I have not studied electronics but I have studied the Google IT support course among others so I have some basics of how computers and tech work. This type of documentary series is interesting because it brings history to life, and explains how things work. It is not sensationalist, does not use too much music and more. It just guides you through how technology works.

I was surprised to hear that transmission was as low as 2 watts and as high as just 11 watts. I also learned that for some communications they used just two watts of power for Apollo 13, 57 hours into the mission, to reduce power consumption. Of course on Earth they had a 270ft antenna to receive the signal. Compare this to a radio station that may use 50,000 watts. I don’t remember how many watts were used in satellite broadcasting but from a quick skim it’s about 20 watts but this goes to smaller and smaller dishes on earth. Starlink uses about 2 watts of power.

Today someone on twitter asked this question, and rather than be reply: 320 of 10,000, I chose to write a blog post about it. The TLDR answer is Vanilla JS because if you learn how it works without the help of a framework you understand the language. This doesn’t mean that I don’t have an interest in learning to take full advantage of frameworks.

As I listen to JavaScript Jabber one thing is clear. Whereas if we listen to courses and twitter discussions we are tricked into thinking that we should either use React or Angular we see, through JavaScript Jabber that frameworks are as diverse as they are flexible. One app will be excellent for one type of task and another will be awesome for something else. If you spend time learning Vanilla JavaScript, and then you learn about the diverse choice of frameworks then you can either write concise and effective code that does what you need with little to no bloat.

I am currently learning about Working With Service Workers. Service workers allow you to make a website faster, for those who visit a website more often, or offline, in situations where connectivity may be unreliable. Some of the code used can be found on my github page. MDN Web Docs also have useful information about working with service workers.

With service workers you can web first, retrieve from cache and stale while refresh:

When I wore Casio digital watches, Suunto Dive computers, Suunto GPS watches and other wrist wathces I was happy. You wore it and it tracked what you wanted it to track, from walks, to dives, to altitude changes, weather and more. With the Apple watch a new age emerged. The age of the Digital Watch as object of addiction. I don’t like the term addiction, but I use it for simplicity.

Recently I have noticed individuals tweeting as if they were people, asking questions and getting 120 or more comments. They ask a question like “What was your first OS” or “What is your current setup” or other questions. These are generic questions that everyone has an answer to, so everyone answers to them. Those answering think either that they will get a personal answer back, or that they will increase their visibility by answering to these questions where no one cares about the answer, except marketers.

Before the pandemic I liked to track sports, whether walking, indoor climbing, cycling, walking or more. I have tracked sports activities for two to three years at this point. I think I have almost 3000 tracked activities. That’s tracking my walks and more almost every day for at least ten years.

Recently the English, Swiss, Danish and other governments decided that they would declare the pandemic over, with no concern about the reality on the ground, or the warnings by the WHO not to assume that the pandemic is over. I also keep reading about how serious long Covid is, so despite the billions spent on propaganda to tell us that the pandemic is over, I am not convinced.

I like archeological twitter because it shows us curiousities every day of the week, several times a day. I like the image of the mosaic below because you see that it was quite deep, and hidden. Imagine digging down and coming across such a sight and site.

Today I went for my first flight with the DJI Mini SE and it feels very familiar, after flying a spark so frequently, until I crashed that drone. I would have replaced the spark but I didn’t because it would either cost two thirds to replace the old one, or cost a lot to buy a new drone, with batteries and the rest of the gear. I waited. I didn’t wait for four weeks, four months, or four seasons. I waited for two years, until I saw the DJI Mini SE was about to come out.

A few years ago we read about a vineyard where people had been digging. They discovered a vineyard that was well preserved. At least with a vineyard above there is no chance of a plow or other tool damaging the mosaic.
