Running Ironic Standalone on RHEL | Adam Young’s Web Log

This is only going to work if you have access to the OpenStack code. If you are not an OpenStack customer, you are going to need an evaluation entitlement. That is beyond the scope of this article.

Introduction to Ironic

The sheer number of projects and problem domains covered by OpenStack was overwhelming. I never learned several of the other projects under the big tent. One project that is getting relevant to my day job is Ironic, the bare metal provisioning service. Here are my notes from spelunking the code.

Adding Nodes to Ironic

TheJulia was kind enough to update the docs for Ironic to show me how to include IPMI information when creating nodes.

Secure NTP with NTS

Many computers use the Network Time Protocol (NTP) to synchronize their system clocks over the internet. NTP is one of the few unsecured internet protocols still in common use. An attacker that can observe network traffic between a client and server can feed the client with bogus data and, depending on the client’s implementation and configuration, force it to set its system clock to any time and date. Some programs and services might not work if the client’s system clock is not accurate. For example, a web browser will not work correctly if the web servers’ certificates appear to be expired according to the client’s system clock. Use Network Time Security (NTS) to secure NTP. Fedora 331 is the first Fedora release to support NTS. NTS is a new authentication mechanism for NTP. It enables clients to verify that the packets they receive from the server have not been modified while in transit. The only thing an attacker can do when NTS is enabled is drop or delay packets. See RFC8915 for further details about NTS. NTP can be secured well with symmetric keys. Unfortunately, the server has to have a different key for each client and the keys have to be securely distributed. That might be practical with a private server on a local network, but it does not scale to a public server with millions of clients. NTS includes a Key Establishment (NTS-KE) protocol that automatically creates the encryption keys used between the server and its clients. It uses Transport Layer Security (TLS) on TCP port 4460. It is designed to scale to very large numbers of clients with a minimal impact on accuracy. The server does not need to keep any client-specific state. It provides clients with cookies, which are encrypted and contain the keys needed to authenticate the NTP packets. Privacy is one of the goals of NTS. The client gets a new cookie with each server response, so it doesn’t have to reuse cookies. This prevents passive observers from tracking clients migrating between networks.

Comfortable Motion: Absolutely Cursed Vim Scrolling - YouTube

Have you ever felt like Vim was too useful and thought hey let's change that, well that's what this dev thought and now we have a plugin called comfortable motion that's adds physics based scrolling into vim, what's physics based scrolling you ask. Well it's scrolling that occurs based on how long you hold down the scroll key.

Running Cassandra on Fedora 32 | Adam Young’s Web Log

Recovering Audio off an Old Tape Using Audacity | Adam Young’s Web Log

One of my fiorends wrote a bunch of music back in high school. The only remainig recordings are on a casette tape that he produced. Time has not been kind to the recordings, but they are audible…barely. He has a device that produces MP3s from the tape. My job has been to try and get them so that we can understand them well enough to recover the original songs. I have the combined recording on a single MP3. I’ve gone through and noted the times where each song starts and stops. I am going to go through the steps I’ve been using to go from that single long MP3 to an individual recording.

Role of Training and Certification at the Linux Foundation

Open source allows anyone to dip their toes in the code, read up on the documentation, and learn everything on their own. That’s how most of us did it, but that’s just the first step. Those who want to have successful careers in building, maintaining, and managing IT infrastructures of companies need more structured hands-on learning with real-life experience. That’s where Linux Foundation’s Training and Certification unit enters the picture. It helps not only greenhorn developers but also members of the ecosystem who seek highly trained and certified engineers to manage their infrastructure. Swapnil Bhartiya sat down with Clyde Seepersad, SVP and GM of Training and Certification at the Linux Foundation, to learn more about the Foundation’s efforts to create a generation of qualified professionals.

Hetzner build machine

This is part of a series of posts on compiling a custom version of Qt5 in order to develop for both amd64 and a Raspberry Pi. Building Qt5 takes a long time. The build server I was using had CPUs and RAM, but was very slow on I/O. I was very frustrated by that, and I started evaluating alternatives. I ended up setting up scripts to automatically provision a throwaway cloud server at Hetzner.

Integer Scaling To Come With Linux 5.11 For Intel Graphics Driver - Phoronix

Going back more than a year there have been Intel "i915" kernel graphics driver patches implementing integer mode scaling support while finally for Linux 5.11 in early 2021 the support will have landed. Intel added integer mode scaling to their Windows graphics driver back in 2019 to provide better clarity when upscaling games (particularly pixel art type content) and other software. The Linux patches materialized in September 2019 for nearest-neighbor integer mode scaling and then seemingly forgotten about. The capability works with Gen11 / Ice Lake and newer.

Linux Support for Variable Refresh Rates On Gen12+ Intel GPUs Is On The Way - LinuxReviews

Intel developer Manasi Navare has submitted a series of patches for the Linux kernel that brings support for variable refresh rates on Intel's latest graphics chips to the Linux kernels i915 driver. The feature is only enabled on Tiger Lake, Sapphire Rapids and newer Intel graphics chips. [...] You do not need a special "Freesync" monitor to use adaptive vertical synchronization, Freesync is just a marketing term used by AMD. The DisplayPort specification has included variable refresh rate (VRR) as an option feature since DP 1.4 and there are many monitors with support for it that are not marketed as "Freesync" or "gaming" monitors. Monitors that are marketed as "Freesync" support the standard DisplayPort VRR protocol so you don't need to use a AMD graphics card to get the benefits of a Freesync monitor. You will soon be able to use one of the very latest Intel CPU's with integrated graphics or one of Intel's upcoming dedicated graphics cards with Freesync monitors on Linux.

Salsa updated to GitLab 13.5

Today, GitLab released the version 13.5 with several new features. Also Salsa got some changes applied to it. [...] It's been way over two years since we started to use Google Compute Engine (GCE) for Salsa. Since then, all the jobs running on the shared runners run within a n1-standard-1 instance, providing a fresh set of one vCPU and 3.75GB of RAM for each and every build. GCE supports several new instance types, featuring better and faster CPUs, including current AMD EPICs. However, as it turns out, GCE does not support any single vCPU instances for any of those types. So jobs in the future will use n2d-standard-2 for the time being, provinding two vCPUs and 8GB of RAM..

Resiliency in Banking : A ‘must have’ for continuity in the new reality (Part 2)

As cited previously, a new business operating environment - whether from an increasingly demanding customer ecosystem or as a result of external events - has necessitated new approaches to understand challenges, adapt, focus, and formulate the new normal. In addition to shifts in the ways consumers interact with banks, internal cultural reluctance to change can be an obstacle. Banking organizations have recognized the need for new operational approaches, but also have often been cautious in light of inherent risks - especially when combining a cloud, data center and on-premises model.

[Old] Mozilla WebThings To Become An Independent Open Source Project

Mozilla has announced that Mozilla WebThings is being “spun out” as an independent open source project. It means that WebThings is no longer going to be a direct project from Mozilla. The company says that it’s winding down its direct investment in WebThings. This transition will happen to stabilize the WebThings gateways around the world. Now, WebThings is getting an independent domain and will work on the web of things, independent of Mozilla.

Firefox on Fedora with OpenH264 – Martin Stransky's Blog

Firefox on Fedora which sits in the updates [F32][F31] right now comes with enabled OpenH264 Cisco decoder for video playback and fdk-aac-free used for audio decoding. It’s implemented by GMP (Gecko Media Plugin) API so the OpenH264 is not used through ffmpeg library but Firefox sandboxed interface, the same as Firefox uses for Widevine CDM plugin. The OpenH264 GMP video playback is a fallback solution when system ffmpeg is missing and internal ffvpx library can’t decode the stream, so ffmpeg from RPM Fusion is always a better alternative if you can install it. The video streams are decoded by system wide OpenH264 2.1.1 which is shipped by Fedora as mozilla-openh264 rpm package. Even if Mozilla OpenH264 (1.8.1) plugin is installed in your profile and claimed at about:plugins page, the Fedora system one is used.

EU imposes sanctions on GRU officers over ‘Fancy Bear’ cyberattacks

The Council of the European Union has imposed sanctions on two Russian citizens and a military intelligence center due to cyberattacks targeting Germany’s parliament in 2015 and the Organization for the Prohibition of Chemical Weapons (OPCW) in 2018. This was announced in the latest volume of the Official Journal of the European Union. The United Kingdom announced plans to enforce these sanctions, as well. 

Open Education and Artificial Scarcity in Hard Times

The sudden move to remote education by universities this year has forced the inevitable: the move to an online education. While most universities won’t be fully remote, having course materials online was already becoming the norm before the COVID-19 pandemic, and this year it has become mandatory for millions of educators and students. As academia recovers from this crisis, and hopefully prepares for the next one, the choices we make will send us down one of two paths. We can move towards a future of online education which replicates the artificial scarcity of traditional publishing, or take a path which fosters an abundance of free materials by embracing the principles of open access and open education.

The well-worn, hefty, out-of-date textbook you may have bought some years ago was likely obsolete the moment you had a reliable computer and an Internet connection. Traditional textbook publishers already know this, and tout that they have embraced the digital era and have ebooks and e-rentals available—sometimes even at a discount. Despite some state laws discouraging the practice, publishers try to bundle their digital textbooks into “online learning systems,” often at the expense of the student. However, the costs and time needed to copy and send thousands of the digital textbooks themselves is trivial compared to their physical equivalent. 

Hybrid open access risks limiting researchers’ publishing options

In the case of the 34 Nature-branded journals, the first step is a “read and publish” deal with Germany’s Max Planck institutes, allowing affiliated researchers to both access the journals and to publish in them open access. The OA fee that Max Planck will pay is based on a cost of €9,500 (£8,600) per article. The publisher, Springer Nature, says that it is in discussions to allow authors worldwide to publish open access in Nature journals from next year.

The UK alone spends more than £25 million on OA journal publishing annually, but the proportion that goes to large commercial publishers for OA in hybrid journals has increased year-on-year. The average cost for publishing in hybrid journals also continues to increase steadily.

This trend has been evident since Springer Nature launched its leading OA journals, Nature Communications and Scientific Reports. In 2018 alone, these journals received more than £1.6 million from 30 UK research-intensive institutions. In 2019, Elsevier launched 100 new OA journals and the humanities publisher IEEE launched 13.

Cloud Foundry Is A Developer Experience For Kubernetes | Chip Childers

OpenStack Foundation Rebrands as Open Infrastructure Foundation

Also announced at the Open Infrastructure Summit was the OpenStack Victoria open source cloud platform, with improved integration with Kubernetes and enhanced IPv6 support. / In a keynote at the event, Thierry Carrez, vice president of engineering at the Open Infrastructure Foundation, said his personal definition for cloud native is applications designed to run on programmable infrastructure. "Cloud native requires programmable infrastructure, and open infrastructure provides an open source solution for that," Carrez said. "So cloud native and open infrastructure really go together like bread and butter."

OpenStack Foundation transforms into the Open Infrastructure Foundation

The writing was on the wall two years ago. The OpenStack Foundation was going to cover more than just the OpenStack Infrastructure-as-a-Service (IaaS) cloud. Today, that metamorphosis is complete. The Foundation now covers a wide variety of open-source cloud and container technologies as the Open Infrastructure Foundation.
