| | | PostgreSQL arrays look simple until they quietly wreck performance or correctness. This deep dive explains when arrays help, when they hurt, and how indexing, query planning, and storage details shape real-world behavior.

| | Great post if you’re using Claude Code and feel like you’re only scratching the surface. There are thirty-one practical tips here, covering memory, context, shortcuts, planning modes, agents, and automation from someone who’s clearly using this every day.

| | | | Default charts fail more often than we admit. This post shows why accessible line charts aren’t about rules or palettes, but about clarity, intent, and sometimes changing the chart entirely. It's a great reminder that good viz is about people first.

| | Here’s a nice peek into what strong teaching + doing looks like in data viz. In their final course projects, Carnegie Mellon University students tackle real questions like redistricting, drug prices, commuting, and even keyboard shortcuts, with thoughtful framing, clear audiences, and polished visual storytelling. Worth browsing for ideas and inspiration.

| | | If Claude Code keeps struggling with R, this is a useful lever. It's a project-level CLAUDE.md file that encodes modern tidyverse and rlang conventions, and you get cleaner, more idiomatic R output without re-teaching the agent every session.

| | | Spatial data science looks similar across languages, until it doesn’t. This paper digs into what R, Python, and Julia have in common, where they diverge, and what still needs work, covering geometry semantics, variable support, spherical geometry, formats, and interoperability.

| | | We tend to think of data centers as anonymous boxes. This Bluesky thread highlights projects that challenge that assumption, with data centers designed as civic spaces, landmarks, and architectural statements. Unexpected and compelling.
