We Get Letters We Get Letters By Michael W Lucas Dear Letters Column, My employer has dozens of servers, and I don’t know how many operating systems. One of them has an uptime longer than I do, and nobody dares touch it. But some doofus left a computer magazine in the bathroom, the boss found […]

Embedded FreeBSD: Breadcrumbs Embedded FreeBSD: Breadcrumbs By Christopher R. Bowman I’ve been using FreeBSD for almost 3 decades now. I first installed FreeBSD in the early 1990s because the package system made it really easy to install versions of the free CAD software I was using at the time to build my first silicon chips […]

In Memory of Mike Karels In Memory of Mike Karels We are deeply saddened about the passing of Mike Karels, a pivotal figure in the history of BSD UNIX, a respected member of the FreeBSD community, and the Deputy Release Engineer for the FreeBSD Project. Mike’s contributions to the development and advancement of BSD systems […]

Letter from The Foundation Letter from The Foundation Dear Readers, Welcome to the 2024 May/June issue! As I’m writing this, I’m listening to the FreeBSD Day livestreams from community members. It’s been interesting hearing the different stories on how folks got involved, how they are using or contributing to FreeBSD, and what they are excited […]

Submitting GitHub Pull Requests to FreeBSD Submitting GitHub Pull Requests to FreeBSD By Warner Losh The FreeBSD Project recently started supporting GitHub pull requests (PRs) to make it easier to contribute. We found that accepting patches via our bug tracker Bugzilla resulted in far too many useful contributions being ignored and growing stale, so contributors […]

Vault Vault By Dave Cottlehuber Working from home is the new normal. But from a security perspective, things just got a lot more complicated. Gone are the secure offices with carefully manicured security perimeters and 24×7 physical security. Security professionals talk about the categories of risks we care about as our “threat landscape”, or “security […]

rdist rdist By Cy Schubert What is RDIST? To quote the man page, “rdist is a program to maintain identical copies of files over multiple hosts.” rdist is a general-purpose tool that can be utilized for multiple purposes, such as maintaining consistent copies of files across the network, like rsync and unison do, or as […]

mfsBSD in Base mfsBSD in Base By Soobin Rho mfsBSD is an in-memory FreeBSD. What makes mfsBSD different is that it runs an instance of FreeBSD completely in memory — hence the mfs (memory file system). Of course, this means we can boot into FreeBSD without affecting our existing drives at all when using mfsBSD. […]

Git_Experience_Practical_ports By Benedict Reuschling Version control has been around for a long time. Having a way to keep a certain version of a file in a state where it is retrieved is the start of our journey. After all, that’s what backup software is for. Some people use version control systems (VCS) that way, but […]
