  • DEADLOCK_WRAP error when using Berkeley Db in python (bsddb)

    - by JiminyCricket
    I am using a berkdb to store a huge list of key-value pairs but for some reason when i try to access some of the data later i get this error: try: key = 'scrape011201-590652' contenttext = contentdict[key] except: print the error <type 'exceptions.KeyError'> 'scrape011201-590652' in contenttext = contentdict[key]\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in __getitem__\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n', 'File "/usr/lib64/python2.5/bsddb/dbutils.py", line 62, in DeadlockWrap\n return function(*_args, **_kwargs)\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in <lambda>\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n'] I am not sure what DeadlockWrap is but there isnt any other program or process accessing the berkdb or writing to it (as far as i know,) so not sure how we could get a deadlock, if its referring to that. Is it possible that I am trying to access the data to rapidly? I have this function call in a loop, so something like for i in hugelist: #try to get a value from the berkdb #do something with it I am running this with multiple datasets and this error only occurs with one of them, the largest one, not the others.

  • PHP - Short hand if statement with a date format with weird output.

    - by McNabbToSkins
    I am using a short hand notation of an if statement to format a field. If the field is an empty string I leave it as an empty string, if not then I am trying to format it to a proper datetime format so it can be inserted into a mysql db. here is my php code $date = ($date == '') ? date("Y-m-d", strtotime($date)) : $date; for some reason when the $date string is not empty it is returning it int he format 'm/d/Y' example: 04/01/2010 When I pull the code out of the shorthand if $date = date("Y-m-d", strtotime($date)); print($date); it is formatted correctly like this 'Y-m-d' or 2010-04-01. Does anyone know why this happens? Thanks

  • gwt typeahead missing

    - by arinte
    I have a GWT app with a bunch of textboxes. In firefox I would expect that when I type a word in a textbox that I have already typed in and submitted, that firefox would offer to autocomplete that text. But for this GWT app it is not happening. Also in IE it seems that none of my css stuff is loaded. And when I IE developer tools on my GWT page, it can focus in on any of the textboxes it just focuses on the encompassing DIV around all the textboxes.

  • -webkit- vs -moz-transition

    - by danixd
    I am using CSS3 transitions on my site and the -webkit- seems to be working, whilst the -moz- is not. Here is the CSS: article {z-index: 2; float: left; overflow: hidden; position: relative; -webkit-transition: -webkit-transform 0.2s ease-in-out; -moz-transition: -moz-transform 0.2s ease-in-out; } .mousedown{-webkit-transform: translate(-180px, 0) !important; -moz-transform: translate(-180px, 0) !important; } Just using jQeury to add the mousedown class onto the article. Any idea where I am going wrong?

  • Positioning a tooltip relative to another div in JQuery

    - by James P
    Here's my tooltips markup and CSS: <div class="tooltip">Click here to like it</div> .tooltip { position: absolute; display: none; background: url('images/tooltip.gif') no-repeat; width: 100%; height: 40px; font-size: 0.8em; line-height: 40px; padding: 0px 0px 0px 8px; } Now, I have a div on my page called #button_container. I would like to place this .tooltip div 150px to the right of that div via JQuery. I understand I need to set this tooltips top and left attributes, but not sure how. Idealy the tooltips top attribute should be the same as #button_container (although #button_container isn't positioned absolutely) and 150 less than #button_container's left attribute. I don't really know where to get started on this so any help would be very much appreciated. Thanks.

  • How to set the content of the $script_for_layout in cakephp?

    - by sipiatti
    Hi, I am learning cakephp in an autodidact manner and I am a complete newbie :) I am creating a simple application. Some logic work so now I going to dive into designing views and layouts. I read the docs and the tutorial but I could not find where to set the content of $script_for_layout. Especially I want to set a $html-css to create link in pages to the stylesheet. I found out that I could do it in directly in the layout template but I would like to create the same link in all pages/views/layouts to the stylesheet so I hope there is a simple way, and avoid to do this in all layouts and/or controllers

    hi, function ip_address_to_number($IPaddress) { if(!$IPaddress) { return false; } else { $ips = split('\.',$IPaddress); return($ips[3] + $ips[2]*256 + $ips[1]*65536 + $ips[0]*16777216); } } that function executes the same code as the php bundled function ip2long. however, when i print these 2 values, i get 2 different returns. why? (im using php 5.2.10 on a wamp environment). ip2long('200.117.248.17'); //returns -931792879 ip_address_to_number('200.117.248.17'); // returns 3363174417

  • Code jumps out of a jar and runs? What is causing this?

    - by Mike
    I am trying to get a sample program working with JUNG, a graphing tool in Java. I downloaded and referenced all the .jar files in eclipse so my project hierarchy looks like this: In Test.java I have the following code: public class Test { static public void main() { System.out.print("Hello"); }} For some reason though when I try to run it as a Java Application by right clicking on Jung test in the project hierarchy I am presented with a bunch of classes. My Test.java isn't on the list so if I just leave it as ** and press ok it starts running a program that is dynamically adding nodes and vertexes to a graph. I can't seem to figure out what code its actually executing. I know java but stuff like this with the jar files seems to be getting lost on me. Any ideas? Thanks

  • How can I see what capybara found in a failing cucumber step?

    - by ajmurmann
    I started migrating from cucumber + webrat to cucumber + capybara. Now the behavior of "I should see " seems to be somewhat different. Most of these fail now, although I didn't change anything on the page. I replaced the snippet that should be found with some stuff that is on every page and for some text it works and for other text it doesn't. I can't find any pattern in what is found in the page's content and what is not. Webrat used to print what the page content is that it found, in case it did not contain the required phrase. Is there anyway to have capybara show what text it got from the page in which it tried to find the text?

  • SDL_ttf and Numbers (int)

    - by jack moore
    int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, fixedscore, fColor ); ^^ This doesn't work - looks like fixedscore is empty or doesn't exists. int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, "Works fine", fColor ); ^^ Works fine, but... I guess converting int to char* doesn't really work. So how do you print scores in SDL? Oh and one more thing: why is the text so ugly? Any help would be appreciated. Thanks.

  • jQuery Audio Player

    - by tony noriega
    I was given 2 MP3 files, one that is 4.5Mb and one that is 5.6Mb. I was instructed to have them play on a website i am managing. I have found a nice, clean looking CSS based jQuery audio player. My question is, is this the right solution for files that big? I am not sure if the player preloads the file, or streams it ? (if that is the correct terminology) i dont deal much with audio players and such... this player is from happyworm.com/jquery/jplayer/latest/demo-01.htm is there another approach i shoudl take to get this to play properly? I dont want it to have to buffer, and the visitor to wait, or slow page loading...etc..etc.. i want it to play clean and not affect the visitors session to the site. thanks

  • Python: Trying to get index of an intersection

    - by user1620716
    I have the following line of code: for i in [i for i,x in enumerate(catdate) if x == set(NNSRCfile['datetimenew']).intersection(catdate)]: print i I am trying to find the index of the intersection for the two components above. Both are lengthy lists that have several commonalities. The intersection part works perfectly; however, the for loop seems to output nothing. (ie: there is nothing that is printed). Python outputs no error, and when I run the code in IPython, I notice that i is equivalent to to the very last element in the list "catdate", instead of listing the indices of "catdate" that are equivalent to the intersection values. Any help is greatly appreciated!

  • Checking whether an object exists in StructureMap container

    - by Kevin Pang
    I'm using StructureMap to handle the creation of NHibernate's ISessionFactory and ISession. I've scoped ISessionFactory as a singleton so that it's only created once for my web app and I've scoped ISession as a hybrid so that it will only be opened once per web request. I want to make sure that at the end of each web request, I properly dispose of ISession if it was created for that web request. I figured I could put some code in my Application_EndRequest routine to first check if an ISession was created, and if so, call ISession.Dispose. My current workaround is to just open up an ISession on Application_BeginRequest then dispose of it on Application_EndRequest, but that seems somewhat wasteful in that static file requests for images and css files and whatnot will create an ISession without ever using it. I know that the overall performance hit is negligable since ISessions are very lightweight, but it's getting annoying seeing all those ISessions being created inside NHProf.

  • How to place text on top of image in ReportViewer

    - by Christoffer
    I feel very silly asking this, since it seems like it just should work, but I cannot make it work and cannot find anything in the documentation about this. The problem: I'm developing an application in Visual Studio 2010 that is utilizing ReportViewer, rendering the report locally. In the report designer, I place a textbox on top of an image. This looks fine in the designer, but when rendering the report, the textbox is rendered below the image. Now, before you suggest it, I have tried placing a textbox on top of a rectangle (or other control) with the BackgroundImage property set. This works. But: I cannot find a way to rescale the background image to fit the control. Setting a different dpi for the background image does nothing. Simply rescaling the image to a different resolution is not an option, since I eventually want to print the report. Does anybody have a solution to this?

  • How can I transition from a front-end career to back-end career?

    - by jexx2345
    Hello, In 2004, I received my B.S. in Computer Science using mostly Java for programming. Since then, I have been hired for purely front-end positions in large companies through recruiters, doing primarily HTML/CSS, Javascript/jQuery, and OOP Actionscript 3. While I definitely have respect for the front-end, and have learned much, I feel very unfulfilled and would love to move into back-end for the more complex programming I was doing in school. My target platform of choice is ASP.Net 3.5 (C#). With a resume that has absolutely no .Net or back-end experience, how can I transition into a junior back-end job? I am currently freelancing a .Net e-commerce site, and plan to build a portfolio showcasing some apps (e-commerce mvc, blog, etc), while learning the technology. Is having a Bachelors in CS enough or should I look into getting .Net certified? Is showing course-work still relevant to an employer even though it was from 6 years ago? Thank you

  • PHP, MySQL, jQuery, AJAX: json data returns correct response but frontend returns error

    - by Devner
    Hi all, I have a user registration form. I am doing server side validation on the fly via AJAX. The quick summary of my problem is that upon validating 2 fields, I get error for the second field validation. If I comment first field, then the 2nd field does not show any error. It has this weird behavior. More details below: The HTML, JS and Php code are below: HTML FORM: <form id="SignupForm" action=""> <fieldset> <legend>Free Signup</legend> <label for="username">Username</label> <input name="username" type="text" id="username" /><span id="status_username"></span><br /> <label for="email">Email</label> <input name="email" type="text" id="email" /><span id="status_email"></span><br /> <label for="confirm_email">Confirm Email</label> <input name="confirm_email" type="text" id="confirm_email" /><span id="status_confirm_email"></span><br /> </fieldset> <p> <input id="sbt" type="button" value="Submit form" /> </p> </form> JS: <script type="text/javascript"> $(document).ready(function() { $("#email").blur(function() { var email = $("#email").val(); var msgbox2 = $("#status_email"); if(email.length > 3) { $.ajax({ type: 'POST', url: 'check_ajax2.php', data: "email="+ email, dataType: 'json', cache: false, success: function(data) { if(data.success == 'y') { alert('Available'); } else { alert('Not Available'); } } }); } return false; }); $("#confirm_email").blur(function() { var confirm_email = $("#confirm_email").val(); var email = $("#email").val(); var msgbox3 = $("#status_confirm_email"); if(confirm_email.length > 3) { $.ajax({ type: 'POST', url: 'check_ajax2.php', data: 'confirm_email='+ confirm_email + '&email=' + email, dataType: 'json', cache: false, success: function(data) { if(data.success == 'y') { alert('Available'); } else { alert('Not Available'); } } , error: function (data) { alert('Some error'); } }); } return false; }); }); </script> PHP code: <?php //check_ajax2.php if(isset($_POST['email'])) { $email = $_POST['email']; $res = mysql_query("SELECT uid FROM members WHERE email = '$email' "); $i_exists = mysql_num_rows($res); if( 0 == $i_exists ) { $success = 'y'; $msg_email = 'Email available'; } else { $success = 'n'; $msg_email = 'Email is already in use.</font>'; } print json_encode(array('success' => $success, 'msg_email' => $msg_email)); } if(isset($_POST['confirm_email'])) { $confirm_email = $_POST['confirm_email']; $email = ( isset($_POST['email']) && trim($_POST['email']) != '' ? $_POST['email'] : '' ); $res = mysql_query("SELECT uid FROM members WHERE email = '$confirm_email' "); $i_exists = mysql_num_rows($res); if( 0 == $i_exists ) { if( isset($email) && isset($confirm_email) && $email == $confirm_email ) { $success = 'y'; $msg_confirm_email = 'Email available and match'; } else { $success = 'n'; $msg_confirm_email = 'Email and Confirm Email do NOT match.'; } } else { $success = 'n'; $msg_confirm_email = 'Email already exists.'; } print json_encode(array('success' => $success, 'msg_confirm_email' => $msg_confirm_email)); } ?> THE PROBLEM: As long as I am validating the $_POST['email'] as well as $_POST['confirm_email'] in the check_ajax2.php file, the validation for confirm_email field always returns an error. With my limited knowledge of Firebug, however, I did find out that the following were the responses when I entered email and confirm_email in the fields: RESPONSE 1: {"success":"y","msg_email":"Email available"} RESPONSE 2: {"success":"y","msg_email":"Email available"}{"success":"n","msg_confirm_email":"Email and Confirm Email do NOT match."} Although the RESPONSE 2 shows that we are receiving the correct message via msg_confirm_email, in the front end, the alert 'Some error' is popping up (I have enabled the alert for debugging). I have spent 48 hours trying to change every part of the code wherever possible, but with only little success. What is weird about this is that if I comment the validation for $_POST['email'] field completely, then the validation for $_POST['confirm_email'] field is displaying correctly without any errors. If I enable it back, it is validating email field correctly, but when it reaches the point of validating confirm_email field, it is again showing me the error. I have also tried renaming success variable in check_ajax2.php page to other different names for both $_POST['email'] and $_POST['confirm_email'] but no success. I will be adding more fields in the form and validating within the check_ajax2.php page. So I am not planning on using different ajax pages for validating each of those fields (and I don't think it's smart to do it that way). I am not a jquery or AJAX guru, so all help in resolving this issue is highly appreciated. Thank you in advance.

  • Pure-JavaScript projects in NetBeans?

    - by Matt Zukowski
    This seems like it ought to be obvious, yet I can't figure it out. I do a lot of JavaScript coding, and I really like NetBeans. Unfortunately I can't figure out how to create a "JavaScript" project in NetBeans. If I go to File - New Project, my only options are "Java", "Ruby", and "NetBeans Modules". I don't want any of these. My project consists mostly of JavaScript, with a little bit of CSS. I ususally just end up creating a "Ruby" project, but this seems retarded, since I don't actually have any Ruby code. Why isn't there an option to create a "JavaScript" or "Web" project, or at least a "Generic" project that doesn't revolve around a specific language? Am I missing something here?

  • Track/Display Array Index As Part Of Cout (C++)

    - by John Smith
    Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

  • Expand and collapse a div

    - by user494118
    I have a list of itens and they are holding images, each image is 800w x 600 H. The original div height is 800 W x 300 H, I figured out how to expand the div when it is clicked, but i want to know how to collapse it when you click it while it is already expanded. right now it just expands the div even farther $('.expand').bind('click', function() { var currHeight = $(this).css('height').replace(/px/,''); currHeight = currHeight * 1; var newHeight = currHeight + 500; $(this).animate({ height: newHeight },1000); }); any idea on how to create an if else statement that would say, IF the div is already expanded then collapse on click, or if the div is not expanded, expand to # of px.

  • Using XSL-FO and HTML?

    - by buggy1985
    Hi, I'm trying to transform some XML-data to HTML with XSLT for my bachelor thesis. My professor wants me to consider XSL-FO too, or at least to write some word about it. But I'm very noob to this. So my questions are: Can I combine FO with HTML? Can I use FO istead of HTML and CSS? If yes, how will my browser render this? Are there any examples/tutorials on how to transform xml into web pages with FO? Thank you very much.

  • How can I vertically center an element with GWT?

    - by Camille
    Perhaps I haven't been searching the right way but I cannot figure out for the life of me how to center an element using GWT Layout Panels. I'm using UiBinder and I've tried all panels that implement HasVerticalAlignment (DockPanel, HorizontalPanel, VerticalPanel). None of them seem to have any impact from setting vertical alignment (or even horizontal). I've made sure they're taking 100% width and height, inspected the resulting DOM layout from my browser and nothing seems to be changed from those properties. The quick and dirty fix I've figured out is to create my own "CenterPanel" widget which basically is a wrapper around a HTMLPanel with a HTML table with a valign="middle" cell. However, this basically feels like a throwback to the classical css-layout middle centering problems. Surely GWT has something to do this that I've completely overlooked?

  • Parallel Assignment operator in Ruby

    - by Bragaadeesh
    Hi, I was going through an example from Programming in Ruby book. This is that example def fib_up_to(max) i1, i2 = 1, 1 # parallel assignment (i1 = 1 and i2 = 1) while i1 <= max yield i1 i1, i2 = i2, i1+i2 end end fib_up_to(100) {|f| print f, " " } The above program simply prints the fibonacci numbers upto 100. Thats fine. My question here is when i replace the parallel assignment with something like this, i1 = i2 i2 = i1+i2 I am not getting the desired output. My question here is, is it advisable to use parallel assignments? (I come from Java background and it feels really wierd to see this type of assignment) One more doubt is : Is parallel assignment an operator?? Thanks
