Anything related to the FreeBSD/amd64 platform.
UEFI, GPT, Windows 10, FreeBSD 10, and rEFInd
Over the last few days have I experimented with UEFI and GPT in VirtualBox 4.3.26. The goal was to multiboot various operating system, in this case Windows 10 Enterprise Technical Preview 9926 x64 and FreeBSD/amd64 stable/10. First, I thought of persuading the UEFI firmware to always present its boot menu. It sure beats remembering to […]

VirtualBox 4.3.24 is out, so I wanted to try out the UEFI version of the latest FreeBSD/amd64 stable/10 snapshot. It didn’t go well until I realised something important, however strange it may be.

I had a FreeBSD setup I wanted to replicate to another, identical computer. The source system runs ZFS and so should the receiving system. A recursive snapshot in combination with the zfs send and zfs receive commands proved most fruitful.

I have (successfully) attempted to migrate a running i386 stable/9 system into a running amd64 stable/9 system, and attempted to migrate a running i386 stable/10 system into a running amd64 stable/10 system, only to see if these tasks are in fact feasible. The results speaks for themselves, given the boundary conditions outlined below. If your […]

While pondering why darkstat all of a sudden shows corrupted timestamps when running on FreeBSD/amd64 stable/9, I wrote a small program to decode the export format. The program is available using svn co svn://svn.ximalas.info/darkstattype or http://svnweb.ximalas.info/darkstattype/. The license is the 2-clause BSD license.

I came across a blog post by Emil Mikulic on the leap second introduced by the IERS on 1 July 2012. Inspired by Emil Mikulic’s blog post, I created the following short programme.

I’ve been experimenting with carp(4) on FreeBSD/i386 10.0-CURRENT and FreeBSD/amd64 10.0-CURRENT for the past year or so. carp(4) is no longer a pseudo-interface, but rather accessible on every conceivable interface.

Jeg børstet støvet av noen tilårskomne filer forleden dag. Jeg fant et lite program som jeg skrev en gang i 2000. Programmet teller ned til slutten av Unix-epoken. Den opprinnelige definisjonen av datatypen time_t, 32-bit heltall med fortegn, vil få overflyt i midten av januar 2038. Moderne 64-bit OS som FreeBSD/amd64 9.0 har for lengst […]

One of my systems is running FreeBSD/amd64 9.0-STABLE and is using ZFS for all its worth. The amount of installed memory in this system is 8 gibibytes, which should be enough to please even ZFS’ ARC. After a few hours of uptime not everyone are happy, and one of those unhappy guys are GnuPG.
