Is it not rather useful in this particular case? You will see the reported capabilities whenever you plug in a cable. Or do people rather want to diagnose and label their cables just once?

Half of the comments are in this subthread which derailed the discussion on this submission before it even started. Here the damage is done but maybe, please, refrain from doing so elsewhere.

I’ve considered that before but never actually got one. For soldering SMD a small hotplate was a difference like day and night already. How cheap could I get away with when buying a hot air station/gun?

To remove SMD ICs more easily with a soldering iron, you can create a tool to help with it. Cut a lengthy piece with a curved end at the front (looks a bit like a finger) from an aluminum can and sand away the inner coating and print on the outside.

Then work the curved end between IC and PCB and start heating the contacts left and right while continuing to move the tool further in once the solder at a leg melts. The legs with solder on them will not attach to the aluminum and you have the IC off the board in no time.

For soldering the author might consider “drag soldering”, i.e. put a small blob of molten solder on the legs and keep moving the tip of the iron over the legs on one side. Keep doing that until there are no bridges left.

That should be the most common behavior. Barcode readers work the same. In the past, you even plugged barcode scanners between keyboard and PC and they injected the key codes of the detected code into that.

Very nice, thanks for sharing! Maybe show which upper or lower values are included in the intervals? A notation I am familiar with uses outward facing brackets if the value is not included in the interval. That always applies to infinity.

Applied to the cases here:

]-∞, -1] U [0.5, +∞[

The excluded interval in between becomes ]-1, 0.5[ then.

That’s how min (and analogously max) works, right? min(A, B) = [lo(A,B), lo (hi(A), hi(B))].

Edit: idea: copy a formula from the results section to the input field if the user clicks/taps on it.

Taking differences between degrees Celsius values is absolutely fine.

Ratios are undefined because the Celsius scale has no absolute zero while the Kelvin scale has.

We should have kept using nuclear? That nuclear of which refinement capacities are over 40% in Russians hands? For conversion it’s even a combined 63% for Russia+China.
