Development Tools:
- Microsoft Visual Studio 2008
- Microsoft SQL Server Management Studio 2005

                Features

The Proposed system has two main modules

• Employee
• Admin (HR)

Employee Module:

Employee Profile

Employees could view there profiles, checkout there salaries. 

Compensatory off

When an employee works on a holiday or works overtime on a working day, he/she can apply for a compensatory off.  The duration of comp-off will depend on the extra time worked by the employee and is subject to approval by supervisor.  The comp off time can be banked for a maximum of 30 days.

Leave Application

Based on the availability of leave,  employee can apply for leave online.  

View Leave Balance

Employee can view their eligibility and leave balance against each type of leave.  Details of the leave utilized in the current leave year can also be inquired upon.

Admin Module:

This module handles the administrative functions of the system and is used by the HR department.

Employee records

Admin can view and change the employee profile, also can add new recruits and remove former employee’s.

Performance Review

Admin can review employee’s performance and skills

Leave Eligibility

HR will enter the leave eligibility of each employee, for each type of leave, at the beginning of each leave year.  The leave eligibility will be calculated based on the annual entitlement and the carry forward from prior year.

Monthly Attendance

HR can generate a monthly attendance report of  all employees in the organization.

Free Plagiarism Detector - OS X Mavericks (Eclipse Java)

Main Concept:
The idea is to compare each characters and strings in a file pair to determine the similarity rate between them. Purpose of the application is to check for copied programming codes and essays. For codes we use keywords and identifiers in order to check if both have similar logistical structures and for the essays we just use the approach of finding many similar words are there between two files.

Features:

• Supported Formats : .cs and .txt
• Check Methods "For Essay" and "For Code".
• Can upload multiple files from a folder easily.
• Similar Position Highlights available.
• Can check similarity between all the files pair by pair in-order to successfully judging cheated material.

Story Crawler - Crawling RSS News Feeds And Maintaining a Database

Main Concept:

--> Crawling news (from the Internet).
--> Storing it into the database.
--> Retrieving information from the database to the application.

The application crawls the RSS feeds from the available sources. Stores all the gathered information in a Database. Then, we can retrieve the information on different views from the Database. Information flow is automatic and we do not control what gets in and out from the database as sources provides the input and our application views shows the output.

Features:

• Crawling RSS feeds from predefined 15 sources 5 each (BBC, CNN, GoogleNews) and more sources can get added too.
• Once news is synced, application works completely offline you can not only view the details about a story but also the full news story as it stores whole HTML webpages into the database.
• Admin panel is available in-case you want to see how data is stored in the database or want to delete a news or clear the whole database.
• SQL Wildcards are supported with search options; "SeachBy Title", "SearchBy Description", "Search in provided date range".

Setting it up:

1. Download the package from the download section below.
2. Attach the database to your MS SQL Server.
3. Open project file and goto "App.config". Provide the correct connection string there or change the name "Dexter" to your SQL Server Instance name -> Save.
4. Run application -> Click on "Update Resources" button (This will build sources in the database)
   - Requires 1 minute approx depending on your internet speed.
5. Click on "Sync All" button (This will start crawling RSS feeds from the internet and retrieving and storing information to your database)
   - Requires 1-30 minute(s) approx depending on your internet speed.

You are Ready to go!!

File Transfer Protocol - C# Socket Programming

Main Concept:
The idea is based on two applications:

• The Server Application
• The Client Application

Multiple Clients can access a server to upload to or download from the server. Server can Broadcast or Multicast files to its connected clients.The Server will also keep the records of transfers into it's database.

The Server and every individual Client is considered a Socket or an Endpoint. Server will interact with each client on a separate thread this way the information of one client will not get corrupted by any other.

Features:

• Clients can upload files to the server and download hosted files from the server.

• The Server uses threaded clients approach to interact with each client.

• Server can Uni-cast, Multicast or Broadcast files.

• Server maintains a database of file transfers.

Simple Download Speed Tester - Using C# with MS Visual Studio 2008

Objective:
To develop an application which will determine the Internet's download rate.

Concept:
To determine our download rate I just used some simple mathematics by noticing the start and end time of our test download then calculating download rate by converting time into kb/sec from seconds.

This application download GoogleTalk's setup file as a test from Google's web server because let's face it, neither I have/want my web server nor it would be as reliable a Google's. We know GoogleTalk's installer is around 1.5 MB in file-size so that we won't be downloading a file too small or too big but just good enough to get our download rate right.

Tools:
- MS Visual Studio 2008 ( .net framework 3.5 )

Compatibility:
Checked with
- MS Windows XP service pack 3
- MS Windows 7 service pack 1

DFA and PDA Programming Implementation - Using C# with MS Visual Studio 2008

Deterministic Finitie Automata Implementation:
A program that can read a DFA from a text file, and support the usual functionalities of a DFA (for the ease of programming i took initial state q0 as I, set of input Σ as S and define transitions using T instead of δ). Implemented a DFA with the 5-tuple (Q, S, T, I, F) and the DFA in a textfile looks like :
Q = {p, q, r, s}// Set of all states.
S= {a, b}// Set of input.
I = p // Initial State.
F = s // Final/acceptable state(s).
T(p, a)= q
T(p, b)= p
T(q, a)= r
T(q, b)= p
T(r, a)= s
T(r, b)= r
T(s, a)= s
T(s, b)= r

PushDownAutomata Implementation:
A program that can read a simple form of PDA without lambda transition from the console or from a file or as a string within the program, and then support the usual functionalities of a PDA (for the ease of programming i took initial state q0 as I, set of input Σ as S, "stack symbols" as R, "lambda" as e and define transitions using T instead of δ). Implemented a PDA with the 7-tuple (Q, S, R, T, I, F) and the PDA in a text-file looks like :
Q = {p, q, r}
S= {a, b, c}
R= {a, b, $} //Set of stack symbols
I = p
F = s
T (p, a, e)= (p,a)
T (p, b, e)= (p,b)
T (p, c, e)= (q, e)
T (q, a, a)= (q, e)
T (q, b, b)= (q, e)
T (q, c, $)= (r, $)

Flexible Unbreakable Display Screens - Endless Posibilities - Samsung CES 2013

About four weeks ago, Samsung showed a radical 'bending' mobile phone at CES 13 in Las Vegas, which developed a feeling that the most anticipated next generation smartphone "Samsung Galaxy S4" could be a flexible OLED display smartphone.

Samsung is looking forward to the whole series of flexible displays, which will be known as Youm. Who knows that the next books will be of AMOLED instead of the papers. 

At CES 2013, Microsoft's chief technical strategy officer, Eric Rudder showed off a prototype device running windows Phone in a flexible AMOLED display.

 

Point to Ponder: If such displays are the future of the mobility then endless possibilities are waiting for us.
