이마트 트레이더스 가서 사온 선풍기
근데.. 지상용 BLDC 선풍기가 있다면..
해상용 / 지하용 / 심해용 / 우주용 / 공중용 있는거냐 -ㅁ-??
영어로는 깔끔(?) 하게 BLDC 전기 선풍기라면서 왜 뜬금없이 -ㅁ-????

카메라가 위치 잘못 조정되었는지 이상하게 나오긴 했는데
아무튼 이렇게 렌더도 가능하다.
특이한건.. gui 로는 보이지도 않고 수행된다는 점.
test.blend 열어보니 기본 카메라가 있는데 또 추가해서 이상하게 보이는 느낌
blend 파일을 읽어서
저장할 경로를 지정하고

사람을 예를 들어 무릎은 앞쪽으로 구부러지지 않는데
그러한 제약조건을 걸어주려고 찾는 중.
스샷은 요즘껀데. 동영상은 옛날꺼. 그럼 변한게 별로 없으려나?

pose mode 에서 shift-i 혹은 pose - inverse kinematics - add ik to bone을 해준다.
일단 pose mode로 오면 프로퍼티에 bone이 생기긴 한다.
여기서 하는거랑 차이가 있는진 모르겠다.

| $ mosquitto_pub --help mosquitto_pub is a simple mqtt client that will publish a message on a single topic and exit. mosquitto_pub version 2.0.11 running on libmosquitto 2.0.11. Usage: mosquitto_pub {[-h host] [--unix path] [-p port] [-u username] [-P password] -t topic | -L URL} {-f file | -l | -n | -m message} [-c] [-k keepalive] [-q qos] [-r] [--repeat N] [--repeat-delay time] [-x session-expiry] [-A bind_address] [--nodelay] [-i id] [-I id_prefix] [-d] [--quiet] [-M max_inflight] [-u username [-P password]] [--will-topic [--will-payload payload] [--will-qos qos] [--will-retain]] [{--cafile file | --capath dir} [--cert file] [--key file] [--ciphers ciphers] [--insecure] [--tls-alpn protocol] [--tls-engine engine] [--keyform keyform] [--tls-engine-kpass-sha1]] [--tls-use-os-certs] [--psk hex-key --psk-identity identity [--ciphers ciphers]] [--proxy socks-url] [--property command identifier value] [-D command identifier value] mosquitto_pub --help -A : bind the outgoing socket to this host/ip address. Use to control which interface the client communicates over. -d : enable debug messages. -c : disable clean session/enable persistent client mode When this argument is used, the broker will be instructed not to clean existing sessions for the same client id when the client connects, and sessions will never expire when the client disconnects. MQTT v5 clients can change their session expiry interval with the -x argument. -D : Define MQTT v5 properties. See the documentation for more details. -f : send the contents of a file as the message. -h : mqtt host to connect to. Defaults to localhost. -i : id to use for this client. Defaults to mosquitto_pub_ appended with the process id. -I : define the client id as id_prefix appended with the process id. Useful for when the broker is using the clientid_prefixes option. -k : keep alive in seconds for this client. Defaults to 60. -L : specify user, password, hostname, port and topic as a URL in the form: mqtt(s)://[username[:password]@]host[:port]/topic -l : read messages from stdin, sending a separate message for each line. -m : message payload to send. -M : the maximum inflight messages for QoS 1/2.. -n : send a null (zero length) message. -p : network port to connect to. Defaults to 1883 for plain MQTT and 8883 for MQTT over TLS. -P : provide a password -q : quality of service level to use for all messages. Defaults to 0. -r : message should be retained. -s : read message from stdin, sending the entire input as a message. -t : mqtt topic to publish to. -u : provide a username -V : specify the version of the MQTT protocol to use when connecting. Can be mqttv5, mqttv311 or mqttv31. Defaults to mqttv311. -x : Set the session-expiry-interval property on the CONNECT packet. Applies to MQTT v5 clients only. Set to 0-4294967294 to specify the session will expire in that many seconds after the client disconnects, or use -1, 4294967295, or ∞ for a session that does not expire. Defaults to -1 if -c is also given, or 0 if -c not given. --help : display this message. --nodelay : disable Nagle's algorithm, to reduce socket sending latency at the possible expense of more packets being sent. --quiet : don't print error messages. --repeat : if publish mode is -f, -m, or -s, then repeat the publish N times. --repeat-delay : if using --repeat, wait time seconds between publishes. Defaults to 0. --unix : connect to a broker through a unix domain socket instead of a TCP socket, e.g. /tmp/mosquitto.sock --will-payload : payload for the client Will, which is sent by the broker in case of unexpected disconnection. If not given and will-topic is set, a zero length message will be sent. --will-qos : QoS level for the client Will. --will-retain : if given, make the client Will retained. --will-topic : the topic on which to publish the client Will. --cafile : path to a file containing trusted CA certificates to enable encrypted communication. --capath : path to a directory containing trusted CA certificates to enable encrypted communication. --cert : client certificate for authentication, if required by server. --key : client private key for authentication, if required by server. --keyform : keyfile type, can be either "pem" or "engine". --ciphers : openssl compatible list of TLS ciphers to support. --tls-version : TLS protocol version, can be one of tlsv1.3 tlsv1.2 or tlsv1.1. Defaults to tlsv1.2 if available. --insecure : do not check that the server certificate hostname matches the remote hostname. Using this option means that you cannot be sure that the remote host is the server you wish to connect to and so is insecure. Do not use this option in a production environment. --tls-engine : If set, enables the use of a TLS engine device. --tls-engine-kpass-sha1 : SHA1 of the key password to be used with the selected SSL engine. --tls-use-os-certs : Load and trust OS provided CA certificates. --psk : pre-shared-key in hexadecimal (no leading 0x) to enable TLS-PSK mode. --psk-identity : client identity string for TLS-PSK mode. --proxy : SOCKS5 proxy URL of the form: socks5h://[username[:password]@]hostname[:port] Only "none" and "username" authentication is supported. See https://mosquitto.org/ for more information. |

22.04
2760p 에서 부팅 잘됨.(uefi가 제한적으로 제공되는 녀석)
24.04
flag를 인식못하는지 bios_grub 쪽으로 켜졌다가 점프해야 할 것 같은데 부팅이 안된다.
도대체 몇번을 깔고 쑈하는지 쩝.
웃긴건 22.04 깔고 24.05로 distupgrade 하면 잘 된다는 것. 멀까..?
ESP - EFI (Extensible Firmware Interface) system partition
에는 부팅시 로드할 파일들이 있는데. UEFI에 다 올려져 있다면 파티션이 필요 없겠지만
지원이 미비한 보드의 경우 로드할 파일이 없으니 못켜지는걸려나?
