NMEA / GPS 날짜&시간

epoch로 계산해야 하는줄 알았는데 자릿수가 적어서 고민때리다가 발견

그냥 두자리씩 자르면 된다 -_-

GPGGA는 위치와 시간 정보가 들어있는 녀석인데

011557.00은 시간으로

01:15:57.00 UTC (KST는 +9니까 한국은 10시)

261020은 날짜로

DD/MM/YY

26/10/20 -> 2020년 10월 26일 로 출력된다.

마지막의 CRC만 계산하는 법 찾으면 그냥 라이브러리 만들어서 쓰는게 편할지도?

$GPGGA,011557.00,3724.048737,N,12659.412849,E,1,27,0.3,90.1,M,18.4,M,,*5E

for example:

$GPRMC,040302.00,A,3209.992,N,11052.530,W,0.00,93.70, 070807,11.30,E*7C

I would extract 040302.00 and 070907 and converted to milliseconds of the week (0000 SUnday GMT).

Tuesday August 07, 2007 04:03:02.00 AM UTC would equal to: 187,382,000 milliseconds

온프레미스

on premise 건물내에 있는?

AWS 책 보다 보니 온프레미스 라는 말이 나와서 뒤적뒤적.

그냥 사전적으로는

전제, 부동산, 토지 등의 의미를 지니는데 on~ 이니까 토지내에 있는

즉, 건물에 포함된 전산실을 의미하는 듯

NMEA로 검색하니 GPS raw 데이터를 받을수 있는 어플들이 있어서

회사 옥상 한바퀴 돌면서 저장하고 간략하게 분석중

$GPGGA 가 위치 정보로 얼마나 자주 읽냐를 설정을 해주어야 겠지만 갤럭시 S7에서는 1초에 1번으로 해둔듯.

1걸음에 1초 해서 약 10걸음 걷고 저장하고 반복했는데 10~12번 정도 나타난다.

위성항법으로 GPS / GLONASS / Beidou(나무위키에만) 가능하다고 되어있는데

그래서 그런가 GP 외에도 GL(글로나스?) BD(베이두) 로 시작하는 녀석들이 보이긴한다.

일단 내가 원하는건 GPS 정보니까 $GP 로 시작하는 것 들 중에 위치 정보인 $GPGGA 를 찾으면 된다~ 라는 것

FFT와 고조파(harmonic)

그러니까 얘를 줄일수 있는거야 없는거야?

있으면 어떻게 판단해야 하는거야? ㅠㅠ

NUMA, SMP

numatool 이라는걸 알아가게 되네..

NUMA는 복수개의 CPU를 사용할 때 버스를 통해서 메모리를 공유하고

SMP는 개별 CPU에 메모리를 달아 다른 CPU를 통해 메모리를 접근하는 방식으로 보임

(그러고 보니 펜3 시절에 SMP 라고 들은거 같은데 그때랑 지금의 2cpu 는 방식이 다른가?)

Audio Induction Loop

인덕션이라길래 그 전기레인지 상상했는데 오디오랑 도대체 어떻게 연결이 되나 했더니

한줄 요약하면 인공와우 혹은 보청기 사용자를(청각 장애인) 위한 전용 스피커 정도로 하면 될 듯

induction을 통해 코일에 직접적으로 음파를 전달하는걸로 보면 될것 같기도 하지만.. 내 영역 밖의 이야기.. ㅠㅠ
