Message from the CTO

Sunk costs

There's a concept in economic theory that's of great importance in software development because it comes up all the time: sunk costs. In fact it's fascinating in its own right because it says more about human reactions and motivations than about economic theory.

Imagine the following situation: you've been running a software development project for 6 months and, for whatever reasons -- could be a competitor has come out with something similar, could be that the implementation is running into difficulties -- you're wondering whether to continue the project given the amount of effort and resources -- that is, money -- you've already put into it.

Sneak Peek: What will ASPxCaptcha do for me?

In the last issue of DXPress, Mehul gave us a preview of one of the new controls we can expect in the version 10.1 release of the ASP.NET range of DevExpress controls. ASPxCaptcha was a big hit with our readers, but you felt it could be made better still.

Mehul and the team took on board your comments and critique and they’re happy to say that ASPxCaptcha will support audio.

Take a look at Mehul’s blog to find out more about the research that the team carried out to create the latest addition to the ASP.NET control set.

Is The Doctor's TARDIS advanced XPO technology?

Gary has been experimenting with the geo-tagging capabilities offered by social networking sites, and has plotted his tracks throughout Europe for the past 2 weeks. Taking data incorporating Time as well as Latitude and Longitude, Gary has come up with his very own TARDIS.

Are you intrigued by the geo-coding opportunities that social media sites are offering? Maybe you are working on an internal app for your marketing department to help them to track where their influential posters are, or perhaps your sales team want some real-time data on who is buying and talking about your products.

This mapping application could jumpstart a few cool ideas for you to experiment with. Take a look and see what ideas you can come up with to exploit the possibilities.

String manipulation with CodeRush

Popping the hood of CodeRush and having a good look at the less-than-obvious features can uncover some useful, and often overlooked, features of the Visual Studio add-in.

One of the not-so-well-known features of CodeRush is its ability to split strings and introduce format items.

Check out this collection of Mark's favourite string manipulation features, and why not shine the headlights on your favorite hidden CodeRush gems in the comments too.

Adding spice to a restaurant management system

The Aakash Restaurant has been described by some as "the largest Indian restaurant in the world".

This restaurant juggles a seating capacity of 700 across three function rooms, along with buffet, takeaway and delivery services. Devising a management system that could handle scheduling, function tracking, task management and food orders, all with an intuitive design was no small task.

Software Surgeons, Inc turned to the DevExpress Winforms controls, which allowed developer, Abaid-ur-Rehman Zulfi, to create an “elegant and efficient software solution” to meet his customer’s exacting needs.

DevExpress Community Bloggers: Getting started with DevExpress

Often the largest part of the battle with starting new personal projects or trying new software is motivating yourself to attack the initial learning curve.

Rory has been developing CodeRush plug-ins for some time, but recognized that the initial learning curve could be made less steep by outlining a few of the basics. He’s written a blog post that he hopes will make it easier for others to add to the DXCore Community Plug-ins site.

Nate Woolls is a DX Squad member working primarily with the VCL controls. Recently though, he’s been expanding his horizons. After some research on the DevExpress Channel, Nate started work on an XAF application using embedded Firebird as his database backend.

Check out our community posts and don’t forget to submit yours to us via the DevExpress Facebook page.
