Ocean acidification due to carbon emissions is at highest for 300 million years
the oceans have now reached a level of acidity that has not been reached in the past 300 million years. This is due to carbon dioxide emissions from burning fossil fuels. Carbon dioxide in the atmosphere is absorbed by the ocean, and it is estimated that at least a third of what humans have emitted has been absorbed already. this will lead to mass extinction of key species in the ocean ecosystem, and is at this point a certainty. Alex Rogers, professor of biology at Oxford University, has said: "The health of the ocean is spiralling downwards far more rapidly than we had thought."

v 0.10.0.0
name nation_genesis
description 0.10.0 (nation_genesis): - added first version of a user system (gf_identity) - adding first version of p2p system based on libp2p - initial version of gf_home, personal control panel for users - gf_admin added, for admin login and control of a particular GF server/node 0.9.0 (solo_learner): - new gf_solo service has been introduced, that compiles all other services into a single binary. - first additions of ML functionality. Addition of Rust code for collage composition and efficient building of .tfrecords from images. addition of basic ML models in Py. - various improvements to gf_core, around error handling, etc. improvements to gf_rpc_lib. 0.8.0 (precious): - OPEN_SOURCING!! GF has been open sourced. gf_publisher, gf_landing_page, gf_tagger have also been refactored to use the new error handling structure, thats in place for gf_images and gf_analytics (gf_crawl_lib). 0.7.4: - first prototype of the most basic image_editor (image filters/cropping) added. Still needs polish and integration of the UI into the rest of the system. 0.7.3.1: - big refactor of how statistics are structured in all services, to standardize on gf_stats accross the whole system. all stats are now accessible via gf_analytics only, not in custom dashboards of each of the services themselves (this way expensive stats calculations are only run in the gf_analytics service machines, not on machines of other services that are expected to efficiently handle real-time requests). 0.7.3: - big refactor of error handling, a system wide gf_error code is now used. not all packages migrated yet, but core ones (gf_images,gf_crawl_lib,gf_analytics) are. 0.7.2: - small improvements in adding crawled_images to flows in the crawler dashboard. 0.7.1: - gf_crawl can move images discovered in HTML pages into image flows. This is done via UI's in the crawler dashboard at the moment. 0.7.0 (sparkly): - first round of GIF viewer/posting features. GIF's are now clickable/playable in the flows_browser, and can be added via the gf_chrome_ext. 0.6.0 (robust): - migrated system to multi-node cluster, separating key services to their own nodes. new cloud provider (GCP). 0.5.0 (raise): - addition of the "gf_crawl" application, which crawls the image-web for images from select sites. these images are then accessible in their own crawled/discovered image flow. "gf_crawl" functionality is working as a part of the gf_analytics service for now. 0.4.4: - addition of the "gf_domains" application. UI for it is publicly accessible, which for now gives basic stats an all domains discovered in lings in the GF DB. 0.4.3: - addition of the "flows" functionality to the "gf_images" application. 0.4.0: - rewrite of the entire backend in Golang, and the front-end in Typescript. major effort, and took over a year (if not longer) to complete, due to real-life coming in the way and tech experimentation happening. 0.2: - rewrote all services and most of the front-end in Dart, very few minor improvements added. 0.1: - initial Python backend and gf_image/gf_post data-model, using mongodb, most basic css styling. first introduction of a Chrome browser extension, for creating posts only (by adding images to them), no image flows.
