Performance

Java’s ‘Everything Is an Object’ Promise Just Died. Here’s What That Means.

JEP 401 merged into OpenJDK master, bringing value objects that eliminate identity overhead. The performance gains are real, but the hidden disruption is that code relying on object identity β€” == comparisons, synchronization, weak references β€” will silently break. Java’s ‘everything is an object’ era is ending.

I Rewrote Postgres in Rust. Now It’s Faster Than Postgres and ClickHouse.

A Rust rewrite of Postgres that ditches the legacy process-per-connection model, adopts threads and direct-to-binary codegen, and integrates Arrow/SIMD. The result: a single database that outperforms both Postgres and ClickHouse. The language is just the enablerβ€”the real breakthrough is architectural.

I Forked MinIO and Deleted Code. Here’s Why Less Is Actually Faster.

Forking MinIO and stripping away its accumulated abstractions proves that raw performance gains come from deleting code, not adding it. While this lean alternative offers blistering speeds that break through latency ceilings, it forces a trade-off between raw speed and the ecosystem trust of the original open-source project. Sometimes, the most radical optimization is just a scalpel.

Your AI Isn’t Getting Dumber. It’s Getting Rationed.

Your AI assistant isn’t getting stupiderβ€”it’s being throttled by compute economics. A developer’s observation on Hacker News reveals a hidden latency tax: as demand surges, your response time becomes a proxy for infrastructure strain. The real bottleneck isn’t algorithms; it’s server capacity. Over-reliance on any single provider is an operational risk.

Microsoft Left Your Clipboard Broken. Developers Are Making It Worse.

Windows 11’s clipboard is broken. Indie developers are trying to fix it, but they’re building clipboard managers with Electron and React β€” the same heavy web stack that powers Slack. The result: a ‘lightweight’ tool that eats 200MB of RAM. This is a story about developer convenience, user neglect, and the quiet tragedy of the most essential feature you never think about.

WordPress Search Isn’t Slow. Your Database Is Just Lazy.

WordPress search isn’t inherently slow β€” it just ships without an inverted index, the same data structure every real search engine has used for decades. By building a custom index table alongside WordPress’s standard schema, search on 50,000 posts drops from 2+ seconds to under 50 milliseconds. No Elasticsearch. No SaaS. Just the right data structure, finally implemented.
