This Week I Learned - Week #24 2025

This Week I Learned - 

* Reddit, “the front page of the internet” has turned 20 -  It is one of the last outposts for that old internet – hobbyist, collaborative, more than a little eccentric. Almost 100 million people actively use the site every day

* Google Brain invented the transformer network and OpenAI scaled it up

* Archive.today takes a 'snapshot' of a webpage that will always be online even if the original page disappears. It saves a text and a graphical copy of the page for better accuracy and provides a short and reliable link to an unalterable record of any web page including those from Web 2.0 sites.

* Nvidia has unveiled a new generative foundation model that it says enables simulations of Earth’s global climate with an unprecedented level of resolution. The model, branded by Nvidia as cBottle for "Climate in a Bottle," compresses the scale of Earth observation data 3,000 times and transforms it into ultra-high-resolution, queryable and interactive climate simulations. It was trained on high-resolution physical climate simulations and estimates of observed atmospheric states over the past 50 years. The cost of running a high-resolution weather simulation every hour for a full year is $3 million if you do it the traditional way, on CPUs, according to Nvidia. The company said its CorrDiff generative AI model running on its GPUs can perform that task for $60,000. The new models still don’t provide 100% certainty. They don’t state that the weather or climate will be one thing or another, but rather provide probabilities for certain outcomes. 

* Starlink plans to deliver 600–700 Gbps of bandwidth through its low-Earth orbit (LEO) satellite constellation, targeting rural and remote areas where conventional fibre and mobile networks remain limited or unreliable in India. Starlink currently operates across select Asian countries, including Japan, Malaysia, Indonesia, the Philippines, Bhutan, and Bangladesh.

* There are some 35.4 million people of Indian origin, PIOs, scattered across the globe.

* English pronunciation for Hindi speakers on Google can help with words that have quirky pronunciations -

* How to stay centered when the world feels chaotic - Practice being present in the here and now. It’s all we have, and it’s a lot
