Google has updated the beta version of its Chrome for Linux with a variety of fixes designed to make the browser more reliable, the company announced Thursday. Version 5.0.307.7 of Chrome for Linux addresses several bugs that were problematic in the previous version. One fix, for example, changes an out of memory killer mechanism so that it terminates runaway tabs before it closes the browser when memory is low. The upgrade was released in tandem with a similar update to the Mac version.

Mindcraft 2.0: Firefox Comes of Age

Remember Mindcraft back in 1999? Not many people do. It was when Microsoft "proved" Windows NT was faster than GNU/Linux. That backfired, and so has Microsoft’s latest paid benchmarking: this time of Internet Explorer 8 vs. Firefox, by NSS Labs. It just goes to show that Microsoft is now officially worried about Firefox in the browser sector.

When i try to enter in the admin folder i am not able to access it. It is giving error "Access is denied"

My smb.conf file is as above

————————–smb.conf————————————-

Code:


# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
http://www.samba.org/samba/docs/Samb...Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#---------------
# SElinux NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SElinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SElinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

How to Enhance Your Browser with Greasemonkey

How would you like to be able to customize the layout of the Google homepage? How about add better video controls and a download button to YouTube? Or set a profanity filter that works across all websites? Maybe remove all the “What type of leafy vegetable are you?” quizzes from Facebook? These are very few of the things that can be done with Greasemonkey. By itself, Greasemonkey does essentially nothing. At least, nothing that you as a user would notice. To really use it, you download Greasemonkey scripts which all have some special purpose. For example, right now I’m writing this from a browser with Greasemonkey installed, and I’m using scripts to enhance YouTube, Facebook, and Google Images.

Netscape Founder Backs New Browser

It has been 15 years since Marc Andreessen developed the Netscape Internet browser that introduced millions of people to the Internet. After its early success, Netscape was roundly defeated by Microsoft in the so-called browser wars of the 1990s that dominated the Web’s first chapter. Mr. Andreessen appears to want a rematch. Now a prominent Silicon Valley financier, Mr. Andreessen is backing a start-up called RockMelt, staffed with some of his close associates, that is building a new Internet browser, according to people with knowledge of his investment.

The developers at the Mozilla Foundation are looking for volunteers to "test pilot" the Firefox browser as they travel the Web. A "Test Pilot" add-on for Firefox allows a user to try the newest features and enhancements for the browser before other users. The add-on collects data about the behaviour of the test pilots who are involved in the tests.

How to Easily Upgrade your Firefox to 3.5 (and future version) in Ubuntu

Have you ever feel frustrated when Mozilla releases a new build for their software (especially Firefox) and you are still stuck at the previous older version, simply because Ubuntu did not (and do not intend to) add the newer version of software packages to the repository? The truth of fact is, Ubuntu does not update its repositories for newer version of software packages, with the exception of security fixes, until the next release of Ubuntu. For example, the default version of Firefox for Ubuntu Jaunty is Firefox 3.0 and it won’t be upgraded to Firefox 3.5 at least until Ubuntu 9.10. In most cases, especially when it comes to browsers and various Web application, it is always better to upgrade to the newest version due to the new features and security improvement. This is where Ubuntuzilla comes into play.

You can search Google.com from the Linux command line without using a CLI web browser like lynx or Elinks. All you need is the curl and html2text packages installed. Then you issue the following command: curl -A Mozilla http://www.google.com/search?q=Linux |html2text -width 80 where you can replace Linux with another keyword of your choice. The results will be displayed in your console application with a width of 80.

Net Applications Changes Methodology: Windows & Linux Market Share Rises

I have always claimed that the widely used Operating System market share statistics from Net applications were not really accurate when it comes to MacOS and Linux market share. In my opinion there were two factors that prevented an accurate Worldwide market share to be produced: Linux browsers potentially ignoring the counter and improper geographical distribution. The second problem has been fixed and it does impact the Market share numbers significantly.
