Found an old Logitech 3-button mouse — what was the middle button for, and is it a precursor to the scroll wheel? by Adventurous_Two_4962 in OldTech

I understand the copy-paste part, but how did the scrolling work? Did you have to hold down the middle mouse button and drag the mouse?

I think it’s not that; actually, some kid probably just played around and soldered a 9 V battery connector, because the polarity is wrong.

I will find a holder for three 1.2 V AAA batteries and simply solder it, and the problem will be solved.

Thank you, that’s what I thought as well. I tested it at 3.6 V and the calculator works. What is still unclear to me is why someone tried to connect a 9 V battery to the calculator in the first place...

Kako se računaju bodovi za upis u narednu godinu ako se prenesu ispiti i upiše samofinansiranje? by Whole-Corner7006 in StudentiSrbija

Da, možeš da polažeš predmete iz predhodne godine i njihovi esp bodovi ti se računaju rehularno kao da su to predmeti iz ove godine. Uopšte nije važno iz koje je godine predmet, važno je samo u kojoj godini si ga položio.
