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

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. See the story at

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

Microsoft surprises MS-DOS fans with remake of ancient text editor that works on Linux “Last month, Microsoft released a modern remake of its classic MS-DOS Editor, bringing back a piece of computing history that first appeared in MS-DOS 5.0 back in 1991. The new open source tool, built with Rust and simply called “Edit,” works on Windows, macOS, and—in a twist that would have seemed unlikely three decades ago—Linux.” Yes, not only is it open source, but it also has a Linux binary file in its release. It feels a bit like the whole world just turned upside down. The interesting part though is that text editing has not really changed that much. The features may have, but it is still plain old ASCII text, so this editor can still work fine over 30 years later. The linked article has, near the end of the article, a link to the GitHub project site, as well as for a Linux Snap package. See

The British VarEVolt battery fully recharges in 18 seconds — and it just got the green light for mass production I know, news about new battery breakthroughs gets quite boring, as we really don't any of them really making a difference on the ground. “The RML Group was granted Conformity of Production certification for its VarEVolt battery on June 2. This government approval signifies that the firm can mass-produce the powerful batteries for EV manufacturers.” So, maybe this one will really happen. There are two possible problems though, one being the grid/charging station capacity, and the other being at what cost. But either way, the big disadvantage for those needing a charge long the road (not those charging overnight at home) has been the charge time. First prize is always being able to top up at home (cost and convenience). See

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

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).

ZorinOS is a worthy consideration for Windows users newly moving to Linux The linked article is from a Windows user's perspective, moving to Linux. The timing is good as many are faced with working hardware, but which is not compatible for Windows 11. ZorinOS is an Ubuntu-based distro, meaning there are tons of support and advice on the Internet for anything that may need solving. It will also install and run most Windows software, using Wine (I seem to recall that is built in, so double-clicking on an EXE file, should just run). See

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. See

Anker’s Soundcore Sleep earbuds finally feature active noise cancelling - At a Price “Anker has announced a new version of its wireless sleep buds that could be even more effective at delivering a peaceful slumber by blocking out disturbing noises using active noise cancellation. Previous versions of the Soundcore Sleep earbuds blocked external sounds passively using just a snug fit inside the ear, but the new Sleep A30 finally add ANC while still offering enough battery life to last the night.” So, yes, this revision now really seems to tick all the boxes, but the price has also gone up quite a bit (53% in fact). I suppose, though, if these could also be used as your main earbuds then it is not too bad. See
