Track Bird Visitors With A Raspberry Pi And A USB Mic “Avian Visitors is a lovely project by Teddy Warner that uses a Raspberry Pi and microphone to keep track of which birds have been visiting your home, and creates a colourful illustration of recent visitors on top of it all. It reports on a web interface of its own making, but what really takes things to a new level is an optional, stylish E-Ink panel that shows the last 24 hours’ worth of visitors at a glance in a collage.” The colour E-Ink display showing the birds is a really nice touch. There is quite a bit of potential for this project, and one could just start off with the identification before going for a display. See #birds #opensource #technology image

I turned my security cameras into AI assistants with open-source LLM Vision “LLM Vision is a free, open-source Home Assistant integration that lets an AI model examine the images from your cameras and describe what is happening in those images. LLM Vision doesn't replace systems like Frigate; it builds on top of them. Instead of just getting a notification that a person is detected, the AI model can describe what the person is doing, whether they're carrying a package, which direction they're going, whether they're doing anything unusual, and even describe the person and what they're wearing.” In 2026, we should not still be rewinding for hours through video from cameras to spot the issue we are looking for. Imagine being able to just ask it, is the garage door open, are the trash cans outside still, when was the cat last seen, etc. Key though is to really have a LLM running locally that does the work, saving on bandwidth, ensuring privacy, as well as for when the Internet is not reachable. I only wish I realised all this when I bought a new mini-server and my last graphics card. If I knew how useful it was going to be, having local AI running as a service at home, I would have bought differently. Only my desktop PC has this ability, and it is not running 24/7, and it does other things. See #cctv #opensource #privacy #technology image

Netflix accounts taken over in South Africa through session cookie hijacking “These cookies allow users to stay logged in to websites or to save items in a shopping cart even after they exit a site. Through these cookies, cybercriminals have found an exploit that has allowed them to access protected private accounts. They are specifically taking advantage of “remember-me cookies”, which help users log in to different websites and platforms on the Internet without having to re-enter their details.” This was a big thing about two years ago and safeguards were built into Chrome (and Chromium) browsers but that really worked when the hosting service implemented those Device Bound Session Credentials (DBSC) protections. Seemingly Netflix has not done this. It seems that many entertainment and media platforms still rely on standard long-lived bearer cookies. Some good practices though for end users are: Log Out explicitly: Closing a tab leaves the session token alive in local storage. Click Log Out on accounts when finished, which sends a revoke request to the server and invalidates the token. Use "Sign out of all devices": If you suspect malware or a compromised browser, use the account dashboard (e.g., Netflix's "Manage Access and Devices" or Google's "Security -> Your Devices") to invalidate all current session keys instantly. Passkeys: Where supported, switch from traditional passwords + long-lived sessions to Passkeys (FIDO2/WebAuthn). Passkey sign-ins rely on public-key cryptography bound to your device's hardware enclave (TPM or security key), making token replication significantly harder for off-device attackers. Unknown links: Don't click on them is this is often how the session cookies are stolen. See #security #southafrica #technology image

Google Search is likely Yahooed now This is a lesson that you are never too big to disappear. I remember the arrival of Google Search (when that was all they did) and how it collapsed Yahoo search from the scene. Googling even became a verb. As big and massive as Google Search was, who can say they still go to the Google search site to search, after ever having asked what they are looking for in most AI services today? Even just a year or two ago, most people would have laughed at you if you told them no-one would be actually visiting the Google Search page today. Just a month ago I used AI to compare available TVs on Amazon Prime Day, and help me arrive at a decision to buy a new TV. It was a more intuitive and interactive process than doing a plain search. The difference I suppose is, people know Google Search is dumb search (well apart from paid rankings) whilst AI is perceived to be “clever”. AI is not actually clever, but it is at least a step or two above basic search. So the future battlefield for SEO and adverts will now have to be within AI. I expect the paid accounts will have non/fewer of that versus the masses using free access (the way it has always been). See #ai #search #technology image

Team South Africa wins at NASA space engineering competition “The international finals for the world’s longest-running space engineering competition were held at NASA’s Kennedy Space Centre and the Walt Disney World Resort in Florida from 30 July to 2 August. Team ZA was the only African team in the competition. It was South Africa’s first time entering, and no African team had competed before.” So yes, not a solo win by Team ZA on their own, but it shows the tremendous potential that South Africa has. If only SA could rid itself of the corruption plaguing it still, this potential could be fully realised and innovation could help spur economic growth. We owe this to our youth.

OpenAI is giving ChatGPT free users unlimited text chats “OpenAI is making a big change for ChatGPT users on its free and Go tiers: Starting next week, users on those tiers will be able to have unlimited text chats with the chatbot, according to OpenAI. Right now, you may run into rate limits if you do too many text chats on those tiers, but those limits, just for text, will be going away soon. Next week, OpenAI is also adding a Think button for free and Go users that they can use to access higher reasoning for harder questions.” Which may be great for ChatGPT users, but the important thing is competition also helps push the bar up for other AI services such as Claude (who still has a hard cut-off with a rolling window). My spouse recently needed to start using a pretty complex financial package for a startup business. Normally this would involve me being dragged in, and I'd have to set it up and try to explain how it works (after I've spent time mastering it myself). Well she used free ChatGPT and did everything herself. I'm not saying AI will magically solve everything, but it can do some amazing grunt work. Yes, it can be better to learn how to do everything from scratch yourself, but often you need an outcome to get something productive done. On her own, this would have taken way longer and with a lot more frustration. Like it or not, AI is a useful tool to help us get stuff done. It takes dictionaries and search engines from yesteryear, to new levels of productivity. As I've stated before, I don't think AI is capable of actually replacing humans, and even the AI I use, I either paste into it what I want it to look at, or I authorise every step of changes to be made. I do not trust it to just run wild on its own. It requires oversight. See #ai #technology image

Spam callers face penalties of up to R1,000,000 in South Africa So a few amendments made, but what I really am happy to finally see, is the loophole closed around marketers opting in or not: “Any direct marketer who is not registered on the opt-out registry is prohibited from contacting consumers for marketing purposes”. They have to pay to register, and abide with monthly conditions, and of course there is now potentially a hefty fine too. I suppose the only issue is going to be around “foreign marketing” but so far all my spam callers had seemed to be for South African companies. See #southafrica #spam #technology image

LG Monitors Fill Windows PCs With Adware, and It’s Not Just Recent Displays “If you’re using an LG monitor and you suddenly see blaring ads for McAfee scam protection, it’s not because your PC’s been hacked (or, rather, not hacked by some unknown third party). LG, the maker of popular high-end screens, has been quietly stuffing its current and even past monitors full of adware.” I missed this somehow but heard about it this morning on the Security Now podcast. The big issue is not really the adverts at all, and if it were not for the adverts, no-one would probably have picked up on the tracking issues (thank you adverts!). The privacy policy mentions LG can track device usage data and online activity, including what sites you visit and what activities you do on those sites. That is metadata harvesting, much like WhatsApp does, and users should have been aware of it. Although to be honest, most privacy policy issues only become known once someone has highlighted them. It is also partly an issue with Windows updates and how they just install automatically without any highlighting of changes to a privacy policy. Microsoft has warned LG off of this behaviour, but will that just be the adverts disappearing, or the metadata tracking as well. I'd imagine (my guess here) is that LG was also sharing that metadata with advertisers, like WhatsApp states in their T&Cs as “partners”, so it is not 100% clear how far this all went.

It Seems a Lot Like Dead Internet Has Actually Come True “The infamous dead internet theory was originally a conspiracy that posited that the vast majority of the internet was run by bots and thinking machines. Most accounts you saw online were really bots masquerading as people — all part of some nefarious scheme to control humankind by keeping us isolated and divided. That last part is far-fetched, but the core of the idea — that bots outnumber humans online — is inexorably starting to feel weirdly grounded.” Pretty sad. I remember the first public Internet when bulletin boards migrated onto the new web. It was mostly all human driven with lots of blogs, no adverts, no tracking pixels, and no mobile phones. Everything moves on and evolves, that is true, but today you certainly can't trust opinions or videos that are seen on the Internet. I can't see the Internet going away, but it is going to be very interesting to see what the future of content holds. What I'm seeing, is a hollowing out of many of the big platforms such as Facebook, Twitter (who faked numbers to advertisers), etc. Certainly there are still accounts there, but I see next to none of my real human friends or family posting there. Many have migrated off to instant messaging platforms, and the broader other social media users I see, have moved to decentralised platforms like the Fediverse and Bluesky, and the more extreme are active on platforms like Nostr, Secure Scuttlebutt, and some centralised platforms like MeWe and Reddit. LinkedIn is littered with AI generated motivational business memes. It has all come down to gaming the system that rewards “content”. Like so many things in life, money corrupts. Exciting times, but I'm pretty sure that quality content will still find its niche audiences, and especially for those who want to share and educate others. See #ai #bots #technology image

EskomSePush app transitioned to neighbourhood service disruptions otherwise it would have died This is the story of how the app evolved from being a high demand app to manage the electricity load shedding across South Africa, to something completely different after load shedding went away. The app now helps communities crowdsource issue around their water, electricity and Internet outages, and also has channels for safety, weather, and other news in communities. As I don't use Facebook or WhatsApp I like using EskomSePush as it is highly focussed on my own community and I can mute what is not relevant for periods of time. The closest that it comes to is Telegram, where a community channel could be split into different topics, and each muted if needed. I just have to laugh though at WhatsApp, because although it may be the biggest and most used platform, it really always lags a good year to two years behind its competitors. Sadly so many of its users only seem to use that one app, so have no idea of the benefits of other apps. See #southafrica #technology image

Africa’s most popular phones have a tracking problem and explains where data disappears to "Roughly one in two smartphones sold in Africa is made by a company most buyers have never heard of. Transsion, a Shenzhen-based manufacturer, owns the Tecno, Infinix and Itel brands, which together accounted for about 48% of African smartphone shipments in 2025 – more than 40 million of the 84.4 million handsets shipped on the continent last year, according to Omdia data. New research has decrypted what those phones send back to their maker." Yes, one could say that most phones and software anyway report a lot of usage (metadata) back to other countries and developers e.g. WhatsApp even states this in their conditions that their users must accept. But these phone models go a lot deeper than that, first by baking it into the hardware, and secondly by collecting more granular data. Then there is also the issue of the users data packages being used to constantly transmit this data, even though it is not voice or video data. It is still eating away at users data where many can only afford small data packages at a time. It seems the only way to block this data collection, is to block the domains it is reporting to. This is what I have active on my home network, and it is pretty shocking to see the pages of ad-tracking and malware sites that are being constantly blocked (it is about one page per minute). The ones I see are all app level tracking, and because my wife used WhatsApp, TikTok, Facebook, and similar sites, her phone just fills pages of these blocks being shown all the time. One single minute of sites blocked on my wife's phone See #africa #privacy #technology #tracking image

MeshCore Radio for Social Networking and Disasters with zero Internet required The Boland Amateur Radio Club (BARC) invited me to do this talk on 23 July 2026. HAMNET Emergency Communications provided the Zoom platform. The audience consisted of radio amateurs, citizens, and disaster management. MeshCore is a newer type of license-free decentralised radio network that allows citizens, government agencies including nature reserves, disaster management agencies, and amateur radio operators to all talk together, whether in public channels, directly to each other, or even in private encrypted channels. This is WhatsApp/Telegram/Signal without the Internet. The network is not only useful to make new friends across the city and stay in communication with neighbours, but more importantly it is a resilient network that will stay operation long after the Internet has ceased to work due to a disaster or lengthy power outages. This is achievable through solar-powered repeater nodes at high sites, and the fact that this network is not dependent on any central server or presence, and of course there is no approval or registration to use it. My talk highlights the similarities and differences between MeshCore and Meshtastic networks, and the reasons why such a network is so important to have in place across cities and towns. I highlight two recent outages we've had in the Western Cape where towns lost their electricity supply due to adverse weather conditions, and had their normal communications cut off for up to a week. In this time HAMNET does assist with communications but only from key points. Having a broader MeshCore network available, allows citizens and disaster management agencies to stay in contact with each other for essential services and assistance. The City of Cape Town and Western Cape Provincial Government, recognise the value of having fallback communications, and HAMNET already has emergency radio rooms at both sites, which are kept in operational readiness. We are aiming to have something like MeshCore also officially endorsed by the City and Province, so that citizens can equip themselves with these radios ahead of any potential disasters in the future. We also have some wilderness areas in and around Cape Town which have no cellular phone coverage, such as the top of Table Mountain. These areas are also ideal to have such radio networks operational, as they are easy to deploy, and radio nodes cost around R500 each (whether bought by citizens/tourist, or even available to rent for the day). The talk concludes with a comprehensive Q&A around various topics relating to MeshCore radio. Watch at See #disasters #meshcore #opensource #southafrica #technology image

FokOffMense is South Africa’s spam block and POPIA toolkit Block community-flagged spam on Android, send formal POPIA opt-outs, and monitor breaches — one SA account, no ads. iOS users can use the website, but there is no iOS app yet (probably also because iOS does not allow apps to take control of the dialler, which is why TrueCaller was so broken for me when I had an iPhone). This app actually takes control of the Android dialler (otherwise calls cannot be blocked) and accesses / adds to the blocked numbers list on the phone. It is not a caller ID app so you won't see the names identified of callers, but if the number has been reported by 10 or more other users as spam, it will be blocked (as well as for SMS). You have the option of reporting a number in the app to the community, and you can go even further to file a formal POPIA report, which is mailed out through the app's server, so not from your own e-mail. The 10 number requirement is to stop individuals trying to block their spouse for example from everyone. But looking at the list I see some genuine call centres I need to get calls from (who probably spam non-customers) so it seems you can select those numbers from the Community Shield, or not. There is a free tier to try which gets you 5 POPIA request per month, 5 Community Shields blocks per month, and one e-mail monitor. The next tier is at R29 per month for 45 Community Shield blocks and 5 POPIA requests per month. The Premium tier is R99 per month, and Family tier for R279 per month for up to 5 people. Every plan includes privacy scans, a full exposure report, unlimited spam reports and blocking, and Gmail spam upload and email filters. Whilst TrueCaller will give caller ID and call blocking, and allow reporting into its crowdsourced block list, it has no POPIA reporting, nor privacy scans, exposure reporting, or Gmail spam filtering.

Hugging Face Said Last Week It Was Attacked. An Unreleased OpenAI Model Did It, OpenAI Now Says “OpenAI’s blog post essentially says an evaluation was going on that was intended to test the ability of the models to carry out cyberattacks—benchmarks as they’re called. These instances of the models were running theoretically without internet access, and instead given only the ability to download from a network hosted by OpenAI itself via some unnamed web hosting vendor.” I get that AI models need to suck up data to “learn on” but this just goes to show that it is actively being done by AI vendors. And so much for accusing Chinese AI vendors of learning from US AI models, because is this not exactly what OpenAI has been caught doing themselves here? Is this not gaining access to other AI models, surely not just for fun. But either ways, even if it was trying to find a way to cheat on the AI benchmarks, this is very much case of being caught with your hands in the cookie jar. I really don't believe and country or AI vendor is squeaky clean (didn't OpenAI also just settle a case and pay out authors for stealing the content of their books?). Make no mistake, AI is very useful to us all, but AI vendors must really not cast stones from their glass houses at others. See #ai #security #technology image

Euki Period-Tracking App Actually Keeps Your Data Private "Period tracking is a simple job that plenty of apps can do. But most apps these days—including those that track health data—store information about you on their own servers and sometimes even share that data with advertisers. The Mozilla Foundation has tested several of the most popular period-tracking apps, and it identified one as better than the rest at keeping your data private: Euki." It is really sad when something that tracks personal health metrics has to be specifically protected from oppressive governments. But that is where many are today, and this app at least offers a way to keep that data private and secure (like it should be). The data stays local. Remember anything going to a cloud, where you did not set your own encryption key, is likely not actually private. The objective test is, if you forget your password, and it can be rest or restored for you in any way by the service provider, then it is not your private data. See #health #privacy #technology image

=OpenAI Exec Laments That China Is Giving Away Models So Good That For-Profit Companies Won’t Be Able to Compete “Last week, a Chinese-made large language model called Kimi K3, developed by Beijing-based firm Moonshot AI, burst onto the scene. The open-weight model impressed with early benchmark results, trading blows with some of the most advanced closed-weight ones being developed by the likes of OpenAI and Anthropic — and at a fraction of the cost.” Lest we forget, there is BIG money in oil, pharmaceuticals, AI, etc, and those executives do not like their profits being undercut by free community projects. Big money usually locks users in by glossy adverts and other enticements, and if those fail they can always use scare tactics about hidden Chinese backdoors. It's true that cloud services running AI do require big investments, but when better things come along which are cheaper, the market moves as this is what capitalism is about. And in fact, this is what innovation is about. You innovate, or you become irrelevant. This is often what post offices have found out about as courier companies started overtaking them. The US approach seems to have been about throwing more money and resources at AI, whilst the Chinese appear to have been innovating around doing more with fewer resources. The same goes for open source projects where many local AI models are running on smaller home labs and PCs. This how quantisation, GPU offloading, flash attention, context length tuning, etc all came about. No proprietary AI business can either lay claim to any particular copyright of content as all or most of that content was all sucked up from across the Internet by them in the first place. Open source is about collaborating to solve challenges, and resharing and building on what others have done. Yes not everyone can afford to run a mainframe computer at home, so the business model for AI as a service may well be a valid one going forward. There will be lots of room in the market for “selling AI services” because most people are not going to buy massive GPUs at home and do not want to tweak lots of settings, and the one that Microsoft scores on, is too many users can't decide what Linux distro to install (read: can't choose what AI models to use). OpenAI though would do well by competing better instead of screaming foul at their competitors. Maybe they do need to lighten up on the resource requirements. No city wants to see their dwindling drinking water, or power grid, swallowed by ever more and bigger data centres. I do remember about two to three decades back, when I was a PC programmer, that we had a very expensive IBM mainframe that needed upgrading because of resource constraints with the systems we were running. Then someone had the bright idea to try optimising the source code of the biggest systems. Turns out we saved over 30% on resource usage and no longer had to upgrade the mainframe! Sometimes working smarter is better. Today with digital sovereignty becoming more and more strategic to many countries, I think they will be looking more at what AI models they can run locally themselves. AI is already being weaponised to breach vulnerabilities, and to be weaponised through poisoning sources etc. It is all the more reason why you want to run our own and set your own guardrails in place. Running your own AI also means your company or country data stays local. Is it possible? Yes, of course it is. Before we had Linux, we all thought we had to run Windows to get anything done, but we've realised that was a steel box that was built around us by Microsoft's PR (to protect us from the cancer called Linux). Turned out though it was not cancer after all, it was the dream of having freedom and being in control of our own OS without their telemetry. Hopefully AI never becomes another Microsoft, with only one player dominating the whole market. Right now it is looking good with many AI cloud providers (OK mostly in the USA and China) but at least it is not in just a single country, and we have local AI models doing very well at more specialised tasks. It needs to stay open with the providers competing to provide better services for less. If one or two players fall out along the way because they are just too expensive on resources, then so be it.

Microsoft is losing the battle to protect license lucre. It better get used to the feeling “In Disney movies, if you wish really, really hard for what you want, it happens. In British courts, not so much. Prince Redmondia really, really wanted to stop the evil barons from reselling on-prem Office and Windows licenses, and made a fairy tale argument in court to make it so. Our hero did not get its wish, not then, and not now with the UK Court of Appeals.” I just had to post this, as my very favourite saying was the conclusion of the linked article: be careful what you wish for. That, and of course that Microsoft is so big and dominant, that it has killed off much of the competition that has tried to compete with it, if it did not buy them out. Compatibility is touched on as a reason for people sticking to Microsoft, but I can also add the “network effect” for any very large dominant platform like Meta. In both cases, what users need is common interoperable standards, so that they can have freedom of choice. We need open standards (and not like Facebook embracing open standards, only to then shut that off and lock users in once they had got the network effect in place). As I've repeated so often before, imagine where e-mail would be if there was no open standard! You'd have to open a Gmail account to mail anyone with a Gmail account, then open a Microsoft account to mail anyone using Microsoft mail. That is utterly ridiculous. It is time that social media and documents had proper open standards, and providers compete on the user experience they provide for their product. How does any decent competition for say Facebook, get to compete when all users are locked inside of Facebook? They can't leave Facebook as their friends and family are there. That is the network effect in a closed system. So I don't apologise for my criticism of dominant walled garden enterprises. See image

AI Barometer: the best AI for every job right now because choosing is difficult “Barely a month goes by without an AI laboratory declaring its latest model the smartest ever built. For anyone simply trying to keep up, or trying to pick a tool that drafts a decent e-mail, fixes broken code or turns a prompt into a usable image, the noise is deafening. This is the first instalment of TechCentral’s AI Barometer, a recurring, evidence-based snapshot of which AI models and platforms lead in the tasks people actually use them for. No vibes and no vendor marketing: every verdict below is drawn from public, independently run benchmarks and leaderboards, each chosen because it tests the use case in question. The scores were checked in the first week of July 2026 and, given the pace of releases, some will likely have shifted by the time you read this. That churn is precisely why the barometer exists.” This is certainly something that is needed as the constantly shifting array of choices is just too much for any one person to comprehend. A lot depends on what you want to do, how much VRAM you have, etc. And then there are the myriads of settings that can be applied to a model. This barometer keeps to online cloud models by the looks of it, but it is scenario based which would certainly help those who just want to pick what online service to use. Of course, online also has a choice of subscription vs API usage, and the two are usually costed separately. API usage is often pay as/when you use so you can experiment between different services without lock-in. Although there is a cost to that, is i a lot cheaper than buying a GPU with a lot of VRAM today. The only thing I can say for certain is, there is no one model that is best at everything, and there is no one set of settings that is best at everything when it comes to AI models. It will all be a lot better in another year or two. See #ai #benchmark #technology image
