Felix Palmen :freebsd: :c64:<p>Still working on <a href="https://mastodon.bsd.cafe/tags/swad" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>swad</span></a>, and currently very busy with improving quality, most of the actual work done inside my <a href="https://mastodon.bsd.cafe/tags/poser" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>poser</span></a> library.</p><p>After finally supporting <a href="https://mastodon.bsd.cafe/tags/kqueue" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>kqueue</span></a> and <a href="https://mastodon.bsd.cafe/tags/epoll" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>epoll</span></a>, I now integrated <a href="https://mastodon.bsd.cafe/tags/xxhash" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>xxhash</span></a> to completely replace my previous stupid and naive hashing. I also added a more involved <a href="https://mastodon.bsd.cafe/tags/dictionary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dictionary</span></a> class as an alternative to the already existing <a href="https://mastodon.bsd.cafe/tags/hashtable" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hashtable</span></a>. While the hashtable's size must be pre-configured and collissions are only ever resolved by storing linked lists, the new dictionary dynamically nests multiple hashtables (using different bits of a single hash value). I hope to achieve acceptable scaling while maintaining also acceptable memory overhead that way ...</p><p><a href="https://mastodon.bsd.cafe/tags/swad" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>swad</span></a> already uses both container classes as appropriate.</p><p>Next I'll probably revisit poser's <a href="https://mastodon.bsd.cafe/tags/threadpool" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>threadpool</span></a>. I think I could replace <a href="https://mastodon.bsd.cafe/tags/pthread" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pthread</span></a> condition variables by "simple" <a href="https://mastodon.bsd.cafe/tags/semaphores" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>semaphores</span></a>, which should also reduce overhead ... </p><p><a href="https://github.com/Zirias/swad" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/Zirias/swad</span><span class="invisible"></span></a></p><p><a href="https://mastodon.bsd.cafe/tags/c" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>c</span></a> <a href="https://mastodon.bsd.cafe/tags/coding" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coding</span></a></p>
Stéphane Charette 🇨🇦<p>Now that I'm several days into removing pthread from Darknet/YOLO I can finally comment on the image data loading process.</p><p>Both how it is currently implemented, and what I'm doing to change it.</p><p>A short thread into one of the "darker" portions of the Darknet/YOLO codebase...</p><p><a href="https://mstdn.ca/tags/darknet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>darknet</span></a> <a href="https://mstdn.ca/tags/yolo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>yolo</span></a> <a href="https://mstdn.ca/tags/cpp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpp</span></a> <a href="https://mstdn.ca/tags/pthread" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pthread</span></a></p><p>🧵 1/8</p>
