Cut your Dependencies with - Dependency Injection for South Bay.NET User Grou...Theo Jungeblut
Dependency injection is a design patter with the potential to write cleaner code. Over the lifetime of a product, maintaining the product is actual one - if the the most - expensive areas of the overall product costs. Writing clean code can significantly lower these costs. Writing clean code also makes you more efficient during the initial development time and results in a more stable code base.
In this talk, we will dive into the basics of Inversion of Control (IoC) and Dependency Injection (DI) to review different ways of achieving decoupling. We will explorer best practices, design, and anti-patterns.

Runtime Monitoring of Component Changes with Spy@RuntimeMario Sangiorgio
Spy@Runtime is a tool that monitors component changes at runtime using two behavior models. It recovers specifications during design time and detects changes at runtime. The protocol behavior model captures general interaction protocols while the behavioral equivalence model precisely describes behavior within a narrow scope. At runtime, Spy@Runtime monitors applications and services to detect violations by comparing execution traces to the protocol model and interpreting violations using the equivalence model.
The document describes an approach for programming by imitation that allows programmers to synthesize "glue code" to integrate new features into an existing system. It works by recording executions to create traces, analyzing the traces to identify framework and plugin code, and then synthesizing code that imitates observed framework behavior to integrate new features. Programmers provide demonstrations of desired features, and the system generates code that integrates the features by matching against a database of complete application traces.
Growth and Arrogance vs. The Power of a Customer Centric Culture
Every fast-growing organization experiences growing pains. The most difficult and complex challenge for leadership is maintaining an excellent experience as the business scales. Customer centricity is easy for a small startup; the company’s founders are often intimately involved in every key customer engagement. However, when meeting sales quotas, achieving profit margins, and running your business by the metrics becomes more important than delighting your customers, you stop hearing about customer complaints simply because you don’t see them anymore, and your entire business is at risk. Your customers become easy targets for the competition and your positive momentum in the market slows.
In this session, Art Papas shares his journey as founder and CEO of Bullhorn—a company that has grown extremely rapidly to more than 500 employees and nearly $100 million in revenue. He’ll discuss how he refocused his company’s culture back on customer service after facing a similar struggle, and how leaders of organizations can leverage his hard-earned lessons to position their businesses for long-term growth. This session will offer actionable takeaways to help attendees create an incredible customer experience within their own organizations.

When Does Your Company’s Identity Matter?
How do you create a visual identity for your business when a sense of style isn’t in your DNA? This was the challenge faced by the founders of RJMetrics, who set out to disrupt an industry where appearance is everything. CEO and co-founder Bob Moore will step through the evolution of the RJMetrics brand from attic startup to SaaS powerhouse. The lessons learned along the way go far deeper than just pixels on a screen.
The document discusses common myths about starting a startup business. It addresses three myths: that building a startup takes too much time and will be exhausting; that starting a business requires a lot of money; and that one's day job may consider their startup a threat so it's best to operate in stealth mode. It then briefly mentions that the author will discuss three things they did in 2016.
If ‘hustle’ and ‘Glengarry Glen Ross’ are synonymous to you, you might think this talk won’t be that relevant. You’d be wrong.
It’s fashionable to think that sales are the result of Inbound marketing in some circles – perhaps every sale you make comes to you magically through the Internet with no human touch. Does that mean you can’t do better? Steli has accelerated sales in some of the fastest growing Silicon Valley startups as well as growing his own SaaS business, Close.io. He will offer some proven techniques to grow your sales revenue and improve your sales processes. You can apply many of the same ideas to get things done in your own organization, regardless of your role. As Dan Pink said, ‘To Sell Is Human‘.

Current Approaches in Search Result DiversificationMario Sangiorgio
The document discusses current approaches to search result diversification. It defines diversity as providing both relevant and diverse results to ambiguous queries. Diversification aims to optimize relevance and diversity through measures like semantic distance, categorical distance, and novel information. The tradeoff between relevance and diversity makes the problem NP-hard. Common objectives include maximizing sum or product. Evaluation benchmarks adapt existing metrics or use datasets with ground truths. Open issues include defining new diversity types and integrating diversity earlier in the ranking process.
Debugging,Troubleshooting & Monitoring Distributed Web & Cloud Applications a...Theo Jungeblut
In the past, applications where created as monolithic entities running on a single server. If this is the past for you, too, you will have experienced the downside of modern distributed and cloud applications, as debugging, troubleshooting, and monitoring is not easily accomplished with traditional approaches.
Within this session, we will explore different possibilities for collecting and analyzing the needed information to solve issues on modern distributed application and discuss the advantages and disadvantages of each approach like debugger, log files, performance counter and third party solutions. The focus of this session will be on Developer and DevOps need, as increased release cycles and third party dependency more and more result in the need for troubleshooting also on production system, rather than in an isolated test environment.
This session requires a solid understanding of distributed applications and knowledge of SOA, but most principles also apply to and can be beneficial for more traditional application design approaches. The used code examples are in .NET but the shown principles generally apply to other languages, too, and shown software is often available for a variety of environments.
The document provides an overview of the Rest.li development workflow. It describes implementing a simple REST request to retrieve a fortune and outlines the key steps: 1) Write a data schema, 2) Write a REST resource, 3) Write an asynchronous client. The resource and client are modified to use ParSeq for asynchronous and non-blocking request handling by returning and composing tasks. This allows for improved scalability and parallel request processing.

Managing Machine Learning Projects in Industry: As the use of machine learning techniques to analyze and find value in ‘big data’ is being adopted more broadly by industry, we see an increasing need to build teams that can execute on large and complex projects. It is not possible for a single machine learning expert to cover problems of the scope and magnitude that are encountered. The scale of these projects requires teams of researchers and engineers to coordinate and collaborate to deliver impact. In this talk I will touch on some learnings and considerations when building or expanding such a team. I will cover building a group, framing the problem, finding a solution, and evaluating the results. I will illustrate the points with examples drawn from my experience in large companies and startups. I hope to provoke consideration and discussion for the challenges in this area, as well as to illustrate some of the complexities.
High Performance Software Engineering TeamsLars Thorup
Based on my experiences building high performance engineering teams, this presentation focuses on the technical practices required. These practices centers around automation (build, test and deployment) and increased collaboration between Engineering and QA (TDD, exploratory testing, prioritization, feedback cycles).
You’ve likely heard of Intel Corp’s mindfulness training for 100,000 global employees. Maybe you know that Google, Aetna, General Mills, Goldman Sacks and many other companies sponsor mindfulness programs for their workers. You might be experimenting with a mindfulness program at your own company.
In this direct and personal talk, Matthew Bellows explains why. Drawing on 25 years as a meditator and 20 years as an entrepreneur, Matthew links mindfulness and work in a way that makes clear why training in this skill is so helpful for managers in the 21st century.
Kristine Woolsey is a behavioral strategy consultant who advocates applying behavioral science principles to design workplace environments and strategies. She discusses B.F. Skinner's view that controlling behavior through environmental changes that benefit all can eliminate coercion. Her CORE PRIME model involves analyzing the current environment, stakeholder needs, and strategies versus the desired future state. She cites research showing that diversity improves creative problem solving. Her case studies at companies like PCA Skin found that relatively minor changes to the physical workspace and compensation structures significantly improved productivity, relationships, and business outcomes over several years.

In today's dynamic and competitive market, a well-rounded skillset is no longer a luxury - it's a necessity.
While technical expertise (hard skills) is crucial for getting your foot in the door, it's the combination of hard and soft skills that propels you towards long-term success and career advancement. ✨
Think of it like this: Imagine a highly skilled carpenter with a masterful understanding of woodworking (hard skills). But if they struggle to communicate effectively with clients, collaborate with builders, or adapt to project changes (soft skills), their true potential remains untapped. 😐
The synergy between hard and soft skills is what creates true value in the workplace. Strong communication allows you to clearly articulate your technical expertise, while problem-solving skills help you navigate complex challenges alongside your team. 💫
By actively developing both sets of skills, you position yourself as a well-rounded professional who can not only perform tasks efficiently but also contribute meaningfully to a collaborative and dynamic work environment.

Parabolic antenna alignment system with Real-Time Angle Position FeedbackStevenPatrick17
Introduction
Parabolic antennas are a crucial component in many communication systems, including satellite communications, radio telescopes, and television broadcasting. Ensuring these antennas are properly aligned is vital for optimal performance and signal strength. A parabolic antenna alignment system, equipped with real-time angle position feedback and fault tracking, is designed to address this need. This document delves into the components, design, and implementation of such a system, highlighting its significance and applications.
Importance of Parabolic Antenna Alignment
The alignment of a parabolic antenna directly affects its performance. Even minor misalignments can lead to significant signal loss, which can degrade the quality of the received signal or cause communication failures. Proper alignment ensures that the antenna's focal point is accurately directed toward the signal source, maximizing the antenna's gain and efficiency. This precision is especially crucial in applications like satellite communications, where the antenna must track geostationary satellites with high accuracy.
Components of a Parabolic Antenna Alignment System
A parabolic antenna alignment system typically includes the following components:
Parabolic Dish: The primary reflector that collects and focuses incoming signals.
Feedhorn and Low Noise Block (LNB): Positioned at the dish's focal point to receive signals.
Stepper or Servo Motors: Adjust the azimuth (horizontal) and elevation (vertical) angles of the antenna.
Microcontroller (e.g., Arduino, Raspberry Pi): Processes sensor data and controls the motors.
Potentiometers: Provide feedback on the antenna's current angle positions.
Fault Detection Sensors: Monitor for potential faults such as cable discontinuities or LNB failures.
Control Software: Runs on the microcontroller, handling real-time processing and decision-making.
Real-Time Angle Position Feedback
Real-time feedback on the antenna's angle position is essential for maintaining precise alignment. This feedback is typically provided by potentiometers or rotary encoders, which continuously monitor the azimuth and elevation angles. The microcontroller reads this data and adjusts the motors accordingly to keep the antenna aligned with the signal source.
Fault Tracking in Antenna Alignment Systems
Fault tracking is vital for the reliability and performance of the antenna system. Common faults include cable discontinuities, LNB malfunctions, and motor failures. Sensors integrated into the system can detect these faults and either notify the user or initiate corrective actions automatically.
Design and Implementation
1. Parabolic Dish and Feedhorn
The parabolic dish is designed to reflect incoming signals to a focal point where the feedhorn and LNB are located. The dish's size and shape depend on the specific application and frequency range.
2. Motors and Position Control
Stepper motors or servo motors are used to control the azimuth and elevation of
