  • Watermelons are not just a favorite summer treat, - according to new research by the US Department of Agriculture, they may soon fuel our cars. Research reveals that watermelon juice has a relatively high concentration of directly fermentable sugars, which may be a valuable source for biofuel due to the ease with which they can be fermented into ethanol. But don’t worry about your favorite corn field being plowed under to make way for a new cash crop - researchers say there are enough wasted watermelons out there to use as biofuel feedstock.

  • Ever increasing oil prices, environmental concerns and the insecurity of oil supply force the need to look for alternatives to fossil fuels. This is not only the case for transportation fuels, but also for raw materials for the chemical industry. Most polymers still depend on fossil resources for their building blocks. In the case of nitrogen containing molecules, production usually involves reactions of molecules such as propylene with ammonia in very energy-intensive processes.

  • EL PASO -- A proposed solar power plant in Santa Teresa, which would supply electricity to El Paso Electric, isn't the only solar development going on in this area.

    Applications to use federal land for one solar project in the Afton, N.M., area, just south of Las Cruces, and two in the Lordsburg, N.M., area, about 140 miles west of El Paso, have been filed with the U.S. Bureau of Land Management.

    • 还有马上要推出的我认为会成为中国手机的标配就是蓝牙分享,而且我们两个人的手机不一样也没有关系。你只要按一个键分享给周围的人,周围都会安装GO
    • 因为手机蓝牙传输这些文件的时候是非常方便的,尤其是你向别人推荐的时候,我有这个,你用一下吗?他说你装给我,如果是上网的话,一下子浪费我的流量,是不是收费?但是你装上以后就可以感受到

    • 第一个是首先我们的研发人员,我们的产品经理,我们的美工都要把自己变成又是最白痴的用户,又是最专业的用户,这两者是融为一体的一个人。我跟你讲,我们的CEO,我们的CEO是我们公司最大的产品经理了,有人问他,为什么你每次做这个东西的时候,你就能够感觉到用户的需要呢?他说因为也许只有我可以每天超过16个小时在按手机,他太太给我抱怨一件事情,就是每天晚上他都睡着了,把他的手指掰开把他的手机拿回去他才能睡觉,他不断的在按手机,这当然是我们CEO做得非常好,我们的人员也是这样的,连我们财务的人员都是我们的专业用户,这不是我们吹牛,我的没有开玩笑,我们财务部的同事都是非常熟练的手机玩家。你要非常广泛的手机用户的需求,3G用户毕竟是在无线的用户里边,我们有这么多的用户,我们能够不断的搜集用户的需求,我们有这样的一个便利,我们的各方面也会综合意见,我们经常吏部都会经常的搜集他们的用户意见。因为用户可能一千个人有一千个需要,你怎么把这些需要总结归纳起来,先满足哪些,其次总结哪些,我觉得这是优秀的产品经理的一个能力所在了。

    • 张向东:在互联网上,我始终认为,一个成功的互联网公司要真正的去满足用户的需求的时候,其实用户是很难描绘出自己的东西。就像腾讯网,我就非常钦佩腾讯网这一点,我知道腾讯的创始人马化腾,我们也见过面,聊过天,我知道他的一个故事是什么呢?他曾经在做一个邮件的一个产品的时候,他说,当用户点回复的时候,他的鼠标、光标应该直接挪到了邮件的正文的部分,当他选择转发这个邮件的时候,他的光标应该在哪里?他的光标应该在地址栏,收件人的那个位置,是用户给你描绘不到这一点的,但是马化腾做到了这一点。

    • 我给大家拿一个非常漂亮的东西给大家看,这是亚马逊的Kindle。这是另外一个产品,在另外一个大陆之上,在欧美大陆之上,这个产品正在受到很多人的欢迎,亚马逊网站是在中国被忽视的一个公司,没有留意到亚马逊公司其实是做得最好公司之一,它的股价也很好,公司的营业状况也很好,在物流方面做得也非常棒,是我非常崇敬的一位公司,Kindle推出来的时候它跟GO有什么关系呢?它是理解阅读习惯的一个,它是真正指导人们从纸媒转移到一个移动终端上看书的期望是什么,这个期望不是用户描绘出来的,而是公司的产品做出来的。当然这个东西我觉得中国的可能难度会大,因为欧美比中国现在其实是更适合阅读的一个民族,但是中国现在在阅读方面体验没有那么高。他的成功有很多的细节。GO这个产品我们是满足用户的想象。

    • 我有的时候说QQ好棒啊,如果把今天的QQ在十年前推出的时候,用户肯定没有人用的。这就是互联网产品的一个特点,你要用时间让用户去检验它,然后不断的调整

  • While I disagree with a lot of this, I recommend this essay anyway, as food for thought.

    • While I disagree with a lot of this, I recommend this essay anyway, as food for thought. - By David Corking
    • How many of our most joyful memories have been created in front of a screen?
    • Communicating at great haste hones our utterances down to instincts and impulses that until now have been held back or channeled more carefully.
      • But most of us can speak faster than we can type or text, and no-one complained that conversation makes our brains work too fast. - By David Corking
    • Our cafes, post offices, parks, cinemas, town centers, main streets and commu­nity meeting halls have suffered as a result of this development.
      • Really? How many people met strangers in such places? - By David Corking
    • The difference between typing an email and writing a letter or memo out by hand is akin to walking on concrete versus stroll­ing on grass.
    • A butcher can tell you which cuts of meat are the freshest; an online grocer may not. That same butcher, if he is good, might not just remember your preferences—which an online retailer can do frighteningly well—but ask you how your mother has been doing, whether you caught the latest football game. These interactions remind us that we are more than con­sumers; they remind us that we are part of the world in a way no amount of online shopping ever will.
      • This is right on the money - a visit to a local farm shop is a wonderful experience. - By David Corking
    • If we spend our eve­ning online trading short messages over Facebook with friends thousands of miles away rather than going to our local pub or park with a friend, we are effectively withdrawing from the peo­ple we could turn to for solace, humor and friendship, not to mention the places we could go to do this. We trade the com­plicated reality of friendship for its vacuum-packed idea.
      • It might be just the way this essay was abridged for the paper, but I cannot see whether the author wants us to spend all evening writing a longhand letter to a distant friend, or ignore them altogether to spend time with a local friend. - By David Corking

    • 据国外媒体报道,美国投资公司RBC资本市场分析师麦克·阿布拉姆斯基(Mike Abramsky)日前表示,到2011年底,全球智能手机销量将超越PC销量。



        阿布拉姆斯基预计,2011年底,全球智能手机年出货量将接近4亿部,略高于PC销量。到2012年,全球智能手机销量将达到5.04亿部。



        这也正是智能手机市场竞争异常激烈的原因所在,当前,苹果、戴尔和微软等科技公司均希望在智能手机市场占有一席之地。戴尔本周刚刚证实,正在为中国移动开发一款智能手机Mini 3i

    • 即使是分众结构做的最好的豆瓣,据统计,其热门小组也只占到了所有小组1%不到,但是话题数和访问量却占了超过60%以上。所以,即使是“长尾”,这个尾巴比起身子和头部仍然是比较小的
    • 追述社区发展历史,真正意义上成功的群组只有一个——百度贴吧
    • 百度贴吧的成功不在于贴吧本身的产品结构,而是在于它并非独立的社区产品,它是和百度的强大搜索引导密切相关的。因为巨大的搜索导入,这个互联网最大的应用成为贴吧能够成功的最大核心动力
    • 一般来说,对于新论坛或者新群组,每日新帖更新少于5条,跟帖少于10条,总帖子页数少于3页以上,发帖人数少于20人,那么这类小组就比较难以形成持续的活跃。豆瓣相对来说,有一点例外,这基于两方面,一方面,豆瓣上的很多好友的建立是基于较强的信任关系;另外一方面,豆瓣以社区文化作为其非常重要的一个聚合因素,而这类社区文化则更多的是以“共同的话题内容”作为聚合的点,所以小众群体比较容易形成针对共同感兴趣的话题进行交互(事实上,豆瓣的用户本身的UGC贡献度也比一般社区高)
  • tags: SNS, group, features

    • SNS的主要信息传播渠道是FEED(好友动态),大部分用户只通过这一主渠道来消费信息。用户能够对信息进行选择和调整只有一个途径,就是控制自己好友的品质,而这一点,基本上只有少数高端用户才会做,并且使用成本并不低。从这个角度我们就可以看出,对于以话题来聚合人群的群组,在SNS社区架构下,本身就已经处于边缘化的位置。它只占据了SNS中的二级渠道,所谓二级渠道,就是用户并不能在SNS网站的首要渠道(FEED)里面集中地看到,而只能通过好友FEED中的话题内容这个相对零散的入口来参与。而这种零散的入口结构,本身就不符合对于“话题消费”的社区用户的需求
    • 总结一下:SNS社区里群组难以形成热度的原因:



      1、没有巨大的搜索入口作为支撑



      2、SNS主体信息引导渠道是基于人脉传播,而非“共同话题”,话题消费在SNS里是二级渠道。



      3、群组由于曝光渠道的少,所以内容的数和量难以达到一个引发爆发响应的临界点。



      4、SNS的人际关系大多是弱关系,所以很难形成基于关系的热回应。

    • Twitter联合创始人比兹·斯通(Biz Stone)周四表示,添加地理位置服务可以增加信息的价值,令信息更加有用,更加有趣
    • Twitter地理位置服务功能将首向通过应用程序接口(API),面对应用程序开发者发布,以使其他应用程序可以同样提供该功用。斯通表示,Twitter最终将在其网站及移动版本上推出该服务。
    • Twitter最新技术将在用户发送信息时,明确其所处位置,但该功能是可选服务,用户可以决定在哪条Twitter信息中加入其地理位置数据。

  • tags: screenr, twitter

    • 今天才刚刚推出的Screenr可以让你进行长达5分钟的屏幕录制工作,它因它的易用性而独具一格。你只需使用你的Twitter 帐号来登录,然后点击”录制“按钮就行了
    • Screenr是运行在浏览器里面的,因此你无需安装任何软件。一旦你完成了录制,你可以通过这款应用程序立即将你的视频发送给你Twitter上的关注者们。
    • 将录制的视频发送到Twitter这项功能是可选择,不过多数用户显然是冲着这项功能才来使用Screenr的。与Twitter的整合也相当深入,因为你可以直接在这款应用程序中锐推(re-tweet)屏幕录制视频,当你留言时,你也可以选择把留言作为@回复来发送到作者的Twitter。
    • 一旦录制完成后,你可以在Screenr站点观看你录制的视频,或者将屏幕录制视频嵌入到一篇博客文章中去,你也可以直接将它上传到Youtube上去,或者下载桌面,然后对其做进一步编辑。Screenr上的所有视频都是默认公开的,网站不提供隐私设置。
    • 我们也要提醒一句,Screenr为iPhone提供提供一个非常友好的手机界面,因此,使用手机终端的Twitter用户也能够观看你的视频
    • 留言中有人指出,Screenjelly 跟Screenr非常相似)。所有这些工具都提供相似的功能,不过Screenr之所以突出,是因为使用它录制屏幕视频,并与好友分享的过程非常之简单

    • phone三脚架,看起来像带在手上的饰品,由Gorillapod Gorillamobile设计,售价30美金。

      有了它,你可以将你的iphone固定在桌上,跑步机上,或者自行车的把手上。这个三脚架非常

      灵活,可以随意改变它的形状。

    • 根据最近一项在老鼠和人类身上进行的研究,吃多脂肪食物几乎会立即影响短期记忆和运动表现。在此之前的其它研究暗示,长期食用高脂肪食物会引起体重增加,心脏病风险上升和认知功能下降,但新的研究显示,在短短数天内,多脂肪食物就能影响大脑和身体。
    • 为了判断高脂肪食物对短期记忆和肌肉表现的影响,研究人员首先让32只老鼠食用低脂肪食物,训练它们走迷宫。为了让老鼠依靠记忆通过迷宫,研究设置了很多陷阱。在所有老鼠掌握穿过迷宫的方法之后,研究人员让一半老鼠食用高脂肪食物,结果在4天之后,这群老鼠在穿越迷宫时便遇到了麻烦。而在跑步机上测试显示它们的运动表现下降了30%。

    • Simplify Photo的吸引力在于你无需在你的iPhone,笔记本电脑,或上网本上存贮所有这些文件,因为这些设备上的存储空间通常都是个问题。Simplify Media的桌面应用程序会将你的Mac或PC变成一台媒体服务器,你可以远程访问你的音乐和图片。Simplify Photo目前在应用软件商店中的售价是0.99美元
    • 把你的PC变成媒体服务器


      因为Simplify Medi只是将你的电脑变成一台媒体服务器,它并不会在云中存储任何数据,所以你想使用这款iPhone应用程序的话,你的电脑必须一直保持运行状态。这大概是Simplify Media系列应用程序一个最大缺点。不过,这也避免了这款应用程序可能带来的版权问题,以及公司无法承担的照片存储问题。


      如果你想访问你所有的图片,于此同时又不想占用你iPhone和iPod Touch上太多的存储空间,另外你也不想让你的机器24小时运行,并愿意支付小笔的月费,你应该关注下来Phanfare的图片应用程序(link),我们第一次对它做评测的时候就喜欢上聊这款应用程序。

    • About CoursePro

      CoursePro is an easy to use homework application for students to keep track of courses, assignments, and grades. We are excited to announce the arrival of CoursePro for Google’s Android platform. You can get CoursePro by opening the Market from your phone. If you are not viewing this page from your phone, you can see the Market here.


      With CoursePro, you can keep track of your homework assignments using a simple to-do style list that has been specifically designed for students. Define Assignment Types—such as quiz, homework, project, or lab—to keep track of your weighted grades the way your professor does. CoursePro automatically keeps a current report card, so you can see exactly what your grades are at any time. You get a full grades break down by assignment type. CoursePro even allows you to specify which Assignment Types have ‘drops’. Coursepro will then automatically drop the lowest graded assignments for that type.

    • Just found out about 3Banana today and think this is a great web-app/service. I'm currently using evernote and find it more complex to use than 3B. I'm thinking of moving all my evernote's data to 3B.



      Are there any way to do this other than copy/past each note to 3B? (not fun for 700+ notes)
  • tags: android, app, 3banana, idea

    • I use 3B on my PC and on my Android phone. I usually use the PC to add notes, and my phone to read them while on the go. Some notes contain contact information like a phone number.
    • At the moment it's quite a hassle to use such a phone number: I have to memorize it, or write it down on a piece of paper. It would be great if I could click-and-hold the number, resulting in a pop up with options. I'd suggest two of those should be "call this number" and "add number to contact". The latter should result in a screen where I can select an existing contact, or add a new unlisted contact.
  • tags: android, app, 3banana, idea

    • I'd like to be able to have a clean and tidy print view, so i can print all notes in a given category. At the moment the left side of the site always shows up, occupying a lot of space. A "Print these notes" link at the top or bottom of every page would be really helpfull.



      On a sidenote: it would be even better if there where checkboxes next to every note, so I could select only those notes I'd like to print.
    • One of the key benefits of 3B is that you can view, add and edit notes on multiple platforms, as long as you have an internet connection. Why create a fixed state document?
    • So in short: I don't think I'll use a PDF-version. To me a print view would be sufficient.
    • I'd like to be able to have a clean and tidy print view, so i can print all notes in a given category. At the moment the left side of the site always shows up, occupying a lot of space. A "Print these notes" link at the top or bottom of every page would be really helpfull.


      In other words: I'd like to print ALL notes (or the X latest ones) with a tag, like #work or #diary.
