  • Tab versus space indentation in C#

    - by Lars Fastrup
    I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

  • Webfaction apache + mod_wsgi + django configuration issue

    - by Dmitry Guyvoronsky
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?

  • what is middleware exactly?

    - by michel
    I hear a lot of people talking last days about middleware, but what is the exact definition of middleware. If I look in information about middleware I found a lot of information and some definitions, but while reading this information and defintions it seems that mostly all 'wares' are in the middle of something. So from my opinion all things are middleware? or do you have an example of a ware that doesn't is middleware?

  • Good practice to create extension methods that apply to System.Object?

    - by Christian
    Hello, I'm wondering whether I should create extension methods that apply on the object level or whether they should be located at a lower point in the class hierarchy. What I mean is something along the lines of: public static string SafeToString(this Object o) { if (o == null || o is System.DBNull) return ""; else { if (o is string) return (string)o; else return ""; } } public static int SafeToInt(this Object o) { if (o == null || o is System.DBNull) return 0; else { if (o.IsNumeric()) return Convert.ToInt32(o); else return 0; } } //same for double.. etc I wrote those methods since I have to deal a lot with database data (From the OleDbDataReader) that can be null (shouldn't, though) since the underlying database is unfortunately very liberal with columns that may be null. And to make my life a little easier, I came up with those extension methods. What I'd like to know is whether this is good style, acceptable style or bad style. I kinda have my worries about it since it kinda "pollutes" the Object-class. Thank you in advance & Best Regards :) Christian P.S. I didn't tag it as "subjective" intentionally.

  • java api design - NULL or Exception

    - by srini.venigalla
    Is it better to return a null value or throw an exception from an API method? Returning a null requires ugly null checks all over, and cause a major quality problem if the return is not checked. Throwing an exception forces the user to code for the faulty condition, but since Java exceptions bubble up and force the caller code to handle them, in general, using custom exceptions may be a bad idea (specifically in java). Any sound and practical advice?

  • Node & Redis: Crucial Design Issues in Production Mode

    - by Ali
    This question is a hybrid one, being both technical and system design related. I'm developing the backend of an application that will handle approx. 4K request per second. We are using Node.js being super fast and in terms of our database struction we are using MongoDB, with Redis being a layer between Node and MongoDB handling volatile operations. I'm quite stressed because we are expecting concurrent requests that we need to handle carefully and we are quite close to launch. However I do not believe I've applied the correct approach on redis. I have a class Student, and they constantly change stages(such as 'active', 'doing homework','in lesson' etc. Thus I created a Redis DB for each state. (1 for being 'active', 2 for being 'doing homework'). Above I have the structure of the 'active' students table; xa5p - JSON stringified object #1 pQrW - JSON stringified object #2 active_student_table - {{studentId:'xa5p'}, {studentId:'pQrW'}} Since there is no 'select all keys method' in Redis, I've been suggested to use a set such that when I run command 'smembers' I receive the keys and later on do 'get' for each id in order to find a specific user (lets say that age older than 15). I've been also suggested that in fact I used never use keys in production mode. My question is, no matter how 'conceptual' it is, what specific things I should avoid doing in Node & Redis in production stage?. Are they any issues related to my design? Students must be objects and I sure can list them in a list but I haven't done yet. Is it that crucial in production stage?

  • using KVO to filter an NSTableView using NSPredicate (with arrays)

    - by KingRufus
    My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name

  • 'AND' vs '&&' as operator

    - by ts
    Actually, i am facing a codebase where developpers decided to use 'AND' and 'OR' instead of '&&' and '||'. I know that there is difference in operators precedence (&& goes before 'and'), but with given framework (prestashop to be precise) is clearly not a reason. So, my question: which version are you using? Is 'and' more readable than '&&'? || there is ~ difference?

  • Placement of service methods

    - by mhp
    Let's assume I have two service classes with the following methods: GroupService createGroup() deleteGroup() updateGroup() findGroup() UserService createUser() deleteUser() updateUser() findUser() Now, I am thinking about the aesthetics of theses classes. Imagine we want to implement a method which search for all user of a specific group. Which service class is responsible for such a method? I mean, the return value is a user (or maybe a collection of users) but the parameter (which means the name of the group) is a group. So which service class is the better place to put this method in?

  • Is there any appreciable difference between if and if-else?

    - by Drew
    Given the following code snippets, is there any appreciable difference? public boolean foo(int input) { if(input > 10) { doStuff(); return true; } if(input == 0) { doOtherStuff(); return true; } return false; } vs. public boolean foo(int input) { if(input > 10) { doStuff(); return true; } else if(input == 0) { doOtherStuff(); return true; } else { return false; } } Or would the single exit principle be better here with this piece of code... public boolean foo(int input) { boolean toBeReturned = false; if(input > 10) { doStuff(); toBeReturned = true; } else if(input == 0) { doOtherStuff(); toBeReturned = true; } return toBeReturned; } Is there any perceptible performance difference? Do you feel one is more or less maintainable/readable than the others?

  • What is the best way to use whitespace while programming?

    - by Emmanuel Smith
    I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques. I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is. I would like to know the same thing for commenting as well.

  • Python style: multiple-line conditions in IFs

    - by Eli Bendersky
    Hello, Sometimes I break long conditions in IFs to several lines. The most obvious way to do this is: if (cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Isn't very very appealing visually, because the action blends with the conditions. However, it is the natural way using correct Python indentation of 4 spaces. Edit: By the way, for the moment I'm using: if ( cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Not very pretty, I know :-) Can you recommend an alternative way ?

  • Where/When do C# and the .NET Framework fail to be the right tool?

    - by Nate Bross
    In my non-programming life, I always attempt to use the appropriate tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, PowerShell, batch files, and Java, as well as being versed in the web technologes (JavaScript, HTML, and CSS). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. I choose .NET and C# because I'm comfortable with it, but I'm looking for cases where it isn't appropriate.

  • CSS/HTML: Highlighting the "full width avaialble" to a list item

    - by JoshuaD
    I'm working on a website for a small law office. In the side-menu, I'm trying to highlight the "current page". I have tried changing the background of the LI, but this doesn't quite do the trick; the list item doesn't spread to the full width of the menu, so it looks bad. Here's a jfiddle. I would like the yellow section to highlight like the pink section is highlighted: filling up the full vertical and horizontal space, not just highlighting the text. Any suggestions on how to do this? I've included the style tag in the html just for example, obviously, and my real solution will be a little different when it's done. But I can't move forward until I figure out how to somehow highlight the entire line.

  • No production mode in Rails 3 Beta 3?

    - by ulf
    I wrote my first Rails 3 app and it ran absolutely fine in development mode. Now I deployed it on my server and wanted to start it in production mode. The app starts but none of my images or stylesheets are being loaded. The Rails console outputs a lot of RoutingErrors to those files. Isn't that mode available yet?

  • Django "Error: cannot import name escape" on windows

    - by Sam
    I cannot run the dev server because of this error ("Error: cannot import name escape"). I assume its because of modifications I've done to the project, but i have no idea how to find where the error is originating from to fix it. I don't import anything called escape anywhere. Update Using django-admin.py rather than the projects manage.py, don't know why... Update 2 Now manage.py is working. This may be because I had a file called email.py which was trying to import email.mime.text (ie trying to import itself) renaming to sendemail.py solved this problem.

  • Are there any reasons to make all fields and variables final?

    - by Roman
    In my current project I noticed that all class fields and variable inside methods are declared with final modifier whenever it's possible. Just like here: private final XMLStreamWriter _xmlStreamWriter; private final Marshaller _marshaller; private final OutputStream _documentStream; private final OutputStream _stylesStream; private final XMLStreamWriter _stylesStreamWriter; private final StyleMerger _styleMerger; public DocumentWriter(PhysicalPackage physicalPackage) throws IOException { final Package pkg = new Package(physicalPackage); final Part wordDocumentPart = pkg.createPart( "/word/document.xml", "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument"); // styles.xml final Pair<Part, String> wordStylesPart = wordDocumentPart.createRelatedPart(...); ... } Are there any reasons to do so? p.s. As I know project is not supposed to be multithreaded (at least I've heard nothing about it).

  • Naming member functions/methods with a single underscore, good style or bad?

    - by Extrakun
    In some languages where you cannot override the () operator, I have seen methods with a single underscore, usually for 'helper' classes. Something likes this: class D10 { public function _() { return rand(1,10); } } Is it better to have the function called Roll()? Is a underscore fine? After all, there is only one function, and it removes the need to look up the name of the class. Any thoughts?

  • Set Java Application's virtual machine max memory without access to VM parameters because of custom

    - by Tom
    I'm using a Java application which allows you to import custom files. On import, these files are loaded into memory. The problem is that the files I want to import are very big, this causes an OutOfMemory exception. The crash log also informs me that the VM was started with the java parameter "-Xmx512m", I want to alter this to "-Xmx1024m" so that I got double the memory available. The problem is that this application is using it's own JRE folder and that there's a launcher written in C which is calling the jvm.dll file. In any way, java.exe or javaw.exe are never called and thus I cannot set these parameters myself (if I delete these executables it doesn't matter, can still run the application - this is not the case with the dll). So, my question is, can I set this VM parameter in an other way? I'm even willing to alter the JRE files if there is no other way.

  • How to name variables wich are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non captialized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

  • Condition check inside a function or before its call?

    Which of these 2 programming styles do you prefer? Why? Are there particular advantages to one over the other? // Style 1 if (doBorder) doTheBorder(); if (doFrame) doTheFrame(); if (doDraw) doTheDraw(); void doTheBorder() { // ... } void doTheFrame() { // ... } void doTheDraw() { // ... } // Style 2 doTheBorder(); doTheFrame(); doTheDraw(); void doTheBorder() { if (!doBorder) return; // ... } void doTheFrame() { if (!doFrame) return; // ... } void doTheDraw() { if (!doDraw) return; // ... }
