맥에서는 sasm 설치가 어렵다고해서 버추얼박스로 우분투설치해서 학습진행

20.04lts버전(현 최신 안정화버전) 으로 설치하였는데

도서에서는 18.0.4 버전으로 하고있다....

별 생각없이 다운로드했는데 sasm버전에서 부터 막힘. 아마 지원최신 버전이 19버전까지인것으로 보인다.

1일차에서 진행하다가 제대로 안되면 18버전으로 다시 설치해서 진행해볼 예정

환경 설치부분 입력하는 명령어.

sudo apt-get update

sudo apt-get -f install

sudo apt-get install nasm

sudo apt-get install gcc-multilib

sudo apt - fix-broken install

sudo apt-get install qt4-default

sudo dpkg -i sasm_3.9.0_amd64.deb

문제발생

19page,

sudo apt - fix-broken install 이라고 적힌 부분이 없는 명령어라고 뜸

검색해보니 sudo apt --fix-borken install 로 추측됨

검색시 깨진 의존성 문제를 해결할때 쓴다는데 ide설치하는데 왜 이런게필요할지 모르겠음. 일단 변경한 부분으로 진행

sudo apt-get install qt4-default 에서 문제발생

Package qt4-default is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'qt4-default' has no installation candidate

최신버전의 우분투를 설치해서 그런건가 그래서

qt5-default를 설치해봄

qt4에 있는 라이브러리를 사용할거라서 설치한것일거 같은데

qt5를 설치해도 될지는 의문

20page

sudo dpkg -i sasm_3.9.0_amd64.deb 부분에서 오류 발생

가장 최신버전으로 sudo dpkg -i sasm_3.11.1_amd64.deb로 실행했음.

sasm depends on libqt4-network (>= 4:4.7.0); however:
Package libqt4-network is not installed.
sasm depends on libqtcore4 (>= 4:4.7.0); however:
Package libqtcore4 is not installed.
sasm depends on libqtgui4 (>= 4:4.8.0); however:
Package libqtgui4 is not installed.

qt4-default 를 설치하지않아 발생한 문제로 예상중.....;;

qt4-default는 설치하지 못해서 그냥 없다고 말하는 라이브러리를 하나하나 설치해볼 예정

설치가 같은 내용으로 설치가 안됨

의존성 문제 해결이라고 부분을 다시 입력해봄

sudo apt -f install

뭔가 고쳐지는듯 보이나 여전히 설치가 안됨

qt4-default를 설치해보는 방안을 찾는중

sudo apt-add-repository ppa:rock-core/qt4

sudo apt update

sudo apt install qt4-default

로 진행하라는 글을발견

qt4-default가 설치가 된듯 보이나 sudo apt --fix-broken install을 입력하라는 경고가 뜸

진행.

여전히 sudo dpkg -i sasm_3.11.1_amd64.deb 가 안됨.

우분투 18.04버전을 다운로드 걸어놓고 내일 재 진행 예정

Swift 커스텀 키보드 진행과 한글 자음/모음 조합

2020. 5. 30. 23:32

요즘 노는 시간 도중도중 공부를 하고있는데

그 공부하고있는것중 ios용 키보드를 하나 만들고있다.

이곳에 쏟아 붇는시간이 얼마되지않아 진도가 많이 느리고

처음에 제대로 공부하고 계획짜서 시작한게아니라 벌써 2번이나 갈아엎은 프로젝트이다.

기록을 살펴보니 최초일자가 5월19일

시작날짜만 보면 근 11일정도하고 영문키보드까진 됐는데

만들어야지 하고 이글 저글 스크랩만 해뒀던게 5월초부터니

근 한달간 공부는 키보드관련만 하고있었다

그렇게 근 한달정도된 프로젝트 진행 소스는 아래에 있다.

키보드 디자인은 최대한 기본 키보드UI에서 벗어나질 않으려고 했고

기본 키보드를 쓰면서 제일 불편했던 숫자부분과 특수문자부분을 바로 입력가능하도록한 프로젝트였으나

여기까지 만들어놓고보니

한글을 입력하면!

자음, 모음이 하나씩 들어간다

합쳐지질 않는다

몰랐다.

새로운걸 알게되서 좋긴하나

어떻게 해야할지 모르겠다

조합하는거 자체는 어느 고마우신분이 c#으로 작성해둔게 있어서 Swift 소스로 바꿨는데

이걸 어떻게 입력이 들어가야할지 막막해져서

원래는 완성되면 올리려고한 포스트를 진행상황과 자모 합하는 함수 저장용으로 이 포스트를 남긴다.

아래 주소는 네이버 닉 골드러쉬님이 c#으로 12년도에 작성한 포스트이다.

이걸 swift로 변환하면 이렇게된다.

let cho:[Character] = ["ㄱ","ㄲ","ㄴ","ㄷ","ㄸ","ㄹ","ㅁ","ㅂ","ㅃ","ㅅ","ㅆ","ㅇ","ㅈ","ㅉ","ㅊ","ㅋ","ㅌ","ㅍ","ㅎ"]

let jung:[Character] = ["ㅏ", "ㅐ", "ㅑ", "ㅒ", "ㅓ", "ㅔ", "ㅕ", "ㅖ", "ㅗ", "ㅘ", "ㅙ", "ㅚ", "ㅛ", "ㅜ", "ㅝ",
                        "ㅞ", "ㅟ", "ㅠ", "ㅡ", "ㅢ", "ㅣ"]
let jong:[Character] = [" ", "ㄱ", "ㄲ", "ㄳ", "ㄴ", "ㄵ", "ㄶ", "ㄷ", "ㄹ", "ㄺ", "ㄻ", "ㄼ", "ㄽ", "ㄾ", "ㄿ",
                        "ㅀ", "ㅁ", "ㅂ", "ㅄ", "ㅅ", "ㅆ", "ㅇ", "ㅈ", "ㅊ", "ㅋ", "ㅌ", "ㅍ", "ㅎ"]
func hangle(c1:Character,c2:Character,c3:Character) -> Character? {
    var cho_i = 0
    var jung_i = 0
    var jong_i = 0
    for i in 0 ..< cho.count {
        if cho[i] == c1 { cho_i = i }
    }
    
    for i in 0 ..< jung.count {
        if jung[i] == c2 { jung_i = i }
    }
    
    for i in 0 ..< jong.count {
        if jong[i] == c3 { jong_i = i }
    }
    
    let uniValue:Int = (cho_i * 21 * 28) + (jung_i * 28) + (jong_i) + 0xAC00;
    if let uni = Unicode.Scalar(uniValue) {
        return Character(uni)
    }
    
    return nil
}

정확히 말하면 조금 변경했는데

변환이 안됐을때의 값을 nil값이 나오도록했고, 초성/중성/종성이 담긴 배열은 그냥 밖으로 빼버렸다.

분명 코드값 비교해가며 고민하신 소스일텐데 이렇게 공유해주시니 매우 감사할따름

시프트 연산 오랜만에 하네요.

솔직히 잘 기억도 안납니다.

저는 국딩이 아닙니다. 제 나이때 주변 애들은 전부 정보교육?인가 해서 한참 교과목으로 컴퓨터를 배우던때가 있습니다.

아 그리운 플로피디스크여~

아무튼 그때 교산지 강산지, 선생님의 왈 " 컴퓨터는 덧셈밖에못하는 바보야! "

그리고 시간이 흘러

저의 왈 " 선생님! 바보! "

컴퓨터는 곱셈연산, 그러니까 2진수의 시프트 연산으로 사람이 하는 곱셈과 유사한일을 할 수 있습니다.

주의점은 나열된 1과 0을 그대로 오른쪽 왼쪽으로 움직이는거라 예상치 못한 동작을 하기도합니다.

뭐 이런건 따로 검색해보세요

꽤나 덧셈 뺄셈 곱셈 나눗셈 연산을 재미지게 합니다.

기본적으로 C를 기반으로 작성된 문제이기때문에 이대로 가다보면 매크로연산정의하는 문제도 나오지않을까합니다.

아 그런거 싫은데

bool형 변수는 사실 0 과 1 이다! 라는걸 보여주려는 문제인거같은데

JAVA에서 bool을 바로 정수형으로 보여주기가 어찌해야할지 모르겠어서 결국그냥 1,0을 써서 출력했네요.

swift 는 c베이스로 만들어진거라 바로 bool을 int로 변형이 가능했습니다.

iOS 개발 튜토리얼4 - Chart(선 그래프) 사용

2020. 5. 11. 10:10

이번에는 iOS에서 차트로 유명한 오픈소스인 Charts를 사용합니다.

퇴사하고나면 행복해하면서 천천히 다음직장을 찾을줄 알았는데

하루하루 게임으로 현실도피하기 바쁨니다.

공부용 서적을 엄청 사놨는데 거의 안봤네요

튜토리얼용 영상도 거의 하루꼴로 찍어 올려볼생각이였는데 왜 이렇게 됐을까요.

iOS는 거의 모든걸 인터넷으로 배웠기에 은혜를 값는 셈으로 나도 다르분이 참고할 만한걸 만들고 싶었는데....

~~아무튼 영상은 아직 유튜브에서 영상처리로 업로드중이라 추후 수정으로 이글에 올릴 예정입니다.~~

영상 추가해보니 이 짧은내용을 5시간반정도 했네요..;;

한두달 안하다가 뭔가 하려니 이리도 버벅이게되네요

다음 편은 포폴용으로 토이프로젝트만들어볼 생각입니다.

했던건 튜토리얼1~4에 나왔던거랑 크게 다르지않을거같습니다.

메모앱을 만들생각이라....

서버연동으로 구글메모장 처럼

동기화가능하게 만들생각입니다.

계정도 엮어서 해봐야지

Flask 로 api 간단히 만들기 라는 글좀 따라해보다가 어디선가 긁어와서 살짝 수정해서 썻던 소스인데 기억이 안나서 출처는 없습니다.

init쪽에 conn이랑 curs생성하지않고( 해당 소스 지우고 )

클래스 만들어서 사용할때 crate_connect()호출해서 쓰는게 더 나아보이는데

여러모로 귀찮아서.. 그냥 집어넣었던거 같기도하고 애초에 있던거같기도하고

기억이 여로모로 애매하네요

mysql, 사용자 목록보기, 계정 생성, 권한 추가, 계정 삭제

2020. 5. 2. 05:05

MariaDb,

관리자 계정으로 들어간다.

# 사용자 목록 확인

우선 사용자 목록을 확인해보자

전체적인 정보가 담겨있는 데이터베이스를 봐야하니

mysql db로 들어가자

user mysql;

이미 있는 계정이 궁굼하면

이 mysql db에 들어가있는 상태에서

select host, user from user;

라고 쿼리를 입력하면 아래와같이 호스트 / 아이디 로 나온다

# 사용자 생성

이제 id 는 test_id 접속 호스트는 localhost 비밀번호는 1234 로 계정을 생성해 준다하면

create user 'test_id'@'localhost' identified by '1234';

라고 입력하고 쿼리 ok가 나오면 성공이다

다시 목록을 확인해보면

아까 6개였던 표에서 7개줄로 변경되고 중간에 Localhost 에 test_id로 추가가되어있음을 확인 할 수 있다.

# 사용자 계정에 권한 추가하기

계정을 생성해봤자 사실 이 시점에서는 아무것도 못한다.

그래서 계정에 할 수 있는 것에 대해 정의를 해줘야하는데

이때 권한을 어떠한 db에 대해 권한을 정의해준다.

테스트용도로 wiwi_blog_test 라는이름의 db를 미리 만들어주었고

이 db에 아까 만든 test_id계정의 권한을 주자

주려는 권한은

select, insert, update, delete

이 네가지를 준다고하면

grant select, insert, update, delete on wiwi_blog_test.* to 'test_id'@'localhost';

※ db명 뒤의(wiwi_blog_test의 뒤) 점(.) 하고 * 는 이 db에 있는 모든 테이블을 지칭한다.

쿼리입력후 쿼리 Ok가 뜨면 성공이다.

필요에따라 저 네개중 빼고 줄 수도 있다.

사실 이대로 접속해보려면 제대로 접속이 안된다.

이 권한변경에 대해 적용을 한다는 쿼리를 날려줘야한다( insert 후의 commit과 같은)

flush privileges;

이제 test_id로 wiwi_blog_test db의 검색,입력,수정,삭제를 할 수 있게 되었다!

localhost로 주었기에 물론 외부에서는 접속이 안된다. 하지만 이제 다른 db관리 프로그램으로 해당 db에 접근 할 수 있게 되어 gui환경으로도 편집 수정 확인을 할 수 있다!

# 사용자 계정에 주어진 권한 확인

제대로 권한이 들어갔는지 권한 확인을 하자면

show grants for 'test_id'@'locahost';

wiwi_blog_test db의 모든 테이블에 대해 select, insert, update, delete가 되어있다고 잘 나온다 ㅎ

# 계정 삭제

이제 이 계정을 삭제해보자

drop user 'test_id'@'localhost';

역시 query ok가 뜬다면 성공한것이다

mysql, 사용자 비밀번호 수정하는 방법

2020. 5. 2. 03:17

어느순간부터 mysql에서 수정시 update 문으로 user테이블 수정으로 비밀번호 수정이 안된다.

update user set password='user_id'@'host' identified by 'new_pw'

입력시

COLUMN PASSWORD IS NOT UPDATEABLE 이라고 경고문이 뜬다.

기존 id가 wiwi이고 접속 호스트가 localhost 라면 이 계정의 비밀번호를 abcd1234로 변경한다하면

아래와 같이 하면된다.

우선 데이터베이스는 기존과같다.

root계정으로 접속한후

use mysql;

alter user 'wiwi'@'localhost' identified by 'abcd1234';

query ok 라고뜨면 끝이다 간단!
