Article link to title Technical link to title Database Architects: The Great CPU Stagnation
The rapid growth of [[CPU]] performance has disappeared. The author compared Cores/$, (Cores*GHz * IPC)/$ and B transistors/$ to verify that the development speed has been slow in the past 5 years.
Personal network disk experience Do you really have so many things to store? I feel that what I need daily is more for backup scenarios, and I don’t need a NAS that can read and write at any time.

Uptime Guarantees — A Pragmatic Perspective
What level of [[SLA]] should one aspire to? In theory, the higher the better, but in fact, considering the cost, it may be the best for the product. You need to evaluate the direct loss caused by the downtime to determine the time you can tolerate. 99.99% vs. 99.5% requires effort , The cost is much more. Sometimes failures may not be related to technical implementation, but may be related to operations.
Practical example: The number of failures in Github Action Q1 has reached 55, but it does not affect everyone’s continuous use of it. It may cause complaints, but the actual loss caused may not be accurately evaluated.
