Now for something not Covid-19, which is a rarity lately! A different topic for this blog, but 5G came up in a recent conversation, and what I thought I 'knew' about 5G was: significantly higher mobile data rates were possible (true) 5G is based on higher frequency radio than 4G etc (false) 5G works for far more people even in a crowded spaces (true) towers for 5G must always be close in order use 5G (false) 5G data rates could potentially match/replace fibre optic cable (false) As you can see, turns out what I had thought prior to research, was all a collection of misunderstandings, but when I did research, I found more conspiracy theories than facts.

If you follow car industry publications, there both facts and well recognised predictions that combined, signal a storm for the car industry. Reality: Why The Makers Are Lying. In less than 5 years, electric vehicles will become less expensive than ICE (internal combustion engine) vehicles, and are already significantly less expensive to maintain. Lower cost […]

I recently explored how in 2021, the numbers for EVs don’t really add up yet. One of the key discoveries, was that many sensible people are projecting EVs will reach ‘price parity’ by 2024-5. If this happens consider the trend: Looking deeper, there is every reason those predictions look real, and this will completely turn […]

Right now, without subsidies, buying an electric car does not add up. Currently there is a price premium, and as a result the cars only appeal to those happy to pay a premium to indulge a passion. Buyers are prepared to pay a premium for the environment or the acceleration, but right now, buying is […]

Augmented reality was seen as potentially the way of the future when introduced in 2013. So far, augmented reality through sight has never delivered and people wearing augmented reality glasses are not a common sight. In contrast, people wearing headphones and earphones are everywhere. Augmented sound reality is here (or hear?) and if anything, is growing in significance. This page looks at the topic overall but also includes some specific reviews.

Right now, could be a bad time to invest in technology and buy a new computer. I suggest that, right now, all Apple laptops are in a state of flux, and no Microsoft Surface tablets or laptops make sense. This is all due to the ‘ARMs race to new computer architecture, as an upheaval in […]

Episode 1 stated now could be a bad time to invest in technology and buy a new computer. Apple has announced they are moving to ARM CPUS, which will mean replacing their products, and this episode explores why it is so critical to Microsoft that they also move to ARM, and what the multiple technology […]

I recently researched 5G, in order to understand what it was all about, and the reality of any possible new health risks. I came to the conclusions that 1) health risk claims are groundless, and 2) there is no logical reason to upgrade devices at this time to get 5G. But that research led to questions on how all the connectivity standards fit together, and how compelling might it be to upgrade devices to get benefits of new Wi-Fi, Bluetooth or UWB?

In theory, and under ideal conditions, an EV road trip with DC rapid charging can be as time efficient as travelling in an ICE vehicle. However, conditions are not always ideal. Some trips take much longer, and others can become problematic. Will EV road-trips ever become as convenient and dependable as traveling by ICE vehicle?

The key specification for EVs so far has been 'range'. But how are the numbers measured, will range specific match reality, and can the number even be compared? It turns out there are even 3 different standards for measuring range, and they give very different answers! Further, why have we moved from 'economy' to 'range'? Is there still even economy with EVs?

This page focuses on a topical question, can the Samsung Z Fold 3 be a viable option for someone who has previously owner Samsung Note phones? Having owned 4 notes dating back to the original, I add my review, and links and selected quotes of other opinions. The page includes my review from the perspective […]

Something completely different. A discussion on how this site is hosted: on wordpress.com. Anyone who has started a "blog" or other site on wordpress.com, may get to wonder, what are the options for upgrading the website? What is the value of the free, personal or premium plans and beyond? What real world benefits are there, and, alternatively, what would you lose and/or gain from moving away from wordpress.com. This is a page discussing being in that situation. If you are not considering having a website, it may be of little interest.

The move from S/PDIF to HDMI ARC failed in bringing even a small revolution, but the introduction of eARC in HDMI 2.1 may now actually allow a major revolution.

There are cases where the rapid evolution of technology means that terms can lose connection with their original meaning.  ‘Crop’ and full frame are clear examples.  Should we go back to the original meaning, or embrace using the original term in ways that evolve further and further from that original meaning?

This is the excerpt for your very first post.

John C Dvorak of suggests in this article that Apple is ready to ditch the Mac.  Is this realistic?  The idea that the Mac is a problem for Apple is something I have suggested in conversation on several occasions, so there are a least two observers, and from different perspectives, seeing that Mac products no […]

Initially, it seems the tech industry is just dumb. You could think: “So they get me to watch adds, and they collect my data. It is not like letting them collect my data is going to cost me anything! It is not like Facebook, Google, Instagram, WhatsApp etc have some way of getting their hands […]

This is part of series of pages I will be adding on things I have learnt as part of building this website, and I will soon try and enable following by topic (when I get this page working), so people can separately select notification on building websites and/or population or other issues, without being notified of things outside their interest. Standby for that update. Meanwhile this page provides general help on making an animated GIF for a series of images, specific help on a challenge with animated GIFs, and a list of sites with free images as a resource for those building images.

The race to stop CO2, has led to many 'scams' projects involving hydrogen, but it is not always clear who is being scammed: the public, or the proponents of hydrogen projects. What is the attraction behind the obsession with hydrogen? This is a look at the motives, the myths and the facts around hydrogen projects. Spoiler: There are some valid roles for hydrogen, but hydrogen has no role as an energy source, and even any potential role as an energy carrier is highly questionable.

The US military is, for the first time, sharing that they really do have UFO/UAP sightings that they cannot explain. It is easy to underestimate the significance of this revelation. There is even at least the appearance of deliberate efforts to downplay the significance. But this revelation, at some level changes our understanding of the […]

This is an overview of ‘dark matter’ and ‘dark energy’, that was started back in 2016 but published until I was recently asked again. The TLDR; is that no-one knows what dark matter or dark energy are, and it is not even absolutely certain that either exists. In fact, my addition to the official version, […]

I have been exploring electric vehicles. What is needed to make them affordable, and what it is like to live with them. When exploring charging, the charging systems became so complex that I have extracted what I found as its own exploration, which I plan to keep updated as a reference. It currently does need an update for wireless charging, but some information can be found on my exploration of the logistics of charging.
