Maybe a silly question this, but I'm a rookie developer. Lets say, in a data-driven CRM'ish application, I have a customer type that can go through a number of phases - i.e. phases 1 - 5. As a customer changes phase - events should trigger. Example - as a customer enters phase 3 from phase 2, an email is sent, some lists are updated an...
What are some good ways I can improve my system architecture design skills? I'm particularly interested in designs I can learn from... can anyone shoot out some examples of good design practice, lessons learned, things to guide me? ...
I have a problem, which I believe to be best solved through a functional style of programming. Coming from a very imperative background, I am used to program design involving class diagrams/descriptions, communication diagrams, state diagrams etc. These diagrams however, all imply, or are used to describe, the state of a system and the ...
After seeing the 13th Floor back in the day I have been obsessed to a degree with writing a simulator like that. I have written several simulations with a human base class that have a male and female subclass. They have a routine called runYear and they interact. They date, work, die, have kids, get sad, commit suicide, divorce, etc. ...
I'm designing a delegate method that is called when the remote server needs input from the delegate. The delegate at that point is responsible for filling in data to be sent to the server and also telling the server if there is an error at that point. The delegate method I have right now is: -(void)server:(MBServer*)server willSendDat...
I've been thinking about how to apply data versioning to a relatively simple database I have, and figured I should do something like is mentioned in Jim T's post where there are global revision #s (e.g. like in Subversion or Mercurial) and each database record has a validity interval. Example: Create a person. |Name|D.O.B |Tel...
I'm working on Java-based server software that needs to be customized for a few, but large customers. A separate instance of the server runs for each customer. Each customer has sufficiently differing requirements such that different business logics is required for each of the implementations. At this time, the different business logic...
Where can I find examples of very well produced enterprise-y software that have: Good, consistent use of keyboard shortcuts. Good keyboard form navigation Standarized form validation Standarized use of lookup/search screens. (User gets asked for Client ID, doesn't know it but can look it up from a popup window that returns it) Standari...
Could someone please explain when would I want to use delegation instead of inheritance? ...
When designing a server, we are considering two approaches: A asynchronous (select based) approach so the backend rpc can be parallelized in a single thread. A synchronous approach where each backend rpc is processed in another thread from the thread pool. There are trade offs: 1 has better performance and 2 has less code complexity...
Hi, I need to find some good tools for designing UI. I need only the design part, I don't need any code generation or anything like that... It would be nice to find some freeware ;) tia ...

How to go about creating a Hashmap in C from scratch ? What would be the parameters taken into consideration and what how would you test the hashmap as to how good it is ? As in what would be benchmark test cases which you require to run before you say that your hash map is complete. ...
As with many developers in small or mid sized shops, I have to put on my designer hat from time to time. I can't really justify buying something like CS4 or other designer tools. I do currently have a small tool bag of helpful, free tools like Paint.NET IconExtract ColorCop Are there any other good ones out there that I should chec...
I was given this really long flow chart (8 pages) of how we process our financial transactions. The most critical piece of our application. I'm sure you can imagine lots of squares and diamons with lines drawn all over the place, and then separate detail sheets describing which fields in the database to update, calculate, retrieve, store...
Currently I am on a team developing a new stand alone application in C#. The eventual goal is to roll this stand alone app into a previously developed larger application that pertains to the same processes. My question is this: I am looking for information on methodologies or processes that help with A) Design of said newer code, esspec...
This question is meant to apply to interfaces in general, but I'll use AS3/Flex for my language. It should be [mostly] obvious how to apply it in different languages. If I create a base class, and it extends an interface, there is an explicit contract defined: for every method in the interface, the base class must implement said method...
If you want to open a two-way connection between the browser and server, the only choice is to poll (hammer the server), or use comet (crufty and prone to disconnects). Why don't browsers just let you open up a plain TCP connection? Is there any practical benefit to not having this ability? ...
I keep hearing about the "Architect" title in larger software corporations, and am interested to know what they do and how they get it done. Is it their job to prepare visual diagrams outlining the functioning of the software? and what programs do they use to aid their design? Like Class Designing? Do they design at a higher level and ...
I'm building my first web application after many years of desktop application development (I'm using Django/Python but maybe this is a completely generic question, I'm not sure). So please beware - this may be an ultra-newbie question... One of my user processes involves heavy processing in the server (i.e. user inputs something, serv...
