LINQ to Entities CLR Methods Mapping

It's very useful to have this in mind when you write lambda expressions or use LINQ to Entities

For example, you can't compare GUID to string using ToString() Method in the lambda expression as ToString() Doesn't have a mapping, but you can use New GUID

Post to twitter programatically with 3 lines of Code!

1. Create a new web application
2. using Nuget manager, download/install Tweetsharp
3. Create a twitter application by visiting https://dev.twitter.com/apps/new
4. Go to your twitter app settings, and make sure it's a read/write app
5. Go to "Reset Keys" tab and reset keys, so the permission of read/write works with the new keys

using TweetSharp;

        //Store Keys
        string consumerKey = "-------";
        string consumerSecret = "-------";
        string accessToken = "-------";
        string accessTokenSecret = "-------";
        //Authenticate with twitter as your app.
        var service = new TwitterService(consumerKey, consumerSecret);
        service.AuthenticateWith(accessToken, accessTokenSecret);
        //Post Tweet
        var status = service.SendTweet(new SendTweetOptions { Status = "My Second #Tweet from Code :D" });

-- You can use the status variable to know the id of you posted status etc.

How to make my desktop less destractive

I Simply use virtual desktops program, which give me many desktops, if you use linux, you may be familiar with this technique .. Instead of having one desktop full of programs' windows you can have many desktops each one have a set of programs, so you can switch context and environment easily

for example, browser with social networks and E-mail clients etc. on one desktop
and the other desktop contains other browsers to test my web application and my media player

Less for Dot Net - Asp.net

Introduction

Just hit an interesting utility, LESS Compiler for .net (asp.net)
So you can leverage the power of less (Dynamic CSS) in your .net web applications

Usage

Just add the following to the Web.config

<add type="dotless.Core.LessCssHttpHandler,dotless.Core" validate="false" path="*.LESS" verb="*" />

<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler,dotless.Core" />

So, now you added a handler for .less files

Then configure it

<dotless minifyCss="false"
 cache="true" />   

*You can also use it from the code

Less.Parse("div { width: 1 + 1 }");

which will produce 

div {
  width: 2;
}
