Finding the Right Case to Protect Your Raspberry Pi - Make Tech Easier
Raspberry Pi boards, including the popular Raspberry Pi 4, the Raspberry Pi 3B, and the Pi Zero W, are often sold without cases or covers to house your builds. That means if you want to protect it from the elements or make it look more polished, you’ll either have to buy or make your own case. This article will help you decide what options are available and which case is best for your Raspberry Pi.

A Secret Apple Silicon Extension to Accommodate an Intel 8080 Artifact
Rosetta 2 is the ahead-of-time compile translator that’s part of macOS Big Sur (and later) that, upon launch of an x64 Intel binary, translates it to 64-bit ARM code for execution on ARM-based Apple Silicon processors before execution. It is not a real-time emulator. It translates the entire binary — once — at launch time, making best-guess choices along the way. Dougall delves into various aspects of Rosetta 2 in an effort to explain why it is so performant; in many instances the translated binary runs faster on Apple Silicon than on the fastest Intel machines that Apple has ever released. It’s impressive.

Why is Rosetta 2 fast?
Rosetta 2 translates the entire text segment of the binary from x86 to ARM up-front. It also supports just-in-time (JIT) translation, but that is used relatively rarely, avoiding both the direct runtime cost of compilation, and any indirect instruction and data cache effects.
Other interpreters typically translate code in execution order, which can allow faster startup times, but doesn’t preserve code locality.

Time to Speaker Up!
Hello everyone and welcome back to another Friday Product Post here at SparkFun Electronics. This week, we have a brand new audio-based kit, the Qwiic Speaker Kit! This simple box of goodies provides you with just what you need to get started with stereo audio via a simple Qwiic interface! Following that, we have a new version of our Micro OLED Breakout, but with pre-soldered headers.

Air32F103 is a clone of STM32F103 clocked at up to 216 MHz - CNX Software
Air32F103 is yet another clone of the STM32F103 microcontroller that can be faster if needed with a clock of up to 216 MHz instead of 72 MHz for the original STMicro STM32 Arm Cortex-M3 microcontroller.
The first SKU of the family is the Air32F103CBT6 whose peripherals and hardware design are compatible with equivalent STM32F103CBT6 parts and offered with 32KB RAM and 128KB flash. There’s also a Bluepill-like development board, but with a different pinout, made by LuatOS.
