The following is a listing of pictures electronically placed on the phonograph records which are carried onboard the Voyager 1 and 2 spacecraft. The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim. Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions, in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played. The 115 images are encoded in analog form. The remainder of the record is in audio, designed to be played at 16-2/3 revolutions per minute. It contains the spoken greetings, beginning with Akkadian, which was spoken in Sumer about six thousand years ago, and ending with Wu, a modern Chinese dialect. Following the section on the sounds of Earth, there is an eclectic 90-minute selection of music, including both Eastern and Western classics and a variety of ethnic music. Once the Voyager spacecraft leave the solar system, they will find themselves in empty space. It will be forty thousand years before they make a close approach to any other planetary system.

A container image represents binary data that encapsulates an application and all itssoftware dependencies. Container images are executable software bundles that can runstandalone and that make very well defined assumptions about their runtime environment.
Container images are usually given a name such as pause, example/mycontainer, or kube-apiserver.Images can also include a registry hostname; for example: fictional.registry.example/imagename,and possibly a port number as well; for example: fictional.registry.example:10443/imagename.
If you enable the RuntimeClassInImageCriApi feature gate,the kubelet references container images by a tuple of (image name, runtime handler) rather than just theimage name or digest. Your container runtimemay adapt its behavior based on the selected runtime handler.Pulling images based on runtime class will be helpful for VM based containers like windows hyperV containers.
By default, kubelet pulls images serially. In other words, kubelet sends onlyone image pull request to the image service at a time. Other image pull requestshave to wait until the one being processed is complete.
If you would like to enable parallel image pulls, you can set the fieldserializeImagePulls to false in the kubelet configuration.With serializeImagePulls set to false, image pull requests will be sent to the image service immediately,and multiple images will be pulled at the same time.
The kubelet never pulls multiple images in parallel on behalf of one Pod. For example,if you have a Pod that has an init container and an application container, the imagepulls for the two containers will not be parallelized. However, if you have twoPods that use different images, the kubelet pulls the images in parallel onbehalf of the two different Pods, when parallel image pulls is enabled.
When serializeImagePulls is set to false, the kubelet defaults to no limit on themaximum number of images being pulled at the same time. If you would like tolimit the number of parallel image pulls, you can set the field maxParallelImagePullsin kubelet configuration. With maxParallelImagePulls set to n, only n imagescan be pulled at the same time, and any image pull beyond n will have to waituntil at least one ongoing image pull is complete.
As well as providing binary images, a container registry can also serve acontainer image index.An image index can point to multiple image manifestsfor architecture-specific versions of a container. The idea is that you can have a name for an image(for example: pause, example/mycontainer, kube-apiserver) and allow different systems tofetch the right binary image for the machine architecture they are using.
Kubernetes itself typically names container images with a suffix -$(ARCH). For backwardcompatibility, please generate the older images with suffixes. The idea is to generate say pauseimage which has the manifest for all the arch(es) and say pause-amd64 which is backwardscompatible for older configurations or YAML files which may have hard coded the images withsuffixes.
Aside from sculpture and other physical activities that can create three-dimensional images from solid material, some modern techniques, such as holography, can create three-dimensional images that are reproducible but intangible to human touch. Some photographic processes can now render the illusion of depth in an otherwise "flat" image, but "3-D photography" (stereoscopy) or "3-D film" are optical illusions that require special devices such as eyeglasses to create that illusion of depth.
Copies of 3-dimensional images have traditionally had to be crafted one at a time, usually by an individual or team of artisans. In the modern age, the development of plastics and other technologies made it possible to create multiple copies of a 3-dimensional object with less effort; the advent and development of "3-D printing" have expanded that capability.
The word 'image' is also used in the broader sense of any two-dimensional figure such as a map, graph, pie chart, painting, or banner.[clarification needed] In this wider sense, images can also be rendered manually, such as by drawing, the art of painting, or the graphic arts (such as lithography or etching), rendered automatically by printing or computer graphics technology, or developed by a combination of methods.
On the other hand, some processes can be used to create visual representations of objects that are otherwise inaccessible to the human visual system. These include microscopy for the magnification of minute objects, telescopes that can observe objects at great distances, X-rays that can visually represent interior structures of the human body (among other objects), magnetic resonance imaging (MRI), positron emission tomography (PET scans), and others. Such processes often rely on the detection of electromagnetic radiation that occurs beyond the light spectrum visible to the human eye, converting such signals into recognizable images.
"Moving" two-dimensional images are actually illusions of movement perceived when still images are displayed in sequence, each image lasting less, and sometimes much less, than a fraction of a second. The traditional standard for the display of individual frames by a motion picture projector has been 24 frames per second (FPS) since at least the commercial introduction of "talking pictures" in the late 1920s, which necessitated a standard for the synchronization of images and sounds.[citation needed] Even in electronic formats such as television and digital image displays, the apparent "motion" is actually the result of many individual lines giving the impression of continuous movement.
The nature of images, whether three-dimensional or two-dimensional, created for a specific purpose or only for aesthetic pleasure, has continued to provoke questions and even condemnation at different times and places. In his dialogue The Republic, the Greek philosopher Plato described our apparent reality as a copy of a higher order of universal forms. As copies of a higher reality, the things we perceive in the world, tangible or abstract, are inevitably imperfect. Book 7 of The Republic offers Plato's "Allegory of the Cave," where ordinary human life is compared to being a prisoner in a darkened cave who believes that shadows projected onto the cave's wall comprise actual reality.[citation needed] Since art is itself an imitation, it is a copy of that copy and all the more imperfect. Artistic images, then, not only misdirect human reason away from understanding the higher forms of true reality, but in imitating the bad behaviors of humans in depictions of the gods, they can corrupt individuals and society.[according to whom?]
