Source favicon22:18 Google Reader的一点使用体会 » Blog on 27th Floor
近来由于网络的问题,白天只能用Google reader来看rss,对它也算有了些体会。

Google reader能导入opml,处理中文、保持Blog原有格式上也没有问题,算是个合格的Rss阅读工具。但不爽的就在它的阅读体验上。

在Bloglines里面或其他一些在线不在线的阅读器里,只要点击一个feed,就会自然设置为“已读”;但在Google这里,它试图猜测我的阅读行为,并控制我的动作。点击一个feed,它并不认为你已经读了,而是希望你在右栏再点一下,或者是滚动一下,哪怕这条贴子实际上只有三行,完全不需要滚动,而眼睛实际上也已经完成了扫描。这些它都不管,它要求你要么滚动,要么点击,否则这一条就是未读。并且据我观察,滚动的速度还不能快,点击也有一定的时间要求,并不是它显示出来一点击就行的。

设计者的原意也是好的,希望更加智能,更加准确,但由于目前技术的限制,实际的效果却比没有设计更为糟糕。如果屏幕上有个摄像头,可以看到读者眼睛的扫描目标,它可能是相当准确的,如果没有这个,而只是从设计者的角度设定用户阅读的行为,这就太过简单了。

邮件客户端也会有这么一个设计,即点击一封信件几秒后标记为“已读”,而通常这个几秒都是一个可以设置的数值,我一般都设为1,如果不能设为0的话。现在信息量这么大,读者又不是上语文课的小学生,一定要老师看着读课文几遍吗?

另外还有一点,就是如果它在读取数据时遭遇了不测,比如被reset这种情况,它会显示has no item,并且在reset起作用的那几分钟时间里对所有feed都会这样显示。这也太过自作主张,为什么不直接显示一个网络问题呢?Google遇到reset是我们都可以理解的啊。

你完全不用耐心的看完后面所有的说明,awstats在进行日志统计时,
命令行统计增加: -databasebreak=day
报表输出时增加: &databasebreak=day
即可。

问题:
很多网站在流量从10万级增加到百万级以后就放弃了awstats作为统计,具体表现就是到月底的时候,统计数据会运行1天都运行不完。于是就改为webalizer或者analog了。其实这并非awstats统计效率不高:awstats很多丰富的统计指标:蜘蛛识别 浏览器识别,文件类型统计等都是比webalizer丰富的。webalizer要实现类似的统计力度也会出现性能问题。

原因分析:
性能的瓶颈在哪里呢:awstats统计缺省时按月统计,到月底时候记住的头20多天的历史IP等统计数据会是的数据文件变得很大(数百M),而awstats运行时,需要的内存量是数据dump文件的3-4倍。当这个monthly积累的数据导致awstats统计用到系统文件交换做内存的时候,效率就会降低了(处理速度会低2个数量级),于是出现了一天统计不完前一天日志的现象。

解决:
awstats丰富的统计指标还是很有用的,宁愿牺牲一下每天统计的精度。
1 控制一下数据截断的周期,不要让独立IP访问等历史统计周期过长;
2 一个网站已经达到日千万级的访问请求,按天的详细的数据统计也是必须的了。所以索性牺牲一下按月的独立IP统计(可以通过其他脚本处理awstats dump文件辅助实现),将日志改成按天统计,如果需要按月的汇总,可以利用awstats的dump数据成为一个中间数据源汇总统计。

按天统计后,awstats的输出文件会变成awstatsMMYYYYDD.confname.txt 每天一个统计文件,而报表的输出需要增加 &databasebreak=day&day=DD 来指定某一天的数据。

On the Google Maps team, our goal is not only to help you find local businesses, but also to enable you to quickly connect with those businesses, wherever you are. To that end, we recently introduced the ability to call businesses in the U.S. directly from Google Maps, and, as of today, users in Germany can send a business listing found on Google Maps Deutschland directly to cars enabled with the BMW Assist service. Drivers can then set it as the destination for the in-car navigation system, or they can call the business from within the car. No more having to write down the address and re-enter it in the car -- now you can just click and drive! Here's a video showing how this feature works (German version). We've partnered with BMW because they're a leading innovator in the automotive space, and they share our vision for a network-connected world.

As additional devices come online, we're excited to see what is possible, and we'll continue working to make the information that you need available to you when and where you need it.

Source favicon12:47 Headline Animator Overhaul, Part Three and One-Eighth » Burning Questions - The FeedBurner Weblog

Faithful readers are most likely aware of the minutiae that concern us here at FeedBurner inter-agency headquarters, especially when it comes to new features and notable drama such as "We're running low on decaf and 2% milk. OMG!" Today's enhancement to Headline Animator, the FeedBurner service engaged in a renovation comparable to the Dan Ryan expressway reconstruction project (minus the many reflector barrels), is all about expanding the reach of your content and making things look how you want them to look.

Place Your Content in More Places, Easily
It has been suggested by considerably more than seven of you that we should offer new capabilities to help grow your audience, and that's exactly what we're committed to doing with Headline Animator. It now features step-by-step instructions for placing your content on your MySpace page, a TypePad, Blogger or WordPress.com blog, a bunch of email programs, and "Other," a category we reserve for those interesting places whose names aren't reflected in the drop-down menu.

Word Wrap
Not everyone appreciates the sangfroid of a compact headline (note this post). For you and us, caution may be thrown to the wind by applying word wrap to individual post headlines. Word wrap is turned off by default so as not to potentially overwrite any background text, but since you know your Headline Animator better than anyone you may activate it by clicking a simple checkbox if the spirit (or more likely, the linebreak) moves you.

Finally, we acknowledge our fixation on this service lately, as evidenced by the Overhaul series. But that's only because it does so much for you, costs nothing, and keeps improving. If you've not yet put your content into this bite-sized, widgety treat, this week's update offers you some tempting new recipes.
