Apple Quietly Releases Safari 3.2

Sunday nov 16 apple launched the update to safari version 3.2. The feature includes various feature to upgrade like:-
The notable feature is that it finally adds anti-phishing technology, an area where Safari has lagged behind competitors.
Aside from that, it provides some security fixes, improved JavaScript performance, and a slightly newer version of Webkit, pulling their Acid3 score up to 77.

Google iPhone Voice Recognition App



GOOGLE voice recognition search application for the iPhone, originally set for launch on Friday, will likely go live sometime Monday, we’ve heard from a source with knowledge of the situation.
Apple left Google completely in the dark as to why the app didn't make it into the store on Friday, as previously planned. Google keeps an airtight lock on their news, and John Markoff's piece in the NYT was supposed to accompany the app's release

The good news for Google and all that were eagerly awaiting this app, is it will likely become available come Monday. This news comes from a source with insider knowledge of the situation (according to a report at TechCrunch). Google has apparently had little contact with Apple during this period, and have been getting updates on the situation via the iPhone developer tool which has had a status of ‘in review’ for the last few days .

Wars-of-browsers

There are the periods when Netscape & internet browser explore had the war for there place. Brits scientist sir Tim Berne less had never thought his 1991 which was renames Nerves would lead to origin a various change in 2008 World Wide Web.

Browsers are important tool for searching internet. Here I try to find which is great among




Fire Fox 3

Mozilla one of the failure browsers among the open sources users breaks the records by downloading 8 million in just 24 hours. Firebox has a simple 8 clean logout with light-weight 78MB. It is say 8 have rich a. it have various active security feature like (anti-phishing, pop-blocker, password managers, parental controls).

The area that lacks are speed & performance firebox is now of the blocks talking marginally longer. It takes about 1 to 14 at first startup & four to eight seconds to startup later.
Fire fox is great with its feature like bookmarks & history management, search engine integration & tabbed browsing. It is far ahead with thousands assours to pick. The manager is an easy way to in stall as sour by listing popular us without need to open a webpage.
Book-mark is done clicking star in the location tab change to golden means page is Booked.
Password manager is unobtrusive with a discreet toolbar shown instead of the dialog box that offers to remember passwords.
Spelling checking & searching on page is also well important.

Google Chrome

Every product has its important. When a goggle products comes then its goes to box in the web.
Since its logo looks like a pogo ball bat it has not left Google color.
Chrome is just easy to use simple & looks great. There is a tab bar in place of the little bar with no menu bar & tool bar cluttering the interface. The one thing in the address bar (also known as the amni bar) which doubles up as a search bar. when opening new tabs, chrome displays a preview of sites in the new tab which is like operas speed dial. There are no advance navigational options – only the forward/back/refresh.

Chrome is not loaded with feature but user can create application shortcuts to webpage on desktop. A handily feature that is also available in chrome is resizing areas like the comment box in the webpage. Besides that chrome is same like other browsers having basic bookmaking, full search engine functionality, password management etc.
Chrome logs more system resources than any other browsers chrome loads the site speedy but it had issues with heavy content sites.
Chrome is great but still at early stage to compare with established browsers.

Opera

Opera is a feature rich as firebox is but in narrowly loses out to the later. It has lots of feature that are hard to find in other browsers like e-mail. IRC & Bittorent clients etc. An option for controlling opera with voice commands is available, but it’s only for 2000/Xp has not been perfected yet. Operas mouse gesture is another feature which is useful for the someone who wants to navigate quickly. Data sharing is possible through the opera link a free service that synchronizes book-marks, speed dial entries, notes & other personal data between multiple computers.
Perspire boasting so many innovative & unique feature it disappoints as it is not yet, open source. Opera is erratic. Sometime its really quick but often lags behind the navigation time when compared to firebox & I.E
Opera disappoints on its Book-Marks as it does not provides on click bookmrking, editing & managing in ease. Password management still fit primitive with irritating boxes pop such when a password is entered. Search engine integration is not yet truthful, it provides mine default engine but does not provide good integration. Opera provide basic history management.

Internet Exploer-8

Microsoft latest offering is IE8 beta. Which claims its fast safe easy? Ie8 have lots of add-ons. Some free some non free
Accelators that provides easy access to various web services from any WebPages with just few mouse clicks. Another unique is web slices. Microsoft uses this technology to automatically trace sites. Using slices user can keep up frequently updated sites directly from favorite bar. Ie8 has a separate process for individual tab in browser windows.
Lacking feature is the download manager which is limited. IE still is copyright of Microsoft and no proper password mgmt.

How to set folder permission

Linux (and almost all other Unixish systems) have three user classes as follows:
  • User (u): The owner of file
  • Group (g): Other user who are in group (to access files)
  • Other (o): Everyone else

You can setup following mode on each files. In a Linux and UNIX set of permissions is called as mode:

  • Read (r)
  • Write (w)
  • Execute (x)

However, above three modes or permission have different meaning for file and directory:

Linux Read mode permissions

  • Read access on a file allows you to view file
  • Read access on a directory allows you to view directory contents with ls command

Write mode permissions

  • Write access on a file allows you to write to file
  • Write access on a directory allows you to remove or add new files

Execute mode permissions

  • Execute access on a file allows to run program or script
  • Execute access on a directory allows you access file in the directory

Octal numbers and permissions

You can use octal number to represent mode/permission:

  • r: 4
  • w: 2
  • x: 1

For example, for file owner you can use octal mode as follows. Read, write and execute (full) permission on a file in octal is
0+r+w+x = 0+4+2+1 = 7

Only Read and write permission on a file in octal is
0+r+w+x = 0+4+2+0 = 6

Only read and execute permission on a file in octal is
0+r+w+x = 0+4+0+1 = 5

Use above method to calculate permission for group and others. Let us say you wish to give full permission to owner, read & execute permission to group, and read only permission to others, then you need to calculate permission as follows:
User = r+w+x = 0+4+2+1 = 7
Group= r+w+x = 0+4+2+0 = 6
Others = r+w+x = 0+0+0+1 = 1

Effective permission is 761.

chmod command

To setup file permission you need to use chmod command:
chmod {mode} {file-name}

To setup file permission 761 you need to use chmod command as follows:
# chmod 0761 file
To setup a file readable by anyone and writable by the owner only:
# chmod 644 file
To setup a file readable/executable by everyone and writable by the owner only:
# chmod 755 file
You can change permissions for all files and directories within a directory by using the -R option on the chmod command. For example, to setup others read and execute access to all files and directories (and files and directories within directories), you need to type command as follows (i.e. change the modes of the file hierarchies rooted in the files instead of just the files themselves):
# chmod -R 755 directory-name/

However, Linux (and UNIX) stores and process user database in different format.

The root user

  • The root user is the super user.
  • The root user can control entire Linux system including files, process, applications etc. The root user has full access to system.
  • You should not use root for day-to-day tasks as root has full system access.
  • Never ever, give root password to anyone.

For more information see What defines a user account?

User database

  • User database is stored in /etc/passwd file
  • User passwords and password expiry information stored in /etc/shadow file

Group database

  • User group information is stored in /etc/group file

UNIX/Linux User rights

There are two types of user rights (traditional):

  • File level user rights or permissions granted using chmod and chown command
  • Administrative (root) level rights granted using sudo.

If you type the following command:

$ ls -l

You’ll see something like the following:

-rw-r--r-- 1 indiver webusers 14814 2006-07-26 13:25 working-nixcraft.txt 

Look at 3rd, 4th and last columns.

  • vivek is username or the owner of the file (userid)
  • webusers is group name, so all users in webusers can access file working-nixcraft.txt
  • working-nixcraft.txt is the file name.

As the root user you can change or setup user file related rights/permission using chmod and chown command.

Task: change file owner and group

Consider following example:

$ ls -l foo.txt

Output:

-rw-r--r-- 1 vivek webgroups 8 2006-08-08 17:57 foo.txt

Change files ownership to tony user:

# chown tony foo.txt
# ls -l foo.txt

Output:

-rw-r--r-- 1 tony webgroups 8 2006-08-08 17:57 foo.txt

Change foo.txt group to ftpusers:

# chown tony:ftpusers foo.txt
# ls -l foo.txt

Output:

-rw-r--r-- 1 tony ftpuseers 8 2006-08-08 17:57 foo.txt

You can also operate on files and directories recursively using -R option. For example setup /var/www/html ownership to user lighttpd including subdirectories:

# chown -R lighttpd /var/www/html

Task: change files access rights/permissions

You need to use chmod command. Please refer the old article - how Linux file permissions work.

Task: Grant administrative rights to a normal user

You need to use sudo tool. It allows a permitted user to execute a command as the superuser or another user, as specified in the /etc/sudoers configuration file.

A note for Ubuntu Linux users

You can use chmod and chown command to setup user rights. Make sure you prefix all commands with word (command) sudo:

$ sudo chown tony:ftpusers foo.txt

Q. How do I use chmod and chown command under Linux?

A. Use chown command to change file owner and group information. Use chmod command to change file access permissions such as read, write etc.

chown command

chown command changes the user and/or group ownership of each given file.

For example following command will setup user and group ownership to root user only for /backup directory:
# chown root:root /backup
Set user user ownership to root user and allow any member of ftp group to access file.txt (provided that they have sufficient read/write rights).
# chown root:ftp /home/data/file.txt

HOPE THIS TIPS WILL HELP TO KNOW THE THE BASIC COMMAND OF LINUX ADMIN

Red Hat Linux Video Player Installtion

You can use VLC or mplayer both can play movies, mp3, dvd and so on. However, these packages are not part of default installation and not supported by RedHat. You need to install 3rd party repo such as RPMforge to install the package.

Dual boot linux and mac osx leopard kalyway 10.5.2



Dual boot linux and mac also we can make triple boot with vista is very hard than I think and finally I got it. I spent 3 days to did it succesfully. Ok, this is way of my installation. I made in single hard disk, Pentium 4 3.0ghz, 1 gig RAM, Nvidia geforce fx5500 256mb, 80 gig hard disk drive.

Preparation before make dual boot


1. You must already have Super Grub Disk before install all this method. Burn iso image in your mini cd. Find SGD at http://supergrub.forjamari.linex.org)

2. EasyBCD for windows. Download here: http://neosmart.net/dl.php?id=1

3. Vista OS, Mac OSX and Linux OS' dvd/cd.

4. Burn gparted iso in your mini cd.


Install vista in your pc

Vista or windows xp, it must install in first partition and absolutely you're already have it in your HD. But if you're advance user, forget my advice here. :p We can install windows anytime, anywhere actually...

After installing windows, you can use easyBCD and make a new MBR. Just choose linux, windows and vista in MBR. Good software for all download free here:
http://neosmart.net/dl.php?id=1

Install Vista first.. you can choose any partition.
After installing Vista, install EasyBCD and create Mac in MBR by EasyBCD.

##############################################################################

Linux
Ok, now I already have vista. Install linux in any partiton, I made logical partition and choose ubuntu 8.04.1 as primary and opensuse kde 4 as extended. I don't working with lilo, I was using grub. In terminal, edit menu.lst,

$ sudo gedit boot/grub/menu.lst

and add this below or above ubuntu title. It is from windows menu.lst. We will repair it later. Don't panic if it won't boot to mac.





title Mac OSX
root (hd0,0)
makeactive
chainloader +1


Reboot pc and restart linux back. Because I have two linux, so I boot to times to login to ubuntu and opensuse.

#################################################################################################

Mac OSX
Actually, you can install mac or linux before or after. It's up to you. I install mac osx 10.5.2 kalyway in my pc pentium 4. But after iatkos 10.5.4 release, I installed iatkos. This is how to install kalyway. To install iatkos 10.5.4, check out at my post here:
http://linux-guider.blogspot.com/2008/09/installing-iatkos-1054-is-easy.html

-Insert dvd, boot..
-press F8
-enter -v and wait. Grab your "Nasi Lemak or Roti Canai". Eat until macosx ready for next work.

- Utilities -> Disk Utility in the menu bar. Find the hard drive in the sidebar you want to install Leopard.
- Erase -> Mac OS Extended (Journaled) format. (Rename, no space or special character)
- quit Disk Utility and head back to the Installer.
- utilities - terminal
- enter this command

fdisk -e /dev/rdisk0
flag 2 <--note that flag 2 is my mac partiton number two
quit
y

then, you can quit terminal. Quit Disk Utility and head back to the Installer.

-Hit Continue at the Welcome screen, agree to the terms, and then be sure to hit the Customize button before proceeding with your installation.
-install package comes with individual settings that match specific motherboards. Buti I leave all default. I don't want to feel head-ache.
-When the installation is complete (around an hour), let your computer restart, pop out the install disc, and sit back in wonder as Leopard runs on your PC in full 10.5.2. Watch start-up movie and grab your "chicken chop". Register your profile and password and don't register to mac.

WHAT HAPPEN IF I GOT HFS + ERROR?

After installing Mac, you will got error message in boot such as HFS+error in bootloader. USE SUPER GRUB DISK. SGD is useful tool for recover linux grub and windows MBR.

Free iso download here:
http://supergrub.forjamari.linex.org

Repair grub

Use super grub disc to REPAIR menu.lst. Just edit by type e and enter. Change hd0,0 to hd0,2. Test boot.. If fail.. change to hd0,3 or hd1.0 or whatever until it boot. All menu.lst attaced here is for example. If you have a doubt to boot mac or windows in grub, choose title mac osx in grub menu, we will edit it please enter:

e

on title macosx, change root (hd0,0) to

root (hd0,1)

it's mean, you will boot in partition number 1. Press enter and:

b

You will boot to mac osx or windows. If still doubt, you can try any number, Look mine here..





title Mac OSX
root (hd0,2)
makeactive
chainloader +1


WINDOWS GONE??

Repair windows startup using windows cd/dvd.

MAC OSX GONE?


Never gone, but it is hidden until you find it back with easybcd on WINDOWS or supergrub disk in linux.

REFIT?

I never use refit.. Please tell me what is refit?? lol

Conclusion
1. Before installing three of this OS, make sure you have make a back up copy of your important data.
2. Burn SGD in mini vcd and keep it as your important hardware.
3. Keep easyBCD.exe in you removable disk.
4. maybe gparted iso also useful.

Good luck!

installing iatkos 10.5.4 is easy!!



Wow.. it is easy to install it. No more hacking, just doing simple method except if you have other OS partition. iatkos 10.5.4 is more quiet than kalyway. My fan turning in low speed.
Second time I did it. I was amazed, it really easy to install.


How to install iatkos 10.5.4?


First time I follow a guide but it doesnt work.
Actually, it is just 2-3 steps depend on your choice. Don't add nforce -v or toh -v or whatever. Just enter, -v for verbose mode ok?

1. For fresh install:

utilities - disk utilities - view partiton - choose partiton - choose hard disc - erase tab - volume format "mac os extended (journaled) - name "OSX or whatever, avoid space" - erase tab - pop up erase - DONE!! - QUIT

2. But I have other OS, forget step 1 and..

utilities - disk utilities - choose hard disc - erase tab - volume format "mac os extended (journaled) - name "OSX or whatever, avoid space" - erase tab - pop up erase - DONE!! - QUIT

3. multi OS boot (forget this if you just want to install macosx only):

utilities - terminal

fdisk -e /dev/rdisk0
flag
quit
n

then, you can quit terminal.

4. Back to mac os x instaler...

continue - agree - select destination - continue -customize - select kernel ToH 9.2 only - install - skip - reboot

5. You're finish. I don't change anything in customize tab!! It saves me!! Reboot pc and take out your dvd and put it in case while boot. If macosx don't want to restart, help it by pressing restart button. (I'm not kidding lol)

6. So now, watch a start up movie and register yourself.

Pro

Easy install than other version
Install in 25 minutes

Cons

Sometimes a desktop blinking after install X11.dmg - solved after install Kernel ToH 9.2
