Windows Communication Foundation – Getting Started – Developer’s Meeting

August 19, 2010 DevMeeting, Presentation, Success, WCF 1 comment

Hello, today I performed presentation on Windows Communication Foundation and it went extremely well. People were interested in topic and it smelled in the air.

Why am I happy with this meeting?

People were listening very-very attentively! It is the best gift to the speaker. Many thanks to today’s attendees! You made this presentation awesome!

What was the agenda?

For today I planned to have “Getting Started” session, where I decided to talk in general what is WCF and then proceed to basic concepts of it, like ABC.

In DEMO 1 (Damn it! Let’s write some code!) I created ever simplest WCF library and simple Contract that exposed todo list functionality. Then I brifly showed configuration and we started wcftestclient.

In DEMO 2 (Damn it! Let’s configure it!) I talked a lot about endpoints and how we can configure them. After I created a lot of them it was highlighted that changing the way how our service works by configuring and not changing the code is the key feature of WCF. WCF is indeed unified framework that allows us has one logic, but different exposing to the real world.

In DEMO 3 (Damn it! Let’s use & host it!) I created very simple console application that was able to send todo item to the service. It went with some exceptions thrown into console, but people liked it and besides after that I created SuperTodoServiceClient and it worked well. Also we voted were do we want to host our service for the long time. Most decided to host it under IIS. Till the actual hosting all went well, but then suddenly it didn’t work under IIS. Reason was very simple – since my machine has brand new OS, IIS was not configured properly.

What’s next?

Also I’m planning to have another meeting on the WCF. This time it will be “Advanced”. In that session I would like to show some real-world examples. Also I’m going to prepare to the 70-503 exam (on WCF), so I might get some interesting topics from the training kit to show on the meeting.


More and more I start disliking ppt files. But anyway to have some visual appearance of presentation I created ppt file (maybe finished with it at 5:30 am so don’t kill me if it is “poor”). Btw, having ppt has some plus – I can put my blog’s logo and URL :)

Guys, looking forward to hear from you! Will appreciate any of your comments.

Developers Meetings Survery – RESULTS

August 6, 2010 Coaching, DevMeeting, Presentation, Success 2 comments

Few days ago I started survey about improvements to Developers Meetings inside of my team, but I also announced it to anyone who can be interested in this via twitter and blog.

Top areas of interest are:

  1. *Foundations like WCF, WPF, WWF and huge parts of .NET development like WinPhone
  2. Design Patterns either Gof, Enterprise or not commonly known
  3. Core .NET (concurrency, memory, security)
  4. New features coming in .NET

 More details:

Top voted topics are:

  1. Enterprise Design Patterns
  2. WCF
  3. Gof Design Patterns with live code
  4. Estimation
  5. Refactoring
  6. TDD

My thoughts on top topics:

Because I’m not expert in Enterprise Design Pattern, it would take time for me to have some presentation on it. Either I will ask one of my colleges, who already read  “Patterns of Enterprise Application Architecture“.

I just scheduled Developers Meeting on WCF for my team, and I see this to be “getting started” meeting where I’m going to talk about main concepts and basic usages. I’m going to implement some funny example.

Regarding GoF Design Patters with live code, that should be very easy for me. I already have a whole bunch of different examples on my blog, so I can use them and talk on them. I expect to have junior stuff on those meetings. I would like to train my capabilities in coaching.

Estimation should be meeting where I would like to talk around Fowler’s estimation deadly sins.

Refactoring could be divided in many meetings, like core refactorings but with live code and also “refactoring to patterns”

TDD – no slides. I remember when we had presentation on TDD for devs and it was with slides. I think that is the worst way to explain TDD. Yeah, might be that it is good to show flow diagram, but I vote for code.


Improvements section:

What is the most interesting about improvements is that people would like to see more real code. Hm, this should mean that either people are tired because of my simple “hello world” examples, or either they are very interesting in how we can use those things withing complex project, and maybe they are right, because “hello world” examples could be found easily over internet.

Details on improvements:

Also as you can see we’ve got 3 comments on improvements. First one says to view presentations before meeting. I would agree with this, but maybe I will work on more detailed agendas, which will be sent exactly before meeting. Please let me know if this is ok.

I’m really looking forward to provide lot of interesting information to my co-workers and work along with them to build solid and very knowledgeable base for our growth.

Will appreciate if you would share your thoughts on this results and thank you very much for participating in survey!


Developers Meetings Survey

August 4, 2010 Coaching, DevMeeting, Presentation No comments

As you might know, I’m keen on delivering technical meetings for my co-workers within one business unit in company.

It is very important to keep developers working on their knowledge and that is what my company is trying to do. It organizes special seminars on different topics for all of the offices, it also creates its own certification model to evaluate knowledge of employees, etc. , but before that all started my team had our own technical meetings called “developers meetings”. Those were providing by one smart guy, who has moved to another country, but since team felt sad about that we continued having developers meetings, so we proceeded with scheduling topics and assigning people to them.

Fun, but while it was like official, conference room was full of people and everyone was listening to junior talking on some design pattern. As I think everyone got disappointed by such meetings, but I do not say that this was bad idea to have junior talking on patterns. Turns out it has something good inside, because that person learns something for himself and trains to present. Sad but true, he is not able to deliver something properly to the big audience.

I know this, because I also was in role of such presenter, talking on Prototype without clear understanding of it and using sophisticated example from book of GoF – I simply did not understand it and I’m sure that none get something valuable for him/herself out of that talk.

My conclusion is that presentation should be delivered by person, who has really solid understanding of things he talks about. If it is small team and it contains juniors, he should start with ever simplest code. But since anyone should start with something, junior also should have presentation sometime. In this case I would recommend to make presentation for limited number of people, like other starting developers and few experts who are really interested in people growth.

Back to Developers Meetings we are having now, I really would love to see them thriving, but it requires investment of time from interested people. These months I’m trying to deliver presentations more often, and since we’ve got lot of new staff we can repeat old topics with new breath. How to know if developers want those meetings again?

To get some feedback I created survey, which I sent to my co-workers, but I would be really happy if you, my readers, will fill-in it also. (It shouldn’t take longer than 1 min.)

Developer’s Meeting: AutoMapper

July 22, 2010 AutoMapper, DevMeeting, Presentation, Success 12 comments

Today I performed developer’s meeting on AutoMapper. I would say that it went good, but I did not really enjoy it and will explain why. But I do not regret doing this presentation and will explain why.

Why am I upset of today’s presentation delivery?

Not so many people got interested in theme, that I’ve decided to present. There were about 10 or less developers in conference room. I really expected to have bigger audience and had prepared to speak to other division of our software business unit. But I believe there are some reasons why I did not get many listeners.

Few important thoughts for presenters that encounter the same

Never be disappointed by the number of attendees.. at least at the beginning, so this will not decrease quiality of your speach.

If topic of you speech is not really popular it doesn’t mean that you should discount its value.

If topic is indeed simple don’t neglect your preparations. For some reason I even wasn’t a bit nervous before presentation, as I’m usually are and I don’t find this to be good.

Take a look around, you probably will see those who are interested in topic and those who are simply excited by your presentations. Special thank to today’s attendees, without you I would have to talk to walls.

For future pay more attention on actuality and popularity of the topic. I personally going to create monkeysurvey to get that information.

With smaller audience you get more feedbacks. Why? Easily, they feel more relaxed and you have more time to allocate to each of them. In today’s presenation I got so many interesting questions and figured them out for myself and for audience online, while writing code. That was amazing.

Try to understand those who did not participate. Probably they counted to be more reasonable to spend that hour on some urgent issues or they discounted topic, since they are sure that will not need AutoMapper. And if they even will need it, it is quite possible to learn it in amount of couple of hours.

Still be proud of yourself. This is must be, otherwise you will lose confidence which costs a lot.


For my presentation I’ve used already existing posts on AutoMapper, also for the end of presentation I had real world usage examples.

Lviv .NET User Group: My presentation on NHibernate

July 15, 2010 LvivNetUserGroup, NHibernate, Presentation No comments

Hello, as many of you know yesterday I spoke to NHibernate at local .NET User Group.

I won 20 beers, because we’ve got > 30 attendees

It was group’s 4-th meeting and it went extremely well. Above 40 people participated and for me it was biggest audience I ever had to talk to during one hour or so. For another speaker – Derik Whittaker – I’m sure that this is not biggest audience he had, but maybe the biggest foreign language speaking audience. If I’m wrong please correct me.

Audience asked questions

People were asking me lot of questions and I tried to answer quickly and easily, but keeping in mind that I should continue and be in time, since it is bad practice to overtime speech.

I asked questions

To my own surprise flow of delivering this presentation was so smooth and harmonic with audience. Asking people simple questions, making them shaking their hands and keeping attention, because maybe another time I’ll ask exactly someone from them.

I’m proud for my presentation skills

From day to day I become better in my ability to talk easily to technical audience. This time I’ve got the most sophisticated audience I ever had. They all had good experience working on different projects. So it was not like talking to university guys, who are very “green” in their understanding of technology and how things should look like.

Presentation itself

You could take a look at my presentation below.

Not enough time to finish my second demo

For my second demo I allocated about 20 minutes, but it turned out, that I got about 10 and also talking to it and coding takes longer than sitting with my own keyboard and typing it at light speed. So sorry guys for not showing what I planned there.
What was planned and I did not show is: demoing lazy loading, chasing, complex Criteria API, and maybe the interesting – implementing own UnitOfWork and NHibernate repositories, approaches to build domain model with NHibernate.
BTW: I’m also going to have another blog post on NHibernate itself.

Really looking forward to get your feedback! Please leave your comments!
