  • Database backup regardless of backup made through a control panel?

    - by developer
    I know that all CMS or CMC platforms have some sort of walkthrough for their users to fully backup and restore the database or the whole website. While we all can perform such backups (and there are even plugins which automate the whole procedure) and restore them in necessity (such as when we migrate to a new server), one can also backup the whole website by means of such control panels as Directadmin or Cpanel. Now, I just want to know if it is necessary for us to do database or website backups the way they are described by a specific CMC or CMS developer even after we perform a whole website backup in a control panel such as DA? An example of such CMS platforms is moodle. Moodle Docs describes how we can backup and restore moodle in here. So do we, out of necessity, have to make the backup the way described, or we can simply do it the Control panel way? Thanks

  • When I try to click and launch some of the links set to open in new window, it is being treated as a pop-up window [migrated]

    - by Test Developer
    For the past few days, we are facing issue with the chrome browser behavior. This is related to opening links set to open in new tab/window. The details are as follow: I have a collection of links and each link points to different resource to be opened in a new tab/window. The code is as follow: <a class="cssClass" rid="1114931" href="http://www.domain.com/resources/abc.html" title="Link1" tabindex="4">Link 1</a> And there are few checks/filters over accessing the resources which have been implemented as onClick handler over the links. In case any of the validations fails, the onClick handler returns false and the default behavior of the link does not happens i.e. links does not get open. One of such (last) checks includes AJAX call in sync mode. The code is as follow: var link_clickHandler = function(evt/* Event */) { var objTarget = jQuery(evt.target); if(check1) { return false; } else if(check2) { return false; } else if(check3) { var blnRetVal = false; jQuery.ajax( { "async" : false, "type" : "GET", "contentType" : "application/json; charset=utf-8", "url" : "index.php", "data" : 'resourceid=' + intResourceId, "dataType" : "json", "forceData" : true, "success" : function(data) { if(check1) { blnRetVal = true; } } "error" : function(error) { } } ); return blnRetVal; } }; jQuery("a.cssClass").live("click", link_clickHandler); ISSUE: The issue is that Chrome is behaving very weirdly manner. In case all of the checks are passed and onClick handler returns true, sometimes the resource get opened in a new tab/window and sometimes it get opened as a pop-up (which should never). Tried to capture any pattern but could not succeed. Any solution or even helping in understanding behavior would be really appreciated.

  • Index page content identical to page 1 of a gallery-type website

    - by WordPress Developer
    I have a gallery type website, e.g. a site that lists blog posts or pictures in a paginated manner. However, I have 2 pages that have identical content: example.com/index.html example.com/page/1 Page 2, 3 and so on have different content naturally. However, for SEO purposes, what is the best way of telling Google that page 1 is identical to index.html? Should I 302 redirect index.html to /page/1 so index.html is non-existent, so to say or should I put a canonical tag in /page/1 (but not on /page/2) that points to index.html?

    i have seen through other questions on the topic but most are a bit old. I looking for a good editor for developing on PHP in Linux(ubuntu). Here is my requirements Basic editor features Free Light-Weight Syntax highlighting Code Folding (class,function,if/else/while/foreach block) Code completion Invalid Syntax/Error highlighting as you type Auto code intending Snippet support(pieces of custom or language specific codes that i can insert) Extendable support It would be great if it had the following Debugging support WYSIWYG Code formatting Framework support(cakephp/yii/zend/smarty) Testing support Todo Native look and feel(Gnome) Flex/ROR support is welcome but not a requirement Mysql support I have tried the following editors Netbeans - it bloated, resource hogging and doesnt not have a native look and feel. Eclipse is okay but i cant fold if/while blocks and slow. Gedit can be extended and i have tried it but still i could not fold code or show error. I currently use Geany but it doesn't inform me of syntax errors as i type. If you have ways to solve the problems with above editors they too are also welcome

  • Cocos2D 2.0 - masking a sprite

    - by Desperate Developer
    I have read this tutorial about how to mask sprites using Cocos2D 2.0. http://www.raywenderlich.com/4428/how-to-mask-a-sprite-with-cocos2d-2-0 But the author talks about OpenGL ES textures and vertices as they were common knowledge. My knowledge about OpenGl is zero raised to infinity. All I want is to use a rectangle to mask a sprite to it. How I would do in Photoshop using a rectangle as mask (yes, I want to clip a sprite to the rectangle bounds and no, I do not want to use the ClippingNode solution, that do not works for animation/scaling etc.). So, can you guys translate the klingon language used in this tutorial and tell how a solid rectangle can be used to mask a sprite in Cocos2D? I am desperate, as my username states. I am searching this for a week and have tried several solutions without satisfactory results. Please help me. Thanks!

  • Character creation using spritesheets

    - by Patrick Developer
    I am currently creating a 2D fighting game and have implemented a system where upon starting a new game, the player is presented with the option to create a custom character. I have a set of string arrays set with values that correspond to hair, headgear, chest, lower body and shoes. When done selecting a variety of items from the lists, a code is generated based off the index of each item (i.e 01123), which is then used to assign the correct Spritesheet to the player character. This has already presented a lot of work as I have had to create quite a few spreadsheets based of possible combinations, but I am now looking at a massive amount of work to implement each variation. I have started to look into setting layers for each item to reduce workload, but I am also looking at having different stances for the character - Depending on the currently equipped weapon - so this may present a lot of work either way. My question is, do I have any alternatives or am I stuck creating masses of Spritesheets to cover all combinations? As a side note, how much impact will assigning layered items have on overall performance?

  • Applying to a company while personally working on a comparable project

    - by Developer Art
    That's going to be an unusual question but here it goes. I'm entertaining the thought to send my docs to a place which develops a large web project of a social type. Social meaning people, communities, interaction and all that usual stuff. The issue is that I myself am working on something that falls into the category of social in my private time. Now the question. Is it wise to apply there under these circumstances? I think there may be issues of intellectual ownership if I develop something similar that exists or will exist in that company's work. On the other hand, the web of full of social places (even this site is one of them), many of them utilize the same ideas and move in the same direction and it seems to work for everyone. It's hard to come up with something which hasn't been tried yet by somebody else so it's all basically reuse of the commonly available ideas and experience. What I'm working on is not a functional equivalent, it's rather largely off. There may be some intersections, but on a large scale this is not an equivalent. And whatever features might coincide, they already exist everywhere on the web anyway. Also technology stacks are entirely different so the issue with directly copying out parts of the code is probably not applicable. I plan to say it up front that I'm engaged in a personal project of mine and let them see if it represents a problem for them. What do you think? Am I making things up or is there really an issue?

  • Panning a 3d viewport in 2d direction with rotated camera

    - by Noob Game Developer
    I am using below code to pan the viewport (action script 3 code using flare3d framework) _mainCamera.x-= Input3D.mouseXSpeed; _mainCamera.z+= Input3D.mouseYSpeed; Where as Input3D.mouse[X|Y]Speed gives the displacement of the mouse on the X/Y axis starting from the position of the last frame. This works perfect if my camera is not rotated. However, if I rotate the camera (x by 30, y by 60) and pan the camera then it goes wrong. Which is actually correctly panning according to the code. But this is not desired and I know I need to do some math to get the correct x/y which I am not aware of it. Can some one help me achieving it? Update: I am getting an Idea but I am not sure how to do it :( Get the mouseX/Y deltas (xd,yd) Get the current camera coords (pos3d) Convert to screen coords (pos2d) Add deltas to screen coords (pos2d+ (xd,yd)) Convert above coords to 3d coords

  • Can you work for the big (Google, Microsoft, Facebook etc.) without getting too much involved?

    - by Developer Art
    Having seen people talking about interviewing and working for the big companies, I keep wondering how much are you expected to actually get involved in there. 1) That's because I keep seeing folks from Google and Microsoft and others writing in forums, blogging, tweeting, speaking at conferences and seemingly doing this on the 24/7/365 basis from their office, apartment, hotel and even plane. Are you really expected to commit that much if you come to work for them? Do they want you to think about your work while you're eating, sleeping, taking a shower, making love and so on? Can you in fact "switch off" at five and go home forgetting everything? Perhaps you have a hobby, family life, kids, friends, personal projects anyone? Is it so that if you work for the big then you're expected not to have any life outside of the company? You can't develop own projects, have own clients and just have another life? 2) One other thing is the work contracts the big use. I've heard for instance that when you join Microsoft you need to provide a list of projects you're currently working on and after that anything new you'll come up with during your employment automatically belongs to the company. Are all of the big doing this? Can you deny signing a contract until such clause is removed or with the big it is "take it or leave it" because the legal department won't accept any change? Can you make them write the contract in that manner that they step away from anything you've developed in your private time? Of all the big I have only been at SAP during my internship. Lately while browsing through the old papers I've found my old contact which stipulated they owned everything I developed or invented during my employment, which I would never have signed these days. On a side note I don't think I would return to SAP since I remember most people there were clueless and provided the impression they were simply sitting out their years waiting for the retirement. But anyway, what do the other big put in their contracts? How far do you get involved when you go working for the big? Or perhaps fully committed with your body and soul? P.S. I'm not planning to join any of them I'm just curious.

  • Avoid pagination pages from appearing higher than real content in SERPS

    - by WordPress Developer
    I have a gallery-type website that has about 20k of pages and naturally it uses pagination. However, sometimes /page/2 appears higher in search results than /post/201339 for example. I'd like to give emphasis to the actual content (posts, videos, whatever the site is about) and not on pages that merely list this content in a paginated matter. What is the best way to avoid this issue? Maybe a NOINDEX,FOLLOW meta tag on the paginated pages?

  • my Search method is coming up with all nulls

    - by Epic.Distortion
    Let me give a quick explanation. I took a 5 week course through a company on Java in July. They covered basic stuff, like console app, crud operations, mysql, and n-tier architecture. Since the course ended I didn't use it much because I went back to work, and other medical reasons surfaced....blah blah. I was told by the company to make a simple program to reflect what I learned. Turns out I retained very little. I decided to make a video game starage program. It would be used to stare your video games so you wouldn't have to search your bookcase(or how ever you store your games.) It is a basic console app using the crud operations with MYSQL. I can't get my search function to actually work. I have 2 layers a Presentation layer and a Logic layer. The search method allows them to search for a game by the title. when i bring run the program and use Search it only displays the title and the rest is null. here is my Presentation layer: private static Games SearchForGame() { Logic aref = new Logic(); Games g = new Games(); Scanner scanline = new Scanner(System.in); System.out.println("Please enter the name of the game you wish to find:"); g.setTitle(scanline.nextLine()); aref.SearchGame(); System.out.println(); System.out.println("Game Id: " + g.getGameId()); System.out.println("Title: " + g.getTitle()); System.out.println("Rating: " + g.getRating()); System.out.println("Platform: "+ g.getPlatform()); System.out.println("Developer: "+ g.getDeveloper()); return g; } and here is my logic layer public Games SearchGame() { Games g = new Games(); try { Class.forName(driver).newInstance(); Connection conn = DriverManager.getConnection(url+dbName,userName,password); java.sql.PreparedStatement statement = conn.prepareStatement("SELECT GameId,Title,Rating,Platform,Developer FROM games WHERE Title=?"); statement.setString(1, g.getTitle()); ResultSet rs = statement.executeQuery(); while(rs.next()){ g.setGameId(rs.getInt("GameId")); g.setTitle(rs.getString("Title")); g.setRating(rs.getString("Rating")); g.setPlatform(rs.getString("Platform")); g.setDeveloper(rs.getString("Developer")); statement.executeUpdate(); } } catch (Exception e) { e.printStackTrace(); } return g; } here is also my last results Please enter the name of the game you wish to find: Skyrim Game Id: 0 Title: Skyrim Rating: null Platform: null Developer: null any help would be greatly appreciated and thanks in advance EDIT: here is my code for my games class public class Games { public int GameId; public String Title; public String Rating; public String Platform; public String Developer; public int getGameId() { return GameId; } public int setGameId(int gameId) { return GameId = gameId; } public String getTitle() { return Title; } public String setTitle(String title) { return Title = title; } public String getRating() { return Rating; } public void setRating(String rating) { Rating = rating; } public String getPlatform() { return Platform; } public void setPlatform(String platform) { Platform = platform; } public String getDeveloper() { return Developer; } public void setDeveloper(String developer) { Developer = developer; } }

  • You are probably NOT a SharePoint Development Expert if&hellip;

    - by Mark Rackley
    So, all you aspiring SharePoint experts out there (especially those of you who put “expert” in your resumes).  It’s time for a cold cool splash of reality. More than likely you are NOT an expert (I know I’m not). Yes, you may have some expertise in certain aspects in SharePoint (it’s questionable if I have THAT some days), but make sure you’ve got the basics down before you start throwing that word “expert” around. I know that it becomes frustrating to those looking to hire SharePoint people and having to sift through all the resumes of those who think very highly of themselves and their skills only to find those gaping holes in common best practices. I’m much more willing to hire a decent dev who KNOWS they are not an expert than to hire a decent+ dev who THINKS they are an expert.  So… I’ve compiled a small reality check for you SharePoint Devs. and a “red flag” check for those of you wishing to hire a SharePoint developer. If any of these apply to you, you are probably not a SharePoint Development Expert. You are not a SharePoint Development Expert if you manually copy your DLLs Seriously, I don’t care if you write the best code in the world. If you are manually copying files to each web front end you are NOT a SharePoint Development expert. Yes, I realize the admins are generally the ones who do the actual deployments, but if you don’t know how to create solution packages for your admins, you are going to end up doing more damage than good some day. There are TONS of tools out there to help generate deployable solutions for you. You have ZERO excuse. You are not a SharePoint Development expert if you can’t tell me the main artifacts of a solution package Directly related to the first one. If you don’t know what the Manifest, DDF, WSP, and Feature files are and how they are used in a solution package, you are NOT a SharePoint development expert. I’m not asking you to be able to write them all from scratch (heck, I can’t even do that), but you MUST know what they are and how to tweak them if necessary. You are not a SharePoint Development expert if you don’t know what a Content Type or a Site Column is You would be absolutely amazed at how many “Expert” SharePoint Developers have NEVER EVER created a Content Type or Site Column or even know what they are. I mean, why would you ever want to create those when you can just do everything as a custom list or custom field? right???? (that’s sarcasm). You also need to know how to package a Content Type and a Site Column into a deployable package by the way. You are not a SharePoint Development expert if you have not created at least one Web Part, Workflow, Timer Job, and Event Handler. If you haven’t written at least one of each, you don’t fully understand what they do or their limitations. Again, I expect NO ONE to be able to write these things blind. I think the last time I wrote an application from scratch without copying and pasting from another project I had done before was back in 1994? Seriously, coding is like a Sour Dough starter, you get it from someone else and keep adding to it. You are not a SharePoint Development expert if you don’t know how to properly dispose of objects Another biggie with zero excuse for getting it wrong. It is so well known that you must dispose of your SPWeb and SPSite objects that if you aren’t doing it then you are not an expert. Heck, if you utilize “using” when handling SPWeb and SPSite objects and don’t realize that it disposes of those objects for you, then you are not a SharePoint Development expert. You are not a SharePoint Development expert if you do not know how to properly elevate privileges Just one of those development basics that any decent SharePoint Developer has got to have down and understand how and why it’s used You are not a SharePoint Development expert if you don’t know all of the development options available to SharePoint and when they should be used Okay… so all you hard core .NET SharePoint dev geeks take a moment to listen. You may be the most top not SharePoint .NET developer in the world, but if you are opening Visual Studio to solve every problem in SharePoint, then you are NOT a SharePoint development expert. The SharePoint developer’s tool kit is growing every day with tools like Visual Studio, Data View Web Parts, XSL, jQuery, SPServices, etc. etc… If you don’t have the ability to at least recognize that “hey, you can basically do the same thing here but just dropping in Easy Tabs instead of writing some weird web part” then you are NOT a SharePoint Development expert AND you are doing a huge disservice to your clients and customers. You are probably NOT a SharePoint Development expert if you call yourself an Expert So, truth telling time. I’m not an expert. There, I said it. I feel so much better. Now, I realize the word “expert” has been used with my name before, but I am quick to point out that I KNOW the experts and know that they will help me if I need it, but I’m not an expert in all things SharePoint. The minute you take on that moniker you are setting yourself up for a fall. It’s too big, there’s too much to know, and there’s WAY too much you can do wrong. You are not a SharePoint Development expert if you are not involved in the community I expect to get the most flack for this one, but it’s always a huge red flag for me when someone says they are an expert and has ZERO knowledge of the SharePoint community. The SharePoint community is ABSOLUTELY CRITICAL to be an effective SharePoint developer, admin, architect, power user or whatever the heck you are!! The community keeps you sane, tells you when you are NOT using a best practice, recommends the best practice, and even knows when Microsoft is giving you the wrong information (*gasp* it does happen). If you can’t tell me who you are following on twitter, who's blog you read, what conferences you attend, or name the experts who you monitor to make sure you are not doing something stupid, then you are probably doing something stupid. Again, not asking you to be a speaker, blogger, or the least bit extroverted but you should be at LEAST stalking the experts. So… what’s the point? So… yeah… what’s my point in all this. Well, first of all let me point out that this is by far not a finished list and I could come up with a LOT more specific “deep dive” questions, but these should be high enough level that even non experts can recognize and ask them. If you have some common ones you run into let me know and add them in the comments below. Also, keep in mind I’m not saying you as a developer HAVE to know EVERYTHING, but you DO need to know what you don’t know and proudly and honestly state “I don’t know, but I’ll learn and find out”.  Those of us hiring SharePoint developers and know and have a passion for SharePoint are not looking for that elusive “expert” who knows everything. We are looking for someone who “gets it”, has a similar passion, great attitude, an understanding that they DON’T know everything, and a desire to do it right.  I would bet money that most SharePoint development disasters happen because of “experts” who think they know everything rather than the developer who is cautious and knows he doesn’t. Lastly, I know there’s a raging debate over what a “SharePoint Developer” is (I should know, as I keep bringing it up). So, obviously this blog post is more closely tied to the .NET side of SharePoint development and less towards the client side, middle tier, or whatever you want to call it. So, let’s please not get that argument going here as well…  Thanks

  • Now Available &ndash; Windows Azure SDK 1.6

    - by Shaun
    Microsoft has just announced the Windows Azure SDK 1.6 and the Windows Azure Tools for Visual Studio 1.6. Now people can download the latest product through the WebPI. After you downloaded and installed the SDK you will find that The SDK 1.6 can be stayed side by side with the SDK 1.5, which means you can still using the 1.5 assemblies. But the Visual Studio Tools would be upgraded to 1.6. Different from the previous SDK, in this version it includes 4 components: Windows Azure Authoring Tools, Windows Azure Emulators, Windows Azure Libraries for .NET 1.6 and the Windows Azure Tools for Microsoft Visual Studio 2010. There are some significant upgrades in this version, which are Publishing Enhancement: More easily connect to the Windows Azure when publish your application by retrieving a publish setting file. It will let you configure some settings of the deployment, without getting back to the developer portal. Multi-profiles: The publish settings, cloud configuration files, etc. will be stored in one or more MSBuild files. It will be much easier to switch the settings between vary build environments. MSBuild Command-line Build Support. In-Place Upgrade Support.   Publishing Enhancement So let’s have a look about the new features of the publishing. Just create a new Windows Azure project in Visual Studio 2010 with a MVC 3 Web Role, and right-click the Windows Azure project node in the solution explorer, then select Publish, we will find the new publish dialog. In this version the first thing we need to do is to connect to our Windows Azure subscription. Click the “Sign in to download credentials” link, we will be navigated to the login page to provide the Live ID. The Windows Azure Tool will generate a certificate file and uploaded to the subscriptions those belong to us. Then we will download a PUBLISHSETTINGS file, which contains the credentials and subscriptions information. The Visual Studio Tool will generate a certificate and deployed to the subscriptions you have as the Management Certificate. The VS Tool will use this certificate to connect to the subscription in the next step. In the next step, I would back to the Visual Studio (the publish dialog should be stilling opened) and click the Import button, select the PUBLISHSETTINGS file I had just downloaded. Then all my subscriptions will be shown in the dropdown list. Select a subscription that I want the application to be published and press the Next button, then we can select the hosted service, environment, build configuration and service configuration shown in the dialog. In this version we can create a new hosted service directly here rather than go back to the developer portal. Just select the <Create New …> item in the hosted service. What we need to do is to provide the hosted service name and the location. Once clicked the OK, after several seconds the hosted service will be established. If we went to the developer portal we will find the new hosted service in my subscription. a) Currently we cannot select the Affinity Group when create a new hosted service through the Visual Studio Publish dialog. b) Although we can specify the hosted service name and DNS prefixing through the developer portal, we cannot do so from the VS Tool, which means the DNS prefixing would be the same as what we specified for the hosted service name. For example, we specified our hosted service name as “Sdk16Demo”, so the public URL would be http://sdk16demo.cloudapp.net/. After created a new hosted service we can select the cloud environment (production or staging), the build configuration (release or debug), and the service configuration (cloud or local). And we can set the Remote Desktop by check the related checkbox as well. One thing should be note is that, in this version when we set the Remote Desktop settings we don’t need to specify a certificate by default. This is because the Visual Studio will generate a new certificate for us by default. But we can still specify an existing certificate for RDC, by clicking the “More Options” button. Visual Studio Tool will create another certificate for the Remote Desktop connection. It will NOT use the certificate that managing the subscription. We also can select the “Advanced Settings” page to specify the deployment label, storage account, IntelliTrace and .NET profiling information, etc.. Press Next button, the dialog will display all settings I had just specified and it will save them as a new profile. The last step is to click the Publish button. Since we enabled the Remote Desktop feature, the first step of publishing was uploading the certificate. And then it will verify the storage account we specified and upload the package, then finally created the website in Windows Azure.   Multi-Profiles After published, if we back to the Visual Studio we can find a AZUREPUBXML file under the Profiles folder in the Azure project. It includes all settings we specified before. If we publish this project again, we can just use the current settings (hosted service, environment, RDC, etc.) from this profile without input them again. And this is very useful when we have more than one deployment settings. For example it would be able to have one AZUREPUBXML profile for deploying to testing environment (debug building, less roles with RDC and IntelliTrace) and one for production (release building, more roles but without IntelliTrace).   In-Place Upgrade Support Let’s change some codes in the MVC pages and click the Publish menu from the azure project node. No need to specify any settings,  here we can use the pervious settings by loading the azure profile file (AZUREPUBXML). After clicked the Publish button the VS Tool brought a dialog to us to indicate that there’s a deployment available in the hosted service environment, and prompt to REPLACE it or not. Notice that in this version, the dialog tool said “replace” rather than “delete”, which means by default the VS Tool will use In-Place Upgrade when we deploy to a hosted service that has a deployment already exist. After click Yes the VS Tool will upload the package and perform the In-Place Upgrade. If we back to the developer portal we can find that the status of the hosted service was turned to “Updating…”. But in the previous SDK, it will try to delete the whole deployment and publish a new one.   Summary When the Microsoft announced the features that allows the changing VM size via In-Place Upgrade, they also mentioned that in the next few versions the user experience of publishing the azure application would be improved. The target was trying to accomplish the whole publish experience in Visual Studio, which means no need to touch developer portal any more. In the SDK 1.6 we can see from the new publish dialog, as a developer we can do the whole process, includes creating hosted service, specifying the environment, configuration, remote desktop, etc. values without going back the the developer portal.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • "Java & XML" job title

    - by Aspiring developer
    When people say they are a "Java & XML" developer, what do they mean? Are they saying they create XML data to be used in applications, or they use XML to configure a framework like Spring or Hibernate? What other ways are there to use XML in a Java application?

  • simple Stata program

    - by Cyrus S
    I am trying to write a simple program to combine coefficient and standard error estimates from a set of regression fits. I run, say, 5 regressions, and store the coefficient(s) and standard error(s) of interest into vectors (Stata matrix objects, actually). Then, I need to do the following: Find the mean value of the coefficient estimates. Combine the standard error estimates according to the formula suggested for combining results from "multiple imputation". The formula is the square root of the formula for "T" on page 6 of the following document: http://bit.ly/b05WX3 I have written Stata code that does this once, but I want to write this as a function (or "program", in Stata speak) that takes as arguments the vector (or matrix, if possible, to combine multiple estimates at once) of regression coefficient estimates and the vector (or matrix) of corresponding standard error estimates, and then generates 1 and 2 above. Here is the code that I wrote: (breg is a 1x5 vector of the regression coefficient estimates, and sereg is a 1x5 vector of the associated standard error estimates) mat ones = (1,1,1,1,1) mat bregmean = (1/5)*(ones*breg’) scalar bregmean_s = bregmean[1,1] mat seregmean = (1/5)*(ones*sereg’) mat seregbtv = (1/4)*(breg - bregmean#ones)* (breg - bregmean#ones)’ mat varregmi = (1/5)*(sereg*sereg’) + (1+(1/5))* seregbtv scalar varregmi_s = varregmi[1,1] scalar seregmi = sqrt(varregmi_s) disp bregmean_s disp seregmi This gives the right answer for a single instance. Any pointers would be great! UPDATE: I completed the code for combining estimates in a kXm matrix of coefficients/parameters (k is the number of parameters, m the number of imputations). Code can be found here: http://bit.ly/cXJRw1 Thanks to Tristan and Gabi for the pointers.
