How to use Geolocation
in your web app

Rafﬁ Krikorian, Twitter @rafﬁ
Future of Web Apps, Dublin, 2010

People want to talk
about where they are

People want to discover
what’s around them

Location is -

Globally applicable,
locally relevant

When people think of location,
they think of a place

Sometimes the actual place
doesn’t matter

What makes a place?

Re-architecting a system is wrought with problems: * We almost always underestimate the difficulty of said task * We almost never completely understand our customers’ needs * The system almost always changes out from underneath us However, what we can sometimes forget is the most important aspect of any project: the team! Your team, who miraculously survives these projects, has to continue to change with your business and your technology! But, don’t fret, we can architect our way towards this way of thinking! Let’s figure out how to be resilient and adaptive with the help of each and every team member. Ignore re-architecting your team at your own risk!

Re-architecting on the Fly #OReillySACon

Raffi Krikorian

The decision and process behind rewriting or re-architecting a system is often plagued with a series of problems: people always underestimate the complexity, people never fully understand the customers, system requirements constantly change out from under them, and, in almost all cases, it takes much longer than anybody can predict. As part of this workshop, we’ll look at a couple of case studies of re-architecture to gleam strategies of success from them as well as common pitfalls to avoid. This workshop should arm you with a framework by which to approach your own decisions around how to manage, maintain, and evolve your own systems: * understanding the underlying motivations; * developing a method for deciding whether to evolve or to rewrite; * managing the engineering effort of re-architecture in the midst of a changing business; * setting up metrics to understand whether you’re on course; and * organizing the engineering team and the culture to ensure success

In this session Raffi will be discussing what companies are doing right now with geo and where they are being most successful. He'll also take an in-depth look at the privacy concerns and UI implications, along with what users actually want from geo-enabled apps and where the opportunities lie in the future.

Presenter: Todd Marks, President, Mindgrub Technologies Summary: Imagine walking up to a store and having the store's hours, prices, and specials delivered right to your mobile phone or device. Sitting in front of a computer searching for information is old. The paradigm shift is “now I’m here, what information is around me?” viaPlace is twofold: a registry system that mirrors a domain registrar which allows for the delivery of advertising, entertainment and education to an end user based on their geographic location. With over 3 billion people worldwide using mobile devices its clear location based services, marketing and advertising is the next hottest trend.

Location based Services have entered the mainstream. Personal Navigation Devices in cars are ubiquitous and personal navigation on the phone is already a big business. Nokia alone is going to have over a hundred million GPS enabled devices across the whole product range in the market by 2010, challenges like battery live and slow positioning technology have been solved to a satisfying extent. Now Location based services are about to get social, considered by some as the holy grail of LBS. Everyone is in the starting blocks to grab a piece of the pie, innovative start-ups, the operators with millions of customer relations and the handset manufacturers who put the ultimate gateway in our hands. And why are the big ones like Facebook missing the train so far? What is the ecosystem going to look like and how do we overcome major obstacles including privacy, signal vs. noise and user experience on the fourth screen? Felix Petersen is giving his perspective on things, both as co-founder of one of the pioneering startups in this space and as an employee of the dominating handset manufacturer aggressively pushing towards a vertically integrated end user experience.

Handling Real-time Geostreams

Raffi Krikorian

Twitter has launched a Geotagging API – we really wanted to enable users to not only talk about “What’s happening?” but also “What’s happening right here?” For a while now, we’ve been watching as users have been trying to geo-tag their tweets through a variety of methods, all of which involve a link to a map service embedded in their Tweet. This talk will delve into how Twitter handles their geocontent including tool suggestions. As a platform, we’ve tried to make it easier for our users by making location be omnipresent through our platform, and an inherent (but optional) part of a tweet. We’re making the platform be not just about time, but also about place.

Adding the "Where" to the "When"

Raffi Krikorian

Social applications have been venues for people to converse, emote, and share -- and in those applications, "when" has always been inherent and well captured, but the other contextual signal, "where", has been (usually) conspicuously missing. Location, when taken into account, can provide rich signals to help understand social connectivity whilst helping to discover and surface content. Numerous devices and infrastructure services have the ability to expose location, but comprehending how to best make use of these technologies can be complex. Additionally, after the infrastructure is put in place, the next hurdle to overcome is understanding how to create a useable location-based feature that users can comprehend and love while also feeling safe and secure. This session is targeted to those who want to learn about these technologies, and to those who want to understand how to think about their users' needs, their security, and their privacy. We'll also review web and mobile services that have been designed with location at their core, or location as a feature. And, finally, we'll talk about how Twitter thinks about adding "where" to our "when".

WattzOn @ ETech 2009

Raffi Krikorian

It is clear that the lifestyles of the western world have become unsustainable. Fossil fuel scarcity and global climate change are threatening to cause great economic and environmental damage to the world. Individuals have been looking for ways to understand their contribution to the global and local energy stages, and make better decisions to reduce their impact. WattzOn.com is providing users with an online tool to calculate, track, compare, understand, and budget their personal energy consumption – much in the same way they would manage their finances. In doing this, WattzOn also strives to innovate on the tools currently available for personal energy tracking. The status quo on personal impact tools involves online “carbon calculators,” which are already ubiquitous on the Internet. However, these calculators suffer from fundamental flaws that prevent them from becoming an effective tool for change. First, they are static and therefore do not react to improvements in knowledge or allow the addition of data. They are also “black box” in operation and do not clearly show a user how their energy numbers were calculated and what assumptions were made. Finally, they have a singular focus on carbon emissions, which doesn’t fully characterize power usage independent of fossil fuels. WattzOn changes this by providing the entire community with a collaborative environment to understand and manipulate how the numbers are calculated, while also shifting to a more comprehensive paradigm by tracking total power usage in watts. The WattzOn back-end is powered by a pretty unique database nicknamed “holmz” – holmz is a structured wiki-engine that allows people to not only manipulate and share text, but also lets people collectively edit structured data and workflows. With holmz, WattzOn users can debate how much energy goes into, say, growing an apple; separately debate how much energy is needed to transport the apple to a local grocery store; and then have another set of people combine those two together into one result: the energy cost of an apple. Finally, that data propagates through the system, updating the total watts calculated for people with profiles indicating that they eat apples. The crowds can collaborate on getting all the individual parts of the equation correct so that everybody many benefit. WattzOn is currently a global tool with assumptions made on a national/statewide scale. However, the ultimate goal of the system is to be able to accurately understand the exact power needs of a user’s lifestyle. Given differences in distances from product sources, weather, population density, and transportation options, the impact of any decision will be dependent on the location of the individual. By allowing users to populate the database with information from their own lives (either manually or passively by linking to online bills), the accuracy of the calculations will improve. Once this detailed database exists, anyone will be able to run specialized queries and create clear graphics to illustrate power usage of various communities and groups. By giving individuals a tool to clearly visualize how they are “spending” energy, we hope that they will take measures to lessen their impact on the world, ultimately spurring widespread energy reduction in our society.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
