I've put up a couple of quick pages on Microsoft's Reactive Extensions (Rx) and Paul Betts' ReactiveUI, two libraries that are generating a lot of interest in the .NET world.
Michael Dettmer has posted some information on the CodeCharge web development tool, which he points out has a lot of features that make it similar to Clarion and WinDev. Generated code can be in ASP.NET (C#), ASP, PHP, Java Servlets, JSP, ColdFusion or Perl.
While looking at ways to manage database changes that happen as a result of application upgrades, Dave Harms comes across SQL Server's snapshot capabilities. There are some issues to be aware of, but if you need to roll back a database change, snapshots can help you do it in a hurry.
Our focus at DevRoadmaps is on two RAD tools, Clarion and WinDev. But there are lots of RAD tools out there, and we're always happy to learn more. After a question from a reader about CodeCharge, we've gone ahead and created a new page listing the available RAD tools. There are just a few entries - help us add more!

Back in January there was a newsgroup discussion about whether WHERE IN or WHERE EXISTS is a better choice when using a subquery. And that brings up a few other questions, like the role of the cache in testing and the danger of using NOT in WHERE clauses.
Developers who use RAD tools like Clarion and WinDev do so because they believe those tools offer a very real advantage over traditional hand-coder development tools. But are those advantages as great as they seem? David Harms looks at when and why RAD is a help and a hindrance.
We've set up a page for third party SQL database admin tools. Products currently listed include Navicat, SQLMaestro, EMS SQL Management Studio and SQL Delta. We're looking for more recommendations!
DevRoadmaps contains a growing number of pages for MS SQL users. These include: a links page; notes on SQL Server 2012, SQL Server admin tools, how to /wiki/spaces/other/pages/429783, and the tuning advisor,
