<li>Alliance’s TIP team emailed me to ask about issues authenticating on CGSpace
<ul>
<li>It seems their password expired, which is annoying</li>
</ul>
</li>
<li>I continued looking at the CGSpace subjects for the FAO / AGROVOC exercise that I started last week
<ul>
<li>There are many of our subjects that would match if they added a “-” like “high yielding varieties” or used singular…</li>
<li>Also I found at least two spelling mistakes, for example “decison support systems”, which would match if it was spelled correctly</li>
</ul>
</li>
<li>Work on cleaning, proofing, and uploading twenty-seven records for IFPRI to CGSpace</li>
</ul>
<ul>
<li>I notice there are a few dozen locks from the <code>dspaceWeb</code> pool that are five days old on CGSpace so I killed them</li>
<li>I replaced one item’s thumbnail with a WebP version and XMLUI displays it fine</li>
<li>I spent some time checking the CMYK issue with Arch’s ImageMagick 7 and the Docker container and I think ImageMagick 7 just handles CMYK wrong…
<ul>
<li>libvips does it correctly automatically and looks closer to the PDF</li>

<li>I finally cleaned up and published my latest evaluation of <ahref="https://alanorth.github.io/improved-dspace-thumbnails/evaluating-jpeg-webp-avif.html">JPEG, WebP, and AVIF</a>
<ul>
<li>I <ahref="https://github.com/DSpace/DSpace/issues/8849">filed an issue on DSpace</a> to track this</li>
</ul>

<ul>
<li>Re-sync CGSpace to DSpace 7 Test</li>
<li>I came up with a naive patch to use WebP instead of JPEG in the DSpace ImageMagick filter, and it works, but doesn’t replace existing JPEGs… hmmm
<ul>
<li>Also, it does PDF to WebP to WebP haha</li>
</ul>
</li>

<h2id="2023-05-18">2023-05-18</h2>
<ul>
<li>I created a <ahref="https://github.com/DSpace/DSpace/pull/8850">pull request</a> to improve some minor documentation, typo, and logic issues in the DSpace ImageMagick thumbnail filters</li>
<li>I realized that there is a quick win to the generation loss issue with ImageMagickThumbnailFilter
<ul>
<li>We can use ImageMagick’s internal MIFF instead of JPEG when writing the intermediate image</li>
<li>According to the <ahref="https://github.com/libvips/libvips/issues/571">libvips author PNG is very slow</a>!</li>
<li>I re-ran my <code>generation-loss.sh</code> script using MIFF and found that it had essentially the same results as PNG, which is about 1.1 points higher on the ssimulacra2 (v2.1) scoring scale</li>
<li>Also, according to my tests with the cosmo rusage.com utility, I see that MIFF is indeed much faster than PNG</li>
<li>I updated my pull request to add this quick win</li>

<li>Weekly CG Core types meeting

<li>Low attendance so I just kept working on the spreadsheet</li>
<li>We are at the stage of voting on definitions</li>
