Google Chrome in Ubuntu keeps detecting network change

Recently I had problem with my Ubuntu, Whenever I tried to open a website my Chromium told me that a Network Change has been detected and after 1-2 reload that sites would load and sometimes failed to load fully.

After looking up for that problem, I found out many other people had same problem and it has something to do with “avahi-daemon”.


According to the links I found in Ubuntu forums, this problem comes from IPv6 in Ubuntu and disabling that service will fix it, I tried it and it worked:

# create the long-life config file
echo "net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee /etc/sysctl.d/99-my-disable-ipv6.conf

# ask the system to use it
sudo service procps reload

# check the result
cat /proc/sys/net/ipv6/conf/all/disable_ipv6

Security vulnerability in NVIDIA’s proprietary Linux drivers fixed

NVIDIA_logo200The H-Online: A new version of NVIDIA’s proprietary UNIX graphics drivers for Linux, Solaris and FreeBSD fixes a security vulnerability (CVE-2012-0946) that allowed attackers to read and write arbitrary system memory in order to, for example, obtain root privileges. To take advantage of the vulnerability, an attacker must have access permission for some device files – which, for systems with these drivers, is typically the case for users who can launch a graphical interface as 3D acceleration and some other features cannot be used otherwise.

Version 295.40 of the driver corrects this problem; for older drivers whose version numbers start with 195, 256 to 285, or 290 to 295, NVIDIA has made patches available that change the vulnerable part of the kernel module belonging to the driver. Users who update the driver with this patch and use the CUDA debugger will also need to update the CUDA library before the debugger can work again.

NVIDIA has categorized the security hole as “high risk” and recommends that users update to the new version if they use the drivers with GeForce 8, G80 Quadro graphics cards, or newer models from those lines. The company has not confirmed whether the problem also exists for older graphics card models or legacy drivers (such as the 173 line).

GNOME Developers Attack Canonical’s Ubuntu Decision

Many Ubuntu users will undoubtedly have strong opinions on Canonical’s recent proposal to replace the GNOME desktop with Unity in the Ubuntu 11.04 release.  But for the programmers behind GNOME, one of the open-source community’s most important projects, the announcement might prove to be even more upsetting.  Jon McCann, lead designer for GNOME Shell, recently shared his thoughts on this topic with us–and he was none too charitable in his comments on Canonical.  Read on for details.

GNOME Shell, of course, is the new desktop interface on which GNOME developers are currently hard at work as the next big step for one of the Linux world’s most popular desktop environments.  GNOME Shell introduces a number of innovative interface concepts that, if successful, could truly redefine the way users interact with their operating system.

Unity, meanwhile, is an interface developed by Canonical that borrows many of its ideas from GNOME Shell.  Canonical began work on Unity last spring, and introduced it as the default interface for Ubuntu Netbook Edition in the Ubuntu 10.10 release, which debuted a few weeks ago.

But the big news came last Monday at the Ubuntu Developer Summit in Florida, where Mark Shuttleworth suggested that the next Ubuntu release, April 2011′s Natty Narwhal, should adopt Unity as the interface for Ubuntu Desktop Edition as well as the netbook version, which would entail major changes for many users–not to mention upstream developers, who might have to make big changes if they want their code to remain consonant with Unity.

Canonical’s Leap Off?

Ubuntu developer Jono Bacon was quick to point out that Unity will still depend heavily on GNOME’s software stack, even if the interface itself break away from GNOME.  That may be true, but GNOME developer Jon McCann nonetheless views this move as a fundamental break between Ubuntu and GNOME.

Not that McCann was surprised.  “Canonical has been pulling away from the GNOME project for about two years,” he declared.  “So, this was inevitable.  I suspect that the timing probably has a lot to do with Mark’s jealousy of the recent OS X Tiger announcement.”

Nor did McCann question the validity of Canonical’s decision.  The organization has been working “to differentiate and become a profitable company” for some time now, he said, and the break with GNOME seems to fit into that equation.

But McCann is doubtful that Canonical’s new strategy will pay off for the company.  Questioning the feasibility of getting Unity ready for Ubuntu Desktop Edition by April, McCann noted that Unity’s principal designer just left Canonical, and that it will be difficult for the company to forge a completely independent path after having relied centrally on upstream contributions for most of its existence.  “When you have been standing on the shoulders of giants for so long it is a bold move to leap off and hope you can fly on your own,” McCann asserted.

Despite his lack of optimism for Canonical’s strategy, however, McCann views the break as a change that can make GNOME stronger by lessening its dependence on downstream developers.  “We should probably stop relying on distributions to deliver our value anyway.  I think there is a valid comparison to how musicians are starting to realize they don’t need to sell their soul to record companies and corporate radio stations to reach their audience.”

And insofar as the Unity plans might represent a rift between Ubuntu and GNOME–or, indeed, between Ubuntu and much of the rest of the open-source ecosystem–McCann does not rule out the possibility of a reconciliation in the future, concluding, “I am sure that if they don’t succeed we will welcome them back like the prodigal son.”

Russian government decides to develop Windows alternative

The Russian government is no longer comfortable being dependent on the Windows operating system, and has thus decided to create its own flavor of Linux for internal use. 150 million rubles (€3.55 million or nearly $4.89 million) has been put aside for the project. That’s a huge amount of money to invest into something that isn’t certain (what if Russia gives up and goes back to using Windows 7?).

“We will become independent of Windows … but it risks becoming an unthinking implantation of Linux [that was probably supposed to be translated as “implementation”],” Russian deputy and computer expert Ilia Ponomarev told the AFP. Nevertheless, he admitted that it will be difficult to create and implement an operating system secure enough for government use, conceding that “the devil is in the details.” Those details will be hashed out during a December meeting headed by Vice Prime Minister Sergei Ivanov.

Until the project comes to fruition and Russia actually declares its solution superior to Windows, this won’t be a big deal. Even then though, we doubt Microsoft will be particularly worried. The software giant will undoubtedly be unhappy for losing some business, but it won’t be a huge blow.


Desktop Linux: The Dream Is Dead

linuxThe author of this article seems to think Linux in the desktop is dead, with so many missed opportunities, especially during the failure of Windows Vista, they will never break into the market now that Win 7 is so successful.

In some ways I agree, but personally, I never thought Linux even had a chance with the average user on a home system. Being in IT, like most peeps in my field, I have become the “help desk” for family and friends; I really do not think the average user is ready for it. Add in the lack of applications and games that are available, it really did not stand a chance. I design and write software, the development costs these days are huge, and the money peeps want a good ROI to out weigh the risks, developing from scratch or even porting an existing app is just too risky.

On the business end, ever since the SOHO fiasco where they were threatening to sue any and all companies that were using Linux, many of my large clients, including a major international bank, dropped Linux as a server operating system faster then you could say Penguin. I remember sitting in a systems and architectural conference call at the bank, they had just spent the past month or two doing a risk assessment of the chances of being sued by SOHO; they considered it to be high as their Linux supplier was IBM. They then presented their operating costs of the data centers running Linux and data centers running Windows over the past few years, the costs and risks were lower for Windows; within 6 months all the servers were Windows.

On the other hand, the new Apple products are Linux based and are very successful, so with the right backing, the money to support and write applications, Linux could everything their supporters want it to be and I wish them luck.
