NSMutableArray memory management

- by chicken

NSMutableArray *a1 = [[NSMutableArray alloc] init]; NSMutableArray *a2 = [NSMutableArray array]; TempObj *obj = [[TempObj alloc] init]; //assume this line is repeated for each obj [a1 addObject:obj]; [a1 addObject:obj2]; [a1 addObject:obj3]; [a1 addObject:obj4]; [obj release]; [obj2 release]; [obj3 release]; [obj4 release]; [a1 release]; Ok so a2 is an autorelease obj so i dont have to call release on it? Also how do you know when you get an autorelease object? And for a1, i dont have to loop through the array and release each object first? What if i called [a1 removeAllObjects]; does that call [[a1 objectAtIndex:#] release]; Am i supposed to release those objects after ive added them to the array?

Upgrading 13.04 to 13.10, could not calculate the upgrade

- by topless

I am running sudo update-manager -d and start the upgrade process. I select upgrade option and when then manager enters Setting new software channels it throws an error. Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. I have disabled all unofficial and third party packages, I am not running a pre-release version since I am at 13.04 and I am trying to update to beta 2 which is not a pre-release. Before I fill a bug report, since its happening to both of my systems I would like to figure out if anyone else had same issues.

What Apache/PHP configurations do you know and how good are they?

- by FractalizeR

Hello. I wanted to ask you about PHP/Apache configuration methods you know, their pros and cons. I will start myself: ---------------- PHP as Apache module---------------- Pros: good speed since you don't need to start exe every time especially in mpm-worker mode. You can also use various PHP accelerators in this mode like APC or eAccelerator. Cons: if you are running apache in mpm-worker mode, you may face stability issues because every glitch in any php script will lead to unstability to the whole thread pool of that apache process. Also in this mode all scripts are executed on behalf of apache user. This is bad for security. mpm-worker configuration requires PHP compiled in thread-safe mode. At least CentOS and RedHat default repositories doesn't have thread-safe PHP version so on these OSes you need to compile at least PHP yourself (there is a way to activate worker mpm on Apache). The use of thread-safe PHP binaries is considered experimental and unstable. Plus, many PHP extensions does not support thread-safe mode or were not well-tested in thread-safe mode. ---------------- PHP as CGI ---------------- This seems to be the slowest default configuration which seems to be a "con" itself ;) ---------------- PHP as CGI via mod_suphp ---------------- Pros: suphp allows you to execute php scipts on behalf of the script file owner. This way you can securely separate different sites on the same machine. Also, suphp allows to use different php.ini files per virtual host. Cons: PHP in CGI mode means less performance. In this mode you can't use php accelerators like APC because each time new process is spawned to handle script rendering the cache of previous process useless. BTW, do you know the way to apply some accelerator in this config? I heard something about using shm for php bytecode cache. Also, you cannot configure PHP via .htaccess files in this mode. You will need to install PECL htscanner for this if you need to set various per-script options via .htaccess (php_value / php_flag directives) ---------------- PHP as CGI via suexec ---------------- This configuration looks the same as with suphp, but I heard, that it's slower and less safe. Almost same pros and cons apply. ---------------- PHP as FastCGI ---------------- Pros: FastCGI standard allows single php process to handle several scripts before php process is killed. This way you gain performance since no need to spin up new php process for each script. You can also use PHP accelerators in this configuration (see cons section for comment). Also, FCGI almost like suphp also allows php processes to be executed on behalf of some user. mod_fcgid seems to have the most complete fcgi support and flexibility for apache. Cons: The use of php accelerator in fastcgi mode will lead to high memory consumption because each PHP process will have his own bytecode cache (unless there is some accelerator that can use shared memory for bytecode cache. Is there such?). FastCGI is also a little bit complex to configure. You need to create various configuration files and make some configuration modifications. It seems, that fastcgi is the most stable, secure, fast and flexible PHP configuration, however, a bit difficult to be configured. But, may be, I missed something? Comments are welcome!

DotNetNuke 5.3.1 Released

I am happy to announce that the DotNetNuke 5.3.1 release is now available for download. This release was focused on fixing 3 significant issues with the 5.3.0 release which caused us to remove the release from CodePlex and our DotNetNuke Support Network. It is never easy to admit that significant issues slipped through testing and made it into a release package forcing you to take drastic actions. The only thing we can do is to re-evaluate our processes and continue to find areas for improvement...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

Guidance: How to layout you files for an Ideal Solution

- by Martin Hinshelwood

Creating a solution and having it maintainable over time is an art and not a science. I like being pedantic and having a place for everything, no matter how small. For setting up the Areas to run Multiple projects under one solution see my post on When should I use Areas in TFS instead of Team Projects and for an explanation of branching see Guidance: A Branching strategy for Scrum Teams. Update 17th May 2010 – We are currently trialling running a single Sprint branch to improve our history. Whenever I setup a new Team Project I implement the basic version control structure. I put “readme.txt” files in the folder structure explaining the different levels, and a solution file called “[Client].[Product].sln” located at “$/[Client]/[Product]/DEV/Main” within version control. Developers should add any projects you need to create to that solution in the format “[Client].[Product].[ProductArea].[Assembly]” and they will automatically be picked up and built automatically when you setup Automated Builds using Team Foundation Build. All test projects need to be done using MSTest to get proper IDE and Team Foundation Build integration out-of-the-box and be named for the assembly that it is testing with a naming convention of “[Client].[Product].[ProductArea].[Assembly].Tests” Here is a description of the folder layout; this content should be replicated in readme files under version control in the relevant locations so that even developers new to the project can see how to do it. Figure: The Team Project level - at this level there should be a folder for each the products that you are building if you are using Areas correctly in TFS 2010. You should try very hard to avoided spaces as these things always end up in a URL eventually e.g. "Code Auditor" should be "CodeAuditor". Figure: Product Level - At this level there should be only 3 folders (DEV, RELESE and SAFE) all of which should be in capitals. These folders represent the three stages of your application production line. Each of them may contain multiple branches but this format leaves all of your branches at the same level. Figure: The DEV folder is where all of the Development branches reside. The DEV folder will contain the "Main" branch and all feature branches is they are being used. The DEV designation specifies that all code in every branch under this folder has not been released or made ready for release. And feature branches MUST merge (Forward Integrate) from Main and stabilise prior to merging (Reverse Integration) back down into Main and being decommissioned. Figure: In the Feature branching scenario only merges are allowed onto Main, no development can be done there. Once we have a mature product it is important that new features being developed in parallel are kept separate. This would most likely be used if we had more than one Scrum team working on a single product. Figure: when we are ready to do a release of our software we will create a release branch that is then stabilised prior to deployment. This protects the serviceability of of our released code allowing developers to fix bugs and re-release an existing version. Figure: All bugs found on a release are fixed on the release. All bugs found in a release are fixed on the release and a new deployment is created. After the deployment is created the bug fixes are then merged (Reverse Integration) into the Main branch. We do this so that we separate out our development from our production ready code. Figure: SAFE or RTM is a read only record of what you actually released. Labels are not immutable so are useless in this circumstance. When we have completed stabilisation of the release branch and we are ready to deploy to production we create a read-only copy of the code for reference. In some cases this could be a regulatory concern, but in most cases it protects the company building the product from legal entanglements based on what you did or did not release. Figure: This allows us to reference any particular version of our application that was ever shipped. In addition I am an advocate of having a single solution with all the Project folders directly under the “Trunk”/”Main” folder and using the full name for the project folders.. Figure: The ideal solution If you must have multiple solutions, because you need to use more than one version of Visual Studio, name the solutions “[Client].[Product][VSVersion].sln” and have it reside in the same folder as the other solution. This makes it easier for Automated build and improves the discoverability of your code and its dependencies. Send me your feedback!

OpenSSL Versions in Solaris

- by darrenm

Those of you have have installed Solaris 11 or have read some of the blogs by my colleagues will have noticed Solaris 11 includes OpenSSL 1.0.0, this is a different version to what we have in Solaris 10. I hope the following explains why that is and how it fits with the expectations on binary compatibility between Solaris releases. Solaris 10 was the first release where we included OpenSSL libraries and headers (part of it was actually statically linked into the SSH client/server in Solaris 9). At time we were building and releasing Solaris 10 the current train of OpenSSL was 0.9.7. The OpenSSL libraries at that time were known to not always be completely API and ABI (binary) compatible between releases (some times even in the lettered patch releases) though mostly if you stuck with the documented high level APIs you would be fine. For this reason OpenSSL was classified as a 'Volatile' interface and in Solaris 10 Volatile interfaces were not part of the default library search path which is why the OpenSSL libraries live in /usr/sfw/lib on Solaris 10. Okay, but what does Volatile mean ? Quoting from the attributes(5) man page description of Volatile (which was called External in older taxonomy): Volatile interfaces can change at any time and for any reason. The Volatile interface stability level allows Sun pro- ducts to quickly track a fluid, rapidly evolving specif- ication. In many cases, this is preferred to providing additional stability to the interface, as it may better meet the expectations of the consumer. The most common application of this taxonomy level is to interfaces that are controlled by a body other than Sun, but unlike specifications controlled by standards bodies or Free or Open Source Software (FOSS) communities which value interface compatibility, it can not be asserted that an incompatible change to the interface specifica- tion would be exceedingly rare. It may also be applied to FOSS controlled software where it is deemed more important to track the community with minimal latency than to provide stability to our customers. It also common to apply the Volatile classification level to interfaces in the process of being defined by trusted or widely accepted organization. These are generically referred to as draft standards. An "IETF Internet draft" is a well understood example of a specification under development. Volatile can also be applied to experimental interfaces. No assertion is made regarding either source or binary compatibility of Volatile interfaces between any two releases, including patches. Applications containing these interfaces might fail to function properly in any future release. Note that last paragraph! OpenSSL is only one example of the many interfaces in Solaris that are classified as Volatile. At the other end of the scale we have Committed (Stable in Solaris 10 terminology) interfaces, these include things like the POSIX APIs or Solaris specific APIs that we have no intention of changing in an incompatible way. There are also Private interfaces and things we declare as Not-an-Interface (eg command output not intended for scripting against only to be read by humans). Even if we had declared OpenSSL as a Committed/Stable interface in Solaris 10 there are allowed exceptions, again quoting from attributes(5): 4. An interface specification which isn't controlled by Sun has been changed incompatibly and the vast majority of interface consumers expect the newer interface. 5. Not making the incompatible change would be incomprehensible to our customers. In our opinion and that of our large and small customers keeping up with the OpenSSL community is important, and certainly both of the above cases apply. Our policy for dealing with OpenSSL on Solaris 10 was to stay at 0.9.7 and add fixes for security vulnerabilities (the version string includes the CVE numbers of fixed vulnerabilities relevant to that release train). The last release of OpenSSL 0.9.7 delivered by the upstream community was more than 4 years ago in Feb 2007. Now lets roll forward to just before the release of Solaris 11 Express in 2010. By that point in time the current OpenSSL release was 0.9.8 with the 1.0.0 release known to be coming soon. Two significant changes to OpenSSL were made between Solaris 10 and Solaris 11 Express. First in Solaris 11 Express (and Solaris 11) we removed the requirement that Volatile libraries be placed in /usr/sfw/lib, that means OpenSSL is now in /usr/lib, secondly we upgraded it to the then current version stream of OpenSSL (0.9.8) as was expected by our customers. In between Solaris 11 Express in 2010 and the release of Solaris 11 in 2011 the OpenSSL community released version 1.0.0. This was a huge milestone for a long standing and highly respected open source project. It would have been highly negligent of Solaris not to include OpenSSL 1.0.0e in the Solaris 11 release. It is the latest best supported and best performing version. In fact Solaris 11 isn't 'just' OpenSSL 1.0.0 but we have added our SPARC T4 engine and the AES-NI engine to support the on chip crypto acceleration. This gives us 4.3x better AES performance than OpenSSL 0.9.8 running on AIX on an IBM POWER7. We are now working with the OpenSSL community to determine how best to integrate the SPARC T4 changes into the mainline OpenSSL. The OpenSSL 'pkcs11' engine we delivered in Solaris 10 to support the CA-6000 card and the SPARC T1/T2/T3 hardware is still included in Solaris 11. When OpenSSL 1.0.1 and 1.1.0 come out we will asses what is best for Solaris customers. It might be upgrade or it might be parallel delivery of more than one version stream. At this time Solaris 11 still classifies OpenSSL as a Volatile interface, it is our hope that we will be able at some point in a future release to give it a higher interface stability level. Happy crypting! and thank-you OpenSSL community for all the work you have done that helps Solaris.

How does having the Debugger change the game execution on an XBOX 360?

- by Sebastian Gray

So I thought my issue was relating to the difference between a Debug and a Release build as per this question: What's the difference between a "Release" Xbox 360 build and a "Debug" one? but I've since found that if I go ahead and build a Creators Club version of the game using a Debug build and deploy to the XBOX, I get the same experience I had with the Release version of my game. However if I run the game from Visual Studio using F5 and having set the XBOX as the default platform, then the game runs as expected. If I change from Debug to Release and run with CTRL+F5 then the game also works as expected. How would running the game with the debugger attached change the results I am getting in game? Is there any way that I can use the same approach or change the default compilation of the game so that I can use this approach to release my game?

How can I keep straight alpha during rendering particles?

- by April

Rencently,I was trying to save textures of 3D particles so that I can reuse the in 2D rendering.Now I had some problem with alpha channel.Some artist told me I that my textures should have unpremultiplied alpha channel.When I try to get the rgb value back,I got strange result.Some area went lighter and even totally white.I mainly focus on additive and blend mode,that is: ADDITIVE: srcAlpha VS 1 BLEND: srcAlpha VS 1-srcAlpha I tried a technique called premultiplied alpha.This technique just got you the right rgb value,its all you need on screen.As for alpha value,it worked well with BLEND mode,but not ADDITIVE mode.As you can see in parameters,BLEND mode always controlled its value within 1.While ADDITIVE mode cannot guarantee. I want proper alpha,but it just got too big or too small consider to rgb.Now what can I do?Any help will be great thankful. PS:If you don't understand what I am trying to do,there is a commercial software called "Particle Illusion".You can create various particles and then save the scene to texture,where you can choose to remove background of particles. Now,I changed the title.For some software like maya or AE,what I want is called [straight alpha].

Why we need apache Tomcat server to deploy any application. or what are the requirements to deploy any code or release?

- by Shank_SCM

I am asking very basic concept as I am new to build and release team. I am working with ant scripts to build and deploy the java code + working with TFS to deploy .net code. So my question is: What is apache tomcat and why we need it? Can't we deploy any piece of code or any application without apache tomcat? For windows, what framework we need to deploy(or same tomcat can be used for same)? Please make me understand the basic concept so that I can understand the deploy process or per-requisites of deploying process. what I know (to deploy) Just copy the tar file or zip file to any concerned dev environment and restart the server. Thats it. Please correct me if I am wrong.

Dot Net Nuke module works in "Edit" mode but not for "View": cache problem?

- by Godeke

I have a DNN task that simply runs some Javascript to compute a price based on a few input fields. This module works fine on our production site, but we had a company do a skin for us to improve the look of the site and the module fails under this new system. (DNN 05.06.00 (459) although it was 5.5 prior... I updated in a futile hope that it was a bug in the old revision.) What is incredibly odd about this is that the module works fine when I'm logged in to DNN and using the Edit mode as an administrator. In this case the small snippet of JavaScript loads fine and filling the fields results in a price. On the other hand it I click "View" (or more importantly, if I'm not logged in at all) the page loads a cached copy. Even odder, I have found the cache files in \Portals\2\Cache\Pages are generated and then only the cached data is being used. When the cached copy is loaded, the JavaScript doesn't appear (it is normally created via a Page.ClientScript.RegisterClientScriptBlock(). Additionally, the button which posts the data to the server doesn't execute any of the server side code (confirmed with a debugger) but instead just reloads the cached copy. If I manually delete the files in \Portals\2\Cache\Pages then everything works properly, but I have to do so after every page load: failing to do so simply loads the page as it was last generated repeatedly. Resetting the application (either via the UI or editing web.config) doesn't change this and clearing the cache from the Host Settings page doesn't actually clear these cached pages. I'm guessing that Edit mode bypasses the cache in some way, but I have gone as far as turning off all caching on the site (which is horrible for performance) and the cached version is still loaded. Has anyone seen anything like this? Shouldn't clearing the cache clear the files (I'm using the File provider for caching)? Shouldn't even a cached page go back to the server if the user posts back? EDIT: I should point out that permissions don't appear to be a problem on the cache directory... other pages cached output are deleted from this folder, just this page has this issue. EDIT 2: Clarifying some settings and conditions which I didn't provide. First, this module works fine in production under DNN 5.6.0. In our test environment with the consulting company's changes it fails (the changes are skin and page layout only in theory: the module source itself verifies as unchanged). All cache settings and the like have been verified the same between the two and we only resorted to setting the module cache to 0 and -1 (and disabling the test site's cache entirely) when we couldn't find another cause for the problem. I have watched the cache work correctly on many other pages in test: there is something about this page that is causing the problem. We have punted and are creating an installable skin based on the consultant's work as I suspect they have somehow corrupted the DNN install (database side I think).

"FOR UPDATE" v/s "LOCK IN SHARE MODE" : Allow concurrent threads to read updated "state" value of locked row

- by shadesco

I have the following scenario: User X logs in to the application from location lc1: call it Ulc1 User X (has been hacked, or some friend of his knows his login credential, or he just logs in from a different browser on his machine,etc.. u got the point) logs in at the same time from location lc2: call it Ulc2 I am using a main servlet which : - gets a connection from database pooling - sets autocommit to false - executes a command that goes through app layers: if all successful, set autocommit to true in a "finally" statement, and closes connection. Else if an exception happens, rollback(). In my database (mysql/innoDb) i have a "history" table, with row columns: id(primary key) |username | date | topic | locked The column "locked" has by default value "false" and it serves as a flag that marks if a specific row is locked or not. Each row is specific to a user (as u can see from the username column) So back to the scenario: --Ulc1 sends the command to update his history from the db for date "D" and topic "T". --Ulc2 sends the same command to update history from the db for the same date "D" and same topic "T" at the exact same time. I want to implement an mysql/innoDB locking system that will enable whichever thread arriving to do the following check: Is column "locked" for this row true or not? if true, return a message to the user that " he is already updating the same data from another location" if not true (ie not locked) : flag it as locked and update then reset locked to false once finished. Which of these two mysql locking techniques, will actually allow the 2nd arriving thread from reading the "updated" value of the locked column to decide wt action to take?Should i use "FOR UPDATE" or "LOCK IN SHARE MODE"? This scenario explains what i want to accomplish: - Ulc1 thread arrives first: column "locked" is false, set it to true and continue updating process - Ulc2 thread arrives while Ulc1's transaction is still in process, and even though the row is locked through innoDb functionalities, it doesn't have to wait but in fact reads the "new" value of column locked which is "true", and so doesn't in fact have to wait till Ulc1 transaction commits to read the value of the "locked" column(anyway by that time the value of this column will already have been reset to false). I am not very experienced with the 2 types of locking mechanisms, what i understand so far is that LOCK IN SHARE MODE allow other transaction to read the locked row while FOR UPDATE doesn't even allow reading. But does this read gets on the updated value? or the 2nd arriving thread has to wait the first thread to commit to then read the value? Any recommendations about which locking mechanism to use for this scenario is appreciated. Also if there's a better way to "check" if the row has been locked (other than using a true/false column flag) please let me know about it. thank you SOLUTION (Jdbc pseudocode example based on @Darhazer's answer) Table : [ id(primary key) |username | date | topic | locked ] connection.setautocommit(false); //transaction-1 PreparedStatement ps1 = "Select locked from tableName for update where id="key" and locked=false); ps1.executeQuery(); //transaction 2 PreparedStatement ps2 = "Update tableName set locked=true where id="key"; ps2.executeUpdate(); connection.setautocommit(true);// here we allow other transactions threads to see the new value connection.setautocommit(false); //transaction 3 PreparedStatement ps3 = "Update tableName set aField="Sthg" where id="key" And date="D" and topic="T"; ps3.executeUpdate(); // reset locked to false PreparedStatement ps4 = "Update tableName set locked=false where id="key"; ps4.executeUpdate(); //commit connection.setautocommit(true);

The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the app

- by Nick

I am having a problem submitting my new app to the appstore. ItunesConnect gives me the error: The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application. I haven't changed anything, I can compile to a ad-hoc certificate and that works fine. I uploaded another app yesterday and that worked fine too. All the targets and project info is set to compile to the base SDK iPhone OS 3.0. I even upgraded to the latest SDK but same result. Any ideas?

itunes connect rejection: "The binary you uploaded was invalid. A pre-release beta version of the SD

- by Adam

I'm having trouble submitting apps on Apple's app store. I was using a beta version of xcode- 3.2.3/iphone sdk 4.0- and I assumed that if I set the base sdk and deployment target to an acceptable version it would work, but it didn't. I deleted the beta version of xcode/sdk using "sudo /Developer/Library/uninstall-devtools --mode=all" and did a fresh install of the old release version- xcode 3.2.2/iphone sdk 3.2- but I still have the same problem. Has anyone run into this before? Is there something left over from the beta version that could still be hanging around causing problems?

Iphone NSXMLParser NSCFString memory leak

- by atticusalien

I am building an app that parses an rss feed. In the app there are two different types of feeds with different names for the elements in the feed, so I have created an NSXMLParser NSObject that takes the name of the elements of each feed before parsing. Here is my code: NewsFeedParser.h #import @interface NewsFeedParser : NSObject { NSInteger NewsSelectedCategory; NSXMLParser *NSXMLNewsParser; NSMutableArray *newsCategories; NSMutableDictionary *NewsItem; NSMutableString *NewsCurrentElement, *NewsCurrentElement1, *NewsCurrentElement2, *NewsCurrentElement3; NSString *NewsItemType, *NewsElement1, *NewsElement2, *NewsElement3; NSInteger NewsNumElements; } - (void) parseXMLFileAtURL:(NSString *)URL; @property(nonatomic, retain) NSString *NewsItemType; @property(nonatomic, retain) NSString *NewsElement1; @property(nonatomic, retain) NSString *NewsElement2; @property(nonatomic, retain) NSString *NewsElement3; @property(nonatomic, retain) NSMutableArray *newsCategories; @property(assign, nonatomic) NSInteger NewsNumElements; @end NewsFeedParser.m #import "NewsFeedParser.h" @implementation NewsFeedParser @synthesize NewsItemType; @synthesize NewsElement1; @synthesize NewsElement2; @synthesize NewsElement3; @synthesize newsCategories; @synthesize NewsNumElements; - (void)parserDidStartDocument:(NSXMLParser *)parser{ } - (void)parseXMLFileAtURL:(NSString *)URL { newsCategories = [[NSMutableArray alloc] init]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@"\n" withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; //you must then convert the path to a proper NSURL or it won't work NSURL *xmlURL = [NSURL URLWithString:URL]; // here, for some reason you have to use NSClassFromString when trying to alloc NSXMLParser, otherwise you will get an object not found error // this may be necessary only for the toolchain [[NSURLCache sharedURLCache] setMemoryCapacity:0]; [[NSURLCache sharedURLCache] setDiskCapacity:0]; NSXMLNewsParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; // Set self as the delegate of the parser so that it will receive the parser delegate methods callbacks.

Here is a screen shot of the Leaks instrument with the NSCFStrings leaking: http://img139.imageshack.us/img139/3997/leaks.png For the life of me I can't figure out where these leaks are coming from.

Code folding for LaTeX in Emacs

- by ShreevatsaR

Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections. Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode. [Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]

Event Capturing vs Event Bubbling

- by Rajat

I just wanted to get the general consensus on which is a better mode of event delegation in JS between bubbling and capturing. Now I understand that depending on a particular use-case, one might want to use capturing phase over bubbling or vice versa but I want to understand what delegation mode is preferred for most general cases and why (to me it seems bubbling mode). Or to put it in other words, is there a reason behind W3C addEventListener implementation to favor the bubbling mode. [capturing is initiated only when you specify the 3rd parameter and its true. However, you can forget that 3rd param and bubbling mode is kicked in] I looked up the JQuery's bind function to get an answer to my question and it seems it doesn't even support events in capture phase (it seems to me because of IE not support capturing mode). So looks like bubbling mode is the default choice but why?

How to reset ASP.NET MVC client validation mode?

- by Morten Christiansen

I'm having a bit of trouble with the client-side validation in the ASP.NET MVC 2 framework and hope someone can help me out. In several situations I find it useful to be able to reset the contents of a form or just a single input element and I need any validation errors to disappear. This in itself is not very hard, and the suggestion provided here works well enough: http://stackoverflow.com/questions/2798427/how-do-i-clear-mvc-client-side-validation-errors-when-a-cancel-button-is-clicked The problem is that, when triggered, client validation goes into an aggressive mode that performs validation on each key press and when an input loses focus. Is there a good way to reset this state as well?

How to launch the market intent in 'Give Feedback' mode on android.

- by Paul Maidment

Hi There, I have just written a game for the Android market and would like to remind my customers to leave feeback on the market for the application (especially the demo version.) Is there any way to launch the market intent in a mode that will take the user to the feedback / comments section of the page? I already use this approach for linking my demo to the paid app... Intent goToMarket = null; goToMarket = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=com.paulmaidment.games.flagsoftheworld")); startActivity(goToMarket); Is there a best practice that any Android devs out there might know of? Additionally, is there any way to track referalls from my demo app so that I can try to calculate some kind of a conversion rate? (i.e. how effective the demo app is at generating sales.) Thanks, Paul
