    Do you remember the little drama with Apple and Google proposing two contradicting ideas about the native CSS way for masonry layout implementation? It is all over, and what we got is a beautiful compromise between the two in a the form of display: grid-lanes. This is super exciting as it has been a frequently requested feature for many years, and the number of downloads of JS libraries like Masonry by David DeSandro just proves this point. I celebrate every moment when I can bin a chunky third party script and replace it with a few lines of CSS.

    • Red Hat Official ☛ Provide access to Red Hat documentation in environments with limited connectivity

      The Red Hat Offline Knowledge Portal is a secure offline version of Red Hat's proprietary knowledge content for our products. It's a pocket library of our award-winning knowledgebase, product documentation, CVEs, errata, and more that's light enough to run at the edge. Offline Knowledge Portal is useful anywhere Red Hat products are used where connectivity is limited, from intentionally disconnected secure sites to situations with planned intervals of low or no bandwidth. As a single small container image, it is easy to install and use, and is compatible with Red Hat OpenShift, Podman, or any OCI-compliant container runtime.

      To both capture the context and minimise distortion the final picture should be just a bit wider than normal human field of view. That is about 50mm for a full-frame camera or 35mm for a typical 1.6 crop camera. You can go a bit wider if there are no better alternatives (as detailed in the scouting section), but be prepared that corners of the image will be distorted and not really usable (but we can fix that in processing step). Or you can go to unusual aspect ratios, like we did in Debconf 10.

      [...]

      Open Hugin (you will also need enblend and enfuse installed) and import your minimal set of images into it. Click the "Align" button and wait a while - the processor will be trying to figure out keypoints in each image and then try to match these points between the images to try to fit them all together into a single projection. To do that it will distort the images. This is the trial and error process part. You may need to add, remove or replace images to get the stiching to work or to work better. You may want to add more of the frame images to fill the ragged holes around the image.

      After initial allignment, go to "Move/Drag" tab and move the image a bit up in the projected field of view and make it a bit more central visually. That will help a bit with the distortions in the near-by people and people in the corners of the image. In the "Crop" tab set the initial crop - leave it generous, you can always crop more in later steps. Do not be afraid of leaving in sizable chunks of black homes, empty skies or grass. All of that can be filled in later as well.
