Quantum Computers Are Not a Threat to 128-bit Symmetric Keys There is no need to update symmetric key sizes as part of the post-quantum transition, due to the details of how Grover's algorithm scales. Most authorities agree.

There are no technical or compliance reasons to double the size of symmetric keys in response to the threat of quantum computers.

This common misunderstanding of Grover's algorithm risks wasting limited resources that should go towards deploying actually urgent post-quantum algorithms.

NASA astronaut Christina Koch sits in an U.S. Navy MH-60S Seahawk attached to Helicopter Sea Combat Squadron (HSC) 23 on the flight deck of the San Antonio Class amphibious transport dock USS John P. Murtha (LPD 26) after returning from space on Apr. 10, 2026.

This picture of Astronaut Christina Koch after the Artemis landing is frankly incredible and beautiful.

A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

More context on this #Artemis II image:

* This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right

* The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon:

ECMAScript Euphoria! 🎉

We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4.

Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

New Blog Post: The engagement of SAP Community Posts is in free fall and the (perceived) quality of the posts is declining.
Views per post have been in free-fall since 2020, with a few viral hits masking a long tail of unread content.
I’m running out of optimism.

From the mob who don't know how tariffs work, not surprising they don't know what a trade deficit is and thought it was tariffs. Bunch of clowns.

Check out HBO’s #Surveilled. Yes, you heard about #Pegasus. But unless you are involved, not on this level. IMO issue is that a public commercial company is operating in spy grey zone without regulation. Public commercial companies need to be accountable, also by minority/targeted individuals.
