08:51 最烦Web2.0:营销趋势2009 » laolu's blog: Blog

Anderson Analytics的第二次年度营销趋势调查(第一次的营销趋势2008报告见这里),MarketingCharts以“Top Marketing Trends for 2009: Execs ‘Sick’ of Web 2.0”做了报道:在今年的调查中,经济问题是个重要角色,因为更多的营销者表达了对经济衰退会影响优先考虑的担忧。一半的营销经理相信2009年营销预算将会削减,但56%表示人员配置计划将保持原状或有增加。

五大营销趋势

  • #1 洞察和创新是关键(#1. Insight and Innovation Key
    约72%的受访者表示,创新努力将保持原状或增加,而39%的人说,营销研究将会在09年增加。这是一个重要的结果,大多数营销专家赞同在经济衰退期间,创新和发挥洞察绝对必要,Anderson Analytics表示。
  • #2 用户排名首位(Customers at Top of List)
    基本的用户满意和用户保持,依然是营销者最关心的两个概念,其后是营销投资回报、品牌忠诚和市场细分。所有这些,代表着对营销核心根本的重新回归,Anderson Analytics表示。
  • #3 绿色营销和全球变暖失去重视(Green Marketing and Global Warming Lose Importance)
    全球变暖问题在重视上下降最多(跌了14位),绿色营销也下降了5%。
  • #4 营销者“厌倦”Web2.0(Marketers “Sick” of Web 2.0)
    较之去年的调查,有两倍的营销人员“厌倦”听到Web2.0及其相关词语,如博客、社会化媒体等。

    但是,营销人员也承认他们对此了解不够。November 2008 MENG social media study调查表明,67%的营销经理认为,他们自己在利用社会化媒体进行营销时,还是初学者。
  • #5 最大的机会在中国和婴儿潮(Most Opportunity in China and among Boomers)
    在营销人员的国际责任方面,中国排名第一,是最大的机会区域(52%),而印度第二,远远落后,得票17%。
    在用户定位方面的最好机会,营销经理仍然觉得婴儿潮最有希望。

 

02:04 An Unorthodox Approach to Database Design : The Coming of the Shard » High Scalability - Building bigger, faster, more reliable websites.

Update 2: Mr. Moore gets to punt on sharding by Alan Rimm-Kaufman of 37signals. Insightful article on design tradeoffs and the evils of premature optimization. With more memory, more CPU, and new tech like SSD, problems can be avoided before more exotic architectures like sharding are needed. Add features not infrastructure.
Update: Dan Pritchett shares some excellent Sharding Lessons: Size Your Shards, Use Math on Shard Counts, Carefully Consider the Spread, Plan for Exceeding Your Shards

Once upon a time we scaled databases by buying ever bigger, faster, and more expensive machines. While this arrangement is great for big iron profit margins, it doesn't work so well for the bank accounts of our heroic system builders who need to scale well past what they can afford to spend on giant database servers. In a extraordinary two article series, Dathan Pattishall, explains his motivation for a revolutionary new database architecture--sharding--that he began thinking about even before he worked at Friendster, and fully implemented at Flickr. Flickr now handles more than 1 billion transactions per day, responding in less then a few seconds and can scale linearly at a low cost.

What is sharding and how has it come to be the answer to large website scaling problems?
