  • How to generate the EC2 cerificate

    - by user192048
    While setting up the EC2 access, it seems I need two files, the private key and ec2 certificate. $ export EC2_PRIVATE_KEY=~/.ec2/pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem $ export EC2_CERT=~/.ec2/cert-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem However, I did not find anywhere I could download or create the key. from the documentation: The command line tools need access to the private key and X.509 certificate you generated after signing up for the Amazon EC2 service. I probably missed that, Is it possible to generate it again

  • Allocation of memory with LE routines

    - by HaWe
    At /questions/2000777/allocation-of-memory-in-variable-length-tables NealB mentioned LE routines to allocate/deallocate memory in a non-CICS COBOL program. I'd very much like to know how this is done: how the LE routine is called. (I'm familiar with the LINKAGE SECTION and with SET ADDRESS.) Since I have no access to an IBM mainframe at the moment - meaning no access to online documentation - some code snippets could enlighten me.

  • AES and CBC in PHP

    - by Kane
    I am trying to encrypt a string in php using AES-128 and CBC, but when I call mcrypt_generic_init() it returns false. $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '',MCRYPT_MODE_CBC, ''); $iv_size = mcrypt_enc_get_iv_size($cipher); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $res = mcrypt_generic_init($cipher, 'aaaa', $iv); //'aaaa' is a test key Can someone tell me why is returning 0/false? I read the php documentation and seems correct (http://us.php.net/manual/en/mcrypt.examples.php)

  • How does the Ableton warp algorithm work exactly?

    - by pepperdreamteam
    I'm looking for any documentation or definitive information on Ableton's warp feature. I understand that it has something to do with finding transients, aligning them with an even rhythm and shifting audio samples accordingly. I'm hoping to find ways to approximate warping with more basic audio editing tools. I understand that this is ableton's unique device, really any information about how it works would be helpful. So...does anyone have any 411?

  • admobad problem on iphone

    - by dubbeat
    Hey, I want to know if there's a few folks out there with experience in using admob for iphone apps. I've just started using it and have a problem. When I close an in app ad the actual ad itself has moved up 40 pixels and is mostly hidden behind the navigation bar. In addition all of my own content is shifted up 40 pixels. The addmob documentation is very limited so not much help there sadly.

  • iOS: how to understand the role of rootviewcontroller and its relationship with other objects

    - by Anthony Kong
    I have created a UISplitViewController based iOS app in XCode 3.2.5 Below is a screen shot of Interface builder showing the rootviewcontroller and how it is linked to other objects. Being a beginner myself, I do not understand: 1) What is the role of the rootviewcontroller? Searched the documentation but what I found did not answer this question. 2) I thought a IBOutlet should only link to one corresponding object. Why in this case the rootviewcontroller is linked to two?

  • Testcase with multitouch on Android?

    - by makke
    The TouchUtils class in the android documentation has functions like drag() [http://developer.android.com/intl/de/reference/android/test/TouchUtils.html#drag(android.test.InstrumentationTestCase,%20float,%20float,%20float,%20float,%20int)], but they do not support multi touch gestures, like a two finger swipe. Looking at the MotionEvent.obtain() methods, there does not seem to be any way of invoking a "virtual" multi touch event from a testcase. Anyone has got it working?

  • How to set visibility for textblocks in QTextEdit?

    - by serge
    Hi everyone, i tried to hide textblock's in QTextEdit, but it doesn't work: block = textedit.document().begin() block.setVisible(False) This code works fine for QPlainTextEdit, but not for QTextEdit. In documentation i haven't found any mention of how it should work for QTextEdit, just following: void QTextBlock::setVisible ( bool visible ) Sets the block's visibility to visible. This function was introduced in Qt 4.4. See also isVisible(). How can i hide block's in QTextEdit? Thank you in advance

  • How can I configure apigee to fail stale if the backend is unavialble?

    - by Anurag Kapur
    We have an API proxy configured with cache ttl of 2mins. Is it possible to configure apigee to serve stale cached content if the backend goes down so that our end users don't see errors? We would rather have our end users get copies of stale cached content (even after the configured ttl of 2mins expires) instead of errors when the backend goes down. Would appreciate if someone could point me to the relevant documentation if this is possible.

  • Need simple Twitter API v1.1 example to show timeline using jQuery or C# ASP.NET

    - by Ken Palmer
    With Twitter turning off the API 1.0 faucet on 6/11/2013, we have several sites that now fail to display timelines. I've been looking for an "If you did that, now do this" example. Here was Twitter's announcement. https://dev.twitter.com/blog/api-v1-is-retired Here is what we were originally doing to show the Twitter timeline via API 1.0. <div id="twitter"> <ul id="twitter_update_list"></ul> <script type="text/javascript" src="http://twitter.com/javascripts/blogger.js"></script> <script type="text/javascript" src="http://api.twitter.com/1/statuses/user_timeline/companytwitterhandle.json?callback=twitterCallback2&amp;count=1"></script> <div style="float:left;"><a href="https://twitter.com/companytwitterhandle" target="_blank">@companytwitterhandle</a> | </div> <div class="twitterimg">&nbsp;</div> </div> Initially I tried changing the version in the JavaScript reference URL like so, which did not work. <script type="text/javascript" src="http://api.twitter.com/1.1/statuses/user_timeline/companytwitterhandle.json?callback=twitterCallback2&amp;count=1"></script> Then I looked at the Twitter API documentation (https://dev.twitter.com/docs/api/1.1/overview) which lacks a clear transition example. I don't have 4 or 5 hours to delve into that, or into this disheveled FAQ (https://dev.twitter.com/docs/faq#17750). Then I found this API documentation regarding the user timeline. So I changed the URL again as shown below. https://dev.twitter.com/docs/api/1.1/get/statuses/user_timeline <script type="text/javascript" src="https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=companytwitterhandle&amp;count=1"></script> That did not work. Using jQuery or C# ASP.NET MVC, how can I transition that interface from Twitter API 1.0 to Twitter API 1.1? My first preference would be for a browser client side implementation if that is possible. Please include a code example. Thanks.
