🛠️ Go ahead, self-host Postgres
A solid pushback against the “managed everything” mindset, reminding teams that hands-on infrastructure knowledge can still be a real advantage.
This essay argues for running PostgreSQL yourself rather than defaulting to managed cloud services like AWS RDS. Based on real-world production experience, it shows that self-hosting can be cheaper, more transparent, and nearly as reliable with modest operational effort. The article walks through concrete configuration tips, trade-offs, and cases where managed databases still make sense.

🧭 The mysterious forces steering views on Hacker News
Regardless of where you land, it’s a sharp reminder that platform design quietly decides which ideas get amplified.
The author contends that Hacker News actively shapes content visibility through moderation and ranking, rather than acting as a neutral aggregator. By analyzing traffic logs and specific incidents, they describe abrupt drops in exposure for posts critical of Y Combinator–linked projects. The article frames this as a form of soft censorship that influences discourse in the tech world.

⚙️ Hash tables in Go and the limits of old optimization tricks
A strong case for rechecking assumptions as runtimes evolve—and for not blindly trusting cargo-cult optimizations.
The article explains how Go’s move to Swiss Tables in Go 1.24 changed map internals, breaking the long-standing memory optimization of using map[int]struct{}. By reading the compiler and runtime source, the author shows how alignment and padding eliminate the expected savings. It contrasts old and new map layouts and debunks advice that’s still commonly repeated.

🌐 I spent a week without IPv4 to understand IPv6 transitions
A refreshingly practical account that replaces theory with lived experience of IPv6 in the wild.
The author documents a week-long experiment running exclusively on IPv6 to explore real-world transition mechanisms away from IPv4. The article explains dual-stack, NAT64, DNS64, and 464XLAT, highlighting what works and where friction still exists. It concludes that IPv6 is technically ready, but human and operational inertia remains the main barrier.
