2月15日,寒假结束了,幼儿园开校了,把孩子送到上学期的那个幼儿园读小班下学期了,学费300元,因为保险费管1年,所以这学期就不缴保险费了。

很惊叹孩子的记忆力和故事表达力
这两天晚上,8:30分我就让孩子上床睡觉,她当然是睡不着的,于是,我就给她讲故事。讲的内容是她平时看的动画片:小鼹鼠的故事,如小鼹鼠和小老鹰,小鼹鼠和伞...
没有想到,我讲着讲着,她会接着我讲的故事讲上一段,而且有声有色,故事情节也不差。我真是惊叹,原来以为她看动画片只是好玩,看了就忘了,没有想到她竟然记下来了。
要知道,她还不到3岁呢。
也许,孩子的智力开发得比较早,我们是不是给她的学校教育应该适当超前点?当然,想把她培养成“神童”是不可取的,中国原来的实践证明“神童”不是培养的,原来培养的“神童”多是失败的例子。
孩子的童年应该主要是习惯和品德的塑造,书本的学习应该是其次的,我认为如此。
孩子的咳嗽
白天不咳,晚上睡觉的时候容易咳,热了要咳,所以被子不能盖厚了;冷了也要咳,所以要挨着大人一起睡,这样也可以预防她晚上踢被子。晚上孩子有时咳起来,咳嗽声就像鼓一样在心上敲。
总的说来,我们孩子的衣服要比我们大人穿得少点才行。因为她的火气好像比较大,而且一天又不停的运动。
目标内容的页面需要精心设计
像www.43things.com,目标完成的人可以充当指导后来者的“老师”,这个页面可以展示哪些人加入了这个目标。可以展示征对这个目标的提问。征对这个目标投放了相应的google广告。所以,这个页面在43things.com的rss订阅中只给了链接也是有它的深意的。因为,网页上可以方便提供更丰富的信息,比如广告。
不要排斥广告
恰当的广告是对社会的一种贡献。它可以沟通供求双方。像www.43things.com,征对某一个目标,投放对应的google广告,这样,给了实现这个目标的人一个辅助目标实现的选择。也使商家的服务得到认识,使他们实现自己的理想和追求。
我今天就收了两封讲网络联合赚钱的群发邮件。从而联想到学习日记也可以做成这种联盟的形式,自助建站,等等。自助建站的域名可以是:***.learndiary.com的形式。
所以,广告也有好处,不要因为过度广告的招人讨厌而全面否定它。
目标的分类和结构
分类:实践目标,学习目标
结构:实践目标和学习目标可以互为前提?
个人的目标树?目标之间的关系是单根树?还是可以是网状?
从数据结构和理论定律的高度进行目标的分类和结构的提炼。

Re: NESTED BEGIN EXCEPTIOn
Rakesh,
You're creating more TCP/IP connections than your OS is configured to handle. Are you using a connection pool? Is there some other process which creates many TCP/IP connections on your system?

David,
You're creating connections faster than your OS can recycle sockets out of TIME_WAIT status. That is why you get the exception you posted.
Connections should be relatively long-lived objects, maybe you should investigate re-using them within your application or via a connection pool?

Yes Mark, you are right!!! In addition I would like to warn developers using Win XP with SP 2 that SP 2 introduces a new TCP/IP feature: the number of possible TCP connection attempts is limited to 10 per second. I think that’s why getting an exception related with TCP connections it’s so easy.
Thanks for your help and time,
Best regards,
David Benaderet.
学习日记rss订阅方案设计(希望得到您的意见或建议)
看了www.43things.com的rss订阅方案和roller的rss方案,结合学习日记的特点,提出学习日记的rss订阅方案。
1、个人的订阅:
1)、我进行中的目标的最新39篇日记;(参数:type=diary.processGoal,userName=tom)
2)、我写作的日记的最新39篇评论;(参数:type=advice.diary,userName=tom)
2、全局的订阅:
目标的订阅:
1)、最近创建的39个目标;(参数:type=goal.last)
2)、加入人数最多的39个目标;(参数:type=goal.mostJoin)
日记的订阅:
1)、最近写作的39篇日记;(参数:type=diary.last)
评论的订阅:
1)、最近提交的39篇评论;(参数:type=advice.last)
3、征对某一个目标的订阅:
1)、这个目标的最新39篇日记;(参数:type=diary.goal,goalID=1)
2)、这个目标的最新39篇评论;(参数:type=advice.goal,goalID=1)
订阅的格式:
1、订阅的目标:
目标题目
×××在什么时候创建了目标×××:
目标内容(www.43things.com中目标的具体内容只有在网上看,它在这个页面有实现这个目标的相关的广告。学习日记可以考虑这种沟通用户的服务提供者的恰当的沟通方式)。
2、订阅的日记:
日记标题
×××在什么时候为×××目标写作了日记×××:
日记内容
3、订阅的评论:
评论标题:
×××在什么时候评论了目标×××(或评论了目标×××下的日记×××):
评论内容
使用rss2.0规范,用rsslibj来生成(实际它可以生成0.92或1.0等规范的,但是没有atom的规范,这个公共库项目在2003年就停止了更新,估计是作者认为这个库已经完全满足它的主要目的了:专门用来生成rss文件),全局订阅单独放在一个页面中;某个目标的订阅分别放在所有目标页面的各个目标的条目中、目标的内容中、目标的日记列表中、目标的日记内容中。
一个好像不错的web2.0相关开发社区http://developer.yahoo.net
来自:http://blog.matrix.org.cn/page/zhenggc?entry=yahoo%E4%B9%9F%E6%90%9Edev 的介绍。
里面有个yahoo ui lib好像是我非常需要的,收藏一下先。
下面是它的首页的介绍:
Innovate.

New! - Yahoo! User Interface and Design Patterns Libraries
Everyone talks about Web 2.0. Talk is cheap. How about some real help? Just in time for Valentine's day we're giving you a delicious candy box of tools and guidelines for building cutting-edge dynamic web sites.
First, there's the Yahoo! User Interface Library. The UI Library is a set of JavaScript components that let you quickly add all kinds of really nifty features to your web site, from dynamic UI elements like drag and drop, tree views, and animation; to underlying functionality like custom events and easy-to-use cross-browser XMLHttpRequest connections. Its a small easy-to-use framework for building AJAX applications. And get this: Its free to use and its open source (BSD license). Better than flowers any day.
Code is cool, but howabout some advice, too. We've also got the Yahoo! Design Patterns Library, where our best visual and interaction designers have gotten together and created a set of patterns and guidelines for design in a Web 2.0 world. Here you'll find ideas on the best ways to implement web site elements, along with pointers to examples and the tools within the Yahoo! UI Library that will let you do it. Today's Pattern Library is just the beginning -- expect this part of the site to grow quite a lot over the coming months.
Our Yahoo! UI folks, in addition to the insane amount of work they did to bring you all these cool tools today, have also started a blog over on yuiblog.com to keep you updated on stuff going on in the Yahoo! UI world and to get your feedback on patterns and tools. Drop over and say hi!
