• Starting a code library.

  - by Rob Stevenson-Leggett

  Hi, I've been meaning to start a library of reusable code snippets for a while and never seem to get round to it. I think my main problems are: Where to start. What structure should my library take? Should it be a compiled library (where appropriate or just classes I can drop into any project? Or a library project that can be included? In my experience, a built library will quickly become out of date and the source will get lost. So I'm leaning towards source libraries that I can export from SVN and include in any project. Intellectual property. I am employeed, so a lot of the code I write is not my IP. How can I ensure that I don't give my own IP away using it on projects in work and at home? I'm thinking the best way would be to licence my library with an open source licence and make sure I only add to it in my own time using my own equipment and therefore making sure that if I use it in a work project the same rules apply as if I was using a third party library. I write in many different languages and often would require two or more parts of this library. Should I look at implementing a few template projects and a core project for each of my chosen reusable components and languages? Has anyone else got this sort of library and how do you organise and update it?

• Should we retire the term "Context"?

  - by MrGumbe

  I'm not sure if there is a more abused term in the world of programming than "Context." A word that has a very clear meaning in the English language has somehow morphed into a hot mess in software development, where the definition where the connotation can be completely different based on what library you happen to be developing in. Tomcat uses the word context to mean the configuration of a web application. Java applets, on the other hand, use an AppletContext to define attributes of the browser and HTML tag that launched it, but the BeanContext is defined as a container. ASP.NET uses the HttpContext object as a grab bag of state - containing information about the current request / response, session, user, server, and application objects. Context Oriented Programming defines the term as "Any information which is computationally accessible may form part of the context upon which behavioral variations depend," which I translate as "anything in the world." The innards of the Windows OS uses the CONTEXT structure to define properties about the hardware environment. The .NET installation classes, however, use the InstallContext property to represent the command line arguments entered to the installation class. The above doesn't even touch how all of us non-framework developers have used the term. I've seen plenty of developers fall into the subconscious trap of "I can't think of anything else to call this class, so I'll name it 'WidgetContext.'" Do you all agree that before naming our class a "Context," we may want to first consider some more descriptive terms? "Environment", "Configuraton", and "ExecutionState" come readily to mind.

• What is the best way to do scoped finds based on access control rules in Rails?

  - by Rafael Szuminski

  Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

• importing symbols from python package into caller's namespace

  - by Paul C

  I have a little internal DSL written in a single Python file that has grown to a point where I would like to split the contents across a number of different directories + files. The new directory structure currently looks like this: dsl/ __init__.py types/ __init__.py type1.py type2.py and each type file contains a class (e.g. Type1). My problem is that I would like to keep the implementation of code that uses this DSL as simple as possible, something like: import dsl x = Type1() ... This means that all of the important symbols should be available directly in the user's namespace. I have tried updating the top-level __init__.py file to import the relevant symbols: from types.type1 import Type1 from types.type2 import Type2 ... print globals() the output shows that the symbols are imported correctly, but they still aren't present in the caller's code (the code that's doing the import dsl). I think that the problem is that the symbols are actually being imported to the 'dsl' namespace. How can I change this so that the classes are also directly available in the caller's namespace?

• Ant: simplest way to copy over a relative list of files

  - by Derek Illchuk

  Using Ant, I want to copy a list of files from one project to another, where each project has the same directory structure. Is there a way to get the following to work? <project name="WordSlug" default="pull" basedir="."> <description> WordSlug: pull needed files </description> <property name="prontiso_home" location="../../prontiso/trunk"/> <!-- I know this doesn't work, what's the missing piece? --> <target name="pull" description="Pull needed files"> <copy todir="." overwrite="true"> <resources> <file file="${prontiso_home}/application/views/scripts/error/error.phtml"/> <file file="${prontiso_home}/application/controllers/CacheController.php"/> <!-- etc. --> </resources> </copy> </target> </project> Success is deriving the paths automatically: ${prontiso_home}/application/views/scripts/error/error.phtml copied to ./application/views/scripts/error/error.phtml ${prontiso_home}/application/controllers/CacheController.php copied to ./application/controllers/CacheController.php Thanks!

• Create Dynamically table at runtime & save it in database

  - by user1548245

  I have written a code for creating table. It displays table structure on GUI form, but what I want is, when I enter values into table it should be stored in database table too. My code: <?php function display($column,$rows) { echo "<table border='1' align='center'>"; for ($iii = 0;$iii <$_POST['column'];$iii++) { echo "<tr>".$jjj."</tr>"; //display no. of <tr> for ($jjj = 0; $jjj <$_POST['rows'];$jjj++) { echo "<td>" ."<input type=\"text\" name='$iii'>"."</td>"; } } echo "</table>"; } ?>

• Specifying SOAP Headers for a Zend_Soap Service

  - by Stephen

  I have a generally straight forward web service that I've written (converting code to ZF from a Java implementation of the same service and trying to maintain the same wsdl structure as much as possible). The service loads a PHP class, rather than individual functions. The PHP class contains three different functions within it. Everything seems to be working just fine, except that I can't seem to figure out how to specify that a given function parameter should be passed as a SOAP header. I've not seen any mention of SOAP headers in the Server context, only how to pass header parameters with a client to a server. In addition to the standard parameters for the function that would be sent in the SOAP body and detailed in the docblock, I would like to specify two parameters (a username and password) that would be sent in a SOAP header. I have to assume this is possible, but haven't been able to find anything online, nor have I had any responses to a similar post on Zend's forum. Is there something that can be added in the docblock area to specify a parameter as a header (maybe in a similar fashion to using WebParam?)? Any suggestions/examples on how to get this accomplished would be greatly appreciated!

• PHP - Parse XML subitems using foreach()

  - by Nate Shoffner

  I have an XML file that needs parsing in PHP. I am currenlty using simplexml_load_file to load the file like so: $xml = simplexml_load_file('Project.xml'); Inside that XML file lies a structure like this: <?xml version="1.0" encoding="ISO-8859-1"?> <project> <name>Project 1</name> <features> <feature>Feature 1</feature> <feature>Feature 2</feature> <feature>Feature 3</feature> <feature>Feature 4</feature> </features> </project> What I am trying to do is print the <name> contents along with EACH <feature> element within <features>. I'm not sure how to do this because there is more than 1 element called <feature>. Any help is greatly appreciated.

• PHP include doesn't work

  - by Chris

  I'm not sure how simple is this to solve, but I assume I'm doing something wrong. I'm new to PHP, so bear with me, please. When I started learning PHP, I always placed all my project files into the same folder along with index.php and thus included everything like this: <?php include('./translation.php'); ?> Later on in the process of learning as I gained experience and my skill increased, I had to start using folders and place my files into sub folders. I ended up successfully including my files with the following: <?php include('../translation.php'); ?> My trouble-free coding took an unexpected turn when I decided to start using sub-sub folders. After placing all the files even deeper into the file structure I was shocked to find out that I cannot include them anymore, using: <?php include('.../translation.php'); ?> Now I'm lost. What did I do wrong? Am I to understand that I cannot include files deeper than 2 directories in the project? Should I start using a different file system?

• C: incompatible types in assignment

  - by The.Anti.9

  I'm writing a program to check to see if a port is open in C. One line in particular copies one of the arguments to a char array.

• Maintenance tool for Application Database

  - by Thierry

  Hello ! Does anybody know about a good tool which help maintaining the database of an application ? I'm working on an application which uses a database (Microsoft Sql Server). When a development requires to change something in the database (e.g., structure, data migration...), we create a script (Transact-SQL script) and add it into our revision control tool (subversion - that tool also contains our code). Each script must add a line in a log table to keep a trace of all the scripts that have been ran into a database. In order to build a database for our application, one needs to run all scripts ordered by their creation date. I'm not really happy with this technique notably because it make application migration a bit hard. If we want to install a new version of the application somewhere, e.g., migrate from version 1.3 to 2.1, we must get all the scripts between these two versions. Then run them and ensure that everything is done in a transaction... For sure we could built home-made tools to help but I wonder if some tools already exists to do that kind of job.

• C++ struct, public data members and inheritance

  - by Marius

  Is it ok to have public data members in a C++ class/struct in certain particular situations? How would that go along with inheritance? I've read opinions on the matter, some stated already here http://stackoverflow.com/questions/952907/practices-on-when-to-implement-accessors-on-private-member-variables-rather-than http://stackoverflow.com/questions/670958/accessors-vs-public-members or in books/articles (Stroustrup, Meyers) but I'm still a little bit in the shade. I have some configuration blocks that I read from a file (integers, bools, floats) and I need to place them into a structure for later use. I don't want to expose these externally just use them inside another class (I actually do want to pass these config parameters to another class but don't want to expose them through a public API). The fact is that I have many such config parameters (15 or so) and writing getters and setters seems an unnecessary overhead. Also I have more than one configuration block and these are sharing some of the parameters. Making a struct with all the data members public and then subclassing does not feel right. What's the best way to tackle that situation? Does making a big struct to cover all parameters provide an acceptable compromise (I would have to leave some of these set to their default values for blocks that do not use them)?

• CSS: 100% of container height without modifying the container

  - by Rena

  Yeah, this ugly question again. I'm writing some HTML that gets inserted into a page. I have no control over the rest of the page. The structure is something like: <table <tr <td rowspan="2"left column</td <td height="1"top row above content</td </tr <tr<td height="220"my content here</td</tr </table I can write whatever I want into that table cell (including style tags to pack in my CSS), but I can't touch anything outside of it, which means I can't set the height of any parent element (including html and body), add a doctype (it has none), etc - that already kills just about every solution I can find (all seem to be "add a doctype" and/or "give the parent container a fixed height"). What I want to do is simply have a <div fill the entire cell. Width is no problem but unsurprisingly height is being a massive pain. Writing "height: 100%" doesn't do anything unless the container has a fixed height (the height="220" attribute apparently doesn't count) or the div uses absolute positioning - and then it seems to want to use 100% of the window's height (and width even) instead of the cell's. The root of the problem is the left column varies in height, as does the content, and when the left column cell is larger than the content, it won't expand to fill the cell it's in. If I set a fixed height for the content, it'll be much larger than necessary most of the time, and if I don't, it doesn't take up all of the cell and leaves an ugly gap at the bottom.

• Designing a chain of states

  - by devoured elysium

  I want to model a kind of FSM(Finite State Machine). I have a sequence of states (let's say, from StateA to StateZ). This sequence is called a Chain and is implemented internally as a List. I will add states by the order I want them to run. My purpose is to be able to make a sequence of actions in my computer (for example, mouse clicks). (I know this has been done a zillion times). So a state is defined as a: boolean Precondition() <- Checks to see if for this state, some condition is true. For example, if I want to click in the Record button of a program, in this method I would check if the program's process is running or not. If it is, go to the next state in the chain list, otherwise, go to what was defined as the fail state (generally is the first state of them all). IState GetNextState() <- Returns the next state to evaluate. If Precondition() was sucessful, it should yield the next state in the chain otherwise it should yield the fail state. Run() Simply checks the Precondition() and sets the internal data so GetNextState() works as expected. So, a naive approach to this would be something like this: Chain chain = new Chain(); //chain.AddState(new State(Precondition, FailState, NextState) <- Method structure chain.AddState(new State(new WinampIsOpenCondition(), null, new <problem here, I want to referr to a state that still wasn't defined!>); The big problem is that I want to make a reference to a State that at this point still wasn't defined. I could circumvent the problem by using strings when refrering to states and using an internal hashtable, but isn't there a clearer alternative? I could just pass only the pre-condition and failure states in the constructor, having the chain just before execution put in each state the correct next state in a public property but that seems kind of awkward.

• Read/Write Files from the Content Provider

  - by drum

  I want to be able to create a file from the Content Provider, however I get the following error: java.io.Filenotfoundexception: /0: open file failed: erofs (read-only file system) What I am trying to do is create a file whenever an application calls the insert method from my Provider. This is the excerpt of the code that does the file creation: FileWriter fstream = new FileWriter(valueKey); BufferedWriter out = new BufferedWriter(fstream); out.write(valueContent); out.close(); Originally I wanted to use openFileOutput() but the function appears to be undefined. Anyone has a workaround to this problem? EDIT: I found out that I had to specify the directory as well. Here is a more complete snippet of the code: File file = new File("/data/data/Project.Package.Structure/files/"+valueKey); file.createNewFile(); FileWriter fstream = new FileWriter(file); BufferedWriter out = new BufferedWriter(fstream); out.write(valueContent); out.close(); I also enabled the permission <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" /> This time I got an error saying: java.io.IOException: open failed: ENOENT (No such file or directory)

• Javascript global object calls function?

  - by Troels

  Hello stackoverflow I have a very odd problem with javascript. My code is rather long so here is an example of the structure and the problem: var x = new function f() { this.id = ""; } function g(obj) { if (x.id == "") { ... obj.firstChild.setAttribute("onclick", "javascript:o();"); ... x.id = obj.id; } else if (x.id != obj.id) { ... x.id = ""; g(obj); } } function o() { ... if (something == something) { ... } else { ... x.id = ""; // if-statement of the g() function is called here? } } As you can see, the if-statement of the g() function is for some reason called or re-run upon x.id being changed. I simply cannot understand this, because they are not in the same scope, and changing a variable should under no circumstances trigger anything? Any help would be greatly appreciated.

• Optimize a views drawing code

  - by xon1c

  Hi, in a simple drawing application I have a model which has a NSMutableArray curvedPaths holding all the lines the user has drawn. A line itself is also a NSMutableArray, containing the point objects. As I draw curved NSBezier paths, my point array has the following structure: linePoint, controlPoint, controlPoint, linePoint, controlPoint, controlPoint, etc... I thought having one array holding all the points plus control points would be more efficient than dealing with 2 or 3 different arrays. Obviously my view draws the paths it gets from the model, which leads to the actual question: Is there a way to optimize the following code (inside the view's drawRect method) in terms of speed? int lineCount = [[model curvedPaths] count]; // Go through paths for (int i=0; i < lineCount; i++) { // Get the Color NSColor *theColor = [model getColorOfPath:[[model curvedPaths] objectAtIndex:i]]; // Get the points NSArray *thePoints = [model getPointsOfPath:[[model curvedPaths] objectAtIndex:i]]; // Create a new path for performance reasons NSBezierPath *path = [[NSBezierPath alloc] init]; // Set the color [theColor set]; // Move to first point without drawing [path moveToPoint:[[thePoints objectAtIndex:0] myNSPoint]]; int pointCount = [thePoints count] - 3; // Go through points for (int j=0; j < pointCount; j+=3) { [path curveToPoint:[[thePoints objectAtIndex:j+3] myNSPoint] controlPoint1:[[thePoints objectAtIndex:j+1] myNSPoint] controlPoint2:[[thePoints objectAtIndex:j+2] myNSPoint]]; } // Draw the path [path stroke]; // Bye stuff [path release]; [theColor release]; } Thanks, xonic

• Problem with inner classes of the same name in Visual C++

  - by starblue

  I have a problem with Visual C++, where apparently inner classes with the same name but in different outer classes are confused. The problem occurs for two layers, where each layer has a listener interface as an inner class. B is a listener of A, and has its own listener in a third layer above it (not shown). The structure of the code looks like this: A.h class A { class Listener { Listener(); virtual ~Listener() = 0; } [...] } B.h class B : public A::Listener { class Listener { Listener(); virtual ~Listener() = 0; } [...] } B.cpp B::Listener::Listener() {} B::Listener::~Listener() {} I get the error B.cpp(49) : error C2509: '{ctor}' : member function not declared in 'B' The C++ compiler for Renesas sh2a has no problem with this, but then it is more liberal than Visual C++ in some other respects, too. If I rename the listener interfaces to have different names the problem goes away, but I'd like to avoid that (the real class names instead of A or B are rather long). Is what I'm doing correct C++, or is the complaint by Visual C++ justified? Is there a way to work around this problem without renaming the listener interfaces?

• persist values/variables from page to page

  - by Todd

  Hello, I'm wondering if there's another solution to my problem, that's considered more the Sharepoint way. FIrstly, my site is an Internet site, not Intranet. The problem is, all I'm trying to do is save values/variables from page to page in Sharepoint. I know the issue with Session Variables, but this seems to be the only way I can see to accomplish this. I know there are webparts that can store this value, but am I wrong in thinking this won't be persisted from page to page? Basically, I'll be extending the Content Query Web Part to dynamically filter it's results based off of a variable/value. The user chooses their 'area' from a dropdown, and the CQWP in the site will change and query results based off of this value (It will be a provincial structure as it is a Canadian site, so if someone chooses the province 'Ontario', this value is saved in a global variable, and these extended CQWP that are throughout the site, will get this value, and query lists flagged as Ontario). Is Session variables the only solution? Thanks everyone!

• Process a set of files from a source directory to a destination directory in Python

  - by Spoike

  Being completely new in python I'm trying to run a command over a set of files in python. The command requires both source and destination file (I'm actually using imagemagick convert as in the example below). I can supply both source and destination directories, however I can't figure out how to easily retain the directory structure from the source to the destination directory. E.g. say the srcdir contains the following: srcdir/ file1 file3 dir1/ file1 file2 Then I want the program to create the following destination files on destdir: destdir/file1, destdir/file3, destdir/dir1/file1 and destdir/dir1/file2 So far this is what I came up with: import os from subprocess import call srcdir = os.curdir # just use the current directory destdir = 'path/to/destination' for root, dirs, files in os.walk(srcdir): for filename in files: sourceFile = os.path.join(root, filename) destFile = '???' cmd = "convert %s -resize 50%% %s" % (sourceFile, destFile) call(cmd, shell=True) The walk method doesn't directly provide what directory the file is under srcdir other than concatenating the root directory string with the file name. Is there some easy way to get the destination file, or do I have to do some string manipulation in order to do this?

• How to write a "thread safe" function in C ?

  - by Andrei Ciobanu

  Hello I am writing some data structures in C, and I've realized that their associated functions aren't thread safe. The i am writing code uses only standard C, and I want to achieve some sort of 'synchronization'. I was thinking to do something like this: enum sync_e { TRUE, FALSE }; typedef enum sync_e sync; struct list_s { //Other stuff struct list_node_s *head; struct list_node_s *tail; enum sync_e locked; }; typedef struct list_s list; , to include a "boolean" field in the list structure that indicates the structures state: locked, unlocked. For example an insertion function will be rewritten this way: int list_insert_next(list* l, list_node *e, int x){ while(l->locked == TRUE){ /* Wait */ } l->locked = TRUE; /* Insert element */ /* -------------- */ l->locked = FALSE; return (0); } While operating on the list the 'locked' field will be set to TRUE, not allowing any other alterations. After operation completes the 'locked' field will be again set to 'TRUE'. Is this approach good ? Do you know other approaches (using only standard C).

• Django, url tag in template doesn't work: NoReverseMatch

My file structure looks like this: project/ +-- frontend ¦   +-- models.py ¦   +-- urls.py ¦   +-- views.py +-- settings.py +-- templates ¦   +-- add_comment.html ¦   +-- entry.html +-- utils ¦   +-- with_template.py +-- wsgi.py My urls.py: from project.frontend.views import * from django.conf.urls import patterns, include, url urlpatterns = patterns('project.frontend.views', url(r'^entry/(?P<entry_id>\d+)/', 'entry', name="entry"), (r'^entry_list/', 'entry_list'), Then entry_list.html: {% extends "base.html" %} {% block content %} {% for entry in entries %} {% url 'entry' entry.id %} {% endfor %} {% endblock %} In views.py I have: @with_template def entry(request, entry_id): entry = Entry.objects.get(id=entry_id) entry.comments = entry.get_comments() return locals() where with_template is following decorator(but I don't think this is a case): class TheWrapper(object): def __init__(self, default_template_name): self.default_template_name = default_template_name def __call__(self, func): def decorated_func(request, *args, **kwargs): extra_context = kwargs.pop('extra_context', {}) dictionary = {} ret = func(request, *args, **kwargs) if isinstance(ret, HttpResponse): return ret dictionary.update(ret) dictionary.update(extra_context) return render_to_response(dictionary.get('template_name', self.default_template_name), context_instance=RequestContext(request), dictionary=dictionary) update_wrapper(decorated_func, func) return decorated_func if not callable(arg): return TheWrapper(arg) else: default_template_name = ''.join([ arg.__name__, '.html']) return TheWrapper(default_template_name)(arg) Do you have any idea, what may cause the problem? Great thanks in advance!
