I developed a file upload sharing website and used the following code to implement the file upload function:
The Code is as follows:
We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M of fiber, that is 1M b/s =1 M/8 b/S =0.125

In addition to the limit of '123' (no more than 1000 records can be returned for query), we found that gae has a limit of '1m.
I encountered a memoryerror when using memcache to cache a large list. The error message indicates that a cached item cannot exceed bytes. I ran to the group and asked. aral also encountered the same problem. in addition to memcache, Gae has a 1 m limitation in many places (the following is translated from the Aral blog ):

During actual development, it is found that Windows CE. Net supports a maximum of 64 MB memory by default. The default value is 32 m, and the maximum value is 64 M. You can set it in the setting of Pb:
However, in actual applications, the demand for memory often exceeds 64 MB, and the current Memory price is already very cheap. It is very common to use large memory, after checking the Pb help and a b

Mbps and MB/s represent a different network transfer speed, and MB/s is 8 times times the Mbps.MBPS=MBIT/S is the abbreviation for megabits per second (Million bits by second). BPS (bits per second), which is the common unit of bit rate, bits/sec, bits/sec, transfer bits per second, data transfer rate .The size of the file is usually referred to as 8MByte. BYTE (byte) is a unit of measurement used by comput
The interchange technology of GB Code and BIG5 code
Chinese and English are different in ASCII code, which uses two bytes to represent it. In fact, the text file is saved in the corresponding two bytes per Chinese character encoding, and the display problem is automatically resolved by the Chinese operating system.
Encoding is not uniform, we use GB code, and Taiwan is using BIG5 code. The BIG5 code file ho

The memory barrier mainly solves the problem of Compiler Optimization and execution of CPU out of order.When the compiler is optimizing, the generated Assembly commands may be different from the execution sequence of C language programs. When the program is executed strictly in the C language sequence, it is explicitly told that the compilation does not need to be optimized, in Linux, this is done through the barrier () Macro, which relies on the volidate keyword and the memory keyword.
