Broadband in the West Central Region of MN
Broadband access in the West Central Minnesota region varies greatly, with some areas well-served while others remain unserved or underserved. Federal subsidies to larger carriers like CenturyLink and Frontier have helped expand broadband to areas within 3,000 feet of existing infrastructure, but speeds drop off significantly beyond that and many areas still lack access. While technologies like satellite and fixed wireless have improved, limitations remain like latency, line of sight needs, and data caps. Upgrading networks to fiber would provide the best future-proof broadband but costs around $10,000 per home to install. The region needs improved broadband access to compete for residents and businesses, but subsidies are required to incentivize private investment in rural areas. Local leadership must

Wind energy
Wind energy is a clean and renewable source of energy without carbon emissions. It has advantages such as being sustainable and accessible to individuals, but also has disadvantages such as being an inconsistent source of energy that depends on wind patterns and takes up more space than fossil fuels. While wind energy is suitable for small towns, it does not produce enough power for large cities and has limitations based on location. Overall, more research is still needed to improve wind turbines' ability to generate energy on a larger scale.
Rebecca Ford “Prosumer Energy Culture and a Fractal Like Grid.”
This document discusses the concept of a "prosumer energy culture" and a fractal-like grid. It notes that households are increasingly producing their own energy through technologies like solar panels. This is shifting energy profiles and creating constraints on the traditional grid. A fractal grid that recognizes consumer values like independence, control and sustainability could help alleviate these issues through approaches like localized peer-to-peer energy sharing and collective prosumerism. It would incentivize distributed energy investment, increase resilience and allow greater utilization of renewable resources.
Green Neighborhood Challenge/Wind Power
The document promotes switching to wind power in Washington D.C. through the Green Neighborhood Challenge. It notes that D.C. is highly ranked for green energy use and individuals have freedom to choose their energy supplier. Signing up for wind power through Clean Currents makes it easy to support wind energy and donations will go to a local conservation organization. The Challenge runs until Earth Day and individuals are encouraged to participate to help their community become greener.
Does Your Neighbor Know that Energy Efficiency & Renewable Energy are Really ...
The reality is that, in communities like Pueblo, Colorado, energy efficiency and renewable energy offer enormous economic opportunity--to the municipality, to local businesses and national businesses with a local presence, to K-12 schools and to institutions of higher education, and to the members of the community themselves. The challenge is that, to most of mainstream America, these industries and their technologies remain largely opaque. From what the technologies are and how they can benefit, to how to finance them and measure their performance, EE and RE remain largely a mystery. How industry groups, business and--especially--public officials educate their stakeholders and constituents about the opportunity that lies within the EE and RE industries will determine the extent to which mainstream America can truly benefit from them and leverage their value.
Dominion:Coal to Clean Energy Presentation
The document outlines a campaign by the Virginia Chapter of the Sierra Club called "Dominion: Coal to Clean Energy" which aims to transition Dominion, Virginia's largest utility, away from its reliance on fossil fuels like coal towards cleaner energy sources. It discusses how Dominion is heavily invested in coal and is an obstacle to developing wind and solar in the state. The campaign's plan is to get Dominion to create 3,000 megawatts of new wind and solar in Virginia by 2020 in order to power 700,000 homes and move the state beyond its dependence on coal. The document calls on readers to get involved by signing a petition and joining the volunteer team working to promote clean energy in Virginia.
Energy sustainability
The document discusses sustainable energy options for Gotham City. It outlines the debate around the Indian Point nuclear power plant, which supplies 25% of the city's energy but faces environmental and safety concerns. The document also discusses New York Governor Cuomo's initiative to increase energy efficiency in state buildings by retrofitting inefficient structures and benchmarking energy usage. Finally, it presents ways for citizens to lower their energy consumption, such as using compact fluorescent light bulbs and investing in solar and wind power.
Amazed presentation
This document provides an overview of a Zero Energy District (ZED) initiative in Asheville, North Carolina called AMAZED. A ZED aims for residents and businesses to produce as much energy as they consume. The goals of AMAZED are to make Asheville energy independent and keep money in the local economy. Currently, Asheville gets most of its electricity from a coal plant, but progress has been made in reducing city and resident energy use. The document outlines potential strategies for AMAZED, such as education and competitions, and highlights examples of success in other communities like Fort Collins, Colorado. Preliminary participating organizations are listed and three simple energy saving tips are provided.

Digital Terrestrial TV to drive solar power uptake in Africa.
The imminent arrival of Digital Terrestrial TV (DTT) in Africa will have a significant impact on the drive for greater electrification in rural areas.
The migration from analogue to 2nd generation of digital television broadcasting DVB-T2 is about to take place across the continent of Africa.
There is a groundswell of interest in DTT as it will offer viewers substantially more terrestrial television channels than are currently available. The technology will help improve the picture and sound quality of broadcast programmes and also give viewers access to radio and a host of other value-add services.
However, the major problem facing countries throughout Africa is the limited availability of electricity in remote settlements.
The only viable option for rural households is renewable energy with new-generation, low-cost hybrid solar photovoltaic (PV) solutions being the preferred choice.
After adopting solar systems there is a dramatic change in customer behaviour and expectations. African want more than just lights.

Eddie A. Borejon Benefits of Solar
This document discusses the benefits of solar energy in three key areas: 1) It reduces air pollution and offsets greenhouse gases by providing electricity without emissions; 2) It conserves energy by powering rural areas and reducing the need for diesel generators; 3) It reduces the need for dry cell battery disposal which prevents environmental contamination.
Power to the powerless
1. Around 1.1 billion people globally lack access to electricity, most living in rural areas of South Asia and sub-Saharan Africa. Some entrepreneurs are developing off-grid solar energy systems to provide power, with payments made via mobile phones in small, affordable installments.
2. Governments and utilities often cannot afford to expand power grids to rural areas. People are also reluctant to pay for electricity as a public good. New payment technologies and social programs aim to change attitudes and encourage payment.
3. Companies providing solar home systems on payment plans that are paid off over time are having success getting initially unwilling customers to pay for small amounts of renewable power. Their lessons could help make grid electricity more accessible and

Four Ways that Start Ups Innovate
The document discusses four types of innovation that startups embrace: unintended innovation that occurs by accident, desperation innovation that emerges when there are no other options, collaboration innovation through diverse brainstorming, and perspiration innovation through hard work. It then describes four approaches startups use to innovate: not knowing any better due to inexperience, allowing an autocratic genius innovator as CEO, failing more cheaply as startups, and having huge motivation to innovate or die.
LAUNCH scale - Avoiding a Culture Implosion As You Scale Your Startup
Earlier this week, I had a chance to speak at one of Silicon Valley’s larger Startup Events, LAUNCH Scale <>.
Start ups can fail for many reasons. Lack of funding. Insufficient market opportunity. Poor product fit. But the most tragic source of failure occurs when a company survives all these challenges only to implode due to entirely internal reasons like scaling their operations and technology.
My speech focused on the most tragic, least talked about and all-too common source of implosions: scaling culture.
Some of the topics I covered included:
* The three stages of start up growth: Family (<25 people), Tribe (25-125 people) and Town (125+ people)
* Common reasons why startups can culturally implode: Too much stuff, generalist to specialist, Dunbar’s number.
* Survival tips on avoiding a cultural implosion: Avoid the Right Leaders at the Wrong Time , Set Three Goals Per Person , Keep Placing Small Strategic Bets and Embrace a Mission
I was really amazed all the people I talked with later in the day whose stories reflected these challenges. Some had happy endings. Some did not. Quite a few were happening live. Thanks to IBM, the LAUNCH team and all the great startup leaders I met for the opportunity to share my experiences.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
