41·8 天前It’s all Marketing. In order to attract users with fancy looking interfaces, many usability rules get overriden.
This started already years ago with the new, sleak looking Windows 10. Internally the usability problems were known. But marketing pushed for the release date. This UX drama was costly. over 5 billion in the air for the launch alone. Ending in a blame.
Even though it’s common to bully on Microsoft, it’s not true in this case. There have been many studies and user tests to find an understandable way for users to reach that massive functionality of the MS office software. The Ribbon interface was the best in those testings.
That sort of competitions exists already for ages. RoboCup is the keyword to search Youtube. Besides other shapes, the Humaoid league is this area.
Proud to say, that Germany is quite advanced in this competition. I once talked with a Prof of the winning team about the challenges. It‘s mainly speed of computing and recognition, coordination with team with close to no network connectivity (think about how crowded networks are at every standard exhibition)
2·16 天前Okay I see. Actually the COMPATIBLE refers to the blood group not to people.
This is actually word picking. However, there‘s a little difference.
She has this special blood group. And there is only one person known who is compatible. If there is another person the only is away.
If she is only compatible with herself, the only would stay, if there‘s another person with this special blood group.
So, the original writing is the correct way.
2·16 天前Even though it’s been thought to us in school, humankind never used money / coins in its history. It was always rather a kind of obligations and credits.
Only at the time of the ancient empires (romans, han dynasty) coins were used strongly. But mainly for paying the army soldiers. In middle age that coin thing faded again.
Can you source your statement that fast charging reduces lifetime?
I‘m not sure if fast charging degrades batteries. Just read somewhere an article stating that fast charging initially - first charge - boosts the overall capacity of the batterie due to chemical reactions that do not occur that long at anodes.
The issue with fast charging was the thermal management - it’s getting to hot. This is managed by good battery management and a different packaging of cells nowadays. I think fast charging isn’t an issue anymore. Can’t provide you a link or such, it’s what I gathered through serveral podcasts.
In recent test of a German auto club they found out that it‘s cheaper/ more effective to charger faster. You loose a lot of energy if you load slow over hours.
This energy is taken by the electricity of the car. So, while charging the car is on and takes some Watts. There are just a few brands that have decoupled the charger circuit from the overall electric circuit of the car.
Can’t find the article now, but I think charging a PHEV through a standard power plug had about 20% energy lost. It was clearly visible that a charger is a good choice.
You‘ll loose
- ~10-30% AC 2.3kw Standard Power Plug
- ~ 5-10% DC 11kw Wallbox
- Internal car electronics are crucial: Is the loading circuit de-coupled or the entire car On?
- Temperature or pre-heating the battery before loading reduces losses at DC charging
My first typing was a game into C64 using machine code. Game magazines at that time dedicated a few pages with lines of hex numbers for games. After typing 4 pages you had a game.
Unfortunately, I‘ve got my data tape recorder two month later for xmas. And mom was nervous about keeping the power on for days. I entered those numbers quite some times. Load„*“,8,1
Still I doubt those „rights“ are exercised.
This map isn’t worth a discussion. I seriously doubt that countries such as Sudan, Bangladesh, and Cambodia have a paid paternity leave. If so, it isn’t worth the paper it’s written upon. In those countries the government shit on worker rights.
Good point.
However, there‘s a crucial difference to cars. Robots are hardware AND software. And I don’t know anybody who uses Windows 95, CorelDraw, and Netscape today. Software and connected hardware outdate mich faster than simple hardware.
The battery! It lasts for just 1-3 hours. That’s why there aren‘t robots on the battlefield nowadays. Once the energy issue is solved this will change
Sure. But at what costs? One can do many things by technology. Are people willing to pay for it? And how much?
Actually, this is where mastership comes from.
If you spend even more time, you‘ll become a master in this matter. Because you recognise the little differences to the former experiences. And you learn to handle and to steer it.
It‘s not all bad in not having a first experince only.
