As Luis Abreu points out, I don’t think there is a precise definition of what DDD actually is but for me the essence of DDD is still the same as when I compared it with OO i.e. Domain Driven Design = Object Oriented Programming + Ubiquitous Language.

I think that Mark is on to a very useful and succinct definition of DDD, yet I feel he overlooked the Law of Demeter. Building on Mark’s definition I’d define DDD as Domain Driven Design = Object Oriented Programming + Ubiquitous Language + The Law of Demeter. While some would argue that the Law of Demeter is implicit in Object Oriented Programming (or at least of OOP of the good kind…) I believe that it is important enough for successful Domain Driven Design that it should be explicitly mentioned.

Looking forward to your comments!

Google Maps' Street View indicator is now a Panda bear

I’m wondering if this is happening in the US version of Street View or only here in Australia.

You are in charge of a project for developing an internal application at a large brick-and-mortar company. Your target audience for the application are the employees of a critical business department (here on, Department X). The customer representative is the head of that department and is glad to be involved in the planning process and domain knowledge sharing as well as story analysis, hand over and sign-off; Seemingly, an ideal ‘customer’, here on- Mr. X.

Yet at scope planning meetings for the project, Mr X. is insisting that all the feature requirements are ‘Must Haves’ and while he agrees that the order of development should be based on ‘higher business value first’, he refuses to de-scope any features, insisting that due to external circumstances their delivery must occur by the project’s go-live date.

You would accept Mr X’s proposal if he would be willing to increase the budget for project to allow resourcing to meet these requirements. Great! He is willing! But wait — he can’t. Why? Because the project is funded out of the IT budget and not out of department X’s. This is a lose-lose situation, as the project is now set to fail in the eyes of the customer and in turn, harming the IT department’s reputation – Department X is not getting what it wants, even though it is willing to pay for it. 

The root cause here is the divergence between the beneficiary of the application and the entity that pays for it. The two may have differing goals, priorities, political considerations and machinations and whilst they both work towards the same organisational goals, these two entities operate under different business units with sometimes divergent operating considerations.

Budgeting models for IT departments seem to be based around IT as infrastructure — which makes sense for, wait for it… infrastructure: network, VOIP, hardware and the like — but repeatedly fails for business applications.

While it makes sense for IT departments to harbour the core capabilities and knowledge for software development (….development infrastructure…) it should only act as a cost-effective contractor to the business when developing business applications. Business applications projects should only be undertaken as part of a business case, they should have clear ownership by the benefiting entity and not the IT department.

When analysing teams and projects that clearly ‘smell’ and have a hard time changing, my personal experience indicates that in the majority of cases, following the smell to its source leads to this root cause. This is more pronounced in bigger organisations and seems to be proportional to the level of organisational separation between the project beneficiaries and the IT department. More so — this is almost always the underlying organisational issue that makes it difficult to implement agile methodologies.

This lesson was learned by many organisations, but unfortunately not all — and it should–

 The ‘IT department pays’ model of application development should die.

He had a chance to try out using the “Connexion by Boeing” Wi-Fi service on his Lufthansa flight. The service is unfortunately being terminated at the end of the year, so this is probably going to be his last chance to have a go.

There’s a small bright side which is that use of this service has been made free until it is terminated.

Presumably a spammer has taken his list and “cleaned” it against the blue list, then done a diff? Like I say, I’m amazed it’s taken so long.

Quite clearly this spammer has only sent this eMail to people that were already on his list and matched against a Blue Security hash. Thanks to JohnSolver for thie link to Blue Security’s response, their web-site is slow… Maybe a DoS by the same spammer to go along with the FUD?

One response to the body of the spammer’s text:

BlueSecurity lists a USA address as their place of business, whereas their main office is in Tel Aviv.

So what? Many Israeli technology companies incorporate in Delaware for taxation reasons. The next line is clearly defamatory with no real value:

BlueSecurity is run by a few Russian-born Jews, who have previously been spamming themselves.

Their heritage is beside the point. Also even had they were spammers previously, the spammer behind this eMail has no right to make anonymous accusations.

From: GOLDEN HOLLINGSWORTH

You are being emailed because you are a user of BlueSecurity’s well-known software “BlueFrog.” http://www.bluesecurity.com/

Today, the BlueSecurity database became known to the worst spammers worldwide. Within 48 hours, the database will be published on the Internet, and your email address will be open to them all. After this, you will see the spam sent to your mailbox increase 10 – 20 fold.

BlueSecurity was illegally attacking email marketers, and doing so with your help. Many websites have been targeted and hit, including non-spam sites. BlueSecurity’s software has been fully analyzed, and contains an abundance of malicious code. This includes: ability to send mass mail to users; the ability to attack websites with Distributed Denial of Service attack (DDoS); the ability to open hidden doors on any machine on which it is running; and a hidden auto-update code function, which can install anything on your computer and open it up to anyone.

BlueSecurity lists a USA address as their place of business, whereas their main office is in Tel Aviv. BlueSecurity is run by a few Russian-born Jews, who have previously been spamming themselves. When all is said and done, they will be able to run, hide and change their identities, leaving you to take the fall. YOU CANNOT PARTICIPATE IN ILLEGAL ACTIVITIES and expect to get away with it. This email ensures that you are well aware of the situation. Soon, you will be found guilty of computer crimes such as DDOS attacking of websites, conspiracy, and sending mass unsolicited bulk email messages for everything from viagra to porn, as long as you continue to run BlueFrog.

They do not take money for downloading their software, they do not take money for removing emails from their lists, and they have no visible revenue stream. What they DO have is 500,000 computers sitting there awaiting their next command. What are they doing now?

1. Using your computer to send spam ?
2. Using your computer to attack competitor websites?
3. Phishing through your files for your identity and banking information?

If you think you can merely change your email address and be safe while still running BlueFrog, you are in for a big surprise. This is just the beginning…
