Improve Battery Life with Laptop Mode Tools 1.65
|
||||
================================================================================
|
||||
|
||||
|
||||
Laptop Mode Tools, a power-saving package for Linux systems that allows users to extend the battery life of their laptop in several ways, is now at version 1.65.
|
||||
|
||||
The Laptop Mode Tools releases are few and far in between, but the developers have made some very interesting changes and improvements in this latest version, although the update is not as consistent as would like it to be.
|
||||
|
||||
According to the changelog, a grep error on missing $device/uevent has been fixed, sysfs/enabled has been replaced by “ip link down”, iwlwifi support has been added, the Runtime Power Managemet Framework is now a lot more robust, and the module usb-autosuspend has been deprecated.
|
||||
|
||||
Also, when the laptop is resuming, Laptop Mode Tools is run in force initialization mode, a module for the Intel PState driver has been added, and the suspend/hibernate interface has been implemented.
|
||||
|
||||
Users must not change the autonegotiation settings. Fiddling with auto-negotiation settings can cause more problems and the standards expect them to be always on. Also, pay attention to what every function does because you might do more damage than good.
|
||||
|
||||
Check the official [announcement][1] for more details about this released.

|
||||
================================================================================
|
||||
|
||||
|
||||
In conjunction with the recent OpenStack Summit in Atlanta, Red Hat had confirmed many new OpenStack-centric initiatives, one of which was that the company [is collaborating][1] with eNovance, a leader in the open source cloud computing market, tto drive Network Functions Virtualization (NFV) and telecommunications features into OpenStack. Now, Red Hat has [announced][2] that it will acquire eNovance for about 70 million euros, or $95 million, in cash and stock.
|
||||
|
||||
eNovance is an important player on the OpenStack scene, and is especially known for its work with telecommunications companies. eNovance helps service providers and large-scale private enterprises build and deploy cloud infrastructures quickly and cost effectively, and will create new lines of business for Red Hat.
|
||||
As noted by IDC analysts Laura DuBois and Ashish Nadkarni in their recent recap of the spring 2014 OpenStack Summit, "Integrators such as eNovance will continue to assist cloud service providers and enterprises in building large OpenStack clouds. ... The future for OpenStack is looking very bright."
|
||||
|
||||
eNovance is one of the top 10 contributors to the upstream OpenStack project, and is the only European Gold Member company of the OpenStack Foundation. The company has more than 150 global customers, including Alcatel-Lucent, AXA, Cisco, Cloudwatt, and Ericsson. The company has offices in Paris; Montreal; and Bangalore, India.
|
||||
|
||||
Red Hat and eNovance [first partnered in 2013][3] to deliver OpenStack implementation and integration services to joint customers, based on the Red Hat Enterprise Linux OpenStack Platform. At OpenStack Summit in May, the two companies announced an [expanded collaboration][4] to drive Network Functions Virtualization (NFV) and telecommunications innovations into OpenStack, aimed at delivering the industry’s most complete, carrier-grade telecommunications offering based on Linux, Kernel-based Virtual Machine (KVM), and OpenStack.
|
||||
|
||||
Raphaël Ferreira, co-founder & chief executive officer, eNovance, said in a statement:
|
||||
|
||||
> “eNovance, like Red Hat, understands the transformative power OpenStack can have on the enterprise market when it is both deployed and integrated in the right fashion. We are excited to become part of Red Hat, a company that not only offers one of the best-in-class OpenStack distributions on the market today, but also which shares our common belief that OpenStack is best deployed and integrated in a continuous and seamless manner."

Red Hat designs RHEL for a decade-long run
|
||||
================================================================================
|
||||
> The newly released RHEL 7 includes Docker containers and the new terabyte-scaled XFS file system
|
||||
|
||||
IDG News Service - Knowing how system administrators enjoy continuity, Red Hat has designed the latest release of its flagship Linux distribution to be run, with support, until 2024.
|
||||
|
||||
Red Hat Enterprise Linux 7 (RHEL 7), the completed version of which was shipped Tuesday, also features a number of new technologies that the company sees as instrumental for the next decade, including the Docker Linux Container system and the advanced XFS file system.
|
||||
|
||||
"XFS opens the door for a new class of business analytics, big data and data analytics," said Mark Coggin, Red Hat senior director of product marketing.
|
||||
|
||||
The last major update to RHEL, RHEL 6, was released in November 2010. Since then, server software has been used in an increasingly wide variety of operational scenarios, including providing the basis for bare metal servers, virtual machines, IaaS (infrastructure-as-a-service) and PaaS (platform-as-a-service) cloud packages.
|
||||
|
||||
Red Hat will support RHEL 7 with bug fixes and commercial support for up to 10 years. The company generally releases a major version of RHEL every three years.
|
||||
|
||||
In contrast, Canonical's Ubuntu LTS (long-term support) distributions are supported for five years. Suse Enterprise Linux [is also supported][1], in most aspects, for up to 10 years,
|
||||
|
||||
This is the first edition to include Docker, a container technology [that could act as a nimbler replacement][2] to full virtual machines used in cloud operations. Docker provides a way to package an application in a virtual container so that it can be run across different Linux servers.
|
||||
|
||||
Red Hat expects that containers will be widely deployed over the next few years as a way to package and run applications, thanks to their portable nature.
|
||||
|
||||
"Customers have told us they are looking for a lighter weight version of developing applications. The applications themselves don't need a full operating system or a virtual machine," Coggin said. The system calls are answered by the server's OS and the container includes only the necessary support libraries and the application. "We only put into that container what we need," he said.
|
||||
|
||||
Containers are also easier to maintain because users don't have to worry about updating or patching the full OS within a virtual machine, Coggin said.
|
||||
|
||||
Red Hat is also planning a special stripped-down release of RHEL, now code-named RHEL Atomic, which will be a distribution for just running containers. Containers that run on the regular RHEL can easily be transferred to RHEL Atomic, once that OS is available. They will also run on Red Hat OpenShift PaaS.
|
||||
|
||||
Red Hat is also supporting Docker through its switch in RHEL 7 to the systemd process manager, replacing Linux's long used init process manager. Systemd "gives the administrator a lot of additional flexibility in managing the underlying processes inside of RHEL. It also has a tie back to the container initiative and is very integral to the way the processes are stood up and managed in containers," Coggin said.
|
||||
|
||||
Red Hat has switched the default file system in RHEL 7 to XFS, which is able to keep track of up to 500TBs on a single partition. The previous default file system, ext4, was only able to support 50TBs. Ext4 is still available as an option, as well as another of other file systems such as GFS2 and Btrfs (under technology preview).
|
||||
|
||||
Red Hat has added greater interoperability with the Microsoft Windows environment. Organizations can now use Microsoft Active Directory to securely authenticate users on Red Hat systems. Tools are also included in RHEL 7 to offer Red Hat credentials for Windows servers.
|
||||
|
||||
"Customers have thousands of Windows servers and thousands of RHEL servers, and they to need ways to integrate the two," Coggin said.
|
||||
|
||||
The installation process has been sped up as well, thanks to an update to the Anaconda installer, which now allows administrators to preselect server configurations on the start of the installation process. The inclusion of the industry standard OpenLMI (Open Linux Management Infrastructure), which allows the administrator to manage services at a granular level through a standardized API (application programming interface).
|
||||
|
||||
"OpenLMI is another important way of improving stability and efficiency by helping to manage systems better," Coggin said.

How To Remove Drive Icons From Unity Launcher In Ubuntu 14.04 [Beginner Tips]
|
||||
================================================================================
|
||||
**A question sent by a reader**: How can I remove those drive icons from Unity Launcher in Ubuntu 14.04? I never use it and it eats up space in the launcher.
|
||||
|
||||
By default all the partition on your system is visible in Unity launcher, no matter if it is mounted or not. And in fact it might be crowding up the Unity Launcher space. Absolute beginners to Ubuntu may have to struggle a bit pondering over how to remove the drive icons from launcher but the solution to this problem is very easy.
|
||||
|
||||
To **remove the drive icons permanently from Unity Launcher in Ubuntu 14.04**, right click on the drive and select Unlock from Launcher.
|
||||
|
||||
|
||||
|
||||
That’s it. You don’t need to anything else. You won’t see the drive icons again in Unity Launcher, even if it is mounted. I hope it helps you. Feel free to ask if you have questions.
