• How to remove compiler flag when building Boost

  - by mlo

  I need to build Boost with a non-standard set of flags (due to a conflict between Boost threading and C++/CLI). I'm adding the required flag (/clr) using CXXFLAGS, but this flag conflicts with the Boost default /EHs flag (/clr implies /EHa which is incompatible with /EHs), so that needs to be suppressed. Is there a mechanism like CXXFLAGS to suppress a default Boost flag or must I edit all of the compiler specification files by hand?

• Reloading an object not working in rspec

  - by Eric Baldwin

  I am trying to test a controller method with the following code: it "should set an approved_at date and email the campaign's client" do @campaign = Campaign.create(valid_attributes) post :approve, id: @campaign.id.to_s @campaign.reload @campaign.approved_at.should_not be(nil) end However, when I run this test, I get the following error: Failure/Error: @campaign.reload ActiveRecord::RecordNotFound: Couldn't find Campaign without an ID When I run the analagous lines in the rails console, the reload works and the value is set as I need it to be. Why isn't reload working for me when I run the code in an rspec test?

• Opening a streaming connection to an HTTP server on iPhone/Cocoa environment?

  - by Paul

  I've been using NSURLConnection to do a HTTP post to establish the connection. I've also implemented the didReceiveData delegagate to process incoming bytes as they become available. As incoming data comes in via didReceiveData, I add the NSData to a data buffer and try parsing the bytesteam if enough data has come in to complete a message segment. I'm having a hard time managing the data buffer (NSMutableData object) to remove bytes that have been parsed to structs. Was curious if there's an easier way. Thanks

• jquery: Flash messages

  - by Svish

  With jQuery, how can I display a flash message at the top of the page in an easy way? Is there something built-in, or a plugin, or is it easy enough to do it yourself? What I mean is like after a successful ajax post I would like to just say "hey, it went good" in a non-obtrusive way.

• What data type to use for variable length data (for performance)?

  - by jiewmeng

  What data type should I use for data that can be very short, eg. html link (think twitter), or very long eg. html blog post (think wordpress). I am thinking if I use varchar(4000), it maybe too short for a html formated blog entry? but if I use text, it will take up more space and is less efficient?

• Unlimited Online File Storage

  - by AmeL

  Well, I would like to build a file hosting website just like other already did, but it is going to be something different by adding search engine, allowing download and upload in full speed for any user, and so on. Unfortunately the web hosting plans, which declared to support UNLIMITED SPACE rarely allows me to host files on those space. So what I need is the unlimited file storage service which could host all of my users' files. I found Amazon S3, already provides such service, but could anybody recommends me for other better ?

• Display "custom" view (various images, various text). Should I use UIWebView?

  - by aw

  First: No, none of the content should be loaded from the web. All content parts are shipped with the main bundle. I have n images and mass of text (including lists). Instead of building all view parts programmatically in objective-c if was thinking of using an UIWebView and build "only" the HTML dynamically. Does anything speaks against it? How does UIWebView work with local content? Links and resources welcome. Thanks

  I'd like to automate a 'screenshot' of arbitary URL's using a Linux build that doesn't have X installed. There appears to be some (costly) web services to do this, but I specifically want something I can do locally. Tried imagemagick without much success, though Mozilla used to have a command line option to do it?

• Javascript text insertion in textbox.

  - by Guru

  Hello there, I've got a textbox(id="tb1") and a button(id="btn1"). I want that whenever I click on btn1 a text "hello world" must be inserted in the tb1 at the current position of cursor in text-box. Please provide me a cross browser solution for this.
