    I was reading the article and got SAP/ABAP flashbacks. - source code in database: yes - own IDE for questionable reasons: you bet! - custom table objects: we got your back. - stran…

    His letter is from 1986. Mercedes W123 and R107 clusters had triangles pointing in the filler direction in the 1970s already. (Granted, not quite as clear as his next iteration).

    For DIY EV conversions (I built some cars) you usually hook up the "regenerate braking" to the brakelight switch. So as soon as you tap the brake pedal just a little, you start reg…

    Of course. It is an intriguing idea, but a local maximum. - The panel sits at open-circuit voltage of 48V - That then needs to be converted/boosted to 400V (conversion loss) - The …

    I built my own electric cars and calculated if this would be worth it. Roof of car is curved and you get the conversion losses (needs to be bumped to 400V to charge batteries). You…

    Excellent! I lived on a boat like this for many years and never knew about the risk of sudden tsunamis. I like that you can go under the trees.

    I finished the Spanish course many years ago (is finishing still possible?) Thanks for reminding me it had page translations, I did a few of those and enjoyed it! Shame it went.

    I build my own electric cars and a family friend asked me: Do electric cars still need a gearbox? The question is excellent, because many people think you can just skip the transmi…

    If's to the top as guard statements. Add asserts to the end of the function too. Loop's can live in the middle, take as much I/O and compute out of the loop as you can :)

    Oh of course the investor buys $75 of debt for $73, I get it now. I somehow had it in my head the other way around that he can borrow $75 for $73 which wouldn't make sense. Thank y…

    I didn't understand this section, why would they pay $73 for $75 and where do the $25 come from? "Investor Economics: Assume a $100 BNPL loan. $25 is paid upfront by the Consumer, …
