Pair Programming and Formula One

When I was working and developing software in F1, people from other departments of the Racing Team were surprised to see two software engineers working and coding together at the same PC. The CTO used to mention the example of the Pit Stop where many engineers works together at the same car to refuel, switch tires, fix settings as fast and as perfectly as possible. Another example mentioned was the operating room where many surgeons work together to avoid mistakes and keep the surgery short. Not to mention that a real surgical team visited the Racing Team to...

The 7 fundamental principles of Software Requirements

When trying to reach a moving target, making a good plan is extremely hard, while planning and executing small steps within short inspect-adapt loops is extremely easier. The faster the target is moving, the more increasing inspect-adapt frequency is beneficial/advantageous/profitable over perfecting the plan. After all it is not possible to adapt the reality to a plan, it works better to adapt the plan to the reality. Here 2 stories: Speed of Iteration Beats Quality and how Paul MacCready won a million dollars prize When trying to deal with unknowns & uncertainty & disagreement, making a good forecast is extremely hard.

Keyboard Jedi on Windows7 64-bit

After some work finally got the Keyboard Jedi 1.5 tool by Roy Osherove to work on Windows 7 64-bit. Had to use the last version, 1.2.0.10, of the Global System Hooks library by Michael Kennedy from here:  - http://www.codeproject.com/KB/system/globalsystemhook.aspx Then did as described by James  Kovacs here: - http://jameskovacs.com/2008/04/25/keyboard-jedi-on-vista-x64/ to force it to run at 32 bit and to reference the new version of the Global System Hooks library. Download it from here: http://dl.dropbox.com/u/11163041/keyjedi-Win7-64bit.zip This build requires the .NET Framework 4.0, you can repeat the steps described here, using the original exe, in ordert to build it with...

The Texas Sharpshooter Fallacy && Retrospective coherence

Do pay attention to The Texas Sharpshooter Fallacy when looking for Retrospective coherence to avoid placing artificial order over natural random chance. When you do the Retrospective meeting, when you do the root cause analysis, when you try to recognize patterns and search for meanings while looking at data collected from your teams feedback loops, when you try to generalize what worked in your team and you try to replicate it in other teams.

Clean Code III Functions

One of the training on coding that I usually have with new teams is about proper naming of methods and arguments, and writing short methods. This article explain quite well all these things and add more insights to move to the next level: - choose names of Functions/Methods that are the verbs - choose names of  classes are the nouns of the DSL language that is used to build your system. The art of programming is, and has always been, the art of language design. Read these slides by Robert C.

Ports and Adapters architectural pattern

Create your application to work without either a UI or a database so you can run automated regression-tests against the application, work when the database becomes unavailable, and link applications together without any user involvement. Known also as: Hexagonal Architecture Read the full description here: http://alistair.cockburn.us/Hexagonal+architecture I know that my Italian friends Matteo Vaccari e Antonio Carpentieri have presented sessions about this topic at the London XP Days and in other agile events, so they can be trustworthy source when you want to ask questions about this topic.

Software Engineer o PR Microsoft?

Parto dal post The Future of Silverlight del Silverlight Team Blog per suggerire una opportunitá di miglioramento. Silverlight é stato un prodotto che ha esplorato delle possibili aree di innovazione e che ha mantenuto le opzioni aperte in attesa di scoprire come si sarebbe sviluppato il futuro del HTML 5. Una strategia di innovazione che invidiamo a Microsoft e vorremmo fosse adottata anche dalle aziende per cui lavoriamo. Nessuna delusione quindi per un naturale cambio dei piani, anzi un hurrá per Microsoft che ha trovato la strada migliore che porta verso il futuro prossimo. Il suggerimento va invece a...
