• Cannot Enter Repro Admin Web Interface at Port 5080

  - by aqua

  I have followed the instructions on this website www.rtcquickstart.org to set up my firewall, DNS settings, TLS, and have installed the TURN server and repro proxy as instructed, and have restarted repro. However, I am not able to access the web interface of repro on port 5080, either at localhost:5080 / 127.0.0.1:5080 or at the server's IP address: IPADDRESS:5080 (I have set the server's IP for binding in repro.config). I get the browser error message: 'Unable to connect to server' whenever trying to connect to the web interface via port 5080. I initially had Apache2 installed, which loaded pages correctly at port 80 / address root, and when checked it 'listened' at port 5080 after it was configured in /etc/apache2/ports.conf, however the repro web interface still did not work at port 5080. I have tried uninstalling Apache2 in case that was conflicting with repro's web server, but the problem persists, and testing port 5080 now shows that nothing is 'listening' on port 5080. I have tried reinstalling / purging repro but it has not helped. My router is correctly set to allow all ports; port 5080 is open and forwarding correctly. I can connect to the internet and ping all websites through the server and everything else is working correctly. I would be gateful if anyone could offer advice on how to solve this problem.

• USB Ports In Wrong Mode, How To Use usbmodeswitch?

  - by user86872

  I haven't had access to my USB ports as media devices for a couple days now. I've been reading and researching everything I can find but I can't find a good guide for usbmodeswtich or usbms that I can decipher. The USB's are fine for power, but won't support my android phone as a media device, which is killing me because I use adb everyday, and won't support my plug and play mouse any longer. Not sure what caused the switch, though I think it may be related to the suspend issue I've read about, but the solutions in those threads I read also didn't work. Below is my system information and details. System: Ubuntu 12.04, 64-bit, Dedicated Machine Machine: HP-Pavillion g6 notebook, AMD A6 Quad Core Processor USBs used for: Cooling dock, Android Debug Bridge, Wireless Mouse Attempted Mod Probe, udev restart, unable to attempt lsusb due to my own lack of knowledge. :) Last Attempt Readout: ncandiano@ncandiano-HP-Pavilion-g6-Notebook-PC:~$ sudo modprobe -r usbhid && sleep 5 && sudo modprobe usbhid ncandiano@ncandiano-HP-Pavilion-g6-Notebook-PC:~$ sudo modprobe -r usb-storage ncandiano@ncandiano-HP-Pavilion-g6-Notebook-PC:~$ sudo modprobe usb-storage ncandiano@ncandiano-HP-Pavilion-g6-Notebook-PC:~$ sudo restart udev udev start/running, process 2624 ncandiano@ncandiano-HP-Pavilion-g6-Notebook-PC:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0461:4de7 Primax Electronics, Ltd webcam Any help would be greatly appreciated!

• Providing SSH tunnling, what to think about when configuring Ubuntu Server

  - by bigbadonk420

  Recently I've considered, mostly as a pet project, to set up accounts for a closed group of users via SSH to my box with the purpose of SSH tunnling things like web traffic -- some of it for friends that live abroad and perhaps also to help some people bypass national censorship. There's some things I imagine that I need to do, such as: Disabling shell access by setting the shell to /bin/false or similar. Get some software that can track bandwidth usage on a per-user basis historically Make sure that each user can only use a certain amount of bandwidth. The reason I'm posting here to begin with is to look around and get some pointers regarding what kind of things I should read up on, as well as hearing if there are any software recommendations for doing what I'm trying to do. I already know a bit since I've actually gotten SSH tunnling up and running already, I just don't feel like letting it loose to other people without restrictions and some basic monitoring. I'm primarily trying to learn here, so if you think this is a Very Bad Idea (or if you have a better idea on how to do this) then by all means say so, but please include some information on how to do it :) (I'm also open to trying things like OpenVPN but it seems really hard to set up, also I've heard SSH more often works in locked down environments)

• What to do when TDD tests reveal new functionality that is needed that also needs tests?

  - by Joshua Harris

  What do you do when you are writing a test and you get to the point where you need to make the test pass and you realize that you need an additional piece of functionality that should be separated into its own function? That new function needs to be tested as well, but the TDD cycle says to Make a test fail, make it pass then refactor. If I am on the step where I am trying to make my test pass I'm not supposed to go off and start another failing test to test the new functionality that I need to implement. For example, I am writing a point class that has a function WillCollideWith(LineSegment): public class Point { // Point data and constructor ... public bool CollidesWithLine(LineSegment lineSegment) { Vector PointEndOfMovement = new Vector(Position.X + Velocity.X, Position.Y + Velocity.Y); LineSegment pointPath = new LineSegment(Position, PointEndOfMovement); if (lineSegment.Intersects(pointPath)) return true; return false; } } I was writing a test for CollidesWithLine when I realized that I would need a LineSegment.Intersects(LineSegment) function. But, should I just stop what I am doing on my test cycle to go create this new functionality? That seems to break the "Red, Green, Refactor" principle. Should I just write the code that detects that lineSegments Intersect inside of the CollidesWithLine function and refactor it after it is working? That would work in this case since I can access the data from LineSegment, but what about in cases where that kind of data is private?

• How would I batch rename a lot of files using command-line?

  - by Whisperity

  I have a problem which I am unable to solve: I need to rename a great dump of files using patterns. I tried using this, but I always get an error. I have a folder, inside with a lot of files. Running ls -1 | wc -l, it returns that I have like 160000 files inside. The problem is, that I wish to move these files to a Windows system, but most of them have characters like : and ? in them, which makes the file unaccessible on said Windows-based systems. (As a "do not solve but deal with" method, I tried booting up a LiveCD on the Windows system and moving the files using the live OS. Under that Ubuntu, the files were readable and writable on the mounted NTFS partition, but when I booted back on Windows, it showed that the file is there but Windows was unable to access it in any fashion: rename, delete or open.) I tried running rename 's/\:/_' * inside the folder, but I got Argument list too long error. Some search revealed that it happens because I have so many files, and then I arrived here. The problem is that I don't know how to alter the command to suit my needs, as I always end up having various errors like Trying find -name '*:*' | xargs rename : _, it gives xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option [\n] syntax error at (eval 1) line 1, near ":" [\n] xargs: rename: exited with status 255; aborting Adding the -0 after xargs turns the error message to xargs: argument line too long These files are archive files generated by various PHP scripts. The best solution would be having a chance to rename them before they are moved to Windows, but if there is no way to do it, we might have a way to rename the files while they are moved to Windows. I use samba and proftpd to move the files. Unfortunately, graphical software are out of the question as the server containing the files is what it is, a server, with only command-line interface.

• Application toolkits like QT versus traditional game/multimedia libraries like SFML

  - by Aaron

  I currently intend to use SFML for my next game project. I'll need a substantial GUI though (RPG/strategy-type) so I'll either have to implement my own or try to find an appropriate third party library, which seem to boil down to CEGUI, libRocket, and GWEN. At the same time, I do not anticipate doing that many advanced graphical effects. My game will be 2D and primarily sprite-based with some sprite animations. I've recently discovered that QT applications can have their appearance styled so that they don't have to look like plain OS apps. Given that, I am beginning to consider QT a valid alternative to SFML. I wouldn't have to implement the GUI functionality I'd need, and I may not be taking advantage of SFML's lower-level access anyway. The only drawbacks I can think of immediately are the learning curve for QT and figuring out how to fit game logic inside such a framework after getting used to the input/update/render loop of traditional game libraries. When would an application toolkit like QT be more appropriate for a game than a traditional game or multimedia library like SFML?

• Electricsheep Not Working in Raring 13.04

  - by Nhoeh37

  I just downloaded Electricsheep four days before I updated my Ubuntu software and I fell in love with it. After I upgraded to 13.04, I'm kind of upset in saying that Electricsheep no longer works. I have no idea how to fix it and I feel helpless with Linux. As I said, it was working completely fine in 12.10, but now with the Raring Ringtail update: I use Xscreensaver to launch Electricsheep. When I open Xscreensaver, "Electricsheep" is one of the options to choose. When I "preview" ES or even launch the "xscreensaver-demo" in the terminal, it doesn't work anymore; I get an error message. The error message says: "detected another electric sheep process. rendering of sheep is disabled using read only access." Damnit, can someone please help me? I want my trippy screensaver back, it shouldn't be this hard! EDIT: I contacted the creator of Electricsheep (Scott Draves) via the link to his email address on his personal website and asked for his assistance. Hopefully the Askubuntu community will be able to fix this problem, I'm sure I am not the only one who is having this problem as I have searched and searched.

• Windows Defender Update KB915597 (Definition 1.135.415.0)? Killed My Live Discs

  - by user88311

  Here's my problem, for those willing to read for about 2 minutes here's the entire story, http://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_update/bsod-after-windows-defender-update-kb915597/a4b5fca3-0274-47b4-97c4-61b34c4c4599, for those who want the short version here's what happened. After windows update automatically updated windows defender to kb915597, my computer starting getting bsods on shut down and start up and started experiencing problems withe the usb ports. So I decided to go to the microsoft answers site for help, I know that was probably my first mistake, so I followed their advice and they turned my computer into a large paper weight. Luckily I make physical backups of my c drive every few months and I have one from back in july, so I figured I'd boot up a ubuntu live disc, copy all my files from the past 2 months to a external drive and just copy the backup back to the c drive, that's where I ran into this problem. When I put in either a ubuntu or kubuntu disc, everything goes well, until it finishes the loading bar then when the OS would presumably start up, the computer resets, I've tried with ubuntu, kubuntu and gparted, and only gparted is able to get to the point where it starts up, but even then when I try to access the internet from it, the computer resets, and when I tried to copy the entire C drive partition to a blank external I wasn't able to. So I figured somehow maybe the C drive had something to do with it, so I unplugged the C drive so my computer was just a 2.8 ghz processor and 2 gigs of ram, should have had no problem starting a live disc but the problem still continues. After doing some googling around I've found whenever windows gets a update with the title KB915597 it's pretty much the kill switch for windows, I've tried contacting microsoft tech support and even managed to directly contact a software engineer but as soon as I mention KB915597 they all just blew me off. I hope anybody who reads this has any idea how to fix this, I'm going to attempt to install ubuntu or kubuntu to a external drive using the same computer and see what happens now.

• How can I refresh/reinstall/clear/set-to-default my bootup process?

  - by Tchalvak

  I'm currently having a problem with my bootup process that is growing progressively worse as time goes on: While booting, it does a few minutes of hard-drive reading. During that, instead of showing a boot splash screen, it shows various dashes and dots, as if the video card isn't recognizing. The splash screen actually has colors similar to the splash screen (purple), it simply is garbled. It then does a few minutes of hard-drive reads, and if I leave it long enough, sometimes it boots into the desktop (and auto-logs-in). Sometimes, unfortunately, it just hangs on that garbled screen and reads from the hard-drive forever. Notably, I've also stopped being able to access grub during bootup (perhaps it is just not displayed correctly by the video, hard to tell). This is a symptom that has grown over the course of various ubuntu upgrades, at least I suspect that the upgrade process is leaving behind cruft. So, is there a safe way for me to "refresh" the boot system so that it is clean, new, fast, and reliable? For example, to test out a cleanly configured boot, make sure that it works (try before I buy), and then apply it to the system to eliminate as much of this problem as possible? Edit: Here is the requested bootchart: http://imgur.com/9jocF

• Introducing Code Map for Visual Studio 2012 September CTP

  - by krislankford

  As part of the Visual Studio 2012 CTP for September, Visual Studio got a little sexier at helping you discover and visualize your code. The introduction of the Code Map feature helps compliment the variety of other tools that are included with Visual Studio to help you analyze and visualize your projects and solutions. Code Map leverages the dgml format within Visual Studio that is currently used b the Architecture and Modeling tools. This is a nice addition that gets us from point A to point B a little faster. The great thing about Code Map is that you can gain access to the functionality from directly within your code from the context menu. This Code Map functionality is also context specific based on your cursor. You can evaluate and add items such as methods and variables directly to the Code Map window. As you add items the Code Map surface is updated to show your new item plus any relationships and dependencies that have been introduced in your code. Something that is also very nice is that the Code Map surface is interactive and allows you to use the F12 button (Go To Definition) which can help you navigate your code especially is you are adding items that span multiple files or projects. To get started all you have to do is go out and download the September CTP for Visual Studio 2012 located here. Happy Coding!   Code Map Window

• TechEd 2010 Day Four: Learning how to help others learn

  - by BuckWoody

  I do quite a few presentations, and teach at the University of Washington, and also teach other classes. But I'm always learning from others how to help others learn. At events like TechEd I have access to some of the best speakers around, so I try to find out what they do that works. I attended a great session by allen White, in which he demonstrated a set of PowerShell scripts. He said that Dan Jones of the Microsoft Manageability team told him while he demonstrated a script he needed to provide some visual way to represent the process. Allen used one of the oldest visualizations around - a flowchart. It was the first time I'd seen one used to illustrate a PowerShell script, and it was very effective. I'm totally stealing the idea. All of us are teachers - we help others on our team understand what we're up to. Make sure you make notes for what you find effective in dealing with you, and then meld that into your own way of teaching.

• ASP.NET MVC 3 (C#) Software Architecture

  - by ryanzec

  I am starting on a relatively large and ambitious ASP.NET MVC 3 project and just thinking about the best way to organize my code. The project is basically going to be a general management system that will be capable of supporting any type management system whether it be a blogging system, cms, reservation system, wikis, forums, project management system, etc…, each of them being just a separate 'module'. You can read more about it on my blog posted here : http://www.ryanzec.com/index.php/blog/details/8 (forgive me, the style of the site kinda sucks). For those who don't want to read the long blog post the basic idea is that the core system itself is nothing more than a users system with an admin interface to manage the users system. Then you just add on module as you need them and the module I will be creating is a simple blog post to test it out before I move on to the big module which is a project management system. Now I am just trying to think of the best way to structure this so that it is easy for users to add in there own modules but easy for me to update to core system without worrying about the user modifying the core code. I think the ideal way would be to have a number of core projects that user is specifically told not to modify otherwise the system may become unstable and future updates would not work. When the user wants to add in there own modules, they would just add in a new project (or multiple projects). The thing is I am not sure that it is even possible to use multiple projects all with their own controllers, razor view template, css, javascript, etc... in one web application. Ideally each module would have some of it own razor view templates, css, javascript, image files and also need access to some of the core razor view templates, css, javascript, image files which would is in a separate project. It is possible to have 1 web application run off of controllers, razor view templates, css, javascript, image files that are store in multiple projects? Is there a better was to structure this to allow the user to easily add in module with having to modify the core code?

• Is it possible to have multiple subdomains point to the same Blogger blog?

  - by cclark

  For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?

• Defining formula through user interface in user form

  - by BriskLabs Pakistan

  I am a student and developing a simple assignment - windows form application in visual studio 2010. The application is suppose to construct formulas as per user requirement. The process: It has to pick data from columns of Microsoft Access database and the user should be able to pick the data by column name like we do in a drop down menu. and create reusable formulas in it ( configure it once and can change it again). followings are column titles from database that can be picked for example. e.g Col -1 : Marks in Maths Col -2 : Total Marks in Maths Col -3 : Marks in science Col -4 : Total marks in science Finally we should be able to construct any formula in the UI like (Col 1 + Col 3 ) / ( col 2 + col 4) = Formula 1 once this is formula is set saved and a name is assigned to it by user. he/she can use the formula and results shall appear in a window below. i.e He would be able to calculate his desired figures (formula) by only manipulating underlying data on the UI layer....choose the data for a period and apply the formula and get the answer Problem: It looks like I have to create an app where rules are set through UI....... this means no stored procedures are required in SQL.... please suggest the right approach.

• mount ext4 formated external drive->the drives green light won't stop flashing

  - by Gohlool

  I've installed kubuntu (after 10 years I am trying to play with linux) and manged to attach a external 1TB HDD drive over USB! The drive was formatted with NTFS and everything was working OK. I also changed the /etc/fstab here is my ntfs mount setting: /dev/sdb1 /media/samsung nts-3g auto,user,uid=1000,gid=1000,fmask=000,utf-8 0, 0 Now, I've reparationed the drive and formated it with ext4 filesystem! change my fstb like: /dev/sdb1 /media/samsung ext4 defaults,noatime 0, 0 now, when I plug my dive/or call sudo mount -a, my external drive's green light starts to flash and won't stop, but mount works .... What is the Problem? is this because of ext4? because with NTFS this won't happen! btw. after changing the owner of the /media/samsung and setting permissions 777, I can also access my drive like creating new folder atc. (although is's flashing constantly)! What is my mistake? btw. can you please let me know how to set the owner and the permissions for my /media/samsung directory in fstab for ext4 like I did it for NTFS? Thanks in advance

• Web migration of a VB6 system with VWG

  - by Webgui

  Brinks Bolivia eSAC System (Customer Service) allows to register all different kinds of contacts for a customer; addition to maintaining an updated status of each service or customer request, to have accurate information and perform the appropriate procedures for all applications. The system was originally developed in VB6 and since web access was essential it was offered via Citrix. Since the application's performance was a critical issue as well as the need to offer the system without specific installations the company looked for a solution that would solve those drawbacks of using Citrix. Searching for a solution that would allow it to offer the eSAC system over the web without the need for specific client installations and provide sufficient performance levels even when there is limited bandwidth lead Brinks to a decision to migrate their VB6 Customer Service system to to Visual WebGui. "Developing on Visual WebGui we were able to migrate the system to web environment and even add new features in less time which allows us to offer it over a standard web browser with better performance and no installations as was required with Citrix," concluded Alexander Cuellar. The full article and screenshots of the system are available here.

• How is determined an impact of a requirement change on the existing code?

  - by MainMa

  Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.

• How to keep track of previous scenes and return to them in libgdx

  - by MxyL

  I have three scenes: SceneTitle, SceneMenu, SceneLoad. (The difference between the title scene and the menu scene is that the title scene is what you see when you first turn on the game, and the menu scene is what you can access during the game. During the game, meaning, after you've hit "play!" in the title scene.) I provide the ability to save progress and consequently load a particular game. An issue that I've run into is being able to easily keep track of the previous scene. For example, if you enter the load scene and then decide to change your mind, the game needs to go back to where you were before; this isn't something that can be hardcoded. Now, an easy solution off the top of my head is to simply maintain a scene stack, which basically keeps track of history for me. A simple transaction would be as follows I'm currently in the menu scene, so the top of the stack is SceneMenu I go to the load scene, so the game pushes SceneLoad onto the stack. When I return from the load scene, the game pops SceneLoad off the stack and initializes the scene that's currently at the top, which is SceneMenu I'm coding in Java, so I can't simply pass around Classes as if they were objects, so I've decided implemented as enum for eac scene and put that on the stack and then have my scene managing class go through a list of if conditions to return the appropriate instance of the class. How can I implement my scene stack without having to do too much work maintaining it?

• Notification framework for object lifecycle

  - by rlandster

  I am looking for an application, framework, or library that would help us with "object life-cycle management". There are many things that are created for users, departments, and services that, all too often, are left unmanaged. Some examples: user accounts groups SSL certificates access rights databases software license provisionings storage list-serve accounts These objects are created and managed by a wide variety of applications and systems. Typically, a user (person) requests (either explicitly or implicitly) one of these objects. A centralized management tool would help us manage such administration chores as: What objects does user X currently own/manage? Move the ownership of object P to user X; move all objects owned by user X (who was just been fired) to user Y. For all objects of type T that have expired be sure the objects have been disabled or deleted by their provider. How many active (expired, about-to-expire) objects of type P are there? Send periodic notifications to all users who own active objects of type P reminding them of what they own. There is a security alert for objects of type P; send a notification to all users who own these types of objects to take a specific remedial action. Delete or disable a set of objects based on expiration (or some other criteria). These objects are directly managed through their own applications (Active Directory, MySql, file systems, etc.) and may even have their own notification systems, but I want to centralize this into an "object management system". The OMS should allow the association with an external identity provider that defines who the users and groups are (e.g., LDAP, Active Directory) creation of objects association of an object to a specific user and/or group association with an expiration date creation of flexible reporting including letting users know what objects they currently own and their expiration dates integration with an external object "provider" via a plug-in We could write something from scratch, but I am hoping there is something already out there that will help, either an entire application or a set of libraries that provide much of what is needed. Any ideas?

• recent unreliable wireless connection

  - by gabkdlly

  Recently, my internet connection over wireless ( via a Netgear KWGR614 router ) has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista, nor on a Desktop running Windows 7 ( this machine is connected with an ethernet cable ). The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP or WPA to encrypt the wireless network. Is it possible that someone is jamming my signal ?

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.
