  • How do you go from an abstract project description to actual code?

    - by Jason
    Maybe its because I've been coding around two semesters now, but the major stumbling block that I'm having at this point is converting the professor's project description and requirements to actual code. Since I'm currently in Algorithms 101, I basically do a bottom-up process, starting with a blank whiteboard and draw out the object and method interactions, then translate that into classes and code. But now the prof has tossed interfaces and abstract classes into the mix. Intellectually, I can recognize how they work, but am stubbing my toes figuring out how to use these new tools with the current project (simulating a web server). In my professors own words, mapping the abstract description to Java code is the real trick. So what steps are best used to go from English (or whatever your language is) to computer code? How do you decide where and when to create an interface, or use an abstract class?

  • Does Amazon S3's HTTP Uploads feature support web-hook style callbacks?

    - by Gabe Hollombe
    When uploading files to Amazon S3 using the browser http upload feature, I know I can specify a success_action_redirect field/value that will tell my browser where to go when the upload is done. I'm wondering: is it possible to ask Amazon to make a web hook style POST request to my web server whenever a file gets uploaded? Basically, I want a way of being notified whenever a client uploads a new file, so that my server can process the upload. I'd like to do this without relying on the client to make the request to my server to tell me the file has been uploaded (never trust the client, right?).

  • Design pattern for Fat Client - Thin Client to use Common code?

    - by kurozakura
    Windows-based client application and web-client application(consuming the same code which windows-client uses) what is the preferable pattern for this scenario? Is it ok to have the code in the common place where both the projects and refer it as dll i.e one which is a windows app and other which is going consume the same code which windows client will be exposing.

  • Code understanding, reverse engineering, best concepts and tools. Java.

    - by core07
    One of most demanding tasks for any programmer, architect is understanding other's code. E.g. I am contractor, hired to rescue some project very quickly. Fix bugs, plan global refactoring and therefore I need most efficient way to understand the code. What is the list of concepts, their priority and best tools for this? Of what I know: reverse code engineering to create object models (creating of diagram per package is not so convenient), create sequence diagrams (the tool connects in debug mode to the system and generates diagrams from runtime). Some visualizing techniques, using some tools to work not just with .java but also with e.g. JPA implementors like Hibernate. Generate diagram for not all the codebase, but add some class and then classes used by it. Is Sparx Enterprise Architect state of the art in reverse engineering or far from that. Any other better tools? Ideally would be that tool makes me understand the code as if I wrote it myself :)

  • Java: Best practices for turning foreign horror-code into clean API...?

    - by java.is.for.desktop
    Hello, everyone! I have a project (related to graph algorithms). It is written by someone else. The code is horrible: public fields, no getters/setters huge methods, all public some classes have over 20 fields some classes have over 5 constructors (which are also huge) some of those constructors just left many fields null (so I can't make some fields final, because then every second constructor signals errors) methods and classes rely on each other in both directions I have to rewrite this into a clean and understandable API. Problem is: I myself don't understand anything in this code. Please give me hints on analyzing and understanding such code. I was thinking, perhaps, there are tools which perform static code analysis and give me call graphs and things like this.

  • How can I dynamically inject code to event handlers in Delphi?

    - by mjustin
    For debugging / performance tests I would like to dynamically add logging code to all event handlers of components of a given type. For example, for all Dataset components located ona TDatamodule, I would like to add some code for the BeforeOpen and the AfterOpen event to store the start and end time and send a line to a logger with the elapsed time in the AfterOpen event. I would prefer to do this dynamically (no component subclassing), so that I can add this to all existing datamodules and forms with minimal effort only when needed. Iterating all components and filtering by their type is easy, but for the components which already have event handlers assigned, I need a way to store the existing event handlers, and assign a new modified event handler which first does the logging and then will invoke the original code which was already present. Is there a design pattern which can be applied, or even some example code which shows how to implement this in Delphi?

  • WPF -- Where do you draw the line between code and XAML?

    - by John Franks
    I'm a long-time C#/.NET programmer but totally new to WPF and the System.Windows.Controls namespace and XAML. The more I learn about it the more I realize that you can do pretty much all of your GUI initialization and event handling glue in either XAML or in code (say C# code or VB.Net code). My question is to those who have been working on WPF for longer and ideally those who have shipped apps with it -- where did you find was the best place to 'draw the line' between XAML and code? Did you use XAML wherever you could? Only where interfacing with non-coding UI designers? Any tips in this area would be extremely helpful to myself and other coders who are just getting into WPF programming and are kind of paralyzed by all the choices we can make!

  • Explain this C# code: byte* p = (byte*) (void*) Scan0;

    - by qulzam
    I found the code from the net in which i cant understand this line:- byte* p = (byte*)(void*)Scan0; There Scan0 is System.IntPtr. It is code of C#.Net. Plz Explain the above line. The complete code is given below. this is code to convert a image in grayscale. public static Image GrayScale(Bitmap b) { BitmapData bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb); int stride = bmData.Stride; System.IntPtr Scan0 = bmData.Scan0; unsafe { byte* p = (byte*)(void*)Scan0; int nOffset = stride - b.Width * 3; byte red, green, blue; for (int y = 0; y < b.Height; ++y) { for (int x = 0; x < b.Width; ++x) { blue = p[0]; green = p[1]; red = p[2]; p[0] = p[1] = p[2] = (byte)(.299 * red + .587 * green + .114 * blue); p += 3; } p += nOffset; } } b.UnlockBits(bmData); return (Image)b; } I understand all the code but only have the problem on this line. byte* p = (byte*)(void*)Scan0;

  • How to debug a WCF Service with an HTTP Context?

    - by JL
    I need to debug a WCF service but it needs to have an HTTP Context. Currently I have a solution with a WCF service web site, when I click on debug it starts up and then fires up an html page that contains no test form. While the project is running I tried starting the wcftestclient manually, then provided the address of my service, it finds the service but when I invoke it, it bypasses the IIS layer (or development server), so the httpContext is null... What is the correct way to debug a WCF service through an IIS context?

  • How do I temporarily monkey with a global module constant?

    - by Daniel
    Greetings, I want to tinker with the global memcache object, and I found the following problems. Cache is a constant Cache is a module I only want to modify the behavior of Cache globally for a small section of code for a possible major performance gain. Since Cache is a module, I can't re-assign it, or encapsulate it. I Would Like To Do This: Deep in a controller method... code code code... old_cache = Cache Cache = MyCache.new code code code... Cache = old_cache code code code... However, since Cache is a constant I'm forbidden to change it. Threading is not an issue at the moment. :) Would it be "good manners" for me to just alias_method the special code I need just for a small section of code and then later unalias it again? That doesn't pass the smell test IMHO. Does anyone have any ideas? TIA, -daniel

  • how can multiple trailing slashes can be removed from an url in Ruby

    - by splintercell
    Hello, What i'm trying to achieve here is lets say we have two example urls: url1 "http://emy.dod.com/kaskaa/dkaiad/amaa//////////" & url2 = "http://www.example.com/". How can I extract the striped down urls? url1 : "http://emy.dod.com/kaskaa/dkaiad/amaa" & url2 to "http://http://www.example.com"? URI.parse in ruby sanitizes certain type of malformed url but is ineffective in this case. If we use regex then /^(.*)\/$/ removes a single slash (/) from url1 & is ineffective for url2. Is anybody aware of how to handle this type of url parsing? The point here is I dont want my system to have "http://www.example.com/" & "http://www.example.com" being treated as two different urls. And same goes for "http://emy.dod.com/kaskaa/dkaiad/amaa////" & "http://emy.dod.com/kaskaa/dkaiad/amaa/" cheers, -dg

  • Is Odersky serious with "bills !*&^%~ code!" ?

    - by stacker
    In his book programming in scala (Chapter 5 Section 5.9 Pg 93) Odersky mentioned this expression "bills !*&^%~ code! In the footnote on same page: "By now you should be able to figure out that given this code,the Scala compiler would invoke (bills.!*&^%~(code)).!()." That's a bit to cryptic for me, could someone explain what's going on here?

  • REST - why we need million urls and different HTTP request?

    - by Andre
    I asked this question. But I still don't understand why we need to utilize different HTTP requests: DELETE/PUT/POST/GET in order to build nice API Wouldn't it be a lot simpler to pass all information in request parameters and have a SINGLE ENTRY-POINT for your api?: GET www.example.com/api?id=1&method=delete&returnformat=JSON GET www.example.com/api?id=1&method=delete&returnformat=XML or POST www.example.com/api {post data: id=1&method=delete&returnformat=JSON} POST www.example.com/api {post data: id=1&method=delete&returnformat=XML} and then - we can handle all methods and data internally without the need for hundreds of urls... how would you call this type of API - It's not REST apparently, it's not SOAP. then - what is it? UPDATE I'm not proposing any new standards here. I merely asking a question in order to better understand why web services work the way they work.

  • Passing URIs as URL arguments in Drupal

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • What are the pro and cons of having localization files vs hard coded variables in source code?

    - by corgrath
    Definitions: Files: Having the localization phrases stored in a physical file that gets read at application start-up and the phrases are stored in the memory to be accessed via util-methods. The phrases are stored in key-value format. One file per language. Variables: The localization texts are stored as hard code variables in the application's source code. The variables are complex data types and depending on the current language, the appropriate phrase is returned. Background: The application is a Java Servlet and the developers use Eclipse as their primary IDE. Some brief pro and cons: Since Eclipse is use, tracking and finding unused localizations are easier when they are saved as variables, compared to having them in a file. However the application's source code becomes bigger and bloated. What are the pro and cons of having localization text in files versus hard coded varibles in source code? What do you do and why?

  • Where can I find a library that parses source code and is able to extract the scope of where your cursor is currently in the code?

    - by Anthony
    In SublimeText(2), when you press [ctrl + shift + p] (mac osx) you are shown a scope of where your caret/cursor is in the source code at the given moment e.g.: entity.name.tag.inline.any.html meta.tag.inline.any.html text.html.basic I am curious about what library or script is used to parse the document/file and create that scope string. A sidenote: Typing view.syntax_name(view.sel()[0].b) into Sublime's console will output the scope as well.
