Nate<p>I was planning on attending <a href="https://tech.lgbt/tags/defcon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>defcon</span></a> this year, until I saw the price. How is the cost justified? What am I getting for almost $600? That pricing is wildly outside of my con expectations.</p>

MissConstrue<p>So, <a href="https://mefi.social/tags/RSAC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RSAC</span></a> is happening right now. For those outside <a href="https://mefi.social/tags/infosec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>infosec</span></a>, you’ve probably never heard of it, despite its 30+ year history. If you can imagine <a href="https://mefi.social/tags/Defcon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Defcon</span></a> put on by LinkedIn, that’s pretty much RSAC. Wall to wall feds and salesmen, with some really cool panels. </p><p>Except this year, they pulled a fast one, cancelled the most anticipated panel, ( NSA's State of the Hack 2025 ) and added DOJ Barbie Kristi Noem as the keynote speaker. This after RSAC and most of corporate IT has turned their back on Chris Krebs who led CISA. </p><p>Disgraceful. </p><p><a href="https://www.theregister.com/2025/04/30/noem_put_cisa_on_mission/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">theregister.com/2025/04/30/noe</span><span class="invisible">m_put_cisa_on_mission/</span></a></p>

support@defcon.social<p>We are in the midst of getting ready to migrate our MinIO servers to larger disks 30TB -&gt; 60TB to address unexpectedly running critically low on space.
