Backdoor Found in ESP32 Chip Threatens Millions of IoT Devices

Tarlogic Security researchers revealed at RootedCON an undocumented backdoor in the ESP32 microcontroller, used in millions of IoT devices. This vulnerability allows attackers to bypass code audits, impersonate devices, and permanently infect smartphones, computers, and smart locks. To address this, Tarlogic also unveiled BluetoothUSB, a free tool to simplify Bluetooth security audits. The discovery highlights the critical need for robust IoT security and underscores the importance of accessible security tools.

Pixel 4a Battery Update Disaster: Old Firmware Gone, Users Trapped

Google's Pixel 4a battery performance update has turned into a disaster. The update is causing extreme battery drain for many users, and worse, Google removed the older firmware, making it impossible to roll back. Intended to improve battery life, the update has instead made things significantly worse. Affected users are left with Google's compensation offer: a free battery replacement, $50 cash, or a $100 credit towards a new Pixel. This incident highlights the risks of software updates and Google's shortcomings in handling updates for older devices.

The Demise of the 80x25 Text Console in Modern Linux

2025-09-17

The author encountered a frustrating issue: the classic 80x25 text console, a feature present in DOS, OS/2, FreeBSD, and Linux for over 40 years, is largely gone in modern Linux systems. This isn't simply a resolution problem; it involves UEFI booting, non-x86 platforms, and the shift to graphical rendering modes. Old solutions like the `vga=` parameter are ineffective, and newer attempts like using `kmscon` have significant issues. The author is resorting to finding an older PC, highlighting the declining compatibility between modern systems and legacy hardware.

Tokyo Offers Free Daycare to Combat Plummeting Birth Rate

Facing a persistent decline in birth rates, Tokyo is launching a bold initiative: free daycare for all preschool children starting September next year. This move aims to improve work-life balance and incentivize childbirth. While Tokyo previously implemented a four-day workweek, this free daycare plan is broader, encompassing all children unlike previous programs which only covered second children. Although the exact cost remains undisclosed, the Tokyo governor emphasizes the urgency of addressing the demographic crisis.

Bun: Why Package Installs Are 7x Faster Than npm

2025-09-11

Bun package manager is renowned for its blazing speed, averaging ~7x faster than npm, ~4x faster than pnpm, and ~17x faster than yarn. This isn't magic; Bun treats package installation as a systems programming problem, not a JavaScript problem. It achieves this through minimizing system calls, caching manifests as binaries, optimizing tarball extraction, leveraging OS-native file copying, and scaling across CPU cores. The article delves into how Bun, written in Zig, bypasses Node.js's limitations (thread pool, event loop) to achieve incredibly fast package installations.

How Interruptions Impact Software Engineers: A Research Deep Dive

New research explores how interruptions affect software engineers' productivity and stress. The study found that different types of interruptions (e.g., in-person vs. on-screen notifications) impact coding, code comprehension, and code review differently, with complex tasks being less affected. Interestingly, physiological data (heart rate variability) showed less stress with in-person interruptions, but engineers perceived them as more stressful. Managers should prioritize engineers' perceived stress, minimizing high-priority interruptions and providing focused time for tasks like coding to boost team efficiency.

GM Forces Dealer to Halt Aftermarket CarPlay/Android Auto Kit for Ultium EVs

GM Forces Dealer to Halt Aftermarket CarPlay/Android Auto Kit for Ultium EVs

General Motors (GM) forced a dealer to discontinue an aftermarket kit that restored Apple CarPlay and Android Auto phone mirroring in its Ultium electric vehicles. This follows GM's decision in December 2023 to remove CarPlay and Android Auto support from Ultium EVs, opting for its own in-vehicle infotainment systems in future models. While the kit's manufacturer, WAMS, claims rigorous testing, GM's action sparked industry criticism, as a study showed nearly half of car buyers wouldn't purchase vehicles lacking CarPlay or Android Auto. GM is effectively pushing dealers towards its built-in systems, leaving little alternative.

Claude vs. ChatGPT: A Tale of Two Memory Systems

This post compares the drastically different memory systems of Claude and ChatGPT, two leading AI assistants. Claude starts each conversation with a blank slate, searching conversation history only when explicitly invoked using `conversation_search` and `recent_chats` tools for keyword and time-based retrieval, offering a powerful tool for professionals. In contrast, ChatGPT, designed for a mass market, automatically loads memory components, building user profiles and providing instant personalization. These design choices reflect the different target audiences (professionals vs. general users) and product philosophies (professional tool vs. consumer product), highlighting the vast design space and future directions of AI memory systems.

SpaceX Falcon 9 Launch Scrubbed 11 Seconds Before Liftoff Due to Delta Air Jet

A SpaceX Falcon 9 rocket launch was scrubbed with just 11 seconds to go on Sunday morning after a Delta Air Lines plane reportedly flew into restricted airspace near the launch site. The live broadcast of the launch showed the control room urgently calling "Hold, hold, hold!" as the launch was aborted at the 11-second mark. Investigations revealed the Delta Air Lines Boeing 767, en route from Los Angeles to Honolulu, flew over Vandenberg Space Force Base, the Falcon 9 launch site. The Federal Aviation Administration (FAA) will investigate how air traffic controllers allowed the Delta flight to enter the restricted airspace. This near-miss comes days after SpaceX's Starship rocket exploded, causing flight diversions.
