2023 Q4 Summary​

Divide and Conquer.

• 퇴사 후 약 4개월 간 영어에 전념할 수 있었다.
• 한달동안 텝스한다고 삽질했던 것만 빼면 3개월간 아이엘츠를 공부하며 영어에만 몰두할 수 있었고, 정규반을 마친 뒤에는 영어 말하기,쓰기까지 커버가 되었다.
• 물론 아카데믹 스피킹, 라이팅을 잘 하는 건 추가로 1-2개월 더 해야하지만, 이제 이 지긋지긋한 영어라는 걸 프로그래밍언어를 공부하듯 어떻게 공부하는지 깨달아서 크게 문제가 되진 않을 것 같다.
• 모의고사에선 스피킹,라이팅 모두 6이 안정적으로 나왔고, 이제 기출을 돌릴 수 있다는 자신감이 생겼다.
• 어느정도 언어장벽이 사라지니 새로운 경험들도 할 수 있게 되었는데, devto나 hackernews 블로그 글들을 보면 이 사람이 아카데믹 라이팅을 한 사람인지, 고딩수준(내수준)인지 바로 보인다.
• 컨퍼런스에서 말하는것도 비슷하다, 몇몇은 두서없이 말하고, 사티아나델라같은 사람은 분명히 건너올 때 아이엘츠를 땄을 것 같다. 요즘엔 막연한 꿈이 feasible한 꿈이 되었기에, 두 페이지가 되는 지문을 봐도 그렇게 힘들지는 않다. 그리고 아무도 겪어보지 못한 페이즈로 접어들고 있는 국가에 대한 의존성을 분리할 수 있기에 가장으로서의 걱정도 사라졌다.
• 한편, 동기의 시간을 잠깐 뺏어 서로의 히스토리를 공유할 수 있었는데, 그의 가치관이 나와 비슷해서 너무 재밌었다. 나보다 똑똑한 사람이 나랑 똑같은 생각을 하고 있다는게 방향성을 잘 잡았다는 반증같아서 그랬다.
• 의료업계는 미국가면 4억부터 팔린다는 걸 듣고, 간호사분들이 왜 몇몇 있었는지, 간호사 증명하면 학원에서 할인을 해주는지 알 것 같았다.
• 면접도 걱정보단 잘 진행되어 최종 단계까지 오게되었다. 역시 인터뷰는 가벼운 마음으로 본 것들이 합격률이 좋다. 여기엔 일요일마다 3-4시간씩 코딩을 꾸준히 집중해서 했던 게 주효했다.
• 기술자는 주방장이 칼을 가는 것 마냥 계속 단련이 되어있어야하지만, 회사는 여러가지를 아울러 일하는 Problem solver 를 좋아한다, 그렇지만 회사가 좋아하는 인재가 되는거지, 시장에서의 상품가치는 점점 떨어진다. 다시 "내 코드가 상품성이 있어졌다" 라는 게 검증되었으니, 이제 회사에 대한 의존성을 분리하는 일만 남았다. 그 답은 PE가 되는 것이였고, 어떻게 공부하는지 알았기에 시간만 쏟으면 달성할 수 있는 목표가 되었다.
• 메모어 이전엔 달마다 회고를 했었다. 13기를 끝내니 주차단위 회고가 세부 계획을 미세조정하는데에 장점이 더 있었다.
• 개인 일에도 지라를 썼었는데, 생각보다 태스크 생성, 워크 로깅에 시간이 많이 들어간다, 금/토요일 사이, 일/월 사이로 루틴을 잡는게 집중이 분산되지 않아 좋았다.
• 최근엔 같은 MBTI인 분을 만나게되어 "님 제 성격이시면 업무적이 아닌 개인적으로도 회고하시죠?" 라고 했더니 "네 달마다해요" 라길래 그 분에게도 여기오면 재밌을거라고 추천했는데, 올 지는 잘 모르겠다.

• Problem
  • 스피킹 Part2 노트테이킹 방법이 선생님들마다 조금씩 다른데, 템플릿을 이미 예전 선생님걸로 외워버려서 연습해가지고 걱정됨.
  • 스터디 신청을 했으나 단어 오답 수로 벌금차감을 한다는 소문을 들어 걱정됨. 10대 친구들만 없으면 좋겠음 머리로 못 따라가니까.
    • 이젠 이해가 안 되는데 강제로 뭔가를 머리에 넣는게 힘듦.
  • 라이팅 브레인스토밍도 만만치 않음, 주장-근거-부연설명으로 가는 플로우가 창작의 영역이라 인풋-아웃풋만 하던 나한텐 너무 어렵다.
    • GPT의 도움을 받긴하는데 이걸 계속 이렇게 해도 되는건지 잘 모르겠다.
    • 가끔 번뜩 떠오르는 아이디어는 내 수준에서 영어로 옮길 수 없는 어려운 한국단어들 뿐이다.
  • Computer based vs Paper based 의 차이가 고민되어 국내외 영상들을 찾아보고 나름대로 정리하는데 시간을 좀 뺏김 (2h)
  • 캠브릿지10 책 중고로 찾는데 시간을 좀 허비했다. 근데 캠브릿지10 PDF랑 음원이랑 다 인터넷에 돌아녔다.. 미리 좀 알았으면 (2h)

  • 일단 신청을 했고 오늘자로 신청한사람이 많이 없다고하니까.. 미리 걱정하지 말기
  • 이건 많이 접해봐야 되는건지 감도 안 온다. 다음 주 초까지 이상태면 질문메일 보내보기로.. 물론 "많이 접해봐야된다"가 답일 것 같긴하지만...
  • Computer based 로 마음을 정했다. 가장 큰 이유는 라이팅 때문
    • 영타 300타 이상 나오니까 필기로 썼다지웠다가 할바에 이게 더 효율적일 것 같았음.
    • 리딩은 가독성이 이슈라고 하는데, 맨날 보던게 개발 공식 문서들이니 어느정도 괜찮을 것 같았고..
    • 리스닝은 헤드셋을 착용할 수 있다고해서 다른사람 종이넘기는 제스쳐에 집중이 안 흐트러질것 같았음.
    • 게다가 앉아서 숙인 다음에 3시간을 버틸 허리가 아니니까 어쩔 수 없을듯.
• 자주보는 채널인 쿠르츠게작트에 왜 한국이 죽어가는가에 대한 영상이 올라왔다.
  • 한국인들 베댓이 많이 보이는데, 다들 같은 사회상을 걱정하고 있는 것 같아 영어공부 동기부여 짤이 하나 더 추가되었다.

  • 아이엘츠 중급반 숙제 잘 따라가기
  • 리스닝, 리딩은 감 떨어지지 않게 하루 한 지문이라도 꾸준히 풀기
  • 리딩은 확실히 지난주보다 좋아졌다. 세 가지 그룹 문제를 머리 속에 넣고, 숨은그림찾기하듯 각각의 키워드를 매칭시킨 뒤 앞뒤 주변을 읽어 패러프레이징한 단어들을 걸러내는 스킬이 필요한데 점차 나아지는 것 같다.
  • 정보처리기술사가 정보관리기술사로 바뀐 것도 모르고, 첫 수업을 들었는데 이건 CIO, CTO를 만들어주는 시험이란 생각이 들었다. 왜 회사에서 임원진으로 데려가는지 알 것 같았다.
  • 융합IT의 전반적인 걸 공부하고. 이걸로 면접 대비도 할 수 있을 것 같다.
  • 모든 토픽들에 대해 마인드맵을 만들고, 아이엘츠 라이팅/스피킹 공부하듯이 접근하면 언젠간 딸 수 있을 것 같다.
• Problem
  • 리스닝
    • 캠브릿지10 MP3이 더이상 캠브릿지 사이트에서 제공되지 않아서 2만원을 날린 느낌이였다, 그냥 유튜브에 있는걸로 풀걸
    • 캠브릿지10은 섹션3,4도 잘 들린다. 난이도가 시험보단 낮은거 같아 꾸준히 딕테이션과 쉐도잉을 하지만 효용성이 있을지 약간 의문스럽다. (아마 제너럴아이엘츠 수준인듯)
  • 라이팅
    • 알면 알수록 어렵다. 특히 부연설명을 위한 ,while V ,with O Ving 패턴은 이해는 되지만 어느 경우에 써야하는지 아직 감은 잘 안온다.
    • Part1 다이어그램 해석 지문은 Part2 의 주제별 브랜스토밍 후 글짓기를 하는 것보단 희망적이다. 하지만 아직 손에 익지는 않아 패턴들을 조합하는 중.
  • 스피킹
    • 스피킹은 기존 직장인2분말하기 책을 학원가는 도중에 쉐도잉하는데, 효용성이 크게 없는 것 같다.
    • 이것도 여러 문제 패턴들 중에서 정규화 된 답안을 내야하는데 그걸 연관되어 생각하는게 아직 힘들다. 예를들면 사람 -> 부모님 -> 사려깊은, 존경받는, 친구 -> 웃긴, 좋은 성격, 유명한사람 -> 개그맨 -> 웃긴, 모범이되는 이런 키워드들이 머리 속에 매핑이 되어있어야한다.
    • 필러를 쓸 수 있는 시험도 아니고, 막힘 없이 말해야하기 때문에 내 경험을 말하면 안 되지만 자꾸 경험을 떠오르게 된다.
  • 디스크 재활이 성공적으로 진행중인줄 알았는데 새로운 좌골 통증이 생겼다. 이런
• Try
  • 문맥상으로는 이해하지만 쉐도잉하면 못 기억하는 부/관사 때문이라도 일단은 꾸준히 해봐야할 것 같다. 하고 후회하는게 그 반대보단 낫겠지..
  • 라이팅 숙제는 잘 따라가고 있지만 커리큘럼이 끝났을 때 실제 지문들을 도전할 수 있을지 좀 두렵다. 근데 계속 꾸준히 해야한다.
  • 아이엘츠 아카데믹이 대학 입학을 할 수 있냐는 시험이니, 외노자가 되려면 대학생보단 영어를 잘해야지 않나 하는 마음에 하루에도 몇번씩 마음을 다잡는중..
  • C++보단 빠르게 마스터하겠지..
  • 스피킹
    • 이건 전략을 바꿔야할 것 같다. 기존 책에서 쌤의 베스트 답안을 다운받아서 들으면서 그 기준으로 계속 쉐도잉을 해야할 것 같다.
    • GPT와 대화하는 기능으로 아이엘츠 선생님 한명이 생겼는데 특정 주제의 질답을 하는 건 좋으나 여행영어 수준으로만 대화가 가능하다. 짜임새 있게, 정규화된 답변을 말하는건 스피킹 레벨을 한단계 올려야 가능하다. 하루종일 외국인 멘토가 붙어있는것도 아니니 일단 따라해야 체득이 되고 거기서 변화를 줘야할 것 같다.
    • 주제에 대해 키워드 맵을 만들어 나가고 있다. 아직 Part1만 진행중이라 주말에 Part2, 3에 대해도 매핑을 해놓고 녹음->딕테->수정을 반복하며 좀 더 입에 붙는 패턴들을 써야할듯하다.
    • 내 경험을 말하지 않는 연습을 어떻게 할 수 있을까? 예를들어 unusual meal 에 대해서 질문이 오면, 난 푸팟퐁커리가 생각나고 태국/게살/맛있음/비많이옴 하며 추억에 잠기면서 망해버린다.
    • 푸팟퐁커리 대신 김치라면/동네/인기음식점/K전통음식/unusual 한거잖아 라면에 김치 넣는게/Heavy meal but affordable/ 라고 1분안에 떠올라야 좋은 점수를 받을 수 있을 것 같다.
  • 주말 하루는 어깨만 대신 먹고, 많이 걷고 걸은만큼 쉬어줘야겠다. 80%정도 복구했다고 착각한듯. 여러모로 건강하지 못한 육체에 불안한 정신이 깃든 한 주

• Problem
  • 레퍼쳌 해드렸던 분이 원하시는 기업으로 잘 옮기셔서 저녁 접대를 받았는데, 오랫만에 새벽까지 술마시니 술 때문에 발이 저린건지 운동 때문에 저린건지 생활 패턴때문에 저린건지 통증 디버깅이 안되었다. 30분 투자한 것치고 넘 호사를 누린것 같기도 했다. 내가 외노자가 될 때 +82로 레퍼런스 번호 달아놓겠다고 했는데 그 이후 얼마나 해드려야할지 감이 안온다 :웃으며눈물을흘리는_얼굴:
  • 스피킹 수업시간에 짝지와 함께 질답을 하는 방식이 추가되었는데, 둘다 멘붕에 빠졌다. 아 그렇지~ 면서 하나씩 아이디어 추가하면서 질답하는데, 이게 맞는 방향인지 지금 생각해도 웃기다. 그래도 연습했던 문제들은 약간 편해졌다.
  • 기술사 숙제는 전자정부표준프로세스 전체를 요약하는 등의 서술형인데, 영어 공부때문에 언제 할 수 있을지 모르겠다. 벌써 3주차가 밀려서 하루는 족히 써야할텐데..
• Try
  • 다시 금주하고 이번주는 몸 컨디션을 체크하기
  • 멘붕에 빠질 시간이면 그냥 모범답안을 두 세번 따라 읽는걸로 전략을 바꿨다 녹음도 원테이크 말고 될때까지 5-10번 지금처럼 하고..
  • 리스닝 2h 리딩 1h 스피킹 2h 라이팅 2h + 수업 이 루틴을 일일퀘스트마냥 유지하자.
  • 이건 당장의 우선순위가 높지 않으니 개요랑 숙제 목록만 모아놓고, 지금처럼 이동시간에 강의만 듣는걸로..

  • 이제 정규반 갈 실력이 된것 같아서 기분 좋은 한주
  • 운동도 약하게 올렸더니 7.5/10 까지 다시 회복.
• Problem
  • 라이팅, 리스닝 패턴들 미숙한 거 연습으로 해결 필요
  • 이제 영어가 좀 보여서 생활계획표 원판을 완성할 수 있었는데, 생각보다 만족스런 앱이나 웹이 없었음.. 대충 planpapers 사이트에서 처리
  • 시험을 11월에 보려고했는데 아직은 실력이 안되어서 그걸론 취업연계 제출을 못하고 아무기업이나 이력서 하나 내고 증빙해야하는게 시간 뺏겨야해서 걱정.
• Try
  • 건강과 공부 사이클을 유지하면 될 것 같다. 추워지기전에 마무리하고 12월 시험 보는걸로!
  • 겨울엔 밋업 다니면서 영어 쓰고, 밀렸던 코딩들 하면서 영어면접 트러블슈팅할 생각에 벌써 기분좋다.

중급반 성료.

• 7월, 정규반에 갔다가 2주 만에 내가 있을 곳이 아니다 라고 판단해서 환불하고, 베이직 문법 책 정리하고, 1분 말하기 책부터 다시 리팩토링하고, 기본반 인터넷 강의로 베이직 교제 다 끝내고, 중급반에 오니까 쌤이 뭐라고 말하는지 좀 들렸다.
• 첫 주는 호기롭게, 둘째 주는 멘붕하고, 셋째 주는 그냥 하라는거나 잘해보고, 넷째 주에 오니 어? 이게 되네 가 되었다.
• 영어 일기 밖에 안 써봤던 K인재인 내가 뭐가 되었던 엣세이를 쓰고 1분30초 동안 발표한다니 놀랐다. (아직은 5.5수준이지만..)
• 이제 GPT가 뱉어내는 영어 산출에 오류들이 보이기 시작한다. 심지어 꽤 많다, 확률로 처리하기 때문인지 전반적인 시제 통일도 못 한다. 왜 통번역가분들이 아직은 GPT로 번역가를 대체할 수 없다라고 했는지도 알 것 같다.
• IELTS 를 유튜브에 검색하면 대부분 1달완성이라고 나오는걸 보고, 과대광고인지도 모르고 그래 이번 기회에 영어 좀 제발 끝내자, 어차피 잘하는 사람들 물어보면 한 번은 빡세게 했던 때가 있다니까 라며 호기롭게 도전을 선언했는데 지금와서 다시 그 영상들을 보니 애들 혀가 다 꼬여있었다.
• 프로그래밍에 비유한다면 2주 완성 정보처리기사나, 초봉 5,000만원 3개월 완성 국비지원과정일 것 같다.
• 정규반에 오니 K인재들은 거의 없고, 예전처럼 대부분이 유학파다,
• 머리가 더 굳기 전에 방향 전환을 해서 다행이다싶었지만, 하루에도 몇 번씩 한숨은 나온다. 오히려 개발할 때보다 샷건(?)도 많이 치는 것 같다.
• 프로그래밍에 대한 경로만 최적화 되어있는 뇌를 학습시키는게 쉽지 않다.
• 바깥 양반에게 양해를 구하고, 휴대폰에 데일리 퀘스트랑 사전, 녹음기, 엑셀, 뱅킹 빼고 메신저를 포함하여 다른 모든 앱을 삭제했다,
• 난 지인들에게 매번 공중전화쓰던 시절이 삶에 느림과 기다림이 있었던 시절이라고 말하고 다녔는데, (요즘엔 낭만이 있던 시절로도 불리는 듯)
• 공부를 핑계로 그 시절로 잠시 돌아갈 수 있어서 좋다. Digital Immigrant 이기에 어쩔 수 없나보다.

• Keep
  • 공부 사이클 유지
  • 일일퀘스트를 잘 달성하고 있다.
  • 바깥 분 출장으로 인해 달성이 가능했던건지, 아니면 스킬셋이 올라서 가능했던건지 이번주에 테스트해볼 수 있을듯.
  • Writing Part1 쓰는게 어느 정도 된다. 쓸데없이 패러프레이징 안하면 7.0부터 시작한다는 이야기에 모든 페러프레이징을 내려놓고 맞는/아는 것만 쓰기로 마음먹었다.
  • 언어능력은 얼마나 아느냐가 아니라 단어 뒤에 어떤 말이 올지 빠르게 가져다가 붙히는거라고 하는데, 이제 약간씩 되는 것 같다. 녹음하고, 원래 말하려던걸 체크하고, 오답노트하고 5번말하기 스텝으로 반복하면 효과가 많이 나올것 같다.
  • 운동 사이클 유지
  • 원인모를 왼발 통증으로 고생을 좀 했는데, 그 원인을 카프레이즈라고 생각해서 금요일에 스쿼트/불스스/카프레이즈 3단으로 조졌더니 오히려 풀렸다.
  • 재활 10개월차인 지금 두려움을 좀 버리고, 워밍업을 약간 덜하면서 루틴을 유지해야할 것 같다.
  • 노파심에 사용하고 있던 방석이 오히려 더 허리에 무리를 주고 있었다. 없앴더니 좀 더 편해졌다.
• Problem
  • 스피킹 시간이 쌤 건강 악화로 진행되지 못해서 개인적으론 약간 아쉬웠지만 많이 걱정되기도 했다. 저 사람은 10시간씩 일하면서 밤에는 학생들 첨삭까지 해줘야하는데, (첨엔 조교들이 할것 같기도 했는데 나중에 질문하면 다 기억하고 있다.)
    • 과연 언제 뇌가 쉴까? 나중에 스트레스 매니징을 어떻게 하는지 물어봐야겠다.
  • 라이팅 파트2 에세이 쓰는건 아직 배우지는 않았지만 어휘력이 딸려서 막연히 두렵다. 단어나 필수 표현들을 외워도 딱 그때 뿐이고 이걸 연결시켜야하는데, 뇌한테 "왜" 가 아닌 "어떻게" 라고 질문해도 뭐가 잘 붙지는 않는다. 담주엔 그 비법도 알게 되었으면...
  • 리스닝에 정체기가 왔다. 컨디션 좋을 떈 8도 나왔는데 요샌 7정도로밖에 못 듣는다. 갑자기 안들리는 것도 아닌데, 그 단어를 들으려고 너무 집중해서 질문 보기를 보고 있어서일까?
  • 캠브릿지10,17 을 통근시간마다 듣는데 아직까진 큰 효과는 없는 것 같지만, 공부했던 모든 사람(쌤, 후기 등) 무조건 많이 듣는게 좋다그래서 계속 진행중..

  • 라이팅 캠브릿지 기출문제 풀어보기
  • 스피킹 Part3 하루 한 개라도 해보기
  • 이제 이 사이클로 3번만 반복하면 끝날것 같아 괜찮았던 한주.

Nov, W3​

• Keep
  • 공부 사이클 유지
  • 아이엘츠 스피킹도 기출문제를 접해볼 정도의 수준이 되었다, 이유는 짧게 TMI는 길게 말해야한다는 게 이해가 되었고, 문법상 오류는 있지만 (전치사) 시제는 잘 버무려서 말이 나온다.
  • 파트3는 아이디어를 브레인스토밍하는데 상당한 시간이 걸리지만 주어를 그룹으로 묶고 갈라쳐서 이야기하면 되는데 한주 더 달리면 어느정도 감이 올 것 같다.
  • 운동 사이클 유지
  • 다친 뒤로 운동 사이클을 처음으로 다 완료한 주였는데, 넘 기뻤다. 이번주도 이대로만 가면 될 것 같다. 불가리안 스플릿 스쿼트는 할 때는 죽을맛인데, 하고나선 허리가 너무 편해진다. 오히려 런지보다도 부담도 덜가는 것 같고..
  • 풀업, 불스스는 무슨일이 있어도 하루에 한세트는 진행하는 운동으로 가져가야할듯..
• Problem
  • 리딩 파트1 13분 파트2 15분 파트3 19분 으로 끊어야 된다고하는데, 생각보다 더 타이트해서 이동시간에 보카앱을 보는 전략으로 바꿨다. 등교시엔 보카앱, 퇴근시엔 캠17 한 세트 (30분) 들으면 딱이다.
  • 스피킹은 사전을 찾아보는 습관이 있는데, 이렇게하면 절대 안 는다는 피드백을 받아서 충격이였다. 그냥 돌발로 녹음하고 절어도 1분 타이머 넣고 끊고, 그리고 다시듣고, 아이디어용 키워드 정리하고, 담준 이렇게 5일을 채워보기로.
  • 리스닝은 처음부터 집중을 해야하는데, 설마 지금 중요한 이야기하겠어? 라고 간과하다가 젤 쉬운 첫문제들을 틀린다. 문제좀 잘보자.
  • 라이팅은 쓸데없이 패러프레이징 하지말자. 패러프레이징은 감각이고, 아카데믹라이팅을 별도로 시간 내서 공부해야한다. 틀리면 6점이고, 복붙하면 7.5까지 나온다고한다.
  • 난 백일장이후론 에세이라는걸 한글로도 안 써본 사람이니 괜히 까불지말자. 입장, 근거, 예시, 설명, 정리 패턴으로 써보는 연습을 해야한다.
• Try
  • 실전스피킹 3개국어하는 분들도 생소한 주제가 나오면 전다는 걸 깨달았다. 그냥 기출문제보고 피하지말고, 제일 하기 싫은 스피킹부터 복습하고 나머지 숙제를하자.
  • 내 분야로 아는게 많으면 더 말하기가 어렵다고한다, 초등학생한테 말할 주제를 선정하자.

  • 아쉬움이 많은 한 주이지만 담주는 열심히, 약간 잘 되네? 했다가다고 다음날 아 왜이렇게 안되지? 의 반복이라 기분이 롤러코스터를 타는데 평정심을 찾자.
• Problem
  • 면접때문에 영어공부 사이클이 좀 깨졌다. 긴장이 풀렸기도하고 보상심리때문에 그날 하루는 놀아버렸다.
  • 파트3 질문에 이상한 게 나오면 아예 망해버린다. 결제한 시험일정을 취소했다.
  • 노트테이킹을 잘 보라는 피드백을 받으면 노트테이킹만 보다가 아이컨택트를 못하고, 아이컨택트를 해야한다는 피드백을 받으면 노트테이킹을 안본다.. 하..
  • 면접 - 난 대면면접은 하나도 안 떠는데, 대면으로 화이트보드에 그림그리는것을 포함해서 (사실 즐기는 편), 화상면접과 화상라이브코딩은 취약했다.
  • 이번은 라이브코딩을 한번 겪어봐서인지 그렇게 많이 떨지는 않았고 제대로 설명을 했다.
  • 인사팀이 경력/제출한 코드 위주로 설명을 할거라고 문서를 줘서, 신입검증용 질문을 하지 않을 줄 알고 집중을 약간 덜한게 아쉬웠다. 항상 Cs 지식을 보는데 면접 때 묻는 곳은 없는듯. 그건 기초체력으로 보고 신입면접용 질문들을 면접 한 시간 전쯤 보는걸로.
  • 엣지케이스를 물어본게 많아서 과연 다 잘 대답하는 사람이 있을까 싶다. 덕분에 이제 뇌리에 제대로 남았지만 :바닥을구르면서웃기:
  • 반에 피앙세가 있다는 예비 유부남이 시험일을 물어보며 게더링을 시도했지만 하필 그날이 면접날이라 너무 시니컬하게 대답한 것 같다. 담엔 국밥이라도 먹자고 해봐야지..
• Try
  • 정규반을 잘 소화하는 거에 박수를 치고 싶지만 수능에 빗대면 이제야 6월모의고사 끝낸 느낌이다.
  • yourielts 최신 기출과 캠브릿지 18을 1-2주간 잘 돌리고, computer based 시험도 한 사이클 돌리고 시험을 보는게 나을 것 같다. 올해 끝내자

DB 운영​

트랜잭션​

데이터의 정확한 일관성과 무결성을 보장하기 위해 완전히 종료해야하는 데이터베이스 처리의 논리적 작업 단위(Logical Unit of Work)

• 원자성: Atomicity, 분해가 불가능한 수행 단위로 완전히 수행 또는 수행되지 않음
• 일관성: Consistency, 트랜잭션이 성공적으로 완료되면 언제나 모순이 없는 상태 유지, 무결성 제약 조건
• 고립성: Isolation, 트랜잭션 실행 중 중간 연산 결과는 다른 트랜잭션 접근 불가
• 영속성: Durability, 성공적으로 완료된 트래잭션은 어떤 고장에도 손실 되어서는 안됨

트랜잭션 상태 전이​

• 실행 상태: Active
• 부분 완료: Partially Committed
• 완료 상태: Committed
• 실패 상태: Failed
• 철회 상태: Aborted

동시성 제어​

다중 사용자 환경을 지원하는 데이터베이스 시스템에서 여러 트랜잭션들이 성공적으로 동시에 실행될 수 있도록 지원하는 기능

• 트랜잭션 스케쥴: 각 트랜잭션을 구성하는 연산들이 시스템에서 시간에 따라 실행되는 순서
• 직렬가능성: Serializability, 트랜잭션들을 병행처리한 결과가 트랜잭션들을 순차적으로 처리한 결과와 같은 것
• 갱신분실 문제: Lost update problem
  • 트랜잭션이 동일 데이터를 동시에 갱신할 경우 발생하는 문제
  • 이전 트랜잭션이 데이터를 갱신한 후 트랜잭션이 종료하기 전에 이후 트랜잭션이 갱신 값을 덮어 쓰는 경우 오류 발생
• 불일치 문제: Inconsistency analysis problem
  • 다중 사용자 트랜잭션들이 동시에 실행될 때 DB가 일관성 없는 모순된 상태로 남는 문제
• 연쇄복귀 문제: Cascading rollback problem
  • 복수의 트랜잭션이 데이터 공유 시 특정 트랜잭션이 처리를 취소할 경우 다른 트랜잭션이 처리한 부분에 대해 취소 불가능

동시성 제어 기법​

• Locking
  • 트랜잭션이 사용하는 자원에 대해 상호배제(Mutual Exclusive) 기능을 제공하는 기법
  • 상호배제는 특정 트랜잭션이 데이터 항목에 대해 락을 설정하면 잠금을 설정한 트랜잭션이 언락될 때까지 데이터를 독점적으로 사용
• Time-stamp Ordering
  • 트랜잭션이 시스템에 입력될 때 타임스탬프 부여, 트랝개션의 수행 순서를 제어
  • 타임스탬프 값이 나중인 트랜잭션이 타임스탬프 값이 우선인 트랜잭션에 접근하고 있는 데이터 항목에 대한 접근을 요청하는 경우 롤백 당함
  • 직렬성 보장
  • 데드락 방지
• 낙관적 기법
  • 트랜잭션이 수행되는 동안 어떠한 검사도 실행하지 않음
  • 트랜잭션 수행 마지막에 갱신 사항들이 직렬가능성을 위반하는 경우가 있는지만 검사하여 이상이 없을 경우 트랜잭션을 확정
• 낙관적 기법 단계
  • Read Phase: DB를 읽고 개인적인 복사로 갱신, 트랜잭션 갱신은 모두 임시 갱신파일에 기록, 다른 트랜잭션에 의해 접근 불가능
  • Validation Phase: 가해진 변화가 데이터베이스의 무결성과 일관성에 영향을 주지 않을 것이라는 것을 보장하기 위해 검증됨, 이상 있을 경우 트랜잭션 재시작 및 롤백.
  • Write Phase: 변경사항이 영구적으로 DB에 적용됨

Locking 기법​

• Shared Lock: 공유 잠금한 트랜잭션은 데이터 항목에 대해 읽기만 가능, 다른 트랜잭션도 읽기 만 실행 가능
• Exclusive Lock: 전용 잠금한 트랜잭션은 데이터 항목에 대해 읽기와 쓰기 모두 가능, 다른 트랜잭션은 읽기/쓰기 불가.
• DB -> Table -> Row -> Column: Locking overhead 증가, 자료 공유성 높음.

2 Phase Locking​

모든 트랜잭션이 lock과 unlock 연산을 확장단계와 수축단계로 구분하여 수행

• 확장단계: 트랜잭션은 lock만 수행할 수 있고, unlock은 수행할 수 없는 단계
• 수축단계: 트랜잭션은 unlock만 수행할 수 있고, lock은 수행할 수 없는 단계
• 직렬간으성을 보장할 수 있는 규약으로 가장 많이 사용됨.
• 교착상태 발생될 수 있으나 예방과 탐지로 해결.

2 Phase Commit​

분산 데이터베이스 환경에서 원자성을 보장하기 위해 분산 트랜잭션에 포함하는 메커니즘 Prepare와 Commit 단계를 통해 모든 노드가 커밋하지 않으면 롤백하는 기법

• Phase 1: 준비 단계
  • 한 지역노드에서 커밋 요구, Global Coordinator가 Commit Point Site 결정
  • Prepare Message 를 전송하고 원격 노드는 Prepare Message Reply
• Phase 2: 커밋 단계
  • 모든 지역 노드가 커밋 준비되었다는 것을 받은 경우 각 노드에 Commit을 명령함
  • Global Coordinator가다른 지역 노드로부터 에러 보고를 받을 시 롤백 명령

DB 회복​

장애 발생시 데이터베이스를 장애 발생 이전 데이터베이스의 내용에 모순이 없는 일관된 상태로 복원시키는 것을

장애 유형​

• 트랜잭션: Transation Failure, 잘못된 입력, 데이터를 찾을 수 없는경우, 오버플로우, 가용자원 초과 요청 등으로 트랜잭션 동작 불가
• 시스템: System Failure, 교착상태로 트랜잭션이 작업 불가, 하드웨어 오작동으로 휘발성 기어장치의 데이터 손실
• 미디어: Media Failure, 비휘발성 기억장치(하드디슼) 고장으로 디스크 블록이 붕괴

회복 요건​

• 덤프: 데이터베이스 내용을 일정기간마다 다른 저장소에 저장, 백업정책에 의거하여 다른 디스크 또는 특정 가용 공간에 복사
• 로그: 데이터베이스 내용이 변경될 때마다 변경 내용을 로그파일에 실시간 저장

회복 기법​

• 지연갱신
  • 트랜잭션이 부분완료 상태에 이르기 전까지 발생한 모든 변경내용을 로그파일에 기록하고, DB에 저장하는 것을 지연시키는 방법
  • 트랜잭션 실패시 로그파일의 내용만을 폐기하면 되므로 Undo필요없음
• 즉시갱신
  • 변경내용을 DB와 로그파일에 동시에 저장
  • 트랜잭션 수행 도중 실패한 경우 로그파일의 내용을 참조하여 변경 이전 값으로 수정하는 Undo과정 필요
• 검사점: Check Point
  • 변경내용을 로그파일에 기록하고, 일정시간마다 체크포인트를 발생시켜 그때까지의 변경사항을 디스크에 저장, 로그파일에는 체크포인트를 기록
  • 장애시 체크포인트 이전 처리된 트랜잭션은 회복작업에서 제외하고, 이후 처리된 트랜잭션에 대해서만 Redo 또는 Undo 수행.
  • Check point interval 관리 필요
• 그림자페이지: Shadow Page Table
  • 트랜잭션 실행 중 현재 페이지 테이블과 그림자 페이지 테이블을 이용
  • 현재 페이지 테이블은 메인메모리, 그림자 페이지 테이블은 하드디스크에 저장
  • 트랜잭션 변경 연산이 수행되면 현재 페이지의 테이블 내용만 변경하고 그림자 페이지 테이블의 내용은 변경하지 않음
  • 트랜잭션이 성공적으로 완료될 경우, 현재 페이지 테이블의 내용을 그림자 페이지 테이블의 내용으로 저장
  • 데이터 단편화 및 그림자 페이지 테이블 복사, 쓰기에 오버헤드 발생

    • 모든 응용 프로그램 컨테이너에 사이드카 컨테이너를 추가하여 배포, 서비스의 모든 네트워크 트래픽을 처리.
    • 서비스가 타 서비스를 직접 호출하는 것이 아닌 프록시를 통해 호출하므로 로깅, 모니터링, 보안, 트래픽 제어 가능.

Agile 방법론​

• ASD: Agile Software Development.

XP​

• eXtreme Programming

TDD​

• Test Driven Development
• Need --> Test --> Refactoring --> Code
• Process
  • 단위테스트 형식으로 스펙 작성
  • 실패하는 테스트를 작성하고 확인
  • 스펙을 만족하는 코드를 작성
  • 테스트 확인
  • 코드와 테스트코드 리팩토링
  • 반복

Scrum​

• Role
  • Product Owner
  • Scrum Master
  • Scrum Team
• Process
  • Product Backlog
  • Sprint Backlog
  • Burndown chart
    • 개발 완료까지 남은 작업량을 보여주는 그래프
    • 각 이터레이션 별로 남아있는 작업량을 스토리 포인트라는 것으로 나타낸 것
• Meeting
  • Sprint Planning
  • Daily Scrum
  • Sprint Review
• 특징
  • Transparency
  • Time boxing: 일일 스크럼은 매일같이 15분이라는 짧은 시간에 진행해야함, 스프린트 리뷰는 매 이터레이션마다 주기적으로 진행.
  • Communication: 플래닝포커, 각 사용자 스토리의 구현 난이도/시간을 토론, 협의하는 절차
  • Inspect & Adapt model: 경험주의 모델, 개개인의 경험에 기반하므로 프로젝트마다 고유한 상황과 특징을 갖고 있음, 팀마다 달라지는 걸 허용함.

LEAN​

• 도요타에서 시작, 파레토 법칙으로 정말 중요한 20%에 집중
• 원칙
  • 낭비 제거하라
  • 품질 내재화하라
  • 지식 창출하라
  • 확정을 늦춰라
  • 전체를 최적화하라
  • 사람을 존중하라
  • 빨리 인도하라

DevOps​

개발자와 비 개발자 사이의 대화와 협동, 통합을 강조하고 담당업무와 직급의 장벽을 허물고 상호 이해를 추구 소프트웨어 개발과 IT운영 간의 상호의존 관계를 개선하기 위해 등장, 소프트웨어 제품 및 서비스를 빠르게 생산하려는 조직을 돕는 것이 목적.
