Six Articles, One Insight
I published six articles this week:
- PostgreSQL
- AI agents
- Context management
- Automation tutorial
- Debugging analysis
- Adversarial advice framework for evaluating MVPs
It wasn’t planned—each piece came from a paper, a talk, or a project that caught my eye.
But looking at them together, a common thread emerges:
All six are saying the same thing.
The Six Examples
| Domain | “Boring” solution that works | “New” promise of something better |
|---|---|---|
| Databases | PostgreSQL + PgBouncer | Distributed database with sharding |
| AI agents | while loop + tools | Multi‑agent architecture with orchestrator |
| Context management | YAML + README + circular buffer | RAG with vector store + embedding pipeline |
| Automation | cron + bash + curl | Cloud‑native orchestration platform |
| Debugging | Observe → reduce → hypothesize → verify | End‑to‑end interpretability tools |
| Idea evaluation | Structured debate with published frameworks | Market‑research platform with panel data |
The left column shows what teams solving problems at scale actually use.
The right column shows what’s being sold at conferences.
Why the “Boring” Solutions Win
- PostgreSQL – Bohan Zhang’s article on OpenAI’s scaling showed 800 M users on a single primary, no sharding, just PgBouncer (2007) and read replicas (90s tech).
- AI agents – Michael Bolin dissected coding agents: a simple
while Trueloop with an LLM, tools, and a stop condition. No knowledge graphs, no symbolic planners. - Context engineering – OpenAI’s Cookbook notes that injecting a README, trimming history, or summarising old data are all classic techniques.
- Automation – The tutorial demonstrated that OpenAI’s Codex Automations are essentially
cron + curl + LLM. The scheduler is 40 years old; the brain is 2 years old. - Debugging – The Jane Street puzzle (2,500‑layer net = MD5) was solved with classic debugging: observe data patterns, simplify, narrow options. Modern tools helped, but the method was timeless.
- Idea evaluation – Simulating five experts with an LLM is just a cheap wargame—pre‑mortems have existed since the 1950s; the only change is the cost (≈ $2 in tokens vs. $50 k consulting).
These observations echo long‑standing wisdom:
- Dan McKinley – “Choose Boring Technology” (2015)
- DHH – “Don’t Kubernetes a CRUD app”
- Fred Brooks – “No silver bullet” (1975)
The Core Message
New technology solves problems most teams don’t even have.
| Example | Why the “new” tech isn’t needed |
|---|---|
| OpenAI DB | 95 % reads → a single primary handles writes after off‑loading heavy writes elsewhere. |
| Coding agents | The model can decide, in a simple loop, which tool to use and when to stop. |
| Cron‑based automation | 99 % of automations are “run every N hours.” Only edge cases need sophisticated orchestration. |
Complexity Bias
We tend to favor complex solutions because they feel appropriate for hard problems. A “hack” (e.g., moving heavy writes) may feel like a shortcut, while sharding with consistent hashing feels like “real engineering.” Yet the hack often works faster and cheaper.
Opportunity cost: The time spent building an elegant, unnecessary solution is time not spent delivering value.
Practical Takeaways
Ask yourself:
What problem am I solving that boring technology can’t handle?- If the answer is “none, but the new one sounds cooler,” you’re adding needless complexity.
- If the answer is “I need X, and PostgreSQL doesn’t have it,” adopt the new thing—be specific about X.
Leverage existing tools with discipline:
- OpenAI solved its connection bottleneck with PgBouncer—no new database, no data‑layer rewrite.
- Identify the real problem, not the one you think you have.
Remember the cost of complexity:
- More bugs, longer onboarding, 3 a.m. fire‑drills.
Closing Thought (unfinished)
Am I solving a real problem or a future problem…
(The sentence was cut off in the original draft.)
> “It won’t scale” is the most expensive phrase in software engineering.
> Because it’s usually correct — technically, nothing scales infinitely.
> But in practice, 99 % of projects die before scaling becomes an issue.
> And the 1 % that survives will have the resources to fix it when the time comes.
It’s not that using a distributed database written in Rust with its own consensus protocol isn’t cool.
It’s awesome. It makes for great talks. It looks fantastic on a résumé.
But if what you need is **PostgreSQL** with a connection pooler and properly written queries, the distributed database is a cost with no benefit.
And the cost isn’t just technical — it’s cognitive. Every hour spent configuring the cluster is an hour not spent:
- understanding your data,
- optimizing your queries,
- talking to your users.
Boring discipline — simple queries, aggressive timeouts, workload isolation, cron jobs running scripts, up‑to‑date READMEs, methodical debugging — doesn’t make the keynotes.
It doesn’t have a logo. It doesn’t get its own conference.
**But it works when nothing else does.**
And this week, six unrelated articles reminded me of that all at once. Sometimes, the common thread reveals itself. You just have to look for it.The six articles from this week
- OpenAI scales PostgreSQL for 800M users with a single writer – The battle‑hardened database that delivers what the new kids promise.
- Your AI coding agent is just a while loop with delusions of grandeur – Dismantling the magic of Codex CLI and Claude Code.
- Context engineering: the invisible skill – What the model sees matters more than the model itself.
- Codex Automations, no Codex needed – cron + bash + LLM = midnight agents.
- A 2,500‑layer neural net turns out to be MD5 – Classic debugging meets ML.
- Five non‑existent experts review your startup – Adversarial debates as a decision‑making tool.
