Unfulfilled programmers Erich Fromm, a famous humanist, philosopher and psychologist strongly believed that people are basically good. If he was right, then either our society is a mind-breaking dystopia or we have a great misfortune of working in a field that burns people out, because many IT people I know are more like Al Bundy than anyone else. Why is being a couch potato something wrong? Happiness can be achieved in many different ways, but not by passive pleasures. One way of pursuing happiness is by self realization and while self realization can happen in any activity, it’s makes perfect sense to have it at work, where you spend one third of your life time anyway. But many developers I know, consider work as something boring at best, dreadful at worst. True, programming can be awful, when you have to dig deep into a terrible code base without any perspective for a change, but IT is vast and you can always find something interesting, and once you learn it, you will find a way to make money on it, either by changing position inside your company or changing your employer altogether. Yet most unhappy IT professionals don’t do anything to change their situation. The main reason for that is, because it requires a lot of learning, and learning at home is not the most beloved activity for a couch potato. So why are developers turning into couch potatoes in the first place? Why the last thing a typical developer will do back home is learning and polishing his skills? There are plenty of reasons for that. The three main roots of an IT couch potato First, our work is tiresome. Nearly every job offer you can find mentions “able to work under pressure” and “flexible long working hours” in the requirements. This translates directly to the “burn-out” phenomenon. Second, the technological landscape is changing overwhelming fast. Unless you work for a slowly adapting institution like a bank, your skills will be outdated in a few years time. Sure the deceased Sun, god help us, granted Java developers four years of relative stagnation, but that’s an exception and it’s going to end soon enough anyway (unless, of course, these are just convulsions before slow death of technology). You better learn and you better learn fast, or you’ll have no other option than to promote yourself into management. Third, just how long can you sit by your computer everyday? Yeah, I know, some people spend years playing WoW, Eve and alike, barely moving. I am a sinner myself, with Steam reporting over 350 hours in Modern Warfare 2, 200 hours in F.E.A.R. 2 multi, and countless months of my life wasted by Sid’s Civilization. But for not-addicted, it’s just simply stupid, not to mention unhealthy, to have your ass integrated with the chair. No matter how comfortable it may be. There is more to life than that. Case Study at my company It all started with a few SQL programmers grumbling about how they are bored to death, and how they would like to switch to OO programming. I’m not a person who waits, so next thing I did was asking our management if they could move those guys to Java/C# projects. And the management was all for it, with just one requirement: they would have to first learn our technology stack at home, not to be totally lost and unproductive. After all, the more technologies an employee know, the more valuable he is for the employer (think about switching people between projects). A few months later and nothing has changed. I’m asking sql guys how the learning is going, and I get the answer: it hasn’t started yet. Now, I know the best way to learn something is by hands-on experience at work. After all that’s why I’ve been changing my job a few times: to have a real world experience. It’s easier to learn french if you move to Paris. And learning at home is hard because of the aforementioned reasons. The very same reasons, why you get only 650 people on a free conference, like Javarsovia. So what can we do, then? How about we remove all the obstacles? How about we make learning at home fun, satisfying and profitable. How about we provide  motivation and feedback. How about we also solve the never-ending dissonance between employee’s financial and employer’s productivity expectations on the way. Sounds interesting? Let’s try, then. First: make it profitable. Up to some point, people get motivated by money. It won’t work if you are already earning enough to pay for everything you need, but in a country like Poland, to be able to build/buy yourself a house, you have to be making many times the average salary. So here, money is still a major motivator. Every year, every developer goes back to his boss and says: I want more. Guess what, your boss wants to pay you more. No kidding. After all Henry Ford’s said:

“There is one rule for industrialists and that is: make the best quality of goods possible at the lowest cost possible, paying the highest wages possible”. Highest wages. You boss really wants to pay more. But to stay in business, the company needs you to either improve the quality or productivity. Both mean more money to the business, and more money to pay you with. If you consider that, the goal of a developer who wants to learn something new (or get better at something) is on the way to make the company more profitable. After all, this is software development – you never know what technology you gonna need tomorrow. This works both for completely new stuff, and for learning something that company is already quite good at. If you know several technologies that the company is working with, you are more valuable, because you can handle more projects (you boss may think in terms of reallocating resources). After thinking about all of this I went to my bosses and asked them: will you pay more to the people who learn different technologies at home? Even when they can’t use them right now at work? Will you give a rise to those Oracle guys, if they learn Java? The answer was: definitely! They actually said that every time a developer asks for a rise, they ask him back: what have you done in the last year to improve your market value? What have you learned? Because every time an employee’s market value increases, the company’s value increases. Simply speaking: more skills means more money. Both for the developer and for the company. It’s amazing, how often people forget about it. Making it crystal clear can give you a motivational boost to do something at home and a nice perspective. You don’t have to switch your job to get a rise. You need to learn more, and they’ll happily pay you more. Second: make it easy The main question with learning is where to start from? And for software developers it’s the most important, most difficult question, because there is no way to learn everything, because spending years studying can be simply a waste of time, if the technology is dead/outdated the moment you get productive with it. What should I learn or why should I learn at all, if the risk of wasting the most precious thing in my life, my time, is so high? How do I decide what to learn. Lets make learning safe and easy. Your best bet is to start with something that has much longer life expectancy, something that will help you right away, no matter what a technology you have to work with in your next project. And something that is relatively simple to learn: agile skills. These are skills of an agile developer, well established, well recognized, and not going away any time soon, because we still do not have anything on the horizon that could surpass them. Yeah, I know, the world ‘agile’ is so popular nowadays, that even my grandma is agile, but lets go for a solid list of things agile. No bullshit theory, no marketing mumbo jumbo, give me a precise, distilled and refined list of things I should learn, things that will help me, things worth spending my time on. Here it is: The Agile Skills Project The project is all about self improvement and learning. It’s a great inventory of “ isolated, learned, practiced, and refined” agile skills, with definitions, resources, descriptions of steps to mastery and success stories. Take a look at the “Pair Programming” page, for example. All the skills are divided into different areas: Business Value, Collaboration, Confidence, Product, Self Improvement, Supportive Culture, Technical Excellence. You even get a nice mind-map with it. This is a single reference point for all those who do not know where to start or where to go next. All these skills are in high demand on the market and with a very long Time-To-Live. The best thing is though: no matter what technology you gonna work with tomorrow, you can benefit from them. I took the list from the website, tidied it up a bit, refactored it for the needs of my company, and proposed it as a Request For Comment, a wiki page, where everyone gets to discuss and shape up the idea, before we give it to the management. Soon we had a discussion. It wasn’t easy to make everyone understand the concept, but after a while people joined in, and we added some more stuff. Level up! The Agile Skills Project is more than a simple index. It tries to create a learning ecosystem, by defining quests:
“Quests” are on-the-job experiments, self-assessments, peer-reviews, course experiences or other activities intended to help a person better apply a particular agile developer skill set. It’s a bit like a Role Playing Game. You have your quests, you do them, you get experience. For experience you get more money and new toys (technologies) to play with.  It’s fun. Billions of MMORPG players cannot be wrong. But to make that happen we need something every game has: feedback. Third: give feedback OK, so we have a bit of motivation (money) and a list of goals (agile skills). Who is going to give us quests, and who is going to tell us we did a good job? How will we have our feedback? The first and most important thing, is to see the results of you actions. Otherwise you loose focus and motivation (money can only get you that far). Therefore you should create a list of quests you have done. Put it on the intranet or somewhere, where you can show it to others. It’s important, because you are going to share it with your mentor. Yes, a mentor. Choose someone from your company, someone you trust, someone you respect. It doesn’t have to be an Einstein. Meet with this person once a month, during your work-time. An hour should do. Discuss with your mentor what quests you want to accomplish this month. Could be anything, reading an IT book, learning new programming language or taking another step to master one of the agile skills from the list. Tell your mentor when you’ll be done. Meet together again next month, and either put the quest in your done-list, or mark it as ‘failed’. The role of the mentor is to listen to you, remove obstacles, help you choose a good path and give you feedback. You’ll be surprised by how much the meeting with your mentor motivates you. It works much better than money: you don’t want to fail in the eyes of the mentor, because this is the guy you respect, and you want him to respect you as well. And once you see your constant improvement by filling the list of quests done with your mentor, it gets addictive. Smells corporate? How is this any different to what you can sometimes see in a corporation, with a year long plan of tasks your boss is giving you to accomplish to get your bonus? Well, first of all, these will be your quests, chosen by you. Second, you will choose your mentor as well. Your boss usually doesn’t know a thing about what you are doing. Third, it’s all about your self-improvement, not meeting some company goals. You get better at something, the company gets better at something. After all a company is not much more than the people working at it.  Fourth, it’s a fast feedback cycle, you do not have to wait till the end of the year to get it. And finally, it may be a bit corporate, because I have never seen any small company doing anything like this. But even if it is, it still seems like worthwhile. Anything to get me out of the couch. Discuss It’s a bit too early to tell whether the idea will be successful. We have just started. Fo me it is already helpfull, because with a list of quests done I have have a feeling of progress. If you’d like to discuss this, and other ways to animate software developers to do something more, I’m leading a meeting at Agile Warsaw group about it, on the 20th of September, 19:00. Feel invited. By the way, here you have a trial of “other ways to animate” from our internal TouK Code Jam Party, we held a week ago. Doesn’t look mych corporate, does it?

33rd Degree day 1 review

33rd Degree is over. After the one last year, my expectations were very high, but Grzegorz Duda once again proved he's more than able to deliver. With up to five tracks (most of the time: four presentations + one workshop), and ~650 attendees,  there was a lot to see and a lot to do, thus everyone will probably have a little bit different story to tell. Here is mine.

Twitter: From Ruby on Rails to the JVM

Raffi Krikorian talking about Twitter and JVM
The conference started with  Raffi Krikorian from Twitter, talking about their use for JVM. Twitter was build with Ruby but with their performance management a lot of the backend was moved to Scala, Java and Closure. Raffi noted, that for Ruby programmers Scala was easier to grasp than Java, more natural, which is quite interesting considering how many PHP guys move to Ruby these days because of the same reasons. Perhaps the path of learning Jacek Laskowski once described (Java -> Groovy -> Scala/Closure) may be on par with PHP -> Ruby -> Scala. It definitely feels like Scala is the holy grail of languages these days.

Raffi also noted, that while JVM delivered speed and a concurrency model to Twitter stack, it wasn't enough, and they've build/customized their own Garbage Collector. My guess is that Scala/Closure could also be used because of a nice concurrency solutions (STM, immutables and so on).

Raffi pointed out, that with the scale of Twitter, you easily get 3 million hits per second, and that means you probably have 3 edge cases every second. I'd love to learn listen to lessons they've learned from this.

 

Complexity of Complexity


The second keynote of the first day, was Ken Sipe talking about complexity. He made a good point that there is a difference between complex and complicated, and that we often recognize things as complex only because we are less familiar with them. This goes more interesting the moment you realize that the shift in last 20 years of computer languages, from the "Less is more" paradigm (think Java, ASM) to "More is better" (Groovy/Scala/Closure), where you have more complex language, with more powerful and less verbose syntax, that is actually not more complicated, it just looks less familiar.

So while 10 years ago, I really liked Java as a general purpose language for it's small set of rules that could get you everywhere, it turned out that to do most of the real world stuff, a lot of code had to be written. The situation got better thanks to libraries/frameworks and so on, but it's just patching. New languages have a lot of stuff build into, which makes their set of rules and syntax much more complex, but once you get familiar, the real world usage is simple, faster, better, with less traps laying around, waiting for you to fall.

Ken also pointed out, that while Entity Service Bus looks really simple on diagrams, it's usually very difficult and complicated to use from the perspective of the programmer. And that's probably why it gets chosen so often - the guys selling/buying it, look no deeper than on the diagram.

 

Pointy haired bosses and pragmatic programmers: Facts and Fallacies of Software Development

Venkat Subramaniam with Dima
Dima got lucky. Or maybe not.

Venkat Subramaniam is the kind of a speaker that talk about very simple things in a way, which makes everyone either laugh or reflect. Yes, he is a showman, but hey, that's actually good, because even if you know the subject quite well, his talks are still very entertaining.
This talk was very generic (here's my thesis: the longer the title, the more generic the talk will be), interesting and fun, but at the end I'm unable to see anything new I'd have learned, apart from the distinction between Dynamic vs Static and Strong vs Weak typing, which I've seen the last year, but managed to forgot. This may be a very interesting argument for all those who are afraid of Groovy/Ruby, after bad experience with PHP or Perl.

Build Trust in Your Build to Deployment Flow!


Frederic Simon talked about DevOps and deployment, and that was a miss in my  schedule, because of two reasons. First, the talk was aimed at DevOps specifically, and while the subject is trendy lately, without big-scale problems, deployment is a process I usually set up and forget about. It just works, mostly because I only have to deal with one (current) project at a time. 
Not much love for Dart.
Second, while Frederic has a fabulous accent and a nice, loud voice, he tends to start each sentence loud and fade the sound at the end. This, together with mics failing him badly, made half of the presentation hard to grasp unless you were sitting in the first row.
I'm not saying the presentation was bad, far from it, it just clearly wasn't for me.
I've left a few minutes before the end, to see how many people came to Dart presentation by Mike West. I was kind of interested, since I'm following Warsaw Google Technology User Group and heard a few voices about why I should pay attentions to that new Google language. As you can see from the picture on the right, the majority tends to disagree with that opinion.

 

Non blocking, composable reactive web programming with Iteratees

Sadek Drobi's talk about Iteratees in Play 2.0 was very refreshing. Perhaps because I've never used Play before, but the presentation was flawless, with well explained problems, concepts and solutions.
Sadek started with a reflection on how much CPU we waste waiting for IO in web development, then moved to Play's Iteratees, to explain the concept and implementation, which while very different from the that overused Request/Servlet model, looked really nice and simple. I'm not sure though, how much the problem is present when you have a simple service, serving static content before your app server. Think apache (and faster) before tomcat. That won't fix the upload/download issue though, which is beautifully solved in Play 2.0

The Future of the Java Platform: Java SE 8 & Beyond


Simon Ritter is an intriguing fellow. If you take a glance at his work history (AT&T UNIX System Labs -> Novell -> Sun -> Oracle), you can easily see, he's a heavy weight player.
His presentation was rich in content, no corpo-bullshit. He started with a bit of history of JCP and how it looks like right now, then moved to the most interesting stuff, changes. Now I could give you a summary here, but there is really no point: you'd be much better taking look at the slides. There are only 48 of them, but everything is self-explanatory.
While I'm very disappointed with the speed of changes, especially when compared to the C# world, I'm glad with the direction and the fact that they finally want to BREAK the compatibility with the broken stuff (generics, etc.).  Moving to other languages I guess I won't be the one to scream "My god, finally!" somewhere in 2017, though. All the changes together look very promising, it's just that I'd like to have them like... now? Next year max, not near the heat death of the universe.

Simon also revealed one of the great mysteries of Java, to me:
The original idea behind JNI was to make it hard to write, to discourage people form using it.
On a side note, did you know Tegra3 has actually 5 cores? You use 4 of them, and then switch to the other one, when you battery gets low.

BOF: Spring and CloudFoundry


Having most of my folks moved to see "Typesafe stack 2.0" fabulously organized by Rafał Wasilewski and  Wojtek Erbetowski (with both of whom I had a pleasure to travel to the conference) and knowing it will be recorded, I've decided to see what Josh Long has to say about CloudFoundry, a subject I find very intriguing after the de facto fiasco of Google App Engine.

The audience was small but vibrant, mostly users of Amazon EC2, and while it turned out that Josh didn't have much, with pricing and details not yet public, the fact that Spring Source has already created their own competition (Could Foundry is both an Open Source app and a service), takes a lot from my anxiety.

For the review of the second day of the conference, go here.
