Things I do not like about Ubuntu LTS 10.04

The new Ubuntu 10.04 release is a great release and it is really a task to find things you dislike. Anyhow no operating system is perfect and this one also has some flaws. But now itself I am telling you that this is from my point of view and my dislikes may not be your dislikes!!!!

• The new themes

Well the first thing I dislike about the Ubuntu 10.04 LTS is its new themes. These new themes do nothing but set back the looks of the previous versions. Ok, these themes must be on account of the GNOME 3.0 but the default theme selected is, according to my opinion, is a great mistake. This is also coming on the heels of the rumors of the possible inclusion of RGB support in the GTK widgets, which would have enabled real transparency in all widget sets. This did not happen (and is still not happening). My concern is that most new users will install 10.04 and have trouble getting beyond the default themes.

Things I love about Ubuntu 10.04 LTS Lucid Lynx

The things I Love and Hate about the new Ubuntu 10.0.4 Lucid Lynx.

• GNOME 2.30

This is the final 2.x release before the major upgrade to 3. This will be the last time you will see the GNOME 2.X in Ubuntu flavor. For me it is fantastic. GNOME 3 will be a graceful successor to GNOME 2.x. In fact, I can promise that GNOME 3 will succeed where KDE 4 failed — in being a useful desktop upgrade right out of the starting gate.

• HAL begone

Ubuntu 10.04 has done away with HAL (Hardware Abstraction Layer) during the boot process. This means that 10-second boot time has finally arrived. Hence the 10 second booting can be achieved in a charming way. The removal of HAL also drastically speeds up resume-from-suspend times for those of you in laptop land.

The system-config-firewall

secuThe firewall rules in the kernel can be configured by using iptables since 2.4 kernel. There are number of tools for configuring the firewall like command line tool, Shorewall, and a number of other GUIs. The default firewall configuration tool in Fedora systems is called “Firewall Configuration”, which can be accessed from Systemà Administration à Firewall in GNOME or from command line via, “system-config-firewall”.


This GUI allows you to set which services are allowed to be accessed via the Internet using a very simple interface. It defines a set of trusted services to be configured. To allow access, you simply need to check the box next to the entry. Each entry lists the service name, the port and protocol, and any additional iptables modules it uses. So if you wanted to allow Samba access to the system, you would check off the box next to the Samba and Samba Client service as in figure below.

The Oracle effect on Sun Microsystem VARs

The new policies introduced by Oracle in terms of “Oracle hardware support” for Sun servers are creating tensions among Sun VARs. The new policies from Oracle are “sinking” the customers as told by some VARs.

One Sun Microsystems systems integrator commented that it was getting pretty bad. The maintenance renewals and services are 3 times what they had in terms of price. Oracle also revoked the prepaid discounts and other flexibilities. Now Oracle charges 12% of the Sun hardware cost per year but in the past it depended on the hardware type and the multiplier was roughly 5% 0r 6%.

"Before this year, a customer buying a Sun 5240 server got three years of support for $3,800, including a discount for paying for the three years at once," this partner said. "That same box will now cost $7,699 to support for three years, a customer told.

Landscape 1.5: Ubuntu Server Monitoring & Management Tool

Canonical has released its new server monitoring and management tool Landscape with its Ubuntu 10.04 LTS (Long Term Support) edition. The application is meant to make Ubuntu sever monitoring, management and package provisioning easy.

Ease of use is the main advantage of Ubuntu based distributions. However not much solutions were available to manage and monitor a group of Ubuntu servers simultaneously. Finally Canonical developed its own solution and that is “Landscape”. And with the release of their new distribution Ubuntu server 10.04 LTS Lucid Lynx, they have updated the older version to Landscape 1.5. The new version Landscape 1.5 is available as an on-site server and an online service from Canonical. Landscape is a simple and easy to use web based application that provides powerful automated system management capabilities such as management, monitoring and provisioning of packages across multiple machines, thereby lowering your per-systems cost of management and administration.

Ubuntu 10.04 LTS will also spot a larger network of open-source and proprietary application providers certifying their applications on Ubuntu Server Edition than ever before. About 100 organizations have signaled their intent to certify applications on the platform, including Alfresco, Ingres, IBM, VMware, Zimbra, Yahoo! and many others with more expected to follow post-launch. Dell has announced its intention to support Ubuntu 10.04 LTS Server Edition and will offer Ubuntu Enterprise Cloud as an option on its PowerEdge-C product line - servers specifically designed for building cloud environments.

RedHat Enterprise Linux 6 Beta released.

Good news for all the RedHat enthusiasts: Red Hat Enterprise Edition 6 Beta has released. This beta release is the first step forward to the next major release of the Red Hat Enterprise Edition platform 6. Red Hat Enterprise Linux is expected to address the modern IT requirements and diminish the gap between virtual, physical and cloud computing. This first beta release of the RHEL 6 features updated core technology from the kernel to the application infrastructure to the development tool chain. RHEL 6 is going to meet the needs of the coming generations of hardware and software technologies.

The major themes of the release include pervasive virtualization, improved scalability and availability, increased power efficiency, and delivery of some of the latest software technologies. Now I will describe the highlights and noteworthy improvements in this RHEL 6 beta release.

• Comprehensive power management capabilities:

RedHat Enterprise Linux 6 is more focused on power consumption by improving the 'Time-keeping' within the kernel. It helps to transit the processors which don't have active tasks to idle state frequently. The result is cooler CPUs and greater power savings. The new monitoring tools like 'powertop' and tuning tools like 'tuned' are also worth mentioning.
