    回复了 tomwan 创建的主题 sudo 这个词该怎么读?
    我是按 pseudo 读的

    https://www.sudo.ws/sudo/troubleshooting.html

    Q) How do you pronounce `sudo'?
    A) The official pronunciation is soo-doo (for su "do"). However, an
    alternate pronunciation, a homophone of "pseudo", is also common.
    特别是 "either A or B is true" 这种判断逻辑的情况,很有可能应该等同于 or 。

    https://en.wikipedia.org/wiki/Logical_disjunction#Natural_language

    **On the other hand, "Her grades are so good that she's either very bright or studies hard" does not exclude the possibility of both.**
    stack exchange 上的两个答案

    >It isn't always actually used with full precision, though, so, as usual, context has to be taken into account. If somebody says, "select either A or B", for example, they definitely mean that you should not select both. If they say "if either A or B is true", though, they probably mean a non-exclusive OR, and the condition is still true if both A and B are true.

    >Usually, the inclusive sense is used in mathematics and the exclusive sense in everyday life. In any case, further specification or context will remove any doubt.

    所以如果是 choose either A or B 这样那肯定就是 xor 了,但其他情况看语境也可能与 or 同义


    还有 math.toronto.edu 给了同样的解释:

    >In every day language we use the phrase "either A or B" to mean that one of the two options holds, but not both.For example, when most people say something like ``You can have either a hot dog or hamburger," they usually aren't offering you both. The use of ``either/or" in everyday English is usually divisive, and meant to imply there are only two options: A or B, but not both A and B. (The use of "or" in this way is sometimes referred to as "exclusive or.")

    >However, the use of "either A or B" in mathematics allows the option that both A and B hold. (The use of "or" in this way is sometimes referred to as "inclusive or.") For example, in mathematics, the statement "If x is a real number, then either x≤0 or x≥0" allows the possibility that x satisfies both x≤0, as well as x≥0 (which is true of the real number 0).

    回复了 luojiebin 创建的主题 大家经历过的入职体检是怎样的?
    直肠指检,楼上如果没做过的话,说明以前做过的体检都很不全面。还是挺重要的,建议每年例行体检的时候加上,虽然体验的确 …… 20 多岁已经不是小孩了,开始可能得各种病了。

    公司让你做个例行体检走流程就行,因为公司不把你身体当回事,但你自己可以当回事,不如趁这个机会做一次全面一些的体检,也就一机械键盘的钱。
