Marc Andreessen's Eleven lessons

Marc's disabled comments on his (excellent) blog. Marc, I see at least two issues with that: First, a lot of times I only have a sentence or two to add to a post and it hardly seems worthwhile to create a brand new article on my own blog. Second, if anything it's even easier to spam trackbacks than it is comments! Although I don't have enough readers to bother about any spam-blocking besides the Blogger default captcha, surely you could come up with some mechanism to ensure a human is the one entering the comment. And isn't it a shame to restrict comments only to those who have their own websites?

Evaluating Javascript in an NUnit test

Adam Esterline posted his solution to javascript testing. He uses WatiN to run tests, which I wasn't excited about; I was hoping for a way to test where I didn't have to install any more software anywhere. Here's the solution I came up with:

static object Evaluator(string code )
{

ICodeCompiler compiler;

compiler = new JScriptCodeProvider().CreateCompiler();
CompilerParameters parameters;

parameters = new CompilerParameters();
parameters.GenerateInMemory = true;
parameters.GenerateExecutable = true;

parameters.ReferencedAssemblies.Add(Assembly.GetExecutingAssembly().Location);

CompilerResults results;

results = compiler.CompileAssemblyFromSource(parameters, code);
if (results.Errors.Count > 0)
     throw new Exception(results.Errors[0 ].ErrorText);

Assembly assembly = results.CompiledAssembly;

MethodInfo entryPoint = assembly.EntryPoint;

return entryPoint.Invoke(null, new object[] { null } );

}

[Test]
public void EvaluatorTest()
{
  Evaluator( "Context.Current.Data = \"Craig\"" );
  Assert.AreEqual( "Craig", Context.Current.Data );
}

This seems elegant and able to handle a lot of things like side effects. Unfortunately I've been back on the server side for the most part and haven't really tried to put this code through its paces.

Lawn sign in the Forbidden City

Mark Hurst's great This Is Broken website gives examples of bad user interfaces, both on the net and in the meat world. You can't argue with most of the entries, but I love this sign. The grass is quietly asking us, "Please Do Not Disturb Me". The extra "Me" on the sign gives a really dreamy, tranquil, and above all Chinese feel to the landscape; much better than the harsh "DO NOT DISTURB" or "KEEP OFF THE GRASS" signs we Americans are used to. (I'm posting this here since you have to be a registered user to add comments to the site).

Frames Per Second in birds

I had occasion to visit Hardin Ridge yesterday for the International Migratory Bird Day celebrations. They had several stations, and it was fun for the kids, but one thing I thought was interesting was during a presentation on birds of prey. They displayed a peregrine falcon and talked about its remarkable vision; here's what Steiner has to say about it:

They are equipped with full-color vision and with eyes specially adapted to permit rapid adjustment of focus while moving at speed, and from four to eight times the resolving power of the human eye. Hovering may be compared to looking into a field from a car moving at twenty miles an hour or from one which comes to a standstill every few yards. It would be possible for a human being to see an individual rabbit or large game bird at a range of 600-700-yards; a bird of prey, with about four times the resolving power of the human eye, should therefore be able to see it at a range of nearly two miles.

What particularly caught my attention, though, was when they said that the peregrine can perceive significantly more events per second than humans can. I don't know if it's exactly the same concept, but I assume we're talking about frame rate here; they commented that even when cameras have been attached to these birds as they make one of their amazing, 200 miles-per-hour dives onto some unsuspecting pigeon, all humans can see is blur.

Now, the frame rates they mentioned seemed surprisingly low to me they suggested 18-20 events per second for humans and maybe two or three times that amount for the birds. But I suppose it's an example of flicker, and syncing, where if you perceive the wrong couple of frames in a videogame the action seems all wrong, or maybe the afterimage in the eye causes the slowdown.

So I'm not sure where all this is leading, except maybe that a really cool videogame would be Peregrine: The Stoop for a Pigeon. But I suspect there's a lot of basic science to be done before any game can simulate the visual experience of this amazing animal.

Choosing a Kindergarten

It's a funny thing, but I'm pretty used to being marketed to. When I needed to get a gym membership, the gyms that I went to had someone there to give me a tour; show off the machines and the hot tub; in general make me excited about going there. Or when my wife was checking out nursing homes: she had a very similar experience with people who wanted to make her comfortable and get her interested in coming back, offering her cups of coffee and things.

So when we got the letter about coming to a kindergarten open house, that's sort of the thing I expected. I thought the people would be interested in showing us around and getting us excited - like the gym or the nursing home, trying to sell their product to us, sell us their school. I guess the first warning I should have had came straight from the informational packet, though: there was really nothing there except lots of information about "your child" - "your child" should be able to tie his shoes. "Your child" should have lots of time to read with you. "Your child" needs to be independent enough to go potty all alone. Not a word about this big, new, mysterious place he'll be going to.

So I was expecting some more information on the school at the open house. Unfortunately, what they had for us was another informational packet explaining what "your child" had to do in order to be ready for kindergarten. And who was running the open house? One kindergarten teacher. The school has two, but the other was busy - and I understand she just lost a family member, so that was okay - and the principal apparently had decided that some interviews he had to do were more important than meeting the new parents. I disagree.

So it's very clear when you leave the private sector, even for a heavily regulated industry like nursing homes. We obviously had some amount of choice over our kindergarten, but once we made the important step of purchasing a home, we were pretty much stuck with this one, and I think that the information we got reflected that. I'm not even saying it's intentional - simply that no one's ever thought twice about having to sell their school, because no one has to.

That in a nutshell is the biggest problem with the school system, IMO. It will be interesting to see if this pattern continues or whether some more wholehearted attempts will be made at engaging us.

Precociousness

Hey, dad?
Uh-huh?
How many hours are there in a day?
There are 24 hours in a day, son.
Oh.
So how many hours are there in a night?
I meant, there are 24 hours in a day and night together.
Even in wintertime?
Huh?
In wintertime the nights are longer.
Yes, but the days are shorter too.
Oh.
So there aren't 24 hours in a day in winter?
What?
Well, you just said the days are shorter.
Well, that's true, but...say, why don't you go play with your toy cars for a while?

FastTrack seminar, part 2

Second session at the seminar was on the new features of SQL Server 2005; since I was at the launch party in Indianapolis I didn't feel like there was a whole lot that was really new; but since I'm currently employed at an Oracle shop it was interesting to compare the two. This session was given by George Huey, a Microsoft "Architect Evangelist", whatever that is; but he knew his stuff. The most interesting new feature from my admittedly database-illiterate perspective is the ability to write code in .Net and turn it into stored procedures and code that runs inside the server process. You can also set the code permissions: Safe, Unsafe, or External Access, which I believe means, "hits the file system", but regardless I don't know if anyone actually uses that feature. Another interesting feature is the ability to run "recursive queries", which sounds pretty handy: he gave a demo of calculating the number of levels of management by recurring up the tree until you find the guy with no manager.

A few other features he went over were: Native XML store; Pivots; Top; and Rank; they all seem very nice but I'm not really in a position to judge how useful they would be in my work. I guess we'll see.

The final session was on "Business Intelligence". I didn't have any idea what that might involve, but it turned out to involve reporting. I wasn't aware that you can configure SQL Server to give you a project type of "Report" in Visual Studio fairly easily, and there's also a "Report Viewer" control that you can add in to your own ASP pages. I have to admit that I lost some of this lecture, as the presenter was having some trouble with his computer and the wireless was working nicely - for a change - so I took the time to mess around with some more of the AJAX demos that I was really interested in.

The seminar was held in the Glick Center, where the Indy NDA holds its meetings. It was a good venue to hold the couple of hundred people who showed up. Microsoft sprung for donuts and pizza, and I liked the idea of having a couple of arcade games for people to check out between sessions. I would have traded them for better wireless, though. There were also only power outlets on one end of the room. But there's only one really important highlight: through the door prizes, I am now the proud owner of a Zune :) Welcome to the social! (Hello? Is there anyone else in here?)

FastTrack seminar

I’m blogging today from a Microsoft FastTrack seminar. Perpetual Technologies in Indianapolis is putting this on in some sort of collaboration with Microsoft. It’s a free seminar – and I’m always up for a free seminar – with a keynote and six sessions in three time slots.

The keynote was OK. Steve Thompson from Microsoft gave a roadmap presentation of where they expect enterprise technology to go over the next several years. The majority of audience were DBA’s rather than developers, so they may have had more interest than I did. As important things, Steve brought up Office, Microsoft Server, and mobile applications; and also Microsoft Business Solutions, about which I don’t know much. The goal, I guess, is to get enterprises on the Services Oriented Architecture bandwagon, and also to move towards virtualization as an important technique for scalability. He also discussed voice and VOIP near the end of the presentation, and how our standard voice data paradigm – blinking message lights and busy signals – is really out of date. This is something I’ve known since Interactive Intelligence was trying to get everyone out of that as well; don’t know how that effort is going, but we still have the copper wires at my last couple of jobs.

First session was on the Ajax.Asp.Net control library, which looks pretty cool. It was given by a younger guy from - I think - Crowe Chizek, and he did a creditable job, although I would have happily spent a couple of additional hours learning the subject, given the opportunity. It's interesting that most of the effects it allows you to create are already implemented in Javascript in the application I'm currently working on - a tribute to the skills of the original writers of this app, I think. But, you could certainly write a lot less code to get the same effects using this library. It looks pretty easy to use, although .Net 2.0 is required: one msi to install on your machine, and one zip file with controls and demos. It'll definitely be useful in my own web applications, anyway!

Javascript testing with NUnit

I've been looking around for a good way to test Javascript functions.

There are at least two if not more versions of JSUnit, one here and the other here. But there is one fundamental requirement I have for any unit testing framework, and that is that it has to integrate into an automated build script. For example, suppose you're using CruiseControl. It's got an NUnit step in it; once you write up your tests, it's the matter of a few minutes' configuration to get them running as part of the build, and it's very satisfying to watch the test counts grow as more builds are done. 117 tests run, no failures. 123 tests run, no failures. 135 tests run, no failures.

So if the framework doesn't work with automated builds, it's no good to me. Do they? I'm not sure. Edward Hieatt's version seems primarily to require a browser, although he does provide a JSUnit Server which appears to be designed to work from Ant or Java, but doesn't have any particular support for Nant or ASP.Net that I could find. Jörg Schaible's version is even less able to work in Windows; starting from the download which is only provided in tar.gz format. The documentation states that it can be run from the command line; if so that's easily adaptable to an automated build, but I didn't even take the trouble to download it, suspecting that it wouldn't even run on Windows.

So I was looking around for other alternatives, and I ran across this post. I'm sure that not everything you can write in Javascript can be evaluated by the .Net Javascript evaluator, but when you write a lot of tests you get used to keeping functionality nicely isolated.

I'm not sure what the best way to use this is. My first couple of tests have the Javascript in the ASP.Net codebehind file, where they can be unit tested at test time and Response.Write-n at runtime; but there's a few other possibilities; keeping all the Javascript in a separate file to be read in at test time, and using it as an include at runtime perhaps.

So I have a lot of work to do on this technique. But it seems promising!

Sports and power ranking systems

I've had an interest for a long time in the science of sports team rankings, for various reasons, which was forcibly brought to mind when I was filling out my tournament bracket. I'm always extremely mediocre in such game-picking contests, and when one blogger whom I respect said something similar, I started to think about how rankings could be done for college basketball. I looked a little closer at the Pomeroy Rankings, which seem pretty nice, although if Ken reveals his exact formula for creating them, I couldn't determine it. IMO a ranking system can't be taken seriously if the method that is used isn't known. Take Jeff Sagarin: Everyone always prints his rankings up very seriously, but we don't know what he's doing, so he might as well be making them up and just pretending it's math.

But Ken has something much more valuable on his site than a ranking system: a game database. For the most part, this information is not available in any easy-to-get-at-form, so if you want to create the rankings, you have to get down and do the data entry every year, which is why I've never created any system that lasted more than a year. But now, with Ken's files, maybe something useful could be done.

So I did a little research, thinking that the most effective system probably was going to be some kind of balance between a single-game Pythagorean expectation and strength of the opponent, repeating until the numbers converged. I'm sure I read a paper about that some years ago, but I can't find it now. Instead, I found this, a technique which doesn't take into account the scores at all!

But it's interesting, because it's based on the age-old theory of game commutativity; to wit: my team beat team X and team X beat your team, so my team is better than yours. Yah. It's a principle that's been widely derided for years, and people make hobbies out of finding weird cycles of games proving that Prairie View A&M is really better than Michigan after all. But there's obviously a kernel of truth in it. The paper goes into a lot of detail about setting up the graphs and putting weights on things and, you know, math, but really the principle is pretty simple. It works like this:

For each game that my team wins, it gets partial credit for each win the team it beat has.
For each game that my team loses, it gets partial debit for each loss the team it lost to has.

That's it. The questions are, do you want to go deeper and credit my team for a third or fourth level, and just how much credit do you give for each "indirect win"? The second question is easier for our purposes, because the authors of the paper do a lot more of that math stuff and come up with a simple equation for us:

Let k equal the average number of games played by each team.
The credit is (2k) / ((k^2) - k ).

For a third level, you'd square the credit, etc. But do you want to do the third level? Say the credit is .1, or 10% of a win. For the third level the credit would be .01, which doesn't seem like much, but you're talking quite a few games, too. So I'm going to have to use Ken's game database and do some research on this. Any code I create will be open-source, of course. I won't be able to do anything useful before this year's games start, but next year, watch out!

Generating classes from XML in .Net

The Oracle version of SQL has some nice keywords for returning your data in an XML format. (I suppose the other servers do too, but I've not used that feature.) When I get the XML back, I want to turn the XML into a set of business objects for easy serialization. XSD is the tool for that. Write the XML to a file, run XSD on it to generate a schema, then run XSD /c to generate the C# class file, and you've got a nice class. You can muck around with the XMLElement and XMLAttribute attributes to create nice field names, and 30 seconds to put together a static Get() method that returns a class from the XML.

Except it didn't work. The serializer threw a File Not Found error. When the XMLSerializer class has a new type it needs to serialize, it just generates the code on-the-fly and throws it into a new assembly with a name like olkdzxc.dll, and returns the class from it; but when I called the serializer, it told me that olkdzxc.dll wasn't found. Very mysterious.

Luckily, I remembered Chris Sells' old tool that was made for debugging exactly this problem, XMLSerializerPreCompiler, which lets you see the compiler errors that occur while the code is being serialized, and one of those led me to the problem: When generating the class code for an array of objects, XSD was adding an extra set of brackets in. So instead of having a class member myFoo[], I had a member myFoo[][]. Why did XSD do this? I have a hard time believing it's just a silly bug. I'd love to hear if anyone knows.

Online and offline communities

I wrote earlier about creating online communities around business-to-business applications, with a vague promise to add more, but didn't. What rejuvenated my interest in the topic was going to a lecture and buying a book by one Joseph Myers, who lectures on creating small groups for churches. Churches generally don't like to be impersonal - it kind of misses the point - but there's no real alternative once the congregation grows beyond 100 or so people, so they like to subdivide into smaller groups so everyone has a group they can be comfortable with. What Joe Myers pointed out, as I understood it, is that it's very hard to create this sort of a group from the outside - intimacy generally arises from a group of people who like to be around each other. So, if you are a corporate executive, or a church leader, who is tasked with creating a community, how do you go about it? On the one hand, it's our job to create these communites, on the other, we know that they're not created, they just appear.

So the recommendation, for church leaders at least, is to define more exactly what groups already exist in the church. Church leaders want every small group to provide intimacy, but that's really only one way to relate to a group: the group can be more of a public group, or more of a social group, or just a personal group, and churches can take advantage of knowing how these groups relate to each other to encourage more fellowship in the church.

Is it applicable for online groups? I'm not sure. Here's the issue: at least if you're working with a church congregation, you can call a meeting, bring everyone in, discuss the issues, maybe figure out what the existing groups are and what they're doing. You can't do that online. Maybe the best thing someone tasked with creating an online group can do is simply to monitor the group, or groups, and make sure that the company is willing to go wherever the group takes them. Seems obvious, but is it? Check out Yahoo's handling of Flickr accounts, or Facebook's decision to allow non-college students to join. Or check out a lot of different online forums that die because people thought they were cool at first, but then they never changed again and everyone left for more responsive pastures.

I don't know the answers. But it's an interesting bunch of questions.

Quality of Local Political Blogs: Compare and Contrast

I've been writing various articles for Bloomingpedia in the last month or so, in an effort not so much to improve that site as to understand better the town in which I live. One of the keys to understanding a city, I think, is to gather a lot of different perspectives from a lot of different individuals with a stake in the matter. Take Indianapolis, for example: there are a lot of places you can go to get an impression of how the city is doing. Ruth Holladay; Matt Tully. Taking Down Words; Indy Undercover. You have to gather them all together before you can make a critical analysis of what's really going on; but they're there, that's the important thing.

Or you could read the Indianapolis Star. But I don't have much trust in the Main Stream Media. Their goal never seems to be so much the truth as it is finding someone who disagrees, no matter how foolish or inane that person may be, and unless you already know the subject matter pretty well, you can't tell from the way the article is written which is the inane perspective and which is sensible. So that leads you back to blogs.

Here are four local politicians who have been on my mind lately: Marty Hawk, Dave Rollo, Scott Tibbs, Sophia Travis. How easy is it to get their perspectives on local issues?

Far and away the best online writer in this group is Sophia Travis. If you just looked at the MSM, you wouldn't think much of her except that she's a little flaky (an accordion player with political aspirations? Weird!) But when you read her blog, not only is she talking about the tough political issues, but she's following up on comments people leave; leaving comments on other local blogs; sending in questions to local online chats; really being a part of the conversation about what Monroe County is, and what it should be. It would be great if every politician had an online presence like Sophia's.

Second best is Scott Tibbs. I actually started this post thinking about what I don't like about Scott's blog: there's no real comment area on it, just a link to a bulletin board, which I assume is also run by him, and which you have to register on before you can comment. He says that's to avoid spammers, but obviously a lot of bloggers manage to allow real comments without going to that extreme. But the point is, he writes, and discusses, and allows discussion of his views in some form. So I can't take too much umbrage, especially compared to:

Dave Rollo. He's got a web page; it's a start. The page is very static; the main page has a "last updated" date on it, but there's nothing to find what was there before. There's only a few paragraphs discussing his views, and there's no way to leave public comments, and if he's ever left a comment online I haven't seen it. Start a blog, Dave. He did participate in an online chat recently, and having a web page puts him ahead of:

Marty Hawk. Not much to say here, because I really couldn't find out anything. She gets quoted in the local paper from time to time, and you can go read the minutes of the Monroe Council meetings and find some things she said. But right now, the number 2 hit on Google when you search for her name is the article I wrote on her last week. So we really don't know too much about her at all. It leaves me defining her, rather than having her defining herself. If that's what she wants, then that's fine.

So that's where we are in online local politics in Bloomington. It's a start. But I wish there were a lot more politicians in the conversation.

Bookplates

(Hey, this is my 200th blog post! And it only took me three years!)



One principle of agile development that doesn't get a lot of attention is Sitting Together. The point of the principle is simple: agility requires communication, and there's no faster communication than shouting over your shoulder to the guy behind you! I think it's a bit overblown; communication is hugely important, but with the advent of instant messaging, not only do you know that Dan down the hall is sitting at his desk, but you even know that Mike down in Dallas is, and they're just as likely to respond to your ten-second query as Jennifer two desks away is. The participants have to be in pretty close time zones, though; Suresh in India just isn't gonna respond to your IM no matter how many times you check his status during the working day!



In my new company we sit together, which is something I've never done anywhere else. I've found that one disadvantage is that my desk doesn't have space by half for my programming library, which I like to keep at the office for easier reference. (Okay, so I haven't referred to the Differential Equations textbook since I left the videogame industry. Nevertheless.) So I'm taking over a couple of shelves nearby, but instead of just writing my name in all my books, I thought it would be more fun to make bookplates for them. Here's the design I made:

I'm no graphic designer, but I thought it was OK. If you want to modify it for your own use, feel free; I've made a Word template available for use with the Avery labels that come six to a page; you can get it here, or download the Avery bookplate for the four-a-page labels. Hey, my favorite book site LibraryThing, why don't you provide some of these? I'm sure there are dozens of people who can do better!

Government RSS Feeds

Sophia Travis is a Monroe County Council member - and, remarkably, one who is sophisticated enough to have her own blog. On one post, she asks what information we'd like to see on the Monroe County web pages. I would like to see an RSS feed. Here's why: Government business does not lend itself well to the regular web page format. The people's business does; the most important thing for the web site will always be ways to contact government officials; how to apply for permits; pay parking tickets; vote, etc. But government business consists mostly of a neverending string of public meetings, each one with an agenda beforehand and minutes afterwards. The best way to present a stream of information like that is with a feed. For example, I've already created a feed for the Council meetings using the very nice, if complex, Feed43 service. My feed will do the job, giving me an update through my feed reader whenever a new meeting agenda or minutes are posted, but it's pretty content-free, as the feed can't do much except monitor each row of the table of meetings on the page. But suppose the county tech services people set up an easy way to post updates using TypePad or Blogger - suddenly it's easy for them to update the site and there's a good description of the update in the feed. Then, perhaps, it could be expanded using the same feed, to give information on other public meetings, notice of events the council members are participating in, and any other kind of information that has a time element. I'm thinking this is actually a time saver, at least for that one poor soul whose responsibility it is to go in and edit the HTML table on the page whenever new meeting minutes are available!

What would you like to see on your local government web site?

Change is good

I've accepted a new job with Envisage Technologies, a small software company in Bloomington. I'm excited about it as it's a company with a firm interest in agile principles:

Do ideas by the Gang of Four, Steve McConnell, Martin Fowler, Tom DeMarco and Kent Beck resonate with you? Join an experienced team of developers in an Agile environment...

So I'm no longer working in Indianapolis for the first time in more than ten years - I'm not sure what I'm going to do with all the extra time!

(I've also set up a LinkedIn account as per Guy Kawasaki's suggestion. Drop me a line if you want to connect to me.)

Prius anti-skid props

The problem with having six inches of snow dumped on us is that the hill that leads to our house has a slope that isn't quite a vertical wall, but that's pretty close. So as I was heading home my wife assured me she'd seen the plow go by, and I decided to take the hill, which in good weather would be five minutes, as opposed to going the long way round and taking half an hour.

Up I started, accelerating to about 25 MPH and getting at least 30 or 40 yards before realizing that the plow hadn't been by recently enough to make a difference. It was easily the worst snow I'd ever tackled on the hill before, and it's not fun having to back down that slope, let me tell you. Especially with the literal vertical drop on the side that sends you ten feet straight down before the drop is conveniently stopped by a tree.

But here's what the Prius does, straight from the brochure:

Motor Traction Control (TRC) – TRC uses sensors which automatically apply the brake to any slipping wheel while delivering more power to the wheels with greater traction.
Vehicle Stability Control (VSC)* – VSC senses oversteer (tail slide) and understeer (nose pushing forward), and managing the power delivered to each wheel.

It was a beautiful thing. I kept the accelerator right around 25 and the car took over from there. It never slipped sideways, never fishtailed, and actually applied acceleration to the wheels in bursts of a couple of hundred milliseconds at a time, followed by coasting to grab what little traction it could, and then accelerating again, and I was at the top of the hill as nice as pie. I only felt guilty for not stopping the cars I passed and telling them, "Your car got TRC? Got VSC? Then DON'T try the hill tonight! Just because my car can do it doesn't mean yours can!" What a beautifully engineered vehicle.

WiX installer and Error 2708 (No entries found in the file table)

I had to add different versions of a file to my installer today. Seemed easy enough to do - the files were available in the right places and everything, so I added a version number on to the old file ID, added a new file with the new version number, and called it a day, right?

Not so fast. Compile up the install and run it:

Error 2708: No entries found in the file table.

Say what? Must have been a file system glitch. Open up the MSI with Orca and check the file table; well, yes, it has lots of entries, no trouble there. What's going on here?

Buried deep in the search results for the error code I found this page. The comment from Jane D pointed out that she'd seen this error while having problems with the Duplicate File table rather than the File table - and that jogged my memory. In a separate component I had a CopyFile element that was pointing to my file, and it still had the old file ID reference, now orphaned. Update the reference, recompile, and bingo. Working install.

I see this as a bug in the WiX linker: why did it build the MSI with this unresolved reference? I'll have to post something to the mailing list at some point.

Credibility redux

Y'know, I'm not affiliated with Microsoft at all, although I own some stock and use their products happily. So I'd like to think that when I say something like, this Microsoft employee has credibility, it's because the employee actually has credibility and not because I'm biased or brainwashed towards the Borg.

I've been a loyal subscriber of Dare Obasanjo for at least a couple of years now, and a happy user of RSS Bandit, although I'm now evolving a bit into Google Reader for its mobile capabilities. So when I read his article about changing Wikipedia I didn't think much about it; mildly interesting but not a big deal, and his changes in the TechCrunch entry certainly deserved reverting under the Wikipedia "No experimenting" clause. But Michael Arrington's reaction was out of line:

A Microsoft employee, who took issue with this blog post, vandalized the TechCrunch Wikipedia entry and wrote about it on his blog.

That is a misuse of the word vandalized by any stretch of the imagination. Dare added maybe a couple of sentences with a dry, unemotional tone. He put up an apology in the comments, too, but in two or three comments (which have now disappeared) Arrington repeated the vandalism charge, and he's showing no signs of backing down. IMO, there is a serious credibility gap in repeating an emotionally charged word like that in response to some rather minor issues. I'd never heard of Arrington before, or read TechCrunch. This little flap doesn't make me want to, either. Michael Arrington joins Andrew Orlowski in my credibility book.

B2B 2.0

Chris has left LibraryThing. I don't know him, but apparently he's done some really good work for one of my favorite Web 2.0 plays; a social site based around book collecting.

There are lots of definitions of Web 2.0, but at least one of the principles that seems to define it is "Online Community". Flickr, YouTube, Yahoo! Answers. Online communities have been around since the beginning, of course, at first through mailing lists and NNTP servers, later through applications and, eventually, web sites. When we at Sunstorm were working on a version of Deer Hunter that was going to have a multiplayer mode - we had only the vaguest idea how that might work - I went to a seminar at the Game Developer's Conference on the topic of building online communities. We did a little work towards it; our web site ran some decent forum software, but in 1998 the Deer Hunter target market did not actually overlap with people who spent a lot of time online, which was hampering.

At least we had a good size target market. Combine the lush outdoor scenery of Deer Hunter 3 with a visionary concept of online communication, and we might have had our own version of Second Life on our hands, five years before anyone else. But of course, we didn't have the vision thing. It's still the hardest part of launching a consumer oriented web site. Wal-Mart tried it. Xanga was hip for a while. Not much there there, now.

But what about an online community as part of a B2B play? Not a corporate MySpace, but a self-selecting group made up of users of your product. If your target is geeks you might have a leg up here; Kinook has a nice online forum. Axosoft has forums and bloggers. The forum we put up at Interactive Intelligence seems to be buzzing along nicely. When I was there the customer base was very technical; that may be less so as their customer base has grown. But I think an actual, product-based online community is very workable for a business-to-business company. More later.
