Finally a fresh way to look at user interaction

2007-03-07T23:05:00.000-08:00

It has been my belief for some time that we are caught in old tired rules for user interaction, click the left or right mouse button, drag and drop, drag select and of course double click. All the these actions have been around since the 80's, meanwhile, the computing power we have at our disposal has gone through the roof and the amount and type of data we work with has moved grown even more.

Something has to change, the old techniques we used in the 80's and 90's were fine then but they really don't address the problems of today. Now, I'm not saying computer interaction is being ignored, far from it, it's just that lots of the work is really variations on and existing theme.

It is because of all of this that I find this work so refreshing. Watch the videos on the both pages, it gives you some idea of how you can interact with large and complex data sets. Sure, a lot of this is very experimental and doesn't address many aspects of today's computer use but it is a step forward.

I look forward to seeing where this goes and what influence it has on the industry in the coming years.

Strange game

2007-02-17T14:03:00.000-08:00

Not sure what this game is all about but it is addictive and rather interesting. My best score so far is 2,799.61 meters.

Viral effects and Subversion

2007-02-13T20:52:00.000-08:00

So way back in October I had the opportunity to incorporate Subversion into a work project, now this was a fairly big deal since our company has been a Source Safe shop for a very long time. There was also the small fact that plans were well underway to migrate all development to Microsoft's new Team Foundation Server.

Call it a case of fortuitous timing and a genuine need for some good version control and branch management and of course a little direct force to put in place a solution when nothing else was immediately available.

My experience with Subversion had been somewhat limited up to October, sure I had used it but only for smaller personal projects, never for large projects. Things have changed now, me and a small team have been using Subversion daily for a pretty large code base and have learned a thing or two in the process. Working with Subversion and it's companion software Tortoise SVN have proven to be a pleasant experience and have allowed us to work with the source in ways that would have previously been a pain. For example, I work on a laptop and routinely work on the code at home with or without access to the repository. This has never been a hinderance since all the source is write enabled and you can perform diffs against the base version at any time without network access. Even when you do have network access through VPN or what ever, I've found the speed and reliability of Subversion to be very good, operations perform just like I was working on the companies internal network.

Okay, so I'm gushing over Subversion.... it is not perfect, what software is? However, after years and years of using Source Safe this is a very pleasant change. Now, one might ask what are these 'vial effects' you mention in your title? That is where things get rather interesting....

I mentioned at the beginning that a move to Team Foundation Server was in progress in October, well, it is now February and Team Foundation Server has pretty much arrived. Build systems are being updated and tested and the client software is now being deployed. So, all of the development teams are going to move to Team Foundation Server within the next couple weeks and from my point of view Subversion will be removed from the daily development activities.

Just as the sun was setting on Subversion use I got an unexpected visit from our IT person today. It started out innocently enough, he had some questions about Subversion which I assumed was related to backup related activities, etc, then as the discussion proceeded some interesting questions began to arise. He started asking about differencing of binary files and then we got into how one might lock a file so that only one user can modify it at any single point. Eventually I asked what this was all about and got a bit of a surprise..... he was seriously considering switching our documentation team over to Subversion.

I can guarantee that this would never have happened if we hadn't injected Subversion into the company in a rather direct way. It is unfortunate that it didn't become the standard for our software development but at least it will have a life in other parts of the company. Should be interesting to see where things go from here... does anyone have some good scripts for transferring change sets between TFS and Subversion? :-)

Here is another shot of the sky this evening...

A wonderful sky tonight

2006-10-22T19:43:00.000-07:00

Today was a wonderful sunny day but the rainy weather is looming, this was all to clear tonight as a the sun set and the clouds started to push their way inland. I was able to snap a couple shots from our second level window before it got to dark.

Hiking around Garibaldi lake

2006-08-29T00:02:00.000-07:00

On Sunday we got up bright and early (trust me... the cows weren't even up yet) and drove with some friends to Garibaldi lake. For those unfamilliar with the area, Garibaldi lake is a small part of a very large park called.... you guessed it, Garibaldi provincial park.

The area around the lake and the aptly named Black Tusk mountain peak was quite remarkable, lots of wild flowers and interesting vegetation at this time of year.

Without further ado, here are some photos of the area. This first set of photos are from and area known as Taylor meadows which is one of two designated camping areas.

And this panorama gives you a better feel for the lay of the land.

After going through the meadows, we reached an area known as the Cinder Cone which is the home of a small volanic cone. The landscape in this area completely changes and in some ways looks more like a moonscape than a volcanoe.

After a fairly big decent to Garibaldi lake, we just hung out for a while at the lakeside to recharge before doing the 9 km trek back out of the park.

Most of the scenery going out was either lots of trees or the occassion lake view, however this particular area was incredibly rugged and was certainly worth taking a moment to appreciate the forces available to mother nature.

At the end of the day, our hike took us about 30 km and at least 800 meters of vertical assent. All of us were certainly feeling a little tired at the end of the day, so on the way back to Vancouver, we stopped in Squamish for a little bit of ice cream. :-)

Networks gone bad

2006-08-03T18:01:00.000-07:00

Sometimes networks get really bad and here is the proof.

Boring job? Listen to this!

2006-07-06T22:58:00.000-07:00

Some of you may really relate this this remake of a popular song by James Blunt. Really tells it like it is for some people in todays work force.

Hiking on Bowen Island

2006-06-13T23:47:00.000-07:00

This Sunday we went for a great hike on Bowen island which is a short 20 minute ferry ride from Horseshoe bay, just outside of Vancouver.

This photo was taken on our approach to the ferry landing at Bowen island, the inlet is called Snug cove and is certainly well named as the cove is quite narrow. As we approached the dock we took notice of a collection of geese that were paddling about right in front of the ferry. It looked like they were playing a game of who can get closest to the ferry without being over run! Some of the geese actually waited to the very last moment before getting out of the way.

Once docked we departed the ferry and were immediately in the village of Bowen island. This is a very cute area with lots of little shops for art, clothes, a museum and lots of other interesting areas. The whole area feels very different than the city we had left just 20 minutes before.

We figured we should check the trail maps before starting so that nobody gets lost! :-)

Thereare some incredible houses on Bowen inland, this one was right on thewaterfront and is probably worth a cool million or so dollars.

Here is another house tucked away in the bush with a nice little lake in front of it. Looks like they have alot of grass to cut!

Once we starting walking the trails we came across a river with a fish ladder, for the uninitiated, fish ladders allow spawning fish to make their way up river with less work than would be required in the normal course of the river. Fish ladders are also used when it is physically impossible for fish to travel up stream due to man made obstacles.

The next several photos are just various shots we took during the early part of our hike.

Some of the terrain we covered was pretty steep, the proof is in the pictures. In a couple locations there were ropes setup to ease the climb since the trails were full of roots and could be a little tricky at times.

After all of that, we finally made it to the top of Mount Gardner, the view was spectacular, the pictures really don't do it justice. You could see a large part of Vancouver including Stanley Park all the way up the Sunshine coast.

After all that hiking, it was time for lunch, a few others joined us on the peak while we gelled out.

As we made our way down, Emma discovered she still had lots of energy so she decided to do a little tree clearing.

Another shot from a view point about half way down the mountain, you can see the Vancouver island ferry in the distance.

Saw this cool fungus on our way down and just had to snap a photo.

And of course, after doing all that hard work, it was time to treat ourselves. We went to Troll's restaurant in Horseshoe bay where we had fish and chips and beers all around.

All in all, the hike was a wonderful way to spend the day, we hadgreat weather, a little bit of cloud but no rain so the temperature wasjust right. From beginning to end we took about 5 hours to completethe hike which was a little better than 17 kilometers in length. If you are interested in hiking on Bowen island but would like an easier hike or walk, check out the route around Kilarney lake. The route is quite flat and can be completed in a couple hours giving you lots of time to explore the village and perhaps grab some lunch or dinner while on the island.

A cool piece of flash artistry that you can sit an play with for quite some time.

A bit of a hiatus

2006-05-16T23:31:00.000-07:00

Just a quick note to say I'm still alive and well. We returned from a nice trip to the Philippines several weeks ago and then I promptly became ill. Flu like symtoms turned into one of the worst coughs I've every had, which in turn meant a doctors visit (or two). After letting my immune system have a go at this bug for almost 2 weeks it seemed that a stalemate had been reached so out came the heavy artillery. My doctor put me on some antibiotics and now I'm much healthier and back into the full swing of things.

Should be more active with the blog posts once again so please stay tuned.

Cheers.

Ruby without the download

The wonderful thing about tigers....er, Ruby

2006-02-01T21:28:00.000-08:00

Over the last month or so I've been discussing various aspects of Ruby with coworkers and technical friends. In several instances I've been asked what the big deal is with Ruby, what does it bring to the table that makes it any better than Java, C#, C++ or any other language? There are many aspects of the language that I really like but earlier tonight this blog entry came across my desk and really helped outline one of my favorites.

The fact that you can alter virtually any class or object realtime proves to be an incredibly powerful feature. Of course with great power comes great responsibility and as shown with the aforementioned writeup on Rails, this power can be used to deal with real world problems in a most excellent way.

Thanks for listening.

Ruby conference

2006-01-27T23:52:00.000-08:00

For those of you who know me or have been reading along for the last couple of months, you probably know that I have been exploring the Ruby language. In my journey several others have caught the Ruby bug and slowly the sphere of influence reaches out. :-)

My experiences with Ruby have been quite enjoyable and that is why I'm forwarding this tidbit of information. Coming in April, there will be a fairly large Ruby conference being hosted in Vancouver! They have lined up 15 speakers of which several are prominant members of the Ruby community. I would like to attend however it figures, I'll be out of town and there is no opportunity to change plans at this point.

Anyway, you really should check this out and if you attend please drop me a line outlining what you thought of the conference.

Happy New Year

2005-12-31T13:24:00.000-08:00

A big Happy New Year to all. As the new year approaches all of us can look forward to new opportunities and experiences remembering that life is what you make of it. We never know what may be right around the corner.

Wishing everyone the very best in the coming year.

Using the right tool for the job

2005-12-08T22:57:00.000-08:00

Having developed software for quite a few years now, we won't discuss how long since I don't want to date myself :-), it is very easy to stick with a language you use frequently. When a problem arises, you immediately think, "how would I solve that in C++ or Java?". This seems perfectly reasonable given you know the language well and should be able to put something together pretty quick.

Just the other day I found myself in such a situation, I needed to pull apart a binary file to ensure it was being generated correctly. The code that produced the file was in java, however it was a small part of a much bigger system and thus was not easily reused for my purposes. Sitting in my chair I'm thinking how I can quickly put something together that will output the contents of the file and maybe do a little validation in the process. Using C or C++ would not be to bad but require the setup of a VC++ project, generate a main(), write some file code, etc, etc, etc. Nothing hard here, just tedious. Java was no better, I would have to create many of the same things required by C++.

It was about this point that a thought came to me, why not use Ruby? A little Ruby script could pull the file apart easily enough and there would be no need for a main and the file code would be really simple. Only problem, although I've used Ruby for a few things I'm still learning alot about the language so it would no doubt be quite a bit slower to write an app in Ruby than it would be with Java or C++ right? Well, Ruby it is, after all, this adds a little variety into my development life!

So first things first, how to read binary data from a file using Ruby? A quick web search outlined how to use the File class and the associated read method to access binary file data. After that things just flew. Quite literally, 5 minutes after I started a complete Ruby program was on the screen in front of me that would produce a nicely formatted output to the standard console outlining the contents of the binary file. Could I have written the same thing in C++, sure, would it have been completely done in 5 minutes, doubtful.

This is productivity at its best. The little program is easy to read, can be extended in no time and proves to be a valuable debugging tool. Pretty good for 5 minutes time! This just goes to show, using the right tool / language for the job can really pay off even if you don't know it as well as another tool.

It's snowing - first one this year

2005-11-28T23:14:00.000-08:00

Skiing started early this year and now we have our first snow fall in the city. It may not be sticking in all areas (ie sea level) but the upper areas are certainly getting accumulation. The morning commute should be an interesting one given that Vancouver drivers really don't get much experience with snow and as a result, they don't really know how to drive in it!

One of lifes interesting tid bits

2005-11-21T22:00:00.000-08:00

It really is the little things in life that make each day worth living, you just never know when something interesting will happen. This morning I was driving into work just like any other day except that it was quite foggy. The fog was sitting pretty low

Fog in November is unsual for Vancouver so everybody was driving pretty slow. As I pulled up to an intersection I looked over at a building complex that had its sprinklers running. You have to wonder why a sprinkler system was running when it has been wet and foggy for days but that is another story. The cool thing about this scene was that the sprinklers were spraying a fine mist which was immediately turning into fog. It was like a special effects person had setup a bunch of fog generators on the lawn. Each sprinkler produced a column of fog that went straight up about six feet before melding with the rest of the fog. All in all it looked pretty cool.

Funny how the little things can spruce up a day.

Developers Corner

2005-11-07T22:09:00.000-08:00

Many of us in the software field often have discussions about the latest tech or software development techniques. We glean these details from a variety of sources many of which we don't give a second thought to. Well today a coworker and I were having just such a discussion and the inevitable question came up, "What resources do you use to keep up with the latest tech?".

Now you can answer a question like this by rattling of a few resources that come to mind or perhaps send them a few URLs from your list of bookmarks, neither of these really covers the question completely though. I'm not sure about you but I use many different resources to keep up with the latest and many of these resources I visit only periodically. From these sites, blogs, etc I usually come across other sites that provide interesting bits, the net result being a bit of a spider web of connections. Hmmm, maybe that is why it is called the world wide web. :-)

Anyway, as a result of this discussion I thought it might be interesting to start posting sites I have found useful with the hope that others may also contribute to this list. These sites will span software development, software design, tools and technologies and probably a few sites talking about gadgets, etc.

To start of I've trolled my bookmarks to come up with a few sites I've found useful over the last while.

.Net Developers Journal - This is a Microsoft site that provides a good source of... you guessed it.... .Net related info.

O'Reilly OnLamp - The OnLamp site has been a favorite of mine for a while due to the combination of well written articles and coverage on some of the latest developments in software tech.

Raganwald - What we have here is a personal blog that talks about software development from a variety of angles. Stop by often because if todays post doesn't interest you tomorrows may.

InformIT - All things software. Includes info on software design, toolkits, developments in the markerplace, and much much more.

Safari - Although this is a pay site, I think it is invaluable for those who want to read up on the lates tools and techniques. Safari is an online book store that works on a monthly subscription. They have an excellent selection of books and some very useful search facilities. There is a 2 week trial giving you a chance to try before you buy.

Let me know if you have a favorite blog, website, discussion group or other resource.

Pumkin Mania

2005-11-01T23:19:00.000-08:00

Halloween has come and gone and as many a year past, we carved up a number of pumkins this year. To make life just a little more interesting, we bought an extreme pumpkin carving book this year. You know, looking at the pictures it seems like the pumpkins should not be too difficult to carve.... Lets just say there is a reason the word extreme is in the title! :-)

This pumpkin is a template I found on the web and since Emma likes cats, it was a natural choice. The pumpkin came out quite nice and was certainly popular with our trick or treaters.

As I mentioned earlier, we picked up a new set of extreme carving templates. Being one that likes a challenge, I picked this template and went to it. A couple hours later it was done, doesn't look to bad I certainly need to refine my carving skills to get all the detail. Well, there is always next year!

Here are a couple of small pumkins we put in our tree just to add a little interest as people came up the stairs to our door. If you are looking for a way to get into pumpkin carving, I'd highly recommend the Pumpkin Masters books. They come in different collections several of which are good for beginners and they usually come with tools to help you with the carving.

Many friends move on

2005-10-28T22:07:00.000-07:00

We all experience times where good friends that we work with move on to new endeavors, but it is not so common to have several of them leave the company within a couple months and it is even less common to have several of them leave the country.

Alas, I've recently found myself in this situation. Don't get me wrong, I'm very happy for all of them as they move on to new and exciting opportunities, and through instant messaging we will be in touch often. Problem is, these are folks that I have corresponded with daily and whose companionship I have enjoyed a great deal.

Departures like these create a void in your life, think of how much time we spend with our coworkers and how they affect our lives, both good and bad. Every week I spend at least 40 hours with these people, exchanging ideas, discussing work related activities and sharing experiences, etc. The office environment certainly feels different now, not sure how to describe it other than it feels colder.

To my friends, you know who you are, I bid you the very best of luck in your new adventures and it is my sincerest hope that we will stay in touch long into the future.

Serenity

2005-10-02T15:03:00.000-07:00

Well last night we went to see Serenity, not sure if we were giving into lots of hype or if we were going to see a good movie. I can now say that this is a very entertaining movie.

For those not familiar with the movie, it is based on the series Firefly which was killed by one those oh so intelligent TV networks after only one season. Firefly had gained quite a following and there was an incredible response to its cancellation, including fans going to the extent of raising funds trying to encourage the network to give the show another chance.

Obviously Firefly never got the opportunity to film another season, thus the original founder of the series, Whil Wheaton decided to make a followup movie, and Serenity was born. Even though Serentiy starts where the series left off, you really don't have to be familliar with the series in order to enjoy the movie.

Serenity is a good mix of fantasy, sci fi and action genres. Although not a good movie for younger children due to some violence and scary monsters it is great for everybody else. As far as movies go I'd say this definitely rates an eight out of ten which is quite incredible given the quality (or lack there of) of todays movies.

Give it a shot, I'm sure you won't be dissapointed.

Real world version of "The Terminal"

2005-07-15T20:52:00.000-07:00

Who would have thought that you would actually see a case of somebody being stuck in an airport for an extended period of time like in the movie "The Terminal". We have not only one, but two individuals who have been stuck in their respective airports for quite some time.

Check out the full story here.

Apples switch to Intel, what does it mean?

2005-06-10T12:44:00.000-07:00

For those who haven't been living under a rock or in some deep dark cave, you have probably heard that Apple is switching over to Intel chips for their new systems starting in 2006. Many have responded with something akin to shock and awe since this is much like hell (or whatever dark place you believe in) freezing over. When you look at this in a more detached way however, the move makes a great deal of sense for long term growth of the Apple platform.

One thing Apple has always done was make business decisisons that drive sales of the hardware. Initially, the move to Intel chips looked like they might have broken this trend since it would mean that OSX could run on non Apple branded systems. If this was to happen they would have to compete with other vendors in all branches of thier market. Most damaging would probably be the high end of Apples market where they currently make a tidy profit that helps pay for thier R&D. A change of this nature would most likely yield results like those of the early 90's when Apple allowed other manufacturers to produce clone Macs. For those that don't know, this proved to be a disasterous move for Apple as their profits were vanishing very quickly. Why by an Apple system when you could get a more powerful system from another vendor for less money?

Fortunately, rumblings from the Apple World Wide Developers Conference this week would seem to indicate that Apple will be locking OSX so that it only runs on Apple branded hardware. This is obviously unfortunate for those of us that would like to run OSX on our new shiny PC but is good news for the Mac community.

I mentioned earlier that in the long term this switch will be a good move for Apple, now I'll explain why. The PowerPC processor is a great processor in its own right and had put pressure on Intel / AMD chips in the past. Problem is, the PowerPC has not moved forward the way Intel / AMD chips have. Steve Jobs promised the Mac community a G5 PowerBook some time back, today it still hasn't seen the light of day, and the simple reason is, that chip runs too hot and consumes too much power. Compare this to the current mobile offerings by Intel and AMD, the Pentium-M runs pretty cool and has a good deal of processing power.

In addition to the chips available now, one has to look at the long term plans for the Intel line. By the time Apple is ready to sell Intel based Macs, there will be new 64 bit chips available and new chips based on the mobile core that will be optimal for systems like the iMac, Mac mini and of course thier line of laptops. John "Hannible" Stokes has written a good piece on the long term roadmap for Intel chips and what it might mean for Apple, check it out here.

Intel brings many components to the table that will help Apple with their hardware woes, one does have to wonder though if Apple has enough style and technology to make for a compelling platform. OSX is a great OS so there is hope that with Apples style and the continuing evolution of OSX they will make a good go of it.

We only have to wait a couple of years to know the outcome! :-)

Multiple PCs? Check out Multiplicity

2005-06-02T22:59:00.000-07:00

Been a fan of desktop customization software for some time, especially that produced by a company called Stardock. They produce a wide variety of tools to change the look and operation of your desktop, all of it falls under the Object Desktop brand. Recently they introduced a new tool called Multiplicity, this product is a departure from Stardocks previous tool sets as it does not help you with desktop customization. Instead, this tool allows you to use a single mouse and keyboard across multiple PCs.

Initially this may sound like a me to product, sure, many people know of PC Anywhere or the popular and free VNC. This tool however differs from these others, you use it to control other computers at your desk that have their own displays. It works kinda like having multiple monitors on your PC, when you move the mouse around, it jumps from one monitor to another. Multiplicity does the same thing with your computers, you set it up so that when the mouse moves off the edge of one screen, it appears on the monitor of your other PC.

Not only can this be very useful if you have more than one PC at your desk, but it can also be really handy for laptops. This is where I really experienced how useful this tool could be. Often I bring my laptop to the office, however when ever I want to use it, I move away from my desktop computers keyboard / mouse and use the laptops track pad and keyboard. Not a big deal, but it is a little cumbersome. Things get a little more complicated when I want to tranfer a small piece of information like an URL, image, etc. Typically I'd email these things to myself or transfer them over the corporate network. Either way it was slow and clumsy.

With Multiplicity, I can sit at my desktop system, simply move my mouse of the edge of one screen and voila, I'm now controlling my laptop. Now, I need to copy some text from a webpage, no problem, copy it to the clipboard on my laptop, move the mouse back to my desktop system and paste away. The simplicity of this software is what really makes it work so well. If you are running multiple computers at your desk, this may be what you need. Check it out at www.multiplicity.net for more details.

Sun Run 2005

2005-04-17T19:59:00.000-07:00

The Vancouver Sun Run, North Americas largest 10k marathon was held today and we participated as usual. We don't run, but it is a good opportunity to get out, get some fresh air and have a good power walk! This years event started off a little wet but by the time we got started, around 10:00 am, the weather was behaving itself.

The Sun Run is an interesting event to be involved in as there are close to 50,000 people walking, running or participating in the wheel chair portion. This basically takes over the entire downtown core for several hours.

This is at the start of the race before we got going. There are a lot of people here!

Here are the ladies while we wait to get going. Yes it is a bit wet out there, thankfully it started to clear as we began the run.

Near the starting line this was the view looking back. Not often you see that many people all in one place.

Mid way through the race everybody is doing well and having a great time.

Whew! The end of the race is near, just have to go down that hill and we are home free.

After the race we came across this cool little Volkswagen Bug that was all decked out. Of course we had to take a photo!

After all that exercise what was there to do but go have a great meal! We went to a funky little place in east Vancouver. There were some really interesting murals on the walls.

Mmmm, that is a lot of food, what a deal! Why do I feel like after all the exercise I'm going to end up putting more calories on than I took off?!?!?! :-)

Supersizerama

2005-03-31T22:43:00.000-08:00

Tonight I flipped through the channels to see if anything good was on and noticed that the movie Supersize Me was playing on Movie Central. Having never watched this much publicized movie, we decided to see what all the hubbub was about. If you are unfamiliar with the show, the basic story line is a guy decides to eat all his meals at McDonald's for a full month.

Now, you should know that Emma and I eat pretty healthy, lots of home cooked meals or eating out at good restaurants. We probably eat fast food only a half dozen times a year, so watching somebody eat McDonald's morning, noon and night for a full month was rather disgusting.

What was even worse was the transformation the poor guy went through during that month. You could literally see the color of his skin change and he gained like 17 pounds in 12 days! Half way through the show I was actually feeling ill. Looking at the processing that goes into most fast food and the chemicals that are added, it is no wonder I feel rather ill when I do eat fast food.

Well, I'm outta here.

TDD experiences

2005-03-29T22:25:00.000-08:00

Since early January some of us in my office have been exploring the use of Test Driven Development and it's potential benefits in our development process. I first became aware of TDD several years ago when the idea was just breaking onto the scene of software development. At that time there was very little information and virtually no proof that it brought any benefits to the software development table.

These days the picture is quite different, a simple search in your favorite search engine will turn up many references to TDD, including books, how to's, blog entries, etc. Although it takes some time to get used to TDD, the benefits do begin to show themselves, I had one of these moments recently. Although I've been working with some legacy code which makes using TDD much harder, I've still be able to put in a variety of unit tests. These tests are quite useful as you work with the code because you know very quickly if some existing piece of functionality has been broken. This idea is a staple of TDD, however my experience recently helped enstill this idea.

I was working on an alternate implementation of a class that had a fairly rich set of unit tests associated with it. The changes being made were rather central to the class, so I just went ahead and coded the new implementation. Now, with traditional software development techniques, you would then create some developer tests or run the code through some known conditions to make sure it behaves as expected. This works, but in reality does not provide you with very good code coverage, also, these tests are often thrown away once the initial developer testing is performed, not exactly and ideal situation.

My situation was a little different since there was a rich set of unit tests to measure the state of the code. Once the code was complete, I ran the tests (only took about a second to run them) and voila, immediate feedback on what worked and what didn't. Go back and fix the broken tests, etc. It is quite interesting how positive you feel about your changes when there are a rich set of tests that verify your code. Obviously these tests are not very useful if they take alot of time to run, in TDD, you are encouraged to produce small well defined tests that execute quickly. As mentioned previously, the few hundred tests running against this particular module all run in less than a couple of seconds!

If you are interesting in checking out TDD, check out www.testdriven.com or pick up Dave Astels book, Test Driven Development: A Practical Guide. This book is an excellent start for those looking at TDD and want to know more about it and how it works.

The birthday bash.

A bunch of us got together to celebrate my 34th birthday by doing a little bowling at The Zone, and a dinner at the Old Spaghetti Factory. We had a great time and would just like to extend a special thank you to all our friends who made the occassion a blast.

That little gal has a birds eye view of the bowling mayhem. Great smile Janet!

No, Steve isn't having any fun bowling.....no not at all....while Helen, Kevin and Masako watch the activities. The kids are in their own little world.

I'm ready for my closeup! :-)

2005-03-27T12:58:00.000-08:00

Everybody is so intent on getting the perfect score.

2005-03-27T12:57:00.000-08:00

Of course they are smiling, they had some great scores!

2005-03-27T12:56:00.001-08:00

A photo op for the Howard family, however they seem rather focussed on the bowling.

2005-03-27T12:56:00.000-08:00

Finally a strike! Time to 'strike' a pose. Way to go MarleneX.

2005-03-27T12:55:00.000-08:00

Here I am, the birthday boy, all smiles after getting a strike!

2005-03-27T12:54:00.000-08:00

Here is Lori, Alex and Kira, but hmm, where is the missing Pat?

2005-03-27T12:53:00.000-08:00

Going for a walk.

Spring Skiing

2005-03-12T14:51:00.000-08:00

Today we took our friends Terry and Jared, who are from South Africa, up for a day of skiing at Whistler mountain. It proved to be a bright sunny day and the conditions at the top of the mountain were very good.

2005-03-12T14:50:00.000-08:00

The girls flopped in the snow!

2005-03-12T14:48:00.000-08:00

Here we are in the village just getting ourselves organized.

2005-03-12T14:40:00.000-08:00

Here is Terry and Jared near the entrance to the Harmony bowl.

2005-03-12T14:30:00.000-08:00

Lots of smiles at the end of a great day of skiing. These two look like sisters with the matching tops.
