Why we've changed our database schema 26 times until now:
- make Coocook easier to use by simplifying required input
- add new features like organizations (groups of users)
- add missing metadata like creation timestamps

Longer gaps are difficult changes that took long to prepare:
1. add database versioning in the first place
2. drop infamous table "quantities" that connected units that can be converted, like "masses" with lb and kg, etc.🙈

In a #nutshell, what you're #locking is your #dependency #graph. i.e. your project says you need the `requests` package v.1.2.3 or later, plus the `pandas` package version 2 (not 3, you haven't upgraded your code yet).

Those each drag in a bunch of other dependencies, each with their own #version #requirements. One of them might say "I need pandas > 2.3.4". Multiple ones might all need `requests` as well, but specify different version constraints.

The development of igraph has taken great steps forward over the past few years. It now scales to billions of edges, supports Mathematica and interactive plotting, integrates with notebooks and other libraries, and includes many new algorithms. We just put out a pre-print where we provide an overview of these advances.

While #MSExchange remains a core solution in many organizations, the use of #Exchange Web Servers (#EWS) is being replaced by #Microsoft #Graph. It is important to assess whether EWS is still being used and act if necessary.

The Exchange Product Group has published a series of blogs to help with this migration. Check out the first introductory blog here: https://techcommunity.microsoft.com/t5/exchange-team-blog/ews-exchange-web-services-to-microsoft-graph-migration-guide/ba-p/3957158

#decompwlj ➡️ It's a decomposition of positive integers. The weight is the smallest such that in the Euclidean division of a number by its weight, the remainder is the jump (first difference, gap). The quotient will be the level. So to decompose a(n), we need a(n+1) with a(n+1)>a(n) (strictly increasing sequence), the decomposition is possible if a(n+1)<3/2×a(n) and we have the unique decomposition a(n) = weight × level + jump.

We see the fundamental theorem of arithmetic and the sieve of Eratosthenes in the decomposition into weight × level + jump of natural numbers. For natural numbers, the weight is the smallest prime factor of (n-1) and the level is the largest proper divisor of (n-1). Natural numbers classified by level are the (primes + 1) and natural numbers classified by weight are the (composites +1).

For prime numbers, this decomposition led to a new classification of primes. Primes classified by weight follow Legendre conjecture and i conjecture that primes classified by level rarefy. I think this conjecture is very important for the distribution of primes.

It's easy to see and prove that lesser of twin primes (>3) have a weight of 3. So the twin primes conjecture can be rewritten: there are infinitely many primes that have a weight of 3.

I am not mathematician so i decompose sequences to promote my vision of numbers. By doing these decompositions, i apply a kind of sieve on each sequences.

Was reading some graph theory stuff earlier, and came across this Wikipedia article on Graph Reduction, which provides a low-level explanation of how Lazy Evaluation in programming works.

It's a really cool (and pretty short) read: https://en.wikipedia.org/wiki/Graph_reduction

The more I learn about topics in graph theory, the more my view of everything in the world becomes more graph-like 😂

Quite neat. I’m unsure what are the benefits over providing an image (even vectorised, eg SVG), but it’s possible.

One of the things I'll be talking about in the stream tomorrow: Understanding that https://thi.ng/rstream constructs are essentially defining a #dataflow #graph much like you'd know from a node-graph based editor (a la Blender/Houdini etc.), only obviously with the difference of actually creating such a graph programmatically rather than manually via visual editing. Personally I find this programmatic approach much more powerful, but a visual representation makes it of course much easier to debug & analyze such graph topologies, also to explain & illustrate to others how data and state changes are flowing through the app/system and/or where to attach new features/nodes or optimize/restructure the topology...

Another massive benefit: This approach makes it much easier to build features such that only the most minimal amount of work needs to be done, helping to achieve better performance...

The attached diagram was generated with #Graphviz via https://thi.ng/rstream-dot and shows the dataflow graph for the image vectorization tool mentioned in previous toots.

Full size version:
https://demo.thi.ng/umbrella/trace-bitmap/topology.html

The tool itself:
https://demo.thi.ng/umbrella/trace-bitmap/

The second image shows the minimal code required to generate the #visualization source file...

Graph visualization of the different dataflow processing nodes in the example app mentioned. The nodes on the LHS are main user controllable inputs/params, connected to reactive UI components and later stream combinators (red nodes) executing the main work of the tool (image vectorizations, geometry generation, canvas rendering, SVG/JSON exports etc.)
TypeScript source code to traverse the entire data flow graph starting from a set of "root" nodes. The result is a GraphViz DOT file which can then be visualized as shown in the previous image...

I've just released a new version of Hypergraph :ferris: 🚀 🎉 !

This library uses IndexMap to keep the insertion order of the vertices and the hyperedges in the hypergraph - the goal is to have unique IDs. It appears that IndexMap doesn't use a fast hasher (https://github.com/bluss/indexmap/issues/135) like aHash - which is used by the hashmap implementation we have in std.

By switching to aHash, we get a significant performance boost!

If you think that there is far more right-wing linked violence in the US than left-wing linked violence. You are correct.

"Over the past decade... 96 percent of incidents in which extremists killed someone were committed by people motivated by right-wing ideologies. More than three-quarters of the resulting deaths — 335 of 444 — were linked to right-wing actors."

Text and graph from article:

Text: Data released by the ADL last week shows the reality. Over the past decade (the period included in YouGov’s poll), 96 percent of incidents in which extremists killed someone were committed by people motivated by right-wing ideologies. More than three-quarters of the resulting deaths — 335 of 444 — were linked to right-wing actors.

Graph showing Extremist linked deaths from 2013 to 2022.

One circle shows "incidents" which is almost completely red (for right-wing extremist) with a very small slice of orange (Domestic Islamist extremist) and an even small slice of blue (Left-wing extremist). There is a teeny-tiny sliver of gray (other).

The other circle shows "Killings."  A little over 3/4 of the circle is red (right-wing extremists). About 1/5 of the circle is orange (Domestic Islamist extremist). There is a very small slice of blue (left-wing extremist) and sliver of gray (other).

@fediversereport I voted small f as it's unclear to me whether the social #graph (or federation graph, or for that matter defederation graph) of the fediverse stack is disjoint. Given the resistance shown by #fediverse networks to indexing, I suppose it might not even be an answerable question.

Discussing the future of #collaborative #graph thinking.

"I guess one upcoming incentive for #semanticweb tech could be archiving and note keeping. For those that encounter so much info on feeds this could provide better private and collaborative means to collect stuff: ordering, selecting, describing, developing. I am thinking of the experience of using pinterest, #tumblr, #pinboard #obsidian, etc. as kind of cross-platform extensions to feeds and online collections."

I was in particular thinking of the pinboards and are.na walls of scholars like @shannonmattern @lozross and @miriamkp, which I see as examples of a scholarly practice of using boards/hashtags to build archives of posts and links.

Open semantic data in this field would mean freeing data from the feeds in more sustainable ways, beyond public bookmarks. #reclaimyourarchive

Screenshot of a Mastodon post and reply.

First post. Denny Vrandecic: Those are very relevant observations, and this leads to the one large question the Semantic Web never answered: how does the incentive infrastructure look like? The few parts of the Semantic Web that provided a decent answer to that question were the ones that were successful: schema.org, Wikidata and the wider GLAM world, usage inside emails, inside organizations as a data integration technology.

Second post. Lukas Fuchsgruber: Very interesting debate, | guess one upcoming incentive for semantic tech could be archiving and notekeeping. Fort those that encounter info in feeds this could provide better private and collaborative means to collect stuff: ordering, selecting, describing, developing. I am thinking of the experience of using pinterest, tumblr, pinboard, obsidian, etc. as kind of cross-platform extensions to feeds and online collections.

Finally updated my revised explanation of my graph layout algorithm, based on the last reported issues https://crinkles.io/writing/digl-revisited #typescript #writing #graph

@davidshq That is what I was saying, but I've probably changed my mind already. I'm not giving up #emacs for notetaking, period. I'd love to add #markdown to my notes, if I can have a freefloating viewer updating in realtime as I edit. The #graph stuff in particular looks really helpful and cool. If #obsidian doesn't do that, or something else does it better, I'm there.
