App challenge: what if you knew an earthquake will hit 5 seconds from now?


The biggest natural disaster threat to Californians comes from earthquakes, wild fires notwithstanding. One quake can take out more homes, businesses and infrastructure in a few seconds than all of this year’s fires combined. There’s no scientifically valid way of predicting earthquakes, so most people assume they strike without warning.

Not so. Earthquakes run for many seconds, even minutes. The first vibrations that ripple out are called P-waves, which seldom do damage but carry critical information about location and intensity several seconds ahead of the big shake. The U.S. Geological Survey and west coast research universities have a pilot program in place to monitor P-waves, and send out alerts. It’s in the early stages right now, and only a few agencies are connected. BART, for example, is using it to slow down trains before the main force of an earthquake hits.

The next step is to figure out how to push that information out to the public in time for it to be useful. The City of Los Angeles has a request for proposals out, looking for a developer who can develop a mobile app that’ll deliver meaningful and useful information to the public within ten seconds of the first alert from the USGS system. The first step will be to develop an app that can beta tested by city employees. It’s intended to be an open source project. The code has to be published on GitHub and published on an open source platform.

The technical work is the easy part. The harder question is, what will people do with the information? USGS says that “the warning time would range from a few seconds to a few tens of seconds”. If ten seconds or more are eaten up processing and delivering the alert, and a few more seconds are needed for people to pick up and read their phones, there’s not much time to react and take useful action. Solving that problem will be the truly difficult, and interesting, challenge.

Arizona innovates self driving cars while California pioneers regulation


California is on the receiving end of another slagging for its top heavy approach to regulating the development and deployment of self-driving cars. Ian Adams works for the R Street Institute, a Washington, D.C. consulting group – AKA think tank – that finds its home on the dark public policy corner where industry, academia and government intersect. Writing in The Hill, he points to the departure of the Waymo – formerly Google – autonomous vehicle venture for free range Arizona…

The reasoning behind Waymo’s deployment decision was simple: California opted for an overly prescriptive approach to regulating technological innovation. The state’s regulatory process simply too slow for it to capitalize on its seemingly insurmountable natural advantages…

Meanwhile, down in Arizona, Gov. Doug Ducey’s aggressively pro-growth administration issued an executive order to encourage self-driving vehicles, with only the barest necessary constraints on how they may be deployed. Since then, predictably, developers have flocked to the state.

He has a point. California took an early lead in opening the door to development of self-driving technology, but instead of offering a gateway to the open road, the door led to a bureaucratic maze. When the California department of motor vehicles slapped down Uber, the governor of Arizona scored quick and easy points by welcoming them, and any of the other 20 companies operating under the DMV’s supervision, to his state.

It worked.

The DMV’s response was to double down and publish new draft rules last month that close the loophole Uber thought it saw, generally tighten up language defining self-driving cars and adding new red tape to the testing process.

Autonomous vehicles are a step into the unknown for everyone, industry, consumers and government officials alike. The word for that is pioneering; a word we expect to find in the same sentence as California and high tech. But expectation is not entitlement. Unless the DMV rethinks its role, it’s a word we won’t be hearing as often.

Commercial drone experiments outsourced to cities, counties


Local governments have a chance to jump into the drone development business, by invitation from none other than the Trump administration. An order signed by president Trump gives the Federal Aviation Administration three months to create a program that will allow local, state and tribal governments to propose unmanned aircraft system (UAS) pilot projects, in partnership with private companies, to see what might and might not be feasible to write into FAA regulations in the future.

The “presidential memorandum to the secretary of transportation” directs the department – and the FAA in particular – to…

Solicit proposals from State, local, and tribal governments to test within their jurisdictions the integration of civil and public UAS operations into the [national air space] below 200 feet above ground level, or up to 400 feet above ground level if the Secretary determines that such an adjustment would be appropriate…

[And] enter into agreements with the selected governments to establish the terms of their involvement in UAS operations within their jurisdictions, including their support for Federal enforcement responsibilities; describe the proposed UAS operations to be conducted; and identify the entities that will conduct such operations, including, if applicable, the governments themselves.

Proposals will be screened with the goal of authorising programs in a wide variety of geographic, economic and technological circumstances, and using a diverse range of public-private partnership models. The memo calls out five policy objectives:

  1. Promoting innovation and economic development.
  2. Enhancing transportation safety.
  3. Enhancing workplace safety.
  4. Improving emergency response and search and rescue functions.
  5. Using radio spectrum efficiently and competitively.

The marquee application is package delivery – Amazon and Google are getting a lot of buzz around that – but real world proposals are likely to be more, um, down to Earth. Agricultural technology applications for drones are rapidly growing, and rural communities interested in pursuing projects would have a couple of advantages: they usually can respond to opportunities faster than urban cities, and lower population density simplifies the technical and regulatory challenges.

Peru flooding kicks Project Loon into the real world


Project Loon demonstrated a real-world usage case earlier this year, when the worst flooding in decades hit Peru. The stratospheric balloon-based broadband system under development by Alphabet, Inc. – Google’s parent company – was deployed to backfill mobile networks that were damaged or overwhelmed by the disaster.

That’s according to Anne Bray, Project Loon’s business development director. She was speaking at the inaugural Mobile World Congress Americas trade show in San Francisco last week.

She said that Project Loon began working with Telefonica in Peru a year ago. It was a testing ground for, among other things, balloon flight operations, including a long duration flight that began at a base in Puerto Rico and then remained on station over Peru for 14 weeks. When the floods hit, the program accelerated, launching balloons and scaling up to reach tens of thousands of people in a short amount of time. It was a new experience. Up until then, Project Loon’s deployments were still largely research projects; all of a sudden it was an emergency responder.

Project Loon is a wholesale play. It partners with terrestrial mobile companies in rural areas, and provides bandwidth to areas that they can’t reach, or where existing infrastructure can’t handle the load.

Using a solar-powered transciever – basically, a small cell site – attached to a balloon that floats at an altitude of about 20 kilometers, one Loon access point can cover about 5,000 square kilometers. Bray said they’re aiming for gigabit-class throughput on each balloon. Project Loon’s website specs the service as delivered to a user on the ground at 10 Mbps.

Early tests were with Vodaphone in New Zealand, but those were tests. Although commercial deployments were promised to follow quickly, it’s been slow to roll out. The flooding in Peru appears to be the catalyst that kicked Project Loon into something like a real world operational mode.

Feds ready to tell California DMV to drop self-driving car rules


The U.S. congress isn’t completely gridlocked, at least not where self-driving cars are concerned. This week, the U.S. house of representatives passed a bill – with a whopping bipartisan majority – that would put the federal transportation department in charge of setting standards for autonomous vehicles, and determining whether or not any particular design is safe to operate on open roads, anywhere in the country. If it makes it into law – it still has to be approved by the U.S. senate and signed by the president – California won’t be able to set its own rules for autonomous vehicle operation…

No State or political subdivision of a State may maintain, enforce, prescribe, or continue in effect any law or regulation regarding the design, construction, or performance of highly automated vehicles, automated driving systems, or components of automated driving systems unless such law or regulation is identical to a standard prescribed under this chapter.

States would still be responsible for regulating “registration, licensing, driving education and training, insurance, law enforcement, crash investigations, safety and emissions inspections, congestion management [and] traffic”, but only if those laws are not “an unreasonable restriction on the design, construction, or performance of highly automated vehicles, automated driving systems, or components of automated driving systems”.

Next week, the Trump administration is expected to announce a parallel effort to federalise self-driving car oversight, and early leaks of its plans seem to track with both the house bill and a regulatory system outlined last year, by the Obama administration. There’s also a bill pending in the U.S. senate that takes a similar, but not identical, approach.

Assuming this Beltway love affair with autonomous vehicles doesn’t run out of gas, Californian regulators will have to scrap its current rules and pull back on plans to expand them. That’s likely to have a positive impact on self-driving car development here, since it’ll remove most of the regulatory incentives to head to Nevada or Arizona, as Uber did last year when it butted heads with the California department of motor vehicles.

FINsix Dart universal power adaptor works great, when it works


From pitch to product, with some bumps in the road.

It’s not often I have the pleasure of actually using a product that’s made it from the fundraising stage all the way to the open market. One of the top finishers at the 2014 Showstoppers LaunchIt beauty pageant, held during the Consumer Electronics Show, was FINsix, which was pitching a small, universal power supply for laptops and phones. It took second place, largely, it seemed, on its personal appeal to the judges who, as I noted at the time, had a “gleam in their eyes as they thought about trading two power bricks for one that’s barely bigger than a plug alone”.

It attracted me too, but remained off limits because my main laptop is a Mac and FINsix doesn’t offer the necessary MagSafe 2 adaptor tip. The key word is offer – as I later discovered, it’s available. Sorta.

While getting ready for a bicycle tour, I slimmed down my electronics load and opted to bring a Lenovo N22 Chromebook instead of the Mac. It’s a light and very rugged device that’s designed to be tossed around by elementary school kids. It comes with a power supply that was bigger than I wanted to carry, so I bought a Dart, which is the FINsix product’s trade name now.

The first one that arrived didn’t have an adaptor tip that fit the N22. I emailed customer service, and they quickly sent me one – it’s not included in the standard kit. That’s when I discovered that my Dart didn’t work at all. It wouldn’t charge anything, and the indicator light on the cord didn’t come on. It was dead and then customer service slowed down. It took a couple of days to get a response, and then a couple of weeks to get a replacement unit – I left on my month long bike tour before it arrived.

When I returned, the unit was waiting for me. It seemed to work – the light came on and it charged my phone. But not the N22.

At that point, customer service sped up again, and a couple of rounds of troubleshooting resulted in the discovery that the tip actually doesn’t work on an N22. At that point, they sent me a MagSafe 2 tip. It’s not a regular product, but it can be kluged together with a “snip tip”, which is a adaptor that can be soldered onto unsupported plugs. That worked perfectly, and now my briefcase is lighter and less cluttered – exactly what was promised three years ago.

My conclusion is that the Dart is a great product concept, but FINsix is having some trouble implementing it. That’s based on a very small sample, though. I might just have been that one unlucky guy. And FINsix did give me a solution that’s better than my original plan, so kudos to them.

Bitcoin’s disruption is the healthy and rewarding result of a free market


Cryptocurrencies like Bitcoin are different from other software and standards-based platforms. There are no governing authorities or dominant players or established industry groups. That’s deliberate. The whole point is to create a way of exchanging value that’s not centrally regulated by governments or private organisations. But that means a super-majority of the millions of individual users have to accept and adopt software updates, or else there’s the risk that Bitcoin will splinter into different versions with different values.

That’s what happened last week. The debate within the Bitcoin community over the best way to increase the capacity and speed of the underlying software resulted in a tenuous compromise earlier this year between many users with different interests. But not all of them. So on Tuesday, another big group agreed on a different method of updating the software and began running it their own way, in the process creating a new version called Bitcoin Cash.

Anyone who had one Bitcoin on Monday now has one unit of Bitcoin and one unit of Bitcoin Cash. The splinter group is big enough that the new unit of Bitcoin Cash actually has some value. It’s fluctuated wildly, but might – might – be stabilising in the $200 to $300 range. On the other hand, it’s not big enough (yet) to have hurt the value of the original Bitcoin, which topped $3,000 for the first time yesterday.

The drama isn’t over. A cryptocurrency’s value is, from the beginning, the cumulative result of millions of freely made, individual decisions, rather than a declaration made by a central authority that’s then moderated by whatever market forces are allowed. The compromise within the original Bitcoin community hasn’t been implemented yet and could fall apart, producing even more versions of the currency. That’s the inevitable – purposeful – risk of an unregulated medium of exchange. So far, as Bitcoin holders learned today, that risk is overwhelmingly outweighed by the reward.

Cryptocurrencies’ crowd source incentives prevent collapse into one crowd


The disruption in cryptocurrency markets this week, when Bitcoin sorta split into two, was the result of disagreements between different interests about the technology and crowd-sourced methods used to run it. It was also inevitable and purposeful – cryptocurrencies are intended to rise and fall according to the cumulative decisions of millions – eventually, billions – of sovereign, individual users, who won’t always agree with each other.

Bitcoin’s underlying software can’t keep up with the growing number and speed of transactions between its users. The limits of the software has been a known problem for years, but the urgency of solving it has increased in the past few months as the strain on the system began to slow down transactions.

The solution is simple: upgrade the software. But sometimes simple things are supremely difficult, and so it is with Bitcoin.

It’s nothing like updating a commercial application like Excel or iTunes that’s owned by a single company – Microsoft or Apple just do it. It’s not even much like Linux or other widely used open source software that can comfortably exist with many different versions – distros – floating around. Linux might be open source, but any given installation is a closed system – so long as you’re satisfied with the way your preferred version runs on your hardware, all is well. Operationally, it doesn’t matter if the person sitting next to you uses a different distro.

But if you’re exchanging information with other people – which is what Bitcoin is all about – then everyone has to format and process the data in the same way. Email works because everyone has more or less settled on a set of open standards that are periodically updated by industry groups that include big companies, like Google and Microsoft. If enough of the major players agree then pretty much everyone else has to follow along, or risk being shut out.

The same principle applies to cryptocurrencies like Bitcoin, but because schisms like we saw this week produce competing versions that, so far, have added value to the overall market and can be freely exchanged within their respective universes, there’s also an incentive to not standardise. By preventing consolidation into a single, monopoly platform, that balance has kept an ecosystem of independent cryptocurrencies alive.

Microsoft discovers Google’s business model in spectral gaps


Me too.

Microsoft’s TV white space broadband initiative is many things – a worthy effort to expand Internet access, a way of squeezing more useable bandwidth out of finite radio spectrum, a call to action for rural economic development and, as willingly acknowledged, a business opportunity.

It is also a foray into the market economics of free software. White space is the gaps between active television channels, which vary according to where you are in relation to whatever TV stations might be around. The proposed solution to this spectrum management problem is active management via databases run by private companies. Like Microsoft.

Or like Google. Which opened up its database to all comers four years ago. Microsoft’s answer, which is wrapped in a well articulated but completely ordinary white paper about rural broadband access, is to offer up its intellectual property in a similar manner…

Our Rural Airband Technology Program will make our U.S. patents available under a royalty-free license to all comers, including to our competitors, for any work they undertake to stimulate broadband access through TV white spaces. These patents help tackle common problems associated with TV white spaces in a variety of ways…

Microsoft’s database-driven TV white spaces technology has continuously been improved through the use of machine learning that populates, maintains, and improves the content of the database, and cloud-based analytics to respond to database queries that, for example, leverages prior spectrum assignments for particular devices.

Google went from a Silicon Valley garage start up to being (at times) the world’s most valuable company by amassing vast quantities of data, giving away software that can make efficient use of it and then making gigabucks as the resulting traffic passed through – and made detours into – its servers.

In that context, its open access white space venture was nothing remarkable. And from that perspective, neither is Microsoft’s. Except that, well, it’s Microsoft. Welcome to club.

Texan judges and juries can’t hold high tech hostage any more


Goodbye to all that.

A particularly pathological cottage industry in east Texas is coming to an end, much to the delight of high tech entrepreneurs, and they have a low tech court case to thank for it. The federal supreme court ruled that patent trolls can’t go shopping for the most easily bamboozled judges and juries, but instead have to file law suits in the home state of the companies they’re trying to shake down.

According to a story in the Hill, the decision came in a case where Kraft – decidedly not a troll – tried to sue an Indiana-based company, TC Heartland, over water flavoring technology in a Delaware-based court…

The ruling will have broad implications for patent lawsuits, which are frequently moved to certain districts that have a track record of being favorable to patent infringement claims.

In delivering the court’s opinion, Justice Clarence Thomas wrote that much of the decision hinged on the word “resides,” which the court found to mean state of incorporation. Thomas wrote that because of this interpretation, updates to the rules by Congress did not change a 1957 Supreme Court decision that had previously found that patent suits must take place in the targeted company’s home state.

Though the TC Heartland and Kraft case focused on a disagreement between whether the case should take place in Indiana or Delaware, 40 percent of all patent suits are filed in east Texas. Ninety percent are brought in by “patent trolls,” or companies that hold patents but do not manufacture or produce anything, according to the Stanford Law Journal.

The decision hits trolls and the east Texas predatory bar that serves them, but it will also impact communities there. Big corporations, such as Samsung, have focused community relations dollars on east Texas, in the hope of building friendly relations with potential future jurors. Samsung might be able to afford to waste money on such endeavors, but few others can. The court’s ruling isn’t the end of the war against patent trolls, but it is a decisive battle.
