I know that that there better things to call a blog post than to use part of an error message that I got from Saxonica’s Saxon while I was converting XML files into PHP equivalents for the visitor information section of my main website. I use the open source Saxon-B rather than the commercial Saxon-SA and it fulfils all of my needs and version 8 and later (it has now reached 9.0.0.2) handle the XSLT 2.0 features that I need to make the transformations really clever. Also, because Saxon is available as a jar file, it is cross platform so long as you have Java on board. There are, however, some slight differences in behaviour. I now run thte thing in Linux and any Windows-style file locations are not recognised. I had the file path in a DTD declaration starting with "J:\" and that was thought to be a protocol like file, http, https, ftp and so on because of the colon. There’s no j protocol so Java gets confused and, voilà!, you get the rather obscure error that titles this post. Otherwise, the migration of the Perl script that creates XSLT files and fires off the required XML to PHP transformations was a fairly straightforward exercise once file locations and shebang line were set right.

The fancy artwork that comes with Ubuntu Studio does look appealing so I got lured into converting my vanilla Ubuntu 7.10 into something a bit more avant garde. The theme’s all very dark (you can have a peek here; file size is 1.1 MB) but it looks very smart, even if the merging of application title bar and top desktop panel due to their having the same colour and texture is a little disconcerting. My momentary lapse of discipline also got me adding a whole array of audio, graphics and movie applications that I may never use; it’s good to have them if I ever fancy a fiddle but removal is not off the agenda either. The other thing that came with the package was an alternate kernel that looks as if it might be of the real time variety, at least if the "rt" in its package name is to be believed. The main reason for mentioning that is that VMware has ceased working so I need to snag the correct kernel source code to get things going again. Let’s hope that it’s a successful venture…

Update: After a spot of poking, Synaptic offered up the required kernel header files and VMware was reinstated with only a modicum of effort. All’s well that ends well.

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.

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.

The iTunes store was a breath of fresh air following an experience of several OD2 offerings; broken downloads were a regular nuisance but that may have been down to my not having a broadband connection at the time. Its seamless mix of purchasing, downloading and playing impressed me so much that I used no other media player for my music in the days when I almost exclusively used Windows.

Now that i have jumped ship to Linux, having to fire up a Windows VM to hear my music is starting to feel a little over the top. The result is that I am keen to use DRM-free digital music when I can. Because I like to stay legal, it means that I would like to buy DRM-free files on the web. Here, iTunes leaves me down a little since most of what they offer is locked down and I have to burn a CD and extract from it to release music from its iTunes-only shackles.

So when I saw on an article on Tech.co.uk that made mention of 7Digital and that they purveyed unlocked music, my interest perked up. The file formats on offer are WMA, MP3 and AAC and there are high quality 320K variants of the latter two of these about too. Only the WMA files have any DRM associated with them. Previewing whole albums is a simple matter of clicking on a single button, a trick that iTunes would do well to learn. Payment using PayPal augments the usual credit card options and any purchases seem to be available for download more than once; pottering over to the My Locker part of your account gives you access to your purchases, another of its trump cards over iTunes. Downloading is on a file by file basis though and it is here that I notice an area usually addressed by a player like iTunes: the ability to download whole albums at once and background directory creation. Not having to have player has one advantage though: platform independence. Anyway, spot of shell scripting would resolve any file management gaps. Overall, there’s a lot to commend 7Digital and I wouldn’t be surprised if I were to return some time again. it might even usurp iTunes as my digital music store of choice…

On my blogs, I use the Bad Behaviour plugin to keep spammers at bay. It usually works very well so imagine my surprise when it started kicking me out when I tried logging into the system. I started to wonder what happened to my IP address… It now turns out that the repository being used by the plugin got moved by its author and that was the cause of my predicament (and his: he locked himself out of his own blog too!). A new version was duly released to fix the issue and all is well again. It is a tale that emphasises the important of regression testing to check that you don’t change anything that you shouldn’t.

As of the time of writing, Amazon MP3 is only available to customers in the U.S. of A so any enthusiasm for its provision of DRM-free digital music offerings has to be tempered by that limitation on its availability. Apple’s iTunes store offers some but locked down tracks are its mainstay. Amazon’s restrictions aren’t the first in the digital audio world and they are unlikely to be the last too. Pandora have done it in the world of internet radio and I seem to remember that iTunes might have done it too in their time. There may be other reasons but it might be that licensing and royalties need to be negotiated country by country, slowing the rolling out of new products across the world. The iPhone faced an equivalent situation, though that involved mobile telephony providers. Commercial considerations pervade too and I suppose that a worldwide launch of the iPhone might have been too complex a feat for Apple to manage; they probably wanted to nurture a sense of anticipation among customers in any case. It seems that things are still following the pattern that at least used to be endemic in the motion picture industry: US gets to see a film first and then everywhere else thereafter. Being able to reuse the movie film reels used in American cinemas has been the studios’ advantage from the staggered releases. Because cinema releases have been staggered, video and DVD releases were staggered too so it’s both intriguing and frustrating to see American companies using a similar launching strategy in completely different market sectors. It’s amazing how old habits die hard…

Yesterday, when taking the screen grab for my post on Quanta Plus, I did the Alt + Print Screen shuffle as usual. However, when I did so, I was greeted with a dialogue box asking me where I wanted to store the PNG file that was to be produced and what I wanted to call it. The operation was as swish as that. In Windows, the screenshot gets stuffed into the clipboard for you to extricate it with your graphics editor of choice so this was an interesting surprise. It’s the sort of thing that can make a good impression and it is striking that Linux seems to be ahead of Windows on this one. Who said Linux was less than user friendly?

On Saturday, my hillwalking and photo gallery website suffered an outage thanks to Fasthosts, the site’s hosting provider, having a security breach and deciding to change all my passwords. I won’t bore you with the details here but I had to change the password for my MySQL database from their unmemorable suggestion and hence the configuration file for the hillwalking blog. To do this, I set up Quanta Plus to edit the requisite file on the server itself. That was achieved by creating a new project, setting the protocol as FTP and completing the details in the wizard, all relatively straight forward stuff. I have a habit of doing this from Dreamweaver so it’s nice to see that an open source alternative provides the same sort of functionality.

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.

No sooner have we received Firefox 2.0.0.10 than they have already started talking about 2.0.0.11. Apparently, the latest update broke support for a tag that I have never used: canvas. This is stuff that makes you wonder about their quality control.

Because the 2.0.0.10 was a security update, Ubuntu volunteered it to me without any effort on my part. However, I am using Ubuntuzilla so I didn’t get the update coming through to my browsing world without further intervention. Launching Firefox using the gksu command allowed me to update the thing like I have been doing on Windows: Help > Check for Updates… I have got a more permanent check set up now thanks to my issuing the following command:

ubuntuzilla.py -a installupdater -p firefox
