• Netflix Uncovers TCP Bugs Within The Linux & FreeBSD Kernels - Phoronix — As Netflix's first security bulletin for 2019, they warned of TCP-based remote denial of service vulnerabilities affecting both Linux and FreeBSD. These vulnerabilities are rated "critical" but already being corrected within the latest Git code.
• Initial Benchmarks Of Microsoft's WSL2 - Phoronix — Since the release of WSL2 as a Windows 10 Insider Preview update this week, we've been putting the new Windows Subsystem for Linux 2 under some benchmarks compared to WSL1 and bare metal Linux. While WSL2 has improved the I/O performance thanks to the new Hyper-V-based virtualization approach employed by WSL2, the performance has regressed in other areas for running Linux binaries on Windows 10.
• The Future of Docker Desktop for Windows - Docker Engineering Blog — ith WSL 2 integration, you will still experience the same seamless integration with Windows, but Linux programs running inside WSL will also be able to do the same. This has a huge impact for developers working on projects targeting a Linux environment, or with a build process tailored for Linux. No need for maintaining both Linux and Windows build scripts anymore! As an example, a developer at Docker can now work on the Linux Docker daemon on Windows, using the same set of tools and scripts as a developer on a Linux machine
• Check Out the Snap Store's New Distro Install Pages - OMG! Ubuntu! — In an effort to improve the experience for users wishing to install Snap apps on non-Ubuntu distributions, the Snapcraft team have launched distro-specific store pages for Snap apps.
• Call for testing: chromium-browser deb to snap transition - Desktop - Ubuntu Community Hub — The chromium browser has been available as a deb package for all supported Ubuntu releases and as a snap since version 60, and the time has come to start transitioning away from the debs.
• Atari VCS goes on $250 pre-order with Linux running on Ryzen R1000 — Atari has opened $250 pre-orders for its Atari VCS retro game console, which will run Linux on the new AMD Ryzen R1000 SoC. Indiegogo backers are set for a December release while new orders will be fulfilled in Mar. 2020.
• A EALLY Weird PC… - System76 Thelio Review — There’s more than one company that makes its own operating system and hardware, and today, we’re taking a look at System76’s Thelio, an open source design you can build yourself.
• Fedora · zfsonlinux/zfs Wiki — Only DKMS style packages can be provided for Fedora from the official zfsonlinux.org repository. This is because Fedora is a fast moving distribution which does not provide a stable kABI. These packages track the official ZFS on Linux tags and are updated as new versions are released.
• Replacing a failed drive in ZFS on FreeBSD – Dan Langille's Other Diary — One of my new hard 3TB drives was acting up. I removed it and sent it off to be replaced. In the meantime, I received some 5TB drives and I added one of them into the existing vdev of the zpool.
• Sharing ZFS Datasets Via NFS | Programster's Blog — The great thing about ZFS is that it is very easy to split your "pool" into as many datasets as you like. Each dataset is treated like its own filesystem, with its own rules and settings, which means with regards to sharing over NFS, that you can share more securely as client's will not be able to reach out of the bounds of that dataset/filesystem that you decided to share.
• How to easily configure WireGuard - Stavros' Stuff — At its core, all WireGuard does is create an interface from one computer to another. It doesn’t really let you access other computers on either end of the network, or forward all your traffic through the VPN server, or anything like that. It just connects two computers, directly, quickly and securely.
• Use Public Key Authentication with SSH — Password authentication is the default method most SSH (Secure Shell) clients use to authenticate with remote servers, but it suffers from potential security vulnerabilities, like brute-force login attempts. An alternative to password authentication is public key authentication, in which you generate and store on your computer a pair of cryptographic keys and then configure your server to recognize and accept your keys
• rga: ripgrep, but also search in PDFs, E-Books, Office documents, zip, tar.gz, etc. - phiresky's blog — rga is a line-oriented search tool that allows you to look for a regex in a multitude of file types. rga wraps the awesome ripgrep and enables it to search in pdf, docx, sqlite, jpg, zip, tar.*, movie subtitles (mkv, mp4), etc.
• pindexis/marker: The terminal command palette — Marker is a command palette for the terminal. It lets you bookmark commands (or commands templates) and easily retreive them with the help of a real-time fuzzy matcher.

• Suse is once again an independent company — Few companies have changed hands as often as Suse and yet remained strong players in their business. Suse was first acquired by Novell in 2004. Novell was then acquired by Attachmate in 2010, which Micro Focus acquired in 2014. The company then turned Suse into an independent division, only to then announce its sale to EQT in the middle of 2018.
• SUSE is now an independent company after being acquired by EQT for $2.5 billion | Packt Hub — As the company has been owned by EQT, so according to few users it’s still not independent. One of the users commented on HackerNews, “Being owned by a Private Equity fund can really not be described as being “independent”.

• Full-system dynamic tracing on Linux using eBPF and bpftrace — What if you want to trace what happens inside a system call or library call? What if you want to do more than just logging calls, e.g. you want to compile statistics on certain behavior? What if you want to trace multiple processes and correlate data from multiple sources? In 2019, there's finally a decent answer to that on Linux: bpftrace, based on eBPF technology.
• Learn eBPF Tracing: Tutorial and Examples — eBPF can be used for many things: network performance, firewalls, security, tracing, device drivers, and more!
• IO Visor Project — The IO Visor Project is an open source project and a community of developers to accelerate the innovation, development, and sharing of virtualized in-kernel IO services for tracing, analytics, monitoring, security and networking functions. It builds on the Linux community to bring open, flexible, distributed, secure and easy to operate technologies that enable any stack to run efficiently on any physical infrastructure.
