Emily Freeman (author of DevOps for Dummies and Principal – DevOps Solutions at AWS)

Drafting Success

Writing a book is the hardest achievement I’ve set out to accomplish. I finished it like a marathoner at the end of a long race, crawling toward the finish line. I was empty. But finishing the book isn’t the interesting story. The journey is where I learned the valuable lessons. Only in the tears and the toil, in the mud of my own emotions and self-doubt, did I learn the truths of struggle, resiliency and creative work.
Engineering software is creative work. Yes, we talk about algorithms and lambdas. But our work transcends science and technology. I believe we need to rethink the definition of success, learn to write the first draft and work as a community to better technology. It’s the lessons I learned in the trenches of my own creative work that I think we can apply to our DevOps organizations.

Speaker Bio: Emily is the author of DevOps for Dummies and Principal – DevOps Solutions at AWS. Her experience spans both cutting-edge startups and some of the largest technology providers in the world.

Emily is best known for her creative approach to identifying and solving the human challenges of software engineering. It is rare in the technology industry to find individuals equally adept with code and words, but her career has been defined by precisely that combination.

Emily is a technologist and a storyteller who helps engineering teams improve their velocity. She believes the biggest challenges facing developers aren’t technical, but human. Her mission in life is to transform technology organizations by creating company cultures in which diverse, collaborative teams can thrive.

MacOS: A Quests to Find Vulnerability Land

This info moment will expose the difficulty that Security Engineers, System Admins, and users, in general, have while trying to find information about Vulnerabilities and remediations for MacOS. Mac disclosure of vulnerabilities is hard to find making the investigation process for patching difficult and lengthy. For example, there is an existing issue for 10 years (CVE-2021-3156) but there is no accurate way to check for documentation since this is the first time that is being documented for Mac OS systems but not through Apple’s official site. We will compare the way Microsoft presents their vulnerabilities with details but Apple doesn’t have a one-stop site link where this information is displayed. In some cases, users have to ask Apple directly for vulnerability information rather than having a one-stop-shop site. Users need to go to multiple sources to find bits and pieces of information to confirm if a given MacOS vulnerability was resolved. Mac should implement a way to allow their users to find in one-stop accurate information about vulnerabilities, product affected, and resolution times.


Speaker Bio: Estela Baca is Cybersecurity Technical Account Manager who enjoys exploring new software technologies, development tools, the latest technology trends, etc. In her free time, she enjoys reading Cybersecurity white paper reports and listening to the Black Hills podcasts to be up to date with the latest Information Security news. She is also passionate about reading biographies of world leaders to try to understand socio-cultural views that helped shaped today’s society.

What I Should Have Thought About Before Archiving 263TB to the Cloud

Let’s chat about the process of moving hundreds of terabytes of data to the cloud as a preventative measure to keep the data safe during the physical move of a storage array. What is normally a no-brainer with tens of terabytes becomes a different animal with hundreds of terabytes. One client, one consultant and two vendors collaborate to make this happen. It was not without its trials and terror and it taught me to ask questions that I didn’t know to ask before. Now I want to share.


Speaker Bio: I’m a speaker, author and most importantly, trusted resource to my clients. I’ve been around the Apple as a user world since the beginning of the company and for over 20 years as an IT professional. I truly enjoy my clients, their creativity and the magic they bring to the world. I am lucky to be able to help them achieve their goals.

Aspen Lindblom (CrowdStrike)

30 Minute Talk

Shlaying the beast: A playbook for the most pervasive adware on MacOS

Shlayer made its debut back in 2018 and it is still the most common malware infection on macOS. It uses social engineering to trick users into installing and assisting in bypassing Apple’s built-in security features, quickly establishes persistence and immediately installs more adware friends. This talk will go over how Shlayer operates and how to defend against it.
Speaker Bio: Aspen Lindblom is a Threat Analyst at CrowdStrike where she focuses on improving detection capability and efficacy through researching and analyzing malware. Prior to that she was in IT for 8 years before switching to cyber security.

5 minute quick talk

Mama Don’t Take My ARD Away

When all the computers were at the office Apple Remote Desktop was the one tool to rule them all. But now that everyone has dispersed to the four winds to Work from Home, other tools may not offer the same versatility for remote controllers in sticky situations that require control of login screens, AppleSetup Dialogs, and Migration Assistant runs. Setting up a BlueSky server in Docker can be an inexpensive and fruitful way to use Apple ScreenSharing with remote users who need you to shepherd them through things like Migrations.

Speaker Bio: Alex is a past presenter at MDO and an Apple Certified IT Consultant at Precursor Systems.

Piero Mamberti (GoCardless)

Kanban is your friend or: how I got to love boards (yes, the jira ones too)

How does talking about Toyota end up in a MacDevOps conference? What is Kanban? Can it really make your life better? Let’s go for a quick  history of Kanban, its principles, and explore how it can help you deliver faster and higher quality work.

Speaker Bio: Piero is working as a Technical Lead in the IT Engineering team at GoCardless. There, he enjoys building things, refining processes and helping others. He’s been mostly focused on macOS and the opensource world that revolves around managing it, but since stumbling upon the DevOps philosophy, he discovered a keen interest in flow and how to optimise it, he’s kind of a kanban fanboy since then. In his free time, he eats, walks, reads, climbs and learn to code with various degrees of success.

Joel Rennich (Jamf)
