• Is Google showing ads from other companies or WordPress plugin is injecting ads which are not mine?

  - by Hafiz

  I am using WordPress for managing my blog sort of website, and I am using an Ad Injection plugin to place my ads where I want in a post. Plugin seems very good but I saw some ads which were not from ads networks which I was using. Now I have injected Google ads leaderboard at some place but I saw advertisement from this advertiser: http://www.adroll.com/about/privacy?utm_source=evidon&utm_medium=AdChoices&utm_campaign=privacy%2Bpolicy So I want to know whether ad injecting plugin is doing some trick or Google use ads from other networks too? Let me know so I can act accordingly and all good responses will be appreciated.

• Why enumerator structs are a really bad idea

  - by Simon Cooper

  If you've ever poked around the .NET class libraries in Reflector, I'm sure you would have noticed that the generic collection classes all have implementations of their IEnumerator as a struct rather than a class. As you will see, this design decision has some rather unfortunate side effects... As is generally known in the .NET world, mutable structs are a Very Bad Idea; and there are several other blogs around explaining this (Eric Lippert's blog post explains the problem quite well). In the BCL, the generic collection enumerators are all mutable structs, as they need to keep track of where they are in the collection. This bit me quite hard when I was coding a wrapper around a LinkedList<int>.Enumerator. It boils down to this code: sealed class EnumeratorWrapper : IEnumerator<int> { private readonly LinkedList<int>.Enumerator m_Enumerator; public EnumeratorWrapper(LinkedList<int> linkedList) { m_Enumerator = linkedList.GetEnumerator(); } public int Current { get { return m_Enumerator.Current; } } object System.Collections.IEnumerator.Current { get { return Current; } } public bool MoveNext() { return m_Enumerator.MoveNext(); } public void Reset() { ((System.Collections.IEnumerator)m_Enumerator).Reset(); } public void Dispose() { m_Enumerator.Dispose(); } } The key line here is the MoveNext method. When I initially coded this, I thought that the call to m_Enumerator.MoveNext() would alter the enumerator state in the m_Enumerator class variable and so the enumeration would proceed in an orderly fashion through the collection. However, when I ran this code it went into an infinite loop - the m_Enumerator.MoveNext() call wasn't actually changing the state in the m_Enumerator variable at all, and my code was looping forever on the first collection element. It was only after disassembling that method that I found out what was going on The MoveNext method above results in the following IL: .method public hidebysig newslot virtual final instance bool MoveNext() cil managed { .maxstack 1 .locals init ( [0] bool CS$1$0000, [1] valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator CS$0$0001) L_0000: nop L_0001: ldarg.0 L_0002: ldfld valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator EnumeratorWrapper::m_Enumerator L_0007: stloc.1 L_0008: ldloca.s CS$0$0001 L_000a: call instance bool [System]System.Collections.Generic.LinkedList`1/Enumerator::MoveNext() L_000f: stloc.0 L_0010: br.s L_0012 L_0012: ldloc.0 L_0013: ret } Here, the important line is 0002 - m_Enumerator is accessed using the ldfld operator, which does the following: Finds the value of a field in the object whose reference is currently on the evaluation stack. So, what the MoveNext method is doing is the following: public bool MoveNext() { LinkedList<int>.Enumerator CS$0$0001 = this.m_Enumerator; bool CS$1$0000 = CS$0$0001.MoveNext(); return CS$1$0000; } The enumerator instance being modified by the call to MoveNext is the one stored in the CS$0$0001 variable on the stack, and not the one in the EnumeratorWrapper class instance. Hence why the state of m_Enumerator wasn't getting updated. Hmm, ok. Well, why is it doing this? If you have a read of Eric Lippert's blog post about this issue, you'll notice he quotes a few sections of the C# spec. In particular, 7.5.4: ...if the field is readonly and the reference occurs outside an instance constructor of the class in which the field is declared, then the result is a value, namely the value of the field I in the object referenced by E. And my m_Enumerator field is readonly! Indeed, if I remove the readonly from the class variable then the problem goes away, and the code works as expected. The IL confirms this: .method public hidebysig newslot virtual final instance bool MoveNext() cil managed { .maxstack 1 .locals init ( [0] bool CS$1$0000) L_0000: nop L_0001: ldarg.0 L_0002: ldflda valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator EnumeratorWrapper::m_Enumerator L_0007: call instance bool [System]System.Collections.Generic.LinkedList`1/Enumerator::MoveNext() L_000c: stloc.0 L_000d: br.s L_000f L_000f: ldloc.0 L_0010: ret } Notice on line 0002, instead of the ldfld we had before, we've got a ldflda, which does this: Finds the address of a field in the object whose reference is currently on the evaluation stack. Instead of loading the value, we're loading the address of the m_Enumerator field. So now the call to MoveNext modifies the enumerator stored in the class rather than on the stack, and everything works as expected. Previously, I had thought enumerator structs were an odd but interesting feature of the BCL that I had used in the past to do linked list slices. However, effects like this only underline how dangerous mutable structs are, and I'm at a loss to explain why the enumerators were implemented as structs in the first place. (interestingly, the SortedList<TKey, TValue> enumerator is a struct but is private, which makes it even more odd - the only way it can be accessed is as a boxed IEnumerator!). I would love to hear people's theories as to why the enumerators are implemented in such a fashion. And bonus points if you can explain why LinkedList<int>.Enumerator.Reset is an explicit implementation but Dispose is implicit... Note to self: never ever ever code a mutable struct.

• WebCenter Content shared folders for clustering

  - by Kyle Hatlestad

  When configuring a WebCenter Content (WCC) cluster, one of the things which makes it unique from some other WebLogic Server applications is its requirement for a shared file system.  This is actually not any different then 10g and previous versions of UCM when it ran directly on a JVM.  And while it is simple enough to say it needs a shared file system, there are some crucial details in how those directories are configured. And if they aren't followed, you may result in some unwanted behavior. This blog post will go into the details on how exactly the file systems should be split and what options are required.

• What are the advantages and challenges of using HaXe over ActionScript 3?

  - by Arthur Wulf White

  I read this: http://webr3.org/blog/haxe/bitmapdata-vectors-bytearrays-and-optimization/ And this: http://stackoverflow.com/questions/5220045/what-are-the-pro-and-cons-of-using-haxe-over-actionscript-3 http://www.haxenme.org/developers/documentation/actionscript-developers/ I read there are only two books, is that right? http://haxe.org/doc/book I also see that using FlashDevelop you can make an Adobe Air project with HaXe and compile to exe. And begun to wonder from a game making perspective: I saw the example in the first link, are there any additional advantages in performance when using HaXe instead of AS3 for games development (for the web)?

• Programmers and tech email: Do you actually read all of them?

  - by AdityaGameProgrammer

  Email Alerts, Blog /Forum updates, discussion subscriptions general programming/technology update emails that we often subscribe to.Do you actually read them ? or go direct to the source when you find time. often we might the mail of programmers filled with loads of unread subscription mail from technology they previously were following or worked on or things they wish to follow .some or a majority of these mail just keep on piling up . i personally have few updates that i wish i read but constantly avoid and keep of for latter and finally delete them in effort keep the in box clean. few questions come to mind regarding this Do you keep such mail in separate accounts? Do you read all the mail you have subscribed to? Do you ever unsubscribe to any such email if you aren't reading them? How much do you really value these email. Lastly do you keep your in box clean ? wish to deal with this in a better way.

• Gnome Mplayer failed to open VDPAU backend libvdpau_nvidia.so

  - by Tim

  When I open an avi file under Gnome Mplayer, there is an error report: Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory I then followed this blog to solve this problem, which suggests two ways. The first way is to call mplayer in terminal: mplayer -vo xv video.wmv This works for me. But I would like to try the second way, which is to write options in one of the configure files of Gnome Mplayer. I choose to write into ~/.mplayer/config, where I wrote: -vo xv But it does not work. So I was wondering if I make any mistake? What to write into the configure file? Thanks and regards!

• Editor's Notebook: Of Slobber Pots and Flux Capacitors

  - by user462779

  Just wrapping up the contents of the November 2012 issue of Profit... I found this snippet of an interview I did with Team Oracle mechanics Clyde Greene and Chad Colberg when I was in Gary, IN this summer working on a photo shoot about Team Oracle for the current issue. We were standing around in a hangar as the Team prepared for the Chicago Air and Water Show, chatting about the engineering and design of the Oracle Challenger III aerobatic plane. Pick up a copy of Profit's November 2012 and read what Team Oracle pilot Sean D. Tucker has to say about the Oracle Challenger III and get a closer look at the plane. I'll drop a link into this blog entry as soon as the story is available. Your editor, greasy and stooped after a red eye flight, talks with Sean D. Tucker about stunt flying.

• Fix for EF4 Profiler Issue Coming in next Cumulative Update

  - by Ajarn Mark Caldwell

  Hey!  What do you know?  Microsoft Connect really works! I was very happy this morning to open my email and find a notice from Umachandar on the SQL Programmability Team that they have created a fix for the Odd Profiler Results with EF4 issue that I wrote about last June.  Not only did I blog about it, but I logged an item to Connect with repro steps and sample code.  And now, they have announced that they have a fix for this problem and that it will be included in the next Cumulative Update for SQL Server 2008 R2. For those of you not running 2008 R2, or who prefer to wait for full Service Packs rather than install the latest Cumulative Updates, I also wrote about a workaround for the issue, as long as you do not require the Multiple Active Result Sets feature to be enabled. It is easy with Microsoft to get the feeling that you’re just shouting in the wind, and it is nice to get validation once in a while that they really are listening.

• Example: Controlling randomizer using code contracts

  - by DigiMortal

  One cool addition to Visual Studio 2010 is support for code contracts. Code contracts make sure that all conditions under what method is supposed to run correctly are met. Those who are familiar with unit tests will find code contracts easy to use. In this posting I will show you simple example about static contract checking (example solution is included). To try out code contracts you need at least Visual Studio 2010 Standard Edition. Also you need code contracts package. You can download package from DevLabs Code Contracts page. NB! Speakers, you can use the example solution in your presentations as long as you mention me and this blog in your sessions. Solution has readme.txt file that gives you steps to go through when presenting solution in sessions. This blog posting is companion posting for Visual Studio solution referred below. As an example let’s look at the following class. public class Randomizer {     public static int GetRandomFromRange(int min, int max)     {         var rnd = new Random();         return rnd.Next(min, max);     }       public static int GetRandomFromRangeContracted(int min, int max)     {         Contract.Requires(min < max, "Min must be less than max");           var rnd = new Random();         return rnd.Next(min, max);     } } GetRandomFromRange() method returns results without any checking. GetRandomFromRangeContracted() uses one code contract that makes sure that minimum value is less than maximum value. Now let’s run the following code. class Program {     static void Main(string[] args)     {         var random1 = Randomizer.GetRandomFromRange(0, 9);         Console.WriteLine("Random 1: " + random1);           var random2 = Randomizer.GetRandomFromRange(1, 1);         Console.WriteLine("Random 2: " + random2);           var random3 = Randomizer.GetRandomFromRangeContracted(5, 5);         Console.WriteLine("Random 3: " + random3);           Console.WriteLine(" ");         Console.WriteLine("Press any key to exit ...");         Console.ReadKey();     } } As we have not turned on support for code contracts the code runs without any problems and we get no warnings by Visual Studio that something is wrong. Now let’s turn on static checking for code contracts. As you can see then code still compiles without any errors but Visual Studio warns you about possible problems with contracts. Click on image to see it at original size.  When we open Error list and run our application we get the following output to errors list. Note that these messages are not shown immediately. There is little delay between application starting and appearance of these messages. So wait couple of seconds before going out of your mind. Click on image to see it at original size.  If you look at these warnings you can see that warnings show you illegal calls and also contracts against what they are going. Third warning points to GetRandomFromRange() method and shows that there should be also problem that can be detected by contract. Download Code Contracts example VS2010 solution | 30KB

• How to create a good sitemap for dynamic website

  - by Saif Bechan

  I have a website with dynamic content and different kind of pages. I have some pages that rarely change, and I have pages like blogs that change often. The blog pages also have links for sorting, for example sorting on date, asc, desc. On some of the pages I also have links to different tabbed content, and links that are just anchor links. Now when I use a xml sitemap generator then all the links are thrown into the site, and so I don't think all the links are really relevant. The blogposts up until now are also taken into the sitemap. Is this really necessary? I think the links to the blogposts can be indexed just fine. Is the best way to make a sitemap just to manually assign the main menu links to the sitemap, or is indexing everything really recommended?

• We're Back: I'm Here

  - by [email protected]

  After a busy Fall and Winter post-Oracle OpenWorld 2009 Oracle's Application Strategy Blog is back. More on what we've been up to shortly. Me, I'm blogging here for the first time. After nearly 6 years at Oracle working on the Oracle Fusion Middleware business I've recently joined the Oracle Applications team. For me, what's old is new again. Prior to working on applications infrastructure at Oracle...and at BEA Systems before that...I worked at PeopleSoft in a number of roles spanning Enterprise Performance Management, Supply Chain, Public Sector and Financial Services and more. Some of the acronyms are the same, there are (of course) some new ones too. But what I'm really excited about is the intersection of Enterprise Applications and Applications Infrastructure that's happening right now. "Aligning IT with Business Strategy" has been the buzzphrase for longer than we can all remember---but what I've seen over the past 5 months makes me start to believe that it's finally starting to happen.

• A tale of two dev accounts

  - by TechTwaddle

  Note: I am currently in the process of relocating my blog from http://www.geekswithblogs.net/techtwaddle to my new address at http://www.techtwaddle.net I suggest you point your feed readers to the new address as I slowly transition to my new shared-hosted, ad-free wordpress blog :)   You probably remember my rant from a while back about my windows mobile developer account having problems with the new AppHub, well, there have been few developments and I thought I should share it with you. First up, the issue isn’t fixed yet. I still cannot login to AppHub using my windows mobile 6.x developer account and can’t view details of my Minesweeper app. Who knows how many copies its sold. I had numerous exchanges with Microsoft’s support team on the AppHub forums and via email as well (support ticket), but somehow we never managed to get to the root of it. In fact, the support team itself grew so tired of the problem that they suggested I create a new dev account. I grew impatient, and it was really frustrating to have an app ready for submission but not being able to do anything with it. Eventually, the frustration had to show somewhere, and it was on this forum thread Prabhu Kumar in reply to Nick Nick, I feel for you and totally understand the frustration. Since day one I have been getting the XBOX profile linking error, We encountered an issue connecting your App Hub account with your Xbox Live Profile. Please visit Xbox.com and update your contact information. After you have updated your contact information, please return to the App Hub (https://users.create.msdn.com/Register) to continue. I have an app published on the Windows Mobile 6.x marketplace since Aug, now I can't view the details of this app. I completed work on my WP7 application 1.5 months ago and the first version is ready for submission to marketplace, only if I can login. You can imagine how frustrating all this can be, the issue has taken far too long to be fixed, this has drained all my motivation. I have exchanged numerous mails with Microsoft support team on this issue, and from the looks of it they really are trying their best, unfortunately, their best is not good enough for some of us. During the first week of December I was told that there would be an update happening to AppHub around mid of December. I was hoping that the issue would be fixed but it wasn't. After the update the only change I notice is that the xbox.com link on the error page now takes me to the correct link. Previously, this link used to take me to the 404 page you mentioned above. Out of desperation, I am now considering creating another developer account on AppHub with a new live id, even this I am not 100% sure will work. I asked the support team when the next update to AppHub was planned and got this reply, "We do not have  release date to announce for the next App Hub update at this time. In regards to the login issue you are experiencing at this point the only solution would be to create a new account with a different live ID but make sure to go to xbox.com before hand to get all the information in order on that side." I know it's an extra $99, and not that I can't afford it but it doesn't feel right and I shouldn't have to be doing it in the first place. I have lost all hope of this issue being resolved. I went ahead and created a new dev account, the id verification was in progress when Shaun Taulbee of Microsoft, who has been really helpful in the forums, replied saying, If you find it necessary to pay again to create a new account due to a Microsoft problem, send in a support request asking for a refund and we'll review it (and likely approve it given the circumstances). The thought of refund made me happy, but I had my doubts. So once my second account was verified by Geotrust I applied for a refund through the developer dashboard, by creating a support ticket. Couple of days later I got an email from Microsoft saying that the refund had been approved! yay! Few days and the refund showed up on my bill, Well, thank you Microsoft, it means a lot. I am glad it’s over now. The new account works flawlessly. I would still like to get my first account working again and look at my app numbers for Win Mo 6.x, and probably transfer the credits to the new account somehow, but I’ll save it for another day. If you’ve had similar problems with the AppHub, and had to create a new account to submit your app, I suggest you contact the support team and get your dollars refunded!

• adding noindex on pagination

  - by Damodar Bashyal

  I find few conflicts on people's reactions about adding noindex on paginations. What does pro webmasters has to say about this? I am planning to add noindex meta for all paginations with a hope to increase website value, so I would like some pro's feedback on this. e.g. here: http://w3tut.org/blog 3 posts' first few paragraphs are displayed and meta is taken from first post from that page, which will cause duplicate meta issue. Also, 3 posts in a page could be unrelated to each other as well. Is it a good idea to add noindex for these pages, so full article posts get more value?
