I tried to transfer my eSIM from my old S21 to my new S24 the other day. It failed miserably. My carrier charges me $10 for a new eSIM (which i think is way too much for a digital service). Transferring eSIMs sounds like a good idea if it works, but might not be endorsed by carriers that earn large profits from the service.
I'm not American, but I've lived a few years in the US. I find it very interesting that the US invented the electric infrastructure that we use today, but they really screwed up a few things. Firstly, the connectors are far too unsafe. They are flimsy and have no protection from electrocution. Secondly, by using 120V as the main voltage, you need more current to do the same amount of work as a 240V system. Thay means thicker wires, more stress on the plugs, and greater fire hazards.
I bought an Aeropress a few years ago and absolutely love it. Then I realised that my cheap grinder wasn't all that great, so I bougt a $400 grinder. My quality of life is at its peak right now.
Even if this might sound crazy to some, it doesn't sure me at all. Industries are not upgrading systems just for fun. It's only done when it is absolutely necessary.
I've worked with systems running in windows 95. On laptops so old they didn't have USB. The only way to transfer new files to it was to use serial link (we didn't have floppy drives). What did that ancient computer do? Communicate with subsea control systems for oil wells.
The problem isn't the LED itself. The problem is engineers that read the datasheets where it shows which forward current they need. What they forget to think about is that the recommended forward current is for max brightness, so they slap whichever resistor they need, and never give it another thought.
Whenever I design a LED circuit that is only used as an indicator, I always make it 10% or less than recommended, because I do not need to burn away my retina when I test the boards.
I agree. Because of this, I actually changed carrier to one that was cheaper, had better coverage and free eSIM.
