Recommendation 101: Use extension methods to "add" methods to existing typesConsider how to have a new behavior for a sealed type. We used to create a wrapper class and then add a method to it, which doesn't look elegant at all. We might consider modifying the design, modifying the sealed type directly, and then publishing a new version for it, but it relies on you having all the source code. More often, we will take the approach of programming to API

For example, you cannot open multiple scripts for editing at the same time. Object spy en

MySQL is a powerful open source database. With more and more database-driven applications, people have been pushing MySQL to its limits. Here are 101 tips for adjusting and optimizing MySQL installation. Some of the tricks are specific to the installation environment, but these ideas are generic. I've divided them into several categories to help you learn more about MySQL's tuning and optimization skills. MySQL server hardware and operating system tu

CBC byte flip attack-101 Approach 0x00 translator's preface Topic articles in drops: using CBC bit reverse attack to bypass encrypted session tokens The origin is a question produced by candy. I can see that the author of the original article elaborated on this question in more detail. Although it has been a long time, I can translate it to Zhu Jun to learn how to think about the problem.0x01 The essence of this attack method is:Change the plaintext
