Share Your Ideas ::: Folder URL Shortener
Have a great idea? Better keep it to yourself. Someone else will snatch it up and do it if you tell! On the other hand, how many great ideas go undone? So, do the right thing. If you have a great idea, tell the world. There's room for everyone. It's especially right to tell if you're not sure you can execute the idea. You can always build a better mousetrap later.

Delve into Dot Net Town
Yep, it was bound to happen. Curiosity set in and I looked to see how much this new Windows 7 thang is running. $29.95 ain't too bad. But, as we all know, that's just the beginning. The first gram is free. You and I both know that installing a new release leads to more serious drugs. I mean, apps. I mean...you know what I mean.
Anyhoo, last time I worked with Visual Studio it was pretty impressive. Visual Studio 2010 is out in beta,… Continue

By Daniel CurtisArticle: Time-Series Storage: Design Choices That Shape Cost and Performance
Every time-series database makes a set of storage design decisions: how to lay out rows, when to compress, what to partition on. These decisions determine cost and query performance more than the choice of database itself. This article works through those fundamentals from first principles, using widely available tools like PostgreSQL and Apache Parquet to make each trade-off measurable.
