第二届网络大赛初赛测试

今天带队员们进行了初赛的测试,让队员们感受了一下在高压力情况下1小时完成150个不定项选择题。

坦率的说,队员们的发挥没有我想象的好,做题的速度仍然没有达到预期的要求,和他们一起答题需要我集中精神全力参与。

我在反思,对于这次的比赛我是否太功利了。我很清楚这次的比赛的名次对于学校、对于信息安全专业、对于网络学院,当然也对于我自己都会产生不小的影响。我该坚持这样全力投入,还是只是把这个比赛只是当做一个game呢?

幸好还有希望,尽管只是一线的希望…… 

统一通信平台

今天听了Cisco关于统一通信平台的介绍,这是我第一次接触统一通信平台方面的产品,以前只是接触过独立的IPT方面的产品。感觉这个产品虽然只是一系列产品的整合,但是经过整合之后的效果是全新的。不知道其他的厂家是否有类似的应对方案。

The layers of network hell

Backspin By Mark Gibbs, Network World, 06/26/06

Brothers and sisters! We are in Internet hell, and I, the Rev. Dr. Mark Gibbs (let me hear you say, "Howdy, Rev!"), am here to show you the way to salvation!

To escape Internet hell you must first understand it. According to Dante, hell (the biblical kind) has nine circles. Internet hell is somewhat less complex. It’s made up of layers rather than circles, and only seven of them at that (natch). On the other hand, compared with Dante’s vision, Internet hell is truly, er, hellish.

We start at the outermost layer of Internet hell, the Layer of the Unknowing. Here you will find the lost souls of the newbies who know not why they are there nor where they are nor what time zone they are in. They do know, however, that Mrs. Princess Mawa, a widow in Cote d’Ivoire, needs their assistance in a business relationship regarding the transfer of $10 million.

Newbies are ferried across the river TCP/IP by the ferryman AOL. Clouds of spam rain down on the newbies, and howls of anguish rise up as they are compelled to press the Y in response to the question "All files in directory will be deleted! Are you sure (Y/N)?" Let me hear you say, "Where’s the Any key?"

The next layer of Internet hell is the Layer of the Lustful, reserved for the spammers, the phishers, the hackers and Mrs. Princess Mawa, otherwise known as Clive Scroggle of Scranton, Ohio. These people should all burn for eternity, but no one seems to be able to find them.

The Neutrality Layer, also known as the Layer of Self-interest, comes next (let me hear you say, "Monopoly if ever I saw one!") and houses those otherwise known as the telcos. The telcos whine endlessly about how it’s their party and they’ll make us cry if they want to, but they know they need to grease a lot more palms before they get their evil way.

Of course, the telcos all know they are sinners and what they do is wrong, but, driven by the demon Outrageous Profit, they cannot help themselves. They are damned to spend all eternity (that’s roughly a financial quarter) buried up to their armpits in customer complaints.

The Layer of the Wrathful and Sullen is the resting place of the geeks (let me hear you say, "Apache!"). This layer is stuffed with those who drive around with bumper stickers proclaiming, "The Internet is full, please go away," who identify with Dilbert and who argue that the ‘Net must carry all traffic without preference or favor – particularly if that traffic belongs to their latest start-up.

The next layer – the Layer of the Gluttonous and the Avaricious – is the province of the venture capitalists and anyone foolish enough to have invested in Vonage’s IPO. The VCs writhe in the eternal torment of long lunches and meetings with start-ups that all pitch their ideas for a business based on social networking for hamsters (let me hear you say, "Sounds like hell to me, and I’ll have another glass of that splendid Chateau Lafitte.")

Now we come to the big-time sinners in the Layer of the Panderers and Seducers. Here you will find the pressure groups such as the Parents Television Council and the American Family Association. These outfits game the system to promote their right-wing, mainly faith-based agendas (let me hear you say, "Sneaky!"). This plays right into the interests of the denizens of the next layer.

The Layer of Politics is where we find the lackeys of the government. Every inhabitant walks continuously in circles and agrees with whatever is said to them, no matter how illogical it might be. These sinners are capable of embracing multiple competing policies simultaneously without having their heads explode. More’s the pity.

And at the center of Internet hell is what? (Let me hear you say, "Tell us, Rev!") Verily, brothers and sisters, I say unto you that at the center of Internet hell is where we are! We can only fight the good fight, spread the good word (see RFC3751, "Omniscience Protocol Requirements"), and confess our network sins.

confess our network sins,呵呵……

见到了10年没有见的同桌

今天晚上很开心,见到了初中的同桌,在见面的路上我一直在想我们都已经10年没有见面了,还能互相认出对方吗?当见到的一瞬间,我们马上就互相认出了对方,虽然都长大了很多,但是身上都还带着小时的那种感觉。

晚上聊天很开心,一起回忆了好多初中时候的生活,似乎一切都很美好。 Smile

淋雨

今天晚上骑车回家的时候下雨了,开始的时候不是很大,快到家时雨点渐渐变密,也听到了雷声。

我挺喜欢下雨的感觉,记得小时候经常在下雨的时候站在阳台看着外边的雨景,还经常把头探出窗子淋在雨里,有些时候甚至会跑下楼在院子里疯跑,当然每次这样都免不了被狠批一顿,偶尔也会因此生病感冒。

淋雨的感觉挺舒服的,尤其在雨不是很大,刚刚开始下的时候。在自行车上张开双臂,我能听到迎面扑来的风声,衣服被风拉扯着,雨点快速的扑向自己,就好像在飞一样。

这或许很危险,我想我以后也不会再去试图用类似方法体验这样的感觉,但是我真的喜欢飞起来的那一瞬间的解脱。

下棋

很久都没有下棋了,今天晚上在国内的3个兄弟简单的小聚了一下,一面聊天一面下象棋。我是不怎么会下象棋的,只是兄弟几个一起玩玩觉得很有意思。我下棋很慢,而且没有章法,只是看着大概的形态去走子,老哥下棋很快一般喜欢在气势上取得胜利,只是对于我这样的喜欢慢慢看形势跟着感觉下棋的人,他似乎没有特别多的好办法。

最终结果我和老哥下棋,在我处于绝对劣势的情况下,想办法逼平了,当然也是在悔棋很多次之后……弟弟比较惨,悔棋无数次之后仍然输了。

大家一起偶尔聚会聚会都很高兴,就好像小时候每次过节凑在一起玩一样,很开心。

看上去很美

今天决定不加班晚上早些回家。

回家后看了一部电影,王朔小说改编的“看上去很美”。我在看DVD之前没有看过这部小说,只是听别人议论过几句,对于小说的内容基本上没有概念。

电影描写的是一个小孩的幼儿园生活,而我这个小时候据说很调皮的家伙,据说只上过1.5天幼儿园,就发誓再也不去了(事实如此)。除了几个片断,对于幼儿园时的记忆基本上模糊了。在看电影时,我一面看一面试图回忆那短短的1.5天幼儿园生活以及6年的小学。我觉得在电影里我看到了好多小时候的影子——那时候我也经常不听老师的话,经常恶作剧捉弄同学,而学习又始终处在中等偏上偶尔偏下的位置上,让老师拿我没有任何的办法。Tongue out

写几个丢人或者并不算太丢人的美好回忆片断留给自己吧:

  • 幼儿园第1天午饭,几乎没吃下东西,尽管有看似好吃的丸子汤,但是仍然是全班最后一个吃完饭(或者确切的说是被老师喂完饭的);
  •  幼儿园第1天或者第2天午休时,由于是第一次在陌生环境中和一群同龄的小孩睡觉,很不老实,总和旁边刚刚认识的小伙伴说话(可惜忘记叫什么名字了,说话的内容也忘记了),被老师批评。而当我决心不说话好好睡觉的时候,由于习惯性的侧躺转向面冲旁边的小伙伴,被老师误认为又要说话,被打了屁股。Embarassed 很清晰的记的那时候的幼儿园是偶尔有体罚的,而这是我记忆中第一次被误解误罚,呵呵。早就不记得那老师是谁了,也不知道他/她是否还健在,如果还在的话他/她还会记得这件小事吗?
  • 小学时每天写完了作业就在楼下带着一大群小男孩小女孩(我和所有人都合得来,大家都喜欢和我一起玩,那时候似乎是孩子里的小头头Cool)四处疯跑,爬假山、翻墙、爬到楼顶往下丢小石头(现在想起来满危险的,呵呵Tongue out
  • 上小学时欺负同桌的mm,把她的铅笔盒丢进了水桶里,那似乎是我第一次把女孩子气哭,不过在她哭了之后我意识到自己错了,向她道歉,而她也似乎没有把我的坏事告老师。后来她又成了我的高中和大学同学,至今仍然是好朋友,不过不知道为什么我一直都没再问过她铅笔盒的事情,估计她已忘记了吧penguin…. 其实小时候比现在坏多了,腿上经常是青一块紫一块,那是和一群小男孩们玩打仗游戏摔的;两只胳膊总有紫印,这是因为恶作剧欺负同班的小女孩被掐的,呵呵……现在想起来那时候真是有意思。
  • 小学5年级还是6年级的时候,参加了自然小组,每天记录学校气象箱里的温度,我还记得那个箱子的高度应该是1.5米,外边是白色的百叶窗。在自然小组里,我第一次做了化学实验(似乎是高锰酸钾制氧气),第一次做了一个小电路板(红黄绿三色的发光二极管可以轮流闪亮),第一次做了一个小太阳能灶(这个似乎不太成功,从来都没加热过什么东西Embarassed)…… 现在想起来也许就是这些所谓的“第一次”渐渐的对我产生了影响,并且最终引导我选择了现在的职业。
  • …… 太多了,太多的回忆,我真想把他们都写下来,留给未来的自己。

晚上回家的时候,楼下小卖部老板的一个很小的小孩子缠着我非要想骑我的山地车,我把他抱上车坐,扶着他推着车走了一小段,小孩子很高兴的样子,我看到他笑的很开心,我也很开心Smile
