HN discussionAlso related: bash_history is your best productivity tool; https://martinheinz.dev/blog/110 I have a weird story about that. When I was a junior sysadmin I worked for a company providing a SaaS solution for e-commerce. The environment I worked in was bare-metal (as was the style at the time), with a 2 tier network architecture, lots of internal tooling (mostly in Perl fwiw) and highly complex interactions between co…

HN discussionI'd also strongly recommend this view of how Kubernetes uses cgroups, showing similar drill downs for how everything gets managed. Lovely view of what's really happening! https://martinheinz.dev/blog/91 I've been a bit apoplectic in the past that cgroups seemed not super helpful in Kubernetes, but this really showed me how the different Kubernetes QoS levels are driven by similar juggling of different cgroups. I'm n…

HN discussionIt'd be great to see Kubernetes make more extensive use of croups & especially nested croups, imo. The cpuset affinity should build into that layer nicely, imo. More broadly, Kubernetes' desire to schedule everything itself, to fit the workloads intelligent to insure successful running, feels like an anti-partern when the kernel has a much more aggressive way to let you trade off and define priorities and bound reso…

HN discussionSteady now ... The features of Per-Interpreter GIL are - for now - only available using C-API, so there's no direct interface for Python developers. Such interface is expected to come with PEP 554, which - if accepted - is supposed to land in Python 3.13, until then we will have to hack our way to the sub-interpreter implementation. https://martinheinz.dev/blog/97

HN discussionSo first off, your gif looks great! I like your sizing and resolution--that's one of the things I was worried about. Video recording is new to me, so I'd love to know what you record with and resolution settings to pick? I stumbled on this nice blog post on automating these recordings. Maybe a partial solution? https://martinheinz.dev/blog/94 I was thinking of doing a manual process like yours for a start rather tha…

HN discussionI've attended a local CNCF meetup where the chainguard folks presented Wolfi and their related tools to create container images and SBOMs. I was already skeptical of the product, having heard of it before. Unfortunately, attending that talk confirmed to me that they've just re-invented a severely limited version of Nix powered by yaml files that can output SBOMs in a standard format. Their software repository only h…
