Software Craftsmanship at CodeMash Wednesday

If you’re attending CodeMash 2015, you should join me on Wednesday for my precompiler workshop (even if you attended my workshop last year). We’ll be spending the whole day improving our skills, learning about software craftsmanship, and pairing up on programming exercises designed to help you improve the way you learn and practice your coding skills.

If you’ve never attended a software craftsmanship event before, you really should. The entire goal is making sure that you have fun and are able to continue learning more after you leave the event.

For those lucky few of you staying in the Kalahari (still unlikely, since you would have to bribe someone to have even gotten one), I’ve included a set of directions for how to get straight to the Software Craftsmanship Precompiler.


If you eat breakfast in the dining hall before the workshop, we’re just outside of there.

What to Bring

Bring a laptop if you have one.

Try to have an IDE to write some code in. Choose a language you’re familiar with or want to become more familiar with. It doesn’t matter!

Make sure that you have a testing framework and test runner of some kind. As long as you can write unit tests with it, you’re good.

If you’re not sure how to get these things set up, show up early and talk with us. We’ll help if we have the time and correct expertise or we’ll find someone who does!

July HudsonSC

The Hudson Software Craftsmanship Group will be meeting July 20, 2011 at 6:00 p.m. with people arriving as early as 5:30. As usual, we will be ordering pizza, and some of us will be gathering at Kepner’s Tavern after the event to continue our discussions.

If you haven’t attended HudsonSC yet, I highly recommend the group. We have a fantastic group of software craftsmen who are always trying to improve their skills as developers. If you’re interested, please sign up to let us know you’re attending. We will also not turn people away at the door, so feel free to just show up for the event.

The event is located in downtown Hudson at 102 First Street. When you enter the building, just go to the second floor and turn right. Keep walking straight, and you will arrive in our meeting room.

This month I am going to suggest to the group that we try an AppKata instead of our usual programming exercises. These focus more on real-world scenarios and include changing requirements.

We are very loose with our agenda, so if you want to bring in something to talk about or an activity to do, go for it. In fact, you can show up and suggest topics and ideas for that day’s meeting.

See you there!

One Year of Hudson Software Craftsmanship

HudsonSC Over a year ago, Steve Smith, Rich Henning, and I met to plan our first meeting of the Hudson Software Craftsmanship group. We decided on a format for the group, planned how we were going to organize the events, and came up with some topics to discuss for our first meeting since we didn’t expect people to arrive for the first meeting with lightning talks and discussion topics prepared. We also came up with the time for the meeting which would be the third Wednesday of each month, and we set up the first meeting of the group.

Since that point we have been very impressed with the core group of members who have stepped up to take part in the group and really help improve their own and others’ craft. We put on a local Software Engineering 101 event in Cleveland where four HudsonSC members, @ardalis, @brendoneus, @kevinkuebler, and @ropog, took the time to discuss some topics and run the group in exercising their skills. The class was a great success and I, as a member of HudsonSC was proud to be a part of it.

The group is always looking for new members, so if you’re in the Northeast Ohio area, please drive to Hudson, Ohio once a month on the third Wednesday of the month. We prefer if you sign up, but you can just show up and we will not turn you away. Everyone is welcome.

Sign up for the August 2010 event now!

Look for more information on the group on the Hudson Software Craftsmanship site.

Fresh opinions, ideas, and technology are always welcome.

Thank you for a great year, HudsonSC!

Software Engineering 101 Cleveland Slides and Demos

Our Cleveland-based Software Engineering 101 event was modeled after two previous, successful events in Columbus and Nashville. The event was held at the Microsoft office in Independence, Ohio. The event went over very well; we managed to get a great group of about 50 students out for the event. Our negative feedback was the lack of Internet access and the fire alarm, which interrupted the event. Our schedule was thrown off a bit by the fire alarm, and we only needed to leave for lunch slightly early as a result. Other than that things went off without a hitch.

These are my slides on Object Oriented Principles, Practices, and Patterns. The practices of object oriented development I covered tie the principles together, and the patterns, strategy and template method, tie the principles together as well as prepare for Steve’s talk which followed mine.

These are my demos on Object Oriented Principles and Patterns. They’re simple and show the basic concepts of the slides.

Before throwing people into the deep with testing, I did a quick 15 minute introduction to testing.

Our hands-on programming exercise also went very well. I think we challenged some attendees and gave others some due practice by following previous examples and using the Greed Kata. This problem was great for reinforcing the concepts of my first talk, and if someone tried to follow the Open/Closed Principle while doing the problem they likely used the strategy pattern. I’d love for people to send me their implementations of the Greed Kata, so lets see what you’ve got.

Overall the event went well. Perhaps there is another one in our future. Let us know if you’d like us to do another.

We of course could not have done the event without the help of our organizing sponsors: Hudson Software Craftsmanship, NimblePros, and Microsoft. We are also grateful to our prize sponsors who offered up great prizes for the attendees: Pluralsight, DevExpress, NimblePros, JetBrains, and PreEmptive Solutions.

Software Engineering 101 in Cleveland

This week I’ll be speaking at a free day-long event for developers to improve their software engineering skills. The event is being held at the Microsoft office in Independence, Ohio. Microsoft is hosting the event being organized by the Hudson Software Craftsmanship group and NimblePros consulting services.

I’ll be kicking off the event with my main topic: Principles of Object Oriented Programming. Other topics will include: SOLID Software Development, Software Testing, and Specification Driven Testing. In the afternoon we’ll be doing Hands-On Exercises.

There are only a dozen seats remaining for the event scheduled for July 16, 2010. We’ll be starting in the morning at 8:30 AM and running until 4:00 PM. We’re looking forward to seeing you there!

Registration for the event is free and easy. Sign up now for the Software Engineering 101 – Cleveland event. Seats are limited, so register soon.

HudsonSC January 2010 Recap

Last night we had a great HudsonSC meeting. People started showing up around 5:30, and I had the opportunity to meet and talk with a few new attendees during that time.

Lightning Talks

At around 6:00 we got things started. Kevin Kuebler started us off with an interesting talk on BDD where he showed some interesting code using MSpec. As usual, he was unable to keep his talk under 10 minutes. We will not fault him for that though, since he discussed the topic well and showed some cool code.

Following Kevin’s talk, we had a well-timed talked from Yasir Drabu about the Unit of Work pattern, which I in no way pressured him into giving at the last minute. Yasir let us know that he was currently implementing this, and he would show us the eventual implementation at a later meeting.

Open Spaces

Our open space discussions start at the same time pizza arrives, so people can sit around eating pizza and discussing interesting topics. The selected topics of the evening were “How to promote agile practices at your workplace” and “Automated build processes”.

I’ll defer to someone else about how the agile practices open space went, but I do believe the build processes discussion was interesting. Continuous integration, build automation scripts, and database change management were the hot topics of discussion among that group.

Coding Exercises

As usual we finished up the meeting with some time spent pair programming through some coding exercises. This time we took our second group attempt through our customized version of KataPotter.

We had a few interesting solutions to the exercise, and each one handled the optimization for getting the price down differently. They all seem to work effectively according to the unit tests. I know my solution was very different from the previous one I used to solve this exercise.

In Northeast Ohio? Come to HudsonSC the third Wednesday of each month in Hudson, Ohio.

My First CodeMash

As a late adopter of CodeMash I can say that version was a great event. There were hundreds of developers there ready to learn and try new things. The intelligent, interesting people sparked many worthwhile conversations. If you’re in the area around Sandusky, Ohio, I highly recommend that you attend the next CodeMash.

Not Your Everyday Conference

I was very pleased with how things were handled with CodeMash. It didn’t feel like the standard “sit in your seat while someone talks at you for an hour”. I really think that involving people is the best way to spread knowledge. One of my favorite quotes touches on this perfectly.

Tell me and I forget. Teach me and I remember. Involve me and I learn.

I can’t say what it was like at every session at CodeMash, but the sessions I attended tried to include the audience when possible.

Software Craftsmanship Workshop

CodeMash has a precompiler the day before the event. The precompiler is a day with two time slots of four hours each. Steve Smith and I ran a workshop during that timeslot. Our Software Craftsmanship workshop went very well. We started by introducing everyone to the concept of Software Craftsmanship. At the end of the day I like to boil this down to people caring about writing good, clean software.

So how does one get better at writing good, clean software? Practice.

  • Write something small and write it well.
  • Try new approaches to a known problem to see if you can improve upon it.
  • Follow along with a known good solution and understand how someone else solves things.
  • Take some bad code and refactor it again and again.

In case you haven’t guessed the goal of our workshop was to give people some practice as well as show them how they can practice on their own in the future.

We started with the Bowling Game Kata from Uncle Bob Martin.  First we went through the slides discussing at each step what he was doing and why he was doing it. This is a great exercise because it lets you see what Uncle Bob does when he hits a wall and needs to back up. At one point in the Kata he realizes that the path he is going down is not correct. This shows you how to identify this situation and then how to resolve it.

After this quick introduction we had everyone dive in with their favorite language attempting to calculate the score of a bowling game.

We continued on with some other exercises including: discussion of followed by implementation of a Supermarket Pricing system and we ended with a bit of fun with FizzBuzz.

I hope those who attended enjoyed the experience, and I welcome everyone to come by our Hudson Software Craftsmanship meetings which meet on the third Wednesday of the month in Hudson , Ohio.

Coding Dojo

This year CodeMash also had a Coding Dojo dedicated to these exercises. Instructions were provided explaining the requirements of the exercises. Some are katas like the bowling game and others exercises to challenge you with creating a good, clean solution to a relatively simple problem.

We recommended people work in pairs with someone they didn’t know, but we had a few people working solo.

Sara Ford stopped by the coding dojo and it seems had a beef with my overuse of the word “kata”. If you’re interested, Steve Smith wrote an interesting response discussing coding katas. The bowling game is a kata to be followed along with and matched exactly. The more closely and exactly that one can match how UncleBob does the kata the better. Some of the other challenges presented there I probably should have titled as “exercises”. Next year, I’ll make sure to have more time to prepare the coding dojo. I hope to see you there.

CodeMash 2010 is this week

logo-codemash I will be attending a great regional event this week. The event is called CodeMash and it is located in Sandusky, Ohio. As the CodeMash site describes it.

CodeMash is a unique event that will educate developers on current practices, methodologies, and technology trends in a variety of platforms and development languages such as Java, .Net, Ruby, Python and PHP.

I hope everyone attending has a safe trip there and has a good time. I look forward to seeing you there. You’ll find me at the Precompiler Software Craftsmanship workshop as well as at the Coding Dojo, which will be open Thursday and Friday in the Banyan room.

I look forward to seeing you all there. If you don’t make it out this year, there is always next year. Have a great week everyone!

Party with Palermo

If you've ever gone to a conference and not known what to do on the first night, you should check out Party with Palermo. Hosted by Jeffrey Palermo, these parties are a good time. Free finger food, free swag, and free drink. The next one is for Alt.Net and the MVP Summit. On the first day of March 2009 from 7:00 PM until 10:00 PM the party will be at Jillian's 731 Westlake Ave N, Seattle, WA 98109.

The event is fun and easy to attend. Palermo wants people to RSVP on his site. Even if you don't respond, you can still show up. The price of admission is one business card. It is easy and will give you a fun event to attend.

If you are not going to be there at that time, don't worry there will be other parties with Palermo later.
