I have a Request class based on the same Entity in my Domain. It currently only has property definitions. I'd like to add a method for checking a duplicate Request which I'll call from my controller. Should I add a method called CheckDuplicate in the Request class? Would I be violating the SRP? The method will need to access a database context to check already existing requests. I'm thinking creating another class altogether for this logic that accepts a datacontext as part of its constructor. But creating a whole new class for just one method seems like a waste too. Any advice?
Not Using Long-tail Keywords? Long-tail keywords are a god-send to anybody who uses search engines for traffic. This goes for both paid traffic and organic traffic. A long-tail keyword is a key term that's more than three words long.
In an oriented-services enterprise application, isn't it an antipattern to mix Service APIs (containing interface that external users depends on) with Model objects (entities, custom exceptions objects etc...) ?
According to me, Services should only depends on Model layer but never mixed with it.
In fact, my colleague told me that it doesn't make sense to separate it since client need both. (model and service interfaces)
But I notice that everytime a client asks for some changes, like adding a new method in some interface (means a new service), Model layer has to be also delivered...
Thus, client who has not interested by this "addition" is constrained to be concerned by this update of Model... and in a large enterprise application, this kind of delivery is known to be very risked...
What is the best practice ? Separate services(only interfaces so) and model objects or mix it ?
If you're an individual or an organization planning to employ a search engine optimization professional, you might first want to consider the possibility of doing this work yourself. Certainly, a search engine optimization consultant can boost your site and perhaps help save you time and effort, yet the fact is that SEO is hardly an advanced science, and there are just a handful of authentic professionals within the field. So, if you depend on somebody else to be in charge of your search engine optimization, there's a high probability that the person will not possess a great deal more knowledge than you. And if you lack any knowledge, all the relevant information is easy to obtain.
The return on investment of your website depends on the SEO Company you go for. SEO firms generally offer various SEO packages. The selection of the same depends on what kind of marketing techniques you are looking for to electrify the chief search engines. SEO packages are very beneficial and at the same time affordable too. Multiple services are offered in a single package. Depending on the type of your website you may choose the best one.
These days, it's the demand for the Internet that is exactly going too high. Over the years, the Internet has managed to establish itself as the most effective marketing platform for many businesses. On the other hand people across the globe now prefer to opt for the Internet in order to grab their necessary details or information easily.
How many times have you found a tool, gadget or tutorial online that was just so useful or so cool you had to pass it along to your friends or your customers? The truth is that these types of products are extremely popular because they either solve a problem or provide great entertainment value.
I have clients that own small businesses that come to me and say, I want my site to show up #1 in Google for "my businessnamexyz". This is a very common question I get all the time and if I was an SEO specialist looking to make a fast buck and not build valuable long lasting relationships, this avenue could quickly be taking advantage of.

I work in a company who uses their web-hosting as their email provider, they use it for normal send, receive and basic contacts management, they use it in customers support, sales and marketing, I would prefer to use a dedicated or professional email hosting instead for this type of work.
So for business use is it safe to use the email hosting that is included with hosting package or go with a professional email provider?
My wife has a small business that she wants to offer a free WiFi hotspot in. She suggested opening up our private 'net connection to the customers - T&Cs of our internet provider and thoughts of random people viewing kiddy porn floated through my mind.
So, first action will be to get a separate internet connection. But I have no experience of setting up a public WiFi connection. What considerations should I make with regards to:
WAP
Security
Access logging?

I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application on top of this stack should be architected.
The main issue I have is that in most of the demos I've seen most of the business logic ends up as DataAnnotations and custom validations in the RIA Services domain service class. This seems inappropriate to me. I view the domain service as basically a glorified web service that happens to make it easy to push information to the client. But most of what I've seen seems to orient the domain service as the main source of business logic in the application.
So, my questions:
What is the best location for business logic (rules, validations, behaviors, authorization) in an application using this stack?
Are there any guidelines published at an architectural level for using this stack?
My questions pertain to large, complex, and long-lived applications. Obviously for an application of only a few screens this is less of a concern.
Edit:
Another thing I meant to mention is that obviously you can make the domain service class stupid, but then you lose a lot of the automagic entity information (e.g. validations) being pushed to the client. And then if you lose that is there any point to using RIA services?
