Back to Jaunty

I’m so disappointed with Ubuntu 9.10-Karmic Koala-that I decided to start over with Ubuntu 9.04-Jaunty Jackalope. This time I’ve opted for x86; there’s really little benefit making use of the nx6125’s 64-bit architecture.

It’s not an ideal solution but at least standby and hibernation work now. The only significant issue concerned Windows sharing; fortunately MLManley’s blog is really helpful and I was able to browse my network in no time at all.

Le Bandiat

Ferme du Lac by Martin Webster

Ferme du Lac, L'Epinassie by Martin Webster

A series of three watercolours I painted on location last year. They all depict the river Bandiat at L’Epinassie (near Marval) on the Haute-Vienne and Dordogne border. This was my first experience of painting on location and I thoroughly enjoyed myself. It was also the first time I painted a water scene.

I learned a lot more about composition, interpreting the scene, and choosing my palette during the first week of August last year than I expected.

Ferme du Lac – With hindsight, this was quite ambitious and that’s probably why I’m a little disappointed with the result. Whilst I struggled to finish the painting in the early evening light that’s no excuse for overworking the foreground trees and getting the distant trees above the weir a shade too dark.

Le Bandiat (1) – My favourite. Albeit not the strongest composition, I’m really pleased with the moss-covered trees even though I’ve over done their reflection.

Le Bandiat (2) – The last picture in the series. I like the composition most. But once again have overworked the distant trees and opposite bank. I’d like to do this again; fortunately I took many photographs.

Unfortunately, the only painting I’ll be doing this month is with a roller and emulsion!

Dust of Snow

A Winter's Day by Martin Webster

Dust of Snow by Martin Webster

I painted this a decade or so ago in acrylic. I think it was my first piece using this medium. It’s based on an exercise from Alwyn Crawshaw’s Acrylic Painting Course. The image quality isn’t that great; I used my mobile phone. The picture now hangs on the bedroom wall.

Dust of Snow by Robert Frost

The way a crow
Shook down on me
The dust of snow
From a hemlock tree

Has given my heart
A change of mood
And saved some part
Of a day I had rued.

OpenOffice 3 British English Thesaurus

OpenOffice 3 British English Thesaurus

Thanks to The Weekly Whinge I now have a British English thesaurus working with OpenOffice 3 on Ubuntu 9.10. Whinger created an OpenOffice extension using the stock en-gb dictionary and Paul Huffton’s thesaurus from brit-thesaurus.sourceforge.net.


British English Thesaurus.This thesaurus (th_en_GB) is intended mainly for use with OpenOffice, but should also be customisable to use with other projects.

Village in the Snow

Winter Scene in watercolour (after Terry Harrison)

Village in the Snow by Martin Webster

A watercolour painting I completed over the Christmas break. It’s based on work by Terry Harrison. I’m particularly pleased with the sky, which I did using the wet-on-wet technique. Hopefully I’ll find more time for my watercolour this year.

BBC iPlayer on Freesat

BBC iPlayer is now available to watch directly from your TV. All you need is Freesat and a suitable PVR, e.g. Humax Foxsat-HDR.

First, make sure you have the latest firmware. Second, connect and set-up a network connection. Next, change channel to BBC1. Finally, press the red button and type 5483 followed by OK. That’s it.

Edit: Now available on all Sony Freesat TVs with the latest firmware, e.g. Sony KDL-32W5810 (I’m spoiled for choice!) :-)

Installed Ubuntu 9.10 x86

My ailing laptop needed a complete rebuild this weekend. Windows XP wouldn’t install; Ubuntu did… eventually.

I installed Ubuntu x86 this time for convenience. More more niggles than 9.04 though:

  1. Palimpsest says my hard disk is failing. I ran badblocks (destructive mode) for around 6 hours before installing Ubuntu and not a single block was reported/ reallocated. Many Palimpsest false positives are reported on Launchpad.
  2. Google Mail won’t work. I’ve previously written about this. As far as I can tell it’s a problem with my ISP: TalkTalk. I changed the maximum MTU to 1360 at the router. No need to use sudo ifconfig eth0 mtu 1360.
  3. Power management does not work. I’ve not looked into this.
  4. I can’t browse my Windows network. This was fixed by modifying smb.conf , nsswitch.conf, and installing winbind.

Running SqueezeCenter on a Buffalo LinkStation Live, part 2

Running SqueezeCenter on a LinkStation Live

Running SqueezeCenter on a LinkStation Live

I’ve been running SlimServer/ SqueezeCenter for a number of years now on an old Pentium 4 box running Linux. Recently, I decided to simplify things and reduce my carbon footprint by putting SqueezeCenter on a Buffalo LinkStation Live V2. This is the second of a two-part tutorial that explains in some detail the steps taken to achieve this goal.

It should be noted that this isn’t for the faint-hearted because you can “brick” (that is, render your LinkStation useless) if you do the wrong thing. However, with the steps outlined below you should be able to revive your LinkStation since the original bootloader isn’t replaced with a non-standard firmware. Nonetheless, it is your decision to try this and your responsibility if things don’t go according to plan. Before you proceed, do your research thoroughly by reading everything here and visiting the reference sites listed.

In summary, the following needs to be done to get SqueezeCenter working on you LinkStation:

  1. Update the stock firmware to the most recent version;
  2. Unlock the stock firmware using a Java utility;
  3. Set-up ssh, optional files and fixes;
  4. Install Optware for the ARM9 processor, set-up ssh and add some start-up scripts;
  5. Install SqueezeCenter.

The first two steps are addressed in part 1. The remaining steps are done using a couple of simple scripts.

It’s worth noting that performance is not as good as that of a PC, which isn’t really surprising given the processor and memory of the LinkStation, but it is satisfactory with some 500 or so albums (around 6,000) songs. Control through a Squeezebox is responsive with only a brief delay before entering the Music Library, Artists etc. The Web interface is a little slow but quite acceptable (I suspect this has more to do with the SqueezeCenter software that the performance of the LinkStation.)

Set-up ssh and install SqueezeCenter

The following steps are based in part from a instructions on NAS-Central.

What’s required:

  1. A script that will make all the necessary changes to your LinkStation. Download this and save it to your LinkStation’s shared folder, e.g. \\192.168.1.150\share (wget should be available if you installed the addons package with acp_commander.)

Step 9. Using your open telnet session type:

$ cd /mnt/disk1/share
$ wget http://martinwebster.eu/projects/linkstation.sh
$ sh linkstation.sh

Check the output for any errors. You should see something along the lines of:

<abridged>
Successfully terminated.
Creating /opt/etc/ipkg/cross-feed.conf...
Setup complete.

If the script terminated correctly proceed to the next step. Note: next time you access BASH you’ll need to use ssh.

Step 10. Install SqueezeCenter:

$ wget http://martinwebster.eu/projects/squeezecenter.sh
$ sh squeezecenter.sh

Downloading and installing SqueezeCenter takes a while (around 10 minutes) so be patient. Check for errors and then proceed to the last step.

Step 11. Open your favourite Web browser and set-up SqueezeCenter:

http://192.168.1.150:9000/

Follow the start-up wizard and set-up SqueezeCenter, i.e. load your music library and playlists. That’s it!

I’ve not tested this part as fully as I’d like (ideally I’d restore the LinkStation to its factory state and start over) but reckon it works just fine. If you have any problems let me know and I’ll help out. Tested on a LinkStation Live V2 HS-DH500GL.

Introduction to SISP

The aims of the book are to examine the historical background to strategic information systems planning, the rationale behind its development, and the identification of the main principles inherent in it. Particularly, the book focuses on the impact of SISP on both public and private sector organisations. The book is in ten parts.

Background

Although computers are about fifty years old, IT is a much younger phenomenon. Moreover, the notion that IS/ IT is strategic is newer still. The exploitation of IT for strategic advantage began in the early 1970s largely as a response to changing global economic and social conditions and rapid advances in technology. Likewise, IS and IT became the key enablers of truly global trading systems (Drucker, 1993).

Nevertheless, it was not until the late 1980s that IT was considered an essential part of corporate strategy. The strategic opportunities and threats of the 1980s, coupled with cheaper computing power, ultimately led to IT becoming an important support for organisations’ strategies.

However, the pace of change, which influences many aspects of business, both private and public sector, is often difficult to cope with and is seen as a problem area by many chief executives. Furthermore, the importation of private sector management techniques into the public sector, and the accompanying emphasis on sustainable competitive advantage, has proved to be inappropriate to the management of the welfare state (Flynn, 1993).
