Drowning in Slop - A thriving underground economy is clogging the internet with AI garbage-and it's only going to get worse.

SLOP started seeping into Neil Clarke's life in late 2022. Something strange was happening at Clarkesworld, the magazine. Clarke had founded in 2006 and built into a pillar of the world of speculative fiction. Submissions were increasing rapidly, but “there was something off about them,” he told me recently. He summarized a typical example: “Usually, it begins with the phrase ‘In the year 2250-something’ and then it goes on to say the Earth’s environment is in collapse and there are only three scientists who can save us. Then it describes them in great detail, each one with its own paragraph. And then—they’ve solved it! You know, it skips a major plot element, and the final scene is a celebration out of the ending of Star Wars.” Clarke said he had received “dozens of this story in various incarnations.”

Understanding Mesh Circuits How to Use and Calculate Them

Microcontrollers and other digital systems concern mostly ones and zeros but when connections to the real word are needed it can get messy. Stuart writes about mesh analysis and how mesh circuits can be calculated and applied in practical scenarios.

Suspenseful and deliciously unsettling, Entitlement examines the seductive pull of money and its ability to warp our perspectives.

Retro-style Miniature Sports Scoreboard - RGB LED Matrix and Raspberry Pi Provide In-Game Updates

This Cornell University graduate describes how he built a miniature, retrostyle scoreboard that pulls and displays live college and professional sports scores from the ESPN API-bringing the excitement of being at a sporting event to your living room. Pre-game information, in-game scores, and post-game results are displayed on a built-in PiTFT touchscreen.

No Blues with Bluetooth! GATT Explained - Part 5 - Understanding Higher Protocol Layers Provides Interoperability Help

After exploring low-level layers of Bluetooth Low Energy in previous editions, and establishing connections in Part 4, Robert examines Attribute Protocol and Generic Attribute Profile or GATT in Part 5. These higher layer protocols provide developers with greater opportunity for interoperability with third-party applications or products.

Power Analysis Over JTAG Ports: Hidden Debug Dangers - Block Side-Channel Analysis Attacks

Small changes in the phase of clock signals can encode power leakages. An attacker can use standard interfaces such as the JTAG port to drive clocks across targets, using them as measurement techniques for sidechannel analysis attacks despite limited physical access. This article demonstrates how you can test devices for vulnerability and how to modify devices to prevent attacks.

Mobile APP Development with React Native

This month, Bob continues his series on mobile app development from an embedded designer's perspective. He programs a React Native app and he offers guidelines for picking a tutorial for React Native. He further explores how it handles concurrency and asynchronous programming. Bob expected a few nuances during the process but to say there were more than a few would be an understatement.
