One very powerful question to ask yourself, if you run a business of any kind, is "what business are you in?" Another way to ask it is "what needs do I meet?". It's easy to say "I'm in the software business" or "I'm in the consulting business" but more people are saying "I hate the way we <something in their business>" than are saying "I wish I had new software" or "I wish I had a consultant."

This Harvard Business School article even says people don't really buy drills, or that isn't the need they are meeting when they go buy a drill - they buy holes. They want holes, and they buy a drill as a way of getting them. The only way you can sell them your drill is to relate it to holes. Being lightweight, for example, doesn't matter to someone who only plans to make a few holes at a time. But it's really important to someone who is going to make a lot of holes and has to slow down the pace because their arm aches from holding the heavy drill. Being cordless only matters if you can think to say "make holes anywhere!" to the purchaser. And so on. The rest of the article helps you try to understand what needs your product or service meets, and therefore how to adjust it or sell it so that you sell more of it.

I've said for years that we're in the problem solving business. We solve people's problems. We're more likely to use software to solve them than to come over to a client's house and build a shed in the backyard or mow the lawn - but we're not so much in the software business as in the problem solving business. If I write great software that doesn't help the problem, I've failed. Often our advice on process is as valuable as the software we write encapsulating that process. And of course when we're mentoring and advising other developers, we need deep technical chops but we need to remember that the mentee or advisee has a problem (our UI looks stale, we have to exchange information with a new business partner and don't know how, our application blows up under certain circumstances and we don't know why) and we are there to get that problem fixed.

As the economy worsens you are more likely to stay in business if you are sure what business you are in. It isn't obvious.

It's so hard to remember, while you attend a conference, that the convention centre is essentially a blank canvas on which your conference is drawn. Between shows most of the space is a giant empty room with concrete walls and floor. All the lighting, draping, signs, and screens are installed for the show itself - even the chairs are temporary. This amazing timelapse video shows you the keynote room at PDC over the days before, during, and after the show. One of the things I like is that you can see how often the keynotes were rehearsed in the actual room on stage with all the screens going. Full-on dress rehearsals are vital to a good presentation.

It's about 6 minutes long and parts of it are a bit dull (imagine what they would have been like at normal speed) but I'm glad I watched it.

Recently, as a meeting wrapped up, one of us was taking on an action item to adjust the due dates on a large list of work items. We had gone through the meeting saying "put that for the end of next week" or "put that for middle of next month" and there was a good chance that too much stuff had been put into some of the buckets. He said "I'll go through on a first pass and put the dates as we agreed them, then I'll send them out for everyone to review." Makes sense. He continued, "Once we see them all at once if we need to postpone some, or prepone some, we can." And part of my brain went "prepone? What the -- oh yeah, I get it."

It's quite useful really. People say that "move ahead" and "move forward" are perfectly clear and you can't get confused by them. The problem is, half those people say it's clear that moving forward means to an earlier date and half say it's clear that moving forward means to a later date. Oops.  "Move earlier" is ok, but I quite like prepone. I'm going to see if I can use it with a straight face. BTW I did a quick search, and it's an accepted and generally understood word in South Asian English. I'll see if I can do my part to spread it to the rest of the world.

For a long time now, Google has been interested in what we search on. I remember reading an article in late 2001 that described a visit to a Google building with a screen on which search phrases scrolled by in real time. To my great surprise one of the phrases the author listed was a search I had performed myself in that time frame. Today, someone has had the insight that people search for certain keywords because of things that are happening around them.

Public health authorities the world over try to measure the frequency and severity of various infectious diseases in order to spot epidemics and pandemics in time to do something about them. For the flu, they ask doctors to report what percentage of the cases they see each week are Influenza Like Illnesses - as this percentage rises it is safe to conclude the amount of flu in the community is rising, even though not everyone with the flu goes to the doctor and not everyone with an ILI has the flu. These numbers take about two weeks to gather and are released publicly so various levels of government and quasi government can react to them.

So the Google insight was that people search for words like "fever" or "joint pain" when they or someone they know has an ILI. (I actually don't know what search terms Google is counting - it might only be the word "flu" for all I know.) These aggregated counts are available immediately with no waiting while people tally and report, tally and report up the chain. Take a look at the correlations:

Wow! That's a pretty amazing relationship between those lines. And instant results instead of waiting two weeks could make a real difference in treating an outbreak. But I am not sure how I feel about it. It's almost creepy, yet at the same time it's very cool. How can you be sure this ability will always be used for good?

This month's meeting is November 25th. Chris Dufour will speak on Building Silverlight 2 Data Applications. The meeting is at the Whitby library, but please register so the food count will be accurate.

Also on Code Gallery, in addition to the Vista Bridge, you can find an interesting bit of guidance for those developing Windows 7 applications. This is 43 pages of "what is special about Windows 7" written for developers. Curious about touch and multi touch? Ink? The new taskbar, ribbon, jump lists? Libraries? How to handle previews and thumbnails for your file type? Wondering what Windows Web Services are and how they differ from WCF? (quick answer - WCF is managed, Windows Web Services is native C++ - expect more on that from me when life calms down a little.) It's all in here, with plenty of screenshots. From here you will know where you want to drill more deeply, and you will know the names of features, which is usually key to figuring out how to use them.

http://code.msdn.microsoft.com/Win7DeveloperGuide is a good starting point, and you can join discussions and so on. The Downloads tab will get you the document in Word or XPS format.

Friday night wrapped up with a reception in the speaker room where we'd been working all week. Some of us (including me) were a little slow to switch from workin-on-my-laptop mode to hangin-with-my-speaker-buds mode.

That's Rob Windsor in the foreground and Brian Harry next to him. I went with Cava, Rob with beer. There really are no wrong choices . In the background you can see the big screens that show the top ten speakers and also randomly display comments from any and all sessions. A number of these were very funny out of context.

Earlier Friday I took this picture from my hotel window:

Always you can see Sagrada Familia, I noticed this from the cable car and the castle also. It just rises up out of the sea of lower buildings.

Barcelona was, as predicted, warm and beautiful. Crime was not an issue this year - the police presence was intense and I heard no stories of pickpockets, muggers, or cutpurses this year at all. I discovered the best tapas in the city at Ciudad Condal - which doesn't have its name on a sign so you need to know the address, 18 Las Ramblas. Three of us arrived here - it doesn't take reservations - and fought our way inside through the crowd to reach the maitre-d', who asks "inside, outside, or at the bar?" and then told us it would be 30 minutes for our inside table. The next step is you go to the bar, ask for "tres cervesas por favor" and then point at something from the dozens of plates of gorgeous tapas and montaditos (thingies on toast) and say "tres". Presto - three beers and three (in our case) smoked salmon on toast and you go stand on the sidewalk with the rest of the city. Heaven. The beer was good, the salmon divine, and it didn't even feel like waiting. In no time we had our inside table and then the fun begins. Not a false note - and we gave them lots of opportunities because we ordered a lot of plates. Highly recommended, and actually cost less than some other dinners we had here even though we could barely move by the time we'd finished eating it all.

Will I be back? Well I guess it will be a while till Tech Ed brings me back - we move to Berlin for next year. So I'll have to bring myself back, because I'm really going to miss coming here otherwise.

Tech Ed draws to a close and the website of videos gets updated. This is a general-access-no-login-required highlights site. The mechanism for extracting individual links seems broken, so I'll show you what to click on:

Thursdays wrapup includes footage of the Norway country party (North American speakers typically pick a country to visit for country drinks, and my gang chose Norway) and the Speaker Idol finals (I was recruited as a last minute replacement judge for the finals only.) Speaker Idol impresses me every year because it shows all of us (speakers, track chairs, etc) people who are really good but have not spoken at Tech Ed before. How good? I have a session in the top ten this year, and one of the very few people who is outscoring me is last year's Speaker Idol winner, Jeff Wharton.

The afore-mentioned session in the top ten is here, the full video. Doesn't seem to be downloadable, so set aside 80 minutes and learn about shared_ptr and lambdas. The abstract is inaccurate - I didn't do anything on STL/CLR or marshalling - that was last year. The attendees didn't seem to mind that I tossed out half my planned talk and replaced it with content that had been announced at the PDC .

There are 63 videos all told (though 5 are from last year) and they range from a few minutes long to, well, 80 minutes. See what you missed, and maybe see you next year!

Just in time for my Tech Ed Day 4 talk, we have the long awaited arrival of the Vista Bridge Samples Library, version 1.3, on the MSDN Code Gallery:

Here you can download the latest version, join discussions, and report issues including native APIs you wish were wrapped. Remember, this is a sample library, not a product, so don't expect the kind of support, internationalization, or full coverage a product would have. Do expect useful code for reading (if you care about how to do interop well) or just using (if you want to light up your application with Vista features without knowing about interop.)

Enjoy! I've been waiting a really long time for this!
