来美国14个月总结
来美国已经14个月,日子过得飞快,英语受到严重的打击,信仰得到了新的冲刷,重新认识了什么叫做孤独,也重新认识了什么是家庭生活,新的研究方法和思维在惊奇过后重新进入平静的耕作期。太多事情需要坐下来静静的思考,总结收获,感谢那些良师益友。
生活需要人品
来美国已经14个月,日子过得飞快,英语受到严重的打击,信仰得到了新的冲刷,重新认识了什么叫做孤独,也重新认识了什么是家庭生活,新的研究方法和思维在惊奇过后重新进入平静的耕作期。太多事情需要坐下来静静的思考,总结收获,感谢那些良师益友。
使用微博已经有1年多了,应该是看微博,个人很少发布微博,断断续续发了92篇微博,主要都是个人的一些思考总结,确切说更像是个人的日记本。
Hi, Eiman
From a paper written by a engineer from China Mobile Shanghai. The wireless mesh network will suffer from the interrupt of spectrum, because there are many channels around the 2.4 GHz, and it is unauthorized spectrum. The second drawback is that the loss is obvious because of obstacle. So if we want to improve the QoS of WMN, we should solve these two problems first.
在江湖中,我们时刻需要整理自己的思路,理清脉络。
生活中有各种各样的问题,当你和房东有分歧,当你和同事有冲突,不胜枚举。人与人之间的问题永远无法说清楚,当关系发展到无法收拾的一天,也就是爆发战争的一天。以和为贵的精神永远能够适用,但是如果面对流氓和蛮狠跋扈的家伙时,一场战争或许能够痛快的解决问题,这在历史的长河中不断的得到验证。大多数战争都是双方或者一方认为无法和平解决争端,只有付诸武力,期望能够震慑对方。
而战争开打之后,态势的发展就不为人所控制,有时候厮杀几十年也不见分晓。社会比学校复杂很多,当政府无法保证合理权利的时候,一场战争就在酝酿,如果超过了忍耐,则一触即发。
上周末和Johann进行了一次很有意思的讨论,讨论的主题是:什么是生活?从出生到死亡,直到进入天堂到永恒,生命不止是在地球的这一段,所以除了关心事业发展,名和利,我们应该更加注重生活的平衡,事业,家庭,健康,友情和爱好的平衡。记得从小学一直到大学,在制定学期目标的时候,都会考虑德智体美劳全面发展这样的标准规范。从“德智体美劳”到“事业,家庭,健康,友情和爱好”的转变,意味着从校园走向了社会。生活的环境发生了变化,不能再留恋校园的宁静和简单。
平衡说来容易,但是在现实的中国,实现起来很难,目前我所认识的朋友中,能够算是比较符合美国平衡标准的只有一例,那就是一个60出头的老工程师,住在北京最大的社区--天通苑,有着40年的技术工程经验,算是老国企的下岗工人,平生爱好较多,能自制古筝,和爱人至今恩爱有加,对养生也有自己的理解。但是在我认识的50岁以下的朋友中,大家都在事业上透支着自己大部分时间。
当我还在探索事业的起点和什么是生活的时候,我悟出了5项平衡,但当我准备更好的平衡的时候,我还是选择了偏心,因为看着我身边最亲的亲人都在为未来的保障努力的时候,我没有理由不加入他们。在中国,再多的财富也无法拥有绝对的安全感,但是没有财富,没有事业,那安全感更是空中楼阁。所以在这五项中,我偏心于 事业(Career)和健康,我爱我的家庭,我的家庭也爱我,但是我要通过我的努力给他们的安全感增加一点,这也同样适用于我的朋友们。

The motivation can be described as followings:
I like to go to restaurants that are alive and happening. But often I find that the crowd noise makes it so I can't hear the person I'm sitting next to.The Cone Of Silence is a small electronics product that you can bring to dinner in your pocket, place on the table, and create a "noise cancelled zone" around the table you and your friends are sitting at.With the Cone Of Silence, you'll still get the feeling of being in a lively environment but you'll be able to hear your friends like they were in your home for dinner.The Cone Of Silence uses active noise control technology (http://en.wikipedia.org/wiki/Active_noise_control) to create the appropriate interference with the crowd noise in the restaurant.We can design a virtual room just for communicate with each other in voice based on Wireless Mesh Networks.Key attributes of the product are size (compact), cost (below $150), and battery powered. The batteries will be rechargeable like a cell phone and the battery life should be at least three hours.
Headset using in car when you are driving can be introduced here, Here we should consider about these issues carefully:
1/ How can select the voice input so that nearby users can speak to the device.
2/ How to make listener feel comfortable just like without headset?
3/ How to be secure of voice?
4/ How to manage the spectrum?
When we transfer our mobile phone to another mobile operator, such as from China Mobile to China Unicom, or from Verision to AT&T, it is hard work to notify all friends in our contact list. So we need the tool to transfer our text message or voice message to our current mobile device.
We can get more and more abilities from Cloud computing app. But this
type of cloud is far away from us, so it is difficult to use that
anytime/where because of access bandwidth, especially when there are a
large number of users in the same area of wireless network. We design
the concept of virtual cloud around you, so you can access to cloud
anytime/where.
