Looking at the formats of European country international bank account number (IBAN) codes, I noticed that the IBAN length didn’t seem to be significantly correlated to the country’s population. Could it be related to the country’s IT maturity? I tested that using as a proxy the EU Digital Economy and Society Index, and the results were stunning.

Here are my notes.
Continue reading "Pia Betton on Service Design"Increasingly, software is provided as a service. Managing and controlling the service’s provision is tricky, but tools for service orchestration, such as Rundeck, can make our lives easier. Take software deployment as an example. A well-run IT shop will have automated both the building of its software using tools like make, Ant, and Maven and the configuration of the hosts the software runs on with CFEngine, Chef, or Puppet (see the post “Don’t Install Software by Hand”). Furthermore, version control tools and continuous integration will manage the software and the configuration recipes, handling developer contributions, reviews, traceability, branches, logging, and sophisticated workflows. However, these tools still leave a gap between the software that has been built and is ready to deploy, and the server that has been configured with the appropriate components and libraries and is ready to run the software.

Running a top-notch software development organization used to be a capital-intensive endeavor, requiring significant technical and organizational resources, all managed through layers of bureaucracy. Not anymore. First, many of the pricey systems and tools that we developers need to work effectively are usually available for free as open source software. More importantly, cheap, cloud-based offerings do away with the setup, maintenance, and user support costs and complexity associated with running these systems. Here are just a few of the services and providers that any developer group can easily tap into (you can find many more listed here):
Continue reading "Developing in the Cloud"In the 1920s, the Ford Motor Company embarked on an ill-fated attempt to establish an industrial town in an Amazon rainforest as a way to secure a cultivated rubber supply for its cars’ wheels. At the time, it already owned ore mines, forests, and a steel foundry to produce the raw materials for its cars; today, it buys from external suppliers, even its cars’ electronic control units. How do these two phases of the automotive industry’s history relate to the way we currently develop and adopt infrastructure in our profession?
Continue reading "Bespoke Infrastructures"The environment we work in as developers can make a tremendous difference on our productivity and well-being. I’ve often seen myself get trapped in an unproductive setup through a combination of inertia, sloth, and entropy. Sometimes I put-off investing in new, better tools, at other times I avoid the work required to automate a time-consuming process, and, also, as time goes by, changes in my environment blunt the edge of my setup. I thus occasionally enter into a state where my productivity suffers death by a thousand cuts. I’ve also seen the same situation when working with colleagues: cases where to achieve a simple task they waste considerable time and energy jumping through multiple hoops.
Continue reading "The Frictionless Development Environment Scorecard"We hear a lot about the adoption of open source software, but when I was asked to provide hard evidence there was little I could find. In an article I recently published in the Journal of Systems and Software together with my colleague Vaggelis Giannikas we tried to fill this gap by examining the type of software the US Fortune 1000 companies use in their web-facing operations. The results were not what I was expecting.

A number of people asked me for more details; if you're interested read on.

It was one of the most inspiring meetings I've attended for some time. These are my notes from the meeting.

I'm sure that many readers of this blog have read the Manifesto for Agile Software Development. Having worked in government over the past year, I wondered how a similar manifesto for government, created by a group of people who would radically want to improve existing structures, would look like. Here is my take.
Continue reading "Manifesto for Agile Government"During the past six months I've been drowning in email. I spend a large part of my day responding to email messages and filing incoming messages I consider important. Yet I'm falling behind and this affects the quality of my work: I sometimes delay responding to important messages. Followng Peter Drucker's dictum "If you can't measure it, you can't manage it", I decided to write a tool to analyze my incoming and outgoing email messages.

Continue reading "Ron Heifetz on Crisis Leadership"I drown in email and my aspirations for handling it are becoming increasingly lame. In the 1980s my goal used to be an empty mailbox at the end of each session. During the 1990s the goal became to empty the mailbox by the end of the day. But tasks I couldn't complete within the day accumulated, so in the 2000s I just tried to have only so many messages as could fit in a window without a scrollbar, so that I could immediately scan what I had to do. Nowadays my modest goal is to keep the size of my mailbox below 100 messages, and I succeed in that only half of the time.
Continue reading "Email's Ten by Ten Law"Parents spend years trying to teach their children to be polite, and some of us had to learn at school how to properly address an archbishop. Yet, it seems that advice on courteousness and politeness in technical communication is in short supply; most of us learn these skills through what is euphemistically called “on the job training.” With enough bruises on my back to demonstrate the amount and variety of my experience in this area (though not my skill), here are some of the things I’ve learned.

Some addresses, like Wastington, DC are simply annoying, while others, like Vancouver BC V6T 1Z4 United States, are mildly amusing. It's clear to me that the database has been populated by the massive application of a cheap labor force. This is happening all too often, and I think it is a mistake.

I was sure this wasn't always the case, so I dug up the corresponding the top-25 projects at the beginning of 2006 to refresh my memory. The differences are profound.

Kaplan, a Professor of Leadership Development at the Harvard Business School, on using strategy maps and balanced scorecards in a strategy execution system. Dr. Kaplan managed to distill 15 years of research and its application by the world's leading companies into a fascinating 90 minute talk. These are my notes.

I believe that the Commission's approach towards research planning and funding is fundamentally wrong.

It was a unique experience, in which I witnessed the sophistication of modern production methods, and the most well-organized complex human undertaking I have seen first hand. The factory literally runs like a clockwork, eerily bringing to my mind the descriptions of Mars's factories in Bogdanov's science fiction novel Red Star.

From January 1st 2006 passports are no longer issued by the prefectures, but by the police, and from August 26th passports include an RFID chip. The new process has been fraught with problems; many of these difficulties stem from the IT system used for issuing the passports. On December 12th, the Greek Ombudsman (human rights section) issued a special 22-page report on the problems of the new passport issuing process. The report is based on 43 official citizen complaints.

I spent the morning studying some fairly tricky technical documents. Within that interval I often caught my eyes glancing to the top right of the Adobe Reader's display window where an advert button flashed as it changed its content. Needless to say, this change of focus interrupted my train of thought, and got me out of "flow mode".

Yesterday I mapped the sales rank to actual sales, and correlated those with significant events and hits on the book's web page.

There I gave a tutorial on tooling with open source software, and delivered a talk on Global Software Development in the FreeBSD Project. It was an edifying trip.

I've found that in order to increase the efficiency of my work I need a moderately large selection of pending tasks. This allows me to match the type of work I can do at a given moment with a task in the most optimal way.
