来自主题: Hardware版 - 请问costco dual monitor 好用吗?
我的monitor是24吋。觉得很多时候想要用dual monitor,特别是做graphic design时。
我现在monitor是买dell studio 8000时配的。看costco viewsonic dual monitor 在
降价。不知好用否,链接如下。不知是否带speaker,title 上写有,下面
specification 却没写。

来自主题: Hardware版 - 谁科普下dual band router
这个dual band router满天飞了,一直没明白2.4g和5g是如何simultaneous work的?
设置router的时候,2.4G和5g分别设置一个ssid,假设网卡也支持dual band(3t3r)
,是不是只要连上了5g对应的ssid,就能在2.4g和5g之间自动转换了?
比如linksys e4500,如果是2.4g和5g都工作,最大速度是不就是900mbps?单独链接2.
4g或5g则最高速度450mbps?

来自主题: Hardware版 - Dual Dell U2412M or One Dell U2713HM?
I just try to use up some of my expiring Dell gift cards to upgrade my home
monitors. I could either purchase 2 Dell U2412M (16:10,1920x1200, USB2.0 Hub
, no HDMI, e-IPS) to do Dual Monitor setup or just one Dell U2713HM (16:9,
2560 x 1440, USB3.0 Hub, HDMI, AH-IPS). The total price for these two
solution are almost the same.
I will use these home monitors mainly for internet, youtube, movies, coding
and documents. I almost do not play any games. Should I go with dual U2412M
or just one U2713HM... 阅读全帖

来自主题: Linux版 - SSD上是dual boot好还是vm好?
搞了块256G的SSD
考虑是linux host + win guest
还是dual boot
用windows主要是
1. office
2. 万一回国,网银之类
3. 我目前用mint,在有些网络环境遇到过wifi巨慢的问题
4. 有些网络会议系统要装插件,对linux支持普遍不好
dual boot觉得浪费硬盘空间,win自己加上预留的空间,估计60GB没了
而且要处理office还得reboot
用vm万一遇到wifi问题就废了,而且硬盘空间也要不少
而且不知道ssd上用vm有没有什么要注意的?
有什么建议没?

来自主题: Windows版 - Help on dual boot -- XP and Linux
Hello,
Just had a Dell precision 690 workstation, with Enterprise Linux
preinstalled.
I am now thinking make the machine dual boot, XP and Linux. (both are 64-bit)
Since Linux is preinstalled, I plan to use the XP CD to format the HDs. BTW:
I have two HDs.
While I restart by CD, after some copying, I was told it can not find the
Hard Disks!
Does anyone know what I am doing wroing? How to make the Dual boot? Thanks
very much!!!!

标 题: 求助:关于Dual Boot Win7 & Ubuntu的问题
发信站: BBS 未名空间站 (Sat Jan 21 16:34:01 2012, 美东)
情况有些曲折,大概是这样的:
最早只有一个winXP,后来又装了个win7组成winXP & win7 dual boot系统。最近把
winXP分区(硬盘的第一个分区)格式化后装上了Ubuntu 11.10。可是Grub2 boot menu
里面没有win7的条目。我尝试了多种恢复方法,比如用win7安装盘进入recovery选项,
然后用bootrec命令,结果都不行。
怎么做才能修复win7 bootloader呢?
多谢呢。

我回到他的实验室一起作一课题,以Adjunct Assitant Professor的身份。我利用自己
的业余时间作实验,课题进展很顺利,现在准备在NIH申请课题,因为这个课题从设计
到实验,都是由我独自完成,老板说我们可以一起申请grant,请问象我这样的情况,是
以dual PI 好,还是以co-investigator好?我听说PI,co-PI和dual PI 都不能从
grant里给自己发工资,但co-investigator可以,不知是否是真的?请版上高人指教。

散热和scaling的问题。
现在65nm很成熟了,45nm的东西都陆陆续续出来的。正在开发的是32nm。22nm已经开始
研究了。再往下谁也不知道能做到什么程度。
从performance来讲,single core 2G的cpu > 1G Dual core的cpu > single core 1G
的cpu。类似的4 Core比Dual core要好,6 core会比 4 core好。但是继续往上就很难
说了,主要取决于芯片的设计和软件的支持。很有可能20 core会比16 core差。

有次和人谈这话题,我说看过资料,大概知道Asyn FIFO怎么设计,对方就让我画来看
看。我就画了block diagram,正要说怎么控制over/underflow,对方就说这些都不重
要,最难设计的就是那个dual port SRAM,我愕然,因为之前都不知道这个是难点。
我想问的是,怎么才能在学习中注意这个难点,或者说这类难点呢?因为像Asyn FIFO
,我没上过课,是自学的,就是google些相关的paper大概看一下,然后再看些HDL的例
子。在这些例子里面,dual port SRAM都是以很简单的形式出现,几句HDL就完成了这
个block,以至于我以为这样就OK了...
希望大家能指点下,在学习VLSI相关的技术时,怎样才能注意到这种在industry也许是
常识,但我这种闭门造车的人却忽视的细节呢?有些什么比较好的资源,或者学习方法
上要注意的呢?
非常感谢!

来自主题: Mathematics版 - H^1_{0,\Gamma_0}的dual space是什么?
我们知道H^1_0的dual space被定义为H^{-1},
那么H^1_{0, \Gamma_0}的dual space是什么?还是H^{-1}吗?
其中H^1_{0, \Gamma_0}只在\Omega的一部分边界\Gamma_0是0.
或者换一个问题,任取一个H^{-1}里的函数u, 如下线性泛函
= \int_{\Omega} u v for any v \in H^1_{0,\Gamma_0}
是不是一定也是H^1_{0,\Gamma_0}的有界线性泛函?

很奇怪为什么不用single cam呢?single cam没有同步问题,简单很多。虽说缺点是不

2. 当指定了其中一个sim用data,另一个sim能否disable,而不用dual standby?
