• Network wide rule to forwared IP address

  - by Patrick

  Hi, we have a virtual machine which hosts a web based bug tracker in our network which is reached internally via e.g. 192.168.1.5:9800. From the outside we made a port forwarding in our firewall so that the web site can be reached via e.g. 72.10.10.10:9800. Now that works fine but the problem is that we got different IP addresses to reach the same service depending if we are in the office or at home and when the service sends out an email the link doesn't always work :) So we are looking for a solution to fix it. One could be to make a rule in out firewall that all communication to 72.10.10.10:9800 is forwarded to 192.168.1.5:9800... If that's possible that is considering it's an IP address + a port. The reason we used a port is because we only got one static public IP address but multiple virtual web appliances. Thanks for any suggestions or solutions :) Patrick PS: The network is a Win 2008 R2 domain by the way

• Is Tax Localization a good use for Workflow Foundation?

  - by JustinDoesWork

  Scenario: We have both Winforms and MVC code that is being used to work on a nation wide multi-user platform that does lots of logistics for lots of users. Tax rules change per state and even per city or county. These tax rules make a huge difference for our industry. The other issue is that rules can change based on legislation. The system will have to handle cases where before a date it works one way and then different after that date. This changeover will need to be entered into the system and tested before that date comes. Proposed Solution: Use Workflow Foundation to create a time based system where our users can change and add rules that change the way taxes are calculated. Question: I have not used Workflow Foundation and searching has returned books to look at but not a lot of examples of people using this technology successfully. Is my scenario a good use of Workflow Foundation?(I think so.) If you have any experience with Workflow Foundation, any tips on making this work well?

• Tunneling traffic through two VPN hops/tunnels.

  - by Roberto Sebestyen

  I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

• 2D Procedural Terrain with box2d Assets

  - by Alex

  I'm making a game that invloves a tire moving through terrain that is generated randomly over 1000 points. The terrain is always a downwards incline like so: The actual box2d terrain extends one screen width behind and infront of the circular character. I'm now at a stage where I need to add gameplay elements to the terrain such as chasms or physical objects (like the demo polygon in the picture) and am not sure of the best way to structure the procedural generation of the terrain and objects. I currently have a very simple for loop like so: for(int i = 0; i < kMaxHillPoints; i++) { hillKeyPoints[i] = CGPointMake(terrainX, terrainY); if(i%50 == 0) { i += [self generateCasmAtIndex:i]; } terrainX += winsize.width/20; terrainY -= random() % ((int) winsize.height/20); } With the generateCasmAtIndex function add points to the hillKeyPoints array and incrementing the for loop by the required amount. If I want to generate box2d objects as well for specific terrain elements, I'll also have to keep track of the current position of the player and have some sort of array of box2d objects that need to be created at certain locations. I am not sure of an efficient way to accomplish this procedural generation of terrain elements with accompanying box2d objects. My thoughts are: 1) Have many functions for each terrain element (chasm, jump etc.) which add elements to be drawn to an array that is check on each game step - similar to what I've shown above. 2) Create an array of terrain element objects that string together and are looped over to create the terrain and generate the box2d objects. Each object would hold an array of points to be drawn and and array of accompanying box2d objects. Any help on this is much appreciated as I cannot see a 'clean' solution.

• Scene Graph for Deferred Rendering Engine

  - by Roy T.

  As a learning exercise I've written a deferred rendering engine. Now I'd like to add a scene graph to this engine but I'm a bit puzzled how to do this. On a normal (forward rendering engine) I would just add all items (All implementing IDrawable and IUpdateAble) to my scene graph, than travel the scene-graph breadth first and call Draw() everywhere. However in a deferred rendering engine I have to separate draw calls. First I have to draw the geometry, then the shadow casters and then the lights (all to different render targets), before I combine them all. So in this case I can't just travel over the scene graph and just call draw. The way I see it I either have to travel over the entire scene graph 3 times, checking what kind of object it is that has to be drawn, or I have to create 3 separate scene graphs that are somehow connected to each other. Both of these seem poor solutions, I'd like to handle scene objects more transparent. One other solution I've thought of was traveling trough the scene graph as normal and adding items to 3 separate lists, separating geometry, shadow casters and lights, and then iterating these lists to draw the correct stuff, is this better, and is it wise to repopulate 3 lists every frame?

• DevDays ‘00 The Netherlands day #2

  - by erwin21

  Day 2 of DevDays 2010 and again 5 interesting sessions at the World Forum in The Hague. The first session of the today in the big world forum theater was from Scott Hanselman, he gives a lap around .NET 4.0. In his way of presenting he talked about all kind of new features of .NET 4.0 like MEF, threading, parallel processing, changes and additions to the CLR and DLR, WPF and all new language features of .NET 4.0. After a small break it was ready for session 2 from Scott Allen about Tips, Tricks and Optimizations of LINQ. He talked about lazy and deferred executions, the difference between IQueryable and IEnumerable and the two flavors of LINQ syntax. The lunch was again very good prepared and delicious, but after that it was time for session 3 Web Vulnerabilities and Exploits from Alex Thissen. This was no normal session but more like a workshop, we decided what kind of subjects we discussed, the subjects where OWASP, XSS and other injections, validation, encoding. He gave some handy tips and tricks how to prevent such attacks. Session 4 was about the new features of C# 4.0 from Alex van Beek. He talked about Optional- en Named Parameters, Generic Co- en Contra Variance, Dynamic keyword and COM Interop features. He showed how to use them but also when not to use them. The last session of today and also the last session of DevDays 2010 was about WCF Best Practices from Gerben van Loon. He talked about 7 best practices that you must know when you are going to use WCF. With some quick demos he showed the problem and the solution for some common issues. It where two interesting days and next year i sure will be attending again.

• Using SharePoint PeoplePicker control in custom ASP.NET pages

  - by Jignesh Gangajaliya

  I was developing custom ASP.NET page for a SharePoint project, and the page uses SharePoint PeoplePicker control. I needed to manipulate the control on the client side based on the user inputs. PeoplePicker Picker is a complex control and the difficult bit is that it contains many controls on the page (use the page source viewer to see the HTML tags generated). So getting into the right bit is tricky and also the default JavaScript functions like, control.disabled; control.focus(); will not work with PeoplePicker control. After some trial and error I came up with the solution to manipulate the control using JavaScript.  Here I am posting the JavaScript code snippet to enable/disable the PeoplePicker Control: function ToggleDisabledPeoplePicker(element, isDisabled) {     try     {         element.disabled = isDisabled;     }            catch(exception)     {}            if ((element.childNodes) && (element.childNodes.length > 0))     {         for (var index = 0; index < element.childNodes.length; index++)         {             ToggleDisabledPeoplePicker(element.childNodes[index], isDisabled);         }     } } // to disable the control ToggleDisabledPeoplePicker(document.getElementById("<%=txtMRA.ClientID%>"), true); The script shown below can be used to set focus back to the PeoplePicker control from custom JavaScript validation function: var found = false;         function SetFocusToPeoplePicker(element) {     try     {         if (element.id.lastIndexOf("upLevelDiv") !=-1)         {             element.focus();             found = true;             return;         }     }             catch(exception)     {}             if ((element.childNodes) && (element.childNodes.length > 0))     {         for (var index = 0; index < element.childNodes.length; index++)         {             if (found)             {                 found = false;                 break;             }                      SetFocusToPeoplePicker(element.childNodes[index]);         }     } } - Jignesh

• Ubuntu 11.10 - How can i stop self-feedback-loop, coming directly from my microphone to speaker?

  - by YumYumYum

  I have microphone audio, which comes instantly to my speaker. I am using default pulseaudio and alsa from the package. I have tried to setup: 1) PA /etc/pulse/default.pa /etc/asound.conf $ ls analog-input-aux.conf analog-input-fm.conf analog-input-mic.conf analog-input-tvtuner.conf analog-output-desktop-speaker.conf analog-output-mono.conf analog-input.conf analog-input-front-mic.conf analog-input-mic.conf.common analog-input-video.conf analog-output-headphones-2.conf analog-output-speaker.conf analog-input.conf.common analog-input-internal-mic.conf analog-input-mic-line.conf analog-output.conf analog-output-headphones.conf iec958-stereo-output.conf analog-input-dock-mic.conf analog-input-linein.conf analog-input-rear-mic.conf analog-output.conf.common analog-output-lfe-on-mono.conf 2) ALSA in lsmod to make sure no loopback modules are loaded etc but none is resolving it. And there are many less information available on this. Has anyone similar problem solution in Ubuntu 11.10? (this problem i have resolved in Ubuntu 11.04 by replacing the default pulseaudio version to latest source from git, but while trying the same in Ubuntu 11.10 does not worked). Any tips please?

• SQL SERVER – Reset SA Password – SQL in Sixty Seconds #066

  - by Pinal Dave

  It has been quite a long time since I posted SQL in Sixty Seconds Video. Here we are back with the new video. One of the most popular question, I often receive is very similar to following: “How do I reset the password for SA username?” “I have forgotten the SA password, what should I do?” “Our DBA just left the job and now noone knows how to reset the SA password. Please help.” Solution Honestly, it is pretty simple to reset the password for SA username. You just have to login to the system where your SQL Server is installed. Open SQL Server Management Studio and login with the help of Windows Authentication. As local system is the admin of the SQL Server, you will get access with administration privileges. Now, open the database, expand Security >> Login folder and right click over SA username. Now, it will bring up the screen where you can change the password for SA. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password. You can read it over here:  SQL SERVER – Forgot the Password of Username SA Change Password of SA Login Using Management Studio You can subscribe to my YouTube Channel for frequent updates.

• Removing port forwardings programmatically on a ControlMaster SSH session

  - by aef

  Quite a while ago I got an answer telling me how to add a port-forwarding on a running SSH ControlMaster process. To know that helps a lot, but I'm still missing a way to remove such a port forwarding after I don't need that anymore. As far as I know, you can do that through the internal command key sequence on normal connections, this seems to be disabled for ControlMaster clients. Even if that would be possible I would need a solution which I can automatize with scripts, which is surely not so easy this way. Is there a way to do it? And is it easily automatizable?

• Is there a way to copy the file paths of ALL active windows' opened files?

  - by frenchglen

  The context of this question, is here. I actually know the answer to my question is yes - like I say in my context, this program can do it (somehow). So the really question is, how can I do it. What code do I put in a simple batch file? (or do I have to compile a tiny c++ exe? and run that exe in the batch file?) Might this code be a solution? (.....EnumDesktopWindows?) To clarify, I know that there's e.g. NirSoft OpenedFilesView which shows allll the technically-opened files in Windows, but it's just the 'visible' user-opened ones that I'm after (whatever you can see in Task Manager's Applications tab). Thanks.

• Organizing an entity system with external component managers?

  - by Gustav

  I'm designing a game engine for a top-down multiplayer 2D shooter game, which I want to be reasonably reuseable for other top-down shooter games. At the moment I'm thinking about how something like an entity system in it should be designed. First I thought about this: I have a class called EntityManager. It should implement a method called Update and another one called Draw. The reason for me separating Logic and Rendering is because then I can omit the Draw method if running a standalone server. EntityManager owns a list of objects of type BaseEntity. Each entity owns a list of components such as EntityModel (the drawable representation of an entity), EntityNetworkInterface, and EntityPhysicalBody. EntityManager also owns a list of component managers like EntityRenderManager, EntityNetworkManager and EntityPhysicsManager. Each component manager keeps references to the entity components. There are various reasons for moving this code out of the entity's own class and do it collectively instead. For example, I'm using an external physics library, Box2D, for the game. In Box2D, you first add the bodies and shapes to a world (owned by the EntityPhysicsManager in this case) and add collision callbacks (which would be dispatched to the entity object itself in my system). Then you run a function which simulates everything in the system. I find it hard to find a better solution to do this than doing it in an external component manager like this. Entity creation is done like this: EntityManager implements the method RegisterEntity(entityClass, factory) which registers how to create an entity if that class. It also implements the method CreateEntity(entityClass) which would return an object of type BaseEntity. Well now comes my problem: How would the reference to a component be registered to the component managers? I have no idea how I would reference the component managers from a factory/closure.

• How to change the fonts used in Foxit Reader?

  - by user982438

  I really want to use Foxit Reader as my default PDF reader for its Tab Interface, and low memory footprint. Having tried mutiple times over the years the only thing that is stopping me are the Fonts. PDF in Adobe Reader looks Regular, but PDF Rendered in Foxit Looks Ugly. Would this solution works in Chrome as well? Since i record Chrome is using Foxit Reader as its embedded PDF engine. And is there any reasons why Fonts are used differently in Adobe and Foxit Reader?

• Unleash AutoVue on Your Unmanaged Data

  - by [email protected]

  Over the years, I've spoken to hundreds of customers who use AutoVue to collaborate on their "managed" data stored in content management systems, product lifecycle management systems, etc. via our many integrations. Through these conversations I've also learned a harsh reality - we will never fully move away from unmanaged data (desktops, file servers, emails, etc). If you use AutoVue today you already know that even if your primary use is viewing content stored in a content management system, you can still open files stored locally on your computer. But did you know that AutoVue actually has - built-in - a great solution for viewing, printing and redlining your data stored on file servers? Using the 'Server protocol' you can point AutoVue directly to a top-level location on any networked file server and provide your users with a link or shortcut to access an interface similar to the sample page shown below. Many customers link to pages just like this one from their internal company intranets. Through this webpage, users can easily search and browse through file server data with a 'click-and-view' interface to find the specific image, document, drawing or model they're looking for. Any markups created on a document will be accessible to everyone else viewing that document and of course real-time collaboration is supported as well. Customers on maintenance can consult the AutoVue Admin guide or My Oracle Support Doc ID 753018.1 for an introduction to the server protocol. Contact your local AutoVue Solutions Consultant for help setting up the sample shown above.

• Good experiences with bulk rate SMS providers?

  - by jen_h

  We're a pretty popular service, our users are currently sending 100000+ SMS messages (projected 180k this month, and continuing to grow) per month. We're currently using a primary domestic provider that doesn't provide bulk rates and doesn't provide short code access. We're using a few backup providers as well for max redundancy, but aren't thrilled by 'em. We're ideally looking for a service that provides good bulk rates/incentives, good uptime/redundancy/reputation, easy API-integration (including respectable error codes!) ;). Right now, we're looking primarily for a domestic US SMS solution, but aren't averse to using the same provider for both International & US. For those of you using bulk SMS right now - what are your recommendations, experiences, etc. in the bulk SMS domain? It sounds like I'm looking for a golden unicorn here, I know, but any data/recommendations/warnings you've got are helpful!

• Is it Secure to Grant Apachie User Ownership of Directories & Files for Wordpress

  - by Oudin

  I'm currently setting up WordPress on an Ubuntu server 12 everything runs fine but there is an issue when it comes to automatically updating and uploading media via WP as Apache "www-data" user does not have permissions to write to the directories. "user1" has full permission All my directories have permissions of 0755 and files 644 my directories setup is as follows: /home/user1/public_html All WP files and directories are in "public_html" In order to work around the auto updating and uploading media I've granted Apache user ownership to the following directories sudo chown www-data:www-data wp-content -R sudo chown www-data:www-data wp-includes -R sudo chown www-data:www-data wp-admin -R I would like to know security wise how secure this is and if it is not secure what would be the best solution? That will allow me to keep all files and directories owned by user1 and still allow wp to be able to automatically update and uploading media

• The fastest way to encode image+audio for Youtube from command line?

  - by Pavel Vlasov

  I have an mp3 and image and I want to make a simple clip to upload onto Youtube. Is there a fast solution? If video formats are so bad designed, then maybe it is possible to use a prerendered video-only clip? This works good except it takes as much time as the audio lasts: ffmpeg -loop_input -r ntsc -i "%IMAGE%" -i "%AUDIO%" -r 1 -acodec copy -shortest -re -force_fps "%VIDEO%" This takes a second but results in a black screen video that is successfully played by a desktop video player but not acceptable by Youtube: ffmpeg -i "%IMAGE%" -i "%AUDIO%" -acodec copy "%VIDEO%" Windows 7. Preserving audio quality is preferred over video quality.

• When Citrix desktop disconnects SAP Client holds session and can't log back in

  - by Stradas

  We have a fairly large Citrix implementation and have just pushed out SAP desktop client to all of the desktops. Everything else is working fine except the following problem: If a user Disconnects their session and the session is running the SAP client, (logging off works fine) the user can not reconnect and log back in. We have a script on the server that terminates the session as a work around. We can see on the server that it is the SAP client that is holding on and running. This is at a large office, but the SAP servers are in another hemisphere. As is the custom Citrix says its SAP and SAP says it is Citrix. I don't like using a powershell script as a substitute for a system configuration solution.

• Using an old PC case and power supply as a HDD Enclosure?

  - by mexiq

  I have 5 HDD and my computer is not handling the situation very well. hehe There are some towers that I can buy to put 4 of my drives out, but I'm thinking that I could use the power source of a failed computer I have and use it to power the 4 (or at least 3) of the drives. The data cables (SATA) will remain connected to the working computer (so no USB solution). The problem is that the power source will not work unless it is connected to the failing computer motherboard. Is there any way I could use the power source without plunging it to the old motherboard? Any "HOW-TO" links may be useful as well.

• Change YYYY-MM-DD to YYYYMMDD everywhere in file

  - by richardh

  I can't just delete all of the hyphens, because elsewhere they are used as minus signs. I can find these dates with [0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\} but I can't figure out how to keep those three different digit wildcards in memory. My attempts end up replacing the dates with the search string (e.g., :%s/[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}/[0-9]\{4\}[0-9]\{2\}[0-9]\{2\}/g). Any ideas? If there's a command line solution, I'd love to learn that, too. Thanks!

• Monitor RAM usage on CentOS and restart Apache at a certain usage

  - by Chris

  Hi, I'm running a CentOS 5.3 server with a basic LAMP stack. I've optimized LAMP and my code to run efficiently as possible, but Apache has a memory leak somewhere that kills my server every hour or so. What is the best way to write a script that will monitor the memory usage and if it peaks over, say, 450MB kill all the Apache processes and restart Apache. I know C++/PHP and basic Linux server administration but I'm not familiar with Perl or bash scripting. I'd be open to learn any solutions, though, as a temporary solution while I find the issue.

• Fibonacci numbers in F#

  - by BobPalmer

  As you may have gathered from some of my previous posts, I've been spending some quality time at Project Euler.  Normally I do my solutions in C#, but since I have also started learning F#, it only made sense to switch over to F# to get my math coding fix. This week's post is just a small snippet - spefically, a simple function to return a fibonacci number given it's place in the sequence.  One popular example uses recursion: let rec fib n = if n < 2 then 1 else fib (n-2) + fib(n-1) While this is certainly elegant, the recursion is absolutely brutal on performance.  So I decided to spend a little time, and find an option that achieved the same functionality, but used a recursive function.  And since this is F#, I wanted to make sure I did it without the use of any mutable variables. Here's the solution I came up with: let rec fib n1 n2 c =    if c = 1 then        n2    else        fib n2 (n1+n2) (c-1);;let GetFib num =    (fib 1 1 num);;printfn "%A" (GetFib 1000);; Essentially, this function works through the sequence moving forward, passing the two most recent numbers and a counter to the recursive calls until it has achieved the desired number of iterations.  At that point, it returns the latest fibonacci number. Enjoy!
