hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final
((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

We hope you enjoyed the 2026 Marblehead Harbor Illumination and Fireworks! 🇺🇸
First, we would like to thank all the volunteers of the civilian barge patrol, who gave up several hours each during the Fourth to help enforce the security perimeter around the fireworks barge during the day.
We also thank the many businesses, clubs, civic organizations, and individual citizen donors who have contributed to the 2026 fireworks display!

Happy to report that our fireworks barge is already in position this morning and the fireworks are being loaded during the day. There is a chance of thunderstorms later this afternoon, so keep your fingers crossed that they stay away.
Please stay clear of the barge and remain outside the Safety Zone that is marked with orange and pink tetrahedron buoys and patrolled by our volunteer barge patrol vessels that are marked with orange Privileged Vessel flags.

Just one more day and a few more hours until the Marblehead Fireworks to celebrate the 250th birthday of the United States of America 🇺🇸 on this Independence Day 2026!

If you're going by sea… 🛥⛵🚣
Please be aware that a Safety Zone around the barge will be implemented and patrolled on the Fourth of July, and vessels that are too close will be subject to boarding and heavy fines. The Safety Zone will be market with orange or yellow tetrahedron buoys. Coast Guard regulations will be strictly enforced for your safety and those around you.

For recreational drone owners/pilots: please leave your drones at home and do not fly them during the Marblehead Fireworks and Harbor Illumination. Recreational drone usage during these events is strictly prohibited.

Just two weeks until the 4th of July! 🎆
If you are planning to see the fireworks from the water, please note that we now have an interactive tide chart on the boater information page on our Fireworks website:

Utility-scale quantum isn’t just a qubit problem. At scale, the bottleneck is the system: measurements + control under extreme bandwidth & power constraints. Check out my latest article: Scalable Quantum Architecture: Trade‑offs on the Path to Utility Scale linkedin.com/pulse/scalable-…

Complex data transformations get easier when you break them into structured stages, AKA chained data mappings.
Learn how to design multi-stage data pipelines using chained data mappings — a modular approach that simplifies ETL and data integration workflows.

I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

OCR for PDF data extraction is here!
Scanned PDFs no longer have to be a dead-end for data integration. MapForce now includes built-in OCR to extract, map, and transform data from scanned documents—all in one workflow.
