Multi-factor authentication is becoming increasingly prevalent. Many companies’ information security policies require employees to use MFA when available—and it’s just good practice.

I’ve recently been looking into various row-level security schemas for Postgres, and came across this excellent article benchmarking a few different architectures for row-level security. That post shows benchmarks for Postgres 10—three major versions ago.

I forked the repo (GitHub), upgraded to Postgres 13, and added a new architecture based on Carl Sverre’s comment to see what’s changed.

I ran each benchmark on a maxed 2019 16” MacBook Pro (2.4 8-core/64GB RAM), with 100 users and 10,000 total items. Notably, all of my results are significantly slower than what the original post achieved—I suspect this comes from running Postgres in Docker on MacOS, which has known disk performance issues.

RLS + ACL column

In this schema, ACLs are stored directly in columns on the secured table. Public items are handled as just another role.

I think one of the most predictive features for personal happiness is whether you have high-quality hobbies. My friends and acquaintances with hobbies seem consistently happier and more fulfilled than those without, independent of other factors like job satisfaction, financial success, and physical health.

My time in Montana is coming to an end—I’ll be spending the next few days camping in Glacier National Park, then heading back down to Atlanta. This past summer really was something special—Livingston and the whole state just have great vibes.

Goal Tracking

• 🟢 Get 1% faster. Not much to say here—I hit this goal and it’s the offseason! Since preseason is coming up again, I’ll probably change this goal next month.
• 🔴 50% less discretionary spending. I spent just 1.8% less this month than my 2020 average. In retrospect, expecting to hit this goal while in Montana was probably foolish—I’ve been way more lax about eating out and paying for experiences than normal.
• 🔴 One hour of solitary free time a day. Still not tracking this—clearly I’m not prioritizing this goal. A good lesson for next time.
• 🟡 Twice-weekly live conversations with friends. Managed this all but one week this month.

The central concept in James C. Scott’s Seeing Like a State is legibility, and how states’ desire to make their societies more legible often leads to disaster. Others have detailed the main points of Seeing Like a State far better than I could—please start with those three if you’re not familiar (or just read the book, which is excellent!)
