Slchen's report was good, but I just couldn't understand it. I am so poor in net knowledge and so blind at web programming that I even don't know how to ask a question. This makes me feel defeated.
Victor's report is also good, but a little shallow. Maybe the effect of the meeting depends on oneself. I have used "map" and heard a lot from elevens, so it is not novel for me. Perhaps it will benefit others.
Sitting beside cr999, I learned a lot from him. We are using C++ language but we seldom have access to the kernel principle of oo programming. He want to introduce some principles of C++ programming and I think it's a good idea. Looking froward to his next report!
Generally speaking, I think it's hard to have a good balance in the selection of topic for coding group meeting. Not too deep and not too shallow, not too focused and not too general, sigh.... one word, difficult!
今天上午东北地区电网扰动实验，stream让大家都把电脑关了，以免造成什么损失。计算机系的学生，电脑关了，都不知道该干什么了，原来大家对电脑都依赖到这种程度了！！！
现在的停电给大家造成的也许就是不方便了，我却由此想起了我的青少年时代，我的漫长的中学读书生涯中，停电是让我们最感到快乐的事情。
乡下的中学，无论从师资，还是从生源上都比不上城里的中学，为了升学率，只有拼命地从时间上做文章，大搞题海战术。没有星期天，没有节假日，每天都安排得满满的，白天自不必说，早上5：30起床上早自习，晚上上晚自习到10：00，天天都像搭在弦上的箭，整个人都变迟钝了。每个人脸上都是一种表情，麻木，呆滞的表情，甚至忘记了如何去笑。停电的时候，学习的压力似乎一下子消失了，我们有了可以放松的借口了，教室里顿时尖叫，口哨，笑闹声一片。只有在这时候我才能想起原来我们也正青春年少。虽然学校的广播里传来系主任要求各个班级点燃蜡烛上自习的声音，虽然也有人点燃蜡烛，可是少有人去学习。还有人走出教室，走到走廊里大喊大叫，其中经典保留节目就是不时传来有人大喊“我是某某某，我是猪”，叫得却是别人的名字。黑暗的世界，是热闹的世界，黑暗的世界，却透出一丝光明。
时光荏苒，往事淡去，偶拾玩味，遂记之。
This afternoon, we had the first tea party of our lab. Nine candidate graduate students were introduced and then we talked and ate some snacks and then we began to become familiar with each other. So glad to see so many excellent peoples came here and the our lab are becoming stronger and stronger.
Generally speaking, this is a successful party, and a brand new style. There is only one regret for me that I can take part in it for a little few times. But I am still glad to have several chances and I surely will cherish them.
These days, I did many things that I hadn't for the past few years. I didn't because I considered it troubled or hard or some kinds of reasons else. But after I did it, I found it so easy and didn't take as much time as I thought.
From these kinds of things, I found that I always have many ideas but seldom accomplish them. This is really not a good habit, and I mush be alter and correct it. According to these days' experience, I felt greater joy from doing than only thinking. This is a good stimulation and encouragement, and it reminds me that just do it when encountering the same situlation.
Ok, then, just do it, Simply!
[引言]：遥远的路程、昨日的梦、以及远去的笑声，再次的见面我们有历经了多少的路程，不再是旧日熟悉的我有着旧日狂热的梦，也不是旧日熟悉的你有着依然的笑容。
引自：罗大佑，光阴的故事
今天中午，本科寝室室友团聚，庆祝其中的三位考上了研究生。
再次的见面，将近两年过去了，每个人都有了或大或小的变化，可是亲热如旧。
虽然中间见面次数寥寥，可是重聚的时候聊起来却像从来也不曾离开过。
一样的熟悉的爱吃的菜肴，甚至还是一样的餐馆
一样的清凉如泉水的哈啤，甚至还是一样的豪放
一样的好汉歌、霸王别姬，甚至还是一样的跑调
一样的放松、自在、大笑，甚至还是一样的无忌
可是，不一样了
因为遍插茱萸少一人，我们中的一个已经远在美国
因为马上要毕业离开，我们中的两个将去深圳工作
因为我们中的一个已经开始在讨论结婚事宜
因为我们中已经开始出现了买房，孩子之类的话题
虽然，我拒绝长大
虽然，我不懂得房价，首期之类的东西
可是，听到她们的讨论，我有些伤心地发现
我们还是要长大了，无可避免地。
因为两年的光阴如水般溜走了
因为我也要踏入社会了。
附记：很遗憾，没有带上相机，不过相信留在心底的记忆是永恒的。祝贺我的室友waiting, fishintears, flyingweed。祝福远在USA的grey, 我们依然挂念着你。感谢fishintears 和flyingweed的丰富的午饭。感谢lyh 和我们的寝室友人yh和其男友yz，感谢你们所给给过我的美好的回忆。
Today we four second year graduation students took the metaphase inspection of thesis by the three supervisors in our lab. It had been planed that every student was given 10 min to present his report including being questioned. However, when it was over, two hours passed. For each student, the supervisors evaluated his/her report carefully, from creativity, workload, and presentation. Not even a detail was spared. I was really moved by their attitude and being responsibe to us. Among their suggestions, what impressed me most is that how to present your work and research fruit. Choose a proper expressing style and not oversimplify your diagram if they includes many support. In a word, there are alway so much to learn for presenting yourself.
Metaphase inspection was over, and next time it will be the graduation inspection.
看过Gold的blog，想起了自己对于时间的利用，我的经验总结是：给你的时间越少，你会做得越快越好。后来我看到了这篇文章“时间陷阱”，发现和自己的想法很一致。铁别贴出来共享
[前言]
以前我个人的时间就管理得不好，给我的时间越多，事情却做得越少，越差。曾经考过两次GRE。第一次考试开始准备是在3月，6月末去新东方上班，11月份考试，为了准备考试，考试前几个月我特地向stream请假复习，结果却让我大失所望，所以才有了第二次的重考。第二次考试6月末报名，7月下旬开始复习，9月中旬考作文，10月末笔试，其间我不仅没有请假，7月末8月初忙着标注语料库，然后是准备“863”评测，最终评测完后的第三天进行考试。虽然结果不是很好，不过已经够用了，至少比起第一次成绩好多了。对这些经历，我也进行了反思，第一次复习时间拉得太长，我已经被拖垮了，在那段时间里，我没能好好复习考试，却也什么都没做，白白浪费了光阴，天天心情也不好，一是考试压力，二是懊悔自己管不住自己不去浪费时间。第二次，虽然压力更大，却比较充实，而且真正做了点什么，时间紧了，我没有了时间去郁闷，只能定下心好好做事情，反而做得更好了。
所以，现在我加入了很多兴趣小组；我去听报告；早上读英语；晚上跑步；写blog；阅读别人的blog并评论；看到外面天气好了就去散散步。似乎我工作的时间少了，可是比起以前不做这些的时候，我却少了那种无聊的上网闲逛，什么也不想干的无所事事的时间，时间紧了，对工作进入状态却快了，效率也高了，心情也好了，所以何乐而不为那？

英国有个历史学家，叫斯科特，帕金森，他分析了为何“大型组织大而无当，毫无生气”后，得出一个定律：“事情增加是为了填满完成工作的多余时间。”这个定律告诉我们，工作效率低，是因为我们给了这个工作太多的时间。
帕金森描述了一位老太太花一整天时间，寄一张明信片给她侄女的过程：花一个小时找那张明信片，花一个小时找眼镜，花半个小时查地址，花一个半小时写明信片，用20分钟考虑寄信时要不要带伞……就这样，一个人只需要3分钟就能干完的事情，却让另一个人花了一整天才干完，并且犹豫不决，疲惫不堪。
帕金森得出结论：“做一份工作所需要的资源，与工作本身并没有太大关系；一件事情膨胀出来的重要性和复杂性，与完成这件事情花的时间成正比。”换句话说，给自己很多时间做一件事，不一定能改善工作品质。时间越多反而越容易使人懒散，缺乏动力，效率低。一个学生平均成绩一直较低，家长只好让他修学分最少的功课，儿童心理学家却建议这个学生多修一些课。结果出乎大家意料，这个学生多修课程后，所有功课的成绩不降反升。事实上这个学生要做的就是如何打起精神，提高学习效率。

This afternoon, we had a lab meeting according to the tradition.
Firstly, Mr lu pre-addressed to us the report that will appeared in ICCC in Singapore. After Mr liu and Mr lee gave him some suggestion, he left and set out the journey. Wish him a pleasant trip!
During the time left, bill_lang gave a report about expressing the NLP results using XML. This is a great project which will influence the future of NLP siginificantly and now Bill is in charge of it. Bill's slides are comprehensive and include so many introduction, demos and tools that they impressed me greatly. His attitude and ardor toward study and work really make me pale by comparison. I really should learn from him!
This evening, before we went to running, Gold said something that set us thinking. Never show that you are weak and that you need pity, and if you did it, you would only got derision and teasing.
I don't know why. Perhaps this world is becoming more and more apathy, and maybe we are all equal and one should not ask other's mercy. In my opinion, in one's life one should not ask for pity but respect. When you are in an awkward predicament, don't try to compain but to conquer.
But I really feel pity for those people who don't understand this rule of the world. Hope they can become strong and win the respect.
I have no idea what to say, and just record it to express my joy.
Today I did one thing that I didn't in the past several years. I thought it was hard and inconvenient to do it, so I indulged myself not to have the trouble. But when I was compelled to do it, I found to my surprise that it didn't take much time and I finished it today.
I began to reflect this phenomenon, and I found I am always trying to looking for excuse for my laziness. I have many ideas in my mind, but just don't implement them. It seems that I will sharpen vigilence on this shortcoming of mine and keep self examining.
This evening, Gold, bill, bright, djl and me initiated the running group and had the evening running for the first time. We have the same aim, namely keeping fit. We planed to run two circuits of the campus, but at the first lap, djl couldn't keep pace with us and on the middle of the second lap, the same thing happened to me and gold. So we walked slowly to the playground and met bill and bright there. I also went rope skipping and other kinds of practice. Half hour passed, we finished our action for today.
This is my first physical excercising this semester and I feel very good after it. I walked upstais lightly feeling like a bird. A famous logion came to me which was inscribed on the cliff beside the Aegean sea in Greek. It said that "Do you want to become helth, then run; Do you want to become cute, then run; Do you want to become handsome, then run." Wish we can insist on and we all become heathier, cuter, and nicer.
Spring comes, and it gets warmer and warmer. The spring breeze caressed my face pleasantly. In the kindly wind, I recalled one text in the book of the primary school which are the most snug words I feel about spring. Here it is presented and then translated into English.
春风吹，
天气暖，
冰雪融化，
种子发芽，
杏树开花。
我们来到小河边，
我们来到田野里，
我们来到山岗上，
我们找到了春天。
Blowing is the spring breeze.
It's getting warmer and warmer.
Ice and snow begin to defrost.
seeds are trying to sprout.
Blooming are the flowers of the apricot.
Walking along the riverlet.
Wandering about the field.
Larking on the hillside.
Aha! by us the spring is found.
There are different trends for the same models applying on the different corpora. Looking up the data, try to find the reason.
Today there was a meeting for the whole laboratory about the standard of programming and share of all kinds of resorces. Aimed to the confusion in software development which brings out a series of problems, such as hard to maintain, control of version, repeating work and so on, several teachers and students built some standards according to the current trend of software and their own programming experience. During the period of their reports, there were also hot discussions. At last, bill_lang introduced a very good tool for the share of papers.
In my opinion, this meeting is of great importance for the future of our lab. It will not only improve the ability of software development of the students, but also faciliate the communication of the modules and the handing over of the work. I am so glad that the management of our lab is becoming more and more perfect.
又是一年植树节，无树可植，唯有追忆和怀念。
想念鹅黄嫩绿的小树，想念郁郁葱葱的老树，向往莽莽苍苍的大森林。
想起了曾经读过的几篇文章，想起它们曾经给过我的感动和向往。贴出来以示共享。
世间最美的坟墓
——记1928年的一次俄国旅行
[奥地利]斯·茨威格
我在俄国所见到的景物再没有比列夫·托尔斯泰墓更宏伟、更感人的了。这将被后代怀着敬仰之情来朝拜的圣地，远离尘嚣，孤零零地躺在林阴里。顺着一条羊肠小路信步走去，穿过林间空地和灌木丛，便到了坟墓前。这只是一个长方形的土堆而已，无人守护，无人管理，只有几株大树荫蔽。他的外孙女跟我讲，这些高大挺拔、在初秋的风中微微摇动的树木是托尔斯泰亲手栽种的。小的时候，他的哥哥尼古莱和他听保姆或村妇讲过一个古老传说，提到亲手种树的地方会变成幸福的所在。于是他们俩就在自己庄园的某块地上栽了几株树苗，这个儿童游戏不久也就被忘掉了。托尔斯泰晚年才想起这桩儿时往事和关于幸福的奇妙许诺，饱经忧患的老人突然从中获得了一个新的、更美好的启示。他当即表示愿意将来埋骨于那些亲手栽种的树木之下。
后事就这样办了，完全按照托尔斯泰的愿望；他的坟墓成了世间最美的、给人印象最深刻的、最感人的坟墓。它只是树林中的一个小小长方形土丘，上面开满鲜花，没有十字架，没有墓碑，没有墓志铭，连托尔斯泰这个名字也没有。这个比谁都感到被自己声名所累的伟人，就像偶尔被发现的流浪汉、不为人知的士兵一般不留名姓地被人埋葬了。谁都可以踏进他最后的安息地，围在四周的稀疏的木栅栏是不关闭的——保护列夫·托尔斯泰得以安息的没有任何别的东西，惟有人们的敬意，而通常，人们总是怀着好奇，去破坏伟人墓地的宁静。这里，逼人的朴素禁锢住任何一种观赏的闲情，并且不容许你大声说话。夏天，风儿在俯临这座无名者之墓的树木之间飒飒响着，和暖的阳光在坟头嬉戏；冬天，白雪温柔地覆盖这片幽暗的土地。无论你在夏天或冬天经过这儿，你都想象不到，这个小小的、隆起的长方形包容着当代最伟大人物当中的一个。然而，恰恰是不留姓名，比所有挖空心思置办的大理石和奢华装饰更扣人心弦：在今天这个特殊的日子里，成百上千到他的安息地来的人中间没有一个有勇气，哪怕仅仅从这幽暗的土丘上摘下一朵花留作纪念。人们重新感到，这个世界上再也没有比这最后留下的、纪念碑式的朴素更打动人心的了。老残军人退休院大理石穹隆底下拿破仑的墓穴，魏码公侯之墓中歌德的灵寝，西敏司寺里莎士比亚的石棺，看上去都不像树林中的这个只有风儿低吟，甚至全无人语声，庄严肃穆，感人至深的无名墓冢那样能剧烈震撼每一个人内心深藏着的感情
鸟 的 天 堂
·巴金·
我们在陈的小学校里吃了晚饭。热气已经退了。太阳落下了山坡，只留下一段灿烂的红霞在天边，在山头，在树梢。
“我们划船去！”陈提议说。我们正站在学校门前池子旁边看山景。
“好，”别的朋友高兴地接口说。
我们走过一段石子路，很快地就到了河边。那里有—个茅草搭的水阁。穿过水阁，在河边两棵大树下我们找到了几只小船。
我们陆续跳在一只船上。一个朋友解开绳子，拿起竹竿一拨，船缓缓地动了，向河中间流去。三个朋友划着船，我和叶坐在船中望四周的景致。远远地一座塔耸立在山坡上，许多绿树拥抱着它。在这附近很少有那样的塔，那里就是朋友叶的家乡。
河面很宽，白茫茫的水上没有波浪。船平静地在水面流动。三只桨有规律地在水里拨动。
在一个地方河面变窄了。一簇簇的绿叶伸到水面来。树叶绿得可爱。这是许多棵茂盛的榕树，但是我看不出树干在什么地方。
我说许多棵榕树的时候，我的错误马上就给朋友们纠正了，一个朋友说那里只有一棵榕树，另一个朋友说那里的榕树是两棵。我见过不少的大榕树，但是像这样大的榕树我却是第一次看见。
我们的船渐渐地逼近榕树了。我有了机会看见它的真面目：是一棵大树，有着数不清的桠枝，枝上又生根，有许多根一直垂到地上，进了泥土里。一部分的树枝垂到水面，从远处看，就像一棵大树躺在水上一样。
现在正是枝叶繁茂的时节（树上已经结了小小的果子，而且有许多落下来了。）这棵榕树好像在把它的全部生命力展览给我们看。那么多的绿叶，一簇堆在另一簇上面，不留一点缝隙。翠绿的颜色明亮地在我们的眼前闪耀，似乎每一片树叶上都有一个新的生命在颤动，这美丽的南国的树！
船在树下泊了片刻，岸上很湿，我们没有上去。朋友说这里是“鸟的天堂”，有许多只鸟在这棵树上做窝，农民不许人捉它们。我仿佛听见几只鸟扑翅的声音，但是等到我的眼睛注意地看那里时，我却看不见一只鸟的影子。只有无数的树根立在地上，像许多根木桩。地是湿的，大概涨潮时河水常常冲上岸去。“鸟的天堂”里没有一只鸟，我这样想道。船开了。一个朋友拨着船，缓缓地流到河中间去。
在河边田畔的小径里有几棵荔枝树。绿叶丛中垂着累累的红色果子。我们的船就往那里流去。一个朋友拿起桨把船拨进一条小沟。在小径旁边，船停住了，我们都跳上了岸。
两个朋友很快地爬到树上去，从树上抛下几枝带叶的荔枝，我同陈和叶三个人站在树下接。等到他们下地以后，我们大家一面吃荔枝，一面走回船上去。
第二天我们划着船到叶的家乡去，就是那个有山有塔的地方。从陈的小学校出发，我们又经过那个“鸟的天堂”。
这一次是在早晨，阳光照在水面上，也照在树梢。一切都显得非常明亮。我们的船也在树下泊了片刻。
起初四周非常清静。后来忽然起了一声鸟叫。朋友陈把手一拍，我们便看见一只大鸟飞起来，接着又看见第二只，第三只。我们继续拍掌。很快地这个树林变得很热闹了。到处都是鸟声，到处都是鸟影。大的，小的，花的，黑的，有的站在枝上叫，有的飞起来，有的在扑翅膀。
我注意地看。我的眼睛真是应接不暇，看清楚这只，又看漏了那只，看见了那只，第三只又飞走了。一只画眉飞了出来，给我们的拍掌声一惊，又飞进树林，站在一根小枝上兴奋地唱着，它的歌声真好听。
“走吧，”叶催我道。
小船向着高塔下面的乡村流去的时候，我还回过头去看留在后面的茂盛的榕树。我有一点的留恋的心情。昨天我的眼睛骗了我。“鸟的天堂”的确是鸟的天堂啊！
1933的6月在广州
选自《旅途随笔》
大森林的主人
秋雨下了整整一个星期。灰色的云层低低地压在大森林上面，潮湿的风缓缓地吹着。吸饱雨水的树枝垂下来。河水涨到齐了岸。我和猎人划着小船顺流而下。到了河身狭窄的地方，小船突然撞在水面下的树桩上，翻了。食物和打来的野味全给冲走了，我们只好带着猎枪上了岸。
这里离住所还很远。我们俩浑身是水，又累又饿。我冷得发抖，呆呆地望着猎人，希望他有个办法。猎人不声不响，只顾拧他的衣服。“应该生一堆火呀！”我提议，可是从口袋里摸出火柴盒一看，里面竟流出水来。
猎人还是不声不响。他在一棵枞树的窟窿里找到了一些干的苔藓又拿出一颗子弹，拔下弹头，把苔藓塞进弹壳，塞得紧紧的。他吩咐我：“你去找些干的树枝和树皮来。”
我找来了。他把那颗拔掉弹头的子弹装进枪膛，对着地面开了一枪。从枪口喷出来的苔藓烧着了。他小心地把火吹旺，把树枝和树皮一点儿一点儿加上去，不一会儿，篝火熊熊，烧得很旺。
“你照看火堆。我去打些野味来。”猎人说着，转到树背后就不见了。只听见树林里响了几枪。我还没捡到多少干柴，他已经回来了。几只松鸡挂在他腰上，摇摇晃晃的。
“我们做晚饭吧。”他说。他把火堆移到一边，用刀子在刚才烧火的地上挖了个洞。我把松鸡拔了毛，掏了内脏猎人又找来几片大树叶，把松鸡裹好，放进洞里，盖上薄薄的一层土，然后在上面又烧起一堆火。
等我们把衣服烘干，松鸡也烧好了，扒开洞，就闻到一股香味。我们俩大吃起来，我觉得从来没吃过这么鲜美的东西。
天黑了，风刮过树顶，呼呼地响。
“睡吧。”猎人打了个呵欠说。
我的眼也快要合上了。可是这潮湿冰冷的地面，怎么能睡呢？
猎人带着我折来许多枞树枝。他把两个火堆移开，在烤热的地面上铺上枞树枝，铺了厚厚的一层。热气透上来，暖烘烘的，我们睡得很舒服，跟睡在炕上一个样。
天亮了，我对猎人说：“你真有办法。要不是你，我一定要吃苦头了。”
猎人微笑着说：“大森林里，你不能像个客人，得像个主人。只要肯动脑筋，一切东西都可以拿来用。”
This evening is the time for reading group and Bill_lang gave a excellent report on feature selection. He concentrates on the FCBF algorithm which I think is similar with decision tree learning. It is a greedy procedure and may get a good subset but may not the best subset of the features. However,I still can't appreciate this algorithm. May be I should try it and have a personal experience.
Today I finished reading the proof of master theorem in the book "Introduction to algorithms". In the procedure of proof, I found a universal and useful method of solving complex problems.
At the beginning of the proof, the author neglected as more details as possible and got a most special value for the argument, then the problem seems quite simple and clear, and it was proved steply. After that, the author began to add marginal details to it and tied to transform the arguments and make them similar to the special condition, therefore, the theorem was proved true under these common conditions.
So for a problem, simplify it and find the essence to solve them, and then add some marginal conditions to generalize its apply bound.
No matter what happened and how you feel, life goes on, therefore one has to move on. One can be sad or depressed, but s/he should not forget what will be done.
Reading is passive, and writing is active.
Thinking is passive, and doing is active.
Wake up and take action!
兔死狐亦悲，惟愿峰回路转，柳暗花明。
Every one has his own free will, and one shouldn't force one's ideas upon others, especially not upon the one who is the dearest to you.
Correct the corpus to eliminate some manmade errors.
昨天晚上，寝室夜谈。pigeon说起他男友，生物识别实验室的一个博士生，刚刚中了一篇IEEE tranaction下属的一个期刊，国际A类期刊，毕业前景可期，实在可喜可贺！然后说起来她们实验室最近捷报频传，还有两个博士一个中了PR,另一个中了计算机学报的英文版。最后她感叹：“说是博士难毕业，可我看他们那些该毕业的熬了这么多年一个个文章也都发出来了”。
不过，发文章之路却甚是艰辛，2005年通知录用，实际上实验结果却是2001年做出来的。这几年历经导师的多次勒令修改，只允许投国际一级刊物，投稿后编辑部的修改再审等，终于给出的结果是在修改一下，但不用再审就录用了。苦尽甘来，毕业有望。
压力之下，硬着头皮去做，很多看上去很难的事，到最后往往也做到了。但如果没有压力，没有逼到山穷水尽的地步，人很容易放低对自己的要求，本来能做到的事情也许就做不到了。
听老罗语录的时候，其中提到钱钟书的一句话“年轻的时候，我们往往把自己的创作冲动误以为是创作才能”。现实中，我自己有这样的体会“很多时候，我们往往把自己不敢去尝试的事情误以为是自己做不到的事情。”相较而言，我们的压力还是太小。
另外一点怀疑，与本文主题无关，2001年的实验结果，2005年给录用通知，等到发表也许就2006或2007年了。5年磨一篇，总觉得还是太长了点！国际期刊相较于时代的滞后真让人怀疑其影响！
