my fat head. THe helmet has not drainage holes but the liner pretty well seals off when on your head- still wouldn't want to be in a foot pin swimmer situation wearing it though. A nice thing about the lack of drainage holes is you can use the helmet a as adrinking vessel!

Shipping to NZ was reasonable and Julie from Rain and Snow was really helpful in that she transshipped my IR Shorty Cag with the helmet to save $$$. Next time I think I'd buy a few and bring em over for frinds. All in all a great lid- it's got a few scratches already.

So my getting back into whitewater kayaking has meant some serious splurging on new gear. Back when I was relativly good I was but a poor student I had to rely on the generosity of others for nice gear. Now I've got a little more of the disposable folding stuff so I can afford to get a few nice bits of kit. So herewith my run down of the Kokatat Gore Tex Drytop- picked it up @ www.nrsweb.com for US$279 which I thought was pretty good.

As a general rule I don't like wearing a drytop- I'm somewhat of a minimalist when it comes to outdoor body adornment and I'd generally much rather just wear a shorty cag or a rashtop. So this was a bit of an adventurous purchase for me. But, my intention is to paddle all winter this year and that'll mean paddling in snowy weather- a bit much for a 3 season top even with my hi tech sub dermal insulating keg pack midrift.

I've paddled the drytop for a few sessions now- all runs down rivers but with a bit of park n' playboating along the way. It is the first drytop I have owned that is actually dry. I suffered no leakage through the seals whatsoever. The Gore Tex really does work- I think that far more than say with a moutaineering jacket you really notice the breathable fabric- when you are hermtically sealed in latex you can't healp but sweat your ass off. The workmanship and materials on the Wave are top notch certainly up there in terms of paddling gear companies and equipment vendors in general. Seam sealing done well, no lose threads. Can't speak to the durability of the fabric and jacket yet but everything indicates that it will be durable.

So what are the downsides. I think that the design is a little long in the tooth. In particular the inner tube in the double tunnel is only a draw string. This means that even though the seals keep the jacket dry you end up with any water in ya boat running up through the inner tunnel and then wicking it's way through your polyprop undies. Others have commented on the outer seal on neck being somewhat tight- I have a BIG neck (like had to trip about 5 rings off the latex) But I didn't find it too bad- smaller than might be desirable but not the end of the world.

So would I get another one? Well, I think they may have discontinued this model, replacing it with the Rogue. But, next time around I think I'll probably look at an Immersion Research Entrant Competition LX. I have the Competition short sleeve and it's not too bad. I'm also dead keen to have a look at the 2005 Bomber Gear models as they too look pretty sweet. ALl in all a good bargain was had and I'll be happy t wear the Wave all winter long. I got some Polyester base layer stuff from Krapmandthu which is great as well. I've always been a fan of Polyester garments- never been sure what drives kiwi paddlers to keep wearing filthy smelly polyprop- and then leaving it in their wet gear box in my car!

Oh... only other downside was I couldn't get red- only mango yellow.

Check out this INSANE video of some river surfing in Montreal....

Includes obligatory half naked surfer babes.....

http://www.2imagine.net/blogger2005/endless.html

Note: it turns into a somewhat lame Drago Rossi Squashtail add halfway through :-( Still they throw the odd flip turn and helix.... but I reckon the Orbit Fish looks like a nicer boat- yet to try it on a big wave though and it's a bit small for me anyway.

Over on rivers.org.nz there is a discussion about power stations- we kayaker care very much about power stations.

here is my response...

I always get my ass kicked for this answer. But IMHO Nuclear is not a bad option. Only problem with it is it is BLOODY expensive.
But, for a clean green country like ours it is ideal.

Minimal emissions (Coal/Gas to some degree), just Nuke waste which is pretty manageable or at the very least exportable. Minimal visual polution (wind farms), no damming rivers (hydro), small in size (solar), reliable (all of the above save for Coal/Gas).

The other good thing we could do is stop selling Comalco electricity at below market rates. Comalco is basically just an electricity exporting mechanism. Ship the bauxite in, use the cheap power, ship the aluminium out. Export electricity.

Remember Spokey Dokeys? The little plastic beads you put on ya bike spokes- I used to have some on my downhill bike (and my toddler trike when I was 3)...

Anyway. Gizmodo has the latest in Spokey technology- LED Spokey Dokes! How cool is that. You can program them with your Palm- now if they would only choose a decent mobile computing platform I could be tempted to splurge on some- write them off as a company marketing expense!

Here is a good wee thread on how to make your own play kayaking hole....

http://www.rivers.org.nz/forums/read.php?f=5&i=32&t=32

Kinda just blogging it so I can find it again later.....

This is a great wee playboating run. We could have done with a bit more water but we still had a great play session... lots of ends. Was a bit shallow to do anything too silly like loops though.

Seth on the hole at the bottom of the run.

Me busting out some nasty ass facials... and a few ends.. in the bottom hole.

It was a long day- about 20 hours. DUD to Queenstown and back in a day. Seth wasn't even driving!

Looks like Contact Energy are going to front up and pay for an artificial Slalom and whitewater course on the Hawea.

Details @ http://www.rivers.org.nz/

$850k doesn't seem like enough to me.... but we'll see...

If you want to import a drytop there is a duty free concession Tariff Item 6201.93.01 Ref#999063B see this document for details.

Hopefullly this will be Google useful for someone later on.

P.S. Hopefully this entry will also prevent you from having to go through the 'eye opening' experience of searching for WATERSPORTS jackets with LATEX RUBBER seals on Google..... My Word it is interesting what some people get up to!

I have a sore bum this morning- did 110km on my MTB on the weekend- raced in the Rail Trail Duathlon.

We shaved a few minutes off our last year time... I had a puncture about 10km into the second day bike leg which kindaq stuff everything up a bit.

Feel a whole heap better than I did after the event last year though. Heading up signal hill with Garry the the Mad Scott and Toby (Dogblog Dog) for some downhill action after work.

Check out this sweet pic of Stephen Wright Air Looping.... that is just such a cool shot!

Spent the weekend kayaking in Rotorua. Had a blast... been a while since I did much whitewater kayaking- I used to be a national representative and pretty competitive freestyle paddler, but work got in the way.

Caught up with one of my old friends Donald Calder who owns what has to be NZs best Kayak Shop- Sunspots http://www.kayakshop.co.nz. Paddled the new Necky Orbit Fish which I reckon would be a KICK ASS boat on a wave, but probably a bit small for me in a hole, especially a little hole like that on the Kaituna. Thinking about a Jackson Super Star- had a sweet bottom hole session with Stephen Wright and Devon Barker from Jackson Kayak and Nat from Sunspots. Steve was throwing so many airloops it looked like childs play.

Defn. gonna get a bit more paddling under my belt this year. I wasn't actually too bad on the weekend- hit sweet lines on the main Kaituna Waterfall- first time I've run that river in over 4 years. And could still throw down half a dozen or so cartwheel ends with a split left to right.

Was fully clueless when they all started talking about Space Godzillas and Tricky Whu moves.

Also got out on my mountain bike last night for a good session down Signal Hill here in Dunners. Had to walk a couple of small sections and passed up on most of the big jumps and drop offs. But, still had a good time and it was sure better than watching TV.
