👏 Some nonsense don’t want to see can directly skip

The importance of the site and the setting

Shooting 🏹 needs to go to the range to learn, skiing 🏂 needs to go to the snow resort to experience, driving 🚗 needs to be able to practice on the road, and programming development can not only complete the functional process of the product, but also need to ensure the reliable performance of the system. As you can hear some of the system monitoring metrics; QPS, TPS, TP99, TP999, availability, response time, etc., and the sum of these indicators is the health of a system. But if you’ve barely heard the technical terms and haven’t been exposed to such scenarios, it’s a lot like getting 100 points on subject 1 of a driving license, but not on the road. Without such technical scenarios to train you to continuously experience the temperament of the system, no matter how many ideas you have, you won’t be able to achieve it. So, if you really want to learn, you have to go to a real scene, try the water to learn to doggy paddle.

How big your blind spots are

The same book, the same road, the same city, do you really think that life has a choice (no ~ life’s choices are not so many twists and turns)? Sometimes a lot of options are just a chore, and given multiple chances you’ll always choose the same thing. It’s not whether you choose or not it’s your cognitive range that determines what you do in the next second, and the next second determines the next second and the next second. Just like a glimpse of the leopard, 20% of the area in your vision is black, or even ignore to see, and this can not see 20% is the luck of life! However, people can learn, can grow, can be transformed, can work hard, through a metamorphosis to see the remaining 20%!

Just like the people who love the locomotive: holding the throttle torch, this life is not a locomotive life! — You can, too, live up to the life of an ape with a keyboard torch in your hand, just kidding. Let’s get to the point
