The paper

leave a comment »

The paper "Interactive Ranking of Skylines Using Machine Learning Techniques" (co-authors: Eyke Hüllermeier, Bernhard Seeger, Ilya Vladimirskiy) has accepted by IWA-KDML2007.

"Poor" thing: I will be "forced" to present a poster on that paper in Halle on Sep 25.

"Good" thing: There is supposed to be a 3-day-vacation with free lunch, coffee break and fancy hotel room.

"Weird" thing: Prof. Nürnberger and Prof. Spiliopoulou from Uni Magdeburg might be there as well to present their work. The former will be committee member of my thesis defense -.-

New keyboards from Apple (by Darren Murph)

leave a comment »


The rumored pictures seemed plausible enough, and now Apple
has confirmed the hopes / fears of typists the world over: there’s a
new desktop keyboard (er, two actually) in town. The new keyboards (one
larger wired USB 2.0 edition with two USB 2.0 ports, one smaller
Bluetooth 2.0 flavor) are crafted from anodized aluminum, and include
dedicated keys for screen dimmer / brighter, expose, media controls,
volume controls, and eject for optical drive. Clearly, they’re making
an obvious play to capture that good will the MacBook has garnered for its interesting spacing and flat keys, but it remains to be seen if such a laptop-ish keyboard
can keep up with the more tactile big boys on the desktop frontier. But
hey, with that much sexy, we’re willing to find out. Click on for a few
more glimpses, and just in case you were wondering, it’s $49 for the
tethered one, or $79 to go cordless.

补一下:这款键盘已随Apple最新款iMac一同发售。下面是这款iMac与Dell XPS的比较图:

NASA制成迄今为止最精细的地球影像

leave a comment »

  美国航空航天局(NASA)最近制成迄今为止最精细的地球影像。我们所居住的蓝色星球上每一寸土地都被摄入其中,堪称迄今最完整详尽的地球“肖像”。

  影像的图片采集由安装在“特拉”卫星上的“中分辨率成像光谱仪”(Moderate Resolution Imaging
Spectroradiomete)完成。它位于距离地球700公里的高空,每两天覆盖全球一次,具有36个可见光-红外线的光谱
波段,空间分辨率为250米~1000米。图片采集完成之后,再通过数月的数据合成形成完整的地球影像。

  这份地球影像能够比较全面的展示当前地球的地理状况,给观测地球的人们全新的视角。地球的陆地、海洋、冰川和云层都被摄入其中。相关对地球的观测计划将历时15年,有关照片将不断从太空传回地球。NASA计划不定期发布合成的地球影像资料,帮助科学家研究地球地理变化。

德国手机在瑞士

leave a comment »

  以上是几大德国电信公司Prepaid卡在瑞士的漫游价格。如果经常使用电话,可以考虑选择瑞士当地的Prepaid卡。瑞士的Prepaid卡在使用上与德国基本一致。用户不受合同的约束,在购卡时随卡将得到一个新的手机号码,遵守先冲值再通话的原则。因为不是漫游,所以用户起码不需要为接收电话而付费了。如果自己拨打电话,在Call-by-Call模式(即一般模式)下,大多瑞士网络提供商的通话价格在16cent/min以下。

  上表列举了几个比较超值的Prepaid卡供应商及相关信息。当然也不拘于这几个选择,因地制宜才是选购时的最佳策略。
