Some good questions and solutions have been seen in the simulation questions recently.   Higher thinking: Nuclear Power Plant Problems A nuclear power plant has n pitfall containing nuclear material, which are arranged in a straight line. If a

I. Overview I have written two articles about Oracle Data Pump before: Oracle 10 gData Pump Expdp/Impdp Oracleexpdp/impdp example These two articles describe the use of data pumps. In actual use, we will also encounter a problem where some ORA-xx

Ios 32-bit and 16-bit MD5 EncryptionDuring IOS development, we usually adopt encryption methods to ensure data security. Common encryption methods include Base64 encryption and MD5 encryption. Base64 encryption is reversible. Currently, MD5

This book is devoted to the usage of SED and awk, which is very detailed and quite good. Chapter 4 basic operations 1. awk and SED 2. Difference between SED and Ed Sed is an implicit global command, while Ed only affects the current line. Note: It

Today, I decomcompiled a project, and the form of the property in it is changed to the original form, such as get_xxx (), set_xxx (VAL), and there are still many. It takes a lot of time to manually change it, therefore, I want to replace the regular

The type character is the only required format field; it appears after any optional format fields. The type character determines whether the associated argument is interpreted as a character, string, or number. The typesC,N,P, AndS, And the

For beginners, the compilation of many commands is too complex, often learning for a long time can not write a beautiful program, so as to hinder our interest in learning compilation, many people give up. Therefore, I personally read the legal

  (1) It is impossible to fully remember so many algorithms.Common algorithms can be written after they are obtained.Not commonly used. Pick up the book and read it for 10 minutes to understand the algorithm (because it was previously recorded ).It

This article describes the principles and background of PGP implementation. For more information about PGP installation and use, see other documents provided in this document. PGP pretty good privacy is a mail encryption software based on the RSA

Certificates are generally X.509 certificates, which are then encoded by Der. Der is TLV encoded and stored by base64.   When we open ca. CRT, we will find that it is a base64 encoding. If base64 decoding is directly performed online, the decoded

Sys_guid () is a function provided after Oracle 8i. Sys_guid is generated and returns a globally unique identifier (original value) consisting of 16 bytes. On most platforms, the generated identifier consists of the host identifier, the process or

Therefore, I personally read the legal compilation, but I don't have to write a program. Writing a program is really not a compilation strength. You may wish to play DEBUG, sometimes CRACK has a more sense of accomplishment than a program (just like
