Preview - Elliotte Rusty Harold to Visit ACGNJ Java Users Group

I am happy to announce that Elliotte Rusty Harold will visit this month's ACGNJ Java Users Group to present, "Exceptions: I'm Telling You for the Last Time" on Tuesday, April 11, 2017 at the Scotch Plains Rescue Squad (second floor) starting at 7:30pm.

No feature of the Java programming language is as original or as misused and controversial as exception handling. More than twenty years after Java was introduced more developers don't understand exceptions than do. That's not surprising given that most textbooks and tutorials get exceptions seriously wrong by focusing on the rules you must follow rather than the reasons you should follow them.

And yet just three rules cover 99% of what you need to know about exceptions:
Separate exception handling from the main path by making try blocks as long as possible.Use checked exceptions for environmental problems and runtime exceptions for programming errors.Bubble exceptions you can't handle. Follow these simple pr…

Summary - Trenton Computer Festival 2017

The 42nd annual Trenton Computer Festival (TCF) was held on Friday, March 17 (TCF IT Professional Conference) and Saturday, March 18 (regular show).

At the TCF IT Professional Conference, I presented "Building Realtime Data Apps with Speedment."  Many thanks to Per-Åke Minborg, CTO of Speedment, for his support.

My schedule allowed me to attend only the morning sessions of the conference.  I attended the following talks before and after mine.

Andrew Murran, Senior Cyber Security Engineer with Sila Solutions Group presented "Rebooting Software Development."  He focused on the philosophies of why developers choose the path of least resistance to ultimately write poor, therefore less secure code.  Andrew also demonstrated that it is possible to change that path of least resistance to write good, quality code that is more secure.

Howard Deiner, a software consultant and educator who specializes in Agile process and practices, pres…

The topic for this month's meeting is "Technical Overview of Functional Programming" presented by Barry Burd.

Abstract:
This presentation is an overview of the concepts typically used in functional programming.  These concepts include pure functions, immutability, referential transparency, pattern matching, lambdas, currying, sections, map, filter, fold, list comprehension, lazy evaluation, higher-order functions, polymorphism, and monads.  Some of these concepts are the basis for features in Java 8, but many aren't.

Please contact me if you have any questions and I hope to see y'all on April 26!

Summary - Day Two of Philly ETE 2016

Day Two of the 2016 Philly Emerging Technologies for the Enterprise Conference kicked off with the keynote address by Raffi Krikorian entitled, "How Your Organization is Killing Your Software."

Raffi discussed certain aspects of software development such as speed of development and major rewrites of code by recalling his experiences while working at Twitter.

His five stages of code rewrites are:
ElationBuckle DownOh SHIT!ExhaustionRelief One of his main take-home messages was the importance of establishing your team.  He stated, "Setting up your team says more about your architecture than the architecture itself."

This was indeed a very engaging keynote address.

The sessions I attended are summarized as follows:

Session One:
"An Introduction to Web Components and Polymer"
Jeff Posnick

Jeff introduced Web Components and its four specifications:

Summary - Day One of Philly ETE 2016

Day One of the 2016 Philly Emerging Technologies for the Enterprise Conference kicked off with the keynote address by David Ferrucci entitled, "AI: A Return to Meaning."

David's main message was related to meaning, that is, meaning in not explicit in language.  Making decisions based on statistical data versus deductive reasoning isn't easy.  David maintains, "We need machines to go beyond their words and their patterns.  We need them to understand."

This was indeed a very thought-provoking keynote address.

The sessions I attended are summarized as follows:

Session One:
"React.js Reconciliation"
Jim Sproch

Jim provided a very nice introduction to React Reconciliation and its underlying design of the virtual DOM.  He juxtaposed how an existing paradigm, such as rebuilding the DOM with every UI change, can be made more efficient.  For example, the traditional approach of synchronizing the UI with the DOM has a complexity of O(N3).  However, the React…

Let's Get Philly ETE Rockin'!

I arrived a short while ago at the Society Hill Sheraton in Philadelphia for this year's Emerging Technologies for the Enterprise (ETE) Conference.

I've been fortunate to have once-again served on the Steering Committee for this year's event as one of the handful of industry folks who are not an employee of Chariot Solutions.  It's an absolute blast working with everyone!  Chariot Solutions is the most gracious host!

There are keynotes both today and tomorrow...

This morning's keynote will be delivered by David Ferrucci and is entitled, "AI: A Return to Meaning."

For detailed information on all the talks at this year's conference, please visit http://www.phillyemergingtech.com/.

That's all for now...stay tuned for highlights of Day One!

2015 Emerging Technologies for the Enterprise

The 2015 Emerging Technologies for the Enterprise (ETE) Conference will be held on Tuesday and Wednesday, April 7-8, 2015 at the Society Hill Sheraton in Philadelphia, Pennsylvania.

I have been participated in this conference since 2008 as a speaker and steering committee member.

The conference is run by Chariot Solutions based in Fort Washington, Pennsylvania.  I've known some of the employees since 2006 and it's been an absolute pleasure working with them.  They treat me like a member of the Chariot family and it is certainly much appreciated!

I wish I could say that there is still time to register for this event, but it has been sold out since mid-February, so you will have to wait until next year.  In the meantime, you can peruse the ETE web site for the keynotes and sessions that will be available this year.

I'll be tweeting these next few days and blogging about my experience.  Please look for my tweets with the #phillyete hashtag at @mpredli.
