O2 4G data network restored after day-long outage - BBC News, Dec 2018
“Ericsson UK boss Marielle Lindgren said the "faulty software" that had caused the issues was being decommissioned. … Ericsson said there had been network disruption for customers in multiple countries. Ericsson president Börje Ekholm … said "an initial root cause analysis" had indicated that the "main issue was an expired certificate in the software versions installed with these customers".”

Outages show the need to think clearly about national security | PolicyTracker: Dec 2018
"On Thursday, millions of smartphone users in the UK lost their data services after the O2 network suffered technical problems. While the problem only lasted a day, it was one of the biggest mobile network outages because it hit the many external services that rely on the operator’s data network."

"The blackout raises questions over the future of mission-critical applications. What will happen when 5G networks underpin a country’s water supply, electricity grid, emergency services and even self-driving cars?"

"Isn’t it time for an evidence-based approach to the security of networks, based on independent testing of equipment from companies which are prepared to cooperate? Anything else looks suspiciously like a backdoor way of damaging potential competitors."

In Way Too Little We Trust - Adam Garfinkle, The American Interest, Dec 2017
Via Pierre-Yves Saintoyant

"The essence of all this is that people who share common mazeways from having lived together and been socialized generation to generation can anticipate what others are up to, and the result is a network or web of reciprocal shared expectations."

"The ballast provided by social trust enables a relatively light-handed government to do for a collection of communities in a larger country only what they cannot readily do for themselves."

"... seven factors [my numbering]— [1] immigration-driven heterogeneity, [2] the decline of traditional religious mores and related informal norms, [3] technology-driven isolation, [4] the backwash of institutional dysfunction and elite dethronement, [5] the media-driven “mean world syndrome,” [6] family instability and breakdown, and [7] the excessive intrusiveness of the state"

"This suggests that, however the problem arose, the decline of social trust has taken on a downward-spiraling life of its own, generating not only a compounding lack of trust but also an ambient pessimism about the future. So we have not just a problem, but a problem set defined by these seven causal elements."

"If we are driven nearly berserk politically by current levels of labor displacement—and we are—we will clearly enter the domain of full-frontal social unsustainability if the challenge more than quadruples in a single generation. And yet at present there is absolutely zero prospect that the American political class will do anything about this. Some people are terrified about what a rising deficit could mean, but compared to the existential threat to social order posed by an automation-driven political economy derangement of this magnitude, the deficit problem, serious as it is, seems like no more than a bad hangnail."

Costs and consequences of wind turbine wake effects arising from uncoordinated wind energy development | Nature Energy, Nov 2018
Via Nature podcast
"Optimal wind farm locations require a strong and reliable wind resource and access to transmission lines. As onshore and offshore wind energy grows, preferred locations become saturated with numerous wind farms. An upwind wind farm generates ‘wake effects’ (decreases in downwind wind speeds) that undermine a downwind wind farm’s power generation and revenues. Here we use a diverse set of analysis tools from the atmospheric science, economic and legal communities to assess costs and consequences of these wake effects, focusing on a West Texas case study. We show that although wake effects vary with atmospheric conditions, they are discernible in monthly power production. In stably stratified atmospheric conditions, wakes can extend 50+ km downwind, resulting in economic losses of several million dollars over six years for our case study. However, our investigation of the legal literature shows no legal guidance for protecting existing wind farms from such significant impacts."

Is the FDA Too Conservative or Too Aggressive?: A Bayesian Decision Analysis of Clinical Trial Design, Aug 2015, Vahid Montazerhodjat & Andrew W. Lo
Via Tom Hazlett, Nov 2017

NBER Working Paper No. 21499
Issued in August 2015
NBER Program(s):Health Care, Health Economics

Implicit in the drug-approval process is a trade-off between Type I and Type II error. We explore the application of Bayesian decision analysis (BDA) to minimize the expected cost of drug approval, where relative costs are calibrated using U.S. Burden of Disease Study 2010 data. The results for conventional fixed-sample randomized clinical-trial designs suggest that for terminal illnesses with no existing therapies such as pancreatic cancer, the standard threshold of 2.5% is substantially more conservative than the BDA-optimal threshold of 27.9%. However, for relatively less deadly conditions such as prostate cancer, 2.5% is more risk-tolerant or aggressive than the BDA-optimal threshold of 1.2%. We compute BDA-optimal sizes for 25 of the most lethal diseases and show how a BDA-informed approval process can incorporate all stakeholders’ views in a systematic, transparent, internally consistent, and repeatable manner.

Sorry LEOs, but FPAs Have No Incentive to Go Low-Cost - NSR Dec 2018
"According to NSR’s Commercial Satellite Ground Segment, 3rd Edition report, antennas will generate $44.9 billion cumulative revenues in the next 10 years. Requirements are wide and varied, from low-cost, fixed parabolic dishes for DTH (can be as cheap as $10 USD), to highly sophisticated antennas for mobility or Earth Stations that can cost several $100k USD. Consequently, antenna vendors adapt their products to the most lucrative markets. LEO constellations have a particular set of requirements that favor FPAs, especially in the low-end markets, but are FPA incentives aligned with LEO Constellations?"

"Today, SAC in Consumer Broadband is around $700-1,000 USD where the modem might be in the $300 range, antenna itself around $50, installation contributing $100 and the rest being marketing, credit validation and others. Consequently, an FPA priced in the $200-300 range could compete with traditional parabolics considering lower installation and marketing costs (product placement). Even considering these factors, prices for FPAs are still far from this benchmark, and only the architectures that have no other option (LEOs, Aero) will choose FPAs in the short to medium term."

"It will be impossible to see FPAs beating low-end parabolics in a direct cost comparison but, when including other elements of SAC, the equation is not so unfavorable. With continuous technology development, greater traction from LEOs and stagnation in verticals like Aero, we could see consumer-grade FPAs by the mid-2020s, at the earliest."

NSR’s Satcom Financial Index 2018- Dissecting the Trends - NSR Dec 2018
"Recent (Q2 or Q3) financial results have been a mixed bag for the industry. Video revenues have consistently declined on a YoY basis for most operators including Intelsat, Eutelsat, SES and EchoStar Satellite Services, while most operators have posted gains in network connectivity – most prominently in Government and mobile connectivity verticals, including ViaSat. To say that the latter two verticals remain the growth story in the near term is a massive understatement – while one must also take into consideration significant progress in consumer broadband by Hughes and in mobile backhaul by SES (MEO)."

"Though, barring equipment sales by the top two integrated operators, overall growth looks to be lagging in 2018. Many satcom operators seem to be missing targets, especially on video, with capacity prices continuously falling even in developed markets of the world. There is likewise high regional competition, as well as the terrestrial pressure, and given that video still forms the bulk of the GEO industry revenues today, overall growth is stagnating in the near term."

SpaceX launch will rocket 71 satellites into space, help hunt pirates - Business Insider
"The trio of spacecraft belong to a startup called HawkEye 360, and they're designed to "see" radio signals from space. The company's software will take unique radio signals coming from ships to "fingerprint" vessels, track them over time, and even forecast future movements."

"A HawkEye 360 data visualization that shows every instance over a month in which a boat turned off its automatic identification system (AIS) for more than 8 hours."

"Pathfinder, like the other satellites SpaceX is launching, will sweep around Earth from pole-to-pole in what's called a sun-synchronous orbit — hence the "SSO" in the mission's name."

"The Pathfinder system relies on the fact that so many brands and models of radio transponders are used by ships. Minor variations in those devices , and the frequencies they use, lead to subtle differences in radio emissions that HawkEye 360 says it can detect and exploit. "

"The company expects the US military to be increasingly interested in the technology, especially considering that HawkEye 360 can deploy its sensors on airplanes and high-altitude balloons (in addition to satellites)."

Hume on Is and Ought | Issue 83 | Philosophy Now
"Hume’s idea seems to be that you cannot deduce moral conclusions, featuring moral words such as ‘ought’, from non-moral premises, that is premises from which the moral words are absent. The passage is summed up in the slogan ‘No-Ought-From-Is’ (or NOFI for short) and for many people it represents the take-home message of Hume’s moral philosophy. It is sometimes rather grandly referred to as Hume’s Law. But what exactly did he mean by it? Why did he think that his observation would ‘subvert all the vulgar systems of morality’? Is NOFI (or something like it) true? And what are the philosophical consequences?"

Sector-specific machine learning applications for improving business performance (including Retail, Agriculture, Transportation)

Weather forecasting is a strong fit for machine learning. The incredible volume of relevant information — historical data and real-time data — that can be analyzed is simply too great for any group of unaided humans to even begin to process on their own. "

"GE Current has installed smart street lights in several cities that can monitor things like light, humidity, and air quality."

"Panasonic has been working on its own weather forecasting model for years, and it stepped up its effort with the purchase of AirDat in 2013. The company makes TAMDAR, a speciality weather sensor installed on commercial airplanes. "

"According to IBM, 90 percent of crop losses are due to weather events and 25 percent of weather-related crop losses could be prevented by using predictive weather modeling."

A Price War Coming for Satcom IoT? - NSR Nov 2018
"on the horizon are many competing IoT network deployments that promise to significantly lower the cost of hardware and airtime costs associated with IoT and to open new markets. Given these new cut-price alternatives, where does that leave existing M2M operators, which have a higher cost base and higher service price?"

"New competition in this space includes the rise of small satellite constellations for IoT (despite some questionable business cases), Low Power Wide Area (LPWA) networks, and 5G connectivity, which is just around the corner. These new smallsat operators and LPWA networks intend to offer ARPUs of $1 per month, or even just a few euros per year. Low prices are also available on the terrestrial side, with Unabiz also announcing offerings as low as $1 per year. Sigfox even demonstrated a 20 cent terminal, which could bring in a new large market of disposable devices and tracking packages."

"By comparison, Iridium’s commercial IoT service ARPU was an order of magnitude higher at $13 per month in 2017, compared to $18 in 2012, indicating a decline in ARPU. "

"Will mass price cuts be unveiled once smallsat IoT constellations and LPWA networks are fully rolled out? The short answer: No"

"Like-for-like ARPUs will remain significantly higher than smallsats and terrestrial competitors, but taking into account MoUs and dual mode connectivity, overall satcom ARPUs will be lower."

EO Smallsat Market: Where to Go from Here? - NSR Nov 2018
"Smallsat operators, now more than 40, all expect to capture a sizeable piece of the EO downstream market. The questions are: How big is this pie and who is it for?"

"NSR’s Satellite-Based Earth Observation, 10th Edition report forecasts the EO smallsat downstream market will experience double-digit CAGRs, and cumulatively account for $9.7B in revenue over the next decade. Growth will come from all verticals, but a large segment of this growth is to arrive in the form of Big Data analytics for Defense & Intelligence and Managed Living Resources (Agriculture, Forestry, etc.)."

"Another factor driving change and growth in the industry is the devaluation of imagery and the growing focus on Big Data analytics. Currently, Big Data analytics players favor MR imagery due to its easier access and lower costs. However, upcoming supply and growing archives are serving to depreciate the cost of imagery, lowering the barrier to entry for utilization of HR imagery."

Will Software-Defined Satellites Take Off? - NSR Nov 2018
"... new architectures, multiple forms of heightened risk taking, and adoption of low or no heritage technologies. SES is pushing this process even further with proposals for a standard-build, software-defined satellite that could be purchased off the shelf for use in any orbital slot by any operator. Yet, with buy-in needed from both manufacturers and competing operators, will the idea take off?"

"The ability to change frequency bands, coverage areas, power allocation, and architecture (widebeam vs HTS, for example) on-demand, at any point in satellite lifetime, enables an operator to capture diverse markets. It can address new applications as they emerge, compensating if the initial target market falters, or more simply respond to a rebalancing of demand. Standard-build satellites also add flexibility to an operator’s fleet, making satellites interchangeable in the case of anomaly or shifting priorities."

"as is the case with any generalist/specialist tradeoff, a standard-build satellite will be able to address a broader overall array of demand but might not address individual markets as competitively as a tailored satellite."

"not only are standard-build/software-defined satellites on the table, but very high throughput satellites (e.g. ViaSat-3), smallsats in GEO (e.g. Astranis), condosats (e.g. GeoShare), blended GEO/MEO/LEO constellations, and in-orbit servicing and assembly, amid other budding ideas, are feasible pathways as well"

"While this cost and risk must be resolved, in principal standard-build satellites dovetail with what manufacturers have been considering for years: standardization as a way to cut costs and reduce production timelines."
