trelix v3.2.2 to v3.3.8: A GitHub App Already Hardened and Running in Production, and a Connector That Never Touches a Pixel

docker run --entrypoint trelix-mcp ghcr.io/sairam0424/trelix:3.2.1 --help returns exit code 127: command not found. Not a typo, not a stale tag — the published 3.2.1 image never contained trelix-mcp at all. The builder stage copied core trelix and nothing else, and .dockerignore 's blanket packages/ exclusion would have blocked the MCP package even if someone had remembered the COPY line. A second, unrelated defect shipped in the same release: the published trelix-mcp console script ...

Why our A/B testing tool refuses to call a winner

Two readings of the same experiment. Day 4. Variant B is up 12.7% on conversion rate. 12,506 visitors in the variant, 12,418 in control. The number is green. Somebody screenshots it and drops it in Slack. Day 11. Variant B is up 12.7%. Same test, same split, same traffic mix. Same experiment, same lift. The only thing that changed is how long it was allowed to run. One of those two readings is a result. The other is a coin that has come up heads four times. Every dashboard I have...

More RAM Changed What Matters in My Local AI Setup

Six months ago, I started running local LLMs seriously on a Mac with 16 GB of unified memory. Most of my decisions were dictated by memory: which models fit, which quantization to use, and how much context I could afford. Moving to 48 GB changed that. Models such as Qwen3.8-27B became practical for everyday use, and my attention shifted toward a different problem: how well does the model work during a real coding-agent session? Memory Was Only the First Constraint My curr...

Fathom Analytics vs Umami: Which Fits Your Website?

Fathom Analytics and Umami both make a credible case for privacy-conscious website measurement. The decision for a small website team is whether to buy a managed dashboard with little maintenance or run a broader analytics platform that can also be self-hosted. A third option, Clics, matters when the team wants the complete traffic-to-conversion picture and a separate record of verified AI crawler requests. The comparison below uses the same requirements for all three: setup, acquisition repo...

Linux Security Is More Than Root: Syscalls, Capabilities, Namespaces, eBPF and AI-Assisted Privilege Escalation

Linux Security Is More Than Root: Syscalls, Capabilities, Namespaces, eBPF and AI-Assisted Privilege Escalation For a long time, Linux security was explained with a simple model: user → process → root That model is still useful. It is also incomplete. A modern Linux application can interact with the kernel through syscalls, operate inside multiple namespaces, hold individual capabilities instead of full root privileges, be restricted by seccomp, pass through LSM controls, inter...

I Built a Better Codex Pet Than OpenAI Did

Sometimes you just have to let the agent cook. Mika vs. a multi-billion-dollar corporation, and a stupid little desktop pet. When OpenAI shipped Codex Pets in May 2026, they wanted to give your coding agent a face. The pets float as an overlay on Windows and macOS, showing real-time status updates about what Codex is doing, and can notify users when a task completes or when the agent needs input. The feature launched with eight built-in pets and a way to generate custom, AI-an...

Cambio vs. Agentic Wallets: Different Problems, Different Solutions

2026 is the year agentic wallets — Bankr, deBridge's MCP server, Brian, Coinbase Smart Wallet — went mainstream. They put an AI agent inside the user's wallet. Cambio takes the opposite approach: the agent lives in our composer, the user's wallet stays untouched. Here is why both can be right, and which one is right for which job. Two categories of "AI in crypto" went mainstream in 2026. The first is agentic wallets: products like Bankr, the deBridge MCP server, Brian, and Coinbase Smart Wall...

The Snippet List I Hand to Contractors Before Their First Commit

When a contractor joins a project for a week or a sprint, the onboarding problem isn't the code — it's the context . The code is in the repo. The context is in the heads of the people who've been here a year, and it doesn't transfer in a wiki page. I've stopped writing wiki onboarding pages. Instead, I hand the contractor a snippet list — a curated set of the commands, configs, and one-liners they'll actually need in the first 48 hours, stored in snippetx and shared as a plain-text expor...

Can an ‘eSUV’ e-bike really go from trail to town?

Have you ever wanted an electric bike that easily transitions from the drudgery of urban asphalt to adventures in gravel and dirt? That's what a subclass of so-called "electric SUV" (eSUV) e-bikes claims to do, with their wide, all-terrain tires and front and rear suspension, plus practical accessories like fenders and racks. So, that's what […]

How ACME HTTP-01 and DNS-01 Challenges Work Internally

Automated TLS certificate issuance looks simple from the outside. An ACME client requests a certificate, a certificate authority creates a challenge, the client proves control of the requested domain, and the CA issues the certificate. Once the process has been automated, certificate renewal can happen without an administrator manually generating a CSR, uploading validation files, or downloading a replacement certificate. The interesting engineering problem is what happens between those steps...

Apple Pay Token Decryption vs Google Pay ECv2

Apple's own reference page for decrypting an Apple Pay token currently gets the key derivation wrong. The KDF table lists the hash function where the shared secret should be, and it has dropped the id-aes256-GCM algorithm ID bytes altogether; the archived version of the same page has the correct values. If you are building a decryptor from the live docs, you will get a key that never opens the ciphertext, and nothing in the error will tell you why. That is the level most "decrypt Apple Pay ...

How to Create a BOM (Bill of Materials) for Your Android Libraries

As Android developers, we use BOMs every day. Every time you add platform(libs.firebase.bom) or platform(libs.compose.bom) to your build.gradle.kts , you're importing one. A BOM lets you drop a single version into your build file and get a set of libraries that are guaranteed to work together.
