<h2>Curriculum Vitae</h2>

</div>
<h2>Projects</h2>
<ul>
<li>I wrote a <a href=>YAML Parser in VBA</a> to generate my CV from a YAML source, and updated the <a href=>VBASync</a> C# application, which detaches VBA from its associated document for version control, so that it could be compiled on modern systems.</li>
<li>Wrote a <a href="https://sprightly-malabi-9b60b5.netlify.app/booktracker/all/">book tracker</a> in node.js, which pulled together the SQLite databases of <a href=https://www.orgroam.com/>org-roam</a> and <a href=https://www.zotero.org/>Zotero</a> and generated a static "app" which showed progress and notes. I am not actively using it to track readings anymore, although it might be revived someday. Neither Zotero or org-roam document their schemas well, so I had to reverse-engineer them!</li>
<li>Wrote a combination <a href=https://git.bql.7800.io/old_projects/url_shortener.git/tree>URL shortener and pastebin</a> in Rust + tokio which included its own <i>very</i> basic templating engine.
<li>Wrote a <a href=https://git.bql.7800.io/old_projects/demo_old.git/tree>basic wireframe 3D renderer</a> in Java, which includes a linalg library.</li>
</ul>
<h2>Homelab</h2>
I currently run a homelab with the following specs, which hosts various selfhosted services at <a href=https://bql.7800.io>bql.7800.io</a>.

You may notice that the kernel version is quite out-of-date. This is because the SoC that my server uses (the <a href=https://www.hisilicon.com/en/products/kirin/kirin-flagship-chips/kirin-9000>Kirin 9000c</a>) does not have kernel source available for it.
In order to run an unsupported distribution, I had to debug anomalous behaviour at the kernel level, gained insight into how Huawei used proprietary <a href=https://en.wikipedia.org/wiki/Linux_Security_Modules>linux security modules</a> for security on their enterprise offerings, and communicated with kernel devs in Mandarin to obtain a custom-compiled kernel that did not contain Huawei's security features. Hopefully, I'll write a blog post about this in the future.
