I am a massive GNU/Linux fan. I switched to GNU/Linux back in 2007 following Microsoft’s Vista fiasco. Never looked back. Today, all my workstations and server run GNU/Linux. Mostly Debian these days, or some derivative thereof.
Firefox running in Debian with KDE Desktop has a rather annoying bug, where it won’t open geo URI links using OSM (OpenStreetMap). This was doubly annoying for me because I have taken a lot of care to include geo URI links in this site recently. Moreover, OSM is by far my preferred mapping service. Anyway,…
[Jump to gallery | script] These are some almost SooC images BUT cropped square AND with left and right images swapped AND “alignment circles” at the bottom. These 3D square stereograms were captured with my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system…
[Jump to Gallery] As part of my embryonic GNU/Linux digital camera project, I recently built a 3D camera module. Basically its a ELP board, in an aluminium 1590A type stomp box with a short internal USB3 extension lead. This is a small collection of processed images I created while I was testing my 3D camera…
I thought it might be handy to make a small collection of web-based resources for outdoor photography and similar activities. Some of these resources are right here on GarfNet. The rest are dotted around the worldwide web. So I thought it would be helpful to list all these links here, all on a single page,…
[Jump to gallery | scripts] This article documents my first experiments in producing red-cyan anaglyphs. The gallery contains of four near-identical 3D anaglyphs with varying amounts of X & Y offset to compensate for the fact that the cameras on the board don’t quite point in the same direction. One can create anaglyphs in GIMP….
[Jump to gallery | script] These are some almost SooC images BUT with left and right images swapped AND “alignment circles” at the bottom. They were captured with my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system using easily available generic components. Although…
[Jump to gallery | script] These are some almost SooC images BUT with left and right images swapped. They were captured with my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system using easily available generic components. Although the images themselves are unedited, the…
[Jump to gallery | script to add exif] These are some unedited 3D SooC (straight out of camera) 1600 x 1200 pixel stereo pairs (3200 x 1200 pixel overall) from my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system using easily available generic…
Following on from a discussion on a photographic forum who which I belong, an old hobby horse of mine raised its head again. Namely the possibility of building one’s own Debian GNU/Linux digital camera, using Raspberry Pi 5 single-board computer, or similar, and one of the camera modules that’s available for it. Or indeed some…
I suffer dreadful mental blocks at times. I’m also a tad forgetful. To work around this, I use Jaap Karssenberg’s ‘Zim’. This is an excellent indexed, searchable, cross-linkable, exportable, cross-platform note-taking program. Described by its developer as a ‘desktop wiki’ Zim turns effective note-taking from a tedious chore into a simple and routine task. And…
Fora all over the worldwide web are buzzing that Windows 10 reached end of life, c/w cries of “…but, but, my computer won’t run Windows 11“. Whatever shall we do? These fora offer various solutions, almost all involving using more proprietary products of the same large foreign software corporation that caused this problem in the…
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…
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…
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…
