using pngquant and OptiPNG. Result:
arresteddevops-tn.png 154734 bytes → 47184 bytes
maximeguitare-tn.png 95571 bytes → 24183 bytes

And a small one to an even smaller one too:

Some of the thumbnails in Showcase were out of place
because of several irregularly sized thumbnails,
and some of them almost 300KB in filesize.
Resize them all to 600x400 (pixels), and use the `-tn.png`
suffix.
When necessary, the website snapshot is re-captured using
gnome-web-photo. Then, the following commands (or a combination
thereof) are used to crop and resize the image into a thumbnail,
and to reduce its filesize:
$ convert example.png -crop 900x600+0+0 \
-filter Lanczos2Sharp -distort Resize 600x400 \
example-tn.png
$ pngquant --nofs -v --speed 1 --quality 65-80 example-tn.png
$ optipng -o7 -zm1-9 example-tn-or8.png
$ mv example-tn-or8.png example-tn.png
Found on @spf13's Twitter. :-)
Prevent the testimonial dates from wrapping.
Also fix a few minor problems to get the home page
to validate as proper HTML5.
Extracted from https://www.freebsd.org/logo/logo-simple.svg
for temporary use until a future Font Awesome release adds
the `fa-freebsd` glyph (github/FortAwesome/Font-Awesome#1116) :-)
Make .fa `display: inline` to prevent unwanted line-wrapping
Also make the menu item "Issue & Help" line up with the others.
Hopefully making them more semantic and easier to read,
though it is raw HTML so it is slightly more work to maintain.
Also made minor revisions to some of the variable descriptions
to be more informative, e.g. `:monthname` in permalinks use
full English names ("January" etc.)
Make the sidebar menu slightly wider so the arrow
does not get pushed to the next line.
Also remove `text-transform: capitalize;` so we can have,
e.g., "Table of Contents" rather than "Table Of Contents".
