Anyone who cares about security may be interested in a new open source entropy generator, which was created by Paul Campbell in Otago and called OneRNG. OneRNG has been designed to create specifically generated random numbers, the system can use cryptography, and is completely open source, secure but abridgeable.
OneRNG is an entropy generator that produces a long list of random bits from two separate noise sources that can be used to seed your operating system's random number generator and then use this information to create the keys you use when you Visit websites, or use encryption systems like SSH and PGP, and transparency is important.

A Pu system for shoe soles refers to the use of polyurethane (PU) material in the manufacturing of shoe soles. PU is a versatile and durable material that offers several advantages for shoe soles.
Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
