Mobile service in the UK is cheaper than in the US

Minh Uong
New York Times
We've looked at the bad deal US landline Internet users get compared to places like Korea, Sweden, Japan or Latvia. (The list could be longer). How about mobile connectivity?

The New York Times just published a short article comparing the price charged by UK Cellular company UK Three (UK3) to that of Verizon in the US. The article compared prices for a two year contract with a subsidised Apple 5s phone.

UK3's price in this example is over $40 less than Verizon's. Furthermore, UK3 allows unlimited data transfer while Verizon has a 2 GB per month usage cap. Since UK3 is a low-cost carrier, I checked the prices of Vodafone accounts in the UK. A 3G Vodafone account with a 2 GB cap costs $72.31 per month. A 4G plan with a 4 GB cap is $79.60.

The author of the post cites one significant difference in explaining the price differences between the two nations:
Britain has forced companies to lease their networks to competitors at cost. The United States has not, allowing a formidable barrier against competitors.
The US Congress tried to spur competition in a similar manner with the Telecommunication Act of 1996, but the incumbent operators and their lobbyists defeated that attempt in courts and state houses.

William Kennard, who, as chairman of the United States Federal Communication from 1997-2001, was charged with implementing the Telecommunications Act, stated near the end of his term that “all too often companies work to change the regulations, instead of working to change the market,” and spoke of “regulatory capitalism” in which “companies invest in lawyers, lobbyists and politicians, instead of plant, people and customer service.” He went on to remark that regulation is “too often used as a shield, to protect the status quo from new competition -- often in the form of smaller, hungrier competitors -- and too infrequently as a sword -- to cut a pathway for new competitors to compete by creating new networks and services.”

Who will be first to capture an Amazon package-delivery drone and other intriguing, drone-related questions

Check out the drone zoning illustrations on
Jacob Kastrenakesget's post.
I live in the flight path of a small airport and am bothered from time to time by the noise of planes landing. The folks on the take-off side have a worse noise problem. A few years ago, a small plane crashed on a house while landing at the airport. There seem to be no restrictions on small aircraft flying over my neighborhood.

This post by Jacob Kastrenakesget raises all sorts of difficult and intriguing drone-regulation questions that will arise when they are ubiquitous:
  • Do we need 3-D "zoning" laws?
  • Do we need privacy laws?
  • How could privacy intrusions be detected and the laws enforced?
  • Will we have automated detection and identification of drones?
  • Will we have automated anti aircraft weapons?
  • Who will be responsible for damage caused by crashes?
  • Will there be design safety regulations for drones?
  • What about drone-jackers?
  • Who will be first to capture an Amazon package-delivery drone?

Is FCC Chairman Tom Wheeler a sheep in wolf's clothing?

John Oliver wonders whether Tom Wheeler is
a dingo, but maybe he's a sheep.
President Obama appointed Tom Wheeler, who had headed national organizations representing the interests of the cable and wireless telephone industries and lobbied on their behalf, as FCC Chairman.

Cynics (and realists) saw that as a payoff for the ISP industry. Comedian John Oliver characterized it as "the equivalent of needing a baby sitter and hiring a dingo."

But, maybe Mr. Wheeler is not in the ISP's pocket after all.
  • He was an invited expert by the The President's Council of Advisers on Science and Technology, which issued a report calling for the use of smart radios and sharing federal spectrum. The executive order which followed cannot have pleased Wheeler's pals at AT&T who like exclusive spectrum licenses.
  • When asked to comment on John Oliver's comedy sketch, he said it was good that the public was taking an interest in net neutrality and the ISP industry and denied that he was a dingo.
  • He has spoken out against state laws that keep local governments from providing Internet connectivity.
  • More recently, he has responded to requests by legislators urging the FCC to take action against those restrictive laws, saying that laws restricting community broadband "have the effect of limiting competition in those areas, contrary to almost two decades bipartisan federal communications policy that is focused on encouraging competition" and acknowledging that "state laws that directly conflict with critical federal laws and policy may be subject to preemption in appropriate circumstances." Again, not something his ISP friends or politicians receiving donations from them want to hear.
Actions speak louder than words -- time will tell if he is a captive of the ISP industry or a sheep in wolf's clothing.

update 8/20/2014

Perhaps Tom Wheeler has decided to shift his attention from net neutrality and Internet fast lanes to local broadband networks. (It seems to me that the latter is a more important issue -- broadband competition is severely lacking in the US and the cost of fixing the blockage that is fueling the net neutrality debate between Netflix and the large ISP is small).

Regardless, a battle seems to be brewing over the right of states to restrict municipal broadband.

Matthew Berry, chief of staff to Republican FCC Commissioner Ajit Pai, argued that the FCC has no authority to invalidate state laws governing local broadband networks in a speech to the National Conference of State Legislatures. He evidently sees it as a states rights issue.

It would be nice to think that Mr. Pai and the other commissioners would decide this issue on the basis of broadband competition and investment rather than partisan politics and campaign contributions. Who is the FCC's constituency -- the ISP industry or the companies providing Internet services and the public which consumes them?

Unfortunately, I bet that even if Mr. Wheeler prevails, this question will be tied up in court until the next presidential election. If that is the case, folks like Google, Facebook and John Oliver better make Internet policy a major campaign issue.

IBM's "TrueNorth" neural net chips -- increased density and decreased power consumption will lead to surprising applications.

Big Data led to qualitative improvement in search -- will Big Neural Nets lead to qualitative improvement in artificial intelligence?

The field of artificial intelligence (AI) has two historical roots, dating from the 1950s. The first is information processing models like the chess playing program of Newell, Simon and Shaw, who sought to understand how people did things like play chess by interviewing experts, then programming computers to emulate them.

Herbert Simon and Alan Newell asked chess
experts to think out loud while playing and wrote
programs that used the same heuristics.

The second branch of AI was exemplified by the self-organizing neural networks of researchers like Clark and Farley, who sought to build programs that could learn to recognize patterns by emulating the neurons of a brain. For example, their programs could learn to discriminate between horizontal and vertical images.


(For a lot more on the history of AI, see The Quest for Artificial Intelligence, a History of Ideas and Achievements by Nils Nilsson).

We've come a long way since then, and neural nets have been applied to many "subconscious" pattern recognition problems like speech and character recognition, robot control and spotting cats in images. The logical, algorithmic approach to AI has led to expert systems that emulate conscious thinking processes. IBM AI researchers characterize the difference by saying traditional AI programs are left-brained and neural nets are right-brained. Their goal is to create holistic systems that combine both approaches.


Those same IBM researchers have announced a dramatic improvement in neural net hardware -- they have sharply reduced the size and, equally important, the power requirements of simulated neurons and synapses.


The IBM researchers are able to tile their "TrueNorth" chips to create larger systems, as shown here:


Their next goal is a 4,096 chip system with 4 billion neurons and 1 trillion synapses while consuming ~4kW of power.

That is still not comparable to a human brain, which has roughly 86 billion neurons and 10^14–10^15 and consumes only 20-40 watts of power, and even if they could build a system of comparable complexity, it would not be a brain -- it would be a system inspired by the architecture of the brain.

We will not be able to follow the "reasoning" of neural nets as we can the descendents of early chess-playing programs, but, if they succeed, we will be surprised by the performance and applications of systems containing massive, low-cost, low-power neural nets.

The White House forms USDS and 18F to improve e-government.

The government has formed two new IT organizations in response to the HealthCare.Gov fiasco -- was HealthCare.Gov a blessing in disguise?

The White House just launched the U.S. Digital Service (USDS), headed by Mickey Dickerson, who led the team that bailed out the troubled HealthCare.Gov Web site and earlier worked on President Obama's campaign.

USDS is a management consulting firm for federal agencies, but they do not sound like typical management consultants. They are young technologists and entrepreneurs from startups, Internet companies and and e-government projects. I'm not sure, but I bet none are Harvard MBAs. (Maybe a few from Stanford).

USDS favors lean startup methods, open source and agile development by small teams. They seem more like folks who wear t-shirts to work than wear suits -- reminiscent of an earlier group of young people the government found to develop the ARPAnet.

This list of "plays" from their "playbook" gives you an idea of their development and management style:

You can see more (and comment) on the the playbook here.

USDS will complement 18F, a government agency that was formed last March. (Their office is at the corner of F and 18th in Washington). Both groups are largely staffed by former Presidential Innovation Fellows and they have a common point of view. Unlike USDS, 18F actually builds tools and implements government systems. I am sure they will work closely together.

President Roosevelt (radio) and Kennedy (TV) were leaders at using new commuication media and President Obama was the first succesful Internet campaigner. Now he hopes to modernize government IT -- he might be remembered as the Internet President.

-----
Update 8/13/2014

USDS is also offering suggestions for addressing problems with the federal procurement process that leads to IT failures like HealthCare.Gov -- the TechFAR Handbook, which highlights the flexibilities in the Federal Acquisition Regulation that can help agencies implement “plays” from the Digital Services Playbook that would be accomplished with acquisition support — with a particular focus on how to use contractors to support an iterative, customer-driven software development process, as is routinely done in the private sector.

-----
Update
8/23/2014

18F is building tools and expanding -- hacking bureaucracy and promoting open source. They've reduced the hiring cycle from six to nine months to six to eight weeks by making Schedule A hires, which are limited to four years. That is sufficient for people used to working in "startup mode" and reminiscent of the grad students who worked on short-term grants to build the ARPANet and NSFnet.

An estimate of Netflix's "fast lane" fee to Comcast -- $.86 per subscriber per month

Netflix, ISPs and transit providers blame each other for poor Internet performance. The public would be well served by transparency -- seeing the cost and traffic data underlying the debates on network neutrality and, more important, the high cost of US Internet service and lagging investment in US Internet infrastructure.

Generator Research has estimated the cost of delivering Netflix content in their report Over-the-Top Television, 2014, which includes an estimate of the cost to Netflix and Comcast of delivering Netflix content and of the fee Netflix is paying Comcast.

They begin by noting that Netflix's total cost of revenue (including content, delivery and other costs) was reported as $1,849 million in 2013 and they had an average of 29 million US subscribers for the year, then make the following assumptions:
  • The cost of content is 80% of the total cost.
  • The cost of delivery is 80% of the remaining cost.
  • 75% of delivery cost is in the access network, 25% in the ISP network.
  • Comcast earns $30 per month per subscriber, $24 of which is as a result of delivering Netflix traffic.
  • 80% of Comcast traffic is due to Netflix.
Based on this, they estimate the total cost of delivering Netflix content as $2 per subscriber per month, with Netflix paying $.86 and Comcast $1.15. Assuming they split the cost in proportion to their monthly revenue ($7.99 for Netflix and $24 for Comcast), Generator guesses that Netflix's fee to Comcast is around $.28 per month per subscriber -- less than 5% pf the cost of a subscription. (Compare that to my ISP increasing my bill by 5-10% every year because, as a monopoly provider, they can).

Generator's conclusion is based upon several assumptions, which you may question, but it is a starting point in estimating cost of content delivery.

-----
Update 8/26/2014

Whatever the marginal cost, someone has to pay for investment in Internet infrastructure. Netflix CEO Reed Hastings says it would cost the ISPs very little to upgrade in order to provide the level of service they advertise to their customers.
It's worth noting that Netflix connects directly with hundreds of ISPs globally, and 99 percent of those agreements don't involve access fees. It is only a handful of the largest U.S. ISPs, which control the majority of consumer connections, demanding this toll. Why would more profitable, larger companies charge for connections and capacity that smaller companies provide for free? Because they can.
Hastings' post is one in a series on How to Save the Net running at Wired.com.

A visit to podcast Mecca -- the TWiT Brickhouse studio

Zen and the art of podcasting

I visited Podcast Mecca last week -- Leo Laporte's TWiT Brickhouse broadcast studio in Petaluma, California.

I got there just as Leo was starting Windows Weekly, Episode 373. There are several sets in the studio, and Windows Weekly is broadcast from one in Leo's office.

The start of the program

Here are some random impressions of my visit.

Seven of us were crammed into the office, facing Leo, as he did the show. There were two couples and three fan boys. (My wife was wandering around Petaluma -- not interested in coming in). The audience demographic surprised me -- several of us had gray beards. That was just the people in the room -- Leo's dog Ozzie was also a member of the office audience.

My first impression in seeing the small set/office was of clutter -- all sorts of geek brick-a-brack, old tech books, and tons of monitors, mobile devices, keyboards, cameras and lights. A box with a Harry's shaving kit was also on Leo's desk -- ready to be shown in a commercial.

Leo's cluttered office/set seen through the window

Leo is super friendly and informal -- "flirting" with the small audience in his office. One of the guys had a full beard, which his wife didn't like. Leo teased them and, after the show ended, he gave her the shaving kit. (I overheard one of the staff complaining that he had given away their only kit).

It seems like Leo is just shooting the breeze with his co-host (Paul Thurrott in this case), but he is watching monitors showing the co-host, chat room, on-the air stream, topic rundown, queued stills and videos, his large-screen Mac, etc. He juggles all this effortlessly with his right hand on the console shown below.

Leo controls the show using the console on the right.

Leo multi-tasks during the program. The console on his right has a button that toggles the studio on/off the air and he is constantly going off the air to do things like unpack a new phone that arrived during the show, fiddle with a tablet, order lunch, eat bites of lunch, yawn, drum his fingers on the desktop, etc.

At first, you wonder if he is bored or not paying attention while off the air, then he toggles on and offers an astute comment or asks a good question -- he is attentive to the on-air conversation at all times.

Leo fidgets a lot, but is not nervous -- he seems totally relaxed while he rolls around or bounces on the large rubber ball he sits on. That relaxation shows through in the show.

Leo is meticulous -- after unpacking his new phone or the Harry's shaving kit, he carefully repackaged them during off-air moments. He (and therefore TWiT) does things properly, without loose ends.

As soon as he finished Windows Weekly and posing for souvenir photos, Leo switched his attention to the upcoming episode of This Week in Google -- he had switched context as completely and quickly as when he went off-air for a bite of lunch. He seems laid back, but is focused and mindful.

The guy is a total broadcasting pro.

The TWiT studio is also highly professional. It is filled with workstations for monitoring and controlling broadcasts and editing video.

There are several sets and control stations in the studio.
There are other sets -- for groups of in-studio participants and other shows. A few minutes after the end of Windows Weekly, Leo had moved to another set where he was preparing do This Week in Google with Jeff Jarvis and Gina Trapani. As shown here, the audience sees Jeff and Gina in monitors behind Leo and he sees them on monitors behind the audience.

Leo on a different set, ready for This Week in Google

Leo's professionalism was underlined at the end of Windows Weekly. If you are a TWiT fan, you are used to the format in which programs begin with a brief summary of the upcoming episode, its title and a short promo for each of the sponsors. As soon as the show went off the air, Leo asked the chat room to suggest a show title -- and then extemporaneously recorded what would become the intro to the show when it was posted online. No effort, totally natural and done in a minute.

If you are interested in seeing a state of the art podcasting facility and having some fun, I heartily recommend a visit to the TWiT Brickhouse. The technology and buzz are reminiscent of the pre-slick, early days of live television, when you felt the sense of good humored, spontaneous experimentation and often saw the technology -- the cameras, cameramen, lights, etc. on screen.

It felt like the early days of live television.

Just in case you think I am making this up -- check out this picture with Leo after the show -- wearing the obligatory TWiT fezes.

After the broadcast

-----
Update 8/10/2014

I've noted Leo's ability to multitask and remain present in the on-air conversation. I just listened to TWiT 468, the episode recorded the week after my visit to the studio, and Leo confirmed my observation by discussing his attention deficit disorder (ADD). He told his on-air guests (who also claimed to have ADD) that when he is on air "I've got people in my ear, i've got things going on -- I just took a walk around the block while you were talking ..." (About 1 hour 10 minutes into the recording).

He and the guests seemed to agree that having ADD was helpful in their work in tech journalism, and Leo wondered about causality, asking
Are ADD people naturally attracted to tech or, and I think there might be some evidence for it, is all of this stimulus making us all a little bit ADD?
There is some evidence that the latter is true -- -- I know it is for me -- but I am not sure about the former.

This focus on ADD and multitasking reminded me of a biography I'd read of the writer D. H. Lawrence, who was said to be able to write and carry on conversations at the same time. (Conversing and drawing at the same time is pretty easy -- try it). Was Lawrence a super ADD multitasker? Is Leo? Is the Internet giving us all a bit of ADD?

NBC's Tour de France app -- three stars and five suggestions

NBC is learning how to present live sporting events on the Internet, but still has a way to go.

I've been commenting on the online coverage of the Tour de France and the Olympic Games for several years. The BBC and IT4 in England have done a better job than NBC, but NBC is improving their sporting event coverage and I enjoyed this year's Tour using their iPad app. (They also have Web and Android versions).

Let's look at the app. The user interface has five modes -- live video, standings, stages, riders and more:

Five viewer modes

You spend most of your time in the four-frame live video mode:

The four-frame live video user interface

Live video is shown in the upper left, and one can toggle the video to full screen. The text column on the right has frames showing the peloton and other rider groups and a curated, Twitter-like news feed. The graphic frame at the bottom has five optional modes, as shown here:

Options for the bottom window

The user can zoom or pan the bottom frame, as shown here:

Bottom window zooms and pans

The text windows on the right scroll and nearly every object on the screen is a hot link. For example, touching the word Peloton below popped up a scrollable list of the names of the riders in the peloton. Touching the rider's name, would bring up data about him.

Most objects are hot links.
I spend most of my time watching live video, but frequently switch to one of the other modes to check the standings or to see how a particular rider, team or nation is doing.

The stages mode is most interesting. It has facts about each stage and, more important, archives of the completed stages. Shortly after a stage is completed, you can go back and watch highlight clips or the video of the entire stage and review the standings and other statistics.

Finally, The biggest improvement over last year was not in the data presentation or user interface, but in NBC's offer -- I paid $14.99 and there were no commercials!

Suggestions for next year

The viewing experience was better than last year, but I'd still like to see several improvements.

1. As we saw above, the live presentation consists of a video stream and three data panes. The data panes and video are synchronized as long as you watch it in real time. If you pause the video for a short time, it "fast forwards" to the current live point, where it is in synch with the ancillary data. But, if you pause for a relatively long time -- maybe half an hour or an hour -- the video resumes where you left off, but the data stream reflects the current state of the race so they are out of synch.

Check the following screen shot. The riders in the video pane are climbing a steep mountain, but the course-progress pane at the bottom of the screen shows them on the subsequent descent (blue). The text on the right is synchronized with the course-progress map, so it is also out of synch with the video.

The video and ancillary (bottom and right hand) material are out of synch.
After pausing, you should have the option of picking up where you left off or jumping to the current point in the race. Either way, the video and ancillary material should remain in synch.

2. A complete archive copy of the video of a stage is posted shortly after it ends. That is good, but the ancillary material -- group positions and news posts -- is not available. Viewing the archive video is like watching a TV broadcast -- not an Internet performance. They should archive the synchronized data stream along with the video.

3. While watching the live stream or an archive stream, I'd like to have a single-touch, 15-second video rewind, as in the UK ITV4 viewer.

4. Similarly, I would like to be able to jump to the start of a video "chapter" with a single click or tap as you could with the BBC's player from the 2012 Olympic Games. A chapter might be something like the finals of the 100 meter dash in the Olympics or the sprint to the top of a mountain during the Tour de France. The person who is maintaining the ancillary news feed would create the chapter entry points as they posted the news updates.

5. The tablet interface is suitable for "leaning forward" -- switching modes and looking things up, but the small screen in your hands or lap is not so great for just "leaning back" and watching the race. I want to be able to mirror the video on my TV screen with a single touch.

I was watching on an iPad, so could have done that if my TV set were equipped with an Apple TV interface device. I don't have an Apple TV, but I do have a Google Chromecast, and Google just announced the ability to mirror the screen of selected Android phones and tablets on a Chromecast-equipped TV set. The updated Chromecast app is labeled "beta," and it took me two reboots to get it to work, but as you see here, I can now cast my phone video to my TV set:

Mirroring a phone on a Chromecast-enabled TV set
(This video is not from the NBC app because I have that installed on an iPad, not my phone).

The video quality is good, though not excellent. The imperfection is most noticeable on text which is part of the video stream -- it is a little blurry around the edges. Static text looks fine from across the room. Chromecast mirroring works if you have a compatible phone or tablet, but, hopefully by next year, NBC will Chromecast enable their app, allowing for switching between leaning forward to display data, post tweets, etc and leaning back to watch the race on a TV screen.

At first, new media mimic old media and NBC's earlier attempts at covering live sporting events online was shaped by their traditional TV coverage -- shoot video and insert commercials. This year, they have developed good ancillary data capability to go along with their video and dropped the commercials for a flat fee. Once they get the video and data synchronized and archived and I can lean back and watch the video or lean forward and play with the data, I'll give them five stars.

Kids are not waiting for schools to go online

My grandson Oscar will enter the 9th grade this fall and he and a friend are working their way through Algebra II at the Khan Academy this summer. No one told them to do it -- no one assigned it – they just decided to do it on their own.

It turns out that Oscar and his friend may not be all that unusual. UCLA conducts an annual survey of incoming first-time, full-time college freshman and they included two questions about student's experience with online classes in the 2013 survey:

  • Have you used an online instructional website (e.g.,Khan Academy, Coursera) as assigned for a class?
  • Have you used an online instructional website (e.g., Khan Academy, Coursera) to learn something on your own?
The following table shows the percents of students who answered frequently or occasionally:

Overall, more than 40 percent of the incoming freshmen were frequently or occasionally assigned to use an online instructional website during the past year and nearly 70 percent had used online sites on their own.

Digging a bit deeper, we see that students entering public schools were a little more likely to have online experience than those entering private schools. (Public colleges and universities also offer more online instruction). To me, the most interesting finding was that students entering historically black colleges and universities are much more likely to have online education experience -- on their own or assigned -- than the typical incoming freshman. I could speculate on the cause of this discrepancy, but it really requires further research.

College expectations correlate with high school experience -- students who are going to historically black and, to a lesser extent, public schools are more likely to expect to take online classes in college:

The survey also yields some insight into the importance of having used online classes. They correlate online participation with a multi-dimensional positive habits of mind index and conclude that
Students who chose to independently use online instructional websites are also more likely to exhibit behaviors and traits associated with academic success and lifelong learning.
My grandson Oscar and his friend may be ahead of the curve, having been assigned Khan Academy lessons while in junior high, but it looks like today's kids know the Web is good for school work as well as playing games, posting selfies and building Minecraft worlds.


1. Note that I have focused on the online instruction portion of the survey, but it covers many other characteristics of incoming freshmen.

2. Components of the habits of mind index:

Comcast executive apologizes for obnoxious phone call to a customer service rep -- ex customer rep says it was in line with company policy.

Last week this bizarre recording of a call to a Comcast phone representative requesting termination of service went viral. (You can listen to the first couple minutes then stop because it is repetive to say the least).

A senior vice president at Comcast publicly apologized for the call, stating:
We are very embarrassed by the way our employee spoke with Mr. Block and Ms. Belmont and are contacting them to personally apologize. The way in which our representative communicated with them is unacceptable and not consistent with how we train our customer service representatives. We are investigating this situation and will take quick action. While the overwhelming majority of our employees work very hard to do the right thing every day, we are using this very unfortunate experience to reinforce how important it is to always treat our customers with the utmost respect
Great -- except that Lauren Bruce, a former Comcast customer account executive says the customer service rep in the recording was not going rogue, but adhering to company policy. Bruce says the Comcast rep in the recording was trying to upsell the caller and also complete a mandatory questionnaire they had for each call. She says it was sometimes easier to make up answers than get them out of irate customers and that the customer rep in this call is being made a scapegoat.

This call recording with a Comcast rep makes my experience with Time-Warner Cable look good. It's no wonder the Internet Service Provision is the lowest rated industry in the United States according to the University of Michigan Customer Satisfaction Survey.

-----
Update 8/7/2014

Here is a copy of the Comcast retention representative handbook -- the call rating system encourages them to be persistent and -- "take control, ask targeted questions, make an offer", etc. I'd hate to have their job -- it's like working on an electronics assembly line.

NBC's Tour de France coverage -- four stars

NBC is learning how to present live sporting events on the Internet.

I've been commenting on the online coverage of the Tour de France and the Olympic Games for several years and the BBC and IT4 in England have done a better job than NBC ... until now. This year, I am watching The Tour using NBC's iPad app, and I like it a lot. (They also have Web and Android versions).

suggestions for next year

The viewing experience is good, but I'd still like to see some improvements. One would be adding a single-touch, 15-second video rewind, as in the UK ITV4 viewer. Another would be showing the text frames -- group positions and news posts -- along with the archived video of the completed stages. (Currently you can only replay the video stream). There's also some missing data -- the rider database includes a biography field, but it is not populated.

Finally, the tablet interface is terrific for "leaning forward" -- switching modes and looking things up, but the small screen in your hands or lap is not so great for just "leaning back" and watching the race. I want to be able to mirror the video on my TV screen with a single touch.

If I had an Apple TV, I could do that now with my iPad. My YATS Podcast buddies tell me that Google is updating their Chromecast app to enable mirroring the screens of selected Android phones and tablets on TV sets equipped with a Chromecast device. Better yet, how about NBC Chromecast-enabling their app?

As I said at the start, I like this experience a lot. Some part of that is attributable to NBC's app and some is due to the inherent nature of a tablet and touch interface. I also like NBC's offer -- I paid $14.99 and did not have to watch any commercials. By next year, I expect to have a five-star setup for watching The Tour -- while leaning forward and while leaning back.

-----
Update 7/17/2014

I said one missing feature was the ability to sit back and watch race video on a TV set. Yesterday, I received an update to the Chromecast app that enables mirroring of an Android screen on a Chromecast-equipped TV set. As you see here, I can now cast my phone video to my TV set.


(This video is not from the NBC app because I have that installed on an iPad, not my phone).

This new version of the Chromecast app is labeled "beta," and it is a bit glitchy. I had to reboot the Chromecast a couple of times to get it to work.

When it is working, the video is quite acceptable, though not perfectly sharp. The imperfection is most noticeable on text which is part of the video stream -- it is a little blurry around the edges. Static text looks fine from across the room.

This brings us a step closer to the complete leaning forward and back experience for watching live sporting events -- closer to a five-star review.

-----
Update 7/20/2014

NBC has populated the biography field in the rider database and it is now displayed. That was an easy suggestion to satisfy, but the others will require some re-architecting of the system to provide access to a buffered version of the video in real time.

Update 7/24/2014

I stated that my biggest criticism of NBC's iPad app was that archived replays of the video coverage of completed stages are not accompanied by the synchronized course map, news feed and dynamic standings of the live coverage -- if you miss a live stage, you cannot replay the full experience from the archive.

I've now discovered a similar synchronization problem during the live presentation. If you pause the live playback for a short time then restart it, the video fast-forwards to the current live point, synchronizing with the ancilarry material, but, if you pause for a long time, the video does not catch up with the ancillary material so they are out of synch.

Check the following screen shot. The riders in the video pane are climbing a steep mountain, but the course-progress pane at the bottom of the screen shows them on the subsequent descent (blue). The text on the right is synchronized with the course-progress map, so it is also out of synch with the video.


That will cost them a "star" in my rating -- let's cut it to three stars.

My next desktop will be a Chromebase -- a Chrome-based all-in-one -- will yours?

My next desktop will be an LG Chromebase or something similar -- how about you?

A while back, I reviewed an Acer Chromebook, comparing it to my Windows laptop and a tablet. While the laptop remains my main computer, the Chromebook easily beat the tablet for my application mix. (More worrisome for Apple, my 10-year old grandson agreed -- he liked the Chromebook better than his iPad). But, now we have a new entry, the LG Chromebase, an all-in-one desktop running the Chrome OS and browser. How does it stack up against my laptop, tablet and the Chromebook?

Where does the Chromebase fit in?

The bottom like is that my next desktop will be an LG Chromebase or something similar -- like a chromebox with a good keyboard and display. To understand why, check out the following picture of my current desktops -- two old tower PCs running Windows 7 and an iMac.

Kids installing crapware (and playing games)

The towers are used as kid arcade machines and the iMac is used for Web surfing, email, Skype calls, video Hangouts and kid games. That's it. No resource-intensive applications like video editing. (Time Warner's Internet connectivity can get in the way of those video Hangouts, but that is a different rant).

I've not used a Chromebase, but, based on my experience with the Chromebook, I am confident that a Chromebase with 4 Gbytes of memory could handle all of my desktop applications. It would run them as fast as the desktops, boot way faster, be more reliable, and, most important, be locked down. Look back at the picture of that room full of little kids playing games -- how frequently would you guess they click on some bogus link and download some cool-sounding program that turns out to be crapware or worse?

Of course, all this holds for my desktop applications, but it may not for yours. What if there were a good, Chrome-based version of Microsoft Office -- would that do it for you? Still not satisfied? How about the equivalent of an audio editor like Audacity and an image editor like Paint.net? That would not be enough to get me to give up my laptop, but it would be getting close.

Microsoft has released Office for the iPad (too little too late?) and will soon have an Android version. Is a browser-based version be far behind?

In December 2008 Bill Gates wrote a memo warning that "allowing Office documents to be rendered very well by other peoples browsers is one of the most destructive things we could do to the company." In January 2010 Steve Jobs predicted that "The world is moving to HTML5." In September, 2012, Mark Zuckerberg said "I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native ... because it just wasn't there." (Yet).

I think they were all right -- the trick is getting the timing right (like the Mac, not the Lisa) -- LG thinks the time is right about now.

The cover theme of The Economist this week is "creative destruction in education."

There are four articles on digital education in the June 28, 2014 issue:

  • Creative destruction: A cost crisis, changing labour markets and new technology will turn an old institution on its head.
  • The digital degree: The staid higher-education business is about to experience a welcome earthquake.
  • A winning recipe: Two big Brazilian education firms, now in the process of merging, show how universities can do both quantity and quality.
  • Wealth by degrees: The returns to investing in a university education vary enormously.
The articles survey trends and developments and speculate on the future of both elite and mass-eucation universities.

For example, at MIT over half the 4,500 students take a MOOC as part of their course and half of their edX (MOOC) students come from developing countries. Anant Agarwal, who runs edX, proposes an alternative to the standard American four-year degree course. Students could spend an introductory year learning via a MOOC, followed by two years attending university and a final year starting part-time work while finishing their studies online.

In Brazil, private universities, are enjoying success with innovative blends of online, televised and in-person classes at widespread locations. At first they had the same sorts of problems as US trade schools face today, but they are now succeeding at offering effective, low-cost education.



Change is inevitable.

MOOC students are international, with
varying levels of education.

Brazil has innovative mass-education.

Public support is falling and tuition rising.

The US educated a relatively high
percent of the population in the past,
but South Korea is the leader today.

Brain damaged UI

In an earlier post, I described the difficulty of discovering options in a touch interface and the silliness of porting that problem to non-touch devices like laptops – and I suggested a solution.

That was a big, general problem, but there are also many small, specific UI glitches. Here are two, one from Apple and one from Microsoft to keep things even. Let's start with Apple.

I just “upgraded" iTunes for Windows. Before the upgrade, I saw a simple Refresh All button in the lower right corner of the screen. About once a week, I would launch iTunes, click that button and it downloaded the new episodes of the podcasts I subscribe to.

After the “upgrade,” the refresh button was gone and I did not see anything like it. I went to an Apple help forum, where, someone had asked about the same problem and learned that the refresh capability was still there, but one had to select the List tab then click on the unlabeled circular arrow in the upper left corner. Well hidden Apple!

Here's a UI glitch from Microsoft -- I put my Windows laptop into Sleep mode several times a day. To do so, I click on the Start button then slide the cursor over to click on the small arrow to the right of the Shut Down button, slide the cursor to the right and click on Sleep. That usually works, but since I am doing all of this with a trackpad and the arrow is small, I screw up and accidentally click Shut Down about once a month – wasting time and perhaps losing data.


Do some minor UI problems bug you? Let me know what they are in a comment.

Could Google provide Internet access in Cuba?

(Cross posted on http://laredcubana.blogspot.com/)

The obstacles are political, not technical.

Eric Schmidt and other Google executives traveled to Cuba where they met with members of the Internet community and the government. Google is providing Internet access in a few US Cities and is considering others -- might they provide Internet access in Cuba?
Consider the following:

  • Cuba has very little domestic backbone infrastructure, but they could afford to extend Internet connectivity via satellite.

  • Google has a geosynchronous satellite project that could serve Cuba.
  • Of course, both governments would have to agree for Google or any other satellite ISP to connect Cubans. I believe that, if the Cuban government would agree, the US would as well.

    But, the Cuban government has feared the Internet since the time of their first IP connectivity in 1996. At that time, there was high level debate about the Internet. The hard liners, led by Raúl Castro, argued against the Internet while others argued for a "Chinese" approach of supporting Internet use while censoring content and surveilling users. (It seems Fidel Castro was ambivalent).

    The hard liners won in 1996, but what about today? Schmidt reports that a "number of the people" he spoke with said "the eventual model of Cuba would be more like China or Vietnam than of Venezuela or Mexico." If some of those were young government officials, there may be a glimmer of hope.

    Update, July 3, 2014

    It is noteworthy that Jared Cohen, Google's Director of Ideas, accompanied Schmidt on this trip -- before joining Google, he was a member of the Secretary of State's Policy Planning Staff and served as an advisor to Condoleezza Rice and later Hillary Clinton.

    Stockholm: 19 years of municipal broadband success

    The Stokab report should be required reading for all local government executives.

    Stockholm is one of the top Internet cities in the world -- how do they do it? Wholesale communication infrastructure in Stockholm is provided by AB Stokab, which is owned by the Stockholm City Council. Stokab leases dark fiber and space in nodes/hubs where customers can install communication equipment and interconnect networks since 1994. Stokab's goal has been to build a competition-neutral infrastructure capable of meeting future communication needs, spurring economic activity, insuring diversity and freedom of choice and minimizing disruption to the city’s streets.

    How has it worked out?

    Quite well, as you see in the following figure, taken from Stokab's report on the socio-economic cost and benefit of the project:

    Accumulated investments and socio-economic
    return in million Swedish Kronor.

    The returns shown here reflect increased property value, returns of the municipal housing companies (currently breakeven, due to large investments), value for tenants, increased employment, Stokab’s profit, saving for the municipality’s and county’s data and IT costs, and increased economic activity in the supplier industry. To drill down into the details, see the Stokab report summary or the full Stokab report.

    The Swedish Telecommunication regulator published a report calling for openness and competition at five Internet service infrastructure levels -- from physical access to land, ducts and spectrum through retail Internet service -- based on the Stockholm experience.


    A lesson for the US?

    The US needs infrastructure investment -- who will make it? The telephone and cable companies were given a chance, and they've dropped the ball. The Stockholm experience shows the role local government can play. National government's have also been important. The US Federal Government underwrote the research that gave us the Internet and governments like those of Singapore or China have worked as planners and venture capitalists. Home and building owners can also contribute to "last 100 yard" investment.

    Singapore's government acts as a planner and
    venture capitalist.

    Given the current US Congress, it is hard to imagine the Federal Government investing in Internet infrastructure, but FCC Chairman Tom Wheeler has praised municipal broadband efforts, wants to fight state laws prohibiting or restricting them and he is currently challenging Tennessee's anti-municipal net law.

    In spite of the fact that Wheeler came from the ISP industry, you have to like a guy who says:
    If the people, acting through their elected local governments, want to pursue competitive community broadband, they shouldn't be stopped by state laws promoted by cable and telephone companies that don't want that competition.
    The situation in the US will not change until the Internet becomes a political issue for the general public and that may be happening -- check out comedian John Oliver's piece on the Internet. Wheeler watched Oliver's piece and responded -- check that out too -- it's funny!

    ISP industry lobbyists claim that government involvement interferes with The Market, leading to waste and inefficiency, but in Stockholm, the municipal government has created a competitive market. This story is biased because we can't expect every local government to be as skillful as Stockholm's, but their example is worth considering.

    Supreme Court rules against Aereo -- but people want local TV online

    The Supreme Court says Aereo is distributing copyrighted material, but there is demand for their service.

    An Aereo antenna
    The Supreme Court has ruled against Aereo, a company that stores local, over-the-air TV broadcasts then streams then on the Internet. The Court ruled that Aereo was retransmitting copyrighted material without permission.

    Aereo deployed arrays of dime-sized antennae and claimed that they were merely leasing a speciic antenna to each customer and delivering content that was received by the customer's personal antenna.

    An array of tiny antennae

    The lower court case against Aereo challenged their technology claim -- questioning whether those dime-sized antennae were electronically independent. (If they were acting as a single, integrated antenna, Aereo would have been a clear copyright violator).

    Expert witnesses on the technology were divided during the first case -- Aereo's expert said the antennae were independent and the TV station's expert disagreed.

    The Supreme Court decision did not depend on a technology argument -- they held that Aereo was not in the antenna leasing business but were sellers of subscriptions to watch copyrighted television programs.

    I am a cord cutter and was cheering for Aereo, even though I questioned their technology claim and regarded their system as a kludge designed to get around copyright law.

    What about the future of local TV? If those tiny antennae really worked independently, Aereo could sell them to end-users and let them receive local broadcasts over the air, but I suspect they either do not work as claimed or only work if they are located very close to the transmitting antenna.

    Regardless, the current Aereo business model is toast, but they have shown that there is a market for local content delivered over the Internet. If customers are willing to pay for streaming of local content (including ads), why don't the copyright holders offer the service themselves or hire Aereo to do it for them?

    -----
    Update 7/1/2014

    I said that those dime-sized antennae seemed bogus to me -- that they could not truly be independent. Pete Putnam agrees and presents a detailed technical analysis supporting his conclusion that the antenna array would have to be within a couple hundred feet of the TV transmission tower for such small antennae to work independently.

    That is technical support for the broadcaster's assertion that Aereo was essentially doing the same thing as a cable company -- capturing and retransmitting copyrighted material -- but without paying the retransmission fees charged to cable companies.

    That raises the question -- how much are those retransmission fees? I went to the Dish Network Web site and found that "Local channels for non-qualifying packages are $6.00 per month." Dish evidently finds it profitable to pay the retransmission fees and charge customers $6 per month. They also offer "Superstaions" for $2 per month each.

    So, why doesn't Aereo or someone else go into the legal business of paying the retransmission fees, keeping track of the number of viewers for the sake of advertising sales, and offer local channels over the Internet? Aereo showed there was a market demand for such service.

    Update
    7/20/2014

    I've expressed doubt over the technical feasibility of Aereo's claim that they were renting independent TV antennas to their customers, but the Supreme Court ruled that even if that technology did work, Aereo was essentially acting as a cable company. I suggested that they had demonstrated a demand for local TV over the Internet and suggested that they pay the retransmission fees and become a "cable" company. But, the Copyright Office does not agree that they are a cable company, and, even if they are, the broadcasters might be able to force them to carry arbitrary bundles of channels like they do "real" cable companies. I am not a lawyer, but it seems Aereo is finished. There is demand for local TV streamed online -- will the broadcasters allow that to happen at any price?
