CES 2016: From the Fringes

The Consumer Electronics Show in Las Vegas is the premier trade show for tech product previews and release announcements, going as far back as the VCR in 1970 to Driverless Cars in 2013*. This year the CES featured about 3800 exhibitors, spanning 2.47 million sq. ft. spread out over 3 locations** visited by 170,000 media and industry professionals — and I was privileged to count myself amongst them. Featuring keynote addresses from Intel, Netflix, IBM, Samsung, nVidia, Volkswagen and other big names, a lot has been written, presented and shared on mainstream as well as social media about the 4 day event. This chart sums it up the hype pretty well:

I decided to share some of my views from the fringes, rather than the trenches — there is no point in rinsing and repeating what is already out there, nor do I have any delusions about the value of my personal opinion about tech that enables your car to count how many oranges are left in your fridge (yes, it was demoed, with voice control).

Oculus_c

The Oculus Rift demo was by far the hardest to get into — there was a line, a line to get in the line, and a third holding area. Eventually I made it on the last day, and it took me about 20 min to recover from the simulator sickness caused by piloting EVE Valkyrie’s spacecraft from a living room chair. I still felt there were rough edges and the HTC Vive was by far a more refined, immersive and truly flawless experience. The new Sony PlayStation 4 VR was quite impressive as well: I could lean out of a moving car and look behind me, and the granularity of control was so good I could rotate knobs on the car stereo. OSVR.org based devices were quite popular too, and some others that caught my eye were Virtuix Omni active VR platform, AntVR’s Holodeck concept and ICAROS‘ EUR 10,000 gym equipment that lets you fly around in a virtual world powered by your own body. Certainly beats playing first person shooters wearing VR googles on a treadmill, or riding a virtual horse on a exercycle.

There were tons of clones (mostly based on Gear VR) and drones. Augmented Reality seems to be gaining ground, but despite solutions like the Sony SmartEyeglass and Daqri Smart Helmet, VR seems to be more popular of the two. It’s worth noting that virtually every VR or AR demo was running on Unity3D content, including those at NASA and IEEE’s booths.

I also tried my hand at racing simulators of various scales: from small VR setups, to actual cars mounted on motion platforms, to a massive 4×4 grid of 55″ OLEDs in front of a force feedback seat rig. There were several interesting display technologies on show: 3D without glasses, transparent (scaling up to entire walls), curved and Samsung’s modular, edge-blending display tech straight out of a sci-fi movie. Avegant’s Glyph might turn the display industry on it’s head, though, much like the way it’s worn.

On the automotive side, voice, gesture and intent based user interfaces seem to be gaining ground. Also making an appearance were adaptive user interfaces and improvements in sensor fusion, self-learning and self-driving techniques. There were tons of wearables, 3D printing and home automation booths. The two core themes seemed to be a maturing of the ecosystem (just about everything built on top of something else, not too many technologies solving problems from scratch) and apps for doing things that don’t need apps, like locking your front door. You’d think we would stop there, but no:

On the social innovation side, I found GrandPad, Casio’s 2.5D printing and the Genworth R70i Aging Experience very thoughtful. Besides these, I liked Mixfader‘s idea of an MVP slider for mobile DJs: after all, the crossfader is the main thing that requires precise tactile control, everything else can be relegated to the screen. Also impressive was Sony’s line of 409,600 ISO see-completely-in-the-dark cameras. And this is now a thing:

You’d also probably be able to find a lot of beautiful photos of Las Vegas on the Internet, so let me leave you with this video of a not-so-common Las Vegas activity that I squeezed in on the last day, courtesy of DreamRacing.com (very fringe-y because I picked a Nissan over a Ferrari). Thanks for reading!

* Apple, Google and Microsoft have their own tech events and despite the Xbox (2001) and Android devices (2010) being unveiled at CES, these companies tend to keep their product announcements exclusive to their own events. So no Hololens at CES.

Amuse UX Conference, Budapest

Last week, I had the privilege of being part of a group attending the first edition of AmuseConf on behalf of our company. Amuse is “an international conference for anyone interested in how to design and develop successful products that users love”. It’s organized by the same good folks that bring us the outstanding CraftConf year after year, sponsored primarily by Prezi and UStream (and SAP in case of Amuse). They did a near-perfect job, with only minor glitches with the seating and catering on the first day. Considering that the Big Data oriented CrunchConf was also literally next door, the event was practically flawless. Fast, uninterrupted WiFi and no food options for vegetarians/vegans remained a hallmark this organizing team (even though Tom Illmensee, event MC is himself vegetarian 😉 ).

(BTW, if you’re wondering why so many tech conferences are being hosted in Budapest, the event’s WiFi password should give you a hint):

20151103_083708867_iOS

510 attendees from 32 countries (as far away as Australia) made Amuse a roaring success, as did its impressive lineup of Speakers27% of the speakers were women, which is great for a tech conference — I hope next year we have even more!

Below is a summary of the talks I found the most relevant to my work. But by no means does that mean you should skip the other talks… depending on where you are and what you’re doing, you might be interested in some of the eclectic topics covered such as:

  • Designing web interfaces for children by Trine Falbe
  • Conducting research outside “sample of convenience” by Bill Selman from Mozilla Foundation
  • Design Thinking by Tobias Haug of SAP (my favorite quote: “Innovation = Execution x Creativity”)
  • How to get your dream UX job by Andrew Doherty of Google (worth checking out just for his mad presentation skills)
  • The Ethical Designer by Cennydd Bowles
  • Storytelling in a multidevice landscape by Anna Dahlstrom

Design Equilibrium

By Jonathan Lupo

Jonathan opened the conference with a very engaging talk drawing parallels between businesses and ecosystems: a “balanced exchange of value between Actors, Enterprise and Brand”. He gave practical examples citing the application of Lynn Shostack’s work on Service Blueprinting to a transformation in the healthcare industry. I strongly encourage viewing his inspiring talk on YouTube.

His core suggestion is a separation of Product Design from Service Design. The latter “fills in whitespaces between points of [rich] engagement provided by products”, helping to restore balance to the overall experience, and hence the business ecosystem. This is the real intangible value of services, as opposed to products.

He also proposed the concept of an “Engagement Model”: a framework to contextualize all the data a business collects.

UX: Design as a Science

By Joel Marsh, author of the UX Crash Course

Joel’s key message was that “Scientific UX Design is reproducible”: essentially drawing on the principles of the Lean Startup and applying them to the UX domain. His presentation was one of the most popular and engaging ones, and his quotes and examples garnered a lot tons of positive feedback. One thing that struck me was his exposition on the two types of creativity: Creative expression and creative problem solving. He noted that an over-applicability of creative expression can make you feel good as a designer, but result in an over-designed and bloated product:

ArtVsDesign

Another talk I would highly recommend watching when it comes out on UStream.tv.

Making Dog Food a Part of Your Balanced Diet

By Toby Sterrett

Toby used his work at Simple Bank to highlight the pros and cons of “eating your own dogfood”. The initial employees used the app themselves, and one of the downsides was that the missed revelation that users of such a smooth app had to deal with a paper form-based process to close their account, which took up to 20 days.

Another inspiring talk that you should definitely check out, full of quotes of wisdom like:

  • “Delight is design’s superpower”
  • A past discussion on Leadership strategy: “Build a shared vision, get the **** out of the way”
  • “UX is not about throwing technology at a problem, but throwing people at a problem”

On the other hand, Simple A/B tested as many as 16 variations of their login page (for more examples, check out UserOnboard.com).

How We Built Hotjar and Onboarded 50k Users in a Year

By Dr. David Darmanin

David used practical examples from Hotjar to support his model of “Drivers, Barriers and Hooks” when dealing with site visitors. He also put a quirky twist on some timeless wisdom:

The two most amazing insights for me were:

  • Hotjar captures every single customer interaction on a Trello board, and uses that feedback to prioritize their features.
    • They also make their roadmap public, which demonstrates their commitment and at the same time reduces enquiries about feature requests
  • They use the income from their paid customers to fund the creative freedom to build features for their free customers

The Invisible Interface: Designing the Screenless Experience

By Avi Itzkovich

Avi, founder of UXSalon, opened with a discourse on recent editions of Microsoft Productivity Future Vision. From there he led the discussion on towards a future without bigger and wider screens (which wouldn’t require “superhuman arm strength”):

  • “The most profound technologies are the ones that become invisible” 
    • Like automatically opening sliding doors
  • “Voice UI is the future”
  • “Gesture control is here to stay, but not on screens”

The Best Interface is No Interface

By Golden Krishna

Golden surmised that we are all “chipping away at digital chores”, and we don’t have to be “slaves to screens”. He has laid the foundations of the #NoUI movement with his book“The Best Interface is No Interface”. His excellent talk (slides here) was supported by book reading and real examples. Also, don’t forget to check out his accompanying toolkit on “how to create elegant solutions with no screens”.

For further inspiration to join the movement,  take a look at his Producthunt collection of “interfaces that require little or no time with screens”.

Magical UX and the Internet of Things

By Josh Clark

Josh opened with an announcement of his book release: “Designing for Touch”. His presentation was literally magical, complete with a wand, to the point that he managed to tie in together excerpts from preceding talks and put the whole conference in perspective. I found a similar slidedeck from one of his previous talks here, and I highly recommend taking a look at it while we wait for the official conference videos to come up on Ustream.tv. It was a treasure trove of out-of-the box examples like:

  •  Augmented REality Sandtable (ARES), which literally turns dirt into a high-tech, military-grade user interface… using not much more than a Kinect and projector
  • Grab Magic, which brings superpowers to data transfer
  • Propeller Health, which connects Asthma inhalers to phones for health monitoring

Josh’s key message was “interaction at the point of inspiration”: that we should think of “the whole world is an interface, just like it has always been”. He proposed “thereables” instead of wearables: bits of smart technology in the physical space where we would expect to interact with them, not something we burden ourselves by carrying or wearing all day long. To this end, he suggested that “the smartphone is Magic Wand 1.0 for everyone” and we should start thinking of it as just more than a screen.

IMG_4185

Regarding user interfaces, he had 3 bits of advice that I found remarkable:

  • “Technology should amplify our humanity”
  • “We shouldn’t educate users on how technology works, unless we really *have* to”
  • “Honor intention, don’t assume it”

Josh ended with a call to action:

Like this one.

 

 

 

 

 

Craft Conf 2015, Day 3

Continued from Day 2, here is a summary of talks I attended on Day 3:

From the Monolith to Microservices: Lessons from Google and eBay

By Randy Shoup | Video | Slides

Another eye-opening presentation with valuable insights, such as the fact that [a big organization like Google] doesn’t need architects, it just needs standardized communication and standardized interfaces. And that one of the biggest mistakes people make with microservices is reflecting the provider’s model instead of the consumer’s model. I highly recommend his talk, because it is based on the analysis of several Silicon Valley giants, successful either in the past or the present.

Interaction Driven Design

By Sandro Mancuso | Video | Slides

Sandro’s presentation was full of real examples rather than just theory. I had never heard of the Walking Skeleton before. It was an interesting intersection of DDD (Domain Driven Design), MVC-type architectures and SOLID principles, leading up to a pragmatic way of structuring and packaging software projects. Other advice from Sandro included modeling behavior, not state and not necessarily representing repositories as first-class citizens.

WebSocket for the Real-Time Web and the Internet of Things

By Peter Moskovits | Video | Slides

Not only was it an amazing presentation with live demos, Peter was also fully prepared with a backup plan for everything – including a PDF version of his presentation. After a historical perspective & technical explanation of how WebSockets work, he jumped into Kaazing demos which you can also experience online here. The most interesting was a kind of MVP for disseminating airline telemetry data (here).

Why Is An API Like a Puppy?

By Ade Oshineye | Video | Slides

RESTful APIs are not the solution to all of the world’s problems: Ade was short, succinct and insightful. The title of his talk reflected the fact that an API is an expensive long term commitment, it’s not just about the initial cost of software development. He got a lot of attention when he revealed that Google’s most successful API is AdWords, and it’s SOAP, not REST. Although REST is theoretically good, it doesn’t usually fit well with the real world consumer’s way of thinking. Another one of his gems was that if your [public] API is not being spammed/abused, then either no one is using it, or it’s happening and you’re not aware of it.

Implementing the Saga Pattern

By Caitie McCaffrey | Video | Slides

There wasn’t anything interesting to me during this time slot, so I decided to go with this one just for the Halo reference. There was just one picture of Halo. And a lot of “so” and “like”.

Techniques and Tools For a Coherent Discussion About Performance in Complex Architectures

By Theo Schlossnagle | Video | Slides

Theo decided it would be a good idea to plaster all his slides with huge pictures of steak. Anyway, after establishing that User Experience is measured in milliseconds, and that performance is also about the time spent between service layers, he covered distributed tracing systems such as Dapper and Zipkin.

IMG_3480

Great Engineering, Failed Product

By Marty Cagan | Video | Slides

Marty drew on decades of experience in Silicon Valley to summarize why great products and companies fail over and over again. I highly recommend watching his inspiring and insightful talk. Some of the things he touched upon while comparing successful and poorly performing teams:

  • Customers and company executives are a bad source of product ideas, because they don’t know what’s technically achievable
  • Developers are a good source, and so is Data (analytics, metrics, usage)
  • Multi-billion dollar projects are not based on a Business Case accurately predicting future revenue
  • Roadmaps are not a good indicator because Customers have other options available to them
  • Think Time to Money, not Time to Market – which means more than one iteration is involved
  • Product Managers are not mere [user] story writers – they need to have a deep understanding of the business, industry, customers and constraints
  • Most teams work in a way that gives them probably 20% of the benefit of Agile Methodologies
  • Value outcomes over output; think in terms of results, not projects
  • Successful teams run as many as 20 MVP experiments in a week – even if it involves hardware
  • Successful companies use an OKR approach to measure progress
  • The four product development questions:
    1. Will the customers choose it? (Customer Validation)
    2. Will they be able to use it? (User Experience)
    3. Can we build it? (Feasibility)
    4. Can our stakeholders support it? (e.g. Legality)

Craft Conf 2015, Day 2

I had the privilege of attending the second year of CRAFT, a tech conference in Budapest focused on software craftsmanship. The last year (which was the first time it was held) had completely blown my mind. A year later I still keep referring back to the talks and haven’t finished fully absorbing them and putting all those inspiring ideas into practice.

IMG_3467

In short…

Craft Conf 2014 was better. The speakers came from a more diverse background, the talks spanned a multitude of unrelated topics and I remember it being very, very hard to choose from talks happening in parallel. Each minute spent there was a revelation.

This year, though, many of the talks seemed to be plug for a company or a product, in disguise. Certainly there were brilliant takeaways, but not at the same scale as the previous year.

In my opinion, 2014 was also held in a better venue, although the 2015 venue was outstanding too, as far as tech conference venues go. But the rooms were too far spread out (the map was inaccurate), the acoustics were bad everywhere except the Main Room and unlike 2014, the WiFi was not flawless. Lastly, there were far fewer food choices, longer queues, no bottled water (even for the speakers) and therefore a lot of glasses clanking.

On the positive side, the schedule was followed down to the minute, the live video streaming was smooth and considering the scale of the event (1300 attendees), everything was beautifully organized. I’m not complaining – it’s just that the first CRAFT had set a pretty high standard.

(Video and Slides links will be updated by next weekend, when they become available)

Agile Engineering in a Safety-Critical World

By Nancy Van Schooenderwoert | Video | Slides

“Instead of freezing the ocean, learn to ride the waves” – Nancy’s talk was mainly about how our need for predictability for effective coordination is at odds with our need for fast learning to handle unknowns. She pointed out that in the agile context, “Architecture is any design decision that you cannot easily change”.

There was the customary reference to WikiSpeed to dispel the myth that hardware changes can’t fit within 2-4 week iterations. And an interesting one to a paper called TIR45 from AAMI: Guidance on the use of AGILE practices in the development of medical device software.

Coding Culture

By Sven Peters | Video | Slides

Sven’s talk was both informative and inspiring. Some of the key takeaways:

  • Innovation needs time
  • Stop and celebrate wins, however small they may be
  • Balance your passion for code with your passion for customers
  • Turn your passion into product
  • Value trust, autonomy and transparency (Atlassian achieves this by using chat over other communication means)
  • Products come and go, culture stays

Take a look at Atlassian’s Mood App and Stash Reviewer Suggester.

Building Reliable Distributed Data Systems

By Jeremy Edberg | Video | Slides

This one was good, until we went deep diving into the NetFlix Simian Army, which was also good but could have been summarized in just one slide. One thing that stood out from Jeremy’s advice was to “build for three”, because if you can overcome problems there then the solution can be [more] easily scaled up to n.

Don’t forget to check out NetFlix Open Source Software Center.

Oh! You Pretty Tools

By Andrew Bayer | Video | Slides

Andrew gave an interesting talk about the role of internal tools and their developers in the organization, covering both the pros and the cons. For example while making the build or buy decision, consider the fact that people are more expensive than software. And some thoughtful insights, like how Integration Tests can double-up as the roadmap to your tool’s usage. He also revealed that Cloudera runs ~2000 Jenkins CI builds every day(!)

The rest of it was basically about, and lessons learned from, CloudCat.

Testing and Integration (The Remix)

By Ines Sombra | Video | Slides

Ines entertainingly summarized everything we know so far, and topped it off with new insights for a good measure.  She emphasized:

  • The importance of lightweight short-lived branches so that CI is not overlooked
  • The more likely a test is to fail, the sooner you should run it
  • The testing of provisioning systems, such as Chef Recipes, too
  • How test setup time and parallelization are the key factors in minimizing the testing cycle time

She recommended this talk about the Google Build System.

Her punchline was that CI is a predictor of professional maturity at the organizational and individual level, and she ended with a “rantifesto” about building a culture of quality.

Beyond Features: Rethinking Agile Planning and Tracking

By Dan North | Video | Slides

From Cutting to Curing: Dan presented the powerful and inspiring idea that maybe software engineering is more like surgery than the civil engineering principles that we currently use to manage it. Agile methodologies essentially optimize for predictability, and this not necessarily a good thing. He mused on how a 2-week sprint is just enough time for a mini-waterfall, and thus we are all basically whitewater rafting.

After reviewing where the Agile Manifesto has brought us, he set an ambitious new goal to sustainably minimize the lead time to business impact. 

He ended with:

  • The role of Features, Delivery and Kaizen
  • Schedule, Measure, Track, Showcase
  • How Value Stream Mapping can reveal surprises like typically a piece of work spends upto 90% of it’s time waiting for dependencies

How To Save Innovation From Itself

By Alf Rehn | Video | Slides

For me, Alf’s talk was the highlight of the event. It was so good and so inspiring that I won’t even summarize it here. Go watch it!

______________________________________________

The day ended with a party thrown by EPAM, which included free beer, a DJ-saxophone duo and a surprise flashmob.

Such UI, Much Refactoring

As the entry barrier to developing software gets steadily lower, as agile development practices (release early, release often) gain popularity and as the success stories coming from continuous and/or early feedback become industry legends, we find ourselves in a world where perfection is no longer a differentiator, it is an unspoken expectation and an implicit requirement. This applies even to products and services that are virtually free for the consumer. When was the last time your social network was down? Or your maps app crashed? Or you discovered a bug in your favorite (modern) web browser? For that matter, do you even know (or care) which “version” of software you are using?

Welcome to the new reality of iterative perfection.

But iterative perfection brings with it the cost of iteration: the cognitive load on the user having to continuously re-learn, re-orient and re-familarize. I’m not referring to the the step change introduced by MS Office Ribbon UX, or desktop apps migrating to Web UI interfaces… But smaller, mostly less disruptive tweaks and updates (usually referred to as “minor improvements”). While many of these affect the inner workings or performance, a seemingly high proportion directly affect user experience. In the spirit of the development process they hatch from, these changes are small & frequent, and are sometimes even rolled back if found to be unpopular. A fashionable “iteration” these days seems to be changing the colors or shapes of icons or other UI elements.

Making a product faster, more stable or more secure is one thing, but is tweaking the user interface of a product that is already in production a good thing? Does familiarity breed contempt, or confidence? There was a time when building a great product was given due recognition – success had been achieved, the job was well done, lessons were learned and everyone moved on. These days we change things – partly because we are expected to, but mostly just because we can.

mib_look_good

Think about it. Once an idea has been commoditized by a company, what is the motivation for further innovation? The trend these days in web products is to keep revamping the User Interface every few months (sometimes weeks). To me, that is a reflection of a bigger issue than vying for the often limited attention span of modern consumers (through brighter and shinier objects).

What I think really happens is this: A bunch of smart people are hired, they build something great together, but now neither does the company want to let go of them (they’re smart, committed employees) nor do they have a plan for what ought to be built next. So, they resort to iterations and improvements (often poorly made choices to emulate a successful but unrelated product) to keep the “resources” or “talent” busy. Maybe sometimes the boredom gets so much that the only way of injecting vitality into what was once an awesome startup is to acquire one (which seems to be happening a lot these days, at atrocious values).

Secondly, having a continuous release schedule [perhaps subconsciously] puts pressure on the development team to deliver some tangible change with each release. After there is nothing left to add or take away, well, there is still the user interface.

I think as engineers, UX practitioners, software developers, product managers and builders of things, we all ought to learn how to recognize perfection when we have achieved it. We need to iterate less and progress more.

Update 2015-02-18: What Happened to Apple Design? by Jose Berengueres mirrors some of these thoughts.

User Stories vs “The User’s Story”

Last year I bought DiRT3 for Windows DVD on sale. Based on its ratings, It seemed a good candidate to try out my Poor Man’s Xbox: An Xbox WiFi controller connected to a Windows laptop, hooked up to the TV.

Even though I had bought a DVD, it wanted me to register online with a Windows Live ID. Well, if I wanted to play a game online, there are plenty of options. Why would I buy a DVD? So every time I started the game, I would select some fake name, configure all my settings (controller, driving aids and so on). But because I had refused to sell my soul, the game wouldn’t save my settings locally.

After a few times I got fed up and decided to create an ID. How hard could it be, right? Right?

reality

Let the Games Begin

It had read before on that gmail addresses can be used for Live. So I provided mine at the game startup. A few “Next” clicks later, it refused to recognize it. Then:

  1. Exited game
  2. Fired up web browser
  3. Went to Microsoft site
  4. Registered my gmail ID for the Live service. What fun, a verification email was sent.
  5. Opened gmail
  6. Clicked on verification mail. Read through cheesy welcome notice.
  7. How cool! Now I have a free Xbox Live gamertag. Which I can change. For free. Only once.
  8. Decided if my profile was going to be online, might as well use a gamertag that my friends would recognize. Isn’t that the whole point of social gaming?
  9. Changed gamertag. Now my Xbox Live page was in a state where the new gamertag appeared in some places, and the original was still retained in others (e.g. the logout option)
  10. Logged out, logged back in to make sure the change had taken effect (standard Microsoft workflow: If it acts weird, restart it)
  11. Still the same. OK, whatever. But wait… in doing all this experimentation I discovered “Privacy Settings”.
  12. Changed my privacy settings to sane ones. Hopefully they were mine, because they still referred to the original gamertag.
  13. Finished, closed browser
  14. Fired up game

You’d think that 14+ steps to register for playing a game would be enough. But no. Now that I had a valid XBOX Live ID, I could log in. And now that I had logged in, I needed the latest updates to the XBOX Live gaming system installed on my laptop. Someone had decided to reuse code for this: it would be installed as a Windows update! And guess what, after that I had to restart my laptop, too! Because apparently only selling your soul just doesn’t cut it these days.

But finally I was getting close. I had restarted laptop and game, logged in and voila! Since by registering online I had clearly indicated that I’m heavily into social gaming and all that, now I was being asked to supply my YouTube credentials so in-game video could be uploaded to my channel. Which doesn’t exist.

Past that , the game wasted some more seconds checking for Downloadable Content. Which I was least interested in, considering that I had barely even played the game yet. But, it still checks every time I start the game. The exact same check every time, which notifies me about the exact same shiny new packs available, which I’m exactly as disinterested in.

And here is the highlight of the whole experience: After going through the effort of registering online, I still have to re-configure my settings every time I start the game. Because apparently saving a few strings of text to a file requires something more that investing in a laptop, operating system, DVD and Internet connection. In the attempt to play this game, I spanned 2 types of storage media and 4 internet services,  gave up my privacy and recreational time, and it still forces me to use factory settings. On the other hand, the graphics are a generation ahead, the menu has 3D text and the game makes the CPU generate unbelievable amounts of heat. Which is exactly how things were back in 1996.

Conclusion

1. User experience and usability are not just about product features. They are also about the experience of reaching the point where the product can be used. Any software that requires more than 10 steps and an hour of time is unusable.

2. In the year 2014, the only reason I should be forced to restart my computer is to prevent catastrophic meltdown. Not to install updates. What’s next, autonomous cars pulling over on the side of the highway and restarting because the manufacturer decided to push updates?

(EDIT: I wrote this as a joke but a reader pointed out that this is actually happening right now: Where’s my Knight Rider 2000?)

3. This whole experience stank of multiple individually proven and smooth solutions sloppily strung together to deliver working software. I can bet Codemasters and/or Microsoft were thinking they were being agile, leveraging reusable components and delivering in an impossible schedule. All the user stories were delivered, but did anybody step back and think of the user’s story?

Takeaways from Craft Conference 2014, Budapest – Day 3

Continued from Day 2, here are the talks from Day 3 in order of my personal preference (and relevance) which may differ from yours:

Complex Projects aren’t planable but controllable

by Jutta Eckstein (Slides | Video)

Sadly, Jutta’s slides aren’t available online but the talk was packed with solid advice for Project Managers. Some of them were:

  • Our predictions are usually based on a coherent story, not a complex, dynamically changing reality
  • Targets should be ambitions, not absolute
  • Focus on the value gained, rather estimates of the effort required
  • Having an  annual budget is like having a bank that opens for business only once a year
  • Annual budgets are not optimal because they are never underutilized: the excess (if any) is still used up, never returned back
  • Consider [event-based] rolling budgets, rolling plans and rolling control
  • Check value and progress regularly
  • Don’t just trust the experts, seek feedback from diverse groups
  • Have different planning strategies for Roadmap (themes only), Release (features based on value & velocity) and Iteration (Stories based on value (+estimate) & velocity)

Architecture War Stories

by Stefan Tilkov (Slides | Video)

Probably the most amusing talk of the event. Stefan shared some hilarious real-life examples of architectural disasters… some of them still very much in use (of course no names were revealed). His advice was to go back to the basics:

  • Make data free of code dependencies
  • If it makes you want to pull your eyes out, maybe you shouldn’t be doing it
  • Better ask for forgiveness than permission
  • Development environment is not the same as production environment
  • Feedback, reflection, iteration

Responsibly maximizing craftsmanship in software engineering

by Theo Schlossnagle (Slides | Video)

Theo revisited the basic problems plaguing software development today and went on to share some of his experiences at Circonus. One of the tips was to treat all software you write as open-source within the organization, even if you don’t plan to release the source outside. Other highlights:

  • Turtles all the way down: Software at scale is tied together with loose string & hope
  • We use human language to describe software specifications, and this can be interpreted by different people in different ways (like poetry)
  • Technical debt is non-linear; large monolithic components are more likely to fail because they are hard to maintain
  • Reusability is good, but use the right tools for the right purpose. Accept that that right tool may not yet exist and may need to be written
  • Diversity is an emergent property of scale
  • Thou shalt be judged by your API

For software developers, the message was loud and clear:

Data-Driven Software Engineering

by Jevgeni Kabanov (Slides | Video)

Jevgeni went thorough the effort of analyzing 1000+ projects on Productivity, Quality and Predictability. Sadly the slides aren’t available, but the raw data they were based on is. You can still watch the video and grasp the most important points, such as the fact that the best software projects are delivered 80% of the time on schedule and still have 25% critical issues. Or that automated tests improve quality by 26%. There were also secondary interpretations such as code reviews improve architecture, not just code quality.

Jevgeni emphasized on the importance of measure & experiment over simply “doing agile”. Some suggestions for measurement were:

  • Deadline misses
  • Scope changes
  • Blockers after release
  • User satisfaction

The presentation became a bit controversial later but as Jevgeni said: “People, chill – I gathered data and presented my analysis – feel free to take the data and do a better job”. And I think this talk had the most creative closing slide ever 😉

Without Present or Past: How to Think Distributed – The Hard Way

by Endre Sandor Varga (Slides | Video)
By far the most profound and philosophical talks at Craft. If you have an interest in Distributed Systems, AI or Information Architecture, I would strongly recommend watching the video. The core concept was based on applying epsitemic thinking to systems that are distributed, concurrent, able to fail independently, and communicate over a lossy medium with non-deterministic communication delay. Endre touched upon:
  • Two Armies Problem
  • The final important message
  • Difference between actual state and observed state
  • The Omnipotent Observer (doesn’t exist, because state is always queried)
  • Global introspection and self-awareness
  • Cone of the past
  • The present is volatile and subjective
  • Going from someone knows -> someone knows everyone knows -> everyone knows everyone knows

Endre ended with this advice:

  • Have a properly defined failure model
  • Never assume reliable communication
  • Never assume common knowledge

Functional Reactive Programming in Elm and JS

by Evan Czaplicki (Slides | Video)

Evan is the designer of the Elm language and his enthusiasm is infectious. Over the course of his talk, he built and demonstrated a simplified (yet slick) Mario game complete with physics and reaction to keyboard inputs. Elm is a Functional Reactive Programming language for web browser based GUIs and this game was a fine demonstration of concepts that Bodil Stokke and Jonas Boner touched upon in their respective talks.

There is no doubt that Elm is a game-changer. Here is another example of traffic simulation.

Find the Right Abstraction Level for Your Tests

by Gerard Meszaros (Slides | Video)

If you’ve ever been haunted by the question of what level of testing is enough (and who hasn’t?) then this presentation was for you. The key message was to think in terms of not what you can add, but what you can leave out of the test: “if it isn’t essential to conveying the essence of the behavior, it is essential to not include it”. Over 39 slides, Gerard illustrated this step-by-step with one, continuous, easy-to-follow example.

Software Psychology: The Art of Listening to Code

by Bjorn Freeman-Benson (Slides | Video)

Bjorn talked about the concept of code screams: behavioral indications of a deeper problem in the system. For me the key takeaway was that you should continuously monitor your processes as well as your systems in production (e.g. by gathering usage statistics) and fix the root cause when a problem is found.
