external cannot reference the variable inside it,So it will be released soon after execution, and the key is that this mechanism will not pollute the global object.2 Cache To take another example, imagine that we have a function object that is time-consuming to process, and each call takes a long time,Then we need to store the computed values, and when we call this function, we first look in the cache, and if we can't find it, we do the calculation.It then updates the cache and returns the val

a subpool, and the request to the next subpool---too small subpool fragmentation problem may be more serious--ora-4031 more likely to occur. Too much subpool can also lead to higher management coordination costs. For example, the following error is related to Subpool: ora-04031:unable to allocate 4216 bytes of shared memory ("Shared Pool", "Unknown Object", "SGA Heap (2,0)", "Library cache") Shared Pool Size judgment LRU chain table is divided into two: transient LRU (instantaneous LRU),

The difference is an exclusive operation, that is, '1'. The same operation is '0', similar to a mod2 operation;5. jne/jnz, je/jz, jmp: jne and jnz are the same thing. When the zero mark is ZF = 0, the jump will be made; When ZF = 1, je and jz will jump; jmp will jump at any time;6. call/ret: used for function proc

In our case, this will have "Surfaceflinger" done, it (Surfaceflinger) is an Android software image synthesizer, or through a hardware synthesizer in the platform. Naturally, if the operating system or hardware platform changes the actual work of these instances will change over time but this principle will probably stay for a while.The final step of synthesis is done at the kernel level through hardware image synthesis (called Mobile Display

trading groups have tried the definition of "Big Data" and its differences from "common" data, and the conclusions are slightly different, because all views use big data features (3 V, 4 V, etc.) to describe them, but there is no more involved definition itself. As of the release of this Guide, the 3v model (volume, velocity, and variety) is still the most popular definition of big data. A new definition of "Big Data" is as follows: Big Data can use summarized statistics, and its data volume ca

sloc (single line of code), kloc (thousand lines of code), lloc (logical line of code), and ploc (physical line of code), ncloc (non-commented line of code), DSI (delivered source instruction ). Sloc and kloc are commonly used. The code line analysis method is meaningful to technicians because it does reflect the size of software from a program and is physically measurable. However, this method also has the following problems. L in the requirement, p

I. version count description This issue is described in the MOS documentation. For details, refer to [ID296377.1]. All SQL statements in Oracle are implicitly sharable. When a user submits an SQL statement, RDBMS performs a hash operation on the SQL statement and then generates a hash value, compare the hash value with the existing SQL statement in the shared pool. If the hash value is the same, reuse the previous SQL statement cursor. If the hash value does not exist, perform hard parsing. Duri

draft language, and he can verify and express a software in a simple way, the second is a verification measurement method. QA can use it to quickly determine the results of the module.For building DSL, you will have to design your model and then use it (run time phase). Microsoft will offer a complete suite for building DSL (you can try the beta now !), And will also offer some pre-defined dialects for usage in their tools. I see Microsoft DSL vision more as a "configuration language" building
