注意：$cfg['LoginCookieValidity']的值不能大于php.ini里的session.gc_maxlifetime的值，否则phpmyadmin 里会出现“您的 PHP 配置参数 session.gc_maxlifetime (外链，英文) 短于您在 phpMyAdmin 中设置的 Cookies 有效期，因此您的登录会话有效期将会比您在 phpMyAdmin 中设置的时间要更短。”错误。

ps:我在3.4.2和3.3.3下都修改成功，3.4.2的设置，功能里面能可以直接设置，但是我的php.ini里面最大设了1440，所以设得再大也只能本次会话有效

放暑假就是我进入ACM队一周年的纪念日吧。

不知道今年能不能继续参加暑期集训，长期打酱油，怕被教练开掉啊。

不论如何，我不会放弃的。

最近快期末了，想多花点时间在学习上。

本以为这个赛季的现场赛都结束了，昨天接到njupt校赛邀请，我们学校去十几个人，我也报名了。

多参加现场赛，锻炼肯定比在宿舍里大得多。

平时得我太浮躁，很难静下心来思考困难的问题。

现场比赛倒是能够给我设定这样一个环境的，没有手机、因特网的干扰，我发现自己还是能安静想问题的。

只是，我太弱了，什么算法都不会，写模拟题的能力也不行，哎。。。

下午南邮网络赛，完全被虐啦。

一开始还不错，不到一个小时就实现了2题，rank里面还算靠前。

然后，突然就卡住了，好几道题都卡到爆，555。

直到最后一个小时才连出两题，最终以4题饮恨。

其实，这个比赛难度不大，山鬼、宇娘经5个小时的鏖战，都出了8题，偶尔卡一下，时间也不长，很均匀地就逐渐跑到rank的前两位。后面的wavwind,zlly,bearjie,都是6、7题，时间足的话也能再出题，可是4题的我和他们的差距太大了。。。不是很容易就能赶上的。

最后时刻，我围观宇娘，拍代码的速度，正确率，甚至贴测试数据的动作都比我快了许多。

差距是全方位的，我要虚心，利用暑假，好好学习。

不要再那么得浮躁了！！！

FameofLight    ACRush: Finally the god of programming arrives

ACRush    binarywithme: TC contest. 

[dasha]    ACRush: When u were beginning to compete,did u have any problems? Like low speed of sloving, or maybe some particular method u couldn't understend for a long time, sth else? If yes, how did u get over that?

下面是我的读书笔记，《短文标题，小标题》：

Beauty is in simplicity

1.阅读公认专家的编码

2.使用更短的方法 5-10行也不算极端

before your Refactor

1.起点是：清理已有的基础代码和基于这些代码写的测试

2.避开重写的诱惑（重新测试麻烦）

3.逐步增加小功能

4.新技术不是重构的理由

coding with reason

1.变量最小作用域

2.空行分割

3.需要内嵌的代码-》封装成函数

4.函数要短，古老的24行限制依然有用

5.函数参数四个以内（相关参数组合成局部对象）

6.封装且接口要窄

7.setter尽量少用

continuous learning

1.杂志、博客、微博

2.亲自编写

3.导师（最厉害的家伙）

4.看源码学习

5.午餐学习会、用户组、小范围讨论会（给别人讲授将会大大激发学习热情）

6.加入技术小组

7.参加讨论会，获得网上免费资料

8.使用播客，打发路上时间

9.《the pragmatic programmer》

do lot of deliberate practise
