ludoro··on Ask HN: What Are You Working On? (June 2025)
Machine learning at scale: a substack newsletter about machine learning system design for large scale systems :)
ludoro··on Costs of running a macOS app studio business
I will bite. L4 Google in Zürich, Switzerland. Base: 163k CHF (very low, just promoted), 15% bonus, 50k USD GOOG / year. Not counting stocks, I net 9k a month while maxing retirement account (aka Roth IRA but with less returns) at 2.7k CHF / month. Rent: 2.3k / month in city center, Health insurance: 350 CHF / month. No other significant expenses.

I invest 3.8k CHF / month from base only. All in all, I save ~100k CHF a year counting bonus and stocks.

ludoro··on Show HN: PySaaS – Python SaaS starter kit
As a ML engineer / back end type of dev, I really like the idea that I can build everything in Python. Really tempted to buy it but I am a bit scared about support.

Can you share what's the plan? I buy it now, do I get updates? What happens if you stop working on it? How do I make sure the code is of "high-quality" and not glued together?
