Hi

My name is Zhenkai and this is where I host my Obsidian notes and occasional blog posts. Have fun browsing! Feel free to say hi on Discord: @tinkerrc. You can also download my GPG key here.

Don’t know what to look for? Check out some maps of content below.

• Cyber Security
• OSCP
• Red Team Ops I
• Active Directory
• Binary Exploitation
• AWS

Want to wander around? Use tags to look for notes and use the Backlinks section to navigate. You can also use #<tag> in search bar.

• blog: Blog posts.
• writeup: HTB/CTF challenge writeups.
• ttp: TTPs, which are red teaming / pentesting-oriented notes.
• course: These are some of the courses I’ve taken, and often you can find my lecture notes in the Backlinks section.
• moc: Maps of content, which are indices of large topics.
• concept: Concepts.
• how-to: How-to’s / guides.
• daily: Daily notes, which usually contain lecture notes.
• literature: These are literature notes which contains metadata and sometimes exported annotations or notes. This website does not provide any PDF files for download, but the note might contain a URL to the source if it’s publicly available.
• stub: These are empty notes that exist for linking purposes. My goal is to reduce them over time by integrating information from backlinks into the note itself.

Why are my note titles all in lowercase?

Since Zettelkasten encourages link-making, I find that lowercase note titles make inline links look more natural, e.g., A [[function]] is a mapping from [[domain]] to [[codomain]] looks better than A [[Function]] is a mapping from [[Domain]] to [[Codomain]] or A [[Function|function]] is a mapping from [[Domain|domain]] to [[Codomain|codomain]]. Although Obsidian wikilinks are now case-insensitive, it is nonetheless more productive when a link autocompletes to lowercase, which is what I want most of the time, and I can manually fix the cases where I need to capitalize a link at the start of sentence. I still keep proper nouns in their original case though. See also Zettelkasten workflow for how I take notes.

Website Roadmap

• Hide the tags row on home page.
• Display source metadata (see ContentMeta.tsx).
• Put the dark mode toggle next to the search bar.
• Display created / updated metadata.
• Convert note timestamps to the right timezone.
• Remove unneeded tags.
• Display related metadata. Include mentioned pages in backlinks.
• Display source links in graph.
• Scrollable right sidebar.
• Replicate Supercharged Links plugin on the website.
• Proper tag description pages (for major tags).
• Add a custom favicon.
