Raspberry Pi Connect is a new service to remote control Raspberry Pis.
You can try it out on your own Pis with a Raspberry Pi ID, check out the documentation here:
RealVNC is still useful too; though I hope they update it soon to work with Wayland on Pi OS 12 'Bookworm'! If you want to get RealVNC working on Pi OS 12, see:

In the second episode of EY-Parthenon’s Real-World Strategy Dialogues – a podcast series by EY Parthenon – Discovery Health CEO Dr Ron Whelan discusses the future of healthcare in South Africa.
Whelan is a trained doctor with an MBA from the University of Witwatersrand and boasts extensive experience in the healthcare industry.
He is also the co-founder of Healthforce, a leading telemedicine player in South Africa.
Whelan begins the interview by explaining how he expects the health industry to evolve in the coming years, due to the increasing prevalence of chronic diseases.
He then outlines how Discovery Health is adapting its business strategy to take advantage of the latest digital technologies.
Whelan also talks about his perspective on universal healthcare in South Africa and how he feels about the NHI.
He then touches on the strategic imperatives he believes are essential for Discovery Health to be successful.
Whelan concludes the interview by offering his thoughts on AI adoption and how it may impact the healthcare industry.
In a statement released by the Democratic Alliance in late April, the opposition party expressed what many people suspect to be the case: the claim that “Eskom may be manipulating the power supply ecosystem to keep the lights on at all costs until May 29”. South Africa has now had an uninterrupted electricity supply for over a month – which, depressingly, is the longest period without load shedding since 2022. Naturally, people are suspicious about the timing – since the general elections are now less than a month away, and it was previously believed that load shedding as an electoral issue was going to cost the ANC badly. So is the ruling party somehow managing to rig the system to keep load shedding at bay until May 29th – after which things will return to darkness as usual?

Wireless communication is awesome! Right? Only problem is that there are many different methods and techniques which all use different frequencies and sometimes require extra hardware. But if you do not want to spend extra money on hardware, then the ESP microcontroller boards offer WiFi and Bluetooth. Those only come with a "short" range though. So in this video I will test ESP-NOW which is a wireless communication method that can be used with the ESP boards. It gets rid of many disadvantages while not needing extra hardware. So let's see what it can do and ultimately push it to the limit by building a crude Walkie-Talkie. Let's get started!

Determine your location to the centimeter around the globe? For everybody, not only for the military? Only with an ESP32 and a decent GPS receiver module? Not possible! Wrong; it is possible by using real-time kinematics. You can even earn money by building a base station and connecting it to a global network (Decentralized physical infrastructure network)!.

This video explores what the Android app looks like, how to use the main screens, and what various settings and menu options it has. It gives a good feel of how you'd use Meshtastic radio communications from the app to control the radio settings and to communicate. I did a previous video that dealt with a non-technical intro to what Meshtastic radio is, and this is well worth just watching first if Meshtastic is completely new to you.
Meshtastic is license-free, so anyone can use it, and has really started picking up in popularity in the last year, so much so, that stock has often not been available for a month or two at a time. It's a really fun way to also connect to neighbours nearby, or keep in contact in the wilderness when out hiking.

Researchers have created the world's first graphene semiconductor. The joke goes that graphene can do everything but leave the lab, but in the last few years, this is no longer true. In this episode we'll see how scientists turned the best conductor known to man into a semiconductor, opening the door to faster, cooler and more efficient computing.
Note: the resulting graphene was doped with pure oxygen within the experiment. Apologies for not explaining that critical part.
Also another correction, I called "Georgia Institute of Technology" "Georgia Tech" , just wanted to clarify that.

AI is everywhere. Is it all it's cracked up to be or is it one big scam? Well, as it is for most things, the truth is somewhere in the middle. In this episode we see how, despite some of AI's useful contributions, the hype has also impacted the tech industry negatively.

Cheap power bank based on li-ion cells, using a PD car charger module.
When I saw this video from Louis Rossmann or this one by Tom, a fellow HAM radio operator, I said to myself: Holy shit! I use these car fuses a lot, and I always expected that they protect my circuits from overcurrent and possible burning, but I never checked if they work. Particularly since I started to work with Lithium batteries capable of delivering huge currents and even burning if you are unlucky, the danger increased dramatically. Do I also have bad Chinese stuff? I am sure you want to know the truth, too. So, let’s check out my fuses from AliExpress and Amazon and compare them with the proper ones from Bosch. And I will show you how you can test yours without expensive gear.

In this episode of the Wide Awake Podcast, I spoke to Gayton McKenzie, who is the leader of one of South Africa’s largest political parties, the Patriotic Alliance.
We discussed former President Jacob Zuma and his new political party called MK. Additionally, we delved into his visit to Orania and his efforts to combat illegal immigration.
However, the main topic we discussed, and the reason I invited Gayton back onto my show, is because on the 19th of February 2024, a girl named Joshlin Smith went missing from her home in Saldana Bay in the Western Cape.
Gayton has played a significant role in the investigation that followed her disappearance and he even met Joshlin's mother and her boyfriend, who are the main suspects in this case!

**v7.1 has already fixed the focus issue within Memories for comments, a day after I posted this video**
Memories is a fast, modern and advanced photo management suite, that installs quickly and easily inside Nextcloud. My video contrasts it with the Photos app that comes with Nextcloud, and highlights some reasons why you may want to use it instead of Photos. This app has face, object, landmark, place, and human action recognition capability through the Recognise app. It's not that obvious, but albums can be shared, and photos commented on, with other Nextcloud registered users using the underlying Nextcloud file commenting system.
Memories is a great way to collaborate and share photos privately with friends and family, and even to share public links to some of your albums. It can even work on a Raspberry Pi hosted in the home.
It also has apps for iOS and Android, which can optionally auto-upload photos into Memories.
By saving/reading titles and descriptions into the photo's EXIF headers means that importing or exporting out of Memories is a lot less of a chore with migrating between photo services.

I have grown from an autistic child who needed weekly lessons from a childhood psychiatrist in order to learn how to make eye contact, into an autistic adult who is flying high in an aeroplane made out of comprehensive coping mechanisms.
The way I have made sense of my life, is to find repeated patterns and groupings of traits, the same as we do for the night sky. There does appear to be a unifying autistic core trait, however, which surprised me:

This is an open source solution that works with inexpensive LoRa radios, and your mobile phone or laptop, to be able to pass messages directly, or in shared channels, between the various nodes with no Internet or mobile phone coverage required.
The intention of this video is to give a non-technical overview of what it could be used for, how it works, and what you can expect from it. This is not a "how-to configure it" or a field demo video. Hopefully the video helps motivate some new users to set up these nodes in their own cities, and thereby help this form of mesh off-grid communication be more effective across entire cities.

Alternate Title: NixOS: Stability on the Bleeding-Edge
One day, as happens now and then with a bleeding-edge rolling release distro, a systemd update reversed my mouse buttons.
The great thing about rolling-release and cutting-edge distributions like Arch Linux, is that you get to be a beta tester, whether you like it or not!
I thought this was the way it had to be on Linux: Stability or cutting-edge features, not both.
But that wasn't right at all, with NixOS you can have everything, everywhere all at once!

Alternate title: Rust's Hidden Purity System
I was taught formal methods at university but these ultra-safe development techniques are expensive, require using unusual external verification languages, and most damning for web and application developers, they slow down iteration.
After graduating and getting a webdev job, I despaired that the safety and guarantees of the formal systems that I had been introduced to weren't available to me as a web developer.
I was going to have to act if I wanted to live in a different world.

Love them or hate them, Jupyter Notebooks have become an indispensable tool for data exploration, analysis, model development and collaboration. In this talk, we'll try to convince those who love them to use them in a way that those who hate them, hate them less.
We'll start by talking about what makes Jupyter Notebooks indispensable, and what makes them awful. We'll also talk about the various ways people use notebooks. As part of this we'll do a whirlwind tour through IDE options, from local Jupyter in your browser through to the many managed cloud-based options available today.
Then we'll describe some of the patterns and tooling you can use to make your Notebooks less awful (perhaps even beautiful!). Some principles we'll discuss are: good coding practice and style (using nbqa and other code quality tools), version control and reviewing (using Github, Jupyterlab git extensions, nbdime, nbdev, and ReviewNB), testing (using nbval, nbmake, testbook), dependency management (virtual environments, requirements files, Docker), and automating your code quality efforts (Github actions).
The ecosystem of tooling for Jupyter Notebooks is growing, with new packages and features being developed to help smooth over some of Jupyter Notebooks' limitations. This review will give you a birds eye view of some of the current tooling your team can adopt to improve the quality of your Notebooks!

Data are continuously generated from diverse areas such data from new paradigms such as network devices, cloud computing, wireless and intelligent systems for communications, wireless sensor network (WSN), financial transactions, environmental monitoring, radio frequency identification (RFID), telecommunication, military surveillance, weather monitoring, Healthcare and medical diagnoses monitoring, electricity usage prediction, and real-time surveillance. In the streaming setting, data is unceasing, potentially unbounded, and continuously evolving with time. A tool that can be used as an extension on the Massive Online Analysis (MOA) framework is River, a Python library. This talk will introduce listeners how to use River to do machine learning on streaming data. River library supports different machine learning tasks, including regression, classification, and unsupervised learning. It also supports tasks such as computing online metrics and concept drift detection. River can be used to build a machine learning pipeline and evaluate the model’s performance on a streaming dataset.

Have you ever tried your hand at GeoGuessr, the online game that challenges you to guess your location from random street views? In my talk, I'll unveil the surprising connections between the problem-solving skills used in this game and the world of hacking and cybersecurity.
My journey started with GeoGuessr, where I noticed how similar the way we think during the game is to the thought processes of hackers and cybersecurity experts. It was like learning to hack the real world without realising it!
During the talk, we'll delve into the fascinating world of seemingly ordinary photos and videos on the internet. I'll emphasise why it's crucial for all of us to be cautious about what we share online. You'll also hear real-life examples of how geolocation, the art of figuring out locations based on clues, has been used to find terrorist compounds and provide crucial evidence in missing persons cases.
But it's not all about risks. I'll also demonstrate how we can harness geolocation skills for positive purposes. Through this research I was able to develop an AI tool using machine learning that can analyse and identify street bollards, a key factor in geolocation.
Join me for this talk, where we'll explore the intriguing connections between a simple online game and the dynamic world of geolocation in cybersecurity.

Session 1:
Title: Data Science and AI as a Discipline: Breaking down the state of AI
Historically, data scientists have been expected to be the be-all and end-all of AI solutions. But we’ve realised how difficult and complex the AI and technology landscape is and we haven’t changed our approach across various aspects from hiring to implementation. This talk aims to bring these problems to the fore and discuss what the future holds for software development professional across the data science and AI value chain.
Facilitator: Daniel Wertheimer
Daniel is a lead data scientist and machine learning engineer at Absa where he leads and supports a global team of data scientists and engineers. He has delivered and supported the delivery of valuable solutions across the bank through collaboration across the entire value chain. Daniel has also been acknowledged globally as a 30 Under 30 Future Data & Analytics Leader.
Session 2:
Title: What the Comrades Marathon tells you about Digital / Agile Transformations
The Comrades Marathon is the largest and oldest ultra-marathon in the world. Every year 20,000 runners line up to subject themselves to 90 (very hilly) kilometers of pain, anguish and mental torture - a lot like organisational transformations. Whilst the Teslas, Amazons and Googles seem to have agility built into their DNA, most of us are like the 'average runner' battling through to finish Comrades in the final hour before cut-off.
The presentation combines human interest stories and statistical analysis from the Comrades Marathon to refute several organisational change management misconceptions; demonstrates how the Comrades Marathon applies to the Agile Manifesto (and how this practically applies back to enterprise transformations); and concludes by 'proving' that anyone can run the Comrades Marathon (and therefore any organisation can have a successful transformation!).
Whether you’re a finely tuned athlete or a comfortable couch potato, this is a talk packed with powerful examples to help prepare and sustain your organisation’s transformation into the digital age.
The talk combines statistical analysis and inspirational stories from the Comrades Marathon to provide humorous, practical and appropriate insights that relate to your enterprise agile transformation. Real data, anecdotes and photos are used to illustrate each point.
· Change management fables versus practical facts
· The importance of getting the pace of change just right
· The importance of goals to drive the transformation journey
· Conquering the most difficult aspects of organisational transformations
· The most important metrics to focus on during organisational transformations
· The role of leadership in organisational transformations

With the advent of cloud based technologies and identity management solutions; as well as the widespread adoption of these technologies by businesses and users has introduced new attack vectors that malicious actors can try abuse. One of these is a new type of phishing, called consent phishing.
In Consent Phishing, an attacker-controlled application requests dangerous or sensitive permissions over a user's account or organisation's tenant. The goal of Consent Phishing is to gain the necessary authorisation (consent) over an aspect or portion of a user's account. The consent grants are managed through an Identity Provider using the OAuth 2.0 framework; examples of these technologies would include Azure, Facebook, and Discord.
This talk will explore the concept of consent phishing and utilise examples of consent phishing in Azure to illustrate the explanation. The talk will focus on both the offensive perspective and the defensive perspective of the attack and its relevant indicators of compromise. The talk will also show a high-level investigation of how other technologies tackle the problem of consent phishing.
=====================================================
As there is space, I will add the following planned format for my talk:
1. Introduction.
An introduction to the talk, highlighting what the traditional phishing vec-
tors - like payload and credential phishing - are, and how consent phishing is
different.
2. What is OAuth?
A high level view of how OAuth2.0 work and how authorisation is given.
Focus will be on defining the different parties in the flow and their roles.
3. What is consent?
Background information for how consent grants work with the OAuth2.0
framework. Also a discussion around how authorisation grants are requested
and given to users or applications. This will include a consent prompt that a
user would receive in this situation.
4. How is this useful?
Tying together the previous sections we will look at what the legitimate
use case is of consent for application. This section will emphasise how this is
extremely useful functionality that is not going to be removed.
5. Turning the good to bad?
Once we understand how consent works and why it is useful we will look
at how easily it can be abused. For example, a bot that deletes spam from an
inbox is generally also able to spam others from the same inbox.
6. How do this fit into the phishing playbook?
Exploring the kind of controls that affects this type of phishing and the kind
of controls that it bypasses. This section will also introduce consent phishing in
Azure and give real world examples of cases where a red team would use consent
phishing.
7. Bringing it all together, making an attack happen.
Pulling together all the aspect of consent phishing to take a high level walk-
through of how a consent phishing attack in Azure could be undertaken.
8. The outcome.
Showcasing a couple different scenarios of a successful consent phishing at-
tack. Including reading user mail, reading files, and higher privileged actions
that can be undertaken, provided appropriate consent is granted. This section
will also discuss what attackers can do from the context of a successful attack,
such as harvesting sensitive information or trying to pivot to an on-premise net-
work.
9. Finding the bad guys, what IOCs we have.
Once an attack has been executed, we will look at the logs that would be
generated. There will be a small switch to a blue team perspective of how to
find consent phishing attacks and the type of indicators that one could look for.
An interesting point here is that some of the Indicators of Compromise that are
provided in Azure logs can be misleading as to the source of compromise.
10. We’ve seen Azure what else?
This section will investigate how different technologies have different ap-
proaches to managing consent with their application. We will look at what
some technologies do better and what others do worse. This section will also
try attribute different potential cases of consent phishing and its targets.
11. Wrapping Up; Is the world burning?
Final thoughts on the presentation so far, reviewing where consent phishing
could be used but also the challenges that need to be overcome in order to
successfully perform an attack. Discussing as to how this is another tool in a
red team’s toolbox and something that a blue team should be aware of.
A few years ago, a new addition to the standard lineup of access control equipment quietly appeared - the humble “No touch” sensor. These mostly replaced physical buttons, the typical use case being letting yourself out from the “inside”, where the “outside” would have some form of control such as a keypad, RFID scanner, biometrics, etc. Naturally if you were already inside, you wouldn’t have to authenticate yourself to leave.
Fast forward to 2020 and “things you didn’t have to touch” were all the rage, so these started popping up all over the place (according to my observations). I was curious as to how they worked, and whether the range could somehow be manipulated. I had a hunch that they functioned by reflecting infrared light of some sort and I confirmed this by buying one and taking it apart. I came up with an idea to brute-force these to open with an external light source, and then high-powered infrared LED behind a lens to extend the range significantly. This was attractive because they are frequently placed on “inside” of glass doors where the “outside” requires authentication, so having a high-powered “no touch blaster” would let you into places you shouldn’t be :)
My initial research revealed that they seem to be more secure than I’d hoped, so I’m now less confident that beating them is even possible, but I have a few more ideas around what could be tried.
At a minimum, this will be a talk about taking a piece of hardware and dissecting it to figure out how it works, and essentially security testing it. General hardware security methodology and my journey from wondering, to opening, to what I learned about the devices. Best case scenario, I find a method that works and talk about the weaknesses and end up with a gadget in my red-team bag of tricks.
Also, the title is “noooooooo touch” with 10x o because the extended range, so I’m _really_ not touching it.

GTC’s Got Talent... well, sort of 🎸🎤🎅
We got The Birthday Singer Jeff Latham and a few others in our paddock to wish you a Merry Christmas.
We hope you enjoy this one.
A hall sensor was added under the rotary dial's face plate to detect when the fingerstop is at it's limit. What's shown is debug firmware running where the white "filament" LED flashes every time the hall sensor detects the finger stop.
Fingerstop limit detection was needed to resolve a dial reliability problem, owing to the way I tried to value engineer the rotary dial's pulse counting switch.
With the Face Plate now being an electrically active board, this crazy phone now has FOUR printed circuit boards: The motherboard, daughterboard, dial faceplate, and the antenna. Yikes.

In this talk I will begin by delivering the "State of Delve" update. In similar fashion to the popular "State of Go" talk I will begin by discussing all of the exciting new features and changes that have happened over the past year, since last FOSDEM. Following that I will go into a live demo showcasing how Delve can leverage Mozilla RR in order to perform deterministic debugging. This talk will begin by introducing users to the concept of deterministic debugging and the power that comes with it. Following that I will launch into a demo showcasing how to leverage this concept to debug an otherwise unpredictable highly concurrent program. Users will walk away with immediate practical knowledge they can begin applying in their day to day debugging.
It's been a year since last FOSDEM and a lot has changed with Delve! I will discuss all the new features and changes that have been implemented in the last year.
Following the "State of Delve" introduction, I will dig into how Delve can be utilized to perform deterministic debugging. This style of debugging enables users to record the execution of their process and "play it back" in a deterministic fashion in order to more quickly and efficiently perform root cause analysis on a bug that may otherwise be difficult to reproduce or track down. This section of the talk will begin by introducing the concept of deterministic debugging and why it is so useful and powerful. Once everyone is familiar with the concept I will launch into a live demo showcasing how to leverage this debugging approach to track down and fix a bug which is hard to reproduce and happens only intermittently.
Attendees will walk away with practical knowledge that they can begin applying to their debugging problems immediately.

The "official" mini-debuginfo man-page describes the topic best:
❮blockquote❯Some systems ship pre-built executables and libraries that have a
special ❮code❯.gnu_debugdata❮/code❯ section. This feature is called MiniDebugInfo.
This section holds an LZMA-compressed object and is used to supply extra
symbols for backtraces.
The intent of this section is to provide extra minimal debugging information
for use in simple backtraces. It is not intended to be a replacement for
full separate debugging information (see Separate Debug Files).
❮/blockquote❯
In this talk I'll explain what it took to interpret support for mini-debuginfo
in LLDB, how we've tested it, and what to think about when implementing this
support (e.g. merging ❮code❯.symtab❮/code❯ and ❮code❯.gnu_debugdata❮/code❯ sections).

This is a talk I did for the 2016 World Domination Summit in Portland Oregon. The idea was to take a new audience from zero to hero on the whole concept of the "How and Why" of getting wealthy enough so that you never have to work again - while you are still young.
This was originally published on the WDS Vimeo page, but not many people are seeing it there.
Since I have seen other people re-posting without permission it here on YouTube and getting millions of views, I thought I would do so myself, since it's my own work!
I've left the Linux world behind. Here are my thoughts, likes, and dislikes after using OpenBSD as a full-time daily driver for over a year and a half.

My 1999 Honda Odyssey Van, "Vanna" is still in brand-new condition - how could this be??
On top of that, she has saved me about $100,000 over the time I have owned her, compared to the average person's car ownership and use patterns.
In this video, I break down the FIVE steps to get these kind of results yourself.

This talk will provide learnings from local government on using open source software to enable and scale research and analytics. Governments have a strong proprietary software focus, with good reason. There is however a grey area where open source and proprietary software clash and it is here where open source excels.
This talk is of interest to anyone who is working in a large organisation, with a proprietary software focus, and wanting to introduce and roll-out open source software.

This is more of an introduction and is aimed at people are new to docker or are still wondering what it is and what some of the paths are to using it in their lives.
We'll cover the basics of what docker is and does and some of the tooling options available to use it in the real world.
Specifically, we'll cover StackFiles, Swarm, Kubernetes, Local and Live use and deployment.
My Producer (son) and I decided to rent a top of the line Tesla Model 3 and head out for a beautiful road trip, as a way of testing out both the car and the rental app/service called Turo.
Why is this related to personal finance and early retirement? Because if you can rent a vehicle easily when you need one (whether it's a cool one like a Tesla or just a workhorse like a van or pickup truck), then you don't need to own one yourself.
Or at least you can get by with just a simple commuter vehicle and rent specialized rigs only when you need 'em.
