标 题: Help: how to use Eclipse as C++ IDE in Linux?
发信站: BBS 未名空间站 (Tue Jan 8 14:20:38 2008)
Redhat Enterprise 4.0 x64.
Downloaded and unpacked Eclipse. When running it, got the following error
message consistently. Is there any setting that I need to modify to install
Eclipse? Any other free C++ IDE in Linux to recommend? Thanks a lot!
JVM terminated. Exit code=1

pack the list into binary then unpack them;
but throwing out web links, didn't really help.
and you have more WB than me, so I guess you will be fine if I don't pay you
any. |

Never has a tweet been more true, or potentially more disastrous for a

Android wasn't truly open, tweeted that anyone could fork - i.e., modify -
Android, making it "open" in the truest sense of the word.
Unfortunately for Google, many OEMs took Rubin at his word.

ByteString.Lazy 和 ByteString.Lazy.Char8 怎么会不兼容呢，后者是为前者提供向
Char 转化的工具（直接 truncate），但是操作的结果和对象可都是 ByteString.Lazy
啊。所以你用 Codec.Archive.Zip 读写的 ByteString.Lazy.ByteString 类型的值，
直接用 ByteString.Lazy.Char8 里面的函数操作即可。
不过说实在话，我不知道你为什么喜欢用 Char，直接用 Word8 并没有很不方便。
尤其是 String literal 可以直接使用 {-# LANGUAGE OverloadedStrings #-}
如果你说的是 ByteString 和 [Char] 之间转换，只需要用到 ByteStirng.Lazy.Char8
.pack 和 unpack 两个函数，其它不需要考虑。如果你需要 UTF8 编码转换，用 utf8-
string 这个库。 |

发帖数: 474 | 15 比如我下载的字体宏包psnfss, 安装说明说
Obtain the archive files lw35nfss.zip and freenfss.zip from
CTAN:macros/latex/required/psnfss. If the file system
layout of your TeX system complies with TDS, unzip them in
the texmf root directory (usually named texmf) of your TeX
system; all files will be unpacked into the right
directories then. Otherwise you have to sort out manually
the files from the .zip archives and copy them to the
appropriate directories of your TeX system.
但我找不到texmf这个目录。怎么办？

发帖数: 1879 | 16 Usually uname -a would report the cpu type (and hopefully the speed
as well).
uname -X reports the #of cpu's.
fpversion may be available on your machine. It can check the cpu
speed...
My suggestion to you if you really want to know more information
about your CPU is to download any system patches from Sun, unpack
them, and there are usually some scripts designed to detect many
system wide informations. |

basically ppl use SVD to do pseudoinverse.
1. Let B = pinv(A), where pinv(A) is the pseudoinverse of A, m x n matrix.
i.e., ABA = A
2. SVD (Singual Value Decomposition)
Let A = USV', where U & V are orthogonal matrices (U'U=I) and S is
a diagonal matrix.
3. -1
B = V S U'
so what u need is a SVD algorithm. U can get it from

1) It is very important to use boxes with same dimension. You don't need to
purchase them from Uhaul, Lowes, or Homedepot. My wife has been collecting
lab supply boxes from the medical center where we are working at.
2) Use vertical space more wisely; label your boxes as ‘heavy’, ‘medium’
, and ‘light’, according to their weight, therefore you know how to stack
them.

，欢迎参加。站内联系。
四点建议：
1. MAKE A LIST !!
2. 把STEP3考了。
3. CASE PRESENTATION PRACTICE。
4. 把MKSAP 14 OR 15 做二遍，很多临床用的GUIDELINE上面都有，比STEP3更
有实际意义。
刚刚翻出来去年prematch后发的一个贴子，供参考：
