• Good web hosting for ASP.NET MVC 1.0 app

  - by magellings

  I'm looking for hosting for an ASP.NET MVC 1.0 app. I've narrowed down with research to either asphostportal, asphostcentral, godaddy, or 1&1. I've ruled out crystaltech and softsyshosting due to price with better plans. Will be running a small e-commerce site written with ASP.NET MVC 1.0 and want to be sure it will work, as well as looking for cheapest price with best value in regards to disk space/bandwidth. And bandwidth is basically how much data can be sent from your site per month right? Any opinions appreciated as I'm finding this tough to narrow down. I know you can bin deploy MVC but heard full trust mode is required as well as some routing rules in IIS. 1&1 says they can't enable full trust. This is what I was looking at: name data(disk space/bandwidth) price MVCenabled crystal tech 500MB/50GB 7.95 + 7.95 setup 2000MB/200GB 16.95 softsyshosting 500MB/5GB 3.50 + 12/year domain 1000MB/10GB 5.84 3000MB/30GB 13.33 asphostportal 5GB/50GB 5.75 + 8.99/year yes 10GB/100GB 10.25 asphostcentral 2GB/15GB 4.99 yes 3GB/30GB 7.99/month domain free 5GB/40GB 11.99 godaddy 10GB/300GB 10.69 + 4.74/month 150GB/1500GB 6.99/month 1&1 10GB/unlimited 3.99 + free domain 150GB/unlimited 6.99 1&1 seems to be best value if MVC app will work. I'm a bit confused on bandwidth being unlimited. May seem like a good thing, but what if one website on the server is a resource hog because of this?

• Internet Explorer randomly drops sessions between pages in cakePHP

  - by Emerson Taymor

  Hello everyone, I've come across an extremely unusual bug that my team has literally no idea how to solve. Doing some research, I found some similar solutions that I thought would work, but alas did not. Here is my situation, let me know if I can provide additional insight to help solve the problem. The first step is that someone chooses a country via a flash map. Flash passes this region name (as well as a date) through the URL, which we then convert to a session. The next page contains no Flash and doesn't display the selected region, but it does hold on to it for further down the process. Everything works perfectly in Safari and Firefox; however, in IE sometimes unexpected results occur. Frequently (but not always), the session is dropped completely and no sessions are stored between the first and 2nd pages. Here are the steps that I have taken thus far, unsuccessfully: 1. Changed Security from Medium - Low 2. Changed CheckUserAgent from True - False 3. Changed storing of sessions from PHP - Database Some additional information that may be useful: I have tried printing out the session data in Debug (debug($_SESSION) on my view file and debug set to 2 in config). In Internet Explorer everything prints out as expected EXCEPT when the region and date don't get set. For example: If the region and date don't get set NOTHING is printed out for debug. I don't get the session details at the top, and I don't get the normal dump of calls at the bottom of the page either. I am not using redirection on these pages. Please let me know if you have ANY idea of what is causing this or any solutions. I am beyond frustrated and have tried as much as I can to solve this. Thanks!

• Is it possible to defer member initialization to the constructor body?

  - by Kjir

  I have a class with an object as a member which doesn't have a default constructor. I'd like to initialize this member in the constructor, but it seems that in C++ I can't do that. Here is the class: #include <boost/asio.hpp> #include <boost/array.hpp> using boost::asio::ip::udp; template<class T> class udp_sock { public: udp_sock(std::string host, unsigned short port); private: boost::asio::io_service _io_service; udp::socket _sock; boost::array<T,256> _buf; }; template<class T> udp_sock<T>::udp_sock(std::string host = "localhost", unsigned short port = 50000) { udp::resolver res(_io_service); udp::resolver::query query(udp::v4(), host, "spec"); udp::endpoint ep = *res.resolve(query); ep.port(port); _sock(_io_service, ep); } The compiler tells me basically that it can't find a default constructor for udp::socket and by my research I understood that C++ implicitly initializes every member before calling the constructor. Is there any way to do it the way I wanted to do it, or is it too "Java-oriented" and not feasible in C++? I worked around the problem by defining my constructor like this: template<class T> udp_sock<T>::udp_sock(std::string host = "localhost", unsigned short port = 50000) : _sock(_io_service) { udp::resolver res(_io_service); udp::resolver::query query(udp::v4(), host, "spec"); udp::endpoint ep = *res.resolve(query); ep.port(port); _sock.bind(ep); } So my question is more out of curiosity and to better understand OOP in C++

• MSBuild / PowerShell: Copy SQL Server 2012 database to SQL Azure via BACPAC (for Continuous Integration)

  - by giveme5minutes

  I'm creating a continuous integration MSBuild script which copies a database in on-premise SQL Server 2012 to SQL Azure. Easy right? Methods After a fair bit of research I've come across the following methods: Use PowerShell to access the DAC library directly, then use the MSBuild PowerShell extension to wrap the script. This would require installing PowerShell 3 and working out how to make the MSBuild PowerShell extension work with it, as apparently MS moved the DAC API to a different namespace in the latest version of the library. PowerShell would give direct access to the API, but may require quite a bit of boilerplate. Use the sample DAC Framework Client Side Tools, which requires compiling them myself, as the downloads available from Codeplex only include the Hosted version. It would also require fixing them to use DAC 3.0 classes as they appear to currently use an earlier version of DAC. I could then call these tools from an <Exec Command="" /> in the MSBuild script. Less boilerplate and if I hit any bumps in the road I can just make changes to the source. Processes Using whichever method, the process could be either: Export from on-premise SQL Server 2012 to local BACPAC Upload BACPAC to blog storage Import BACPAC to SQL Azure via Hosted DAC Or: Export from on-premise SQL Server 2012 to local BACPAC Import BACPAC to SQL Azure via Client DAC Question All of the above seems to be quite a lot of effort for something that seems to be a standard feature... so before I start reinventing the wheel and documenting the results for all to see, is there something really obvious that I've missed here? Is there pre-written script that MS has released that I have not yet uncovered? There's an command in the GUI of SQL Server Management Studio 2012 that does EXACTLY what I'm trying to do (right click on local database, click "Tasks", click "Deploy Database to SQL Azure"). Surely if it's a few clicks in the GUI it must be a single command on the command line somewhere??

• Show NSSegmentedControl menu when segment clicked, despite having set action

  - by Justin Williams

  I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?

• What are the common compliance standards for software products?

  - by Jay

  This is a very generic question about software products. I would like to know what compliance standards are applicable to any software product. I know that question gives away nothing. So, here is an example to what I am referring to. CiSecurity Security Certification/Compliance lists out products ceritified by them to be compliant to the standards published at their website, i.e, cisecurity.org. Compliance could be as simple as answering a questionnaire for your product and approved by a thirdparty like cisecurity or it could apply to your whole organization, for instance, PCI-DSS compliance. I would be very interested in knowing the standards that products you know/designed/created, comply to. To give you the context behind this question: I am the developer of a data-masking tool. The said tool helps mask onscreen html text in a banking web application using filters. So, for instance, if the bank application lists out user information with ssn, my product when integrated with the banking product, automatically identifies ssn pattern and masks it into a pre-defined format.So, I have my product marketing team wanting more buzz words like compliance to be able to sell it to more banking clients. Hence, understanding "compliances that apply to products" is a key research item for me at this point. By which I meant, security compliances. Appreciate all your help and suggestions.

• Machine leaning algorithm for data classification.

  - by twk

  Hi all, I'm looking for some guidance about which techniques/algorithms I should research to solve the following problem. I've currently got an algorithm that clusters similar-sounding mp3s using acoustic fingerprinting. In each cluster, I have all the different metadata (song/artist/album) for each file. For that cluster, I'd like to pick the "best" song/artist/album metadata that matches an existing row in my database, or if there is no best match, decide to insert a new row. For a cluster, there is generally some correct metadata, but individual files have many types of problems: Artist/songs are completely misnamed, or just slightly mispelled the artist/song/album is missing, but the rest of the information is there the song is actually a live recording, but only some of the files in the cluster are labeled as such. there may be very little metadata, in some cases just the file name, which might be artist - song.mp3, or artist - album - song.mp3, or another variation A simple voting algorithm works fairly well, but I'd like to have something I can train on a large set of data that might pick up more nuances than what I've got right now. Any links to papers or similar projects would be greatly appreciated. Thanks!

• how to split a very large database on sql server

  - by ken jackson

  I have a 90 GB SQL Server database that I want to make more manageable. It stores stock data from 50+ different stocks from 2009 and 2010, and each stock is a separate table. Some tables have hundreds of millions of rows, and other have just a few million. What I want to do is somehow split the database, so that I don't have a single database file that is 90 GB. What I want is to be able to somehow magically split all the tables so that I can backup the 2009 data once and not have to keep on including it in the backup every time I backup the entire database, however, I would like the 2009 data to be included whenever I do a query. Is partitioning the database the way to go? Will it do the above for me, or will I need some other solution? I research partitioning, but I wasn't sure if that would solve all my problems. I wasn't able to find anything that would tell me whether or not it would migrate prexisting data, or whether it only worked for newly inserted data. Any help or pointers would be much appreciated. Thanks in advance, Ken

• Read Java in as Hex

  - by James

  Hi, I have tried to solve this but I keep coming up with stuff that is no help I'm sure this is easy (when you know how of course ;) ) What I would like to do is read in a file using a byte stream like below: while((read = in.read()) != -1){ //code removed to save space Integer.toHexString(read); System.out.println(read); } When it prints out the Hex to the screen it will print out numbers fine e.g 31 13 12 0 but when it comes to a hex code that should be 01 31 it will print 0 131. I want to read it in to a variable like you would see in a hex editor i.e 00 11 21 31 no single numbers as i need to scan the whole file and look for patterns which I know how to do I'm just stuck on this :/ so in short i need a variabe to contain the two hex characters i.e int temp = 01 not int temp = 0 , I hope this all makes sense, I'm a little confused as it's 3am! If anyone knows how to do this I would be most greatful, p.s thanks for the help in advance this site has saved me loads of research and have learnt a lot! Many thanks.

• What can I read from the iPad Camera Connection Kit?

  - by HELVETICADE

  I'm building a small controller device that I'd like to partner with a computer. I've settled on using OSC out from my custom built hardware and am pretty satisfied with what I can get from WOscLib. Two goals I'd like to achieve are portability and a very ratio between battery:computing power, and this has lured me towards using iPhoneOS to accomplish my goals. I think the iPad would suit my needs perfectly, except that using wifi to broadcast OSC out from my device requires a third device and would destroy the goal of portability, whilst also introducing potential latency and stability headaches. My question is pretty simple: Can I push my OSC-out FROM my controller TO an iPad via USB and the Camera Connection Kit? If I could accomplish this, the two major goals of my project would be fulfilled very nicely. This seems like it should be a simple little question, but researching this obsessively over the past few weeks has left me more almost more uncertain than if I had done no research at all. I'd really like some more confidence before I go down this route, and it seems like it should be possible. Any insight would be very, very appreciated.

• Really cool way to create custom UITabBar for iPhone app?

  - by ludicco

  Hi, I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc. Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar: So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :) Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation. Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version. nice Items separators with beveled vertical lines. diferrent background image for the tabBar different height for the tabBar At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect. If someone knows about a very good tutorial on how to do this it would be great for clarifying what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder :) I am just starting on this world off app development for iOS so if you could help me on that it would be really appreciated Thanks a lot in advance

• Database design MySQL using foreign keys

  - by dscher

  I'm having some a little trouble understanding how to handle the database end of a program I'm making. I'm using an ORM in Kohana, but am hoping that a generalized understanding of how to solve this issue will lead me to an answer with the ORM. I'm writing a program for users to manage their stock research information. My tables are basically like so: CREATE TABLE tags( id INT AUTO_INCREMENT NOT NULL PRIMARY KEY, tags VARCHAR(30), UNIQUE(tags) ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE stock_tags( id INT AUTO_INCREMENT NOT NULL PRIMARY KEY, tag_id INT NOT NULL, stock_id INT NOT NULL, FOREIGN KEY (tag_id) REFERENCES tags(id), FOREIGN KEY(stock_id) REFERENCES stocks(id) ON DELETE CASCADE ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE notes( id INT AUTO_INCREMENT NOT NULL, stock_id INT NOT NULL, notes TEXT NOT NULL, FOREIGN KEY (stock_id) REFERENCES stocks(id) ON DELETE CASCADE, PRIMARY KEY(id) ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE links( id INT AUTO_INCREMENT NOT NULL, stock_id INT NOT NULL, links VARCHAR(2083) NOT NULL, FOREIGN KEY (stock_id) REFERENCES stocks(id) ON DELETE CASCADE, PRIMARY KEY(id) ) ENGINE=INNODB DEFAULT CHARSET=utf8; How would I get all the attributes of a single stock, including its links, notes, and tags? Do I have to add links, notes, and tags columns to the stocks table and then how do you call it? I know this differs using an ORM and I'd assume that I can use join tables in SQL. Thanks for any help, this will really help me understand the issue a lot better.

• How should I organize complex SQL views in Rails?

  - by Benjamin Oakes

  I manage a research database with Ruby on Rails. The data that is entered is primarily used by scientists who prefer to have all the relevant information for a study in one single massive table for use in their statistics software of choice. I'm currently presenting it as CSV, as it's very straightforward to do and compatible with the tools people want to use. I've written many views (the SQL kind, not the Rails HTML/ERB kind) to make the output they expect a reality. Some of these views are quite large and have a fair amount of complexity behind them. I wrote them in SQL because there are many calculations and comparisons that are more easily done with SQL. They're currently loaded into the database straight from a file named views.sql. To get the requested data, I do a select * from my_view;. The views.sql file is getting quite large. Part of the problem is that we're still figuring out what the data we collect means, so there's a lot of changes being made to the views all the time -- and a ton of them are being created. Many of them need to be repeatable. I've recently run into issues organizing and testing these views. Rails works great for user interface stuff and business logic, but I'm not aware of much existing structure for handling the reporting we require. Some options I've thought of: Should I move them into the most relevant models somehow? Several of the views interact with each other, which makes this situation more complex than just doing a single find_by_sql, so I don't know if they should only be part of the model. Perhaps they should be treated as a "view" in the MVC sense? (That is, they could be moved into app/views/ and live alongside the HTML, perhaps as files named something like my_view.csv.sql which return CSV.) How would you deal with a complex reporting problem like this?

• What are the skills a Drupal Developer needs?

  - by hfidgen

  I'm trying to write out a list of key Drupal competencies, mainly so I can confirm what I know, don't know and don't know I don't know. (Thanks D. Rumsfeld for that quote!) I think some of these are really broad, for instance there's quite a difference between making a functional theme and creating a theme with good SEO, load times and so on, but I'm hoping you could assume that a half decent web developer would look after that anyway. Just interested to see what people here feel is also important. Able to install Drupal on a server (pretty obvious). Able to research and install modules to meet project requirements Able to configure all the basic modules and core settings to get a site running Able to create a custom Theme from scratch which validates with good HTML/CSS and also pays attention to usability and accessibility. (Whilst still looking kick-ass). Able to use Hooks in the theme template.php to alter forms, page layout and other core functionality Can make forms from scratch using the API - with validation and posting back to the DB/email Can use Views to create blocks or pages, use php snippets as arguments, etc. Can create custom modules from scratch utilising core hooks and other hooks.

• Return latitude/longitude based on entered address

  - by Don

  I'm building a php based application for a client to enter in addresses for their customers' buildings. They'd like the ability to view the location on a map (either as individuals or grouped in a city search). What I'm trying to accomplish is a lookup once the address is entered into a form that populates the database, so after they enter in the addresss, city, state, zip (these are all US locations) they could click a "get lat/long info" link/button that would check to make sure the data is complete, then would lookup the address and return the latitude/longitude into the appropriate form fields. Then the form could be submitted to store the info, and I could later just pull the lat/long when plotting on a map. 1) Does this make sense, or would I be better off just doing the lookup when it's time to plot it? 2) Does anyone have any pointers to solve this problem? I've seen some of the Google/Yahoo API's but it looks like this is more based on the plotting a point part. I may be able to modify it to suit my needs, but I'm just trying to cut some research time posting here with the hopes one of you may have a more direct route. I'll RTFM if I have to... Thanks, D.

• Alternatives to the Entity Framework for Serving/Consuming an OData Interface

  - by Egahn

  I'm researching how to set up an OData interface to our database. I would like to be able to pull/query data from our DB into Excel, as a start. Eventually I would like to have Excel run queries and pull data over HTTP from a remote client, including authentication, etc. I've set up a working (rickety) prototype so far, using the ADO.NET Entity Data Model wizard in Visual Studio, and VSTO to create a test Excel worksheet with a button to pull from that ADO.NET interface. This works OK so far, and I can query the DB using Linq through the entities/objects that are created by the ADO.NET EDM wizard. However, I have started to run into some problems with this approach. I've been finding the Entity Framework difficult to work with (and in fact, also difficult to research solutions to, as there's a lot of chaff out there regarding it and older versions of it). An example of this is my being unable to figure out how to set the SQL command timeout (as opposed to the HTTP request timeout) on the DataServiceContext object that the wizard generates for my schema, but that's not the point of my question. The real question I have is, if I want to use OData as my interface standard, am I stuck with the Entity Framework? Are there any other solutions out there (preferably open source) which can set up, serve and consume an OData interface, and are easier to work with and less bloated than the Entity Framework? I have seen mention of NHibernate as an alternative, but most of the comparison threads I've seen are a few years old. Are there any other alternatives out there now? Thanks very much!

• ASP.NET MVC Membership, Get new UserID

  I am trying to register a new user and also understand how to get the new userID so i can start creating my own user tables with a userID mapping to the asp.net membership user table. Below is my code: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Register(string userName, string email, string position, string password, string confirmPassword) { ViewData["PasswordLength"] = MembershipService.MinPasswordLength; ViewData["position"] = new SelectList(GetDeveloperPositionList()); if (ValidateRegistration(userName, email, position, password, confirmPassword)) { // Attempt to register the user MembershipCreateStatus createStatus = MembershipService.CreateUser(userName, password, email); if (createStatus == MembershipCreateStatus.Success) { FormsAuth.SignIn(userName, false /* createPersistentCookie */); return RedirectToAction("Index", "Home"); } else { ModelState.AddModelError("_FORM", ErrorCodeToString(createStatus)); } } // If we got this far, something failed, redisplay form return View(); } I've done some research and many sites inform me to use Membership.GetUser().ProviderUserKey; but this throws an error as Membership is NULL. I placed this line of code just above "return RedirectToAction("Index", "Home");" within the if statement. Please can someone advise me on this... Thanks in advance

• Why not put all braces inline in C++/C#/Java/javascript etc.?

  - by DanM

  Of all the conventions out there for positioning braces in C++, C#, Java, etc., I don't think I've ever seen anyone try to propose something like this: public void SomeMethod(int someInput, string someOtherInput) { if (someInput > 5) { var addedNumber = someInput + 5; var subtractedNumber = someInput - 5; } else { var addedNumber = someInput + 10; var subtractedNumber = someInput; } } public void SomeOtherMethod(int someInput, string someOtherInput( { ... } But why not? I'm sure it would take some getting used to, but I personally don't have any difficulty following what's going on here. I believe indentation is the dominant factor in being able to see how code is organized into blocks and sub-blocks. Braces are just visual noise to me. They are these ugly things that take up lines where I don't want them. Maybe I just feel that way because I was weened on basic (and later VB), but I just don't like braces taking up lines. If I want a gap between blocks, I can always add an empty line, but I don't like being forced to have gaps simply because the convention says the closing brace needs to be on its own line. I made this a community wiki because I realize this is not a question with a defined answer. I'm just curious what people think. I know that no one does this currently (at least, not that I've seen), and I know that the auto-formatter in my IDE doesn't support it, but are there are any other solid reasons not to format code this way, assuming you are working with a modern IDE that color codes and auto-indents? Are there scenarios where it will become a readability nightmare? Better yet, are you aware of any research on this?

• Possibility of a custom Contacts field with a set list of values and Contacts lookup performance

  - by areyling

  I'm pretty sure it's not viable to do what I'd like to based on some initial research, but I figured it couldn't hurt to ask the community of experts here in case someone knows a way. I'd like to create a custom field for contacts that the user is able to edit from the main Contacts app; however, the user should only be allowed to select from a list of four specific values. A short list of string values would be ideal, but an int with a min/max range would suffice. I'm interested in knowing if it's possible either way, but also wondering if it make sense to go this route performance wise. More specifically, would it be better to look up a contact (based on a phone number) each time a call or SMS message is received or better to store my own set of data (consisting of name, numbers, and the custom field) and just syncing contact info in a thread every so often? Or syncing contacts the first time the app is run and then registering for changes using ContentObserver? Here is a similar question with an answer that explains how to add a custom field to a contact. Thanks in advance.

• Possible to capture all events in a web browser?

  - by David

  I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.

• Career day in kindergarten

  - by Péter Török

  I was invited to the kindergarten group of my elder daughter to talk and answer the kids' questions about my profession. There are 26 kids of age 4-6 in the group, plus 3 teachers who are fairly scared of anything related to programming and IT themselves, but bold enough to learn new tricks. I would have about 20-30 minutes, without projector or anything. They have an old computer though, which by its look may be a 486, and I am not even sure if it's functioning. My research turned up excellent earlier threads, with lots of good tips: How would you explain your job to a 5-year old? Career Day: how do I make “computer programmer” sound cool to 8 year olds? What things can I teach a group of children about programming in one day? My situation is different from each of the above though: the latter ones are concerned with older children, while the first one is about talking to a single kid (or elder person)—a group of 20 is a whole different challenge. How can I teach the kids and their teachers about programming in a fun way?

• How do I put an ASP.NET website project and class library projects in one .sln file on Subversion

Website projects don't have .sln files, but I'm sure I've read in my past research that you can make a blank solution and put your website and class library projects in it. After answers to my previous questions, this is the direction that I'm going (based slightly on [http://amadiere.com/blog/2009/06/multiple-subversion-projects-in-one-visual-studio-solution-using-svnexternals/][1]: /websites /website1 /trunk /website1 /libraries /library1 /trunk /library1 /library2 /trunk /library2 /etc... Then I planed on using svn:externals to copy /library1, /library2, and so on into the working_copy/websites/website1/ folder. I want my team members to be able to checkout the /trunk folder for website1 and get a .sln file, /library1 external, /library2 external, etc. I want that .sln file to contain the website1 website project, and all of the library external projects. Hopefully that would look something like: /working_copy /websites /website1 /trunk /website1 /library1 (svn:external of libraries/library1/trunk/library1) /library2 (svn:external of libraries/library2/trunk/library2) /etc. website1.sln So, at the end of all of this, the goal is that my teammates check out the trunk, open the solution, and everyone has the exact same solution. When we commit, everything is committed appropriately to subversion (the website code, and the libraries are committed to their appropriate place on the repo). How have others solved these issues? How can I make a .sln file that my team members and I can share in this manner? [1]: "This Article"

• Handling Types Defined in Plug-ins That Are No Longer Available

  - by Chris

  I am developing a .NET framework application that allows users to maintain and save "projects". A project can consist of components whose types are defined in the assemblies of the framework itself and/or in third-party assemblies that will be made available to the framework via a yet-to-be-built plug-in architecture. When a project is saved, it is simply binary-serialised to file. Projects are portable, so multiple users can load the same project into their own instances of the framework (just as different users may open the same MSWord document in their own local copies of MSWord). What's more, the plug-ins available to one user's framework might not be available to that of another. I need some way of ensuring that when a user attempts to open (i.e. deserialise) a project that includes a type whose defining assembly cannot be found (either because of a framework version incompatibility or the absence of a plug-in), the project still opens but the offending type is somehow substituted or omitted. Trouble is, the research I've done to date does not even hint at a suitable approach. Any ideas would be much appreciated, thanks.

• Significance in R

  - by Gemsie

  Ok, this is quite hard to explain, but I'm at a complete loss what to do. I'm a relative newcomer to R and although I can completely admire how powerful it is, I'm not too good at actually using it.... Basically, I have some very contrived data that I need to analyse (it wasn't me who chose this, I can assure you!). I have the right and left hand lengths of lots of people, as well as some numeric data that shows their sociability. Now I would like to know if people who have significantly different lengths of hand are more or less sociable than those who have the same (leading into the research that 'symmetrical' people are more sociable and intelligent, etc. I have got as far as loading the data into R, then I have no idea where to go from there. How on Earth do I start to separate those who are close to symmetrical to those who aren't to then start to do the analysis? Ok, using Sasha's great advice, I did the cor.test and got the following: Pearson's product-moment correlation data: measurements$l.hand - measurements$r.hand and measurements$sociable t = 0.2148, df = 150, p-value = 0.8302 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.1420623 0.1762437 sample estimates: cor 0.01753501 I have never used this test before, so am unsure how to intepret it...you wouldn't think I was on my fourth Scientific degree would you?! :(
