CoMaps is a fully open source navigation app that works offline and doesn’t track users “Born out of governance concerns in Organic Maps, CoMaps has been created with a goal of restoring transparency, community control, and privacy-focused navigation. It’s a fully open source navigation app that works offline and doesn’t track users. A few weeks after the project began, CoMaps has officially launched with apps for both Android and iOS.” It will look similar to Organic Maps but some key differences (apart from the governance) are that remappable left button, and some choices to reduce display clutter. I noticed too, there is an optional (off by default) choice to use Google detected Wi-Fi hotspots for assisting in location. See #technology #navigation #opensource

French City of Lyon Kicks Out Microsoft “European countries have been growing increasingly wary of relying on Microsoft for critical government and public sector services. Concerns about data privacy, digital sovereignty, and potential governmental surveillance have led many to question the viability of depending on an American tech giant for sensitive infrastructure.” The point is, this is actually quite possible to do. Whether an organisation invests in its own people, or employs local companies to assist, it can be done. It is the marketing machine of Microsoft that convinces executives that Microsoft is so easy, that pays to certify installers and consultants, etc. The same can be done by governments, just like the UK government established their PRINCE project methodology, which all consultants and training companies were certified against. The same also goes for document formats. There is no reason to be stuck on .docx after so many governments committed to actually using ODF instead. Governments are not helpless, and can set standards to be complied with, and industry will conform if they want contacts. The big benefit for everyone involved is, anyone can freely download fully compliant ODF suites, and they do really work much the same as Microsoft Office does. I know this personally as I was part of a project to ready our own government to transition away from Microsoft in 2007. Yes, that never happened, but the reasons had nothing to do with the technology not working, or workers not being able to use Zimbra mail or LibreOffice. It was all politics and backroom manoeuvring around the IT staff. Such a change though does take guts and drive to implement, and the willingness of someone to stand up to the so-called “norm” of Microsoft. The world not only needs digital sovereignty, it also needs more competition and choices. Such choices do rest on having proper open standards for the formats of data being stored and processed. Vendor lock-in should be a major red flag for any government. See #technology #opensource #France #government

South Korea Brought High-Rise Fire Escape Solutions To The Masses “When a fire breaks out in a high-rise building, conventional wisdom is that stairwells are the only way out. Lifts are verboten in such scenarios, while sheer height typically prevents any other viable route of egress from tall modern buildings. If the stairs are impassable, or you can’t reach them, you’re in dire peril. In South Korea, though, there’s another option for escape. The answer involves strapping on a harness and descending down ropes hanging off the side of the building, just like in an action movie. It might sound terrifying, but these descending lifeline devices have become a common part of fire safety infrastructure across the country.” Interesting that the design works in both directions, so as one person descends, the other side is going up ready for the next person to descend. It is limited to 15 stories high, but it is real food for thought for skyscraper designers regarding better planning for evacuation of taller buildings. The fact is, things do go wrong, and what happens to the people up on 30 plus floors? Many skyscrapers also have sealed windows. It's a bit like planning for the ideal scenarios, and we hope nothing else ever happens. See #technology #escape #fire

EasiShop is a South African comparative groceries shopping service developed by an ex-student from Cape Town "A former Fish Hoek High School learner is using his tech skills to help South African families stretch their grocery budgets. Tinashe Madanire, a 26-year-old student at Stellenbosch University, along with his co-founder Tendai Katiyo, launched a price-comparison website called EasiShop earlier this year. The idea? A simple website where users can track deals, build shopping lists, and find the best prices across major retailers.” This was something I've long thought we've needed. One place to put a shopping list of grocery items together, and then have the prices compared across Pick 'n Pay, Checkers, Woolworths, etc to find where it will be cheapest to buy. It is not yet going to be perfect, as many retailers also offer reward programs, personalised discounts, and many consumers also have additional kick backs through eBucks, GreenBacks, etc as well. Ideally, you'd want to be able to tick these relevant additional discounts too, and to also have Clicks and Dis-Chem added in future. But it is a great initiative and something that is certainly needed. I hope that it is going to continue to grow, and to benefit many local consumers.

I replaced my ISP router with OPNsense months ago, and I don't regret it at all OPNsense can also be fairly simple to set up if you go with the basics (like most home routers offer). But the great thing is you can also deep dive into it and setup separated VLANs and masses of tweaks and rules. What you need to know, though, is that you will need to run it on a separate piece of hardware (just like you'd have bought a router device) and ideally you'd want at least 4 Ethernet ports on it. The minimum is really two ports (a WAN port and a LAN port). My OPNsense device is a Protectli with 4 ports. One is a WAN port, and I have reserved another for a LAN port, and I have the remaining two ports connected as a LAGG interface to my main switch (so it has dual links for load balancing and redundancy). But again, you don't to do this either if you want to keep it simple. What I still want to explore with mine, is using the Haproxy plugin to do my reverse proxying directly on the OPNsense device, instead of in a container on my server. This will mean that some traffic destined for my OpenWebRx device can flow directly from the router through the main switch and to the OpenWebRx device (instead of via the server and then back through the main switch). OPNsense (and PFsense) does mean total control in your hands, and also ongoing updates and patches for many many years... See #technology #opensource #security #routers

Steam Now Has an Overlay Performance Monitor “Steam has added a new performance monitoring tool to its in-game overlay, giving you information about how your games are using your computer’s resources. This should help you spot potential performance problems, although it is currently in beta. This tool shows information about FPS, CPU, GPU, and system RAM usage, making it easier for players to understand their game’s performance and fix issues.” Mileage may vary on this one, as I'm only seeing the FPS right now. For now MangoHUD works better for me, but if you don't have MangoHUD, this is better than nothing. The screenshot I've included shows MangoHUD at the top left, and the Steam performance overlay at the top right. See #technology #gaming image

WUD is a better alternative to Watchtower for Docker updates What's Up Docker (WUD) will notify you of updated Docker container images for installation, just like Watchtower can do, but WUD solves a number of challenges that I have with using Watchtower: 1. Shows a custom descriptive name for images, including database images. 2. This means no time wasted checking which image must be updated. 3. Updates can be run with the click of a button inside WUD. 4. Auto prunes the old images. 5. Can work with more than one remote Docker host endpoint. 6. Numerous notification services supported. 7. Can single-click to see image's change log. 8. Can optionally auto update docker-compose file with new image version. I demonstrate a number of these features, but I did not really go through the menus, as most settings are set using the environment and label variables in the Docker files for containers (which I do show in the video).

This is a good overview of how regex works “Regex is a pattern-matching language; it's a way to expressively describe patterns that match strings (e.g., words or sentences). For example, say you're searching your hard drive for an image called foo, but you cannot remember if it's a JPEG or a PNG. Many utilities make use of regex for searching, transforming, and interacting with text.” You won't be able to just effortlessly compose your own regex after just reading the linked article, but a quick read through will at least help put it in context. It also gives a feel of what regex can be used for. The reason regex persists after many years, despite looking very confusing, is that it is very powerful. With many GUI applications, you could well find regex running in the background to perform the more complex tasks. See #technology #regex

OpenCloud is the lightweight Nextcloud alternative that runs on anything If you are finding that NextCloud is using too many resources, and just packs way more functionality than you need just for file syncing and sharing, then OpenCloud may be the answer. You are not going to have calendar, mail, chat, etc functionality with OpenCloud, but it also does not load a bunch of other services that NextCloud requires to run. It does have file sharing with passwords and expiring access, and interestingly it handles some basic tasks like PDF viewing on the client side. So this will happily run on a Raspberry Pi.

Steam's latest beta build makes gaming on Linux a breeze by enabling Proton for all titles by default Whilst you can still set a specific Proton version per title, for example maybe you want to use Proton GE, this default seems to default to Proton Experimental (from what I observed). This means all Windows games will now show as installable by default. I inadvertently tried this out about 2 days back when I installed Ships at Sea and just hit the install button. I thought it was odd at the time, as I had not set any Proton version for compatibility. Proton Experimental version is not the most stable version as it includes the latest compatibility patches, but I suppose what is nice about it, is firstly it will be the most compatible for most games, and you won't get left stuck on an older version of Proton either, as the experimental version is not fixed by any version number (it's a sort of rolling update).

You could use an M2 SSD in a PCIe adapter instead of a dedicated M2 slot on the motherboard “If you've already stuffed the slots in your motherboard full of PCIe SSDs, you might be wondering what's the best way to add more. While you could buy larger capacities and swap them out, several manufacturers make PCIe add-in cards that can add one, two, or a whole bunch of M.2 NVMe drives to your system.” This looks like a very interesting option. My mother board only has two M2 slots, but the problem is when I use one of them, that eliminates two of my SATA connectors. Plugging an M2 NVMe drive instead into a free PCIe slot, could make a lot of sense. The linked article also shows what sort of performance impact this may have versus the dedicated M2 slot.

6 Free Games With Hundreds of Hours of Content to Enjoy “With the era of $80 games upon us, free games seem more appealing than ever. But can a free game really give you as much value as something you paid for? Well, in the case of these titles, not only do they give you a ton of content, but they even outstrip many paid games in sheer value.” I've long been playing (and enjoying) War Thunder, and did not really know about Enlisted, so that may be something new for me to try out.

Samsung Galaxy Watch 7 battery life hammered by Samsung Health Monitor app I noticed about a month or two back that my Galaxy Watch was suddenly no longer getting its two days of use out a battery charge. I do keep my watch usage quite light, and normally have the Wi-Fi off, display set to lower brightness, etc, so 2 days is usually fine. I do use watch with the Sleep For Android app that monitors sleeping heart rate etc, and that does chew about 11-12% during the night, but that has been my normal usage. I thought at first maybe it is the battery ageing, but it is not even a year old yet. But checking the battery usage stats showed that the Samsung Health Monitor app (not the standard Samsung Health app) was chewing the battery by a good 3%, higher than any other app. Rebooting had not helped either. Seeing that app is only used for ECG, sleep apnoea and blood pressure, not of which I had used for quite a while, that app should be idling with no battery usage. I tried to delete the app, but it deleted off the phone but not from the watch at all. It would also not disable properly, nor could I turn off the background usage toggle. In the end, I used the ADB command to manually delete the app. And wow, now I have a full 2 days battery use again, plus a little extra. It shows again what impact badly behaved apps have on hardware. Ideally, this app should not be using any battery power if I don’t have sleep apnoea detection active, or if its parent app on the phone is deleted. #batterylife #samsung #technology

How To Check Disk Health In Linux: A Beginners Guide “Your computer's disk drive stores all your important files. Photos, documents, videos, and everything lives on your disk. But what happens when your disk starts to fail? You could lose everything. Worry not! Linux has built-in tools to check your disk health. You can spot disk-related problems early and save your data.” Smartmontools is a package on Linux that provides tools for monitoring and managing the health of storage devices—such as hard drives and SSDs—using the built-in Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) system found in most modern drives. But other tools are also covered such as badblocks, fsck, and the graphical user interface app GNOME Disks. See #technology #Linux #diskdrives

How much VRAM do games really use in 2025? Why this caught my eye is because I just hit a VRAM limitation this week with my RTX 2060 card. It has been playing games just fine without any issue, but DaVinci Resolve Studio reports an issue with one of the new AI features requiring a minimum of 8 GB VRAM to work. So, this is something to keep in mind when looking for a new GPU. The advice seems to be to not necessarily buy the fastest or latest GPU, but rather go for something lower down the ladder, but with a lot more VRAM. See #technology #GPU

Denmark’s Government Ditches Microsoft for Open Source “Up to half of employees at Denmark’s Ministry of Digital Affairs will be switched to (an unspecified version of) Linux in place of Windows, and move from Office 365 to the leading open source productivity suite LibreOffice. Denmark’s minister of digitisation, Caroline Stage Olsen, confirmed the migration is in progress to Danish media outlet Politiken (paywalled), adding that if all goes well the whole ministry will switch to using open source software by the autumn. Denmark, like many countries, wants to have greater control over its own digital infrastructure, data, and cloud services.” This certainly seems to be a move that is growing in popularity across Europe. It does a bit of effort for any change, but this will likely also mean more investment is local skills and resources, and many governments are prepared to pay a premium for that.

@Alby why did I get a mail saying my lightning channels was closed? I did not close it. It was all configured and working until this morning (I logged in with my browser extension and it showed my SATS balance). Now my SATS show 0. I have a self-hosted Alby Hub running 24/7 on a VPS, and that is fully operational and reachable. Now it shows I must "buy my first channel". I already did buy a channel. It has been operational daily. What is asks for now to buy a channel, is my entire SATS balance. Not understanding this?

Peep show: 40K IoT cameras worldwide stream secrets to anyone with a browser “Security researchers managed to access the live feeds of 40,000 internet-connected cameras worldwide and they may have only scratched the surface of what's possible. The US was the most affected region, with around 14,000 of the total feeds streaming from the country, allowing access to the inside of datacenters, healthcare facilities, factories, and more. Bitsight said these feeds could potentially be used for espionage, mapping blind spots, and gleaning trade secrets, among other things.” After all the previous warnings, and even sites published that show these camera feeds, I can't believe this is still such a big thing. There are essentially two ways to quickly stop this with any of your cameras: 1. Prevent any Internet access for the cameras at all: Put them on a VLAN that has no Internet access, or on a guest network that has Internet disabled, and make sure UPnP is disabled on your router (that automatically opens firewall ports), etc. 2. Log into each camera and change the default password or set a password. The problem is most of these cameras come with an enabled API, and also a default username and password (which are known). It is clear that too many people are just bringing home any old IP camera or IoT device and plugging them in on their home (well in many cases work too it seems) networks. Yes it may work fine, but it could be punching holes through your firewall. This is not malicious really, as some devices try to get time sync from the Internet, or they want to check for updated firmware, etc. But they can expose your video and your network. These IoT devices are becoming a bigger and bigger problem, as default security is just about non-existent (remember Microsoft wanting to keep things simple and enable everything so as not to complicate things for users?), and they often have no way of really getting proper security patch updates either. Unfortunately, as I mentioned in a post about two months back around IoT and security, ease of use and security are diametrically opposed to each other. Security is not easy, and easy is usually not secure... See #technology #security #vulnerabilities

Linux Foundation unveils decentralised WordPress plugin manager “A collective of former WordPress developers and contributors backed by the Linux Foundation has launched the FAIR Package Manager, a new and independent distribution system for trusted WordPress plugins and themes.” An interesting development. Something like this is needed, and maybe if the other WordPress parties are not managing to get the issues sorted out, this may be another way forward. WordPress is probably the most used content management system across the Internet. The biggest weakness, as far as vulnerabilities goes (for most platforms, actually), is the 3rd party plugin system.

OpenAI slams court order to save all ChatGPT logs, including deleted chats This is going to become more and more of a privacy problem in the coming years, mainly because: Millions of people use ChatGPT daily for a range of purposes, OpenAI noted, “ranging from the mundane to profoundly personal.” The other problem is one that the US is causing for the free world. Most of the mainstream (centralised) social media as well as AI tools are controlled by the US. With the US more and more placing restrictions on the freedoms of speech, and legally compelling companies in its jurisdiction to hand over the data of their users (this is not new though as there has long been the PATRIOT and CLOUD Acts), there is more interest in citizens elsewhere in the world to preserve their privacy, protect minorities, defend their rights of association, etc. I very nearly did a post recently about Venice, an AI tool: Venice.ai is hosted on a decentralised GPU computing network provided by third-party companies such as Akash, which operate data centres and GPU cards distributed around the world. This decentralised infrastructure supports Venice's privacy-first architecture by processing user inputs without storing or logging prompts or model responses on centralised servers. Chat records are stored locally on the user's device and can be deleted at any time, while the company only accesses users' IP addresses, which can be masked with a VPN. The challenge was that Venice is legally registered and operates under the jurisdiction of the state of Wyoming, United States. So I left that post undone. It is no wonder that there is a bigger and bigger ground swell towards self-hosting and alternative social media today. I have done hundreds of posts about both of these types of alternatives, and it is good to see them all flourishing. But AI itself is growing quickly, and I hope that we see more alternatives outside of US control as well, as the world does need some balance. You cannot have just one country dominating social media, AI, and other technology when the world is full of a diversity of cultures and beliefs, and we need to create safe spaces for everyone to participate in. It also brings home to me what I was recently reading about in the book 'Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism', that when you are operating on a global scale, you do need to navigate some very difficult, diverse, and challenging waters, and you do need to actually care about all of that if you want to be a global player. The coming year may be an interesting one for technology globally (and maybe even broader than just technology). I still cling to my old mantra: Be careful of what you wish for, because you may just get it. Being a global and caring player in technology, means thinking in the global context, and especially of the cause and effect that will result down the line. South Africa has certainly already experienced this itself. In quite a few ways, South Africa is ahead of what may come to be in the US (not politically, but more around technology). The irony is some companies had headquartered outside of the US for tax purposes, and maybe the same thing will happen for privacy purposes in future... Of course everyone has long had the opportunity to use alternative tools, alternative social networks, etc, so no-one can say they are forced to use anything. We do in fact have freedom of choice, but it is often our own friends and family who shackle us to something. The network effect is one of the most powerful rip currents I know of, that works against individuals and corporations. But like I discovered myself over the last 12 months or so, after switching medical insurance, banks, social networks, e-mail provider, and more, sometimes once you've mad e change you wonder why you did not make the move a few years earlier. The grass is not always greener on the other side, but there are many lawns out there, and sometimes your eyesight just gets too accustomed to the colour and texture of one's own grass (it becomes a box, which you need to think outside of).
