向来是反射弧超长的那类人，当所有人都开始展望2008的时候，我的2007似乎还没有过去，对着*.log.2008-01-07的无奈，不得不开始盘点2007

 

1)工作篇

丰收？歉收？ 成功？ 失败？ 都是他妈的扯淡。工作的人说什么成功失败，不过是工作罢了。总想总结自己这一年学会了什么，学会了php,学会了java，可以玩转oracle,mysql, 各种各样的程序写了一个又一个，不眠不休的工作忙了一天又一天，真想骄傲的对自己说，真充实阿，学会了这么多东西？真的吗？扯淡，自己骗自己罢了，在这个技术狂飙的时代，这些东西只能让你做一块更合格的砖而已。 不过牢骚归牢骚，值得肯定的是，终于完成了从学生到民工的心理转变，明白什么是工作，即使有些事情一点也不感兴趣，也要装做自己很喜欢，努力的去做，直到最后自己都以为自己真的喜欢上它，不能不说是一种进步。耐得住寂寞，学会快乐，有她的鼓励，坚忍许多。好多人都喜欢说快乐的工作，学习这一点，花了一年，有点儿长，总算值得。

 

岁末年终，开始学习管理，还没有完全适应这种忙于协调和调研的工作方式，但终归是一种新的生活方式，更新奇也更刺激，看着outlook上一堆堆的未完成任务。显然，一切才刚刚开始。

 

题外话：听说，视频死了，死于2007岁末，比起夭折于2006的无线，这种狂舞于生命最灿烂一瞬的死亡，来得更加突然。有点儿冷，或许唇亡齿寒，或许遗憾没能在旋舞的最后疯狂中分一杯羹。机会稍纵即逝，我能抓住的，能有几个？

 

2007，什么也没有学到，只是学会了工作。2008呢？

嗯，可以同时发几个博客了，不错不错

最近打开msn space总是很慢,有时候干脆打不开,郁闷,准备在blogger上开一个新博了,

有时间就同步更新这里,没时间还是以那里为主了, 欢迎各位好友光临:)~

 

忽然想到,按照好友名单分类整理blog或许是个不错的功能,谁有类似的软件没有? colin的那个博鸽是不是可以?

又是一年愚人节，除了被她小小的欺骗了一下，没有骗人，也没有被骗，出乎意料的平静，静到有点冷。圈子一点点的改变，直到一点触发，才惊觉物是人非，怅然。

 

周末去看了张国荣的纪念专场，纵横四海＋霸王别姬。拷贝的质量很差，但是毕竟能在电影院中重温昔日的经典，已属难得，还强求什么呢？如老婆所说，张是一个漂亮的男人，特别是和发哥演对手戏的时候，才让你直到帅和漂亮是多么不同的两个词。而霸王别姬中的他已经彻底入魔，段小楼说程蝶衣：不疯魔，不成佛。程蝶衣可以说已经和虞姬这个角色契合到了极点，所谓人戏不分的境界。而张之于程，似乎也有几分这样的意味。很多人都感慨，人生如戏，那么在哪幕戏中演主角，似乎并不是十分重要。

 

最近压力很大，以致于常常走神，失眠也渐渐不期而至。希望能找个机会出去放松一下，住在紫竹院附近，却一直没能进去转转，但愿这个星期能够成行。

又一个周末过去了，本打算好好休息一下，结果发现事情很多，只能马不停蹄的加班，终究还是没能出去走走。

 

家里dvd机坏了很久，拆开两次，试图修一下，未果。周末终于痛下决心，去苏宁抱了一个新的步步高回来。冲动往往没有好结果，新的dvd迅速抢占了本属于PS2的YPbPr接口，俺的生化危机只能去找可怜的av接口，模模糊糊，戚戚惨惨，倒是很符合画面要表现的感觉。昨天晚上第二次生化危机再次通关，这次总时间提高了到了13个小时，可是看到人家攻略上提到的2小时40分，汗颜。

 

新的一周，开始新的努力。在公司工作应该更积极一点儿，主动一点儿，总是等待不是好事。帮冯师兄弄的东西已经有了眉目，回头给他整理一下代码。VC版有太多文章没有整理了，今天晚上好像应该过去清理一下，既然做了这个版主，怎么也要负责一点儿的:) 想来事情还是蛮多的，加油啊加油！ 立此存照，免得自己又忘了。

和老婆一起看了中央台的315晚会，里面揭露的侵权事件，件件让人寒心。想起前日看到Teddy的博客中对千百年来勾心斗角的厌恶，忽然觉得自己也对这个充满尔虞我诈的世界悲观起来。继续和老婆讨论所谓的80后的问题，我们几乎是没有信仰的一代人，这很可悲。在这片精神的废墟上成长，注定性格上的脆弱和内心的寂寞，拜金，叛逆，摇摆不定，不过是表现形势而已。

 

感慨归感慨，坚强还是要自己慢慢学会，没有的信仰也要自己去找。

 

今天终于搞定了database的均衡问题，心情相当不错，明天做一点儿优化工作，整理一下文档，这个项目基本上就收工了:)

 

 

她去参加同事生日报告，未归。

 

在公司完满的解决了session跨域的问题，看看手机，已然8点多了。带着家里寄来的包裹，匆匆的赶着回家。路上听着出租车上无聊的广播节目，总是纳闷，为什么会有那么多人发短信参与呢？人最害怕的终归是无聊二字。望着窗外熟悉的景物，忽然会有一种陌生的感觉，仿佛自己是第一次来到这座城市。日复一日，单调的节奏下，锐气慢慢消退，压力却从不曾减少。梦里惊醒的次数日渐增多，转日却不再记得缘由。透支未来，对自信者是一种激励，对怯懦者是一种折磨，于我，二者兼有。

 

乐乐仿佛知道它今天会有一条新的领带，所以迫不急待的把旧的一条弄脏，顺带送我满手的腥臊气。在没有灯光的楼道里，不慎踩到它受过伤的脚，发出一声嘶叫，一腔怒气化为乌有。毕竟，三角形是最稳定的结构，这个家，因为它的存在，少了很多针锋相对，多了许多的和谐。也许是我对它太凶，即使现在家里只有我们两个，它仍然傻傻的趴在外间门旁，等候她的归来。她说我将来亲子关系会很成问题，我也渐渐开始担心起来。

 

在学校的时候我是宿舍里最喜吃泡面的，每次熄灯后，总要吃碗泡面，才肯睡去。还常常诱惑江表，小木一起过这种极度不健康的生活方式。结婚之后似乎再也没有吃过正儿八经的泡面，即使吃方便面，也是她动手煮的。难得今天有机会自己用最简单的方式泡一碗，康师傅，红烧牛肉，几乎是最经典的方便面。味道依旧，却没有了当初的食欲，胃已经习惯了她的手艺，经不起我粗糙的折磨，抗议不止。时光入水，改变又岂只是我的胃？

 

和师弟抱怨了一阵生活的压力，忽然觉得轻松很多。很多时候，压力客观摆在那里，你总是躲躲闪闪，不敢正视它。而一旦坦然面对，就会发现，担心也不会让它减少分毫，不如切实走好脚下的路。有时候想想，自己还是太幼稚，但能够坦然的面对生活，谁又能时时刻刻的做到呢？

 

希望明天能够搞定database的均衡！

 

 

凌晨1点，刚刚赶好明天要交给老大的一份报告，疲惫的身体却无法催眠毫无睡意的大脑。昨天看生死搭档，何冰说，一个人到了年纪，睡觉也是很奢侈的一件事情，不知道我将来是不是也会这样。

 

周六终于打穿了生化危机4，可恨的盗版盘在最后的关键时刻频繁重启，气恼中，几乎将手柄摔烂。结婚大半年，脾气似乎好了很多，不在与人争辩，也很少愤青，最多在打游戏的时候对自己发发脾气，当作解闷。看小说，看到双眼充斥着血丝，打游戏，打到拇指上长出水泡，磨出老茧。最后，还得无聊二字。计划中的很多事情还都没有做，2007的第一季已经渐进尾声。前日，m说要开始学车，开始准备买房了；江表房子已经弄好，住进了北苑；徐璐更是当上了爹，每日在换洗尿布中学习人生的真谛。每个人都有自己的路，也都在努力的走着，很好。

 

上周去上海，本来计划去看看godsix和rongy，结果人算不如天算，没能成行，又是一桩遗憾。最近情绪颇为低落，不知为何，开玩笑说，其实自己蛮有文学青年的天赋，伤春悲秋。同样的境遇有时让人感到绝望，而有时却能让人发狂。对此，她似乎也有所察觉，又生出些许误会，于心不忍，却不知该如何解释，其实不过是一段低潮罢了，活着总是这样，有波峰就有波谷，就像female的生理期一样。潜龙在渊，蓄而不发，仔细思考未来的路，虽然依旧毫无头绪，总好过胡打乱闯。

 

春天来了，或许该是出去锻炼的时候了，中午吃饭时，偶尔翻钱包，发现一张浩沙的健身卡，似乎很久没有去光顾了。苦笑的看看满身的赘肉，又一次下定决心，减肥。

 

看着房间里甜甜睡去的她和它，忽然觉得自己的路也不是那么难走。我也在努力的走，和她一起，想想，其实很好。

 

 

 

 

昨日中午接到通知，五个小时后已经在飞机上品尝没有鸡肉的鸡肉饭。偶尔认识了一个正在学汉语的美国哥们，侃得昏天黑地，尽管彼此都无法准确的理解对方，却也使乏味的旅途变得不那么单调。和一个新认识的同事住一个标准间，发现自己突然很喜欢聊天，或许是最近很少出来腐败的原因，好容易逮到机会，大侃特侃，凌晨两点才意犹未尽的去见周公，混不觉一日奔波的辛苦。

 

今天上海的天气还算不错，有点儿小风，但是太阳很好，从静安赶到张江，再折回人民广场，舟车劳顿中浪费了大半的时间和精力。洗手时忽然发现戒指遗忘在酒店，心中忐忑不安，精神恍惚。终于还是忍不住，告了假，回去找到戒指，方始心安。平时从来不带戒指出门，今天才发现，这枚戒指，依然是那么的珍贵。

 

据她说，乐乐很像我，脾气暴躁却性格温和，实在不明白这是怎样的矛盾统一。反正如果我是一只西施的话，那绝不会去招惹一只拉布拉多，爱情失败，身心俱伤，哈哈。

徐睿 八斤二两，我们宿舍的老大果然事事领先！祝小朋友茁壮成长:)

 

不知道是毕业的原因，还是成家的结果，这个春节突然特别想对所有的朋友们都说一声新年快乐

长大的人总喜欢怀旧，或许如老婆所说，我现在看起来像个小老头了，连心态也老了起来

连续的丢了两次手机，通讯录已经残缺不全，想尽方式给能看到的人一份祝福吧

祝我的所有朋友，猪年快乐，心想事成！

 

 

周末，m和yangf在家中做客，偶尔说起，才想到转眼下周又是一个圣诞，紧接着又是一个happy new year，不得不感慨时间过的太快，又是一年匆匆而过，转眼又是做一年总结的时候了。还没想好今天总结些什么，唯一的感觉就是忙碌，几乎没有时间用脑子来想自己是在做什么，只是不停的做一件又一件必须去做的事情，回头看来，原来做了这么多大事。买房，装修，毕业，结婚，工作，旅游......

 

许多事情开始变化，比如几乎不再看漫画，比如很少去踢球，比如看小说的时间越来越少，比如开始认真地考虑职业规划

许多事情依然没变，比如我的体重，比如享受美食的快乐，比如依然喜欢和一帮同学聚在一起，比如我对小猪的感觉

 

忙碌的一年很值得纪念，或许白发苍苍的时候回顾这一生，这是最有意义的一年，当然，也可能是被我遗忘的一年

 

花一点时间，去整理这一年，给自己一个交待。

 

刚刚在msn的焦点消息上看到微软捅出来一个国内十大流氓软件，仔细一看，似乎除了HDTBar之外，偶都中过n次的说

现在的流氓软件的确做得比较讨厌，而且还有一帮无聊的人居然还把这些东西打成合集，到处传播，上次不小心中了一个61个

流氓软件的大合集，用了n种专杀工具才搞定的。

 

不过话说回来，流氓软件如何定义这个问题也比较难解决，前两天写了一个bho，让自己的ie个性化一点儿，结果朋友一装上就说我这个是病毒，是流氓软件原因很简单，bho嘛，不就是流氓软件咯。想想不由得一阵苦笑，bho本来是微软为了大家更方便的定制个人爱好的ie准备的编程接口结果现在却成了过街老鼠人人喊打，真是冤啊，比窦娥还冤。

 

很多好用的工具其实都是双刃剑，bho就是如此。用来定制自己的ie，添加自己需要的实用功能，非常方便，可是如果用到歪路上，就会让你苦不堪言。说到底，还是用自己的bho踏实，btw：刚刚又用safe360查了一遍，不知道什么时候又被baidu搜霸给流氓了，佩服！

微软昨公布中国十大流氓软件名单
◇字体：［大 中 小］  发表评论 来源：北京青年报(06/12/06 03:31) 

　　本报讯　昨天，记者从在新西兰奥克兰举行的国际反病毒大会AVAR2006上获悉，美国微软公司安全研究响应小组正式发布了“亚太地区间谍软件的情况对比”报告，其中CNSMIN（3721）位居我国十大间谍软件的首位，而且其感染率也占整个间谍软件（“流氓软件”）的半数以上。

 

　　微软公布的中国内地十大“流氓软件”排名如下：CNSMIN（3721）、CNNIC Chinese keywords（CNNIC关键字搜索）、Baidu.Sobar（百度搜霸）、Sogou（搜狗）、Baigoo（百狗）、DuduAccelerator（DUDU加速器）、Caishow（彩秀）、DMCast（桌面传媒）、HDTBar （一种网页工具条）、Real VNC（一种远程控制软件）。

前面左子问AMF这个东西是干嘛的，说实话我也不知道Macromedia搞这么个东西干嘛......而且字节序还是little-endian的，读起来非常麻烦

上个星期看SWF的specification,这个星期看FLV的specification部分，发现FLASH开发组这帮人完全是在秀他们的设计能力，同时考验俺们这些读者的理解能力。（btw：从学校出来之后发现英语水平下降很快，sigh！）

 

flv文件的基本结构是

文件头 + tag1 + tag2 + ...tagN

 

文件头:

46 4c 56(FLV)+01(版本号)+05(tag类型标志位）+保留字节00+ 结束标记(00 00 09)+ 4个字节00 00 00 00

 

tag

tag类型(1字节,0x12为MetaData, 0x08为Audio，0x09为Video）+

tag大小三个字节 （搞不懂为啥一定要三个字节.....省空间也不是这么省的阿...) +

time stamp时间戳，三个字节（又一个三字节:(）+

extend time stamp 扩展时间戳 一个字节 +

stream id 00 00 00不知道啥意思...+

tag内容

 

MetaTag内容

就是一个AMF包，用上面提到的AMFReader读取即可，很多文件都缺这个东西

 

AudioTag内容

1个字节的Audio标志（8个标志位居然都用上了...) + 具体音频数据

 

VideoTag内容

1个字节的Video标志（4bit桢类型，ft，微软拼音居然没有巾贞字，4bit编码类型）+视频数据

 

基本上就是这些东西了

 

应左子要求，贴今天新写的一个AMF Reader用的头定义

本部分程序根据sourceforge上的soledit中的AMF模块修改
