• Using ASP.NET session state with Silverlight (PRISM)

  - by Jon Andersen

  Hi, The scenario: I have a PRISM application developed in Silverlight (4), and I'm using a ASP.NET server side application to host several web-services (which, in turn, accesses WCF-services, but that's not really important here). The Silverlight application must be able to call the web services cross-domain (meaning that the web services isn't necessarily on the same server hosting the silverlight application). The Silverlight application consists of several modules, each accessing the ASP.NET web-services. I do not have much experience with Silverlight and PRISM, but as far as I can see, this is not a very unusual scenario... The problem: My challange is, that when 2 different modules access the web-services, I get 2 new sessions on the web-server. I would have thought that since both modules live on the same HTML-page (and then also in the same browser session), they would get the same session on the web-server...? I have tried to make the web-service Proxy-client globally available in the container (using Unity), by registering an instance (using Container.RegisterInstance), and then getting this instance whenever a module needs to make a web-service call (using Container.Resolve), but this doesn't seem to help. However, any calls made within the same module always gets the same session on the server. Can anyone see what I'm missing here...? Thanks! Jon

• Strategy game programming in Java, how the map and unit classes should work/relate each other.

  - by Gabriel A. Zorrilla

  As a way of learning Java i'm doing a little strategy game. You have a game map and military units. The gamemap and the units are Jpanels which are binded together in another class called GameWindow, which has a JLayeredPane where the gamepap is below the units. Every time i click a unit (and therefore, the JPane) I can get the unit's information. The problem comes when i want to move a unit... each unit is self drawn inside it's Jpanel, how do i represent the change in position over the gamemap? I'm thinking about reloading the whole game window based on a position change of a unit (because the JPAnels that represent the units are created in the GameWindow, not drawn in the gamemap). Another more elegant option, should be repainting the whole map, with the units. But that way the units would lose it's status of objects (no more JPAnels, just being drawn in the gamemap paint() method), and how would i tell if one unit is clicked? I dont know how people with more experience in games handle the class structure in strategy games. I believe i have the right structure (map, game units, each one an object) but I'm having difficulties making it work together. Here is a snapshot of the map with a couple of units:

• How to access webbrowser object on this code? C++

  - by extintor

  I found this example http://www.mvps.org/user32/webhost.cab that host an Internet Explorer WebBrowser object, and it uses this code to access the object void webhostwnd::CreateEmbeddedWebControl(void) { OleCreate(CLSID_WebBrowser,IID_IOleObject,OLERENDER_DRAW,0,&site,&storage,(void**)&mpWebObject); mpWebObject->SetHostNames(L"Web Host",L"Web View"); // I have no idea why this is necessary. remark it out and everything works perfectly. OleSetContainedObject(mpWebObject,TRUE); RECT rect; GetClientRect(hwnd,&rect); mpWebObject->DoVerb(OLEIVERB_SHOW,NULL,&site,-1,hwnd,&rect); IWebBrowser2* iBrowser; mpWebObject->QueryInterface(IID_IWebBrowser2,(void**)&iBrowser); VARIANT vURL; vURL.vt = VT_BSTR; vURL.bstrVal = SysAllocString(L"http://google.com"); VARIANT ve1, ve2, ve3, ve4; ve1.vt = VT_EMPTY; ve2.vt = VT_EMPTY; ve3.vt = VT_EMPTY; ve4.vt = VT_EMPTY; iBrowser->put_Left(0); iBrowser->put_Top(0); iBrowser->put_Width(rect.right); iBrowser->put_Height(rect.bottom); iBrowser->Navigate2(&vURL, &ve1, &ve2, &ve3, &ve4); VariantClear(&vURL); iBrowser->Release(); } I don't have much experience with cpp, I want to know how to access that same ie object (to use Navigate2 for example) from a button or something like that. How could I achieve this?

• Choosing a method for a webservice

  - by Wrikken

  I'm asked to set up a new webservice which should be easily usable in whatever language (php, .NET, Java, etc.) possible. Of course rolling my own can be done, accepting different content-types (xml / x-www-form-urlencoded (normal post) / json / etc.), but an existing method or mechanism would of course be prefered, cutting down time spent on development for the consumers of the service. The webservice does accept modifications / sets (it is not only simply data retrieval), but those will most likely be quite a lot less then gets (we estimate about 2.5% sets, 97.5 gets). The term webservice here indicates the protocol should go over HTTP, not being able to implement it totally client sided (javascript in the end-users browser etc.), as it needs specific user authentication. Both gets and sets are pretty light on the parameter count (usually 1 to 4). Methods like REST (which I'd prefer for only gets), XML-RPC & SOAP (might be a bit overkill, but has the advantage of explicitly defined methods and returns) are the usual suspects. What in your opinion / experience is the most widely 'spoken' and most easily implementable protocol in different languages (seen from the consumers' viewpoint) which could fullfill this need?

• Idea for a small project, should I use Python?

  - by Robb

  I have a project idea, but unsure if using Python would be a good idea. Firstly, I'm a C++ and C# developer with some SQL experience. My day job is C++. I have a project idea i'd like to create and was considering developing it in a language I don't know. Python seems to be popular and has piqued my interests. I definitely use OOP in programming and I understand Python would work fine with that style. I could be way off on this, I've only read small bits and pieces about the language. The project won't be public or anything, just purely something of my own creation do dabble in at home. So the project would essentially represent a simple game idea I have. The game would consist roughly these things: Data structures to hold specific information (would be strongly typed). A way to output the gamestate for the players. This is completely up in the air, it can be graphical or text based, I don't really care at this point. A way to save off game data for the players in something like a database or file system. A relatively easy way for me to input information and a 'GO' button which processes the changes and obviously creates a new gamestate. The game would function similar to a board game. Really nothing out of the ordinary when I look back at that list. Would this be a fun way to learn Python or should I select another language?

• Modeling complex hierarchies

  - by jdn

  To gain some experience, I am trying to make an expert system that can answer queries about the animal kingdom. However, I have run into a problem modeling the domain. I originally considered the animal kingdom hierarchy to be drawn like -animal -bird -carnivore -hawk -herbivore -bluejay -mammals -carnivores -herbivores This I figured would allow me to make queries easily like "give me all birds", but would be much more expensive to say "give me all carnivores", so I rewrote the hierarchy to look like: -animal -carnivore -birds -hawk -mammals -xyz -herbivores -birds -bluejay -mammals But now it will be much slower to query "give me all birds." This is of course a simple example, but it got me thinking that I don't really know how to model complex relationships that are not so strictly hierarchical in nature in the context of writing an expert system to answer queries as stated above. A directed, cyclic graph seems like it could mathematically solve the problem, but storing this in a relational database and maintaining it (updates) would seem like a nightmare to me. I would like to know how people typically model such things. Explanations or pointers to resources to read further would be acceptable and appreciated.

• ISBNs are used as primary key, now I want to add non-book things to the DB - should I migrate to EAN

  - by fish2000

  I built an inventory database where ISBN numbers are the primary keys for the items. This worked great for a while as the items were books. Now I want to add non-books. some of the non-books have EANs or ISSNs, some do not. It's in PostgreSQL with django apps for the frontend and JSON api, plus a few supporting python command-line tools for management. the items in question are mostly books and artist prints, some of which are self-published. What is nice about using ISBNs as primary keys is that in on top of relational integrity, you get lots of handy utilities for validating ISBNs, automatically looking up missing or additional information on the book items, etcetera, many of which I've taken advantage. some such tools are off-the-shelf (PyISBN, PyAWS etc) and some are hand-rolled -- I tried to keep all of these parts nice and decoupled, but you know how things can get. I couldn't find anything online about 'private ISBNs' or 'self-assigned ISBNs' but that's the sort of thing I was interested in doing. I doubt that's what I'll settle on, since there is already an apparent run on ISBN numbers. should I retool everything for EAN numbers, or migrate off ISBNs as primary keys in general? if anyone has any experience with working with these systems, I'd love to hear about it, your advice is most welcome.

• Docs for auto-generated methods in Ruby on Rails

  - by macek

  Rails has all sorts of auto-generated methods that I've often times struggled to find documentation for. For example, in routes.rb, if I have: map.resources :projects do |p| p.resources :tasks end This will get a plethora of auto-generate path and url helpers. Where can I find documentation for how to work with these paths? I generally understand how to work with them, but more explicit docs might help me understand some of the magic that happens behind the scenes. # compare project_path(@project) project_task_path(@project, @task) # to project_path(:id => @project.id) project_task_path(:project_id => @project.id, :id => @task.id) Also, when I change an attribute on a model, @post.foo_changed? will be true. Where can I find documentation for this and all other magical methods that are created like this? If the magic is there, I'd love to take advantage of it. And finally: Is there a complete resource for config.___ statements for environment.rb? I was able to find docs for Configuration#gem but what attributes can I set within the stubs like config.active_record.___, config.action_mailer.___, config.action_controller.___, etc. Again, I'm looking for a complete resource here, not just a settings for the examples I provided. Even if you can only answer one of these questions, please chime in. These things seem to have been hiding from me and it's my goal to get them some more exposure, so I'll be upvoting all links to docs that point me to what I'm looking for. Thanks! ps, If they're not called auto-generated methods, I apologize. Someone can teach me a lesson here, too :) Edit I'm not looking for tutorials here, folks. I have a fair amount of experience with rails; I'm just looking for complete docs. E.g., I understand how routing works, I just want docs where I can read about all of the usage options.

• HTML file: add annotations through IHTMLDocument

  - by peterchen

  I need to add "annotations" to existing HTML documents - best in the form of string property values I can read & write by name. Apparently (to me), meta elements in the header seem to be the common way - i.e. adding/modifying elements like <head> <meta name="unique-id_property-name" content="property-value"/> ... </head> Question 1: Ist that "acceptable" / ok, or is there a better way to add meta data? I have a little previous experience with getting/mut(il)ating HTML contents through the document in an web browser control. For this task, I've already loaded the HTML document into a HTMLDocument object, but I'm not sure how to go on: // what I have IHTMLDocument2Ptr doc; doc.CreateInstance(__uuidof(HTMLDocument)); IPersistFile pf = doc; pf->Load(fileName, STGM_READ); // everything ok until here Questions 2: Should I be using anything else than HTMLDocument? Questions 3..N: How do I get the head element? How do I get the value of a meta element with a given name? How do I set the value of a meta element (adding the item if and only if it doesn't exist yet)? doc->all returns a collection of all tags, which I can enumerate even though count returns 0. I could scan that for head, then scan that for all meta where the name starts with a certain string, etc. - but this feels very clumsy.

• ASP.net site looks completely different on IE, Firefox, and Chrome; why?

  - by DavidR

  I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well. Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?

• Integrating Magento with a simple static website.

  - by ExtraLean

  Magento is an awesomely powerful ecommerce platform. That said, it is also very complex, and I'd like to know if there is a relatively simple way to utilize Magento as our mISV site's backend to fulfill orders without actually "using" Magento's framework to build the site, run the site, etc. In other words, I don't want to use the built-in CMS, etc. since we have a static website already built. I'd just like our Buy Now buttons to utilize the checkout stuff, and would like to be able to use the back-end part to keep track of orders etc. I was able to accomplish this "fairly" easily with osCommerce, but Magento is proving to be a little more difficult to wrap my head around since I've only started looking at it for a few days now. I found another person asking this same exact question on the Magento wiki (along with several others in the forum), and none of them ever receive a reply for some reason. I noticed that there are may Magento experts on Stack Overflow, so I thought I'd give it a go here. This is an example of one question asked by someone on their wiki, and it captures the essence of what I'm trying to accomplish: Hi, as far as I understand, all shopping cart/eCommerce solutions I see are full featured PHP driven web sites. This means that all the pages the user interacts with, are server generated, and thus, the experience, is tied to the magento framework/workflow. I’d like to integrate bits and pieces of eCommerce/shopping cart in my existing website. Effectively, I’d like to have: 1) on a product information page, a “buy now/add to cart” button that adds to a cart 2) on every page, a view cart/checkout option 3) on a checkout page, with additional content already in place, having the magento “checkout” block integrated in the page (and not the entire page generated from Magento). Have any of you done this with Magento? This is for a simple one-product website so any advice you could share would be highly appreciated.

• Should client-server code be written in one "project" or two?

  - by Ricket

  I've been beginning a client-server application. At first I naturally created two projects in Eclipse, two source control repositories, etc. But I'm quickly seeing that there is a bit of shared code between the two that would probably benefit to sharing instead of copying. In addition, I've been learning and trying test-driven development, and it seems to me that it would be easier to test based on real client components rather than having to set up a huge amount of code just to mock something, when the code is probably mostly in the client. My biggest concern in merging the client and server is of security; how do I ensure that the server pieces of the code do not reach an user's computer? So especially if you are writing client-server applications yourself (and especially in Java, though this can turn into a language-agnostic question if you'd like to share your experience with this in other languages), what sort of separation do you keep between your client and server code? Are they just in different packages/namespaces or completely different binaries using shared libraries, or something else entirely? How do you test the code together and yet ship separately?

• Strange Behaviour in Swift: constant defined with LET but behaving like a variable defined with VAR

  - by Sam

  Stuck on the below for a day! Any insight would be greatly appreciated. The constant in the first block match0 behaves as expected. The constant defined in the second block does not behave as nicely in the face of a change to its "source": var str = "+y+z*1.0*sum(A1:A3)" if let range0 = str.rangeOfString("^\\+|^\\-|^\\*|^\\/", options: NSStringCompareOptions.RegularExpressionSearch){ let match0 = str[range0] println(match0) //yields "+" - as expexted str.removeRange(range0) println(match0) //yields "+" - as expected str.removeRange(range0) println(match0) //yields "+" - as expected } if let range1 = str.rangeOfString("^\\+|^\\-|^\\*|^\\/", options: NSStringCompareOptions.RegularExpressionSearch){ let match1 = str[range1] println(match1) //yields "+" as expected str.removeRange(range1) println(match1) //!@#$ OMG!!!!!!!!!!! a constant variable has changed! This prints "z" } The following are the options I can see: match1 has somehow obtained a reference to its source instead of being copied by value [Problem: Strings are value types in Swift] match1 has somehow obtained a closure to its source instead of just being a normal constant/variable? [Problem: sounds like science fiction & then why does match0 behave so well?] Could there be a bug in the Swift compiler? [Problem: Experience has taught me that this is very very very rarely the solution to your problem...but it is still in beta]

• Every flash uploader giving bad progress values.

  - by Mike Boers

  The file upload script I wrote early last year for an internal website has been misbehaving oddly on a number of machines. On some machines it consistently works fine, on others it consistently misbehaves. I am having exactly the same problem with YUI Uploader, SWFUpload (2.2 and 2.5a), and Uploadify. On the misbehaving machines, the progress event (or callback as the case may be) is reporting the upload going far too quickly. It is progressing around 9 or 10MB/s, instead of the 50 or 60kb/s that is actually going on. The progress bar fills up very quickly, and then no more progress events are triggered. A few minutes later the completion event will trigger when the upload is actually done. I must emphasize that the file upload does proceed normally, even though the progress being reported is very wrong. The progress events are reporting a correct file size, but the reported amount uploaded is usually way too high, and it appears that it is always a multiple of 2^16 (65536). I'm only having this problem with Firefox 3.5 on Windows XP, all of which have various subversions of Flash 10. Has anyone heard of this happening, or have any idea what is going on? (I'm off to go file a number of bug reports, but hopefully someone here has some previous experience with this.)

• What effects has working in rotating shifts on programming teams?

  - by eKek0

  I work in a bank, and the boss now want's that we, the programming team, work on rotating shifts. He wants that sometimes we work from 7am to 3pm, and sometimes on 11.30am to 7.30pm. He says that we will be more productive working this way, because he has worked with teams just like that and he just knows that. Nobody of the team wants this change, but we don't know how to effectively reject this new rule. I was trying to find some empirical (or almost) evidence about how rotating shifts affects performance of programming teams, and I couldn't. I had read something about rotating shifts, but not exactly about the effect of this on programming teams. Do you know any research about rotating shifts on programming teams? Did you have any experience with this kind of work? EDIT: Other teams of the company, like the database administrators team, the help desk team, the communication team or the network administrators team are already working in rotating shifts, and they don't like this but they do it anyway. I think the boss want that we work on rotating shifts too because of them, but since only we do programming I think the effects of rotating shifts could be, at least, different for us.

• Delphi Client-Server Application using Firebird 2.5 embedded connection error

  - by Japster

  0 down vote favorite 1 share [fb] share [tw] I have got a lengthy question to ask. First of all Im still very new when it comes to Delphi programming and my experience has beem mostly developing small single user database applications using ADO and an Access database. I need to take the transition now to a client server application and this is where the problem starts. I decided to use Firebird 2.5 embeded as my database, as it is open source, and it is can be used with the interbase components in Delphi and that multiple clients can access the database simultanously. So I followed the interbase tutorial in Delphi. I managed to connect the client to the server and see the data in the example (While both are running on my pc), but when i tried to move the client to another pc, keeping the server on mine and running it to see if I can connect to the server it gave me the following error. Exception EIdSocketError in module clientDemo.exe at 0029DCAC. Socket Error # 10061 Connection refused. I understand that this might be because the host is defined as localhost in the client. But here is my first question. In the TSQLConncetion you can set die hostname under Driver-Hostname. The thing I want to know is how do you do this at run time, as I cannot get the property when I try and make an edit box to allow the user to enter the value and then set it via code like for example: SQLConncetion1.Driver.Hostname := edtHost.text; This cannot be done this way and the only way I see you can set the hostname is with the object inspector, but that is not available at runtime and I need to set the hostname on the client when the program is running the first time, so how do you set the hostname/IP address at runtime? Im using Delphi XE2 There is still a lot of questions to come especially when it comes to deployment, but I will take this piece by piece and I appreciate the advice.

  WPF Silverlight Windows phone 7 w/ Silverlight iPhone OS w/ Objective-C Cocoa w/ Objective-C ASP.NET Android Facebook FBML HTML5 I will be graduating with B.S. in Computer Science soon and have to decide what do I want to learn from this list. I believe it's better to focus on one thing, master it and build up a portfolio to enhance my resume. Bachelor's Degree with no experience, no portfolio won't do me any good. It won't get me a job by itself. I need to have something that will greatly boost my resume. What would it be? iPhone development? ASP.NET web development? Facebook development? Or completely something else that I haven't listed? I understand it's natural for silverlight developers to say "Learn Silverlight", and iPhone developers say "Learn iPhone SDK and Objective-C".

• How to calculate the height of the text rectangle from an NSString?

  - by mystify

  I know there is this one: sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: But since the CGSize always has the same height and doesn't adjust to any shrinked text or whatsoever, the CGSize is not telling how heigh the text is. Example: Make a UILabel with 320 x 55 points and put a loooooooooooooong text in there. Let the label shrink the text down. Surprise: CGSize.height remains the same height even if the text is so tiny that you need a microscope. Ok so after banging my head against my macbook pro which is half way broken now, the only think that can help is that nasty actualFontSize. But the font size is in pica I think, it's not really what you get on the screen, isn't it? When that font size is 10, is my text really 10 points heigh at maximum? Once in a while I tried exactly that, and as soon as the text had a y or some character that extends to below (like that tail of an y does), it is out of bounds and the whole text is bigger than 10 points. So how would you calculate the real text height for a single line uilabel without getting a long beard and some hospital experience?

• Creating ODT and PDF files as end result

  - by Bill Zimmerman

  Hello, I've been working on an app to create various document formats for a while now, and I've had limited success. Ideally, I'd like to dynamically create a fairly simple ODT/PDF/DOC file. I've been focusing my efforts on ODT, because it is editable, and open enough that there are several tools which will convert it to any of the other formats I need. The problem is that the ODT XML files are NOT simple, and there aren't any good-quality API's I could find (especially in python). So far, I've had the most success creating a template ODT file, and then manipulating the DOM in python as needed. This is ok generally, but is quickly becoming inadequate and requires too much tweaking every single time I need to alter one of the templates. The requirements are: 1) Produce a simple document that will have lists, paragraphs, and the ability to draw simple graphics on the page (boxes, circles, etc...) 2) The ability to specify page size, and the different formats should generally print the exact same output when sent to a printer My questions: 1) Are there any other ways I can produce ODT/PDF/DOC files? 2) Would LaTeX be acceptable? I've never really used it, does anyone have experience converting LaTeX files into other formats? 3) Would it be possible to use HTML? There are a lot of converters online. Technically you can specify dimensions in mm/cm, etc..., but I am worried that the printed output will differ between browsers/converters.... Any other ideas?

• What are the essential Java libraries and utilities for a returning dynamic language user?

  - by jbwiv

  Guys, Long time Java developer here, but I've spent more time working with Ruby over the past 3 years or so as far as web applications go. I really have enjoyed it, but there are concerns I've uncovered that I won't cover here. Now that I've found the Play! framework, I'm thrilled about the prospect of having a Rails-like experience with Java's speed and reliability. Aside from what Play! provides out of the box, I'm looking for recommendations on "can't miss" libraries and tools for the Java developer used to pragmatic, dynamic experiences. I've found Project Lombok, which looks like a very intriguing way to eliminate a lot of the boiler plate, unnecessary Java noise. What else should I know about? I know Google has released quite a few libraries over the past three years that I've heard mentioned on the Java Posse, but I can't recall exactly what they are. I'm sure I've missed others in my absence. So, what makes up your essential Java toolbox these days? Thanks for your answers!

• How do I ensure my C# software can access the internet in a Citrix + ISA environment?

  - by TomFromThePool

  Hi everyone, A client recently informed us that deployment of our software in their environment has failed due to a proxy error when the software attempts to access the internet. The client has a combination of Citrix and Microsoft's ISA server. The software allows the use of a proxy and the ability to manually enter authentication information, or automatically retrieve the current system proxy settings. The error returned is the standard 407 authentication error, but the client assures us that they have entered the authentication information required. They have also shown us the snippet of the ISA error logs which identify the client as Anonymous and the authentication protocol as Basic. I have a few questions I suppose: How should I go about dealing with the ISA server in my code? I have no real experience with this environment and am assuming that the ISA server is treated like any other proxy. If I am mistaken, what should I be doing? Does ISA allow the administrator to disallow specific authentication protocols - and if this is the case and 'Basic' auth is disallowed, would it still return a 407 error? Could the Citrix environment have caused this issue? Is there any particular way to ensure that my software will work in such an environment? Code-samples would be much appreciated. I have neither a Citrix test server or an ISA server at my disposal to carry out testing on this so I am currently trying to identify possible causes before I make the case for investment in a more robust testing environment. Thanks for any help!

• Modelling deterministic and nondeterministic data separately

  - by Superstringcheese

  I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

• Is WordPress MVC compliant?

  - by kovshenin

  Some people consider WordPress a blogging platform, some think of it as a CMS, some refer to WordPress as a development framework. Whichever it is, the question still remains. Is WordPress MVC compliant? I've read the forums and somebody asked about MVC about three years ago. There were some positive answers, and some negative ones. While nobody knows exactly what MVC is and everybody thinks of it in their own way, there's still a general concept that's present in all the discussions. I have little experience with MVC frameworks and there doesn't seem to be anything about the framework itself. Most of the MVC is done by the programmer, am I right? Now, going back to WordPress, could we consider the core rewrite engine (WP_Rewrite) the controller? Queries & plugin logic as the model? And themes as the view? Or am I getting it all wrong? Thanks ;)

• Should we deploy a Webkit browser for our intranet applications?

  - by Jeff Meatball Yang

  At my place of employment, we are increasingly finding it difficult to develop for IE, which was historically the easiest browser to target, from an intranet-app point of view. It was already deployed. It already understood NTLM authentication, thus well integrated with our domain-level security. It had neat, albeit non-standard features such as XMLDOM and XmlHTTP. Now, we are increasingly irritated by issues presented by IE: There are several versions: IE 7, 8, and soon 9 beta, which all have slightly different issues related to performance, functionality (especially re:security and zones), and aesthetics. IE 7 and 8 are slower than Webkit-based browsers. Period. There are technology limitations such as missing canvas element, CSS bugs, etc. that make it hard to use 3rd party packages or even consistently write code across IE versions. Users are increasingly using Firefox or Chrome, even for intranet use. Does anyone have experience with making a transition? Any advice would be welcome.

• Creating a cocoa Application without nib files/fully pragmatic

  - by Moddy

  Yes, I know this goes against the whole MVC principle! However, I'm just trying to whip up a pretty trivial application - and I've pretty much implemented it pragmatically. However, I have a problem... I create an Empty Project, copy all the frameworks over and set the build settings - and I get errors about the executable.. or lack of executable. The build settings all appear fine, but it tells me there is no executable - it will build + run fine.. however it doesn't run. There is no error either - it just appears to run very fast and cleanly! Unless I try and run gdb which politely tells me I need to give it a file first.. Running… No executable file specified. Use the "file" or "exec-file" command. So I created a Cocoa Application, removed all the stuff I didn't need (i.e the MainMenu.xib file..) and now I can compile my code perfectly.. however it dies with complaining that its "Unable to load nib file: MainMenu, exiting" I have gone through the Project Symbols and see that the code actually relies upon the nib file heavily, even if you don't touch it code-wise. (MVC again I guess..) So my question is - is there a simple way to compile just what you code, no added nib files, just the code you write and the frameworks you add? I assume it would be a blank project but my experience tells me otherwise?!
