Daniel Kiper

Daniel Kiper works as a software developer for Oracle. Until recently he was one of GRUB maintainers. He is also (a bit) involved in TrenchBoot development. Earlier he worked on the Xen hypervisor BIOS and UEFI boot, kexec, kdump, makedumpfile, crash tool and memory hotplug development. His experience goes into such areas as *NIX, Linux and Windows servers administration, networking including email and DNS configuration, cryptography and many more. Outside of the work he is tirelessly tinkering with computers, time servers, radio, electronics and real size trains in the Polish Association of Railway Enthusiasts. From time to time he also looks high into the sky and tries to understand why aircrafts do not collide midair. At least not so often as it would be expected...
