• UPDATE FOR BI PUBLISHER ENTERPRISE 10.1.3.4.2 NOVEMBER 2011

  - by Tim Dexter

  It's Friday, that means its patch release time. Why do we do this to ourselves, 'we'll release on Friday!' It might 11.59 on Friday but by golly we'll have released on Friday. I can remember a release of BIP years ago that for some reason we went for 12/31 as a release date ... were we mad? I seem to remember we made it but talk about ridiculous pressure! The latest 10g rollup is out in the wild and available from Oracle support. A bug fixing rollup but worth getting to and know that support will want you to get to it and re-test before going forward on an SR. One simple but very useful fix or enhancement:[Cause of the bug] @ ================== @ Customer reports that despite the clock being shown, end users are clicking @ on the View button repeatedly as the initial generation is taking some time.   @ If the button were to be grayed out then  this would prevent the users @ requesting the report more than  once.  Repeated requests are causing a @ system overload and as this is their Production  instance this is extremely @ important to the customer. @ . @ [The Fix] @ ========= @ Added the logic to disable the button after the user clicks on the "view" @ button and re-enable it when the report is loaded. I told a group of customers once that they have a headache and we have a non-steroidal anti-inflammatory drug, alright, I actually said 'aspirin'. This little gem of a fix helps relieve another little headache that our aspirin was causing. The patch number for all this BIP pain killing is 13399232, enjoy!

• Antenna Aligner Part 8: It's Alive!!!

  - by Chris George

  Finally the day has come, Antenna Aligner v1.0.1 has been uploaded to the AppStore and . "Waiting for review" .. . fast forward 7 days and much checking of emails later WOO HOO! Now what? So I set my facebook page to go live  https://www.facebook.com/AntennaAligner, and started by sending messages to my mates that have iphones! Amazingly a few of them bought it! Similarly some of my colleagues were also kind enough to support me and downloaded it too! Unfortunately the only way I knew they had bought is was from them telling me, as the iTunes connect data is only updated daily at about midday GMT. This is a shame, surely they could provide more granular updates throughout the day? Although I suppose once an app has been out in the wild for a while, daily updates are enough. It would, however, be nice to get a ping when you make your first sale! I would have expected more feedback on my facebook page as well, maybe I'm just expecting too much, or perhaps I've configured the page wrong. The new facebook timeline layout is just confusing, and I'm not sure it's all public, I'll check that! So please take a look and see what you think! I would love to get some more feedback/reviews/suggestions... Oh and watch out for the Android version coming soon!

• Execution plan warnings–All that glitters is not gold

  - by Dave Ballantyne

  In a previous post, I showed you the new execution plan warnings related to implicit and explicit warnings.  Pretty much as soon as i hit ’post’,  I noticed something rather odd happening. This statement : select top(10) SalesOrderHeader.SalesOrderID, SalesOrderNumberfrom Sales.SalesOrderHeaderjoin Sales.SalesOrderDetail on SalesOrderHeader.SalesOrderID = SalesOrderDetail.SalesOrderID   Throws the “Type conversion may affect cardinality estimation” warning.     Ive done no such conversion in my statement why would that be ?  Well, SalesOrderNumber is a computed column , “(isnull(N'SO'+CONVERT([nvarchar](23),[SalesOrderID],0),N'*** ERROR ***'))”,  so thats where the conversion is.   Wait!!! Am i saying that every type conversion will throw the warning ?  Thankfully, no.  It only appears for columns that are used in predicates ,even if the predicate / join condition is fine ,  and the column is indexed ( and/or , presumably has statistics).    Hopefully , this wont lead to to many wild goose chases, but is definitely something to bear in mind.  If you want to see this fixed then upvote my connect item here.

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• How to have Windows 7 remember a password for a Domain

  - by Kelly Jones

  About eighteen months ago, I wrote a post covering how to clear saved passwords in Windows XP.  This week at work I was reminded how useful it is to not only deleted saved passwords, but to also setup wildcard credentials using this same interface. The scenario that I run into as consultant working at a client site, is that my laptop is not a member of the Windows Domain that my client uses to secure their network. So, when I need to access file shares, shared printers, or even the clients internal websites, I’m prompted for a name and password.  By creating a wildcard entry on my laptop (for the user account that the client issued to me), I avoid this prompt and can seamlessly access these resources.  (This also works when you’ve configured Outlook to access Exchange via RPC over HTTP.) How to create a credential wild card entry in Windows 7: Go to your Start Menu --> Type "user" into the Search box Click on the “Manage your credentials” in the column on the left Click on the “Add a Windows credential” link Enter the Domain (in my case my client’s domain), something like this: *.contoso.com Enter the username and password That’s it.  You should now be able to access resources in that Domain without being prompted for your name and password.  Please note: if you are required to change your password periodically for that domain, you’ll need to update your saved password as well.

• Architecture of a "website generator" web application

  - by Resorath

  What is the most maintainable and efficient way to architect a web application who's purpose is to host and generate websites which can be customized to a certain degree? There are a lot of these style of applications in the wild that generate all kinds of sites, from sites that host World of Warcraft guilds like guildlaunch to other sites like my wedding for wedding site hosting. My question is, what is the basic architecture that these sites operate on? I imagine there are two ways of thinking about this. A central set of code that all sites on the host run against, and it acts differently based on which site was visited. In this manner, when the base code is updated all sites are updated simultaneously. Or, the code for an individual site exists in a silo, and is simply replicated to a new directory each time a site is created. When an update needs to be applied, the code is pushed out to each site silo. In my case, I am working in PHP with the CodeIgniter framework, however the answer need not be limited to this case. Which method (if any) creates a more maintainable and efficient architecture to manage this style of web application?

• CodeStock 2012 Review: Eric Landes( @ericlandes ) - Automated Tests in to automated Builds! How to put the right type of automated tests in to the right automated builds.

  Automated Tests in to automated Builds! How to put the right type of automated tests in to the right automated builds.Speaker: Eric LandesTwitter: @ericlandesBlog: http://ericlandes.com/ This was one of the first sessions I attended during CodeStock 2012. Eric’s talk focused mostly on unit testing, and that the lack of proper unit testing can be compared to stealing from an employer. His point was that if you’re not doing proper unit testing then all of the time wasted on fixing issues that could have been detected with unit tests is like stealing money from employer. He makes the assumption that that time spent on fixing these issues could have been better spent developing new features that drive the business. To a point I can agree with Eric’s argument regarding unit testing and stealing from a company’s perspective. I can see how he relates resources being shifted from new development to bug fixes as stealing based on the fact that the resources used to fix bugs are directly taken from other projects. He also states that Boring/Redundant and Build/Test tasks should be automated because it reduces the changes of errors and frees up developer to do what they do best, DEVELOP! When he refers to testing, he breaks testing down in to four distinct types. Unit Test Acceptance Test (This also includes Integration Tests) Performance Test UI Test With this he also recommends that developers should not go buck wild striving for 100% code coverage because some test my not provide a great return on investment. In his experience he recommends that 70% test coverage was a very acceptable rate.

• protected abstract override Foo(); &ndash; er... what?

  - by Muljadi Budiman

  A couple of weeks back, a co-worker was pondering a situation he was facing.  He was looking at the following class hierarchy: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { } class FirstConcrete : SecondaryBase { } class SecondConcrete : SecondaryBase { } Basically, the first 2 classes are abstract classes, but the OriginalBase class has Test implemented as a virtual method.  What he needed was to force concrete class implementations to provide a proper body for the Test method, but he can’t do mark the method as abstract since it is already implemented in the OriginalBase class. One way to solve this is to hide the original implementation and then force further derived classes to properly implemented another method that will replace it.  The code will look like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected sealed override void Test() { Test2(); } protected abstract void Test2(); } class FirstConcrete : SecondaryBase { // Have to override Test2 here } class SecondConcrete : SecondaryBase { // Have to override Test2 here } With the above code, SecondaryBase class will seal the Test method so it can no longer be overridden.  Then it also made an abstract method Test2 available, which will force the concrete classes to override and provide the proper implementation.  Calling Test will properly call the proper Test2 implementation in each respective concrete classes. I was wondering if there’s a way to tell the compiler to treat the Test method in SecondaryBase as abstract, and apparently you can, by combining the abstract and override keywords.  The code looks like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected abstract override void Test(); } class FirstConcrete : SecondaryBase { // Have to override Test here } class SecondConcrete : SecondaryBase { // Have to override Test here } The method signature makes it look a bit funky, because most people will treat the override keyword to mean you then need to provide the implementation as well, but the effect is exactly as we desired.  The concepts are still valid: you’re overriding the Test method from its original implementation in the OriginalBase class, but you don’t want to implement it, rather you want to classes that derive from SecondaryBase to provide the proper implementation, so you also make it as an abstract method. I don’t think I’ve ever seen this before in the wild, so it was pretty neat to find that the compiler does support this case.

• EE vs Computer Science: Effect on Developers' Approaches, Styles?

  - by DarenW

  Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

• iPhone core data problem : referenceData64 only defined for abstract class

  - by occe

  I have an application that downloads/parses a big XML file and store the information using core data (approx. 4000 objects (entities)). The XML is loaded/parsed in a different thread, which has its own NSManagedObjectContext. When trying to save the entities to the persistent store, I sometimes get the following error (about 20%) 2010-03-03 23:41:42.802 xxx[7487:4203] Exception in XML saving 2010-03-03 23:41:42.802 xxx[7487:4203] Description: * -_referenceData64 only defined for abstract class.

Define -[NSTemporaryObjectID_default _referenceData64]! I have a simple integer to keep track of the entities the application creates compared to the insertedObjects property in the NSManagedObjectContext before saving, and when I get the error, these numbers do not match, insertedObjects in the NSManagedObjectContext is missing about 10 entities. I do not know how I should continue to investigate this problem, anyone has any idea how to fix this? Thanks /oscar

• ScoreNinja causes java.lang.RuntimeException: Can't create handler inside thread that has not called

  - by sirconnorstack

  I'm trying to add ScoreNinja, the global high score system, to my Android game, and it works fine when I load it on my phone, but when I release it into the wild, I got crash reports saying: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() Here is part of the call stack: android.os.Handler.<init>(Handler.java:121) android.app.Dialog.<init>(Dialog.java:99) android.app.AlertDialog.<init>(AlertDialog.java:65) android.app.AlertDialog.<init>(AlertDialog.java:61) android.app.AlertDialog$Builder.create(AlertDialog.java:797) android.app.AlertDialog$Builder.show(AlertDialog.java:812) com.scoreninja.adapter.ScoreNinjaAdapter.show(ScoreNinjaAdapter.java:136) com.scoreninja.adapter.ScoreNinjaAdapter.show(ScoreNinjaAdapter.java:99) I thought the main thread had prepare() called automatically, and if not, why would it work fine for me but not anyone else?

• Windows batch file to delete .svn files and folders

  - by Marco Demaio

  Hi,in order to delete all ".svn" files/folders/subfolders in "myfolder" I use this simple line in a batch file: FOR /R myfolder %%X IN (.svn) DO (RD /S /Q "%%X") This works, but if there are no ".svn" files/folders the batch file shows a warning saying: "The system cannot find the file specified." This warning is very noisy so I was wondering how to make it understand that if it doesn't find any ".svn" files/folders he must skip the RD command. Usually using wild cards would suffice, but in this case I don't know how to use them, because I don't want to delete files/folders with .svn extension, but I want to delete the files/folders named exactly ".svn", so if I do this: FOR /R myfolder %%X IN (*.svn) DO (RD /S /Q "%%X") it would NOT delete files/folders named extaclty ".svn" anymore. I tried also this: FOR /R myfolder %%X IN (.sv*) DO (RD /S /Q "%%X") but it doesn't work either, he deletes nothing. Thanks for any help!

• Are the svn ruby bindings provided as a gem?

  - by user30997

  I see a couple dozen gems that relate to svn, but what little documentation I can find on any of them shows that they are command-line wrappers and misc helpers. (svn-command, svn-hooks, etc.) I've seen code in the wild that does things like: require 'svn/core' and SVN.Repos.add(...), but the author of that module pulled his svn ruby tools via apt-get. This would not be an option for me, as I'm developing a windows/osx tool. Which gem am I after? From there, I'm happy to dig through code in lieu of documents, but with a call to gem query --name-matches svn --remote returning about 30 hits, I need to narrow it down a bit first.

• ASPX has image from portal.mxlogic.com

  - by codie

  I have a aspx page I'm trying to (remotely) debug. It should add an image and set the src. The value seems correct if i msgbox the value that should be used for the "ImageUrl" But viewing the page there is no image and the src is: http://portal.mxlogic.com/images/transparent.gif This is a mcaffee page so is this some security thing...that is just a wild\crazy guess. Maybe i'm missing something very obvious...I did not write the code and I'm not really a aspx developer. Any ideas?? llf as requested some code... TableCell tc = new TableCell(); {code to create imgurl ... very specific to this situation} MessageBox(imgurl); //The imgurl value here is correct if (imgurl != null) { image.ImageUrl = imgurl; } else { MessageBox("image url is null"); } tc.Controls.Add(image); tr.Cells.Add(tc); Table1.Rows.Add(tr)

• How to prevent code/option injection in a bash script

  - by asmaier

  I have written a small bash script called "isinFile.sh" for checking if the first term given to the script can be found in the file "file.txt": #!/bin/bash FILE="file.txt" if [ `grep -w "$1" $FILE` ]; then echo "true" else echo "false" fi However, running the script like > ./isinFile.sh -x breaks the script, since -x is interpreted by grep as an option. So I improved my script #!/bin/bash FILE="file.txt" if [ `grep -w -- "$1" $FILE` ]; then echo "true" else echo "false" fi using -- as an argument to grep. Now running > ./isinFile.sh -x false works. But is using -- the correct and only way to prevent code/option injection in bash scripts? I have not seen it in the wild, only found it mentioned in ABASH: Finding Bugs in Bash Scripts.

• Is this design possible with ExtJS?

  - by gargantaun

  I've been asked to do the front end for a web app, and to use ExtJS specifically. I've been working through a couple of tutorials, but I've not seen much variation on the default ExtJS look and feel except for some subtle changes to the colors and what not. The design I've been handed seems to be a radical departure from the standard ExtJs look and feel. So before I head down a dead end or start chasing wild geese, I wondered wether any ExtJS experts out there could point out any potential pit falls in the design, or is everything do-able? The design is here... cheers -t

• Video Synthesis - Making waves, patterns, gradients...

  - by Nathan

  I'm writing a program to generate some wild visuals. So far I can paint each pixel with a random blue value: for (y = 0; y < YMAX; y++) { for (x = 0; x < XMAX; x++) { b = rand() % 255; setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise, but I'm not sure where to start (Google isn't helping me much today), so it would be great if you could share anything you know on the subject or some links to related resources.

• multiplayer / visitors interactions with Ruby on Rails?

  - by Jordi

  I want to have interactions between visitors on my site. Imagine a chat room. It basically involves getting the data from everyone and sending it to everyone, this can be done by ajax and what not but I wonder if there is something already there in the wild that would do the heavy lifting for me. I have to say that I got very lost once I start programming Ajax, dont even know how to make tests for it... I have found the Q42multiplayer library that looks like what I want but they use C# as backend. There is something similar or any other multiplayer thingy I can get some idea or rip some code from (the whole thing will be opensource) for Ruby on Rails?

• UrlEncoding-Safe Delimiter

  - by Aren B

  So the site I'm working on has a filter system that operates by passing a key and value system through a querystring. The whole site is going through a re-factor soon and I'm maintaining the existing site so before we discuss the RIGHT way to implement this, I just need ideas for changing my delimiter. The current format is like this: cf=<key>:<value> The problem is, I've recently run into an issue because some of our new values for this filter contain : in them. I.e: cf=MO_AspectRatio:16:10 The value is being UrlEncoded, but the browsers are de-coding %3a into : on the fly because the : doesn't inherently break the urls. I need some suggestions for url-safe delimiters that aren't :,-,_,&,? that makes sense. I'm not looking for a solution like () or something wild.

• Website looks weird in internet explorer 7, but fine in IE 6 and 8

  - by user156814

  I used many different browsers while I was coding for a new site (Firefox, Chrome, IE8, Opera, Safari, Mobile devices, etc...). It looked the same across all browsers. I recently uploaded the site onto the server and got to look at it from work, using Internet Explorer 7 and It looks horrible. Elements are floating wild all over the place, but I cant figure out why. The weird thing is I just looked at it from IE6, and it looks fine, with the exception of unsupported transparencies in PNG's. If anybody has IE7, you can view the site here. Thanks

• Reading iTunesMovies file in iPhone?

  - by raziiq

  Hi there. In iPhone, the iPod app saves the media files (audio, video) with strange names and in weird folders (F00,F01 etc). There is a file named iTunesMovies in iPhone, which contains all the information about the metadata of those video files and how they are to be displayed in iPod app. I copied that to my Mac also, and when i tried to open that file in textEdit, it showed some alien characters which made me believe that it is encrypted may be(Thats just a wild guess). I want to read/change the contents of that iTunesMovies file. Can i do that? Is there any Framework which deals with that iTunesMovies file? Thanks in advance

• Collaborative text editing in a web application

  - by UmYeah

  I have a group of writers around the world all trying to work on one story. I want them to be able to work with each other like they would on google documents, but from within our application. Specifically, being able to see who else is working on the document and what they are changing in real time. Something like an embedded etherpad. Are there any good solutions out in the wild? Im sure building something like this would be a significant project.

• Best way to update badgeValue of UITabBarController from a UIView

  - by Rudiger

  Hi everyone, I have a tabBarController set up in the AppDelegate and have a few UIViewControllers with Nav Controllers. In one of the TabBar items, after I have pushed a few UIViews I want to update the badgeValue item of a different TabBar item. Whats the best way to do this? The only way I can really think is a NSNotification and a singleton storage for the value, but it seems a lot of work for something simple, that and I have no idea about NSNotifications. I had a wild guess at something like super.tabBarController.otherView.badgeValue = @"1" (as I set which tab is selected in a similar way) but I'm not surprised this doesn't work. Thanks
