This has nothing to do with Oracle Entitlement Server (OES) but is the ability to group resources into permission sets so they can be granted with a single grant statement. For example, as good practices when organizing your projects, you may have grouped your bounded task flows by functionality and responsibility in sub folders under the WEB-INF directory. If one of the folders holds bounded task flows that are accessible to all authenticated users, you may create an entitlement grant allAuthUserBTF and select all bounded task flows that are accessible for authenticated users as resources. You can then grant allAuthUserBTF to the authenticated-role so that with only a single grant statement all selected bounded task flows are protected.

• Hiding the Flash Message After a Time Delay

  - by Madhan ayyasamy

  Hi Friends,The flash hash is a great way to provide feedback to your users.Here is a quick tip for hiding the flash message after a period of time if you don’t want to leave it lingering around.First, add this line to the head of your layout to ensure the prototype and script.aculo.us javascript libraries are loaded:Next, add the following to either your layout (recommended), your view templates or a partial depending on your needs. I usually add this to a partial and include the partial in my layouts. "flash", :id = flash_type % "text/javascript" do % setTimeout("new Effect.Fade('');", 10000); This will wrap the flash message in a div with class=‘flash’ and id=‘error’, ‘notice’ or ‘warn’ depending on the flash key specified.The value ‘10000’ is the time in milliseconds before the flash will disappear. In this case, 10 seconds.This function looks pretty good and little javascript stunts like this can help make your site feel more professional. It’s also worth bearing in mind though, not everybody can see well or read as quickly as others so this may not be suitable for every application.Update:As Mitchell has pointed out (see comments below), it may be better to set the flash_type as the div class rather than it’s id. If there is the possibility that you’ll be showing more than one flash message per page, setting the flash_type as the div id will result in your HTML/XHTML code becoming invalid because the unique intentifier will be used more than once per page.Here is a slightly more complex version of the method shown above that will hide all divs with class ‘flash’ after a time delay, achieving the same effect and also ensuring your code stays valid with more than one flash message! "flash #{flash_type}" % "text/javascript" do % setTimeout("$$('div.flash').each(function(flash){ flash.hide();})", 10000); In this example, the div id is not set at all. Instead, each flash div will have class “div” and also class of the type of flash message (“error”, “warning” etc.).Have a Great Day..:)

• VPN Connects with local access only

  - by user20102

  I have Windows Server 2008 and I have set up a VPN. When a user logs into their VPN they can not view the internet. It comes up as local access only on the the client PC. On the server when I go to the Network And Sharing Centre it displays (Network) with local and internet below it has the RAS Dial-in interface and it displays as local only there as well. I want all users that connect to my VPN to have internet access (full access). If anyone can help me it would be appreciated. Also I've activated dial-in properties and I've done it via policy who can access the VPN and internet. It still doesn't work, but there is a connection but just local only. Thanks

• PDF rendering issue os OSX

  - by 2Ti

  I came across some very odd rendering when trying to view a PDF file that needed to print out. I was wondering anyone has come across a similar problem before or has any ideas as to what might be causing this. PDF when viewed on OSX 10.7.4 - Preview version 6.0. I've tried opening the file in Skim but that doesn't work either. PDF as it should be, and as Chrome renders it in browser, but not if I download it onto my machine. Illustrator complains about "an unknown imaging construct" when I open the file, but renders it fine nevertheless, Photoshop doesn't have any problems either.

• How do I get google to see keywords on a one page web application site?

  - by David

  I'm going to have to link to the web site to explain this, http://www.diagram.ly, it's a free service, so I hope this doesn't break advertising rules. Basically, it's a one page web application, I don't want to create a web site for it. Some background text loads and if JavaScript is enabled, the web application itself then loads. The problem is that Google only seems to be picking up the title of the page and the text on the footer, so the site only appear on Google search for very limited text (based on the title and meta description mostly). I was hoping that search engines would pick up on the background text and index that. The text is factual, not keyword stuffed. Yahoo seems to pick up the text, just not Google. Does anyone have any experience of how Google would view such a site and where I could put the text for a better result? Edit I should mention that Google Webmaster Tools lists the site keywords as "Component, diagramly, feed, mxgraph, share and twitter". Basically the footer and little else.

• Issue 55 - Skin Object Tokens, Optimized Control Panel, OWS Validation and Security, RAD

  April 2010 Welcome to Issue 55 of DNN Creative Magazine In this issue we focus on the new Skin Object token method introduced in DotNetNuke 5 for adding tokens into a DotNetNuke skin. A Skin Object Token is a web user control which covers skin elements such as the logo, menu, search, login links, date, copyright, languages, links, banners, privacy, terms of use, etc. Following this we demonstrate how to install and use two Advanced DotNetNuke Admin Control Panels which are available for free from Oliver Hine. These control panels provide an optimized version of the admin control panel to improve performance and page load times, as well as a ribbon bar control panel which adds additional features. Next, we continue the Open Web Studio tutorials, this month we demonstrate some very advanced techniques for building a car parts application in Open Web Studio. Throughout the tutorial we cover form input, validation, how to use dependant drop down lists, populating checkbox lists and introduce a new concept of data level security. Data level security allows you to control which data a user can access within a module. To finish, we have part five of the "How to Build a News Application with DotNetMushroom Rapid Application Developer (RAD)" article, where we demonstrate how to implement paging. This issue comes complete with 14 videos. Skinning: Skin Object Tokens for DotNetNuke 5 (8 videos - 64mins) Free Module: Advanced Optimized Control Panel by Oliver Hine (1 video - 11mins) Module Development Series: Form Validation, Dependant Drop Downs and Data Level Security in OWS (5 videos - 44mins) How to Implement Paging with DotNetMushroom RAD View issue 55 to download all of the videos in one zip file DNN Creative Magazine for DotNetNuke Web Designers Covering DotNetNuke module video reviews, video tutorials, mp3 interviews, resources and web design tips for working with DotNetNuke.

• Managing Scripts in Oracle SQL Developer

  - by thatjeffsmith

  You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

• Java web app, with plugin framework and ability to connect to source for updates

  - by lessthancommon

  I've searched all around for some good sources, but either have been searching for the wrong keywords, or I'm just missing something. I'm looking to redevelop a web app I've been using for some time now. Many parts are out of date, and we're constantly throwing in little hacks to attempt to give it new life. So what I'd like to do is re-engineer it from the ground up, built on some sort of plug-in framework. Before I continue, I'm more or less an intermediate Java programmer. In some ways, I'm hoping to use this project as a big learning experience. I've read a lot about OSGi, and it seems that's the most complete framework. Ideally, I would like an end result web app which I can run one instance as my hosting environment, and other instances can connect to it to grab new and updated plug-ins. Eventually I'll want to lock down these plug-ins based on some undecided criteria of who can get them (basically some will simply be updates, others will provide new functionality and should be "purchased" through an external system). But that will probably be handled in a later phase. There should be an administration view for managing bundles in a hot environment (looking to avoid having to restart the server for an update). I know all these things are possible, I'm just trying to find some good resources for reference. All the OSGi tutorials I'm finding seem to be too simplistic. If anyone here can guide me in the right direction on any or all of the items I'm looking for, it would be much appreciated. Also, this is my first post, so I'll take any comments/criticisms about the content of my post. Thanks!

• Code Reuse is (Damn) Hard

  - by James Michael Hare

  Being a development team lead, the task of interviewing new candidates was part of my job.  Like any typical interview, we started with some easy questions to get them warmed up and help calm their nerves before hitting the hard stuff. One of those easier questions was almost always: “Name some benefits of object-oriented development.”  Nearly every time, the candidate would chime in with a plethora of canned answers which typically included: “it helps ease code reuse.”  Of course, this is a gross oversimplification.  Tools only ease reuse, its developers that ultimately can cause code to be reusable or not, regardless of the language or methodology. But it did get me thinking…  we always used to say that as part of our mantra as to why Object-Oriented Programming was so great.  With polymorphism, inheritance, encapsulation, etc. we in essence set up the concepts to help facilitate reuse as much as possible.  And yes, as a developer now of many years, I unquestionably held that belief for ages before it really struck me how my views on reuse have jaded over the years.  In fact, in many ways Agile rightly eschews reuse as taking a backseat to developing what's needed for the here and now.  It used to be I was in complete opposition to that view, but more and more I've come to see the logic in it.  Too many times I've seen developers (myself included) get lost in design paralysis trying to come up with the perfect abstraction that would stand all time.  Nearly without fail, all of these pieces of code become obsolete in a matter of months or years. It’s not that I don’t like reuse – it’s just that reuse is hard.  In fact, reuse is DAMN hard.  Many times it is just a distraction that eats up architect and developer time, and worse yet can be counter-productive and force wrong decisions.  Now don’t get me wrong, I love the idea of reusable code when it makes sense.  These are in the few cases where you are designing something that is inherently reusable.  The problem is, most business-class code is inherently unfit for reuse! Furthermore, the code that is reusable will often fail to be reused if you don’t have the proper framework in place for effective reuse that includes standardized versioning, building, releasing, and documenting the components.  That should always be standard across the board when promoting reusable code.  All of this is hard, and it should only be done when you have code that is truly reusable or you will be exerting a large amount of development effort for very little bang for your buck. But my goal here is not to get into how to reuse (that is a topic unto itself) but what should be reused.  First, let’s look at an extension method.  There’s many times where I want to kick off a thread to handle a task, then when I want to reign that thread in of course I want to do a Join on it.  But what if I only want to wait a limited amount of time and then Abort?  Well, I could of course write that logic out by hand each time, but it seemed like a great extension method: 1: public static class ThreadExtensions 2: { 3: public static bool JoinOrAbort(this Thread thread, TimeSpan timeToWait) 4: { 5: bool isJoined = false; 6:  7: if (thread != null) 8: { 9: isJoined = thread.Join(timeToWait); 10:  11: if (!isJoined) 12: { 13: thread.Abort(); 14: } 15: } 16: return isJoined; 17: } 18: } 19:  When I look at this code, I can immediately see things that jump out at me as reasons why this code is very reusable.  Some of them are standard OO principles, and some are kind-of home grown litmus tests: Single Responsibility Principle (SRP) – The only reason this extension method need change is if the Thread class itself changes (one responsibility). Stable Dependencies Principle (SDP) – This method only depends on classes that are more stable than it is (System.Threading.Thread), and in itself is very stable, hence other classes may safely depend on it. It is also not dependent on any business domain, and thus isn't subject to changes as the business itself changes. Open-Closed Principle (OCP) – This class is inherently closed to change. Small and Stable Problem Domain – This method only cares about System.Threading.Thread. All-or-None Usage – A user of a reusable class should want the functionality of that class, not parts of that functionality.  That’s not to say they most use every method, but they shouldn’t be using a method just to get half of its result. Cost of Reuse vs. Cost to Recreate – since this class is highly stable and minimally complex, we can offer it up for reuse very cheaply by promoting it as “ready-to-go” and already unit tested (important!) and available through a standard release cycle (very important!). Okay, all seems good there, now lets look at an entity and DAO.  I don’t know about you all, but there have been times I’ve been in organizations that get the grand idea that all DAOs and entities should be standardized and shared.  While this may work for small or static organizations, it’s near ludicrous for anything large or volatile. 1: namespace Shared.Entities 2: { 3: public class Account 4: { 5: public int Id { get; set; } 6:  7: public string Name { get; set; } 8:  9: public Address HomeAddress { get; set; } 10:  11: public int Age { get; set;} 12:  13: public DateTime LastUsed { get; set; } 14:  15: // etc, etc, etc... 16: } 17: } 18:  19: ... 20:  21: namespace Shared.DataAccess 22: { 23: public class AccountDao 24: { 25: public Account FindAccount(int id) 26: { 27: // dao logic to query and return account 28: } 29:  30: ... 31:  32: } 33: } Now to be fair, I’m not saying there doesn’t exist an organization where some entites may be extremely static and unchanging.  But at best such entities and DAOs will be problematic cases of reuse.  Let’s examine those same tests: Single Responsibility Principle (SRP) – The reasons to change for these classes will be strongly dependent on what the definition of the account is which can change over time and may have multiple influences depending on the number of systems an account can cover. Stable Dependencies Principle (SDP) – This method depends on the data model beneath itself which also is largely dependent on the business definition of an account which can be very inherently unstable. Open-Closed Principle (OCP) – This class is not really closed for modification.  Every time the account definition may change, you’d need to modify this class. Small and Stable Problem Domain – The definition of an account is inherently unstable and in fact may be very large.  What if you are designing a system that aggregates account information from several sources? All-or-None Usage – What if your view of the account encompasses data from 3 different sources but you only care about one of those sources or one piece of data?  Should you have to take the hit of looking up all the other data?  On the other hand, should you have ten different methods returning portions of data in chunks people tend to ask for?  Neither is really a great solution. Cost of Reuse vs. Cost to Recreate – DAOs are really trivial to rewrite, and unless your definition of an account is EXTREMELY stable, the cost to promote, support, and release a reusable account entity and DAO are usually far higher than the cost to recreate as needed. It’s no accident that my case for reuse was a utility class and my case for non-reuse was an entity/DAO.  In general, the smaller and more stable an abstraction is, the higher its level of reuse.  When I became the lead of the Shared Components Committee at my workplace, one of the original goals we looked at satisfying was to find (or create), version, release, and promote a shared library of common utility classes, frameworks, and data access objects.  Now, of course, many of you will point to nHibernate and Entity for the latter, but we were looking at larger, macro collections of data that span multiple data sources of varying types (databases, web services, etc). As we got deeper and deeper in the details of how to manage and release these items, it quickly became apparent that while the case for reuse was typically a slam dunk for utilities and frameworks, the data access objects just didn’t “smell” right.  We ended up having session after session of design meetings to try and find the right way to share these data access components. When someone asked me why it was taking so long to iron out the shared entities, my response was quite simple, “Reuse is hard...”  And that’s when I realized, that while reuse is an awesome goal and we should strive to make code maintainable, often times you end up creating far more work for yourself than necessary by trying to force code to be reusable that inherently isn’t. Think about classes the times you’ve worked in a company where in the design session people fight over the best way to implement a class to make it maximally reusable, extensible, and any other buzzwordable.  Then think about how quickly that design became obsolete.  Many times I set out to do a project and think, “yes, this is the best design, I can extend it easily!” only to find out the business requirements change COMPLETELY in such a way that the design is rendered invalid.  Code, in general, tends to rust and age over time.  As such, writing reusable code can often be difficult and many times ends up being a futile exercise and worse yet, sometimes makes the code harder to maintain because it obfuscates the design in the name of extensibility or reusability. So what do I think are reusable components? Generic Utility classes – these tend to be small classes that assist in a task and have no business context whatsoever. Implementation Abstraction Frameworks – home-grown frameworks that try to isolate changes to third party products you may be depending on (like writing a messaging abstraction layer for publishing/subscribing that is independent of whether you use JMS, MSMQ, etc). Simplification and Uniformity Frameworks – To some extent this is similar to an abstraction framework, but there may be one chosen provider but a development shop mandate to perform certain complex items in a certain way.  Or, perhaps to simplify and dumb-down a complex task for the average developer (such as implementing a particular development-shop’s method of encryption). And what are less reusable? Application and Business Layers – tend to fluctuate a lot as requirements change and new features are added, so tend to be an unstable dependency.  May be reused across applications but also very volatile. Entities and Data Access Layers – these tend to be tuned to the scope of the application, so reusing them can be hard unless the abstract is very stable. So what’s the big lesson?  Reuse is hard.  In fact it’s damn hard.  And much of the time I’m not convinced we should focus too hard on it. If you’re designing a utility or framework, then by all means design it for reuse.  But you most also really set down a good versioning, release, and documentation process to maximize your chances.  For anything else, design it to be maintainable and extendable, but don’t waste the effort on reusability for something that most likely will be obsolete in a year or two anyway.

• How do I create a 2.5d parallax effect?

  - by Nikolay Dyankov

  I have a decent background in 3D graphics and programming, but I'm new to game development. I'm currently exploring different possibilities and I really want to make an RPG game. I was thinking about classic 2D isometric view, but I really love how Diablo 2 looks and feels to play. My question is - how can I achieve Diablo 2's parallax effect? Everything looks hand drawn with baked lights and shadows and looks awesome, but when you move around you notice some perspective. For example, let's say that I drew a big hall with columns in Photoshop with an orthographic perspective (classic pixel art style, just parallel lines). How would I give parallax effect to this scene when the character moves around? If I use camera-facing sprites for everything it would probably look OK in the distance, but it would be really fake when a character comes close to a column (cylinder) for example. Any suggestions? How did Blizzard make the parallax effect in Diablo 2? See this screenshot: http://guidesmedia.ign.com/guides/10629/images/act2tombs.jpg

• Configure IE to use MS Word Viewer as .doc viewer on Citrix server with Office installed

  - by Adam Towne

  We have a small number of citrix servers that all have office installed. Only a small subset of users have access to office. Everyone is set to open office documents with the free viewers on the Citrix servers. We control access to office through NTFS permissions. We now have a large number of users who need to be able to view office documents from a webpage. Opening office files normally works fine. When users open the office documents from the link in a webpage, it ignores the file associations and attempts to open the document with the full office program. How can I change the program that IE uses to open office documents, or how can I force it to use the file associations I set in the operating system?

• EVENT RECAP: Oracle Health Sciences Conference

  - by cwarticki

  Monaco served as an intense location for this year's Oracle Health Sciences User Group conference.  It was a "Grand Prix" event with nearly 200 attendees from all over the world.  In a country famous for high performance race cars, luxury super yachts and lifestyles of the rich & famous, the conference was very Ellison-esque. I think the Superyachts were being paired with Exadata. The OSHUG staff were fantastic . Robin and Taylor (pictured left) from Drohan Management took care of all the details and were wonderful to get to know. I met with some real Oracle loyalists.  Stan Sachar,  I.T. Manager for Westat, and the Focus Group co-chair for Admin Configuration Mgmt (ACM).  Westat was an early adopter of Oracle Clinical for clinical trial projects with installations in 1997-98.  I had a chance to talk with Stan during the reception and he is an Oracle advocate and evangelist. He's invested in his career in using Oracle products. (Stan Sachar pictured right with Dick Wolnick from Oracle, on left) I also met with Mirco Becker from Grunenthal Gmbh.  He's been working with the Argus product for over 6 years.  He's a big user of Oracle Support. Mirco attended my support best practices session and was actively engaged and asked several questions.  He's excited to adopt those best practices and work more efficiently and effectively with Support. Finally, I thank the many who attended my session.  I admit, the beautiful weather and view of the ocean was a distraction, but nonetheless my mission was to provide you with all the necessary support resources for Health Sciences users. You will find a copy of my presentation on the OSHUG website. Bon Voyage Monaco.  Thanks for the memories.  I'll see everyone next year, in Miami. -Chris WartickiGlobal Customer Management

• Google Chrome Automatic Page Load

  - by WDC

  Google Chrome keeps loading the second page of certain websites which is helpful on sites like Netflix so that instead of clicking on a link for page 2, I can just continue scrolling down and it'll automatically have the next page ready for me. But on online clothing sites, it just gets backed up loading all the next pages, misplacing links and loading the next page so that it actually replaces the page I'm trying to view literally every millisecond. Considering clothing sites generally have upwards of 20 to 200 pages of clothing, this is really annoying since Chrome tries to load all of them. How do I turn off the automatic page load???

• Kindle 2 and PDFs in landscape

  - by doronkatz

  Hi guys, I am looking at getting a Kindle 2, read a lot about the PDF support (or lack off) and wanted to ask someone who has a kindle, a question. If you read a pdf in landscape mode, does it shrink the text to have it all in the one screen, or does it increase font size and split it into two or more pages. I have another reader, the iRiver Story and it does that, splits it into multiple pages thus making it readable. I know you can't zoom or anything like that in portrait view (i assume) I know you will say stick with iRiver, but the make of the kindle is a lot better (metallic back) and its useful to have a hybrid amazon book/pdf reader in one.

• Working with documents and SharePoint - Best practices

  - by KunaalKapoor

  Follow these simple guidelines to make collaboration using SharePoint easier:1. File Name:While it is allowed to use spaces in your filename (and maybe it seems even logical to do so), don’t use them if your file will end up (or is born on) SharePoint. When you use the “download a copy” functionality, SharePoint will replace the spaces with an “_”. This might (will) result in inconsistency when you upload the “same” file again, since SharePoint will see this as a different file (since the filename is different). I recommend using a filename with Capitalization style naming guideline. For instance: the document “Overall governance model.docx” would be named “OverallGovernanceModel.docx”Use the TITLE field in the office applications to give your document a title (and subtitle and keywords, .) The title column can be used in a view in a library. You can get to the document properties by clicking on 'Office Button/Prepare/Properties'. (Office 2007). This is metadata that is stored with the document, and will remain in the document (even if you exchange this document via e-mail, via an external hard drive). The filename cannot be longer than 128 characters. (and that is IMHO far beyond reasonable) You cannot use any of these characters: ” # % & * : < > ? \ / { | } ~ 2. Versioning:SharePoint has a built-in versioning system. You can work with major (published) versions, and minor (draft) versions. Of each of these two document types, you can store a numbers of versions that are kept. Watch out, each version is saved, not only the delta between 2 versions, and this counts to your Site Collection Quota. (Example: you have a Word document with a size of 2 MB. When you keep 5 Drafts this will result in storing (and consuming) 10 MB.So, don’t call your document “NewUserAccountProcessDRAFTv1.docx”, but “NewUserAccountProcess.docx” and use versioning setting in your library.You can enable views on your library to display the version number.You can enable the version number to be displayed in a Word document.3. Use MetadataUse metadata to assign other properties to documents, so it can be easily identified, sorted- or grouped by.

• Unity scaling instantiated GameObject at Start() doesn't "keep"

  - by Shivan Dragon

  I have a very simple scenario: A box-like Prefab which is imported from Blender automatically (I have the .blend file in the Assets folder). A script that has two public GameObject fields. In one I place the above prefab, and in the other I place a terrain object (which I've created in Unity's graphical view): public Collider terrain; public GameObject aStarCellHighlightPrefab; This script is attached to the camera. The idea is to have the Blender prefab instantiated, have the terrain set as its parent, and then scale said prefab instance up. I first did it like this, in the Start() method: void Start () { cursorPositionOnTerrain = new RaycastHit(); aStarCellHighlight = (GameObject)Instantiate(aStarCellHighlightPrefab, new Vector3(300,300,300), terrain.transform.rotation); aStarCellHighlight.name = "cellHighlight"; aStarCellHighlight.transform.parent = terrain.transform; aStarCellHighlight.transform.localScale = new Vector3(100,100,100); } and first thought it didn't work. However later I noticed that it did in fact work, in the sense where the scale was applied right at the start, but then right after the prefab instance came back to its initial scale. Putting the scale code in the Update() methods fixes it in the sense where now it stays scaled all the time: void Update () { aStarCellHighlight.transform.localScale = new Vector3(100,100,100); //... } However I've noticed that when I run this code, the object is first displayed without the scale being applied, and it takes about 5-10 seconds for the scale to happen. During this time everything works fine (like input and logging, etc). The scene is very simple, it's not like it has a lot of stuff to load or anything (there's a Ray cast from the camera on to the terrain, but that seems to happen without such delays). My (2 part) question is: Why doesn't it take the scale transform when I do it at the beginning in the Start() method. Why do I have to keep scaling it in the Update() method? Why does it take so long for the scale to "apply/show up".

• Should we be able to deploy a single package to the SSIS Catalog?

  - by jamiet

  My buddy Sutha Thiru sent me an email recently asking about my opinion on a particular nuance of the project deployment model in SQL Server Integration Services (SSIS) 2012 and I’d like to share my response as I think it warrants a wider discussion. Sutha asked: Jamie What is your take on this? http://www.mattmasson.com/index.php/2012/07/can-i-deploy-a-single-ssis-package-from-my-project-to-the-ssis-catalog/ Overnight I was talking to Matt who confirmed that they got no plans to change the deployment model. For example if we have following scenrio how do we do deploy? Sprint 1 Pkg1, 2 & 3 has been developed and deployed to UAT. Once signed off its been deployed to Live. Sprint 2 Pkg 4 & 5 been developed. During this time users raised a bug on Pkg2. We want to make the change to Pkg2 and deploy that to UAT and eventually to LIVE without releasing Pkg 4 &5. How do we do it? Matt pointed me to his blog entry which I have seen before . http://www.mattmasson.com/index.php/2012/02/thoughts-on-branching-strategies-for-ssis-projects/ Thanks Sutha My response: Personally, even though I've experienced the exact problem you just outlined, I agree with the current approach. I steadfastly believe that there should not be a way for an unscrupulous developer to slide in a new version of a package under the covers. Deploying .ispac files brings a degree of rigour to your operational processes. Yes, that means that we as SSIS developers are going to have to get better at using source control and branching properly but that is no bad thing in my opinion. Claiming to be proper "developers" is a bit of a cheap claim if we don't even do the fundamentals correctly. I would be interested in the thoughts of others who have used the project deployment model. Do you agree with my point of view? @Jamiet

• Best option for PDF viewer embedded in web app

  - by RationalGeek

  I have a web app that needs to be able to display a PDF. It needs to allow the user to page through the PDF, and my application needs to be able to know which page is currently being viewed, because other aspects of the web app will change based on the current page. Ideally it would not be dependent on the client having Adobe Reader but I could probably support that dependency. What are my best options for this? My application stack consists of ASP.NET 4 along with optionally Silverlight 5. Also, I could use something that is client-side based as well using JavaScript / HTML if such a thing exists. I found ComponentOne's offering for this and that seems like the leading candidate at this point, but I want to know if there are other options I should consider. Edit: Per Fosco's comment, converting the PDF to another format (such as HTML) might be an option, as long as I could tie back parts of the converted document to the original PDF page #s. Another note: this has to run entirely on our servers. It would not be acceptable to use a third-party service to view the PDFs.

• Takeaways From CSO Roundtable New York

  - by Naresh Persaud

  Thanks to everyone who attended the Chief Security Officer Roundtable in New York last week. We were lucky to have Dennis Brixus, CSO of McGraw-Hill  as a guest speaker. In addition, Jeff Henley, provided a board level perspective on security. Amit Jasuja discussed Oracle's security formula.  A few takeaways from Jeff's talk that were interesting: Security is a board level issue. The challenge at the board level is that boards have short attention span. The CSO needs to be vigilant in educating the board on the strategic importance of security. Every CSO needs to think about cost. The CSO has to look at the economics of security and demonstrate fiduciary responsibility. We have to think of security as a business enabler. Security is the enabler that helps us expand into new markets and connect better with our customers and partners. While the CSO can't prevent every threat, we have to expect the CSO to have a plan.
