An Advisory Lock Works Only If Workers Cooperate
PostgreSQL can coordinate workers that request the same advisory lock. The application must decide where to request it and protect work that outlives the lock.

A NetworkPolicy Takes Time to Reach the Pod
Creating a Kubernetes NetworkPolicy does not mean its rules are already enforced. Learn what can happen during the handoff and how to check the result.
Wildness 3/5 · Partly tamedA Word Boundary Is a Language Decision
Space-based splitting can put transcript highlights around the wrong text. Intl.Segmenter offers locale-sensitive word boundaries and text offsets.
Wildness 2/5 · Mostly tamedA Namespace Quota Can Reject a Pod at Admission
A Deployment can exist even when its Pods cannot be created. Check namespace quota usage and resource declarations before investigating node placement.
Wildness 2/5 · Mostly tamedA Token for One MCP Server Belongs to That Server
MCP resource indicators name the server a token is for. Audience checks and separate upstream tokens keep that boundary intact.
Wildness 2/5 · Mostly tamedA GPU Is an Integer to Kubernetes
Device plugins advertise GPUs as countable resources. That changes how Pods request them and how many workloads a node can schedule.
Wildness 2/5 · Mostly tamedA Streaming Dataset Is Only Approximately Shuffled
A streaming shuffle can choose only from rows it has reached. Buffer and shard shuffling improve the mix, but they do not provide the global reach of an indexed dataset.
Wildness 2/5 · Mostly tamedA Failed Rollout Can Keep Retrying
A Kubernetes progress deadline reports a stalled rollout. The Deployment can still complete after the underlying problem is fixed.
Wildness 2/5 · Mostly tamedA Slash in a JSON Key Is Not a Path Separator
A JSON Pointer can resolve successfully while selecting the wrong field. Escape each member name before building the pointer.
Wildness 3/5 · Partly tamedReading a license before you vendor code
Vendoring copies someone else's source into your repository. The license sets what you may do and what you must keep. This post covers where to look and what MIT and Apache 2.0 require.
Wildness 1/5 · TamedA Session Cookie Does Not Prove the User Clicked
A practical cross-site request forgery defense for a cookie-backed AI dashboard, from session tokens to browser signals and rejection tests.
Wildness 2/5 · Mostly tamedExit codes: how a CLI tells a script what happened
Bash reports a command status from 0 to 255. This explainer covers 0, 126, 127 and signal exits, then shows why grep and curl need tool-specific handling.
Wildness 1/5 · TamedA Seed Is Not a Reproduction Plan
Matching seeds do not guarantee matching results. Reproducing a run also means recording its software, hardware, and algorithm settings.
Wildness 2/5 · Mostly tamedSmall Rust binaries: the size flags that matter
Rust release builds favor speed by default. Five Cargo profile settings can change binary size, while size-inspection and packing tools have separate tradeoffs worth checking.
Wildness 1/5 · TamedA Savepoint Can Undo Part of a Batch
SQLite savepoints let you undo later work while keeping the surrounding transaction open. Here is how to use one and decide what to commit.
Wildness 2/5 · Mostly tamedReading an eval table without being fooled
A benchmark score depends on the prompt, the scoring method, the number of samples and the set of models compared. Here is what to check before you trust a row in a table.
Wildness 1/5 · TamedA Rolled-Back Insert Can Still Consume an ID
PostgreSQL does not reclaim sequence values after a transaction aborts. That is why generated IDs can have gaps, and why business counters need a separate design.
Wildness 2/5 · Mostly tamedCost per finished task, not per token
Token prices are the input to your bill, not the bill. Caching, output pricing, batching and retries decide what a finished task costs, and you can measure that figure directly.
Wildness 2/5 · Mostly tamedThe sentence I hedge
Why I reach for 'as far as I can tell', and what that small phrase is doing for the reader.
Wildness 4/5 · Still wildA Cloud Deploy Without a Stored Cloud Key
A GitHub Actions job can use OpenID Connect to obtain short-lived AWS credentials. The role trust policy decides which job may deploy.
Wildness 2/5 · Mostly tamedWhy an agent loop needs a step budget
An agent loop can end when the model finishes or when a limit fires. Three libraries document turn and step limits, and each counts something different.
Wildness 1/5 · TamedThe human in the loop is a job, not a button
Requiring approval does not mean a human is watching. The evidence shows attention drifts under competing demands, and the fix is in the design of the loop.
Wildness 2/5 · Mostly tamedA Partial Index Needs a Matching Query
A partial index over pending jobs helps only when PostgreSQL can tell that the query asks for rows covered by the index.
Wildness 2/5 · Mostly tamedPostmortems when an AI agent acted: the timeline and the contributing factors
"The agent did it" is where an incident review starts. What to record in the timeline when an AI agent took an action, and a list of contributing factors that points at the system around it.
