The web has evolved. Security issues in java and flash led to their removal from the web, which has meant a lot of applets created in java and flash no longer work. Scalable Vector Graphics (SVG) and Javascript are a poor replacement. But it can be powerful.
This site will evolve. The future is promised to no one. But at present it will center around SVG and Javascript, with an emphasis on engineering and maybe a little of falstad.
Issues are never simple. One thing I'm proud of is that very rarely will you hear me simplify the issues.
