Report: An emerging crisis for the giant social platforms - toxic and polarised online environments, but enormous potential to transform our world in positive ways.

This is the 100 year anniversary of humans having an idea of what the heck the sun and all the stars actually are. If you had asked a leading astronomer in 1925 what the sun was, they would say that it's basically the same as Earth, but very hot.
In Cecilia Payne's doctoral thesis she was the first to say, from spectral data, that the sun was overwhelmingly made of hydrogen and helium.
It was later described as "the most brilliant PhD thesis ever written in astronomy".
The jemalloc memory allocator was first conceived in early 2004, and hasbeen in public use for about 20 years now. Thanks to the nature of open source software licensing,jemalloc will remain publicly available indefinitely. But active upstream development has come to anend. This post briefly desc...

- Summary: The jemalloc memory allocator was first conceived in 2004 and has been in public use for about 20 years. Jason Evans, the creator, describes its development phases, from its initial use in the Lyken programming language to its integration into FreeBSD, Firefox, and Facebook. The allocator underwent significant changes, including the addition of size-segregated regions to address fragmentation issues and the introduction of heap profiling functionality. Facebook's investment in jemalloc led to significant performance improvements and the addition of features like continuous integration testing and comprehensive telemetry. However, with Facebook's rebranding as Meta, investment in jemalloc decreased, and development stagnated. Evans considers "upstream" jemalloc development concluded and reflects on generic failures, including lack of awareness about external uses and the project's inability to retain primary contributors from other organizations.

Historian here, you can call him a fascist.

Frequent reauth doesn't make you more secure

- Summary: Frequent reauthentication doesn't enhance security; instead, it interrupts work, frustrates users, and can weaken security. The practice of forcing users to log in frequently is outdated. Modern security should focus on continuous verification rather than frequent logins. Tools like device posture checks and SCIM-based access control can update security attributes and policies in real-time without user interaction. Tailscale advocates for adaptive and intelligent security that doesn't rely on frequent logins but instead verifies users at critical moments, reducing friction and enhancing safety. This approach allows for instant revocation of access if a device is lost or compromised and automatic updates to access based on changes in user roles or employment status.
Denmark's Digital Ministry is replacing Microsoft services with LibreOffice and Linux.
Solarpunk offers an unapologetically optimistic vision of the future that imagines a radically different societal structure in harmony with nature.
All is not lost.
We do still have options, good choices we can make that will lead to a better – or at least less disastrous – future.

Imagine being surrounded by lush natural landscapes, buildings covered with verdant plants and vegetation complete with rooftop gardens, and cities that are completely powered by clean energy. Imagine having our technologies built in harmony with nature and shared equally with everyone on the planet. This is what our world should look like as envisioned by the solarpunk movement.

The hardest post I've ever written.
I moved to Toronto a decade ago in large part *for GO expansion and electrification*, the news this week is sad, but I've been living with it for a long time.
I wrote a long, detailed, emotional blog post about the situation, and where we go from here: https://nextmetro.substack.com/p/toronto-a-huge-setback-for-the-greatest
