"WHERE IN" for LINQ

I was trying to convert the following query to LINQ :

select Osid,OsName,CompanyId,Pid,description,type from OrganisationStructure where OSId in (" + location + ") and type='location'

Where location is a string like '123,2345,12356' ...
What I got on some places the where in clause is converted as bellow :

List<string> locList = location.Split(',').ToList();
var orgloc = (from b in context.OrganisationStructures
                                  where locList.Contains(b.OSId.ToString()) select new{b.OSId,b.OSName,b.CompanyId,b.pID,b.description,b.Type});

This was not giving any error on design time. But while debugging I got the following error:

LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression

The reason is LINQ to SQL doesn't know how to translate the .ToString() call to a SQL expression.Therefore I had to change it like bellow:

var orgloc = (from b in context.OrganisationStructures select new{b.OSId,b.OSName,b.CompanyId,b.pID,b.description,b.Type}).ToList().Where( s => locList.Contains(s.OSId.ToString()) && s.Type.Equals("location") ) ;

Refrence :

• Vikram's weblog
• A Stackoverflow answer that gave me some idea of first getting the entire list and then process the where. 

Opensource Chatbots/Chatterbots

I have started playing with a Program-O a chatbot that really worked for me. Liked it very much and while googling a little more I have found there is a good community who work for creating chatbots - thought I might list them so that I can check them later; Right now I am just listing and will update this post once I check each of them :

• Program-O: php, MySql
• Pandorabots: php, MySql
• Hubot:  Node.js
• Verbots: Desktop application
• Alicebot: I think they have formed a standard and based on that there are some popular chatbots.

Some other good references I have got from Chatbots.org

Opensource applications with CodeIgniter

So far I have a crash for CodeIgnier and whenever I start developing for myself my first preference is always been CI :)
In this post I will be listing some of the Opensource projects built on top of CI :

Dev boards to make your own custom computers !

The improvements of computers and the electronics has given (and possibly giving) birth of some evaluated couple of developer (bread !!)boards - They are more like some smart super-micro[bigger than nano :P] computers. Just wanted to go through some of the famous ones and list them as I go.
Somewhere I found that somebody was depicting the story as

Then Massimo Banzi invented a new single board: Arduino.
And everyone was happy. At last, prototyping was easy, cheap, and fast.
Then the unexpected happened: David Braben invented the Raspberry Pi. Everyone became happier. Prototyping became easier, cheaper, and faster.
The story does not end here: now we have CubieBoard, Gooseberry, APC Rock, OLinuXino,Hackberry A10, et caetera.

Here is a list of the boards I was studying to pick one up from :

• Raspberry Pi

 
Some fun stuff that you can do with Raspberry Pi
If you are a Windows user and don wanna wait to give it a look; check the follwoing link.
http://sourceforge.net/projects/rpiqemuwindows/. And here's a post how to start you DotNet[actually mono] programming on Raspberian

• Hackberry Dev board

• Arduino

• Cubieboard

So far what my understanding is depending on the project you want to do/budget you have you have to carefully choose from the list. But for me I might go with Raspberrypi.

To find out a comprehensive comparison of the feature and price the following link can be checked.

Testing the performance of a web application

Currently, I am working with a web application and one of the main duty is to improve the performance of the application. I am trying to reduce the page refresh time first. Here I m going to note down all the tools and techniques I am utilizing.
To identify exactly what is bottle-necking I used the following tools:
FireBug
IE Developer tools
Yslow
Pagespeed
Fiddler
I needed to compress/minify my css and js files. I got some tools that are of high rank. But finally I wrote my own tool to perform the same :
https://github.com/marifrahman/WebResourceCompressorForm

Some of the clients has very slow internet connection. Therefore I needed to test the site using low speed internet  To accomplish that following tools were very useful.
Sloppy
