This is a 1972 documentary about the life in the year 2000. It is in German, but English subtitles can be set up in the video settings. It turned out to be a bit different, but some predictions back then came to reality.

Simplified:

Having a fridge running is nothing complicated compared to a computer. The compressor and the light inside are the only things that are being powered. Both components work mechanically: The compressor has an electric motor that is running when fed with electricity. Pistons inside the compressor are linked mechanically to the electric motor. The light inside the fridge is operated with a switch that is mecahanically connected to the door. The light is off when the door is closed. As long as electricity is fed to the fridge, it keeps running.

Computers however are more complicated, as they basically are running clocks that connect an event with a time stamp. They can get disturbed easily when several events happen. When a computer is running long enough it can happen that the memory overflows when a specific event is being executed for example. For this reason it is renommended that your smartphone is supposed to be restarted at least one a month, otherwise it couldn’t function properly.

If refrigerators were operated the same way as a computer, like your laptop or smartphone, I bet it has to be restarted every once in a while, otherwise a malfunction would occur. To my knowledge refrigerators are built the same like 40 years ago, albeit with more efficient compressors, better insulation and less harmful refrigerant.

Really? My laptop doesn’t. Maybe it depends on if the battery is designed to be removed by customer or if it is hidden inside the laptop, making it accessible only with tools.

Since laptops are equipped with a battery anyway, they lack of a coin cell (mostly a CR2032 cell) to keep track of time. This means that your laptop will not be able to estimate the correct time and date when powered with energy outside of the original battery, and these settings have to be made manually each time your laptop will be used.

It will work fine without the correct time set, but you might have issues with files that are created “in the future” (from your laptops perspective).

I have an old laptop (still in use occasionally, because I have a scanner that is too old to be operated with current software) where I replaced its battery once. The sign the battery was dead was that the OS issued a warning the laptop was not able to tell the correct time.

Not that I know of. I think they automatically use the mask that works “best” while these codes are generated. I have tried some (free) QR code generators and there is no hint that the mask can be choosed.

If you have Affinity Designer 2, you are able to generate QR codes within the software. No need to sign up for a free one. But when creating a QR code with Affinity, there is no option to choose the mask.

that is cool.

With progressing age one has to look up urban dictionary more and more often.

Well, reading all the answers makes me realize that there might have been a kind of evolution when it comes to TV remotes. I just didn’t come across back lit remotes when I saw them with people in my social circle. Maybe my people just don’t have the latest TV set.

Neat.

The thing that bothers me whenever I see a TV remote is that there doesn’t seem to be a remote control with illuminated keys, like on a computer keyboard. That way you can see the buttons even under dim lit conditions. Also, why aren’t there any remotes with a built-in battery that could be charged like a smartphone?

I don’t own a TV, but I know that back in the days of bulky CRT TV’s there were some remotes that could be iluminated. White LEDs weren’t a thing back then, so they used incandescent lamps which drained the 9V battery fast.

Why aren’t back llit and rechargeable TV remotes a thing today, especially because white LED’s and batteries are quite efficient today?

Probably safer than eating tide pods.

Sadly, in this world you accomplish nothing for being nice and considerate. If you want to leave an impact (anything - a new invention, a new product, a new idea, anything with impact to contemporary culture) you have to bully yourself to the top, including stealing ideas and screwing people over, as well as to exploit people. All “great” people who accomplished something did that: Gates (Microsoft), Jobs (Apple), Musk (Tesla, Twitter), Bezos (Amazon), Thiel (PayPal, Palantir), Zuckerberg (Meta), Huffman (Reddit), as well as many politicans. It’s a personality treat.

Here is a video that explains the issue, albeit it focuses on designers:

Are you saying all laws are futile? Otherwise what is different with this law that makes it futile?

I do not say that all laws are futile. The difference with this particular measurement is that it is odd to me, that a no-weapon zone is being established, as it is quite unusual that Germans carry around weapons in general. At least not where I live. People carrying around weapons of any kind is just not a thing here.

There are other laws, speed restrictions for instance. I get that there is a necessity to enforce such thing, as people have cars and tend to drive faster than they should. Speeding with a car is more common than carrying a weapon. That’s why this law makes sense, as it adresses the issue right there. Speeding doesn’t have an underlying issue that causes drivers to speed.

The thing what makes it futile in my opinion is that a restriction in carrying weapons does not solve the underlying issues (the root causes of socio-economic inequality, among others) that probably lead to harming others with knives. It’s just treating the symptoms, not the root cause.

This would be the use case, where you would break the law, when entering such restriction zone. Unless, of course, your skin tone has the right shade, as police unfortunately does things like racial profiling. If pale, you were on your way to a cooking party - if darker-skinned, you luckily were caught in the act!

Fair enough, I didn’t think of that. What you described is the intended use for pocket knives, MacGyver style.

What I thought of when writing my comment were kind of hunting knives. No one needs that inside an urban environment.

The question is: why would anyone carry a knife in the first place? I can’t think of any reason. Personally, such law wouldn’t have any impact on me, because I don’t carry a knife with me. I can see the intention with such law, and it probably might help to percieve a more secure enviroment.

If someone wanted to do some stabbing inside a party district, such law wouldn’t stop them - unless one has to pass through a security checkpoint (which to my knowledge are not a thing).

This is a futile attempt to establish safety, and it is done so that it can be claimed that something has been done.

If some person has the intention to do any harm to others, this person would not be stopped by any restriction to carry any weapon.

The real issues lay much deeper: A growing number of refugees and asylum seekers that want to work, but are prohibited to do so, but at the same time these are competing in an already tight housing market. Raising costs of living, growing inequality, growing envy and a part of the population which is on the brink of shiftig into a nazi movement, with a growing resentment to foreign people. It takes more than putting up a sign that says that weapons are forbidden beyond this point to solve these problems.

Also, in Germany there is no reason ever to walk around with waepons. Compared to other parts of the world it is pretty safe here.

Putting up a sign that states that weapon are forbidden would have the same impact as putting up a sign that forbids wild fires in the forest or flooding near a body of water.

The video is about the perception of distinct sound patterns (frequencies). Some sounds which create accoustic illusions are made with a pipe organ. Also the video explains why we are able to focus on sounds like distinct conversations when there is background noise. Although the video doesn’t go into the deep, it is well-explained.

Yeah, that’s quite an unfortunate thumbnail.

Additional to that account thing: Why does one have to install an app in order to access all functions and to toggle options of a device?

My girlfriend once has bought new headphones. In order to switch off the telephone function (you can - among other things -answer calls from the connected smartphone by touching one side of the headphones) it is required to download an app (a sloppily programmed one as well) to switch off this specific function. All other functions (volume, play, back and forward) are operated with buttons.

I heard about the same thing but with printers: The scan settings can only be toggled by an app (I think it was HP who has that feature - who else!?)
