I hate type errors!

I hate type errors!

Even though the Unison editor isn’t yet suitable for real programming, my experience using it has made me even more aware of just how much time programmers waste dealing with type errors:

  • Let’s say 95% of errors are trivial to fix. You probably don’t even bother reading the message. A quick look at the line number and ten seconds of thinking and you know the fix. Flow is maintained. Your focus stays on what matters—making the actual edits to the code. You’ve made an edit, and the compiler has helpfully pointed out a missed or incorrect step, which you immediately rectify. This is why people like type systems.
  • In 5% of the cases, the error message(s) are misleading and/or point to the wrong location(s). You take a look, scratch your head. 30 seconds go by; it becomes clear you aren’t going to intuit this one. Now you actually have to gather more information. Okay, maybe you’ll start by reading that error message more carefully. Is the information useful? Maybe. Maybe you try a change, use typed holes to gather info about the types of values in scope, etc. But recognize that you are now in full-on yak-shaving mode. You started off by conceiving of some edits to your code. You then made these edits, but now look—you aren’t productively fixing your mistakes or providing missing steps, you are engaged in a very inefficient search process to narrow down and understand what the problems even are.

Note that if we deferred our typing errors until runtime as in a dynamic language, we wouldn’t have to spend any time deciphering type errors, and the runtime errors would now be in terms of actual program values that we can inspect, rather than a possibly inaccurate symbolic description of the problem. Of course I feel this is throwing the baby out with the bath water—static types are overall a huge win especially in languages like Haskell with nice type systems. But I point this out because I think it’s important to develop some perspective.

When you start out doing typeful programming, perhaps that 95% is more like 60%. A very large number of error messages you get from the compiler are frustratingly opaque. What the hell is the compiler even talking about? Some people in this situation get frustrated enough that they leave the typeful programming world in favor of some dynamic language. But if you stick with it, over time, with experience, you get better at intuiting what the issues are or avoiding them in the first place, and the 60% creeps up to 90%, 95%, 96%, 97%… But here is the problem: in getting to this point, you have brought the cost of deciphering errors down to acceptable levels but also lost perspective on the cumulative costs. The past costs are forgotten and the present costs are ingrained in your workflow and thinking, a productivity tax you don’t even really notice or think about.

Aside: I consider this a problem with our industry and education system. We are raising generations of programmers implicitly taught to accept everything as a given, no matter how arcane or costly. But in software, nothing is a given, every single aspect of the software world is the result of choices made by people “no smarter than you”.

But even for people with experience, the costs of deciphering type errors is much higher than that 5% would indicate. The issue is not the direct costs due to time wasted deciphering type errors, it’s the indirect costs. Programming is an activity that demands focus. When focus is maintained, it is possible to accomplish tasks in hours that might otherwise take weeks. Maintaining a state of flow for longer periods of time is an almost trancelike experience, and incredibly empowering. One feels attuned to the tasks at hand, subtasks get pushed and popped from the stack, and there is a feeling of directness, control, and creative energy.

But maintaining this level of focus is rare. We don’t like to talk about it, but if we are being appropriately humble about our limitations, we must recognize that human focus is a very scarce and very fragile resource. Our puny little brains can only allocate so many resources, and us programmers are constantly losing focus. I don’t mean obvious distractions like wasting time checking Twitter or Reddit when you should be doing something. These things are often the symptom, rather than the disease. What I mean is the act of doing things that aren’t the actions most likely to be most productive at furthing progress. Everyone knows what that feels like. Perhaps you are debugging, and rather than methodically narrowing down the problem via a set of well-chosen experiments each giving maximal information, you instead meander around, perhaps adding random print statements or inspecting random values in the debugger. When you should step back and go for a walk perhaps, you instead stare at the screen. You’ve lost focus, but before you realize it and do something productive about it, you’ve lost an hour.

Deciphering type errors leads to exactly this same sort of inefficient, meandering, unfocused mode of work, perhaps on a smaller scale. But the costs are still there, and they are substantial, if you pay attention.

Introducing People

by Richard Millington

You’ve been through as many patronising icebreakers as I have.

Here’s a better way of doing it:

"What if instead of introducing your friend as Jennifer the nurse, you started introducing her as Jennifer, one of most thoughtful people you know, or Jennifer the friend who helped you move in when you didn’t know a soul in this city.

Introducing your friends for who they are rather than focusing on what they do will remind them they are loved before and beyond their titles. It’s an easy way to remind them that you see them for their hearts instead of their accomplishments.

I want people to know my friend Carolyn is amazing at her job, but more than that, I want people to know the stuff inside her that makes her a great friend."

Today is my last day at Mozilla

by Doug Belshaw

TL;DR: I’m leaving Mozilla as a paid contributor because, as of next week, I’ll be a full-time consultant! I’ll write about that in a separate blog post.


Around four years ago, I stumbled across a project that the Mozilla Foundation was running with P2PU. It was called ‘Open Badges’ and it really piqued my interest. I was working in Higher Education at the time and finishing off my doctoral thesis. The prospect of being able to change education by offering a different approach to credentialing really intrigued me.

I started investigating further, blogging about it, and started getting more people interested in the Open Badges project. A few months later, the people behind MacArthur’s Digital Media and Learning (DML) programme asked me to be a judge for the badges-focused DML Competition. While I was in San Francisco for the judging process I met Erin Knight, then Director of Learning at Mozilla, in person. She asked if I was interested in working on her team. I jumped at the chance!

During my time at Mozilla I’ve worked on Open Badges, speaking and running keynotes at almost as many events as there are weeks in the year. I’ve helped bring a Web Literacy Map (originally ‘Standard’) into existence, and I’ve worked on various projects and with people who have changed my outlook on life. I’ve never come across a community with such a can-do attitude.

This June would have marked three years as a paid contributor to the Mozilla project. It was time to move on so as not to let the grass grow under my feet. Happily, because Mozilla is a global non-profit with a strong community that works openly, I’ll still be a volunteer contributor. And because of the wonders of the internet, I’ll still have a strong connection to the network I built up over the last few years.

I plan to write more about the things I learned and the things I did at Mozilla over the coming weeks. For now, I just want to thank all of the people I worked with over the past few years, and wish them all the best for the future. As of next week I’ll be a full-time consultant. More about that in an upcoming post!

Inner Vision for the weekend of March 27, 2015

“I go to bed with the sun, and I wake up with it. I don’t feel like I’m trying to race time.” – Snowboarder Mike Basich's 225 sq. ft. cabin sits atop of 40 acres, fed by two creeks, near the nature he craves.

There’s a plenitude of sites (including our own) recommending and rating just about everything made by mankind. But as important as “what to buy” is knowing what’s possible using the products you’ve purchased. Inner Vision is a weekly digest connecting the dots between great everyday objects and the culture and techniques behind living well with them.

Here's a good reason to keep worn out toothbrushes: they're ideal for cleaning the dirty snagged zippers strewn across camping gear like tents and backpacks.

Here’s a good reason to keep worn-out toothbrushes: They’re great for cleaning out dirty, snagged zippers strewn across camping gear like tents and backpacks.

Oh, Gear! I was going down this list of outdoor gear maintenance and repair tips, mumbling “yup” and “uh-huh” aplenty. But when I got to the section about storage practices, I realized I’ve been doing it all wrong when it comes to pads, tents, and sleeping bags: stuffing instead of folding, storing pads rolled up instead of rolled out, keeping our gear in the garage instead of the closet. Amongst the common-sense tips are a few gems of wisdom for anyone who regularly likes to gear up then get out.

Our Actions of Distractions: David M. Levy’s resume includes a long stint at Xerox PARC, so there’s no questioning his inquisitive nature and his technology bona fides. Now a professor at the Information School at the University of Washington, he’s diving in with similar curiosity and passion in the hopes of uncovering a sweet spot—a “contemplative balance”—between our offline and digital lives in an era when our attention span is measured in minutes, if not seconds.

Why Being “Always On” Is a Turnoff: The only thing worse than feeling like you have to send out a late-night email is being the recipient of one. Just stop it and consider adopting a practice one company calls “zmail,” where emails between 10 p.m. and 7 a.m. during the work week and all day on weekends are highly discouraged.

How much will cost me to keep watching HBO, ESPN, Amazon Prime, and Netflix programming sans a cable subscription? About $52.

The Cord-Cutter’s Calculator: It seems inevitable that one day we’ll all get to pick and choose our own TV-watching adventure. But for now cable-cutting may not really be the best money-saving measure, depending upon your channel viewing preferences. This interactive calculator will help determine the “what” and “how much” according to your stream team of channels and services.

Challenging You One Step at a Time: Want to change your life in 52 weeks? No, this isn’t a challenge tied to a beach body, new fad diet, or even in praise of the best fitness tracker—all it takes is committing to hiking just once a week for those 52 weeks, hopefully inspiring those around you to get out and do the same.

One Slow Take: For those seeking a little relaxation instead of the previously mentioned physical challenge, may I recommend this 4K-resolution, 93-minute single-take video of a container ship traversing the South China Sea from Vietnam to China? It’s strangely mesmerizing, poetic in its dreamy repetition as water, waves, and the sky eventually merge into one.

The Lizard Pose is one of five yoga stretches recommended for runners to conclude their mileage with.

The Lizard Pose is one of five yoga stretches recommended for runners to conclude their mileage.

It’s a Stretch: I should start off by stating I’ve long avoided yoga. A combination of a bad 2-hour Bikram session years ago and “I was born like this!” tight hamstrings have long compelled me to run away from the sight of yoga mats and the challenge of holding a pose longer than a few seconds. Yet, it’s because I do enjoy running—trail running—that I realize yoga can be effective at curtailing injuries. So here I am, downward doggin’ it.

Be a Jerk at Home: Modern Caveman’s step-by-step tutorial shows how to turn a big piece of beef brisket into dehydrated strips of tasty goodness, all without a food dehydrator. Salivary glands, activate!

In Praise of Good Enough: The Wirecutter and The Sweethome abide by the belief “the best” isn’t always necessarily the best for everyone. Sometimes budget, space, or intended use require a more affordable, smaller, or lesser-featured design. And then there’s something to be said about settling for what you really need rather than obsessing over what you want. Happiness and satisfaction can sometimes be found in “good enough.”

Got an interesting story, link, resource, or how-to you think we should check out for consideration for our next issue of Inner Vision? Drop us a line with the subject “Inner Vision” and we’ll take a look!

Waterloo startup Medly Labs debuts music creation app for iPad

by Daniel Bader

Making music is hard. To someone unfamiliar with its language, the notion of reading symbols on a paper and transmuting them to one of a number of absurdly complex and beautiful instruments is often overwhelming and seemingly impossible.

And yet humans connect with music on a cellular level; brain scans have shown that one’s response to hearing a beautiful aria or jamming to a great guitar solo evokes feelings similar to the appreciation of a great meal, or even, with favourite songs, the love of another person.

The mystery around our connection to music has deepened even as our access to it has both simplified and commoditized. It’s remarkably easy to access nearly every song ever recorded, for a low monthly fee, and to do so almost anywhere, in any situation.

But while the consumption of music has eased, the creation of it has not. It still takes an expert hand, a steady work ethic and a fair amount of trial and error to write something that one would consider a song, but the digitization of tools have led to a proliferation of tools, both for experts and beginners, that make it easier to create something that resembles music.

Medly Labs began its life at the University of Waterloo, winning $25,000 as one of the finalists in VeloCity’s Spring 2013 Venture Fund pitch-off. Back then, the company, and the app, was called SoundBrush, and quickly grew to be one of the easiest ways to create music on the iPad.

The app’s name alluded to its main input method: users painted, as with a brush, a series of musical notes on an endless roll, with the option of switching between one of a number of instruments. After a number of updates and over 300,000 downloads, SoundBrush disappeared, as did the company with the same name.

Co-founder and CEO of the newly-renamed Medly Labs, Basil Al-Dajane, wouldn’t tell me why the company abruptly removed SoundBrush from the App Store, but it was likely due to a trademark dispute with a music label of the same name.

Now, with a revamped brand and renovated app, Medly is set to inspire a whole new group of music novices to create music in a similar fashion.

“What Paper is trying to do with drawing, we’re trying to do with music,” Al-Dajane tells me. Paper, the popular drawing app that many consider the best example of using the iPad as a creation tool, is clearly the inspiration for Medly’s user interface and experience.

As users move along the virtual roll, adding and modifying notes on a beat, they can navigate forward and backward using two fingers, or undo the last few additions with a counterclockwise three-finger circle.

Like Paper and its various utensils, Medly users get a free starter instrument pack featuring piano, drum kit and synthesizers. But with 78 instruments in total, the rest are divided into separate $2 packs, with the entire Band Pack collection available for a one-time $8 fee.

With so many options, though, Medly users can quickly find themselves overwhelmed by choice; the company plans to ease them into the workflow with six free demo songs, easily customizable, and a number of in-app and video tutorials.

“Everyone has a song in them,” says Al-Dajane, who tells me the team has been quietly working on Medly for nearly 18 months, trying to make it as easy as possible for novices to pick up and use.

“Medly is very much targeted towards the music novice. We painstakingly took a lot of time to remove as much music terminology, and abstract away music concepts as possible, so users can really dive in and make music.”

Music creation isn’t something new to mobile, but it continues to be one of its most lucrative and varied app genres. One of the best-known examples is San Francisco-based Smule, which became well-known for its dirt-easy AutoRap, Ocarina, Songify and Guitar! apps, though it may best be known for I Am T-Pain, which blew up around the time AutoTune was ubiquitous in almost every pop song.

Medly approaches things differently, and a bit more earnestly, than Smule, but it maintains the simplicity of wanting to make the act of creation just as easy.

I played with a beta version of the app prior to its release Wednesday, and while I found it tremendously enjoyable to combine the rapid timbre of a snare drum with the dulcet release of a baritone saxophone, I was completely lost in my attempt to create a song.

While the app lacks a direct social component, users have the choice of sharing a completed song to Facebook, YouTube or Twitter, either as an audio or video file. And because no piece of art is truly ever finished, Medly allows users to export the entire song file itself to others can take a stab at improving, or remixing, what’s already there.

Music, like drawing, is hard.

Medly is available for free for iPad on the App Store.

We have a Samsung Galaxy S6 and S6 edge. Ask us anything!

by Daniel Bader

Sometimes, we’re pretty lucky in this country. Yeah, it may be cold a lot of the year, and concert audiences tend to show their fair share of ambivalence, but overall it’s a pretty good place to live.

This year, we were lucky to get Samsung’s latest flagships a few weeks before the rest of the world, and have had plenty of time to play with both of them. By now, we’re pretty familiar with battery life, performance and other nuances — things that some of the other tech sites only receiving their devices this week wouldn’t have the answers to just yet.

While they’re not running final software, and as we’re working on our Galaxy S6 edge review, we thought we’d take some time to answer some questions from you guys.

And just to refresh your memory, the devices are coming to Canada on April 10th on practically every carrier, with the 32GB S6 starting at $250 and the 32GB S6 edge starting at $350.

We’ll try to get to as many as possible in the comments below. Have at it!

The best frameworks are apps

The best software frameworks are apps that do things users care about.

Back in the 80s it was dBASE and then FoxBase. 1-2-3 had a macro language, it was weak, but it was widely used because 1-2-3 was so popular with users.

Today it's WordPress.

And Slack is doing interesting things with their APIs.

Twitter too, but that got kind of muddied-up.

The best one of all of course is JavaScript, a very bizarre language in a totally underpowered environment that reaches into every nook and cranny of the modern world. It's an awful environment, you'd never design one that worked that way, but the draw of all those users makes up for its sins.

Flickr had a wonderful API, still does, but Stewart left the house before it could really blossom as a community thing. See Slack, above.

Chatting with Brent Schlender the other day, I commented that Steve Jobs' politics and mine are exactly opposite. Jobs was an elitist, all his products were as Doc said in 1997, works of art, to be appreciated for their aesthetics. I am a populist and a plumber. Interesting that this dimension of software is largely unexplored. I hope our species survives long enough to study it.

BTW, when ESR saw XML-RPC he said it was just like Unix. Nicest thing anyone could ever say. When I learned Unix in the mid-late 70s, and studied the source code, I aspired to someday write code like that. So well factored it reads like its own documentation.

Today, I'm mainly concerned with getting some outside-the-silos flow going with people I like to read. If we get (back) there, I will consider it a victory.

London: Why take Heathrow Express?

by Jarrett at HumanTransit.org

HeathrowExpress.svgMy recent visit to London, the first in 19 years, gave me a new appreciation for the dangers of creating express trains to the airport that are useful only to high-paying travelers.

We stayed at Paddington, on the north-west edge of the inner city, because I presumed that the Heathrow Express -- nonstop trains between Paddington and Heathrow Airport every 15-30 minutes -- would help us handle the awkward moves with luggage.  It worked fine for that, but the fare was obscene (well over GBP 20 each way) and the trains were therefore nearly empty.  I should have suspected this from the logo's resemblance to a luxury car hood ornament. 

This appears to be a classic example of an overspecialized transit service -- designed to separate people by fare even though they are all going in the same direction at the same time.  Its based on the assumption that people with money would like to wait longer for a more comfortable service that skips a few stations, rather than use the ordinary Underground line from Heathrow that is far more frequent and runs directly to many more parts of London.  I have similar concerns about overspecialized airport train projects in Toronto, and others proposed elsewhere in the world.  

Quite simply, I'd have been happy to pay half the fare for a train that made a couple of stops, so that a lot more people could get on.  Heathrow Express has achieved a nice sensation of luxury; near-empty trains are always a pleasure, but they also suggest a poor business model.  Heathrow Express will eventually have competition from Crossrail, which will run deeper into London with a few more stops, but which will still be much faster than the old Piccadilly Line from Heathrow.

After all, if people with money refuse to ride the Underground, then why does the Underground contain advertising for first class seats on Emirates?

PiJuice: portable power for your Pi projects

by Helen Lynn

Helen: some Kickstarter campaigns just jump out at you. When I took a look at PiJuice it was obvious it was the real deal – they’ve only gone and sorted out portable power for the Raspberry Pi, with bells on. Their Kickstarter runs until Tuesday, so you’ve got the weekend to jump on board. Here’s Aaron Shaw to tell you more.

I started playing with the Raspberry Pi since the very beginning and after being involved in The MagPi and various other activities I am now fortunate enough to call Raspberry Pi tinkering my “work”. The thing that got me hooked back in 2012 was the hardware and physical computing capability – writing code to do things in real life (probably because of my background in Automotive Engineering) and I still spend a considerable amount of my time just learning new things and playing around with everything the Raspberry Pi has to offer. It has been a fantastic opportunity and I want to share it with as many people as possible.

PiJuice

Around a year ago I met Harry Gee from PiBot and we started by just throwing around our ideas for how we could help to make the Raspberry Pi even better. One of the things that we had both found difficult was creating portable or remote projects – it was of course possible, but it was just a lot harder than it needed to be. This ultimately led us to the idea of making a neat, safe, portable power solution for the Raspberry Pi to allow people to do even more exciting things with their Pi, whilst saving a lot of time and effort in the process.

PiJuice module

We’ve called this the PiJuice and it’s the ultimate product for portable and remote Raspberry Pi projects. The idea with PiJuice was to remove a barrier to entry from portable Pi projects so that beginners and professionals alike could focus on building, making and learning rather than worrying about the complexities of lithium battery charging and other electronics issues, whilst reducing the costs in the process.

 

Maker Kits – Made for Makers

PiJuice is more than just an add-on board. We are passionate about education and are keen to turn PiJuice into a modular project platform – a way to allow people to build their awesome ideas much more quickly and easily.

To kick things off and provide some inspiration we have developed a number of exciting tutorials and projects including a Raspberry Pi games console, a compact camera, a Pocket Pi and more.

Make cool stuff

We are calling these Maker Kits and they are already available to purchase in kit form from our Kickstarter page and are being uploaded as free guides on Instructables.

These guides will soon be turned into high quality step-by-step guides that you can either use with our Maker Kits or to build and make your own.

Free Off-Grid Power To the Pi

Off-grid power

When creating Raspberry Pi projects outdoors we’ve also been interested in using solar power as it is free and renewable. We’ve worked hard to create an efficient and low cost solution that will open up new off-grid and sustainable applications for the Raspberry Pi.

The PiJuice Solar has additional circuitry which adds functionality to enable truly autonomous, self-monitoring operation of the Raspberry Pi – perfect for weather stations, remote camera systems for nature watching and more.

Additionally, we are actively investigating possibilities for affordable wind and thermoelectric power generation with PiJuice Solar for added flexibility.

What would you do with yours?

What would you do with yours?

We are really interested in what you want to do with your own PiJuice. We want to create the projects that appeal to you the most, so please suggest us your ideas in the comments, or on Twitter (@ThePiJuice) using the hashtag #ProjectPiJuice to get our attention. We will turn the best of these into free projects for everyone to enjoy!

We really hope to help as many people as possible create awesome portable Raspberry Pi projects as well as continuing to create beautiful guides for cool projects! We’re currently coming to the closing stages of our Kickstarter and would appreciate any support to help make PiJuice even better – http://pijuice.com.

Old school data journalism from the 1800s

by Nathan Yau

Compensation map

Data journalism is relatively new as a concept, but in practice it has been around for a good while. Scott Klein for ProPublica tells the story of Horace Greeley, an editor for the New York Tribune and a congressman in the mid-1800s. Greely was displeased with a law that specified mileage compensation for travel to the capital, so he found a way to prove his point with data.

Rather than simply opining against it, he conceived and published a data-journalism project that, in form if not in execution, would be very much at home in a newsroom today. He asked one of his reporters, Douglas Howard, a former postal clerk, to use a U.S. Post Office book of mail routes to calculate the shortest path from each congressman's district to the Capitol, and compared those distances with each congressman's mileage reimbursements. On Dec. 22, 1848, with Greeley now simultaneously its editor and a brand new congressman from New York, the Tribune published a story and a table in two columns of agate type. The table listed each congressman by name with the mileage he received, the mileage the postal route would have granted him and the difference in cost between them. "Let no man jump at the conclusion that this excess has been charged and received contrary to law," wrote Greeley in the accompanying text. "The fact is otherwise. The members are all honorable men — if any irrelevant infidel should doubt it, we can silence him by referring to the prefix to their names in the newspapers."

See Greely's results table and article.

So you see, Sea Lion fans, if it’s a Bad Thing that happens largely to women — like Campus Rape and domestic violence — it’s automatically controversial!

There’s no chance that this will work; it can’t be supported rationally and it can’t be administered sanely. As far as I can make out, the plan is to ban trouble-makers (like me) left and right until everything is calm and civil, a plan excused because Gamergate is not terribly important in the great scheme of things.

The problem for Wikipedia is that gender-related issues and controversies are important. Wikipedia stumbles badly on many of them, in part because so much editing is performed by factions, cliques and trolls, and in part because so many Wikipedia editors just aren’t interested in gender beyond looking at pictures of pretty women who have misplaced their clothes.

Because freedom matters

by Doc Searls

After one of myaxiom reluctant visits to Facebook yesterday, I posted this there:

If I were actually the person Facebook advertised to, I would be an impotent, elderly, diabetic, hairy (or hairless) philandering cancer patient, heart attack risk, snoring victim, wannabe business person, gambling and cruise boat addict, and possible IBM Cloud customer in need of business and credit cards I already have.

Sixty-eight likes and dozens of comments followed. Most were from people I know, most of whom were well-known bloggers a decade ago, when blogging was still hot shit. Some were funny (“You’re not?”). Some offered advice (“You should like more interesting stuff”). Some explained how to get along with it (“I’ve always figured the purpose of Internet ads was to remind me what I just bought from Amazon”). One stung: “So much for The Intention Economy.”

So I replied with this:

Great to see ya’ll here. Glad you took the bait. Now for something less fun.

I was told last week by an advertising dude about a company that has increased its revenues by 49% using surveillance-based personalized advertising.The ratio of respondents was 1 in a 1000. The number of times that 1 was exposed to the same personalized ad before clicking on it was 70.

He had read, appreciated and agreed with The Intention Economy, and he told me I would hate to hear that advertising success story. He was correct. I did.

I also hate that nearly all the readers all of us ever had on our own blogs are now here. Howdy.

Relatively speaking, writing on my own blog, which averages zero comments from dozens of readers (there used to be many thousands), seems a waste. Wanna write short? Do it in Facebook or Twitter. Wanna write long? Do it in Medium. Wanna write on your own DIY publication? Knock yourself out.

And, because the bloggers among us have already done that, we’re here.

So let’s face it: the leverage of DIY is going down. Want readers, listeners or viewers? Hey, it’s a free market. Choose your captor.

I’ve been working all my adult life toward making people independent, and proving that personal independence is good for business as well as for hacking and other sources of pleasure and productivity. But I wonder whether or not most people, including all of us here, would rather operate in captivity. Hey, it’s where everybody else is. Why not?

Here’s why. It’s the good ship Axiom: http://pixar.wikia.com/Axiom . Think about it.

Earth is the Net. It’s still ours: http://cluetrain.com/newclues. See you back home.

That’s where we are now.

Rekord: 2014 erstmals eine Milliarde Smartphones verkauft

by Heike Scholz
phones india

Das letzte Quartal 2014 war mit 35 Prozent Wachstum gegenüber dem Vorjahr eines der erfolgreichsten. Das Wettrennen zwischen iOS und Android geht weiter, genau so wie Microsoft weiterhin keine relevante Rolle spielt.

Diese Zahlen liefert der aktuelle Bericht von BI Intelligence. Mit dem kräftigen Schub aus dem vierten Quartal 2014 wurden erstmalig eine Milliarde Smartphones in einem Jahr verkauft.Smartphones

Auch für die kommenden Jahre werden noch jährliche Wachstumsraten von 16 Prozent erwartet, so dass im Jahr 2020 3,4 Milliarden Geräte verkauft werden.

Durch günstige Smartphones werden die Feature Phones zunehmend ersetzt. Schon heute sind von allen weltweit verkauften Mobiltelefonen nur noch 25 Prozent Feature Phones.

Dieses Wachstum wird in erster Linie von den Schwellenländern getrieben. Wobei der chinesische Markt sich der Marktsättigung nähert und nur noch mit acht Prozent pro Jahr wächst. Die höchsten Wachstumsraten verzeichnet Indien mit 31 Prozent.

Apple konnte mit dem iPhone 6 Terrain gut machen und konnte im vierten Quartal 2014 mit einem Zuwachs von 46 Prozent einen um acht Prozentpunkte höheren Anteil auf sich vereinen als im Vorjahr. Dieses Wachstum ging vorrangig zu Lasten von Samsung, deren Verkäufe in diesem Quartal um sieben Prozent fielen.

How to stand (at your desk)

by Mark Lukach

You’ve heard about the risks of sitting all day long. If not here, then here, here, here, and here. The studies are everywhere, and the verdict is in: We should not spend all day sitting, even if we make time to exercise. It’s not how our bodies are supposed to operate.

So, you want to take the plunge for a standing desk? Here’s our advice on how to go about doing that.

Ease into it, and start cheap

Don’t rush out to buy a top-of-the-line, thousand-dollar desk that moves up and down with the push of a button. Save that for later, once you’re really into this. For now, start small. Any little bit of standing that you do will be an improvement over sitting all day long.

Here are a few small things that you can do without even creating a standing desk. They might be seem silly, but they’re certainly better than sitting for eight hours straight.

  • Commit to doing a certain work task while standing, every time you do it. For example, take all of your calls while standing. Or, if you read at work, stand while reading reports or articles. Neither of these require a standing desk.
  • Take standing breaks during meetings. I’ve found that this actually helps me stay focused, too.
  • Drink more water. This is not only healthy, but also a way to keep you moving–by forcing you to get up to refill your glass, and go to the bathroom. All that walking time is good time.

Enough foreplay, I want to stand

Cheesy tips aside, this is about actually standing while you’re at your computer, not just peeing more during the day.

Again, start small. The best first steps are to set realistic goals and keep your desk cheap. If you try to stand too much right off the bat, you’re probably not going to like it, and you might not stick with it. You should also figure out your own patterns before you rush into spending more money than you need to.

A good first goal is to stand for one hour a day while at work.
A good first goal is to stand for one hour a day while at work. And do it in small shifts–20 minutes here, 20 minutes there. Do that for the first week. Then increase it to two hours. Gradually work your way up until you find a standing amount that feels right for you. Even the most ambitious standers don’t stand for the full day, usually maxing out at about 80 percent of the workday.

Since you’ll start by moving up and down a lot, you’ll eventually want a desk that adjusts easily. While it might be tempting to go for the $22 IKEA Hack, that, along with many other cheap standing desks, is a fixed-height desk. These can work as an introduction to standing–my sister, the person who got me into standing, stacked boxes on her desk for eight months. But once you’re serious, you need something that can easily adjust. It’s a huge deterrent to standing if it takes you 15 minutes to set up your desk, and then another 15 to take it apart each day. That is why we recommend the Ergo Depot Jarvis as the best adjustable standing desk, and the Kangaroo Pro Junior as the best way to convert your current desk to a standing desk. Both are “affordable” (compared with competitors), reliable, extremely functional, and good looking. You can read our full review of standing desks for a better understanding of the options that are out there, and why we like the Jarvis and the Kangaroo Pro Junior.

It’s important to put your keyboard and monitor at the appropriate heights. If you don’t, you might cramp your shoulders, back, or neck by craning. To determine your ideal height for your monitor and keyboard, stand up straight and bend your elbows so that your forearms are parallel to the ground. Wherever your hands are, that’s the ideal height for your keyboard. And whatever is at eye level, that is your ideal monitor level. Create your desk around those dimensions.

You will quickly realize that laptops are not conducive to standing, because the keyboard and monitor are at almost the exact same level. It kind of makes sense–the name is “lap”top after all, which implies sitting. The easy fix for this is to purchase a separate keyboard, which isn’t very expensive at all, but will make your desk much more ergonomic by separating the keyboard from the monitor. Or, you could purchase a separate monitor, such as our favorite, the Dell UltraSharp U2412M.

Mastering the fine details

Once you’re standing an hour or two a day, you’ll notice that there are a few nuanced touches that can make a huge difference.

Standing in place all day is not that good for you either. With all of these studies showing how bad it is to stand, some doctors have looked at the harm of too much standing, and have concluded that static standing, without any weight shift or movement, can lead to increased varicose veins, which are pretty gross.

To combat this, set up your desk near something that you can lean on from time to time, which will help you shift your weight around. And also, try to get into the habit of swaying or rocking–nothing drastic here, but enough to get your weight moving around a little bit.

Get comfy shoes or, even better, go barefoot. If it’s not going to freak anyone out, go ahead and take off your shoes. But if you need footwear, keep a comfy pair of flats at the office that you can change into for standing.

Get a standing mat. They are pretty cheap and can make a huge difference in your comfort throughout the day, especially when you start standing for extended stretches of time. We have a full guide to standing mats, where we explain in depth the benefits of a mat, and why comfy shoes alone aren’t enough. Our favorite is the WellnessMats Original.

Put music on. It’ll get you dancing, which is good! You’ll shift your weight more and avoid that problem of standing in the exact same place all day.

Take breaks. This isn’t a race. This is a behavior that ultimately you are hoping to adapt to for the long haul, preferably the remainder of your working life. Give yourself a break from time to time. Standing all day is harder than you’d think. Make it easy on yourself to enjoy standing.

For the advanced stander, try a treadmill desk. That’s guaranteed to keep you moving. AJ Jacobs wrote an entire book at a treadmill desk, and he speculates that he logged about 1,200 miles in the process. Or, you can work on any variety of balancing boards. I work at my desk while balancing on an Indo Board. I’m often on there for three to five hours a day. It feels amazing.

Otherwise, it’s just standing. Hard to overthink it.

Check out our guide with our recommendations for the best standing desk. And, hey, try standing up while you’re reading it.

Hover Stories: Frederick Van Johnson from This Week In Photo

by Michael Keshen

Frederick-Van-Johnson

When Frederick Van Johnson enlisted as a photographer in the United States Air Force’s Combat Camera unit in 1988, he developed an affinity for photography that would change the course of his life forever. He would go on to work at some of the biggest companies in tech – including Yahoo!, Adobe and Apple – helping to shape their photography products that we all know and love today.

As great as these experiences were, they were all preparation for his biggest endeavour to date: This Week In Photo. Part podcast, part network, part training center, TWiP is the go-to source for aspiring and professional photographers looking to both develop and refine their craft. In turn, Frederick juggles multiple roles: entrepreneur, marketer, photographer, speaker and countless other responsibilities that come with running your own business.

“It’s going well but I have more grey hairs because of all of this. But other than that it’s really fun,” he jokes.

When we discovered that Frederick uses Hover to manage his many domain names, we were of course excited and wanted to learn more about his story. We recently sat down with him – or rather video chatted with him from his iconic home office seen in his video podcasts – to learn more about how he got to where he is today, as well as the exciting places that he’s heading.

Getting Started

Airman_Johnson

Frederick got his first taste of photography in the U.S. Air Force where he photographed, directed and designed multimedia projects for military officials. His nearly 8 year tour of duty enabled him to really get to know his way around a camera, and sparked a passion for photography that would only grow as the years went on.

“That’s where I learned photography, learned to love light, and got bitten by that creative photographic bug,” he reflects.

After leaving the military in 1996, Frederick relocated to Silicon Valley. His first job was at the San Jose Mercury News, where he became the newspaper’s Chief Multimedia Producer. It was here that he learned more about the rapidly growing tech industry, which began to capture his fascination.

“Working at the newspaper I saw: a) the decline of newspapers, and; b) we were reporting on these crazy tech companies that were doing all this cool stuff,” he explains. “I wanted to go and join one of those companies. I wanted to be making tech news, instead of helping to report on it.’”

Working in the Valley

frederick-at-adobe

The next chapter in Frederick’s career consisted of establishing himself as a prominent marketer in the tech industry.

His first position was at Yahoo! where from 1998-2002 he was initially a Senior Producer, and was responsible for the company’s entry into mobile content delivery. Specifically, he started what later became Yahoo! Mobile. Later, he served as Creative Director and on-air host for Yahoo!’s media property Yahoo! FinanceVision. There, along with being on-air talent, he focused on the look and feel of the company’s streaming video efforts.

Next, he moved over to Apple where he held the role of Product Marketing Manager for the popular iPhoto photo management software. Then he landed at Adobe in 2007, and accepted a position Sr. Product Marketing Manager for the professional photography market segment, and Adobe Photoshop Lightroom.

In 2009, after a year and a half at Adobe, Frederick received the first major blow to his career. “Adobe was one of the first companies during the economic slow-down to have a massive layoff — 800 people in one day!” he recalls. “It was just like boom, 800 gone, everyone was carrying boxes and crying, it was a really emotional day.”

Though this was quite shocking, it ended up being a blessing in disguise. While he was busy building a successful career as a marketer, he had been neglecting his true passion — photography. “I was seeing myself moving further and further away from my creative roots and photography,” he explains, “so I decided it was time to move back into photography.

This Week In Photo

fred_on_radio

It was around this time a few of his friends started a photography podcast called This Week In Photo (TWiP). When Frederick found himself with some free time on his hands, he realized that the time was right to rekindle his love of photography. So, he joined TWiP as a co-host, and would eventually take over and drive the operation altogether.

Regarding how his mind works, he says, “it’s kind of like a Reese’s Peanut Butter Cup, where you have the chocolate and the peanut butter together. I had marketing and photography skills, and I wondered, how could I put these together to make something that’s a viable business as well as help people.’ So over the years I grew TWiP from being just a hobby podcast to a profitable business and media property to be reckoned with!”

Under Frederick’s helm, TWiP has evolved from a single podcast to a network of podcasts covering the diverse world of photography. In total they have around 25 staff, and have an additional 7 new shows slated for release within the next 6-7 months.

“The This Week In Photo site is kind of like an ‘incubator’, because many of  the shows are new and full of promise,” he explains, “and as they grow, they’ll get their own legs and break off to become separate properties themselves, each with its own community of fans, advertisers, content, etc — away from the mothership.”

Over the years, Frederick has hosted over 400 shows that have been listened to millions times all over the world, and he has interviewed countless photographers and industry leaders. Along with his frequent speaking engagements and his seat on the Brooks Institute’s Board of Trustees, this has all cumulated into establishing himself as a powerful thought leader in the photography world – something that he is both surprised and honoured by.

“Podcasting is kind of a weird off-shoot of celebrity,” he explains. “It’s not real ‘Hollywood’ celebrity. It’s an accessible kind of celebrity, because people know that you’re just a normal person, and you are using the exact same gear that they may have. I’m just another guy that you happen to have heard repeatedly. But that repetition somehow equals importance. It’s an interesting nuance.”

Why He Chose Hover

While we had Frederick’s attention, we chose to be a little selfish and ask why he uses Hover for all of his domain names. Luckily he didn’t mind, and in fact had many great things to say about us.

“I chose Hover because the company struck me as the ‘Apple’ of domain registration in terms of the transparency and simplicity of how it all worked together,” he reflects. “Initially, I had domains in several different places, and if I recall correctly Hover had a valet service that basically facilitated moving my other domains over to Hover for me. And I was like ‘hallelujah!’”

Coincidentally, he had even been recommending us to his sister that very morning.

“This morning, I received an email from you guys about some new top-level domains that are becoming available,” he explains. “My sister has a cosmetology business and I explained to her that she should register a .CARE domain name for her business. She said ‘I have no idea how to register that, tell my nephew to do it!’ and I said, ‘no, just go to hover.com and just do it’ and I sent her the link and she’s doing it right now!”

“I wouldn’t have felt comfortable sending her to some other services. Instead, I likely would have said, ‘you know what, let me just do it for you.’ But with Hover, I feel confident sending my sister over to register her domain.’”

Need a new website? Search for a domain name ending with .COM, .PICS, .PHOTOGRAPHY or any of our other 300+ top-level domains:

The Power of Reuse: Wikipedia in Action

by Stephen Downes
Summary of a panel at the Hewlette Grantees' Conference. Errors are again my own.

Pete Forsyth, Wiki Strategies
(See also his blog post with resources for this panel at http://wikistrategies.net/oer-wikipedia-getting-started/ )

In the past we've been saying that it's important to the field of OER to improve content. But really, it's about teaching and learning. So what is it about Wikipedia that is an opportunity for learning?

Jeanette Lee, the Cambridge School of Weston

We are integrating technology in the classroom, and students are always asking whether they can use Wikipedia. We have a handout we created on how to use Wikipedia. One of the students wanted to use the message box from an article, and we had a conversation about how to use it. So, students are using Wikipedia and the question is how to integrate it.

Amin Azzam, UCSF

The peer review process has sort of a stranglehold on academic advancement, but they were interested in partnering with Wikipedia such that if an author updated an article it might be counted as a publication. The meeting on this was just yesterday.

The medical students all go to Wikipedia first when they go o look something up, because it's written in a way they can understand, and then they go to a more reliable source. So then someone suggested that students could contribute to Wikipedia.

Dan Cook, Wiki Strategies

I'm a voracious consumer of Wikipedia. My work is both as a journalist and as a consultant. This week for example there was the experience of going from an article being marked for deletion to the potential removal of the banner altogether. I have these experiences pretty much on a daily basis.

I was part of the 'new journalism' when it was coined in the 80s. Secret sources and fights with the editors and all that. But now Wikipedia is the new journalism of today; leave your ego at the door, don;t use any modifiers, we don't want any spin. But it's a hard place for traditional journalists to work; we have to unlearn everything we learned about journalism.

Jeanette

I compare Wikipedia articles to an expository essay, which students have to learn. So getting them to understand that Wikipedia articles have structure, they have references, etc. So the idea is making the use of Wikipedia in academia transparent. People are using it, they're just using it quietly. It was about how to get a language to move between Wikipedia articles and the more traditional essay.

A funny statistic from Pew, from February: 90 percent of AP and National Writing teachers find information online for their classes; 90 percent use Google, 87% use Wikipedia, but they discourage their students from using it. So there is this contradiction. So we need to get out in front and deal with this contradiction. We need a PR campaign or something, so people know it is legitimate to use in their classrooms.

Amin: Yes, 87-93% of medical students admits to using it.

Dan: If you could just get them to take the next step and look at their sources!

Jeanette: yes, that's what we want them to do, it's a great skill to develop.

Amin: there's roughly 26K articles in the medical field, but a lot of them have room for improvement. One thing wwith my students is they're in the final year of med school, so they can contribute, but they haven't lost the ability to speak English yet.

Pete: the articles I contributed to most were on topics I was learning about. Also, Amin mentioned 'English Wikipedia'. This points to a way where Wikipedia and OER have a lost of aspirations in common. (Reads from letter mourning the death of Babu Gi, from Kerala, and commemorating his contributions).

Amin: discusses the translation of medical articles into other languages. Wikipedia has an initiative called 'Data Zero' to give access to Wikipedia content for free. To me this is a no-brainer. (See http://en.wikipedia.org/wiki/Wikipedia_Zero )

Jeanette: opportunities for OER to learn from Wikipedia - I don't have students contribute to Wikipedia, but I do have students use materials from Wikipedia and OER Commons - I do hand over a lot of content to students, and then they create the content that everyone uses. I give them the option: either I lecture, or you do this project. Usually they choose the project. And they know that everybody will be using the material for understanding the text. I view Wikipedia as part of the OER community, and it's a way for them to use Wikipedia even if they can't contribute (they're just high school students, I would have too many permissions I have to fill out).

Amin: there's a source of med information by students for students called 'Up To Date', it's called 'crack for medical students', but it's subscription, and they don't realize how much the school has to pay.

Pete: where do students become ready to contribute to Wikipedia?

Jeanette: I think definitely there are high school students ready for that.

Amin: it's a question of what fraction of school work is contributing. For example in my class they have peer review. They need this support.

Jeanette: some projects are individual and some are group. Anything that's a presentation for the class, they grade it, I don't grade it.

Pete: I see this as a new journalism and I would like to see training begin in the classroom, so they don't get the bad habits I got. When will students work on Wikipedia?

Jeanette: there are concerns about privacy, that's the barrier. I do think it would be a hard sell for some districts. Showing districts how they can use Wikipedia would be much easier.

Amin: my students had to create user names, so we could track their contribution. They began with non-descriptive user names, but eventually made it clear they were future doctors.

Pete: there is this culture of anonymity in Wikipedia. It's a major part of the ethos. But then there's the potential for conflict of interest; we don't want the chief of Enron writing the article.

Dan: why did reporters have bylines? So they could be held accountable. Journalists especially need to have user names that are transparent and they should describe themselves in a transparent way. There needs to be a high level there. When I search to see if an article is credible, I don't like seeing that the author is anonymous. Wikipedians will have to grapple with this.

Amin: the concept of anonymity almost doesn't exist any more. They have their Facebook pages, they scrub them clean before going into med school.

Dan: I think it's people in my generation, they don't want to give up their social security numbers, etc.

Jeanette: developing people who are comfortable as Wikipedia users, as they go into college, they're used to working in that kind of environment.

Amin: my future students will be already equipped knowing how to be contributors.

Q: there are now things where you can remix in the OER space; but in schools there is this top-down ethic about who is eligible to do that (it has to be curriculum specialists, etc).

Amin: I consider the medical librarian an equal partner in the course, and the Wikipedia contributors to be equal partners. There's no way for any of us top be experts in everything. It takes a village.

Pete: Wikipedia and OER are characterozed by people coming together in ways that were never anticipated, and saying to previous generations, we're not waiting around for you any more. We want to address content gaps. Etc. The sort of thing that doesn't work well in that crowd-sourced way. Eg. the small number of contributions by women.

Q. Pete said to me, the first thing they do after you tell them about OER, they go to Google and search for it, and find the article on Wikipedia. Do you care about what they're reading? Do you feel this is your responsibility? What ought we be doing in this community?

Pete: it's not an easy process, it doesn't have easy boundaries, you have to decide what's important for yourself, and you have to think about how much you can get in, how to work with other people.

Amin: Wikipedia is not a democracy, it's a do-ocracy.

Q: it seems to be impermanent, in the beginning, anything we thought was of value was not surviving. But the value is where you should be participating. It does compel participation. We made a lot of mistakes, but most of our articles are surviving now; it's about participating in the community. Our students talk about 'surviving the Wikipedia process'. But that's the strength of Wikipedia.

Pete: we see this dynamic a lot. People contribute an article and it's highly imperfect, just what was in the newspaper. And then a few years later an expert comes along, and says there's all these errors. And I say to them, "when were you going to do this?" When would you write the article, without having seen all the errors.

Dan: I tell people, "go to the talk pages". That's where you can see the process at work.

Q: does it make sense to have a Wikimedian-in-residence in OER?

Amin: Brillian idea.

Jeanette: I totally agree with that. And Wikipedia has done a good job partnering with universities. Such a person could encourage partnering with districts.

Q: question was more whether it would conflict with the Wiki education foundation?

Pete: no it would not at all. I know most of those people, I think there would be delight.

Periscope:

The new live-streaming mobile app from Twitter. As an early investor (before the sale to Twitter, of course), I’ve been testing the service for months and I cannot wait to see what the world does with it now that it’s out there. 

So much time, care, and thoughtfulness went into this one.

Software Aesthetics: Cuteness

Exploring fringes of software aesthetics, I’ve been reading up on things that are not quite beautiful. I came across this in a book review by Adam Kirsch in next month’s Atlantic:

Niceness without goodness is cuteness.

This makes a certain sense; it explains, for example, why a toddler can easily be cute but is seldom beautiful. “Goodness” here is not a moral judgment, or not just a moral judgment: an horse with a hat might be cute, but a beautiful horse is a horse doing what horses do – running gracefully through a meadow, say.

How would this work with software?

We look at a clever Perl one-liner, decipher it’s meaning, and exclaim “Nice!” But one-liners seldom do much good: even when they do something useful, it’s probably better to use a few lines to explain what you intend. Perl one-liners are cute.

Gratuitous user interface polish does little or no actual good; it’s an expense, and it seldom produces much benefit. Often, this year’s marvel may be actively pernicious in a minute or two: remember Cordovan leather backgrounds? Gratuitous polish is cute.

Under the hood, it’s entirely possible to use language features in strange and esoteric ways. You can be make C++ feel like a functional language. You can make C++ feel like Smalltalk. You can write little interpreters in C++ and do the real work in your own variant of LISP. Sometimes, this is elegant; often, it’s merely playing cute.

Games and fictions sometimes drop the mask (or the fourth wall) to attempt an arch and knowing address to the player. We’re in the middle of a complex and challenging city simulation, and suddenly notice that the factories all have silly names and make silly products, or have in-joke references to industry insiders. Archness in games and fiction is cute.

Almost all codewerk is cute.

Brent Simmons hit this nail on the head when he wrote about the problems of splitting classes that are too large and do too much into smaller, more focused objects. If you do this intelligently, you get better code. If you get carried away, you get a basket of bunny classes. Bunny classes are cute.

Constructing Symbols and Collective Identity

by Richard Millington

Trace the history of almost any flag.

Clearly the colours and design weren’t put together by accident. They reflect something about the country’s history and its members. The challenge isn’t to create a cool design, but to accurately reflect the history of those the flag represents.

At our SPRINT USA workshop, I asked all 20 groups of 5 people to design themselves a flag. It was a difficult assignment. They have a blank page and four members they've just met.

Most groups resorted to something funny, it's the safe option. 

Symbols help create a sense of collective identity. The best symbols reflect the history of the group. It's hard to do a symbol at the beginning, because it has nothing about the group history to reflect. Far better to wait a year or so and then introduce symbols which best reflect the history of the group. 

Next time we’ll do a flag at the end. I suspect even with a day’s history they’ll be able to put together a flag much easier. We can even let members offer their ideas and vote on them too.

Facebook F8 – Family matters.

Facebook is creating a family of products to address Digital Life.

  • Facebook has opened what I consider to be the most important season of industry meetings when it comes to really understanding the action and the money in the consumer electronics industry.
  • Between now and mid-June Facebook, Microsoft, Google and Apple will hold their developer conferences where they will unveil the innovations with which they intend to strengthen their ecosystems.
  • Users do not pay crazy prices for iPhones or let Google into every aspect of their lives for no reason.
  • They do so because they want access to the Digital Life services that these companies deliver and for that they are willing to pay in coin or in data.
  • In fact so commoditised has become the hardware that I would argue that over 90% of the mobile industries profits are in fact generated by people paying to access an ecosystem not a device.
  • Facebook kicked off the season with F8 where it is presenting to 2,000 developers how it intends to develop the Facebook user experience.
  • Facebook messenger has been a colossal success since it was stripped out of the larger Facebook app. and has now passed 600m users.
  • Facebook intends to build on this success and its offering is developing into a family of services which I presume will eventually cover most of the activities that users carry out on their phones.
  • To this end the big announcement of the day was that Messenger will now become a platform upon which developers can innovate.
  • It is starting small, with innovation limited to entertaining ways in which to communicate over the messenger system, but it is clear that the plans are this to evolve.
  • Facebook also announced the ability to communicate with businesses within the messenger app. neatly moving the system into e-commerce which is the single fastest growing activity on mobile devices albeit from a low base.
  • In effect, messenger is following the trajectory of Line and WeChat in creating its own platform from which it can offer value to users and keep them using its services for as long as possible.
  • I suspect that over time all of Facebook’s existing properties will be evolved to allow more developer innovation and to offer a more complete set of services.
  • Furthermore, I would expect them to end up working much more closely with each other so that users feel they are living in one place just with multiple rooms.
  • This is exactly what Facebook needs to do as its long term growth depends on users doing more than just social networking and messaging on Facebook.
  • Great coverage of Digital Life will mean greater relevance of advertisements and more time spent by users giving a much greater revenue opportunity.
  • This will have a significant impact on revenues but there is a long way to go before this revenue shows up in the numbers.
  • The first problem to solve is the awkward situation that exists with WhatsApp.
  • This asset is in the books at $19bn (1,357x 2014A Price / Sales) but Metcalf’s law of networking indicates that there is a lot of value to be gained if the two can be put seamlessly together.
  • This is badly needed if Facebook is to escape a massive goodwill write down as WhatsApp. Delivers virtually no tangible revenues of its own.
  • This is why WhatsApp. must become part of the Facebook family and I think that over the next year or two, we will see this become a reality.
  • Facebook announced nothing particularly new or revolutionary at its developer conference but it did announce what is needed to keep its revenue growth going over the medium term.
  • Its biggest asset is its 1.3bn MaUs and the 600m who regularly user Facebook and Messenger.
  • This gives it a massive advantage over its smaller competitors who will need to develop geographic or functionality niches to keep their users on board.
  • Facebook is slowly becoming an ecosystem but I need to see a lot more of the pie covered before I can be comfortable that it has arrived.
