Proxima Centauri Flares: A Lethal Threat to Potentially Habitable Planets?

2025-04-07

New research using the Atacama Large Millimeter/submillimeter Array (ALMA) delves into the millimeter-wavelength flare activity of Proxima Centauri, revealing a worrying picture. Proxima Centauri's flares are far more powerful than the Sun's, and their frequent, intense outbursts could strip away the atmospheres of potentially habitable planets, rendering them uninhabitable. This multi-wavelength study found millimeter flares are far more frequent than previously observed, implying that the extreme-UV radiation environment of Proxima b may be far harsher than predicted. This highlights the urgent need for further multi-wavelength observations to better assess the habitability of planets in red dwarf systems.

The Unfixable Problem of Social Media: A Founder's Confession

The author recounts the failure of their social media platform, Circliq, designed to address the shortcomings of existing platforms. They discovered that the core issue isn't fixable with a new app, but rather stems from the inherent economic structure that incentivizes growth at the expense of user well-being. The pursuit of growth leads to algorithmic manipulation and ultimately, addiction. The solution, the author argues, lies not in building better social media, but in changing the game entirely – through alternative funding models, regulated algorithms, structural separation of social functions and economic incentives, and alternative metrics prioritizing user well-being over engagement.

Gmail's E2EE: A Farce of Encryption?

Google announced end-to-end encryption for Gmail, but its implementation has sparked controversy. The sender encrypts the message with their own key, and the recipient needs a tool called "minimal Gmail" to read it, essentially requiring Gmail usage even without a Google account. This isn't true end-to-end encryption; Google controls access, preventing reading or searching in other clients. The email becomes Google's data, turning 'encryption' into a control mechanism rather than a security enhancement. Users are likely to simply mark these emails as spam.

Programming Languages: Balancing Safety and Power

2024-12-15

This article explores the trade-off between safety and power in programming languages. The traditional view is that powerful languages, like C with its manual memory management, are inherently unsafe. However, the author argues this is outdated. Modern language research shows that greater expressiveness allows for both safety and power. The evolution of macros in Lisp, Scheme, and Racket exemplifies this, demonstrating how improved design can enhance macro capabilities while maintaining safety. Racket's macro system is presented as a best practice, combining hygienic code with powerful manipulation capabilities. The article concludes that safe and reliable systems build more capable and reliable software, and recommends resources for further learning about Racket macros.
