Encyclopedia of American Activism 1960 to the Present by Margaret DiCanio, 2016

The turbulence of the 1960s and 1970s spawned a spectrum of activist movements. In spirit and action, events ranged from: gentle to violent; from Tree People to Bloody Sunday; from Community Mental Health to Black Power. This rapid stream of social and political change defined the second half of the 20th century, yet had roots in the first half.

While I am just feeding no-other-obvious-source lisp pieces of my brain to my young kitten, here is principle component analysis in common lisp using an openly available #ML package #clml from a Japanese telco changing hands 15 years ago, actively developed by a lisp lone wolf up until five years ago.

My demo is in english (#emacs #eev #eepitch) in contrast to the Japanese internals.

I just whipped up a simple icon search for Kitten Icons (based on Phosphor Icons). It’s not complete yet – I have a few other things to do before I can get back to it today – but you can play with it here:

And see the code for it here:

I popped the event handler into the Markdown page itself. Not the cleanest but works in a pinch:

Spotted on Mastodon: a spreadsheet of 900 media outlets with a Fediverse presence. “I did it! Although it’s still very rough & really not pretty, I got my spreadsheet with (> 900) verified accounts of media organizations in the #Fediverse away from #Google. The solution was #DataTables all along.”

Happy to announce a new paper of my 0hd student Paula Gauvin:
An annotated reference library for supporting DNA metabarcoding analysis of aquatic macroinvertebrates in French freshwater environments

Metabarcoding and MetagenomicsAn annotated reference library for supporting DNA metabarcoding analysis of aquatic macroinvertebrates in French freshwater environmentsFreshwater ecosystems are increasingly threatened by human activities, leading to biodiversity loss and ecosystem degradation. Effective biodiversity monitoring, particularly through the use of aquatic macroinvertebrates as bioindicators, is crucial for assessing ecological health. While traditional morphological methods face limitations, DNA metabarcoding offers higher accuracy and efficiency in species identification using environmental DNA. However, the success of metabarcoding is contingent on the quality of reference libraries, which are often incomplete or biased. This study aimed to construct and share a comprehensive COI-based DNA barcode library for freshwater macroinvertebrates in France, specifically targeting short gene regions amplified with fwhF2/fwhR2N primers, suitable for degraded DNA. A list of species occurring in French freshwater ecosystems was established from official national checklists and Alpine lake surveys. The resulting library was analysed for taxonomic completeness, barcode coverage and cryptic diversity. The checklist consisted of 2,841 species across 10 phyla, for which 56% had at least one COI-5P sequence available in the Barcode of Life Data System (BOLD). The analysis of cryptic diversity, based on Barcode Index Numbers (BINs) highlighted a potential high rate of cryptic diversity, although it might have been overestimated due to the wide geographic origin of the sequences. Alignment challenges with the primers were identified for certain taxa, particularly amongst Coleoptera, Diptera and Malacostraca. The genetic diversity approached by the number of haplotypes per species highlighted that most of the species have limited diversity, with only three species having more than 100 haplotypes. Finally, this study showed that a total of 57 haplotypes were shared amongst 116 distinct species. This work emphasises the need for expanded sequencing efforts to improve barcode coverage and highlighted the pitfalls associated with the use of these primers for further biodiversity assessment of macroinvertebrates with DNA.
