• Why do I get this error when I try to push my SQLite3 to Postgresql (via Taps) on Cedar Stack?

  - by rhodee

  I've done quite a bit of research on Heroku Dev Center and I am now looking to the community for help. Here is my problem. I can not push my db to Heroku Cedar Stack. I am trying to migrate a sqlite database to postgresql via Taps gem. When I am ready to deploy I run: bundle install --without production heroku run db:push I get the following result: Running db:seed attached to terminal... up, run.17 sh: db:seed: not found heroku run rake db:migrate And when I run the migration: heroku run rake db:migrate I get the following: Running rake db:migrate attached to terminal... up, run.18 rake aborted! No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb) /usr/local/lib/ruby/1.9.1/rake.rb:2367:in `raw_load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:2007:in `block in load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:2058:in `standard_exception_handling' /usr/local/lib/ruby/1.9.1/rake.rb:2006:in `load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:1991:in `run' /usr/local/bin/rake:31:in `<main>' Everytime I push to Heroku (git push heroku master) it fails because my gem file is attempting to install sqlite3 gem-even though its inside of the development and test groups in my Gemfile. My database.yml production environment still points to sqlite adapter even after I have run the following command successfully: heroku config:add BUNDLE_WITHOUT="test development" --app app_name_on_heroku Out of ideas. Please help. If its useful I can post results of my gemfile, heroku ps and logs. Cheers UPDATE: After following @John's direction I now receive the following terminal message.

• Square Bullet in XSL-FO

  - by Igman

  I am attempting to create a list in XSL-FO using a square bracket. I have been able to get it working using the standard unicode bullet character (&#8226;) but I just can't seem to get it working for square brackets. I have tried using &#9632;, but that does not seem to work. It is important that i can get the square bullets working because I am matching an existing file format.Any help in getting this working would be greatly appreciated. <fo:list-item-label end-indent="label-end()"> <fo:block>&#x2022;</fo:block> </fo:list-item-label>

  I have the following two code blocks. Code block 1 var checkboxes = $("div.c1 > input:checkbox.c2", "#main"); var totalCheckboxes = checkboxes.length; var checkedCheckboxes = checkboxes.filter(":checked").length; Code block 2 var totalCheckBoxes = $("div.c1 > input:checkbox.c2", "#main").length; var checkedCheckBoxes = $("div.c1 > input:checkbox.c2:checked", "#main").length; Which one of the above will be faster? Thanks, Rahul

• Javascript execution order

  - by zaf

  I want to give a static javascript block of code to a html template designer, which can be: either inline or external or both used once or more in the html template and each block can determine its position in the template relative to the other javascript code blocks. An example could be image banners served using javascript. I give code to template designer who places it in two places, once for a horizontal banner in the header and once for a vertical banner. The same code runs in both blocks but knowing their positions can determine if to serve a horizontal or a vertical image banner. Make sense?

• How can I make VS2010 behave like VS2008 w/r/t indentation?

  - by Portman

  Situation I have a plain text file where indentation is important. line 1 line 1.1 (indented two spaces) line 1.2 (indented two spaces) line 1.2.3 (indented four spaces) In Visual Studio 2008, when I pressed enter, the next line would also be indented four spaces. However, in Visual Studio 2010, when I press enter, the next line is indented one tab. Question Does anybody know where, in the mountain of preferences under Tools Options, I can return to the way that Visual Studio 2008 worked? Under Options Text Editor Plain Text Tabs, I see the following: If I select "None", then I get no indentation when I move to the next line. If I select "Block", then I get TAB indentation (even though the previous line is spaces). In Visual Studio 2008, my indentation is set to "Block", and I get spaces. I have no idea what "Smart" indenting is, or why it is disabled.

• CSS height problem. IE8 seems correct Firefox seems wrong. Any fix?

  - by user169867

  Below is a complete html page that shows the problem. The "myDiv" should be 22px in height (including the border). Item 1 should have a 1px space between its border and the divs border. In IE8 it is. In FF 3.6.2 though it is 24px and I can't understand why. Ultimately my goal is to get the same CSS to create the same result in both browsers. It's driving me crazy!

• How do you exclude folders on get operation for sourcecontrol in CruiseControl.NET

  - by Jon

  I have a cruisecontrol.net project which currently doesn't monitor a source safe project. It is forced manually. Within the source control block however I want to be able to exclude the 'get' operation of a certain folder. I know there is a ExclusionFilter feature on a source control block in the config file, but I think that this excludes the sub folder from being monitored not from being retrieved from the repository. Can anyone confirm this is the case, or help me find out how I can achieve this? I'm using CCNet 1.4 and SourceSafe

• Styling jQuery validation

  - by Steve

  When I have this, the div, which just has text in it, uses all the horizontal width it can, so there's trailing width after the text, which I can tell from the background color. errorElement: "div", errorPlacement: function(error, element) { error.insertBefore("#zzz"); When I use this, the width is the same as the text contained, but I cannot get each individual error (span) to be on a separate line via display: block. errorElement: "span", errorPlacement: function(error, element) { error.insertBefore("#zzz"); error.css("display", "block"); Is there another way to force a break on a span element?

• Asynchronous readback from opengl front buffer using multiple PBO's

  - by KillianDS

  I am developing an application that needs to read back the whole frame from the front buffer of an openGL application. I can hijack the application's opengl library and insert my code on swapbuffers. At the moment I am successfully using a simple but excruciating slow glReadPixels command without PBO's. Now I read about using multiple PBO's to speed things up. While I think I've found enough resources to actually program that (isn't that hard), I have some operational questions left. I would do something like this: create a series (e.g. 3) of PBO's use glReadPixels in my swapBuffers override to read data from front buffer to a PBO (should be fast and non-blocking, right?) Create a seperate thread to call glMapBufferARB, once per PBO after a glReadPixels, because this will block until the pixels are in client memory. Process the data from step 3. Now my main concern is of course in steps 2 and 3. I read about glReadPixels used on PBO's being non-blocking, will this be an issue if I issue new opengl commands after that very fast? Will those opengl commands block? Or will they continue (my guess), and if so, I guess only swapbuffers can be a problem, will this one stall or will glReadPixels from front buffer be many times faster than swapping (about each 15-30ms) or, worst case scenario, will swapbuffers be executed while glReadPixels is still reading data to the PBO? My current guess is this logic will do something like this: copy FRONT_BUFFER - generic place in VRAM, copy VRAM-RAM. But I have no idea which of those 2 is the real bottleneck and more, what the influence on the normal opengl command stream is. Then in step 3. Is it wise to do this asynchronously in a thread separated from normal opengl logic? At the moment I think not, It seems you have to restore buffer operations to normal after doing this and I can't install synchronization objects in the original code to temporarily block those. So I think my best option is to define a certain swapbuffer delay before reading them out, so e.g. calling glReadPixels on PBO i%3 and glMapBufferARB on PBO (i+2)%3 in the same thread, resulting in a delay of 2 frames. Also, when I call glMapBufferARB to use data in client memory, will this be the bottleneck or will glReadPixels (asynchronously) be the bottleneck? And finally, if you have some better ideas to speed up frame readback from GPU in opengl, please tell me, because this is a painful bottleneck in my current system. I hope my question is clear enough, I know the answer will probably also be somewhere on the internet but I mostly came up with results that used PBO's to keep buffers in video memory and do processing there. I really need to read back the front buffer to RAM and I do not find any clear explanations about performance in that case (which I need, I cannot rely on "it's faster", I need to explain why it's faster). Thank you

• fourier transform to transpose key of a wav file

  - by tbischel

  I want to write an app to transpose the key a wav file plays in (for fun, I know there are apps that already do this)... my main understanding of how this might be accomplished is to 1) chop the audio file into very small blocks (say 1/10 a second) 2) run an FFT on each block 3) phase shift the frequency space up or down depending on what key I want 4) use an inverse FFT to return each block to the time domain 5) glue all the blocks together But now I'm wondering if the transformed blocks would no longer be continuous when I try to glue them back together. Are there ideas how I should do this to guarantee continuity, or am I just worrying about nothing?

• Getting LEGEND tags to wrap text properly.

  - by DA

  Legend tags are always a nuisance as they don't adhere to a lot of CSS rules. I'm trying to get the text within a LEGEND tag to wrap using the typical solution of wrapping the text in the LEGEND with a span and setting the width and display: block. <legend> <span style="border: 1px solid blue; width: 250px; display: block"> This text should wrap if it gets longer than 250px in width </span> </legend> I thought this used to work In Firefox, but does not appear to work anymore in 3.6. Sample: http://jsbin.com/exeno/5 It still works in IE. Has anyone found a fix for this or is it just a matter of forgoing LEGEND tags and go back to H# tags?

• Parsing C#, finding methods and putting try/catch to all methods

  - by erdogany

  I know it sounds weird but I am required to put a wrapping try catch block to every method to catch all exceptions. We have thousands of methods and I need to do it in an automated way. What do you suggest? I am planning to parse all cs files and detect methods and insert a try catch block with an application. Can you suggest me any parser that I can easily use? or anything that will help me... every method has its unique number like 5006 public static LogEntry Authenticate(....) { LogEntry logEntry = null; try { .... return logEntry; } catch (CompanyException) { throw; } catch (Exception ex) { logEntry = new LogEntry( "5006", RC.GetString("5006"), EventLogEntryType.Error, LogEntryCategory.Foo); throw new CompanyException(logEntry, ex); } } I created this for this; http://thinkoutofthenet.com/index.php/2009/01/12/batch-code-method-manipulation/

• jquery question - addclass to element depending on active image in rotating banner

  - by whitman6732

  I have a banner that rotates a series of three images. The active one has a display:block, while the inactive have display:none. I'm trying to match the class for the active image with an tag so that I can add an "active" class to the a tag. Having some trouble writing that function. It's adding all of the classes for each of the img elements, regardless of whether they're being displayed or not... The html markup looks like this: <div id="banner-area"> <div class="clearfix" id="promo-boxes-nav"> <ul id="banner-tabs"> <li> <ul id="page-tabs"> <li><a class="t39" href="#">1</a></li> <li><a class="t42" href="#">2</a></li> <li><a class="t49" href="#">3</a></li> </ul> </li> <li class="last">&nbsp;</li> </ul> </div> <div id="banner-content"> <img class="t39" src="http://localhost:8888/1.png" style="position: absolute; top: 0px; left: 0px; display: none; opacity: 0;"> <img class="t42" src="http://localhost:8888/2.png" style="position: absolute; top: 0px; left: 0px; display: block; opacity: 1;"> <img class="t49" src="http://localhost:8888/3.png" style="position: absolute; top: 0px; left: 0px; display: none;opacity: 0;"> </div> </div> The function in its current form looks like this: $j(document).ready(function() { $j('#banner-content') .cycle({ fx: 'fade', speed: 300, timeout: 3000, next: '.t1', pause: 1 }); if($j('#page-tabs a').attr('class')) { $j('#banner-content img').each(function() { if($j(this).attr('display','block')) { var bcClass = $j(this).attr('class'); } $j('#page-tabs li a').each(function() { if($j('#page-tabs li a').hasClass(bcClass)) { $j(this).addClass(bcClass); } }); }); } })

• ISQL Perform instruction: after editadd editupdate of table vs. after add update of table

  - by Frank Computer

  INFORMIX-SQL 7.3 Perform Screens: According to documentation, in an "after editadd editupdate of table" control block, its instructions are executed before the row is added or updated to the table, whereas in an "after add update of table" control block, its instructions are executed after the row has been added or updated to the table, supposedly meaning that any instructions which would alter values of field-tags linked to table.columns would not be committed to the table, but field-tags linked to displayonly fields will change?.. However, when using "after add update of table" I placed instructions which alter values for field-tags linked to table.columns and their displayed and committed values also changed!.. I would have thought that an "after add update of table" would only alter displayonly fields.

• BitBlt code not working

  - by MusiGenesis

  I'm trying to use this code to draw a Bitmap directly onto a PictureBox: Bitmap bmp = (Bitmap)Bitmap.FromFile(@"C:\Users\Ken\Desktop\Load2.bmp"); Graphics grDest = Graphics.FromHwnd(pictureBox1.Handle); Graphics grSrc = Graphics.FromImage(bmp); IntPtr hdcDest = grDest.GetHdc(); IntPtr hdcSrc = grSrc.GetHdc(); BitBlt(hdcDest, 0, 0, pictureBox1.Width, pictureBox1.Height, hdcSrc, 0, 0, (uint)TernaryRasterOperations.SRCCOPY); // 0x00CC0020 grDest.ReleaseHdc(hdcDest); grSrc.ReleaseHdc(hdcSrc); but instead of rendering the Bitmap's contents it just draws a solid block of nearly-black. I'm pretty sure the problem is with the source hDC, because if I change SRCCOPY to WHITENESS in the above code, it draws a solid white block, as expected. Note: this next snippet works fine, so there's nothing wrong with the bitmap itself: Bitmap bmp = (Bitmap)Bitmap.FromFile(@"C:\Users\Ken\Desktop\Load2.bmp"); pictureBox1.Image = bmp;

  I'm using ANTLR 3.4 with simplecTreeParser example and want to give string input from main.c I'v modified input in main as mentioned bellow pANTLR3_UINT8 input_string = (pANTLR3_UINT8)"int a;"; input = antlr3StringStreamNew(input_string, ANTLR3_ENC_8BIT, sizeof(input_string),(pANTLR3_UINT8)"ABCD"); Apparently getting following error -end of input-(1) : error 3 : 23:1: declaration : ( variable | functionHeader ';' - ^( FUNC_DECL functionHeader ) | functionHeader block - ^( FUNC_DEF functionHeader block ) );, at offset 0, at : cannot match to any predicted input...

• Passing multiple codeblocks as arguments

  - by doctororange

  I have a method which takes a code block. def opportunity @opportunities += 1 if yield @performances +=1 end end and I call it like this: opportunity { @some_array.empty? } But how do I pass it more than one code block so that I could use yield twice, something like this: def opportunity if yield_1 @opportunities += 1 end if yield_2 @performances +=1 end end and: opportunity {@some_other_array.empty?} { @some_array.empty? } I am aware that this example could be done without yield, but it's just to illustrate. Thanks.

• Catch isn't working

  - by neoneye

  I'm baffled. What could be causing 'catch' not to be working and how do I fix it? <?php try { throw new Exception('BOOM'); error_log("should not happen"); } catch(Exception $e) { error_log("should happen: " . $e->getMessage()); } ?> Actual output [27-Apr-2010 09:43:24] PHP Fatal error: Uncaught exception 'Exception' with message 'BOOM' in /mycode/exception_problem/index.php:4 Stack trace: #0 {main} thrown in /mycode/exception_problem/index.php on line 4 Desired output should happen: BOOM PHP version 5.2.3 In php_info() I don't see anywhere exceptions could have been disabled. I have tried with "restore_exception_handler();" but that doesn't make the catch block working. I have also tried with "set_exception_handler(NULL);" but that neither make the catch block working. How do I get the desired output?

• Drupal: Create custom search

  - by Dr. Hfuhruhurr

  I'm trying to create a custom search but getting stuck. What I want is to have a dropdownbox so the user can choose where to search in. These options can mean 1 or more content types. So if he chooses options A, then the search will look in node-type P,Q,R. But he may not give those results, but only the uid's which will be then themed to gather specific data for that user. To make it a little bit clearer, Suppose I want to llok for people. The what I'm searching in is 2 content profile types. But ofcourse you dont want to display those as a result, but a nice picture of the user and some data. I started with creating a form with a textfield and the dropdown box. Then, in the submit handler, i created the keys and redirected to another pages with those keys as a tail. This page has been defined in the menu hook, just like how search does it. After that I want to call hook_view to do the actual search by calling node_search, and give back the results. Unfortunately, it goes wrong. When i click the Search button, it gives me a 404. But am I on the right track? Is this the way to create a custom search? Thx for your help. Here's the code for some clarity: <?php // $Id$ /* * @file * Searches on Project, Person, Portfolio or Group. */ /** * returns an array of menu items * @return array of menu items */ function vm_search_menu() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $name => $description) { $items['zoek/'. $name .'/%menu_tail'] = array( 'page callback' => 'vm_search_view', 'page arguments' => array($name), 'type' => MENU_LOCAL_TASK, ); } return $items; } /** * create a block to put the form into. * @param $op * @param $delta * @param $edit * @return mixed */ function vm_search_block($op = 'list', $delta = 0, $edit = array()) { switch ($op) { case 'list': $blocks[0]['info'] = t('Algemene zoek'); return $blocks; case 'view': if (0 == $delta) { $block['subject'] = t(''); $block['content'] = drupal_get_form('vm_search_general_form'); } return $block; } } /** * Define the form. */ function vm_search_general_form() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $key => $subject) { $options[$key] = $subject['desc']; } $form['subjects'] = array( '#type' => 'select', '#options' => $options, '#required' => TRUE, ); $form['keys'] = array( '#type' => 'textfield', '#required' => TRUE, ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Zoek'), ); return $form; } function vm_search_general_form_submit($form, &$form_state) { $subjects = _vm_search_get_subjects(); $keys = $form_state['values']['keys']; //the search keys //the content types to search in $keys .= ' type:' . implode(',', $subjects[$form_state['values']['subjects']]['types']); //redirect to the page, where vm_search_view will handle the actual search $form_state['redirect'] = 'zoek/'. $form_state['values']['subjects'] .'/'. $keys; } /** * Menu callback; presents the search results. */ function vm_search_view($type = 'node') { // Search form submits with POST but redirects to GET. This way we can keep // the search query URL clean as a whistle: // search/type/keyword+keyword if (!isset($_POST['form_id'])) { if ($type == '') { // Note: search/node can not be a default tab because it would take on the // path of its parent (search). It would prevent remembering keywords when // switching tabs. This is why we drupal_goto to it from the parent instead. drupal_goto($front_page); } $keys = search_get_keys(); // Only perform search if there is non-whitespace search term: $results = ''; if (trim($keys)) { // Log the search keys: watchdog('vm_search', '%keys (@type).', array('%keys' => $keys, '@type' => $type)); // Collect the search results: $results = node_search('search', $type); if ($results) { $results = theme('box', t('Zoek resultaten'), $results); } else { $results = theme('box', t('Je zoek heeft geen resultaten opgeleverd.')); } } } return $results; } /** * returns array where to look for * @return array */ function _vm_search_get_subjects() { $subjects['opdracht'] = array('desc' => t('Opdracht'), 'types' => array('project') ); $subjects['persoon'] = array('desc' => t('Persoon'), 'types' => array('types_specialisatie', 'smaak_en_interesses') ); $subjects['groep'] = array('desc' => t('Groep'), 'types' => array('Villamedia_groep') ); $subjects['portfolio'] = array('desc' => t('Portfolio'), 'types' => array('artikel') ); return $subjects; }
