General Development In DotNet

" When the browser makes a request for a static image and sends cookies together with the request, the server doesn't have any use for those cookies. So they only create network traffic for no good reason. You should make sure static components are requested with cookie-free requests. Create a subdomain and host all your static components there. "

"This page provides a comparison of key capabilities between SQL Server 2008 Enterprise, Standard, Workgroup, Web and Express editions."

" Django may be built for the Web, but CouchDB is built of the Web. I've never seen software that so completely embraces the philosophies behind HTTP. CouchDB makes Django look old-school in the same way that Django makes ASP look outdated. -Jacob Kaplan-Moss, Django developer CouchDB's design borrows heavily from web architecture and the concepts of resources, methods, and representations. It augments this with powerful ways to query, map, combine, and filter your data. Add fault tolerance, extreme scalability, and incremental replication, and CouchDB defines a sweet spot for document databases. "

"jQuery 1.6 is now live and available for consumption! We're quite proud of this release, it includes a major rewrite of the Attribute module and a number of performance improvements."

"Evently is a jQuery plugin designed to take the repetition out of writing event-based applications. This page collects documentation and tutorials for using Evently, both inside and outside of CouchApps."

" Reflection, like it or not, it is inevitable that eventually you will have to write some code that involves looking at the members of a type at runtime (rather than at compile time). Maybe you are trying to write utility validation / serialization / ORM code, or maybe the interesting property / method is specified at runtime in a configuration file or from the database. Whatever the cause, it is likely that at some point you've written code involving GetType() - something like:"

"WAI-ARIA, the Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies. Currently certain functionality used in Web sites is not available to some users with disabilities, especially people who rely on screen readers and people who cannot use a mouse. WAI-ARIA addresses these accessibility challenges, for example, by defining new ways for functionality to be provided to assistive technology. With WAI-ARIA, developers can make advanced Web applications accessible and usable to people with disabilities."

" Robert Myers has more than 25 years of professional experience on software development teams, having consulted for leading companies in aerospace, government, medical, software, and financial sectors. He has trained and coached teams in XP and Scrum since 1999. Rob now continues these activities as Agile Coach at Salesforce.com. He blogs occasionally at PowersOfTwo.agileinstitute.com. "

Greg talks about how we've forced our customers to work with data when they're naturally behavior-centric.

"UPDATE: I've updated the msysgit installation screens so they are more current. Git-1.7.2.3 is the latest one as of this update. The subsequent screens show Git-1.6.3. I assure you that all of the commands in the first three parts of this series will work on 1.6.3."

Awesome!

"As part of my talk at the 2009 US PASS Summit here in Seattle called Inside SQL Server Wait Types, I'm creating this blog post as a reference point that can be used to find out information about wait types in SQL Server 2005 and 2008. My hope is that if you have a question about a wait type you encounter with SQL Server 2005, 2008, or beyond, you will use this blog post as the starting point. This blog post should also be used as an enhancement to what you can find at the following SQL Server Books Online topic:"

"To say I like SP_WhoIsActive is an understatement. This is probably the most useful and effective stored procedure I've ever encountered for activity monitoring. The purpose of the SP_WhoIsActive stored procedure is to give DBAs and developers as much performance and workload data about SQL Server's internal workings as possible, while retaining both flexibility and security. It was written by Boston-area consultant and writer Adam Machanic, who is also a long-time SQL Server MVP, a founder of SQLBlog.com, and one of the most elite individuals who are qualified to teach the Microsoft Certified Master classes."

"There can be a great difference in the performance of a particular routine in a test database, and in a fully loaded production system. When you hit performance problems in a database under load, and there is excessive locking and blocking, how can you determine exactly where the problems lie, in order to fix them? Read on..."

"Lock escalation is a event which occurs when SQL Server decides to upgrade a lock at a lower level hierarchy to a lock to a table level lock., In other words, when a particular query obtains a large number of row level locks/ page level locks, SQL Server decides that instead of creating and granting number of row level/page level locks, it is effective to grant a single table level lock. Or to be precise,"

"Recently I encountered a case when I knew much more about the data than the optimizer. Originally the performance was horrible, this is why I had to have a look at the query in the first place. When I was able to share my knowledge with the optimizer, it produced a better plan, and the query ran dramatically faster."
