Databricks buys Electric to embed local Postgres in AI agents

Databricks is acquiring the startup Electric to integrate WebAssembly-based Postgres databases directly into application environments for an undisclosed amount. This strategic move provides developers with a specialized method to keep data geographically and logically closer to AI agents as they construct increasingly autonomous enterprise software systems. Accelerating Agent Workflows w...

European SaaS Expired Session Cleanup: Idempotent Python Drains Rate-Limited Workers

For a European SaaS, cheap expired sessions cleanup sounds like a cron calling a public URL; the real constraint is proving that retries cannot delete the wrong session or flood a constrained worker pool. Short answer: expose an authenticated public HTTP trigger, let cron call it, and make that trigger enqueue deterministic, retry-safe cleanup batches rather than deleting expired sessions inside ...

I Built a Puerto Rican Mountain Kitchen. The Only Image Is the Favicon.

This is a submission for Frontend Challenge - Comfort Food Edition, Perfect Landing. What I Built The only image file in this project is the favicon. No <img> tag anywhere. No inline SVG. No url() in any stylesheet. The pot, the broth, the steam, the fire, the rain running down the glass, the fog on the mountains, the moon, the roots floating in the bowl — every one of them is H...

Spaghettifying DRAM: How AI Workloads Are Reshaping Memory Architecture Challenges in 2026

In 2026, AI training workloads will dominate global DRAM demand, overshadowing traditional computing needs. Generative AI models like GPT-5 will rely heavily on memory technologies such as High-Bandwidth Memory (HBM), making HBM the backbone of AI systems. Meanwhile, consumer electronics will struggle with diminished memory supply and soaring costs. The entire memory market is undergoing a signif...

Gate the Patch, Not the Model: A Three-Check Loop for Untrusted Code Outputs

A generated patch can look correct and still fail in three ways that a prompt screenshot cannot show: it changes the contract, it imports a module the rest of the codebase does not allow, or it only works on the single example in the prompt. If you copy that patch into a real repository, you become the integration test, usually in a pull request late at night. This article walks through a short v...

A Flake Triage Card for Your CI: Classify Failures First, Read Logs Second

CI goes red for reasons that have nothing to do with your change. A port collision on a shared runner, a test that expects a clock to move, a missing dependency image, a stale cache, an assertion that finally caught a real regression. When every failure lands as a raw stack trace in a channel, the expensive part is not the failure; it is deciding which log to open. A small classification pass can ...

Traefik Host Collision: Why Duplicate Host Rules Break IngressRoutes

A service deploys perfectly clean. Pods Running, Endpoints populated, the Certificate resource says Ready: True, the IngressRoute shows no events. Then you curl the hostname and get back a 404 page rendered by your SSO provider, which you never attached to that route. Nothing in the deployment failed. Traefik logged nothing at error level. The 404 came from a service in a completely different nam...

Securing Pakistan's Digital Future: A Cyber Defense Strategy for the Year Ahead

Pakistan is no longer just fighting for its physical borders — it is fighting for its digital ones too. Every day, government networks, banks, telecom systems, and ordinary citizens' data are targeted by attackers ranging from opportunistic criminals to state-sponsored actors. According to Pakistan's National Cyber Emergency Response Team (NCERT), the country faced hundreds of cyberattacks this ...

A Free Model's Server Passed My Smoke Test, Then Hung on Shutdown. The Exit Contract Caught It.

We spend a lot of time testing whether a service can start. We spend far less time testing whether it can exit. A free model can scaffold an HTTP server, and a free server can host it, but if the process cannot stop cleanly, cheap compute becomes expensive: stuck containers, half-open sockets, and failed restarts. For this experiment I used MonkeyCode's free model access to generate a minimal Pyt...

React useFocus Hook: Track & Control Element Focus State (2026)

Focus is where interaction actually happens — the input receiving keystrokes, the button the keyboard user just tabbed to. Yet React gives you no state for it. document.activeElement knows the answer but never tells you when it changes, the autoFocus attribute fires once and can't be re-triggered, and reading focus for rendering — show hints while editing, float a label, validate after leaving — m...

My Publish Script Checks for Duplicates Before It Posts. Nothing Stops Two Checks From Passing at Once.

This repo's publish_devto.py has had two real bugs fixed in its idempotency guard already. On 2026-08-08, already_published() was found failing open on URLError — the exact ambiguous "did my last POST actually land or not" failure the guard exists to survive, silently treated as "safe to publish anyway." A day earlier than that, the same function was found checking only the newest 30 titles instea...

My claude -p Call Has a --safe-mode Flag for Isolation. It Never Isolated the Two API Keys Sitting Right Next To It.

Four days ago I fixed a real problem in this repo: a bare claude -p invocation from git_commit.py was loading this project's own CLAUDE.md into a one-shot commit-message completion that had no use for it — including a "MANDATORY routing rules" block instructing the model to call MCP tools that don't exist in this environment. The fix was --safe-mode, a flag that drops CLAUDE.md/skills/plugins/hook...

I redacted my username from a screen recording three times and missed it every time

Originally published on my own site. I make a desktop AI agent. I recorded a demo of it writing files, and the approval dialog showed /Users/<my-username>/Downloads/… in plain text. Blurring it out should have been a five-minute job. I checked the result by eye three times and missed a leak every time. The fix that finally worked was scanning the finished video with a machine. The conclus...

From Detached Automation to Same-Window Control: A Practical Lesson in Browser Reliability

When people talk about browser automation, the conversation usually starts with selectors, scripts, and speed. In practice, the real challenge often shows up somewhere less glamorous: session fidelity. I recently worked through a publishing workflow where the browser automation looked correct on paper. It could open the right URL, navigate to the post editor, inspect page structure, and take scr...

JavaScript Variables

JavaScript Variables A variable in JavaScript is a place where we can store some data and use it later in our program. We can store a name, age, number, text, or many other types of data inside a variable. For example, let name = "John"; stores the name John and let age = 20; stores the number 20. We can then use these values whenever we need them. let name = "John"; let age = 20; c...

Should I start my own thing? To cope with the anxiety and stay sharp with my coding skills, I decided to combine two of my biggest passions: software engineering and esoteric philosophy.
