We show that a continuous action of a quantum semigroup $\mathcal{S}$ on a finite quantum space (finite dimensional $\mathrm{C}^*$-algebra) preserving a faithful state comes from a continuous action of the quantum Bohr compactification $\mathfrak{b}\mathcal{S}$ of $\mathcal{S}$. Using the classification of continuous compact quantum group actions on $M_2$ we give a complete description of all continuous quantum semigroup actions on this quantum space preserving a faithful state.

"Continuous Integration" (CI) has become a standard for proper software development.Checking the integrity of software after changes have been made is essential to ensure its proper functionality.Also, CI helps catch problems introduced by dependencies early when executed on a regular basis (usually done via scheduled CRON runs). Multiple professional providers exist (Travis CI, AppVeyor CI, Circle CI, etc.) which offer CI services to the
