发帖数: 8397 | 1 Apple iPad 2 Smart Cover vs. InCase Convertible Magazine Jacket... Fight!
By Thomas Ricker posted Mar 3rd 2011 8:02AM
By now you've seen Apple's Smart Cover, right? The mind blowing cover (don't
call it a case) pretty much stole the show during yesterday's iPad 2 press
event, causing children to weep at the sight of our exploded bodies. Thing
is, we've seen the design before. Oh sure, Apple improved upon it
significantly, but there's no mistaking its InCase Convertible Magazine
Jacket heritage.... 阅读全帖 |

I have some data files which were originally written with a big_endian

Now, I try to use a fortran routine to read them with the compiler of

Where cdat is a string, say 198101.
When I compile the routine with gfortran, the system tip is: syntax error,

发帖数: 1057 | 6 发现现在convertible laptop是个趋势啊，各个厂家出了很多不同样子convertible,有
可以翻到背面点，有直接从键盘底座拔出来点，有屏幕可以左右或者上下旋转点，有屏
幕可以滑动点，等等。
比如lenovo yoga 2, sony vaio flip/tab/duo, dell xps 12, asuse,acer等等
有没有什么好点总结？买哪种比较好？
平时用途还是正常点用法更多，不过坐床上或者看电影什么感觉转换以下更好。

发帖数: 7142 | 10 你如果是想用 WS 的话就不要用 ESXi，那个是纯粹折腾.
Linux 基本上不需要什么 converter. 那个是给 windows 用的，
因为 windows 换个主板就经常启动不了了。linux 换主板都能
自己适应的。
你就这样好了，用 WS 建一个 Linux VM, 硬盘要比你现在要convert
的大一点点。用 Fedora Live CD （或者其他 Live CD) 的 iso
光盘启动到VM 的 Linux. 在 Live CD Linux 里面直接吧你的旧 Linux
server 的 disk image 拷贝过来到 VM 里面的 disk image。
有可能要修补一下 VM 下面的grub, chroot 到旧 linux image
里面从新跑一次 grub install.这样应该就可以直接启动了。 |

Another method is needed if we wish to be able to convert into objects of

master Converter 用于工程单位的换算，包含几乎所有单位制和单位量。

wiscy98 是一款功能强大的科学计算器，平时的加减乘除自不必说，函数
运算中甚至可以找到bessel，gamme等函数，统计，回归乃至简单的拟合，
最妙的是还可以画出函数图(有点象matlab中的funtool，不过要功能强大的

数列表，再也不用为找什么Avogadro常数翻书了，如果你经常忘的常数不

怎么设计能让这个系统保持稳定？监测负载上的电压电流保持一定，是不是要带个反馈回到

发帖数: 555 | 35 给你一个简单点的办法。
假设DC-DC converter 在恒定负载下，输出 2~5V， 对于做 DC-DC converter 的，实现这个应该不难
负载控制可以用一个current shunt monitor 电路，见附件。 假设你想要负载电流恒定在1A, 你可以串连一个 1 Ohm 的电阻， 设置reference voltage 为 1V， 放大器会自动调整 PMOS 的 Vgs, 从而保证 通过 负载的电流恒定为在 1A。
（电流大概0.3A）。
流继续增大，电阻进一步减小，导致烧坏。（重点不在这个负阻，负载的特性可以是
unpredictable的）。
实么（先不考虑cost）？如果输入是110V的AC呢？ |
