• An exception to avoid copy and paste code?

  - by Jian Lin

  There are many files in our project that would call a Facebook api. And the call is complicated, spanning usually 8 lines or more, just for the argument values. In this case, we can make it into a function, and place that function in a common_library.php, but doing so would just change the name of the function call from the Facebook API function to our name, and we still need to repeat the 8 lines of arguments. Each time, the call is very similar, but with slight variations to the argument values. In that case, would copy and paste be needed no matter what we do?

• Searching for a source code editor component

  - by Iso5786

  Hi, I have to develop a program at work in which a consultant can enter a specification which is developed 2 years ago here in house. So i can't really tell what it is about. But the editor should support some standard functionality such as syntax highlighting, auto completion and maybe search & replace. I've searched for Java components but didn't find a good solution which matches my requirements. Anybody knows a good component? It doesn't matter in which language it is written but I prefer Java.

  - by fizzer

  Print all 12 verses of the popular holiday song.

Verse Two On the second day of Christmas my true love gave to me two turtle doves and a partridge in a pear tree. ... Verse N: On the nth day of Christmas my true love gave to me (Verse N-1 without the first line) (line added in verse N)

• Code igniter authentication code in controller security question

  - by Prime Studios

  I have a main controller to handle the very front-end of my authentication system, it handles login, logout, update user info, etc. functions that I anticipate calling by POST'ing from views/forms. What about something like a "delete_user" function though? My thoughts are a button in someones admin panel would say "Delete Account" and it would post to "/auth/delete", and the function would delete the user based on their session username or id. This seems a bit open ended, you could send out a link to someone and when they opened it while in that application it would delete their account.. Whats the best way to handle this?

• nginx multiple domain virtual host configuration

  - by Poe

  I'm setting up nginx with multiple domain or wildcard support for convenience sake, rather than setting up 50+ different sites-available/* files. Hopefully this is enough to show you what I'm trying to do. Some are static sites, some are dynamic with usually wordpress installed. If an index.php exists, everything works as expected. If a file is requested that does not exist (missing.html), a 500 error is given due to the rewrite. The logged error is: *112 rewrite or internal redirection cycle while processing "/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/missing.html" The basic nginx configuration I'm currently using is: ` listen 80 default; server _; ... location / { root /var/www/$host; if (-f $request_filename) { expires max; break; } # problem, what if index.php does not exist? if (!-e $request_filename) { rewrite ^/(.*)$ /index.php/$1 last; } } ... ` If an index.php does not exist, and the file also does not exist, I would like it to error 404. Currently, nginx does not support multiple condition if's or nested if so I need a workaround.

• Why does a Non-existant page returns 302 status when using a custom 404 page in asp.net

  - by webdevbytes

  I have setup custom 404 page custom404.aspx that returns a 404 Not Found error correctly, however the non-existant page that was initially requested returns a 302 Found status. So when I test thispagedoesnotexist.aspx, it returns a 302 Found then the custom404.aspx loads and returns a 404 Not Found status. I want to make sure that search spiders/bots understand that the requested page does not exist and should not show up in any search results. Is this the case? Cheers

• Library for parsing arguments GNU-style?

  - by Delan Azabani

  I've noticed the basic 'style' of most GNU core applications whereby arguments are: --longoption --longoption=value or --longoption value -abcdefg (multiple options) -iuwww-data (option i, u = www-data) They follow the above style. I want to avoid writing an argument parser if there's a library that does this using the above style. Is there one you know of?

• Is Webhooks a style/pattern or a specification?

  - by Emilio

  I've been reading about Webhooks and I'm trying to determine if it's a specification vs a style/pattern. By "specification" I mean that the implementation details, e.g. headers, payload and so on are well defined. By "style" or "pattern" I mean in the sense that REST is a style (as opposed to a spec) or a pattern which describes usage but doesn't define implementation details. From what I see, Webhooks is a style/pattern. That the event(s) which triggers the http callbacks are generated however the developer wants, and that the http callbacks have no specific implementation requirements except to be an http post. Is this correct?

• How to dynamically assigning style properties to element?

  - by poo

  function styling(elem, props) { for (var i in props) { if (i == "color") { elem.style.color = props[i].toString(); } if (i == "background") { elem.style.background = props[i].toString(); } } Using it: styling(links, { color: "blue", background: "yellow" }); I'm not really happy with the if-clauses and I want to dynamically add the style properties to the element, but I'm not sure how to do it. Someone out there would know how to do it? Solved it function styling(elem, props) { for (var i in props) { elem.style[i] = props[i].toString(); } } That seems to do the trick.

• C++ cast syntax styles

  - by palm3D

  A question related to Regular cast vs. static_cast vs. dynamic_cast: What cast syntax style do you prefer in C++? C-style cast syntax: (int)foo C++-style cast syntax: static_cast<int>(foo) constructor syntax: int(foo) They may not translate to exactly the same instructions (do they?) but their effect should be the same (right?). If you're just casting between the built-in numeric types, I find C++-style cast syntax too verbose. As a former Java coder I tend to use C-style cast syntax instead, but my local C++ guru insists on using constructor syntax. What do you think?

• Visual Studio - easy way to bring up type definition as source code

  - by Igor Zevaka

  Oftentimes I want to bring up a system class in a source view, so that I can browse the properties and methods exposed by the class in a source view. Below is the screenshot of what I mean: Usually I do this by selecting the class name and pressing F12 (or right clickGo To Definition). However, if I haven't got it anywhere ready, i have type it up and then do Go To Definition. Most of the time I have to delete what I typed later on. Is there a way to bring up this view without having to type the class name? The VS2010 Navigate To dialog doesn't support this.

• Defining a class with specific style dynamically in jQuery

  - by Acorn

  Is it possible to define a class with specific style attributes dynamically with jQuery, rather than setting the style of all elements with that class? I could set the attributes of the class at the end of the script once all the elements have been created, but is that the best way to go about it? If I define the style of the class with $('.class').css('property','value'); at the beginning of the script, nothing would happen because the elements with class .class haven't been created yet, right?

• machine learning and code generator from strings

  - by BCS

  The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.

• Save VM properties with EF code first

  - by Julien

  I thought this would be simple but can't find any good examples. public Class BookVm : ImplementsPropertyChanged { public int BookId {get;set;} private bool _favorite; public bool Favorite { get { return _favorite; } set { _favorite = value; OnPropertyChanged("Favorite"); MyDbContext.SaveChanges() // this does not work } } Then in my XAML bound to Book <CheckBox Content="Favorite" IsChecked="{Binding Favorite}" /> How and when do I call SaveChanges() on my DatabaseContext? I don't want to implement a save button. If I intercept the PropertyChange event and call SaveChanges, nothing seems to happen. My object is modified in memory but the database does not see a change. My BookVm class is created on application startup like so: foreach (var book in MyDbContext.Books) Books.Add(book); Where Books is an ObservableCollection<Book> in my MainWindowVm

• EF4 Code-First CTP5 Many-to-one

  - by Kevin McKelvin

  I've been trying to get EF4 CTP5 to play nice with an existing database, but struggling with some basic mapping issues. I have two model classes so far: public class Job { [Key, Column(Order = 0)] public int JobNumber { get; set; } [Key, Column(Order = 1)] public int VersionNumber { get; set; } public virtual User OwnedBy { get; set; } } and [Table("Usernames")] public class User { [Key] public string Username { get; set; } public string EmailAddress { get; set; } public bool IsAdministrator { get; set; } } And I have my DbContext class exposing those as IDbSet I can query my users, but as soon as I added the OwnedBy field to the Job class I began getting this error in all my tests for the Jobs: Invalid column name 'UserUsername'. I want this to behave like NHibernate's many-to-one, whereas I think EF4 is treating it as a complex type. How should this be done?

• Code Golf: Counting XML elements in file on Android

  - by CSharperWithJava

  Take a simple XML file formatted like this: <Lists> <List> <Note/> ... <Note/> </List> <List> <Note/> ... <Note/> </List> </Lists> Each node has some attributes that actually hold the data of the file. I need a very quick way to count the number of each type of element, (List and Note). Lists is simply the root and doesn't matter. I can do this with a simple string search or something similar, but I need to make this as fast as possible. Design Parameters: Must be in java (Android application). Must AVOID allocating memory as much as possible. Must return the total number of Note elements and the number of List elements in the file, regardless of location in file. Number of Lists will typically be small (1-4), and number of notes can potentially be very large (upwards of 1000, typically 100) per file. I look forward to your suggestions.

• Fast exchange of data between unmanaged code and managed code

  - by vizcaynot

  Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.
