2月22日 Talking about "Monster Get You the Interviews; We Get You the Jobs!"我姐吹,我也吹。不知道,被她train过的,目前的成功率怎么样?我得开一个B2签证培训,我目前的战绩是培训了5个,5个都一签pass,或者在新东方底下挂个名,开个分部 Quote "Monster Get You the Interviews; We Get You the Jobs!" 2月21日 Talking about I Love You, but You Love Meat --- a message received on Valentine's dayFunny story. Quote I Love You, but You Love Meat --- a message received on Valentine's day 2月20日 Back from the court老婆从court回来,但是没有等到判那个人就撤了,主要人太多了,不知道要等到什么时候。把要求赔钱的资料给他们了就。我这回来在Columbus Court的网站上一查那个哥们,没戏了。哥们老黑,惯犯,在Columbus就有11条records。从99年开始,到07年。他之所以被抓住是因为10月份有一次robbery,小子够猖獗的,所以被抓了。估计这个哥们肯定没钱赔,白高兴了,明天给court再打个电话问问,明天再汇报。 Thinkpad T40 series Video Chip Design FlawMy Thinkpad seldom crashes. But when it does, it means a serious problem. I had Blue Screen of Death (BSOD) one year and a half ago and later it completely crashed. When you turn it on, just black screen. Then I sent it back to China and did a BGA work. Then it was fixed. But now the problem starts again. Below is a detailed description of the "Ball Grid Array" (BGA) design. This is a stupid design. Lenovo should have recalled this model due to the design flaw. People who have T4x should unite together, send emails to Lenovo and have them recall these laptops. Quoted from a professional: "The problem is that the video controller chips separate from the motherboard, in the newer laptops. Newer (past few years) video controller chips are attached to the motherboards using what is called "surface mount" technology. As processor transistor densities increase, it becomes almost impossible to attach them to motherboards using pins. This is because the pins would have to be so close together, that the soldering process would end up cross-soldering pins (soldering one pin to another.) Surface mount technology uses what is called a "Ball Grid Array" (BGA), which means they now use an array of tiny solder balls to attach the chip to the motherboard. The weakness of this method, is that the solder will crack over time, either from differences in thermal expansion in the motherboard and chip, and/or more commonly from the motherboard flexing slightly. Whenever you pick up the laptop, place it on an uneven surface, adjust the screen angle, etc., the case flexes slightly. The motherboard is attached to the bottom of the case, so it also flexes. This is why you can temporarily fix the problem by pressing on the case. Chips attached with pins (like the CPU) are largely immune to this problem, because the pins can flex along with the motherboard, without cracking like solder does. Some people have fixed this problem by shimming the area between the graphics chips and the underside of the keyboard (not possible where the video chip has a fan on it. Also, some models, like the R40, have a poorly designed heat sink for the video controller, that only comes in contact with one side of the controller; this exacerbates the motherboard flexing problem, because of the uneven pressure applied to the chip. A url that discusses this problem is http://forum.thinkpads.com/viewtopic.php?p=237501&sid=07fe537a23bb9753c3709261b44c3880 This is indeed an example of very poor design by IBM engineers. Both
the bad video controller heat sink design and not reinforcing the
motherboard (by attaching it to a vented aluminum under plate, which is
in turn attached to the case,) are major design weaknesses. We can see
from some of the above postings, that repeatedly replacing the
motherboard isn't a long term fix. I believe IBM isn't the only company
who made this mistake. I think you'll find that almost all laptop
manufacturers have committed this error. So now, we have a situation
where laptop computers have become a disposable item. Adding an under
plate to the motherboard should fix the problem; it will add a pound or
so to the weight, but that is a small price to pay for reliability." 2月19日 第一代移民确实想想,第一代移民的生活就是艰辛呀。昨天和一哥们聊天,说每天晚上下班还能看看书,好羡慕呀。想想自己成天都是疲于奔命,忙了这个忙那个。老婆有时说,咱们累死累活为了啥? 为了今后物质生活好点?为了挣点钱给父母养老?还是为了以后自己的娃? 结论是,别废话,好好干活吧。 Quote blog worthy 2月9日 集结号下载请点击 CD1 340MB☞ http://www.megaupload.com/?d=T4763TCB CD2 318MB☞ http://www.megaupload.com/?d=KXVJ39E4 发现一个下电影的好地方,大家没事可以解解闷,很多都是MU的。 http://www.zorland.com/ 2月3日 饺子昨天自己弄了次饺子,follow老妈的菜谱,馅是有啥算啥的那种,基本上,肉,木耳,鸡蛋。葱姜建议去买个chopper,切起来太痛苦了。买的现成的饺子皮,很省事,做水的功夫,就包了20多个。吃起来还不错,没少放香油。 Quote 南瓜馅饺子 2月1日 我们家的传统这两天发生的事情太intense and ironic啦!绝对的blog-worthy! 刚刚我姐来电话,猜告诉我发生了啥?她的车刚刚被砸,车里的GPS被偷!我这个赔多少还前途未卜,她这又添乱呀!而且据说警察连指纹都没取,估计没戏了。 老婆说,被砸车,丢GPS都成我们家传统了。 米国无望啦! |
