I’m going to define technolust or technophilia as the almost uncontrollable urge to snap up the latest or most novel technical gadgets. I succumb to this disease frequently, although I do try to keep it under control. I do! Honestly!

I’ve been vaguely wondering about these selfie sticks, the ones where you stick your cell phone on the end of a pole and trigger it by using a bluetooth connection, so when I saw a bluetooth camera trigger in a local shop, I had to buy it. I had to buy it. I had no choice.

Having got it home and played with it for a bit, I now have to find a use for the darn thing! I don’t particularly like selfies and you can only take so many of them, because essentially they are all the one picture with different backgrounds. You could essentially take one photograph against a “green screen” and chromakey in any background you desire.

My particular area of technolust is things related to or containing computer technology. It’s been with me all my life though I didn’t know it until I came across computer technology at home and at work. I had a Commodore 64 computer at home, and at work I worked on the old huge mainframes, mainly IBM ones. But it really blossomed when I came across mini computers, and the early PCs. I had one of the first portable PCs, like the one in the picture.

One mainframe computer I worked on had 256kB of memory and we agonised over how we should divide the address space up between three or four “domains”. Another had a staggering 2MB of memory.

Then at the other end of the scale one PC we had we also upgraded to 2MB of memory, which came on a plugin card which was around 30 – 40 cms long and 10 – 15 cms high. We had to leave the top of the case off to use it!

It’s not always physical things that trigger technolust or technophilia. Before all printers came with network connections they were connected (via a parallel cable usually) to a PC. It could then be shared to others over the network. HP produced a “JetDirect” device which connected the printer to the network either via a cable or a card inserted into the printer itself. I still remember the thrill that I got when I connected over the network to a JetDirect device (which is about the size of a small paperback book) using FTP as if it was a small computer in its own right, which in fact is what the device was.

I’ve got altogether too many computer-related devices in the house. Some I use all the time and others are gathering dust. If I was truly obsessive I could fill the house with devices and possibly go broke, but I haven’t gone to those extremes. So I have a “server” and a “workstation”, and my wife has a laptop. Strictly speaking I have a laptop, but I don’t boot it up very often. It is my wife’s old laptop which I fixed and rebuilt.

Some time ago we got an iPad, which I found amazing – something the size of a magazine, which was able to do much of what the other more conventional computers were able to, and which was run by the touch of a finger (or two!). I also got an Android phone and I fell in love with the thing, so I had to have an Android tablet. Had to. No question!

I love my Android tablet! It’s a rare day when I don’t use it two or three times and often it is more than that. I investigated programming for it, though I don’t have a “killer app”, so most of my programming efforts are uncompleted. I mostly use it for reading ebooks, getting the latest news and to a lesser extent for email and other online web browsing.

I also use it for games. When I go to bed I take the tablet with me and complete a couple of Sudoku puzzles or similar before I go to sleep. Experts advise against this, but it works for me.

Many people these days appear to be afflicted with technophilia or technolust. When a new Apple device is released queues form at the Apple stores worldwide as people try to slake their desire for latest gadget. This is strange as their old devices, which used to be the latest devices at one time, are not rendered useless by the new devices, and transferring personal information to the new device can be challenging, in spite of attempts to make it easy.

Technolust also extends to software. Some people just have to have the latest apps, the latest operating system. The usual justification for such an upgrade is usually justified by the user as a desire for the new features in the new software or bug fixes in the new software.  While I would not advocate never upgrading software, I find such justifications a little weak.

There is a danger that a software upgrade may “brick” a device, that is, it might stop the device from booting up and being used, which is why many people shy away from upgrades. While this is a real concern such happenings are rare and most upgrades go OK. Nevertheless, most users of technology have a horror story  about how things have turned to custard during an upgrade.

I’m what I would classify as a cautious early adopter. For instance, when the new software was released for my phone and tablet, and these devices informed me that the update was available, I waited for a few weeks and followed the news on the upgrade on the Internet. This is almost always a bad idea as long conversations between people who have had trouble (interspersed with odd rare comment “It went OK for me”) doesn’t encourage one to upgrade!

Those who grow up with technology tend to use that technology without giving it much thought. Televisions are part of the environment. Cell phones are part of the environment. Maybe soon 3-D printers will be part of the environment. Smart phones and tablets, while desirable, are not quite so novel to the kids of today. They will no doubt direct their technolusts to other technologies.

I believe that some firm or other once tried to patent the colour yellow, but I’ve not be able to track this down so far. Although this sounds silly, I believe that the firm extensively used the colour yellow in all its adverts and publicity material and believe that people identified the firm’s adverts by the blocks of yellow colour used in the adverts and that a competitor could take advantage of this by using adverts with similar blocks of yellow. One can see where the firm was coming from, of course, but thankfully the attempt failed I believe.

Yellow is, in the societies that I have lived in anyway, associated with sun, well-being, summer and generally good and beneficial things. In subtractive combinations of colours, yellow, along with magenta and cyan are the primary colours. Many computer printers use these three colour. When I was researching this post I found that computer screens use additive combinations and the primary colours are red, green and blue. (“Research” is a fancy name I use for Googling for something – I usually end up at Wikipedia, so ‘caveat emptor‘!) Apparently the reason that there are three primary colours is that the human eye contains three types of cone cells, and each type is most sensitive to one of the ‘primary colours’.

Some animals have four types of cone cells and thus would see four primary colours. According to the Wikipedia article on the subject some human females may have four types of cone cells. Most placental mammals seem to have only two types of cone cells so can only distinguish two primary colours. As Wikipedia says, it would be wrong to suggest therefore the world ‘looks tinted’ to them. It would look normal to them.

I said above that the colour yellow is generally associated with positive things, like summer, warmth and other things. It is however also associated with cowardice, but I haven’t really been able to find out why. This Yahoo Answer is inconclusive, for example. The best answers, in my opinion, relate it to the ‘yellow bile’, one of the four fluids that were assumed to circulate around the human body. It was assumed that one character was determined by the balance of these four ‘humours’.

Hmm, what else about yellow? The centre of an archery target is yellow, although it is often referred to as ‘gold’ for some reason. Interestingly, in the obviously related sport of darts the centre ring is red or black. Rifle shooting, which also uses a target of concentric circles, uses only black and white, with the circles quartered and the inner circles all coloured black, the outer ones being white.

Yellow flags flown on a ship used to indicate that the vessel had a contagious disease on board. A plain yellow flag stands for the letter ‘Q’ in semaphore core and the speculation is that this was used because it was the initial letter for the word ‘quarantine’. The Wikipedia articles says that these days the plain yellow flag is used to indicate that a vessel is free of contagious disease and requests boarding for customs inspection. I had not heard of that change of meaning, but then again, I’ve not had need to raise a yellow flag! The current flag used to indicate contagious is a quartered yellow and black flag which stands for the letter ‘L’ in semaphore code.

In many cases yellow is used to indicate warnings as in ‘yellow alert’. A yellow alert is usually one level below a red alert which is usually the top level of seriousness.  Generally a yellow alert means ‘avoid, take care, and be alert’. The GeoNet site currently shows a yellow alert level for the volcano called ‘White Island’ which is around 50k from the coast of New Zealand. The volcanoes on the mainland are currently quiet. Incidentally if you look closely at the Crater Floor image at the bottom right you will see Dino the Dinosaur quietly monitoring the volcano as he has done for several years.

Animals are often referred to as ‘yellow’ although it might be more accurate to describe them as ‘light brown’. Some birds, however, are definitely yellow and domestic canaries have given their name to the colour ‘Canary Yellow’. The Yellowhammer, introduced into New Zealand from Britain is a handsome bird with a yellow head breast and belly, marked with black, and with a yellowish brown back. They can form quite large flocks and are probably more numerous in New Zealand than they are back in Britain (as are many European species). The American Yellow Warbler is also a fine yellow plumaged bird.

There are some yellow animals and someone has made a collection on this web page. Most appear to be cold blooded or insects, but there are a few ‘yellow’ mammals. The mammals don’t look particularly yellow actually, but the snakes, spiders and crabs certainly are. Some albino animals (eg ferrets) tend to look distinctly yellow at times.

In autumn (fall) leaves on some trees go yellow, while species have leaves that turn red. This is because the chlorophyll which is green is lost in the autumn as the trees prepare for winter. Many flowers, like the buttercup, have yellow flowers and domestic plants like the tulip or the rose have been bred to have yellow blossoms too. Daisies also have yellow centres and I’ve seen speculation that yellow plants are the colour that they are because the pollinating insects are sensitive to that colour, which makes sense, but I’m not sure if that is the whole story, since I believe that most insects’ eyes are most sensitive to ultraviolet. The pollen that the insects inadvertently transfer from flower to flower is often yellow.

Finally to end this ramble through the colour yellow, I’ll just mention that the inanimate world also has yellow chemicals. The element sulphur is the obvious one, though some Chromates, some Iron compounds, and lead iodide are examples of yellow compounds. In addition chemists (and almost any schoolboy) who have put sodium compounds into a flame will be familiar with the deep yellow colouration of the flame that results. It’s often the first step in the analysis of a compound.
