Pondering travel device consolidation using an Apple iPad Pro 12.9"

It was a change of job in 2010 that got me interested in using devices with internet connectivity on the go. Until then, the attraction of smartphones had not been strong, but I got myself a Blackberry on a pay as you go contract, but the entry device was painfully slow, and the connectivity was 2G. It was a very sluggish start.

It was supplemented by an Asus Eee PC that I connected to the internet using broadband dongles and a Wi-Fi hub. This cumbersome arrangement did not work well on short journeys, and the variability of mobile network reception even meant that longer journeys were not all that successful either. Usage in hotels and guest houses though went better and that has meant that the miniature laptop came with me on many a journey.

In time, I moved away from broadband dongles to using smartphones as Wi-Fi hubs and that largely is how I work with laptops and tablets away from home unless there is hotel Wi-Fi available. Even trips overseas have seen me operate in much the same manner.

One feature is that we seem to carry quite a number of different gadgets with us at a time, which can cause inconvenience when going through airport security since they want to screen each device separately. When you are carrying a laptop, a tablet, a phone and a camera, it does take time to organise yourself, and you can meet impatient staff, as I found recently when returning from Oslo. Since checking in whatever you can as hold luggage helps to get around at least some of the nuisance, it also might be time for the use of better machinery to cut down on having to screen everything separately.

When you come away after an embarrassing episode, as I once did, the attractions of consolidating devices start to become plain. In fact, most probably could get with having just their phone. It is when you take activities like photography more seriously than the gadget count increases. After all, the main reason a laptop comes on trips beyond Britain and Ireland at all is to back up photos from my camera in case an SD card fails.

Parking that thought for a while, let's go back to March this year, when temptation overcame what should have been a period of personal restraint. The result was that a 32 GB 12.9" Apple iPad Pro came into my possession along with an Apple Pencil and a Logitech CREATE Backlit Keyboard Case. It should have done so, but the size of the screen did not strike me until I got it home from the Apple Store. That was one of the main attractions because maps can be shown with a greater field of view in a variety of apps, a big selling point for a hiker with a liking for maps, who wants more than what is on offer from Apple, Google or even Bing. The precision of the Pencil is another boon that makes surfing the website so much easier, and the solid connection between the case and the iPad means that keyboard usage is less fiddly than it would if it used Bluetooth. Having tried them with the BBC iPlayer app, I can confirm that the sound from the speakers is better than any other mobile device that I have used.

Already, it has come with me on trips around England and Scotland. These weekend trips saw me leave the Asus Eee PC stay at home when it normally might have come with me, and taking just a single device along with a camera or two had its uses too. While the screen is large for reading on a train, I find that it works just as well so long as you have enough space. Otherwise, combining use of a suite of apps with recourse to the web does much of the information seeking needed while on a trip away, which meant that I was not found wanting. Battery life is good too, which helps.

Those trips allowed for a little light hotel room blog post editing too and the iPad Pro did what was needed, though the ergonomics of reaching for the screen with the Pencil meant that my arm was held aloft more than was ideal. Another thing that raised questions in my mind is the appearance of word suggestions at the bottom of the screen as if this were a mobile phone, given that I wondered if these were more of a hindrance than a help given that I just fancied typing and not pointing at the screen to complete words. Though copying and pasting works too, I have found the screen-based version a little clunky. Thus, I must see if the keyboard one works just as well, though the keyboard set up is typical of a Mac and that affects word selection. You need to use the OPTION key in the keyboard shortcut that you use for this and not COMMAND or CONTROL as you might do on a PC.

Even with these eccentricities, I was left wondering if it had any utility when it came to backing up photos from digital cameras, and there is an SD card adapter that makes this possible. A failure of foresight on my part meant that the 32 GB capacity now is an obvious limitation, but I think I might have hit on a possible solution that does not need to upload to an iCloud account. It involves clearing off the photos onto a 128 GB Transcend JetDrive Go 300 so they do not clog up the iPad Pro's storage. That the device has both Lightning and USB connectivity means that you can plug it into a laptop or desktop PC afterwards too. If that were to work as I would hope, then the laptop/tablet combination that I have been using for all overseas trips could be replaced to allow a weight reduction as well as cutting the hassle at airport security.

Trips to Ireland still may see my sticking with a tried and tested combination though because I often have needed to do some printing while over there. While I have been able to print a test document from an iPad Mini on my home network-connected printer, not every model supports this and that for NFC or Air Print is not universal either. If this were not an obstacle, apps like Pages, Numbers and Keynote could have their uses for business-related work and there are web-based offerings from Google, Microsoft and others too.

In conclusion, I have found that my iPad Pro does so much of what I need on a trip away that retiring the laptop/tablet combination for most of these is not as outrageous as it once would have seemed. In some ways, iOS has a way to go yet, before it could take over from macOS, yet it remains in development so it will be interesting to see what happens next. All the while, hybrid devices running Windows 10 are becoming more pervasive, so that might provide Apple with the encouragement that it needs.

Piggybacking an Android Wi-Fi device off your Windows PC's internet connection

One of the disadvantages of my Google/Asus Nexus 7 is that it needs a Wi-Fi connection to use. Most of the time, this is not a problem since I also have a Huawei mobile Wi-Fi hub from T-Mobile and this seems to work just about anywhere in the U.K. Away from the U.K. though, it won't work because roaming is not switched on for it and that may be no bad thing with the fees that could introduce. While my HTC Desire S could deputise, I need to watch costs with that too.

There's also the factor of download caps, and those apply both to the Huawei and to the HTC. Recently, I added Anquet's Outdoor Map Navigator (OMN) to my Nexus 7 through the Google Play Store for a fee of £7 and that allows access to any walking maps that I have bought from Anquet. However, those are large downloads, so the caps start to come into play. Frugality would help, but I began to look at other possibilities that make use of a laptop's Wi-Fi functionality.

Looking on the web, I found two options for this that work on Windows 7 (8 should be OK too): Connectify Hotspot and Virtual Router Manager. The first of these is commercial software, yet there is a Lite edition for those wanting to try it out; that it is not a time limited demo is not something that I can confirm though that did not seem to be the case since it looked as if only features were missing from it that you'd get if you paid for the Pro variant. The second option is an open source one that is free of charge apart from an invitation to donate to the project.

Though online tutorials show the usage of either of these to be straightforward, my experiences were not all that positive at the outset. In fact, there was something that I needed to do, which is how this post has come to exist at all. That happened even after the restart that Connectify Hotspot needed as part of its installation; it runs as a system service, which is why the restart was needed. In fact, it was Virtual Router Manager that told me what the issue was, and it needed no reboot. Neither did it cause network disconnection of a laptop like the Connectify offering did on me and that was the cause of its ejection from that system; limitations in favour of its paid addition aside, it may have the snazzier interface, but I'll take effective simplicity any day.

Using Virtual Router Manager turns out to be simple enough. It needs a network name (also known as an SSID), a password to restrict who accesses the network and the internet connection to be shared. In my case, the was Local Area Connection on the dropdown list. With all the required information entered, I was ready to start the router using the Start Network Router button. The text on this button changes to Stop Network Router when the hub is operational, or at least it should have done for me on the first time that I ran it. What I got instead was the following message:

The group or resource is not in the correct state to perform the requested operation.

While the above may not say all that much, it becomes more than ample information if you enter it into the likes of Google. Behind the scenes, Virtual Router Manager uses native Windows functionality to create a Wi-Fi hub from a PC, and it appears to be the Microsoft Virtual Wi-Fi Miniport Adapter from what I have seen. When I tried setting up an ad hoc Wi-Fi network from a laptop to the Nexus 7 using Windows' own network set up capability via its Control Panel, it didn't do what I needed, so there might be something that third party software can do. So, the interesting thing about the solution to my Virtual Router Manager problem was that it needed me to delve into the innards of Windows a little.

Firstly, there's running Command Prompt (All Programs > Accessories) from the Start Menu with Administrator privileges. It helps here if the account with which you log into Windows is in the Administrator group, since all you have to do then is right-click on the Start Menu entry and choose Run as administrator entry in the pop-up context menu. With a command line window now open, you then need to issue the following command:

netsh wlan set hostednetwork mode=allow ssid=[network name] key=[password] keyUsage=persistent

When that had done its thing, Virtual Router Manager worked without a hitch though it did turn itself after a while and that may be no bad thing from the security standpoint. On the Android side, it was a matter of going in Settings > Wi-Fi and choosing the new network that was created on the laptop. This sort of thing may apply to other types of tablet (Dare I mention iPads?) so you could connect anything to the hub without needing to do any more on the Windows side.

For those wanting to know what's going on behind the scenes on Windows, there's a useful tutorial on Instructables that shows what third party software is saving you from having to do. Even if I never go down the more DIY route, I probably have saved myself having to buy a mobile Wi-Fi hub for any trips to Éire. For now, the Irish 3G dongle that I already have should be enough.

A little more freedom

A few weeks ago, I decided to address the fact that my Toshiba laptop have next to useless battery life. The arrival of an issue of PC Pro that included a review of lower cost laptops was another spur for looking on the web to see what was in stock at nearby chain stores. In the end, I plumped for an HP Pavilion dm4 from a branch of Argos. In fact, they seem to have a wider range of laptops than PC World!

The Pavilion dm4 seems to come in two editions and I opted for the heavier of these, though it still is lighter than my Toshiba Equium as I found on a recent trip away from home. Its battery life is a revelation for someone who never has got anything better than three hours from a netbook. Having more than five hours certainly makes it suitable for those longer train journeys away from home, and I have seen remaining battery life being quoted as exceeding seven hours from time to time, though I wouldn't depend on that.

Of course, having longer battery life would be pointless if the machine didn't do what else was asked of it. It comes with the 64-bit of Windows 7 and this taught me that this edition of the operating system also runs 32-bit software, a reassuring discovering. There's a trial version of Office 2010 on there too and, having a licence key for the Home and Student edition, I fully activated it. Otherwise, I added a few extras to make myself at home, such as Dropbox and VirtuaWin (for virtual desktops as I would in Linux). While I was playing with the idea of adding Ubuntu using Wubi, I am not planning to set up dual booting of Windows and Linux like I have on the Toshiba. Little developments like this can wait.

Regarding the hardware, the CPU is an Intel Core i3 affair and there's 4 MB of memory on board. The 14" screen makes for a more compact machine without making it too diminutive. The keyboard is of the scrabble-key variety and works well too, as does the trackpad. There's a fingerprint scanner for logging in and out without using a password, but I haven't got to check how this works so far. It all zips along without any delays, and that's all that anyone can ask of a computer.

There is one eccentricity in my eyes though: it appears that the functions need to be used in combination with the Fn key for them to work like they would on a desktop machine. That makes functions like changing the brightness of the screen, adjusting the sound of the speakers and turning the Wi-Fi on and off more accessible. My Asus Eee PC netbook and the Toshiba Equium both have things the other way around, so I found this set of affairs unusual, but it's just a point to remember rather than being a nuisance.

Though HP may have had its wobbles regarding its future in the PC making business, the Pavilion feels well put together and very solidly built. The premium paid over the others on my shortlist seems to have been worth it. If HP does go down the premium laptop route as has been reported recently, this is the kind of quality that they would need to deliver to just higher prices. Saying that, is this the time to do such a thing with other devices challenging the PC's place in consumer computing? It would be a shame to lose the likes of the Pavilion dm4 from the market to an act of folly.

Battery life

In recent times, I have lugged my Toshiba Equium with me while working away from home; I needed a full screen laptop of my own for attending to various things after work hours, so it needs to come with me. It's not the most portable of things with its weight and the lack of battery life. Now that I think of it, I reckon that it's more of a desktop PC replacement machine than a mobile workhorse. After all, it only lasts an hour on its own battery away from a power socket. Virgin Trains' tightness with such things on their Pendolino trains is another matter...

Unless my BlackBerry is discounted, battery life seems to be something with which I haven't had much luck because my Asus Eee PC isn't too brilliant either. Without decent power management, two hours of battery life appears to be as good as I get from it. However, three to four hours become possible with better power management software on board. That makes the netbook even more usable, though there are others out there offering longer battery life. Still, I am not tempted by these because the gadget works well enough for me that I don't need to wonder about how money I am spending on building a mobile computing collection.

While I am not keen on spending too much cash or having a collection of computers, the battery life situation with my Toshiba more than gives me pause for thought. The figures quoted for MacBooks had me looking at them, even if they aren't at all cheap. Curiosity about the world of the Mac may make them attractive to me, only for the prices to forestall that, and the concept was left on the shelf.

Recently, PC Pro ran a remarkably well-timed review of laptops offering long battery life (in issue 205). The minimum lifetime in this collection was over five hours, so the list of reviewed devices is an interesting one for me. In fact, it even may become a shortlist should I decide to spend money on buying a more portable laptop than the Toshiba that I already have. The seventeen-hour battery life for a Sony VAIO SB series sounds intriguing, even if you need to buy an accessory to gain this. That it does over seven hours without the extra battery slice makes it more than attractive anyway. The review was food for thought and should come in handy if I decide that money needs spending.

Extending ASUS Eee PC Battery Life Without Changing From Ubuntu 11.04

While it might just be my experience of the things, I do tend to take claims about laptop or netbook battery life with a pinch of salt. After all, I have a Toshiba laptop that only lasts an hour or two away from the mains and that runs Windows 7. For a long time, my ASUS Eee PC netbook looked like that too, only for a spot of investigation to reveal that there was something that I could do to extend the length of time before the battery ran out of charge. For now, the solution would seem to be installing eee-control and here's what I needed to do that for Ubuntu 11.04, which has gained a reputation for being a bit of a power hog on netbooks if various tests are to be believed.

Because eee-control is not in the standard Ubuntu repositories, you need to add an extra one for install in the usual way. To make this happen, launch Synaptic and find the entry named Repositories on the Settings menu and click on it. If there's no sign of it, then Software Sources (this was missing on my ASUS) needs to be installed using the following command:

sudo apt-get install software-properties-gtk

Once Software Sources opens up after you enter your password, go to the Other Software tab. The next step is to click on the Add button and enter the following into the APT Line box before clicking on the Add Source button:

ppa:eee-control/eee-control

With that done, all that's needed is to issue the following command before rebooting the machine on completion of the installation:

sudo apt-get install eee-control

When you are logged back in to get your desktop, you'll notice a new icon on your desktop with the Eee logo, and clicking on this reveals a menu with a number of useful options. Among these is the ability to turn off a number of devices such as the camera, Wi-Fi or card reader. After that, there's the entry named Preferences in the Advanced submenu for turning on such things as setting performance to Powersave for battery-powered operation or smart fan control. The notifications issued to you can be controlled too, as can be a number of customisable keyboard shortcuts useful for quickly starting a few applications.

So far, I have seen a largely untended machine last around four hours, and that's around double what I have been getting until now. Of course, what really is needed is a test with constant use to see how it gets on. Even if I see lifetimes of around 3 hours, this still will be an improvement. Nevertheless, being of a sceptical nature, I will not scotch the idea of getting a spare battery just yet.

Manually adding an entry for Windows 7 to an Ubuntu GRUB2 menu

A recent endeavour of mine has been to set up a dual-booting arrangement on my Toshiba Equium laptop, with Ubuntu 10.10 and Windows 7 side by side on there. However, unlike the same attempt with my Asus Eee PC where Windows XP coexists with Ubuntu, there was no menu entry on the GRUB (I understand that Ubuntu has had version 2 of this since 9.04 though the internal version is of the form 1.9x; you can issue grub-install -v at the command line to find out what version you have on your system) menu afterwards. Thankfully, I eventually figured out how to do this and the process is shared here in a more coherent order than the one in which I discovered all the steps.

The first step is to edit /etc/grub.d/40_custom (using sudo) and add the following lines to the bottom of the file:

menuentry 'Windows 7' {
set root='(hd0,msdos2)'
chainloader +1
}

Since the location of the Windows installation can differ widely, I need to explain the "set root" line because (hd0,msdos2) refers to /dev/sda2 on my machine. More generally, hd0 (or /dev/sda elsewhere) refers to the first hard disk installed in any PC, with hd1 (or /dev/sdb elsewhere) being the second and so on. While I was expecting to see entries like (hd0,6) in /boot/grub/grub.cfg, what I saw were ones like (hd0,msdos6) instead with the number in the text after the comma being the partition identifier; 1 is the first (sda1), 2 (sda2) is the second and so on. The next line (staring with chainloader) tells GRUB to load the first sector of the Windows drive so that it can boot. After all that decoding, my final remark on what's above is a simple one: the text "Windows 7" is what will appear in the GRUB menu, so you can change this as you see fit.

After saving 40_custom, the next step is to issue the following command to update grub.cfg:

sudo update-grub2

Once that has done its business, then you can look into /boot/grub/grub.cfg to check that the text added into 40_custom has found its way in there. That is important because this is the file read by GRUB2 when it builds the menu that appears at start-up time. A system reboot will prove conclusively that the new entry has been added successfully. Then, there's the matter of selectively to see if Windows loads properly like it did for me, once I chose the correct disk partition for the menu entry, that is!

Why go elsewhere when you can get it at Argos?

It is perhaps a sign of the technological times in which we live that even mainstream stores like Argos stock computing equipment these days. For instance, last weekend, I bought a Seagate Expansion 2 GB external hard drive in there for backing up my digital photo collection and never got to a local independent computer shop like I had planned to do. Maybe, it was the convenience and lack of fuss with a catalogue shop that swung it for me. In this case, the largest size at the other place was 1 GB according to its website anyway.

Other items bought from the pervasive chain have included a BlackBerry, a Vodafone mobile broadband dongle and an Asus Eee PC. All have done what I have asked of them and without any trouble, yet it does make me wonder about the threat to the specialist PC stores from their more mainstream competitors, and it isn't just Argos either. Tesco also tempts folk into their stores with technological goods, so I must own up to having a cheap DVD player from there.

In former times, I might have been lured into purchasing at online stores until the reality of dealing with inflexible delivery services took away the shine after a few years. After all, I'd prefer not to burden neighbours with taking delivery of any purchases. My current job offers the possibility of some home working so that might be an option for those things that do need delivering, but there remains a certain immediacy to going into a real shop for what you need and then to take it away on the day (having paid for it, of course) that is difficult to beat.

While I tend to decide what to get using my mind after doing some research, others may prefer the idea of getting some advice in a shop, which is where the specialists score. In fact, it may be the only way that they are going to cope with the onslaught from megastores like Argos and Tesco. All this reminds me that going to a local independent shop next time is in order because they cannot be doing brilliantly in these cash-straightened times.

An Eee PC

Having had an Asus Eee PC 1001 HA for a few weeks now, I thought that it might be opportune to share a few words about the thing on here. The first thing that struck me when I got it was the size of the box in which it came. Being accustomed to things coming in large boxes meant the relatively diminutive size of the package was hard not to notice. Within that small box was the netbook itself, along with the requisite power cable and not much else apart from warranty and quick-start guides; so that's how they kept things small.

Though I was well aware of the size of a netbook from previous bouts of window shopping, the small size of something with a 10" screen hadn't embedded itself into my consciousness. Despite that, it came with more items that reflect desktop computing than might be expected. First, there's a 160 GB hard disk and 1 GB of memory, neither of which is disgraceful and the memory module sits behind a panel opened by loosening a screw, which leaves me wondering about adding more. Sockets for network and VGA cables are included, along with three USB ports and sockets for a set of headphones and for a microphone. Portability starts to come to the fore with the inclusion of an Intel Atom CPU and a socket for an SD card. Unusual inclusions come in the form of an onboard webcam and microphone, both of which I intend to leave in the off position for the sake of privacy. Wi-Fi is another networking option, so you're not short of features. The keyboard is not too compromised either, and the mouse trackpad is the sort of thing that you'd find on full size laptops. With the latter, you can use gestures too, so I need to learn what ones are available.

The operating system that comes with the machine is Windows XP, and there are some extras bundled with it. These include a trial of Trend Micro as an initial security software option, as well as Microsoft Works and a trial of Microsoft Office 2007. Then, there are some Asus utilities too, though they are not so useful to me. All in all, none of these burden the processing power too much and IE8 comes installed too. Being a tinkerer, I have put some of the sorts of things that I'd have on a full size PC on there. Examples include Mozilla Firefox, Google Chrome, Adobe Reader and Adobe Digital Editions. Pushing the boat out further, I used Wubi to get Ubuntu 10.04 on there in the same way as I have done with my 15" Toshiba laptop. So far, nothing seems to overwhelm the available processing power, though I am left wondering about battery life.

The mention of battery life brings me to mulling over how well the machine operates. So far, I am finding that the battery lasts around three hours, much longer than on my Toshiba but nothing startling either. Nevertheless, it does preserve things by going into sleep mode when you leave it unattended for long enough. Still, I'd be inclined to find a socket if I was undertaking a long train journey.

According to the specifications, it is supposed to weigh around 1.4 kg and that seems not to be a weight that has been a burden to carry so far and the smaller size makes it easy to pop into any bag. It also seems sufficiently robust to allow its carrying by bicycle, though I wouldn't be inclined to carry it over too many rough roads. In fact, the manufacturer advises against carrying it anywhere (by bike or otherwise) without switching it off first, but that's a common sense precaution.

Start-up times are respectable, though you feel the time going by when you're on a bus for a forty-minute journey, and shutdown needs some time set aside near the end. The screen resolution can be increased to 1024x600 and the shallowness can be noticed, reminding you that you are using a portable machine. For that reason, there have been times when I hit the F11 key to get a full screen web browser session. Coupled with the Vodafone mobile broadband dongle that I have, it has done some useful things for me while on the move so long as there is sufficient signal strength (seeing the type of connection change between 3G, EDGE and GPRS is instructive). All in all, it's not a chore to use, as long as Internet connections aren't temperamental.

An avalanche of innovation?

It seems that, almost despite the uncertain times or maybe because of them, it feels like an era of change on the technology front. Computing is the domain of many of the postings on this website, and a hell of a lot seems to be going mobile at the moment. For a good while, I managed to stay clear of the attractions of smartphones until a change of job convinced me that having a BlackBerry was a good idea. Though the small size of the thing really places limitations on the sort of web surfing experience that you can have with it, you can keep an eye on the weather, news, traffic, bus and train times so long as the website in question is built for mobile browsing. Otherwise, it's more of a nuisance than a patchy phone network (in the U.K., T-Mobile could do better on this score, as I have discovered for myself; thankfully, a merger with the Orange network is coming next month).

Speaking of mobile websites, it almost feels as if a free for all has recurred for web designers. Just when the desktop or laptop computing situation had more or less stabilised, along came a whole pile of mobile phone platforms to make things interesting again. Familiar names like Opera, Safari, Firefox and even Internet Explorer are to be found popping up on handheld devices these days along with less familiar ones like Web 'n' Walk or BOLT. The operating system choices vary too, with iOS, Android, Symbian, Windows and others all competing for attention. It is the sort of flowering of innovation that makes one wonder if a time will come when things begin to consolidate, but it doesn't look like that at the moment.

The transformation of mobile phones into handheld computers isn't the only big change in computing, with the traditional formats of desktop and laptop PC's being flexed in all sorts of ways. First, there's the appearance of netbooks, and I have succumbed to the idea of owning an Asus Eee. Though you realise that these are not full size laptops, it still didn't hit me how small these were until I owned one.  They are undeniably portable, while tablets look even more interesting in the aftermath of Apple's iPad. Though you may call them over-sized mobile photo frames, the idea of making a touchscreen do the work for you has made the concept fly for many. Even so, I cannot say that I'm overly tempted, though I have said that before about other things.

Another area of interest for me is photography, and it is around this time of year that all sorts of innovations are revealed to the public. It's a long way from what, we thought, was the digital photography revolution when digital imaging sensors started to take the place of camera film in otherwise conventional compact and SLR cameras, making the former far more versatile than they used to be. Now, we have SLD cameras from Olympus, Panasonic, Samsung and Sony that eschew the reflex mirror and prism arrangement of an SLR using digital sensor and electronic viewfinders while offering the possibility of lens interchangeability and better quality than might be expected from such small cameras. Lately, Sony has offered SLR-style cameras with translucent mirror technology instead of the conventional mirror that is flipped out of the way when a photographic image is captured.  Change doesn't end there, with movie making capabilities being part of the tool set of many a newly launched compact, SLD and SLR camera. The pixel race also seems to have ended though increases still happen as with the Pentax K-5 and Canon EOS 60D (both otherwise conventional offerings that have caught my eye, though so much comes on the market at this time of year that waiting is better for the bank balance).

The mention of digital photography brings to mind the subject of digital image processing and Adobe Photoshop Elements 9 is just announced after Photoshop CS5 appeared earlier this year. It almost feels as if a new version of Photoshop or its consumer cousin is released every year, causing me to skip releases when I don't see the point. Elements 6 and 8 were such versions for me, so I'll be in no hurry to upgrade to 9 yet either, even if the prospect of using content aware filling to eradicate unwanted objects from images is tempting. Nevertheless, that shouldn't stop anyone trying to exclude them in the first place. In fact, I may need to reduce the overall number of images that I collect in favour of coming away with only the better ones. The outstanding question on this is: can I slow down and calm my eagerness to bring at least one good image away from an outing by capturing anything that seems promising at the time? Some experimentation but being a little more choosy can save work later on.

While back on the subject of software, I'll voyage in to the world of the web before bringing these meanderings to a close. It almost feels as if there are web-based applications following web-based applications these days, when Twitter and Facebook nearly have become household names and cloud computing is a phrase that turns up all over the place.  In fact, the former seems to have encouraged a whole swathe of applications all of itself. Applications written using technologies well-used on the web must stuff many a mobile phone app store too and that brings me full circle for it is these that put so much functionality on our handsets with Java seemingly powering those I use on my BlackBerry. Then there's the spat between Apple and Adobe regarding the former's support for Flash.

To close this mental amble, there may be technologies that didn't come to mind while I was pondering this piece, but they doubtless enliven the technological landscape too. However, what I have described is enough to take me back more than ten years ago, when desktop computing and the world of the web were a lot more nascent than is the case today. Then, the changes that were ongoing felt a little exciting now that I look back on them, and it does feel as if the same sort of thing is recurring though with things like phones creating the interest in place of new developments in desktop computing such as a new version of Window (though 7 was anticipated after Vista). Web designers may complain about a lack of standardisation, and they're not wrong, yet this may be an era of technological change that in time may be remembered with its own fondness too.

Best left until later in the year?

In the middle of last year, my home computing experience was one of feeling displaced. A combination of a stupid accident and a power outage had rendered my main PC unusable. What followed was an enforced upgrade that used a combination that was familiar to me: Gigabyte motherboard, AMD CPU and Crucial memory. However, assembling that lot and attaching components from the old system from the old system resulted in the sound of whirring fans but nothing appearing on-screen. Not having useful beeps to guide me meant that it was a case of undertaking educated guesswork until the motherboard was found to be at fault.

In a situation like this, a better developed knowledge of electronics would have been handy and might have saved me money too. As for the motherboard, it is hard to say whether it was a faulty set from the outset or whether there was a mishap along the way, either due to ineptitude with static or incompatibility with a power supply. What really tells the tale on the mainboard was the fact that all the other components are working well in other circumstances, even that old power supply.

A few years back, I had another experience with a problematic motherboard, an Asus this time, that ate CPU's and damaged a hard drive before I stabilised things. That was another upgrade attempted in the first half of the year. My first round of PC building was in the third quarter of 1998 and that went smoothly once I realised that a new case was needed. Similarly, another PC rebuild around the same time of year in 2005 was equally painless. Based on these experiences, I should not be blamed for waiting until later in the year before doing another rebuild, preferably a planned one rather than an emergency.

Of course, there may be another factor involved too. The hint was a non-working Sony DVD writer that was acquired early last year when it really was obvious that we were in the middle of a downturn. Could older unsold inventory be a contributor? Well, it fits in with seeing poor results twice, In addition, it would certainly tally with a problematical PC rebuild in 2002 following the end of the Dot-com bubble and after the deadly Al-Qaeda attack on New York's World Trade Centre. An IBM hard drive that was acquired may not have been the best example of the bunch, and the same comment could apply to the Asus motherboard. Though the resulting construction may have been limping, it was working tolerably.

In contrast, last year's episode had me launched into using a Toshiba laptop and a spare older PC for my needs, with an external hard drive enclosure used to extract my data onto other external hard drives to keep me going. While it felt like a precarious arrangement, it was a useful experience in ways too.

There was cause for making acquaintance with nearby PC component stores that I hadn't visited before, and I got to learn about things that otherwise wouldn't have come my way. Using an external hard drive enclosure for accessing data on hard drives from a non-functioning PC is one of these. Discovering that it is possible to boot from external optical and hard disk drives came as a surprise too and will work so long as there is motherboard support for it.

Another experience came from a crisis of confidence that had me acquiring a bare-bones system from Novatech and populating it with optical and hard disk drives. Then, I discovered that I have no need for power supplies rated more than 300 watts (around 200 W suffices). Turning my PC off more often became a habit, friendly both to the planet and to household running costs too.

Then, there's the beneficial practice of shopping locally, which can suffice. You may not get what PC magazines stick on their hot lists, but shopping online for those pieces doesn't guarantee success either. All of these were useful lessons and, while I'd rather not throw away good money after bad, it goes to show that even unsuccessful acquisitions had something to offer in the form of learning opportunities. Whether you consider that is worthwhile is up to you.
