Assorted links for Tuesday, June 18:
- Composable data management at Meta
By providing a reusable, state-of-the-art execution engine that is engine- and dialect-agnostic (i.e, it can be integrated with any data system and extended to follow any SQL-dialect semantic), Velox quickly received attention from the open-source community. Beyond our initial collaborators from IBM/Ahana, Intel, and Voltron Data, today more than 200 individual collaborators from more than 20 companies around the world participate in Velox’s continued development.
- New warp drive concept does twist space, doesn’t move us very fast
A team of physicists has discovered that it’s possible to build a real, actual, physical warp drive and not break any known rules of physics. One caveat: the vessel doing the warping can’t exceed the speed of light, so you’re not going to get anywhere interesting any time soon. But this research still represents an important advance in our understanding of gravity.
- Biggest Windows 11 update in 2 years nearly finalized, enters Release Preview
Windows 11 24H2 includes an updated compiler, kernel, and scheduler, all lower-level system changes made at least in part to better support Arm-based PCs. Existing Windows-on-Arm systems should also see a 10 or 20 percent performance boost when using x86 applications, thanks to improvements in the translation layer (which Microsoft is now calling Prism).
There are more user-visible changes, too. 24H2 includes Sudo for Windows, the ability to create TAR and 7-zip archives from the File Explorer, Wi-Fi 7 support, a new “energy saver” mode, and better support for Bluetooth Low Energy Audio. It also allows users to run the Copilot AI chatbot in a regular resizable window that can be pinned to the taskbar instead of always giving it a dedicated strip of screen space.

- Another US state repeals law that protected ISPs from municipal competition
Minnesota this week eliminated two laws that made it harder for cities and towns to build their own broadband networks. The state-imposed restrictions were repealed in an omnibus commerce policy bill signed on Tuesday by Gov. Tim Walz, a Democrat.
Minnesota was previously one of about 20 states that imposed significant restrictions on municipal broadband. The number can differ depending on who’s counting because of disagreements over what counts as a significant restriction. But the list has gotten smaller in recent years because states including Arkansas, Colorado, and Washington repealed laws that hindered municipal broadband.
The Minnesota bill enacted this week struck down a requirement that municipal telecommunications networks be approved in an election with 65 percent of the vote. The law is over a century old, the Institute for Local Self-Reliance’s Community Broadband Network Initiative wrote yesterday.
