MUST and MUST NOT; On Writing Documentation Revise documentation, many times, and on separate days to catch confusing parts. Beware of ambiguities, e.g. X may not do Y. Refer to definitions, e.g. RFC 2119 . Put yourself into different roles, e.g. the person just looking for samples, the person who wants to read up on every nook and crany, the person who has no technical background etc....

Pagination with Relative Cursors Exposing pagination through URLs like example.com/items?page=25&limit=100 leads to SQL like SELECT * from 'items' LIMIT 100 OFFSET 2400;, which inefficiently goes through 2,500 records and discards the first 2,400. With relative cursors, we have URLs like example.com/items?limit=50&lastID=XXX, which leads to SQL like SELECT * from 'items' WHERE 'id' > XXX ORDER BY 'id' ASC LIMIT 50, and this is more efficient, assuming there are indexes for id....

Mergeable Replicated Data Types On a distributed system, each replica should [eventually] converge to the same state. Commutative Replicated Data Types (CRDTs) can accept updates and achieve consistent without remote synchronization. The Need for Commutativity Say we have a queue \( 1 \to 2 \). Suppose two replicas, \(r_1\) and \(r_2\), independently call pop(). Each replica will have \(2\) on their queue. However, on receiving an update that the other replica popped, each replica will call pop() to be consistent, thereby deleting \(2\)....

Dependency Management Golang introduced a new library referencing mode to overcome limitations of the old one. While the two library modes are supported by Golang, they are incompatible, e.g. dependency management (DM) issues, reference inconsistencies, build failures, etc. did an empirical study that resulted in HERO, an automated technique to detect DM issues and suggest fixes. Applied to 19k Golang projects, HERO detected 98.5% on a DM issue benchmark, and found 2,422 new DM issues in 2,356 Golang projects....
