3 Core Java Skills to MasterFor developers, a constant area of focus is refining and building our programming skills. As the rate of change continues to increase there are numerous new technologies and tools to consider. Learning is the constant, mastering core skills - those that transcend context is paramount. This talk focuses on mastering 3 skills essential to Java development. We start by looking at better ways to handle null values. The next topic is checked exceptions. While they often get a bad rap, we examine cases where they add clarity to APIs. We conclude with exploring reducing code complexity by using enums enhanced with lambda expressions, a simple implementation of the strategy pattern.
A little bit of Caffeine and a whole lot of TrustIt's one thing to trust others, but do you fully trust yourself? Are you acting in your own best interest when it comes to your career? Your answer may surprise you.
Agile Product Management?Agile Software Development techniques are the foundation of how most modern software products are developed. How relevant are these techniques to how software products are conceived, improved, marketed, sold, implemented and managed? In a development environment where we value responding to change over following a plan, how does product vision and strategy dovetail with responding to a fast-paced and competitive market? Also, what's the difference between a Product Owner and a Product Manager? What's the relationship between a Product Roadmap and a Product Backlog? In this session we will discuss what successful Product Managers do in an Agile environment and what rules you should bend or break when it's bad for business.
Be a Professional Developer and Write Clean CodeProfessional developers must write the best code possible, given what they know and what they have at the moment of writing. After a while, we may look at that code and wonder "wow, what was I thinking?", and that's a good thing: it shows we have improved. This session is about my observations regarding code I either wrote or had to work with.
Beyond the Daily Stand-up: An Intro to ScrumCountless companies believe they're doing Scrum because they have 30-minute daily stand-ups (with people sitting and staring at their laptops) every morning. But Scrum is really a lot more than that. In this session, we see all of the main parts of Scrum (roles, artifacts, and events), and we also talk about some real world collaborations in teams who adopted Scrum.

Explaining Agile with 140 billion gallons of water.Are you new to Agile? While the agile concepts may sometimes be easy, the why's and how's are a little trickier to wrap your head around. The most interesting way I've found to talk about these why's and how's of Agile, is in the context of a natural disaster that Houston is very familiar with -- flooding. I've unfortunately participated in two recent rising flood water events and employing my agile skills has had a profound impact on the "success of the project". So if the goal (product) from participating in a flood is to maintain a certain lifestyle level after the event, then the deadline is when the water is in the house. This makes the backlog the household inventory to save, which needs to be prioritized. As the water encroaches on the house, it makes sense to regularly check the radar and conditions and assess the work completed, the process, and next course of action. This is called an iteration or sprint. If the whole family knows the goal of the iteration, like all fabric furniture needs to off the ground, then the adults can lift the beds and the children can tackle the chairs. This is a self organized team. If the children say something is too big or heavy to lift, they are blocked and let the team know that they need help. Typically in non critical circumstances, this would happen daily during a standup meeting, where the entire team shares their accomplishments, daily goals, and blockers, but given that imminent flooding is indeed an emergency, the standup portion of this analogy will be skipped. Along the way, small things might be discovered that can greatly improve the situation, like locking the doors to prevent the water pressure from pushing them open. These minor improvements are called kaizen. Finally when the water has receded, the last task is a retrospective, where acknowledgements of the good parts and ideas to improve bad parts are shared.
From the Closet to the Cloud! Physical to Virtual Migration of Linux Systems and ServicesThis presentation will cover the migration of a personal CentOS 5 based Dedicated Server to an Ubuntu 16.04 Virtual Machine running in Microsoft Azure. It all started around six years ago in college when I asked a presumably simple question, “How can I run my own website on a server?”. I was able to acquire a server hosted in Michigan where I began to develop and deploy a variety of websites and services ranging from profitable internet domains to offsite archival of home security footage. There were hiccups along the way including a tech forgetting to plug in my hard drive after requesting a RAM upgrade, losing days of service uptime when requesting a second hard drive, and ultimately discovering that my server host had been acquired and would be shutting down all hosting services. This session will focus on how I was recently able to move everything successfully from the physical drives of that particular system into a Virtual Machine that is scalable on-demand, backs itself up on a user-defined schedule, and even allows for white-label deployment using a base image. There will be much to learn regarding differences in colocation vs cloud hosting, CentOS vs Ubuntu, and configuration of common services such as apache2, drbd, vsftpd, and squid in Linux environments. If you have an interest in general server operations / administration and have wondered about the benefits of the cloud, this session will offer insights and opinions to assist in understanding why cloud is a powerful modern mechanism for server deployment. faster, speedup time to market, and reduce overall cost. In this session we will give you an overview of Azure Functions from introduction to application. We will walk through real world examples of how this cloud service can help you replace and extend networked functionality without the overhead or maintenance of a full-fledged server.
Hacking Networks Made Easy - Finding and Fixing Low Hanging FruitOften times hackers don't need a super 1337 exploit to compromise a network. What's the point of remotely exploiting a box when you can just guess the password, run a common attack, or utilize an employee's rogue backdoor? In this talk, we will discuss and demonstrate how to find the low hanging fruit that can lead to full compromise of the network and what can be done to detect and protect against them. This presentation will provide you with actionable items for your red and the blue teams that that can be started immediately without spending any additional money or purchasing any tools. You will also leave with the understanding that the blue team may benefit from taking a step back and focusing on improving their initial security posture.
How Not to Destroy DataCRUD apps destroy data. Delete is an obviously destructive operation, but Update is no better. Updates overwrite the data that was once present. What would software look like if the only valid operations were Create and Read? Historical Modeling is a technique for designing and building software systems that permit only inserts, no updates, no deletes. The only way to "modify" an object is to insert related records. You can then read the state of the object by querying for the presence or absence of those related records. We'll start with the assumption that all records are immutable and indelible. From there, we'll build a set of patterns that yield some surprising benefits. With a historical model, synchronizing disparate nodes is trivial: just insert what you don't yet have. Building offline-first web applications is easy. Viewing a snapshot of the system at any point in the past is a simple query. Let's build a historical model together, and see these benefits for ourselves. Let's put aside the assumptions of CRUD applications and discover a whole new set of patterns. Once you master these techniques, you will never destroy data again.

So what can YOU do with a $2 computer?Cloud. Scale. Big Data. Machine Learning. Everyone's talking about the high end. Even IoT seems to imply needing a big cluster of servers to work. But Moore's law doesn't talk about scaling up. it just says the same capability halves in price every 18 months. And that makes the low end of computing VERY interesting these days. In this session, we'll look at what's possible with a computer you can get for under $2 in volume (and a few that cost just a bit over that point). And I think you might just be amazed at what you can do today for under the cost of the cheapest cup of coffee you can get at Starbucks.
SQL Server Tips from the FieldMicrosoft SQL Server is gaining more and more market share.

We will take a look at the evolution of the software industry and how we have lost some of the skills needed to achieve amazing results. This talk is independent of language, and we will be using multiple languages in the examples. We will then dive into a complex series of solutions as a group, and start bringing back object oriented analysis and design.
Top 5 common agile estimation mistakesAs part of becoming a Senior Software Engineer, I have been trusted with the development of a new feature from scratch, and as exciting as this sounds, it also evidenced how hard is to come up with spot on estimations in agile. In this session i'd like to expose my top 5 common mistakes when creating estimations and how to avoid them.
Trust Fall : Creating Teams that TrustNothing improves a team like trust. Teams which trust one another can conquer more problems, more quickly, because less time is lost to friction. Teams which are trusted by the business are capable of creating substantial change within their organizations. In short: Trust Changes Everything. But how do we create trust? We all know that just putting a group of people together does not mean they will trust one another. Some will say it comes with time, but it certainly isn't guaranteed to come with time. But there are ways that teams can be deliberate about creating trust. There are skills which they can learn and practice which will engender trust, not from manipulation but from vulnerability. Your teams can be much more successful, and your life on them more fun and engaging, if you help them develop trust first, and software second.
