  • Does jQuery strip some html elements from a string when using .html()?

    - by Nic Hubbard
    I have a var that contains a full html page, including the head, html, body, etc. When I pass that string into the .html() function, jQuery strips out all those elements, such as body, html, head, etc, which I don't want. My data var contains: <html> <head> <title>Untitled Document</title> </head> <body> </body> </html> // data is a full html document string data = $('<div/>').html(data); // jQuery stips my document string! alert(data.find('head').html()); I am needing to manipulate a full html page string, so that I can return what is in the element. I would like to do this with jQuery, but it seems all of the methods, append(), prepend() and html() all try to convert the string to dom elements, which remove all the other parts of a full html page. Is there another way that I could do this? I would be fine using another method. My final goal is to find certain elements inside my string, so I figured jQuery would be best, since I am so used to it. But, if it is going to trim and remove parts of my string, I am going to have to look for another method. Ideas?

  • Graphviz or Dynagraph for Graph-manipulation Program?

    - by noahlavine
    I'm looking into writing a program that will show a graph to the user. The graph will change over time (the user should be able to right-click on a graph item and ask for more detail, which will pop out new bits of the graph), and the user might be able to drag parts of the graph around. I would ideally also like to be able to specify the relative layout of certain parts of the graph myself while leaving the overall layout up to a library, but that's not essential. I'm trying to decide on a graph layout library to use. As far as I can tell, the two leading candidates are Graphviz and Dynagraph. The Dynagraph website suggests that Graphviz is for drawing static graphs, and that Dynagraph was forked from Graphviz and contains algorithms for graphs that will be updated. It has a sample program called Dynasty that does exactly what I want. However, the Graphviz site contains an example program called Lefty which seems to do exactly what I want. Graphviz also seems to be much more widely used, judging by Google (and SO) results. Finally, I'd like to code the GUI part in a language like Python or Scheme, which makes me a bit hesitant to use C++ because I understand it's harder to interface that to interpreters. So my question is, which library is better for what I'm trying to do? Do they both have strong and weak points? Has one of them actually ceased development and is just leaving its website up to confuse me? (I've seen http://stackoverflow.com/questions/464000/simple-dynamic-graph-display-for-c and http://stackoverflow.com/questions/2376987/open-source-libraries-to-design-directed-graphs, but I can't tell whether they're right about the Graphviz or Dynagraph choice because of Lefty and also the language issue.)

  • Creating customized .dmg files upon download

    - by Marten
    I want to distribute a cross-platform application for which the executable file is slightly different, depending on the user who downloaded it. This is done by having a placeholder string somewhere in the executable that is replaced with something user-specific upon download. The webserver that has to do these string replacements is a Linux machine. For Windows, the executable is not compressed in the installer .exe, so the string replacement is easy. For uncompressed Mac OS X .dmg files, this is also easy. However, .dmg files that are compressed with either gzip or bzip2 are not so easy. For example, in the latter case, the compressed .dmg is not one big bzip2-compressed disk image, but instead consists of a few different bzip2-compressed parts (with different block sizes) and a plist suffix. Also, decompressing and recompressing the different parts with bzip2 does not result in the original data, so I'm guessing Apple uses some different parameters to bzip2 than the command-line tool. Is there a way to generate a compressed .dmg from an uncompressed one on Linux (which does not have hdiutil)? Or maybe another suggestion for creating customized applications without pregenerating them? It should work without any input by the user.

  • Modularity in Flex

    - by Fernando
    I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

  • Getting the size of the window WITHOUT title/notification bars

    - by Anidamo
    Hi there, I've been playing around with Android development and one of the things I'd like to be able to do is dynamically create a background image for my windows, similar to the one below. This is from my BlackBerry app. It consists of three separate parts, the bottom right logo, the top left watermark, and the bottom right name. It works independent of screen size because the BlackBerry app just gets all three parts and generates an appropriately sized bitmap using the screen width and height. Since Android has quite a bit more screen resolution possibilities I need to be able to generate backgrounds on the fly like this. However, I have not found any way to get the height/width of the window in Android. I can get the screen resolution, but that includes the application title bar and the notification bar, which is unacceptable. I'd like to know how to get the size of my window, or screen resolution minus the title and notification bars. I think this might be possible using the dimensions of my layout managers but I cannot get the height/width of them in the onCreate method so I'm at a little bit of a loss. Thanks.

  • Reading UTF-8 XML and writing it to a file with Python

    - by Harri
    I'm trying to parse UTF-8 XML file and save some parts of it to another file. Problem is, that this is my first Python script ever and I'm totally confused about the character encoding problems I'm finding. My script fails immediately when it tries to write non-ascii character to a file, but it can print it to command prompt (at least in some level) Here's the XML (from the parts that matter at least, it's a *.resx file which contains UI strings) <?xml version="1.0" encoding="utf-8"?> <root> <resheader name="foo"> <value>bar</value> </resheader> <data name="lorem" xml:space="preserve"> <value>ipsum öä</value> </data> </root> And here's my python script from xml.dom.minidom import parse names = [] values = [] def getStrings(path): dom = parse(path) data = dom.getElementsByTagName("data") for i in range(len(data)): name = data[i].getAttribute("name") names.append(name) value = data[i].getElementsByTagName("value") values.append(value[0].firstChild.nodeValue.encode("utf-8")) def writeToFile(): with open("uiStrings-fi.py", "w") as f: for i in range(len(names)): line = names[i] + '="'+ values[i] + '"' #varName='varValue' f.write(line) f.write("\n") getStrings("ResourceFile.fi-FI.resx") writeToFile() And here's the traceback: Traceback (most recent call last): File "GenerateLanguageFiles.py", line 24, in writeToFile() File "GenerateLanguageFiles.py", line 19, in writeToFile line = names[i] + '="'+ values[i] + '"' #varName='varValue' UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 2: ordinal not in ran ge(128) How should I fix my script so it would read and write UTF-8 characters properly? The files I'm trying to generate would be used in test automation with Robots Framework.

  • How to access this data in PHP?

    - by George Edison
    Okay. Now I give up. I have been playing with this for hours. I have a variable name $data. The variable contains these contents: array ( 'headers' => array ( 'content-type' => 'multipart/alternative; boundary="_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_"', ), 'ctype_parameters' => array ( 'boundary' => '_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_', ), 'parts' => array ( 0 => stdClass::__set_state(array( 'headers' => array ( 'content-type' => 'text/plain; charset="iso-8859-1"', 'content-transfer-encoding' => 'quoted-printable', ), 'ctype_primary' => 'text', )), ), ) I removed some non-essential data. I want to access the headers value (on the second line above) - simple: $data->headers I want to access the headers value (on the fourteenth line after the stdClass:: stuff) - how? How can I possibly access the values within the stdClass::__set_state section? I tried var_export($data->parts); but all I get is NULL

  • How to add a Web Part Zone to a SharePoint wiki page?

    - by Hitesh
    Hi, I have a team site. I understand that the default home page of a team site is a wiki page. I want to add a web part zone to this page. How can I do that? By default it already has Web Part Zone -. You can use SharePoint designer to add a web part to this zone and it works fine. But you are not able to add a web part to this zone using SharePoint web UI? Ususally when you have a web part zone in a page, using SharePoint web UI, it allows to you add/remove a web part. But it is not the case with the web part zone on the default home page of a team site. Also is there any way I can add a web part zone to this page? I do know that you can easily add web parts into wiki page content. But I want to add a new web part zone where users can add/remove web parts. Thanks, Hitesh

  • Simple code to expire Drupal cookie?

    With a single click this simple script will do a multi-logout of: Moodle Elgg 2 MyBB's and (not) Drupal. <?php setcookie( 'Elgg', '', -3600, '/', '.domain.com', false, false); setcookie( 'http_auth_ext_complete', '1', -3600, '/d/', '.domain.com', false, false); // setcookie( 'http_auth_ext_complete', '1', -3600, '/d/', 'domain.com', false, false); setcookie( 'mybbuser', '', -3600, '/', '.domain.com', false, false); setcookie( 'mybbuser', '', -3600, '/bb/', '.domain.com', false, false); // unset all 3 Moodle cookies, the lazy way if (isset($_SERVER['HTTP_COOKIE'])) { $cookies = explode(';', $_SERVER['HTTP_COOKIE']); foreach($cookies as $cookie) { $parts = explode('=', $cookie); $name = trim($parts[0]); setcookie($name, '', time()-1000); setcookie($name, '', time()-1000, '/'); } } ?> This works on four sites but the Drupal cookie won't quit. How can I do the same with Drupal? Note: Drupal uses 'host' instead of 'domain', neither with or without the '.' works so far. Thank you.

  • How to deploy RSWebParts.cab manually?

    - by denni
    I'm using the SSRS 2005 Web parts to display my reports in a MOSS 2007 SP1 Portal. I have successfully installed the Web parts in my development, testing, and UAT servers using the following command: stsadm -o addwppack -filename path/to/RSWebParts.cab. But when I tried running the same command in the production server, it will give me the following error: This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application. I know I usually will get this kind of error message when I tried to deploy my custom solutions having no Web application resources (such as web.config entries) to a specific Web application. But this is not my custom solution, it is an out-of-the-box SSRS Web part and it does have resources scoped to a Web application. I tried to even use different combination of the command by providing the -url, -globalinstall, and -force switches but it still give the same error. The configuration of the 4 servers are exactly the same, both from software and hardware perspectives. All other features are working properly on the production server. I even tried to extract the cab file manually to the bin folder of my Web application, then modify the Web.config manually to include the SafeControl element (copied from the manifest.xml inside the cab file). But it gave me an error saying it couldn't find the resources file. Even though, I extracted the whole file, including the resource files in the bin folder. Is there anyone who can help me resolve the problem? Thanks a lot.

  • Downloading jQuery UI: Ok, so what part of this mess do I copy to the server?

    - by Martha
    From the "should be simple, but..." files: Trying to get started with jQuery UI. Went to the site, used their custom builder thingy to assemble the parts I need, made myself a custom theme using the Theme Roller, downloaded the zip file thus produced, unzipped it on my local drive. Ok, so I have 37 folders, 311 files, and a total of 2.4 MB. Ain't no way in hell all this is going on the server. What parts do I need to put there? 'css' 'custom-theme': jquery-ui-1.8.custom.css, 'images' subfolder with 12 .png images 'development-bundle' 'demos': demos.css, index.html, plus 18 subfolders, but I'm guessing "not needed" 'docs': 17 .html files, but again, I'm guessing "not needed" 'external': 4 .js files, one .css 'themes': 'base' and 'custom-theme' subfolders, each with 8 or 9 .css files and an 'images' subfolder with about a dozen images 'ui': 25 .js files, an 'i18n' subfolder with 53 .js files, and a 'minified' subfolder with 24 .js files 'js': jquery-1.4.2.min.js and jquery-ui-1.8.custom.min.js Also, the file structure. Our server is set up something like this: root admin (administrative tools) css forms (the gist of the site lives here) images include (asp code snippets that are used by multiple pages) js (just a few things right now, like an ancient wheezing spelling checker) As far as I can tell, the jQuery css files assume that (1) each theme is in its own folder, and (2) each folder has its own images subfolder. How can I convince it otherwise? i.e. put the necessary .js files in the 'js' folder, the .css files in the 'css' folder, and the images in the 'images' folder?

  • SharePoint extensions for VS - which version have I got?

    - by Javaman59
    I'm using Visual Studio 2008, and have downloaded VSeWSS.exe 1.2, to enable Web Part development. I am new to SP development, and am already bewildered by the number of different versions of SP, and the VS add-ons. This particular problem has come up, which highlights my confusion. I selected Add - New Project - Visual C# - SharePoint- Web Part, accepted the defaults, and VS created a project, with the main file WebPart1.cs using System; using System.Runtime.InteropServices; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Serialization; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using Microsoft.SharePoint.WebPartPages; namespace WebPart1 { [Guid("9bd7e74c-280b-44d4-baa1-9271679657a0")] public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart { public WebPart1() { } protected override void CreateChildControls() // <-- This line { base.CreateChildControls(); // TODO: add custom rendering code here. // Label label = new Label(); // label.Text = "Hello World"; // this.Controls.Add(label); } } } The book I'm following, Essential SharePoint 2007, by Jeff Webb, has the following for the default project - using System; <...as previously> namespace WebPart1 { [Guid("9bd7e74c-280b-44d4-baa1-9271679657a0")] public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart { // ^ this is a new style (ASP.NET) web part! [author's comment] protected override void Render(HtmlTextWriter writer) // <-- This line { // This method draws the web part // TODO: add custom rendering code here. // Label label = new Label(); // writer.Write("Output HTML"); } } } The real reason for my concern is that in this chapter of the book the author frequently mentions the distinction between "old style" web parts, and "new style" web parts, as noted in his comment on the Render method. What's happened? Why has my default Web Part got a different signature to the authors?

Here is a list of all zip codes: http://www.census.gov/tiger/tms/gazetteer/zips.txt (I only care about the 2nd column) This is really a compression problem. I would like to do this for fun. OK, now that's out of the way, here is a list of optimizations over a straight hashtable that I can think of, feel free to add anything I have not thought of: Break zipcode into 2 parts, first 2 digits and last 3 digits. Make a giant if-else statement first checking the first 2 digits, then checking ranges within the last 3 digits. Or, covert the zips into hex, and see if I can do the same thing using smaller groups. Find out if within the range of all valid zip codes there are more valid zip codes vs invalid zip codes. Write the above code targeting the smaller group. Break up the hash into separate files, and load them via Ajax as user types in the zipcode. So perhaps break into 2 parts, first for first 2 digits, second for last 3. Lastly, I plan to generate the JavaScript files using another program, not by hand. Edit: performance matters here. I do want to use this, if it doesn't suck. Performance of the JavaScript code execution + download time. Edit 2: JavaScript only solutions please. I don't have access to the application server, plus, that would make this into a whole other problem =)

  • does lucene search function work in large size document?

    - by shaon-fan
    Hi,there I have a problem when do search with lucene. First, in lucene indexing function, it works well to huge size document. such as .pst file, the outlook mail storage. It can build indexing file include all the information of .pst. The only problem is to large sometimes, include very much words. So when i search using lucene, it only can process the front part of this indexing file, if one word come out the back part of the indexing file, it couldn't find this word and no hits in result. But when i separate this indexing file to several parts in stupid way when debugging, and searching every parts, it can work well. So i want to know how to separate indexing file, how much size should be the limit of searching? cheers and wait 4 reply. ++++++++++++++++++++++++++++++++++++++++++++++++++ hi,there, follow Coady siad, i set the length to max 2^31-1. But the search result still can't include what i want. simply, i convert the doc word to string array[] to analyze, one doc word has 79680 words include the space and any symbol. when i search certain word, it just return 300 count, actually it has more than 300 results. The same reason, when i search a word in back part of the doc, it also couldn't find. //////////////set the length idexwriter.SetMaxFieldLength(2147483647); ////////////////////search IndexSearcher searcher = new ndexSearcher(Program.Parameters["INDEX_LOCATION"].ToString()); Hits hits = searcher.Search(query); This is my code, as others same. I found that problem when i need to count every word hits in a doc. So i also found it couldn't search word in back part of doc. pls help me to find, is there any set searcher length somewhere? how u meet this problem.

  • Is there a standard for storing normalized phone numbers in a database?

    - by Eric Z Beard
    What is a good data structure for storing phone numbers in database fields? I'm looking for something that is flexible enough to handle international numbers, and also something that allows the various parts of the number to be queried efficiently. [Edit] Just to clarify the use case here: I currently store numbers in a single varchar field, and I leave them just as the customer entered them. Then, when the number is needed by code, I normalize it. The problem is that if I want to query a few million rows to find matching phone numbers, it involves a function, like where dbo.f_normalizenum(num1) = dbo.f_normalizenum(num2) which is terribly inefficient. Also queries that are looking for things like the area code become extremely tricky when it's just a single varchar field. [Edit] People have made lots of good suggestions here, thanks! As an update, here is what I'm doing now: I still store numbers exactly as they were entered, in a varchar field, but instead of normalizing things at query time, I have a trigger that does all that work as records are inserted or updated. So I have ints or bigints for any parts that I need to query, and those fields are indexed to make queries run faster.

  • Find three numbers appeared only once

    - by shilk
    In a sequence of length n, where n=2k+3, that is there are k unique numbers appeared twice and three numbers appeared only once. The question is: how to find the three unique numbers that appeared only once? for example, in sequence 1 1 2 6 3 6 5 7 7 the three unique numbers are 2 3 5. Note: 3<=n<1e6 and the number will range from 1 to 2e9 Memory limits: 1000KB , this implies that we can't store the whole sequence. Method I have tried(Memory limit exceed): I initialize a tree, and when read in one number I try to remove it from the tree, if the remove returns false(not found), I add it to the tree. Finally, the tree has the three numbers. It works, but is Memory limit exceed. I know how to find one or two such number(s) using bit manipulation. So I wonder if we can find three using the same method(or some method similar)? Method to find one/two number(s) appeared only once: If there is one number appeared only once, we can apply XOR to the sequence to find it. If there are two, we can first apply XOR to the sequence, then separate the sequence into 2 parts by one bit of the result that is 1, and again apply XOR to the 2 parts, and we will find the answer.

  • Are MEF's ComposableParts contracts instance-based?

    - by Dave
    I didn't really know how to phrase the title of my questions, so my apologies in advance. I read through parts of the MEF documentation to try to find the answer to my question, but couldn't find it. I'm using ImportMany to allow MEF to create multiple instances of a specific plugin. That plugin Imports several parts, and within calls to a specific instance, it wants these Imports to be singletons. However, what I don't want is for all instances of this plugin to use the same singleton. For example, let's say my application ImportManys Blender appliances. Every time I ask for one, I want a different Blender. However, each Blender Imports a ControlPanel. I want each Blender to have its own ControlPanel. To make things a little more interesting, each Blender can load BlendPrograms, which are also contained within their own assemblies, and MEF takes care of this loading. A BlendProgram might need to access the ControlPanel to get the speed, but I want to ensure that it is accessing the correct ControlPanel (i.e. the one that is associated with the Blender that is associated with the program!) This diagram might clear things up a little bit: As the note shows, I believe that the confusion could come from an inherently-poor design. The BlendProgram shouldn't touch the ControlPanel directly, and instead perhaps the BlendProgram should get the speed via the Blender, which will then delegate the request to its ControlPanel. If this is the case, then I assume the BlendProgram needs to have a reference to a specific Blender. In order to do this, is the right way to leverage MEF and use an ImportingConstructor for BlendProgram, i.e. [ImportingConstructor] public class BlendProgram : IBlendProgram { public BlendProgram( Blender blender) {} } And if this is the case, how do I know that MEF will use the intended Blender plugin?

  • Creating content for rails-based applications

    - by Matthias Hryniszak
    Hi, I'm facing a problem of cleaning up my application in Ruby on Rails. What I have is a pretty standard 3-panel, header and footer layout where different parts of the screen contain different functionality. By that I mean for example that the header contains (among others) a select that allows one to select parts of the application and a context-dependent menu. The main content area contains obviously the most interactive stuff whereas side panels contain quick-links with stuff like shopping-cart preview, list of potentially attractive products for the customer, a selector to narrow down the list of options... I was wondering how do I go about simplifying the design. Right now I have the stuff that provides data for the "common" stuff (as opposed to direct content that's placed in the center) called from all the actions (with a filter) but that doesn't feel right for me. I've read that "components" are also not the way to go for obvious performance reasons. Is there something that's more like component-oriented (other frameworks do have that kind of stuff - Grails: <ui:include ../>, ASP.NET MVC: <% Html.RenderAction() %>)? Best regards, Matthias.

  • Who architected / designed C++'s IOStreams, and would it still be considered well-designed by today'

    - by stakx
    First off, it may seem that I'm asking for subjective opinions, but that's not what I'm after. I'd love to hear some well-grounded arguments on this topic. In the hope of getting some insight into how a modern streams / serialization framework ought to be designed, I recently got myself a copy of the book Standard C++ IOStreams and Locales by Angelika Langer and Klaus Kreft. I figured that if IOStreams wasn't well-designed, it wouldn't have made it into the C++ standard library in the first place. After having read various parts of this book, I am starting to have doubts if IOStreams can compare to e.g. the STL from an overall architectural point-of-view. Read e.g. this interview with Alexander Stepanov (the STL's "inventor") to learn about some design decisions that went into the STL. What surprises me in particular: It seems to be unknown who was responsible for IOStreams' overall design (I'd love to read some background information about this — does anyone know good resources?); Once you delve beneath the immediate surface of IOStreams, e.g. if you want to extend IOStreams with your own classes, you get to an interface with fairly cryptic and confusing member function names, e.g. getloc/imbue, uflow/underflow, snextc/sbumpc/sgetc/sgetn, pbase/pptr/epptr (and there's probably even worse examples). This makes it so much harder to understand the overall design and how the single parts co-operate. Even the book I mentioned above doesn't help that much (IMHO). Thus my question: If you had to judge by today's software engineering standards (if there actually is any general agreement on these), would C++'s IOStreams still be considered well-designed? (I wouldn't want to improve my software design skills from something that's generally considered outdated.)

  • Changing character encoding in MySQL, PHP scripts, HTML

    - by Sandman
    So, I have built on this system for quite some time, and it is currently outputting Latin1 (ISO-8859-1) to the web browser, and this is the components: MySQL - all data is stored with the Latin1 character set PHP - All PHP text files are stored on disk with Latin1 encoding HTML - The output has the http-equiv="content-type" content="text/html; charset=iso-8859-1" meta tag So, I'm trying to understand how the encoding of the different parts come into play in my workflow. If I open a PHP script and change its encoding within the text editor to UTF-8 and save it back to disk and reload the web browser, the text is all messed up - unless the text comes from the DB. If I change the encoding of the DB to UTF-8 and keep the PHP files in latin1 I have to use utf8_decode() for the data to display correctly. And if I change the HTML code the browser will read it incorrectly. So yeah, I realise that if I want to "upgrade" to UTF8, I have to update all three parts of this setup for it to work correctly, but since it's a huge system with some 180k lines of PHP code and millions of posts in a lot of databases/tables, I don't want to start something like this without understanding everything correctly. What haven't I thought about? What could mess this up beyond fixing? What are the procedures for changing the encoding of an entire MySQL installation and what's the easiest way to change the encoding of hundreds or thousands of PHP files on disk? The META tag is luckily added dynamically, so I'll change that in one place only :) Let me hear about your experiences with this.

  • Multiple on-screen view controllers in iPhone apps

    - by Felixyz
    I'm creating a lot of custom views and controllers in a lot of my apps and so far I've mostly set them up programmatically, with adjustments and instantiations being controlled from plists. However, now I'm transitioning to using Interface Builder as much as possible (wish I had done that before, was always on my back-list). Apple is recommending against having many view controllers being simultaneously active in iPhone apps, with a couple of well-known exceptions. I've never fully understood why it should be bad to have different parts of the interface belong to different controllers, if they have no interdependent functionality at all. Does having multiple controllers risk messing up the responder chain, or is there some other reason that it's not recommended, except for the fact that it's usually not needed? What I want to be able to do is design reusable views and controls in IB, but since a nib is not associated with a view, but with a view controller, it seems I'd have to have different parts of the screen be connected to different controllers. I know it's possible to have other objects than view controllers being instantiated from nibs. Should I look into how to create my own alternative more light-weight controllers (that could be sub-controllers of a UIViewController) which could be instantiated from nibs?
