  • A free Step by Step guide to learning Sparx Enterprise Architect

    - by Yogi Yang 007
    I have just downloaded Sparx Enterprise Architect 7.5 but unfortunately I am not able to find a getting started guide or something like that. I have gone through official site of Sparx but there is not step by step guide to learning Sparx EA. I want a guide that will implement a small project and give instructions step by step so that I can understand and try out Sparx EA. I did find a few sites selling step by step guides but at this point of time I do not want to spend money on them.

  • Are there any "undocumented features" in Silverlight?

    - by Sorskoot
    I was wondering if there are any features in Silverlight 2 or 3 that aren't documented or are hidden very deep in the framework? Stuff that can be very helpful in some cases, but can be a pain to find. Are there any "hidden" gems? I'm thinking about stuff you normaly don't find in tutorials and in demos. For example, finding information about the operating system the Silverlight Application is running on thru the System.OperatingSystem class.

  • How to assert on number of html table rows in ruby using capybara + cucumber

    - by Neil
    I am trying to get to grips with BDD web development in Ruby using cucumber + capybara and I am stuck at what should be an easy task - just to check the number of rows in a table. Something along the lines of: page.should have_xpath("//table[@id='myTable']") find("//table[@id='myTable']/tr").length.should = 3 But this doesn't work and I can't find a way to assert against the table length. Any ideas anyone (please be easy on me tho' I'm a ruby nooby) Thanks in advance Neil

  • Runtime C function details

    - by Sridhar
    Hi, Is there any way to find particular C language function's input and output parameters from a framework (apple's ARM) during the runtime or from any method with out knowing the headers. It is a framework and there are no header files for it.I decompile it with IDA Pro and it gives me the function names but not input and output parameters information. I am able to load those private functions using dlsym. Is it possible to find the parameters info in runtime (C language or Objective C) or from IDA Pro ? Regards, Raghu

  • Why use ASP.NET MVC 2 for REST services? Why not WCF?

    - by Jeremy McGee
    So I see that MVC 2 now supports [HttpPut] and [HttpDelete] as well as [HttpGet] and [HttpPost], making it possible to do a full RESTful Web service using it. I've been using the REST toolkit for WCF for a while and find it fairly powerful, but I'd be interested to find out what (if any) advantages there are using the MVC 2 approach. Links, war stories, or even pure hear-say are welcome.

  • Why is it still so hard to write software?

    - by nornagon
    Writing software, I find, is composed of two parts: the Idea, and the Implementation. The Idea is about thinking: "I have this problem; how do I solve it?" and further, "how do I solve it elegantly?" The answers to these questions are obtainable by thinking about algorithms and architecture. The ideas come partially through analysis and partially through insight and intuition. The Idea is usually the easy part. You talk to your friends and co-workers and you nut it out in a meeting or over coffee. It takes an hour or two, plus revisions as you implement and find new problems. The Implementation phase of software development is so difficult that we joke about it. "Oh," we say, "the rest is a Simple Matter of Code." Because it should be simple, but it never is. We used to write our code on punch cards, and that was hard: mistakes were very difficult to spot, so we had to spend extra effort making sure every line was perfect. Then we had serial terminals: we could see all our code at once, search through it, organise it hierarchically and create things abstracted from raw machine code. First we had assemblers, one level up from machine code. Mnemonics freed us from remembering the machine code. Then we had compilers, which freed us from remembering the instructions. We had virtual machines, which let us step away from machine-specific details. And now we have advanced tools like Eclipse and Xcode that perform analysis on our code to help us write code faster and avoid common pitfalls. But writing code is still hard. Writing code is about understanding large, complex systems, and tools we have today simply don't go very far to help us with that. When I click "find all references" in Eclipse, I get a list of them at the bottom of the window. I click on one, and I'm torn away from what I was looking at, forced to context switch. Java architecture is usually several levels deep, so I have to switch and switch and switch until I find what I'm really looking for -- by which time I've forgotten where I came from. And I do that all day until I've understood a system. It's taxing mentally, and Eclipse doesn't do much that couldn't be done in 1985 with grep, except eat hundreds of megs of RAM. Writing code has barely changed since we were staring at amber on black. We have the theoretical groundwork for much more advanced tools, tools that actually work to help us comprehend and extend the complex systems we work with every day. So why is writing code still so hard?
