K8s was written by a hopeful public cloud giant to cut off the dominant public cloud giant in the container orchestration space. It shouldn't be surprising that it is very oriented around VMs hosted and manged by public cloud providers

The official VMware take, at least while we were there, was that the vmkernel itself was a binary only kernel module loaded by the Console OS's Linux kernel, and as such was no different than the binary-only Nvidia driver. This was a

La Costena is still around, it just moved further down Middlefield towards Sunnyvale, right before Ellis. Sun had a similar app that would fax orders to Tony and Alba's pizza, though that closed a few years ago.

The B-52 had this as well. It was used to augment thrust for takeoff, especially on hot days. It was as simple as pumping water into the compressor stage, cooling the air after the compressor had heated it. This allowed more fuel to be bu

Never worked at Apple specifically, but every place I've worked had little to no docs on internal tools. The expectation was that you'd go ask the person who wrote it, or absorb the tribal knowledge as part of on-boarding. There

I have this conspiracy theory that I half believe: it was all a ruse. Apple knew that there would be huge pushback against a walled garden appstore with Apple in absolute control, and huge pushback on them taking a 30% cut. So they started

People have different opinions on EFI, but in the time before the modern C++ ABI, every compiler (and often different versions of the same compiler) generated code with different ABI expectations, which made libraries and software distribut

If cut-through is enabled in the switch, it won't even drop on bad checksum, since by the time the switch can tell the checksum is wrong, it has already forwarded the entire packet.

Early on, Linux supported initrd, which was just a ramdisk with a FS image written to it and mounted. Later, initramfs came along, which is all anyone uses anymore. It is a cpio archive that is extracted onto a special form of tmpfs. One

After the graphics driver moved out of it and into the kernel, it probably no longer needs the ability to turn off interrupts and read and write legacy IO ports.

There were a bunch of reasons. One important one is that accessing the PCI config space via IO ports 0xCF8/0xCFC is racy with the kernel, since a read or write requires writing the BDF address to 0xCF8, and then reading/writing th
