  • As cloud native computing rises, it’s transforming culture as much as code

    Most experts say it’s a mistake to think of cloud native computing in technology terms. Rather, it’s a mindset shift based on the assumption that better technology is available in the cloud than inside a company’s data center. Think of cloud native principles as more of a business enables than an infrastructure improvement.

    “The primary benefit is to reduce the time between forming a business idea and delivering it into production,” said John Clingnan, senior principal project manager, middleware, at Red Hat Inc., an IBM Corp. subsidiary. “It can also be critical when businesses are in a pitched battle to implement a concept and out-executing the competition through rapid, incremental change” will determine who wins.

    “Cloud gives you the flexibility to pick and choose which parts of your application to abstract and which to spend your engineering resources on, giving companies the ability to focus on building on their core differentiators,” said Steven Mih, chief executive of Ahana Inc., a startup that provides services around the Presto distributed database platform

Red Hat OpenShift and NVIDIA’s DGX AI computing systems power this private cloud system that delivers intelligent software applications and boosts operational efficiency for RBC and its customers.

  • What we learned shifting Red Hat’s premier event to a virtual experience

    "Learn to pivot" has been the mantra for 2020. Like most businesses, March 2020 was a challenging time for us on the Red Hat marketing team. With COVID-19 spreading across the world, and businesses sending their employees to work from home, it became clear that Red Hat Summit, scheduled to be hosted in April in San Francisco, could not go on as planned.

    By mid-March we were in full pivot mode to change Red Hat Summit, the premier open source technology conference, from an in-person event to a full digital experience. The challenge -- that the event would still immerse our attendees in everything that makes a Red Hat event special. It was certainly an exciting ride, and on April 27, we opened the Summit virtual experience to the world. In the end, we had more than 50,000 attendees from more than 100 countries visit the live environment. We learned a lot of lessons along the way - below are a few successes we had while pulling off this event, and a one tip for improving a virtual experience.

  • 5G core adoption the open way with Red Hat OpenShift

    Red Hat continues to drive support of an open 5G infrastructure to help drive accelerated adoption of cloud-native technologies for our communications service provider (CSP) customers and partners. As operators look to offer new revenue generating services, the importance of scalability, flexibility and security become critical for the smooth evolution of their networks. With this in mind, customers are looking for ways to deploy cloud-native technology with confidence and an open hybrid cloud foundation offers an essential tool for those deployments.

    Red Hat OpenShift delivers the container based platform that provides consistency from the core to the edge. This platform is part of the recently announced HPE Telco blueprint that we collaborated on with Hewlett Packard Enterprise and utilizes Intel® Xeon® processors. CSPs can use the blueprint to implement an open 5G cloud-native core that provides transformation for telco networks and enables CSPs to engage with leading industry ecosystem partners more easily.

  • Hiring! IBM wants mainframe, DBMS and UNIX specialists! How to get skilled in these?

  • Fedora Ambassadors Revamp 2020 — call for volunteers

    In the past times the Fedora Ambassadors Program had some issues, which made the Ambassadors Team feel disheartened and discouraged. This caused the Mindshare Committee to step up and to gather community input to improve the Ambassadors Program, which gave birth to the Fedora Ambassadors revamp proposal and to create a temporary taskforce which would work on the plan of action in the proposal.

  • Madeline Peck: Intern Day is Coming Up

    I hope you are all having a good week! I have to say, writing these blog posts and reflecting on the week and what I’ve done has become a really therapeutic process. Also maybe I’m enjoying myself this week even more, because I’m testing out a Bluetooth keyboard that I got for school and for writing on the go without a laptop.

    Let’s see what have I been up to. Over the weekend I decided to take the plunge and order some stickers with my own design. I had this great drawing in my sketchbook of a plant with a little face on it’s pot, so I redrew it with the right dimensions and higher quality on my iPad and ordered a small batch of die cut stickers, to see the quality and if I want to get more for the future. It was really cool and I’m looking forward to getting them in the mail in the next week or so.

    The process for the Fedora 33 and Fedora 34 wallpapers has started, you can look at the tickets Mo’s created for them here and here. But over the weekend people voted on which scientist/mathematician/inventor/amazing human being for inspiring the wallpaper, and Walter Lincoln Hawkins was chosen for Fedora 33, and Ub Iwerks was chosen for Fedora 34. I compiled a document full of info for all of the options, which I hope was helpful to others, but at least it was helpful to me.

  • Cockpit 224 and Cockpit Podman 20

    Release Candidate versions are available in testing repository for Fedora and Enterprise Linux (RHEL / CentOS) to allow more people to test them. They are available as Software Collections, for a parallel installation, perfect solution for such tests, and also as base packages.

    RPM of PHP version 7.4.9RC1 are available as SCL in remi-test repository and as base packages in the remi-test repository for Fedora 32 or remi-php74-test repository for Fedora 30-31 and Enterprise Linux 7-8.

    RPM of PHP version 7.3.21RC1 are available as SCL in remi-test repository and as base packages in the remi-test repository for Fedora 30-31 or remi-php73-test repository for Enterprise Linux.

  • Using Red Hat Satellite with the LVFS

    A months weeks ago I alluded that you could run the LVFS in an offline mode, where updates could be synced to a remote location and installed on desktops and servers in a corporate setting without internet access. A few big companies asked for more details, and so we created some official documentation which should help. It works, but you need to script things manually and set up your system in a custom way.

  • The central processing unit (CPU): Its components and functionality

    The legacies of earlier designs, such as Babbage's difference engine and the mainframe punch card systems of the 1970s, have a significant impact on today's computer systems. In my first article in this historical series, Computer history and modern computers for sysadmins, I discussed several precursors to the modern computer and listed characteristics that define what we call a computer today.

    In this article, I discuss the central processing unit (CPU), including its components and functionality. Many of the topics refer back to the first article, so be sure to read it if you haven't already.

    The central processing unit (CPU)

    The CPU in modern computers is the embodiment of the "mill" in Babbage's difference engine. The term central processing unit originated way back in the mists of computer time when a single massive cabinet contained the circuitry required to interpret machine level program instructions and perform operations on the data supplied. The central processing unit also completed all processing for any attached peripheral devices. Peripherals included printers, card readers, and early storage devices such as drum and disk drives. Modern peripheral devices have a significant amount of processing power themselves and off-load some processing tasks from the CPU. This frees the CPU up from input/output tasks so that its power is applied to the primary task at hand.

    Early computers only had one CPU and could only perform one task at a time.

    We retain the term CPU today, but now it refers to the processor package on a typical motherboard. Figure 1 displays a standard Intel processor package.

  • Fedora Zine call for submissions

    The Design team is preparing a zine to recognize the amazing work done by everyone here in the Fedora Project. The zine will serve as a guide to future contributors as a sneak peek into what Fedora is all about and what kind of work we do. It’s also a fun way for Fedorans to express and showcase their creativity.

    A zine is an original, self-published mini-magazine that is intended for small circulation. Zines are intended for niche interest groups and communicate that interest through artistic expression. For centuries, zines have been aiding creative movements and artistic expressions all around the world.

  • Language is the OS that runs our thoughts

    I think in tech, it’s really important to get as much inclusive language as we can nailed down as soon as we can. One trend I’ve seen as time has gone on is that we’re abstracting on top of abstractions further and further out. If we can clean up the base it’s all built on top of, that will hopefully mean a lot less issues moving forward as new abstractions need to be named / expressed in language.

    I have seen a lot of pushback against the suggestion that we actively fix some of the language in our code that could enforce old and problematic ideas. I want to talk about why these words are not so benign, and why changing them matters.

  • Cloud platforms lead the way for banking innovation

    Leadership should be ready to embrace new organizational models that help development teams contribute not only new ideas but also to encourage experimentation. Developers in banks should know that it’s okay to experiment, because innovation doesn’t always happen in a planned or serial way. This means encouraging participation and accepting risks — which isn’t easy in an industry that traditionally is hierarchical and risk-averse.

    Within banks, cloud platforms can offer technology needed for banks to be more collaborative and to try out new ideas quickly. That can be critical, given the increased competition, not only from challenger banks, but also from large technology companies who are providing seamless digital banking services with their own platforms.

  • Adobe, IBM and Red Hat Announce Strategic Partnership to Advance Customer Experience Transformation

    Adobe (Nasdaq: ADBE), IBM (NYSE: IBM) and Red Hat today announced a strategic partnership to help accelerate digital transformation and strengthen real-time data security for enterprises, with a focus on regulated industries. The intent of the partnership is to enable companies to deliver more personalized experiences across the customer journey, driving improved engagement, profitability and loyalty.

    [...]

    "The reality is that today, businesses across industries are operating in an experience first world where it is possible to gain immense value from data if trust and technology flexibility are central to the equation," said Bridget van Kralingen, senior vice president, IBM Global Markets. "It is with these principles as the focus of our partnership – bringing Adobe’s marketing expertise, IBM’s industry domain knowledge and the open innovation of Red Hat –that will give clients the confidence to use their data for new competitive advantage."

  • Red Hat Insights: Vulnerability management

    Author's note: I'm testing the service as part of my job at the Bielefeld IT Service Center (BITS) at Bielefeld University. This article reflects my personal view of Red Hat Insights. Furthermore, I would like to clarify that I am a member of the Red Hat Accelerators community.

    After introducing Red Hat Insights and taking a look at the Advisor, it’s time to take a look at Insights' vulnerability management.

    [...]

    As of today, we don’t have an active vulnerability management. We try to ensure a certain level of security with a patch management for RHEL with Ansible, which I developed with tools included in RHEL and the Ansible Engine. This ensures that available Red Hat Security Advisories are compulsorily installed on all RHEL systems once a month if they are missing.

    Thanks to this patch management, there are only 13 vulnerabilities on the connected test systems, and none of them had a score greater than eight.

    Among the systems listed in the dashboard were systems of a test infrastructure that are not connected to the central patch management and are only irregularly patched. Insights showed me here that the risk is far too great, and that these systems will simply be forgotten. For this reason, these hosts were now immediately included in the patch management.

  • IBM Db2 Warehouse on the Cloud performance validation using OpenShift Container Storage

    IBM delivers solutions designed to mitigate risk and facilitate cloud adoption. In particular, organizations deploying production IBM Db2 workloads need scalable and performant persistent storage that provides their applications with universal application and data mobility. Cloud and container-based solutions must support all of their data, without forcing arbitrary compromises.

    The IBM Db2 team has spent the last several years transforming its delivery and infrastructure toward a Kubernetes-native Db2, tailored for hybrid and multi-clouds and managed by Red Hat OpenShift. One of the most important aspects of this transformation is integration with Red Hat OpenShift Container Storage.

  • Latest release of Red Hat Integration advances connectivity for event-driven, Kubernetes-based applications

    The world of enterprise IT has seen a massive shift over the last decade as cloud computing has changed the way we work and do business. Today, microservices, application programming interfaces (APIs) and containers are the predominant approach to building, connecting and deploying applications, and Kubernetes has become the undisputed standard for managing them at scale in any environment.

    These technologies are core to cloud-native application development, and emerged from the need for organizations to better match the speed of the world around them. The digital experience, delivered through software, has become one of the leading factors in competitive differentiation for companies today. Being able to rapidly respond to dynamic market conditions, incorporate user feedback, or deploy new products and features is crucial to success.

  • New features in Red Hat CodeReady Studio 12.16.0.GA and JBoss Tools 4.16.0.Final for Eclipse 2020-06

For this release, we focused on improving Quarkus– and container-based development and fixing bugs. We also updated the Hibernate Tools runtime provider and Java Developer Tools (JDT) extensions, which are now compatible with Java 14. Additionally, we made many changes to platform views, dialogs, and toolbars in the user interface (UI).

    This article is an overview of what’s new in JBoss Tools 4.16.0 and Red Hat CodeReady Studio 12.16 for Eclipse 4.16 (2020-06).

Fedora Project: RPM, Memory Testing and DXVK

  • Using source-git to maintain packages in Fedora

    Some time ago, we initiated a discussion on the devel list if dist-git is a good place to work. This thread received a great amount of wonderful feedback from you and we are so grateful for every message—it demonstrates the passion of the Fedora community.

    If you are not familiar with how packages are being maintained in Fedora or what dist-git is, let me give you a quick summary. Every Fedora package has a dedicated git repository—a dist-git repository. It contains files needed to compile the sources and produce a binary RPM package which you can install on your Fedora Linux system. As an example, you can look at firefox dist-git repository.

  • Fedora Developers Brainstorming Options For Better Memory Testing

    In looking beyond the massive Fedora 33 release in development, Fedora developers have begun discussing options for allowing better memory testing on their distribution for evaluating possible faulty RAM issues that otherwise often get mixed in with other software bugs and other sporadic behavior.

    Currently Fedora does ship memtest86+ on all installations, but that only works on legacy/BIOS setups and not modern UEFI-enabled systems. It's only the proprietary memtest86 that has UEFI support right now and not the open-source memtest86+. Thus memtest86+ is inaccessible to those on modern platform booting from UEFI, but even if/when memtest86+ offers UEFI support there are other potential obstacles around Secure Boot and similar potential blocks. Additionally, while memtest86(+) is great at rooting out faulty memory scenarios, it can often take some time to spot any issues as another obstacle for end-users.

  • Fedora Looks To Make DXVK Their Default Back-End For Direct3D 9/10/11 On Wine

    Fedora like most distributions ship their Wine packages as-is at the defaults, but for Fedora 33 we could see DXVK used by default on Wine in place of the conventional WineD3D back-end for Direct3D 9/10/11 usage.

    While upstream Wine is working to ultimately support Vulkan with their WineD3D back-end, for now at least DXVK generally offers a far better and more performant experience for gamers by translating D3D9/D3D10/D3D11 calls to Vulkan rather than WineD3D that currently relies upon translating to OpenGL. Steam Play and Proton have shown the success and tremendous capabilities of DXVK while now Fedora is looking at possibly using DXVK by default with their Wine package.

Fedora Workstation 32 is Exceptionally Good

The mythical "Year of the Linux Desktop" never quite came to fruition the way many of us had hoped. Our market share has risen slightly over the years and the developer community at large focuses on Linux as a development platform for backend services because Linux dominates the Datacenter and The Cloud. However, we still struggle to make a dent in that Desktop and Laptop market share quite to the same scale. The Open Source Community is vast, we have massive communities of users and developers who run Linux on their Desktop, Laptop, and various other niche personal computing hardware devices with great success and they are extremely happy doing so, and I count myself among these people. Unfortunately though, I always felt like we weren't "quite there yet" and I see this opinion a lot with Linux Desktop users and I feel there's validity in it with supporting evidence in the form of Linux Desktop users seeking refuge on a Mac, Chromebook, or Windows machine and running Linux in a VM, Container, or using WSL. The frustrations we all had, I shared in from time to time ... until now.

(Yes, I know someone's going to come at me with anecdotal evidence of how they've been happily using Linux on their Desktop for X years without issues and/or considerably less issues than with Operating System Y. That's great, I'm happy for you but this has not been the global experience. Do a couple internet searches and I think you'll see what I'm getting at. Let's continue ...)

  • IBM Research works with industry to architect and prototype trusted container platforms

    When it comes to highly regulated industries, it is critical to maintain high assurances and compliance around computation. Enterprises must ensure that there is governance of data and processes.

    Virtualization and containerization has brought about many benefits to efficiency, adaptability, and scalability of workloads. However, it brings with it challenges in security and compliance.

    For example, workloads might be hosted in an environment that shares a pool of physical platforms in a data center or in multi-tenant cloud. Enterprises have security concerns on whether workloads are being run on platforms that are trustworthy, in terms of the integrity of the platform, its locality and metadata, and its ability to establish itself in a root of trust.

  • Release Team Asks for Feedback on openSUSE Leap "15.2"

    The openSUSE release team is would like feedback from users, developers and stakeholders about the release of the of community-developed openSUSE Leap 15.2 through a survey.

    The survey is available at https://survey.opensuse.org.

    openSUSE Leap 15.2 was released on July 2. Two weeks of people installing the release and using it is a good timeframe to capture fresh ideas and thoughts about how people felt about the release. The survey centers on these two questions: what went well and what didn’t go well?

    That is the question the release team is asking of those who installed and used openSUSE Leap 15.2.

    The team hopes the feedback will provide enough information to help improve the release processes and other elements people found important.

    The survey will close on August 4.

  • DebConf Videoteam Sprint Report -- DebConf20@Home

    DebConf20 starts in about 5 weeks, and as always, the DebConf Videoteam is working hard to make sure it'll be a success. As such, we held a sprint from July 9th to 13th to work on our new infrastructure.

    [...]

    For DebConf20, we strongly encourage presenters to record their talks in advance and send us the resulting video. We understand this is more work, but we think it'll make for a more agreeable conference for everyone. Video conferencing is still pretty wonky and there is nothing worse than a talk ruined by a flaky internet connection or hardware failures.

    As such, if you are giving a talk at DebConf this year, we are asking you to read and follow our guide on how to record your presentation.

    Fear not: we are not getting rid of the Q&A period at the end of talks. Attendees will ask their questions — either on IRC or on a collaborative pad — and the Talkmeister will relay them to the speaker once the pre-recorded video has finished playing.

  • Abhijith PA: Workstation setup

    Recently I’ve seen lot of people sharing about their home office setup. I thought why don’t I do something similar. Not to beat FOMO, but in future when I revisit this blog, it will be lovely to understand that I had some cool stuffs.

    There are people who went deep down in the ocean to lay cables for me to have a remote job and I am thankful to them.

    Being remote my home is my office. On my work table I have a Samsung R439 laptop. I’ve blogged about it earlier. New addition is that it have another 4GB RAM, a total of 6GB and 120GB SSD. I run Debian testing on it. Laptop is placed on a stand. Dell MS116 as external mouse always connected to it. I also use an external keyboard from fingers. The keys are very stiff so I don’t recommend this to anyone. The only reason I took this keyboard that it is in my budget and have a backlit, which I needed most.

  • Best practices for an effective remote team in the world of cloud delivery

    Effective communication between customers, engineers, and project managers is the most critical element of successful cloud delivery. This has always been the case, but it is doubly important in the absence of regular, face-to-face contact.

    For remote teams, instant messaging is an invaluable tool. Internally, we use instant messaging both to keep in touch with one another and to coordinate on projects. However, it’s important to keep these two purposes separate. Maintaining one social channel and one business-focused channel prevents casual conversation from disrupting work.

    For communication with customers, the use of email is the standard tool. Indeed, official design decisions should not be made lightly and need to be documented. In order to avoid delays and have everyone stick to action points, we make sure to chase up through phone or message, but always need to communicate through email. This helps ensure that both parties stay up-to-date on a project’s status and that we have written confirmations.

  • Developing at the edge: Best practices for edge computing

    Edge computing continues to gain force as ever more companies increase their investments in edge, even if they’re only dipping their toes in with small-scale pilot deployments. Emerging use cases like Internet-of-Things (IoT), augmented reality, and virtual reality (AR/VR), robotics, and telecommunications-network functions are often cited as key drivers for companies moving computing to the edge. Traditional enterprises are also looking at edge computing to better support their remote offices, retail locations, manufacturing plants, and more. At the network edge, service providers can deploy an entirely new class of services to take advantage of their proximity to customers.

    In this article, we consider edge computing from the perspective of application developers. The developer perspective is vital because the applications being developed today—leveraging emerging technologies like artificial intelligence and machine learning (AI/ML)—reveal new opportunities to deliver services and optimize costs.

  • Fedora 33 Is Shaping Up To Be One Of Its Biggest Releases Ever

    Fedora 33 is easily shaping up to be one of the biggest releases ever for this long-time Linux distribution formerly known as Fedora Core. It's just not a few big features like Fedora desktop variants defaulting to Btrfs but even just on feature count alone it's looking by far to be one of the biggest at least in a number of years if not ever.

    Fedora 33 has seen 40 system-wide changes submitted and 18 self-contained changes. For the broad system-wide changes, at 43 it's nearly double that of usual Fedora releases with the likes of F32 seeing only 23 changes or 21 for F31. The second highest release for number of system wide changes was 31 for Fedora 28... Seeing above 40 is rather historic as outlined by this mailing list post via Zbigniew Jędrzejewski-Szmek.

Approved: Fedora 33 Desktop Variants Defaulting To Btrfs File-System

Filed under
Linux
Red Hat

The Fedora Engineering and Steering Committee formally signed off today on allowing Fedora 33 desktop variants to default to using the Btrfs file-system rather than the existing EXT4 default or other alternatives.

About a decade after the Btrfs default for Fedora was originally proposed for multiple release cycles, with the Fedora 33 release due out this autumn is when that milestone may finally be realized. Of course, if issues come up with the Btrfs usage of Fedora, the change could still be reverted, but FESCo gave the go-ahead. As stated, this default change just affects desktop variants of Fedora 33 like Fedora Workstation.

[...]

Fedora developers are still evaluating possible transparent file-system compression and other features that could get flipped on for Fedora 33.

So as it stands now desktop variants of Fedora 33 are positioned to be using Btrfs by default now that FESCo has formally granted approval but we'll see if any issues come up between now and the anticipated October F33 release.

  • GNU Emacs 27.1 Adds HarfBuzz Text Shaping, Native JSON Parsing

    GNU Emacs 27.1 is the latest feature release for this very extensible text editor. With Emacs 27.1 there is support for utilizing the HarfBuzz library for text shaping. HarfBuzz is also what's already used extensively by GNOME, KDE, Android, LibreOffice, and many other open-source applications. Emacs 27.1 also adds built-in support for arbitrary-size integers, native support for JSON parsing, better support for Cairo drawing, support for XDG conventions for init files, the lexical binding is now used by default, built-in support for tab bar and tab-line, and support for resizing/rotating images without ImageMagick, among other changes.

  • Philip Withnall: Controlling safety vs speed when writing files

    g_file_set_contents() has worked fine for many years (and will continue to do so). However, it doesn’t provide much flexibility. When writing a file out on Linux there are various ways to do it, some slower but safer — and some faster, but less safe, in the sense that if your program or the system crashes part-way through writing the file, the file might be left in an indeterminate state. It might be garbled, missing, empty, or contain only the old contents. g_file_set_contents() chose a fairly safe (but not the fastest) approach to writing out files: write the new contents to a temporary file, fsync() it, and then atomically rename() the temporary file over the top of the old file. This approach means that other processes only ever see the old file contents or the new file contents (but not the partially-written new file contents); and it means that if there’s a crash, either the old file will exist or the new file will exist. However, it doesn’t guarantee that the new file will be safely stored on disk by the time g_file_set_contents() returns. It also has fewer guarantees if the old file didn’t exist (i.e. if the file is being written out for the first time).

  • Daniel Espinosa: Training Maintainers

    Is not just help others to help you, is a matter of responsibility with Open Source Community. Your life have wonders and should change for better, so you will be lost opportunities or simple can’t work on your favorite open source project. Prepare your self to be a maintainer professor, change your mind for the beginning and help others, that is also a great contribution to open source software. Be kind. Your potential contributors will take over when required. Making sure they have the abilities and use best practices in the project, is not just good for your project, is good for all others out there; they will use them to help other projects.

  • nanotime 0.3.1: Misc Build Fixes for Yuge New Features!

    The nanotime 0.3.0 release four days ago was so exciting that we decided to do it again! Kidding aside, and fairly extensive tests notwithstanding we were bitten by a few build errors: who knew clang on macOS needed extra curlies to be happy, another manifestation of Solaris having no idea what a timezone setting “America/New_York” is, plus some extra pickyness from the SAN tests and whatnot. So Leonardo and I gave it some extra care over the weekend, uploaded it late yesterday and here we are with 0.3.1. Thanks again to CRAN for prompt processing even though they are clearly deluged shortly before their (brief) summer break.

  • Explore 10 popular open source development tools

    There is no shortage of closed-source development tools on the market, and most of them work quite well. However, developers who opt for open source tools stand to gain a number of benefits. In this piece, we'll take a quick look at the specific benefits of open source development tools, and then examine 10 of today's most popular tooling options. [...] Git is a distributed code management and version-control system, often used with web-based code management platforms like GitHub and GitLab. The integration with these platforms makes it easy for teams to contribute and collaborate, however getting the most out of Git will require some kind of third-party platform. Some claim, however, that Git support for Windows is not as robust as it is for Linux, which is potentially a turnoff for Windows-centric developers. [...] NetBeans is a Java-based IDE similar to Eclipse, and also supports development in a wide range of programming languages. However, NetBeans focuses on providing functionality out of the box, whereas Eclipse leans heavily on its plugin ecosystem to help developers set up needed features.

  • Growing Dask To Make Scaling Python Data Science Easier At Coiled

    Python is a leading choice for data science due to the immense number of libraries and frameworks readily available to support it, but it is still difficult to scale. Dask is a framework designed to transparently run your data analysis across multiple CPU cores and multiple servers. Using Dask lifts a limitation for scaling your analytical workloads, but brings with it the complexity of server administration, deployment, and security. In this episode Matthew Rocklin and Hugo Bowne-Anderson discuss their recently formed company Coiled and how they are working to make use and maintenance of Dask in production. The share the goals for the business, their approach to building a profitable company based on open source, and the difficulties they face while growing a new team during a global pandemic.
