HamClock provides real time space weather, radio propagation models, and other info useful to radio amateurs This is a highly customisable application that draws in all sorts of technical information that can help radio amateurs. Each pane can be changed to show relevant information. What I really like is the frequency / band projections to any specific DX location. One really has to read the manual, though, to get full use out of the app. For non-hams though, it is still a very interesting app, being able to show time and distance to any location, as well as weather conditions at those locations. The app runs on Linux (your desktop, a Raspberry Pi, etc) and is accessed via your web browser (any OS). If it does not start properly, especially on a desktop, just make sure nothing else has already got that network port in use, e.g. in my case SyncThing was hogging it, and I moved SyncThing to port 8083. You can also start HamClock with a '-w port' to specify what web port it should use. To exit the app, or look at diagnostics, etc, you can long-click for 3 seconds on the padlock symbol to get a pop-up actions menu. See

Here's how you can replace Google Photos with a self-hosted Immich server Immich is really very good - I did a video about myself a few months ago, which shows what you can expect from it and what it looks like to use. As the article mentions, it looks very much like Google Photos (the closest look alike I've seen), and it can even work from a Raspberry Pi on the home network (with an external drive connected). Immich is certainly not some clunky looking out of date app. It is really well-designed and does much of what Google Photos does. Have a quick look at my video if you are in any doubt. See

How to Install Arch Linux: A Beginner’s Practical Guide Installing Arch Linux has always been a little more daunting for newer users. This is partly because it offers a little less wizard guidance, and also partly because you want to be super careful especially around what partitions to use or format, or which not to format. I know this because the first few times I even installed Ubuntu, back in the day, my biggest concern always was which partition is which, and am I going to install over something I don't want to lose. I learnt later on to separate my home folder onto a different partition, and to use GParted or KParted to carefully note down exactly which partition was which, before I started. But of course since I installed Manjaro Linux, I've never had to do another fresh installation again (basically one of the benefits that Arch Linux will give you too). This guide actually shows you how to install Arch Linux in a virtual machine, which is probably an excellent way to try the installation out first, and will give confidence for the live installation later. Remember too, with Arch Linux, you'll probably never be doing this ever again, so some effort and time is really worth it. Linux is not Windows, and I've even ported my existing drives across into a brand-new motherboard, and it has worked fine (remember to map your drives using their UUID's as that makes them pretty portable). So why not Manjaro Linux or one of the other Arch Linux derivatives? They are friendlier and easier to install, they are intended to run on their stable editions. So if you are in the habit of wanting to run some more bleeding edge git versions from the AUR, you may find things break with those packages as they often don't find some dependencies they require. Arch typically runs most of those more bleeding edge packages, so dependencies are not such an issue. Still, even if you install Arch Linux in a VM, it will make a great festive season project to play with! For some (many?) Linux users, becoming a full-time Arch Linux user is the pinnacle they want to reach. You'll tell these users apart from others, as they may express crude disdain for Manjaro Linux and other Arch derivatives in the forums ;-). But even if you use Arch Linux, they may also state you should not be using it as a new user… That said, forums are all getting a lot more friendly and helpful today, and there are also lots of Arch Linux users from all experience levels. This is really not such an issue today as it was maybe 5 plus years ago. I'm just mentioning it as those stereotypes do still crop up, but there are really tons of assistance and posts online about solving all sorts of Arch Linux issues. I know, because I use them to solve any issues I encounter on Manjaro Linux too. See

You Can Now Search the Internet With ChatGPT ChatGPT search has been out now for about a month and a half, following a Halloween announcement from OpenAI. With this new feature, the company finally rolled out an official competitor to AI search engines like Perplexity, Google's AI Overviews, and Microsoft Bing (powered by Copilot). OpenAI originally announced its search plans back in July, with a service called SearchGPT. While SearchGPT was a prototype and launched with a waitlist to try it, ChatGPT search took its place, with OpenAI rolling SearchGPT's main features into its new search feature. The feature originally launched to paid subscribers only, but now, all users can access it. We all know that AI can hallucinate, so it is good to now have another good AI search tool that can be used for comparative purposes. Also, for those you actively avoided Google's tool, this will offer a more neutral alternative option. See

Europe’s Starlink competitor is a go 290 IRIS² satellites by 2030 to provide secure connectivity to governmental users as well as private companies and European citizens. IRIS² is an acronym for Infrastructure for Resilience, Interconnectivity and Security by Satellite. The bonuses will be that the service should be fully GDPR compliance, and the German Chancellor should not be spied upon again (https://www.reuters.com/world/europe/us-security-agency-spied-merkel-other-top-european-officials-through-danish-2021-05-30/). In September, FCC chair Jessica Rosenworcel said she wanted to see more competition to Elon Musk’s Starlink, which has already launched some 7,000 satellites since 2018. “Our economy doesn’t benefit from monopolies... every communications market that has competition is strong, we see lower prices and more innovation, and honestly, space should be no exception.” So, yes it is more than just about data sovereignty, it is quite true that more competition usually will also bring better pricing and services.

Some Tips on How to Check if a Screenshot Has Been Photoshopped Well, maybe they should not have given away how to easily fake a screenshot yourself, but still some useful tips to keep in mind.

Star Flash is a universal remote control standard because we have too many proprietary remote controls Too often you have a TV or device where the remote has been lost or broken and there is no easy replacement, or you end up having 5 or 6 different remote controls on the sitting room table. Why, when we have been standardising on USB chargers for many years now? This is not about having a universal remote control like Harmony used to make (see it is an old problem), but rather having a standard work across the devices that need to be controlled by a single universal remote control. The standard requires remote controls to allow voice control, and to use one of three means of wireless comms: Bluetooth, infra-red, and Star Flash. This standard reportedly detects which device a user wants to control, makes the connection, and eases the chore of directing a stream from a set-top box to a display. Device-makers have been told that televisions and set-top boxes must support the standard, and they've quickly complied: local media report that Chinese consumer electronics outfit Konka has already delivered the first Smart TV capable of handling the universal remote. Sometimes a simple idea can make a massive difference to consumers, and this one has been needed a long time ago already. See

Seafile is an enterprise-ready free and open source alternative to DropBox or NextCloud for file syncing and sharing Seafile provides very fast file syncing. Tens of thousands of small files can be synced in a minute. It does what it does very well, without including an entire kitchen sync of extras. Seafile's built-in collaborative document, SeaDoc, make it easy for collaborative writing and publishing documents. Seafile keeps versions for files and snapshots for folders. Users can restore a file or folder to an old version easily. Snapshot for folders is a handy way to protect files against ransomware. Using de-duplication technology, file versions are kept in an efficient way with reduced storage occupation. Seafile supports online editing and co-authoring for office files (including docx/pptx/xlsx) with integrating with Microsoft Office Online Server, OnlyOffice, or Collabora Online server. Seafile also has a built-in preview for videos, audios, PDFs, images and text files. Seafile supports client-side end-to-end encryption to protect your data, which is a unique feature that you can rarely find in other solutions. Seafile WebDAV interface can be used to integrate Seafile with many mobile apps, like Documents, GoodReader, allowing them to access files. This performance is also partly due to its file system not storing plain text format files. Which is one reason why it is much faster than NextCloud. It is fully cross-platform for Windows, Linux, Mac, Android, and iOS clients. On the server side, it will run on Linux or Raspberry Pi. The Community Edition is fully open source. There is also a paid Enterprise addition that has some additional functionality, but the good news is that for up to 3 users the Professional Edition is actually free of charge (requires registration though).

Does your phone yet have a Silicon-Carbon Battery? The biggest change lies in the anode—the part of the battery that stores and releases electrons during charging. Traditional lithium-ion batteries use graphite here, but silicon-carbon batteries replace it with a silicon-infused anode. Why? Because silicon can store up to 10 times more energy than graphite. The result is a battery with higher energy density, meaning more power packed into the same space. But silicon isn’t perfect. It expands and contracts as the battery charges and discharges, which can cause wear and tear over time. By combining it with carbon, manufacturers have stabilized the material, making it both durable and energy-dense. In short, these batteries last longer, charge faster, and take up less space. These batteries can recharge fully in minutes, not hours. For users, that means a quick 15- or 20-minute top-up gives you enough juice to power through your day. Phones like the Realme GT7 Pro, iQOO 13, OnePlus 13, OPPO Find X8 series, Vivo X200 series, and Xiaomi 15 series already have these batteries inside them. Yes, Samsung and Apple are lagging here...

Your brain can grow from reading and learning - e-books offer the same benefit as paper books The number of people who read for fun appears to be steadily dropping. Fifty percent of UK adults say they don’t read regularly (up from 42 percent in 2015) and almost one in four young people aged 16 to 24 say they’ve never been readers, according to research by The Reading Agency. Two regions in the left hemisphere of the brain, which are crucial for language, are different in people who are good at reading and are likely to be shaped by the habit. Clearly, brain structure can tell us a lot about reading skills. Importantly, though, the brain is malleable—it changes when we learn a new skill or practice an already acquired one. Reading is likely to shape the structure of the left Heschl’s gyrus and temporal pole. So, if you want to keep your Heschl’s thick and thriving, pick up a good book and start reading. Reading is the same whether you read an e-book or a paper book. The big difference is e-books are generally a lot more accessible, are cheaper, take up less space, and usually have some form of dictionary for quick word lookups. There is really no excuse not to read: Books are freely available in libraries, many classics are in the public domain, and there are very diverse topics to cover ever possible interest type. Time though is typically the excuse most give, but this is also not very true, if you consider carefully what a 24-hour day looks like. I set aside 30 mins, when going to bed at night, to read. It also has the added bonus of relaxing the mind and readying it for sleep. See
