      I just published my first book, The Virtual Disk Guide

      Written by Tim Bielawa

      I’m very excited (and proud) to announce that on March 3rd, 2016 I reached a long-term goal I set for myself 3½ years ago, by self-publishing my first book, The Linux Sysadmin’s Guide to Virtual Disks. The book is published under my new brand, Scribe’s Guides.

      The first edition of The Virtual Disk Guide has been a long time coming. Nearly 7 years of on-and-off writing have gone into it. I’m relieved to have made it this far.

      About the Virtual Disk Guide

      I view the book as the definitive reference guide for virtual disk related activities — clear, concise, accurate, and approachable to readers of all skill levels— but that’s just my opinion. You can decide that for yourself.

      The book is quite thoroughly cited and annotated with nearly 100 individual footnotes and references to additional learning resources. The book weighs in at around 80 pages, 7 chapters, and two technical appendices. Here’s the byline from the scribesguides.com website:

      The Linux Sysadmin’s Guide to Virtual Disks demonstrates the core concepts of virtual disk management. Real-world problems are covered in the book’s “Cookbook” section. Other topics include: helper utilities, disk formats, troubleshooting tips, performance considerations, and comprehensive appendices.

      Get Buy one (please?)

      • Buy a hard copy of the first edition for $10.00
      • Read the latest build[1] of the PDF or HTML versions online for free

      Or do both! Say “thanks!” by purchasing a copy, and then enjoy the latest builds online forever, for free!

      [1] – The original first edition text is also available for free in PDF and HTML formats and is identical to the print copy

      Open Source

      More Blog Posts Coming Soon

      The experience of writing and publishing this book has taught me much, and it’s time to spread that information. Check back soon for a follow-up post I’m writing which covers more of the technical side of self-publishing. Specifically, self-publishing a DocBook 5 document at the on-demand printing website lulu.com.

      Let me be explicitly clear, this is not a promotion for lulu.com.

      Rather, the post will review some of the technical challenges I encountered (old examples: #1, #2, #3) during the publishing process, including challenges specific to Lulu. Such as, how I customized the PDF output from dblatex to look more personal and less generically academic, why I had to order three proof copies of the book before the cover matter printed in decent quality, and how to adjust your inner and outer page margins so there’s a reasonable amount of whitespace between the spine/binding and the body text.

      I have a feeling that by the time I’m done with the blog posts I’m going to have written another book of documentation about how I wrote a book of documentation

      Bootstrapping a DevOps Movement in Red Hat IT – Video

      Written by Tim Bielawa

      Back in late 2013 I joined what was jokingly referred to as the Red Hat IT “DevOps” team. We didn’t like that name, so we changed it and there-after became officially known as Team Inception. From the time the team was formed, we all accepted that the team was to retire in 18-24 months. We were totally cool with that too! To us having a pure “DevOps” team in perpetuity just didn’t make sense.

      Over the course of the team’s lifespan I feel like I experienced incredible growth, both personally and professionally. I’m proud to look back at all the cool things we accomplished as a team, and I’m even more thankful to have had the opportunity to be a member of that team. Here’s a taste of some things we did as a team publicly:

      • Blogged a bunch of posts for Red Hat Developer Blog
      • Created a functioning Continuous Deployment system, Release Engine [Docs]
      • Created jsonstats, a tool for exporting system information over a REST interface
      • And another tool, Talook, which provides a view into jsonstats running on a collection of servers
      • Cacophony, a simple REST API for automatic SSL certificate generation
      • The Ansible XML module. This grew in popularity so much that we realized the best way to ensure it lives on was by transferring complete ownership over to Chris Prescott, a former contributor (Thanks Chris)!

      Two week ago (2015-06-20 → 2015-06-24) the DevNation and Red Hat Summit 2015 conferences were held in Boston, MA. Of the many excellent speakers and panel groups [S|D] that held sessions during the conferences, there’s one group I am especially fond of: My old team, Inception.

      On Wednesday, July 24th we held a panel session called Bootstrapping a DevOps Movement in Red Hat IT. This was our final activity together as Team Inception. During this panel-style session Jen Krieger, our Product Owner/Scrum Master, facilitated a look back at some of our experiences during our 18 months as the Red Hat IT “DevOp Team”.

      We began the initial round of questions with what our individual perceptions of “DevOps” were before the team had formed. We followed that with what ended up being a great Q&A with the audience (thank you everyone who participated!). We ended the panel with our closing thoughts on what “DevOps” means to each of us now.

      Here’s a snippet from the official session description:

      Topics will include

      • What we accomplished. We’ll take you step-by-step through how we deliver our work using a combination of open source tools, including Docker.
      • How we rate both our cultural and tooling success.
      • Roadblocks, disruptions, and surprises we encountered and how we handled them.
      • How this project has changed the way we view our jobs and our work relationships.
      • What’s next for the team.

      Panel

      • Tim Bielawa, Release Engineering / Development
      • Ryan Cook, System Administration
      • Steve Milner [blog], Security / Development
      • Chris Murphy, System Administration

      Panel facilitator

      • Jen Krieger [pinterest], Agile Coach & Original Inception Product Owner

      Between ourselves, we casually referred to this as our final team retrospective, an honest (and very public) look-back at lessons learned over the last year and a half.

      And before I forget. So much thanks to Andrew “Hoss” Butcher [GH] for recording, editing, and posting the recording for us. I (we) owe you many Tasty Beverages for that.
