marble buffer

This semester I learned an introduction to computer security from the Computer Science Institute, which is an entry-level course, but I still have a lot of insights and learned about buffer overflow attacks, one thing that suddenly occurred to me for a long time is to sum up and learn about the issue of the C language buffer. After such a long time, it was a bit embarrassing. This blog post should be an ent

The file_get_contents () function reads the entire file into a string. Like file (), the difference is that file_get_contents () reads the file into a string. The file_get_contents () function is the preferred method for reading the file content into a string. If supported by the operating system, the memory ing technology will be used to enhance the performance. SyntaxFile_get_contents (path, include_path, context, start, max_length)*/ Ob_start (); // open the

Implement a dual-Buffer Queue and a dual-Buffer Queue In the producer-consumer mode, we often use a queue, which has mutex and competitive operations when multiple threads share access, meaning that each access is locked. How can we better reduce the number of lock competitions? The dual-Buffer Queue to be introduced today is a good choice. The dual-

Vulnerability Report AnalysisLearn to crack friends must have heard w32dasm this reverse analysis tool. It is a static disassembly tool that, before Ida Pro is popular, is one of the tools that the cracking community must learn to use, and it is also likened to the "dragon Slayer" of the Cracked world.But even the "artifact" of such a cracked world is a buffer overflow loophole. It can be seen that it is in the process of cracking countless programs a

Compare the buffer query and no buffer query of MySQL in PHP, phpmysql About cache query and unbuffered QueryThe MySQL client has two types of queries:Buffer query:The query results will be received and stored in the client cache, And the next request to obtain Row Records will only be obtained locally.(1) Advantage: You can freely move the "current row" pointer in the result set, which is easy to find beca

buffer Overflow Analysis is a collection of lecture notes for the video course of the same name that I recorded for "I Spring" (www.ichunqiu.com). Every time I finish writing my course documents, I will explain the course according to the contents of the document. And the content of this series is from scratch, to give you a more easy-to-digest buffer Overflow vulnerability explanation. The whole course is

The page. Buffer attribute in ASP. NET is used to buffer page execution results. It is generally set in the @ page command. The default value is true. This attribute is applicable to web optimization.ProgramThe performance is useful, as described below: Set buffer to false: The page is not buffered, And the execution results are successively sent to the browser

In PHP programming, we often encounter some functions that directly generate output, such as passthru (), readfile (), and var_dump. but sometimes we want to export the output of these functions to a file, or process and output them first, or use the output of these functions as a PHP programming, we often encounter some functions that directly generate output, such as passthru (), readfile (), and var_dump. however, sometimes we want to export the output of these functions to a file, or process

About buffered queries and no buffer queriesThere are two types of queries for MySQL clients:buffered queries: will receive the results of the query and store them in the client's cache, and the request to obtain row records is only obtained locally.(1) Advantage: You can move the "current row" pointer freely in the result set, which is easy to find because the result is in the presence of the client.(2) Disadvantage: Additional memory is required to

This join is actually called a full join. Virtually every table participating in a join requires a join buffer. So when the join appears, it'

Brief introduction Another very good feature of SQL Server 2014 is that SSD can be virtualized as part of memory for use by SQL Server data page buffers. By using SSD to extend Buffer-pool, a large number of random IOPS can be hosted by SSD, which reduces the random IOPS and page-out for data pages. SSD as Buffer Pool SSD is a solid-state drive, unlike a traditional disk with a magnetic head moving part,

Introduction to VC double buffer Drawing Technology and vc buffer drawing Double-buffered plotting is a basic graphic image plotting technology. First, it creates an object in the memory that is consistent with the screen drawing area, and then draws the image to this object in the memory, finally, copy and display the graphic data on this object to the screen at a time. This technology can greatly incr
