Leon Gersing, Jim Holmes, and I are putting on our Software Engineering 101 event this Saturday, Februrary 27 in Nashville. If you’re not in Nashville (and you probably aren’t), you can watch the entire event online on LiveMeeting!

We’ll cover topics like object-oriented programming, the SOLID principles, and code metrics and we’ll spend the afternoon doing some hands-on test-driven development. This event was a lot of fun the first time we did it and I’m really looking forward to it.

You can register for this FREE event here (you need to register if you want to watch online to get the LiveMeeting info).

Three years ago, my three year plan was to go off on my own as an independent consultant. Well, it’s year 3 and the time has come to make it happen.

For the past four years, I have worked at Quick Solutions and I have loved it. I came into Quick Solutions never having done ASP.NET and ended up getting all kinds of experience in all kinds of different technologies. I never could’ve learned as much as I did and I certainly would not be in this spot today if it weren’t for all of the really smart people that I got to work with.

So what am I going to be doing now? I’m still going to be leading a .NET project for Quick Solutions. There will be plenty of blogging and I have some side business ideas to work on. You will most likely see plenty of me at various community events, lunches, code and coffee, and whatever else is going on.

I don’t know what the future will hold, but I always remember the line in Good Will Hunting where Robin Williams says that he’s going to put his money on the table and see what cards he’ll get. I’m really looking forward to it.

If you’re going to CodeMash next week, I’ll be speaking at a couple of sessions. On Wednesday morning, I’ll be doing a PreCompiler session on object-oriented programming and the SOLID principles. I’m not big on 101 level talks, so this will be very little beginner material and mostly advanced OOP ninja stuff. I know this doesn’t sound very sexy, but learning advanced OOP and SOLID has drastically improved the code that I write, which is why I’m talking about it. We’ll do some hands-on coding too, so bring your laptop and get ready to learn from each other.

I’ll also be doing a short 30-minute session on how to convince others to do test-driven development. This is a touchy, difficult task that requires lots of tact, patience, and passion for TDD, but it can be done! I’m not sure what time I’ll be doing this, but check the schedule when you get there and you should find it (it will be in the vendor session timeslot).

This is your annual reminder that you need to go to CodeMash this coming January. I’ve gone the last two years and I look forward to it every year. In three days time you can get exposed to pretty much anything relating to software development, and as far as conferences go, it’s really cheap. So if you want to see why people are making such a big deal about Ruby, or you want to learn how to write iPhone apps, or if you want to learn how to do TDD, or just learn more about what you do at your day job, then CodeMash is for you!

Not only are there great sessions, there are open spaces going on throughout the whole conference. Open spaces are self-organizing discussions where you propose a topic that you want to talk about and put it on the board in a time slot. So not only will you have the great eyes-forward conference sessions, there are several open spaces in each time slot where you can go and talk with other people on whatever topics you can think up. Last year I spent almost the entire conference in the open spaces and I had a great time.

Every year people come from all over the country to come to CodeMash, and last year it sold out. It’s well on its way to selling out again, so go bug your boss as soon as you can and tell him or her that you need to go to CodeMash.

Oh, and I’ll be speaking at the PreCompiler (the first day of the event) on OOP, the SOLID principles, and other “clean code” tips! It’ll be an interactive session when we’ll do some coding and learn from each other, so it should be fun. I know I’m looking forward to it.

Hope to see you at CodeMash!

I’m always looking for ways (whether or big or small) to make the software development process faster, and here’s a real easy win — use IIS instead of Cassini. Cassini was a good idea in concept (allows you to develop web applications without IIS), but it’s also really slow. If you’ve used it, you know what I’m talking about — every time you debug your application, you have to wait 20 seconds for Cassini to start up. Fortunately there is a better way, and that way is to use IIS instead.

The first thing is that you need to be developing a web application, not a web site. I can’t think of any reason to use a web site over a web application. So I’m going to assume that you already have a web application. I’m also using IIS 7. If you’re using IIS 6, you can still do all of the same things, but you have a different IIS console. But you should still be able to figure it out.

Step 1: Create a new application pool by right-clicking on “Application Pools” in the IIS management console. I suppose you could use an existing application pool, but I always like to make a new one. This way, you don’t have one application pool being used for multiple sites, because then you can’t change the application pool settings without affecting all of those sites. After you create the new application pool, click Start in the panel on the right to start the app pool.

Step 2: Right click on “Sites” in the IIS management console and select Add New Site. The physical path should be the local path on your drive to the folder that contains the web.config file for your site. In the “Host name” text box, just make up some host name. For example, “dev.mysite.com”. It doesn’t matter what you pick, just pick a host name that doesn’t actually exist. Also, click the “Select” button at the top and select your application pool.

Step 3: Edit your “hosts” file. This file can be found at C:\Windows\System32\drivers\etc\hosts. Enter this line at the bottom of the file:

127.0.0.1 dev.mysite.com

Use the host name that you entered when you created the new web site.

Step 4: Browse to the URL that you assigned to the site. In my case, http://dev.mysite.com. Your website should come up! Win!

Debugging your site using IIS is slightly different. In Visual Studio, edit the project properties for your web site and select the Web tab. Click on the “Use Local IIS Web Server” radio button and enter your custom URL as the Project Url (e.g. http://dev.mysite.com). Notice that there is also a checkbox that says, “Apply server settings to all users”. Ideally everyone on your team will set up IIS (because this way is much faster), but if that is not the case, you will want to uncheck that checkbox.

You can also debug your site by doing Tools / Attach to Process in Visual Studio (that’s Ctrl-Alt-P) and connecting to the w3wp.exe process (aspnet_wp.exe if you’re on Windows XP). If you don’t see w3wp.exe in the list, make sure that you check the “Show processes in all sessions” checkbox in the Attach to Process dialog box.

Happy debugging!

Hey everyone in Dayton, I’ll be speaking on the SOLID principles next Wednesday (Oct. 28) at 6pm at the Dayton .NET Developers Group. Hope to see some of you there.

90+ people showed up yesterday to learn loads of good stuff about OOP, SOLID, code metrics, production debugging, and TDD. Judging from the barrage of tweets that I saw today, I’d say the event was a smashing success!! I’m glad to see that so many people found that it was worth spending their day learning about such good stuff.

Props to Jim Holmes, who came up with original idea and did most of the leg work. He won’t take the credit, but he deserves a lot of it.

If you’re looking for the slides from my SOLID talk, you can get them here. (If you’re in Dayton, you can come see me give my SOLID talk at the Dayton .NET Developers Group on October 28!)

I’ve been a big sports fan every since I was a young kid, and one thing that always amazes me is how much emotion plays a part in pretty much every sport. For example, in the NBA last year, the home team won 60.8% of the time. If a team were able to block out emotion on the road so that they played as well on the road as they do at home, that would be a huge advantage.

Emotions affect software developers too. I didn’t really think about this so much until I noticed how I was going about things on my current project.

I’m working on a project by myself for a company that has no IT department. So I have to do all of the requirements gathering, design, development, testing, and deployment. I got all of my requirements, I estimated everything out, and I have an Excel spreadsheet where I keep track of how much work I have done and how much I should have done by this point.

I feel like I check that spreadsheet every day to make sure that the number of days of work I’ve completed is higher than the “where I should be” number. Now this isn’t all bad, it’s good for me to know where I’m at and if I’m behind. But this obsession is leading to other odd behavior.

For example, I’ve had the server I’m going to deploy on for months and I keep putting off setting it up. I didn’t conciously think this, but setting up the deployment server wouldn’t make my “hours finished” number go up in my spreadsheet, even though I obviously have to set up the deployment server sometime. So because I wanted to bump up my “hours finished” number, I would do feature development.

A couple weeks ago, I had a couple features drag on several days past the estimate I had for those features, and that was a really hard week. Not because I was in real danger of getting behind, but I was week ahead of schedule in my spreadsheet before the week and I was right on schedule after the week (I didn’t get to cross anything off that week). I felt stressed out all week.

Why was I so upset? I wasn’t even behind schedule! In reality, I ran into a feature that took longer than the estimate, while earlier in the project I had features that took less than the estimate. It really shouldn’t be a big deal.

I realized that I am addict — an addict to getting things done. We all want to be able to cross a feature off the list, and we feel like we haven’t accomplished anything on the feature until we do so.

If you want to see what a developer under pressure, watch what happens when the amount of time they’ve spent on a feature exceeds the estimate. I’ve seen developers get extremely flustered in this situation. They get irritable, they worry that someone is looking down on their performance, and often they cut corners. And for what reason? Because of an estimate, just a guess of how long something is going to take!

An estimate should have no effect on how long a feature should take. If a feature is going to take 3 days to develop, it doesn’t matter if it were estimated at 1 day or 15 days, it’s going to take 3 days. Period. If you stop writing unit tests once you’re over the estimate just to get it done, you’re doing everyone on the project and yourself a disservice.

The addiction to getting things done manifests itself in other ways. I’ve seen situations where developers could’ve spent 5 minutes installing a tool or an update that would’ve saved them loads of time over the course of a project. But they feel like they’re too busy to stop for 5 minutes and install it, so they continue doing it the slow way. These are completely logical people making very illogical decisions.

Other people won’t take the time to learn a new tool or a new technique like TDD because they would have to slow down to learn it. Sometimes this is valid (we all have deadlines), but if you honestly think that something might be able to save you lots of time in the long run, isn’t it worth spending a couple days looking into it? It might work out, and it might not. But if it doesn’t work out, all you’ve lost is two days, and if it doesn’t work out, it might revolutionize the way you write software.

I guess my point is be aware of your emotions and how they affect the way that you work. Don’t let your emotions control you and cause you to make illogical decisions. And please remember, that an estimate is just that — an estimate!

We’ve all worked with people who are adverse to change. Getting people to change and helping them to change is very difficult. The challenge is to convincing people of the need to change without tearing them down.

People always have a reason for doing things the way that they do them. I personally love ASP.NET MVC and I think that it makes software development much easier and must faster. Other people are scared of MVC because they are very comfortable with WebForms. I write tests all the time, but other people have no desire to write tests. But we all have a reason (whether good or bad) that we do things the way that we do them. The challenge is finding a way to give people a reason to change.

The fact of the matter is that many people are adverse to change. This could be for several reasons.

1. They don’t know change is an option. Every year I look back at how I wrote software a year ago and there is always something that I can’t believe that I did a year ago. A year ago I thought I was a good developer. Was I a good developer a year ago? I think I was, but there is always something that you aren’t aware of that can help you. Everyone is at different stages, and not everyone is at the same place as you. This does not necessarily mean that they are stupid or ignorant or that they don’t care, maybe they just haven’t come across something yet.

2. They don’t know why they should choose change. If you’ve been doing WebForms for the last 5 years, you probably feel that you’re pretty good at it. So why should you adopt ASP.NET MVC? I mean, is ASP.NET MVC really beneficial or just another technology that you have to learn? That is a completely legitimate question to ask, and many people are asking it these days.

If you’re trying to get someone to adopt ASP.NET MVC (or any other technology that is new to someone), you need to become a salesman. You need to sell that person on why said technology or way of doing things is going to help them. “This is the right way to do it” is not going to work. That doesn’t tell them how it’s going to help them. You need to convince them that the new way will make their life easier and then show them how to do it.

3. They don’t know how to go about changing. The best example of this is teaching people how to write unit tests. First you have to write your code so that it is testable, which means that you need to understand dependency injection and some DI container like StructureMap. Then you have to learn how to use a mocking framework like Rhino Mocks. You have to learn the difference between a unit test and an integration test, and ideally you will also learn how to write tests first. Yikes, that’s a lot of stuff to learn! The only way that I learned it all was by working with other people that knew how to do it and taught me how. So your colleagues may be willing to change, but they might just need some guidance (or a lot of guidance). They also have deadlines and don’t want to risk being late because they were trying to learn something new. This is where you need to convince them that writing tests will same them time and make their life easier because they will write less bugs and it will be easier to make changes to their code.

4. They don’t want to change. Many people are adverse to change and that’s just their personality. Other people are stubborn and don’t like people telling them that they’re wrong. These people are the difficult ones to deal with. Sometimes all of your efforts with these kinds of people will not succeed, but at least you can make an effort. I think it goes back to showing people why they should change — that there is another way to do things that will make their lives better. But getting them to this point will take a lot of patience and encouragement along the way.

Most people don’t change overnight. Even if someone wants to adopt all kinds of new technologies and practices, it may take them a long time. So give them something small to change. Instead of trying to totally rewrite their entire codebase, show them how to take a feature and write tests for it. Show them how their tests give them peace of mind because they know their code is working. Now hopefully you’ve won some more trust and can move on to bigger problems.

If you’re one of the people who is nervous about change, realize that in this industry things are constantly changing. No one can keep up with it all and know everything, so we need to rely on the expertise of others and learn whatever we can from whomever we can. It may require checking your ego at the door and realizing that you may not know the best way of doing something.

Changing might be hard work. It’s much more comfortable to do something that you know well. But nothing worthwhile is ever achieved without hard work. I promise you, you will be much better off in the end and you’ll be glad that you changed.

If there’s one thing that everyone in software development can agree on, it’s that everyone has an opinion on what the best way is to do things. We have lots of books, blogs and articles touting “best practices” and telling us how to do things (and how not to do things).

Often times as a consultant, you are brought into an IT shop where the native developers aren’t using the latest and greatest technology and might not be using the so-called “best practices” that you subscribe to. Usually in these situations, the people that brought you in are bringing you in for your expertise and are expecting you to do things the right way. This can lead to the native developers feeling somewhat threatened.

Recently a friend of mine started at a new client and noticed that the developers there were do most of their data access through dynamic SQL written in their C# code. When he questioned why they did it that way, the developers got defensive, saying things like, “We’ve been doing it that way for years and it’s been working for us.”

While the “best practices” would not recommend you doing all of your data access this way, it dawned on me, this guy is exactly right. He’s been writing his dynamic SQL for years, and he’s been succeeding in delivering working software. So in his mind, he’s not doing anything wrong.

There are two ways of handling this situation. The one that many people choose it to rip on the guy for being so stupid for ever thinking of doing it that way, while saying things like, “No one does it that way anymore”. All this does is alienate the developer and turn them off from trying to learn something new.

The preferred method is to show them that there is a better way. I once asked Andy Hunt how to get people who don’t write unit tests to start writing unit tests. His answer was that I needed to show them what was in it for them. I don’t think he could’ve been more correct. No one wants to do something just because it’s a “best practice” or some smart person said you should do it that way. We’ve all worked with people or seen projects where some “smart” person made something way more complicated than it needed to be and no one else could understand what they did or how to write code using their framework. No one cares if those people used “best practices”, you just hate having to come to work and deal with the mess that they made.

So if you’re working with someone and you think that there is a better way than how they’re doing something, show them the better way. Acknowledge the fact that what they are doing is working for them (they probably wouldn’t be doing it if it wasn’t). Just don’t belittle them for doing it that way, because they may be doing the best that they can.
