  • Give away signs that a site is Drupal?

    - by RD
    I'm trying to alter my site in such a way so that when people view it, they don't know it's powered by Drupal. So, was wondering if there are any signs that give this away that I should know about? Some of the giveaways I know of, are: When adding content, it will say "node/add". If the following file exists: misc/favicon.ico etc I'm looking for similar stuff?

  • The use of Javascript - stats?

    - by Luke
    I am looking at redesigning my website and was wondering if I could get some opinions. I know that the rule is usually to design with users without JS first and foremost, but having looked at the stats, it appears 95% of the users online have JS enabled. Would you recommend designing the website using JS and not bothering about people without it?

  • Distributing iPhone App to developers in your team through iTunes

    - by Rudiger
    Hi everyone, Was wondering if you can distribute your App to other developers in your team through iTunes. I guess you would upload the App as a beta version through iTunes Connect and anyone with a provisioned iPhone would receive the update. I didn't think it was possible but someone told me they were sure you could. If this is not possible are there any other benefits of a company standard enrolment besides being able to add other people so they can get the same resources? Thanks

  • Dispose a Web Service Proxy class?

    - by Matt
    When you create and use a Web Service proxy class in the ASP.Net framework, the class ultimately inherits from Component, which implements IDisposable. I have never seen one example online where people dispose of a web proxy class, but was wondering if it really needs to be done. When I call only one method, I normally wrap it in a using statement, but if I have a need to call it several times throughout the page, I might end up using the same instance, and just wondered what the ramifications are of not disposing it.

  • Encrypt/ Secure communication Android app <-> REST webservice

    - by Ascorbin
    I want to create a backend for my android app with Tapestry5 and this http://code.google.com/p/t5-restful-webservices/ plugin. The app will communicate with the server by calling REST methods both for registered users (that would be easy to secure I guess) as well as unregistered users. Now of course I don't want people to just call that webservice from a browser. How can I make sure that only my app can make calls to this backend?

  • What do you use two monitors for when you develop?

    - by Yishai
    Although I have two monitors on my desk, I just find that I don't use the second one very often. I see that often people are extolling the virtues of two (or three) monitors, but I haven't gotten into the groove. It gets me thinking that I may be missing some productivity techniques. So how do you organize your two monitors?

  • Generic CSS templates anywhere (not layout)?

    - by TruMan1
    I am looking for a place where I can download a bunch of CSS stylesheets to change the appearance of my titles, links, paragraphs, etc. I am not an artist, so I am hoping to leverage other people's skills in choosing the right fonts, colors, sizes, etc. I do not want to include layout because then it won't be as generic. Does anyone know where I can get something like this?

  • Git/SVN for asp.net development instead of VSS?

    - by jrutter
    At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.
