Resolving a Git conflict with binary files
... i.e. --their == currently checked-out branch and --ours is the branch, usually a remote branch, or path spec you're trying to merge into the current branch. The [space]--[space] option disambiguates to path spec between branch name and path spec that both happen to exist with the same name (e.g. an...
C#位运算符（C#按位与、按位或 等） - 更多技术 - 清泛网 - 专注C/C++及内核技术
...算按位对运算对象的值进行非运算，即：如果某一位等于0，就将其转变为1；如果某一位等于1，就将其转变为0。
比如，对二进制的10010001进行位逻辑非运算，结果等于01101110，用十进制表示就是：
~145等于110；对二进制的01010101...
How do you determine the ideal buffer size when using FileInputStream?
...as well.
This is why you see most buffers sized as a power of 2, and generally larger than (or equal to) the disk block size. This means that one of your stream reads could result in multiple disk block reads - but those reads will always use a full block - no wasted reads.
Now, this is offset qu...
