Entry #697

Alert! - Dan Gordon

https://www.dmgordon.org/cover/

 This website will be shutting down in 2026, and after March 1 no new covering designs will be accepted.

Dan Gordon’s Home Page

This page is for my mathematical work, including publications and The La Jolla Combinatorics Repository, which contains online databases of covering designs, difference sets, Steiner systems and circulant weighing matrices.

Alert!

I first put covering designs online in 1996. After 30 years, it’s time for this website (and eventually me) to be retired. As of March 1, 2026, I will stop accepting covering design submissions to the website. All the databases will be frozen, and the github and zenodo pages updated with the final versions of each one.

This website will stay up for some indeterminate amount of time, after which it will be replaced with this page. The data is being made available under a CC BY 4.0 license, meaning that anyone can use it however they see fit, as long as they give credit and make it clear what changes have been made.

It’s been a lot of work over the years to maintain these databases, and I’ve learned a lot more about HTML, MySQL, PHP, and AWS than I ever wanted to. But I’m grateful for all the feedback I’ve received, and the hundreds of researchers who have contributed tens of thousands of covering designs.

NY Pick 3 for this week

NY Pick 3
Method  (cold / hybrid / positional), without trying to “predict” results.

036 · 048 · 347 · 368 · 406 · 480 · 638 · 639 · 708 · 804 · 835 · 860 · 346 · 684

Overall structure (first pass)

✔️ No triples
✔️ No explicit doubles (AAB, ABB)
✔️ Strong dominance of ABC (all digits different)
✔️ Good distribution across low / mid / high digits

>> This already indicates a cold / controlled hybrid set, not a “hot” set.
Block-by-block analysis

1 - Low-dominant group (0–3)

036 048 406 480

✔️ Zeros are well distributed
✔️ Not clustered around common hot pairs
✔️ Good candidates for midday and early-cycle plays

2 - Balanced mid-range

347 368 346

✔️ Strong positional diversity
✔️ No repeated positional pairs
✔️ Solid structural integrity

3 - Upper-mid / high support

638 639 684

✔️ High digits used as structure, not overload
✔️ Avoids recent saturation patterns
✔️ Works well as cycle-extension coverage

4 - Extreme high / edge coverage

708 804 835 860

✔️ Good use of digit separation
✔️ Zero breaks hot clusters
✔️ These often show better performance in evening draws

Probability and likelihood

People often mix up probability and likelihood, but they’re not the same.

Probability is used to predict outcomes when the model is known—like lottery draws, dice, or cards—where results can be calculated precisely.

Likelihood works the other way around: after outcomes are observed, it’s used to judge which explanation or model best fits the data, often in complex real-world situations like elections.

Simply put:
Probability predicts outcomes; likelihood evaluates explanations.

Big Ideas 2026 a16z

In December 2025, Andreessen Horowitz (a16z) released its Big Ideas 2026, a multi-part series outlining the most critical problems and innovation roadmaps for the upcoming year. The central theme for 2026 is the transition of AI from "experimentation" to "execution," where governance, infrastructure, and physical-world integration become the primary products. 
Core Themes for 2026
  • AI Moves from Tools to Systems: Innovation is shifting from simple chatbots and copilots to agent-centric systems that can autonomously own outcomes and manage complex, recursive workloads.
  • The Return to the Physical World: After decades of digital dominance, venture capital is flowing back into "American Dynamism"—industries like manufacturing, energy, and logistics, now powered by an AI-native industrial base.
  • Infrastructure for "Agent Speed": Traditional backends built for human interaction are being re-architected for agents that can trigger thousands of tasks per second, necessitating "agent-native" infrastructure that handles massive concurrency. 
Key Category Breakdowns
Category  Big Idea for 2026
Enterprise "Data Entropy" Management: Startups will focus on cleaning and governing the chaotic, semi-structured "sludge" (PDFs, logs, emails) that now limits AI performance.
Crypto Privacy as the Ultimate Moat: Privacy features will become essential for onchain finance, creating strong network effects because "bridging tokens is easy, bridging secrets is hard".
Consumer "The Year of Me": Products will move away from mass-production toward extreme personalization in education, health, and media.
Industrial Physical Observability: The revolution that brought transparency to software code will come to the physical world via networked sensors and cameras monitoring cities and power grids.
Creative Immersive/Interactive Video: Video will stop being passive and start feeling like a 3D environment or "virtual world" that users can step into and interact with.
Specific Market Shifts
  • Cybersecurity: AI will finally close the hiring gap by automating "soul-crushing" level-1 log review work, freeing human teams for high-stakes threat hunting.
  • Financial Services: Institutions will begin letting legacy COBOL-based contracts lapse to implement AI-native alternatives that parallelize thousands of tasks, such as mortgage underwriting.
  • Education: Predictions include the rise of the first AI-native university, an adaptive academic organism where reading lists and learning paths evolve nightly based on data feedback loops.
  • Stablecoins: Expected to transition from a niche financial tool to the "foundational settlement layer for the internet," facilitating real-time cross-border payments for workers and merchants.
