I don’t what the others think, but I feel disappointed only, for the MCM2007, we end it with such a style, what a shame.
I only wanna sleep for a whole day now.

This Term Is Over
With the end of the final-exam of Algorithms, this term is over, say goodbye to manythings, and there is so many things need to do.
I wish there will be a full mark to end this term, which I did the best in our course.
内网服务器终于弄好了
跟董老师说让把后面另两台机器的还原卡给去了, 然后都装上了 RHEL AS4, 按计划, 一台给内网做服务器, 提供 http, ftp, 打印 等服务, 同时准备留给未来做 PC2 的服务器, 另一台做 OJ 的测试服务器.
今天弄内网服务器弄了半天终于搞定, 麻烦死了, 最后发现问题都在那个该死的防火墙上.
一开始配打印机, 一开始没插电, 系统没找到, 等找到后设置成共享, 其他机器却不能访问 查了一下 Google/Baidu, 启动 samba 服务后还是不能访问, 以为是 samba 配置的问题, 查询了无数的东西后突然想是不是防火墙有问题, 关闭后就 OK 了, 无语. 按照 linuxsir 上的介绍, netstat 查看了一下 smb 的端口, 然后在防火墙中打开这两个端口, 搞定.
然后启动 ftp, 跟在外面那个服务器一样的启动 vsftpd, 写配置, 发现又不能访问, 怒… 通过查看 FlashFXP 的记录发现最后调用了一个很奇怪的端口, 65xxx, 想了一下估计又是被服务器拦了, 一怒之下索性把防火墙关了, 懒得去管端口设置了.
最后启动 http 服务, 这个很容易, 乱搞就搞定了, 不过默认好像是不启动 httpd 的, 又要自己开了一次. 一切搞定 :P
那台准备用来做 OJ 测试服务器的机器还没开始配, 看看明天上午有空就把 OJ 在上面跑起来.
继续 TopCoder
回头看了看, 把分类 “集训感受” 改成了 “竞赛人生”, 是啊, 其实一直都生活在各种竞赛中, 与其消极规避, 倒不如正面对待.
今天上午 TopCoder SRM 336, 没钱的比赛, 本来也不想做的, 后来想想反正无聊, 继续吧. 不过第一次 Div I 的比赛就做的奇挫无比… 250p 卡在了输入上, 一个小细节很久后才调整过来, 500p 想了很久实现, 不过做出来的分数也还好, 900p 没空做了, 开了发现是个非常非常麻烦的计算几何, 求一点对一个立方体在某平面上的投影面积. omg. 没被人 cha 掉, 也没去 cha 人, 没什么好 cha 的. 可惜在 System Test 里两个题都 Failed 了, 看了看一个是段异常, 还是不知道自己哪里弄错了, 看了看数据貌似也只是有点大而已, 其他倒也没什么, 另一个估计算法实现还是有问题, 在一个很特殊的情况下错了.
从 13xx 分掉到了 12xx 分, 太失败了, 下次做好点, 不然又回到了 Div II, 虽然可以拿钱, 不过 Algo 的钱也最多算零花吧, 玩玩还可以.
The Lake House
The Lake House, or the Chinese name Chu Bu Dao De Lian Ren(触不到的恋人) of this film, make me to spent 2 hours on it.
I was puzzled why the name is Lake House but Untouchable Lover, then a dictionary told me that Untouchable is not a good word, and now I think Lake House will be more better.
There is a story about a couple of lovers, who apart by the time, absolutely two years. The only way to connect them is the mailbox in front of the lake house, a magic mailbox which can connect two years. But after a period, with something which makes the love uncertain happened, the lovers really separated then. Luckily, there is a good ending of this movie, they meet each other at the mailbox of the lake house.
It sounds like another movie based on the Jimmy’s book Turn Left, Turn Right, anyhow, better later than never.
Kitty is Back Hunan Now
But still a long time to get home, I suppose that she is in HengYang now, and to get 2513 or 1561 to back Dong’an. Wish a good night that arrive Dong’an, and back home in the next morning, then have a excellent lunch.
The Kitty is Back Home Now
Nearly 24 hours travel from Chongqing to Zhuzhou by K73, then change to 1561 or any other train which passed Zhuzhou and will get Dong’an for about 6 hours. A long time, but can get home, a happy family, and delicious foods, happiness is just like this.
Wish a good trip, and wait 20 days, then I’ll be back.
I’ve edit a photo of her for post, but canceled this opinion then. the kitty is my own, the life is our two’s, so I left it on my computer. :)
Wires 的钱都没赚到
前天晚上做的 SRM335, 终于从万劫不复的 Div II 跳到 Div I 了, 不过很郁闷的是 500p 还是挂了, 貌似是我初始化的问题, 本地的 MinGW 编译器跟 TopCoder 上的不太一样, 早知道就直接写一个 10^18LL 好了
房间第一奖金 $27.00, 比上次房间第二都少, 无语, 刨税后连 Wires 的 $20 都没有, 无语.
TopCoder 终于进 divI 了
不容易啊. 在蓝绿边缘挣扎了那么久, 终于变蓝了. 做了个房间第一, 不过还是不够理想, div Summary 到了 22th 还是 23th 吧, 500p 的挂了, 莫明其妙的挂了, 本地测是对的, 结果 system test 直接被第一个 Sample 给弄挂了.
anyhow, 变蓝了, 不过可能升的很慢, 因为前面一直做太挫, 并且貌似是有刀的, 还没到帐…
Life Is So Fragile
Yesterday a sophomore in our school dead because a traffic accident, sigh~
