What would happen to the solution of primal SVM problem we had 0 in constraint instead of 1
Then $\mathbf{w} = \mathbf{0}$, $b = 0$ satisfies every constraint, but that's not a useful solution.
Stanford Prof. Stephen Boyd has an excellent discussion in lecture 13 of his Convex Optimization …

KKT in a nutshell graphically
The basic idea of the KKT conditions as necessary conditions for an optimum is that if they don't hold at a feasible point $\mathbf{x}$, then there exists a direction $\boldsymbol{\delta}$ that will i …

The proof of equivalent formulas of ridge regression
It's perhaps worth reading about Lagrangian duality and a broader relation (at times equivalence) between:
optimization subject to hard (i.e. inviolable) constraints
optimization with penalties for …
