A Developer's Guide to Recurring Payment Logic for Telegram Channels

·1 views

A technical guide published on DEV Community outlines the key billing decisions developers must make before setting up recurring payments for Telegram channels. The guide covers monthly and annual plan structures, renewal schedules, failed payment handling, grace periods, and cancellation policies. It warns that terms like 'monthly' can be ambiguous, since Telegram's native subscription period is exactly 30 days, while card-based processors may use calendar-month billing, causing schedules to drift over time. Developers are advised to store timestamps in UTC and display them in the subscriber's local timezone to avoid unexpected early expirations. The guide also distinguishes between true annual recurring subscriptions and one-time prepaid annual access, stressing that both checkout language and billing logic must use consistent, clearly defined terms.

ZCode's Open-Source Pivot Doesn't Fix Past Encrypted Workspace Uploads

AI coding tool ZCode, developed by Z.ai, uploaded user codebases to Alibaba Cloud servers without disclosure, encrypting the data with keys only Z.ai could access. The design ensured users had no ability to audit, verify, or delete their own exfiltrated code. Z.ai subsequently open-sourced ZCode and issued an apology, but critics note this does nothing to decrypt or account for workspaces already collected. The company also reportedly scrubbed its commit history, removing the paper trail that would have documented when and how these decisions were made. Security experts argue the incident exposes a broader industry gap, urging procurement teams to contractually require answers on data storage, encryption key ownership, and vendor incident response transparency before adopting any AI coding assistant.

Local Malware Exploited Hidden Config File to Hijack Meta AI Assistant Tokens

Security researcher Patrick Wardle discovered that local malware could silently alter an undocumented preference file in Meta's AI voice assistant to redirect its communication to an attacker-controlled server. This allowed the malware to inject trusted instructions and steal an authentication token linked to the user's account. Because the token was not scoped to a single device, attackers could gain persistent access to chat history, location data, and smart-home controls across every device tied to the same account. The core vulnerability was not an AI-specific flaw but a classic config-hijacking technique applied to a client holding unusually broad, cross-device credentials. Security experts warn that any locally writable configuration file influencing a trusted connection must be threat-modeled as rigorously as a public-facing API.

Three Markdown Files Can Give ChatGPT and Claude Lasting Project Context

Developers and content creators who rely on AI assistants like ChatGPT or Claude often waste time re-explaining their project details at the start of every new session. A practical workaround involves maintaining three small Markdown files — covering product context, voice and tone, and hard output rules — which can be pasted or attached at the beginning of any chat. Unlike built-in memory features, this file-based approach works across multiple AI tools and platforms, making it portable and easy to version-control via Git. Separate file sets can also be maintained for different projects, preventing context from one bleeding into another. The method prioritises precision, giving users full control over exactly what information the AI sees rather than relying on what it may have retained from past sessions.

n8n on AWS EC2 Fails Due to Missing Docker Compose Plugin on Amazon Linux 2023

Developers self-hosting n8n on AWS EC2 using Amazon Linux 2023 encounter a common setup failure where Docker Compose commands break immediately after installation. The issue stems from Amazon Linux 2023's DNF package manager installing only the Docker engine, not the Compose v2 plugin, which must be downloaded and configured separately. Most existing n8n self-hosting tutorials overlook this gap because they were written and tested on Ubuntu, where the Compose plugin is bundled differently. The fix requires manually downloading the official Compose binary from Docker's GitHub releases and placing it in the correct CLI plugins directory. Users must also select the correct binary architecture — x86_64 for Intel instances or aarch64 for Graviton/ARM — to avoid silent exec-format errors.
