Would anyone be willing to give me some constructive feedback on my most recent article?

All constructive feedback is genuinely appreciated.
Thanks

Actually articles are expected to be posted here on CP, not simply advertised here...
|
|
|
|

Why not you link your CP account to your blog - it will give you a larger publicity and us something to read...
Also you will get all the feedback you ever wanted (I don't know about constructive  )

The truth? Lots of words (with rather poor grammar) but very little useful meaning in them. Your title is "ARCHITECTING BIG DATA SOLUTIONS", but I did not see anything that would actually help to do that, as it is such a high level overview. Sorry to be so negative but I think you would do well to go back and review it from a reader's perspective.

He asked for constructive feedback, yours much like destructive...

There was nothing constructive that could be said about it.

Thank you all for your comments. I am working on becoming a better writer so your comments, as long as they help me do that, are welcome. "The harsh words of a friend are better than the kisses of an enemy."
I am starting to think that this may not be the place for this type of article. My audience was the 'C' level suite to provide some general thinking guidelines. They don't want the same level of details that we as developers need. Should have probably put that in the initial request.
Again thank you for taking your time to help me. I appreciate it.

You should also appreciate that this forum is not the place for this. If you wish to write articles then you can submit them by following the Article Submission Guidelines[^]. They will then go into the general review queue where CP members can review and provide feedback, without further prompting from you.

I wonder what optimization algorithm should be used for such a problem:
x: independent variable
y: dependent variable
For y = f(x), find all x such that:
sum of y is > p where p is a positive integer
sum of y is the minimum of all sums that are greater than p

I am looking to find some mathematical way to determine a relative rating among users.
For example, ( A1:5 = completion of task A1, taking 5 seconds)
Bob : A1:5 A2:6 A3:15
Joe : A1:5 A2:10 A3:15
What I am looking to come up with is a numeric rating of who is better at the "A" task based on how fast they complete each task. ( the shorter the time, the better )
So in the above example, Bob, would have a higher rating, and this is pretty easy to figure out.
However, when more, and unequal completion of the tasks are added... it starts to get complex:
Bob : A1:3 A2:9 A3:12 B1:20 B2:10 B3:1 D1:15 D2:20
Joe : A1:5 A2:11 A3:13 B1:15 B2:12 B3:2 C1:4
Is there a mathematical model that describes what I am trying to achieve?

Probably, but we'd need to know what you're trying to achieve first!
With your first example, it looks like you're summing the time for all the tasks, and ranking the users based on the total. Would that work for your second example?
Are you ranking each user on each task, summing the ranks, and then ranking the users on that total?
Try to talk exactly through what you want to do step-by-step. If the answer doesn't jump out at you, write down the steps and post them here.

So what I am trying to achieve is this:
A bunch of users perform N number of tasks. Each task can have 1-M sub tasks. eg:
Task[ 0 ] : Sub tasks = 2
Task[ 1 ] : sub tasks = 3
User A
Task[0][0] = 20
Task[0][1] = 35
Task[1][0] = 45
Task[1][1] = 42
Task[1][2] = 56
User B
Task[0][0] = 15
Task[0][1] = 26
Task[1][0] = 49
Task[1][1] = 22
Task[1][2] = 39

OK, but how are you wanting to rank the users?
Are you just summing the total time for all sub-tasks of all tasks and ranking based on that?
Are you summing the time for the sub-tasks of each task, ranking the users per task, summing the ranks for all tasks, and then ranking the users based on that?
You need to explain how you want to get from a series of tasks, sub-tasks and times to a rank for the user.

I've recently been having doubts about the way I've been approaching certain aspects of OO design in my projects (C#), and am looking for some advice. I use Castle Windsor IoC/DI framework, where dependencies are injected via class constructors. I also use a mocking framework (Moq) for my unit tests.
To support both frameworks I tend to find myself doing one of two things:
- creating an interface for every class, even if it's internal, or unlikely to have more than one concrete implementation (such as helper classes)
- or, I'll make such a class "mockable", which requires giving it a parameterless constructor, and marking its members as "virtual".
Both of these approaches feel like I'm writing additional code just to satisfy these two frameworks (particularly unit testing), but it does mean I can test a class in isolation, without it calling into potentially complex helper class functionality (which is the whole point of a unit test isn't it?).
My projects are typically self-contained desktop applications with no public API. Some articles I've read suggest that I should therefore not be using things like DI and interfaces, and I shouldn't even be unit testing internal classes. If I followed the latter advice then none of my code would be covered! (If you're wondering, I'm able to unit test internal classes because I use the "InternalsVisibleTo" attribute in my assemblies).
I'm now wondering if I'm taking the "separation of concerns" aspect of OO too far? Am I right to be using dependency injection with internal classes that will only ever have one concrete implementation (e.g. a "helper" class)? Or should I ditch DI and just instantiate such dependent classes? The latter would of course create a strong-coupling, making unit testing more difficult, especially if that helper class contained complex functionality, did database work, etc.
I hope I've made my concerns clear. To summarise, I guess I would like to know if I'm not using DI for its intended purpose, and whether my approach to unit testing and mocking is correct.

I'd guess that any meaningful answer has to be based on the reasons you are using the techniques. Interfaces and a framework in a team environment and managed in a central way can be, as I found, a very good way of managing the code people write and also a extremely useful mechanism that enables the interaction of code written in different languages and by different teams. The ability to have another person write a test based on an interface is also very useful.
If you're working by yourself some of the benefits interfaces can bring as just mentioned might be regarded as wasted coding time but perhaps bring benefits that are worth the extra code at design and debug time and also in introducing some discipline. However if you're writing code that you expect others to have to work with in the future you're probably contributing to their being able to understand it relatively quickly - though are probably demanding a fair level of expertise from those future people by your selection of framework etc.
Also if your code is part of a generic platform used across applications then using interfaces etc. probably contributes to that. However if its for a specific instance then as you suggest you may be adding generality that's not required.
From another perspective i.e. yours, rather than 'the company' are you learning skills and methods that improve your standards - it can get very boring doing the simple things without new approaches.
I suppose you've got to way the pros and cons on each technique from say a client, company(over say a N year period) and personal perspective to reach a real conclusion.

Does anyone know about what tools and technologies are used to develop CodeProject? I am also interested in the hardware configuration. I tried to search for it, but couldn't find any information on it. I would appreciate it if anyone can share that information

No, I meant my answer is incomplete one. I just gathered possible things to answer your question.

Oh, I am sorry. I understood it differently. Thank you for your articles, I am reading them at the moment. They seem to have alot on ASP.NET side of the website, very informative.

Over the years I seem to go back and forth over what I prefer regarding multiple method names vs a single method with a discrimination parameter.
Sometimes I prefer multiple, similar methods:
LogError(sometext)
LogWarning(sometext)
And other times I see it more as a single method with an enumerated parameter:
Log(type, sometext)
It seems pretty subjective as to what conveys intent best and makes using the class easier.
Any opinions? (Particularly interested in thoughts that contain an objective reason. I already have subjective thoughts that keep varying over time.  )
Thanks.
