• The conventional location for storing my Java libraries and applications in UNIX based systems

  - by Bytecode Ninja

  I usually store the Java applications and JAR files that I download from the Web in the ~/Java folder on my computer (an OS X machine). I have been doing this since the days when I was a Windows user. However I think in UNIX based systems user local apps are conventionally stored in another directory. I have a feeling that this directory should either be /usr/local/, /usr/local/USERNAME, /opt/local, or /opt/local/USERNAME but I am not sure. Any ideas which directory can I use for this purpose? Please note that, I am talking about archive files that I download from the Web, unpack and use locally and not programs that have installation scripts or MacPorts, etc.

• Why am I getting a TypeError when looping?

  - by Lee Crabtree

  I'm working on a Python extension module, and one of my little test scripts is doing something strange, viz.: x_max, y_max, z_max = m.size for x in xrange(x_max): for y in xrange(y_max): for z in xrange(z_max): #do my stuff What makes no sense is that the loop gets to the end of the first 'z' iteration, then throws a TypeError, stating that "an integer is required". If I put a try...except TypeError around it and check the types of x, y, and z, they all come back as < type 'int' . Am I missing something here?

• sql server db deployment script ignoring constraints etc until commit

  - by Daniel

  Hi all, I am planning on doing a database deployment script for sql server 2005. Currently we have a tool that will run all of the tables, foreign keys, indexes and then data, each of which is located in a separate file with a certain extension (eg. tab, .kci, .fky) and the tool just runs *.tab, *.kci, *.fky into the db etc. Could I possibly combine all of thse into one file and have them run ignoring referential integrity until they are all complete, I would turn it on before we started inserting test data. It is just unmanageable having to maintain 4 or 5 different types of scripts for one table. Are there any issues I should be aware of? Cheers

• On Linux do people chroot a Java Web Application or use IPTables and run as non-root?

  - by Adam Gent

  When you run a Java Servlet Container that you would like to serve both static and dynamic content on port 80 you have the classic question of whether to run the server as: As root in hopefully a chroot jail if you can (haven't gotten this working yet) As a non root user and then use IPTables to forward port 80 to some other port (1024) that the container is running on Both: As a non root user, IPTables, and chroot jail. The problem with opt. 1 is the complexity of chrooting and still the security problems of running root.The problem with opt. 2 is that each Linux distro has a different way of persisting IPTables. Option 3 of course is probably idea but very hard to setup. Finally every distro has the annoying differences in daemon scripts. What do people find as the best distro agnostic solution and are there resources to show how to do this?

• Is file_get_contents multi line?

  - by Abs

  Hello all, Does file_get_contents maintain line breaks? I thought it did but I have tried this: if($conn){ $tsql = file_get_contents('scripts/CreateTables/SLR05_MATCH_CREATETABLES.sql'); $row = sqlsrv_query($conn, $tsql); print_r(sqlsrv_errors()); } The errors I get is that SQL Server complains that there is incorrect syntax. I get the same errors when I run the SQL Script without any line breaks, which suggests file_get_contents removes them? When I run the script normally (open the file in SQL Server Management Studio) and execute it, it works perfectly. So is there something that I can use that maintains line breaks etc? Or is there another problem here in using queries from a file with the SQL Server PHP Driver from Microsoft? Thanks all for any help

• Javascript: why I cannot load my external js page in Drupal ?

  - by Patrick

  hi, when I add the tag script to load an external javascript file, my page is not longer displayed. There are not error in Firebug, there are not errors such as "File not found" or "Not enough permissions", the browser just displays a blank page for some reason. <?php print $head; ?> <?php print $styles; ?> <?php print $scripts; ?> <script type="text/JavaScript" src="main.js" /> If I remove the last line everything works perfectly. The previous php lines are the standard Drupal head lines. This is the content of my js file: $(document).ready( function() { alert("hello"); }); thanks

• Template approach for a PHP application

  - by Industrial

  Hi everyone, We're in the middle of making a new e-commerce related PHP application and we have come to the point where we have started to think about how we should solve templating for our customers needs. What we would like to do is offer our customers the possibility of uploading/modifying templates to suit their company:s profile. The initial thought is that we shall not reinvent the wheel, so instead letting our customers upload their templates with FTP, so there will be basic HTML skills required. For those customers that want to modify/customize template and doesnt have the knowledge, we offer that service as well. I know that there's a number of issues to solve before this could be considered safe, like preventing XSS and writing scripts that check through each uploaded file for potential security threats and so on. Of course, there are some part that probably will be to complex for the customer to modify by themselves, so maybe this approach won't apply to all<< template files in the frontend application. But besides that, what would be a good way to handle this?

• Can events fired from an iframe be handled by elements in its parent?

  - by allyourcode

  Suppose I have a page located at www.example.com/foo, and it contains an iframe with src="http://www.example.com/bar". I want to be able to fire an event from /bar and have it be heard by /foo. Using the Prototype library, I've tried doing the following without success: Element.fire(parent, 'ns:frob'); When I do this, in ff 3.5, I get the following error: Node cannot be used in a document other than the one in which it was created" code: "4 Line 0 Not sure if that's related to my problem. Is there some security mechanism that's preventing scripts in /bar from kicking off events in /foo?

• Will Emacs --batch run in cron will hang when require user input?

  - by J Spen

  I have a job in crontab that requires emacs --batch but if the file is currently open it requests (s, p, q) to (steal, quit, etc...) which is fine if this file is being edited to not run the script but I want to make sure it kills the cron running script so it's not sitting in the background taking up memory. I have the output set to go to a log file so I can see this happening but no way to tell whether the script was terminated even though asked for user input. Does cron terminate these scripts and how to check the PID to make sure?

• Override properties block when including a psake script in an other psake script

  - by DanceAlot

  I am new to psake and I have this issue: I have 2 psake scripts: (1): base_tasks.ps1: properties{ $a = "hello" $b = "hi" } task One{ Write-Host $a } (2): install.ps1 Include .\base_tasks.ps1 properties{ $a = "Goodbye" $b = "Adjeu" } task default -depends One Now, is it possible to override the properties and variables from file 1? I want to use file 1 as "base tasks" and use the tasks in the install.ps1 and override the properties. Or do I have to do that an other way? I will invoke install.ps1 and use my $a and $b from install.ps1. DanceAlot

• How to find that 'runas' execution finished?

  - by Radek

  I use ruby 1.9.3p194 (2012-04-20) [i386-mingw32] on Windows7 To do mySQL backup I run runas /savecred /user:yogurt\administrator "cmd.exe /k mysqldump --user=#{dbuser} --password=#{dbpassword} #{dbname} > #{dump}" - mysqldump must be executed as administrator. I do not run my ruby scripts under administrator account. runas starts new cmd.exe and ruby doesn't wait for it to finish. Dump process takes about one minute to finish. After that I zip the dump file and delete it. But I have to make sure that the dump process already finished before I do any other action on that file. Right now I use sleep(60) that works but I wonder if there any better more systematic solution.

• Can a function defined in a bookmarklet be called from a page-level script?

  - by Soviut

  I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

• Running python/ruby script on iPhone?

  - by prosseek

  From the recent news from the Apple, I learned that one has to use C/C++/Objective-C for iPhone App. Accordingly, it's not possible to use MacPython or similar to make iPhone App. But as the python/ruby interpreter itself is written in C, isn't it OK to make python/ruby interpreter for iPhone to run the scripts on iphone? Is this possible? Does Apple support this? Or does someone implemented this? Or, the user should hack to do this?

• ASP.NET MVC 2 project default script files. What do you use?

  - by Andrew Florko

  Many js files are included into Scripts folder by default in ASP.NET MVC 2 Projects. I suppose developers use jquery library nearly every time they program a site, but what about other files? Please, can you tell scenarios and reasons when you: Use Microsoft.Ajax instead of jquery or mix both libraries? Do you use JQuery validation infrastructure instead of asp.net mvc one, or combine them both? Thank you in advance! P.S. there are also diferrent editions of the same file. Do you include different editions depenending on debug/release build?

• Figuring out the resource a lock in SQL Server 2000 affects

  - by Michael Lang

  I am adding a simple web-interface to show data from a commercial off the shelf (COTS) application. This COTS issues locks on any record the user is actively looking at (whether they intend to edit and update it or not). I have found sp_lock and the Microsoft sp_lock2 scripts and can see the locks, so that's all well and good. However, I cannot figure out how I can tell if a specific record I am about to update has been affected by one of these locks. If I submit the update request and there is in fact a lock, the web-interface will wait indefinitely until the user closes the window in the COTS. How can I either: a) determine before issuing an update that the record has been locked OR b) issue an update that will immediately return with a LOCKED status rather than indefinitely waiting on the COTS user to close their window on that record?

• How do I know if my PHP application is using too much memory?

  - by John

  I'm working on a PHP web application that let's users network with each other, book events, message etc... I launched it a few months ago and at the moment, there's only about 100 users. I set up the application on a VPS with ubuntu 9.10, apache 2, mysql 5 and php 5. I had 360 Mb of RAM, but upgraded to 720 MB a few minutes ago. Lately, my web application has been experiencing outages due to excessive memory usage. From what I can tell in error logs, it seems the server automatically kills apache processes that consume too much memory. As a result, I upgraded memory from 360 MB to 720 MB as a stop-gap measure. So my question is, how do I go about resolving these outage issues? How do I know if my website's need for more memory is due to poor code or if it's part of the website's natural growth? What's the most efficient way to determine which PHP scripts consume the most memory?

• 'Best' way to pull data relative to a div?

  - by acidzombie24

  This answer suggested i should put my data in JS instead of a textarea. Thinking about it i could have scripts and do something like myarray[i]="data" where i is the index of my for loop. However when i click a div how do i find out what i is? I have used var data = $(this).parent('.parent').find('.valuestr').eq(0).val(); which is extremely simple. Should i use a script or should i continue to do it with a textarea? if i should use a script 1) Whats the easiest way to find i and 2) Is it bad pratice to have dozens or hundreds of <script> in my html? or i can go through the loop twice but i still dont know the easiest way to find i. I would have to store it somewhere or go through multiple tags and count them.

• What would be the simplest way to deal with a text file using JSP?

  - by Nano Taboada

  First and foremost I should acknowledge that I have no experience at all using Java ServerPages, but I'm positive about achieving this task if you guys help me out a bit since it doesn't seem like something difficult for a seasoned JSP programmer. Anyway the thing is, there's an actual running JSP application within a *NIX box which I somewhat administer with kind of good permissions. The idea is to create a new but dead simple JSP page to control some Korn Shell scripts I've got running there. So the goal is to make some sort of HTML form that will be writing some kind of scriptStatus.on / scriptStatus.off file: #!usr/bin/ksh # coolScript.sh # This is my cool script that is being launched by cron every 10 minutes. if [ -e scriptStatus.off ] then # monitor disabled else # monitor enabled fi which then can be checked for existence within the running script, therefore allowing to easily activate / deactivate it without actually have do deal with cron. Please let me know if all this does make any sense and don't hesitate to ask as much questions as needed. Thanks much in advance!

• How to make sure the value is reset in foreach loop in PHP

  - by kwokwai

  Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

• Looking for a new PHP website framework

  - by Glycerine

  I built many a website, and my own 'custom' framework is just a general box of scripts cobbled together with loose ideas. I would love to progress to a framework which allows me to pass it onto the client for freedom. Someone suggested using wordpress but I'm not sure how general this can be. A current site I need to build is a fancy kitchen company, price lists, flash gallery (with backend driven pics) and well designed home. How could I bend the the will of wordpress? Alternatively, does anyone have a suggestion for an alternative. Thanks in advance guys -

• jquery not working in mvc after publishing to server

  - by czuroski

  Hello, I've built an mvc application which contains some jquery code. When I run the app from my ide, everything works perfectly. When I publish to the server and open the page, the jquery does not work. I get object expected errors. Could this be due to my file mappings? here is a sample of my mapping in the app - <script type="text/javascript" href="../../Scripts/jquery-1.3.2.js"></script> I published the app to iis7 successfully, but the jquery is broken. I did publish to an application within an existing web site. Any thoughts?

• PHP: producing relative date/time from timestamps

  - by KeyStroke

  Hi, I'm basically trying to convert a Unix timestamp (the time() function) to a relative date/time that's both compatible with past and future date. So outputs could be: 2 weeks ago 1 hour and 60 minutes ago 15 minutes and 54 seconds ago after 10 minutes and 15 seconds First I tried to code this, but made a huge unmaintainable function, and then I searched the internet for a couple of hours, yet all I can find are scripts that produce only one part of the time (e.h: "1 hour ago" without the minutes). Do you have a script that already does this? If so, I'd really appreciate if you could share it. Thanks.

• How can I know when SQL Full Text Index Population is finished?

  - by GarethOwen

  We are writing unit tests for our ASP.NET application that run against a test SQL Server database. That is, the ClassInitialize method creates a new database with test data, and the ClassCleanup deletes the database. We do this by running .bat scripts from code. The classes under test are given a connection string that connects to the unit test database rather than a production database. Our problem is, that the database contains a full text index, which needs to be fully populated with the test data in order for our tests to run as expected. As far as I can tell, the fulltext index is always populated in the background. I would like to be able to either: Create the full text index, fully populated, with a synchronous (transact-SQL?) statement, or Find out when the fulltext population is finished, is there a callback option, or can I ask repeatedly? My current solution is to force a delay at the end the class initialize method - 5 seconds seems to work - because I can't find anything in the documentation.

• error reporting issues

  - by SunnyOne

  I'm still entangled in error handling problems. After having read and tried lots of different scripts, I still do not have an overall insight on the problem. I made a syntax error on purpose and get the following error message : Parse error: syntax error, unexpected '{' in /home/directory/public_html/mypage.php on line 10 To understand how it work, as a first step, I'd like to remove this message(which I'am able to do) and replace it by a custom one. How can I customize this message ? Thanks a lot.
