A little more freedom

December 10, 2011 2 comments

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 and I ended up looking on the web to see what was in stock at nearby chain stores. In the end, I plumped for an HP Pavilion dm4 and it was Argos that supplied yet another piece of computing kit to me. In fact, they seem to have a wider range of laptops than PC World!

The Pavillion 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 thought 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 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 screen is a 14″ one and that 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 checking 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 and it seems that the functions need to be used in combination with Fn 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 WiFi 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.

HP may have had its wobbles regarding its future in the PC making business but the Pavilion feels well put together and very solidly built. It commanded a little premium over the others on my shortlist but it 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 would 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.

Pondering storage options

June 1, 2011 One comment

The combination of curiosity and a little spare time had me browsing online computing technology stores recently. A spot of CD and DVD burning brought on by a flurry of Linux distribution testing reminded me of the possibility. Because I have built up a sizeable library of digital photos, ensuring that I have backups of them is something that needs doing. A 2 GB Samsung external hard drive is brought to life every now and again for that purpose but the prospect of using Blu-Ray discs has appealed to me. After all capacities of 25 GB for single layer discs and 50 GB for dual layer ones sound not inappropriate for my purposes. However, they aren’t a cheap option at the time of writing with each disc costing in the region of £3-4 at one place where I was looking. The cost of BD writers themselves seems not to be so bad though with a few in the £60-100 bracket; any lower than this and you could end up with a combo drive that reads Blu-Ray discs and writes to DVD’s and CD’s so a modicum of concentration is needed. As attractive as the idea might be, the cost of BD media means that I’ll wait a little while before deciding to take the plunge. The price premium at the moment is a reminder of the way that things used to be when CD and DVD writers first came on the market. It is very telling when discs come packaged in jewel cases, something that you won’t see too often with CD’s or DVD’s.

Another piece of storage excitement that hasn’t escaped me is the advent of SSD hard drives. With no moving parts like in conventional hard drives, they bring a speed boost. Concerns about their lifetimes and the numbers of read/write events per drive would stall me when it comes to storing personal data on them but using them for the likes of operating system files sounds attractive, especially with my partiality to Linux perhaps not hammering drives so much. As with any new technology, there is a price premium though a drive big enough for hosting an operating system can be acquired for less than £100. As with many of my hardware purchase brainwaves, there’s no rush but this is an option that I’ll keep at the back of my mind.

Another appealing notion is the idea of getting a NAS so that files can be shared between a few computers. While I have seen prices starting at just above £70 for single disk enclosures, these generally are a more expensive option than external drives and that’s before you consider the cost of any hard drives. Nevertheless, the advantages of a unit containing more than a single hard drive while operating as a print server for any compatible printer too. When you get to 4 or 5 hard drive trays, then the cost has mounted but that could be when they pay their way too. What reminded me of these was a bookazine on home networking that I recently found at a branch of WHSmith’s and their attractions are subject to the networking side of things being made to work without a drama. Once that’s out of the way, then their usefulness really does appeal.

Mulling over all these brainwaves is one thing but it doesn’t mean that the purse strings will become too loose in this age of economic constraint. In fact, pondering them may serve to staunch any impulse purchases. Sometimes, a spot of virtual shopping serves to control things rather than losing the run of oneself.

A bigger screen?

February 23, 2010 No comments

A recent bit of thinking has caused me to cast my mind back over all the screens that have sat in front of me while working with computers over the years. Well, things have come a long way from the spare television that I used with a Commodore 64 that I occasionally got to exploring the thing. Needless to say, a variety of dedicated CRT screens ensued as I started to make use of Apple and IBM compatible PC’s provided in computing labs and other such places before I bought an example of the latter as my first ever PC of my own. That sported a 15″ display that stood out a little in times when 14″ ones were mainstream but a 17″ Iiyama followed it when its operational quality deteriorated. That Iiyama came south with me from Edinburgh as I moved to where the work was and offered sterling service before it too started to succumb to aging.

During the time that the Iiyama CRT screen was my mainstay at home, there were changes afoot in the world of computer displays. A weighty 21″ Philips screen was what greeted me on a first day at work but 21″ Eizo LCD displays were set to replace those behemoths and remain in use as if to prove the longevity of LCD panels and the validity of using what had been sufficient for laptops for a decade or so. In fact, the same comment regarding reliability applies to the screen that now is what I use at home, a 17″ Iiyama LCD panel (yes, I stuck with the same brand when I changed technologies longer ago than I like to remember).

However, that hasn’t stopped me wondering about my display needs and it’s screen size that is making me think rather than the reliability of the current panel. That is a reflection on how my home computing needs have changed over time and they show how my non-computing interests have evolved too. Photography is but one of these and the move the digital capture has brought with a greater deal of image processing, so much that I wonder if I need to make less photos rather than bringing home so many that it can be hard to pick out the ones that are deserving of a wider viewing. That is but one area where a bigger screen would help but there is another and it arises from my interest in exploring countryside on foot or on my bike: digital mapping. When planning outings, it would be nice to have a wider field of view to be able to see more at a larger scale.

None of the above is a showstopper that would be the case if the screen itself was unreliable so I am going to take my time on this one. The prospect of sharing desktops across two screens is another idea but that needs some thought about where it all would fit; the room that I have set aside for working at my computer isn’t the largest but it’ll need to do. After the space side of things, then there’s the matter of setting up the hardware. Quite how a dual display is going to work with a KVM setup is something to explore as is the adding of extra video cards to existing machines. After the hardware fiddling, the software side of things is not a concern that I have because of when I used laptop as my main machine for a while last year. That confirmed that Windows (Vista but it has been possible since 2000 anyway…) and Ubuntu (other modern Linux distributions should work too…) can cope with desktop sharing out of the box.

Apart from the nice thoughts of having more desktop space, the other tempting side to all of this is what you can get for not much outlay. It isn’t impossible to get a 22″ display for less than £200 and the prices for 24″ ones are tempting too. That’s a far cry from paying next to £300 (if my memory serves me correctly) for that 17″ Iiyama and I’d hope that the quality is as good as ever.

It’s all very well talking about pricing but you need to sit down and choose a make and model when you get to deciding on a purchase. There is plenty of choice so that would take a while but magazine reviews will come in handy here. Saying that, last year’s computing misadventures have me questioning the sense of going for what a magazine places on its A-list. They also have me minded to go to a nearby computer shop to make a purchase rather than choosing a supplier on the web; it is easier to take back a faulty unit if you don’t have far to go. Speaking of faulty units, last year has left me contemplating waiting until the year is older before making any acquisitions of computer kit. All of that has put the idea of buying a new screen on the low priority list, nice to have but not essential. For now, that is where it stays but you never know what the attractions of a shiny new thing can do…

Consolidation

November 19, 2009 No comments

For a while, the Windows computing side of my life has been spread across far too many versions of the pervasive operating systems with the list including 2000 (desktop and server), XP, 2003 Server, Vista and 7; 9x hasn’t been part of my life for what feels like an age. At home, XP has been the mainstay for my Windows computing needs with Vista Home Premium loaded on my Toshiba laptop. The latter variant came in for more use during that period of home computing “homelessness” and, despite a cacophony of complaints from some, it seemed to work well enough. Since the start of the year, 7 has also been in my sights with beta and release candidate instances in virtual machines leaving me impressed enough to go popping the final version onto both the laptop and in a VM on my main PC. Microsoft finally have got around to checking product keys over the net so that meant a licence purchase for each installation using the same downloaded 32-bit ISO image. 7 still is doing well by me so I am beginning to wonder whether having an XP VM is becoming pointless. The reason for that train of thought is that 7 is becoming the only version that I really need for anything that takes me into the world of Windows.

Work is a different matter with a recent move away from Windows 2000 to Vista heavily reducing my exposure to the venerable old stager (businesses usually take longer to migrate and any good IT manager usually delays any migration by a year anyway). 2000 is sufficiently outmoded by now that even my brother was considering a move to 7 for his work because of al the Office 2007 files that have been coming his way. He may be no technical user but the bad press gained by Vista hasn’t passed him by so a certain wariness is understandable. Saying that, my experiences with Vista haven’t been unpleasant and it always worked well on the laptop and the same also can be said for its corporate desktop counterpart. Much of the noise centered around issues of hardware and software compatibility and that certainly is apparent at work with my having some creases left to straighten.

With all of this general forward heaving, you might think that IE6 would be shuffling its mortal coil by now but a recent check on visitor statistics for this website places it at about 13% share, tantalisingly close to oblivion but still too large to ignore it completely. All in all, it is lingering like that earlier blight of web design, Netscape 4.x. If I was planning a big change to the site design, setting up a Win2K VM would be in order not to completely put off those labouring with the old curmudgeon. For smaller changes, the temptation is not to bother checking but that is questionable when XP is set to live on for a while yet. That came with IE6 and there must be users labouring with the old curmudgeon and that’s ironic with IE8 being available for SP2 since its original launch a while back. Where all this is leading me is towards the idea of waiting for IE6 share to decrease further before tackling any major site changes. After all, I can wait with the general downward trend in market share; there has to be a point when its awkwardness makes it no longer viable to support the thing. That would be a happy day.

Rough?

November 11, 2009 4 comments

Was it because Canonical and friends kept Ubuntu in such a decent state from 8.04 through to 9.04 that things went a little quiet in the blogosphere on the subject of the well-known Linux distribution? If so, 9.10 might be proving more of a talking point and you have to wonder if this is such a good thing with the appearance of Windows 7 on the scene. Looking on the bright side, 10.04 will be an LTS release so there is some chance that any rough edges that are on display now could be resolved by next April. Even so, it might have been better not to see anything so obvious at all.

In truth, Ubuntu always has had its gaps and I have seen a few of their ilk over the last two years. Of these, a few have triggered postings on here. In fact, issues with accessing the BBC iPlayer still bring a goodly number of folk to this website. That may just be a matter of grabbing RealPlayer, now helpfully available as a DEB package, from the requisite place on the web and ensuring that Ubuntu-Restricted-Extras is in place too but you have to know that in the first place. Even so, unexpected behaviours like Palimpsest seeing every partition on a disk as a different drive and SIL Raid mappings being seen for hard drives that used to live on the main home PC that bit the dust earlier this year; it only happens on one of the machines that I have running Ubuntu so it may be hardware thing and newly added hard drive uses none of the SIL mapping either. Perhaps more seriously (is it something that a new user should be encountering?), a misfiring variant of Brasero had me moving to K3b. Then UFRaw was sluggish in batch but that’s nothing that having a Debian VM won’t overcome. Rough edges like these do get you asking if 9.10 was ready for the big time while making you reluctant to recommend it to mainstream users like my brother.

The counterpoint to the above is that 9.10 includes a host of under the bonnet changes like the introduction of Ext4 hard drive formatting, Xsplash to allow the faster system loading to occur unseen and GNOME 2.28. To someone looking in from outside like me, that looks like a lot of work and might explain the ingress of the annoyances that I have seen. Add to that the fact that we are between Debian releases so things like the optimised packaging of ImageMagick or UFRaw may not be so high up the list of the things to do, especially with the more general speed optimisations that were put in place for 9.10. With 10.04 set to be an LTS release so I’d be hoping that consolidation is the order of the day over the next five or six months but it seems to be the inclusion of new features and other such progress that get magazine reviewers giving higher ratings (Linux Format has given it a mark of 9 out of 10). With the mooted inclusion of GNOME 3 and its dramatically different interface in 10.10, they should get their fill of that. However, I’d like to see some restraint for the take of a smooth transition from the familiar GNOME 2.x to the new. If GNOME 3 stays very like its alpha builds, then the question as how users will take to it arises. Of course, there’s some time yet before we see GNOME 3 and, having seen how the Ubuntu developers transformed GNOME 2.28, I wouldn’t be surprised if the impact of any change could be dulled.

In summary, my few weeks with Ubuntu 9.10 as my main OS have thrown up no major roadblocks that would cause me to look at moving elsewhere; Fedora would be tempting if that situation were to arise. The irritations that I have seen are more like signs of a lack of polish and remain peripheral to day-to-day working if you discount CD/DVD burning. To be honest, there always have been roughnesses in Ubuntu but has the lack of sizeable change spoilt us? Whatever about how things feel afterwards, big changes can mean new problems to resolve and inspire blog posts describing any solutions so it’s not all bad. If that’s what Canonical wants to see, they might get it and the year ahead looks as if it is going to be an interesting one after a recent quieter period.

Evoluent Vertical Mouse 3 Configuration in Ubuntu 9.10

October 31, 2009 5 comments

On popping Ubuntu 9.10 onto a newly built PC, I noticed that the button mappings weren’t as I had expected them to be. The button just below the wheel no longer acted like a right mouse button on a conventional mouse and it really was throwing me. The cause was found to be in a file name evoluent-verticalmouse3.fdi that is found either in /usr/share/hal/fdi/policy/20thirdparty/ or /etc/hal/fdi/policy/.

So, to get things back as I wanted, I changed the following line:

<merge key=”input.x11_options.ButtonMapping” type=”string”>1 2 2 4 5 6 7 3 8</merge>

to:

<merge key=”input.x11_options.ButtonMapping” type=”string”>1 2 3 4 5 6 7 3 8</merge>

If there is no sign of the file on your system, then create one named evoluent-verticalmouse3.fdi in /etc/hal/fdi/policy/ with the following content and you should be away. All that’s need to set things to rights is to disconnect the mouse and reconnect it again in both cases.

<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<deviceinfo version=”0.2″>
<device>
<match key=”info.capabilities” contains=”input.mouse”>
<match key=”input.product” string=”Kingsis Peripherals  Evoluent VerticalMouse 3″>
<merge key=”input.x11_driver” type=”string”>evdev</merge>
<merge key=”input.x11_options.Emulate3Buttons” type=”string”>no</merge>
<merge key=”input.x11_options.EmulateWheelButton” type=”string”>0</merge>
<merge key=”input.x11_options.ZAxisMapping” type=”string”>4 5</merge>
<merge key=”input.x11_options.ButtonMapping” type=”string”>1 2 3 4 5 6 7 3 8</merge>
</match>
</match>
</device>
</deviceinfo>

While I may not have appreciated the sudden change, it does show how you remap buttons on these mice and that can be no bad thing. Saying that, hardware settings can be personal things so it’s best not to go changing defaults based one person’s preferences. It just goes to show how valuable discussions like that on Launchpad about this matter can be. For one, I am glad to know what happened and how to make things the way that I want them to be though I realise that it may not suit everyone; that makes me reticent about asking for such things to be made the standard settings.
