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

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……

敬业

昨天深夜被告知可以继续追加必要的预算以便完成今年的建设目标。今天早上不到8点,给某公司的sales发了个消息,请她帮忙找资源写出相应的规划。大约半分钟后就接到了那个sales的电话,20分钟后接到了相应的工程师的电话询问具体需求……我告知对方,我下午才能到家看到方案,于是方案和报价在下午1点之前就送到了我的信箱内……

我有些感慨他们工作的高效,这样的工作态度和风格是我佩服和尊重的,也是对我这样已经在学校工作了几年的人的一种警示,我现在仍然能做到这样的高效响应吗?

又开始讲课了

今天上午9点至11点30分,和准备参加网络大赛的8位同学一起复习了CCNA第一学期OSI模型和以太网技术的内容。这次讲课我作了全程的屏幕录像+声音记录。我想这留下来或许会是有价值的一份资料吧……

btw,按照delphij的话说,我昨天贴的照片好像是鬼片里的一样……其实我只是觉得这张照片是我毕业最好的留念了…… 毕竟这里只是写给自己的一些文字,留着吓唬吓唬未来的自己吧,呵呵。

周3开会的通常过程

每周3下午2点开会……通常的过程如下: 

  1. 领导发言指出本次会议的要点,顺便传达一下最近的文件和更大的领导的精神(通常历时40-90分钟不等);
  2. 在领导发言快结束的时候我通常由于忍受不了长时间单一姿势的听同样内容的话,会溜出会议室5-10分钟;
  3. 涉及到的所谓的主任们依次发言,说说自己的工作要怎么做,其间领导会多次插话,并征求其他的几位所谓的主任的意见;
  4. 由于对于某些事情可能会有不同意见,几个人开始争论,当然只是单纯的针对事情的争论,而不是针对人,呵呵。偶尔我心情好或者心情不好的时候也会参与这样的争论,当然如果事情涉及到我,我不论心情好还是不好都会去表达我的想法;
  5. 某些事情陷入僵局,会出现一些人开始左右泼水和泥……偶尔我闲得实在是无聊的时候也往天花板上丢几个水球之类的……
  6. 开始犯困,再次溜出会议室,10-30分钟不等后返回,当然有些时候想返回的时候会议已经结束了;
  7. 开始有其他的人和我一样一个一个溜出会议室……
  8. 会议室只剩下了领导和几个快睡着的和议题毫无关系的人,或者只剩下1-2个还在和领导争论的人。
  9. 不知道什么时候就散会了……

呵呵,这就是我不喜欢参加的所谓的会议。我觉得太多这样低效的会议只会在降低生产力的同时影响工作情绪。

实验环境就绪

今天晚上和liyinghao一起整理了好了给每人一套的参赛准备环境。俩从晚饭后一直忙到快10点,忙了一晚上但是心情很好。做这些事情的时候让我感到对未来的希望,让我感觉这是我在为可以控制的未来努力奋斗,这是我真正想做的事情。

打扫了实验室·准备网络比赛

今天下午和PP一起打扫了新得到的实验室。屋子好像好几个月都没有人用了,所有的桌子都落满了土,我们用洗手液擦了半天桌子,好不容易让桌子见到了一点点正常的颜色,不过地面还都没有打扫。

还有1周就要结束网络比赛的报名了,似乎大多数强校都没有提交报名表格呢,大家都在等待吗?呵呵……今年的设备可以支持到每个人一组设备进行调试,而且也有专门的环境来练习了。我想如果大家能够团结一致去努力的话,一定能拿到比去年更好的名次。我知道我们是有相应的实力的。Cool

Cisco 7200 Simulator

几天前在南京开会的时候听到某学校的老师讲有一个小软件可以很好的模拟Cisco的7200系列路由器:dynamips,今天看了看代码,这个软件是使用Python写的。

大概3年前就曾经想学习一下Python,不过后来一直都没有学习的动力,再加上杂事比较多,最终也就拖延过去了。经过几个月的C# + Managed Direct3D开发,现在是该换换脑子的时候了。至少这几个月的开发,证明我还是具备在一定时间内掌握一门全新技术的能力。有一种想通读这个模拟器代码的欲望,好好分析分析也许能提高不少技术。
