Heard alot about the KOBO Here it is

kobo e-reader

The latest Good E-Reader news has the Kobo electronic reader going on sale in Canada this Sunday at Indigo book stores and has a follow up in Boarders stores later on in May, in the United States.

The main great thing about this e-reader is the cost $169.00, which is a cost effective alternative to more expensive electronic readers. The principle behind Kobo is allowing e-reading anytime on whatever device the consumer wants, as the platform is compatible with Research In Motion, BlackBerry, Apple Inc.’s iPhone, and others. When an e-book is downloaded onto an e-reader or Smartphone using the Kobo app, it remains in the user’s “online library,” meaning the e-book can be read on multitude of devices. The Kobo also takes home the prize for dedication of purpose. You can read books on it, and that’s it. No monochrome photo browsing, no music player, none of the extraneous features found on other devices that people end up never using. It’s for reading, plain and simple. The Kobo book store is compatible with most major Smartphone’s, computers, Netbooks and e-readers.

The device itself features four buttons on the left edge: one that takes you to the home screen, one that calls up a menu of options for the book you’re currently reading, another that brings up display preferences (typeface, magnification, and the like), and a “back” button that takes you to previous screens. An on/off switch is located on the top, and a big blue membrane navigation button found on the bottom right of the face lets you flip pages and surf menus. That’s all there is to the interface.

The process of transferring books from your computer to the Kobo is a breeze. You can either drag-and-drop (it supports PDF and ePub files) or use Adobe’s Digital Editions software to manage and sync your library. It also has built-in Bluetooth, allowing users to purchase books via smart phone and send them straight to their Kobo.

Kevin Restivo, analyst at IDC, sees Indigo “hedging its bets” with Kobo. On the one hand it has an e-reading operating system that works on multiple devices, and on the other it’s introducing a single-purpose device when the market is hot for e-readers.

The Kobo eReader is likely to go on sale in New Zealand next month at the same time as Whitcoulls and Borders launch the country’s first eBook store.

A spokesperson for REDgroup, which owns Whitcoulls and Borders, said more than a million eBooks would be available for purchase on the two retailers’ websites when the store launched in May.

Kobo will then be soon launched in Australia at the end of the month.R REDgroup had partnered with Canadian eBook firm Kobo to provide the service and it was likely that the company’s upcoming Kobo eReader would also go on sale locally when the stores launched, she said.

Managing director Dave Fenlon said the company had completed the integration of its three bookstore brands and was now looking for growth opportunities, with the Kobo electronic book platform to be launched next month in league with Canadian bookseller Indigo.

In addition to Kobo-branded readers to be sold in Redgroup’s stores, the company’s e-books will be accessible on other devices, including Smartphone’s, computers and iPad’s.

REDgroup was now Australia’s largest online bookstore, with more than 2.5 million titles available.

We have a comprehensive review of the KOBO in our latest MAY edition of the Good E-Reader Magazine! If you are interested in Kobo, E-Readers, or Slates this is the must buy for you! It is only $1.99 for the first issue.

What is Josephus Problem


This is an interesting programmingproblem know in the literature as Josephus problem. The problem is given as:

1. Suppose there are n children standing in a queue.

2. Students are numbered from 1 to n in the clockwise direction.

3. Students choose a lucky number say m.

They start counting in clockwise direction from the child designated as 1. The counting proceeds until the mth child is identified. mth child is eliminated from the queue. Counting for the next round begins from the child next to the eliminated one and proceeds until the mth child is identified. This child is then eliminated and the process continues. After few rounds of counting only one child is left and this child is declared as winner.

Josephus Problem Animation

Implementation

It is required to write a program to identify a winner of the game. Inputs to the function are two parameters.

n: number of children
m: lucky number

function returns an integer identifying the winner


int winner (int m, int n)
{
                                 queue q;
                                 int i;
                                 init (&q);             //create a queue of n integers, numbered from 1 to n. Number I stands for ith child
                                
                                 for (i=1; i<=n; i++)
                                                enqueue (&q, i);
                                 for (j=1; j<=n; j++)          //n-1 iterations to eliminate n-1 children
                                 {
                                                for (i=1; 1<m; i++)            //skip m-1 children
                                                {
                                                                x=dequeue (&q);
                                                                enqueue (&q, x);
                                                }
                                                x=dequeue (&q);             //remove mth children
                                 }
                                
                                 x=dequeue (&q);            //last child winner
                                 return (x);
}

What is Firmware and Custom Firmware

What is Firmware and Custom Firmware 


Definition and Difference Between Original Firmware and Custom Firmware .


What is Firmware ?


A firmware is main software ,installed in main chip (flash memory called ROM) of all electronic device to control and give permanent instructions to device hardwares . ROM is random access memory which can be rewritten or erase. 
No matter its Smartphone,Tablets or other devices,the definition of firmware is same in all the electronic devices. A firmware works like human brain, which control and instruct all the part of human body. 

What is Stock Firmware,Stock Rom or Original Firmware ?


A firmware is also called Stock ROM which means the original firmware of particular device from company or a same copy of software which were installed by company during manufacture . A modified firmware with different version called update . When the companies modified their firmwares to remove the bugs ,more compatibility,or better performance and efficiency ,called updates.Firmware Updates manage by versions.   You can install firmware updates in many ways i.e if you have smartphones or tablets you can install Android updates (for example 4.0,4.1,4.1.2,4.2.1,4.2.2,4.4)iPhone or iPad (IOS 7.1.1,IOS 8.0)etc. by WIFI (OTA) or by downloading firmware from companys web page. The original firmwares are always needed when your device does not respond properly ,dead or generating multiple software errors to make it alive again. 


What is Custom Firmware ,Custom Rom?


A  firmware which modified,edited, injected new features,ripped out stock apps,optimized kernel with no limitation by individuals (Developers) called Custom Firmware or Custom Rom.  The most important feature of Custom Rom is , you can update firmware to those versions which is not available for you device. Custom firmwares are based on extra utilities added by developers i.e  extra themes,long battery,speed,graphics ,explore the whole devices options added into custom rom. 
For reference in Iphone you can preserve baseband to avoid baseband update with custom firmware or in android devices you can have extra features like installing apps in memory card,rooting etc.
This post and content is based on best of my knowledge. If someone would like to add something in this post please write it as comment and I will add it to post. Any suggestions would be considered  as compliment.

Check Your Mobile is Genuine or Fake



Mobile Markets are full with Fake Phones and mobiles are being sold as original even with Branded tags next to it the replica phones are kept in the market that looks similar to the original phone, to make sure whether your phone is original or fake there would be two ways of checking it. These methods will help you during purchasing a used cell phone.



Check the following Features:

Be alert about the spellings for example Soniericsson, Nokia and Samsung

Warranties: Always ask for 12 months warranty certificate from the phone manufacturers; never trust on an oral agreement with the seller. Fake phones come with a short warranty periods as counterfeiters cannot give guarantee it will last so long.


Check handset in all aspects completely: Some people take phones home without testing it first. Some dealers make you fool and encourage this, knowing the handset is fake. As you check it out, you might observe some points of low performance or other issues such as memory which is cheap quality photos.


Appearances: like dull colours, screen size, quality of printing and paint finish, Fake built quality difference in weight, logos, location of buttons and battery, missing functions, quality control and holograms and lack of quality.




The other method is examining or checking Phones quality through 15 digit IMEI code


Dial *#06#


Dial *#06#


IMEI stands for ( International Mobile Equipment Identity). This is a 15-digit number and might be found in the packet of the mobile phone as well. It might be found by eliminating the back cover and it might be located on the battery.


The IMEI number may be as below:



IMEI CODE

3 6 9 3 9 5 0 1 2 3 5 5 6 7 8 


Now view the 7th and 8th digit. These two digits will make sure your phone’s quality!


  • If the seventh and eighth digits are 00 this shows your cell phone is made in Original Factory which makes sure the best quality.



  • If the seventh and eighth digits are 01 or 10 this shows your cell phone is made in Finland which is best quality.



  • If the seventh and eighth digits are 13 this shows your cell phone is gathered in Azerbaijan which is too bad. And it is also unsafe and dangerous for health!



  • If the seventh and eighth digits are 02 or 20 this shows your cell phone is gathered in Emirates which is very cheap quality. If the seventh and eighth digits are either 03/30 04/40, this shows your phone is manufactured in China but its good quality. But is bad either as 00, 01 or 10.



  • If the seventh and eighth digits are 05 or 50 this shows your cell phone is made either in Brazil or USA or Finland.



  • If the seventh and eighth digits are 06 or 60 this shows your cell phone is made either in Hong Kong, or China or Mexico



  • If the seventh and eighth digits are 08 or 80 this shows your cell phone is made in Germany which is good and fair quality.




  • This will help and facilitate you to select the good one but these tips might not work with the Sony Erickson Mobile Phone.
