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.
Editor’s update 2026-10-04. We just heard from the developer that the QtDMM version 26.1 was officially released this evening. There are versions for Linux, MacOS and MS Windows, and can be downloaded from https://qtdmm.de/download.html Following on from our recent article concerning how to install QtDMM on modern Debian systems, we just received rather exciting news…
I have always rather enjoyed plugging test equipment into a PC and capturing the readings. Way back in my early days of using GNU/Linux I had a lot of fun with a program called QtDMM. I still have my old £15 bargain-bin Tenma 72-6870 which worked almost flawlessly with QtDMM on Ubuntu, back in 2008….
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…
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…
Considering that internet radio has become quite a hot topic on this site, I thought it might be useful to compile a database file for Yuri Saurov’s excellent and increasingly popular Advanced Radio Player widget for the KDE plasma desktop. This list contains international streams for all the BBC national and local stations. It also…
I like taking photos. Trouble is that I’m a tad trigger-happy with the shutter button. Over the last few decades I have captured around ½ million of my own digital images and about 33,000 scanned from 35mm neg. On top of that there are around 45,000 edited/retouched images – not to mention a thousand or…
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…
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…
Editor’s note: TL;DR Latest streams can be found here. For reasons best known to itself, the BBC decided to close many of its internet radio streams yesterday (2025-01-21). Fortunately there are alternatives. After a bit of scrambling and hacking, I’ve been able to cobble together an updated list of BBC national and local radio stations,…
For an increasing number of Brits, BBC Radio is about the only thing the modern BBC has to offer that might justify its antiquated and much resented television licence fee. Or rather it was up until yesterday (2025-01-21), when sadly 3/4 of its AAC/HLS internet radio streams inexplicably fell silent. I’ve written to BBC Sounds…
It’s quite an exciting time in the FOSS graphics world at the moment. After a long, long wait, GIMP 3.0 is finally at RC1 (first release candidate) stage. Debian 13 (Trixie aka Testing) users have just received the long-awaited KDE Plasma 6 desktop – with full Wayland support. Which I have to say that after…
I’m a big Debian fan and I’m currently running Debian 13, aka, “Trixie” on my main laptop workstation. Currently Trixie is Debian’s “testing” branch. Despite being a test version, Trixie has generally proven very stable and reliable. And we users get all the new stuff very promptly. I’m also rather keen on the KDE desktop,…
I’m often amazed by the money some Hi-Fi buffs spend on their systems. I’m something of a tightwad, and I took a rather different approach. This involves mixed tech – or as I prefer to call it, “appropriate technology“. I run one of these. It used to be an Acer Windows box, but all that…
While the Clownstrike fiasco rumbles-on in the West, and people in our particular part of the planet can’t even purchase a train ticket, it seems both Russia and China are almost completely unaffected. Editor’s note 2024-08-17: Seems we’re not the only site referring to Cloudstrike as “Clownstrike”. Crowdstrike has issued several takedown notices to a…
Today our planet is suffering what appears to be Microsoft’s biggest ever outage. Seems the culprit is a piece of buggy “security” software provided by a company called Crowdstrike. Or is that Clownstrike? It sends Microsoft Windows computers into a never-ending boot loop, from which users cannot escape, without going into “safe mode” and removing…
If like me, you are tired of having your screen cluttered full of stupid ads, and the general enshittification of the Internet by commercial interests, then you may wish to try /etc/hosts file “hostile server blocking”. It’s free and no additional software is needed. This is because your /etc/hosts file part of your computer’s TCP/IP…
I suffered my first hard disk failure way back in 1987. Fortunately I recovered 99% of my data. However, successful recovery required quite a lengthy struggle and a somewhat inelegant bodge. Since then, I’ve held something of a fascination, some might even say an obsession with backup systems. Over the years, I have tried all…
Problem is that memory cards can and do fail – even the expensive ones. And of course the world is littered with fakes. Being a bit of an old skinflint, almost all my memory cards have come from Amazon or similar. But I always add one extra precautionary step to the process between purchase and…
EDITORS NOTE 2025-01-22. BBC changed its streams, yet again. Consequently, most of the BBC of the streams on this page no longer work. New streams that do actually work can be found at:- Internet radio player URLs Following the fiasco at the end of last week, when the BBC killed all its HLS internet radio…
Editor’s note: a list of new BBC AAC HLS internet ratio streams can be found here. Over the last few hours, some new BBC streams have appeared. At the moment I don’t know whether these are official BBC streams or if some public-spirited person is re-streaming. Though I’m pretty sure the ones coming from the…
Editor’s note: a list of new BBC AAC HLS internet ratio streams can be found here. Seems the BBC has decided to make all its AAC HLS streams only available to wealthy people who have Apple or similar devices. And the good old-fashioned “shoutcast” MP3 streams have gone altogether. Seems that if you can afford…
I don’t quite know how I managed it but my personal/business dataset has now grown to around 17 Terrabytes. Most of it is spread across multiple smaller disks. This is becoming increasingly difficult to manage. In fact, we are decommissioning our 4TB drives. This is partly because they are well beyond recommended end of life,…
We’re busy replacing a customer’s ageing Sonos distributed sound system with a Linux Media Server (c/w SAMBA for remaining Sonos kit) c/w these tiny Linux-powered SBCs (single board commuters) as replacements. Granted, this is merely a prototype. This unit is based upon a Raspberry pi 4B c/w 8GiB RAM, a capacitive touchscreen and an external…
