And suddenly your sig is gone again.  Looks like the Einstein forum program is playing up.

If this page takes an hour to load, reduce posts per page to 20 in your settings, then the tinpot 486 Einstein uses can handle it.

I can make the sig work using Boincstats png.  All I did was in Einstein, go to preferences, community.  Then in the signature box I press the image button (far right), and enter the URL https://www.boincstats.com/signature/-1/user/926/sig.png (change that to your one, that one is Dan's), then press ok and save.

Oh, I tried the image link

Oh, I tried the image link button several times, it never worked for me either.  What works is to NOT use either the link or image link button as that invokes the forum formatting.  I just use the standard BBCode syntax, straight in the input box and Save.  That is all that is needed.

The image link worked for me just fine.  Maybe the forum had some problems.  You used to have a working sig, they must have screwed something up temporarily.

I guess either they're understaffed due to the virus, or there was a big technical problem, or it's a low priority project and they're concentrating on gamma and gravity.

 

From what I remember being said when they turned off the PC part of the project* I suspect it's only still running at all because none of their other apps scale down enough to run on arm systems.

 

*  No more data from Parks and just a tricle from Arecibo.  While running the search deeper by increasing the distance between binary members being searched for increases the amount of work needed to be done by r^3, while more distant binaries are increasingly rare.  Until GPUs got much faster than they were then the sharply diminishing returns meant that the Fermi project would find a lot more neutron stars.  And while GPUs have gotten a lot faster over the intervening years, the Fermi app has also gotten a number of speedups, and they're working on a GPU powered GW search; so the science returns from running it instead of something else still aren't here.  

 

OTOH unlike the GW search which needs a massive amount of post-processing to put individual results together and look for a potential result the BRP and Fermi searches return something much closer to individual found/not found results, so having the validator keep an eye out for a chance positive result worth a brief publication doesn't really cost them anything.  And leaving it running does confirm that they haven't accidentally broken the data processing pipelines and could turn it on again if there was a need (less of a concern now that the GW GPU app is there to backstop Fermi as a source of work).
