Disclaimer: This may sound like a rant but it isn't meant to be. In the wise words of Raymond Chen this is meant to highlight problems that are harming the productivity of developers and knowledge workers in today's world. No companies or programs will be named because the intent is not to mock or ridicule.
This morning I had to rush into work early instead of going to the gym because of two limitations in the software around us.
So a bunch are working on a document that is due today. Yesterday I wanted to edit the document but found out I could not because the software claimed someone else was currently editing the document. So I opened it in read-only mode, copied out some data, edited it and then sent my changes in an email to the person who was in charge of the document. As if that wasn’t bad enough…
This morning, as I'm driving to the gym for my morning work out, I glance at my phone to see that I've received mail from several co-workers because it I've "locked" the document and no one can make their changes. When I get to work, I find out that I didn’t close the document within the application and this was the reason none of my co-workers could edit it. Wow.
The notion that only one person at a time can edit a document or that if one is viewing a document, it cannot be edited seems archaic in today’s globally networked world. Why is software taking so long to catch up?
While I was driving to the office I noticed another email from one of the services that integrates with ours via a SOAP-based XML Web Service. As part of the design to handle a news scenario we added a new type that was going to be returned by one of our methods (e.g. imagine that there was a GetFruit() method which used to return apples and oranges which now returns apples, oranges and bananas) . This change was crashing the applications that were invoking our service because they weren’t expecting us to return bananas.
However, the insidious thing is that the failure wasn’t because their application was improperly coded to fail if it saw a fruit it didn’t know, it was because the platform they built on was statically typed. Specifically, the Web Services platform automatically converted the XML to objects by looking at our WSDL file (i.e. the interface definition language which stated up front which types are returned by our service) . So this meant that any time new types were added to our service, our WSDL file would be updated and any application invoking our service which was built on a Web services platform that performed such XML<->object mapping and was statically typed would need to be recompiled. Yes, recompiled.
Now, consider how many potentially different applications that could be accessing our service. What are our choices? Come up with GetFruitEx() or GetFruit2() methods so we don’t break old clients? Go over our web server logs and try to track down every application that has accessed our service? Never introduce new types?
It’s sad that as an industry we built a technology on an eXtensible Markup Language (XML) and our first instinct was to make it as inflexible as technology that is two decades old which was never meant to scale to a global network like the World Wide Web.
Software should solve problems, not create new ones which require more technology to fix.
