  • When your eyes are open and unobscured, light is coming in from every direction. The lens is shaped in such a way that light rays parallel to the eye’s axis are focused on the macula, the center of your sharp vision. A near-sighted (myopic) eye focuses those parallel rays in front of the retina, and a far-sighted (hypermetropic) eye focuses them behind. The farther away the ray is from the eye’s axis, the more it is refracted by the lens, and the more obvious its out-of-focus-ness becomes if the lens has an incorrect shape.

    Corrective eyewear works by refracting the light before it enters the eye and essentially cancelling out the lens’ imperfections.

    A pinhole works by obscuring light rays that are farther from the axis and contribute to the blurry image, only letting through light rays that are near the axis, already aligned more or less with the macula, don’t have to be refracted as sharply, and don’t contribute as much to the blurry image. This is why the camera obscura works, and why apertures in modern photography are used to control both the image’s exposure and the strength of the depth of field.





  • It makes perfect sense to do this. You have no idea how much extra work it is to maintain a Linux-native version that works predictably across the entire range of Linux machine configurations. Factorio has one guy, raiguard (hallowed be his name), in charge of the Linux build, and he wrote a blog post about the unique challenges of supporting the Linux native build.

    Proton is already known to be perfectly capable of running most games as good as or even better than Windows. Game developers can defer the issue of compatibility and focus on developing the game instead of having to implement client-side decorations for GNOME users.



  • No.

    The local machine boots using PXE. Clonezilla itself is transferred from a TFTP server as a squashfs and loaded into memory. When that OS boots, it mounts a network share using CIFS that contains the image to be installed. All of the local SATA disks are named sda, sdb, etc. A script determines which SATA disk is the correct one (must be non-rotational, must be a specific size and type), deletes every SCSI device (which includes ATA devices too), then mounts only the chosen disk to make sure it’s named sda.

    Clonezilla will not allow an image cloned from a device named sda to be written to a device with a different name – this is why I had to make sure that sda is always the correct SSD.

    It’s a large household trash bin with two wheels, a handle, and a lid, usually made out of plastic. You can tilt it onto the wheels for easier transportation. It often has receptacles that a garbage truck can hook into when emptying.

    The “wheelie bin” expression is (probably) Irish.

    There is a variant of the chair that have gaps in the seat to prevent rain from pooling. While it’s a useful feature, it also presents a danger because sitting on them can cause the gaps to widen, allowing things like testicles to pass through, and get caught when the person stands up.

    Enjoy picturing that thought.
