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).

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.

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.

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.

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.
