Adventures & experiences in contemporary technology
This is a list that I want to build up over time and I am going to limit it to the U.K. for now. As should be apparent from any commentary that I have included, I have dealt with a few of the retailers that are listed below so I hope that it comes in useful.
My biggest purchase from this Guernsey-based lot was a Canon EOS 10D body that heralded the start of my journey into the world of digital photography at the beginning of 2005. There was a time when I was wont to buy film from them too, along with other bits and pieces but I then turned to Mailshots in Stoke-on-Trent for similar pricing and quicker delivery; it often took weeks for things to arrive from Guernsey after purchase.
Prior to my entry into the world of digital photography, this lot became a port of call for several pre-owned film cameras. A Minolta X-700 came from there in 2002 as did compatible Sigma lenses and a flash gun. During 2004, I traded in my Canon EOS 300 for an EOS 30 that they had on sale and an EOS 50E was acquired as a second body. A piece of fooling resulting from a lapse of concentration while on a visit to Harris in August has meant that the 50E has been pressed into service as my main film camera on any outings; it’s always good to have a spare and prices these days are more tempting than when I was buying second-hand equipment.
This is a name in photographic retailing that has been brought back from the dead. Before its collapse, it was the major retailer in Britain’s town centres and there was a branch in Macclesfield. However, the focus is more on online sales now with there only being a small network of city centre stores like the one on Market Street in Manchester. Having Jessops back is no bad thing and I wish them well for it was at a branch in Stockport that I bought my first-ever SLR, a Canon EOS 300, in July 2001. Purchases of Sigma lenses followed: a 70-300 mm one in Stockport and a 28-135 mm in Manchester. Admittedly, the latter of these saw more use than the former, but that always happens to me: I seem to be a one body, one lens man most of the time and it is only the prospect of a lost in quality that seems to keep me away from using super-zoom lenses.
It seems to have been Sigma lenses for my Pentax DSLR’s that I have been buying from these people. The first was an 18-125 mm offering that is the main one that I use and next came a 50-200 mm one that extends my photographic range further into the telephoto region. That I made the second purchase from them may surprise some given that there was a lengthy wait for the first one but I may have asked for a less common item and I allowed for this. The 50-200 mm lens was a far more timely arrival and there may be more purchases from them yet, subject to my actually having a need to do so.
A card reader and SD cards have been what makes up the custom that I have given this bunch. Delivery from the Isle of Man is quicker than from Jersey but you do incur additional charges even if you get that for which you are paying.
Formerly known as Warehouse Express, this operation has occasionally tempted me with promising goods at appealing prices. In the early days, a Sekonic light meter came from them but they now are a first port of call when pondering the prospect of a photographic purchase. Various cameras, lenses, filters and bags have been sourced there over the years.
UNIX (and Linux) does a wonderful trick with its file and folder shortcuts; it effectively treats them as file and folder transporters that transfer associate a file or folder that exists in one folder hierarchy with another and it is treated as if it exists in that hierarchy too. For example, the images folder under /www/htdocs/blog can have a link under /www/htdocs/ that makes it appear that its contents exist in both places without any file duplication. For instance, the pwd command cannot tell a folder from a folder shortcut. To achieve this, I use what are called symbolic links and the following command achieves the outcome in the example:
ln -s /www/htdocs/blog/images /www/htdocs/images
The first file path is the destination for the link while the second one is that for the link itself. I had a problem with Google Reader not showing up images in its feed displays so symbolic links rode to the rescue as they did for resolve a similar conundrum that I was encountering when editing posts in my hillwalking blog.
One of the nice things about the world of Linux and UNIX is the availability of multiple workspaces. In Window, you only ever get one and the likes of me can easily fill up that task bar. So the idea of parceling off different applications to different screens is useful from a housekeeping point of view so long as icons only appear in the task bar foe the open workspace; Ubuntu respects this but openSUSE doesn’t, a possible source of irritation.
However, a case can be made that UNIX/Linux needs workspaces more than Windows because of the multi-window interfaces of some of the software applications. The trouble with each of these sub-windows is that an entry appears in the task bar for each of this, creating a mess very quickly. And it can also be an issue working out which window closes the lot.
Examples of the above that come to my mind include GIMP, XSane and SAS. The Windows version of the latter’s DMS is confined to a single application window while the UNIX incarnation is composed of a window each for individual components like program editor, log, output, etc. Typing "bye" in the command line of the program editor is enough to dispatch the GUI. With GIMP, Ctrl+Q will close it down in any window apart from the "Tip of the Day" one that pops up when GIMP is first started. The same sort of behaviour also seems to dispatch XSane too.
Switching form one workspace to another is as easy as clicking the relevant icon in the task bar in all of the UNIX variants that I have used. Switching an application from one workspace to another has another common thread: finding the required entry in the application window menu.
In Ubuntu, I have seen other ways of working with workspaces. In the interface with visual effects turned off, hovering over the workspace icons in the task bar allows you to move from one to another with the wheel of your mouse. Moving an application between workspaces can be done as simply as dragging boxes from one task bar icon to another. Turning on the visual effects changes things, though. It might appear that the original functionality still works but that seems not to be the case: a matter for Canonical to resolve, perhaps?
The visual effects do provide other ways around this though. Keeping all your application windows minimised means that you can run through workspaces themselves with your wheel mouse. Moving applications between workspaces becomes as simple as grabbing the title bar and pulling the window left or right until it changes workspace. Be careful that you do the job fully though or you could have an application sitting astride two workspaces. It would appear that ideas from the sharing of a desktop across multiple monitors have percolated through to workspace behaviour.
Aside (regarding Ubuntu visual effects): I don’t know who came up with the idea of having windows wobble when they’re being moved around but it certainly is unusual, as is seeing what happens when you try prising a docked window from its mooring (particularly when you’re pulling it up from the bottom task bar). The sharper font display and bevelled screen furniture make more sense to me though; they certainly make a UI more appealing and modern.
Though my main home PC runs Linux Mint, I do like to have the facility to use Windows software from time to time and virtualisation has allowed me to continue doing that. For a good while, it was a Windows 7 guest within a VirtualBox virtual machine and, before that, one running Windows XP fulfilled the same role. However, it did feel as if things were running slower in VirtualBox than once might have been the case and I jumped ship to VMware Player. It may be proprietary and closed source but it is free of charge and has been doing what was needed. A subsequent recent upgrade of video driver on the host operating system allowed the enabling of a better graphical environment in the Windows 7 guest.
Instability
However, there were issues with stability and I lost the ability to flit from the VM window to the Linux desktop at will with the system freezing on me and needing a reboot. Working in Windows 7 using full screen mode avoided this but it did feel as I was constrained to working in a Windows machine whenever I did so. The graphics performance was imperfect too with screening refreshing being very blocky with some momentary scrambling whenever I opened the Start menu. Others would not have been as patient with that as I was though there was the matter of an expensive Photoshop licence to be guarded too.
In hindsight, a bit of pruning could have helped. An example would have been driver housekeeping in the form of removing VirtualBox Guest Additions because they could have been conflicting with their VMware counterparts. For some reason, those thoughts entered my mind and I was pondering another more expensive option instead.
Considering NAS & Windows/Linux Networking
That would have taken the form of setting aside a PC for running Windows 7 and having a NAS for sharing files between it and my Linux system. In fact, I did get to exploring what a four bay QNAP TS-412 would offer me and realised that you cannot put normal desktop hard drives into devices like that. For a while, it looked as if it would be a matter of getting drives bundled with the device or acquiring enterprise grade disks so as to main the required continuity of operation. The final edition of PC Plus highlighted another one though: the Western Digital Red range. These are part way been desktop and enterprise classifications and have been developed in association with NAS makers too.
Looking at the NAS option certainly became an education but it has exited any sort of wish list that I have. After all, there is the cost of such a setup and it’s enough to get me asking if I really need such a thing. The purchase of a Netgear FS 605 ethernet switch would have helped incorporate it but there has been no trouble sorting alternative uses for it since it bumps up the number of networked devices that I can have, never a bad capability to have. As I was to find, there was a less expensive alternative that became sufficient for my needs.
In-situ Windows 8 Upgrade
Microsoft have been making available evaluation copies of Windows 8 Enterprise that last for 90 days before expiring. One is in my hands has been running faultlessly in a VMware virtual machine for the past few weeks. That made me wonder if upgrading from Windows 7 to Windows 8 help with my main Windows VM problems. Being a curious risk-taking type I decided to answer the question for myself using the Ā£24.99 Windows Pro upgrade offer that Microsoft have been running for those not needing a disk up front; they need to pay Ā£49.99 but you can get one afterwards for an extra Ā£12.99 and Ā£3.49 postage if you wish, a slightly cheaper option. There also was a time cost in that it occupied a lot of a weekend on me but it seems to have done what was needed so it was worth the outlay.
Given the element of risk, Photoshop was deactivated to be on the safe side. That wasn’t the only pre-upgrade action that was needed because the Windows 8 Pro 32-bit upgrade needs at least 16 GB before it will proceed. Of course, there was the matter of downloading the installer from the Microsoft website too. This took care of system evaluation and paying for the software as well as the actual upgrade itself.
The installation took a few hours with virtual machine reboots along the way. Naturally, the licence key was needed too as well as the selection of a few options though there weren’t many of these. Being able to carry over settings from the pre-exisiting Windows 7 instance certainly helped with this and with making the process smoother too. No software needed reinstatement and it doesn’t feel as if the system has forgotten very much at all, a successful outcome.
Post-upgrade Actions
Just because I had a working Windows 8 instance didn’t mean that there wasn’t more to be done. In fact, it was the post-upgrade sorting that took up more time than the actual installation. For one thing, my digital mapping software wouldn’t work without .Net Framework 3.5 and turning on the operating system feature form the Control Panel fell over at the point where it was being downloaded from the Microsoft Update website. Even removing Avira Internet Security after updating it to the latest version had no effect and it was a finding during the Windows 8 system evaluation process. The solution was to mount the Windows 8 Enterprise ISO installation image that I had and issue the following command from a command prompt running with administrative privileges (it’s all one line though that’s wrapped here):
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:\sources\sxs /LimitAccess
For sake of assurance regarding compatibility, Avira has been replaced with Trend Micro Titanium Internet Security. The Avira licence won’t go to waste since I have another another home in mind for it. Removing Avira without crashing Windows 8 proved impossible though and necessitating booting Windows 8 into Safe Mode. Because of much faster startup times, that cannot be achieved with a key press at the appropriate moment because the time window is too short now. One solution is to set the Safe Boot tickbox in the Boot tab of Msconfig (or System Configuration as it otherwise calls itself) before the machine is restarted. There may be others but this was the one that I used. With Avira removed, clearing the same setting and rebooting restored normal service.
Dealing with a Dual Personality
One observer has stated that Windows 8 gives you two operating systems for the price of one: the one in the Start screen and the one on the desktop. Having got to wanting to work with one at a time, I decided to make some adjustments. Adding Classic Shell got me back a Start menu and I left out the Windows Explorer (or File Explorer as it is known in Windows 8) and Internet Explorer components. Though Classic Shell will present a desktop like what we have been getting from Windows 7 by sweeping the Start screen out of the way for you, I found that this wasn’t quick enough for my liking so I added Skip Metro Suite to do this and it seemed to do that a little faster. The tool does more than sweeping the Start screen out of the way but I have switched off these functions. Classic Shell also has been configured so the Start screen can be accessed with a press of Windows key but you can have it as you wish. It has updated too so that boot into the desktop should be faster now. As for me, I’ll leave things as they are for now. Even the possibility of using Windows’ own functionality to go directly to the traditional desktop will be left untested while things are left to settle. Tinkering can need a break.
Outcome
After all that effort, I now have a seemingly more stable Windows virtual machine running Windows 8. Flitting between it and other Linux desktop applications has not caused a system freeze so far and that was the result that I wanted. There now is no need to consider having separate Windows and Linux PC’s with a NAS for sharing files between them so that option is well off my wish-list. There are better uses for my money.
Not everyone has had my experience though because I saw a report that one user failed to update a physical machine to Windows 8 and installed Ubuntu instead; they were a Linux user anyway even if they used Fedora more than Ubuntu. It is possible to roll back from Windows 8 to the previous version of Windows because there is a windows.old directory left primarily for that purpose. However, that may not help you if you have a partially operating system that doesn’t allow you to do just that. In time, I’ll remove it using the Disk Clean-up utility by asking it to remove previous Windows installations or running File Explorer with administrator privileges. Somehow, the former approach sounds the safer.
What About Installing Afresh?
While there was a time when I went solely for upgrades when moving from one version of Windows to the next, the annoyance of the process got to me. If I had known that installing the upgrade twice onto a computer with a clean disk would suffice, it would have saved me a lot. Staring from Windows 95 (from the days when you got a full installation disk with a PC and not the rescue media that we get now) and moving through a sequence of successors not only was time consuming but it also revealed the limitations of the first in the series when it came to supporting more recent hardware. It was enough to have me buying the full retailed editions of Windows XP and Windows 7 when they were released; the latter got downloaded directly from Microsoft. These were retail versions that you could move from one computer to another but Windows 8 will not be like that. In fact, you will need to get its System Builder edition from a reseller and that can only be used on one machine. It is the merging of the former retail and OEM product offerings.
What I have been reading is that the market for full retail versions of Windows was not a big one anyway. However, it was how I used to work as you have read above and it does give you a fresh system. Most probably get Windows with a new PC and don’t go building them from scratch like I have done for more than a decade. Maybe the System Builder version would apply to me anyway and it appears to be intended for virtual machine use as well as on physical ones. More care will be needed with those licences by the looks of things and I wonder what needs not to be changed so as not to invalidate a licence. After all, making a mistake might cost between Ā£75 and Ā£120 depending on the edition.
Final Thoughts
So far Windows 8 is treating me well and I have managed to bend to my will too, always a good thing to be able to say. In time, it might be that a System Builder copy could need buying yet but I’ll leave well alone for now. Though I needed new security software, the upgrade still saved me money over a hardware solution to my home computing needs and I have a backup disk on order from Microsoft too. That I have had to spend some time settling things was a means of learning new things for me but others may not be so patient and, with Windows 7 working well enough for most, you have to ask if it’s only curious folk like me who are taking the plunge. Still, the dramatic change has re-energised the PC world in an era when smartphones and tablets have made so much of the running recently. That too is no bad thing because an unchanging technology is one that dies and there are times when big changes are needed, as much as they upset some folk. For Microsoft, this looks like one of them and it’ll be interesting to see where things go from here for PC technology.
Because my digital SLR has needed to be sent away for cleaning for a while now (in the meantime I have got good at using Photoshop Elements to clean up up pictures…), I have been on the lookout for a backup camera so that I can add photos to any trip reports on my hillwalking blog without having to wait for film to be processed. Previously, my eye was on Ricoh’s GR Digital but they have now introduced the award-winning Caplio GX100. The zoom range is a very useful 24-72 mm in 35 mm film terms and that removable electronic viewfinder looks very neat. Having a 10 megapixel sensor adds to the appeal and advanced exposure modes like manual and aperture priority. The feature list has almost ensured its ousting of the GR Digital from any wish list that I might have; the only thing outstanding is seeing how it performs in a photography magazine’s full test review. A thumbs up from there might even get me onto the acquisition trail…
In the end, I did take the plunge and acquired a Sigma 50-200 mm f4-5.6 DC OS HSM lens to fit my ever faithful Pentax K10D. After surveying a few online retailers, I plumped for Park Cameras where the total cost, including delivery, came to something to around Ā£125. This was around Ā£50 less than what others were quoting for the same lens with delivery costs yet to be added. Though the price was good at Park Cameras, I was wondering still about how they could manage to do that sort of deal when others don’t. Interestingly, it appears that the original price of the lens was around Ā£300 but that may have been at launch and prices do seem to tumble after that point in the life of many products of an electrical or electronic nature.
Unlike the last lens that I bought from them around two years ago, delivery of this item was a prompt affair with dispatch coming the day after my order and delivery on the morning after that. All in all, that’s the kind of service that I like to get. On opening the box, I was surprised to find that the lens came with a hood but without a cap. However, that was dislodged slightly from my mind when I remembered that I neglected to order a UV or skylight filter to screw into the 55 mm front of it. In the event, it was the lack of a lens cap needed sorting more than the lack of a filter. The result was that I popped in the local branch of Wildings where I found the requisite lens cap for Ā£3.99 and asked about a filter while I was at it. Much to my satisfaction, there was a UV filter that matched my needs in stock though it was that cheap at Ā£18.99 and was made by a company of which I hadn’t heard before, Massa. This was another example of good service when the shop attendant juggled two customers, a gentleman looking at buying a DSLR and myself. While I would not have wanted to disturb another sales interaction, I suppose that my wanting to complete a relatively quick purchase was what got me the attention while the other customer was left to look over a camera, something that I am sure he would have wanted to do anyway. After all, who wouldn’t?
With the extras acquired, I attached them to the front of the lens and carried out a short test (with the cap removed, of course). When it was pointed at an easy subject, the autofocus worked quickly and quietly. A misty hillside had the lens hunting so much that turning to manual focussing was needed a few times to work around something understandable. Like the 18-125 mm Sigma lens that I already had, the manual focussing ring is generously proportioned with a hyperfocal scale on it though some might think the action a little loose. In my experience though, it seems no worse than the 18-125 mm so I can live with it. Both lenses share something else in common in the form of the zoom lens having a stiffer action than the focus ring. However, the zoom lock of the 18-125 mm is replaced by an OS (Optical Stabilisation) one on the 50-200 mm and the latter has no macro facility either, another feature of the shorter lens though it remains one that I cannot ever remember using. In summary, first impressions are good but I plan to continue appraising it. Maybe an outing somewhere tomorrow might offer a good opportunity for using it a little more to get more of a feeling for its performance.
There are times when I just need to share some links outside the fleeting environment of Twitter, and this is where they might appear. The practice is very much in the spirit of the original weblog idea when it was about link sharing and not about writing down one’s thoughts as it subsequently became before sharing of photos, videos and other multimedia content became a mainstay of (legal) sharing for some people.

Archive area of old releases of Java for those who need them.
With UNIX being the basis of Linux, I have a soft spot for trying out any UNIX that can be installed on a PC. For a while, I had OpenSolaris on the go and even vaguely recall having a look at one of the BSD’s. However, any recent attempt to install one of the latter, and there are quite a few around now, got stymied by some sort of kernel panic caused by using AMD CPU’s. With the return to the Intel fold arising from the upgrade of my main home PC last year, it perhaps was time to try again.
The recent release of FreeBSD 10.0 was the cue and I downloaded a DVD image for a test installation in a VirtualBox virtual machine with 4 GB of memory and a 32 GB virtual hard drive attached (expanding storage was chosen so not all the allocated space has been taken so far). The variant of FreeBSD chosen was the 64-bit x86 one and I set to installing it in there. Though not as pretty in appearance as those in various Linux distros, the installer was not that user unfriendly to me. Mind you, I have experience of installing Arch Linux so that might have acclimatised me somewhat.
Those installation screens ask about the keyboard mapping that you want and I successfully chose one of the UK options. There was limited opportunity for adding extras though there was a short list of few from which I made some selections. User account set up also was on offer and I would have been better off knowing what groups to assign for my personal user account so as to have to avoid needing to log in as root so often following system start up later. Otherwise, all the default options were sufficient.
When the installation process was complete, it was time to boot into the new system and all that was on offer was a command line log in session. After logging in as root, it was time to press pkg into service in order to get a desktop environment in place. The first step was to install X:
pkg install xorg
Then, it was time to install a desktop environment. While using XFCE or KDE were alternatives, I chose GNOME 2 due to familiarity and more extensive instructions on the corresponding FreeBSD handbook page. Issuing the following command added GNOME and all its helper applications:
pkg install gnome2
So that GNOME starts up at the next reboot, some extra steps are needed. The first of these is to add the following line into /etc/fstab:
proc /proc procfs rw 0 0
Then, two lines were needed in /etc/rc.conf:
gdm_enable=”YES”
gnome_enable=”YES”
The first enables the GNOME display manager and the second activates other GNOME programs that are needed for a desktop session to start. With each of these in place, I got a graphical login screen at the next boot time.
With FreeDSB being a VirtualBox Guest, it was time to consult the relevant FreeBSD manual page. Here, there are sections for a number of virtual machine tools so a search was needed to find the one for VirtualBox. VirtualBox support for FreeBSD is incomplete in that there is no installation media for BSD systems though Linux and Solaris are supported along with Windows. Therefore, it is over to the FreeBSD repositories for the required software:
pkg install virtualbox-ose-additions
Aside from the virtual machine session not capturing and releasing the mouse pointer automatically, that did everything that was needed even if it was the open source edition of the drivers and their proprietary equivalents. To resolve the mouse pointer issue, I needed to temporarily disable the GNOME desktop session in /etc/rc.conf to drop down to a console only session where xorg. conf could be generated using the following commands:
Xorg -configure
cp xorg.conf.new /etc/xorg.conf
In the new xorg.conf file, the mouse section needs to be as follows:
Section “InputDevice”
IdentifierĀ “Mouse0”
DriverĀ Ā Ā Ā Ā “vboxmouse”
EndSection
If it doesn’t look like the above and it wasn’t the case for me then it needs changing. Also, any extra lines from the default set up also need removing or the mouse will not function as it should. The ALT+F1 (for accessing GNOME menus) and ALT+F2 (for running commands) keyboard shortcuts then become crucial when your mouse is not working as it should and could avert a panic too; knowing that adjusting a single configuration file will fix a problem when doing so is less accessible is not a good feeling as I discovered to my own cost. The graphics settings were fine by default but here’s what you should have in case it isn’t for you:
Section “Device”
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: “True”/”False”,
### <string>: “String”, <freq>: “<f> Hz/kHz/MHz”
### [arg]: arg optional
IdentifierĀ “Card0”
DriverĀ Ā Ā Ā Ā “vboxvideo”
VendorNameĀ “InnoTek Systemberatung GmbH”
BoardNameĀ Ā “VirtualBox Graphics Adapter”
BusIDĀ Ā Ā Ā Ā Ā “PCI:0:2:0”
EndSection
The next step is to ensure that your HAL settings are as they should. I needed to create a file in /usr/local/etc/hal/fdi/policy called 90-vboxguest.fdi that contains the following:
<?xml version=”1.0″ encoding=”utf-8″?>
<!--

With all that set, it is time to ensure that the custom user account is added to the wheel and operator groups using this command:
pw user mod [user name] -G wheel operator
Executing the above as root means that the custom account can run the su command so that logging in as root at the start of a desktop session no longer is needed. That is what being in the wheel group allows and the anyone in the operator group can shut down or restart the system. Both are facilities readily available in Linux so I fancied having them in FreeBSD too.
Being able to switch to root in a terminal session meant that I could go on to add software like Firefox, Libreoffice, GIMP, EMACS, Geany, Netbeans, Banshee and so on. There may be a line of opinion that FreeBSD is a server operating system but all of these make it more than passable for serving as a desktop one too. There may be no package management GUI as such and the ones that come with GNOME do not work either but anyone familiar with command line working will get around that.
FreeBSD may be conservative but that has its place too and being able to build up a system one item at a time teaches far more than getting everything already sorted in one hit. So far, there is enough documentation to get me going and I hope to see where else things go too. So far, the OS hasn’t been that intimidating and that’s good to see.
Under this heading, I have collected my listings of places on the web where you can purchase computing, mobile telephony and photographic equipment. As per the title, these apply to the U.K. because I have yet to import anything from beyond the shores of the island where I am writing these words. While I cannot claim to have patronised all of the emporia that are listed, the hope is that there’s enough there to enable some price checking and sourcing of goods that otherwise may not have wide availability. You never know but they even might come in useful.
As you might have guessed from the names, we are not just limiting ourselves to computers, phones and cameras but include the accessories too. In fact, since the explosion of mobile telephony and digital photography, a major crossover has development between formerly very separate business areas. The fact that many mobile phones carry the same processing power as desktop PC’s did not so many years over a decade ago rather forces the issue.
When film held sway, photography was a very analogue affair with most of the magic being made in the camera and in printing labs, including personal darkrooms. A scanner was an essential item for digitising any images. Film still lives on but the convenience of digital capture has won me over, particularly with its thrusting the processing back on my shoulders instead of paying someone else to do it. That costs time instead of money but the latter quantity is less plentiful this times. Just as my interest in desktop computing continues to persist into an age when everything is getting more and more mobile, the art of photography hasn’t been automated out of existence because it always has been the photographer that was the most important actor in the discipline.
Then, there’s the upsurge in mobile computing. While I may have been late to the game with my purchase of a BlackBerry and an Asus Eee PC in the last few months, it’s not unclear where things are going with the gadgets becoming more and more appealing. Now, it’s hard to believe that it was just under a decade ago when most mobile phones were for making and taking voice calls along with sending text messages. Yes, PDA’s were about but they didn’t seem to be as commonplace as smartphones are today. Still, it seems that mobile phone technology is going to continue evolving so it’ll be interesting to see where things go, especially with the advent of cloud computing.
With all of the changes that are in train, desktop computing is likely to continue in one form or another. We may be in the heart of a technological revolution brought on by mobile and cloud computing but there’s still something more productive about sitting at a desktop and working a machine with a mouse and keyboard. My hunch is that desktop computing is going to itself alter over the next few years with touchscreen monitors already becoming available. That development could get interesting if combined on a full specification laptop that rarely spends any time away from being plugged into a power socket.
All in all, it feels as if we are moving through a period of massive change in the world around us after a period of what felt like prolonged stability. Even in an economic downturn, it feels as if all hell has broken loose in the world of technology with old certainties being overthrown and it looks as if it is going to stay that way for a while. There may be a time of consolidation yet but the trick at the moment is control any temptations until we find any use for new shiny things that attract massive attention. Then, the listings that I have collected here might have a use.
If you ever potter over to Adobe’s online software store, a curious anomaly awaits you: electronic download editions of their software are never cheaper than the equivalent boxed versions. In fact, there are cases where the electronic version costs more than the boxed one. One would have thought that ditching the box, the disc(s) and whatever accompanies them would save Adobe money and they would pass this onto you but it does not seem to make its way into the pricing for some reason. Another thing is that selling direct should allow Adobe to undercut retailers and make more money from their software but it is the likes of Amazon that have the better prices. Whatever way you look at it, you have to admit that this pricing model doesn’t make a lot of sense.
