Looking for balance in IT's inner path.
What? One of my systems (running Manjaro) had an update. This process updated the kernel to linux510. It happens to be that this kernel, with my laptop (Asus Ideapad), produces the flip_done timed-out error: [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:62:crtc-0] flip_done timed out The problem Ok, the problem is: the kernel won´t load at all!

Or: why Devops should be good at story-telling? Someone told me that Devops' work is invisible (even ungrateful for the Devops practitioner). I prefer to think of it as subtle. Which implies, we Devops, must be good story tellers, so we can spread the word. (and show stakeholders the importance of our work) About the... Continue Reading →
