converts the file open from the string to the Data Type
Json can exchange data between different languages, while pickle is only used between python. Json can only serialize the most basic data types. josn can only serialize common data types, such as list, Dictionary, list, String, number, and object type! Josn won't work. Pickle can serialize all data types, including classes and functions.
Example:
Dumps: converts a dictionary in python to a string.
Import jsontest_dict = {'bigberg ': [7600,
adjustments:
Method 1: Adjust the port occupied by Aptana:
Choose Windows> Preference... -> Aptana-> HTTP Server: Set the Build-in HTTP Server Port (s). The value range is 8200-8500.
Of course, if this is changed, you need to adjust the port number pointed to by the URL in the browser when you need to use the internal HTTP server later.
Method 2: Adjust Operation Parameters
Let Django's Development Server Run on other ports. Modify the Argument of ru
, and select "Refresh" from the pop-up menu to view the Django Project. You can right-click the menu to add or delete files and directories.
(3) Right-click the Python project and choose Properties> PyDev-PYTHONPATH> Add the DjangoProject directory (project file path) to the project code.-> OK
(4) configure the Django project: choose Django's project name-> Run menu-> Open Run Dialog-> Python Run-> right-click New-> write the project name in the Main panel, load the project name and Main Module
Title DescriptionAnother autumn, the Tautau apple tree has a fruit of n. Tata again ran to pick apples, this time she has a a-centimeter chair. When his hand is out of reach, he will stand on the chair and try again.This time with the NOIp2005 popularization group first problem is different: Tata before moving stool, strength only left S. Of course, every time you pick an apple, you have to use a certain amount of effort. Tata want to know how many apples can be picked up before sNow known n app

An article from a foreign blog describes how MySQL's read_buffer_size parameters affect write buffering and write performance.It is said that the Read_buffer_size parameter only affects the performance of write data in the following two scenarios:
SELECT into ... OUTFILE 'fileName'
When writing to the OUTFILE, the writes is buffered before writing to OUTFILE
When Filesort was used, during merge buffers and when merged results was written to a temporary file, then wr

Normally you'll see performance boost due to IO buffering on slower disks if you have IO saturation as IOs is Grou PED together to a single write; If you had good IO sub-system or when writes is almost NOOP (RAID controller caching), etc., then Buffering had NE Gative impact. Here's some stats on how many physical writes be actually posted for a simple SELECT ... into OUTFILE (file size 3849368
