Let’s not kid ourselves, Postmark is a great email service inalmostevery regard. However, if you’re reading this, the chances are that it doesn’t fit your needs anymore, and you’d like to switch it up a little bit. Luckily, you’ve come to the right place! I’ve interviewed our very own deliverability..

Sharding breaks a heavyweight database into bite-sized chunks spread across servers. That means better scalability, less strain on any one node. The key? Picking the right shard key. Get that wrong, and you’re in cross-shard query hell. Modulo, range, and consistent hashing each slice the pie diff..

Claude Code zips out Ruby functions, tests, and pull requests viaCLIprompts across multiplegit worktrees. It slays manual typing and ejects IDE plugins. It spins up ephemeraltest environmentsto replay bugs, pries open externalgemcode, and syncs branches, commits, and PRs in one go...

OpenAI’s rewritingCodexinRust, ditching the oldTypeScriptversion. Why? To ship it as a single static binary—no messy installs, no glue code juggling. Just run. Rust cuts down runtime failures, trims the attack surface, and kills off toolchain sprawl. Less fragility. More control. System shift:Team..

Turso just dropped the alpha of itsRust-based SQLite rethink—rewritten from scratch to handle today’s mess:async APIs,built-in vector search, and actualconcurrent writes. Forget the old SQLite playbook. Turso’s version leans into modularity, bakes in deterministic tests, and still aims for SQLite-l..

RudderStack crankedPostgreSQLup to100K events/secas a queuing engine. The secret sauce: tight tuning of job partitioning, smarter indexing, tuned VACUUM timing, and compaction that didn't choke. Recursive CTEs stood in for loose index scans. Caching cut I/O repeats. They ditched byte slices to side..

A sharp teardown ofWindows vs. Unix file deletion semanticslands on this: Windows leans on read-write locks; Unix rolls with a looser, non-blocking vibe—more likeweakly-isolated DB transactions. It trades consistency for concurrency, dodging locks even if it means the rules get fuzzy. The post zoom..

This guide breaks down the major Git branching strategies—GitFlow,GitHub Flow,GitLab Flow,Trunk-Based Development, and a few others that still show up in wild repos. Each one gets sized up by structure, use case, and trade-offs. Think: how big the team is, how fast releases go out, and how people l..

OCaml’s grown up. Multicore support is in. So are user-defined effects. Under the hood, affine types, staged metaprogramming, and effect typing are steering it toward resource-safe programming—with actual thrust. Its type system still slaps: powerful modules, GADTs, algebraic types, and now first-c..

AI agents can help wrangletest suite maintenance—if you treat them likejunior devs. That means tight prompts, clear boundaries, and someone keeping an eye on them. Teams get better results when they feed agents sharp context and task them with small, scoped jobs instead of vague laundry lists...
