As a product guy, working on mobile devices, I'm pretty impressed by this demo.
Simple, with what you need in your day to day life. Microsoft is back on track.



Thanks to Chris Pirillo for the video.

Visual design patterns

Most of the time, when guys were explaining the role of the software architect to me, I was not able to believe it would be possible to organise software development on such a division of responsibilities. I always feel the architecture is a discipline each member of a team should embrace.
The "Design Patterns Quick Reference" from Mc Donaland is really useful because it allows the team to speak about the most appropriate choice in front of this great summary.
But a common pitfall with these pattern design concepts is the fact people will over design and move to a solution too complex.
One solution resides in the Test driven development principles where after coding the test and writing the code for them to pass, there is the refactoring step.
This is the good moment to consider inserting a design pattern.
Make things work, then focus on building maintainable code.

Adopt Social media

Adopt Social media, don't buy but earn attention.

Why do you still invest money in marketing areas where you are sure to get nothing in return?
Fear of change?

While I agree with the presentation "Social media marketing explained in 61 words" by David Meerman Scott, I still do not get how I could apply these concepts to niche markets, like the one I currently work in.
Enjoy the show where you'll be explained what is introduced on David Meerman Scott's own blog:
"
You can buy attention (advertising)
You can beg for attention from the media (PR)
You can bug people one at a time to get attention (sales)
Or you can earn attention by creating something interesting and valuable and then publishing it online for free: a YouTube video, a blog, a research report, photos, a Twitter stream, an ebook, a Facebook page.
"

David builds his argurment with real examples (links in sources) he has met these last years and jokes about the Gobbledygook you can find on marketing product web page.

Agile Lyon 4th

On Tuesday 9th February, the 4th Agile Cara session occurred in Lyon.
I was happy to see new faces, but on the other hand, it is hard to know why people are not regularly attending our by bimontly sessions.

Alexandre presented us a subject he had enjoyed at the Orlando Scrum Gathering : Mapping Change Battlefield by George Schlitz & Giora Morein.

Organisation change management is well known and is treated in many books like Leading Change (John P KOTTER) and online articles (Pierre Collerette), but in this case, the presentation has been constructed based on a Military battle Campaign metaphor.
Even the subject is presenting a way to identify the resistance when it comes to proposing Agile adoption, these concepts are suitable for many other management situations. The main idea is to build an organisational map where influencers are red (Enemy of a move to Agile), green or white (Neutral) and then to draw arrows of influence between them.
The result is clear, effective and could easily lead to the definition of an action plan to neutralise the Enemies.

Refactoring for sale

Among the technical list given by Mikael Boman in his post dedicated to product owners, "Practice #4: Refactoring" is for sure, the most difficult to agree with. Version control system, Continuous integration, Automated testing are concepts around tools, consequently their deployment has a visual, understandable, palpable result, so there is no worry justifying their costs.

If you don't get the Practice #6: Collective code ownership, wait for a few years until developers leave your company and then you will get it.

Simple design:
While the indicated article focuses on product owners, the simple design concept is obvious to many of us, but developers could feel it as a bridling of their creativity. While we all need to establish a software knowledge culture, where ideas around code design and patterns are understood, we face a dilemma when it comes to asking for simple creation. I didn't find a good way to recommend, but practices like pair programming and code review can mitigate the ugly and the glittery code. A developer conversation while looking at the code, will free the product from the lack of conception or avoid the all "design patterns" in one "software product" idea.

Refactoring:
Previous to entering into the agile/lean world, I didn't find a proper solution to justify a moment to improve the code. Then, based on Lean concepts, I felt desperate because spending time on refreshing the code could be understood like a waste. But the only reality resides in understanding the technical debt and the product complexity.
Some people will argue the refactoring must be embedded in the development tasks and will state that concerned developers will perform this activity by themselves. But such behaviour could hide the iceberg from the product owner or give him a great argument to play the ostrich.
Refactoring must be understood, and the product owner must commit to spring cleaning the code.
If some tasks related to code refactoring are present in the product backlog, it means:

• Developers have an understanding of the code, so the concerned component is not something anybody would touch anymore due to its ugliness, but only a huge number of code lines that smell bad.
• Product owner has stepped back, understood the complexity of the component and admitted the technical debt must be lightened,
• The regression linked with the refactoring will be mitigated by guardrails, like unit tests or user scenario rechecks by testers. Because the testers will have to valid the refactoring tasks, they would have discussed the impact and the use cases affected by this work with the developers. They will not discover the regression nightmare later after a refactoring decided by the developer on his own.

Enterprise social software

Last century, I used to send to my colleagues a constant flow of emails with links I considered relevant to our work. Experience has shown me that pushing information to people doesn't mean they assimilate the essence of the content. Worse, if you send too many messages they will get ignored and after filling up your colleagues' mailboxes, they will tend to automatically bin them. Pushing information is definitively a waste of time for both the sender and the receivers.

While the enterprise's knowledge is supported by the enterprise content management, the availability of web tools has led many organisations toward Enterprise social software.

A blog for a project, for a service or for the general news, are surprisingly adopted without an effort of persuasion, where the traditional content management tools have failed. Easy to use, and effective with a small amount of writing are the main characteristics of this technology.

A wiki is a group of web pages that people can edit just by clicking on a button. Current wikis have a WYSIWYG interface that most users are comfortable with, a good improvement from the first wiki.

But wikis are the best for collaboration. Watch the following picture directly copied from the wikinomics blog and you see which waste has been eliminated.



















Wiki adoption in the Enterprise is something different from the uptake of blogs. If you want to succeed in deployment of wikis, you will need to step back, get the good people and avoid classic mistakes and that's what you'll find on the wikipatterns website.

Interacting with both worlds. The end of the old screen?

Pranav Mistry demos several tools that help the physical world interact with the world of data -- including a deep look at his SixthSense device and a new, paradigm-shifting paper "laptop."

Fruit-Shaped Sticky Notes

We have been told to use sticky colored tickets as kanban, but frankly, even if the result is damn effective, the aspect is closer to a moulting bird than a rational visual tool. Our building design quality is contributing to sustain or maybe to enhance our amenities, likewise our creativity. Therefore why not display the pace of our inspiration by a tree of sticky fruits?

Without a doubt these Fruit-Shaped Sticky Notes, called “KUDAMEMO” by D-BROS, coming from Japan must be an answer to the sad visual board we have now.

Introduction to Lean Manufacturing

If you never heard about Lean, have a look at the following video from the Gemba Academy.

From TED Dan Pink on the surprising science of motivation

Career analyst Dan Pink examines the puzzle of motivation, starting with a fact that social scientists know but most managers don't:

• One: Those 20th century rewards those motivators we think are a natural part of business, do work, but only in a surprisingly narrow band of circumstances.
• Two: Those if-then rewards often destroy creativity.
• Three: The secret to high performance isn't rewards and punishments, but that unseen intrinsic drive. The drive to do things for their own sake. The drive to do things cause they matter.
  

Building Large Distributed Systems

Today, the computer world has two big trends: mobility and cloud computing.

If you want to have a feedback about the second one, have a look at the Jeff Dean presentation: Designs, Lessons and Advice from Building Large Distributed Systems

I found the google protocol buffers "a language-neutral, platform-neutral extensible way of serializing structured data for use in communications protocols, data storage",
pretty interesting.

Google Reader with colors

Google Reader is probably the best free online RSS reader available today. Due to its simplicity and its minimalist interface, sometime you wish you could have colorized at least its background.
Matt Cutts tell us here below how to display a hidden function: In your Google Reader press keys: Up arrow, Up arrow, Down arrow, Down arrow, Left arrow, Right arrow, Left arrow, Right arrow, B key, and lastly A key.
And ....



This is my nerd's consern of the week.

Hanselminutes

The quantity of material around agile is soaring and I will share with you several videos I have watched these last 2 months.
As a permanent quality resource, I recommend the podcast, The Hanselminutes.
Because of the diversity of his guests, Scott Hanselman gives me a lot of input around the current technologies, services and books.
