Analysis of anti-heuristic code simulation detection technology (3) bitsCN.com can cheat AVP, Dr. web, f-prot v3.04 (even with the/PARANOID flag), but not through f-prot v2.27, Nod, Ikarus and Dr. solomon's. f-prot v2.27 and Ikarus detection. On the other hand, we can also cheat "normal" using PIQ means (of course you should remember that this does not run on the current processor ). 2. FPU: I like the meth

Oracle redo complexity-oracle Core Technology Reading Note 3, redo-oracle I. Overview We know that in oracle, Every modification to a piece of data generates a redo (that is, redo, which records the modified content ). The purpose is to back up the modified data for future redo. Now there is a problem. Redo logs are generated when data is modified in oracle. These redo logs are stored in a redo log buffer.

Linux power Management (3) _generic pm reboot process 1. ObjectiveIn the process of using a computer, shutting down and restarting is the first two operations learned. Similarly, these two operations exist in Linux, called Shutdown and restart. This is the object to be described in this article.In the Linux kernel, the mainstream shutdown and restart are implemented by "reboot" system calls (specifically re

Send messages When the socket is open (that is, after the onopen listener is called and before the onclose listener is called), you can use the send method to send messages.

when returning an external row. You should select only the outer row to take a value of NULL, and a column with a value that is not NULL in the other rows. There are three scenarios in which you can consider safe use: primary key columns, join columns, and columns defined as NOT NULL . The column value of the primary key cannot be null, so if NULL appears on such a column, it means that the behavior is an outer row. If a row's join is listed as a null value, the row is filtered out in the secon

scenes using the temporary effect of vision; because each frame requires 798x798 pixels, the amount of data required per second is as high as 2409x798 ^ 2x3) /1024 ^ 3 = 4.286 GB!

fact, the computer world, including hardware, network, software is to introduce new layers, objects, services, so divide and conquer to simplify the problem of solving, and the real world is not so. Of course, divide and conquer, split solves some problems, but introduces another complex/interactive problem.
