Two RSS feeds not updating

gwene.com.phoronix - http://www.phoronix.com/rss.php
gwene.org.acm.cacm.magazine - https://cacm.acm.org/magazine.rss

These feed links work, but Gwene doesn't show new posts. Have they
blocked Gwene, or is something else wrong?

Note that the CACM link blocks Wget unless its User-Agent is
changed.
