The Best Code Review Says Less
You open a pull request and there are 40 inline comments waiting for you, all from the AI reviewer. It has opinions about a variable name. It wants you to extract three lines into a helper. It found a null that can’t actually occur, on a path that never runs. It’s suggesting a micro-optimization on code that executes twice a day.

Lombok is Still Relevant in the Age of Java Records
Swaranga Sarma, a Java developer who has used Project Lombok for about 15 years, rebuts common arguments against it (weird bugs, compiler hacks, Records making it obsolete, future JDK breakage) and explains why its benefits still outweigh the costs, with delombok as an easy exit.

How to write an effective software design document
Michael Lynch draws on experience writing design documents at Google, Microsoft, and his own companies to explain when to write one, how much to invest in it, and what to include. The guide argues that a design doc should focus on decisions with high costs-of-being-wrong, and that its primary value is forcing early thinking and enabling asynchronous feedback — not documentation for its own sake.

Reviewing code in the agent era
Reviewing code in the agent era Last week we launched Diffs, a new way to review PRs directly inside Linear. Since then we’ve had a lot of questions about it, so we wanted to share more about why we built the feature and how we use it ourselves today. Like a lot of people who build software, I f...

How Readyset Rewrites Your SQL: Inside the Query Transformation Pipeline
Vassili Zarouba explains why Readyset's incrementally maintained dataflow cache needs SQL rewritten into canonical forms, and walks through its pipeline of composable, semantics-preserving passes, including array constructor rewrites, redundant join elimination, left-spine hoisting, subquery decorrelation and three-valued logic for IN and NOT IN.

Java sealed classes and exhaustive pattern matching
Neil Madden explains that exhaustive switch pattern matching over Java sealed types makes adding a new subtype a breaking change, and that consumers which aren't recompiled only fail at runtime. He argues sealed types used across module or API boundaries can introduce new ways to break code, citing the PEM-encoding JEP preview.

Software is still about thinking
Cursor’s head of design argues AI coding creates an illusion of speed without structure: unclear systems thinking now produces slop at scale, while clear architecture compounds into 100x leverage.

What makes Lisp difficult to read?
The Lisp family of programming languages is infamous for their parenthesis-heavy syntax. Many people, myself included, find this syntax more difficult to read than the notation of languages like Python, Java or C. The perceived unreadability of Lisp is so significant that multiple attempts have been made to create new notations to aid Lisp’s adoption. Yet, despite these attempts and Lisp being nea

A short opinion piece arguing constructors should never throw, do async work, or perform side effects; parsing, connecting, and validation belong in factory methods or explicit lifecycle methods so object construction stays simple and predictable.

All you need is Wide Events, not “Metrics, Logs and Traces”
Ivan Burmistrov argues that the three pillars of observability, metrics, logs and traces, cause needless confusion, and that a single system built on wide events, as he used at Meta with Scuba, can answer debugging questions, derive traces and metrics, and support cross-correlation and root cause analysis.
