Developer eXperience (DX) is crucial for the success of an API. That is why API teams build developer portals where the team can publish their API reference. This is where most teams fail. A great developer experience requires more than reference docs. In this talk Kristof Van Tomme will describe the upstream and downstream developer journey, and introduce the different documentation components you need to create a great DX.

About Kristof

Kristof is the CEO/co-founder of Pronovix, a consultancy specializing in developer portals, documentation systems, and API integrations - built in Drupal. He lives in Belgium, but runs a Write The Docs meetup and an API meetup in London. Last year his consultancy (Pronovix) customized 20+ developer portals, implementing design changes, access control, search, and other features that ambitious developer portals require. In this session he will share what he has learned.

Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Abstract: From late March 2015 through April 2016, long-time PLUG member Russell Senior had a job at the Center for Coastal Margin Observation and Prediction (CMOP), where he learned about Ocean Gliders, got to war sail on a Research Cruise along the Oregon Coast, and learned about many of the instruments used in monitoring the biogeochemical properties of estuarine waters. He will relate some or many of those things, consistent with what he can manage to remember, or possibly invent on the fly. This could be stretched into a multi-part talk, so if the prospect of listening to him for extended periods is painful to you, consider it an inducement to come up with your own much better talk!

Web developers who only know about GET and POST and use the most popular headers and response codes are missing out! Underappreciated verbs, headers, and response codes can boost your web application's performance, flexibility, and testability, and help you better appreciate the structure of the web.

The version of the Hypertext Transfer Protocol you will deal with most is 1.1. As a quick refresher: Clients and servers talk to each other via HTTP messages (requests and responses), which are clear text comprising start-lines, headers, and bodies.

METHODS

GET ("gimme") and POST ("here you go") are overwhelmingly popular, the Dave Matthews Band of methods. To illustrate their importance: you can create an API that allows the user to POST but not GET, but that would be a terrible idea. https://github.com/brainwane/secureapi demonstrates this with Python 2 code using the BaseHTTPServer standard library.

Using POST to mean "Create resource", "Update resource", and "Delete resource" is inelegant! So why do we overload POST, and what are the alternatives? PUT, meaning "create resource," is implemented throughout the HTTP 1.1 ecology and is unambiguously great; be more careful with DELETE, which deletes a resource (as demonstrated with Python 2 code using the BaseHTTPServer standard library and the requests library). It's also worth looking into PATCH and OPTIONS for specialized use cases.

An exciting alternative to GET is HEAD, which requests only the metadata about a resource; if the client really only needs to know whether it could GET a resource, or wants a resource's size, last-modified timestamp, or other information available in its headers, using HEAD instead of GET can speed performance by more than 50%. I demonstrate this using the requests library and the %timeit functionality in IPython.

Also, why am I both discussing good and bad ideas throughout this talk, and how can you tell the difference? Sometimes bad ideas are easy ways to understand edge cases (also, they're funny). The "horror world-to-whiteboard scale" gives you my take on whether or not you should try out what I'm describing.

HEADERS

Call-and-response header pairs such as Last-Modified and If-Modified-Since/If-Unmodified-Since allow the client to conditionally specify its preferences; you can save client-side processing time, and test your application more thoroughly, by knowing and using the right headers. For instance, check for cache problems by using Cache-Control and ETag. (But not all headers are useful; for instance, the From header is basically obsoleted by more advanced analytics and by the User-Agent header.)

We require that clients send a Host header with all requests; Host works with the path specified in the start-line, the two together forming the full address of the resource. Sometimes the host is merely the domain name of the server, but you can't depend on the assumption that the host will be obvious to all the systems between the client and the server. The client might send a request to an IP address, or to one of several virtual hosts that act as subdomains on one host. This level of redundancy can lead to unintended consequences; for instance, by intentionally malforming the Host headers of GET requests, spammers can leave links to their own sites in your access logs.

You can define your own header when sending requests or responses, and many organizations do this; the convention is to prepend "X-" to bespoke headers. It's easy to do this when hand-writing requests, and I'll also demonstrate how to do this in a Python web framework.

RESPONSE CODES

Response codes (a.k.a. status codes) have well-specified semantics. For instance, they come in five numbered classes, and the three-digit integer should be sufficient to explain the response -- the "reason-phrase" (the English explanation) should not be a necessary data point for the client to use when debugging. As several responses sent by real, working web servers demonstrate, if you don't respect this principle, the results can be hilariously confusing.

HTTP includes useful response codes that mean more specific things than "OK" or "nope"; 410 Gone, 304 Not Modified, and 451 Unavailable for Legal Reasons help you and your users move faster, debug, test, and recover from unavailable content.

I demonstrate how to alter the reason-phrases in your web application's response codes, using the http standard library in Python 3: https://gitlab.com/brainwane/http-can-do-that/

From "don't cache this" instructions to look-before-you-leap requests to using the "Content-Disposition" header to tell clients that a resource should be treated as an attachment, HTTP already contains an embarrassment of riches. Reading up on it gives you both a feeling of power, of increased capability, and a sense of wonder, in discovering a new way to look at the world. What might the web have been? What might it still be?

Rust is meant to compete with C and C++ in performance, but also provide memory safety. Someone has written a small kernel in Rust.

Rust is only attractive to JavaScript / Python types when they run into a problem where memory consumption or processor consumption is a real limiting factor. Then, it's much easier for them to transition into Rust than C/C++, but Rust gives them the performance they need.

Some Rust killer apps:

• Mozilla's experimental browser engine, Servo (which outperforms Firefox on a single core, and destroys it when running on four cores);

• Tilde's Skylight profiling system for Rails apps, which uses Rust to handle the voluminous data produced by running apps: http://www.tilde.io/skylight/

• OpenDNS, which is again using Rust to handle large amounts of data in real time:

https://labs.opendns.com/2013/10/04/zeromq-helping-us-block-malicious-domains/

Added focus: Concurrency first in Rust

Multiprocessor machines are everywhere: even mid-range mobile devices now often have more than one processor core. But writing concurrent code in C and C++ is challenging even for experienced developers: data races are notoriously difficult to debug, and concurrency makes ordinary memory bugs harder to reproduce. So programmers usually turn to concurrency as a last resort, only after they’ve squeezed as much performance out of their single-threaded code as possible.

But what if concurrency were practical as a method of “first resort?” What if we could design ordinary programs around the opportunities for parallelism they present, without introducing risk and making our code hard to maintain for all but the wizards?

Rust is a new systems programming language from Mozilla, designed for memory safety and trustworthy concurrency. Rust catches data races and memory errors at compile time: you can’t forget to lock the right mutex before accessing shared data, nor can you modify a data structure after handing it off to another thread, nor can you free data that another thread was using, and so on. Rust does not use garbage collection, but instead relies on a simple set of rules for ownership, moving, and borrowing to prevent the kinds of memory errors that plague concurrent C and C++ code. Mozilla has used Rust to implement an experimental browser engine named Servo, which already outperforms Firefox’s Gecko engine on real-world web sites.

This talk will demonstrate various styles of concurrent code in Rust: message passing, shared data protected by mutexes, and lock-free algorithms using atomic memory operations. We’ll show how Rust’s ownership rules, unique among production programming languages, prevent data races. And we’ll show how to take responsibility for correctness yourself when the compiler is too strict, using Rust’s ‘unsafe’ mode.

Distributed systems have gone mainstream and are redefining the way we think about building and deploying applications. The container represents a modern abstraction for applications and provides the necessary constraints for building robust and self-aware systems on top of the core tenants of distributed computing.

In the future the virtual machine will disappear and a logical computer will emerge that stretches across the datacenter and plugs into the global network over high speed links. Some will say this future is more than a decade away, but what if I told you it exists today and it's source code was available on GitHub?

In this talk we will take a look at Kubernetes, the open source container management platform, and how it's changing the way we think about compute.

The world of software development rightly demands an emphasis on the new and the innovative -- on doing things differently from how they’ve been done. The assumption is that newer is (almost) always better. But if we look only to the present and the future, we risk reinventing the wheel, failing to understand that we are all built on tradition, failing to learn everything that we could from the past.

This talk shows how documentarians can find inspiration in the past, build on it, and move forward. It tells some of these stories, and shows what they meant in historical context:

• The pre-history and dawn of software documentation -- how technical writers were hired, how they worked, what they made, the challenges they faced, and how their solutions continue to inform the work we do today

• The much longer history of teaching engineers to write documentation

• Efforts to make technical writing into an independent profession

Portland Linux/Unix Group: Block Storage Device Life Cycles

Block storage has joined electricity as one of the fundamental technologies on which we are completely and irrevocably dependent. The two technologies are in fact becoming inextricable now that computers control virtually every electrical system from the distribution grids on up, and computers themselves are completely dependent on electricity to operate. Both technologies have undergone countless innovations yet still operate largely on their original basic principles. While high in capacity, fast and affordable, the modern hardware block storage device or “hard disk” operates on the same principles as the original 1956 IBM 350 disk storage unit and most solid-state alternatives emulate hard disks. Beginning with the Berkeley Fast File System, the BSD family of operating systems has played a key role in the evolution of general purpose block storage and continues this innovation with technologies like virtual block storage devices, GEOM, UFS2, ZFS, GELI, HAST, GEOM Journaling, FUSE, tmpfs and the NAND Flash framework. This paper will survey the available block device options in the FreeBSD operating system and explore their practical uses in modern storage architectures.

FreeBSD is unique in that it provides the reference platform for the Unix File System and is now a tier one Zettabyte File System or ZFS platform. The 10.0 release of FreeBSD is particularly unique in that it includes in-kernel iSCSI network block device sharing, the NAND Flash framework, a FUSE implementation and the bhyve hypervisor which can leverage and help test most FreeBSD storage technologies. The FreeBSD ports collection also includes support for guest file systems such as ext2 and NTFS, which provide new opportunities to "round trip" virtual and physical machines using bhyve and tools such as the iBFT iSCSI boot framework.

Finally, while an unprecedented block storage toolkit can enable extensive experimentation, there are pragmatic issues surrounding production storage architectures. This paper will touch on real world block storage solutions built with FreeBSD and its derivatives. These derivatives include the FreeNAS storage appliance, which provides networked block and file storage to a myriad of Unix and non-Unix clients. Pragmatic issues surrounding verifiable data integrity include: understanding and embracing ZFS behavior and limits, observing disk and partition health in addition to data integrity, understanding the implications of file naming, maintaining backups and restoring desired data in a timely manner.

Copyleft licenses, particularly the GPL and LGPL, are widely used throughout the Free Software community. However, recent for-profit corporate interest in Free Software development has led to a renewed preference toward non-copyleft licensing by for-profit entities. Meanwhile, many for-profit entities that do use copyleft for their own software now do so in a manner that most copyleft aficionados find, at best, distasteful and at worst, abusive.

A long-standing truce exists in our community between fans of non-copyleft licensing and copyleft. No one in the copyleft communities disputes that non-copylefted Free Software is an important part of our community. However, copyleft faces new challenges that make past debates about the appropriateness of copyleft seem quite minor by comparison.

This talk will discuss all aspects of the complicated situation facing copyleft, including younger developers apparent preference for non-copyleft licensing (as expressed, in part, in the "post-open source" debates), the widespread and common failures for companies to comply with GPL's relatively easy requirements, and how licensing choices are today, unlike in the past, rarely in the hands of individual developers, but instead their corporate employers.

Bradley M. Kuhn is the President and Distinguished Technologist at Software Freedom Conservancy (sfconservancy.org) and on the Board of Directors of the Free Software Foundation (FSF). Kuhn began his work in the software freedom movement as a volunteer in 1992, when he became an early adopter of the GNU/Linux operating system, and began contributing to various FLOSS projects. He worked during the 1990s as a system administrator and software developer for various companies, and taught AP Computer Science at Walnut Hills High School in Cincinnati. Kuhn's non-profit career began in 2000, when he was hired by the FSF. As FSF's Executive Director from 2001–2005, Kuhn led FSF's GPL enforcement, launched its Associate Member program, and invented the Affero GPL. From 2005-2010, Kuhn worked as the Policy Analyst and Technology Director of the Software Freedom Law Center. Kuhn was the primary volunteer for Conservancy from 2006–2010, and has been a full-time staffer since early 2011. Kuhn holds a summa cum laude B.S. in Computer Science from Loyola University in Maryland, and an M.S. in Computer Science from the University of Cincinnati. Kuhn's Master's thesis discussed methods for dynamic interoperability of FLOSS programming languages. Kuhn received the O'Reilly Open Source Award in 2012, in recognition for his lifelong policy work on copyleft licensing.

Home gun building brings interesting legal and technical challenges needed to keep someone both safe and on the right side of the law. This requires an individual to be both an amateur metalsmith as well as knowing the ins and outs of firearms and international patent law. This talk will discuss the building of the semi-automatic AK47 rifle from a technical perspective, from demilling parts kits to the construction of a fully functional semi-automatic weapon.

We will also discuss the origins of the AK design, the history of it’s variants and its current patent status as a public domain firearm design, delving into Soviet and Russian Federation patent law as well as US firearms law.

There are countless available text editors, programming languages and Integrated Development Environments (IDEs) but few are guaranteed to be present on any given system. On POSIX Unix systems, the vi(1) text editor and sh(1) shell are required by the POSIX (opengroup.org) standard and might be the only development tools at your disposal. While some developers may consider these tools equivalent to a doughnut spare tire that should not be used over 50MPH, others embrace them and have used them for decades. Some would also argue that you should learn the rules before you break them in order to appreciate higher-level languages.

This talk will be a crash course in vi(1) and sh(1) with examples from a 2500 line virtualization management project that uses a number of scripting techniques.

We will look at the security provided by OpenSSH and how the environment it is used in affects it's security. When can SSH security improve network security and when can't it.

This presentation assumes you have a basic understanding of SSH and how it is setup. Those topics will be reviewed very rapidly as we dig deeper into the security aspects of SSH. The discussion concentrates on SSH authentication using asymetric or public key encryption.

SSH is widely used to provide convenient and secure access to multiple machines on a local network, and to tunnel into remote networks to access machines on those networks that aren't directly visible to your local machine. We will analyze various use scenario's of SSH in these two usage scenario's and also the advantages and disadvantages of using an agent to facilitate SSH connections. For each of these scenario's, we will discuss the privacy aspects of one's passphrase and private keys, how secure the transmitted data is, and the ability of others to 'borrow' your credentials.

You should walk away from this presentation with a better understanding of what actions you need to take to maximize your privacy, while reaping the benefits of using SSH.

Brian and Michael are back to teach you everything you ever wanted to know about speaking at an open source from PLUG (hint hint) to OSCON.

Brian has years as an experienced Distinguished Toastmaster (beer available at the Lucky Lab NW after the meeting) and Michael has just submitted his paper for the upcoming AsiaBSDCon conference on a topic he had previously known nothing about.

Why should you give a talk?

• You are guaranteed to have a unique topic, experience and perspective
• Audiences are far kinder than you expect (only pros get boo'd!)
• Visuals are always optional and are flexible in format
• No one was born a public speaker, it's simply a learned skill
• There are great resources out there to help you
• Most things that go wrong have nothing to do with you (Tsunamis!)
• Live demos are... risky, but useful
• The LFNW and other CFP's close shortly (hint hint)

Highlight from our Advanced Topics talk: (paraphrased) "My mom got more value out of learning to community with Toastmasters than two years of a (VERY impressive school) scholarship."

YOU may change careers a dozen times in your life and need a new skill set for each job but will ALWAYS need to express yourself and communicate on behalf of yourself and your team. Let PLUG be that first step in what could be worth more than a (VERY impressive school) scholarship!

Brian says:

In 2007 I made the switch from being a machinist to a real estate agent, shortly thereafter I was invited to investigate a Toastmasters club, in order to become a better communicator. Through 5 years and over 40 speeches in Toastmasters I reached the highest level of Distinguished Toastmaster. Simply stepping out of my comfort zone has given me the opportunity introduce dignitaries, and MC fund-raising events for worthwhile causes (notably a record breaking Clark County Republican Party Lincoln Day Dinner auction). Currently I am a recognized top 2% leader in AdvoCare International, helping others achieve their physical and financial goals.

I enjoy using Linux on a personal level for the freedom that it represents.

Michael says:

Never in a 1,000 years will I speak in public yet I find myself doing it several times a month in Portland and at conferences around the world. I guarantee I'm no Brian Rohan but I fill rooms and get applause. The secret is finding the right room and just doing it. I will talk about the absolute worst that can happen (rarely what you think it would be), the open source conference community and how to get from submitting a proposal to stepping down from the stage.

Brian Martin will talk about his early experiences with Samba 4

Samba provides open-source support for the Microsoft file sharing protocol. Version 4 of Samba was released late last year. It represented years of work and a major, some would say massive upgrade to Samba to include the ability to be a fully functional Active Directory server. Given the large scale changes, many people have been avoiding production Samba 4 use while waiting for the bugs to be worked out. Brian Martin has now started migrating production environments to Samba 4 and will discuss his early experiences.

Bio: Brian Martin is the chief consultant for Martin Consulting Services, Inc. Martin Consulting has provided system administration services in Unix, Linux and Windows systems in the Portland metro area and across the country since 1996. Brian is a frequent attendee at PLUG.

Ever wondered what makes a student successful in landing that career after university life ends? Ever wanted to find that competitive edge that makes you stand out from the crowd? If you answered yes to either of the above questions, this tech talk is for you.

Frank Goovaerts is the Interim Director of Student Success at Portland State University at MCECS, and will be giving a tech talk on how to get that extra edge and what services he offers to help students transition from college to career.

If you haven't already signed up for the Hack tomorrow at PSU, we hope some details included here will entice you. To prepare our participants for a fun and productive day, below are details and resources for the Hack.

Goals: To generate ideas are innovative to solving environmental and sustainability, social equity issues through utilization of software and mobile apps. Don’t forget to have some fun.

Idea Generation: To start, you should ask the following questions: 1) What issues you and your team would like to tackle? (ie. carbon emissions reduction by buildings or vehicles, solar potential identifier, change of personal habits, e-waste tracking, etc.) 2) What do other similar applications exist on the market? Sometimes, building on existing apps can resolve a more refined product. 3) What is the marketability? Is it scalable?

The best project ideas are one that you are passionate about, and have some components of competition and linkage to social media.

Finding Data: While you are brainstorming ideas, you should also consider data availability as well. It is not the end of the world if you don’t have data sets or APIs to mock up a prototype. Simply build your own datasets, even if just a few that are enough for you to test out your product.

See the Cleanweb Hack resource guide for APIs, data sets, sample projects and project ideas. (http://tinyurl.com/m7a744e)

Judging Criteria: At the end of day, your prototype will be scored on these criteria: 1) Impact on resource and sustainability issues 2) Design and usability of prototype 3) Feasibility and marketability 4) Good use of datasets and APIs

Prizes: 1st Place - $500, 2nd Place - $250

Bragging right is priceless.

Our judges are looking forward to your innovations!

Hacking on the new Beagle Bone Black

Description:

Russell recently spent some time working on porting a house-monitoring system from the Beagle Bone (an $89 embedded, ARM-based, I/O rich device running linux http://beagleboard.org/) to the new Beagle Bone Black, a $45 device which is faster, includes video and 2G of onboard flash. The sensors required a one-wire bus, one of which the original Beagle Bone had configured out of the box. The Beagle Bone Black had none. This talk is a description of what it took to get one-wire (specifically w1-gpio) going with his own custom "cape" (a daughter-board for the Beagle Bone).

Biography:

Russell Senior has been a GNU/Linux user for over 20 years, since the 0.99plN days, using it both recreationally and professionally as a research programmer/scientific data analyst. Since 2005, Russell has become involved as a principal volunteer with the Personal Telco Project (https://personaltelco.net), during which he has worked on embedded systems, primarily network routers. He contributes to the development and improvement of the OpenWrt project. In the last couple years, he has worked on monitoring systems involving Arduino and, since last year, the Beagle Bone and has learned a bit about the Angstrom distribution of linux for embedded devices.

Mozilla Socorro: an Open Source crash reporting system evolves.

Socorro collects and analyzes three million crash reports a day employing PostgreSQL, HBase, Hadoop, and ElasticSearch glued together with Python. Socorro's data analysis drives the stability and development priorities of Firefox. Five years ago, Socorro was a system that ran on three machines and was tended by just one person. In 2013, it has evolved to become a distributed system running on 120 machines and serving hundreds of terabytes of data. Meanwhile, companies all over the world are adopting Socorro for crash reporting. This talk, an update of one given several years ago, will track the evolution of Socorro and its future in the upcoming world of FirefoxOS.

K Lars Lohn is the Herd Patriarch of the Mozilla WebTools Group. As the author and curator of the Mozilla Socorro Crash Reporting System, Lars has driven its evolution. Formerly with the OSUOSL, Lars telecommutes for Mozilla from a farm near Corvallis. While preferring Python, PostgreSQL and Harleys, Lars is versed in C++, MySQL and Subarus.

Historically, implementation of electronic health records in medical offices have been problematic. Specifically, poor implementation of these products is the leading cause of failure of acceptance of EHRs in these offices. Implementation of EHRs in the small physician office remains poorly documented and this contributes to this failure rate. To address this need, OEMR (The OpenEMR Non-Profit) developed an internship experience with the Department of Medical Informatics and Clinical Epidemiology at Oregon Health and Science University to develop a road map for converting a small physician's office that is still using paper records to OpenEMR, an open source electronic health record, while using open source tools to implement and document the transformation. Documentation was made public on the OEMR wiki (at http://www.oemr.org/wiki/Going_From_Paper_to_Electronic) as a template for future implementations. This presentation is an overview of the documentation completed for the wiki. There are many paths to implementation, but the destination is meaningful use of the OpenEMR system.

Special Thanks: PLUG regular Keith Lofstrom was instrumental to the success of this project, not to mention Dr. Sam Bowen, MD in North Carolina and PLUG speaker Tony McCormick.

Diane Petersen is an emerging clinical informaticist, drawing from her formal education in clinical informatics and her extensive experience as a clinical pharmacist in a variety of settings. Having completed an internship leading and documenting the implementation of OpenEMR, an open source ambulatory electronic health record and practice management software application, Diane is in her last term of the Masters of Biomedical Informatics program at Oregon Health and Science University. She plans to apply her background and knowledge contributing to the improvement of managing healthcare data, and ultimately the improvement of patient care and outcomes.

UEFI Secure Boot and Open Source. It's not a 'general war against computation' by Vincent Zimmer, Intel

As 2012 platform firmware embraces UEFI 2.3.1 and ACPI5.0 support, the ability to interoperate with UEFI Secure Boot is imperative. This poses a unique challenge for open software that may not come pre-installed on the platform. With UEFI Secure Boot, though, infrastructure has been put in place to preserve openness, owner choice and control in addition to mitigating concerns of malware targeting the platform. This talk will provide a history of UEFI Secure Boot, an overview of the implementation, deployment practices, and details on the engagement with the open source community.

Vincent Zimmer is a Principal Engineer with Intel Corporation. He has been working on various platform, networking, trusted computing and security technologies around EFI since 1999 and platform firmware since 1992. Vincent has spoken in various forums on this topic, co-authored 3 books, 10 papers, and several specifications in this area.

Portland Linux/Unix Group Meeting

It's a little known secret that systemd is extremely capable of starting, controlling and regulating more than just system services, but can easily start an entire Desktop UI. Not many people have sat down and implemented and worked out the problems of starting an X service, a few UI components, the session bus and DBus services for normal users with the mechanisms that systemd provides.

The benefits are obvious: Systemd provides excellent service monitoring and restarting capabilities, provides socket and DBus activation for relevant services, and overall improves desktop startup by allowing user services to start well before core services like Xorg or wayland start. In effect, we're saying goodbye to XDG autostart entirely, and getting back reliability and scalability.

We converted several desktop environments including Tizen's Mobile UI, Xfce4, Enlightenment and more to systemd user sessions. We "pop the hood" and take a look at the implications for startup, what's possible to further improve on the session startup and where we can do better.

Auke Kok is a software engineer at Intel's Open Source Technology Center, and has been attempting to make Linux boot faster since 2007. In 2008, he co-presented the "5-second boot" with Arjan van de Ven at the first LPC. Since then, Auke has worked on further improving the Linux Core OS start sequence, first for Moblin and later with MeeGo, where we made the first switch to systemd. Auke now works on Tizen, which will heavily integrate systemd in the Core OS.
