Linux日志管理Rsyslog入门 - C/C++ - 清泛网移动版 - 专注C++内核技术
...性能上更为出色，至于孰优孰劣是个仁者见仁智者见智的问题，鉴于多数Linux发行版均选择了Rsyslog，姑且让我随波逐流一次。

...
It makes 20K requests in less than 30 seconds and uses cpu heavily. The feature might be useful but it causes too much trouble even on an intel i7 cpu

Queue.Queue vs. collections.deque
... try/except, you will end up with a busy loop eating up enormous amount of CPU just waiting for new data. This seems like a horribly inefficient approach compared to the blocking calls offered by Queue, which ensure that the thread waiting for data will go to sleep and not waste CPU time.
...
How to print the ld(linker) search path
...asic library search path, with names like sse2 corresponding to additional CPU capabilities.
These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.
One final note: using -p instead of -v above searches the ld.so cache instead.
...
Python 3.x rounding behavior
...
I saw that. And my first reaction: Who is using a 16-bit CPU that is incapable of representing all permutations of "2.67x" ? Saying that fractions can't be expressed in float seems like a scapegoat here: no modern CPU is that inaccurate, in ANY langauge (except Python?)
...
In C/C++ what's the simplest way to reverse the order of bits in a byte?
... from there is obviously simple to implement. =)
For example (on a 32-bit CPU):
uint8_t b = byte_to_reverse;
b = ((b * 0x0802LU & 0x22110LU) | (b * 0x8020LU & 0x88440LU)) * 0x10101LU >> 16;
If by “simple to implement” one means something that can be done without a reference in ...
Hashing a file in Python
...chunks the hash function finds ideal which makes it faster or at lest less CPU intensive to compute the hash function. So instead of disabling buffering and trying to emulate it yourself, you use Python buffering and control what you should be controlling: what the consumer of your data finds ideal,...
