(Tom) Wireguard is in the linux kernel 5.6 https://www.zdnet.com/article/at-long-last-wireguard-vpn-is-on-its-way-into-linux/
- It is a layer 3 secure VPN. Unlike its older rivals, which it’s meant to replace, its code is much cleaner and simple. The result is a fast, easy-to-deploy VPN.
- Linus Torvalds wrote, “I’m 1000% with Jason on this. The crypto/ model is hard to use, inefficient, and completely pointless when you know what your cipher or hash algorithm is, and your CPU just does it well directly.”
- WireGuard works by securely encapsulates IP packets over UDP. It’s authentication and interface design has more to do with Secure Shell (SSH) than other VPNs. You simply configure the WireGuard interface with your private key and your peers’ public keys, and you’re ready to securely talk.

(Tony) Systemd is changing how home directories are managed in systemd v245
- Systemd-homed has been merged as the latest (optional) fundamental change to Linux distributions in how home directories are handled.
- Systemd-homed makes it easier to support migratable home directories, more self containment within home directories, better password and encryption handling, and other modern Linux home directory features.
- LUKS encrypted volumes, mounting home directories from a CIFS server, FSCRYPT encryption, Btrfs sub-volume handling, and making use of JSON-formatted user records.
(Phil) XCP-ng is officially joining the Xen Project, an open source hypervisor hosted at the Linux Foundation. https://xcp-ng.org/blog/2020/01/28/xcp-ng-join-the-linux-foundation/
- Xen Project is a recognition that XCP-ng is, de facto, the Open Source Xen hypervisor distribution.
- Joining the Xen Project won’t change the XCP-ng Project very much. They will continue to invest resources for innovation and are still recruiting 6 new developers in 2020.
- We can expect more involvement in the Xen Project itself to improve each layer of the XCP-ng Project.
(Tom) Linus Torvalds says “Don’t use ZFS”—but doesn’t seem to understand it
Linus should avoid authoritative statements about projects he’s unfamiliar with.

- discover wireless networks around an already infected Wi-Fi-enabled computer and attempting to brute-force
(Phil) Shellcheck 8 year retrospective https://www.vidarholen.net/contents/blog/?p=859
- ShellCheck is a static analysis tool that points out common problems and pitfalls in shell scripts.
- ShellCheck is generally considered a shell script linter, but it actually started life in 2012 as an IRC bot (of all things!) on #bash@Freenode. It’s still there and as active as ever.
- Since ShellCheck was a hobby project that wasn’t intended to run on random people’s machines, the developer could completely ignore popularity, familiarity, and practicality, and pick the language that was the most fun and interesting. That language is Haskell.
- Lot’s of what I would have done differently. It’s worth a read.
(Tom) Troll Hunter – Mycroft’s Position on Patent Trolls
Patent trolls get paid because short-sighted companies make the decision to pay. Simply put, it is usually cheaper in the short run to pay a troll than it is to litigate. It is also cheaper to give a schoolyard bully your lunch money than it is to visit a doctor. The thing is, once you pay the bully, he’ll just come back again and again and again. Eventually, that lunch money adds up to a lot more than a doctor’s visit. In the long run the best way to deal with a bully is to punch him square in the face. You might take a beating, but if you do it every time? The bully will find easier prey.
