C#/.NET Fundamentals: Of Lambdas and LINQ

This is a quick presentation I threw together for a group of developers who requested a quick primer on using lambda expressions and the more common LINQ extension methods. It seemed like a good general knowledge presentation so I decided to upload it to slideshare and reference it here as well.

This is not meant to be a comprehensive discussion of everything that lambda expressions and LINQ have to offer, but is just sort of a very basic introduction to help those less familiar with reading and using them in code get used to them. Lambda expressions and LINQ have a very great ability to make code more concise, and thus easier to write, test, and maintain.

That said, their syntax and behaviors do take some getting used to if your shop hasn’t used them widely before. Once they become part of your .NET vocabulary, though, believe me you will never want to do without them again!

Feel free to critique and/or pass it on!

Vim Search and Replace: The Ultimate Guide

One :%s command replaces every match in a file before a find dialog would even open. The Vim substitute patterns worth the muscle memory: flags, ranges, capture groups, and multi-file edits.
