LaTeX Source Code Listing

LaTeX에서 소스코드를 넣어야 할때가 많았는데 그동안 fancyvrb만 쓰다가 캡션을 넣을수 없어서 http://faq.ktug.or.kr/faq/SourceCodeListing을 참고하여 하나 만들어봤습니다. 이쁘게 잘나오는군요.
float에서 나오는 형식대로 만들어봤습니다. float경우는 떠다니는 객체이기 때문에 소스코드가 1페이지 이상되면 위치를 결정하기가 힘든반면에 아래의 방식을 쓰면 원하는 위치에 넣을수 있다는 장점이 있습니다.

\newcounter{mysourcecounter}[section]
\setcounter{mysourcecounter}{1}
\makeatletter
\newcommand{\listofsources}{\@starttoc{xmp}}
\newenvironment{Source}[1]{\addcontentsline{xmp}{source}{#1}
  \vskip 1em
  \noindent\hrule height 1pt
  \vskip 2pt
  \noindent{\bf Source \thesection .\themysourcecounter} #1\stepcounter{mysourcecounter}
  \vskip 2pt
  \noindent\hrule height 0.4pt
  \begin{list}{}{\setlength\leftmargin{0pt}}\item[]}
  {\end{list}
  \vskip 2pt
  \noindent\hrule height 1pt
  \vskip 1em}
\newcommand{\l@source}[2]{\par\noindent#1 \dotfill {\itshape #2}}
\makeatother

사용법은 \begin{Source}{캡션} 이런식입니다.
아래는 간단한 예제.. documentclass같은건 직접 지정해줘야겠죠.

\begin{document}
  \fvset{fontsize=\footnotesize}
  \listofsources
  \newpage
  \begin{Source}{Hello World!}
    \begin{Verbatim}
#include <stdio.h>

int main()
{
        printf("Hello, World!");
}
    \end{Verbatim}
  \end{Source}
\end{document}

\listofsources로 사용된 소스코드의 목록을 자동으로 만들수 있습니다.

fvset에 numbers=left를 추가하면 아래와 같이 라인넘버도 출력할 수 있습니다.

쉘을 써보려면 당연히 Terminal 이 필요 하다.

sudo ln -s /Applications/MATLAB_R2008b.app/bin/matlab /usr/bin/matlab

Installation

Follow the steps below to install the SDK on your Mac OS X computer:

1. Download "Mac Leopard nao SDK" from the Aldebaran website.
2. Extract the contents of the SDK (.tar.gz) file in a directory (for example in "~/naoqi/").
3. Create an environment variable AL_DIR: export AL_DIR="/home/mylogin/naoqi/" (of course, change 'mylogin' by your login). It can be useful to set it in the .bashrc file for permanent export.

   Note:	AL_DIR must be set to the directory which contains the README file.

We are now ready to compile nao SDK examples.

Compilation instructions (HelloWorld sample)

There are two ways to compile a module:

• As an executable (remote modules): each modules package creates an independent executable stored in "$AL_DIR/modules/bin/". At startup you need to specify the IP and the port of the NaoQi running.
• As a library: each modules package creates a dynamic library stored in "$AL_DIR/modules/lib/". To make this library loaded by NaoQi, the $AL_DIR/module/lib/autoload.ini file needs to be updated with the name of your modules library.

CMake compilation tools is used to generate make or IDE project (XCode, ...).

Compiling modules as executable

Follow the steps below to compile NaoQi SDK examples as executable:

1. Be sure that the NaoQi executable and modules packages are not running.
2. Go to the $AL_DIR/modules/src/examples/ directory.
3. Create and jump into a temporary build directory (example $AL_DIR/modules/src/examples/build/).
4. Run cmake ..
5. Run the configuration command ccmake ..
6. Be sure that the HELLO_WORLD_IS_REMOTE option is set to ON.
7. Reconfigure by pressing c.
8. Quit cmake configuration by pressing g.
9. Then compile: make. The generated binaries are copied to the modules/bin directory.
10. Edit the autoload.ini file ($AL_DIR/modules/lib/autoload.ini).

    > The line helloworld must not be present.

    > "Autoload.ini" is used to load dynamic library at startup.

Now let's start modules packages executable:

1. Start the main broker by launching NaoQi executable ($AL_DIR/bin/naoqi).
2. Start helloworld executable ($AL_DIR/modules/bin/helloworld).

   > You will see some log in the mainbroker terminal.

3. Run the python file to test helloworld:

   a. cd $AL_DIR/modules/src/examples/helloworld/test

   b. python test_mymodule.py

At this point, the log message "Info : MyModule : Hello World!" is printed on the mainbroker (NaoQi) terminal.

Compiling modules as dynamic library

Follow the steps below to compile NaoQi SDK examples as library:

1. Be sure that NaoQi executable and modules packages are not running.
2. Go to the $AL_DIR/modules/src/examples/ directory.
3. Create and jump into a temporary build directory (example: $AL_DIR/modules/src/examples/build/).
4. Run cmake..
5. Run the configuration command ccmake..
6. Switch OFF the HELLOWORLD_IS_REMOTE option.
7. Reconfigure project by pressing c.
8. Quit cmake configuration by pressing g.
9. Then compile: make..

   > The generated libraries are copied to the modules/lib directory ($AL_DIR/modules/lib/helloworld.so).

10. Edit the autoload.ini file ($AL_DIR/modules/lib/autoload.ini) by adding this line: helloworld (before the [remote] line).
11. Start NaoQi executable ($AL_DIR/bin/naoqi).

    > The mainBroker starts and the module MyModule is loaded (cf log message).

12. Run the python file to test helloworld:

    a. cd $AL_DIR/modules/src/examples/helloworld/test

    b. python test_mymodule.py

At this point, the log message "Info : MyModule : Hello World!" is printed in the mainbroker (NaoQi) terminal.

Google Spreadsheets Tips: Gantt Chart (Microsoft Project-like) using Widget

Google Spreadsheets is a powerful web application to do everything you do using Excel. A nice way to use it is to manage a project plan with a gantt chart (microsoft project-like) and share it on-line with your team.This is a free and versatile solution to do that. This tutorial illustrates how to use Google Spreadsheets Viewpath Gadget to implement it.

Take a look at this spreadsheet


Step 1: Project Plan structure
First step is defiing your project plan structure. I suggest you to use this basic structure:

Column A: Task ID (WBS) (an unique ID which identifyes each task with a progressive number).
Column B: Task description (a short description of the activity).
Column C: Percentage of completion (0%-100%).
Column D: Predecessor (finish-start relationships between tasks).
Column E: Start date (task start date).
Column F: Finis date (task finish date).

The result is something like this:

All previous fields are required for viewpath gadget but, if you want, you can add other columns with other infos (for example the name of a resource assigned to each task, task duration in terms of day, ecc...). When your project plan structure is completed you are ready to add Gantt Chart using Google Spreadsheets Viewpath Gadget.

Step 2: Add Gantt Gadget
Click on Chart icon and select Gadget option.

In the Gadget window find and select Gantt Chart gadget (by Viewpath) and click on Add to spreadsheet button:

In the option window assign all required parameters to the correct column of your project plan structure (for example Start dates in this example are in the column E):

After assigned all columns, click on apply button and see the result. Now you can save your project plan , publish and share it with all member of your team.

외장하드 있으시면 일부 파티션을 나눠 타임머신으로 그 파티션을 타겟 설정해서 os 클린설치와 어플설치를 마치고 외장하드를 연결해서 한번 백업받아놓으면 나중에 OS DVD 넣어서 부팅후 타임머신 백업으로부터 복구하시면 될듯.

By default, Mac OS X's Finder keeps system files - which generally start with a dot, like .bash_profile - out of your sight.

But that makes editing one of these files extremely difficult if you, say, want to customize your Terminal prompt. To do so without firing up vim (if you don't know, don't ask), set Finder to show all hidden files. OS X FAQ has the details on how to do it.

In the Terminal type:
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

To set it back (that .DS_Store on the Desktop is hella irritating), execute those same commands, but just switch that TRUE to FALSE. Handy. — Gina Trapani
