  • Many people think of industrial developments in slightly different terms. Industry 4.0 is a fairly modern way to look at it.

    “The First Industrial Revolution was marked by a transition from hand production methods to machines through the use of steam power and water power. “

    “The Second Industrial Revolution, also known as the Technological Revolution, is the period between 1871 and 1914 that resulted from installations of extensive railroad and telegraph networks, which allowed for faster transfer of people and ideas, as well as electricity.”

    “The Third Industrial Revolution, also known as the Digital Revolution, began in the late 20th century. It is characterized by the shift to an economy centered on information technology, marked by the advent of personal computers, the Internet, and the widespread digitalization of communication and industrial processes.”

    Burning coal was common in stage 1, oil gradually became more common in stage 2, nuclear in stage 3 etc. In this system, the power source wasn’t really the defining feature, but what you could do with it was.










  • The packaging also offers some hints. It has a glass jar and a metal lid, which might click when you open it. My guess is, that bottle went through an oven before being shipped. Glass is heavy and expensive, which isn’t what the manufacturer wants. They wouldn’t use a package like this unless they really have to, which implies heat treatment.

    If sterilized properly, that process killed all the microbes in it, which means you can safely ship it and store it in ambient temperatures for a very long time. Chemical reactions still take place, which might affect the taste if you store it for decades or centuries. However, if it’s properly sterilized, microbes aren’t involved in any of it. Once the lid is opened for the first time, airborne microbes immediately contaminate the contents and the clock starts ticking.

    Salt and vinegar make the environment hostile for most microbes, but not all. This method will clearly help with limiting the growth rate, but keeping the jar in the fridge would be my advice as well. This way, you get the benefits of multiple methods of slowing down the growth rate.


  • Yes and no. GPT usually gives me clever solutions I wouldn’t have thought of. Very often GPT also screws up, and I need to fine tune variable names, function parameters and such.

    I think the best thing about GPTis that it knows the documentation of every function, so I can ask technical questions. For example, can this function really handle dataframes, or will it internally convert the variable into a matrix and then spit out a dataframe as if nothing happened? Such conversions tend to screw up the data, which explains some strange errors I bump into. You could read all of the documentation to find out, or you could just ask GPT about it. Alternatively, you could show how badly the data got screwed up after a particular function, and GPT would tell that it’s because this function uses matrices internally, even though it looks like it works with dataframes.

    I think of GPT as an assistant painter some famous artists had. The artist tells the assistant to paint the boring trees in the background and the rough shape of the main subject. Once that’s done, the artist can work on the fine details, sign the painting, send it to the local king and charge a thousand gold coins.





  • It depends on the kind of risks you have in mind.

    Are you worried about someone hacking an account, stealing passwords and committing identity theft? If so, the stakes are pretty high, but the probability is low as long as your brother takes care of updates and passwords. Also, avoiding shady software and sites helps too. I prefer to call this category security, but it certainly has privacy aspects too. IMO online security should be a high priority.

    However, if you’re mainly concerned about Amazon, Meta, Microsoft, Google and other companies collecting data about you, the situation is very different. I call this thing privacy, and the risks are smaller, but the probability is very high.

    When it comes to security, you just need to show what has happened to other people who screwed up and made themselves an easy target. However, privacy is a bit trickier. Appreciation of privacy is a more philosophical matter, since the practical side of it isn’t as tangible. If your brother doesn’t have certain values, principles or philosophy, it’s going to be difficult to convince him that privacy matters.

    If your brother already takes good care of online security, but ignores privacy, you could talk about the way companies use your data. Focus on the ethical side of these practices. If not, forget about privacy and focus on security instead, since that should always be the higher priority.
