Patent rights belonged to the originator of an idea or concept and were only granted — again, for a limited time — after strenuous tests of originality and appropriateness had been met.
They would only be conferred on inventions that were entirely original, were not obvious, and had the potential to radically transform the way things were done. Over the last 30 years the bar has dropped, and patents are issued for trivial and obvious inventions.
Patents can be disputed, but the cost of doing so is prohibitive. But instead, the newly formed SCO Group decided to take the plunge into the world of litigation. They have nothing to lose and everything to gain. In many cases, the cost of contesting a patent, searching for prior art and the recruitment of lawyers, is prohibitive and a distraction, so a settlement is made without recourse to the law and the validity of the patent is never contested.
Owning your own patents as a bargaining chip is no defence against a troll. Jon lives in Cambridge, Massachusetts, and works for a large enterprise Linux vendor. He publishes a daily Linux kernel mailing list summary at kernelpodcast. This will allow Linux systems to fully disable the periodic housekeeping timer tick under special circumstances.
The timer tick is typically used by the Linux kernel to cause special kernel code to run at a certain interval, although the kernel already supports the notion of disabling the timer when a CPU is idle. Therefore, it is possible for a system administrator or programmer to carefully manage a given CPU perhaps using cgroups such that it will not experience the added latency of a periodic timer interrupt caveat: it will still run once per second, but not , times per second as is traditional.
Memory pressure occurs frequently as modern systems have huge amounts of memory, but also large numbers of in-memory caches that will grow to consume all of the space available. The kernel has visibility into — and control of — its own internal caches, which it will grow and shrink as needed, but it traditionally has had no idea how much memory applications were using for caches that could be voluntarily relinquished as necessary. The merge window for 3.
He subsequently announced several additional RCs, with the fourth being the most recent as we went to press there are typically seven or eight total, one per week, during a kernel release. In announcing 3.
But it could certainly be smaller still boo! But it actually means very little, especially on modern computers. Although this means nothing in practice, it did result in some confused users, and further complaints and protests, usually by those who were unaware that BogoMIPs in fact means nothing useful.
This is a special annotation, used to mark a function as being of use only during CPU init and safe to remove from kernel memory afterward to free up kernel memory.
His mail triggered an interesting conversation between Rik van Riel and Peter Zjilstra, and some suggestions on improvements. Finally, several proposals for Linux Plumbers Conf www. Readers will perhaps be aware that virtual machines leverage hardware and software capabilities of modern microprocessors in order to provide VMs with slices of CPU time, much as regular applications are multitasked rapidly to create the illusion of concurrently executing programs.
In this case, there is no need for the vCPU to actually spin: that vCPU can be descheduled in favour of another until the spinlock is released. Jiannan is among those who are researching further optimisations, such as ticket spinlocks and the like.
Linux Mint 15 then is a preview of a mature, more independent Mint that will allow for great innovation over the coming year. Cinnamon 1. MATE has received an overhaul, with a lot of background packages and core libraries replaced and updated.
He loves to experiment with computing 20 www. While there were some initial hiccups that required a Firstly, the new Software Sources manager is designed for distributions that derive themselves from others, like Mint is from Ubuntu, and also has a simple speed test for repositories. However, the images themselves are not much bigger than a CD, clocking in at around MB. Installation is quick and painless if you want it to be, and more advanced if you have special needs for your system.
This default greeter is part of the new HTML5 theming, which allows for animated themes using the web standard. There are already a few available to try out, and more online created by users and web designers alike that can feel right at home with the familiar code.
MATE 1. A lot of the work in MATE 1. By default, you have two panels, with the top one having separate drop-down menus for applications, places on the computer and system settings. New in MATE 1. The live image boots straight into the desktop, with no boot options to either start the install straight away, or for any alternate boot methods. A new digital clock resides on the desktop as one of the new desklets, similar to Android widgets.
These interactive desktop spots are easily manipulated, so you can move, remove or add more of them easily to suit your preference. The interface is straightforward and offers just the right balance of information and user-friendliness. Running through the installation setup process can be very quick if the default settings are all to your liking. Login details are arranged like a HUD, with usernames on the edge and password entry on the bottom.
A robo-Tux keeps a watchful eye over the situation. After about seven or so minutes of copying and installing, the process is complete, and Linux Mint asks us to restart. From here you can continue to use the live distro if you have any ongoing work. An analogue clock on one corner and spinning buttons around the interface are reminiscent of a much simpler time in technology, without being too confusing. Now with searching within categories for a more focused experience, the Software Manager is a great part of Linux Mint Desklets are a new addition to Linux Mint 15 and Cinnamon, bringing the widget-style desktop features from other DEs and Android to Mint.
All the customisation options for both the Cinnamon environment and the distro itself have been merged under one settings application — before, the Mint Menu would System Settings and Cinnamon Settings now all come under one united graphical application.
It also seems to run with fairly low power requirements. Testing it on a laptop, we found it gave us up to 30 per cent extra battery life than Ubuntu running Unity would doing similar tasks. We ask Lefebvre whether or not there were still features they had been wanting to add. Most of it was done by [Webster]. So No need for titles No hierarchy, no problem for the Linux Mint development team As part of any interview, we like to make sure we have names and titles for the people we speak to and feature in the article.
Some of the devs are further broken down into different sections, the more important they get. In Mint, more and more modules were given to cinnamon-settings, and more and more modules were hidden in gnomecontrol-center as they integrated better with Shell and less with Cinnamon.
Basically, in 2. This is both something we want and something we have to do. Our relationship is fantastic and we even collaborate and help each other outside of the scope of MATE. They were doing great and shared the same vision so we decided to back them as much as we could. Cinnarch and Manjaro have both dropped Cinnamon.
That means D-Bus interfaces, settings etc. They came to us in panic, at the last moment. In Cinnamon 2. With the push for 2. If, however, I do not love what I see, I can cancel at any time.

It gives some useful information such as size and system attributes Grow your disks like a true master and never reformat and restore your drive again Stuart Burns is an Resize your disks on the fly with LVM Advisor experienced Linux and virtualisation specialist for a Fortune company and enjoys writing about Linux Resources VirtualBox: www.
Linux has the ability to extend or shrink logical partitions across spare space or even across additional disks. This guide walks you through the why and the how of resizing your disks. We will be creating an additional new LVMbased partition on our virtual CentOS server, as well as the underlying structures that are called physical volumes PVs and volume groups VGs that make this awesome technology possible.
The best way to think about LVM setups is that they are like a layered sponge cake. On the bottom layer we have the physical volumes: the hard disks. This means that a partition can be bigger than a single disk. Also, when you want to expand a disk, as long as you have space in your volume group, you can. To do this we use a command called pvcreate.
This effectively prepares and marks the disk as an LVM disk. To do this, use the command: Essentially LVM separates the logical volumes from the physical disks with a glue in between called Volume Groups or VGs for short. Firstly, you may actually be using LVM without realising it! Most newer distros use LVM when they do their install. To see if you are, just open a root console and type lvs. If you see something like that shown in the picture above, then you are already using LVM.
In our example we will be creating a new logical volume from scratch, but the same principles around resizing and reducing still apply. In our example, sdb is our new disk. Accept the geometry the machine suggests by pressing 04 03 Preparing the bottom layer of our LVM cake: physical volumes Once we have set up the partition, we need to identify it as an LVM device. Each of these is like a chunk of storage that you can slice into one or several logical volumes. The difference is that you can expand and reduce disks within the volume group.
You can make the volume as small or large as you like, given a big enough volume group. We are using the entire volume group, rather than just a small portion of it. Now we can create a logical disk on top of it. There is a command called resizefs that we can use. Now that the partition is prepared, we can add it into the volume group we just created.
To do this we use the vgextend command, as shown below. Below is a simple example to just expand our VG with a 1GB partition. Not only that but also not all systems, especially servers have a GUI installed. This will install the graphical LVM tool. To try it out, lets try with a basic server with an additional 1 GB drive. Now this is where things get interesting. This could be a 60GB or GB disk.
We just chose the 1GB as an example. This is where we see the joy of LVM. We can expand our volume over the new disk and make our volume bigger! To do so, repeat the process we performed earlier to prepare the disks with fdisk and pvcreate. Start by loading the LVM tool. If you look to the lefthand side of the application you will see Volume Groups, Unallocated Volumes, and Uninitialized Entities. It shows the volume groups that we work with, volumes and raw devices that are not members of volume groups.
Doing it this way can be very useful in that it will set up the disk label and such automatically, so no terminal and fdisk are required. Before you add your unused partition, you will need to initialise the partition, as you can see. Do this by clicking Initalize Entity. This is equivalent to preparing a volume using fdisk and pvcreate as we did before. At this point you will see the make-up of your new volume group, the physical disks and the logical make-up.
Once this has completed, you will see that the disk has moved from Uninitialized to Unallocated — so, basically, it is prepped to add to our volume group. You will also notice that if you click on the unallocated volumes you will get a group of buttons below, each stating its purpose. You could, if you wanted, create a new volume group with this disk — or, as we did before, add the disk to an existing volume.
Remember, a VG is just a chunk of space that you can split up as you wish; so when you are presented with the sizing screen, carve up that space as you wish.
When creating a new volume group, you will get a selection, as shown below. Hit the Create Logical Volume button. Now you can specify the logical disks.
Give it a good name. Again for LV properties, just go with the defaults. Size is easy enough and obvious enough. If you want to use the entire disk most people do , click Use Remaining. Unless you have a compelling reason to change to it, leave the default selection as it is.

And turned off. Otherwise, you will be open to the potential of abuse. And with the ubiquity of wireless networks, these prove to be a very tempting and rather large target for the bad guys.
One of the better ways to secure your systems is to try to break them through penetration testing. The usual way in which this is done is by using either a desktop machine or laptop connected to the network. This means that you are tied down to a desk. But sometimes, being able to rove around is helpful.
To this end, having an Android tablet or smartphone handy will let you test any wireless network that you have access to. If your Android device is rooted, you can install an app called dSploit. This app will give you all of the tools you will need to do a thorough test of your system defences. You should be able to download a copy directly from whatever browser you use on your device.
