First Come First Served: The Impact of File Position on Code Review

The most popular code review tools (e.g., Gerrit and GitHub) present the files to review sorted in alphabetical order. Could this choice or, more generally, the relative position in which a file is presented bias the outcome of code reviews? We investigate this hypothesis by triangulating complementary evidence in a two-step study. First, we observe developers' code review activity. We analyze the review comments pertaining to 219,476 Pull Requests (PRs) from 138 popular Java projects on GitHub. We found files shown earlier in a PR to receive more comments than files shown later, also when controlling for possible confounding factors: e.g., the presence of discussion threads or the lines added in a file. Second, we measure the impact of file position on defect finding in code review. Recruiting 106 participants, we conduct an online controlled experiment in which we measure participants' performance in detecting two unrelated defects seeded into two different files. Participants are assigned to one of two treatments in which the position of the defective files is switched. For one type of defect, participants are not affected by its file's position; for the other, they have 64% lower odds to identify it when its file is last as opposed to first. Overall, our findings provide evidence that the relative position in which files are presented has an impact on code reviews' outcome; we discuss these results and implications for tool design and code review.

Fuck CBS, Paramount, Ellison. This is no "financial decision." It is Trump taking over American media. This is Hungary. This is disgusting.

富士通とかNECの自治体システム、選択的夫婦別姓のための戸籍データ改修なんて10年前ぐらいに終わってても不思議じゃないよな――というか、もしやってなかったら開発部を刷新する程度の失態。
下手するとシステム間通信のテストぐらいしててもおかしくない。

판타지

"저기, 저 온몸에 쫄쫄이 잠수복 입은 애들 뭐야? 특수부대인가? 아니 이번 작전 내륙작전 아니야?"

"아, 신무기 파일럿."

"신무기 파일럿?"

"저기 커다란 갑주 보이지? 저기 탈거야."

"어? 그거 트롤 돌격병 아니었어?"

"우리한테 트롤 돌격병이 어디있어? 그런 고급 인력이?"

"그럼? 저 갑주가 신무기란 말이야? 드워프 기계 장치인가?"

"그런거면 얼마나 좋겠냐만, 드워프 기계장치가 좀 비싸? 거기다가 교육 받으려면 얼마나 시간이 걸리는데? 그 교육도 다 돈인데 위에서 해주겠냐?"

"그럼?"

"만병통치약, 키메라."

"키메라? 키메라 웨펀이라고? 그건 말이 안되지 않나? 저게 자립형 전투 키메라가 아니라 파일럿이 들어가는 무기라면, 정신 동기화를 이용한 생체 갑주일텐데? 그건 비용이 어마무시하잖아? 게다가 그거 파일럿 동기화 때 정신 오염도 일어나고!"

"너 갑자기 말이 빨라진다?"

모든 새드엔딩을 싫어하지만 '등장인물들은 행복한 척 하지만 누가 봐도 사실상 새드엔딩인 해피엔딩' 따윈 절대 용서할 수 없어 시청자 가슴 박박 찢어놓고 니들만 행복한 척하지 말라고 젠장~~~
