Consider nixing the projector for quick demos

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/consider_nixing_the_projector_for_quick_demos.htm]

Say you want to do continuous development, with quick demos to management (or business sponsors) every week. One thing I've found useful is to nix the projector. I've been in places where in meetings, you can't show something on a computer unless it's on a projector. And of course for large meetings and official presentations I can see the benefit. However, if you want just a small and quick sanity-check meeting, there are several benefits to nix the projector:

• Faster setup - I've seen endless problems trying to hook developer machines up to a seemingly innocent projector (can't turn on the projector, need to install special sofware, your laptop won't register, the screen doesn't show, different resolution sizes, adjust the font size, bad glare from the windows, etc...). If you only want a 10-minute "spot-check" demo, you don't want to waste even 5 minutes setting up a projector.
• Smaller crowd - Something about human nature seems to be drawn to a presentation on the big screen (Maybe people think the bigger the screen, the more important, and they don't want to miss out on important things). However, by having just a laptop screen, it forces you to have a smaller crowd - maybe 5 or 6 people at the most.
• Easier for multiple machines - Switching a projector between multiple laptops can also be risky (see "faster setup"). If for some reason you have multiple laptops (say you haven't integrated all the pieces for the demo onto a single machine yet, or you're showing very different scenarios that don't "fit" on one laptop), not having to worry about switching the projector can just make it more convenient.
• Easier room requirements - A lot of offices only have a few "special" rooms that contain projectors - and these rooms are usually already booked. Not needing a projector means you aren't limited to these special rooms, and therefore have far more room options available.

I realize it's trivial in the scheme of things, but not needing to worry about the projector can eliminate some of the red tape and setup that distracts you from the things that aren't trivial.

Chicago Code Camp website is live

The LCNUG and ALT.Net groups are pleased to present the Chicago Code Camp on May 30th at College of Lake County. We've got the website up, and it will continually add more details there.

So far, we're expecting a broad range of talks from many different speakers.

As a reminder, this is a free event.

You are not alone

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/you_are_not_alone.htm]

I continually try to get more involved in the developer community (such as via user groups and tech events). This gives me the opportunity to talk to developers across a wide spectrum of different projects. One type of developer, for whom my heart really goes out to, is the lone developer struggling in isolation. They're trying, but they're on a team of one - the only consultant on a project, a remote developer working from home, or the only developer in a one-person "department" of a small company.

The problem is that software engineering is too hard to do alone. It's easy to feel like you're on the outside looking in - while other departments have niche experts and devs to cover your back, you're left all by your lonesome to figure out the entire thing yourself.

Sometimes you can get out of the situation - switch jobs or press the business sponsors to hire a secondary dev (do they really want the entire project resting with one person, without any backup if you become unavailable?)

However, even if you cannot change your department or project's headcount, you are still never alone. Especially with the online developer community, blogs, forums, user groups, conferences, books, and the like. It is one joy of software engineering in today's world - you are never alone.

How will you learn the next wave?

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/how_will_you_learn_the_next_wave.htm]

New technology is constantly coming out. Some of these are small - a new tool, a special trick, or some open source library - and these can be learned easily enough. However, every few years, there's a fundamentally new wave of technologies that makes the previous wave obsolete. For example, classic ASP to ASP.Net 1.0, to ASP.Net (3.5 with Ajax, JQuery, and MVC) to Silverlight. - every few years there's a significantly more powerful UI technology.

So, the question becomes, how do you continually keep up with the next wave?

You have three main categories of options:

• Your company trains you. This was popular during good economic times. Some companies have a training budget based on a percent of the employee's salary.
• Your company doesn't train you, so instead you train yourself.
• You don't keep up, and eventually become obsolete.

The last option speaks for itself - but there's a difficult balance between the first two. Every developer should be able to ask their manager "What role, if any, does the company have in assisting me to learn the next wave of technologies?" Every manager should have a ready answer.

Realistically, you need both internal motivation and external support. For example, if your company won't even pay for a $30 book on a hot new technology, then you're screwed. On the other hand, you simply can't learn a whole new technology by passively skimming blogs during your lunch hour.

Personally, I'd emphasize the concept of an upward spiral. If you want to be a decent developer, be prepared to invest:

• Time - prepare to spend on average of at least 8-10 hours a week doing continual education. Maybe you're working 60+ hour weeks at your company, and the 10 hours is part of that. Maybe you have a "cushy" 40-hour week job and you do the 10 hours on your "free time". Sure, there are weeks (or even entire months) where life needs you to take a break. Likewise, there will be other times when an in-demand tech first comes out that you may be sprinting.
• People - Try to get to a live-person event at least once a year, such as a user group or conference. Also, explicitly seek out peers who you can collaborate with (even doing informal code reviews with your coworkers, or discussing ideas during a lunch break).
• Blogs - Use a blog aggregator to continually monitor the industry leader's blogs. This will give you a heads up of new techs coming down the pipeline, so you can prepare. If the tech actually has potential (as opposed to just some other buzzword), you'll see it light up on multiple people's blogs.
• Books - Especially for a new wave, or for matured design patterns on existing techs, try to read a full book at least twice a year (I think once every other month is more ideal, but there's a balance).
• Projects - If you have the opportunity, put in the extra work to get on a project that uses a new technology that appeals to you. Ultimately, the best way to learn a new tech is to actually use it, and unless you use it on a real project, you'll always remain a hobbyist.

Essentially, learning a new technology takes hard, pro-active, work, which many devs are already willing to do. The question becomes how to best maximize your investment on that hard work.

Real Life: Copying code is easier than copying snow dinosaurs

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/real_life_copying_code_is_easier_than_copying_snow_dinosaur.htm]

In Chicago, we get snow at the end of March. The warmer weather makes the snow packy, so we could finally do useful things with it, like make snow dinosaurs:

 

Actually, it was just one snow dinosaur - which brings me to my point: In the physical world, it's expensive to reduplicate work. For each snowball, I need to find an open patch of snow (material) and manually roll the ball (labor). Unlike software, I cannot just create the "code" once and copy it five times. It's not like some million-line application framework that you can just reduplicate with a single copy command. Hence, after an hour of exhausting snow-ball rolling and lifting, to my son's disappointment, we stopped at just one snow-dinosaur. Now if we just made a Silverlight game with snow dinosaurs, we could add as many as we wanted.

BOOK: Making Things Happen

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/book_making_things_happen.htm]

I got to finish reading another good book: Making Things Happen: Mastering Project Management, by Scott Berkun. Scott worked for 10 years at Microsoft, which included projects on IE, MSN, and Windows. The book is practical and engaging - definitely not one of these ivory-tower things that bore you to death. All the book drawings also look like sketches on the back of a napkin - no MS Visio here.

Perhaps what I find interesting about it is that so many developers think that the only thing they really need is super technical knowledge - "If I'm just brilliant, then everyone will recognize my brilliance, and life will be good." This is simply not true - there are non-technical factors that can kill projects and careers: people skills, politics, bad management, etc... My entire software career, I've seen people significantly smarter than myself who crash and burn because, although they got the tech skills, they are clueless about how to convert those tech skills to "make things happen".

Scott divides his book into three main parts:

1. Plans
2. Skills
3. Management

Amongst those three main categories, he covers a broad spectrum of vital, yet non-technical skills, such as figuring out what to do, making good decisions, how not to annoy people, what to do when things go wrong, and actually getting things to happen.

Some quotes I liked:

• "failures force us to pay attention." (pg. 5)
• [about schedules] "attempting to predict the future - something our species rarely does well." (pg. 31)
• "The more change that is expected, the shorter the milestones should be." (pg. 39)
• "Volume should never be confused with quality. Unfortunately, because volume is easier to produce than quality..." (pg. 79)
• "innovative work often occurs when one person has both requirements and design authority" (pg. 94)
• "programmers tend not to be interested in writing things that don't compile." (pg. 140)
• "If I can't come up with more than one choice, I clearly don't understand the problem well enough: there are always alternatives." (pg. 161)
• "For most tough decisions, the problem isn't a lack of data. Tough decisions exist no matter how much information you have." (pg. 167)
• "You have to  be willing to get burned if you want to develop the skill of putting out fires." (pg. 222)
• "if you can't say no, you can't manage." (pg. 265)
• "As a rule, the further a team gets from reality, the harder it is to make good things happen." (pg. 267)

Tips to be a good code-reviewer

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/tips_to_be_a_good_codereviewer.htm]

Code reviews are essential to high-quality code. Imagine back in high school when you're taking a difficult math test, and then in the last few minutes, the teacher lets you pair up with another student to compare your answers. You almost always will catch extra errors that way, and it's the exact same result with a code review. So, given that we all know that we should do some sort of code review, here are ideas on how to be a good code reviewer:

• Always keep in mind that the other person worked hard on it, and they probably have an emotional attachment. Someone once said something like "Their code is like their baby - don't say 'he looks so ugly', rather make a nice comment like 'Oh, he looks just like his father.' "
• Start with major things first. Don't start nit-picking ("your naming convention isn't good"), if they have major other issues. Focus on their biggest need. If they want your opinion on the data access strategy, that's what they'll be most receptive too.
• Don't just be a rubber stamp - it wastes their time by giving them a false sense of security and tells them nothing new.
• Look to affirm good ideas as well as discourage bad ones.
• Unless they are really missing the basic concepts, don't just tell them to go read some 500 page book - they'll see it as you dismissing them. Give them a tangible example and perhaps provide a web link to a short article or reference guide. If they read that (or they ask for more material), then suggest the books.
• Keep the session relatively short, short enough to fit within their attention span.
• Keep in mind the goal is to make better code for the good of the team, not show off how smart you are.
