1. The origins of AOP technology
The birth of AOP technology was not too late, and as early as 1990, researchers from Xerox Palo Alto research Lab (i.e. PARC) analyzed the limitations of object-oriented thinking. They have developed a new programming idea that may help developers improve productivity by reducing code-duplication modules. With the deepening of research, AOP has gradually developed into a complete set of program design ideas, various a

At the same time, in the process of working with top gurus such as Andrew Koenig (chairman of the former ISO C + + standardization Committee) and Bjarne Stroustrup (founder of the C + + language), Stepanov began to notice that C + + The potential advantages of language in the realization of its generic ideas. In the case of the pointer in C/s + +, it is flexible and e
like real life with the hands dragged, so Palo Alto Genius invented a mechanism, through which it replaces our hands to manipulate the screen things, this mechanism is the window, icon, menu and pointing device, English abbreviation is wimp.
This mechanism is promoted by Apple and MS in the world, one for decades, until now technology progress, and began to gradually get rid of agents, with direct manipulation of the alternative. This time without A

If an expression containing a two-dollar operator appears in the ternary operator "? : "The"? " , you should add a pair of parentheses to the expression. For example:

UI is presented to people, and it's used to interact with people, and it's not easy to use a machine to simulate a living person to automate a component, and the autonomic view seriously impairs the testability of the component.
To address these problems caused by autonomous views, we need to adopt a policy of separation of concerns (SoC, seperation of concerns) to separate visual interface rendering, UI processing logic, and business logic, and to minimize the impact between them using a reas

Malicious programs turn infected computers into Web proxies
Anonymous proxy is vital to protecting users' online privacy, but it is dangerous if a person's computer becomes a proxy server without consent. Researchers from the security company Palo Alto experts have discovered a new malicious program family ProxyBack that can turn infected computers into proxy servers. The computer infected with ProxyBack first establishes a connection with the proxy
, OpenVPN2.2.1, and OpenSSL1.0.1 on KVM virtual machines. But Str ömberg said he suspected that all OpenVPN versions that use the vulnerability have similar vulnerabilities.
For many small and medium-sized enterprises that adopt OpenVPN, the good news is that the OpenVPN service that enables TLS Transport Layer Security Authentication will not be affected, because TLS authentication uses a separate private key to authenticate TLS packets. (Editor's note: security issues of SSL/TLS should also be
vertices and bars in different sequences to represent letters and numbers. Modern data networks use 1 and 0 to achieve the same results. The biggest difference is that in the 19th century, the reporter may only transmit four or five verbs per second, and today's computer communication speed can reach 1 Gigabit, in other words, that is, the data can be transmitted for 1 and 0 for 1,000,000,000 times each second.
Although telegraph and telex typewriters are the pioneers of data communication, com

Security company palo alto networks published "AceDeceiver: The first iOS Trojan to infect any iOS device with DRM design defects" in March 17, and spread malicious programs using Apple's DRM system design vulnerabilities, attackers can steal sensitive information from Apple users. Security researchers recommend that you immediately uninstall the AISI assistant installed on your computer and
Article Title: open-source Virtual Technology Xen is welcomed in LinuxWorld. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
At the virtualization opening conference at the LinuxWorld Conference, people were very vocal. Virtualization is attractive to open-source enthusiasts and Windows Servers users.
The forthcoming open-source Xen virtual machine technol
ultimate goal in this regard. We are increasingly finding that the previously completely isolated network functions have become the option of closely integrated basic Wireless LAN systems, this system can reshape most of the network infrastructure.
For example, many of us run independent RADIUS environments, Traffic Shaping hardware devices, enterprise firewalls, and Independent Visitor user services. All these and more components/components have become an integral part of wireless systems, big

How does a MySQL DBA get Facebook offer? (1)
We will not go into details about how powerful Facebook's technical capabilities are. It is a very challenging and interesting thing to be able to engage in technical work in such a large number of Internet companies. In fact, many programmers from China work at Facebook's headquarters. For example, the following cenalulu detailed the entire process of obtaining Facebook offer on his blog, which is very detailed and comprehensive. It is of great refe

In November, the green project was transformed into "Firstperson Limited", a wholly owned subsidiary of Sun Company, and the team was rearranged to Palo Alto. The Firstperson team was interested in building a highly interactive device, and when Time Warner
