CFUnited Presentation Roudup

CFunited was busy for everyone involved so I have no excuse for falling behind in making blog entries as many others just as busy as I did kept up just fine. I'll only post 2 entries for CFUnited this one with all my presentations and then a second one recapping my CFUnited experience (spoiler: It kicked ass!). On with the recap!

Red Green Refactor
PDF Keynote

I was fortunate enough to be given the opportunity to present this topic 2 times at the conference. I feel like both presentations were solid and entertaining; including a reference to old Purple Pants (if you do not know, probably best not to ask :) ). Barney B was disappointed in my lack of gratuitous vulgarity, I'll attempt to not let him down next year. I got really good feedback, even testimonial that TDD does speed up development!

Fusebox Past Present Future (Busy Developers Guide to Fusebox)
PDF Keynote

This was a bit awkward given the current situation surrounding Fusebox and Myself. The first half I did my best to sell on the framework and break down some of the old myths. At about 5:55 I entered my 5th Myth: Fusebox is Dead and instead of really getting into that I made the attendees aware of the current state (at the time) and announced I was resigning. I think spent the second half of the presentation talking about FuseNG (or Fork-a-doodle-doo). Expect more entries soon surrounding FuseNG 1.0 (code named Cuddles).

Code Review and Team Dynamics
PDF Keynote

This started my 3 hour marathon of presenting. It was also a late add to the conference, I was subbing for Jake Munson who was unable to present do to person reasons. I love this presentation, I've given it a few times previous. I felt really good about my delivery and I think everyone got something out of the presentation. I think I might create a new presentation on the same vein but with more emphasis on Team Dynamics and mentoring for next years conferences. I appreciate all the positive feedback from everyone!

Busy Developers Guide to Java Part 1
PDF Keynote

This was one of those presentations with so much content it has to go perfect or you run out of time. I screwed up 2 times and ran over. I was also called Drill Sgt. and Reverend after this presentation. Apparently I was too brash haha! I felt everyone still learn a great deal about java and I got some great positive feedback as well, definitely help enable folks in this one. This was the second session I got to repeat. The second iteration I tried not to preach as much I also pulled some content that might have been too preachy. I ended right on time and had some great interaction, just like the first time. I think this session has great replay potential for future conferences.

Busy Developers Guide to Java Part 2
PDF Keynote

This was my final presentation of the 3 hour presentation marathon. I'll admit that about halfway through the Part1 session I felt ill. This continued into part 2. About half ways through one of the most embarrassing things happened, I had to excuse myself from the presentation for a moment. Luckily this was the last session of the day and everyone was very understanding and allowed me to run over the time and finish the content. I appreciate everyone's patients with me. Aside from the total misery I was in as far as how I felt I think this presentation was awesome. I got good participation from the attendees and very positive feedback from many folks. Anytime I stick around after a session to answer additional probing questions seeking to learn more is awesome.

Overall I had a blast presenting. I hope everyone attending my presentations was entertained and learned or was motivate. As long as I was able to positively affected at least one individual that is all the more I can ask for as a presenter the rest is gravy. Our community is growing and I am glad to be part of the growth. Here's to CFUnited and any other conference that facilitates collaboration and growing! Thanks Stellr for organizing, promoting and kicking ass.

CFUnited Introduction to Java

For anyone attending my Java part 1 session I have checked in all of my sample code to my SVN repo:

http://svn.cfinnovate.com/trunk/presentation-materials/

There are 2 Eclipse projects you will want to download from the repo. I wanted to make this available ahead of time for anyone interested in following along! I'd recommend download it now and then syncing at the conference, download speeds have historically sucked at conferences.

I do not think part 2 will have enough time for much code. Since it is all about JEE environment we'll spend most of our example time exploring the ColdFusion installation (Hopefully you have this already!).

Want to Learn OO?

Last week Ben Nadel posted an entry detailing how to win a free ticket to CFUnited, which rocks. Since I am giving 4 different presentation I didn't figure I was eligible for a free ticket. I resisted posting my anticipated topic, which is probably Living the in Cloud from Sean Corfield (which I will be missing the first time through thanks to my Fusebox presentation) or Thinking outside of the ColdFusion Box. I digress though, in reading the comment stream from Ben's entry (how you enter by the way) I've noticed a pattern that many of the respondents are wanting to learn more about OO. I find this so funny since we've all seen recently how evil OO can be. I have not really weighed in and I will, mostly, not weigh in on that subject. If you choose you would like to learn OO and have not been scared away!

Welcome to the Treadmill

Learning OO is admirable and hard, we've seen this detailed hundreds of times. The world is full folks using the big D word (depends) and many folks on the treadmill known as learning OO. You see learning OO is not a steep learning curve it is a treadmill. You feel like you are getting no where because not matter what you do you really are getting no where. Don't give up on me yet, let's think about this for a second. You don't get on a treadmill to get somewhere, if you do you are indeed a moron. You get on a treadmill to get fit, stay in shape, build stamina etc.. Learning OO does not allow you to build anything new or different than before. Don't think that once you have learned OO you will magically have a different end result. You will not. The end result will be the same, a functional application. Now how it is accomplished will be drastically different but the end result is the same. What the hell does this all mean? Well a couple of things really.


Setting Expectations

Firstly if you want to learn OO just do it. Not just learning OO but give OO it a try and accept what ever comes out*. Remember this is a treadmill, there is no end only more running. If you get tired, annoyed or are otherwise not seeing the results you want get off the treadmill. Try something else for a while, and maybe you can come back and try again later. Next time you try though remember there is no end and learn from what you did last time. Maybe this time you can push yourself harder or dig a little deeper, or maybe now you have a new pair of shoes (but let's face it shoes may help on a real treadmill but typically when I program I don't wear shoes).

Secondly, and this one is a bitch, you can not learn OO in 50 minute increments by listening to community leaders. No matter how great the presenter's OO foo is there will be so much context, back story and other situational circumstances encapsulating everything he/she divulges that you will inevitably misinterpret what he/she is saying at least 40% of the time. If you want to learn OO going to presentations like this is like drinking an energy drink; it is great for a short jittery unfocused burst of learning OO but it typically is no help in long term commitment to learning OO.

Should this discourage anyone from going to these types of presentations? Heck no, just know what to expect and know that you have to focus that energy on 1 concept at a time as you learn. You should also try to learn/attend presentations that are more focused and/or that teach critical thinking skills. While some presentation or practices will not mention anything about OO they will indeed go a very long way in enabling you to learn OO.

Red Bull Presentations

So what presentation might one visit to learn the skills to use to learn OO? You may think oh hows about your presentations on Java. Java is OO that will enable me right? Nope that'll screw you up, bigger than life. Do not go into learning any other language with the hopes of learning how to program OO in another (drastically different) language. That's like trying to kick your smoking habit by increasing the amount of alcohol you consume. Might sound good at the time but it's just gonna fuck you up more in the long run. There are good reasons to learn Java wanting to learn OO in an "OO language" is not one of them.

Design Patterns for ColdFusion that has got to be an enabler right? Nope, sorry it's an energy drink. Presentations like this are good for you if you've been on the treadmill for a bit; you know where your pulse is accelerated but you're still trying to find your rhythm. If you've been playing OO for a while but don't have that background or know a design pattern or 2 but don't quite grasp why or how these design patterns are use these types of sessions greatly help in clarifying and possibly introducing a new design pattern. The reality is it's buck shot, it's a spray of design patterns, if you try to pick them all up you are being unfocused, yep energy drink. Most design patterns warrant their own sessions to really allow the exploration of real life examples on how they solve a problem. Maybe next year we can have an evening of Design patterns with 25-30 minute BOFs (not presentations, BOFs) discussing a single design patter, and have 2 or 3 BOFs a night.

Getting the Tools to Fish

Enough with the what not to go to, you want to learn OO right? At least at first take language out of it, that's what a good enabler will do. These are learned skills that are not specific to a language. Note: I said at first sooner or later language is key to understanding what concepts to even attempt. A Presentation like Design Diagrams for CFCs and Databases is an enabler. This helps you learn the language of OO. What's the point of attending a design patterns presentation if you are not even going to entirely capture the real meaning of some of the words used? The beauty of learning the language of OO and how to design is you don't even have to code to see if your OO concepts you are learning will hold up. If you can diagram you can make a system with pretty cave drawings first and see how well it will work.

Next one of my topics Red Green Refactor. Learning how testing works and why testing produces better code really can empower a person. Beyond improving code this gives you a mechanism to learn anything. I've found, as have others, when I want to learn a new language first thing I do is figure out how to write tests. In respect to OO, what you will find is that Tests, and TDD, allow you to first hand interact with the Objects you create. Its like a UAT for your objects. The theory is if I write a testable object I've written a better object. Sometimes reality begs to differ but at best I've written very nice Objects, at worst I now have tests that will help ensure my API and functionality is the same when I go back to refactor it later. That is pretty empowering and really helps you get off that treadmill of OO for a bit and pick back up later without concern of tripping on your shoe laces.

Lastly, and admittedly this is a bit of a buck shot presentation, John Paul Ashtenfelter's Thinking Outside the CF Box will do just that bring you into a different world that forces you to think differently. I say earlier you should never learn another language with the motivation of learning a concept to apply somewhere else (don't learn Java so you can do OO in CF). That being said learning how other languages operate or how life is made simpler elsewhere can really open your eyes and help you think differently about how you solve today's problems in today's language. Learning concepts elsewhere is a good idea you just always have to make sure you temper those ideas and apply them (or not) in the proper way of the language you are working with at the time, otherwise you end up with interfaces in CFML.

Everything has it's place

I want to stress that all the presentations bring great value to the community. However, you need to know yourself and your comfort level and attend appropriately. Obviously I think learning Java is a great idea but the context/motivation for learning it is not learning OO it is learning it to leverage it in ColdFusion, or learning another skill set to increase you value in the technology community. Presentations on OO or OO concepts like design patterns help re-enforce what you are trying but unsure of, it also may provide the little extra boost of energy you need. Good luck to all that entered (hell the drawing will have happened by the time i publish this) and good luck to all that attend. If they will help please attend my sessions, I hope to see everyone at the bar sooner or later.

*I've shared this story before but my first attempt at OO was back in ColdFusion 6.0 and I cfincluded my first object on the page. I quickly learned how stupid it was to do this and that I really failed miserably at OO but I learned and got better. The key is I just tried and learned, I'm still on the treadmill.

Code Review and Mentoring

I've had quite a few people ask about the presentation slides for my Code Review and Mentoring presentation at cfObjective. I've been intending to post them for a while and I keep getting distracted. I think this is one of my more enjoyable topics. I feel like sometimes technical how-tos are hard to cover in under an hour but Code Reviews and mentoring you can get a good bit of ideas across in an hour. I did not get to go on my Scrum rant this time but 50 minutes is 50 minutes. Thanks to all that attended and my appologies on the delay in my slides.

Speaking at cf.Objective()

Proclaimed to be the only Enterprise level conference for ColdFusion cf.Objective has really stepped it up a notch this year. I am not just saying that because I am speaking there this year I am genuinely impressed by the line-up. The schedule for the conference is amazing, it really does have some awesome presentations that many would consider Enterprise Level (Glassfish, Salesforce integration, BlazeDS integration the list goes on). This will truly be a standout year for cf.Objective(). What am I presenting on? Fusebox, or TDD? nah not for cf.Objective (besides Marc Esher has a sweet TDD preso for the conference). This year I committed to learning more about something for my enterprise level presentations. Don't get me wrong I think I could have given a great presentation on Fusebox, honestly I would kind of like to do a Fusebox BOF, but I really wanted this conference to be an opportunity for me to grow personally and present something fresh and exciting, CFML portlets. So many enterprises have or are moving to portal servers, be it Websphere, Jboss or something else and I have seen a lack of discussion about CFML being relevant in portal solutions. That's not to say it is not happening in the community just seems to be happening quietly. In addition to talking about something fresh for me I get the opportunity to present on something not so new but very close to me and that is Code Reviews and Mentoring.

CFUnited session # 2!!

I know at least one man will be very happy to know I will be presenting Red Green Refactor at CFUnited! I gave a presentation at bFusion about TDD and MXUnit with the same title that got a lot of great feedback. This presentation will follow a similar tone as that one, only less MXUnit and more rants about BDD. I've previously ignored talking specifically to BDD as I felt (and still feel to an extent) that BDD is really just TDD done right. After the recent cfSpec announcement I got to talking to Sean Corfield about BDD and he made a comment of getting BDD over TDD. This leads me to think I should talk more about BDD (it seems to make more sense to more folks). I'm still of the mindset that BDD is little more than TDD done right but, I think BDD is starting to become more relevant as the concepts mature and evolve. I will probably focus more on some BDD concepts than I previously had planned. This should give me a chance to learn more about BDD in the process, I can't wait to give this presentation!

Vote for me! CFUnited

I completely failed to mention CFUnited posted the long awaited survey for session in 2009! Don't forget to check out the details for all the session in the PDF. I've got quite a few topics up this year, including learn Java which I am ultra stoked about folks taking interest in the underlying language of most CFML engines! Of course I could not submit topics without adding one for Fusebox and I figured I'd round it out with a BDD/TDD presentation. The select few that went to bFusion and attended my presentation there can attest to it being a great time. My only regret is I did not submit an OpenBD topic, if you want it you can submit a proposal in the survey so ask for it!!!! I love presenting and I hope I get the vote in, if you haven't filled out the survey get to it.

Speaking @ Mid-Michigan CFUG

It's my pleasure to announce the first of what I hope to be many Open BlueDragon presentations I will be doing for local CF user groups. Rick contacted me a short while backing asking about a presentation and I happily accepted. I was originally (shortly after OpenBD's launch) a little hesitant to do this due to the negative stigma around OpenBD. I think much of that has past plus Railo seemed to be welcomed at UG and I'd like to expect the same courtesy for OpenBD. If your user group has an interest in OpenBD please feel free to contact me, a.haskell on Google's email service. For my limited Fusebox readership that are PHP users if you have a user group I'd love to get an opportunity to show you an open source alternative to PHP. OpenBD might serve you well with some customers that have CFML in house already (not to mention you can still use FB on it!). CFML is an incredibly powerful language and OpenBD gives you a great free alternative. I'll be presenting OpenBD to the Mid-Michigan CFUG on Nov. 11 @ 7pm.

MVCFUG gets to listen to me Rant

With the successful launch of the MVCFUG I am excited to be able to provide content for a local UG. They've asked me to present there next month about Improving Code Quality. Some of you may remember I did a BOF at cfUnited that had a great turn out and this is the presentation that I was going to present at cfDevCon. Unfortunately, cfDevCon had to be canceled but I am excited to share the content stateside with a great group of developers. As an aside this one I think is planned for the evening so folks in Cincinnati should make a trip up, it's just Miamisburg. I am not sure that they are setup to do connect so please don't expect a connect presentation out of it. As with most of my presentations this one really focuses on how we can work together and produce high quality code. We'll most likely focus on peer design and peer reviews. When I say code quality I am not talking about using a structure or queryparam (that is not what a code review is for people!). Really I am not even talking about using CFCs (correctly or otherwise), though they can play into quality. I am talking about how we can work together to create maintainable software that has high fidelity. Talking about code quality is a very passionate subject and I can't wait to share my experiences with the Miami Valley folks!

Speaking at bFusion

Bob Flynn and is once again hosting bFlex and this year has added bFusion! bFusion is an awesome 1 day FREE(!!) event at Indiana University (Bloomington Indiana) followed by a 1 day FREE event for Flex. I won't get into the sales pitch just check out the site. I do want to pimp my 2 sessions though both of which are very near and dear to me. First is Open Source CFML Engines and second being Headfirst TDD.

In my Open Source CFML session we'll explore the open source business model and take a deep dive into how open source CFML engines will help shape the future of CFML development. There is a lot more to Open Source than just the free cost aspect we'll explore this for a brief while. We'll also discuss the differences between Platform and language. I think its just as important to recognize the value of ColdFusion as it is to see the value in CFML. At the end of the session you'll walk away armed with the knowledge you need to make a conscious well informed decision if open source CFML is the right option for you!

My second session, Head First TDD, is pretty much what the title describes it to be. We'll be diving head first into how to start developing with Tests in mind. The cool part is the Head First TDD will be hands on. I won't tell you how you should do TDD you will follow me and work with others and PRACTICE TDD. In the 1.5 hour session there might MIGHT be 20 minutes worth of presentation the remainder of the time will be used to explore TDD together with, hopefully, non-trivial examples. Since this is hands-on and interactive you'll need ColdFusion (or Railo should work), Eclipse, cfEclipse and mxUnit installed. If you'd rather you can just use pulse and get my profile, which I have talked about before. You'll still need to install a CFML engine and have mxUnit's CFML code downloaded and preferably running in ColdFusion. You'll also need an open mind and bring a little extrovert along b/c you will be working with others! You'll also need to download some CF files for the hands on but the examples I have are very boring and I am trying to come up with new ones, ones I have not finished yet. Most likely that will be done the week of the bFusion as I procrastinate and have a lot on my plate. I'll post them as son as I am happy with them.

Welp that's all I have to say for bFusion, I can't wait to see you all there!
