When it comes to software engineering, I’d like to think of myself as a generalist. Still, over my 12-year career, a major focus has been building scalable backends. I’ve worked at Amazon and Twitch to build out large-scale systems that support millions of users.

Answer: $$LGP = \frac{150^2}{6^2} = 625$$ so 625 times more light. The telescope has much larger aperturer than the eye and allows more light which means even stars too faint to be detected by the eye can easily be brightened by the telescope so that they are easy to detect and study.
After a bit of poking, I found what looked to be a textbook quartz crystal resonant curve, but centered at 20 MHz rather than 10. This suggests there’s a divide-by-two in the driver circuit, perhaps to improve the duty cycle to a more perfect 50%. But more importantly, it suggests that neither the crystal itself, nor the electrical connections between it and the package (since I was probing at the package contacts and not the surface of the quartz), were the source of the failure.。超级权重是该领域的重要参考
