Caveat emptor is undefeated in online shopping
Life, James Hein, Published on 11/03/2026
» It is becoming more common to buy things online. The majority of my shopping, not counting groceries, is now done that way. In the past I've warned about prices that are too good to be true, like a 4TB thumb drive for a few dollars from sites like Temu and AliExpress. There is now a kind of middle ground where the price could be correct and it's coming from, say, Amazon. Recently, even though I had some doubts, I bought a 5TB SSD drive from Amazon for around half of what I'd expect it to be. I did this knowing I can easily send things back to Amazon.
Sabine has the science you're after
Life, James Hein, Published on 08/10/2025
» Sabine Hossenfelder is one of the people I regularly watch on the YouTube platform. She is a physicist but also veers into other areas such as artificial intelligence and quantum computing. For her latest video -- In Which I Lose Faith In Quantum Computing -- she makes a number of interesting observations. In short, apart from some very specific applications, quantum computing, even if it is scalable from current technology, has limited application. It also has the potential of bringing down a number of current companies highly focused on this technology, or at least some of their divisions. Artificial intelligence takes up a lot of the space that quantum computing could do well in, but for the present at least, AI does it better. The next 10 years, or less, will be important to see how both of these directions develop, or not. If you are interested at all in physics, maths and occasionally quantum computing, then Sabine Hossenfelder provides some interesting perspectives.
The hidden dangers of AI
Life, James Hein, Published on 24/09/2025
» There's going to be a lot on artificial intelligence topics this week so let's get started. For the time being, the most common way to leverage an AI product is using a prompt of some kind. To that end, you will see lots of posts on platforms declaring that they have the best god-level prompts for large language models (LLMs). A prompt is something like, "What are the top ten songs from Depeche Mode?", or "Draw me a picture of a frog on a toadstool in the style of Alice In Wonderland with vivid colours". The more detailed and nuanced the prompt, the better the desired outcome tends to be. As with everything in the computer world, there are bad actors looking to take advantage of this.
Android is now the new Apple
Life, James Hein, Published on 10/09/2025
» Some may be wondering why have I used an Android phone up to now compared to, say, Apple iPhone? In the beginning, it was for the following four reasons -- a headphone jack, a removable battery, the ability to insert an SD card for storage and the ability to load a program into the computer. That last part may sound a little strange but a 12GB device with 1TB of storage and a graphics unit built in is a computer now. The "program" loading here means you can put your own operating system on the device and install applications, bypassing the Play Store. So where are we now? No headphone jack, no SSD support, no removable battery and based on a recent announcement, no ability to "side-load" programs any more. In other words, Google phones have now or will soon be turned into iPhones.
Hey influencers, nobody likes you

» I was recently at Stonehenge in the United Kingdom. Apart from the historical significance, it is a huge tourist site. As you might expect there are rules, ropes to indicate boundaries and a well-run system. Enter the Influencer. She was the classic example, with friends, attitude and the only one who crossed the ropes to get that special picture.
The entitlement epidemic rages

» I was recently at Stonehenge in the United Kingdom. Besides the historical significance, it is a huge tourist site. As you might expect, there are rules, ropes to indicate boundaries and a well-run system. Enter the influencer. She was the classic example, with friends, the attitude and the only one who crossed the ropes to get that special picture. The current set of typically self-declared influencers come with a sense of entitlement that is almost scary.
Beware the AI bots
Life, James Hein, Published on 04/06/2025
» I recently joined a Facebook group that supposedly represented Kat Timpf, a regular presenter on the Gutfeld! show. I posted a couple of comments and a couple of weeks later, I received a tag in social media purportedly from Dana Perino, a regular on the Fox show The Five. Initially this was a surprise. Why would a famous TV star want to chat with me? After a few chats, it became obvious something was off. The tag name in Messenger was just Dana Perino but the conversation had a few structural errors, not something a former press secretary would make.
Is your internet speed too slow?
Life, James Hein, Published on 09/04/2025
» How important is a good internet connection? This is one of those how long is a piece of string or what computer should I get questions. Back in the day, it was a huge jump from zero bits per second to a 2400 Baud modem. People and businesses were willing to pay a large sum to get connected because it opened up a new world of possibilities, ranging from not needing to go to the library as often and being able to sell and market products online. When and how often you paid for the next upgrade depended on your use case and the capabilities it provided. The next major jumps in speed were 4800, 9600 and 14400bps and everyone jumped to one of these as a next step. During this period, the mid 90s, the T1 at 1.544Mbps was the imaginary godlike speed we all dreamed about but didn't have money to afford. That speed provided real time video conference calls and was limited to government and large business concerns that typically involved a dedicated screening room. This was also when the concept of data compression started to gain popularity as you could send more with less bits.
Jetsons cars finally take off
Life, James Hein, Published on 26/03/2025
» Some readers will remember the old cartoon The Jetsons. This promised a future with flying cards, robot assistants and helpful computer tools. We have or are getting very close to the robot assistants, and the latest artificial intelligence offerings seem to be the automated helpers. Missing to date are the flying cars. That may have changed with the new Jetson ONE, a single person flying car I saw a demonstration of in a recent video. It looked good, seemed to fly with good stability and landed without any issue. You can find the demos with a simple search. The craft has vertical take-off and landing capability. However, I shudder to think of what thousands of these might look like in the skies above a city without some serious improvements in driving and collision avoidance.
Microsoft's quantum conundrum
Life, James Hein, Published on 12/03/2025
» If you've been keeping up with quantum computer news, you will have seen the Microsoft Marketing announcement on topological q-bits and a potential quantum computer in a few years. I was planning to write about this in some detail, but it turns out the reality may not meet the marketing. Surprising, I know, but the announcement implying Microsoft has q-bit technology ready to go and scale is speculative. They don't have any physical models, just some tests and a theory that has already been challenged by the physics community. It will take a while to go through all the published data, but the Microsoft quantum computer could be decades, not years, in the future, if ever.
