  • How to push changes from Test server to Live server?

    - by anonymous
    As a beginner, I finally noticed the issue with making changes to the live server I've been working on, now that I have a couple users on it, since I bring it down so often. I created an EC2 image of my live server and set up a separate instance on EC2, so now I have 2 EC2 instances, Stage and Production. I set up GitHub and push changes to stage and test my code there, and when it's all done and working, I push it to the production branch, and everything is good. And there is a slight issue here since I name my files config_stage.js and config_production.js and set up .gitignore on each server, and in my code, I would have it read the ENV flags and set up the appropriate configs, is this the correct approach? And my main question is: how do you keep track of non-code changes to the server? For example, I installed HAProxy, Stunnel, Redis, MongoDB and several other things onto the Stage server for testing and now that it's all working and good, how do I deploy them to production? Right now, I'm just keeping track of everything I installed and copying configuration files over, which is very tedious and I'm afraid I may have missed a step somewhere. Is there a better way to port these changes over from my test server to my live server?

  • Migrate olddomain.com to newdomain.com

    - by eHx
    I have 2 domains that are registered at GoDaddy : domaina.com (not hosted, only domain name is registered to GD) domainb.com (hosted at a different webhost, domain name registered to GD) domainb.com is an already working site, with a different webhost, but the domain name is registered to GoDaddy(and I assume the nameservers are changed to redirect to the webhost). Now, I don't understand why this was done, but domainb.com is considered a subdomain on the host... meaning the files are in a seperate folder on the server. Ex : public-html/domainb.com/public-html/FILES The structure is similar to this on the webhost : HostNAME (main root folder) domainb.com (subdomain of hostname) domainc.com (etc...) domaind.com (etc...) I want to transfer the site domainb.com to domaina.com, meaning domaina.com will become the new website, without having to re-upload all the content and CMS. The old one will redirect to domaina.com once the transfer is done (using 301 redirects). Can anyone tell me how I can do this? Thanks !

  • Using the BackgroundWorker in a Silverlight MVVM Application

    - by axshon
    With Silverlight 4 and the Entity Framework you get a lot of work done on your behalf in terms of standard UI CRUD-style operations. Validations and I/O are pretty easy to accommodate out of the box. But sometimes you need to perform some long running tasks either on the client or on the server via service calls. To prevent your UI from hanging and annoying your users, you should consider placing these operations on a background thread. The BackgroundWorker object is the perfect solution for this...(read more)

  • Nginx ssl redirection of images

    - by krishna raj
    Hi. I am trying to set up nginx as reverse proxy for a tomcat server using SSL connection. I want the client's browser to load my tomcat application when nginx reverse proxy's IP is called from client's browser. My tomcat application's address is 192.168.25.25 and nginx proxy's address is 192.168.25.50 In my nginx.conf file i have added these lines # location / { proxy_pass https://192.168.25.25:443/myapp/; proxy_redirect https://192.168.25.25/myapp/ https://192.168.25.25/; } # Some of the images in my application is stored at 192.168.25.25/images/ . Now these directories cant be accessed as the proxy_pass is set to 192.168.25.25:443/myapp. Is there way to access images directory also without changing proxy_pass ? Thanks in advance.

  • Are Ruby on Rails / Grails the fastest frameworks for getting sites up quickly?

    - by Jon
    I'm considering using Grails for a new website, but am open to other/new programming languages and frameworks. I have done development using J2EE/JSF2, ASP.NET, and PHP. Is Grails or Ruby on Rails pretty much the best way to get functionality up and running quickly? Some initial thoughts: DJango looks similar to RoR/Grails and I'd consider it GWT is an interesting concept but it doesn't seem like turnaround time is quite as fast Thanks, -Jon

  • Does it matter to you that a software is "available source" but not "open source"

    - by ccpod
    You probably know the list of open source licenses officially approved by the OSI. Most notably I guess would be the GPL, MIT, [insert your favorite license here]. I recently ran into a project which although was open source (the creator made all source code available), was not officially open source under one of those official licenses. It released the source, but made no promise to release the source in the future. It allowed modification suggestions, but made no promises to accept patches and disallowed external distribution of externally-patched versions. It allowed the use of the software in commercial or paid projects, but disallowed the sale of the software itself. I suppose it could be called "available source" not open source as we like to think of it. I can see why the management team of a company wouldn't want to do business with this software. They can't fork it, they can't sell it, they can't create their own version of the software and distribute it or sell it. But would it matter to you as part of a software engineering team who's just using this software? I can still get my work done with it, I can use it in a project for which I'm paid (but I can't sell the software itself, which I'm not in the business of doing anyway), and I can make changes to the code to make it behave differently for my needs (but I can't make those modifications public), and if I do want those modifications officially made available to others, the approval is up to the project itself and they choose whether to incorporate them in an official release or not. So we know that a company that wants to base its business on this "available source" software can't do that, but as someone from the software engineering team, would those differences matter to you or do they seem less relevant? Curious what others think of this.

  • Which SSL do I need?

    - by Maik Klein
    I need to buy a ssl certificate. Now there are so many different alternatives with a huge price range. I know the very basic differences of browser compatibility and security level. But I need a "cheap" ssl certificate. My homepage looks like this http://www.test.com Now if I go to the loginpage i should switch to https like this https:/www.test.com/login I am also considering to secure the whole site if the user has singed in. Now there are sites which are offering SSl for 7$/year. Would this do the job? Or would you recommend me to get something more expensive like this one? I want to add paypal support in a later version of my website and I don't want to save money on the wrong end. What would you recommend me?

  • ASP.NET Security Exception when Switch IIS7 to Use UNC Path for Content

    - by Jeremy H.
    I have a Windows Server 2008 R2 box running IIS7.5 with Medium Trust configured for ASP.NET. When I have the website running from local content (e.g.: c:\inetpub\wwwroot) everything works fine. When I change IIS to use a UNC path for the content (e.g.: \\computer\wwwroot) I get the following error: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I'm trying to figure out why ASP.NET/IIS would allow for the SQL call when using local content but not when using a UNC path. Any ideas what I need to do to use a UNC path from IIS7 properly?

  • Methodology behind fetching large XML data sets in pieces

    - by Jerry Dodge
    I am working on an HTTP Server in Delphi which simply sends back a custom XML dataset. I am not following any type of standard formatting, such as SOAP. I have the system working seamlessly, except one small flaw: When I have a very large dataset to send back to the client, it might take up to 2 minutes for all the data to be transferred. The HTTP Server I'm building is essentially an XML Data based API around a database, implementing the common business rule - therefore, the requests are specific to the data behind the system. When, for example, I fetch a large set of product data, I would like to break this down and send it back piece by piece. However, a single HTTP request calls for a single response. I can't necessarily keep feeding the client with multiple different XML packets unless the client explicitly requests it. I don't have any session management, but rather an API Key. I know if I had sessions, I could keep-alive a dataset temporarily for a client, and they could request bits and pieces of it. However, without session management, I would have to execute the SQL query multiple times (for each chunk of data), and in the mean-time, if that data changes, the "pages" might get messed up, therefore causing items to show on the wrong pages, after navigating to a different page. So how is this commonly handled? What's the methodology behind breaking down a large XML dataset into chunks to save the load?

  • Screen resolution of Googlebot mobile?

    - by Baumr
    Does Googlebot-Mobile have a viewport resolution it sends across? If so, what is it? It's a general question with broad relevance, but I am asking with reference to responsive design: particularly when serving different image resolution to different viewports via JavaScript. While Googlebot has its issues with JavaScript, it will become better with time. Thus, it would be good to know which version of the same image would be crawled (since most responsive image JS solutions base their logic on resolution). Feature phones Googlebot-Mobile: SAMSUNG-SGH-E250/1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/6.2.3.3.c.1.101 (GUI) MMP/2.0 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html) DoCoMo/2.0 N905i(c100;TB;W24H16) (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html) Smartphone Googlebot-Mobile: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8B117 Safari/6531.22.7 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)

  • Application Lifecycle Management with Visual Studio 2010 – Wrox Book

    - by Guy Harwood
    After running with a somewhat disconnected set of tools (vs 2008, Ontime, sharepoint 2007) for managing our projects we decided to make the move to Team Foundation Server 2010.  With limited coverage of the product available online i went in search of a book and found this… View this book on the Wrox website I must point out that i have only read 10 of the 26 chapters so far, mainly the ones that cover source code control, work item tracking and database projects.  This enables our dev team to get familiar with it before switching project management over at a future date. Needless to say i am very impressed with the detail it provides, answering pretty much every question i had about TFS so far.  I'm looking forward to digging into the sections on testing, code analysis and architecture. Highly recommended.

  • IE Kerberos failure on some machines with CNAME web server (with SPN for host's A record)

    - by Eric Thames
    It's fairly well known that IE doesn't like to do Kerberos against hosts that are registered in DNS as CNAMEs. What happens is that IE turns around and uses the underlying A record for the host for looking up the Service Principal Name (SPN). On a test network we are able to get Kerberos working by having the SPN registered for the A record of the host, so that Kerberos authentication happens successfully when accessing the web server via it's CNAME in the browser. Kerberos authentication works properly when directly accessing the web server with the A record host in the URL, but for various reasons that are beyond my control, it is desired to use the CNAME. On the production network, this same configuration fails though and I can't figure out why. Any thoughts? This is a java web application using the SPNEGO library - not IIS. Kerberos authentication is working properly in both the test and production networks (and has been confirmed to not fail back to NTLM), but the CNAME access only works in test.

  • Visual Database Design Application

    - by tshauck
    Hi, I'm getting to the point where the applications I write need a little more structure during the planning phase. So I'd like to use some sort of visual tool to design the tables and relationships. I'm on a mac and have tried mysql workbench, but I find it buggy and a bit bloated for my intended use. Is something that I could design in that has a nice interface and is primarily a tool for visual design? Thanks

  • Vizioz is back on the web

    - by Vizioz Limited
    I founded Vizioz in 1996 as a website development business. Since then Vizioz has come in and out of focus, it is time to start building Vizioz into a website development consultancy. Over the following two months we will be launching our new website where we will be promoting our ASP.NET, C#, XHTML, CSS, XSLT, SQL, Umbraco Development, Wordpress Development and Graphic Design services, and of course our website will be powered by the open source content management system called Umbraco CMS which we have used for 10+ client sites in the last twelve months.I will be using this new blog to talk about client projects we are currently working on and any Umbraco development related bits of code that we feel would be good to release back to the Umbraco community.
