在ubuntu下, 把txt裡面的windows換行符號改成unix換行符號 (好長的標題啊啊啊啊XD)

最近在windows編輯了一堆txt檔, 然後丟回ubuntu的時候才想到忘了把換行符號改掉. 囧

總共有100個檔案吧, 一個一個開會死人 ˊ_>ˋ

http://stackoverflow.com/questions/13589895/shell-command-to-strip-out-m-characters-from-text-file
然後這上面這個討論, 看到 dos2unix 這個工具!!

直接用apt-get就可以裝了

而且後面直接加檔名, 不需要輸入 output filename, 就直接把那個檔案的換行符號換掉 (好方便XD)

如果有5個檔案, 就可以一次處理完

ex:  dos2unix  file1.txt   file2.txt   file3.txt   file4.txt   file5.txt

Fedora core 5 更新 bash

原文:
Unix /Linux 的Bash Shell 出現重大漏洞，危險等級可能超越 Heartbleed
"該漏洞可能讓駭客遠端執行惡意程式，影響GNU、Linux及Mac OS等基於UNIX的各種作業系統。有資安業者認為，此一被稱為Shell Shock的漏洞影響程度可能與Heartbleed相當，甚至更甚於Heartbleed。"
http://www.ithome.com.tw/news/91107

由於server還沒換新系統 (好懶 XD)
不過還是更新一下bash好了  orz....

檢查的語法:

env x='() { :;}; echo XD' bash -c "echo This is a test code"

更新前打上面那串指令, 會出現

XD
This is a test code

更新後打同樣指令, 就只看到

This is a test code 

FC4的更新步驟如下:

 * 安裝bison (之後make bash source code會用到yacc, 這個在bison套件裡面)
    - yum install bison
 * 下載相對應的bash source code 與 patch (我是先建立一個資料夾來放檔案)
    - mkdir update_bash
    - cd update_bash/
    - wget https://ftp.gnu.org/gnu/bash/bash-3.1.tar.gz
    - tar zxvf bash-3.1.tar.gz
    - nano patch_all.sh  (新增一個sh檔, 內容如下方粗體字)
for i in $(seq -f "%03g" 1 23);
   do
   echo "Getting ... http://ftp.gnu.org/gnu/bash/bash-3.1-patches/bash31-$i";
   curl "http://ftp.gnu.org/gnu/bash/bash-3.1-patches/bash31-$i" | patch -p0 ;
done
    - cd bash-3.1
    - sh ../patch_all.sh

   - 之後patch完, 就 ./configure, make, make install

這樣應該就好了 XD

lp_solve in matlab

弄好久, 也不知道這樣做對不對....  囧~~~

(這邊只針對windows做記錄, linux的matlab我之前好像裝不起來 orz.....)

官方說明:
http://lpsolve.sourceforge.net/5.5/MATLAB.htm

其他說明 & 相關心得
http://www.cnblogs.com/kane1990/p/3428129.html
http://www.cnblogs.com/kane1990/RecentComments.html

-------------------------------

先去sourceforge下載相關檔案
http://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.0/
 * lp_solve_5.5.2.0_MATLAB_exe_win32
 * lp_solve_5.5.2.0_dev_win32
下載列表也有64位元的, 稍微瞄一下應該都找的到

 * lp_solve_5.5.2.0_dev_win32.zip解壓縮, 進去資料夾, 把 lpsolve55.dll 複製到 C:\WINDOWS\system32
    - 我還在用XP. XD

 * lp_solve_5.5.2.0_MATLAB_exe_win32.zip解壓縮, 裡面還有一個bin/win32的資料夾, 把裡面的mxlpsolve.dll和mxlpsolve.mexw32複製到跟mxlpsolve.m同一層資料夾

我的做法是, 在C:\Program Files\MATLAB\$your_version$\toolbox裡面多開一個 lp_solve 資料夾, 然後把這些檔案複製到這裡. 資料夾裡的檔案有:
ex.m
example1.m　example4.m　lp_maker.m　mxlpsolve.dll
example2.m　example5.m　lp_solve.m　mxlpsolve.m
example3.m　example6.m　lpdemo.m　mxlpsolve.mexw32



 * 接著打開matlab, 設定環境變數. File -> Set Path, 然後把剛剛的 C:\Program Files\MATLAB\$your_version$\toolbox\lp_solve 放進去

 * 在matlab終端機直接打 lp_maker 和 lp_solve 都可以看到正常訊息
 * 可是我打 mxlpsolve 一直都跑出警告訊息, 囧~~~~ 後來看了一下mxlpsolve.m的檔案, 裡面都只有display的程式碼, 我也不知道我看到這些警告訊息是不是正常 orz

後來查到別人的心得: http://www.cnblogs.com/kane1990/p/3428129.html

就照他的程式碼跑了一下, 然後發現似乎可以求解!?

f = [4 2 1];
A = [2 1 0; 1 0 2; 1 1 1];
b = [1; 2; 1];
l = [ 0 0 0];
u = [ 1 1 2];
lp=mxlpsolve('make_lp', 1, 3);
mxlpsolve('set_verbose', lp, 3);
mxlpsolve('set_obj_fn', lp, f);
mxlpsolve('add_constraint', lp, A(1, :), 1, b(1));
mxlpsolve('add_constraint', lp, A(2, :), 1, b(2));
mxlpsolve('add_constraint', lp, A(3, :), 0, b(3));
mxlpsolve('set_lowbo', lp, l);
mxlpsolve('set_upbo', lp, u);
mxlpsolve('write_lp', lp, 'a.lp');
mxlpsolve('get_mat', lp, 1, 2)
mxlpsolve('solve', lp)
mxlpsolve('get_objective', lp)
mxlpsolve('get_variables', lp)
mxlpsolve('get_constraints', lp)

就姑且相信這樣的安裝流程是對的吧 XDDDD

------------------------------------------------------------------

補充:
後來在win7(64bit)的電腦上用同樣的步驟去複製檔案, 結果執行  mxlpsolve 完全沒有錯誤訊息 XD......

安裝libg2c.so

照這個網頁的步驟, 安裝檔案後

回到R裡面 ./configure 就解決這個錯誤訊息了 XD

checking whether mixed C/Fortran code can be run... configure:
WARNING: cannot run mixed C/Fortran code
configure: error: Maybe check LDFLAGS for paths to Fortran libraries?

http://gnxas.unicam.it/XASLABwww/pag_gnxas/gnxas_install_g77lib.html

  install.sh
  
• install the g77 package using the following command:
  sudo ./install.sh 

 --------------------------  

可是後來make的時候遇到另一個錯誤訊息

Invalid declaration of or reference to symbol `tiny' at (^) [initially seen at (^)]
make[4]: *** [dlamch.o] Error 1

然後安裝  openjdk-6-jdk 就好了 XDD

蝦咪喜R ?

之後可能要來研究這個了!? XDD

Introduction to R

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.
One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control.
R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

神奇的滑鼠中鍵 XD

之前買了一個無線鍵盤滑鼠組 (mk520)

後來有送修過一次, 因為滑鼠中鍵無法使用 ~"~

然後這兩天又出現這個症狀了, 囧....

中鍵超方便的啊啊啊啊, 可以直接開新分頁 & 關閉分頁
不能使用很不方便耶 (無誤)

剛剛心血來潮去羅技的官網找找看有沒有啥程式可以下載
然後抓了一個setpoint的程式

結果裝好後竟然就恢復正常了 = ="
而且滑鼠的速度好像也變比較快了(?) XDD

反正重點是滑鼠中鍵恢復正常 科科~

--

補充: 後來還是不能用 ~"~
看樣子應該是中鍵又怪怪的 orz

使用ipe的ipelet跑power diagram

搞了老半天, 結果超簡單的, 用apt-get裝一下就好了 = ="

我還在那邊用source code下去編譯, 然後diagram的選項一直跑不出來  囧....

這次用的指令超簡單, 只有一個 XD
sudo apt-get install cgal*
 
這個打完後, 他會去安裝這四個東西
libcgal-demo
libcgal-dev
libcgal-ipelets
libcgal8

(ipe好像是本來就用apt-get裝好了!? 有點忘記順序 XD)

如果IPE裝好了, 上面那四個也裝好了
打開IPE, 會看到 Ipelets 裡面有 power diagram 可以用!!!!

自己畫幾個圓, 然後再去按那個選項, 整個power diagram就畫好了 (超感動)

只是接下來就要去研究那些點的座標位置了 ~"~

安裝CGAL

今天試著安裝CGAL, 可是有缺一些套件, log是說沒有GMP, MPFR, boost

然後裝完這幾個套件後就可以cmake了

sudo apt-get install libgmp3-dev
 

sudo apt-get install libmpfr-dev libmpfr-doc libmpfr4 libmpfr4-dbg

sudo apt-get install libboost-all-dev 

安裝octave - 2

終於成功安裝geometry了~~~~~~!!!  XD

大致的步驟如下 (不確定對不對)

sudo apt-get install octave
sudo apt-get install liboctave-dev

裝好後, 用sudo開啟octave

sudo octave

# 先裝 general套件, 他是geometry的相依性套件
pkg install -auto -forge general

# 然後再裝geometry
pkg install -auto -forge geometry

然後就看到radicalAxis了!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

安裝octave

呃.... 好懶得打 XD
---------------------------------
[使用apt-get]

直接用apt-get install octave有可能會裝到舊版的, 如果想要安裝新版的話, 可以加入這些apt站台

sudo apt-add-repository ppa:octave/stable
sudo apt-get update
sudo apt-get install octave

然後就會自動安裝新版的octave了~ XD 

[ref] http://askubuntu.com/questions/194151/how-do-you-install-the-latest-version-of-gnu-octave

---------------------------------[無法執行]
在終端機打octave, 然後出現這個的話

bash: /usr/local/bin/octave: No such file or directory

可以打這幾個指令去修復

type svnsync

hash -r

或者是直接打這個 

hash -d svnsync 

[ref] http://unix.stackexchange.com/questions/5609/how-do-i-clear-bashs-cache-of-paths-to-executables

總而言之, 遇到了一堆缺少套件

不過看起來應該是不影響執行啦 XD.....

後來才發現這個網只有提到一些相依性套件 ˊ_>ˋ

我要安裝geometry套件啊啊啊啊啊~~~~~

為啥都裝不起來  =口=
