Six Mail Exchange Setup Checks for Provider Records and Forwarding Hosts

Publish the mail provider's MX records with explicit, distinct priorities, and keep a forwarding host only as a temporary migration control. The deciding constraint for a fintech product is evidence: when a customer says mail disappeared, the on-call engineer needs to reconstruct where an SMTP sender was told to go, which system accepted the message, and whether the domain separately authorized outbound mail. Short answer: an MX cutover is ready when six checks agree: the intended records exi...

Logging Out All Devices Did Not Log Them Out: Session Revocation Done Properly

-- title: "Logging Out All Devices Did Not Log Them Out: Session Revocation Done Properly" description: "Logging out of all devices clears one kind of credential.

How to tell them apart, the order to revoke in, and what to re-check afterwards." tags: ["security", "privacy", "twitter", "howto"] canonical_url: https://digital-fo...

What Building SupportMind Taught Us About AI Agents

Hackathons have a way of turning simple ideas into surprisingly interesting engineering problems. Our starting idea sounded straightforward: Build an AI customer-support agent that remembers customers. Then we started asking questions. What exactly should it remember? How does it retrieve the right memory? How do we prevent customer histories from mixing? What happens when there is no memory? How do we show that memory actually improved the response? Those questions sh...

SupportMind: A support agent that remembers every customer

What If Customer Support Actually Remembered You? ai #customersupport #agents #llm “Please explain your issue.” Few sentences are more annoying when you already explained the issue yesterday. You give your account details again. You describe the problem again. You list everything you've already tried. Then you receive the same troubleshooting steps. For our hackathon project, we asked a simple question: What if customer support could remember? That questio...

Gerrit Code Review on the Open Internet: 2,508 Title Matches and the Credential Store Behind Them

Gerrit Code Review on the Open Internet: 2,508 Title Matches and the Credential Store Behind Them Why a code review server is a credential store Gerrit sits between developers and a Git repository. To do that job it holds credentials for the repository, for the continuous integration system, for the database that stores review metadata, and often for an identity provider. An administrator who authenticates to Gerrit can push code into the repository it manages and can read the r...

Image Upload Gatekeeping: 4 Metadata Checks for Early Express Rejection

Short answer: inspect the upload stream before durable storage, reject on byte count first, then parse trusted image metadata and enforce pixel limits. In a marketplace, that small gate catches oversized listings before moderation workers and object storage have to touch them. Gate What it proves Action Declared length A client-side hint only Never trust it alone Received bytes Transport size Stop at the hard byte cap Format signature The parser's in...

Build a Voice-Enabled Chatbot with ElevenLabs and OpenAI

Why a Voice‑Enabled Chatbot? Chatbots have become the go‑to interface for customer support, personal assistants, and even hobby projects. Adding a voice layer turns a static text bot into a more natural, hands‑free experience. With the rise of powerful large‑language models (LLMs) and high‑quality text‑to‑speech (TTS) services, you can spin up a voice‑first assistant in a single afternoon. In this guide we’ll stitch together OpenAI’s GPT‑4 for conversational intelligence and ElevenLabs...

AI Can Write Code Fast, but Testing Is Still the Bottleneck

AI has changed the way I work on my mini-game. With tools like GPT, Gemini, and Codex, I can implement features much faster than before. I use AI to help write code, generate configurations, review logic, fix compilation errors, design game mechanics, and maintain documentation. Recently, I used AI to work on different types of enemies and bosses. Features such as speed bursts, armor changes, summoning, healing, and different boss behaviors can now be implemented surprisingly quickly. A...

Knight Capital: how a reused feature flag lost $460 million

On August 1, 2012, Knight Capital, the firm behind about a tenth of all U.S. stock trading, deployed new code to seven of its eight order-routing servers. The eighth still had code the company had retired in 2003, behind a feature flag the new code reused. In 45 minutes it executed 4 million trades and left Knight with a loss of more than $460 million. The best postmortem of it was written by the regulator, and every lesson in it still applies to anyone who ships with feature flags. ...

Voice AI for Accessibility: Making the Web More Inclusive

Why Voice AI Matters for Web Accessibility When you think of web accessibility, the first things that come to mind are screen readers, keyboard navigation, and ARIA labels. Yet a huge portion of the web still relies on visual cues and text that can be hard to consume for people with low vision, dyslexia, or cognitive challenges. Voice AI—especially high‑fidelity text‑to‑speech (TTS) and voice cloning—can level the playing field by turning any page into an audio experience that feels natural,...
