     The basic rule is: A project results in a single output file [1].

     If you want to package building blocks into static libraries, create a project for each one.

     Unit test are separate from the code, so it's common to see a "foo" and a "foo test" project side by side.

     With respect to your small building blocks, I use this guideline: If it is closely enough related to be put in the same folder, it is closely enough related to be put in the same project.

     And managing a ton of small projects is incredibly frustrating. They each have a million settings and definitions (under multiple configurations and platforms...) that are a real pain to transfer from one project to the other.

     Property pages are intended to solve this problem. Just define a property page containing related settings and definitions, and it becomes as easy as adding the property page to a new project.

     As each project can pull its settings from multiple property pages, you can group them into logical groups. As an example: a "unit test" property page with all settings related to your unit test framework.

     To create property page in Visual Studio 2015: in the View menu, there is an option "Property Manager". You get a different tree view of your solution, with the projects, then the configurations, and then all the property pages for that project+configuration combination. The context menu for the configuration has an option to create a new property page or to add an existing one.

     [1] Although it is common to have the Release configuration result in foo.dll and Debug configuration in food.dll, so they can exist next to each other without resorting to the Debug/ and Release/ folders. In the General properties, set the TargetName to "$(ProjectName)d" (for Debug configuration) and remove the "$(Configuration)" from the OutputDirectory (for all configurations) to achieve this.

   • What are the principles behind, and benefits of, the "party model"?

     Top Answer

     Answered Apr 04, 2009 · 25 votes

     • What are the core principles and motivating forces behind the party model?

     To the extent that I've used it, it's mostly about code reuse and flexibility. We've used it before in the guest / user / admin model and it certainly proves its value when you need to move a user from one group to another. Extend this to having organizations and companies represented with users under them, and it's really providing a form of abstraction that isn't particularly inherent in SQL.

     • What does it prescribe you do to your data model? (My bit above is pretty high level and quite possibly incorrect in some ways. I've been on a project that used it, but I was working with a separate team focused on other issues).

     You're pretty correct in your bit above, though it needs some more detail. You can imagine a situation where an entity in the database (call it a Party) contracts out to another Party, which may in turn subcontract work out. A party might be an Employee, a Contractor, or a Company, all subclasses of Party. From my understanding, you would have a Party table and then more specific tables for each subclass, which could then be further subclassed (Party -> Person -> Contractor).

     • What has your experience led you to feel about it? Did you use it, and if so, would you do so again? What were the pros and cons?

     It has its benefits if you need flexibly to add new types to your system and create relationships between types that you didn't expect at the beginning and architect in (users moving to a new level, companies hiring other companies, etc). It also gives you the benefit of running a single query and retrieving data for multiple types of parties (Companies,Employees,Contractors). On the flip side, you're adding additional layers of abstraction to get to the data you actually need and are increasing load (or at least the number of joins) on the database when you're querying for a specific type. If your abstraction goes too far, you'll likely need to run multiple queries to retrieve the data as the complexity would start to become detrimental to readability and database load.

     • Did the party model limit your choice of ORMs? For example, did you have to eliminate certain ORMs because they didn't allow for enough of an "abstraction layer" between your domain objects and your physical data model?

     This is an area that I'm admittedly a bit weak in, but I've found that using views and mirrored abstraction in the application layer haven't made this too much of a problem. The real problem for me has always been a "where is piece of data X living" when I want to read the data source directly (it's not always intuitive for new developers on the system either).

   • What are the specifics of the definition of a string in C?

     Top Answer

     Answered Feb 22, 2020 · 8 votes

     c1 is mostly [1] equivalent to &c1[0], which is holding one string, "CS".

     There's a second string lurking in there, "324", starting at &c1[3] -- but as long as you access c1 as c1, the string "CS" is all the functions strcpy() et al. would see.

     [1]: c1 is an array, &c1[0] is a pointer.

   • What are some of the core principles needed to master multi-threading using Delphi?

     Top Answer

     Answered May 23, 2018 · 20 votes

     Short answer Go to OmnyThreadLibrary install it and read everything on the site.

     Longer answer You asked for some info so here goes: Here's some stuff to read:

     http://delphi.about.com/od/kbthread/Threading_in_Delphi.htm I personally like: Multithreading - The Delphi Way. (It's old, but the basics still apply)

     Basic principles: Your basic VCL application is single threaded. The VCL was not build with multi-threading in mind, rather thread-support is bolted on so that most VCL components are not thread-safe. The way in which this is done is by making the CPU wait, so if you want a fast application be careful when and how to communicate with the VCL.

     Communicating with the VCL Your basic thread is a decendent of TThread with its own members. These are per thread variables. As long as you use these you don't have any problems. My favorite way of communicating with the main window is by using custom windows Messages and postmessage to communicate asynchronically. If you want to communicate synchronically you will need to use a critical section or a synchonize method. See this article for example: http://edn.embarcadero.com/article/22411

     Communicating between threads This is where things get tricky, because you can run into all sorts of hard to debug synchonization issues. My advice: use OmnithreadLibrary, also see this question: Cross thread communication in Delphi Some people will tell you that reading and writing integers is atomic on x86, but this is not 100% true, so don't use those in a naive way, because you'll most likely get subtle issues wrong and end up with hard to debug code.

     Starting and stopping threads In old Delphi versions Thread.suspend and Thread.resume were used, however these are no longer recommended and should be avoided (in the context of thread synchronization). See this question: With what delphi Code should I replace my calls to deprecated TThread method Suspend? Also have a look at this question although the answers are more vague: TThread.resume is deprecated in Delphi-2010 what should be used in place? You can use suspend and resume to pause and restart threads, just don't use them for thread synchronization.

     Performance issues Putting wait_for... , synchonize etc code in your thread effectively stops your thread until the action it's waiting for has occured. In my opinion this defeats a big purpose of threads: speed So if you want to be fast you'll have to get creative.

     A long time ago I wrote an application called Life32. Its a display program for conways game of life. That can generate patterns very fast (millions of generations per second on small patterns). It used a separate thread for calculation and a separate thread for display. Displaying is a very slow operation that does not need to be done every generation. The generation thread included display code that removes stuff from the display (when in view) and the display thread simply sets a boolean that tells the generation thread to also display the added stuff. The generation code writes directly to the video memory using DirectX, no VCL or Windows calls required and no synchronization of any kind. If you move the main window the application will keep on displaying on the old location until you pause the generation, thereby stopping the generation thread, at which point it's safe to update the thread variables. If the threads are not 100% synchronized the display happens a generation too late, no big deal. It also features a custom memory manager that avoids the thread-safe slowness that's in the standard memory manager. By avoiding any and all forms of thread synchronization I was able to eliminate the overhead from 90%+ (on smallish patterns) to 0.

   • What are the pros and cons of using the two different programming styles of CGI.pm with Perl?

     Top Answer

     Answered Jan 19, 2010 · 17 votes

     Behind the scenes, CGI.pm is doing the same thing despite the styles. The functional interface actually uses a secret object that you don't see.

     For many small-scale CGI projects, you're probably never going to need more than one CGI object at a time, so the functional interface is fine. This might be the more common style, but only because most people make small scripts for very specific tasks. If you have a lot of other stuff going on, you might not like CGI.pm importing a long list (and it is long) of function names into your script. Some of the function names might clash with those other modules want to import.

     I, however, always use the object-oriented interface. I don't have to worry about name collisions, and it's apparent where any method came from since you see its object. It's also easy to pass the object as arguments to other parts of large applications, etc.

     Some people might complain about the extra typing, but that's never been the slow part of programming for me. I've been doing Perl for a long time and I don't mind the syntax. However, I only use CGI to get the input and maybe send the output. I don't mess with any of the HTML stuff.

     When it talks about one CGI.pm object at a time, it's referring to access to the input. Once you've read STDIN, for instance, another CGI.pm object won't be able to read that. You can have as many objects as you like though. They just won't share data and the first one gets all of POST data.

     You can actually use a mixture though. You can import some things, like :html, but still use the OO interface to deal with the input.

   2 days ago · Functions in Programming is a block of code that encapsulates a specific task or related group of tasks. Functions are defined by a name, may have parameters and may return a value. The main idea behind functions is to take a large program, break it into smaller, more manageable pieces (or functions), each of which accomplishes a specific task.
