    WPS experation date

    New does not automatically mean better. Imagine that today (2025) a customer orders a replacement for a part that you originally made in 2004. You need to make an active evaluation of the changes in the standards over those 21 years and decide if they affect your part in your application.

    Part numbering conventions - what's the best practice in aerospace?

    What is the ten worst advise AI has given to an engineering question

    Last night, while I was watching a show called "Dan Snow revolution" on Japanese TV I put "Dan Snow revolution Japan tv" into Google. The AI overview was "there's no Japanese TV show with that name."

    Procrastinating on difficult work

    2400V startup of long idle motors
