一周最好用一次电池，长期插电源用的结果就是循环次数非常好看，然而 1 小时不到还显示 60%的电就自动关机，公司电脑就这样的

这就是我喜欢苹果手机的原因！！！！！

嵌套有何不可？

确实，现代计算机仍然摆脱不了 冯·诺依曼 架构

量子计算机啥时候能民用啊

@lastpass 喂，110 吗，这里有萝莉控

原东家直接在自家商城买显示器就行，公司不给配的，不过有金额限制，我忘了多少了，不过买个差不多的 2k 应该没问题

伪 4k，这码率顶多也就 1080p 的水平

The following rules describe how conversion occurs for comparison operations:

If one or both arguments are NULL, the result of the comparison is NULL, except for the NULL-safe <=> equality comparison operator. For NULL <=> NULL, the result is true. No conversion is needed.

If both arguments in a comparison operation are strings, they are compared as strings.

If both arguments are integers, they are compared as integers.

Hexadecimal values are treated as binary strings if not compared to a number.

If one of the arguments is a TIMESTAMP or DATETIME column and the other argument is a constant, the constant is converted to a timestamp before the comparison is performed. This is done to be more ODBC-friendly. This is not done for the arguments to IN(). To be safe, always use complete datetime, date, or time strings when doing comparisons. For example, to achieve best results when using BETWEEN with date or time values, use CAST() to explicitly convert the values to the desired data type.

A single-row subquery from a table or tables is not considered a constant. For example, if a subquery returns an integer to be compared to a DATETIME value, the comparison is done as two integers. The integer is not converted to a temporal value. To compare the operands as DATETIME values, use CAST() to explicitly convert the subquery value to DATETIME.

If one of the arguments is a decimal value, comparison depends on the other argument. The arguments are compared as decimal values if the other argument is a decimal or integer value, or as floating-point values if the other argument is a floating-point value.

In all other cases, the arguments are compared as floating-point (real) numbers.

For information about conversion of values from one temporal type to another, see Section 11.3.7, “ Conversion Between Date and Time Types ”.

换 4k

你有什么要回来的理由

先买本 c 程序设计语言打好基础再来写代码，现在的年轻人啊，还没学会走就想跑了 https://item.m.jd.com/product/12580612.html?wxa_abtest=o&utm_source=iosapp&utm_medium=appshare&utm_campaign=t_335139774&utm_term=CopyURL&ad_od=share
