Technology

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.

BBC deliberately breaks its internet radio service

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…

Simple street photography

My experience of street photography is to make oneself looks as insignificant and unprofessional as possible – which comes rather too naturally to me, TBH! 🙂 Kit should be small, light and ideally somewhat battered looking – a “distressed” look that most of my kit usually acquires after a few weeks’ service. No expensive-looking kit…

USB Type D

USB Type D

Having all become familiar with USB C, seems the USB Group has just announced an even newer and faster connection standard, to be known as “USB D”. Of course, like all new Universal Serial Bus connectors, it will be completely incompatible with all previous USB standards. To guarantee incompatibility, the new connectors will be circular….

Multifunction USB rechargeable LED light

Bought a bundle of multifunction USB rechargeable LED lights from a supplier AliExpress. I actually a bought batch of both types shown below because I like them so much. I paid a bit over a fiver each for them. Quite amazing for their size, weight and cost. Tough, water-resistant and rechargeable via USB C, c/w…

More about my new Ultrastar 20 TB hard disk backup system

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,…

UA1101l power storage unit

For my little IT business, the possibility of power cuts is very bad news indeed. So we invested in one of these things –  a “UA1101l” power storage unit. On paper, it stores about 3.6 MJ (megajoules) or 1 kWh (kilowatt hour) in EV (electric vehicle) grade LiFePO4 (lithium iron phosphate) batteries. My tests suggest…

Raspberry Pi Sonos replacement

Sonos alternative

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 us based upon a Raspberry pi 4B c/w 8GiB RAM, a capacitative touchscreen and an external…

BR-9C combined Geiger counter and EMF meter – initial impressions

I just bought a Geiger counter from a seller on AliExpress. Well it’s actually a Geiger counter and EMF (electromagnetic field) meter, all combined into a single device. I have no idea who actually makes these things. There is no branding other than a model number “BR-9C”. Though I did discover that the enclosures used…

Blown lithium battery

A lot of buzz on the interwebs about Samsung mobile phone batteries. Whilst Samsung devices do seem particularly problematic, it can be an issue with lithium polymer batteries generally – especially the super skinny type. They really don’t like getting hot. I confess I documented this repair rather badly but I did remember to capture…

Synthetic stupidity – or one man and his cabbage…

Like quite a few photographers, I have been flirting with AI (artificial intelligence) digital imaging. Regular readers may even have spotted my Synthetic Stupidity gallery dedicated to the fact that at the moment, publicly available AI graphics tools really aren’t particularly good – even though they are quite good fun to play with. In fact…

Brexiteers’ irrational aversion to the Metric System

Puzzles me why Brexiteers still conflate use of International System of Units (SI) with the EU? Or why these people still think that the metric system is some how “not British” and kid themselves that they are being “patriotic” by refusing to use it?  British Engineers and scientists have been pleading with various British governments…

All your base

Today we take a little trip back in time to one of the internet’s oldest and most famous memes: “All Your Base”. AKA “All your base are belong to us“, this internet meme was based on a badly translated phrase from the opening scene of a video game called  “Zero Wing“. The phrase first appeared…

What about WEBP?

JPEG (Joint Photographic Experts Group) format for images has served us well for nearly three decades. But is is essentially a 1990’s format. Today we have better ways of compressing images. The most popular currently is Google’s WEBP (Web Picture) Format. Many modern websites use WebP as its default format for uploaded images that it…

A fully loaded miniature stainless steel router rack

A few folks have asked me what I use to keep our various networking and internet connectivity kit neat and tidy, yet reasonably service friendly. Well, I have to admit that it was rather a muddle for a many years. That was until I decided to make a simple multistorey stainless steel router rack. Moreover,…

TV versus on-line video sites such as Youtube

Some interesting questions arose recently on a forum to which I belong.  Members were comparing conventional broadcast TV with on-line video sites such as Youtube, and asking… What are people watching on YouTube? Are they watching new material ?  Or are they watching old repeats that are be being shown in breach of copyright? Are…

2021 incarnation, simplified yet improved. Note 15 amp PSU module, IEC mains socket and double 2.4A USB module on the top.

Fed up with wall warts?

One of the problems with modern life is the plethora of plug-in mains adaptors or “wall warts” as they call them on the other side of “The Pond”.  Aside from the mess of wires, and the fact that often they are plugged into multi-gang power sockets an heaped on top of one another, building up…

Image processing using FOSS

I belong to several online photography fora. One of the questions that repeatedly pops up is “what image editing software do you use?” and “what alternatives are there to Adobe Photoshop/Lightroom?” In this article, I hope to demonstrate that high quality image processing is perfectly possible using FOSS (free open source software). I will also…

Facebook’s fortunes on the turn…

Social networking platforms come and go. Does anyone remember Myspace? or Bebo? Granted, Facebook has enjoyed a longer run than most. But today saw parent company Meta’s shares plummet by a staggering $226 billion. That’s the biggest one-day loss for any US company, ever. https://www.theguardian.com/technology/2022/feb/03/facebook-stock-shares-meta-mark-zuckerberg This comes on top of news last month that a…
