I am the developer of soldirac.com.
Thanks for bringing this in, I pushed a major update last night so a few things broke down during hotfixes. I have fixed the bug now thanks to the guy who report it to me on reddit.
I would like to take this thread to explain further about soldirac. It is not a dead project. I work on in during free time. Although the progress has been really slow and I'm always looking for more people to get involved.
to reply to @kilianbuhn - It IS possible to fund your own question. Anyone can add to the bounty of a problem with the "Boost" option. That is also the primary source of income for soldirac because the website automatically takes 10% of a boost amount, this helps fund other questions.
Ads on the other hand have almost zero revenue.
