5、FreeBSD 上 ELF 文件的 magic number 就是文件的前四个字节依次为"7f 45 4c 46",对应的ascii字符串即 "^?ELF"。 6、tar 文件的 magic number 是从第257个字节起为 "ustar"。 7、PE文件中,在DOS-根之后是一个32位的签名以及魔数0x00004550 (IMAGE_NT_SIGNATURE)(意为“NT签名”,也就是PE签名;...

At this point, I might congratulate myself for making the code three times faster. However, the user won't notice it if 0.1 percent of the program becomes three times faster. Here's a third approach that I used to make my code run faster, back in the days of JDK 1.3. Instead of ...
JEP 458: Launch Multi-File Source-Code Programs:Enables developers to choose whether and when to configure a build tool by enhancing the Java application launcher to enable it to run a program supplied as multiple files of Java source code. ...

Capture groups are numbered, starting at 1, and moving from left to right, by counting the number of open parentheses it takes to reach them. The special group number 0 always refers to the entire expression match. For example, consider the following string: one ((two) (three (four))) ...
it will post-process the core dump to rename it with additional information and also add some additional details into the core dump. The J9 JVM is not able to do this post-processing if a pipe program processes the core dump first. However, disabling piping will disable piping for all proc...
