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.
End of year tends to make one reflect, and look back over the last year or so. As I did so, my “inner six-year-old’s” mind wandered onto the subject of my favourite camera lens. Problem is that I kinda like them all and I’ve had a lot of fun with them. My favourite lens is…
Having discovered that near-infrared images can make even very boring ugly things look quite interesting, I decided to pop out to what is generally reckoned to be the ugliest part of Havant. Amongst Havant’s infamous ugly-spots, Harts Farm Way, is where you can find the the local water treatment works, the household refuse recycling plant…
Well today is Boxing day, and the sun just managed to struggle its way out of the clouds around 14:00. As luck would have it, my variable infrared filter actually arrived from Shenzen late Christmas eve. So, following on from my early IR adventures on Christmas Eve, I thought I’d pop out to our backyard…
It’s Christmas Eve and my old Lumix DMC-GH2 has just been delivered back, Special Delivery, following its conversion to “full spectrum”, by Protech Photographic in Crowborough. Infrared photography is something I have wanted to do for many years. So this year, as a sort of “Christmas present to self”, I decided to have one of…
On one of the photographic fora to which I belong, there seems something of a panic with regard to AI photography taking over the likes of Instagram, Facebook et al. Well, what does or doesn’t get posted to foreign antisocial media websites is a matter of total indifference to me. And even on sites…
These are some rather useful additional applications or features that are not currently in the Debian repositories. However I find them very useful and I don’t consider a full installation complete without them. It is the final part of our three part “Moving to Debian” series. Moving to Debian series… Dedicated to my friends and…
Now here’s something you can’t do with Microsoft Windows – install a fully loaded Debian 13 system in a single command. In this article we are going to install a whole shedload of applications all at once with a single shell command – albeit quite a long one! This is a quick and easy way…
I don’t have a TV licence – I don’t intend to buy one either. We have a nice big roof mounted TV aerial which I have repurposed for much better things. For a start, it receives FM and DAB radio perfectly adequately. We’re only a 35 km crow’s flight from the hefty Rowridge VHF transmitter….
Skip preamble and launch Units Converter applet Another GarfNet software project snatched from the grave, this is a complete rebuild of the original GarfNet Unit Converter. The main feature of the new GarfNet converter applet is that it is bi directional. Whatever “Quantity:” box you use, the conversion will automagically appear in the other box….
Windows 10 officially reaches end of life 2025-10-14. Unfortunately for Windows users, Windows 11 has some rather specific hardware requirements that a lot of perfectly serviceable PCs currently running Windows 10 do not satisfy. Consequently, lots of Windows 10 users are asking me about alternatives to Microsoft Windows. My stock answer these days is simply…
Skip preamble and launch DoF calculator applet now. Welcome to the latest rework of the GarfNet Depth of Field Calculator. It is based on quite an old JavaScript application that appeared on the web back in the mid 1990s. I rewrote and extended it in the mid 2000’s. Consequently, it was looking rather old and…
Skip preamble and launch METAR applet now. This is a modern rework of a very old PHPWeather project that we eventually abandoned nearly a decade ago. I built this new version in PHP/MYSQL pretty much from scratch, albeit with a lot of help from PerplexityAI. Its main emphases are speed and simplicity. Basically it collects…
How do I change my Google password is another of those frequently asked questions that customers regularly ask me. It’s one of those “easy when you know how” things. But it is rather nested away amongst all Googles various other settings. So here’s how to do it… Open a browser and go to: https://accounts.google.com. Log in…
Finally got decent fibre to the property (FttP) broadband here on Hampshire’s new high-speed “CityFIbre” network as retailed by local provider ‘toob’. I immediately took the opportunity to dump the appallingly poor internet provided by a British outfit called Global4, that we’d put-up with for the last decade or so. Which also meant I could…
Question that comes up from time to time amongst the Android users I support is, “How do I change my email password in FairEmail?” Now FairEmail is generally pretty straightforward to setup, and it works with most email providers, including Gmail, Outlook and Yahoo! It also works well if you have email addresses on your…
In this article I will attempt to address issues upgrading to KDE Plasma 6 from Plasma 5 that I have encountered lately. This is not an exhaustive list. But having undertaken a number of Debian 12 (“Bookworm”) to Debian 13 (“Trixie”) upgrades recently, these are the KDE issues that cropped up for me. I thought…
Do you remember Macromedia Flash? Now, thanks to the canny lads and lasses at Ruffle, Flash is back! To celebrate Garfnet’s 30th anniversary, we thought it would be fun not merely to reinstate the Flash presentations we used to host here, Only this time we’ll fix it so that readers can watch them on any…
I’m not a big fan of computer games. Generally I take the view that computers are difficult enough already, without installing software that effectively makes them even more recalcitrant. However, I make an exception for Tux Racer. Originally written back in 2000 by Jasmin Patry, Tux Racer is an open-source winter sports racing video game…
“Shortwave radio recordings” is a small collection of recordings of various HF and VHF transmissions. These have been hanging around since I recorded them using my Icom IC-R20 radio scanner back in the mid-late noughties. I’m not sure how much interest these will be to other people. But considering Garfnet’s 30th anniversary is only just…
Debian version 13, aka Trixie is due to be declared “stable” 2025-08-09. I’ve been using Trixie as “testing” for a couple of years now and have found it very good indeed. So much so that we are already upgrading our Bookworm machines to Trixie. In all cases so far, this has proven a relatively smooth…
I rather like Micro Four Thirds. Currently I have three µ4/3 bodies and a collection of both dedicated AF (autofocus) and adapted vintage MF (manual focus) lenses. Trouble with µ4/3 is that whilst we are very well catered-for in terms of long lenses, there’s a bit of a vacuum in shorter ones. So I decided…
Whilst I am deeply sceptical about artificial “intelligence”, I’m also having quite a lot of fun with it too. Over the last eighteen months, I’ve gone from generating header images for blog articles, ugly images of unpleasant politicians and surreal greetings cards, to creating entire virtual shoots. Today, it also serves as a serious learning…
Question appeared on a forum to which I belong with regard to emulating tungsten lighting with RGB+CCT. To find out, I fitted a good old fashioned Philips “Photocrescenta” incandescent bulb and a Mi-Light FUT-105 LED into a double E27 double bulb holder and mounted the assembly on a standard studio boom arm. The Mi-Light FUT…
What is TOR? TOR, is an abbreviation of The Onion Router, usually written as “Tor”. It is a free and open-source network that enables anonymous communication on the internet by routing users’ traffic through multiple layers of encryption, similar to the layers of an onion. It helps protect users’ privacy, hides their IP address and…
I had a studio photoshoot booked for last weekend. Unfortunately, my model was poorly and it was too late to book another. Consequently, I was in the unusual situation of actually having a free day, whilst also being in an experimental frame of mind. So I thought it might be rather good fun to try…
