Drive by Dank Pink

June 6, 2011 / / 2 Comments

I finally picked up a copy of Drive to read. The book looked ominously big, however I found out the two hundred (ish) pages had been printed on fairly thick paper and was pretty engaging to read overall. Pink focuses on a topic close to my heart, describing the way that people find engagement and what drives people. It’s quite relevant to the way that I like to work, and what the company I work for strives to achieve.

Pink covers a lot of interesting material, including many references and backed up by a lot of research. In it, he compares classic management techniques (financial incentives) and details research that describes why they fail to achieve what they need to do. He talks about interesting research that shows that a small financial incentive helps boost short term performance (in work that requires no thinking) at the cost of long term performance and detriment to creativity. For today’s information worker, and the chaordic environments we work in, this should really be raising alarm bells. To me, it’s akin to the systems thinkers that know that measuring and rewarding workers on the wrong incentives causes lots of problems. It also rings anecdotally to what I’ve seen some really talented people who work in these financial institutions driven into strange behaviours due to “bonus schemes” and loops.

Pink reiterates over points such as once we hit a certain wealth, happiness is no longer correlated with wealth. We seek, instead greater things. He gives many examples about how money isn’t a motivator for many people citing the achievements of Wikipedia, open source communities that build software such as Firefox and many more. He talks about once this is achieved, people are driven to solve problems, and be creative. He gives examples where people are driven to complete puzzles and games, not because they are paid to do it, because of some intrinsic drive.

Pink continually describes what gap there is between research and business and provides a way forward describing a number of elements necessary to satisfy this intrinsic drive. He talks about the need for autonomy, the idea of achieving mastery, and developing a true sense of purpose as well as providing a toolkit for people and managers to achieve this. I like to think that the agile values help businesses to focus on creating environments that help satisfy this new style of management. The idea of Software Craftsmanship emphasising lifelong learning and mastery, a common theme in agile teams to be autonomous in task completion and done right with lean thinking, building the right thing for a good purpose.

We’re not trying to be rude, honest!

May 29, 2011 / / 4 Comments

I got included in on a twitter conversation by Mark responding to Brian talking about how ThoughtWorks people at a particular conference huddled around together. It’s not the first time people have observed that. A natural reaction by people outside of that circle is to comment on this, such as, “You’re not very inclusive,” or “Crowding around together is so rude.” Having been part of these circles before, and being told this judgement (with accompanying observation), I can tell you where it stems from.

ThoughtWorks is a distributed company
Though I can only observe consultants I interact with from other companies, I feel ours is definitely very global. We encourage people to travel from one country to another, frequently rotating projects and encourage each other to present at conferences. Being located pretty much all around the world, it’s natural you don’t get to meet everyone face to face. Even here in London, I am now used to turning up for a new office event only to meet several new people. We work on different projects, so it’s natural not to meet anyone.

Our electronic-social ties are extremely strong
Internally we have, at least what I like to think of as a very active mailing list. When I post something on there, I generally get some pretty good responses particularly from the largest community of software developers. Over time, you get to know someone’s online persona. You have a picture of them in your head, and start to see the nuances of how they express themselves. Even things like twitter help to do this. It’s not uncommon for me to feel more strongly attached to people actively participating in email conversations than some people in the same office of who I rarely see or talk to.

Conferences are attended by ThoughtWorkers from around the world
As I briefly touched upon before, as a global company we try to encourage people to travel and present at conferences. This naturally leads to opportunities for people to meet in person for the first time. It’s strange meeting people you feel like you’ve known for a long time in person for the first time. I still remember, for example, my first day in the London office where I finally met Liz Keogh and Tim Emiola for the first time after conversing with them electronically for 18 months before hand, and them now inducting me into the whole Britishness of “buying rounds” and the way that it all eventually works out.

People have a need for connectedness and belonging
Having just recently talked about it at the XP2011 conference, I noticed that we weren’t the only people to congregate into small circles. For instance, I remember a whole bunch of people from Brazil hanging around together for almost the entire conference. Likewise for a small group of people who worked for the same company in Sweden. It’s a natural thing, particularly in new environments, for people to stay close to those they already have relationships with.

It’s less about you than you think
It is all of these effects combined that lead to ThoughtWorkers aggregating at events. Perhaps it’s also because we tend to be quite loud/opinionated/noisy that it’s more noticeably. Gravitating towards each other isn’t a conscious act trying to exclude everyone. In fact, I know ThoughtWorkers like hearing other opinions, particularly if they’re even more different and based on strong experiences and though happy to contribute to conversation will be welcomed with open arms.

We can get better at this
I know it can be hard approaching a loud, opinionated group of people. I know we can do it better. Being aware of how we’re sometimes perceived, this is how I go about trying to break the perception:

  • Invite others in – If I know someone standing at the edge of a group, I’ll introduce them and explain my relationship to them to others. It helps break the awkwardness and creates more opportunities for everyone to talk about similar interests.
  • Randomly break away – If groups get too large, or hang around too long, I like to break away and meet some new people. I also try to encourage other people to do the same. It’s not only a good way of getting different perspectives, but helps address some of the above issues.
  • Explain to others the contributing factors and perceived effects – By talking people through the above elements, it helps others understand why perceptions come up the way they do. More importantly it lets them decide how they’d like to deal with it

Whilst I can only speak for myself, I do hope that other people can benefit from this by being more inclusive where possible in these sorts of situations.

Book Review: Quality Software Management: Systems Thinking

May 17, 2011 / / 1 Comment

I’ve been interested in Systems Thinking explicitly for the last two or three years. I haven’t had many good books I could recommend to anyone other than “The Fifth Discipline.” Last year, I inherited a wealth of Jerry Weinberg books from fellow geek, Romilly Cocking and just got around to digesting a very classic book, Quality Software Management: Systems Thinking. Weinberg, whether or not you know it, has had a huge effect on our industry. He has written many books on wide ranging topics, and being a participant/organiser of the Amplify Your Effectiveness (AYE) conference continues to influence many leaders.

Anyway, back to the book.

Hard cover books are always a lot more intimidating than their soft covered brethren. Perhaps it’s the sheer bulky that does it. Fortunately the text is rather large and with only about 280 pages of content, easily consumed on a number of continental flights between the “no-electronic gadgets” zone.

I’ll admit that describing Systems Thinking is hard. Walking through, what Weinberg calls, Diagrams of Effects are intuitive when he explains them step by step, however I find it hard to describe the process and never have been very confident in some of the ones that I have used.

The Mechanics of Systems Thinking Diagrams
One tip that Weinberg talks about is thinking about the things in the boxes as things that you could measure (or you do measure) and their relationship between each other. Giving the item in a circle a name has been a challenge for me, and Weinberg presents a heuristic I feel I can make better use of.

Unlike models I’ve seen from places like Soft Systems Dynamics, Weinberg doesn’t use a plus or a minus, and maybe you’ll find his notations work for you. I can’t say they worked or didn’t exactly work for me. I did appreciate the different take on making the secondary, or implicit loops more explicit by attaching repeating loops to the lines they amplify, rather than to the entity they end up with.

In other Systems Thinking Diagrams, people sometimes note a delayed effect, something I was surprised didn’t really turn up in the book to a great deal. I don’t know whether or not this was intentional or not. A new difference I learned though was putting on another notation for diagramming where managerial decision/input affects the Systems Diagram. The way that Weinberg wrote about using this brought a little bit more of a humane aspect to it.

Repeating the role of Mental Models
In the Fifth Discipline, I didn’t really understand the importance of Mental Models related to the point of the Learning Organisation. After chatting to Mark Needham recently on the way that people interpret different things, and seeing how crucial this was to interpreting and drawing Systems Thinking Diagrams in Weinberg’s books, I better understand why these two things cannot be detached. In fact, it was very timely with the question that XP2011 keynote, Esther Derby kept asking, “In what world would this make sense?” to see things from a different Mental Model.

Weinberg tells a really good story about how these Mental Models effect the observation. He recalls a story talking to a manager who’s managed to work out how to distinguish good programmers from the bad ones. The manager starts talking about how he’s noticed how some programmers talk a lot to end users, or to other programmers. A grinning Weinberg, nodding at the manager’s observation slowly stops as he comes to realise how the manager don’t think of these inquisitive, communicative programmer’s as the better ones, unlike what Weinberg (and maybe you and I were thinking). Same observations, different interpretation.

Reconfirmation of in built human biases
We are full of biases that we aren’t even aware of. Many of Weinberg’s anecdotes remind me of some in particular. For example, he talks about how managers running projects that continue to fail, blame it on “bad luck”, or “something out of their control”, whilst taking personal credit for those that do succeed. This is a really good example of the Fundamental Attribution Error.

Things that didn’t work for me
Throughout the book, Weinberg refers to Pattern 1 and Pattern 2 type organisations. Even though he explained them early on in the book, I found it difficult to anchor any real meaning to them by the time I’d finished the book. I would have liked to have seen him give them better names and use them throughout. It’s a minor detail, however I did notice this slowing down my reading.

Summary
I’d recommend this, still highly relevant, book to people involved in IT today. Though it’s published in the early 90s, I’m surprised at how many of the stories are still relevant. It not only explains the basics of thinking with systems using models anyone can relate to. It also explains those systems diagrams that apply to the software problems of today.

Performance is Emergent Behaviour

November 24, 2010 / / 1 Comment

Mark’s tweets got me thinking when I tweeted a short number of responses back at him recetly. Unfortunately twitter isn’t a great place to have a long and well thought conversation and figured I would blog about it like Mark did.

The gist of the conversation seem to float around two positions that seem to be in conflict.

One position states: someone’s behaviour is determined by their environment (or system). This is certainly the view that John Seddon writes about a lot in his book, Freedom from Command and Control.

Most people read this position and (incorrectly) deduce, someone’s behaviour is solely determined by their environment (or system) therefore, it is best to focus on one of them.

Mark makes a great observation that people perform “differently” given they have the same environment. In an environment, sometimes those “differences” may be “better”.

To which I responded in the brevity required by 140 characters, “different strengths and interests at play. Emergent behaviour based on individual and environment.”

Emergent behaviour in this case can be seen as much more than just strengths and interests at play. People are complex systems and highly unpredictable. Each individual goes through many different experiences. Just as an example, everyone’s commute around London is different. Train failure? Tube strike? Traffic on the street? Walking to work? Everyone has different social structures – sleep deprivation from young kids, happiness from a child’s graduation, hard night out celebrating a friend’s send off. Even the weather has a huge impact on people (though everyone responds differently).

It’s rare that I think we are all in the “same” environment all the time.

Add in the topics you’re currently interested in, the events unfolding around you and regardless of the system, and the skills, strengths at play and ambitions, I hope you start to understand why everyone behaves differently. Of course some of those elements in the system have minor impact on the end result yet might explain why some perform “better” (i.e. differently) to others.

Upcoming Speaking Engagements

November 3, 2010 / / 0 Comments

I’ve been terribly busy the last couple of months and it reflects by the lack of any blog posts. So sorry for that. Here’s a short post talking about upcoming speaking engagements.

My first one is for the Collaboration Track at Orevdev in Malmo next week. Titled, “Tightening the Feedback Loop”, I’ll be exploring how interpersonal feedback can be so much more effective. The programme for Oredev looks amazing so I look forward to contributing and participating in the conference.

The second speaking engagement is for the Skills Matter Agile, Lean & Kanban Exchange talking on their “Leadership, Value and Visibility Track”. I’ll be covering, “Making ‘Management’ Work with Agile.

John Seddon Keynote

September 23, 2010 / / 0 Comments

As part of our closing keynote, English based systems thinker and well known author, John Seddon presented his keynote. Interestingly, like many speakers these days, Seddon presented with zero slides and talked about the application of systems thinking and the work that he did.

Having been a speaker with plenty of experience, he definitely came across with plenty of confidence, timing his witty remarks perfectly. Backing them up with personal stories about their success and simple things that others could relate to, I think he definitely hit the mark as a keynote speaker getting more people to think and applying systems thinking to the work that we do.

For a number of us already interested in this field of study and almost active application, I think we were simply glad to hear about how someone has been so successful in its application. This is particularly important around its pragmatic application.

His talk reinforced the importance of helping people see the system for themselves, rather than trying to fix the problems for them and how that will lead to longer lasting results. His talk also highlighted that the work that we do in an agile world isn’t always the best place to focus our efforts because we don’t really want to be delivering the wrong thing faster. Whilst I think many practitioners realise this in the agile community, those with less experience or those simply looking to make money out of a value set do not – and something more people need to understand as it’s adoption grows larger.

Finally as much of a friendly and well opinionated man as Seddon is, he is clear where he stands with the term lean, frequently used in his vocabulary in a derogatory sense. I found this point particularly interesting because my experience, and the ideas espoused by other lean followers in the software community harks back to the value and mindset of lean, rather than the tool junkies and commercial lean people Seddon seems to associate the term with. For me it was an important reminder to validate other people’s association and anchors with words before moving towards more fruitful conversations.

I’d definitely recommend Seddon as a speaker and at least the book I read, Freedom from Command and Control.

Six Years at ThoughtWorks

March 24, 2010 / / 8 Comments

For the first several years at ThoughtWorks I ran an annual personal retrospective looking back at the year gone by. I value celebrating success, making time to reflect and finding ways of continually improving. I ran them for the first few years before collapsing them back into each New Year’s review.

So what has happened six years on?

When I look at first starting at ThoughtWorks, I was just another developer, almost considered a graduate, because I’d only a small amount of real world experience. I worked for ThoughtWorks in Brisbane when we had an office presence, staying there until itchy feet drove me overseas. I could have moved to another Australian capital city, but London ended up much more of a drawcard with so many more opportunities and access to more interesting aspects to life harder to reach in Australia, such as exposure to so many different cultures (music, food, entertainment), personal travel opportunities and the presence of many professional communities.

To this day, I still can’t fathom working with the same company for six years. When I left university, I assumed two years would be the most I would work for in any company. Being lost in one of Oracle’s massive divisions only served to reinforce this view. So what’s changed? Working for a consulting company brings a variety similar to working for many different companies, yet without being tied to any particular one. Each project brings with it plenty of learning opportunities to uncover new contexts, problems and solutions.

Since being based in London, I’ve worked on at least nine projects of great length (a handful of much smaller ones as well). Unlike many of my colleagues, I’ve worked on many projects beyond web technologies (although I’m sure they’re just as fun). Some of these applications integrated with lots of hardware (think RFID readers, barcode printers, scientific equipment), server side REST applications with extremely high performance requirements, lead several development teams, taught fellow colleagues through our lateral training induction programme in India, and coached some very large organisations on appropriately using and understanding agile methods.

In this time, I’ve been fortunate to work with plenty of bright people, both within our own company and at our client, and grown great personal satisfaction by helping others find a passion for learning and taking pride in what they do.

Seeing a variety of situations and working with lots of different people in lots of different roles has lead to significant growth as well. One of the aspects I appreciate the most about ThoughtWorks is the ability to move between roles and develop skills in different areas. Although we’re trying to put a little bit more structure in place, it’s not a place that thinks you have to grow up or get out like many other consultancies.

So the upsides:

Consulting – You develop many experiences and see many environments, giving you better insights into how people behave and how to overcome undesirable behaviour. This first hand experience is invaluable as you apply it to new environments and new clients. Not being independent means I don’t always get choice of what I work on, but I have to be thankful for some of the opportunities over the last six years (partly of what I’ve made it as well).

Growth – Not everyone takes the time to explicitly focus on learning from people around them. This is one of my core principles. Being surrounded by people who think and have great conversations helps me grow. Being put into new situations, slightly beyond my comfort zone increases my confidence and skill set as does dealing with difficult client situations. I can’t thank of many other organisations where I could develop facilitation and coaching skills whilst moving back and forth between hands-on technical work.

Opportunities – I’ve been fortunate to present at a number of conferences over the years. This isn’t an easy path and isn’t one that happens overnight. I’ll be the first to admit, fantastic story telling at the level of Dan North isn’t one of my strong points, but I like to think many people enjoy the experiential workshops I put together. Opportunities are about making the most of what you find yourself in, such as finding yourself, unwillingly, to work in Copenhagen over the summer lead me to finding that lone free booking at Noma, the world’s third best restaurant in the world and enjoying one of the best meals I’ve eaten in my life.

People – ThoughtWorks prides itself about hiring great people. That’s not to say that we always hire perfectly. However I’m glad to be surrounded by other people who take pride in their work, care about learning and passionately applying themselves in whatever they like. I’ve lost count over the years for the number of work colleagues who’ve inspired me to get better at things that I do, and challenged me to better understand the work that I do. I continue to meet more people like this everyday, and am thankful for that dimension.

And the downsides:

Support – Part of not having clearly well defined structures for people as they “advance” make it harder to plan for the right level of support and to time it correctly. I know of some people who moved on by not getting the right support at the right time, and those who failed to get the right sort of support. This isn’t to say that there is no support but it’s a bit random at times. I know that I was particularly let down during my last year although I recognise I have higher tolerances than most.

Travel – I primarily moved across to the UK because of the strong correlation between project work and the office. This has definitely changed over the years. Travel is a necessary part of consulting, yet made harder when traveling greater distances and amplified by the lack of support.

Consulting for clients is different from working in the office – This is definitely one frustrating elements for working for any consulting firm, and I don’t think that ThoughtWorks is any different here, with a different cultural divide between those working in the field and those working in the office. It’s taken me years to see some of the systemic effects, although I’m sure it will be much more before there is something significant I can do about it. Ask me about in person and I’d be happy to run through my current theory.

The key to retrospecting is about learning, so here’s some of the lessons I’ve learned:

Leadership is not about titles – People I talk to see leadership as a role you are explicitly given. I disagree. Leadership implies taking ownership of responsibility and this is true whether or not you are given it or not. It’s not about a role, or a title. It’s about the way you act and the things you say. The leaders I’ve most respected were those that owned the rewards and pitfalls of responsibilities, regardless of it not being an explicit part of their role. The best teams I’ve worked on ensure all responsibilities are taken care of despite the varying titles amongst the people on it.

Everyone is responsible for passing the experiences on – Working for six years for any consultancy is rare, and part of that comes with a certain responsibility of passing on the right culture, and creating the same opportunities for others new to the organisation. Every individual in an organisation should feel the burden of this responsibility. I’m grateful for feedback from co-workers the difference that I make to them everyday. It’s amazingly gratifying to know that I made a positive contribution to people’s growth, even more so when I already hold each one of them in high regard. It’s so gratifying to receive that random text or email from previous co-workers telling me how they’re still doing, or doing things differently as a result of the small investment I made with them.

People move on – People leave companies. That’s a fact of life. The way I look at it, an individual’s needs and wants change more quickly than what an organisation can adopt. I think it’s the organisation’s responsibility to ensure that it does as much as it can to keep people. I think an organisation’s failure is to not to do what it *could* have done to keep them there. This sometimes happens and it’s frustrating. I think we can also get better at keeping in touch with alumni because we definitely aren’t very good with that.

Consulting is a sharp, double edged sword – The change that brings about new experiences and opportunities also often requires travelling or something not quite matching up. Some people in our organisation believe growth will solve these problems, something I also disagree with. I think growth will simply make it much more complex to solve. Having more people on hand simply makes it harder to get the right people to the right place at the right time.

Learning is a lifetime endeavour – I continue to argue how our education systems force us to stop thinking and learning. We focus on teaching (push) over learning (pull) and worse, we focus on absorbing facts instead of thinking. Our environments offer learning opportunities all the time, yet we’re trained to turn a blind eye to them, or to fail to respond to them. Living and breathing agile methods has taught me to learn first, and judge later.

QCon London 2010 Day 1

March 14, 2010 / / 2 Comments

I’ve never been to a QCon before and being run by the same organisers of JAOO and the folks behind the ever popular InfoQ, I was looking forward to being both an attendant and presenter. Lasting three conference days and two tutorial days, this conference focuses mainly on being talked at – quite a different experience to the Agile 20xx and the XP 20xx conferences I normally run workshops/talks at. Being focused on the cutting edge and practical technologies side, I can really understand this because it’s hard to target people with the right level of experience.

Talking to most of the attendees, it also attracts a noticeably different side with the majority of people already in architect or senior developer roles with a relatively smaller proportion of people in other ancillary roles such as PMs, testers or BAs.

Feedback that works
I like the feedback note for the conference, asking people tweet, email or talk to people at the conference. I think some of the feedback mechanisms even worked as we saw a lack of caffeine/water during the breaks on the first day change for the other remaining days.

The Keynote
The first day’s keynote started with the evangelical Uncle Bob Martin. He’s a great speaker and channels a lot of opinion towards the crowd wandering back and forth on stage. I saw a version of this at the Agile 2009 conference. I’m glad he adjusted it somewhat more appropriately for this conference. He talked about some good principles that should be followed after a few bumpy technical glitches. He is all about the drama (which I guess is part and parcel of a keynote) such as showing us a video that scrolled through a single java class for something like two to three minutes backed up by a song from the movie from 2001 (thanks Ola!) that almost sounded like the flight of the bumblebee. The point of this showmanship was to demonstrate how we can sense bad code visually without even looking at the specifics. He went through a number of his mantras such as “The Boy Scout” rule, leaving things better than how you found them, or that functions should be no more than four or five lines long.

Whilst I don’t think I learned anything new, Uncle Bob Martin was entertaining and had good things to say, despite how preacher-like he comes across.

Track: Architecture’s You’ve Always Wondered About – Session: BWin – P5 a future proof poker platform
The rest of the day was split into six different tracks. I went to the first of these and was truly disappointed. The two presenters came from BWin, apparently one of the largest poker and gaming sites in Europe. They spent half an hour talking about their problems of performance (many of the -iliites) and where the history of their application came from. They even had to include a three minute video from their marketing folks. They finally flashed up a screenshot of their architecture diagram which I think everyone had come to hear about it. Unfortunately they moved onto the next screen very quickly and said that they couldn’t actually talk about their architecture. How disappointing! Indeed this might have been an “Architecture You’ve Always Wondered About”, and after this session was one to still, indeed, wonder about it.

They proceeded to pick a single example about two processes that concurrently wrote and read from the same database table and their architectural change simply transitioning it to a disk persistent queue and the reporting service reading from that queue and writing to its own database. Neither very profound, or a very interesting tidbit that failed to give the audience any more insight into any interesting part of how they architected their system.

I found it interesting they spent a long time (something like 250 man years) rewriting this version of their architecture so I asked the question about how they went about moving from their old to their new platform at which they pretty much described a big bang approach – neither iterative or incremental. Pretty disappointing.

My lesson learned from this: Regardless of how pretty your slides are, make sure your abstract matches what you’re going to actually talk about.

Track: Dev and Ops: A Single Team – Session: Devs and Ops Cooperation when the Worst Happens
My next session was much more fulfilling with Michale Nygard (author of Release It) describing some of the stories that were the basis for the book but wouldn’t have been publishable. Michael is really down to earth and happy to chat about many of the details behind the book. It’s really obvious that he is also a very pragmatic person, understanding that models are just that and recommending people look into the details because there is often something much more complex underneath.

Many of the things that Michael talked about also resonated very strongly with ideas that I’ve seen on applications. Many of them included focusing on ensuring documentation artefacts should be tested by those who will consume them. As he put it, “UML is virtually useless to the deployment and operations team”. Other gems included, “From a high enough view, everything starts to look the same”

His stories also reinforced the importance of having a ubiquitous language will all members of the company in the shared domain. One of his most successful rescue missions dealing with a production problem only worked because the architect (on the dev side) and Michael (on the ops side) understood enough to really communicate the real problems. Michael also kept (understandably) hammering home the point of lack of information on both sides really hurts the problem solving process.

A lot of Michael’s stories also described their successes working around the existing (organisational) systems in order to deal with the problems at hand. To me, this was just another great example of organisations that structure themselves for efficiency over effectiveness.

I like the way that Michael finished off his talk as well, focusing on the fact that you’re not just trying to build software, that you need to care about the organisation (and I would also argue, the systems and procedures in that organisation) that support the software. Design them for effectiveness, not efficiency.

Architectures you’ve always wondered about: Facebook
The next session I attended was by Aditya Agarwal (one of the engineering directors of Facebook). He shared some great insights and lessons learned into what things Facebook did that got them to where they were. Admittedly they had some strange choices like writing something that converted PHP into compiled C++ and using MySQL is a very “reliable bitstore”.

They have a lot of great things to say, like being very proud of the low number of engineers ratio to actual users. Like Alistair, I’m puzzled why they’re secretive of the exact number of their employees.

Aditya has some good things to say and although he means well, I don’t support everything that he says. it’s obvious a lot of what he says is based on a start up culture. Things like, “don’t worry about it until it becomes a problem” encourages the recklessness we see in many software companies. Same thing about the choice of programming language such as “every programming language will have problems at our scale”.

On the plus side, I was pleased to hear them encouraging the innovative engineering culture that I don’t see in many organisations.

Track: Non relational DBs and Web Oriented Data – Session: Social networks and the richness of data: getting it done with
After going through my notes the most interesting tidbit was about using a partitioning mechanism to deal with data updates based on the number of connections. There was plenty of buzzwords (both internal and external) that I think I had a hard time fitting it all together. Some things I’m going to look at include:

  • Bit versus bloom filters – Not familiar with this term or how to use it.
  • Tools – RESTeasy (I now see it’s a JBoss project). Redis and Voldemort – something they used heavily all over the place.

That’s about all I got out of this session though I’m not sure if it was about the lack of familiarity with the tools, or the excessive use of acronyms and unfamiliar terms or just plain tiredness.

Track: Functional Programming – Session: Demystifying Monads
Josh Graham did a great job stepping into fill in for his ill wife talking through some of the different ideas behind monads. I haven’t done functional programming since university and I’ll be the first to admit Monad’s are still a mystery to me but I came away with some key learnings.

Firstly, to understand monads properly, you really just have to see several examples in action. There’s a high barrier to entry because it means:

  1. Learning a new language
  2. Learning a new development environment
  3. Playing with plenty of examples

When I find some time, I’ll do those. In the meantime, I understand a bit more about the properties of a monad, and that they can be a powerful abstraction for functional languages.

Final keynote – Dan Ingalls: Forty Years of Fun with Computers
For being so late in the day, this was a very entertaining keynote. Just like any modern day small talk person, this entire demonstration took place in the Squeak development environment. Dan demonstrated some interesting and interactive elements.

I had a few key takeaways including:

  • We’re really bad at learning the lessons from the past. Partially because we don’t have enough storytellers and that our generation doesn’t listen very well.
  • I’m going to read this article at some point.

Is the term ‘Agile’ still useful?

December 10, 2009 / / 4 Comments

This year proved interesting for those in the agile community, or at least for me. The most commercialised agile methodology lost one of its largest figureheads, and a new community of thinkers emerged focused on prioritising a practice often implied or described as optional in other methodologies. What I found fascinating about a new community forming is that in finding its own identity, it naturally results in denouncing ties with existing communities (to a certain degree) and comparisons about whether or not they are “agile”.

This lead me to ask myself, “What is wrong with agile?” To better understand it, I went back to finding out why “agile” first started. From my understanding, a community of thinking practitioners (not just thinkers) coined the phrase “agile” to unite people working in different ways to help identify with each other. The actual methods for working in an “agile” fashion existed well before they coined the term.

I respect and heartily thank this group of thinking practitioners for coining the term “agile”. A simple word acting as an umbrella that encourages people to swap ideas between communities. I recognise this same “vagueness” that draws people together also makes it difficult for newcomers to identify with what it means.

Look at how other communities relentlessly protect their set of practices, branding and declaring you are or are not doing methodology X or approach Y, particularly when reinforced with certification programs. I’ve realised this same protectionist attitude acts as a wall to new ideas spreading between people and organisations that could be beneficial.

I vouch that the term “agile” remains useful. Let us not forget the original intent behind the word. Let us embrace and create opportunities to continue welcoming all thinking practitioners from different backgrounds to connect and swap ideas and experiences to be more effective and successful.

Respect is in the currency of geeks

A work colleague pointed me out to this fascinating article called, “The unspoken truth about managing geeks” that I think anyone working in IT needs to know about.

There are some great bites of information in there that I picked up including:

  • Avoid laying blame on stereotypes and look at the system that drives out certain behaviours (such as those factors amplifying stereotypical behaviour)
  • Geeks trust people who help get the job done. Geeks find ways to work around people who don’t.
  • Unlike in almost every other area, it’s often not how you say something that matters, it’s what you say. Maybe it’s because of logic but geeks detect when things don’t quite add up.

I suggest you read everything in the article. I don’t necessarily think all of it is accurate at all of the same time but it’s well written and gives people insight into why geeks often behave as they do.
