Equinox is an osgi Implementation of eclipse, and later versions of eclipse3.1 are all started through it.
You can download the latest equinox version from the eclipse website at http://download.eclipse.org/equinox /. If you have installed a version later than eclipse 3.1You can findOrg. Eclipse. osgi_3.2.0_xxx.jarThis is the implementation file of equinox.
HereArticleWe useOrg. Eclipse. osgi_3.7.2.v20120110-1415.jarFor example.

First, the basic use of synchronizedSynchronized is one of the most common methods for solving concurrency problems in Java, and is the simplest one. There are three main functions of synchronized:(1) Ensure thread-mutually exclusive access synchronization code(2) Ensure that changes to shared variables are visible in time(3) Solve the reordering problem effectively. Syntactically speaking, there are three ways to use synchronized:(a) Modification of common methods(b) Modification of static meth
1. Mixed wireless networks often fall off the line
Failure phenomenon
Use the Linksys WPC54G network card and Linksys WRT54G AP to build a wireless LAN that uses IEEE 802.11G protocols and a few 802.11B network adapters. The line is often dropped when using wrt54g for 54mb/s connections.
Fault analysis
In theory, the IEEE 802.11g protocol is backward-compatible with the 802.11B protocol, and devices usi
Some of the parameters in Equation 1 are set to constants. First, the interval between packet reception and acknowledgement of message transmission is defined as 12 symbols in IEEE 802.15.4. In 802.15.4, a symbol is 4/240ms, so ta=48/250=0.192ms. Second, the IEEE802.15.4 receiver is able to reliably detect a confirmation message (a 4-byte long pilot code and a 1-byte long frame delimiter before the message is confirmed), so td=40/250 is required t

Printer Port Selection
Microsoft Windows Server 2003 provides built-in support for the following network port types:
•
Standard TCP/IP Port Monitor
•
Lpr print monitor
•
Appletalk printing Monitor
•
HTTP print monitor
Note:Hewlett-Packard printer port is unavailable in Windows 2003
Windows Server 2003 also supports the following local printer ports:

determined by the symbol as the 0 of the divisor.Recalling our introduction to Nan, when 0 divided by zero, the result is not infinite but NaN. The reason is not difficult to understand, when the divisor and dividend are close to 0 o'clock, its quotient may be any value, so the IEEE standard decided at this time to use NaN as a quotient more appropriate.5, special values: We already know that the exponential field can actually be expressed in the ran
The floating point in the computer memory.Introduction of the Floating Point concept
In the development of computer systems, we have proposed multiple methods to express real numbers. For example, in the fixed point representation, this representation is used to fix the decimal point in a certain position, for example, 11001000.00110001. The 16-bit (2-byte) fixed point represents the integer part with the first eight digits, the last 8 digits indicate the decimal part. This method is intuitive,

the Internet by filtering unnecessary transmission in the network.
For example, when the fddi site has a message to be sent to the ieee 802.3 csma/cd network on the internet, you need to complete the following work:
· The site first transmits the message to the llc layer and adds the llc header.
· Send the packet to the mac layer and add the fddi header. The maximum length of an fddi packet is 4500 bytes. packets larger than this value can be sent in
Dennis Ritchie a time-sharing operating system developed on the DEC PDP-7 small computer in the summer of 1969. Ken Thompson developed a prototype of the UNIX operating system in one months in the summer of 1969, during his wife's return to his hometown of California, in order to run his favorite Space travel game on an unused PDP-7 computer. At that time, bcpl language (basic combinatorial programming language) was used, and after Dennis Ritchie was rewritten in 1972 with a very strong transpl
analysis
The wireless AP generally has only one LAN interface, therefore, when the wireless AP is connected to the network, it will occupy the network interface used by the original host, unless the broadband router has more ports, the wireless AP and the original host can not be connected to the broadband router, thereby sharing the Internet connection.
Fault resolution
If there are no more ports available for broadband routers, you can purchase a wireless router, a WAN port to a broadband

Not very strictly speaking, tier-1 can be admirable, tier-2 can be respectable,
Because Ai has a lot of related meetings, it is also good to list the tier-3.
