PRP结束了

PRP在今天的答辩后结束了,杨明老师发邮件来恭喜我们通过了答辩,也算是对整个项目的一种安慰。说实话,总的来说这个项目做的还是挺失败的,没有达到预期的设想,这其中有各方面的原因,对于选择VB作为开发工具,我至今还表示质疑,事实上从去年11月做出雏形后到现在,整个程序就几乎处在停滞不前的状态,这其中很大的原因在于VB 6.0不支持面向对象,导致整个程序向深一步发展相当困难。当初的初衷是好的,只可惜事与愿违。当然,失败的原因还在于我今天上台陈述时的重点有所偏差,由于从前几组的答辩情况看,评审老师的喜好与我事先的构想有所出入,导致临时调整了一下演讲的思路重点,结果导致了一定程度的混乱,还是经验不足的缘故,希望以后还有机会能够锻炼一下。稍感欣慰的是上台做presentation的时候重的来说发挥的还是挺松弛的,除了少数部分有些许卡壳。原本以为会很紧张的,现在看来在实际的场面下自己还是会不自觉地调整好心态。

带着些许可惜结束了此次PRP,不仅因为最终成果的不理想,更主要的是感觉没学到什么东西,纯粹是用自己的编程能力搞出个软件,这也许才是最大的遗憾。不过不管怎么说,在整个项目期间无论是杨明老师还是孙一飞学长都给予了我们很多的指导,今晚一飞还打电话安慰了我们一下,感动ing。。。人生有得有失,才显得弥足珍贵,希望以后能有机会弥补这次的教训,期待下一次的挑战。

基于VB多智能车辆合流分流仿真平台

辛苦了一个下午,把“基于VB多智能车辆合流分流仿真平台”基本功能完成了,不过程序还比较粗糙,架构也有待于进一步优化,而道路的文件载入功能由于我们小组还未进行最后的整合因此也没有考虑。还是原来的观点,用Basic简单是简单,但无论是架构还是扩展性,仍然有一定的不足。

Shanghai ranks 20th!?

Couple months ago, I read a piece of news on newspaper which shows that Beijing ranks 14th while Shanghai 20th in the world’s living cost ranking. To be honest, I was really shocked at this ranking cause I could not understand how it could turn out. In the list, there’s a familiar city caught my eye, which is Seoul, where I still was a few days ago, ranking 2nd. I could admit that the price there is high, but it’s still not higher than many western cities and some Japanese cities like Tokyo as well. And if Shanghai really ranks 20th, I have no idea that how many natives could survive in this city.

It doesn’t mean that Chinese people are all poor. On the contrary, I do think that we Chinese lead a good life these days. In my opinion, the standard judging whether people are rich or poor should stand on the life quality they own. In this term, I found Shanghai nothing different from Seoul since people in Shanghai could have the same quality of life compared to those in Seoul. To some extent, Chinese people nowadays are not poor at all.

But one problem is that when we are abroad, we will feel that we are “poor” cause the price level in foreign cities is usually higher than we could afford. We come to realize that when our money is exchanged to that foreign local money, the same value could not afford the same amount of stuffs as they are in China. In other words, our money becomes less after exchanged. According to the “Principle of Economics” written by Markiw, the exchange rate should satisfy that money remains its same value no matter how many times it is exchanged. The idea may be a little ideal, but it points out the key. I have to say that the exchange rate of RMB is too low which makes us “poor” when we are abroad. One strange issue is that some famous foreign products’ prices are almost the same at their countries as well as in China, which may conflict the idea I mentioned above. But I think this might because the price in China does depend on the exchange rate and the original price in its home countries. So if we change the exchange rate, the price in China will relatively change higher or lower to adapt, therefore the price is always the same around the world. I know that low exchange rate might stimulate the foreign investment so that it could benefit our economics a lot. But if this situation still doesn’t change, we Chinese people will always be “poor” if we go to foreign countries.

项目结束,开始休假 ^-^

4个星期8学分的暑期课程,随着今天我们小组presentation的顺利完成而曲终人散,等待着我们的将是一个星期的休假^-^,之后便是开学-,-#

回首这一个月,感觉自己真的学到了许多,经过这次的锻炼,算是踏上了CS的门槛了吧。从以前编的“自娱自乐”的程序终于进升到了可以供人使用的工具,还是很有成就感的。

当然不得不说我们这次选题比较失败,选了一个“网上书店”项目,结果惊讶地发现前13组presentation中竟然有至少7组是同样的课题,真是泛滥成灾啊。。。虽然形势不太有利,不过我们还是在长河落日同学的冷静精彩的描述中获得了老师、助教的好感(难道是我yy?呵呵~~)尽管如此,还是要说,选题太失败了,我还是原来的意见:应该做bbs,个人感觉实现起来会比网上书店来得容易,而且反而来得有心意。

可以说昨天的presentation真是大不一般。见识了cs的大牛csk同学的“EZ UML”软件,不得不说真的是大牛啊,牛的不行了,牛得我们都自卑了,和他的做的软件比起来,真的感觉我们做的只是玩具-,-# 真的是太牛了,说“牛”一千遍也不过分,我对他的崇拜之情犹如滔滔江水。。。(以下省去赞美之辞1000字)。当第三组的他抛出这个惊人的成果时,还未开始的我们快要崩溃了。。。幸好牛人没有扎堆在我们前面讲,不然真的不活了。。。

Anyway,忙碌的一个月就这样结束了,一下子空下来还真是有点不习惯,呵呵。好好休息一个星期,然后迎接新的学期!
