  • Cooking With Expression: HTML 5 and Expression Web

    - by David Wesst
    I finally got the first one done! This is the first of a series of webcasts that I have wanted to do for a while. I call it Cooking with Expression because developing great user experiences are very similar to cooking great food. So please, check it out, leave some feedback, and enjoy! --- To kick off the series, we want to talk about some techniques that we will be using throughout the series for the different recipes. Since HTML 5 is literally the future of the web and buzz topic in development today, we thought we would start off with that. In this episode we are going to teach you how to use one of your your present day tools Microsoft Expression Web with HTML 5. Cooking with Expression - HTML 5 in Expression Web from David Wesst on Vimeo.

  • Creating a simple RSS reader using ListView,XMLDatasource,DataPager web server controls

    - by nikolaosk
    In my last ASP.Net seminar someone noticed that we did not talk at all about the XmlDataSource,ListView,DataPager web server controls. It is rather impossible to investigate/talk about all issues regarding ASP.Net in a seminar but I promised to write a blog post. I thought that I could combine all those three web server controls to create a RSS reader. 1) Launch Visual Studio 2008/2010. Express editions will work fine. 2) Create an empty asp.net web site. Choose an appropriate name. We will not write...(read more)

  • How does the GPL work in regards to languages like Dart which compile to other languages?

    - by Peter-W
    Google's Dart language is not supported by any Web Browsers other than a special build of Chromium known as Dartium. To use Dart for production code you need to run it through a Dart-JavaScript compiler/translator and then use the outputted JavaScript in your web application. Because JavaScript is an interpreted language everyone who receives the "binary"(Aka, the .js file) has also received the source code. Now, the GNU General Public License v3.0 states that: "The “source code” for a work means the preferred form of the work for making modifications to it." Which would imply that the original Dart code in addition to the JavaScript code must also be provided to the end user. Does this mean that any web applications written in Dart must also provide the original Dart code to all visitors of their website even though a copy of the source code has already been provided in a human readable/writable/modifiable form?

  • How do I encrypt the source code on the webserver?

    - by Ashin k n
    I have a web application developed using Python, HTML, CSS & JavaScript. The customer installs it in any of their own Machine and uses it through their LAN. In short the customer sets up the webserver in any of their own machine. Since its a web application, all the source code is open for the customer in the document root directory of webserver. I want to encrypt the whole source code in the document root directory in such a way that it should not effect the working of the web application. Is there is any way to encrypt the Python, HTML, CSS & JavaScript for this purpose.

  • Looking for reading material on application architecture with web UI

    - by toong
    I'm looking for articles (or other reading material) on the topic of fat client applications with a web UI layer. Open-source projects that use this architecture would be very interesting too. Such an application would embed one (or more) browser-window(s) (chromiumembedded for example). You would need bidirectional communication between your web-UI and your domain model/services. I think this allows quick prototyping the UI, a clean separation between logic and UI and potentially easier portability across platforms (compared to WinForms for example). But that is just my view, I was looking for the view of people who have been on that road. An example of an application using a web-ui layer is Light Table. Unfortunately it is not open source (at this point?).

  • PostSharp deployment to build machine- use Setup installation, not NuGet package.

    - by Michael Freidgeim
    PostSharp has well documented different methods of installation. I've chosen installing NuGet packages, because according to  Deploying PostSharp into a Source Repository NuGet is the easiest way to add PostSharp to a project without installing the product on every machine. However it didn't work well for me. I've added PostSharp NuGet package to one project in the solution.  When I wanted to use PostSharp in other project, Visual Studio tab showed that PostSharp is not enabled for this project I've added the NuGet package to the new project, which installed a new version of the package in the new Packages subfolder. When I wanted to refer PostSharp from the third project, I've ended up with another version of PostSharp installed. Additionally multiple versions of Diagnostics were created. It definitely causes confusion and errors.   More problems we experienced on build server. According to Using PostSharp on a Build Server "If you chose to deploy PostSharp in the source repository, it does not need to be installed specifically on the build server. " It didn't work on our build server. I kept getting errors "The "AddIns" parameter is not supported by the "PostSharp21" task." and "The "DisableSystemBindingPolicies" parameter is not supported by the "PostSharp21" task."   From my experience the only way to have the latest version of PostSharp working on the build server is to install it using Setup as described in Deploying PostSharp with the Setup Program     Gael acknowledged the issues with possible version conflicts. see http://support.sharpcrafters.com/discussions/problems/388-the-postsharp21-task-failed-unexpectedly

  • Adding my face to my web-site in Google's search result

    - by Roman Matveev
    I'm trying to accomplish the rich snippet to the template of my future web-site. The data format is review and I used the microdata formatting to add all necessary information to the web-page. The Structured Data Testing Tool delivered rating, author information and review date: However there is no my face image and the sections related to authorship are empty: I made all that recommended to link my Google+ profile to the web-site: I did something wrong? Or I will not be able to see my face in the test tools ever and it will be in the real SERP?

  • Should I ditch AJAX in client side web development when I've got a web-socket open?

    - by jt0dd
    I was thinking that maybe I should forget AJAX (HTTP) requests when I've got a web-socket open between client and server, but I decided I should ask here to check if this could be a bad practice for some reason that I'm not thinking of. Once the socket is open, there's less syntax (often meaning simpler error handling) involved in passing information between client and server with Socket.io (just one example of a web-socket). Is there some obvious situation where a web-socket (Socket.io for example) isn't going to be capable of handling a functionality that an AJAX request could do easily?

  • Any Recommendations for a Web Based Large File Transfer System?

    - by Glen Richards
    I'm looking for a server software product that: Allows my users to share large files with: The general public securely to 1 or more people (notification via email, optionally with a token that gives them x period of time to download) Allows anyone in the general public to share files with my users. Perhaps by invitation. Has to be user friendly enough to allow my users to use this with out having to bug me as the admin. It needs to be a system that we can install on our own server (we don't want shared data sitting on anyone else's server) A web based solution. Using some kind or secure comms channel would be good too, eg, ssh Files to share could be over 1 GB. I found the question below. WebDav does not sound user friendly enough: http://serverfault.com/questions/86878/recommendations-for-a-secure-and-simple-dropbox-system I've done a lot of searching, but I can't get the search terms right. There are too many services that provide this, but I want something we can install on our own server. A last resort would be to roll my own. Any ideas appreciated. Glen EDIT Sorry Tom and Jeff but Glen specifically says that he's looking for a 'product' so given that I specialise in this field thought that my expertise in this area may have been of use to him. I don't see how him writing services is going to be easy for him to maintain going forward (large IT admin overhead) or simple for his users and the general public to work with.

  • Which is the best free ide/plugin for struts2?

    - by shahensha
    Hello friends, I have just learnt struts 2 and now I have taken up a full fledged project in it. I learnt the basics of struts 2 in Netbeans with it's struts2 plugin. But I am not at all happy with it, as it is very basic and I end up doing most of the work. It is obviously better than plain-vanilla text editor, but still not at all near to what netbeans provides for springs and hibernate. I know because netbeans provides native support for springs and hibernate, it is meant to be better. I don't mind changing my IDE if i get better support for struts2! So my questions are Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them. Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse. Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links. Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading Struts 2 in Action of Manning publications. Thanking you in advance! regards shahensha

  • How to setup Python with Lighttpd and FastCGI (like PHP)

    - by johndir
    Running Lighttpd on Linux, I would like to be able to execute Python scripts just the way I execute PHP scripts. The goal is to be able to execute arbitrary script files stored in the WWW directory, e.g. http://www.example.com/*.py. I would not like to spawn a new Python instance (interpreter) for every request (like done in regular CGI, if I'm not mistaken), which is why I'm using FastCGI. Following Lighttpd's documentation, the following is the FastCGI part of my config file. The problem is that it always runs the /usr/local/bin/python-fcgi script for every *.py file, regardless of the content of that file: http://www.example.com/script.py [output=>] "python-fcgi: test" (regardless of the content of script.py) I'm not interested in using any framework, but simply executing individual [web] scripts. How can I make it act like PHP, executing any script in the WWW directory by requesting it's path? /etc/lighttpd/conf.d/fastcgi.conf: server.modules += ( "mod_fastcgi" ) index-file.names += ( "index.php" ) fastcgi.server = ( ".php" => ( "localhost" => ( "bin-path" => "/usr/bin/php-cgi", "socket" => "/var/run/lighttpd/php-fastcgi.sock", "max-procs" => 4, # default value "bin-environment" => ( "PHP_FCGI_CHILDREN" => "1", # default value ), "broken-scriptfilename" => "enable" ) ), ".py" => ( "python-fcgi" => ( "socket" => "/var/run/lighttpd/fastcgi.python.socket", "bin-path" => "/usr/local/bin/python-fcgi", "check-local" => "disable", "max-procs" => 1, ) ) ) /usr/local/bin/python-fcgi: #!/usr/bin/python2 def myapp(environ, start_response): start_response('200 OK', [('Content-Type', 'text/plain')]) return ['python-fcgi: test\n'] if __name__ == '__main__': from flup.server.fcgi import WSGIServer WSGIServer(myapp).run()

  • Assign subdomains to separate ports on web server

    - by Michael Frank
    I have set up an Abyss web server as a little experiment, and I want to know if it is possible to assign subdomains to different ports on the machine the web server is running on. I have a couple webUIs that I'd like to assign subdomains: 192.168.1.1:8000 becomes example.com/webui1/ 192.168.1.1:8001 becomes example.com/webui2/ The webUIs are available by accessing their ports via example.com:8000. I have tried using a reverse proxy, but it seems that this is only usable on one internal IP at a time. What other options do I have? Answer is good, but my current set up doesn't meet the requirements. Abyss Web Server X2 is required to use Virtual Hosts with Abyss.

  • PHP and performance

    - by Naif
    I always hear that PHP is for medium and small websites whereas .NET and Java for enterprise applications. My question is about PHP. Why is PHP not a good option for enterprise web applications? Is it because if the web application becomes bigger then PHP will be slower as it is an interpreted language? I know that corporate world will choose .NET or J2EE because of the integration with their products and because of back end services, etc. However, if we just have PHP for building sites and web applications then how can we use it to perform well with big sites? In short, Is there a relationship between the performance of PHP and the size of the website? What are the factors that make PHP not appropriate option for big sites?

  • Passing Parameters Between Web-Services and JSF Pages

    - by shay.shmeltzer
    This is another quick demo that shows a common scenario that combines several demos I did in the past. The scenario – we have two web services, one returns a list of objects, the other allows us to update an object. We want to build a page flow where the first page shows us the list of objects, allows us to select one, and then we can edit that instance in the next page and call the second web service to update our data source. The demo shows: How to select a row and save the object value in a pageFlowScope. (using setPropertyListener). How to create a page that allows me to modify the value of the pageFlowScope object, and how to pass the object as a parameter to the second Web service. Check it out here:

  • java framework for a web wizard

    - by snippl
    I'd like to create a web wizard or a wizard on/within a website. I know there are several java frameworks for wizards but there is none for the web in particular. If I search for a framework, I always get wizards to create a website, applet, servlet and what not. But never how to create such a wizard itself. So the question(s) is: What framework should I use to create a web wizard? And what frameworks are there? The wizard will be the visualisation for a BPEL Process deployment on a apache ode. I thought a webapp would be an easy way because the apache is running anyway. I'm not bound to that, perhaps someone has a better idea.

  • WCF web service with Neural Network

    - by Gary Frank
    I am developing a web service that performs object recognition. It will be available for testing as soon as enough code has been developed, and then officially when it is finished. It is based on a radically new type of artificial neural network that I designed. Its goal is to recognize any type of object within an image. Besides the WCF web service, the project will also create a website to test and demonstrate the web service. Here is a link with more information. http://www.indiegogo.com/VOR

  • Mobile Web or Objective-C?

    Cameron Moll is worried about a future in which we’ll all write Objective-C for the iPhone OS instead of writing web standards for the mobile web.At one point in time, J2ME (now Java ME) and WAP were the starting points for a discussion on mobile strategy and the web. Then, for a brief period of time, you talked about HTML/CSS. Now, for a growing majority of mobile strategies that don’t require a global presence on widely varying devices, the discussion begins with iPhone.Emphasis mine.

  • Dedicated virtual setup is slow with WordPress

    - by kovshenin
    Hey. I'm running a Fedora linux server on the Amazon EC2 platform. I'm pretty sure there's something wrong with my configuration as it seems to be very slow. SSH sometimes takes over 30 seconds to connect, a WordPress generated web page could take 5 seconds to load, and it could take 20 seconds to load, which is pretty awkward. MySQL queries are all executed in less than a second, so I don't think that's the case. I'm not really sure where the issue lies, but a simple page written in PHP loads instantly. A fresh WordPress installation starts lagging. Same works perfect on grid hosting at MediaTemple for instance, so I'm pretty sure I missed something. If you could please direct me to the right tools and articles which would help me out. Thanks so much! Fedora Core 8, php 5.2.6, MySQL 5.0.45, OpenSSH 4.7p1, OpenSSL 0.9.8b. PHP is configured as a module to Apache 2.2.9, all websites based on virtual hosts. I have some on-going php scripts running from time to time in the background via cron. Thanks.

  • The Use-Case Driven Approach to Change Management

    - by Lauren Clark
    In the third entry of the series on OUM and PMI’s Pulse of the Profession, we took a look at the continued importance of change management and risk management. The topic of change management and OUM’s use-case driven approach has come up in few recent conversations. So I thought I would jot down a few thoughts on how the use-case driven approach aids a project team in managing the project’s scope. The use-case model is one of several tools in OUM that is used to establish and manage the project's scope.  Because a use-case model can be understood by both business and IT project team members, it can serve as a bridge for ongoing collaboration as well as a visual diagram that encapsulates all agreed-upon functionality. This makes it a vital artifact in identifying changes to the project’s scope. Here are some of the primary benefits of using the use-case model as part of the effort for establishing and managing project scope: The use-case model quickly communicates scope in a straightforward manner. All project stakeholders can have a common foundation for the decisions regarding architecture and design and how they relate to the project's objectives. Once agreed upon, the model can be put under change control and any updates to the model can then be quickly identified as potentially affecting the project’s scope.  Changes requested or discovered later in the project can be analyzed objectively for their impact on project's budget, resources and schedule. A modular foundation for the design of the software solution can be established in Elaboration.  This permits work to be divided up effectively and executed in so that the most important and riskiest use-cases can be tackled early in the project. The use-case model helps the team make informed decisions about implementation priorities, which allows effective allocation of limited project resources.  This is very helpful in not only managing scope, but in doing iterative and incremental planning which relies heavily on the ability to identify project priorities. Bottom line is that the use-case model gives the project team solid understanding of scope early in the project.  Combine this understanding with effective project management and communication and you have an effective tool for reducing the risk of overruns in budget and/or time due to out of control scope changes. Now that you’ve had a chance to read these thoughts on the use-case model and project scope, please let me know your feedback based on your experience.

  • Create an Asynchronous JAX-WS Web Service and call it from Oracle BPEL 11g

    - by Bob Webster
    This posting is the result of a simple requirement to take an existing JAX-WS Web service,convert it to be asynchronous and call it from Oracle BPEL 11g It turned out that this is not a trivial task... BPEL has some very specific expectations about the WSDL for an asynchronous process. One approach is to develop the service starting from a WSDL document that meets BPEL's requirements. This is possible but requires considerable WSDL authoring skills. The other approach is to modify the WSDL generated by Web Service Annotations in Java code (Bottom up development) and instruct JAX-WS to use that WSDL instead of dynamically generating one from annotations. This is the approach taken in this article. This posting details how to: Modify a JAX-WS Web Service developed using a "Bottom up " approach to have an asynchronous method and callback. Call the Asynchronous Service from Oracle BPEL 11g. Read the full posting here.

  • Packaging a web application for deploying at customer site

    - by chitti
    I want to develop a django webapp that would get deployed at the customer site. The web app would run in a private cloud environment (ESX server here) of the customer. My web app would use a mysql database. The problem is I would not have direct access/control of the webapp. My question is, how to package such a web application with it's database and other entities so that it's easier to upgrade/update the app and it's database in future. Right now the idea I have is that I would provide a vm with the django app and database setup. The customer can just start the vm and he would have the webapp running. What are the other options I should consider?

  • Evidence for automatic browsing - Log file analysis

    - by Nilani Algiriyage
    I'm analyzing web server logs both in Apache and IIS log formats. I want to find the evidence for automatic browsing, like web robots, spiders, bots, etc. I used python robot-detection 0.2.8 for detecting robots in my log files, but I know there may be other robots (automatic programs) which have traversed through the web site but robot-detection can not identify. So I want to ask: Are there any specific clues that can be found in log files that human users do not leave but automated software would? Do they follow a specific navigation pattern? I saw some requests for favicon.ico - does this implicate that it is a automatic browsing?. I found this article and this question with some valuable points.

  • Deprecate a web API: Best Practices?

    - by TheLQ
    Eventually you need to depreciate parts of your public web API. However I'm confused on what would be the best way to do it. If you have a large 3rd party app base just yanking old versions of the API seems like the wrong way to do it as almost all apps would fail overnight. However you can't keep ancient web api's available forever as it might be outdated or there are significant changes that make working with it impossible. What are some best practices for deprecating old web api's?
