Many people think that computers have become so intelligent that they will no longer need programmers in the near future. Others think programmers are geniuses who can constantly solve complex math problems in front of computers. Even a lot of programmers have no clear idea of what they do. In this article, I want to explain to people who do not know what the programmer is doing.
Programmers are translators who translate human ideas into compu

What are the usage scenarios?A:Do_direct_ioIt is often used to transmit large volumes of data with high speed. Do_buffered_io is often used to transmit small pieces of slow data. Do_direct_io is more efficient (Only Memory Locking
data tables.In the relational database world, we must master table structures, table records, and other concepts. There is no object concept here. When we use relational databases in the OO language, since there are a large number of objects in the OO world, data must be converted and transmitted between the two different worlds.
This results in a large number of temporary junk objects and increases the complexity of the application system. This is
Lists and tuples, dictionaries1. List list:["Ele1", "Ele2", "Ele3", "ELE0"]A list is a set of arbitrary types of values that are combined in a certain order, accessed by offsets, variable lengths, heterogeneous, and arbitrarily nested, mutable sequences, arrays of object references2.

of the mask implementation is a drawcall to create a stencil mask (to do pixel culling), then draw all the child UI, and then remove the stencil mask in the last Drawcall. This two drawcall can not be compared with other UI operations to batch, so the surface to add a mask will be more than 2 drawcall, but, because the mask is similar to the "hamburger-like" rendering order, all mask child nodes and other UI is actually in two worlds, The hierarchica

It is important to note that since this function of the Casper contract is executed as part of the state transfer function, the execution process is completely clear as to what each chunk and state root node is, at least in its own world. Even from the outside world, the verifier of the No. 20125 block to propose and vote does not know whether the No. 20123 block will be finalized, but when the verifier has processed the block, they will know it-or they may be dealing with bot
Recently, this topic has been in the "newsgroups" (er, at least in a lot of blogs), I have been thinking about how to reply to everyone ... But in fact, I have no need to reply at all, because Dave Totzke has done it for me. He mentioned one point in the article: we should let C + + continue to exist, because Office is written in C + + ... I'm not too flattering about this, because the reason for this is actually that the managed world cannot replace our need to write local code for the underlyi
Author: devway (from xfocus bbs)As a reality, network security has three stages: emergence, development, and extinction. Of course, this is from the perspective of the philosophy that everything begins and ends. What we see at the lower layer of technology is code. What we see from the philosophical perspective is the weakness of human nature.In terms of the most basic principle, security is caused by the inconsistency between the physical level of the computer and the mental level of the person

In the previous section, we showed that users who have logged on can be found through the scanStates function. However, this function has many other purposes. Because scanStates is based on signatures, we can use it to detect the types and versions of different network devices. The signature is based on the error message caused by a script tag when a resource is remotely accessed, for example,

This is a major event in the Open Source Field of the virtual world.Press releases released by the two organizations claim the establishment of the world's best open-source platform and relevant standards. For the future virtual world architecture, realxtend puts forward some very meaningful solutions different from
virtualuniverse, which has a series of locale objects.
A Locale object that provides a reference point in the virtual world. The Locale object can be seen as a marker for defining the location of a visual object in the virtual world. A Java3D program has more than one virtualuniverse object, which is technically feasible. Therefore, multiple locale objects can be defined in the virtual world. However, there is no internal communication between multiple virtual
