recently got access to the BlueSky beta, and decided to poke around to see what it's all about. I will save the details of what it is and how I feel about it for a different post. However, one of the first things you do when you sign up is choose a username that exists under the bsky.app domain. I have zero interest in another name rush where everyone tries to claim the shortest username possible, so I went with aaronpk.bsky.app rather than trying to get a or apk.</div> <a href="https://aaronparecki.com/2023/03/07/3/bluesky-custom-domain">continue reading...</a> </div> </div> <div class="metaline responses-summary pad"> <span><i class="star empty icon"></i> <span class="p-pk-num-likes">1</span> like</span> <span><i class="bookmark icon"></i> <span class="p-pk-num-bookmarks">1</span> bookmark</span> <span><i class="comment outline icon"></i> <span class="p-pk-num-replies">2</span> replies</span> <span><i class="file text outline icon"></i> <span class="p-pk-num-mentions">2</span> mentions</span> </div> <div class="metaline pad"> <a href="https://aaronparecki.com/2023/03/07/3/bluesky-custom-domain" class="u-url"> <time class="dt-published" datetime="2023-03-07T07:17:12-08:00"> Tue, Mar 7, 2023 7:17am -08:00 </time> </a> <span class="syndications"> <a href="https://micro.blog/aaronpk/17492820" class="u-syndication syndication"><i class="icon-microblog"></i></a> </span> <span class="right"> #<a href="/tag/indieweb" class="p-category">indieweb</a> #<a href="/tag/bluesky" class="p-category">bluesky</a> #<a href="/tag/atproto" class="p-category">atproto</a> </span> </div> <a class="u-author" href="/"></a> <div style="clear:both;"></div> </div> </li> <li class="h-entry post-entry post-type-article post " id="post-id-95470"> <div style="" class="content-area has-name"> <div class="pad"> <div class="post-text"> <h2 class="post-title"><a href="https://aaronparecki.com/2022/12/22/10/export-current-slide-keynote" class="p-name post-title">How to create a keyboard shortcut to export the current slide in Keynote</a></h2> <div class="p-summary" style="margin: 12px 0;">Lately I've been using Apple Keynote to create graphics for using in videos and blog posts.
