• iOS: Releasing Object Thats In Use (ARC)

  - by RileyE

  I have an object that I have created that subscribes to some NSNotificationCenter notifications, but it is being released, since I don't have a pointer to the instantiation. The instantiation has a delegate that will call a method back to another class I have, so I felt it unnecessary to also have a pointer to it, since the pointer doesn't serve any purpose. Basically, I have an instantiation of a class, DelegateListener (name is just for example purposes), which subscribes to some of the default NSNotificationCeneter's notifications. This instantiation isn't assigned to any pointer after the instantiation ends. The instantiation, however, has a property, delegate. I assign a value to that delegate during the instantiation. That delegate implements methods that I want the DelegateListener to call when the notifications that it subscribed to fire. The problem with this is that the instantiation of DelegateListener that I create gets released, unless if I assign it to a retained pointer. Is there a way to avoid this automatic release of my DelegateListener instantiation within ARC?

• php time 2 hours wrong for only 50% some users

  - by user1797802

  I am having huge issues with php time. For some reason it shows a different time (by 2 hours) to some users and the correct time to other users. The code is H:i:s d-M-y T when I view the page in a browser from my PC it tells me its 11am when infact its 9am, when I check via a browser using one my RDP's I get the correct time. Both PC's are in the country (uk) both PC's have the same system time etc. Tried setting the timezone default, but no matter what I do the server still shows some users the correct time, and other users the time 2 hour forward, any ideas? the code is echo gmdate("H:i:s d-M-y T"); <?php echo gmdate("H:i:s d-M-y T"); ?>

• how do I refactor this to make single function calls?

  - by stack.user.1

  I've been using this for a while updating mysql as needed. However I'm not too sure on the syntax..and need to migrate the sql to an array. Particulary the line database::query("CREATE TABLE $name($query)"); Does this translate to CREATE TABLE bookmark(name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT) This is my ...guess. Is this correct? class table extends database { private function create($name, $query) { database::query("CREATE TABLE $name($query)"); } public function make($type) { switch ($type) { case "credentials": self::create('credentials', 'id INT NOT NULL AUTO_INCREMENT, flname VARCHAR(60), email VARCHAR(32), pass VARCHAR(40), PRIMARY KEY(id)'); break; case "booomark": self::create('boomark', 'name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT'); break; case "tweet": self::create('tweet', 'time INT, fname VARCHAR(32), message VARCHAR(128), email VARCHAR(64)'); break; default: throw new Exception('Invalid Table Type'); } } }

• Perl - Choose interface to connect through

  - by Dieterve

  I have 2 interfaces on my server, eth0 and eth0:0. Those are 2 different external ips and obviously 2 different reverse domains. When i open a IO::Socket::INET Perl uses the eth0 interface by default. I would like to use the second interface (eth0:0) because this has a different ip and i dont want to use my main ip/domain. I have absolutely no idea how to select which interface to connect through. Code i use to open a socket: my $sock = new IO::Socket::INET(PeerAddr => $server, PeerPort => $serverPort, Proto => 'tcp') or die "Can't connect to server: $!";

• question about LocalSqlServer

  - by Alexander

  I know that by default ASP.NET ships with LocalSqlServer... I just uploaded my website and I did the following: <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=winsqlus03.lxa.perfora.net,1433; Initial Catalog=db323219488; User ID= dboxxxxxxxxx; Password=xxxxx;"/> And inside my App_Data I still have the ASPNETDB.MDF, when I tried to run it... What I got is: Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'. why is this?

• Bootstrap site mobile view not using full viewport

  - by jbarnett

  I'm currently making a responsive blog using the bootstrap 3.0 framework. I'm using the 1197 Max-width container for my content and it renders fine on desktops. However, when I try opening the site on my phone (I'm using an Android Galaxy Note 2), there is a lot of extra padding on the right and left sides of the viewport. I've tried following the API docs and guides as close as possible, but still can't get this to work. Here is the site I am working on http://www.justinbar.net Does anyone know what is going on with this? Am I doing something wrong, or do I need to override default behavior (which sounds a bit hacky to me).

• How do I remove line references in generate output in doxygen?

  - by MeThinks

  I want to remove lines look as follows but I still want to return source code browsing Definition at line 377 of file xxx.h. I have tried the following two in the doxygen config file but these just remove cross references on types # If the REFERENCES_RELATION tag is set to YES # then for each documented function all documented entities # called/used by that function will be listed. REFERENCES_RELATION = NO # If the REFERENCES_LINK_SOURCE tag is set to YES (the default) # and SOURCE_BROWSER tag is set to YES, then the hyperlinks from # functions in REFERENCES_RELATION and REFERENCED_BY_RELATION lists will # link to the source code. Otherwise they will link to the documentation. REFERENCES_LINK_SOURCE = NO update: I've just trying setting the following and seems to do the jobs but waiting to confirm if this is the correct way of achieving what I want SOURCE_BROWSER = NO

• jQuery finding 'nth-child' value

  - by Rich

  Hi, I have a ul set up as navigation, which I'll be animating on hover. As all the nav items are different widths, I'll be storing their default widths in an Array, so that on hover out, these widths can be passed back in to the animate method. What I need is a way to find what 'nth-child' the element is in order to retrieve the correct width from the array. Something like: var count = $(this).count(); //obviously this isn't right! So that then I can do: $(this).animate({'width':array(count)}, 400); Any suggestions would help me a lot - and if there's a better way to do this kind of thing I'd gladly accept pointers!

• Visual Studio C++ adds "junk" to my programs

  - by sub

  I have looked into the binaries produced by MSVC 2010 from my source code, and saw everything being filled with "junk". I don't know how to explain, but my executables are being added too much unnecessary information, like: Lots of Microsoft default error messages, I don't want them XML schema settings (Why!?) Other things not important for the execution of the main program How can I stop MSVC doing this? Do I have to switch to GCC? In all other programs (written in C++ too, from Word processors to games), this junk simply doesn't exist.

• What's the most performance effective way to have a webbrowser inside a class library ?

  - by Xaqron

  I'm developing a class library. Need some data from internet and this cannot be done with HttpWebRequest in my case so I wanna use WebBrowser component. WebBrowser is used for opening a single page and fetch some data from it, so WebBrowser life-time is very short. Running thread is MTA and no message pump or STA thread is available by default (class library is used by an ASP.NET application). How to create a WebBrowser object, run it with a STA thread, fetch data from a web page and finally dispose it with the least performance impact on the application ? I just need the idea/concept and will find details myself. Thanks guys

• AccountModel into a Repository and Interface

  - by Jemes

  I'm trying to separate the default AccountModel in mvc2 into a separate interface and repository. I've created an Interface and Repository and copied over the code from the AccountModel. I can register users and create accounts but in Visual Studio I'm getting the error below on the AccountController (* below).

• Cannot convert []string to []interface {}

  - by karlrh

  I'm writing some code, and I need it to catch the arguments and pass them through fmt.Println (I want its default behaviour, to write arguments separated by spaces and followed by a newline). However it takes []interface {} but flag.Args() returns a []string. Here's the code example package main import ( "fmt" "flag" ) func main() { flag.Parse() fmt.Println(flag.Args()...) } This returns the following error: ./example.go:10: cannot use args (type []string) as type []interface {} in function argument Is this a bug? Shouldn't fmt.Println take any array? By the way, I've also tried to do this: var args = []interface{}(flag.Args()) but I get the following error: cannot convert flag.Args() (type []string) to type []interface {} Is there a "Go" way to workaround this?

• Display (tier) prices with qty increments and taxes

  - by witrin

  I need to display (tier) prices based on the qty increments of a product. E.g. a simple product, with a regular price of 50¢, no taxes and qty increments of 20 should be displayed on product views with "$10 per 20". Without using taxes this should be quite easy. But there seems to be no "default" helper or model to do this with taxes enabled and different calulation algorithms (e.g. Mage_Tax_Model_Calculation::CALC_UNIT_BASE); expect for quotes in Mage_Tax_Model_Sales_Total_Quote_Tax and Mage_Tax_Model_Sales_Total_Quote_Subtotal. Did I miss something here, or do I have to write the business logic on my own? And how I would best encapsulate it?

  Say my code is as follows: <ul> <li><img /></li> <li> <ul> <li><img /></li> </ul> </li> </ul> I'm trying to set a default size for the first img tag, but not affect the second one. everything I do affects the other one as well. Currently I have tried: $('ul#gallery > li').find('img').css('width','650px'); $('ul#gallery > li img').css('width','650px'); among others, but nothing works.

• Linq to SQL DateTime values are local (Kind=Unspecified) - How do I make it UTC?

  - by ericsson007

  Isn't there a (simple) way to tell Linq To SQL classes that a particular DateTime property should be considered as UTC (i.e. having the Kind property of the DateTime type to be Utc by default), or is there a 'clean' workaround? The time zone on my app-server is not the same as the SQL 2005 Server (cannot change any), and none is UTC. When I persist a property of type DateTime to the dB I use the UTC value (so the value in the db column is UTC), but when I read the values back (using Linq To SQL) I get the .Kind property of the DateTime value to be 'Unspecified'. The problem is that when I 'convert' it to UTC it is 4 hours off. This also means that when it is serialized it it ends up on the client side with a 4 hour wrong offset (since it is serialized using the UTC).

• When open-sourcing a live Rails app, is it dangerous to leave the session key secret in source contr

  - by rspeicher

  I've got a Rails app that's been running live for some time, and I'm planning to open source it in the near future. I'm wondering how dangerous it is to leave the session key store secret in source control while the app is live. If it's dangerous, how do people usually handle this problem? I'd guess that it's easiest to just move the string to a text file that's ignored by the SCM, and read it in later. Just for clarity, I'm talking about this: # Your secret key for verifying cookie session data integrity. # If you change this key, all old sessions will become invalid! # Make sure the secret is at least 30 characters and all random, # no regular words or you'll be exposed to dictionary attacks. ActionController::Base.session = { :key => '_application_session', :secret => '(long, unique string)' } And while we're on the subject, is there anything else in a default Rails app that should be protected when open sourcing a live app?

What is the best way of getting the MethodInfo for the missing method? Thanks

• ASP.NET MVC - Custom object instantiation / providing with the Modelbinder?

  Is it possible to customize the object initiation / providing with the default ASP.NET MVC Modelbinder? <AcceptVerbs(HttpVerbs.Post)> _ Function EditObject(id As int, <Bind(Exclude:="Id")> obj As BLL.Object) As ActionResult End Function I would like to 'provide' obj to the modelbinder. (i don't want the Modelbinder to use New() and instantiate obj, but I want to deliver the object from a custom repository.) Is this possible? Edit: The loading from the repository should be done based on the id parameter of EditObject...

• Detect if the iframe content has loaded successfully.

  - by skinssay

  Hi, I have a widget that contains an iframe. The user can configure the url of this iframe, but if the url could not be loaded (it does not exists or the user does not have access to internet) then the iframe should failover to a default offline page. The question is, how can I detect if the iframe could be loaded or not? I tried subscribing to the 'load' event, and, if this event is not fired after some time then I failover, but this only works in Firefox, since IE and Chrome fires the 'load' event when the "Page Not Found" is displayed.

• Rails valiation among a three model relationship

  - by Andrew

  I'm working on a three model relationship with one aspect that I'm not sure how to approach. Here's the basic relationship: class Taxonomy has_many :terms # attribute: `inclusive`, default => false end class Term belongs_to :taxonomy has_and_belongs_to_many :photos end class Photo has_and_belongs_to_many :terms end This is pretty straightforward stuff except for one thing: A Taxonomy can be either 'Inclusive' or 'Exclusive'. Exclusive means the terms are mutually exclusive, Inclusive means they're not. So, if a Taxonomy is exclusive ie. taxonomy.inclusive = false, then there can only be one term from that taxonomy attached to a given photo. Now, I can handle this on the client-side without a problem, but I am not quite sure how to set up a validation on Photos (or somewhere else) that says basically: "validate that no more than one term from an exclusive taxonomy is associated with this record." Any ideas on how to do that?

• Does /boot safe on top of a lvm LV (logical volume)?

  - by fantoman

  Title already asked the question. More specifically, I read in some documents that logical volumes are nice in general but not for /boot in a linux system. They say that bootloaders don't understand LVM volumes, so create a separate partition for /boot out of lvm. I recently installed Ubuntu server (9.10) for my home server, but by default /boot is created in the LVM. Everything is fine now, but I am not sure it is safe to use /boot in LVM. Second question is do I really need a physical partition (volume)(pv) for /boot or is it equally fine if I put it into a logical volume (lv) on top of a single shared volume group. Thanks in advance.

How to add the access right of AccessSourceE again? If i have a particular value in x, then how do i know whether AccessSourceE is set or not?
