手机蓝牙PIN码是什么

春节回家使用蓝牙，以前作为接收方用过一次，这一次作为发起方主动用一次，提示输入蓝牙 PIN 码，不知何意。今天搜索一下，才知道蓝牙 PIN 码相当于是通讯双方的联络码，随意的四位数，例如 A 机输入 0000，B 机也输入 0000，双方就可以建立连接了。

对我们最有害的是怨恨、批评和内疚 ( 思考 )

春节回家在火车上看《读者》时读到的一句：对我们最有害的是怨恨、批评和内疚。

工作有压力才有动力？ ( 思考 )

这不是绝对的，可能有些场合是如此。自从参加工作以来，从我所从事的职业角度出发，我越来越反对这一说法。今天正好录到一篇：《减轻压力是否更有助于发挥聪明才智？》

以下场景多久会出现一次？一个 IT 项目团队一开始能够有效地协作。三个月之后，他们都变得焦躁不安，并且因为小事而相互指责。团队成员可能会体重上升、重新开始吸烟、与家人出现矛盾或出现睡眠问题。这都是压力过大的表现。

The Old Woman and the Physician
from http://classics.mit.edu/Aesop/fab.1.1.html#642

An Old Woman having lost the use of her eyes, called in a Physician to heal them, and made this bargain with him in the presence of witnesses:

that if he should cure her blindness, he should receive from her a sum of money; but if her infirmity remained, she should give him nothing.

This agreement being made, the Physician, time after time, applied his salve to her eyes, and on every visit took something away, stealing all her property little by little. And when he had got all she had, he healed her and demanded the promised payment.

The Old Woman, when she recovered her sight and saw none of her goods in her house, would give him nothing. The Physician insisted on his claim, and. as she still refused, summoned her before the Judge.

The Old Woman, standing up in the Court, argued: "This man here speaks the truth in what he says; for I did promise to give him a sum of money if I should recover my sight: but if I continued blind, I was to give him nothing. Now he declares that I am healed. I on the contrary affirm that I am still blind; for when I lost the use of my eyes, I saw in my house various chattels and valuable goods: but now, though he swears I am cured of my blindness, I am not able to see a single thing in it."
