• How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

  - by Luis Alvarado

  I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

• Confused about ASP.NET Ajax, jQuery and JavaScript

  - by Mr.Y

  Yesterday, I read couple of chapters on ASP.NET Ajax and jQuery from my ASP.NET 4 book and I found those frameworks pretty interesting and decide to learn more about them. Today, I borrowed some books from library on Ajax and JavaScript. It seems ASP.NET Ajax is different from Ajax and jQuery seems like the "new" JavaScript. Does it mean that I can skip JavaScript and learn jQuery directly? On the other hand, the non-ASP.NET Ajax book I borrowed seems to apply to the client side web programming only and looks quite different from what I learned from ASP.NET Ajax. If I'm an ASP.NET developer, I guess I should stick with ASP.NET Ajax instead of client side Ajax right? What about PHP? Is there a "PHP Ajax" similar to ASP.NET Ajax? It's not that I'm lazy to learn other tools, but I just want to focus on the right ones.

• Thoughts of Cloud Development/Google App Engine

  - by jiewmeng

  I use mainly PHP for web development, but recently, I started thinking about using Google App Engine. It doesn't use PHP which I am already familiar with, so there will be a steeper learning curve. Probably using Python/Django. But I think it maybe worthwhile. Some advantages I see: Focus on App/Development. No need to setup/maintain server ... no more server configs Scales automatically Pay for what you use. Free for low usage Reliable, it's Google after all Some concerns though: Does database with no joins pose a problem for those who used App Engine before? Do I have to upload to Google just to test? Will it be slow compared to testing locally? What are your thoughts and opinions? Why would you use or not use App Engine?

• Secure Yourself by Using Two-Step Verification on These 16 Web Services

  - by Chris Hoffman

  Two-factor authentication, also known as 2-step verification, provides additional security for your online accounts. Even if someone discovers your password, they’ll need a special one-time code to log in after you enable two-factor authentication on these services. Notably absent from this list are banks and other financial institutions. It’s a shame that you can use two-factor authentication to protect your in-game currency in an MMORPG, but not the real money in your bank account.

• REST API rule about tunneling

  - by miku

  Just read this in the REST API Rulebook: GET and POST must not be used to tunnel other request methods. Tunneling refers to any abuse of HTTP that masks or misrepresents a message’s intent and undermines the protocol’s transparency. A REST API must not compromise its design by misusing HTTP’s request methods in an effort to accommodate clients with limited HTTP vocabulary. Always make proper use of the HTTP methods as specified by the rules in this section. [highlights by me] But then a lot of frameworks use tunneling to expose REST interfaces via HTML forms, since <form> knows only about GET and POST. My most recent example is a MethodRewriteMiddleware for flask (submitted by the author of the framework): http://flask.pocoo.org/snippets/38/. Any ways to comply to the "Rule" without hacks or add-ons in web frameworks?

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank

• Host And Expose Application to local small network

  - by tartak

  I developed a little application (web application) using JavaEE+MySql. I try to keep some data and .. from time to time to get some reports using my data. My problem is I have to access this application from 4-5 computers in the office. They are connected through a switch. It's a typical small office network, nothing fancy. I need some advice on how to do this. I mean for a small application with no external communication is it mandatory to use an Apache machine? I'd use a simple Tomcat container on the "server machine" (which is my computer, a windows machine) and .. basically .. I would like to permit the access to my colleagues also. I don't have any knowledge about concurrency (I know mysql permits concurrent access) so I would like some configuration tips also.

• How can I find installed web applications?

  - by Jo-Erlend Schinstad

  I've installed LAMP Server using tasksel. I've installed phpMyAdmin, which I know from experience gets in /phpmyadmin. That works. Then I installed drupal6. I assumed that it would get in /drupal, but that's not the case. How can I find that kind of information? Of course, in this case, I'm looking for my Drupal install, but I would like to avoid having to spend so much time every time I install a web application, so I'm looking for a generic way.

• DNS Configuration when registrar and host are two different companies

  - by dclowd9901

  I'm a total noob when it comes to DNS configuration. My client bought a domain through one company and is hosting their site with another (a virtual dedicated server). I can't find anything on the web that explains one's way through this setup. Where do I start? Which nameservers do I use? Which company's zone files do I edit? Basically it boils down, for me that I don't understand which company takes the lead, and which piggybacks off their configuration. Thanks in advance for the help.

• Ways of Gathering Event Information From the Internet

  - by Ciwan

  What are the best ways of gathering information on events (any type) from the internet ? Keeping in mind that different websites will present information in different ways. I was thinking 'smart' web crawlers, but that can turn out to be extremely challenging, simply because of the hugely varied ways that different sites present their information. Then I was thinking of sifting through the official twitter feeds of organisations, people with knowledge of events .. etc and look for the event hash tag, grab the tweet and dissect it to grab the relevant information about the event. Information I am interested in gathering is: Date and Time of Event, Address where Event is being held, and any Celebrities (or any famous people) attending the event (if any). The reason to ask here is my hope that experienced folk will open my eyes to things I've missed, which I am sure I have.

• Unable to start the web application from localhost:3000(ruby on rails)

  - by vipin8169

  I had created a demo web application by executing rails tickets and then i executed rails script/server to run it on localhost. Initially i was able to execute the application in the browser by typing localhost:3000 in the address bar, but then I deleted the folder tickets from my hard disk. Now again i created the same folder but when i try to run it using the same command rails script/server it says that vverma@l-vverma:~/railsExp/tickets$ rails script/server create File exists - script/server I tried deleting the script/server file but i still couldn't run the localhost:3000 in the browser Tried rails s as well, it gave the following output:- http://paste.ubuntu.com/1317610/ But still i was unable to run the app on 'localhost:3000' What is the solution to this

• Should I use title case in URLs?

  - by Amadiere

  We are currently deciding on a consistent naming convention across a site with multiple web applications. Historically, I've been an advocate of the 'lowercase all the letters!' when creating URLs: http://example.com/mysystem/account/view/1551 However, within the last year or two, specifically since I began using ASP.NET MVC & had more dealings with REST based URLs, I've become a fan of capitalizing the first letter of each section/word within the URL as it makes it easier to read (imho). http://example.com/MySystem/Account/View/1551 We're not in a situation where people need to read or be able to understand the URLs, so that's not a driver per se. The main thing we are after is a consistent approach that is rational and makes sense. Are there any standards that declare it good to do one way or another, or issues that we may run into on (at least realistically modern) setups that would choose a preference over another? What is the general consensus for this debate currently?

• running jar in a terminal using axis2

  - by Emilio

  I'm trying to run in the command line a java application distributed in a jar file. It call an axis2 web service, so the jar contains a /axis2client directory with rampart.mar security module. It works fine while I run it in netbeans, but it throws an exception if I try to run it in a terminal using this command: java -jar myfile.jar The Exception: org.apache.axis2.AxisFault: invalid url: //file:/home/xxx/Desktop/myfile.jar!/axis2client/ (java.net.MalformedURLException: no protocol: //file:/home/xxx/Desktop/myfile.jar) As you can see, it's trying to use the /axis2client directory inside the jar, as when I run it in Netbeans, but It fails with a MalformedURLException. I think it's something about the protocol 'file:', probably '//file:/' must be 'file:///'. The problem is that I cannot change this call to the directory because the method that loads the /axis2client directory it's not mine, it's from another library that use my project and include all the axis2 support. So, any idea?? Thanks in advance lads!

• Significance and role of Node.js in Web development

  - by Pankaj Upadhyay

  I have read that Node.js is a server-side javascript enviroment. This has put few thought and tinkers in my mind. Can we develop a complete data-drivent web application utilizing just JavaScript (along with node.js), HTML5 and CSS? Do we still need to use some server-side scripting language (e.g. C#, PHP)? In case we still need to use other scripting languages, what is node.js worth for, or useful? NOTE: Pardon with my knowledge about node.js.

• Checking for cross-site scripting vulnerabilities in Perl web applications

  - by David Scholefield

  I'm putting together some notes for a dev team on how to write secure Perl code - especially taking into account the current OWASP top 10 web application vulnerabilities. For cross-site scripting I've included information on ensuring that all output to the browser is checked and escaped where necessary, but I'm looking for more automated mechanisms that would mean a developer doesn't have to think about every output statement and, potentially, miss one. Perl's 'taint' function sounds like it should be a help because it distrusts all user input, but it doesn't complain on tainted data being output to the browser. Apart from checking all output statements individually (probably by calling a generic sanitizing function) does anyone have any ideas on how Perl can help with this with existing libraries or techniques?

• What version of Java should I target for applets?

  - by Christopher Horenstein

  I recently deployed an applet that seems to require Java 6 Update 24. I assume the reason for this requirement is the matching JDK version I used to create the applet (I am new to Java). The fact that my applet requires a Java download/update for users who already have some version of Java installed is a big concern for me; the applets I'm creating slip into a web comic, so it's very disruptive. Having used the most recent version of Java, it seems as though I am able to assume that most of the readers I get will have to update Java to continue reading/playing. Is there a best practice concerning which version of Java to use to make the process of using an applet easy for end-users? Any reading material on this would be very helpful. Should I be using an older version of Java if I don't require new features? I am using Slick for 2D games.
