I figured maybe something of different challenge levels. I could only go as far as calculus or linear algebra. Any partial differential equations questions would get me :->

Try Sudoku or logic puzzles. Those may make for an interesting challenge.

Yep, they are a lot of fun. I got a Kakuro[^] puzzle book for Christmas and it's pretty addictive

Played that once. Make's Sudoku look like child's play. There's an interesting Sudoku[^] client here that you can try. Check the messages for the executable.

I'll look at it closer later today. Looks really cool

I don't use it to ask or answer questions but to post interesting math articles I've read. Would be nice if others started doing that too.

I'll try to make more effort to help you add to the interesting articles part

By all means.

Saw this in the email reply and I wondered how I pissed you off.

You didn't piss me off. It is a sig from one post by Jeremy Falcon...It is getting old, so back to my one favorite Star Wars quote

I figured that out when I saw the message, but the email does't use HTML so I wasn't sure until I opened it.

Good idea. I know it's sad, but I do get off a bit on really good maths sites/texts. I often toyed with the idea of posting things about different (common) algorithms.

Do you use design patterns?
I used Composite and Singleton, occasionally.

When developing systems nowadays, it is very difficult to develop a system that doesn't have some forms of pattern applied to it. Developing applications is about good design and in the design process, you will discover what patterns apply.

Focus your design effort on the highest level business logic and unique requirements.
'Patterns' are a trap.
Specifically, if you have some message coming in on your port,
Your design will consist of a description of that message, and the action taken.
Whether your code 'Polls' or uses 'Events' is irrelevant to this design.
At one layer or another we are ALWAYS polling:
These are your options:
Write code that 'polls'.
Use a library that polls on another thread and raises an event to your code.
Use a library that uses lower level hardware that polls at an embedded level.
Use a library, that uses hardware, that uses a chip that raises an interrupt as a result of the microprocessor 'polling' pins very quickly.
If your highest level design is agnostic of 'design' patterns, then it is done right.
It can be implemented successfully by any combination of language, or 'pattern'

Two things.
Why are you replying on a very old comment?
What relevance does polling have to do with the comment?

Yes, and I used Singleton to restrict the number of connections to the database. After getting benefit from this, now I'm looking for other patterns too, so, recently started studying design patterns -- though its not regular. But during study, noted that self studying design patterns is a bit challenging to understand.
How you covered (are covering) design patterns?
Regards.

Like you I'm self studying design patterns (I've the book of Gamma, Helm, Johnson, Vlissides) and, like you, I find them quite challenging. I think that if you need one pattern in you project, then you'll have a chance to deeply understand it.

Thanks for the book (Design Patterns: Elements of Reusable Object-Oriented Software) reference.

True. But before using patterns we must have know how about it.

True, of course. But the book we wrote about is of big help, because it first identifies and clarifies the problem the pattern addresses, then explains the details of the pattern itself.

Hi,
I was wondering if there are some guidelines regarding the following issue in the .NET framework:
Polling based design (the client polls the server every X interval for changes) Vs. Events driven design (the client registers to the event and the server will raise the event)?
i am not sure when to use each of the above...
|
|
|
|

There is an alternative: Observers. Polling requires significant effort to keep state in sync so that you can keep track of changes. Events are good, but do require that items subscribe to the events to keep track of them.
