kandi X-RAY | luna Summary

luna is a Python library typically used in Devops, Continuous Deployment, Nodejs, Ansible, Docker applications. luna has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Luna uses the BitTorrent protocol to provision nodes. As such, every booting node helps the others to boot. Once a node is fully booted it stops being a torrent seeder and other nodes can no longer use it to download the image. The torrent client only acts in the initrd environment. Luna does not require any additional services to run on a node. By default it changes very a limited number of files on provisioned nodes. It us usually limited to /etc/hostname and /etc/sysconfig/network-scripts/ifcfg-* files. Image size is 1GB. Provisioning node is equiped with a 1Gb ethernet interface. In a cluster of 300 nodes. Boot time using luna has been measured to be aproximately 5 minutes. This includes BIOS POST procedures and all starting systemd services.

            Weird bug when displaying image
            Asked 2021-Jun-10 at 09:12

            Using next.js and Tailwind, I'm trying to place a logo in the upper right corner of the viewport, which I do successfully if said logo is simply a text.

            However, whenever I try to display the logo with an img or svg tag it simply doesn't show.

            What's even weirder, is that if I keep the text ('a' tag), the logo shows underneath.

            I don't know what I'm missing here.

            This works (but I don't want the text):

            Instead of the platform dependent install units like org.eclipse.core.filesystem.linux.x86_64, org.eclipse.core.filesystem.win32.x86, etc. you should add the install unit that contains the platform dependent units as children (with platform specific filters).

            Values of member struct get lost after being passed to a function as a pointer
            Asked 2021-May-29 at 12:25

            Summary:

            I have an issue where my pointer inside a struct gets randomised after being passed to the function.

            So I pass the original struct with the pointer being in-tact (I checked it there and it works), but after being passed to the function the stated pointer doesn't work anymore. The pointer points to the same address, but the content of the struct is lost and randomised without any prior data still existing.

            Note: All of the signatures like ph_ReturnTypeInt are just specialised types aka. structs where I added additional data which don't matter much in this case, except for the function pointer signatures

            Note 2: Since it's a lot of code that might be unimportant I tried to explain what is what, but here the GitHub link if you need it. Else thank you if you can help me ^^

            The way you're doing it now is comparing the complete dict entry for the JSON data with the complete dict entry of the other data. This will never match as these have separate keys, so the dicts are by defenition different.

            You need to compare exact keys for both dict entries, fe:

            Objects beyond the far clipping plane are rendered in perspective view
            Asked 2021-May-23 at 21:42

            I see objects beyond the far clipping plane in perspective projection and I don't think this is how it's suppose to work, so can someone give me an explanation why do I see objects beyond the far clipping plane such as a grid in this example.

            The orthogonal projections works fine btw

            Answered 2021-May-23 at 21:42

            I think you're thinking of the maximum view distance as being consistently 900 units away from the camera/eye position. If that was the case, it wouldn't be a clipping plane at all, it would be a curve - a sector of a sphere.

            In reality the view frustum is a truncated pyramid made up of 6 planes. When the far plane is set to 900, then the view distance for the pixel in the centre of the view is 900, but the view distance at the corners is much higher (how much higher depends on the FOVs - you could work it out with a bit of trig).

            So as you turn your camera left and right, an object approx 900 units away from the camera will come in and out of view as it intersects the far plane.

            To achieve this you can use map() to build an array of objects from the checkboxes. You can then provide that array to the data property of the AJAX request. Then in your PHP code you can loop through that array and perform whatever actions you require on the data of each row. Try this:

            You can wrap your existing query() in another query() like this:

            =query( query(A1:K, "select K, A, count(K) where K is not null group by K, A", 1), "select Col1, count(Col3) group by Col1", 1 )

            This will get the count of uniques per month.
