One problem for users who want to equip their old Mac with a third-party SSD (SSD) is that the OS X system does not turn on TRIM support for Third-party SSDs. TRIM is a system-level command that allows the operating system to communicate with solid-state drives to determine which of the SSD is pleasing and not used, and is ready for erasure and replication. If the TRIM

Some time ago to do some of the SSD optimization work, SSD's biggest problem is that after a long time use, IO performance will drop dramatically. The main problem is that in order to prevent the "write amplification" problem, SSD firmware uses a similar log algorithm, when the storage resources are basically depleted, in each write operation firmware can only do garbage collection (garbage collection, GC) operations, This introduces a lot of time-consuming operations, such as the erasure of NAN
There are two kinds of functions in this function:the first, that is, everyone is more familiar with the removal of space.

Because of the unreasonable preliminary database design, the length of the primary and Foreign keys associated with multiple tables is inconsistent. As a result, when the fields that are too long in the primary and Foreign keys are filled with the same field, the extra part is filled with null characters. The trim () method is used in the where statement associated with multiple tables.
Because of the unreasonable preliminary database design, the len
Php learns to delete string whitespace characters. You can use Trim (), LTrim (), RTrim () functions to remove whitespace from the string masthead or end: $trimmed = Trim (String[,charlist]), $trimmed = LTrim (String[,charlist]); trimmed = RTrim (string[,charlist]); Trim () returns a copy of a string that has the beginning and trailing spaces removed LTrim () (l

Trim has nothing to say about. It is nothing more than removing the first space. For modern browsers, it is just a simple regular expression/^ \ s + | \ s + $.

ECMASCRIPT5 has defined the native Trim method for the string. This method may be faster than any version of this article. It is recommended that you use native functions in supported browsers. The following is a discussion of the problems encountered with the custom trim () function and the process of improvement. Kung Fu is constantly quenched in order to mellow.
There is no native pruning method in Java
Last night Apple released the official version of OS X 10.10.4. From the previous message, OS X El Capitan will start with a third party SSD TRIM support, but it looks like Apple will launch this feature ahead of time.
