We at MathBlog have written about a couple of problems from the UVa Online Judge. The current UVa OJ platform is almost 7 years old, and so the UVa OJ team thinks it’s time for an upgrade. They intend to build the platform up from scratch, but to do that, they need funding. Therefore, they’ve set up a campaign, located here, where you can donate and help fund the project. Note that MathBlog is not affiliated with UVa Online Judge in any way.
There are 6 days left of the campaign, so we encourage you to let others know, and perhaps even donate yourself.
