iPod, identified

Plug in an iPod to a PC running Ubuntu and it will recognise what it has got. That act mounts the player as a hard drive and fires up the Rhythmbox Music Player. The usual file transfer capabilities are available and it does something that was thwarted partially by iTunes when I last tried it: transferring files from your iPod to your PC. Only music bought from the iTunes store can copied from the player back to the PC. Unsurprisingly, you cannot update the iPod’s firmware or anything like that. To do such things, you need the iTunes player and that means having either Windows or OS X. While I do wonder if it can’t be that hard to port the OS X version to Linux since they both share UNIX roots, it’s over to the Windows VM for me on this one for now.

Connecting to Host USB Devices from VMware

However, while VMware on Windows will happily pick up USB devices as they are connected so long as the VM is in focus, the behaviour on Linux seems to be different. As shown above, you have to go to the VM menu and potter down the chain (Removable Devices > USB Devices) to make the device of interest accessible. Dialogue boxes asking you if you want to disconnect the device from the host operating system will appear and the process may be unsubtle as you progress with it. In fact, Ubuntu was delivering warning messages about how its iPod connection got lost; it would have been wise to unmount the thing in the first place. Accessing USB devices like this opens up other possibilities: using Windows for scanning and for printing digital images.

Returning to the iPod story, Windows will see it once it has been made available and iTunes can access it accordingly. Then, you are free to update the gadget’s firmware or manage the music stored on it, if you prefer.

Why I’ll be keeping Windows close to hand for a while to come

Even though I have moved to Linux and it has been fulfilling nearly all of my home computing needs, I do and plan to continue to retain access to Windows courtesy of virtualisation technology. Keeping current with the world of the ever pervasive Windows is one motivation but there are others. In fact, now that Windows is more of a sideline, I may even get my hands on Vista at some point to take a further in-depth look at it, hopefully without having to suffer the consequences of my curiosity.

Talking of other reasons for hanging onto Windows, listening to music secured by DRM does come to mind. DRM is seen in a negative light by many in the open source world so Linux remains unencumbered by the beast. That isn’t necessarily a bad thing and the whole furore about Vista and DRM earlier this year had me wondering about a Linux future. However, I have been known to buy music from iTunes and would like to continue doing so. WINE might be one way to achieve this but retaining Windows seems a sounder option. That way, I am saved from having to convert my protected music files into either Ogg Vorbis or FLAC; the latter involves a lossless compression unlike the former so the files are bigger with the additional quality that an audiophile would seek. MP3 is another option but there are those in the Linux world who frown upon anything patented. That makes getting MP3 support an additional task for those of us wanting it.

In my wisdom, I have succumbed to the delights of expensive web development tools like Altova’s XMLSpy and Adobe’s Dreamweaver. While I have found a way to get Quanta Plus to edit files on the web server directly and code hacking is my main way to improve my websites, I still will be having a bimble into Dreamweaver from time to time. I have yet to see XMLSpy’s grid view replicated in the open source world so that should remain a key tool in my arsenal. While I haven’t been looking too hard at open source XML editors recently, there remains unexplored functionality in XMLSpy that I should really explore to see if it could be harnessed.

I have included implicit references to this already but keeping Windows around also allows you to continue using familiar software. For some, this might be Microsoft Office but OpenOffice and Evolution have usurped this in my case. Photoshop Elements is a better example for me. Digitial transfers from scanners and DSLR’s will stay in the world of Linux but virtualisation allows me to process the images whatever way i want and I might just stick with the familiar for now before jumping ship to GIMP at some point in the future. With all that is written on Photoshop, having it there for learning new things seems a very sensible idea.

While open source software can conceivably address every possible, there are bound to be niches that remain outside of its reach. I use mapping software from Anquet when planning hillwalking excursions. It seems very much to be a Windows only offering and I have already downloaded a good amount of mapping so Windows has to stay if I need to use this and the routes that I have plotted out before now. Another piece of software that find its way into this bracket is my copy of SAS Learning Edition; there are times when a spot of learning at home goes a long way at work.

So, in summary, my reasons for keeping Windows around are as follows:

  • Learning new things about the thing since I am unlikely to escape its influence in the world of work
  • Using iTunes to download new music and to continue to listen to what I have already
  • Using and learning about industry standard web development tools like Dreamweaver and XMLSpy
  • Easing the transition, by continuing to use Photoshop Elements for example
  • Using niche software like Anquet mapping

I suppose that many will relate to the above but Linux still has plenty to take over some of the above. In time, DRM may disappear from the music scene and not before time; accountants and shareholders may need to learn to trust customers. NVu and Quanta Plus could yet usurp Dreamweaver and there may be an open source alternative to XMLSpy like there is for so many other areas. The Photoshop versus GIMP choice will continue to prevent itself and all that is written about the former makes it seem silly to throw it away, however good the latter is. Even with changing over Linux equivalents of applications fulfilling standard needs, it still leaves niche applications like hillwalking mapping  and that, together with the need to know what Windows might offer in the enterprise space, could be the enduring reasons for keeping it near to hand. That said, I can now go through whole days without firing a Windows VM up and that is a big change from how it was a few months ago. I suppose that it’s all too easy to stick with using one operating system at a time and that is Linux for me these days.

Choices, choices…

Choice is a very good thing but too much of it can be confusing and the world of Linux is a one very full of decisions. The first of these centres around the distro to use when taking the plunge and there can be quite a lot to it. In fact, it is a little like buying your first SLR/DSLR or your first car: you only really know what you are doing after your first one. Putting it another way, you only how to get a house built after you have done.

With that in mind, it is probably best to play a little on the fringes of the Linux world before committing yourself. It used to be that you had two main choices for your dabbling:

  • using a spare PC
  • dual booting with Windows by either partitioning a hard drive or dedicating one for your Linux needs.

In these times, innovations such as Live CD distributions and virtualisation technology keep you away from such measures. In fact, I would suggest starting with the former and progressing to the latter for more detailed perusal; it’s always easy to wipe and restore virtual machines anyway and you can evaluate several distros at the same time if you have the hard drive space. It also a great way to decide which desktop environment you like. Otherwise, terms like KDE, GNOME, XFCE, etc. might not mean much.

The mention of desktop environments brings me to software choices because they do drive what software is available to you. For instance, the Outlook lookalike that is Evolution is more likely to appear where GNOME is installed than where you have KDE. The opposite applies to the music player Amarok. Nevertheless, you do find certain stalwarts making a regular appearance; Firefox, OpenOffice and the GIMP all fall into this category.

The nice thing about Linux is that distros more often than not contain all of the software that you are likely to need. However, that doesn’t mean that its all on the disk and that you have to select what you need during the installation. There might have been a time when it might have felt like that but my recent experience has been that a minimum installation is set in place that does all of the basics and you easily can add the extras later on an as needed basis. I have also found that online updates are a strong feature too.

Picking up what you need when you need it has major advantages, the big one being that Linux grows with you. You can add items like Apache, PHP and MySQL when you know what they are and why you need them. It’s a long way from picking applications of which you know very little at installation time and with the suspicion that any future installation might land you in dependency hell while performing compilation of application source code; the temptation to install everything that you saw was a strong one. The learn before you use approach favoured by the ways that things are done nowadays is an excellent one.

Even if life is easier in the Linux camp these days, there is no harm in sketching out your software needs. Any distribution should be able to fulfill most if not all of them. As it happened, the only third party application that I have needed to install on Ubuntu without recourse to Synaptic was VMware Workstation and that procedure thankfully turned out to be pretty painless.

Accessing the host file system from a VMware virtual machine

I am very surprised at myself for not realising until recently that there is a way to make host data visible to a guest operating system installed in a VMware virtual machine other than resorting to using flash drives, CD’s, DVD’s and the like. You can copy and paste from the host into the VM but I have found that to be hit and miss at times. It was a revelation to find VMware’s Shared Folders function. I suspect that you need VMware Tools installed in the guest operating system to make it work and that may not be trivial for some Linux distributions or UNIX. I was using it with a Windows 2000 guest and a Windows XP host and it worked like a dream.

What you see below are the shared folder settings in the host’s VMware interface for that virtual machine. Just clicking on the Add… button brings up a wizard that will set up the shared folder for you; it’s all very user friendly. Look for the Edit virtual machine settings link on the VM configuration page, click that and pop over to the Options tab and this what you can get.

The end result of the above spot configuration appears in Windows Explorer like it does below. Not only are the shared folders accessible in this way but you can also map drive letters as if they were network resources, a very nice feature. It is definitely more accessible than working out Windows networking and getting things to happen that way.

PSP file gotcha

Corel Paint Shop Pro Photo XI

Having completed my evaluation of Corel’s Paint Shop Pro (a.k.a. PSP) Photo XI, I dutifully uninstalled it from my system. However, on catching up with some files that I had acquired through the application, I found that I could not open them with its forbear PSP 9. From this, I would have to conclude that Corel made a change to PSP’s native PSPIMAGE file format along the way. Having had Windows 2000 installed in a VMware virtual machine, I got back PSP XI to batch convert the files into PSD (Photoshop’s own file format) and TIFF files for the future. Carrying out the conversion was easy enough thanks to being able to select files according to their file type, something that Adobe could do with bringing into Photoshop Elements; it’s not there even in the latest version.

Hard drive partitioning

It has to be said that hard drive partitioning isn’t something that most people do very often, if at all in these days of cheap storage and system virtualisation. I must admit to having several disks in my main machine and can vouch for the virtues of virtualisation: VMware allows me to run multiple operating systems on the same machine, a very useful asset so long as enough memory is available. We can expect to hear more about virtualisation with the likes of Intel and AMD looking at hypervisor solutions for this.

Partitioning does give you what appear to be multiple drives from just the one and that is very useful when you only have a single hard drive in your PC. This was very much the case in my early computing days when catastrophic Windows 9x crashes (some self-inflicted…) often resulted in the pain of a complete re-installation of everything that had been on there. The independence offered by partitions certainly offered me peace of mind back then but 100MB Iomega Zip disks were a very useful defence in depth.

Without partitioning, my curiosity regarding the world of Linux would not have been sated though an approach involving multiple hard drives certainly came into play later on. Having been a Sun Solaris user at university, Linux certainly aroused much interest in me and I have to say that it has come a long, long way since my first ventures into its world.

While the Windows tool FDISK could partition hard drives for you, it wasn’t non-destructive: you had be prepared to restore all of your files from a backup and do a complete software re-installation following its use. It was designed for setting things up at the outset and not changing them later and that thinking seems to have pervaded the design of the Disk Management console found in XP.

For more flexible and non-destructive partitioning, Powerquest’s Partition Magic became the tool of choice, though I did have a dalliance with a package called Partition It before taking the plunge. Partition Magic is now in the Symantec stable and not a lot seems to be heard of it. Version 7, the last from Powerquest before its takeover, has been my staple but 983 errors have been thrown by the application at times and one partitioning operation went awry, forcing me to depend on my backups. Version 8 still throws 983 errors so I started to look beyond Partition Magic altogether. In my search, I happened on version 10 of Acronis Disk Director Suite. It got a strong recommendation from reviewer Davey Winder in PC Pro magazine (backup software True Image 10 from the same company also got a thumbs up from a different PC Pro reviewer) which gave some reassurance and I have to say that I agree. An operation refused by Partition Magic was completed successfully and safely so I know where my vote goes.
