Everybody knows that sysadmins are impossibly busy people. Consequently, it sometimes seems they are superhuman. The sysadmin's dirty secret, the same one shared by many open source users, is that they don't actually do all of the work it looks like they've done.

I have spent the first three parts of this series describing the evolution and current state of Flash storage. I also described how to configure an NVMe over Fabric (NVMeoF) storage network to export NVMe volumes across RDMA over Converged Ethernet (RoCE) and again over native TCP. But what does the future of memory technologies look like? As memory technologies continue to evolve, the method in which you plug that technology into your computers will evolve with it.

Recently, I bought and started using a Tuxedo Book BC1507, a Linux laptop computer. Ten years ago, if someone had told me that, by the end of the decade, I could buy top-quality, "penguin-ready" laptops from companies such as System76, Slimbook, and Tuxedo, I probably would have laughed.

Often, a kernel developer will try to reduce the size of an attack surface against Linux, even if it can't be closed entirely. It's generally a toss-up whether such a patch makes it into the kernel. Linus Torvalds always prefers security patches thatreally close a hole, rather than just give attackers a slightly harder time of it.

GitLab finds 68% of security professionals feel that less than half of developers can spot security vulnerabilities, but most people feel it's a programmer's job to write secure code.
