Show Notes
SOXL surged 2.59% to $168.53, leading a broad tech rally as the Nasdaq closed at a fresh all-time high with yields pulling back slightly. • VGT, QQQ, and VUG all posted gains of 0.68%–1.02%, with megacap and growth stocks advancing broadly on the session. • Reflection debuted Beam, a 501-billion-parameter open-weight model targeting enterprises and governments with fully local, customizable AI at lower compute cost than frontier rivals. • Interview Tip: Before architecting anything in a system-design interview, ask what the business optimizes for — precision, recall, or F1 — and nail down the hard latency budget first. • Did You Know: A loss function is how a machine-learning model measures how wrong it is — like a GPS recalculating your route every time you make a wrong turn.
