|DistroWatch Weekly, Issue 367, 16 August 2010
Welcome to this year's 33rd issue of DistroWatch Weekly! It can be difficult trying to count Linux users. Any counting method from downloads, to tracking updates, to monitoring sales continues to leave big question marks on the subject. This week we touch on a new move by Canonical to get a better head count in the OEM market. This week we also shift focus a little, examining an application called Imagination and a helpful command-line tool. This time of the year most of the big-name distros are quiet, but things are still churning in the FOSS community and this week saw releases from Peppermint, Vector, BackTrack, Salix OS, Puppy, Untangle and BlankOn. See our release section to find out the details on these projects. Finally we talk a little about setting up mail server in your own home and the considerations which go with it. As always, happy reading!

Using Some Imagination
At one point or another most of us have either sat through a presentation of slides or talked friends into sitting through our own slide shows. Often it's of pictures taken from a vacation or wedding photos. Regardless of who is subjecting who to the slides, it's usually a long process with little excitement. If you've ever thought it would be nice to mix a little music or audio commentary into a slide show, I'm happy to report there is an open source tool which will do just that. It's called Imagination.
website's own words, "Imagination is a lightweight and simple DVD slide show maker" which is distributed under the GNU GPL. But the program isn't limited to just DVD formatted video, it will also help the user create .ogg and Flash videos, giving the artist greater flexibility and the option to target a wider audience. While there are other tools which will perform similar actions one of the benefits to using Imagination, a creation of Giuseppe Torelli, is that the project tries to keep dependencies to a minimum, simplifying installation.

The Imagination application is split into four basic parts: the menus at the top of the window; slide settings, which are displayed to the right; a picture of the current slide, shown in the centre of the window; and a list of all the slides in the project, which are shown at the bottom of the window. When we first fire up Imagination, everything is blank and empty. So how do we get started?
The first thing we'll want to do is go up to the menu bar and click on the Slide menu and select Import pictures. This will bring up a standard file dialogue which allows us to select multiple images. Generally our next step is to add an audio track to go with our slide show. This is an almost identical process of clicking on the Slide menu and choosing Import music. At this point we see a collection of image thumbnails along the bottom of our screen and a list of audio tracks over on the lower-right. In both cases, these can be moved around, the images by dragging them and the audio tracks have convenient manipulation buttons.
In the top-right corner we find the Slide settings area. This container lists the properties of the currently selected slide. We get to see the slide's dimensions, how long it will stay on the screen, what sort of cenimatic effect will occur at the end of the slide and how long the entire show will take. It's possible to select multiple slides at once by holding the Control key and clicking additional slides and it's easy to remove unwanted slides by highlighting them and choosing Delete from the Slide menu.
Once all the slides are in the right order and have been given the desired properties, we can see what the show will look like by going up to the Slideshow menu and picking Preview. If everything looks correct, we can again return to the Slideshow menu and select Export. The export function makes it easy to save our slide show as a DVD-playable file, an .ogg formatted file or as a Flash video. Saving the file takes a relatively short time and I've found no problems with any of the above formats.
Exporting a slide show

On the one hand this may seem like a very simple process of taking one part images and one part sound and mixing them together to make simple cartoons, presentations and vacation tributes. But, on the other hand, Imagination gives the user a good deal of flexibility. Each slide can be individually adjusted or the entire collection can be changed. Audio tracks and slides can be shuffled around and the output formats are suitable for either family DVD watching or for embedding on a website.
There may be some question as to why I would select such a specifically-focused program to review. It's certainly not that I find the application useful on a daily basis. What I think makes Imagination a point of interest is more wrapped up in its style, rather than its purpose. It has a number of design points which I think make it worthy of recognition. For instance, Imagination does essentially one thing and one thing well. It's not of the family of apps which tries to be an audio player + disc burner + file server + social media interface. It has one specific task and does this task with finesse. The interface is one which I find both intuitive and helpful. Each button comes with a tool tip which clearly states what the button does. The controls are fairly standard and the menus are uncluttered. The user has the option of using menus, a toolbar or keyboard short-cuts to perform most tasks. Things are easy to find and operate in a straight forward manner, really removing any need for a user's manual. A third point in Imagination's favour is that it comes equipped with sane defaults, but almost everything is an option. Background colour, region settings (for DVDs), time delays and visual effects are all adjustable.
What it boils down to is Imagination has one of the nicest graphical user interfaces I've used. The program is clean, user-friendly and the few error messages I've encountered where helpful. This is an application with a small focus which does its job well.
While Imagination is nicely crafted, its target audience is probably small and so I'd like to take a moment to mention another program which I think will be of use to my fellow Linuxers. This second program is called cpulimit and it also does one thing with a straight forward collection of options. Previously, we talked about using the nice and renice commands to adjust a process's priority. This can be handy for making sure your programs are running smoothly, but it doesn't prevent your CPU cycles from being gobbled up. Sometimes it can be useful to put a limit on just how much processing power a process can access at a given time. This might be in an effort to keep your video encoding from interfering with your compiling, or it might be something as simple as keeping your laptop's CPU from getting stuck at 100% and imitating a space heater.
cpulimit program stops a process from using up more than N per cent of your CPU. Let's say I've started up VirtualBox and left its guest operating system doing some long, boring task and I want to make sure it doesn't use more than 25% of my host CPU, I can run
cpulimit -e VirtualBox -l 25
This form of usage will also pick up future processes of the same name and limit their usage as well. Alternatively, if I have more than one instance of the program running, I can specify one process by its PID.
cpulimit -p 10225 -l 25
Used in this way, cpulimit continues to run, even after the process it is throttling dies. To make sure cpulimit exits (and no longer interferes with other processes) after its target terminates, the -z option can be used. For example:
cpulimit -p 10225 -l 25 -z
The cpulimit command should be run with administrator rights. So far I've found it handy for keeping virtual machines, large encoding jobs and backups out of the way while I use my computer's processing power for something else.

Counting Ubuntu OEM installs, FreeBSD conferences, Patching a running kernel the easy way
There is always a bit of a question mark attached to the number of Linux users in the world. Getting an accurate count can be difficult because people in the Linux community tend to move around a bit (from distro to distro) and also tend to be a private group. Last week
Canonical introduced a new way to get a head count. Future OEM installs of Ubuntu will come with a package called canonical-census that will send a daily ping to a Canonical server. The software "does not send any user specific data; it only transmits the operating system version (/var/lib/ubuntu_dist_channel), the machine product name, and a counter how many pings were sent." This should tell Canonical how many OEM installs are being sold and how long the systems continue to run Ubuntu.

Do you want to travel the world, meet like-minded people, shake a daemon's hand? If so, you will be happy to read about upcoming events, such as
KyivBSD Con, BSD-Day, EuroBSDCon and others. Each of these events is a great opportunity for users and developers to mingle, share ideas and talk about BSD. Some of these events have registration, so check them out now!

The concept, and indeed the practise, of patching a running Linux kernel isn't new. However, the idea of making adjustments to the heart of an operating system while it is still running sounds scary and complicated. IBM has a
well-written article on their website explaining why live kernel patching can be useful and how to go about performing the task. The steps are clearly laid out and it should be beneficial to anyone concerned with maintaining their uptime.

One of the benefits to using open source software is that a wide range of people can examine and, potentially, fix problems in the code. The Chromium web browser recently demonstrated this when a regression inadvertently made its way into a build, causing Chromium to send data back to Google. The unintended behaviour was
quickly discovered, the code located and a bug filed.
In other software news, the KDE project recently released version 4.5 of the popular desktop environment. To mark the occasion TechWorld is running a short
interview with Sebastian Kugler, a developer and spokesperson for the project. This release appears to focus mostly on bug fixes and performance improvements, bringing some polish to the KDE4 series.

If you've looked at Peppermint OS One and Peppermint Ice, you might have wondered what their relationship is and what separates them. Is one an upgrade, a re-spin, a fork? Which one is better suited to your needs? Jim Lynch
examined the two Peppermints and gives us some answers. A good read for people curious about the light, web-focused distribution.

Rumours have been circulating over the death of OpenSolaris for several months now and Oracles official stance of silence has only added fuel to the fire. This week a document, purported to be a
leaked internal Oracle memo, touches on the future of OpenSolaris, or its lack of a future. If this document is real, it spells can end to the OpenSolaris project.
|Questions and Answers (by Jesse Smith)
Virtual Post Office
Wants-to-receive-mail-at-home asks: I'd like to setup my own e-mail server and get my mail off the cloud. Any tips on setting up my own home-brew e-mail server?
Setting up your own private e-mail server can be an educational and rewarding experience. Good for you on taking the initiative to try this! There are a few things you might want to consider before you begin. The big one being: what do you hope to achieve above and beyond what your existing cloud-based service is providing? For instance, some people create private e-mail servers to gain privacy and prevent Google (or other big corporations) from reading their mail. The problem with this thinking is most e-mail is still sent in plain-text and it will pass through various other networks like so many pages of an open book. Also, copies of your messages will be stored on the other correspondent's e-mail server, which may be Gmail or Yahoo Mail, etc.
There are other considerations too. For example, you probably expect your cloud-based e-mail provider to be on 24 hours a day, every day. You probably want the same or better attachment size allowances, similar or better storage space, as good or better security, and as little or less spam getting through. A question to ponder is: can you provide these things to yourself as well as your existing provider? These are some points to keep in the back of your mind while you're putting together your new server. Being independent has its perks, but it also requires a bit of work.
I don't want to go into deep details on actually setting up the server here as each person will have slightly different preferences as to server type, operating system, spam filter and anti-virus, but I will point you to a few tutorials. This first one is for people on the Ubuntu family of systems and covers most of the basics. Here is another document for installing a mail server on an Arch Linux system. For FreeBSD fans, you can consult the project's Handbook as a place to get started. And for folks who like to learn from books, I suggest picking up a copy of Linux E-mail, which talks about setting up an e-mail server for a small network.
One more thing to keep in mind is running any sort of service on your home machine opens a potential avenue of attack against your computer. Be sure to keep your system locked down and up-to-date with security patches.

Introduction to nginx
This FREE 69-page eBook introduces you to the magic of nginx, an open-source HTTP and reverse proxy server, a mail proxy server, load balancer and HTTP cache.
