Explaining JavaScript Promises and Async/Await for Asynchronous Code

·7 views

JavaScript is single-threaded, so long-running tasks such as server requests, file reads, and timers could freeze an app if handled synchronously. Asynchronous programming lets the language start such a task and keep running other code until the result is ready. Callbacks were the traditional approach but often produced deeply nested, hard-to-maintain code. Promises, which can be pending, fulfilled, or rejected, offer a flatter structure through .then() and .catch(), and async/await builds on them to make asynchronous code read more like synchronous code.

C++26 Introduces Contracts for Preconditions and Postconditions

A CppStories article provides an introduction to contracts, a feature slated for C++26 that lets developers express preconditions and postconditions in code. Preconditions describe what must hold true before a function runs, while postconditions describe what it guarantees on return. The piece explains how these checks help catch programming errors and document expected behavior. The source material available is limited to the article link and basic Hacker News metadata, so the full details of the feature's syntax and semantics are not included here.

Researchers say Israeli firm's digital ads enabled zero-click spyware installation

Security researchers allege that digital advertisements run by an Israeli company were used to install zero-click spyware on targeted devices. Zero-click attacks require no action from the victim, such as clicking a link, which makes them especially difficult to detect and defend against. The findings were reported by The Guardian in October 2026, based on the researchers' analysis. The article linked from the Hacker News post provides the full details of the alleged activity and the firm's involvement. The source material available here is limited to the link metadata, so specifics beyond these claims could not be verified.

Researcher reverse-engineers TikTok's x-argus anti-bot request signature

A developer published an account of reverse-engineering the x-argus signature TikTok's app attaches to its API requests. The token combines SM3 hashing with SIMON and AES encryption, and its logic sits in an obfuscated native library. The author reportedly bypassed static analysis by running the library under emulation with unidbg to produce valid signatures. The write-up says the resulting client can retrieve profiles, feeds and search results, and that the signature also depends on device fingerprint data and a specific TLS profile.

AI Hasn't Eliminated Deep Technical Understanding, It Has Made It Rare

A software developer recounts initially resenting AI tools, feeling that the hard-won understanding gained from years of debugging had suddenly been devalued. Advice from a mentor, comparing AI to an automatic gearbox, reframed the situation for the author. The core argument is that AI makes deep skill optional rather than worthless, so fewer people acquire it even as its value grows. The author warns that AI-generated code can look correct while hiding errors that only someone familiar with the underlying system can catch. The author concludes that the ability to recognize when AI is wrong is becoming the scarcest and most valuable part of engineering work.
