Subject: The most popular J2SDK version is the 1.3 series. Using this version of the developer requires random access to the file, you have to use the Randomaccessfile class. Its I/O performance is far from the similar performance of other common development languages, which seriously affects the running efficiency of the program. Developers urgently need to improve efficiency, the following analysis of the source code of Randomaccessfile and other file classes, find out the crux of the proble

single. The free and PS commands are useful for estimating memory requirements. The first step of the estimate plus some security amount. Because estimating the size of a program is probably wrong because you may have forgotten some of the programs you want to run and make sure you have some extra space. There should be a few MB. (Allocating too much space is better than allocating too little, but not excessive, because not using the swap space is wasteful; see article: About increasing the swa

developed by Google, which aims to provide a relatively better compression algorithm for both speed and compression ratios.Compression test It really takes a lot of work to find out which files are suitable for data compression testing and for most Java developers (I don't want you to get a hundreds of-megabyte file to run this test).

server| concept The page is the most basic data storage unit of SQL Server, with 8KB per page in SQL Server, which means that the SQL Server database has a total capacity of 128 pages per trillion data files. Type of page: Data, index, text/image, global data distribution, page free space, index distribution image. A scope (extent) is the most basic unit of storage space allocated to a table or index by a SQL SERVER database. Each range consists of 8 consecutive pages. That is, the SQL SERVE

the sum register has a megabyte-level width, the error is still not detected. The solution to this problem is to replace the simple summation formula with more complex formulas, and this complex formula should allow each byte to be moved to affect the sum register. Therefore, we see that a robust checksum algorithm is required at least for the following two areas: widthThe width of a register can reduce this error probability to a low enough probabil

Maybe it's used to Windows, and sometimes we want to be able to load some apps automatically when Linux starts, and now we're going to do that. Load KernelAfter Lilo starts, if you choose Linux as the boot-ready operating system, the first thing to be loaded is the kernel. Keep in mind that there are no operating systems in the computer's memory at this time, and PCs (because of their natural design flaws) have no way of accessing all the memory on the machine. Therefore, the kernel must be ful

");Res.getwriter (). Print (Customer.tojsonobject ());} Can see that it actually did nothing. The Jsonobject's ToString () method, which is implicitly invoked here, does all the work.

However, the current Application/x-json is a reasonable choice. Listing 10 shows a sample response to this servlet code. Listing 10. J

service more stable transmission. From the contrast of air channel, it can be found that the GPRS system realizes the transmission of high speed Channel only through the way of channel bundle, and does not improve the capacity of the system fundamentally. The CDMA2000 system is based on the IS-95 to achieve a higher than the GPRS packet data Services, and the capacity of the system has been further increased, which actually fundamentally guarantees the upgrade from the IS-95 system to the CDM

discussing bandwidth, people often talk about "pipe Size", which is a good analogy (plus it sounds naughty): The more you pipe, the more data you can get at once.if your application needs to receive a 10 megabyte response (this is 80 megabits!). ), and you have a connection of up to MB/s, the response will take at least 4 seconds. If you have a 10mb/s connection, it will take at least 8 seconds. If other people on your network are streaming the "powe

worse. Look for "checkpoint_warning" messages in the service log to determine whether your checkpoints are performing too frequently. This message appears if the checkpoint is executed more than once in 30 seconds. The frequency of reducing checkpoints includes increasing the number of Wal files in Data/pg_xlog. Each file is megabyte, so it affects disk usage. The default configuration uses a minimum number of log files. To reduce the checkpoint freq
