发帖数: 248 | 1 icebreaker， 你好，谢谢你的评论。
首先，无限上网是真实的，（撒谎是无法在美国做business的,特别是我个人觉得蒙咱
自己同胞太有失人品了） 但正如我在帖子里说明的, 对于29美元的计划， 只有前250M
是4G速度。其他为3G。这是乐卡通（lycamobile)本地区的销售代表亲自跟我讲的。因
为T-mobile只提供3G和4G.
其次，3G和4G 区别在哪呢？
我简单解释一下：
3G 是第三代移动通信标准。主要速率是400Kbps to more than ten times that.
”a minimum data rate of 2 Mbit/s for stationary or walking users, and 384
kbit/s in a moving vehicle.“ 它本身也是支持video data 通信的，但比4G慢。
4G 是第四代移动通信标准。peak 速度是100M/s. 是多媒体用户的天堂 ：D
但是，由于我们每天绝大多数是在家或公司用wifi进行复杂多媒体大数据量的使用。因
此250M 4G 应该够用。除非你不断要在路途中看电影。... 阅读全帖 |

Windows Explorer or Windows Live Photo Gallery, you had to go to your camera

·方舟子·
教育部原司长、中南大学现校长、中国工程院院士张尧学领衔的“透明计算”
课题获得国家自然科学一等奖，舆论大哗。多名IT专业人士在网上一面倒地揭露
这个课题低劣、造假、骗人的实质，这些揭露文章发表在科学网、知乎、新浪博
客等处，随后即被删除得干干净净。财新网在1月17日发了一篇报道《“透明计
算”获大奖引发诸多争议》，随后也被删除。对这些批评、揭露，张尧学没有给
出任何回应，而这些试图压制批评的删帖行为，不知是张尧学公关的结果，还是
政府部门为遮羞采取的行动。不管怎样，对学术争议只能以删帖来回应，其实质
如何，已昭然若揭了。
我不是IT专业人士，不想从学术的角度来评价张尧学的成果。我想从别的角
度，让公众了解一个被IT专业人士一致评为低劣、造假的课题何以能够获得国家
自然科学一等奖。
我们先来看看张尧学的简历：
1976年10月至1978年10月，在湖南澧县余家台水电站工作，测绘员；

Apple is reportedly holding back on the release of new MacBook Air notebooks
powered by Intel's Sandy Bridge chips and other products until Mac OS X
Lion is ready for prime time, according to AppleInsider.
The company is also prepared to wait on releasing new editions of the iPhone
and iPod Touch until iOS 5.0 with bundled in iCloud service is finalized,
the site reported Thursday. The iPhone 5 is expected to be released in the

4s by zooming in and comparing the shadows? You are being incoherent man. I
was looking at the whole picture and pointing out that where the s95 gains
in shadows, it loses in highlights, suggesting an overall dynamic range that
's not significantly wider than the 4s'.
If you don't agree that the best camera is the one that's with you, are you
suggesting the opposite?

发帖数: 953 | 40 觉得你拿S95和iPhone4S比不公平，毕竟那是接近单反的卡片机。我觉得你quote的这一
段更说明iPhone4S在non-optimal的状况下比70 - 80刀的卡片机还差了很多。
“I moved the color test chart to various areas in the lab trying to get the
phone to shoot at a higher ISO. I was able to push it to ISO 640, where
noise crossed the 4 percent mark，which would be considered downright awful
in a point-and-shoot. The Lumix S3 records 1.2 percent noise at ISO 800 and
hits the 1.5 percent mark at ISO 1600.”

发帖数: 681 | 46 Ok, let me try and explain again why you shouldn't ignore the clouds - the
4s and s95 pictures differ mostly in overall exposure. The 4s pic is darker
and thus captures more details in the clouds, and the s95 pic is brighter
and unsurprisingly reveals more in the shadows. It appears that the person
who took the pictures didn't control for overall exposure. If the 4s pic had
been exposed for the shadows, it would have been brighter. The cloud
highlights would be lost a bit, just like the s95 - we... 阅读全帖 |

发帖数: 681 | 47 well, as a "high end" compact that retails for $300+, s95 doesn't even have
auto focus while in movie mode. As far as I know, 4s does. Does it mean 4s
beats s95? haha |

发帖数: 681 | 49 That's why I don't like them. Their movie mode is just useless to me - no
matter how sharp the lenses are, or how low the noise is, if the movie frame
keeps drifting out of focus, it's useless. |
