A Tour of Open Source on the Mainframe

All Things Open

Presented by: Elizabeth Joseph, IBM Presented at All Things Open 2020 Abstract: Many enterprises and, as many of us learned during the COVID-19 outbreak, governments, rely on mainframes to do the bulk of their data-driven work and the modern mainframe is very good at what it does. But what if you’re looking to modernize your platform and bring in the DevOps methodologies, tooling, and practice into your organization? Today, there is an entire product line of mainframes that exclusively run Linux (RHEL, SLES, or Ubuntu). With Linux, you get access to the vast ecosystem of open source software that’s already been ported to the mainframe architecture (s390x), with more being ported every month. If your organization is using z/OS, the Open Mainframe Project has a series of open source projects targeted specifically at the mainframe and improving usability. Zowe, for instance, helps create a consolidated API for accessing resources and workload on your system and Feilong is a z/VM connector that allows you to manage your virtual machines with familiar open source tooling like OpenStack. There are even connectors for Jenkins that allow you to integrate CI/CD pipelines with your workloads. In this talk I’ll explore all of this in more to show you how an automated, modern environment can thrive on today’s mainframe.

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...

James Anderson

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Torvalds to kernel devs: grow up and stop pulling all nighters just before deadline (https://www.theregister.com/2022/10/17/linux_6_1_rc1/) "Let me just say that after I got my machine sorted out and caught up with the merge window, I was somewhat frustrated with various late pull requests. I've mentioned this before, but it's _really_ quite annoying to get quite a few pull requests in the last few days of the merge window.""Yes, the merge window is two weeks, but that's very much to allow me time to look things over, not 'two weeks to hurriedly put together a branch that you send Linus on Friday of the second week'," he wrote. "The whole 'do an all-nighter to get the paper in the day before the deadline' is something that should have gone out the window after high school. Not for kernel development." Linus had faulty memory (ram) slowed kernel development https://www.theregister.com/2022/10/10/linus_torvalds_ecc_memory_fail/
