似乎还有点中毒症状。。。上一个网站就看它的源代码。。。
哎,搞一个自己梦想的网站真的非一朝一夕阿~~
好,就此收住,先努力学习两个月!

再仔细的观察发现打普通电话一分钟美元是0.021,澳元是0.027,两者相比是0.77777,而skype提供的澳元兑美元汇率是0.79032。这样还是用美元帐号性价比更高!呵呵 其它币种不知是何情况,有空的人可以研究下。但是如果按现在的澳元兑美元的汇率(0.7600左右)来说,又是澳元账号合算。所以。。。看情况办喽~
哎8毛美元哦。。。

咳 所谓鱼与熊掌不可兼得。表现在相机上便是,性能与体积的矛盾(呵呵好像这是普遍矛盾嘛)。一个成像超好,功能超强,体积超小的相机,估计是有相机和没相机人共同的追求吧。呵呵呵呵 但为什么做相机的厂子不弄点这样的相机来满足市场需求咧~~为了搞清楚这个原因,还得画画中学物理里的凸透镜成像光路图。按目前的情况来看,更细腻的照片,需要更大的像素;更大的像素,需要面积更大的感光元件;更大面积的感光元件,需焦距更长的镜头;更长焦距的镜头,需要更大的光圈,需要更长更粗的镜筒。呵呵问题就这么简单,理想的说只要缩小感光元件到理论极限又不影响单像素的信噪比和感光量的话,那么完美相机就会诞生。
但是有一个重要因素限制感光元件的瘦身,就是可见光波长。民用相机显然拍摄的是可见波长段的光,也就是大约380nm-780nm的波段。这样我们的单个感光元件单元的长宽便不能低于最长波长780nm(尽管目前最顶级的光学显微镜的极限分辨率为200nm)。但事实上我们为保证低噪点,以及一些布线需要,还应加大单个感光元件单元间的距离。以1000nm的边长计算的话,也只能使之缩到大约目前的CCD(八百万的1/2.5英寸CCD)的单个感光元件单元的边长的一半。呵呵但是,如果真能缩小这么一半,那也是一大革命阿!这样同样是八百万像素的机器的镜头便能缩短一半!(当然这还不考虑使用新型大折射率材料的镜头)哎 yy以上纯属yy阿,搞相机的工程师肯定清楚这一点,另外还有很多改进可以提高相机性能,比如对焦速度,图形处理芯片,取景器分辨率等等呵呵~~所以俺要继续耐心等等阿~~说不定再过十年,达到理论极限的牛b相机就上市了。
忽然又发现时间过得好快,俺的DC(KM A200)居然发布都快近两年了,而在我手中的历史居然也有十六个月了 哎。。。事过境迁,人非昔人,物非昔物。。。不觉间,一切都在不觉间阿

My first impression is it is so crowed. It is the most crowded place I’ve ever seen in Australia! At least 40,000 people are appearing in the RNA showgrounds this day! In some shopping pavilions, it’s almost impossible to move quicker than a tortoise…
The second impressoin is the showground is so big. We spent around 4 hours on walking and watching in the showground, however, our path only covered about 30% of the exhibitions…Um you can find almost everything selling in the Australia market is exhibiting here including cars, computers, tools, toys, clothes, animals, games, food and etc….everything
The third one is it is a great chance for children to get close to the animals. Hundreds of animals are showed including pig, cow, camel, sheep, horse, bird, duck, cock, fish and so on, which all have the economic value. People can go very close to these animals and even touch them. Hehe that’s really interesting.
The fourth thing is that there are a lot of performances free on show, especially the horse riding and the firework! haha i feel i have loved the horse riding now~~the horses are so tall~look very cool!
The last but not the least one is that so many things the hosts can gain from the shows. To sum up the entry ticket ($15 for student concession), the consumption, the parking fees and the advertisement, they can earn at least two million dollars per day.
Hehe, all in all, EKKA is worth to go, both for the original residents and the visitors. More information about it can be found here.

另外预先庆祝一下小日本投降61周年。希望sb小泉明儿放明智点,别TM在它们的国厕里BM,搞得全球都被污染!招致全日本被剃平!
恩~继续剃衣服上的毛球。。。
