- Intel On-Device Voice Recognition (Quartz) — interesting because the tension between client-side and server-side functionality is still alive and well. Features migrate from core to edge and back again as cycles, data, algorithms, and responsiveness expectations change.
- Meet Microsoft’s Personal Assistant (Bloomberg) — total information awareness assistant. By Seeing, Hearing, and Knowing All, in the future even elevators will be trying to read our minds. (via The Next Web)
- Microsoft Contributes Cloud Server Designs to Open Compute Project — As part of this effort, Microsoft Open Technologies Inc. is open sourcing the software code we created for the management of hardware operations, such as server diagnostics, power supply and fan control. We would like to help build an open source software community within OCP as well. (via Data Center Knowledge)
- Open Tissue Wiki — open source (ZLib license) generic algorithms and data structures for rapid development of interactive modeling and simulation.
Ad Triumphalism, Education Not Transformed, Bookstore Infrastructure, and Tossable Camera
- Why The Banner Ad is Heroic — enough to make Dave Eggers cry. Advertising triumphalism rampant.
- Udacity/Thrun Profile — A student taking college algebra in person was 52% more likely to pass than one taking a Udacity class, making the $150 price tag–roughly one-third the normal in-state tuition–seem like something less than a bargain. In which Udacity pivots to hiring-sponsored workforce training and the new educational revolution looks remarkably like sponsored content.
- Amazon is Building Substations (GigaOm) — the company even has firmware engineers whose job it is to rewrite the archaic code that normally runs on the switchgear designed to control the flow of power to electricity infrastructure. Pretty sure that wasn’t a line item in the pitch deck for “the first Internet bookstore”.
- Panoramic Images — throw the camera in the air, get a 360×360 image from 36 2-megapixel lenses. Not sure that throwing was previously a recognised UI gesture.
Chicago Code, 3D Smithsonian Data, AI Controlling Everything, and Game TCP
- The Virtuous Pipeline of Code (Public Resource) — Chicago partnering with Public Resource to open its legal codes for good. “This is great! What can we do to help?” Bravo Chicago, and everyone else—take note!
- Smithsonian’s 3D Data — models of 21 objects, from a gunboat to the Wright Brothers’ plane, to a wooly mammoth skeleton, to Lincoln’s life masks. I wasn’t able to find a rights statement on the site which explicitly governed the 3D models. (via Smithsonian Magazine)
- Anki’s Robot Cars (Xconomy) — The common characteristics of these future products, in Sofman’s mind: “Relatively simple and elegant hardware; incredibly complicated software; and Web and wireless connectivity to be able to continually expand the experience over time.” (via Slashdot)
- An Empirical Evaluation of TCP Performance in Online Games — We show that because TCP was originally designed for unidirectional and network-limited bulk data transfers, it cannot adapt well to MMORPG traffic. In particular, the window-based congestion control and the fast retransmit algorithm for loss recovery are ineffective. Furthermore, TCP is overkill, as not every game packet needs to be transmitted in a reliably and orderly manner. We also show that the degraded network performance did impact users’ willingness to continue a game.
Operating on the edge and real-time performance emerged as key themes at Velocity NY.
Maybe it was the hustle and bustle of Times Square just within earshot. Maybe it was the smell of that legendary pizza on every corner. Or maybe it was having a front row seat in the financial capital of the world while the drama of a possible government default played itself out like a Broadway show. Whatever it was, Velocity New York felt markedly different than its west coast cousin.
But discussions on scaling the operations of the squishy side of the organization–developing healthy team interactions, talking through the realities of the ever-elusive DevOps culture, and what it all means to scaling not just web sites but full-fledged businesses–were more present than ever.
Velocity 2013 Speaker Series
I want to start by thanking John and Steve for the warm welcome. They’ve created something very amazing with Velocity, and I’m excited to be a part of it.
It might seem a bit odd to talk about What’s Next at the beginning of a conference, but I figure the best time to go to the bank and ask for a loan is when you actually have some money.
What we’ve been talking about at Velocity, especially the DevOps side of things, is only the tip of the iceberg when it comes to how businesses are changing. And that shift is from the sequential to the concurrent. It used to be that we threw things over a series of walls, from Product Management to Design, to Development, to QA, to Production, to Customer Service and so on. That was an old world of software and one-year development cycles.
How you handle failure can mean the difference between "just another incident" and a revenue-stealing accident.
I was ready to get home. I’d been dozing throughout the flight from JFK to SFO, listening to the background chatter of Channel 9 as a lullaby. Somewhere over Sacramento, the rhythmic flow of controller-issued clearances and pilot confirmations was broken up by a call from our plane:
“NorCal Approach, United three-eighty-nine.”
“United three-eighty-nine, NorCal, go.”
“NorCal, United three-eighty-nine, we’d like to go ahead and…”
My headphones went silent, Channel 9 shut off.
I didn’t think too much of it as we continued our descent, flight attendants walking calmly through the cabin, getting us ready for landing. I had noticed our arrival path was one I was unfamiliar with, but nothing else seemed out of the ordinary… until we turned onto the final approach. In the turn, I noticed the unmistakable glint of firetrucks’ rotating red lights, lined up alongside the runway.
Velocity 2013 Speaker Series: Focus on Web Apps, Not Web Pages
We’re not making web pages anymore; we’re building web applications. Gone are the days of a few script tags in the <
head>. Apps today are a complex web of asynchronously-loaded content and functionality. In the past decade, we’ve progressed from statically-loaded HTML to AJAX-ifying all the things. However, the way we’ve been measuring real user performance of our apps hasn’t changed to reflect our new state of art.
At what point during page load do users consider an app to be “ready enough” to start using? If we use standard performance metrics, we have to choose one of the following:
1) When the HTML document has been completely loaded and parsed, but before stylesheets, images, and subframes have finished loading (
2) When all synchronous scripts, stylesheets, images, and subframes have finished loading (
If we pick
DOMContentLoaded, it quickly becomes clear that there’s no inherent correlation between the app state at that point and what a user would consider “ready.”
Velocity 2013 Speaker Series: A Sneak Peek With WebPagetest and Appurify
Now that more companies have basic mobile strategies in place, they are turning their attention to the issue of performance.
Mobile developers are thinking about how fast their apps and mobile webpages load and—more importantly—what they can do to make them faster. Consumers have little patience for slow loading apps and their expectations are only going to get more stringent. This expectation likely contributed to Apple making changes so that apps on iOS 7 load 11% faster than on iOS 6.
The challenge is that measuring performance for mobile is not as easy as it is for web. Many of us have used tools like WebPagetest to assess website performance across different browsers/locations and pinpoint areas for improvement but fully functional, equivalent tools don’t exist yet for the mobile space.
This has left mobile developers ill equipped to create the highest-performing mobile apps and websites.
Velocity 2013 Speaker Series
There’s an old joke about the aviation cockpit of the future that it will contain just a pilot and a dog. The pilot will be there to watch the automation. The dog will be there to bite the pilot if he tries to touch anything.
Although they will all deny it, the majority of modern IT developers have exactly this view of automation: the system is designed to be self regulating and operators are there to watch it, not to operate it. The result is current systems are often inoperable, i.e. systems they cannot be effectively operated because their functions and capacities are hidden or inaccessible.
The conceit in the pilot-and-the-dog joke is that modern systems do not require operation, that they are autonomous. Whenever these systems are exhibited, our attention is drawn to their autonomous features. But there are no systems that actually function without operators. Even when we claim they are “unmanned”, all important systems have operators who are intimately involved in their function: UAV’s are piloted, the Mars rover is driven, the satellites are managed, surgical robots are manipulated, insulin pumps are programmed. We do not see these activities–many are performed by workers who remain anonymous–but we depend on them.
