Today I performed meeting on WCF. It was continuation of this thread of meetings.
Couple of interesting facts about this presentation:
1) I started preparing at 3AM and continued doing this till actual presentation at 1 PM. (Yeah I of course responded to some of e-mails at work and did some other stuff, but anyway most time spent on preparation)
2) Also I want to my English teacher to forgive my absence on today’s English Lesson. Additional 1,5 hour really helped me. Guys, could you please ensure her that presentation cost all the money?
3) I took to much stuff to talk during 1 hour. Initially I prepared following list:
So I crossed some items, but it turned about that we had time only for two first items in bold.
Regardless of that many people, I’m sure, liked it very much.
4) I did a lot of coding during presentation, I hope guys liked this. Right?
5) I was forgetting about zooming and colors on projector. My bad.
6) There was not enough sit places for guys, many of them simply stand near the wall. Sorry for that. I hope managers will resolve this issue soon. He-he.
7) I kept them all interested in further presentation, since Security was not mentioned at all :-P
8) Main Links from this presentation:
9) You can go and download my presentation (I removed transactions to have something to show next time) using this link.
10) So mainly I talked on Sessions and Instances.
11) But, then I also talked on items listed below:
12) Thank you!
Guys, I will appreciate your comments/suggestions/thoughts here!
I had chance to speak at yet another Lviv .NET UG meeting. This time I spoke about Domain-Driven Design. It looks like people got interested in this topic.
You can read my feedback post about this event at Lviv .NET UG site by the link “Зустріч #7. Враження, враження, враження…” (it is in Ukrainian).
I will write almost the same here and add some own opinions, so it would be interested not only for those who doesn’t know Ukrainian, but for those who would like to hear my personal opinions.
How it was
It was really great that we’ve got more than 80 people registered for this event. And if company where we hosted this event would provide us with bigger meeting room, we would probably have over 50 near 60 people attending. So as you understand because there was lack of physical room some people just turned around and went home. Crap! I would love to have them all listening to me.
Event has two speakers, me and Igor Racyborynsky. Ihor talked about “Getting Scrum”. We all played scrum and formed following product backlog:
It was really interesting, at least not as usual presentation. But he has not covered all about the scrum and at least key concepts. Although it went extremely good.
I talked about Domain-Driven Design for the 5th time. Yeah! I even don’t need any time to get prepared.
It was late in the evening, so many people got tired, especially me talking over 1 hour bombarding with new and new terms and mentioning lot of information about known concepts and patterns.
This time I’ve got many different cool presents:
Do you know what I like about delivering presentation to huge audience? – I always get couple of people that are excited about my speech and interested in my. They then come and talk with me as I’m an expert. I feet bit scary and nervous to show that I’m not that cool :)
As usual we have small beer party in the end. This time it probably wasn’t that small. You decide:
Speaking at JUG about DDD
Today I was invited to Java User Group meeting to talk about DDD again. Thank you guys.
Tuesday, Presentation for Main Office
Whole night before presentation I spent reading some awesome articles on DDD and really enjoyed it. That leaded to 4 hours of sleep. Also I took some anti-cold medicine with paracetamol, like on the picture below:
Rule of the presenter, you probably have never heard about:
Feedback that I got from this office is like 4.5 out of 5, in details my knowledge of topic and presenting was ok, but something was not really up to their expectations.
Wednesday, Presentation for Dev Centers
Did not get official feedback from them. None voted :(
Thursday, Presentation for Lviv2 Office
So the whole conference was divided into many sections in which of them Speakers, like me, talked on different stuff. Sections were: (.NET), (Databases, Management), (Mobile, WEB), (PHP, QA) and they were located on 3rd floor (see picture below).
Except of the regular speeches in Open Space sections, there was a huge showroom, were Guru, as they call them, were talking:
As I read from other blog posts this year it was first year, when IT-Jam had separate section for .NET and I should be proved that I took part in it.
So the agenda for .NET section:
Since I was speaker I did not leave my .NET section till my delivery, so I listened to Viacheslav and Dima. Both presented very well. Dima made the whole public laughing by using jokes with mentioning Kharkiv’s governor and organizers of the IT-Jam.
My time. I plugged in proector and it turned out, that my resolution has significantly decreased. Was needed to move to “Full Screen” mode in VS and making sure that other tools I’m using fit well. My presentation was more about writing code then about showing slides and talking around them.
Here is presentation itself:
In first demo I wrote ever simplest console application, you probably saw in many introduction videos on MEF.
Second demo was dedicated to demonstrate features of the MEF, like Laziness, Recomposition, Metadata. So I built simple WPF (maybe my second WPF app, after VS plugin) and plugin functionality. Each plugin was able to provide simple string. Here I mentioned one of the teachers on first courses in Lviv University. She used to write “Hellow Word!” :) on the board. So I was needed to implement new version of plugin (Metadata) and reload it (with Recomposition, for example). Guys, who studied there do you remember?
In the end I got many-many questions. It was just question-storm. Wow! I really liked it. Just presenting is very simple, but being able to answer for all questions is something where you should be additional prepared.
Parts Lifetime Question
There was one question where I answered not completely correctly. Question was: “Does CompositionContainer keep references to the parts it clued together.” I answered that yes. But correct answer is not that trivial. MEF is smart enough to keep references only to things that are shared and do not implement IDisposable. You can read in details here. I hope that guy will take a look at my blog and will get correct answer. I really worry about my reputation as public speaker.
As I counted up to 70 people were listening to me and this is the biggest audience I ever had. Hope that number of readers of my blog will increase. Cannot check it right now, since I’m now in train and out of any acceptable connection.
THANK YOU ALL!
Thanks to organizers everything was on the top of people expectations. They managed to host 1200 attendees and make everyone happy. Plus to organizing conference they prepared free food everywhere and party for the evening. They made IT-Jam awesome kick-ass cool event!
Next day I had great time in Kharkiv, I will probably put link [here] to the blog post of my girlfriend very soon. Really enjoyed its monuments (except of “red star” kind), a lot of fountains, great zoo, cable way and other see-sights.
