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.
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.
Graphene semiconductors mark new start
Life, James Hein, Published on 17/01/2024
» We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.
Microsoft stock booming on AI run

» It's not a good time to be working for Microsoft, but it is a good time to be a shareholder or executive. Stock is up over 30%, net income is up and the CEO Satya Nadella got a nice 10% raise. Regular workers received no pay rise, or effectively a 5% pay cut due to inflation. Microsoft has rationalised it as pat and generic reasons like a "competitive environment" and the "global macroeconomic uncertainties". In reality, Microsoft is using the money to jump into the AI wave through a multibillion-dollar partnership with OpenAI.
When AI is not smart enough for the job
Life, James Hein, Published on 14/09/2022
» I was wondering what to write about this week and then I saw the Japanese Amazon story and how it relates to artificial intelligence. Labour unions in Japan have been a thing since World War II, but delivery drivers for Amazon Japan were not unionised, until recently.
Protect yourself when online

» A friend of mine, let's call him Dave, wrote to me recently about identity theft. He told me that all of his identifying information like phone numbers, email addresses, old passwords and his usual security questions, were all available on the dark web. He also had a number of notifications of personal information breaches that resulted in fraudulent charges, the need to replace credit cards and attempts to set up fake bank accounts in his name. The latter is used if a hacker is planning to get into your other accounts so they can transfer funds to themselves under your name.
Scams on the rise as inflation bites
Life, James Hein, Published on 06/07/2022
» We start this week with a webserver with extras in a single file that runs on any x86-64 operation system. Enter redbean 2.0. Created by Justine Tunney, it uses the "Actually Portable Executable" that you can read about here, justine.lol/ape.html. When you compile a program to its native binary, in this case x86-64 code, and don't call any external code, then the only difference between a Windows and a Linux would be the file format. If you can solve this, then it could run on any platform. To do that you need Cosmopoliton libc because any real program needs to make some calls, in this case the standard C ones. So, with Cosmo and the APE format, you can write a C program and compile it to a single file that will load and run on six very different operating systems and the same binary can also be booted directly from the PC BIOS. It's not perfect, but any programmer would be scratching their heads by now. Pause for techie amazement.
Big Brother grows bigger
Life, James Hein, Published on 08/06/2022
» For some time now I have been having problems with USB and my hard drive letters. Over the course of a day or three, with the exception of C:, hard drives letters would vanish. I have C, W, X and Y. C is an SSD on the motherboard with the other three normal hard drives at 10, 10 and 8 TB. The other problem I had was the computer locking up as the system was scanning for a missing USB drive, even if I ejected them using the correct process. The exception was any Samsung phone that I tried to eject without success.
Always check your sources

» At the dawning of the internet age the aim was to provide a platform to share information, initially between higher education facilities. It was a golden age of what was essentially a library of information shared across the United States and later the world. The early fact checkers were academics interested in facts, data and a robust discussion.
