If for some peculiar reason (I’ll come to those later) you want to prevent GNOME from setting the desktop wallpaper, you used to have a relatively easy option. If you search for how to disable the wallpaper setting in GNOME, you will find frequent mentions of the method. Unfortunately it no longer seems to work.

It seems that the GNOME developers in their infinite wisdom have seen fit to ignore any previous setting that allowed you to override GNOME and say “I’ll set the background myself”, and quite possibly no longer have that option available. Well, where there’s a will there’s a way :-

$ sudo zsh
# cd /usr/lib/gnome-settings-daemon-3.0
mv background.gnome-settings-plugin _background.gnome-settings-plugin
mv libbackground.so _libbackground.so
pkill gnome-settings-daemon
gnome-settings-daemon

At this point your terminal will be taken over by the gnome-settings-daemon and it will scroll tons of messages past your nose. If you scroll up, you will see close to the top a mention of being unable to load the background setting plugin. At which point you can use your favourite background setting tool (a word on that later) to set the background.

This is a rather brutal method of disabling this, and is prone to failure when the relevant software packages are upgraded – your favourite package manager is likely to replace the “missing” files for you. So if you’re listening, GNOME developers, please resurrect a sensible method for turning this plugin off!

BTW: You may want to check your favourite background setting tool actually works properly in your environment; I’ve found that in my environment both Imagemagick and xloadimage silently failed, but feh and hsetroot worked fine. This had me puzzled for a moment when I tried the first two!

As to why I want to disable the GNOME wallpaper plugin, there are several reasons :-

  1. I’m difficult and want to do it my own way.
  2. The GNOME background setting plugin has some limitations that are irritating to me.
  3. And I have some rather specialist requirements … stay tuned for more information.

Today the Prime Minister made the “mistake” of naming one particularly famous tax cheat – Jimmy Carr. Of course it is not just him who is a slimy tax cheat – there are also people like Gary Barlow, Howard Donald and Mark Owen. And probably very many others. The rich have always had ways of avoiding paying their fair share of tax, and it is time we started pointing fingers at them and sneering.

There are those who claim it is unfair that these people are being singled out for naming. Actually it is very fair indeed; what might be unfair is that there is not a long list of everyone who is using some dodgy scheme to reduce their tax bill published on the front page of every newspaper.

Apparently Jimmy Carr’s lawyers have released a statement to say that he has done nothing wrong on avoiding tax. That is completely wrong – he has done something wrong. It may be legal but that does not make it moral.

What he has done is only marginally better than hanging around outside a hospital on pay day and mug the next nurse coming out.

If you hang out at the more high falutin’ photographic forums on the Internet, you will sooner or later (and usually sooner) encounter a variation on the theme that somehow film endows a piece of work some extra artistic value, and (the quite possibly true) sentiment that in the art-market that high value photographic art is usually analogue in nature (such as the work of Sally Mann) because somehow the process of working the analogue process adds some sort of artistic value to the final work.

Which is just so much horseshit of course – with the greatest respect to those who prefer to work in analogue methods.

There is a very fuzzy boundary between what is art and what is artisanship; whether or not an object has any artistic value, it can still have added value because of the work the craftsperson has put into a work – a hand knitted cardigan is worth more than a machine knitted one. Although I suppose I should note that if the person doing the knitting is your own granny, it’s a whole different ball-game (and it gets even weirder when your granny was also a professional hand knitter!).

There is no great harm in adding the value of the artisanship to the value of a piece of art; what is harmful is assuming that the artisanship contributes to the quality of the art. It isn’t so.

To use the photograph as an example, an image is sensational by provoking thought and emotion not because it is an 8×10 contact print, but because of the image. You could be looking at the original 8×10 contact print by the photographer, or looking at one of a thousand inkjet prints of a scan of the original film; the artistic value is the same (but not the financial value).

Similarly with any art work that can be reproduced – a painting that can be scanned and printed, a sculpture that can be scanned and manufactured using a CNC machine. Although the original may have the addition of an emotional attachment to the artist, any competent reproduction should still encapsulate the artistic vision that was crafted into the original.

Although far smaller than the original, doesn’t this reproduction of “The Scream” (borrowed from the Wikipedia article) still tell the same story as the original ?

As an another example, good literature is just as much art as the finest painting. Yet we do not question the value of reading from a reproduction – who insists on reading the original of The Ballad Of Reading Gaol and insists that reproductions (i.e. any book) has no value ?

If a reproduction can reproduce the artistic vision of the original, it implies that the true original art work is actually the artist’s vision and what we call the original, is just the first reproduction of the artist’s vision. The artist needs to be a competent craftsperson to reproduce that vision in the medium of their choice and may influence the original vision, but it is still a reproduction.

There is a belief that analogue techniques for reproducing artistic visions have a greater value than digital techniques. Why should this be?

In either case, the original vision is still the same; the artist has merely chosen to choose different crafts to reproduce that vision. And despite the critics beliefs, digital techniques still need a good craftsperson to execute those techniques. It may be that digital techniques are easier (although I believe it is more that they are more available) than analogue techniques.

Today somebody finally woke up and realised that the amount of time that pedestrians get to cross the road at a crossing is ludicrously short. They concentrate on the problem that the elderly have in crossing a road in the short time that the little man shows green.

But they are not the only ones who can have trouble. And it is not just about the trouble in crossing in time.

Why should pedestrians huddle at the edge of the road waiting until they get the chance to rush across the road tugging at their forelocks ? Car drivers may protest that giving pedestrians more priority will slow them down, but come on – it isn’t as if you don’t get there quicker than pedestrians anyway. What is a few extra minutes ?

Car drivers might argue that because they pay so much in motoring taxes that they deserve extra priority on the roads. Well, it’s an interesting argument, but is really totally irrelevant. Taxes of any kind are raised in all sorts of different ways and put into a common pool from which government spending is taken – both central government and local government. And the government decides how much will be spent on roads in competition with all the other demands on government funds.

And roads are not the only costs that motoring causes – there is also dealing with the health issues related to motoring such as accidents and respiratory issues.

Besides which, the way that local roads are funded – and all pedestrian crossings are on local roads – means that a relatively small proportion of the costs is made up of motoring taxes. No council funds come directly from motoring taxes, but from council taxes instead. Which means that pedestrian waiting to cross the road may actually be paying more towards the roads than you think.

Besides which it is not simply about the money, but about simple fairness and safety. In terms of safety, the lights need to be green not just long enough to allow slower pedestrians to cross the road, but also to allow pedestrians who are reasonably close to the crossing to cross the road. And even long enough at cross-roads to allow pedestrians to cross both roads – to do the equivalent of a left or right turn.
