Faking num lock, caps lock and scroll lock leds(www.aboutmycode.com)

submitted by mcnamaragio(283) 17 days, 5 hours ago

Some time ago I came across a post where the author wanted to turn on and off num lock, cap lock and scroll lock led light without actually toggling their state. This sounded challenging and impossible but after some googling I found a piece of code in C for achieving exactly what I was looking for. In this post I show how it works and how to port it to C# read more...

Building Expression Evaluator with Expression Trees in C# – Improving (www.aboutmycode.com)

submitted by mcnamaragio(283) 1 month, 4 days ago

Our expression evaluator has support for variables but it has a big disadvantage: values of the variables are bound by position and not by name. This means that you should pass values for the variables in the same order as they appear in the expression. On the other hand binding by name has following advantages: If you change the expression you do not have to worry about keeping order of the variables you pass in sync. In this post we are going to change expression evaluator to bind parameters by name. We will also add a new overload for better performance when we need to evaluate same expression with different parameter values. read more...

Async Iterators(davesexton.com)

submitted by mcnamaragio(283) 1 month, 27 days ago

You’ve already heard about async in C# 5. This new feature is going to improve UI responsiveness and developer productivity simultaneously, to say the least. I’ll assume that you’re also familiar with Task<T>, the generic type in the .NET Framework that provides a common model for asynchronous functions, and one of the types on which the async feature depends. read more...

The rise and rise of JavaScript(dannorth.net)

submitted by mcnamaragio(283) 5 months, 6 days ago

I’ve been using JavaScript for a while now, but only really programming in anger with it during the last year. I’ve found it in turns frustrating and enlightening, ridiculous and brilliant. I have never felt so empowered by a language and its ecosystem, so I thought I’d take some time to write about why that is. I’m starting with a ramble through the history of JavaScript, or rather my undoubtedly inaccurate understanding of it, to provide some context for where and how I’ve been using it. read more...
