PlayCode’s new online playground lets developers write, run, and prototype Python 3.12 code entirely in the browser—no installation, no server traffic, and full library support. The platform’s VS Code‑style editor, built‑in data‑science stack, and offline capability make it a compelling tool for both learners and rapid prototyping.

QEMU’s Tiny Code Generator (TCG) is the heart of modern emulation, translating guest CPU instructions into efficient host code on the fly. This article unpacks the translation pipeline—frontend IR generation, backend assembly, and block chaining—highlighting how QEMU balances portability and performance, with a concrete PowerPC‑on‑x86 example.

A developer demonstrates how a lightweight Python terminal can be run natively on an Android device, blending a Kotlin UI with a database backend. The experiment highlights the untapped potential of mobile terminals for on‑the‑fly scripting and raises questions about the future of portable development environments.

While developers focus on securing network communications, the silent vulnerability of insecure local data storage in IoT companion apps leaves sensitive credentials and operational data exposed. This deep dive examines how architectural flaws in mobile apps can compromise entire IoT ecosystems, using a smart lock companion app as a case study.

Node’s ubiquitous package ecosystem hides a silent menace: post‑install scripts that can read, write, and exfiltrate user data. While Deno’s permission model marks a step forward, it falls short without OS‑level isolation. The article explores how macOS’s sandbox‑exec can be leveraged to harden Node, and why the community must demand deeper sandboxing for JavaScript runtimes.

A new wave of the Shai‑Hulud supply‑chain worm has infected dozens of npm packages, from Zapier to Postman, exploiting post‑install scripts to harvest secrets and re‑publish malicious code. The attack, timed before npm’s token revocation deadline, demonstrates the escalating sophistication of ecosystem‑wide threats and the urgent need for hardened dependency pipelines.
