Introduction to Android Platform for Beginners.

android-techtricks

In this post ,I am going  to share some of the interesting facts about Android platform which was discussed in an introductory session conducted by worldlink at le meridian,Bangalore.

  • Though Android platform is basically for mobile phones  it has been successfully implemented in  various other devices such as E-book Readers,Navigators and Netbooks.
  • Android runs on Dalvic Virtual Machine,which is a register based virtual machine developed by google , unlike the usual one which is stack based.
  • Android requires high-end hardware i.e a minimum of 400Mhz  processing power and 128MB RAM and efforts are made to minimize high-end hardware dependency.

booting ubuntu from media direct and windows 7 fresh dual boot on dell xps 1330

ubuntu-910-vs-windows-7

This post tells you about how i achieved a special “dual” boot -> ubuntu from media direct button  and windows 7 from the regular power button on dell xps 1330.

In the usual installation ,one would install windows 7 first and later install ubuntu. In this usual method, GRUB 2 would be the default boot loader and upon selecting windows 7 from the option list provided by the GRUB while booting,Windows boot loader would be called.Here,if you are selecting windows 7 ,you would be loading both GRUB2 and then windows 7 boot loader as well which would increase the System boot time.

Why did i decide to boot ubuntu from media direct button?

Enabling Server Side includes(SSI) on fedora core default

With Server Side Includes (SSI), you can include other HTML pages inside one web page. You can even generate some dynamic content, such as adding a “Last Modified” field on the page or printing environment variables. This section explains how to enable SSI on your Apache server.

If you are using a clean install of Apache from the Fedora Core RPM packages, SSI is not enabled by default. To begin, open /etc/httpd/conf/httpd.conf and locate this line :

<Directory "/var/www/html">

Directly under that line is a stanza describing the Options directive that immediately follows. Simply add “Includes” to the end of the Options directive like so,

    Options Indexes FollowSymLinks Includes

Next, look for this line:

AddType text/html .shtml

It should be uncommented by default. If it is commented out, simply uncomment it. That’s all ! Files with the extension .shtml are SSI files. If you wish to use an .shtml file as the default page for your website or directory, you will need to make one more change. Locate the DirectoryIndex directive and add index.shtml to it, like so :

DirectoryIndex index.html index.html.var index.shtml

“unknown error” (kCFErrorDomainWinSock:10054 problem solved

Recently i was configuring asp.net development server and fiddled up proxy server settings in internet explorer.since i am avid user of firefox i rarely bothered about IE.yes,firefox worked but IE did not.

Thats not the only problem .none of the updates would work.it seems all applications upgrade refers to proxy server settings in IE.to my surprise even safari did not work.it was intelligent enough to show the error message directly unlike IE.

the error message was “unknown error” (kCFErrorDomainWinSock:10054.

Uninstalling/ Removing Fedora the easy way

This post is about Uninstalling Fedora from your Computer the Easy way.

I assume before you Dual Booted with Fedora you used Microsoft Windows XP.

i also assume the reason you installed Fedora was to help you in your college course work and reason you are uninstalling is you want to get back to your comfort zone -”win xp”. (my 2 bits :its always betterto stay out of your comfort zone to get an “edge” over your competitors).

if you are still reading this i believe you are determined to remove fedora, maybe you want to install more friendly version of linux ;) (try ubuntu)  or you want to regain your precious hard disk space.

coolest geek t-shirts

Front: How many Java programmers does it take to change a light bulb?
Back: You’re still thinking procedurally. A properly designed light bulb object would inherit a change method from a generic light bulb class, so all you’d have to do is send a light bulb change message.

Facebook users ! beware of fake facebook sites.

if you are a facebook user  and you recieve a mail in your inbox claiming to have sent from your close friend  asking you to check out a link then watch out.the site you are logging in might not be the one it looks like.

many of these links are of .be domain.a quick look up in google revealed that .be is a belgium domain which can be obtained for free by anyone.and that means crackers  are  trying to trick you by making you logging into a false website which has the looks of facebook.

some of the sample domains are listed below

  • httx://goldbase.be/
  • linkteria.be
  • whiteflash be

Web forgeries are designed to trick you into revealing personal or financial information by imitating sources you may trust.

Entering any information on these kind of web pages  may result in identity theft or other fraud.

Happy Surfing!

how vulnerable is your windows password to brute force attack?

The difference between security code and application code is, when application code fails, you find out right away. When security code fails, you find out 4 years from now, when a DVD with all your customer’s credit card and CVV2 information starts circulating in Estonia.                                      Matasano Chargen

i came across an article in digg which was about “63 things a geek should know“.quite an interesting article.somewhere down the line i found this article about breaking into windows and linux operating systems by obtaining their passwords. Read More »

have you updated your nokia 6300 firmware to version 7.21?


Nokia 6300 has been the topselling phone for nokia from past few years.this ultra slim phone is now costing around 7000 rs which was initially selling at 12000 rs.

there were couple of glitches with the previous firmware which i had been using (6.01 firmware) all these days.

  1. one could not add the same person to multiple groups in the contact list.
  2. editing the contact information would lead to “operation fail” error most of the times.the phone was unpredictable

i was wondering when these people will address these issues.

with the 7.21 firmware these issues seem to be solved,though i havent tested it properly i have had no problems so far.

for those who are upgrading the firmware for the first time get your nokia software updater software from here.

why i hate nero?:free and paid cd and dvd burner alternatives


Nero has been the most successful cd and dvd burner software all these years.but lately i am finding it really difficult to do even the basic tasks such as copying cd’s and dvd’s.after the nero 7 ,the design of the software with respect to user interface underwent a major make over and as far as i know majority of the users didnt like it.

Thats when magazines and tech journals like digit,chip and others started giving out free burner alternatives to nero which are much more simple and take a miniscule space on your hard drive unlike nero which takes up half a gig or more.the only downturn is  you are sacrificing some of the functionality which you would rarely use.

one such alternative which i personally liked is

burnaware

you can use the free edition for most of the basic stuffs and purchase the paid one only if you need the exta functions.

let me know which other free alternatives you like the most

happy burning!!!

adsense and dreamweaver spry tabbed panels


i was designing a new site where i was planning to integrate adsense into the html pages.i had a dreamweaver spry tabbed panels inserted in the html page.as we all know adsense allows only 3 ad units per page.

where i went wrong…..

so what i thought was i’ll integrate 2 ads on html page (outside spry tabbed panels) and the 3rd one inside the spry tabbed panels,like one ad for each tab.
