Developer Releases REST API to Convert Videos into Telegram-Compliant Avatars

·1 views

A developer has launched a public REST API for LiveAvaBot, a tool originally built to solve Telegram's strict video avatar format requirements. Telegram video avatars must meet specific technical constraints — H.264 codec, 800x800 resolution, under 2 MB, and MP4 with a faststart flag — which silently reject common iPhone HEVC videos. The bot, which has served 290 users since launching last year, uses an ffmpeg pipeline to automatically crop, re-encode, and optimize videos to meet these specs. After multiple developers requested programmatic access for use cases like profile-picture flows and cross-platform bridges, the creator exposed the conversion pipeline via a REST API endpoint. The API accepts multipart video uploads with optional visual presets and handles the full conversion process server-side.

Why Real-Time Fraud Prevention Is Critical for Instant Payment Systems

The rapid adoption of instant payment networks like FedNow, RTP, and UPI has fundamentally changed how fraud and risk must be managed, as transactions now settle in seconds with no window for manual review. Unlike traditional systems that allow batch processing and post-settlement checks, instant payments require all fraud detection and compliance decisions to be made within milliseconds. Key threats facing these systems include account takeover, authorized push payment fraud, transaction velocity attacks, and synthetic identity fraud. Developers are advised to build risk management directly into payment architecture from the start, using real-time risk engines that evaluate behavioral, device, and transaction data before approval. The shift demands a move from reactive fraud detection to proactive, automated risk prevention to protect both users and platforms.

AI Audit Thriller Series: Alex and Derek Uncover Suspicious Network Scanning Activity

In episode 23 of the Stratagems fiction series on DEV Community, security analyst Alex detects unusual high-density network scanning originating from Singapore and targeting a MedTech test environment. The scanning pattern, including its traversal order and exclusions, matches behavior Alex and colleague Derek had previously used when tampering with ACL's audit pipeline. A device fingerprint not listed in MedTech's asset inventory briefly reappears in the mirror logs before vanishing within seconds. Derek, reviewing the MediSys test side, finds that ACL appears to be actively hunting for whoever interfered with their pipeline. The episode ends with Derek warning that he believes ACL's investigation has him in its sights.

Design-First AI Workflow Cuts Debugging Time by Clarifying Scope Upfront

Many developers in 2026 default to ad-hoc AI prompting — typing requests on the fly and iterating through errors — rather than defining requirements before engaging a model. A design-first approach involves writing a structured brief covering inputs, outputs, constraints, and edge cases before issuing any prompt to an AI coding assistant. McKinsey's 2024 State of AI report found that organizations using structured planning before AI implementation report higher success rates than those relying on improvised strategies. By treating the AI as a contractor given a clear scope rather than a real-time collaborator, developers shift early exchanges from scope clarification to code review. The method is especially effective for constraint-heavy tasks, where precise upfront specification produces near-final output on the first pass.

Dev builds puzzle game rule through four failed fixes before it finally works

A developer working on a puzzle game called Traceroute documented the iterative process of implementing a single path-completion rule in their third devlog. The rule required that clicking through a color's endpoint should stop the path there and mark it as complete, but the first three attempts each solved only part of the problem while hiding the next flaw. Early fixes addressed the path not stopping and a misrouted rejection animation, but the stop turned out to be cosmetic, with no underlying lock preventing further path extension. The real solution was freezing the entire path upon reaching the endpoint, which also immediately raised a new design question: what if the locked path was unintentional. This directly led the developer to build undo, redo, and clear functionality as necessary consequences of the freeze mechanic rather than optional features.
