Yep.

I've dug a bit into this since I last posted about this over at MW and an important thing I've realised is that user (contributor) â‰ profile

A profile needs to be created by a user before they can be verified by an admin and become eligible for UOTD. A vast majority of folks have not created a profile, even if they do know where to do this (for instance, using the user search function, of the 89 users who have signed up since July 1st, only one user has created their profile). You, arcturus (user=3687), for instance, do not have a profile and cannot be UOTD unless you create one.

I've created a profile today and I reckon once valterc approves this, I'll be UOTD.

If there are no verified profiles that meet the minimum criterion for UOTD (i.e., average credit > 1 and hasn't been a UOTD previously), a random profile from a pool of the oldest 100 UOTDs is selected to be the UOTD (again). I suspect this is the reason you're seeing old, inactive UOTDs in many projects as the pool of fresh profiles is very small, if not depleted. The reselection criterion does not check for average credit and I do not see a "safe" way (i.e., via project config) to change this unless this line in the BOINC server code is changed and/ or this is enhanced to give the project owner better control of the criteria via project config:

$inner = "SELECT profile.userid FROM profile,user WHERE profile.userid=user.id AND verification=1 AND uotd_time>0 ORDER BY uotd_time ASC LIMIT 100";

$inner = "SELECT profile.userid FROM profile,user WHERE profile.userid=user.id AND verification=1 AND uotd_time>0 AND expavg_credit>1 ORDER BY uotd_time ASC LIMIT 100";

PS. Not a BOINC developer or a project maintainer so all of this is purely observational and may be incorrect.

Thanks, I'll keep a look out for any such cases in the future.

I've noticed about a dozen of my tasks have failed validation ("Completed, marked as invalid"). These are non-overclocked stable clients. In all cases, I see the task that was marked as invalid was stopped and then started using a checkpoint. E.g.,
Task 72335483 - Start from checkpoint: 266
Task 73023296 - Start from checkpoint: 600

Is there a known problem where tasks that start from a checkpoint fail to produce valid results?

I also noticed this in another BOINC project (although the client that produced the invalid result from a saved checkpoint wasn't mine). Is checkpointing handled differently by each BOINC project or is it a standard functionality offered by the BOINC platform?

The science stats page now has a column for the ETA. Thanks, @valterc!

From the science stats page,

H. sapiens (Î±=0.05, FANTOM-1) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | # genes/isoforms | Queued | Executed | Last 10 days | | 87554 | 61490 | 59986 (68.51%) | 88.80/day | +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

This indicates there are (87554 - 59986) / 88.80 = 310.45 days remaining which gives February 7th, 2023 as the estimated completion date at the current rate.
