Editorial pass & migration to mkdocs.
There's a lot in grimoire.ca that I either no longer stand behind or feel pretty weird about having out there.

Who Needs Those?<a class="headerlink" href="#protected-feeds-who-needs-those" title="Permanent link">¶</a></h2> +<p>Gossamer's design does not carry forward an important Twitter feature: the +protected feed. In brief, protected feeds allow people to be choosy about who +reads their status updates, without necessarily having to pick and choose who +gets to read them on a message by message basis.</p> +<p>This is an important privacy control for people who wish to engage with +people they know without necessarily disclosing their whereabouts and +activities to the world at large. In particular, it's important to vulnerable +people because it allows them to create their own safe spaces.</p> +<p>Protected feeds are not mere technology, either. Protected feeds carry with +them social expectations: Twitter clients often either refuse to copy text +from a protected feed, or present a warning when the user tries to copy text, +which acts as a very cheap and, apparently, quite effective brake on the +casual re-sharing that Twitter encourages for public feeds.</p> +<h2 id="ddos-as-a-service">DDOS As A Service<a class="headerlink" href="#ddos-as-a-service" title="Permanent link">¶</a></h2> +<p>Gossamer's network protocol converges towards a total graph, where every node +knows how to connect to every other node, and new information (new posts) +rapidly push out to every single node.</p> +<p>If you've ever been privy to the Twitter “firehose” feed, you'll understand +why this is a drastic mistake. Even a moderately successful social network +sees on the order of millions of messages a day. Delivering <em>all</em> of this +directly to <em>every</em> node <em>all</em> of the time would rapidly drown users in +bandwidth charges and render their internet connections completely unusable.</p> +<p>Gossamer's design also has no concept of “quiet” periods: every fifteen to +thirty seconds, rain or shine, every node is supposed to wake up and exchange +data with some other node, regardless of how long it's been since either node +in the exchange has seen new data. This very effectively ensures that +Gossamer will continue to flood nodes with traffic at all times; the only way +to halt the flood is to shut off the Gossamer client.</p> +<h2 id="passive-nodes-matter">Passive Nodes Matter<a class="headerlink" href="#passive-nodes-matter" title="Permanent link">¶</a></h2> +<p>It's impractical to run an inbound data service on a mobile device. Mobile +devices are, by and large, not addressable or reachable by the internet at +large.</p> +<p>Mobile devices also provide a huge proportion of Twitter's content: the +ability to rapidly post photos, location tags, and short text while away from +desks, laptops, and formal internet connections is a huge boon for ad-hoc +social organization. You can invite someone to the pub from your phone, from +in front of the pub.</p> +<p>(This interacts ... poorly with the DDOS point, above.)</p> +<h2 id="traffic-analysis">Traffic Analysis<a class="headerlink" href="#traffic-analysis" title="Permanent link">¶</a></h2> +<p>When a user enters a new status update or sends a new private message, their +Gossamer node immediately forwards it to at least one other node to inject it +into the network. This makes unencrypted Gossamer relatively vulnerable to +traffic analysis for correlating Gossamer identities with human beings.</p> +<p>Someone at a network “pinch point” -- an ISP, or a coffee shop wifi router -- +can monitor Gossamer traffic entering and exiting nodes on their network and +easily identify which nodes originated which messages, and thus which nodes +have access to which identities. This seriously compromises the effectiveness +of Gossamer's decentralized, self-certifying identities.</p></div> + </div> + + <footer class="col-md-12"> + <hr> + <p>Documentation built with <a href="https://www.mkdocs.org/">MkDocs</a>.</p> + </footer> + <script> + var base_url = "../..", + shortcuts = {"help": 191, "next": 78, "previous": 80, "search": 83}; + </script> + <script src="../../js/base.js" defer></script> + <script src="../../search/main.js" defer></script> + + <div class="modal" id="mkdocs_search_modal" tabindex="-1" role="dialog" aria-labelledby="Search Modal" aria-hidden="true"> + <div class="modal-dialog"> + <div class="modal-content"> + <div class="modal-header"> + <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button> + <h4 class="modal-title" id="exampleModalLabel">Search</h4> + </div> + <div class="modal-body"> + <p> + From here you can search these documents.
