The user is worried that the solid-state hard disk downloads things easily bad, is actually worried about the SSD life problem.

) each time a 1 Revisedobjectinheap object is created, but it consumes 2M of out-of-heap memory. Such a heap of memory is sufficient (in which case garbage collection of heap memory is not performed), but the out-of-heap memory is insufficient, so OutOfMemoryError is not reported . Although the improved REVISEDOBJECTINHEAP does not have an out-of-heap memory leak, this workaround wastes heap memory unnecessarily. A simple look at the next Bytebuffer source, its internal allocation of external me

folder. Version 5.4 can be used directly with Application.streamingassetspath. The previous version requires the use of Application.datapath + "!assets/" + filePath; Because Streamingassetspath with jar://, this is to the WWW URL path, and LoadFromFile interface need is the actual path (without jar://or file://). Note!assets/This place is behind the exclamation mark. There are all kinds of writing on the Internet, only this is correct, pay attention to the details here.Iv. Project works address

, Shared libraries and open files (handles). This should also mean that the process has opened the file, then the thread shares the open file. If the parent process has opened the file before calling fork, the child process after fork has a copy of the parent process descriptor. The parent-child process shares the same open file collection, and therefore shares the same file location. This is the same situation as the main thread has open files, and the FD is passed to the startup threads. A

this transaction is not finished, another transaction accesses the same data. Then, between the two read data in the first transaction, the data that the first transaction two reads may be different because of the modification of the second transaction. This occurs when the data that is read two times within a transaction is not the same and is therefore called non-repeatable read.illusion reading: a phenomenon that occurs when a transaction is not executed independently, such as when the first

, in Python, variables are based on content rather than variable names in C, so as long as your digital content is 5, regardless of your name, the ID of the variable is the same, and it also shows that a variable in Python can be accessed with multiple names.This design logic determines that the value of the numeric type in Python is immutable, because if, as in the above example, both A and B are 5, when you change A, B will also change, which is certainly not what we want.Therefore, the correc

Opening Empty is the color, and the color is empty.Empty and empty, in the Ruby language, everything is an object. Ruby is an object-oriented language (object oriented Language), and the object-oriented concept is much more robust than other languages. The raw type data and object type data in Java are not present in Ruby. Most of the stuff in Ruby is an object. So, to master the metaprogramming of Ruby and Ruby, the object is the first compulsory lesson. This is the time to focus on the obj

this algorithm, the value of Ssthresh is EST_BD * MIN-RTT (minimum RTT value), if the packet loss is caused by duplicated acks, then CWnd = Ssthresh if Cwin > Ssthresh. If it is caused by RTO, CWnd = 1, enter slow start.
