What made Ubuntu so popular?

October 18th, 2007

Here are some behind reasons

1) Ubuntu – humanity towards others: This killer phrase makes anyone mad. This phrase attracts people like anything. I too got impressed to Ubuntu by seeing this phrase only! This phrase makes you feel something better in this world of monopolies. One more reason is Ubuntu’s Philosophy’.

2) Users and Community: Ubuntu got its promotion by its users and its community. They have given a hyper-hype and a world-wide free advertising. Whoever uses Ubuntu, recommends others to try it. I am still unable to find the reason for this.

3) Equal treat for everyone: Ubuntu provides same set of services and support for both home users and enterprise users. This makes home users or normal users to give a preference to ubuntu compared to other distros (feel better factor).

4) Ship It Service: One of the main innovative approach of Ubuntu to reach end users. Ubuntu delivers you free Official CDs at your doorstep. This is another reason for users to give a try to Ubuntu. People will definitely not go for paid or pirated versions when they are getting same thing for free that too in the form of CDs. While most distros, give an option for free download but never distributed free CDs.

5) Easy Installation and Clean UI: A linux newbie will like ubuntu mostly because of its easy installation steps and its clean user interface. Ubuntu’s desktops, windows’ and menus are so clean and simple, people who switch from windows to linux for first time will feel it much easier to use.

6) Ubuntu for humans: Ubuntu is for masses not for geeks. Ubuntu appeals more to normal user than an expert user. A single CD with standard installation,just like windows OS, made it much simpler than any distros. Ubuntu is focusing more on non-technical users.

People who hate Microsoft’s monopoly will definitely like Linux and who like Linux will definitely love Ubuntu.

If you haven’t tried it yet…

Try Ubuntu today itself!

Download it from here or have CDs mailed to you from here free of charge!

Go Ubuntu!!!!!!!

Source Code Search Engines For Developers

October 13th, 2007

Here is the list of various source code search engines. These let you search actual code in open source projects accumulated over the Internet.By using these source code search engines, developers can avoid the wastage of time spent on writing the lines of code for certain functions that are already exist and free to use.

Reuse is the main motive of this post.

Here goes the list

http://www.koders.com/

http://www.google.com/codesearch

For better results, search on multiple source code search engines as source code displayed by one engine may not be displayed by another or vice versa.

The above list contains almost all existing source code engines. I will be updating this list as I find out new source code search engine.

Readers are also encouraged to comment it here if they find or knew any new source code search engines.

Google and its vulnerabillites

October 9th, 2007

Google has responded to CERT-In advisory regarding vulnerabilities in Google applications by saying its systems are working fine and all vulnerabilities that CERT-In reported have been fixed before 27th Sept, the day CERT-In issued advisory.

I had heard of CERT-In before but I really didn’t know it is working so active. After glancing on its website, I realized how wrong I was. Please go and have a look if you haven’t seen that till now.Back to vulnerabilities in Google applications, this raises one serious question how safe we are and our sensitive data in this virtual world that too when we are too much dependent on Google and its applications.

Suppose, if someone hacks your Google account, imagine what could happen. Hacking Google account is like hacking my almost web presence. Take search, email, or blogging, whatever I do on the web most of times I am always dependent on one or other Google applications.
I use firefox as my default browser in spite of its several cons and its performance issues. Firefox is second most high memory consuming application on my system, first being eclipse, and it will always be a big headache in low performance pc. Still firefox cannot display many WebPages properly. Either you will get message ‘browser cannot be supported’ or ‘use IE 5.5 or later’. Have a look on this. I wonder who is responsible for such problems… firefox or website itself? And why don’t they take steps to resolve such things instead of creating inconvenience to users.

Regarding gmail, this is the only personal mail I am using now and hacking my gmail account might lead to chaos for me. It would be a single point of failure.
Long time back, when google introduced text ads inside its email, which displays ads based on your email content, there was a lot of oppose to this initiative. People were started complaining that google is unnecessarily looking into their private data. However after getting assurance from google that it is done automatically by machines without human intervention, people started trusting and gradually the issue was cleared. Although we trust google for maintaining privacy of our data, somewhere in the corner of our heart sometimes I feel am I trusting google too much or is there any other way?

Use Internet Explorer You Dope

September 27th, 2007

Whenever you try to open firefox, a new msgbox will popup onto your screen displaying a msg like “I DNT HATE MOZILLA BUT USE IE OR ELSE…” with the title “USE INTERNET EXPLORER YOU DOPE”. After it terminates the firefox automatically.

The following screenshot describes it best:

Along with firefox, it also prevents you from opening Orkut and Youtube. It gives the alert “Orkut is banned you fool`, The administrators didn’t write this program guess who did?? MUHAHAHA!!” and “youtube is banned you fool`, The administrators didn’t write this program guess who did?? MUHAHAHA!!” and closes the window immediately.

Description

  • The name of worm is W32.USBWorm.
  • It spreads through USB drives.
  • It mainly affects firefox, orkut and youtube. But it doesn’t harm any of your data that is in your computer. Everthing works fine except for firefox, orkut and youtube.
  • It also plays a .wav file (which sounds as “muhahaha!!) whenever the pop-up appear

How it works?

  • It creates a folder with name heap41a in C drive that will be disguised as system folder with hidden attributes enabled and copies all its contents in that heap41a folder.
  • The running process that is responsible for this is svchost.exe and it will be spawned under user name.
  • It will make an entry into registry so that it will be started automatically every time the system gets rebooted.

Contents of “heap41a” folder

  • Svchost.exe – This is the main executing program.
  • Script1.txt – It contains the script for displaying messages and playing sound file depending upon application invoked.
  • Std.txt – It is responsible for making registry entries and running svchost.exe.
  • Reproduce.txt – It is responsible for reproducing the directory structure and registry entries every time the system reboots or if any files or entries missing.
  • Along with these, there will be one audio file and one drive list text which contains by default all alphabets from A…Z

How to remove this worm?

  • Terminate svchost process. Remember there will be more than one svchost processes. You have to delete the one which was spawned under user name.
  • Delete the heap41a folder from your system. It will be hidden. Use advanced search options to find it. Or directly type “C:heap41a” without qoutes in run ( Ctrl +R ) to open the hidden folder. The other option is to modifying registry entry to show hidden files, goto HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Explorer > Advanced > Folder > Hidden > SHOWALL, checkedvalue and set this back to 1 which will be 0.
  • Remove the following registry entries so that it can not recur. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > policies > Explorer > Run” and remove the “winlogon” key . This registry entry will be responsible for starting up “C:heap41asvchost.exe” file everytime you start your windows.
  • Also remove any of autorun.inf file in your pen drive and a folder with .exe extension. It will be usually with name “New folder”.

It can also be removed using freeware tool “hijackthis” which can be downloaded from here :http://filehippo.com/download_hijackthis/

Note: sometimes, this worm also disables your “taskmanager” and “regedit” to prevent you to from removing it! In such case you can again enable your taskmanager and registry editor by following the instructions that are provided by microsoft.

Safari For Windows

June 13th, 2007

Apple has released Safari for Windows. After getting setup file from Veetrag, I tried it yesterday on my work pc. Apple says it is world’s best browser even on windows. It says safari loads pages 2 times faster than Internet Explorer 7 and 1.6 times faster than Firefox ( firefox is still my fav browser inspite of so many unresolved bugs in it ).

But Safari 3 public beta did not turn up to my expectations.

The most serious potential con of it is: no proxy support. I am unable to change my proxy settings as that option is disabled. I am only able to open local intranet and no internet at all. Some say it captures proxy settings from IE but still its not working even after setting proxy correctly in IE.

Only two features I found interesting in safari are snapback and private browsing.

Snapback lets you to go back where u started. Like if u searched for particular in google and you go on clicking search result nestedly jumping from parent website to further another website; using snapback you can come back directly to main original search result page.

Private browsing enables you to browse anonymously. All your browsing activities and traces will not be captured under private browsing mode.

Safari for windows is still in beta version so we can’t expect much from it. Hope it soon provides support for changing proxy settings. Well lets wait and see…
