List of online real estate solutions

I recently was involved with a extensive survey of online solutions for my employer, a real estate brokerage.  Some were open source, some commercial, some inexpensive and some expensive.  Basically, any full solution that might have worked was added to the list.  Some of these are aimed only at real estate agents (as opposed to a brokerage), but others definitely scale up to brokerages.  (I say full solutions, so you won’t see anything on the list like Onboard Informatics or Altos Research.)

I just wanted to list all of them here for posterity and to help anyone else looking for a real estate solution.

On Being Disrupted

This is a tough post to write.  I’m at the tail end of an evaluation process for my company that ended up with us deciding to go with a third party vendor for software which powers key area of our business.  It is augmentation rather than replacement, but still.

It was hard for me, because this particular key functionality was previously provided by custom software that I helped build over years.

I like to build things!  Like most other software developers, I get excited about building stuff.  One of the unmentioned frustrations of many software developers is building something and then seeing it shelved.

However, it was clear from the survey of solutions that there were three choices:

  1. buy something off the shelf
  2. get better as software developers and really, really accelerate our development
  3. have the business be negatively affected by this piece of software

Now, #3 is obviously not a good solution.  #2 is a great solution, but is hard to put into practice, especially in a short time frame with a large code base (though we are trying to use some of the agile methodologies to make our software development more productive).

#1 it is.

Was this a wise choice?  Talk to me at the end of the implementation, but I am hopeful.  We did take several steps to protect ourself (after all outsourcing core business functionality can be deadly), including:

  • a long, laborious evaluation
  • engagement with multiple vendors, and
  • building a set of criteria to help us determine if this outsourcing is meeting our needs

One thing that helped me take this decision a little less personally is to redefine in my mind the value of software to the company.  It’s not the particular implementation of the software that provides the value.

Unlike a software company, my company doesn’t exist to write software (see Five Worlds for more on different types of sofware development).  Instead, software exists to serve the company.  Having something off the shelf provides the similar functionality for much cheaper.  It also allows me and other members of the software team to write software that is unique.

Having been a contractor and having worked for a startup and consultancy, I’m used to being the disruptor.  In this scenario, I was the disrupted (ht, David Skinner).  It’s a humbling place to be, even if I wasn’t disrupted out of a job.

Building A Site With Google Sites

I recently built out a site for a local tax firm, Cahill, O’Kelly and Associates using Google Sites.  I’ve already talked a bit about using Google Sites for your web presence, but I wanted to share a bit more about my experience.

The reasons I chose Google Sites over something more flexible was pretty much based on what I determined was best for the client.

  • the client is not super technical and was wary of a website
  • I wanted the client to be able to update the site so they wouldn’t have to pay me to
  • they were not super picky about design of the site, so were willing to pick from a template for look and feel
  • site was small and functionality desired was limited (brochureware)

All of these added up to doing something that was quick, cheap, low risk, and easy.  If any of these decision points had been different, then Google Sites would have become a less attractive choice.

Good things about Google sites

  • easy to get going
  • easy to integrate with all of googles other services (analytics, webmaster tools, google forms, etc)
  • lots of templates to choose from
  • hosting is free

Things that suck about Google sites

  • the footer links are out of your control
  • some of the templates require photoshop knowledge to customize (background images)
  • no easy way to roll back changes to your site
  • some of the admin UI is clunky
  • scrolling around the look and feel customization page was difficult

Tips for developing on Google Sites

  • make sure your customer fits the profile mentioned above
  • educate your client on the limitations
  • make backup copies of your sites before you do big look and feel changes.  That way you can manually view the differences and roll back if needed
  • get to know google forms, as that is the only way to do interactive forms that I found
  • be prepared to spend some time tweaking the layout
  • be prepared to do some training on how to edit the site

All in all, Google Sites is a great solution for a certain type of client.  Consider adding it to your toolbox if you do site development.

Own your social media–install Storytlr

I guess I’m just not very trusting, because I like to have copies of my data.  I host my own blog, rather than use blogger or  I host my own email (or at least one of my two main accounts).  I prefer to document interesting things on my blog, rather than a site like Quora or Stack Overflow (though I do have an account on the latter).  Heck, even though I use an open ID provider, my own domain is the master, and I just delegate to

So, since I recently have been putting a bit more effort into my social media presence (you can find me on twitter here), I looked around to find a backup solution.  I did find one–Storytlr–via this article on backing up your twitter feed.  It apparently used to be a hosted service, but now is open source–code here, install instructions here.  (There’s at least one for pay service too, but then, you don’t really own your data, plus I’m cheap.)

It was pretty trivial to install.  I ran into this issue with Storytlr not recognizing that PDO was installed, but the fix (hacking the install script) worked, and I didn’t run into the Zend error also in that bug post.

I also ran into an issue where I chose an admin password of less than six characters on install.  Storytlr was happy to let me do that, but then wouldn’t let me enter the exact same password when I was logging in for the first time.  To fix this, I had to update the password column in the users table with a new MD5 string, created using this tool.

So, what does Storytlr actually give me?

  • Access to my data: I set up feeds to be polled regularly (requires access to cron) and can export them to CSV whenever I want.  And I keep them as long as I want to.
  • One single point of view of all my social content.
  • Really easy way to add more feeds if I join a new social network.  Here are the sites/networks Storytlr supports right now.

The issues I ran into are:

  • Technical issues, resolved as documented above.
  • No support for facebook.  (Well, there’s this experimental support, announced here, but nothing that is part of the project.)  This is big, given how bad Facebook is with respect to privacy.  I am not sure what my next steps are here.
  • Not wanting others to have access to my lifestream.  This was easily fixed with a Auth directive.

If you are depending on social media sites, have some technical chops, a server to host it on, and want to ensure a historical archive, you should look at Storytlr.

Writing a munin plugin

Recently, we’ve run into some stability issues with our main web application.  It’s a small company, so even though I’m definitely not the ops guy, everyone is pitching in with ideas and suggestions.  One thing that the ops guy did install that has been super useful is munin.  This graphing software lets you monitor, over time, many different aspects of your web application and/or servers.  It has been invaluable in letting us know what the effects of the various changes we’ve made have been.

Questions that munin helps you answer can pretty impressive.  For example, does doubling the amount of memory available to your webapp container help stability?  How can you know unless you’re measuring stability?  What happens if you prohibit certain bots from visiting your website?  When during the day or week is your server running hottest?

We have a watchdog that monitors our main application server, and if it is not responsive, restarts it.  The watchdog also records when the restart occurred.  I decided, as a fun project, to write a plugin for munin that would graph the number of restarts per day, as a high level ‘are we more stable yet’ graph.

Writing a plugin was trivial–it’s a shell script that follows certain output formatting. All I really needed was this HOWTO and this explanation of the types of data sources, though the FAQ is, as per usual, worth a scan.

Munin is by no means perfect (my dream feature would be the ability to annotate graphs at a certain moment in time; ‘this is when we released version 2.1’), but it is a huge hammer in the IT toolbox for understanding current and historic behavior of your application.

Gratitude List

Every so often, I just need to stop and say thanks.

Thanks for my family and parents, providing all kinds of education when they raised me.

Thanks to my wife, for being patient and loving, even when I’m not my best.

Thanks to my past and current clients, colleagues and employers, for giving me amazing opportunities, challenging me and trusting me.

Thanks to the vast number of people who contribute to making the internet a fantastic place (this is a software blog, after all).  Whether you create content or build plumbing, the internet is richer for your contribution (even the guy behind lolcats, but especially stuff like this and this).

Every so often, I get wrapped up in some small drama, but nothing knocks me back on my heels and makes me say ‘Damn, I’m lucky’ like making a gratitude list, even one like this which is incomplete.

Say thanks–it feels good!

Useful Tools: StatsMix makes it easy to build a dashboard

I haven’t been to a BDNT lately, but still get their email announcements.  In August, all the 2010 TechStars folks presented, and were listed in the email.  I took a look at each company, and signed up when the company seemed to be doing something cool.  I always want to capture my preferred username, mooreds!

One that was very interesting to me was StatsMix; I signed up for their beta.  On Nov 1, I got invited to sign up.  Wahoo!

Statsmix lets users build custom dashboards.  I am developing an interest in web analytics (aside: if you are interested in this topic, I highly recommended Web Analytics 2.0, by Avinahsh Kaushik).  I’ve been playing with Piwik, an open source analytics toolkit, but Statsmix offers a slicker solution.

They have made it dead simple to create a custom dashboard for users.  They offer integration with, at this time, 29 services (twitter, mailchimp, youtube, Google Analytics, etc).  I could not find an up to date list of integration services outside of their webapplication!  The best I could find was this list from September.  While the integration interface is slick, the data integration is rudimentary.  For example, they will let you monitor the number of rows in a Google Spreadsheet, but nothing more (like rows in different columns, or the value in a particular cell–would be nice to see them integrate with Google Apps Scripting); you can track the number of likes on Facebook, but not the number of comments.

The real power of StatsMix comes from the ease of integration with your own custom stats.  They offer an API which is accessible via REST.  This means that you can push information from your database to a beautiful looking dashboard with shell scripts and a cron job.  Very cool!  It would be nice to see a plugin for Magento or other ecommerce vendors; I recently had a client, The Game Frame, that would have been a great fit for this type of dashboard, since it aggregates beyond what the ecommerce software provides.

Other cool features:

  • The whole UI is beautiful and farily intuitive.
  • The dashboard supports custom date ranges.
  • They will send you an email of stats every day, and apparently have some kind of limited version you can pass onto clients.  I didn’t play with the email feature at all, though it is extremely useful.

However, all is not perfect.  Some issues with StatsMix include:

  • As mentioned above, the integration with third party services leaves something to be desired.  What they offer is a nice start, but it’d be great to see them create some kind of marketplace where developers could build solutions.  For example, the twitter widget only tracks the number of followers.  From the TWitter API, it appears to be pretty easy to track the number of mentions, which could be a useful metric.
  • It wasn’t clear how to share a dashboard, though that may be an upcoming feature.
  • The terms of use are, as always, pretty punishing.
  • Once you develop a number of custom metrics, you are tied to their platform.  That wouldn’t be so bad, except…
  • They are planning to charge for the service, but give no insight into what to expect.  There is a tab called ‘Billing’ but all it says is: “During our beta, StatsMix is free to use. After the beta, you’ll be able to manage your billing preferences on this page.”  If I was considering using this as part of my business, I would want much more insight into possible costs before I committed much time to custom metric buildouts.  I’m fine with them making money, just want more insight into this key aspect of their web app.

All in all, it is well worth a try.  If you to, let me know by posting a comment.  I have 5 invites to give out.


So, the abstraction layer provided by GWT just leaked–well, more of a flood than a leak.

I am working on a site that is pulling in an html fragment which included some javascript code via an XML HttpRequest.  This new code will make paging the results of a search quicker, hopefully leading to happier users.  For reasons too obscure to go into, I was creating a variable named ‘r1’ which I was then adding to the DOM.  The name was completely arbitrary, and was due to laziness (hey, why type 3 characters when you can type 2?).

Fast forward to today, when we’re getting ready to launch the update.  Occasionally, but not often, code that GWT was executing was throwing an exception.  One of the other developers found it because some functionality was disabled.  Here’s what that exception looked like:

exception: (NS_ERROR_XPC_CANT_CONVERT_WN_TO_FUN): Cannot convert WrappedNative to function
QueryInterface: function QueryInterface() {
[native code]
result: 2153185293
filename: http://stageserver/gwt/2B17113CD349EDFD95DC846F38AB0857.cache.html
lineNumber: 4268
columnNumber: 0
inner: null
data: null
initialize: function initialize() {
[native code]

Now, usually, the first thing I do when I see an exception is to recompile the GWT with -style DETAILED instead of -style OBF and see where the error occurs.  However, when I did that, I didn’t see the error message any more.

OK, I added more debugging.  If I added a certain number of alert statements, the error message was nowhere to be found.  OK, go back to the previous code.  Try different pages, different browsers.  Sometimes the exception reared its head, other times it didn’t.  It appeared on some browsers and not others. Sprinkled alerts throughout the code, found the exact line where the exception was being thrown.  All that line did was create a click listener.

Nothing really clear on google; however, this post was useful in pointing to the error message being a collision between a function name and a DOM element.  Searching the GWT google group was not helpful.   I tried using the Firebug debugger, but on obfuscated source, it was not helpful to me.

These kind of bugs make me want to tear out my hair.  Hardly reproducible bugs are no fun. However, I finally found the issue (if I hadn’t, I’d still be working and wouldn’t be posting, that’s for sure).

How I finally solved it:  I was getting a line number.  I finally edited the generated GWT .cache.html file and added some newlines.  This would let me find out exactly which function was really causing the issue.

And, lo and behold, the problematic function was named ‘r1’.

Changing the name of the DOM element fixed this issue. Beware short named javascript DOM elements when working with GWT.

Hope this helps you.

Blogger adds support for pages

I’m a big believer in simple websites that users can maintain–I wrote about how to set one up in less than two hours.  Snarky comments from Ralph aside, it’s a great way to get onto the web and add that much more credibility to any business you’re doing.

Blogger and are the two big options for easy, free web sites.  Blogger gives you more freedom in most ways, but until recently, came with a big downside–you couldn’t create standalone pages (for contact info, ‘about us’, etc)–everything had to be a post.  That’s changed: blogger now lets you create up to 10 stand alone pages.


My Firefox plugins

I recently moved to a new computer, and have been rebuilding my desktop environment.  I just wanted to list my Firefox plugins for future reference.

  • The Web Developer Toolbar lets you view css, disable javascript, resize your browser precisely, outline block elements and so much more.
  • Colorzilla is invaluable for a developer like me to copy a color palate correctly.
  • S3Fox lets you manage Amazon S3 buckets and their content.
  • Firebug lets you examine web pages in detail, including network operations/
  • YSlow is an add on for Firebug that evaluates site performance based on a variety of metrics
  • Some kind of whois tool–sometimes you need to know who registered that domain name

These are my drop dead extensions for typical web development work.  What am I missing?  Do you have any to recommend?
