8?

12th October 2009

It now seems that we have a new version of Photoshop Elements from Adobe for every year unless you’re a Mac user. Version 7 convinced me to splash out and that gained me Camera Raw recognition of my Pentax K10D along with subtly enhanced image processing power that I have been putting to good use to get more pleasing results than I ever got before. What can be achieved by using levels, curves and the shadow/highlight adjustment tool for exposure correction has amazed me recently. Quick selection functionality has allowed me to treat skies differently from everything else in landscape photos, a flexible graduated filter if you like. It seems to work on Windows 7 along with Vista and XP so I plan to stick with it for a while yet. As you may have gathered from this, it would take some convincing to make me upgrade and, for me, version 8 doesn’t reach that mark. All in all, it seems that it is a way of giving Mac users a new release with added goodness after having to stay with 6 for so long; yes, there are new features like autotagging in the image organiser but they just don’t grab me. Given that they already have Aperture from Apple and Windows users seem to get more releases, it’s a wonder that any Mac user would toy with Elements anyway. Maybe, that’s Adobe’s suspicion too.

Running Windows 7 within VirtualBox

12th January 2009

With all the fanfare that surrounded the public beta release of Windows 7, I suppose that the opportunity to give it a whirl was too good to miss. Admittedly, Microsoft bodged the roll-out by underestimating the level of interest and corralling everyone into a 24 hour time slot with one exacerbating the other. In the event, they did eventually get their act together and even removed the 2.5 million licence limit. I suppose that they really need to get 7 right after the unloved offering that was Vista so they probably worked out that the more testers that they get, the better. After, it might be observed that the cynical view that the era making people pay to “test” your products might be behind us and that users just want things to work well if not entirely faultlessly these days.

After several abortive raids, I eventually managed to snag myself a licence and started downloading the behemoth using the supplied download manager. I foresaw it taking a long time and so stuck with the 32-bit variant so as not to leave open the possibility of that part of the process using up any more of my time. As it happened, the download did take quite a few hours to complete but this part of the process was without any incident or fuss.

Once the DVD image was downloaded, it was onto the familiar process of building myself a VirtualBox VM as a sandbox to explore the forthcoming incarnation of Windows. After setting up the ISO file as a virtual DVD, installation itself was an uneventful process but subsequent activities weren’t without their blemishes. The biggest hurdle to be overcome was to get the virtual network adapter set up and recognised by Windows 7. The trick is to update the driver using the VirtualBox virtual CD as the source because Windows 7 will not recognise it using its own driver repository. Installing the other VirtualBox tools is a matter of going to Compatibility page in the Properties for the relevant executable, the one with x86 in the file name in my case, and setting XP as the Windows version (Vista works just as well apparently but I played safe and depended on my own experience). While I was at it, I allowed the file to run under the administrator account too. Right-clicking on executable files will bring you to the compatibility troubleshooter that achieves much the same ends but by a different route. With the Tools installed, all was workable rather than completely satisfactory. Shared folders have not worked for but that might need a new version of the VirtualBox software or getting to know any changes to networking that come with Windows 7. I plan to stick with using USB drives for file transfer for the moment. Stretching the screen to fit the VirtualBox window was another thing that would not happen but that’s a much more minor irritation.

With those matters out of the way, I added security software from the list offered by Windows with AVG, Norton and Kaspersky being the options on offer. I initially chose the last of these but changed my mind after seeing the screen becoming so corrupted as to make it unusable. That set me to rebuilding the VM and choosing Norton 360 after the second Windows installation had finished. That is working much better and I plan to continue my tinkering beyond this. I have noticed the inclusion of PowerShell and an IDE for the same so that could be something that beckons. All in all, there is a certain solidity about Windows 7 but I am not so convinced of the claim of speedy startups at this stage. Time will tell and, being a beta release, it’s bound to be full of debugging code that will not make it into the final version that is unleashed on the wider public.

An introduction to Wubi

14th July 2008

An introduction to Wubi

The Toshiba laptop that I acquired at the start of the year is a Windows Vista box and it isn’t something with which I want to play too roughly because the OS came pre-installed on it. I still want to continue to see how Vista goes at close quarters so removing it to put Ubuntu or some other Linux distribution on there wasn’t ever going to be an option that I was willing to take either. Neither was the option of setting up a dual booting arrangement using disk partitioning; I have plenty of experience of doing that to set up dual booting machines over the years and I don’t needed any more than what I already have. So, I was happy to leave it as a Windows box and only as a Windows box.

That situation has changed and the cause was Canonical’s decision to go for something novel when it brought out Ubuntu 8.04. The premise is as follows: a Windows style installation that popped an entry in the Windows boot menu that allowed you to fire up Ubuntu without ever having to do disk partitioning or other similar rough play. For those who are less than enamoured with the Linux option, it’s even easy to remove too, as easy any other Windows program in fact. Removal of Linux is very definitely not what I’d do and that’s even without the pain and upheaval of more more customary means for setting dual booting machines. In these days of virtualisation and hypervisor technology, I have my ideas as to what has been used to give us that easy way in.

Being an Ubuntu user anyway, the possibility of having Ubuntu on the laptop and the interesting opportunity that Wubi offered for getting it on there was too tempting for me to give it a miss. A small download from the Wubi website is all that is needed to set things off. You get a number of options up front like where to put the (large) file to be used to house the Ubuntu world and how large you might want it. Setting a user name and password for the thing gets included among other items. The next stage is to download the files to be used to perform the installation. Once that is completed and it took me a few goes to get the whole lot (thankfully, it stores things up to the point where the downloading operation cuts out so you didn’t start from scratch each time; even so, it’s still annoying and could put some off), it is time to restart the computer and boot into Ubuntu to complete the set up of the operating system itself; it is at this point that the familiar very much returns. A reboot later and you are into a world that does its level best to fool you into thinking that Windows is another universe and never existed on that machine at all.

So, a machine that seemed destined only ever run Windows can run Linux now as well. Wubi comes across as a neat and clever way to get a dual booting computer and I hope to leave mine as I now have it. No feathers were ruffled on the Windows side and I saw no sign of any destruction. That makes Ubuntu’s way of doing things a much better option than other distributions that make you go down more invasive routes when creating a dual booting PC. A question remains in my mind. Could this approach take off?

A year in the making…

17th January 2008

It was a year ago that I set this blog in train. Then, I was exploring the possibilities offered by WordPress.com. After some months, I decided that I wanted to make my own decisions rather than have them so I went independent in June. Between those dates, some big launches took my attention: Windows Vista, Office 2007 & CS3 come to mind. All the while, my experience of UNIX, Oracle and other such matters kept growing more and more. In the latter half of the year, I finally made the leap from Windows to Linux on the home computing front, a decision that taught me a lot and one that I don’t regret. Other subjects featured from time to time as well and my musings on web development and blogging made their appearance too. 2007 was a packed year on the technology front and 2008 is only just getting under way. There’s a Vista laptop and I am already picking up ideas for posts, though I am not going to force them out like I might have tried to do last year. 2008 may be a spot more leisurely but I hope that it’s just as interesting.

Desktop.ini on the desktop?

14th January 2008

Being an experienced computer, I set Windows Explorer to display hidden files when using a Windows PC. However, on my Vista-empowered laptop, that causes two desktop.ini files to appear on the desktop, one for all users and one for my user account. And displaying hidden files does not  seem to be something that you can do on a folder by folder basis. With XP, this did not cause hidden files to appear on your desktop like this so the behaviour could be seen as a step backwards. A spot of googling exposed me to some trite suggestions regarding re-hiding files again but deleting them seems to be the only way out. In spite of the dire warnings being issued, there didn’t seem to be any untoward problems caused by my actions. I’ll see if they stay away but episodes like this do make me wonder if it is time for Microsoft to stop treating us like idiots and give us things that work the in which we want them to function. Well, I’m glad that Linux is the lynchpin of my home computing world…

A new laptop

7th January 2008

Having had it on my wish list for a view years, I finally succumbed to temptation and purchased a laptop in the PC World sale, a Toshiba Equium A200-1VO in fact. I reserved it on the web and popped into the nearest store a few hours later. However, while the reservation system worked, the collection did not go as smooth as I had hoped; it seems that the store where I went was not as well staffed as I would have liked and I needed to wait before I was served. Finding the right part of the store was another issued. Nevertheless, service was efficient once the wait was over and I left with the said laptop, a half-price copy of Norton 360 and a network cable.

The laptop comes with an Intel Pentium Dual-Core CPU, 2 GB of RAM and a 120 GB hard drive. The size of the hard drive may not set the world alight and neither, I suspect, will the Intel graphics adapter. Speaking of graphics, the glossy screen might not be to everyone’s taste but its 1280×800 maximum resolution is definitely respectable. Windows Vista Home Premium is the included operating system and a 90 day trial of Norton Internet Security comes too; I’ll wait for that to expire before adding in Norton 360. I am not in a hurry to add software but the Home and Student version of Office 2007 has made its way on their.

As regards perfomance, the machine so far has done what I have asked of without any bother. Even so, battery life is not extensive with a maximum of ninety minutes. For long stints away from a power point, an extra battery might be in order. That would add to the weight as well and, at around 2.5 kg, it isn’t something that I would go carrying on a weekend backpacking trip. Despite those limitations, it will go on getting used and I’ll be seeing how things go from here.

Faster IE7 phishing monitoring

28th October 2007

The standard phishing detection that comes with IE7 really does slow things down when it comes to navigating web pages. In contrast, the option offered as part of Norton 360 is much faster. So much so that you hardly notice that it’s there at all. When I restored IE7 on my PC and ran it for the first time, Norton asked me to be its default fraud detection and I was away from there. Norton 360 offers nothing for Firefox, my preferred and default option but there may be plug-ins that address that need.

Repairing Windows XP

21st October 2007

I have been having an accident-prone time of it with Windows XP recently and have had plenty of reason to be thankful for the ability to perform a repair installation. Here are the steps:

  1. Pop the installation disk into your PC’s DVD drive and reboot the PC.
  2. If you have your PC set it up to boot from DVD’s in its BIOS, then you at least will have to option to do this. You may find that this happens by default but I needed to tell it to do the deed.
  3. Select normal installation from the first menu that is presented to you by the installer.
  4. Accept the licence agreement.
  5. Press R at the next menu and that’ll repair the installation.
  6. Follow all of the menus from there on; it’ll be all the usual stuff from here on in and there should be no need to reactivate Windows or reinstall all of your other software afterwards.

There is a repair option on the first screen (step 3 above) but this takes you into the dark recesses of the command line and isn’t what I was needing. I do have to say that they do leave the required option late on in the installation process and that assumes on users having a risk taking streak in them, something that definitely does not apply to everyone. If your boot.ini file is not well, you may find yourself needing to do the full installation and that wipes the slate clean on you, extending the recovery process.

IE7 on the way up…

9th September 2007

I don’t spend too much time looking at that stats in Google Analytics but I do find it useful to see what people come to see. Another thing that I keep on radar is the browser technologies that visitors are using. Screen resolution is a particular interest of mine. However, browsers and their versions are watched too and I have spotted the ascent of IE7 from where it was; there seems to be a surge in recent times. I am unsure as to the cause for this but it’s definitely happening and Vista take up seems to have noting to do with it.

Command line mapping of network drives

5th September 2007

Mapping network drives in Windows usually involves shuffling through Explorer menus. There is another way that I consider to be neater: using the Windows command line ("DOS" to some). The basic command for creating a mapping goes like this:

net use w: \\yourserver.address

To ensure persistence of the mapping across different Windows sessions, use this:

net use w: \\yourserver.address /persistent:yes

Here’s how to set up a mapping that logs in as a different user:

net use w: \\yourserver.address password /user:you

The above can include domain information as well and in a number of different forms: domain\username is one.

To delete a mapping, try this:

net use w: /delete

List all existing mappings:

net use

This is a flavour of what is available and Microsoft does provide documentation. Issuing the following command will bring some of that on the command line:

net help use
