Stack ExchangeAcademicEngagementKnowledge sharingQ&ASocial graphSoftware development The content of reverseengineering.stackexchange.com (https://reverseengineering.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 50,094 rows: 21,188 posts (9,681 questions, 11,045 answers, 230 tag wiki excerpts, 230 tag wikis and 2 posts of type 7) and 28,906 comments, written between 19 March 2013 and 31 March 2024. Beside it are 36,519 user accounts, 80,473 votes, 48,084 badges awarded, 343 tags, 67,683 post revisions and 1,342 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 140 rows.
