A collaborative social publishing engine. Known allows any number of users to post to a shared site with blog posts, status updates, photographs, and more. Its robust open source framework can be used to build fully-fledged community sites, or a blog for a single user.

This post, referenced during our conversation today, references the case of Gab and raises the issue of whether the decentralized web is a haven for objectionable content. It's also a good example of a website using WebMentions to link to comments made on other website (including, of everything works, this one).

This is a long (136 page PDF) and detailed report on blockchains in education. The authors work slowly and deliberately in their pursuit of accuracy and clarity, which results in a presentation that will be easily understood by most readers. There is a wealth of examples in the document describing use cases, scenarios and pilot projects, and companies involved in the space.

This podcast transcript provides a level-headed overview of blockchain technologies focusing especially on the trade-offs the use of blockchain entails (for example: less efficient databases in exchange for immutability). There's also a nice table depicting the major use cases for blockchain. And there's a nice look at the different motivations for employing blockchain.

This is a good crisp summary that doesn't shy away from technical detail but steps through the major elements of blockchain technology with clarity and precision. The sections on blockchain components (section 3) and consensus models (section 4) are particularly strong. It even comes with a fun blockchain use case flowchart.

You may have heard of GitHub - the open source software repository that was recently acquired by Microsoft for $7.5 billion. GitHub is important because it allows authors to release related versions of their software, to incorporate and merge contributions from many authors, and to allow people to create their own version (or 'fork') any application. To do this, GitHub is structured as a Directed Acyclic Graph, creating a series of relationships among code libraries.

Graphs are important types of data structures. Instead of thinking of things in rows and columns (the way we would in a spreadsheet or a database) we think of things as nodes and edges. This page has a very brief description of a graph data structure and then a long list of things that can be done with graphs - cycling, sortinfg, spanning, searching. This page is meant to explor, not to learn - ollow the links, try running some of the code (click on the r'run in IDE button').

The diagram in this resource descibes some different types of neural networks. Take a look at the specific tasks they perform - neural networks are good at things like classification and recgnition, as well as regression (that is, finding a trend or regulrity in data). I got this image from this page, which has more resourcs on neural networks.

Neural Networks are types of graphs. In the past I have stated that in order to be a network, a change of state in one entity in a graph must be capable of producing a change of state in another entity. Neural networks are therefore dynamic and interactive graphs. This resource describes a bunch of different neural networks. Different neural networks have different capabilities, and today are playing an increasingly important role in artificial intelligence.

This is a gentle introduction to graph theory. Graphs are data structires in which entities - called 'nodes' - are connected to other entitis via some sort of a link - called an 'edge'. In graph theory there are no limits on what can be connected, nor how they can be connected. Defining graphs in specific ways, however, creates the structures that underlie most of the modern web.

This week in the #EL30 course with Stephen Downes, we are looking at graphs. First, two passages from his recent draft monograph on graphs. “In connectivism we have explored the idea of thinking of knowledge as a graph, and of learning as the growth and manipulation of a graph. It helps learners understand that each […] Web: [Direct Link] [This Post]

It bugs me when some peer nerds urge all the rest of the world to adopt our way of thinking. Probably they are confusing two important things.

Graph is the Topic for Week 3 of Stephen Downes’ E-Learning 3.0 MOOC. Again, he has provided a good Synopsis – see https://el30.mooc.ca/cgi-bin/page.cgi?module=7. In the last three paragraphs in this synopsis he writes: In connectivism we have explored the idea… Continue reading → Web: [Direct Link] [This Post]

Week 3 of Stephen Downes’ E-Learning 3.0 course is looking at Graphs. Stephen recommended some resources for this topic. These included: Vaidehi Joshi’s (2017) gentle introduction to graph theory. In her discussion of graphs, Vaidehi observes “in mathematics, graphs are a way to formally represent a network, which is basically just a collection of objects … Continue reading #EL30 Graphing Web: [Direct Link] [This Post]

This is an important article by Ton Zijlstra about “distributed technology” and the long tail. In fact, he applies it to Mastodon, a decentralized combination of microblogging and virtual communities. I quote: This is the notion that tool usage having a long tail is a measure of distribution, and as such a proxy for networked […] Web: [Direct Link] [This Post]

Stephen has tasked us all with creating a graph of some sort for #el30 this week. Questions that came into my mind were: What are the parameters? How do they interact? How can I make visible the potentials? I’m thinking of learning and what’s visible, what we bring, resources, and what is ideal to implement […] The post Graph #el30 Week 3 appeared first on lauraritchie.com.

The task for this week in the course E-learning 3.0: Create a model graph of some aspect of the E-Learning 3.0 course (it doesn’t have to be an actual graph, only a representation of what an actual graph might look like. We’ve already seen, eg., graphs on the relations between people in the course. Could […] Web: [Direct Link] [This Post]

Facilitator Stephen Downes of the course E-learning 3.0 (#el30) explains Graphs in this video. In his own words: The graph is the conceptual basis for web3 networks.

Trees start from a root node and might connect to other nodes, which means that could contain subtrees within them. Trees are defined by a certain set of rules: one root node may or may not connect to others, but ultimately, it all stems from one specific place. The tree follows one direction and cannot […] Web: [Direct Link] [This Post]

Found via Twitter, definitely worth a look: "The graph is directed. The graph's vertices were grouped by cluster using the Clauset-Newman-Moore cluster algorithm. The graph was laid out using the Grid layout algorithm."

Attempt at witty title probably failed :-) I guess I am a little rusty  with creating meaningful blog titles since I have not been blogging frequently recently.  Oh well. I will get back into the swing of things once I finish my EdD...or not... ;-) In any case, I am catching up with #el30, more specifically last week's guest Ben Werdmuller (see recording here). Interesting fun fact - Ben is the creator of Elgg, which is the platform that Athabasca University's "Landing" runs on. There were quite a few interesting things that came out of the conversation but there were two that really stuck out to me.

The graph refers to the formal properties network and the network to the physical properties of the graph. The beginning of the Web: It started out as a decentralized network of interconnected servers, overtime it became dominated by platforms like google. The original web was hard to use. They needed an index, bookmarks etc. The people […] Web: [Direct Link] [This Post]
