설치 항목 Software to install

파이썬 프로그래밍 언어 Python Programming Language

Anaconda 5.x Python 3.6.x version

명령행에서 실행해야 할 경우, 경로에 추가하도록 설정 To run from a command line, configure to add python to the PATH
경로 이름에 한글을 사용할 수 없음 Use ASCII characters for path name
윈도우즈의 경우, 설치 후 가상 환경 생성, 전환 2회 이상 확인 추천
For Windows, after install, please check creating a virtual environment and switching between environment more than twice.

깃 버전 관리 소프트웨어 Git Version Control Software

CUI

아래 소프트웨어를 설치 Please install following software

Git for Windows

간단한 추천 사항 A few simple recommendations

명령행에서 사용 Command line interface
실습실 환경에서는 credential manager 설치 삼가
Credential manager may not be a best choice for a computer lab
아래 IDE 가운데 Microsoft Visual Studio Code 선택시 다음과 같이 생각해 볼 수 있음
To use Microsoft Visual Studio Code among IDEs below, an administrator may consider followings

항목 Key	값 Value
git 기본 편집기 Default editor for Git	MS VS Code
경로 환경 조정 Adjusting Path environment	Use Git from the Windows Command Prompt
터미널 에뮬레이터 Terminal emulator	Use Windows' default console window
자격 인증 관리자 활성화 Enable Git Credential Manager	전산 실습 환경의 경우, 선택 해제 If computer lab, unselect

이후 MS vscode 에서도 한두가지 추가 설정을 실시하면 내장 터미널로 git-bash 를 사용할 수 있음
With a few additional configurations in MS vscode, one could use git-bash as the integrated terminal.

PyCharm Community

PyCharm 을 실행시키기 위해 Java Development Kit 를 설치해야 할 수 있음 (2016 09)
PyCharm may need Java Development Kit to run.

Microsoft Visual Studio Code

Anaconda 설치 후 설치 선택 가능
Installation button available at the end of Anaconda installation
다운로드 받아서 설치도 가능
Possible to download and install from the website
Setup Overview / Python Configuration Instruction
Windows 에서 git-bash를 내장 터미널로 사용하려면 다음과 같은 추가 설정이 필요함.[참고]
In Windows, to use git-bash as the integrated terminal, following additional settings would enable it.[Ref]

`jupyter` 노트북 실행시키는 법
How to start a `jupyter` notebook

이 저장소 는 주로 jupyter 노트북으로 만들어져 있음.
This repository is mostly written in jupyter notebook.
jupyter 노트북은 웹브라우저를 통해 프로그램 코드를 수정 실행하고 LaTex 수식을 포함한 문서 작성이 가능함.
Through a web browser, jupyter notebook enables editing & running program codes and writing documents including LaTex equations.

적당한 folder 를 만듦 (예를 들어 User/Documents/SolMech/)
Make an appropriate folder (e.g., User/Documents/SolMech/)
Git 또는 SourceTree 를 이용하여 위 folder 아래 이 원격 저장소를 git clone
Using the Git or SourceTree, git clone this repository under the folder
cmd 또는 git bash 실행한 후 clone 된 지역 저장소 folder로 이동 (예를 들어 cd User/Documents/Solmech/)
Start cmd or git bash and change working folder to the cloned folder (e.g. cd User/Documents/Solmech/)
cmd 또는 git bash 에서 각각 cd 또는 pwd 로 clone 된 folder 인지 확인
Check location using cd or pwd in cmd or git bash
jupyter notebook 실행
Run jupyter notebook

Good way to initialize `plt.Axes()`

For example, ax.arrow() may use plt.Axes
Good way to initialize? plt.axes() ? plt.gca() ?

How to cache `brew`?

If using brew for osx, how to cache?
Would it make cache larger? (pip alone 500MB)

import sympy as sy
a, b, c =  sy.symbols('a[m] b[kg] c[N]', real=True)

`os.path.dirname` or `os.path.basename` instead of `os.path.split` when possible

os.path.dirname or os.path.basename instead of os.path.split when possible
os.path.split(__file__)[0] → os.path.dirname()
os.path.split(__file__)[-1] → os.path.basename()

And use f-strings
Also think about reducing the number of tests
Could use matrix of .travis.yml
Along with #28

pip attempt / environment setting up faster but code running slower

How to make code run faster?
#28

Current status

According to the conclusion of Schuchert10 min seems to be a good goal
On a desktop, running the test takes less than 5 min
On Travis-CI, one job on linux or osx takes less than 10 min but on windows more than 20 min

platform	without cache	with cache
`linux`	20 min	10 min
`osx`	20 min	10 min
`windows`	25 min	50 min

Total 4:19:51 (1:14:47 by parallel)
Maybe 7.5 times time saving desirable
Also, cache size is quite big (~ 6GB)
Is docker a practical solution?

Too many environments?

Currently running on {linux, osx, windows} × python {3.5, 3.6, 3.7, 3.71, nightly}
Total 15 combinations
Reduce to a smaller number?
Run on osx & windows only?
Run on two last releases of Anaconda?
Recently, the Anaconda installation included some confusions

Docker

Could be faster
Need authentication settings or open the container

jobs.<>.steps.run.bash

want to remove bash from run: bash <script file name>
doc seems saying jobs.<>.steps.run.bash but the exact phrase not clear yet
https://github.com/actions/migrate/blob/master/azure-pipelines.yml implies use of jobs.<>.steps.bash but not documented

Google CoLab Compatible?

https://colab.research.google.com/

Can read ipynb files directly from a public repository of the Github

Importing a local py file may not go as smoothly

Any other issues?
