Hiya, https://jumpstartsignal.com/how-it-works/ outlines the methodology + more additional interesting info in https://jumpstartsignal.com/changelog/ and https://jumpstartsignal.co…

Added a changelog as per my previous comment/response https://jumpstartsignal.com/changelog/ Thanks for the feedback, makes sense!

Overfitting on historical data is a real risk and defo a concern (there's been lots of learnings lately). The backtest wasn't naive. Fundamentals used filing dates not period-end d…

So, you kind of hit the nail on the head with "if" and "purpose". So, this is not an ESG fund (per your link) and more about baked-in filtering/excluding certain parts of the inves…

Hey HN, JSS(JumpstartSignal) is a free, ESG-filtered daily stock screener. I built it after some really badly-timed quantum computing stock buys, so I felt I needed to learn more a…

I'm the author and am happy for any feedback + to answer any questions about this deep dive. It was fun to write about and learn more as I continue my 802.11 journey + building too…

This is great feedback thanks and a very interesting point. Most laptops these days are constantly chatting towards the Internet, just have a look at wireshark! But, the local LAN …

Surprised no one has linked to this yet https://www.levels.fyi/?compare=Google,Facebook,Microsoft&tr... where you can view the salary grades of the FAANG's compared to other public…

Zen, ego, statecraft, belief systems and barriers of entry. Perhaps read 'The Relation of Science and Religion', Richard P. Feynman. I have chewed this cud before: http://tr.im/f95…
