This was on Void Processes, a mechanism to statically distribute fine-grained privilege to application processes on Linux.
My dissertation is available here. I plan to make a series of posts over the next few weeks documenting my findings in smaller snippets, particularly the experience of voiding mount namespaces. In the future, I hope to produce some work which increases the performance of creating empty namespaces....</p></section><footerclass=entry-footer><spantitle='2022-06-06 14:00:00 +0100 +0100'>June 6, 2022</span> · 2 min · Jake Hillion</footer><aclass=entry-linkaria-label="post link to Void Processes: Minimising privilege by default"href=https://blog.hillion.co.uk/posts/void-processes/dissertation/></a></article><articleclass=post-entry><headerclass=entry-header><h2>Chia Database Torrents 🌱👨💻🌐</h2></header><sectionclass=entry-content><p>Having trouble keeping your Chia database in sync? Database corruption leading to days or weeks of syncing? These Chia database torrents might help you out.
I had the same problem myself, and tried to backup the database file like I would most things.
