Source: 50 Shades of Rust, or emerging Rust GUIs in a WASM world

Summary
GUI in Rust is advancing rapidly, exceeding the speed of development in the web. Due to cross-platform capabilities, Rust GUI is utilizing WebAssembly support for easier software distribution. This blog post reviews the current toolkit for GUI in Rust and shares tips for building WebAssembly bundles.

Fact

💻 Dioxus has global state management through a useContext-like API and its reactive semantics allow for easy integration of Redux-like tools.

🌐 Tauri is a toolkit for building fast and secure native apps with a smaller footprint than Electron.

🎨 Iced provides an intuitive and productive way of creating GUI applications with a simple syntax and efficient execution.

🕸️ Yew uses Rust infrastructure to create web applications, providing similar syntax for both client and server-side programming.

🚀 OrbTk focuses on modularity, allowing users to choose the features they need and has a widget system designed to create hi-fi user interfaces.

Source: The KRC-2 regenerative receiver kit: a review

he assembly is to adjust the regeneration control. This is done by tuning the radio to receive a strong signal, and then adjusting the control until the signal reaches maximum strength. It’s a delicate balance between too little regeneration (no amplification) and too much (overloading and distortion).Summary
The KRC-2 regenerative receiver kit is a good choice for those interested in building a regenerative radio. The instructions are easy to follow and the design maximizes the width of the traces and the area for solder pads.

Facts

🔌 The KRC-2 regenerative receiver kit takes about 3 hours to assemble.

🔬 The copper side of the “regenerative board” is isolation-routed, which makes it more likely to produce a successful PCB than if you try to lay it out like a normal PCB.

📻 The KRC-2 receiver is an unusual regenerative receiver because it uses a 10.7 MHz oscillator mixed with the incoming signal from the antenna.

🔊 The speaker is glued to the back of the front panel with PVA glue which, although it seems to have stuck well enough, may cause problems if the radio needs to be taken apart in the future.

🎛️ The regeneration control needs to be delicately balanced to avoid too little regeneration or too much, which can cause overloading and distortion.

Source: Now They’re Trying Censor Your Text Messages

Summary
The Omidyar Foundation, led by eBay founder Pierre Omidyar, has advocated for spying on and censoring encrypted private messaging. Their January 2022 report suggests using tiplines to identify potentially misleading content on platforms like WhatsApp, and a “think tank” called Meedan created a project called CryptoChat to hunt down wrongspeak on encrypted chats. Critics argue against this infringement on privacy.

Fact
💬 The Omidyar Foundation suggests creating tiplines to identify potentially misleading content on WhatsApp and other encrypted platforms.
🕵️‍♀️ Meedan, an anti-disinformation partner of Twitter, created a project called CryptoChat to spy on encrypted chats for wrongspeak.
🔒 Wired advocated for spying on private messages in the name of preventing harm, arguing that features like convenience and speed have fueled abusive and illegal behavior.
👥 Social media companies responded to 75% of flagged posts from the Censorship Industrial Complex and acted on one-third of them.
❌ Critics argue against the infringement on privacy and censorship of encrypted private messaging by the Omidyar Foundation and other organizations.
