• Pulling a timestamp from an XML feed with PHP but seem to be to many digits

  - by Craig Ward

  I am pulling a timestamp from a feed and it gives 12 digits (1269088723811). When I convert it, it comes out as 1901-12-13 20:45:52, but if I put the timestamp into http://www.epochconverter.com/ it comes out as Sat, 20 Mar 2010 12:38:43 GMT, which is the correct time. epochconverter.com mentions that it maybe in milliseconds so I have amended the script to take care of it using $mil = $timestamp; $seconds = $mil / 1000; $date = date('Y-m-d H:i:s', date($seconds)); but it still converts the date wrong, 1970-01-25 20:31:23. What am I doing wrong?

• bash bcmath functions

  - by Gordon

  I have two functions for GNU bc in a Bash script. BC_CEIL="define ceil(x) { if (x>0) { if (x%1>0) return x+(1-(x%1)) else return x } else return -1*floor(-1*x) }\n" BC_FLOOR="define floor(x) { if (x>0) return x-(x%1) else return -1*ceil(-1*x) }\n" echo -e "scale=2"$BC_CEIL$BC_FLOOR"ceil(2.5)" | bc Both functions work fine in interactive bc. bc does not seem to allow multiple functions on one line separated by ; though, so I have to echo -n | bc with newlines at the end of each function. The above output is 2.5, not the expected 3.0 that I get if I type it into bc -i myself. It seems that bash calls bc for each line of echo output, rather than echo'ing it all to a single instance. Is there any workaround for this?

• How can I redirect the output of Perl's system() to a filehandle?

  - by syker

  With the open command in Perl, you can use a filehandle. However I have trouble getting back the exit code with the open command in Perl. With the system command in Perl, I can get back the exit code of the program I'm running. However I want to just redirect the STDOUT to some filehandle (no stderr). My stdout is going to be a line-by-line output of key-value pairs that I want to insert into a mao in perl. That is why I want to redirect only my stdout from my Java program in perl. Is that possible? Note: If I get errors, the errors get printed to stderr. One possibility is to check if anything gets printed to stderr so that I can quite the Perl script.

• Upload image with Photoshop scripting

  - by cosmorocket

  Is that possible to upload an image from Photoshop (for example, an open image exported to jpeg) to some web place - REST service, FTP etc by using scripting features of Photoshop? For example - I have an image open in Photoshop and then execute some special script that sends an exported version of it to some place over the web. I saw something like this but it uses an automatically generated batch file that executes ftp command on Windows. I would like to use something more beautiful if it's possible. Or may be there are some info to know how to make a simple plugin for just this task. Thanks.

• Referencing Environment Variables in web.xml

  - by Udi Bar-On

  I'm pre-packaging a JSP web-app that relies on some file path settings found within web.xml. These settings are unknown at packaging time, because they reference a path the customer will set when deploying the entire application (of which the web-app is a management interface). It seems that the easiest way to avoid tokens and file modifications in my installer script, is to ask the user for an install location, set this location as an environment variable (e.g JAVA_HOME), and have web.xml always reference that variable. Is there a way to reference an environment variable value from within web.xml? Google searches lead to the J2EE method of SETTING environment variables from ejb xml files. This is not what I'm looking for. Thanks Udi

• Checking if iframe is ready to be written to

  - by Bilal Aslam

  A 3rd party script on my web page creates an iframe. I need to know when this iframe is ready, so I can manipulate its DOM. I can think of a hacky approach: repeatedly try to modify the iFrame's DOM, and return success when a change we make sticks between two attempts. For this to work, I would prefer a property I can check on the iframe repeatedly. Is there an alternative, cross-browser evented approach to knowing that the iframe is ready? E.g. can we redefine the onLoad function to call into our code (but I don't know if I can do this, since I didn't create the iframe).

• How do i fix this JS scope in GM_xmlhttpRequest

  - by acidzombie24

  When i run this code alert 2 shows 6 different href links. alert 3 shows the last href 6 times. How do i make it use the same object (linkdom aka thelink) as alert 2. NOTE: This is in a greasemonkey script { var linkdom = thelink; alert('2' + linkdom.getAttribute("href")); GM_xmlhttpRequest({ method: 'GET', url: href, onload: function(resp){ //... alert('3' + linkdom.getAttribute("href")); } }); //... }

• In Rails: How can I turn off caching for a particular activerecord database table?

  - by pmneve

  I have an associative table (scripts_runs) (has_many, through) that carries a status column ('started', 'ready to parse', 'completed' ). The started and ready to parse states are signaled by 'flag' files from distributed executions of the scripts pickedup periodically (20 seconds). The completed status is written directly to the associative table by the parser when it is done. With short scripts the complete status is written before the ready to parse flag file is picked up. Because the row from the table is cached, the complete status is not seen by the observer for the flag files and gets overwritten by the ready to parse status. This is not good. I need the status to be updated in the database in the correct sequence so an Ajax periodic query can inform the user of the status of each script and when the run ( consisting of one to many scripts ) is completed. Can I force the ScriptRun.find(:id) to always go to the database? If so how? If not, why not???

• UTF-8 BOM in php response to mootools xmlhttprequest

  - by Jimmy

  Hi, I'm writing my first little AJAX-enabled Joomla component. I'm using mootools. I got a xmlhttprequest to contact my Joomla component, and the component returns a response - just plain text echoed by php, like echo 'Hello World!'; It's all working fine, except wireshark tells me that the response is prepended with \357\273\277\357\273\277 when it gets read by the javascript on the client side. This shows up as a little square before the response in an alert box that the script shows. I don't explicitly set the encoding on the xmlhttprequest; mootools docs say that it defaults to UTF8. What's the right way to handle this? Should I be setting the encoding on the request? Mime type? Should the javascript get rid of it? I'm not planning to have any characters requiring UTF8 in the response, so using plain old ascii would be ok for me too. Thanks

• Why doesn't the highlighted part of the JavaScript work?

  - by Dor Cohen

  Why isn't the 'confirm password and password the same' part working? Meaning, the part that uses the 'getElementById' to adress the password and confirmpassword. Every part works but that particular part. It doesn't show a red box around the text fields. Can anyone help me? <html> <head> </head> <script> function submitinfo() { var firstname = document.getElementById("firstname").value; var lastname = document.getElementById("lastname").value; var username = document.getElementById("username").value; var password = document.getElementById("password").value; var confirmpassword = document.getElementById("confirmpassword").value; var email = document.getElementById("email").value; if(firstname !== "" && document.getElementById("firstname").style.borderColor == "red")     {     document.getElementById("firstname").style.border = "none"     } if(lastname !== "" && document.getElementById("lastname").style.borderColor == "red") { document.getElementById("lastname").style.border = "none" } if(username !== "" && document.getElementById("username").style.borderColor == "red") { document.getElementById("username").style.border = "none" } if(password !== "" && document.getElementById("password").style.borderColor == "red") { document.getElementById("password").style.border = "none" } if(confirmpassword !== "" && document.getElementById("confirmpassword").style.borderColor == "red") { document.getElementById("confirmpassword").style.border = "none" } if(email !== "" && document.getElementById("email").style.borderColor == "red") { document.getElementById("email").style.border = "none" } if(firstname == "") { document.getElementById("firstname").style.borderColor = "red"; document.getElementById("firstname").style.borderStyle = "solid"; } if(lastname == "") { document.getElementById("lastname").style.borderColor = "red"; document.getElementById("lastname").style.borderStyle = "solid"; } if(username == "") { document.getElementById("username").style.borderColor = "red"; document.getElementById("username").style.borderStyle = "solid"; } if(password == "") { document.getElementById("password").style.borderColor = "red"; document.getElementById("password").style.borderStyle = "solid"; } if(confirmpassword == "") { document.getElementById("confirmpassword").style.borderColor = "red"; document.getElementById("confirmpassword").style.borderStyle = "solid"; } if(email == "") { document.getElementById("email").style.borderColor = "red"; document.getElementById("email").style.borderStyle = "solid"; } if(password !== "" && confirmpassword !== "" && document.getElementById("password").style.border == "none" && document.getElementById("confirmpassword").style.border == "none" && password !== confirmpassword) { document.getElementById("password").style.border = "red"; document.getElementById("confirmpassword").style.border = "red"; } if(firstname && lastname && username && password && confirmpassword && email !== "") { window.open() } } </script> <h><font size=4 color=3BCCBE><b>Full Name</b></font><h/> <br> <input type="text" id="firstname" size="15px" placeholder="First"> <input type="text" id="lastname" size="15px" placeholder="Last"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Choose your username</b></font></h> <br> <input type="text" id="username" size="37px"> <br> <p><font size=3 color="grey">atleast 6 characters long</font></p> <br> <h><font size=4 color=3BCCBE><b>Create a password</b></font></h> <br> <input type="password" id="password" size="37px"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Confirm your password</b></font><h/> <br> <input type="password" id="confirmpassword" size="37px"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Email address</b></font><h/> <br> <input type="text" id="email" size="37px"> <br> <br> <br> <br> <input type="button" value="Submit" onclick="submitinfo()" style="height:50px; width:85px; font-size:22px;> <br> </body> </html>

• add schema to path in postgresql

  - by veilig

  I'm the process of moving applications over from all in the public schema to each having their own schema. for each application, I have a small script that will create the schema and then create the tables,functions,etc... to that schema. Is there anyway to automatically add a newly created schema to the search_path? Currently, the only way I see is to find the users current path SHOW search_path; and then add the new schema to it SET search_path to xxx,yyy,zzz; I would like some way to just say, append schema zzz to the users_search path. is this possible?

• How to fetch output when calling R using Qprocess or system

  - by SYK

  Hi Experts, I would like to execute a R script simply as R --file=x.R It runs well on the command line. However when I try the system call in C++ by QProcess::execute("R --file=x.R"); or system("R --file=x.R"); the program R runs and quits but I can't see the output the program is supposed to generate. If a program uses no stdout (such as R), how do I fetch the output after a system call either as a output file or in the program's own console? Thanks for your time.

• Calling C function from DTrace scripts

  - by dmeister

  DTrace is impressive, powerful tracing system originally from Solaris, but it is ported to FreeBSD and Mac OSX. DTrace uses a high-level language called D not unlike AWK or C. Here is an example: io:::start /pid == $1/ { printf("file %s offset %d size %d block %llu\n", args[2]->fi_pathname, args[2]->fi_offset, args[0]->b_bcount, args[0]->b_blkno); } Using the command line sudo dtrace -q -s <name>.d <pid> all IOs originated from that process are logged. My question is if and how it is possible to call custom C functions from a DTrace script to do advanced operations with that tracing data during the tracing itself.

• Conditional Validation using JQuery Validation Plugin

  - by Steve Kemp

  I have a simple html form that I've added validation to using the JQuery Validation plugin. I have it working for single fields that require a value. I now need to extend that so that if a user answers Yes to a question they must enter something in the Details field, otherwise the Details field can be left blank. I'm using radio buttons to display the Yes/No. Here's my complete html form - I'm not sure where to go from here: <script type="text/javascript" charset="utf-8"> $.metadata.setType("attr", "validate"); $(document).ready(function() { $("#editRecord").validate(); }); </script> <style type="text/css"> .block { display: block; } form.cmxform label.error { display: none; } </style> </head> <body> <div id="header"> <h1> Questions</h1> </div> <div id="content"> <h1> Questions Page 1 </h1> </div> <div id="content"> <h1> </h1> <form class="cmxform" method="post" action="editrecord.php" id="editRecord"> <input type="hidden" name="-action" value="edit"> <h1> Questions </h1> <table width="46%" class="record"> <tr> <td width="21%" valign="top" class="field_name_left"><p>Question 1</p></td> <td width="15%" valign="top" class="field_data"> <label for="Yes"> <input type="radio" name="Question1" value="Yes" validate = "required:true" /> Yes </label> <label for="No"> <input type="radio" name="Question1" value="No" /> No </label> <label for="Question1" class="error">You must answer this question to proceed</label> </td> <td width="64%" valign="top" class="field_data"><strong>Details:</strong> <textarea id = "Details1" class="where" name="Details1" cols="25" rows="2"></textarea></td> </tr> <tr> <td valign="top" class="field_name_left">Question 2</td> <td valign="top" class="field_data"> <label for="Yes"> <input type="radio" name="Question2" value="Yes" validate = "required:true" /> Yes </label> <label for="No"> <input type="radio" name="Question2" value="No" /> No </label> <label for="Question2" class="error">You must answer this question to proceed</label> </td> <td valign="top" class="field_data"><strong>Details:</strong> <textarea id = "Details2" class="where" name="Details2" cols="25" rows="2"></textarea> </td> </tr> <tr class="submit_btn"> <td colspan="3"> <input type="submit" name="-edit" value="Finish"> <input type="reset" name="reset" value="Reset"> </td> </tr> </table> </form> </div> </body> </html>

• How should I deploy a patch to a Passenger-based production Rails application without downtime?

  - by Olly

  I have a Passenger-based production Rails application which has thousands of users. Occasionally we need to apply a code patch (we use git) and the current process for doing this (you can assume there are no data migrations) is: Perform git pull origin [production-branch-name] on the server touch tmp/restart.txt to restart Passenger This allows us to patch the server without having to resort to putting up a maintenance page, which is great, but it doesn't feel quite right since it's not actually a proper 'deployment', and we still need to manually update the revision file and our deployment doesn't appear in the Hoptoad or NewRelic services we use. Ideally I would run cap production deploy and just let the standard Capistrano deployment script take care of everything, but is this a dangerous thing to do without putting up a maintenance page? This deployment process seems to be fairly safe in that the new revision is deployed to a completely separate folder and only right at the end of the process is a symlink re-created to switch the currently deployed version, but I'm still fairly paranoid about this somehow resulting in a lost or failed request.

• How can I perform a normal postback on an ASP.NET page with AJAX history enabled?

  - by Nick

  I have an ASP.NET 3.5 page with an update panel and history enabled. It works fine when I perform async postbacks but I get problems when I want to perform a normal postback. The page load happens fine for the normal postback but then I get asynchronous page loads from the script manager which load the ajax history in. If I could have the ajax history not loading for the times I want to perform a normal postback then everything would be fine. Is there anyway to do this?

• Tabexpansion function Does Not Resolve Variable

  - by chadwickmiller

  I'm attempting to override and implement my own TabExpansion. In the function I want to parse the contents of $psise.CurrentFile.Editor.Text when a certain $lastword criteria is matched. The issue I have is that the variable $psise.CurrentFile.Editor.Text is resolved to the contents of my TabExpansion function rather than whatever text is in a PowerShell ISE tab. Here's simple test function. Open an ISE tab and paste the following tabexpansion function definition: function tabexpansion { $psise.CurrentFile.Editor.Text } Run the script in ISE. Next open another tab in ISE type some text and press the tab key The output will be function tabexpansion { $psise.CurrentFile.Editor.Text } Rather than whatever text was in the second tab. Is there any way to get $psise.CurrentFile.Editor.Text to resolve at runtime when used within a tabexpansion function?

• HTTP Content-type header for cached files

  - by Brian

  Hello, Using Apache with mod_rewrite, when I load a .css or .js file and view the HTTP headers, the Content-type is only set correctly the first time I load it - subsequent refreshes are missing Content-type altogether and it's creating some problems for me. I can get around this by appending a random query string value to the end of each filename, eg. http://www.site.com/script.js?12345 However, I don't want to have to do that, since caching is good and all I want is for the Content-type to be present. I've tried using a RewriteRule to force the type but still didn't solve the problem. Any ideas? Thanks, Brian

• What should I do with syncobj in SQL Server

  - by hgulyan

  Hi. I run this script to search particular text in sys.columns and I get a lot of "dbo.syncobj_0x3934443438443332" this kind of result. SELECT c.name, s.name + '.' + o.name FROM sys.columns c INNER JOIN sys.objects o ON c.object_id=o.object_id INNER JOIN sys.schemas s ON o.schema_id=s.schema_id WHERE c.name LIKE '%text%' If I get it right, they are replication objects. Is it so? Can i just throw them away from my query just like o.name NOT LIKE '%syncobj%' or there's another way? Thank you.

• Why doesn't Inno Setup compiler set the version info correctly from hudson?

  - by Tim

  If I run Inno Setup compiler from a command line/batch file it creates an exe with the version information in the file name. However, when I run from hudson (same command line) I don't get the version information. Perhaps I am missing something. Is this a known issue? This is the way I am doing it in the iss script file. #define FileVerStr GetFileVersion(SrcApp) EDIT: The env vars are all set for all users - not just my login - so the service has access to everything that the command line build does. EDIT: See my answer for a resolution of this.

• How do I call exec in psake to an executable with a variable path?

  - by Josh Kodroff

  I can't seem to call this executable correctly in my psake deploy script. If I do this: exec { "$ArchiverOutputDir\NServiceBus.Host.exe /install" } It simply outputs this (and is clearly not calling the executable - just outputting the value of that expression): c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install But if I do this: exec { c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install } I get the expected output from the executable. How do I correctly call an executable with a variable in the path to the executable in psake? If this is actually a PowerShell issue, please feel free to correct the question to reflect that insight.

• Weird Facebooker Plugin & Pushion Passenger ModRails Production Error

  - by Ranknoodle

  I have an application (Rails 2.3.5) that I'm deploying to production Linux/Apache server using the latest Phushion Passenger/Apache Module 2.2.11 version. After deploying my original application, it returns a 500 error with no logging to production log. So I created a minimal test rails application, with some active record calls to the database to print out a list of objects to the home controller/my index page. I also cleared out all plugins. That works fine in the production environment. Then I one by one introduced each plugin that I'm using one at a time. Every plugin works fine EXCEPT facebooker. Every time I load the facebooker plugin into my app/vendor/plugins directory (via script git etc) my test application break (500 error - no error logging). Everytime I remove the facebooker plugin my test application works. Has anyone seen this before/ have any solutions? I saw this solution but didn't see it in the facebooker code.

• How to debug GWT using Ant

  - by Phuong Nguyen de ManCity fan

  I know that the job would be simpler if I use Google Plugin for Eclipse. However, in my situation, I heavily adapted Maven and thus, the plugin cannot suit me. (In fact, it gave me the whole week of headache). Rather, I relied on a ant script that I learned from http://code.google.com/webtoolkit/doc/latest/tutorial/appengine.html The document was very clear; I follow the article and successfully invoked DevMode using ant devmode. However, the document didn't tell me about debugging GWT (like Google Plugin for Eclipse can do). Basically, I want to add some parameter to an ant task that expose a debug port (something like (com.google.gwt.dev.DevMode at localhost:58807)) so that I can connect my eclipse to. How can I do that?
