< li > I noticed a URL for this < a href = "https://hdl.handle.net/10568/89049" > Bioversity item< / a > redirects incorrectly

< / li >
< li > The < code > dspace cleanup -v< / code > finally finished after a few days of running and stopping… < / li >
< li > I decided to update the thumbnails in the Bioversity books collection because I saw a few old ones suffering from the CropBox issue< / li >
< li > Also, all day there’ s been a high load on CGSpace, with lots of locks in PostgreSQL
< ul >
< li > I had been waiting until the bitstream cleanup finished… now I might need to restart PostgreSQL to kill some old locks as something needs to give< / li >

< li > As the quality settings are not comparable between formats, we need to compare the formats at matching perceptual scores (ssimulacra2 in this case)< / li >
< li > I used a ssimulacra2 score of 80 because that’ s the about the highest score I see with WebP using my samples, though JPEG and AVIF do go higher< / li >
< li > Also, according to current ssimulacra2 (v2.1), a score of 70 is “ high quality” and a score of 90 is “ very high quality” , so 80 should be reasonably high enough… < / li >
