Wireshark capture filter Updated 2025-07-16
Capture by instead:
sudo wireshark -f http -k
sudo wireshark -f icmp -kFilter by both protocol and host:
sudo wireshark -f 'host 192.168.1.102 and icmp' -kFor application layer capture filtering, the best you can do is by port:There is an
sudo wireshark -f 'tcp port 80'http filter but only for as a wireshark display filter Universal Scene Description Updated 2025-07-16

List of personal knowledge base software Updated 2025-07-19
Lists:
- www.bibsonomy.org/user/bshanks/education fantastic list, presumably by this guy:
- www.reddit.com/r/Zettelkasten/comments/168cmca/which_note_taking_app_for_a_luhmann_zettlekasten/
- www.reddit.com/r/productivity/comments/18vvavl/best_free_notetaking_app_switching_from_evernote/
- github.com/topics/note-taking has a billion projects. Oops.
- github.com/MaggieAppleton/digital-gardeners
- www.noteapps.ca/
Personal knowledge base software recommendation threads:
TODO look into those more:
- roamresearch.com/ no public graphs
- nesslabs.com/roam-research-alternatives a bunch of open source alternatives to it
- Trillium Notes. Notable project! Pun unintended!
- Stroll giffmex.org/stroll/stroll.html. How to publish? How to see tree?
- tiddlyroam joekroese.github.io/tiddlyroam/ graph rather than text searchable ToC. Public instance? Multiuser?
- Athens github.com/athensresearch/athens rudimentary WYSIWYG
- Logseq github.com/logseq/logseq no web interface/centralized server?
- itsfoss.com/obsidian-markdown-editor. Closed source. They have an OK static website publication mechanism: publish.obsidian.md/ram-rachum-research/Public/Agents+aren't+objective+entities%2C+they're+a+model but leaf node view only for now, no cross source page render. They are committed to having plaintext source which is cool: twitter.com/kepano/status/1675626836821409792
- CherryTree github.com/giuspen/cherrytree written in C++, GTK, WYSIWYG
- github.com/dullage/flatnotes: Python
- github.com/usememos/memos: Go
- github.com/siyuan-note/siyuan: Go
- github.com/vnotex/vnote: C++
- github.com/Laverna/laverna: JavaScript
- github.com/taniarascia/takenote
- github.com/silverbulletmd/silverbullet: TypeScript, Markdown, web-based WYSIWYG, focus on querying
Major downsides that most of those personal knowledge databases have:
- very little/no focus on public publishing, which is the primary focus of OurBigBook.com
- either limited or no multiuser features, e.g. edit protection and cross user topics
- graph based instead of tree based. For books we need a single clear ordering of a tree. Graph should come as a secondary thing through tags.

Quantum computer simulator Updated 2025-07-16
Other good lists:
- quantumcomputingreport.com/resources/tools/ is hard to beat as usual.
- www.quantiki.org/wiki/list-qc-simulators
- JavaScript
- algassert.com/quirk demo: github.com/Strilanc/Quirk drag-and-drop, by a 2019-quantum-computing-Googler, impressive. You can create gates. State store in URL.
- github.com/stewdio/q.js/ demo: quantumjavascript.app/
Bibliography:
- www.epcc.ed.ac.uk/whats-happening/articles/energy-efficient-quantum-computing-simulations mentions two types of quantum computer simulation:
The most common approach to quantum simulations is to store the whole state in memory and to modify it with gates in a given order
However, there is a completely different approach that can sometimes eliminate this issue - tensor networks
