The owner of Meta wants more "masculine energy"? Well, I'm doing my best to bring my feminine energy to the Fediverse. <br /> <br /> Hello! I'm Elena Rossini, an Italian filmmaker, photographer and FOSS advocate based in Paris, France. <br /> <br /> Pictured here: at the Louvre museum after a portrait shoot (for a book jacket's author's pic: Monica Parker, The Power of Wonder). I'm proudly wearing around my neck my 3 cameras: a <a href="https://photos.elenarossini.com/discover/tags/Canon?src=hash" title="#Canon" class="u-url hashtag" rel="external nofollow noopener">#Canon</a> 5D Mark IV, a <a href="https://photos.elenarossini.com/discover/tags/Fujifilm?src=hash" title="#Fujifilm" class="u-url hashtag" rel="external nofollow noopener">#Fujifilm</a> X-T3 and a <a href="https://photos.elenarossini.com/discover/tags/Nikon?src=hash" title="#Nikon" class="u-url hashtag" rel="external nofollow noopener">#Nikon</a> Z fc (which has my favorite lens, a Sigma 30mm f/1.4).<br /> <br /> I'm delighted to see Pixelfed growing into such a nice photo community.

<p>Just learned about this recent case where a transgender person in Karnataka, India successfully challenged the Registrar to accommodate name and gender changes (not possible by prior law). Progress that I couldn&#39;t have imagined decades ago.<br /><a href="https://clpr.org.in/litigation/ms-x-v-state-of-karnataka/" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="ellipsis">clpr.org.in/litigation/ms-x-v-</span><span class="invisible">state-of-karnataka/</span></a></p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@regehr" class="u-url mention">@<span>regehr</span></a></span> actually it&#39;s interesting to me that you say it doesn&#39;t matter in practice, do you know why? also, can you explain how quantifier elimination works?</p>
