Hideho everybody.  Two years after getting the notion to do it, I have finally completed the move of my blog to my own server.  The main reasons is to make me the captain of the blog’s destiny, as opposed to WordPress.  (Non-poetic version: I want to manage my own plugins, themes, and general look for the site — particularly important as my business expands and I might use this for something other than just writing about BCC.)

Process to move a blog from WordPress.com to your own server:

1)  Register domain name

2)  Go to WordPress.com and set your blog’s domain as the one you’ve just registered.  This will cost you $10 a year.

3)  Wait several months while Google gradually gets the notion that yourblog.wordpress.com is really www.yourdomain.com (WordPress will 301 redirect to your new domain IF AND ONLY IF you continue paying them the $10 a year — its a steal, do it).

4)  At your hosting provider of choice, install the WordPress software.  You’ll probably want to configure it under a test subdomain for the moment (I used a domain I keep lying around for just such an occasion).

5)  From WordPress.com, export a dump of all your posts & etc.

6)  Import the dump into your self-hosted blog.  If your blog export was over 2 MB (mine weighed in at 2.1), you can have the import succeed by finding your php.ini file and changing the max_upload_size setting line — it should read “max_upload_size = 10MB;”

7)  Test blog, see that most stuff continues to work.

8)  Go to your domain registrar and change the DNS entries for your domain from ns1.wordpress.com, etc, to the DNS entries for your hosting provider.  Wait a few minutes.

9)  Turn on Akismet for your new blog or you’ll be spam city before you know it.  I got 50 lovely comments welcoming me to my new digs within the first 15 minutes.  They all seemed to be by people who work in the pharmaceutical industry.

And, of course, you can play around with your settings, themes, plugins, and etc.  I’ve gone ahead and used the Leviathan theme (customized very mildly with a custom title image — 5 minutes in Paint.NET, will probably replace it with a real image done by my art guy later) and installed a plugin to finally allow me to do some decent syntax highlighting here.  Hopefully that will induce me to post code more often.

Tell me if you notice anything greviously wrong about the blog!

Nice little milestone: Bingo Card Creator just crossed the 100th copy sold in February, for the first time.  The previous record was 93 back in October.

It is also fast approaching a much more consequential milestone, but more on that later.

For the last month I’ve been testing a version of Bingo Card Creator compiled with Excelsior JET versus the standard Java one.  Half of all Windows downloaders have gotten one, half got the other.  I then have tallied when they confirm an installation (i.e. access my website through the application — for example by checking for updates or looking at the purchase page) and purchase the software.  

This is accomplished via a really simple expedient — Bingo Card Creator has a properties file in it, which contains all the strings for the interface like you would expect.  It also contains strings for the version number and site the trial was downloaded from, which I repurposed for the purpose of this split test (since I only track bingocardcreator.com versus “all the download sites” at present anyhow).  

So if you click “Purchase now” from version 2.51 of the Java version of the program after getting hit with the print quota limit, you end up accessing 

http://www.bingocardcreator.com/purchasing.htm?source=trial&version=2.51&site=bingocardcreator&button=printquota

At which point Google Analytics springs into action, uses some very simple logic to parse the query string, and cookies you up with that information.  If you purchase within the next 30 days, the cookie is passed in when you hit the order acknowledgement page and scored as a conversion.  There is a custom segment in Google Analytics devoted to both the JET-compiled and native versions of BCC 2.51.

Anyhow: in the last 30 days I have had 118 sales of Bingo Card Creator.  (Wow, that number shocks me.)  Google Analytics has racked up 116 conversions, meaning they caught the access of the confirmation page on almost all transactions.  Of these 116 conversions, 75 of them were cookied up with a cookie indicating they were positively part of this split test.  (You could easily have participated without getting cookied — for example, if you decided to buy the software and then opened up a browser and Googled [Bingo Card Creator], I would have no way of knowing which executable you had downloaded.)

Of the 75 purchases, 44 were for the JET version and 31 were for the native Java compiled version.  So what’s that mean?  OK, back to Stats 102: if we assume hypothetically that it doesn’t matter which version you were using, we would expect that 50% of the total number of conversions would turn out each way.  However, just like flipping a coin twice doesn’t automatically mean you get one head and one tail, it won’t necessarily be exactly 37.5 sales of each version.  (One would hope not, right?  I’d hate to support the half-and-half.)  

The probability of each possible outcome on the 0 purchases for JET through 75 purchases through JET continuum is given by the binomial distribution.  There is this notion of cumulative probability — given the assumption of 50/50 fairness between the two versions, the probability that any particular result is like to be random is equal to the sum of the probability of that result and all results less extreme than it.  

Plugging and chugging with a binomial probability calculator, we arrive at the result that, if the versions were fair, in only 8% of all samples of 75 sales would we find 44 or more sales for JET.  Accordingly, we conclude that JET is helping sales, by some amount which the binomial probability test is not quite sensitive enough to determine.

Which is good enough for me.  One niggle: I discovered that for reasons beyond my ken, the JET version cannot save to the program directory on Vista, whereas the Java version can.  I probably should have listened to the advice a year and change ago when people said I should revisit the choice of home directories.  (Vista prevents programs from writing to subdirectories of Program Files to prevent bad behavior.  However, it emulates writing to Program Files to avoid breaking legacy software, and that emulation is sufficient for BCC Java but apparently not good enough for BCC JET).  Ah, we live and we learn.  

After I patch that little issue, the JET compiled version of BCC is going to become the default version for all Windows users, and I will keep the Java version around only for support purposes, and to upgrade folks who already have one installed.

Much thanks to Dmitry at Excelsior, who donated a copy of JET to make this experiment possible.

Well, after a few hours of work I have revamped the way BCC presents its public stats.  You can now see everything from one single, easy location:  http://www.bingocardcreator.com/stats

Part of what I’ve been working on recently is taxes for 2008.  This required actually paging through and entering my expenses (oh, did I mention it tracks expenses now?), which is going to result in a bit of an earnings restatement for 2008.  I think I have everything but one stray freelancing invoice accounted for now.

Sales for 2008 (less returns): $21,116.65

Expenses for 2008 (excludes taxes): $11,782.62

Profit: $9334

You can see the detailed breakdown here — the big green slice is profit (~45% — a bit lower than I expected).  If you just want to see the relative expense breakdown that is available, too.  Unsurpisingly, my number one cost is advertising — the overwhelming majority of it is Google AdWords but I also paid much smaller amounts Microsoft, Stumbleupon, and a few directories. 

Since I’m using this to generate taxes for my business I included some things for my non-BCC projects which I intend to productize eventually but haven’t gotten around to yet.  Incidentally, expenses before 2008 aren’t totally entered yet, take that data with a grain of salt.  I don’t have easy access to all my old 2006/2007 credit card statements, and don’t even get me started about Paypal.

The results from the shopping cart redesign are in.

Short version: Conversions increased by 94%.  I’m pretty flabbergasted.

… I will learn to not, under any circumstances, commit any code to the trunk which is not ready for immediate deployment.

Because when I do, I inevitably do “just a quick deploy to fix up that unrelated mistake” and then, boom, the lightbox on the front page silently fails for three days.

SIGH.

On the plus side, I once again have experimental confirmation that functional lightboxes beat the stuffing out of direct links to images!
