So You Think You Want To Write Code?

Intro

I had the opportunity to present a couple of sessions at the inaugural Dev Fest Fam conference today.

I’ll predict your next question: “Is this what has been keeping you from posting  the sequel to 2014 Developer Learning Guide Part 1?” The honest answer is no. I’ve been busy, it’s true, but I want the next installment of this post to be very good so I’ve been particular about publishing it until it is 100% ready.

#DevFestFam

This conference is a fantastic idea! It was put on by a couple of local Google User Groups and hosted at Utah Valley University. For a first time conference, it was great and I have the feeling it will only get better. The beauty of it, was that coders/programmers/developers/engineers were to bring not only their spouse or significant other, but also their kids.

I took 3 of my own and they LOVED IT. My 10-year-old daughter coded all night long until it was time for her to go to bed after we came home! So cool!

My first session, “So You Think You Want To Write Code?” was a big hit and well attended:

session attendance
Almost a full house!

 

The second was at the end of the day and was titled: “Websites for Smarties”. It was a beginners hands-on-session teaching the basics of HTML. I used w3schools and Google Sites  as resources for teaching. I won’t post more on that here.

Interview/Hire Great Devs: Part 1

Hiring great technical people starts and ends with making a great impression on the best people. This means you have to get the best people in the door.  Once you have hired some of “the best”, your team will attract more of the same but starting out can be difficult. This post focuses on what to do once you’ve attracted their initial interest. I’m specifically covering interviewing and hiring awesome developers, but much of this is applicable across technical disciplines and other skilled positions.

Initial Phase: Resume/Profile Screening

Know What You Are Looking For

NYSpyglassStart the process by knowing what kind of great technical people you are looking for. Are you looking for great young talent that is unafraid of making mistakes? Or tried and tested people who account for exceptions before they arise? Are you looking for teachers or learners (or both)? Do they need certain specific skills or only the great desire and ability to learn, grow, and improve? What is the near, mid, and long term composition of your team?

Many questions should be asked and those questions don’t always have a clear answer. Do you need a consultant or full-time hire to help determine what you are looking for?

Be able to narrow your search quickly based on your must-have criteria and let the rest be discussion points during later phases of the hiring process. Don’t spend more than 5 minutes per resume, LinkedIn profile, or StackOverflow Careers profile weeding out the “No Call” people. It should be obvious because you already know what you are looking for.

I recommend creating two Top 5 lists to assist with knowing what you are looking for. The number of items on the list isn’t the focus. Use 3 or 7 or whatever suits you. It’s the exercise that is important. Write down 5 must-have attributes and 5 must-not-have attributes. Use these lists during initial screening. Pass on anyone with less than 4 must haves or more that 1 must-not-have.

Second Phase: Phone/Online

Personality First

Phone screen or Skype/Hangout for personality and team fit first. I prefer to see people face to face but this isn’t always possible. If you are starting a new team, this phase is even more important. The person you are screening should be someone you can see yourself having an interesting conversation with over lunch. You will be spending a lot of time together building a team. Getting along well is vitally important.

Split PersonalityThe personality screen doesn’t need to be long. Maybe 15-30 minutes. If it goes well, move on to the next phase without hesitation. If is doesn’t, this is the end of the road for this candidate regardless of their other credentials. This may seem extreme or harsh but honestly it saves your time and effort as well as the candidate’s.

On the flip side of this is the importance of representing the culture and personality of your group as accurately as possible. Talk about your goals and aspirations as a team and as a company. This gives the candidate an opportunity to self-select out of the hiring process as well. You don’t want to hire people who won’t be happy in your environment. Honesty is definitely the best policy.

If you are looking for a leader (or emerging leader) this is also the time to make a early assessment of the candidate’s ability to fill this role. Confidence and charisma matter more here that they might otherwise.

The Learning/Knowing Equation

A technical (and partly cultural) phone/online screen of the people you think might be a good personality fit is the logical next step. The interview should be performed by a trusted technical member of your team. This phase is going to go back to the first section because you must know what you are looking for. Rank candidates based on that knowledge.

That said, don’t hold out for a “unicorn”. For our purposes, a unicorn is a developer who knows your tech stack inside-out, knows your business, and knows what you need to do to solve all your current and future problems. I believe unicorns can be developed if you hire people with the right potential, but they cannot be found and hired. At some point the mask comes off.

With this in mind, your focus should be on the candidate’s ability to learn and on gauging what they already know and their ability to teach it. These traits are and probably always will be vital for a technology employee. Of course you’d like someone with experience in some of your technology. The point here is not to miss out on someone who is a fantastic learner/teacher and doesn’t check all of the other boxes on your checklist.

teaching LearningI describe this second screening as partly cultural for a reason. Your interviewer should be verifying that the candidate not only can learn and adapt quickly, but also if they enjoy learning and adapting quickly. When going through the things they do know, the interviewer should look for something they are personally less familiar with. They then can encourage the candidate to teach it to them.  Remember to discover if the candidate is not only capable of teaching but also if they enjoy it. The collaboration component is important.

There are great tools to help with this phase. A good screen-sharing app like GoToMeeting, Skype, or Screen Hero is the best way to do some quick pairing on a simple problem. The problem should be something the candidate may not be wholly familiar with so that their capability of dealing with the unknown can be assessed. That said, this should still be fairly short and sweet. 30-45 minutes tops.

If it seems like this is a good possible fit, personally invite the candidate to visit your facility. If you don’t have a facility, invite them to lunch. If you are looking at remote or relocation hires and the position is permanent, you should arrange transportation/lodging. Under no circumstances should you ever make an offer at this point in the process.

The candidate should have a clear and concise understanding of the next steps at this point. If you are unsure if you should move on to in-person contact, the answer is no.

Part 2 Coming Soon

I will cover the particulars of the types of things you should be doing to “Hire Awesome” in the in person interviews. No specific date, but stay tuned. In the meantime, I’d love to see your thoughts and comments here or on Twitter.

2014 Developer Learning Guide: Part 1

Background

This is part 1 of a now complete series of blog posts. Be sure to read 2014 Developer Learning Guide Part 2 and Part 3.

I originally wrote on the subject of developer training in 2010. It was with the idea that I would convince management of the importance of training technical employees. I wrote an internal document for my boss and we implemented a couple of the ideas. My boss was understanding although his boss was less so and that limited some of our options. One year (and one move to Texas) later and I was back in the same boat; I was handing a document off to my boss and trying to convince him of its validity and importance. We eventually started some great traditions at that company and I ended up publishing my Guide To Developer Training For Managers on my blog around the same time. As I started looking into moving back to Utah in late 2012, I was despairing that I would forever have to sell leadership on the value of developer training every time I came to a new company… can you say facepalm?

facepalm

It occurred to me that I might be taking the wrong approach. As I ramped-up  on interviews I noticed that a couple of companies stood out because they already had begun to establish a culture of learning. I’m happy to say that I chose one of those companies and today I enjoy a work environment where leadership not only “gets it” but is an active promoter of learning and training. Ideas that are brought up to improve training are not only appreciated but are also seriously considered. And I don’t even have to write a long and windy proposal first.

What a difference!

I’m still going to talk briefly about a few of the reasons developer and technology employee learning is important. Convincing managers will no longer be the major focus of the article. As you may have noted from the updated title, I’m refocusing to list learning options that are possible, valuable, and current. I’ll also post an updated list each year.

Importance

The anecdote I’ve heard several time goes like this:

Decision Maker 1: What will happen to our company if we train our technology employees and they leave to find better jobs elsewhere?
Decision Maker 2: What will happen to our company if we do not train our technology employees and they stay?

Two varying points of view obviously.

On a team where learning is not important, developers tend to stagnate or move on. Will the best talent stay in an environment like this? I’ll spare you the A, B, and C-Player talk. It should be sufficient to say that a lack of learning isn’t healthy for development culture.

Ultimately, it is the responsibility of the developer to seek learning and the best developers know this. Are the best developers going to be working for companies without a great learning culture? That scenario seems unlikely to me.

Learning Options

What if I told you that a classroom isn't always the best learning environment?
Developer training doesn’t necessarily begin or end in the classroom.

There is a wide spectrum of cost among differing methods of learning. A good mix assures plenty of coverage without completely breaking the bank.

This list is meant to be only as inclusive as I could make it given my current knowledge. Please leave a comment or contact me if you know of options I’ve missed.

Online/Print

Videos

This is usually one of the best places to look for technology-specific and implementation-specific training. There are multiple options and they are growing all the time.

Free – YouTube, Vimeo, Egghead.io, Channel9, etc.
The quality of free videos varies. The only advice I can give, is to avoid wasting time with something that doesn’t seem valuable pretty quickly.

Subscription – Pluralsight, Wintellect Now, Lynda.com
Subscription-based video training tends to be pretty well curated by the company selling the subscriptions. They rely on ongoing subscriptions for revenue so new high quality content is constantly being released (or the model is not successful). Pluralsight (http://pluralsite.com/) in particular has an enormous and constantly updated library… and no, we aren’t affiliated. Pluralsight has purchased several of the smaller players to help build out their library over the past couple of years. Subscription may cost as much as $499 per year, and is a good return on investment if you learn well this way.

Purchase – Udemy, Cleancoders.com, etc.
These tend to also be of higher quality than the free options in my experience. There are some great sources out there… but you may have to hunt for them. Word of mouth has been valuable to me here.

Social Media/Blogs/Podcasts

If you enjoy this blog, follow me on Twitter.
If you enjoy the blog, follow @dubmun on Twitter.

There are a wide variety of options here. Find people who talk about things you are interested in and subscribe to their blogs or follow them on Twitter/Google+. In my experience, many of the thought leaders in the developer community are on Twitter. This has the added benefit of allowing interactions if you have a question about someone’s latest tweet or blog post.

Podcasts can also be very, very good as long as they aren’t too sales/technology focused. Choose wisely. I find them particularly useful for long commutes. HerdingCode (http://herdingcode.com/), Ruby Rogues (http://rubyrogues.com/), and Writing Excuses (my SF/Fantasy writing guilty pleasure) are among my personal favorites. A good podcast app is a must as well… downloading all the episodes manually can get tedious.

This is where the cutting edge lives and breathes. If you want to know what is really happening you should be reading and hopefully contributing to this kind of content.

Open Source Repositories

This is the section for Github, Codeplex, Google Code, and Sourceforge. Github is definitely the current leader and you can find awesome and interesting code in any of these repositories.

Looking at how other people code is a great resource for learning. Additionally, submitting a pull request to an open source project can be the fast track to learning (albeit a potentially humbling one). Humility is a good thing, it lets us know where we can improve.

Books

I’ve heard a lot of varying opinions on books as a training resource. Yes, technology-specific books are often outdated before they are printed. I generally avoid the latest C#, Java, Clojure, Javascript, etc. books (with a few exceptions). The flip side of this is… if you do choose to read tech-specific books, be sure to get the latest version.

What a library!
Some options here…

My thought is that when you are really looking to deepen your knowledge on something specific, books are a great resource.

There are also many classics that are as close to timeless as you can get in this industry. I highly recommend books like The Pragmatic Programmer, Clean Code, The Art of Unit Testing, Design Patterns, and Domain Driven Design as examples of excellent resources for learning practices and patterns or as reference material.

Books are available in several formats as well: hard-copy, ebook, and subscription.

Hard-copy and ebooks are basically just a matter of preference. I find that I like having a hard copy of books I might lend to others, but nothing beats the convenience of an ebook that you can read on multiple devices. When I have the option, I get both.

Subscription to a service that provides ebooks can be really handy as well. Particularly if you find yourself reading a lot of technology-specific books. Safari Books (http://www.safaribooksonline.com) offers hundreds of titles on technical subjects for $199 or $460 annually.

Legacy Dependency Killer

As promised, here are the slides for my hands-on coding session at Utah Code Camp. Thanks to everyone who attended the session. I had a lot of fun and I hope you did as well.

Also, the code is on Github: https://github.com/KatasForLegacyCode

I’d love to get it translated into Java, C++, and any other language that would be reasonable. I could probably do either of those myself, given past experience, but it’s been so long I couldn’t guarantee that the code I produced wasn’t legacy as well. If anyone is interested in helping out here I’d be very appreciative.

Hopefully, I’ll be creating other katas for legacy code in C# using other common patterns and publishing them here as well.

I Like Food

Hopefully this article isn’t as banal as the title suggests. “I like food” is what I say when someone in the office asks me to join them for lunch (usually).

Why?

food-question-mark-628x363

 

Because I like my teammates? Sure.

Because I’m hungry? Usually.

Because I like food? Also true.

Because want to enhance my relationship with my coworkers and build camaraderie among the group? Getting warmer but not quite. The familiarity that comes from knowing someone outside of work does tend to humanize them and help with relationships and camaraderie (and all those touchy-feely things we engineers aren’t supposed to care about because we’rerobotswhoonlyknowhowtowritecodeanddrinkmountaindewandurinateinemptybiggulps).

In my experience, the real benefit is in improvements to communication and cohesiveness. It’s in the ability we gain to understand each other as people, to know our strengths and weaknesses, to use shorthand in communication, to avoid causing or taking offense, and to just be more effective working together. Whenever possible, I like to participate in non-work activities with my brothers-and-sisters-in-code (and sometimes with others at the company as well) because it makes us more effective. Good companies/managers understand this concept and go out of their way to engage teams in “teambuilding”. This can be a dirty word in the wrong environment. Don’t work in that environment!

So unless I have an important errand to run or previous plans, invite me to lunch. I like food.
