Today we announce AdClimate, a new feature of the formidable FeedBurner ad server for blogs and RSS feeds. AdClimate gives marketers and advertisers the power to suppress their ads from being served into content they might deem questionable. By way of example, let's say you have an aversion to the word, "wingnut" and the thought of your ad for pinenuts showing up in a publisher's blog post about the history of wingnuts would be totally unacceptable (hey - who are we to judge?) AdClimate to the rescue. In addition to screening a multi-language default list of inappropriate language, advertisers can submit their own list of keywords next to which they don't want their ad to appear - wingnuts and all. AdClimate is the solution for that awkward adjacency issue that makes advertisers and media planners sink a little lower in their chairs (kind of like lumbar support, but without the foam cushion or unfashionable belt).
If there’s one thing we can say about the content produced by our 393,805 publishers, it's diverse and, some might say, unpredictable. For advertisers, having an extra layer of protection is just the lifevest they need before jumping into the deep end of all that content generated by users. And when we say deep, we’re talking about hundreds of millions of ad impressions from some of the coolest, most provocative and cutting-edge content producers on the Web today. You know who you are.
In the world of distributed media, brands need to be protected which is why the AdClimate concept has been met with very positive feedback from agency execs across the land. One such exec is Tim Hanlon, Senior Vice President, Ventures, at Denuo, the media futures arm of Publicis Groupe who had this to say, "Despite the wealth of quality user-generated content on the Web today, many marketers are still wary of promoting their brands amid the unpredictable landscape of blogs and RSS feeds. As the pioneer in feed-based syndication and advertising services, FeedBurner understands this environment better than anyone, and this advanced form of protection will be an effective measure to address marketer concerns -- ultimately enabling more ad dollars to flow into the distributed media space."
We couldn't have said it better ourselves. AdClimate allows advertisers to reach increasingly fragmented audiences as they turn to new content sources like RSS feeds and blogs, with access to hundreds of millions of new ad impressions. That's good news for ye publishers.
So, who’s afraid of blog and RSS feed advertising? No one now. Learn more about AdClimate or contact a friendly FeedBurner ad person to discuss your campaign needs.

现在在很多领域中的研究都不能避开von Neumann这个人,然而,这个人在中国大众中的普及程度估计比不上霍金、纳什。在计算机等级考试中,我们都背过,第一个发明电子计算机的人是冯诺依曼,但他在其他领域的贡献就很少为大众所知了。
他是博弈论的创始人,人工生命的理论先行者,计算机的发明人,甚至也是复杂性理论的先行者。他还有很多很多洞察是不为人知的,真的感觉他的思想太超前了。
这篇文章是wolfram (Mathematica软件的作者,A New kind of Science的创始人)写的纪念von Neumann的文章,共勉吧。
John von Neumann's 100th Birthday
Today (December 28, 2003) would have been John von Neumann's 100th birthday---if he had not died at age 54 in 1957, and that gives me an excuse today to write a little about him. (I would have liked to spend longer on this, but December 28 only lasts so long, and I have many other things to do.)
I've been interested in von Neumann for many years---not least because his work touched on some of my most favorite topics. He is mentioned in 12 separate places in my book---second in number only to Alan Turing, who appears 19 times. (See www.wolframscience.com/nks/index/names/t-z.html.)
I always feel that one can appreciate peoples' work better if one understands the people themselves better. And from talking to many people who knew him, I think I've gradually built up a decent picture of John von Neumann as a man.
He would have been fun to meet. He knew a lot, was very quick, always impressed people, and was lively, social and funny.
an impressive complete family tree compiled for about 4,000 mammal species showing how different groups, such as primates & rodents, are related & when they diverged. the so-called "Supertree" visualization is a new way of showing all the mammal species on the planet, starting with a common ancestor.
"What we did instead was use already published information from hundreds of researchers around the world. We used a new technique called supertree construction which allows us to get all the information that's out there, re-code it and re-analyse it as if it's all part of one dataset."

线性周期系统当中最重要的定理就是 Floquet 定理。这个定理的意思是一个具有周期系数的线性常微分方程可以通过约化成为一个常系数的常微分方程。考虑方程:
,其中A(t)关于t是T周期的。
首先可以证明对于方程的一个基解矩阵
,
也是方程的基解矩阵,于是存在一个常矩阵C满足
,而且C可以表示成
,B是一个常数矩阵。
令
,易知P(t)是T周期的。
下面做变量代换x=P(t)y,并将x代入原方程
即可得到
至此,就将周期系数的线性方程约化为常系数方程。
Floquet 定理具有非常重要的意义,因为它的高度概括性,使得它能应用在自然科学的很多领域,据我所知量子力学当中有这样一个结论:电子在一类周期势中运动时,其定态波函数总可以表示成一个平面波乘以适当的与势同周期的周期函数。在 Floquet 定理中正是
。此外,在传染病模型等很多领域,都可以看到 Floquet 定理。
我的本科毕业论文正是关于 Floquet 定理,我所要研究的问题就是寻找一些普遍的情况,使得在这些情况下对于实系统
可以找到实的T周期变换x=P(t)y(而这在一般情况下是不能满足的)。
在阅读下文之前,大家先看一下喜欢动物之森的100个理由这篇帖子,有一个感性认识,这样大概可以明白为何我要写它的情感化设计了。
江口勝也,任天堂《动物之森(Animal Crossing)》系列制作人在 06 年游戏开发者大会(GDC)上发表的演讲:Is That a Franchise in Your Pocket? 讲述了该系列游戏的理念:Communication。
我对 Communication 的理解是:对话、交流、分享,甚至展示……
江口勝也认为营造独特体验在于高自由度,于是提供了大量的道具、收藏要素。只要你知道“哦,原来可以这样啊”,那你就会产生一种渴望的心理。比如说,村子里的树木可以用斧头砍掉,树桩可以用铁锹挖掉,这样就可以重新种植树木。一种渴望改变村子树林布局的情感顿然而生。当你发现买家具需要钱的时候,你就去寻找赚钱的方式,比如钓鱼、卖水果或者其他。
从玩家的角度,《动物之森》的独特体验比如:
这可以说是相对其他游戏来说的,那么从游戏本身的角度,怎么体现出独特(个性化)呢?
当然《动物之森》的个性化设计不仅仅是以上说的几点。独特体验的重要性在于可以让人产生渴望并满足(无论是快乐还是恐惧,如 Konami 的《寂静岭》系列游戏)。同时独特体验也是吸引新玩家,并且保证 long-last 的秘诀。江口勝也给出的一个情感循环:
渴望 -> 满足-> 分享 -> 刺激 -> 渴望,能跑完这个循环,或许是本游戏成功的秘诀吧。
Communication 的理念决定了《动物之森》是一款社会化游戏。与动物们的交流、与其他玩家的交流是游戏的核心。
《动物之森》并非十全十美的社会,和真实世界一样。动物会离你而去,新的居民也会不断出现。当你提前发现动物有搬家迹象时,你可以好言挽留。你可以给动物们写信并附赠礼物,动物也会给你写信,也会给你送东西。冬季的时候动物还会送你衣服。当动物病了,你可以给动物买药,这样可以提高他对你的好感,当好感度最高时,动物还会给你送他的照片。
有一次我三个月没玩游戏,当我再次进入的时候,发现有一些动物已经离开了村子并且给我写信告别。路上遇到小动物,她说:天哪,我有三个月没见到你了!你都到哪儿去了呀?
借助于 DS 的 WiFi 功能,你可以参观其他玩家的村子,从其他村子带回特产水果种树。也可以打开自己村子的大门等待朋友访问,展示自己的屋子、家具、博物馆…通过 WiFi,小动物也会在不同村子间搬来搬去,你可能会在朋友的村子里发现几个月前离开的那只小猫,她还会记得你的昵称并且亲切的叫你。
论坛上有一位玩家,因为一只叫 Kiki 的小猫离去,而伤心不已。在论坛上发帖寻找 Kiki,希望可以好言相劝,让她回心转意重新搬回村子。
这就是《动物之森》的魅力!
当然游戏总是有不足的地方,比如 DS 的 WiFi 限制,玩家双方确认才能进行连接。这一点相信在 Wii Connect 24 上有所改进和突破。
一款好的游戏,可以在本能设计层次上做的非常出色,有丰富的视觉效果和声音效果,比如大部分的 PSP 游戏;也可以在行为设计层次上很优秀,比如容易上手的操作、完善的任务系统(如《怪物猎人》系列);但是最好的游戏,能够让人深入反思,即能够对自我行为进行思考。“为什么会这样?游戏的世界观是?”。反思层面与文化关系密切,但是从销量上可以看出来,《动物之森》获得了全世界大部分玩家的亲睐。
