• (Windows Installer) What are some causes for different versions of a program showing 2 entries in ad

  - by Davy8

  Somehow we ended up with something going wrong with one of our recently deployed upgrades (internal deploy, only about a dozen machines or so) and there are now 2 entries for our program showing up in windows add/remove program and I'm trying to figure out what could have caused this. In a nutshell what does windows use to determine whether a program is replacing a previous version or if it's a new program? We are using WiX to create our installers, but nothing in the SVN revisions shows much out of the ordinary (been working fine for the past year with over 100 upgrades). Product version is * because we're forcing a major upgrade each time, but the upgrade code has never changed.

• Best .Net/C# book for an interview

  - by DrunkenBeard

  Hi, I'm having an interview for an internship in the coming days and would like to know if there are any books that are particulary suited for preparing interviews. The interview is not particulary hard, just some questions about .Net and C# plus an algorithm to code. I tried C# in a Nutshell but it goes in too much detail for what I want to achieve. I'm more looking for a good yet small book that explains the important concepts of the .Net framework and C#, I already know the details, just want formal explanations so I'm confident when answering. Thanks :)

• Tkinter mouse event initially triggered

  - by user3714884

  I'm currently learning Tkinter and I cannot find a solution for my problem here nor outside Stackoverflow. In a nutshell, all events that I bind to my widgets are triggered initialy and don't respond to my actions. In this example, the red rectangle appears on the canvas when I run the code, and color=random.choice(['red', 'blue']) revealed that the event binding doesn't work after that: import Tkinter as tk class application(tk.Frame): def __init__(self, master=None): tk.Frame.__init__(self, master) self.can = tk.Canvas(master, width=200, height=200) self.can.bind('<Button-2>', self.draw()) self.can.grid() def draw(self): self.can.create_rectangle(50, 50, 100, 100, fill='red') app = application() app.mainloop() I use a Mac platform, but I haven't got a clue about its role in the problem. Could anyone please point me at the mistake i did here?

• No exit option if something is running

  - by max

  How can I catch something going on if the user chooses the exit option from a menu? I mean I'd like to be able to manage the event of a user who is going to close the application but some activity is being performed so he/she shouldn't be able to exit. Here's the code I wrote. In a nutshell : recording is being performed -- user clicks exit -- WARNING "Process is running you can't do it"(The process goes on) nothing is running -- user clicks exit -- application closes Is it possible to solve the problem by just adding a few lines of code without having to rewrite the entire program? thanks very much in advance. MAX exitAction = new AbstractAction("Exit") { public void actionPerformed(ActionEvent e) { System.exit(0); } }; exitAction.putValue(Action.NAME, "Exit"); // description exitAction.putValue(Action.SHORT_DESCRIPTION, "Exit application");

• Prevent Cookies From Being Sent on AJAX Request

  - by user340571

  Hello everyone, I have a web service that I invoke from script but that does not need any information stored in cookies. Anytime I make a request to the service, the cookie is sent along with it. I understand that by default cookies are sent with HTTP request, but is there any way at all to overwrite that behavior and not send the cookie? In a nutshell, I am issuing my request like this: $.ajax({ type: "POST", cache: false, url: url, data: data, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { successFunc(response); }, error: function(xhr) { errorFunc(xhr); } });

• How can I find days between different paired rows?

  - by Anthony

  I've been racking my brain about how to do this in one query without PHP code. In a nutshell, I have a table that records email activity. For the sake of this example, here is the data: recipient_id activity date 1 delivered 2011-08-30 1 open 2011-08-31 2 delivered 2011-08-30 3 delivered 2011-08-24 3 open 2011-08-30 3 open 2011-08-31 The goal: I want to display to users a single number that tells how many recipients open their email within 24 hours. E.G. "Users that open their email within 24 hours: 13 Readers" In the case of the sample data, above, the value would be "1". (Recipient one was delivered an email and opened it the next day. Recipient 2 never opened it and recipient 3 waited 5 days.) Can anyone think of a way to express the goal in a single query? Reminder: In order to count, the person must have a 'delivered' tag and at least one 'open' tag. Each 'open' tag only counts once per recipient.

• Java: Get current Date and Time from Server not System clock

  - by Insectatorious

  In my Java program, I need to create an instance of the current moment in time. I use Date date = new Date(); This gives me the current date and time as per the host machine's system clock. Is there any way I can get the current date and time from an online server? The world time server perhaps? I have seen this post and it describes what I want but I'm afraid I need more help than what's provided there. In a nutshell, I want to get a date and time that is not dependant on the host machine's system clock. Thanks!

• SQL SERVER – Developer Training Kit for SQL Server 2012

  - by pinaldave

  Developer Training Kit is my favorite part of any product. The reason behind is very simple because it give the single resource which gives complete overview of the product in nutshell. A developer can learn from many places – books, webcasts, tutorials, blogs, etc. However, I have found that developer training kits are the best starting point for any product. Start with them first, see what are the new features as well what is the new message a product is coming up with. Once it is learned the very next step should be to identify the right learning material to explore the preferred topic. The SQL Server 2012 Developer Training Kit includes technical content including labs, demos and presentations designed to help you learn how to develop SQL Server 2012 database and BI solutions. New and updated content will be released periodically and can be downloaded on-demand using the Web Installer. Download SQL Server 2012 Developer Training Kit Web Installer. This training kit was available earlier this year but it is never late to explore it if you have not referred it earlier. Additionally, if you do not want to download complete kit all together I suggest you refer to Wiki here. This wiki contains all the same presentations and demo notes which web installer contains. Refer to SQL Server 2012 Developer Training Kit Wiki Wiki contains following module and details about Hands On Labs Module 1: Introduction to SQL Server 2012 Module 2: Introduction to SQL Server 2012 AlwaysOn Module 3: Exploring and Managing SQL Server 2012 Database Engine Improvements Module 4: SQL Server 2012 Database Server Programmability Module 5: SQL Server 2012 Application Development Module 6: SQL Server 2012 Enterprise Information Management Module 7: SQL Server 2012 Business Intelligence Hands-On Labs: SQL Server 2012 Database Engine Hands-On Labs: Visual Studio 2010 and .NET 4.0 Hands-On Labs: SQL Server 2012 Enterprise Information Management Hands-On Labs: SQL Server 2012 Business Intelligence Hands-On LabsHands-On Labs: Windows Azure and SQL Azure As I said, if you have not downloaded this so far, it is never late to explore it. Trust me you will atleast learn one thing if you just explore the content.

• Integrating Twitter Into An ASP.NET Website Using OAuth

  Earlier this year I wrote an article about Twitterizer, an open-source .NET library that can be used to integrate your application with Twitter. Using Twitterizer you can allow your visitors to post tweets, view their timeline, and much more, all without leaving your website. The original article, Integrating Twitter Into An ASP.NET Website, showed how to post tweets and view a timeline to a particular Twitter account using Twitterizer 1.0. To post a tweet to a specific account, Twitterizer 1.0 uses basic authentication. Basic authentication is a very simple authentication scheme. For an application to post a tweet to JohnDoe's Twitter account, it would submit JohnDoe's username and password (along with the tweet text) to Twitter's servers. Basic authentication, while easy to implement, is not an ideal authentication scheme as it requires that the integrating application know the username(s) and password(s) of the accounts that it is connected to. Consequently, a user must share her password in order to connect her Twitter account with the application. Such password sharing is not only insecure, but it can also cause difficulties down the line if the user changes her password or decides that she no longer wants to connect her account to certain applications (but wants to remain connected to others). To remedy these issues, Twitter introduced support for OAuth, which is a simple, secure protocol for granting API access. In a nutshell, OAuth allows a user to connect an application to their Twitter account without having to share their password. Instead, the user is sent to Twitter's website where they confirm whether they want to connect to the application. Upon confirmation, Twitter generates an token that is then sent back to the application. The application then submits this token when integrating with the user's account. The token serves as proof that the user has allowed this application access to their account. (Twitter users can view what application's they're connected to and may revoke these tokens on an application-by-application basis.) In late 2009, Twitter announced that it was ending its support for basic authentication in June 2010. As a result, the code examined in Integrating Twitter Into An ASP.NET Website, which uses basic authentication, will no longer work once the cut off date is reached. The good news is that the Twitterizer version 2.0 supports OAuth. This article examines how to use Twitterizer 2.0 and OAuth from a website. Specifically, we'll see how to retrieve and display a user's latest tweets and how to post a tweet from an ASP.NET page. Read on to learn more! Read More >

• Telesharp – An Application Repository for .NET applications

  - by cibrax

  A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

• Let&rsquo;s keep informed with &ldquo;Data Explorer&rdquo;

  - by Luca Zavarella

  At Pass Summit 2011 a new project was announced. It’s a Microsoft SQL Azure Lab and its codename is Microsoft “Data Explorer”. According to the official blog (http://blogs.msdn.com/b/dataexplorer/), this new tool provides an innovative way to acquire new knowledge from the data that interest you. In a nutshell, Data Explorer allows you to combine data from multiple sources, to publish and share the result. In addition, you can generate data streams in the RESTful open format (Open Data Protocol), and they can then be used by other applications. Nonetheless we can still use Excel or PowerPivot to analyze the results. Sources can be varied: Excel spreadsheets, text files, databases, Windows Azure Marketplace, etc.. For those who are not familiar with this resource, I strongly suggest you to keep an eye on the data services available to the Marketplace: https://datamarket.azure.com/browse/Data To tell the truth, as I read the above blog post, I was tempted to think of the Data Explorer as a "SSIS on Azure" addressed to the Power User. In fact, reading the response from Tim Mallalieu (Group Program Manager of Data Explorer) to the comment made to his post, I had a positive response to my first impression: “…we originally thinking of ourselves as Self-Service ETL. As we talked to more folks and started partnering with other teams we realized that would be an area that we can add value but that there were more opportunities emerging.” The typical operations of the ETL phase ( processing and organization of data in different formats) can be obtained thanks to Data Explorer Mashup. This is an image of the tool: The flexibility in the manipulation of information is given by Data Explorer Formula Language. This is a formula-based Excel-style specific language: Anyone wishing to know more can check the project page in addition to aforementioned blog: http://www.microsoft.com/en-us/sqlazurelabs/labs/dataexplorer.aspx In light of this new project, there is no doubt about the intention of Microsoft to get closer and closer to the Power User, providing him flexible and very easy to use tools for data analysis. The prime example of this is PowerPivot. The question that remains is always the same: having in a company more Power User will implicitly mean having different data models representing the same reality. But this would inevitably lead to anarchical data management... What do you think about that?

• Clustering/load balancing for cluster unaware applications

  - by AaronLS

  Forgive me if I use any of these terms incorrectly. I am wondering if there is any kind of software that would allow my two "join" two computers together such that a cluster unaware application could utilize their combined computing resources? By "cluster unaware" I mean an application that isn't designed to share work across multiple services. My understanding is that clustering is enabled by the specific application by it's architecture, such that messaging with multiple instances of the application coordinate the sharing of work. Instead I am looking for something that enables clustering at the OS or virtualization level, so that any application could essentially be clustered. Failing that, I am also wondering about the following scenario: We have 3 different applications we will call A, B, and C. We have 2 single core computers. At any given time lets say that any combination of those applications will be CPU intensive. In cases where only 2 of those apps are very active, have one of them moved over to a different server. In a nutshell, some sort of dynamic automatic shuffling of the application's load. I have heard of virtual machines that can be migrated across physical machines while live, but I am wondering if this can be done automatically in response to an application's or VM's CPU activity?

• Ubuntu server or Debian server (to run C++ apps developed on Ubuntu)

  - by skyeagle

  I have written a number of C++ server side daemons for my website, using my Ubuntu 9.10 dev machine. The C++ apps I mentioned above are "GUI-less" daemons (and libraries used by the daemons). I am now about to host my website and need to decide whether to go with Debian server or Ubuntu server. In a nutshell, here is the situation: I developed on Ubuntu desktop because I preferred the more friendly GUI I would like to deploy on Debian Server because of the (perceived?) robustness of the Debian server over Ubuntu server (I may be totally wrong here - and in fact, this is really what this question is all about) If Debian server is indeed more robust than Ubuntu server, then I have no choice but to go with Debian server - BUT, will my Ubuntu developed C++ apps run on the server? (or do I need to recompile them on the server? (I'd HATE to have to do this, because I want to keep the server machine clean and light - no GUI, no dev tools etc). This last question is really about binary compatability between Ubuntu and Debian. I want the server to be robust, secure and stable, and simply act as a server (i.e. LAMP and very little else - no GUI etc). Given that requirement, and the fact that I need to run my C++ apps (developed on Ubuntu 9.10), I need advice on which OS to choose for the server. Ideally, any advice will be backed with a reason. I am particularly interested in hearing from people who have been in an identical situation, or done something similar.

• How to move my data from my old MacBook Pro to my new one?

  - by Tim Büthe

  I just purchased a new MacBook Pro and already got an 2008 model. I wonder how I move all my data over to the new one. My first idea was, to use my Time Machine backup and restore from it, which seems to be a good idea and should work just fine regarding to this link: http://blog.duncandavidson.com/2008/01/restoring-from-time-machine.html. But, since my current MacBook got older Software on it, like iLife '08 instead of iLife '09 I would have to upgrade this afterwards. Is this correct, or does Time Machine does some magic to exclude well known software? And is it possible to reinstall or upgrade iLife with the included installation DVDs? My second idea is, to just swap the hard drives instead of using the Time machine backup. If it is not too complicated to remove the hdd, this should be the fastest way. This also has the benefit, that the 2008er MacBook then contains a brand new installation and I don't have to remove all my stuff or reinstall Mac OS before I give it away. My question on that second idea would be: does snow leopard handle this stuff correctly? I reboot with the new hardware and all just works fine? So in a nutshell: What would you do: restore from backup or swap drives? And what about the new software?

• Change Windows Authentication user for Sql Server Management Studio

  - by Asmor

  We're using Sql Server 2005 with Windows Authentication setup. So normally, when you log in using e.g. Sql Server Management Studio, it forces you to log in at MACHINE_NAME\Username. Anyways, on this one particular computer, the person said they had to make a new account called User01 to do something and showed me where she'd created it under security in the "master" system database. And so now when she logs in, it's listed as MACHINE_NAME\User01 (not the actual Windows user name). It's still set to Windows Authentication, though, and I'm unable to change the login name. Now here's where the real problem comes in... I didn't realize that she was being logged in under this user name at the time, and I disabled it to see what would happen. Now I can't log into the server under her account. I created a new account in Windows called test, and as expected SSMS had the username as MACHINE_NAME\test, and I was able to log in fine. However, the area where the User01 account was listed is not visible to me as far as I can tell and so I can't reenable it. I also tried running the following query: alter login User01 ENABLE And got this error: Msg 15151, Level 16, State 1, Line 1 Cannot alter the login 'User01', because it does not exist or you do not have permission. So in a nutshell, ideally I'd like to reenable User01 somehow, just to get things back to where they used to be. Failing that, how can I force SSMS to log in using the Windows account name as it should be, rather than trying to use User01?

• Pair programming with tmux and Vagrant

  - by neezer

  Does anyone have a clear step-by-step guide for setting up a shared tmux session on a Vagrant vbox that my coworkers (on our local office lan) could SSH into? The articles I've found online only seem to cover setting this up from machine to machine (no virtualbox setups), and I'm not very good at networking, so I haven't been able to extrapolate a solution... We're all running the latest Macs in our office, btw. Here's one article I've found but haven't been able to get working with Vagrant: http://blog.voxdolo.me/remote-pairing-with-vim-and-tmux.html EDIT: To clarify, I don't really know how I should be setting up Vagrant to allow me to SSH into it from a machine outside the one hosting the VM. The article above suggests that I add the tunnels host on my physical machine running the VM (here-on referred to as the MBP), so I did that. Next is the ProxyCommand host declaration, which I have also assumed should live on the MBP. So next I try SSHing into the MBP from a guest machine (another separate physical machine on my network), and that seems to work... but that only gets me into the MBP, not the Vagrant image running on the MBP. I normally login Vagrant image on the MBP via vagrant ssh (per the docs), and I know how to forward ports on the Vagrant VM to the MBP, but it's unclear to me how I could forward ports/SSH from the MBP to the Vagrant VM, which I assume I would need to do so that my guest machine could SSH in--through the MBP--to my Vagrant image. That, in a nutshell, is what I'm trying to accomplish. I do my development work in Vagrant VMs which keeps my MBP nice and clean of any dev-related cruft and also keeps my dev environments totally isolated from one another, yet I would like to start pair-programming with my coworkers via tmux, thus the reason why I've asked this question. I would like to accomplish all of this without setting up an additional user account on the MBP, or giving my coworkers access to my local user account on the MBP to get to my Vagrant VM, if that's at all possible.

• How to limit SMTP delivery to hourly batches

  - by Jeremy W

  Moved over from StackOverflow. Sorry if you saw it there first In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want. In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so. Mail is being sent via ASP.Net. Also, I wouldn't be sending 1 million a day. Probably 30,000 tops - and doing that only a few times a month. I'm just trying to avoid a tidal wave of 30k going out in 1 minute and setting off every network spam monitoring alarm in North America. I know I could do it with a combination console app / scheduled job. My question was if there was an easier way to accomplish this with the Virtual SMTP Server settings on Win2k3 Is this possible?

• Mod_rewrite to eliminate query strings

  - by Greg Frommer

  Hi everyone, I have been working on this for a while but I'm not finding exactly what I am looking for. I am writing a webapp to let my users create and publish pieces of HTML content in a domain and URL folder structure of their choosing. All of the content and requested URL structures are stored in a database. I have all of the code in my index.php (in the root folder) to access the database content, and based on the server name (and hopefully folder structure) will pick out the proper content from the DB and display it to the end-users browser. So my situation looks like this: www.test.com/index.php?id=123234345 ... will display the proper page, but I want my users to be able to define a unique "page name" instead of using the numeric index (also I want to hide the /index.php part) so what I would like the end-user to see is: www.test.com/arbitrary-unique-keyword/keyword2/keyword3 which will invoke the index.php page in the root folder. Then I will use the PHP $_SERVER['PATH_INFO'] variable to match the requested folder structure up with the proper content in my database and display that. All the material I have found so far expects me to hard code parts of the folder structure into the rules.... but I think I want something simpler (perhaps). So the question in a nutshell: How do I use mod_rewrite to allow all "non-existent" folder paths be passed through to a main index.php residing in the root folder? (For all paths that DO exist, like for calls to images... I want those to succeed and not be directed to the index.php obviously) Thanks everyone, please let me know if I can clear anything up.

• Change default profile directory per group

  - by Joel Coel

  Is it possible to force windows to create profiles for members of one active directory group in a different folder from members in another active directory group? The school here uses DeepFreeze to protect public computers. In a nutshell, DeepFreeze prevents all changes to a hard drive such that every time you restart the machine the disk is identical to it was at the time you froze it. This is a bit different than restoring to an image, in that it never really wrote changes to disk in a permanent way in the first place. This has a few advantages over images: faster recover times, and it's easy to thaw the machine for a few minutes to perform maintenance such as windows updates (which can even be automated). DeepFreeze also allows you to configure a "thawspace" partition, where changes are persistent across reboots. One of the weaknesses of DeepFreeze is that you end up needing to create a new profile every time you log in, unless your profile existed at the time the machine was frozen. And even then, any changes you make to your profile while working on a frozen machine are lost. As students have frequent legitimate needs to log in to our classroom machines, there is currently a lot of cleanup involved from time to time in removing their old profiles and changes, so I want to extend DeepFreeze to protect our classroom computers as well as public computers. The problem is that faculty have a real need to keep a stateful profile locally on these classroom computers. The solution I would like to use is to configure Windows via group policy (or even manually, if that's the way I'll have to do it) to place profile folders on the thawspace partition, but only for members of the faculty security group. Is this possible?

• Looking for suggestions for hosting Windows 2000 Server in the cloud / VPS / etc?

  I have a Windows 2000 Server, currently virtualized in Hyper-V, that I would like to get running off-site as a backup (cloud, VPS, etc). You can't virtualize in EC2 and I'm fairly certain there are no Server 2000 AMI's floating about (correct me if I'm wrong!). If anyone has a recommendation on how I can get a virtualized Windows 2000 Server running in a secure, remote environment I would be grateful. As far as locations go I'd be interested in both North America as well as Australia and Europe. In a nutshell, we're ploughing our way out of a legacy codebase and this server is the last that remains of the legacy apps. However, it is still very much used by our clients. Everything is backed up each night (data, images, etc) to tape which is then taken offsite. However, in the event of a fire I would love to have a backup legacy server to point DNS records to. So while I am rebuilding from the ashes our services would already be available. It would save a lot of time and make my managers all the more happy (and that's what it's all about, riighhtt? :D) Thank you all for your suggestions. Please let me know if I've left out any important information. Additional info: - the legacy codebase does not function properly in Server 2003

• 100% uptime for a web application

  - by Chris Lively

  We received an interesting "requirement" from a client today. They want 100% uptime with off-site failover on a web application. From our web application's viewpoint, this isn't an issue. It was designed to be able to scale out across multiple database servers, etc. However, from a networking issue I just can't seem to figure out how to make it work. In a nutshell, the application will live on servers within the client's network. It is accessed by both internal and external people. They want us to maintain an off-site copy of the system that in the event of a serious failure at their premises would immediately pick up and take over. Now we know there is absolutely no way to resolve it for internal people (carrier pigeon?), but they want the external users to not even notice. Quite frankly, I haven't the foggiest idea of how this might be possible. It seems that if they lose Internet connectivity then we would have to do a DNS change to forward traffic to the external machines... Which, of course, takes time. Ideas? UPDATE I had a discussion with the client today and they clarified on the issue. They stuck by the 100% number, saying the application should stay active even in the event of a flood. However, that requirement only kicks in if we host it for them. They said they would handle the uptime requirement if the application lives entirely on their servers. You can guess my response.

• Wildcard subdomain setup ... want to change host IP throws off client A records... what to do...

  - by Joe

  Here is the current set up (in a nutshell). The site is set up with a wildcard subdomain, so *.website.com is accessible. Clients can then domain map their own domains with an A record to the server IP address and it will translate the to appropriate *.website.com with re directions and env variables in htaccess. Everything is working perfect... but now comes the problem. The site has grown larger than a single DQC Xeon server can handle at peak times. Looking at cloud options seems tempting, but clients are pointing their domains to a single IP address with the A record (our server). Now, this was probably bad planing from the start, but the question is, if this was to be done today, how would we set it up so that clients use a CNAME perhaps to point their domains to our server rather than an A record. And, if that is not possible for the root domain, how can we then use multiple IP addresses on our side to translate the incoming http request? Complex enough? Hope I've explained it well!

• CentOS: AJAX/jQuery not working

  - by Australiya

  In a nutshell, I have an unmanaged VPS. At one time, it had Ubuntu 10.10 server on it, then I reinstalled it with CentOS 6 and updated it to CentOS 6.2. Now, the problem is, the AJAX/jQuery shoutbox has ceased working (I assume it uses one of the two to inject itself into a div and then refresh when new messages are posted, I'm not sure, I didn't write these), and the plug-board script now shows me a lime green blank page. No changes to the source codes have been made, and they are in the location they expect themselves to be. I have Apache2, MySQL 5, PHP 5, and I did install the php-xml libraries. What am I missing? It's gotta be server side because the scripts themselves are fine, if I move them to a different server they work just fine. I'm not getting any errors related to this in the error_log file. Thanks in advance! Edit: If you want, you can look at the plugboard at kazeshini.net/plugboard and there's an installation of the chatbox at silverlotus.kazeshini.net/yshout/example, I know nothing about scripts and debugging so better someone else looks at it than someone that doesn't know what they're looking for.
