kinetics 인줄 알았는데 kinematics 군..

결국은 systemd에 등록인데..
python 프로그램의 경우 pip -g로 인스톨 해서 전역으로 하지 않으면
대부분(?) 에러가 나던데.. 그건 언급이 없네
| cd /lib/systemd/system/ sudo nano hello.service The service definition must be on the /lib/systemd/system folder. Our service is going to be called "hello.service": [Unit] Description=Hello World After=multi-user.target [Service] Type=simple ExecStart=/usr/bin/python /home/pi/hello_world.py Restart=on-abort [Install] WantedBy=multi-user.target Here we are creating a very simple service that runs our hello_world script and if by any means is aborted is going to be restarted automatically. You can check more on service's options in the next wiki: https://wiki.archlinux.org/index.php/systemd. Now that we have our service we need to activate it: sudo chmod 644 /lib/systemd/system/hello.service chmod +x /home/pi/hello_world.py sudo systemctl daemon-reload sudo systemctl enable hello.service sudo systemctl start hello.service |

| $ man pax11publish pax11publish(1) General Commands Manual pax11publish(1) NAME pax11publish - PulseAudio X11 Credential Utility SYNOPSIS pax11publish -h pax11publish [options] [-d] pax11publish [options] -e pax11publish [options] -i pax11publish [options] -r DESCRIPTION The pax11publish utility can be used to dump or manipulate the PulseAu‐ dio server credentials that can be stored as properties on the X11 root window. Please note that the loadable module module-x11-publish exports the same information directly from the PulseAudio sound server, and should in most cases be used in preference over this tool. Use the following command to dump the raw PulseAudio-specific data that is stored in your X11 root window: xprop -root | grep ^PULSE_ OPTIONS -h Show help. -d Read the PulseAudio server credentials currently set on the X11 root window and dump them in a human readable form. This reads the PULSE_SERVER, PULSE_SINK, PULSE_SOURCE and PULSE_COOKIE properties. -i Similar to -d, however dumps them in a Bourne shell compatible format so they may be used together with the eval shell command to set the $PULSE_SERVER, $PULSE_SINK, $PULSE_SOURCE environment variables. Also reads the authentication cookie from the root window and stores it in ~/.config/pulse/cookie. -e Export the currently locally used sound server, sink, source configuration to the X11 root window. This takes the data from the $PULSE_SERVER, $PULSE_SINK, $PULSE_SOURCE environment vari‐ ables and combines them with the data from ~/.con‐ fig/pulse/client.conf (or /etc/pulse/client.conf if that file does not exist). If specific options are passed on the command line (-S, -O, -I, -c, see below), they take precedence. Also up‐ loads the local authentication cookie ~/.config/pulse/cookie to the X11 server. -r Removes the configured PulseAudio configuration from the X11 root window. -D DISPLAY Connect to the specified X11 display, instead of the default one configured in $DISPLAY. -S SERVER Only valid for -e: export the specified PulseAudio server as de‐ fault to the X11 display instead of the one configured via local configuration. -O SINK Only valid for -e: export the specified sink as default sink to the X11 display instead of the one configured via local configu‐ ration. -I SOURCE Only valid for -e: export the specified source as default to the X11 display instead of the one configured via local configura‐ tion. -c FILE Only valid for -e: export the PulseAudio authentication cookie stored in the specified file to the X11 display instead of the one stored in ~/.config/pulse/cookie.

다운로드 받은걸 가져와서 회전하려니까
이상한 곳에서 회전되는데 도무지 삭제가 되지 않는 커서도 아닌 무언가가 있어서 찾아보니
origin 인듯.
아무튼 오리진을 도형(?)의 중심으로 옮기는건 우클릭 - Set Origin - Origin to Geometry 해주면 된다.
| Type Geometry to Origin Moves the model to the origin and this way the origin of the object will also be at the center of the object. Origin to Geometry Moves the origin to the center of the object. Origin to 3D Cursor Moves the origin of the model to the position of the 3D cursor. Origin to Center of Mass Moves the origin to the calculated center of mass of model (assuming the mesh has a uniform density). Center Median Point Center, Bounding Box Center |

커서는 마음대로 옮길수 있으니 커서로 오리진을 이동시키는 듯.

그 와중에 HIL 테스트 이런게 보여서 검색해보니, MBD(Model Based Design)에서 나오는 테스트 방법론(?)인가 보다.
