- mindcrime 8y agoRemember the "The Simpsons Already Did It" episode of South Park? I feel like all inventors have to have a similar "Nikola Tesla Already Did It" dread when they think they've invented something. Is there anything that guy didn't do?

- nickpsecurity 8y agoUnidirectional networks, or data diodes, are used extensively in high-assurance security for purposes like these: https://www.opswat.com/blog/why-data-diodes-are-essential-isolated-and-classified-networks https://www.opswat.com/blog/why-data-diodes-are-essential-is... Strongest designs are done with light such as fiber or infrared. A number of products were analyzed and pentested by evaluators and intelligence agencies with resulting EAL7+ certification, the highest. Link below lists some of the products. https://www.securitywizardry.com/index.php/products/boundary-guard/data-diodes.html https://www.securitywizardry.com/index.php/products/boundary...
