Developer Adds Go-Style Defer Statement to TypeScript Compiler

·1 views

A developer has experimented with implementing Go's 'defer' keyword into the TypeScript compiler. The 'defer' feature, native to Go, allows functions to be scheduled for execution at the end of a surrounding function's lifecycle. The project involved modifying TypeScript's compiler internals to support this behavior. The work is documented in a technical write-up published on the developer's personal blog. The experiment highlights growing interest in borrowing control-flow features from Go into other statically typed languages.

How to Call Real Phone Numbers from a Browser Using WebRTC and SIP

A developer guide explains how to connect browser-based WebRTC audio to the public telephone network (PSTN) using a SIP telephony provider such as Telnyx. The architecture involves three components: the browser capturing audio via WebRTC, a telephony provider bridging WebRTC to traditional phone infrastructure, and a backend server that issues short-lived credentials. A key security rule emphasized throughout is that API keys must never reach the browser — only a JWT token of limited duration is sent to the client. The guide also highlights non-obvious billing and timing quirks, such as zero-second calls appearing on invoices and CDR rounding mismatches. Virtual phone numbers can be purchased and configured programmatically via REST API as part of the same setup.

AI Chat Assistants Vulnerable to Transcript Injection via Browser DevTools

A security flaw affecting many production AI chat assistants allows attackers to manipulate conversation history directly from a browser's network tab, requiring no prompt engineering or special tools. The vulnerability stems from a common implementation pattern where the client sends the entire message history to the server on every turn, meaning all messages — including those claiming to be from the assistant — are effectively user-controlled input. By injecting fabricated assistant turns, an attacker can make the AI model believe it has already verified a user's identity or granted elevated permissions, bypassing content filters entirely since no suspicious language is used. The root cause is that AI models treat assistant-role messages as trusted records of what actually occurred, making forged history more convincing than traditional jailbreak prompts. The fix is straightforward: servers should retrieve conversation history from their own database rather than accepting it from the client, accepting only the latest user message per request.

Developer Recreates Jollof Rice in Pure CSS for Frontend Art Challenge

A developer named Eze-Charles submitted a CSS art piece depicting a bowl of jollof rice as part of DEV Community's Frontend Challenge - Comfort Food Edition. The artwork was built entirely with CSS, using no images or SVG assets of any kind. Rice texture was achieved through layered radial gradients at varying sizes, while steam effects were created using four blurred circles. The creator noted that the steam animation was the element they were most proud of in the project. Looking ahead, the developer plans to attempt a second CSS dish featuring liquid movement or a pour animation.
