DevOps: A Software Architect’s Perspective

The First Complete Guide to DevOps for Software Architects

DevOps promises to accelerate the release of new software features and improve monitoring of systems in production, but its crucial implications for software architects and architecture are often ignored.

In DevOps: A Software Architect’s Perspective, three leading architects address these issues head-on. The authors review decisions software architects must make in order to achieve DevOps’ goals and clarify how other DevOps participants are likely to impact the architect’s work. They also provide the organizational, technical, and operational context needed to deploy DevOps more efficiently, and review DevOps’ impact on each development phase. The authors address cross-cutting concerns that link multiple functions, offering practical insights into compliance, performance, reliability, repeatability, and security.

genius-tabletdiscussions: Members talked about Spokane Linux Fest — and we’re looking forward to the next one. Mining Bitcoins, Virtualbox, and Ubuntu’s native support of Genuis tablets.

recommended program: NOVA: Rise of the Hackers.

April 2015

Our members recommend: Use ‘sudoedit‘ instead of ‘sudo‘ to edit config files.
Set up Bash to record all commands into a log file because History can disappear a bunch of different ways. Handy to be able to log everything you do.
Segment on 60-minutes about online tracking:
Browser add-ons recommended: Ghostery, NoScript, and AdBlock Plus
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

PostgreSQL is a powerful, open source object-relational database system.

Tip of the day: persuade everyone to do hard-core backups of everything — ‘crypto-lock’ viruses are getting very bad. These viruses have been seen to mutate in real-time in response to online forums talking about them.

our members recommend: In the Beginning was the Command Line, by Neal Stephenson, 1999:

the Debian Administrator’s Handbook:

on the new venue front: Ben visits the new David’s Pizza location in the Arena / Flour Mill area (803 N Post Street). It looks like a great place for pizza, but holding a meeting here could be a challenge: Our much-used round table is placed up in a loft area that has no wall space for presentations. Music / noise levels may interfere. An unfinished south section remains to be investigated for future private parties. It’s great to see David’s Pizza open again … and everyone should visit for some of Spokane’s best pizza. Nice photos of the new space:

possible presentations dept: There are no planned presentations for April, but rumors are circulating about weather stations and email servers / spam protection.


February 18, 2015

Discussion Topics:

220px-Hedy_Lamarr-publicityHedy Lamarr and her contributions to spread spectrum and frequency hopping communications.

GitLab: a replacement for GitHub that you can host on your own server and has more features.

Plex Media Server and the importance of naming your movies correctly.


Richard and Grant will be representing us at: LinuxFest 2015 at SFCC on Saturday May 9th from 9am to 4pm. More info at

Possible presentations for March: weather stations and using Simple Scan. Hope to see you in March.


The Official Ubuntu Book, Eighth Edition

The free Ubuntu operating system has won the hearts and minds of millions of users worldwide. It combines a strong technical platform, impressive quality, and an enthusiastic global community of users who relentlessly support, document, and test it.

The Official Ubuntu Book, Eighth Edition, has been extensively updated with a single goal: to make running today’s Ubuntu even more pleasant and productive for you. It’s the ideal one-stop knowledge source for Ubuntu novices, those upgrading from older versions or other Linux distributions, and anyone moving toward power-user status.

Richard presented some Bash scripting examples he uses for Vagrant-managed virtual machines; for setting up SSH sessions, monitoring the connections, and shutting down all connections when any one port breaks.

Thought of the day from Larry Wall: “The three chief virtues of a programmer are: Laziness, Impatience and Hubris.”


The Design and Implementation of the FreeBSD Operating System (2nd Edition)

The most complete, authoritative technical guide to the FreeBSD kernel’s internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition’s content is completely new, and another one-third has been extensively rewritten.

Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel’s current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down–from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking.

Converting a PNG graphic file to PDF

One way is to install the ‘imagemagick’ package on your system (sudo apt-get install imagemagick), then use this at the command line:
convert sample.png sample.pdf
Multiple PDF files can be combined into a single, multi-page PDF with several different programs — my favorite GUI PDF page-manipulation program is ‘PDF Mod’, which allows you to add, delete, re-arrange, and rotate pages in PDF documents.

Members are testing out:

the ‘Plex’ media server — “it’s like having your own personal Netflix”; Debian Stable w/ Gnome 3 desktop; Clam AV for scanning for viruses on a server that hosts files for Windows computers; Linux Fest Northwest in May at SFCC; Chrome OS nice alternative for simple computing needs in virus-free environment; and CrashPlan for online back-ups.
Backing up your data 3-2-1 rule: always keep THREE copies of your data, on at least TWO different types of media, and at ONE different physical location.


Joe did a short presentation about effective Google searches: type in exact error codes; read every link on the first page because many entries below refer to and correct entries above, for stronger focus use the term twice in the same search, use ‘site:’ to search on a specific web site, use the minus sign to exclude a term or site from your search, include terms relevent to search but not general terms — known as “TFIDF”: Term Frequency Inverse Document Frenquency, quotes can pair seperate words into a single term, capital ‘OR’ will include both topics in a search.
