Learn why the Excel AGGREGATE function fails with arrays and how to fix value errors using helper columns or dynamic LAMBDA and BYROW formulas.

Agentic AI is now a core part of the engineering process, driving massive execution leverage and helping us generate more code than ever before. Yet, a difficult question I’ve increasingly heard from ...

Problem Statement: Given an array, we have to find the smallest element in the array.

Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary ...

Abstract: In recent years, space–time coding metasurfaces and antennas have attracted widespread attention in both radar and sensing technologies due to their low manufacturing costs, simple ...

Vibe coding is great for the App Store economy, but Apple is still wary about its use without safeguards in place. It's a fine balance that's going to be hard to maintain. The concept of vibe coding ...

Kiki bills itself as the “array programming system of unknown origin.” We thought it reminded us of APL which, all by itself, isn’t a bad thing. The announcement post is decidedly imaginative. However ...

Sam Altman sits with his legs pretzeled in an office chair, staring deeply into the ceiling. To be fair, the new OpenAI headquarters—a temple of glass and blond wood in San Francisco’s Mission ...

Not only is it hard to follow what’s really going on, but not checking constantly can also lead to problems, as agents might stop to ask you something and you won’t notice it for minutes or hours.
