That's a pretty serious box cutter.

Vacuum tubes don't die, they just slowly 'de-vacuum'!

Sometimes it's too fast...

Kiedyś dawno, wyczytane przeze mnie, że lampa próżniowa jest przodkiem tranzystora. Ale jaka to precyzja była potrzebna, żeby takowe stworzyć ! Nie to, co teraz, że na sztukę. I elementy, kondziorno itp ma " zadowalającą " żywotność 2 lata i produkcja masowa i hurtowa.

I agree for some reason I also prefer paper for data rather than looking at a PDF. I don't understand why ? the PDF is compact and tons of stuff can be in one place. Looking at a screen versus holding the paper or book just isn't the same . 👍

Also wondering about that; I think it's a few features that make paper books distinct. I'm saying this mainly from my perspective and experience. 1. Quick-ish access: You quickly open a book close to where you need and then turn a few pages rather than scrolling which can be frustrating. In case you're not familiar with the book, there's (almost) always a table of contents somewhere. 2. Very quick forward and backward jumping in case you need to check another chapter. 3. Optimal field of view, seeing both pages with no area lost to the user interface. 4. Detail zooming (if you have to use a magnifying glass) instead of full view zooming. 5. Multi-sensory experience which may enhance learning, as well as tuning out some distractors like notifications, web browser ready to check something, etc.
