Looking at a few Operating Systems

The last few weeks have seen me poking around with a few different operating systems to see how they perform. None of these were particularly in-depth in their nature but brushes with alternatives to what I currently use for much of the time. While I am too sure what exactly has kicked off all of this curiosity, all of the OS’s that I have examined have been of the UNIX/Linux variety. With the inclusion of Unity in the forthcoming Ubuntu “Natty Narwhal” 11.04, I am mindful of the need to be keeping an eye on alternative options should there ever be a need to jump ship. However, a recent brush with an alpha version has reassured me a little. Then there are interesting OS releases too and I recently forgot the Ubuntu password (a silly thing to do, I know) for my Toshiba laptop too so I suppose that a few things are coming together.

It was that latter development that got me looking in amazement at the impressive minimalism of CrunchBang Linux before settling on Lubuntu to see how it did; these were Live CD runs so I tried before I committed to installing. It helped that the latter was based on Ubuntu as its name suggests so I wasted little name in finding my way around the LXDE desktop. By default, everything supplied with the distro is lightweight with Chromium coming in place of Firefox. There’s no sign of OpenOffice.org either with offerings like Abiword coming in its stead. For the sake of familiarity, I started to add the weight of things without reducing the speed of things, it seems. Well, the speedy start-up wasn’t afflicted anyway. Being an Ubuntu clone meant that it didn’t long to add on Firefox using the apt-get command. LibreOffice was downloaded for installation using the dpkg command and it seems much more fleet-footed than its OpenOffice.org counterpart. As if these nefarious actions weren’t enough, I started to poke in the settings to up the number of virtual desktops too. All in all, it never stopped me going against what be termed the intent of the thing. In spite of what Linux User & Developer has had to say, I think the presentation of the LXDE desktop isn’t unpleasant either. In fact, I reckon that I quite like it and the next thing to do is to restore the entry for Windows 7 on the GRUB menu. Well, there’s always somthing that needs doing…

While I may have learned about it after the event, the release of Debian “Squeeze” 6.0 was of interest to me too. Well, I have used it a fair bit in the last few years and retain a soft spot for it. The new release comes on two kernels: GNU/Linux and FreeBSD. Regarding the latter, I did try having a look but it locked up my main home PC when I tried booting it up in a VirtualBox virtual machine. Given that it’s a technical preview anyway, I think it better to leave it mature for a while no matter how fascinating the prospect may be. Or is it VirtualBox 4.x that hasn’t around long enough? Debian’s latest Linux incarnations showed no such inclinations though I found that the CD ISO image that I’d downloaded didn’t give such a complete system when I fired it up after doing the installation. Being someone that knows his way around Linux anyway, it was no problem to add the missing pieces using apt-get though that’d stop it being an option for new users unless the DVD installation yields more complete results. Other than that, it worked well and I lost no time getting to grips with the OS and it’s gained a much fresher feel than version 5.x (“Lenny”). In summary, I look forward to continuing my investigations of the new Debian.

To round up my explorations of different UNIX/Linux operating systems, I have updated my test installations of Ubuntu 11.04. Initial looks at the next Ubuntu release weren’t so encouraging but things are coming along by all accounts. For one thing, Unity can be switched off in favour of the more familiar GNOME desktop that we’ve had for the last few years. The messages that popped up telling you that there’s no 3D graphics support on your machine have been replaced by graceful degradation to the GNOME and that’s no bad thing either. In case it hasn’t been so obvious, I am one of those who needs convincing by the likes of Unity and GNOME Shell so I’ll sit on the fence for a while. After all, there always are alternatives like LXDE if I want to decamp to something else entirely. One of the nice things about Linux is the amount of that we all have; it might be tricky to choose sometimes but it always is good to be able to find a niche somewhere else when someone makes a decision that doesn’t suit you.

You always can install things yourself…

With Linux distributions offering you everything on a plate, there is a temptation to stick with what they offer rather than taking things into your own hands. For example, Debian’s infrequent stable releases and the fact that they don’t seem to change software versions throughout the lifetime of such a release means that things such as browser versions are fixed for the purposes of stability; Lenny has stuck with Firefox 3.06 and called it Iceweasel for some unknown reason. However, I soon got to grabbing a tarball for 3.5 and popped its contents into /opt where the self-contained package worked without a hitch. The same modus operandii was used to get in Eclipse PDT and that applied to Ubuntu too until buttons stopped working, forcing a jumping of ship to Netbeans. Of course, you could make a mess when veering away from what is in a distribution but that should be good enough reason not to get carried away with software additions. With the availability of DEB packages for things like Adobe Reader, RealPlayer, VirtualBox, Google Chrome and Opera, keeping things clean isn’t so hard. Your mileage may vary when it comes to how well things work out for you but I have only ever had the occasional problem anyway.

What reminded me of this was a recent irritation with the OpenOffice package included in Ubuntu 9.10 whereby spell checking wasn’t working. While there were thoughts about is situ fixes like additional dictionary installations, I ended up plumping for what could be called the lazy option: grabbing a tarball full of DEB packages from the OpenOffice website and extracting its contents into /tmp and, once the URE package was in place, installing from there using the command:

dpkg -i o*

To get application shortcuts added to the main menu, it was a matter of diving into the appropriate subfolder and installing from the GNOME desktop extension package. Of course, Ubuntu’s OpenOffice variant was removed as part of all this but, if you wanted to live a little more dangerously, the external installation goes into /opt so there shouldn’t be too much of a conflict anyway. In any case, the DIY route got me the spell checking in OpenOffice Writer that I needed so all was well and another Ubuntu rough edge eradicated from my life, for now anyway.

A certain lack of speed

A little while, I encountered a problem with ImageMagick processing DNG files in Ubuntu 9.04. Not realising that I could solve me own problem by editing a file named delegates.xml, I took to getting a Debian VM to do the legwork for me. That’s where you’ll find all the commands used when helper software is used by ImageMagick to help it on its way. On its own, ImageMagick cannot deal with DNG files so the command line variant of UFRaw (itself a front end for DCRaw) is used to create a PNM file that ImageMagick can handle. The problem a few months back was that the command in delegates.xml wasn’t appropriate for a newer version of UFRaw and I got it into my head that things like this were hard-wired into ImageMagick. Now, I know better and admit my error.

With 9.1o, it seems that the command in delegates.xml has been corrected but another issue had raised its head. UFRaw 0.15, it seems, isn’t the speediest when it comes to creating PNM files and, while my raw file processing script works after a spot of modification to deal with changes in output from the identify command used, it takes far too long to run. GIMP also uses UFRaw so I wonder if the same problem has surfaced there too but it has been noticed by the Debian team and they have a package for version 0.16 of the software in their unstable branch that looks as if it has sorted the speed issue. However, I am seeing that 0.15 is in the testing branch so I’d be tempted to stick with Lenny (5.x) if any successor turns out to have slower DNG file handling with ImageMagick and UFRaw. In my estimation, 0.13 does what I need so why go for a newer release if it turns out ot be slower?
