These are some of my technology writings. I am a firm believer in the value of open source software and the culture of openness and cooperation that surrounds it. So most of my written work today is about open source rather than proprietary products. If you are looking for information about Microsoft products or anything Windows-based, then you are probably in the wrong place – though please feel free to look around anyway, if you have a few moments to spare.
I had a bit of interest in my Linux media servers recently. In fact I recently completed four Linux media or Zoneminder builds. Here are a few snaps… The machines are based on basic Novatech business PC’s. Nothing special. The media server versions have KDE Neon GNU/Linux. This is a very attractive KDE based desktop…
Seems there is quite a lot of buzz about a “new” image format called “WebP” that is seeing increasing use on-line recently. Although it is attributed to Google, WebP was not strictly a Google invention. It was originally developed by On2 of New York as part of its VP* series “Truemotion” video codecs. Google acquired…
Today I had to spread some nematodes around our recently planted Portuguese laurel trees. But before I put the nematodes in water, I thought it would be fun to look at them under the microscope, and possibly take some photos with my recently acquired 26mm eyepiece to µ4/3 camera adaptor. The camera is my little…
For continuous lighting, one needs a light source that has good colour balance, uses power efficiently, is reasonably robust and does not present a health or fire risk. I am also a tightwad – interested primarily in “bangs per buck”. Whilst I love new technology, I am not prepared to pay silly money for it….
This is how I converted three left-over cheapie (£60 for a box of ten, delivered) 20 watt daylight LED flood lights for use in the studio. The basic tools you need:- Vernier or digital caliper, M10 ISO metric taps. Suitable spanner (17mm AF). Bench vice. Electrician’s screwdriver and wire strippers, to make the electrical connections….
I have always been rather fascinated by the fractal-like properties of the romanesco. It really does look like it is not of this planet. SO I thought it would be fun to team up a romanesco, some cheap RGB LED lighting and a couple of broken silver coloured mannequins. Just in case anyone is wondering:…
I thought I’d play a tick on my girlfriend, such that when she came home from work, she’s find it filled with aliens. As it happens I messed it up and fell over something in the hall bruising my leg and spoiling the surprise. Which she thought was all rather silly anyway. But I did…
I decided to have a go at repairing the HF tweeters unit in my vintage Tannoy Monitor Golds. It was a tricky old job. More pictures to follow. Related Images:
More LED experiments – this time using some small daylight LED and a 12 volt DC power supply to light the Dexion racking. Related Images:
I’ve had this old but very chunky Tamron 80-210mm Adaptall 2 telephoto zoom lens since the mid 1980s. Only I noticed that the overall image quality had become rather poor. I wanted to find out why. When I shone a small torch through it, I noticed what appeared to be a haze. Despite several cleans…
Macro shots using an elderly Soviet era 58mm 44-m4 Helios lens and a 10 mm macro ring. Much to my surprise, it seems to work remarkably well, certainly on my little µ4/3 camera. Related Images:
This little project was intended to capture colour-cycling RGB lighting. One of these days I must get around to doing it again and making a rather better job of it. Related Images:
I seem to have accumulated quite a lot of old wrist watches that have no straps (or “bands” if you are American). So I needed to figure out a way of being able to use them. Then I saw these straps on eBay. They are genuine leather and they only cost a few quid a…
My first introduction to the Novatech *16 Series was in the Beginning of October 2009 when I bought one for my mum & put Ubuntu 9.10 64 bit c/w Medibuntu multimedia thus saving eighty-five quid (or more) Microsoft Tax. My mum is in her seventies and she really does not like computers at all. Interestingly, she…
This was actually rather annoying. These days one rather expects wireless networking to work “out of the box”. Anyway, seems the fix is reasonably simple. These instructions are very specific and therefore need to be followed exactly. They assume you are using the 64 bit version of (K)Ubuntu. I’m also assuming you are using Firefox…
IBM is not one of Microsoft’s biggest fans, particularly after it was well-and -truly shafted in the OS/2 fiasco. So it seems very surprising that its subsidiary Lenovo refuses absolutely to provide any refunds for unwanted Microsoft Licenses, thus completely ignoring the Microsoft EULA. 2009-11-26 12:57 Good afternoon Garfield Unfortunately we are unable to advise…
On 2009-11-26, I wrote to Acer UK to establish what its policy was regarding the Microsoft Tax. This was its response:- Hello, Thank you for contacting Acer. Regarding your enquiry, The value would be £33.95 for vista home premium. This can only be refunded within 30 days of purchase and to get it refunded you…
Editor’s note: This article is old and outdated. Blubuntu was eventually fixed in 2010. KDE4 also went on to be really rather good too. That was until they messed it up again with KDE5, but that is showing signs of being rather good now (2018-12-27) too. Seems that Canonical has woken up to the fact…
Editor’s note: this petition dates back to 2009 and can no longer be signed. However, you can still visit the site if you wish. The patent system is misused to restrain competition for the economical benefit of a few but fails to promote innovation. A software market environment is better off with no patents on…
This is a relatively quick and very effective way to beef up your (K)Ubuntu installation. In other words, it’s how to install all your favorite Ubuntu apps all in one go! Note this primarily applies to (K)Ubuntu 9.04 & 9.10 (Jaunty & Karmic), 64 bit versions. For (K)Ubuntu 8.04 please visit earlier (and possibly outdated)…
Firstly, as ever, please back up anything that is important – as you would with any major upgrade on any computer system! Then you can either use the Synaptic package manager or in this instance it is probably quicker to install from a Terminal window. First you need to ensure the system is fully up…
This is the fourth article in a series of case studies illustrating the difficulty one has purchasing a PC in the UK without being forced to pay a “Microsoft Tax”. We use Linux on all our PC’s and have done so for several years. Therefore we do not need, nor should we be forced to…
We eventually did hear back from Laptops direct. Amazingly, its sales team openly admits that it ignores the Microsoft EULA! So nil penguin points! But if there were a category for honesty then it would get plenty of penguins! The emails are in reverse order and since I guess the sales person is just “following…
Rationale At the moment, everyone who buys a PC from a UK supplier has to buy a Microsoft Windows license whether they want it or not. One has no choice, it is included in the price one pays. So, even if you are using one of the many free alternative operating systems such as Ubuntu,…
Minority interest? Yes. Only used by geeks & programmers? Not necessarily… Ubuntu is a minority interest insofar as it only has a fraction of the users that M$ Windows has. Moreover, despite great improvements in recent years, some configuration issues with Ubuntu are still a pain. However I disagree that you need to be a…
