kandi X-RAY | poseidon Summary

poseidon is a Go library typically used in Data Processing, Job Scheduling applications. poseidon has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The Poseidon/Firmament scheduler incubation project is to bring integration of Firmament Scheduler OSDI paper in Kubernetes. At a very high level, Poseidon/Firmament scheduler augments the current Kubernetes scheduling capabilities by incorporating a new novel flow network graph based scheduling capabilities alongside the default Kubernetes Scheduler. Firmament models workloads on a cluster as flow networks and runs min-cost flow optimizations over these networks to make scheduling decisions. Due to the inherent rescheduling capabilities, the new scheduler enables a globally optimal scheduling for a given policy that keeps on refining the dynamic placements of the workload. As we all know that as part of the Kubernetes multiple schedulers support, each new pod is typically scheduled by the default scheduler. But Kubernetes can also be instructed to use another scheduler by specifying the name of another custom scheduler at the time of pod deployment (in our case, by specifying the 'schedulerName' as Poseidon in the pod template). In this case, the default scheduler will ignore that Pod and instead allow Poseidon scheduler to schedule the Pod on a relevant node.

            Use a grid layout with flex on the logo element. using grid-layout you can express how wide you want the columns to be using grid-template-columns: then call the grid-area on each selector with in the grid parent. You may need to tweak a bit to your liking depending on what view ports you are going for.

            Use flex on child items you wish to align in a row. Simple Ul/li for links...

            I think a lot of what you did, specifically around data wrangling, was not necessary, especially since you called d3.hierarchy() and d3.cluster() afterwards. I've replaced this with d3.stratify (which deals with hierarchical data that is not yet in the right format).

            I've also replaced d3.cluster with d3.tree() because it was unclear to me why you'd want to use d3.cluster here. Your data has multiple parents, multiple roots and even floating nodes, and d3 is not meant to deal with that. My workaround has been to attach pseudonodes to every level, so as to make sure that there is only one node and that all nodes are at the right level at all times. To make sure the links were drawn correctly, I've written a custom getLinks function, that can deal with multiple parents.

            I've also written a custom link generator that draws the links somewhat in the way that you want them. d3 doesn't offer much of flexibility here, but you can use the source code for inspiration.

            Edit

            I've changed the logic to be more focused on which "partners" got a child, so both links to the same child are on the same level - like in your picture. I've also drawn the nodes based on how many partners they have, and have given every link an offset so the lines are more distinct.

            I've sorted the nodes so that the real pro-creators are at the top (Zeus), which gives a more balanced and less crowded view.

            Is it possible in MySQL to select strings that contains part that are referenced in another column?
            Asked 2020-Mar-30 at 15:22

            Here is an example, my "reference" is as follow:

            1. | Zeus
            2. | Poseidon
            3. | Apollon

            Then I've got this "to compare" table:

            • Poseidon benediction
            • Random benediction
            • Power from Zeus

            And what I want is some thing like this:

            • Poseidon benediction | Poseidon
            • Power from Zeus | Zeus

            Is there a way to compare the content of the strings with the reference table ?

            What I tried :

            WHERE ... IN (SELECT reference FROM referencetable) but this compare the whole string row so return nothing because it's not contained in the reference table

            WHERE ... LIKE CONCAT("%", (SELECT reference FROM referencetable), "%") but this trhow and error because it work only for one reference value (error says thar ther is more than one row)
