How to Build a Production-Ready Telegram Bot API Client in Yii2

·1 views

A technical tutorial published on DEV Community walks developers through building a structured Telegram Bot API client within the Yii2 PHP framework. The guide emphasizes using a dedicated TelegramClient component that extends Yii2's base Component class, integrating with its dependency injection container and logging infrastructure. It addresses common pitfalls such as hardcoded credentials, unhandled HTTP 429 rate-limit errors, and scattered cURL calls by introducing a clean abstraction layer. Sensitive bot tokens are isolated in a local configuration file excluded from version control, keeping credentials out of the codebase. The tutorial focuses solely on the outbound HTTP transport layer and does not cover database models, migrations, or webhook routing.

5 Beginner JavaScript Projects to Build Real Coding Skills

Learning JavaScript improves significantly when beginners apply concepts through small, practical projects rather than just studying topics in isolation. Recommended projects include a to-do list, a calculator, a product filter, a quiz app, and a weather app using a public API. Each project targets specific skills such as DOM manipulation, array handling, async programming, and event management. The suggested learning cycle — build, test, break, fix, and improve — is emphasized over passive tutorial watching. Starting with a basic working version of any one project is encouraged as a more effective path to progress.

Claude.md Files Should Stay Under 200 Lines to Keep AI Instructions Effective

Anthropic's documentation recommends keeping CLAUDE.md files under 200 lines, as longer files consume more of Claude's context window and reduce how reliably the AI follows instructions. The 200-line figure is a soft target, not a hard limit — the file still loads beyond that point, but adherence gradually degrades. A separate hard limit of 4 MiB exists, at which point Claude Code skips the file entirely, though plain text rarely reaches that threshold. Developers using subagents should be especially mindful of file length, since each subagent loads CLAUDE.md into its own context, effectively multiplying the token cost. When a file grows too long, the guidance suggests trimming unnecessary content, splitting instructions across multiple scoped files, or moving reference material such as API docs to external links.

Arbitrum Bridge Rated 7/10 Risk as $3.28B TVL Faces Centralisation Concerns

A DeFi security audit dated September 13, 2026, assessed the Arbitrum Bridge, which currently holds approximately $3.28 billion in total value locked, representing around 12% of all assets on the Arbitrum network. The report flagged significant centralisation risks, noting that four of the seven validators on the committee are owned by the same parent company, raising concerns about potential collusion. Over 80% of the bridge's liquidity is concentrated among a small number of whale addresses and a single Uniswap V3 pool, amplifying systemic risk if major participants exit. Additional vulnerabilities include a seven-day fraud-proof window that could be exploited before a challenge is mounted, an upgradeable contract governed by a multi-sig with overlapping control, and the absence of any liquidity insurance mechanism. The overall risk profile was rated moderate-high at 7 out of 10, with auditors warning that adversarial conditions could result in substantial user fund losses.

LOOK: New Single-Binary Programming Language Built to Simplify Web Backend Development

Developers have introduced LOOK, a web-focused programming language and runtime built using C++23, designed to reduce the complexity of modern backend stacks. Rather than relying on separate frameworks, servers, and libraries, LOOK bundles HTTP, routing, WebSocket, database access, authentication, caching, and other core capabilities into a single distributable binary. The project aims to eliminate the need for multiple independent components that are typically required before any application logic can run. LOOK uses a bytecode-based virtual machine with a register-based execution pipeline, and also includes a tree-walking interpreter for development and benchmarking purposes. The language is purpose-built for web backend use, distinguishing it from general-purpose languages that adopt web frameworks as an afterthought.
