The staff scheduler I built for that Fiverr client did exactly one job. It knew about his clients, his courses, his equipment, his week. It was a good staff scheduling model for precisely one business on Earth. Every sheet name, every constraint, every assumption was his. When I put it online I knew the truth: nobody else could use it without hiring me to rebuild it. So I rebuilt it once, properly, for everyone. This is how the generalization went.
Si alguna vez intentaste armar una ruta de reparto en Google Maps, ya conoces el problema: al llegar a la parada número diez, el botón de “Agregar destino” desaparece. Necesitas hacer 25 entregas y Google te deja planear 10. Llevo más de veinte años construyendo modelos de optimización de rutas para empresas, y en este artículo te muestro cómo hacer una ruta con más de 10 paradas en Google Maps — gratis, sin instalar nada y sin pagar una suscripción.

After I put the Roth conversion tool online, the question I kept getting wasn’t about conversions at all. It was simpler and scarier: “OK, but how much can I actually spend?” Almost every withdrawal rate calculator answers that by multiplying your savings by 4% and calling it a day. So I added a mode to my own optimizer that throws the flat percentage out and solves for the real number — the most you can spend every year while drawing every account down to zero by the end of the plan.
Continue reading “A Withdrawal Rate Calculator That Draws Down to Zero”This is the last post in my series on rebuilding my daily fantasy lineup optimizer (it all starts here). The math was the easy part. This post is about the day I lost to a bug that didn’t exist on my computer and only showed up once the tool was on a real server — the kind of problem that makes you question your sanity before you find it.
