  • I would like to build an app that alerts me when road traffic is high or low. Where can I get the r

    - by MedicineMan
    I'm sitting at work, waiting for traffic to die down. The thought occurred to me. I know when I want to go home, why don't I have an app that watches traffic for me? I also know that there are a lot of smart people on stackoverflow. Where can I get live traffic data for the san francisco bay area region? The data source should be timely, accurate, and as high resolution as possible. I would like to build an app on top of a service, rather than watch google maps or watch another website. I would prefer that I not have to scrape the data, but I have been know to do this in the past when no other option exists.

  • How to clear a bean field with Stripes.

    - by Davoink
    In a JSP I have the following field: <stripes:text name="email"/> This field is in my action bean(snippet): public class CreateClaim implements ActionBean { private String email; public void setEmail(String email) { this.email = email; } public String getEmail() { return email; } public Resolution alc(){ email = "poodle"; return new ForwardResolution("aForward.jsp"); } } In the alc() methos I am setting email to be null. But when the pages renders the value of the email field is exactly as it was entered originally. Is there a way of clearing this field once and event has triggered? Cheers Dave

  • MVC design question for forms

    - by kenny99
    Hi, I'm developing an app which has a large amount of related form data to be handled. I'm using a MVC structure and all of the related data is represented in my models, along with the handling of data validation from form submissions. I'm looking for some advice on a good way to approach laying out my controllers - basically I will have a huge form which will be broken down into manageable categories (similar to a credit card app) where the user progresses through each stage/category filling out the answers. All of these form categories are related to the main relation/object, but not to each other. Does it make more sense to have each subform/category as a method in the main controller class (which will make that one controller fairly massive), or would it be better to break each category into a subclass of the main controller? It may be just for neatness that the second approach is better, but I'm struggling to see much of a difference between either creating a new method for each category (which communicates with the model and outputs errors/success) or creating a new controller to handle the same functionality. Thanks in advance for any guidance!

  • REST API error return good practices

    - by Remus Rusanu
    I'm looking for guidance on good practices when it comes to return errors from a REST API. I'm working on a new API so I can take it any direction right now. My content type is XML at the moment, but I plan to support JSON in future. I am now adding some error cases, like for instance a client attempts to add a new resource but has exceeded his storage quota. I am already handling certain error cases with HTTP status codes (401 for authentication, 403 for authorization and 404 for plain bad request URIs). I looked over the blessed HTTP error codes but none of the 400-417 range seems right to report application specific errors. So at first I was tempted to return my application error with 200 OK and a specific XML payload (ie. Pay us more and you'll get the storage you need!) but I stopped to think about it and it seems to soapy (/shrug in horror). Besides it feels like I'm splitting the error responses into distinct cases, as some are http status code driven and other are content driven. So what is the SO crowd recommendation? Good practices (please explain why!) and also, from a client pov, what kind of error handling in the REST API makes life easier for the client code?

  • Is there an online user agent database?

    - by Gary Richardson
    How do you parse your user agent strings? I'm looking to get: Browser Browser Version OS OS Version from a user agent string. My app is written in perl and was previously using HTTP::BrowserDetect. It's a bit dated and is no longer maintained. I'm in no way tied to using perl for the actual lookup. I've come to the conclusion that automagic parsing is a lost cause. I was thinking of writing a crud type app to show me a list of unclassified UA's and manually keep them up to date. Does such an resource already exist that I can tap into? It would be awesome if I could make an HTTP call to look up the user agent info. Thanks!

  • best way to switch between secure and unsecure connection without bugging the user

    - by Brian Lang
    The problem I am trying to tackle is simple. I have two pages - the first is a registration page, I take in a few fields from the user, once they submit it takes them to another page that processes the data, stores it to a database, and if successful, gives a confirmation message. Here is my issue - the data from the user is sensitive - as in, I'm using an https connection to ensure no eavesdropping. After that is sent to the database, I'd like on the confirmation page to do some nifty things like Google Maps navigation (this is for a time reservation application). The problem is by using the Google Maps api, I'd be linking to items through a unsecure source, which in turn prompts the user with a nasty warning message. I've browsed around, Google has an alternative to enterprise clients, but it costs $10,000 a year. What I am hoping is to find a workaround - use a secure connection to take in the data, and after it is processed, bring them to a page that isn't secure and allows me to utilize the Google Maps API. If any of you have a Netflix account you can see exactly what I would like to do when you sign-in, it is a secure page, which then takes you to your account / queue, on an unsecure page. Any suggestions? Thanks!

  • Setting multiple SMTP settings in web.config?

    - by alphadogg
    I am building an app that needs to dynamically/programatically know of and use different SMTP settings when sending email. I'm used to using the system.net/mailSettings approach, but as I understand it, that only allows one SMTP connection definition at a time, used by SmtpClient(). However, I need more of a connectionStrings-like approach, where I can pull a set of settings based on a key/name. Any recommendations? I'm open to skipping the tradintional SmtpClient/mailSettings approach, and I think will have to...

  • Web based delivery pricing system - where to start?

    - by jsims281
    I've been asked to quote on how long it would take to deliver a system such as can be found here: http://cgi.tnt.co.uk/ratechecker/enter_details.asp The client basically wants to give quotes for shipping based on a number of variables such as weight, distance etc, and for it to be accessible through their website. I've thought of the Drupal/Ubercart/Shipping combination but this isn't really what it's designed for. A paid for, off-the-shelf system would also be great but I can't seem to find any that do this properly.. What would be a good system to start with here, or alternatively is there a system that already does this?

  • Java/Swing: the fast/slow UI binding problem

    - by Jason S
    I need a way to bind UI indicators to rapidly-changing values. I have a class NumberCruncher which does a bunch of heavy processing in a critical non-UI thread, thousands of iterations of a loop per second, and some number of those result in changes to a set of parameters I care about. (think of them as a key-value store) I want to display those at a slower rate in the UI thread; 10-20Hz would be fine. How can I add MVC-style notification so that my NumberCruncher code doesn't need to know about the UI code/binding?

  • Frameworks for JavaScript UI Widgets?

    - by ChrisInCambo
    I'm trying to put together a list of JavaScript UI widget frameworks for consideration in a project. Ideally it would be a library that has a range of ready made ui widgets, no dependencies on dom/js extention/manipulation frameworks like JQuery or Prototype, minimal additional cruft, such as Ajax API's and DOM selectors etc. Here's what I have so far: qooxdoo, ScriptClient ExtJs Could anyone suggest any other that are worth a look? Please do not suggest, JQuery, Prototype, Mootools, Dojo etc, their primary focus is not to provide ui widgets.

  • How to include frameset under CGI.pm

    - by neversaint
    I want to have a cgi-script that does two things. Take the input from a form. Generate results base on the input values on a frame. Primarily I want the frame exist only after the results is generated/printed. Below is the simplified code of what I want to do. But somehow it doesn't work. What's the right way to do it? #!/usr/local/bin/perl use CGI ':standard'; print header; print start_html('A Simple Example'), h1('A Simple Example'), start_form, "What's your name? ",textfield('name'), p, "What's the combination?", p, checkbox_group(-name=>'words', -values=>['eenie','meenie','minie','moe'], -defaults=>['eenie','minie']), p, "What's your favorite color? ", popup_menu(-name=>'color', -values=>['red','green','blue','chartreuse']), p, submit, end_form, hr; if (param()) { # begin create the frame print <<EOF; <html><head><title>$TITLE</title></head> <frameset rows="10,90"> <frame src="$script_name/query" name="query"> <frame src="$script_name/response" name="response"> </frameset> EOF # Finish creating frame print "Your name is: ",em(param('name')), p, "The keywords are: ",em(join(", ",param('words'))), p, "Your favorite color is: ",em(param('color')), hr; } print end_html;

  • What exactly is a web application framework?

    - by isaiah
    I'm getting into python for cgi and came across Django. I'm not quite sure I understand it very much. Is it something I have to install inside apache or is it just something I can use with my cgi? Wanted to know because I'd love to learn it but my server I'm using doesn't give me a lot of privileges. thanks

  • Web form / CGI scripting: User enters "word", IFrame displays "word".html

    - by Haskella
    Okay, I'll admit being a designer, I don't know much about how data is handled from the servers in forms... (basically the whole programming part). Basically I have a text field that the user types something like "apple", this gets sent to the server and then displays the apple.html page that I have in a directory in an IFrame. If anyone can show me how to do this in a PHP script or Perl, would be great thanks! I think this is good start, it gets more complicated than this... I later have to convert the "apple" into something like 2321 and display 2321.html instead. If anyone can find a CGI script that does this, thanks!

  • web design question (php/ajax)

    - by tom smith
    Hi guys... Hope this isn't a waste of your time. I'm working on a project, and it occured to me that there's a chunk of code out there, that should allow me to see how others have implemented this. I've got a project where I'm going to have a page, with a sel box. the user will select an item from the selList, and based on the item selected, a separate section of the page (areaB) will change in terms of the content/tbls being displayed. i then want to allow the user to go through a series of subpages in areaB, where the user goes through a submit/cancel/confirm process, where the stuff in areaB changes, with the rest of the page remaining the same... i'm trying to figure out the best approach to implement the on both client/server side. i could just have an ugly "if block" where i have abunch of logic, and i completely regen the page each time the user selects an action.. i could have an approach that might involve divs/frames, where i then just regen the targeted frame/div area.. is this even possible?? i could have some form of ajaxy process, which would only alter the targeted section(s) of the page... so.. i'm trying to talk to anyone who has ideas on how to do this, or more ideally, if you know of a good code (client/server) side example of this... that i can examine. i'd really appreciate it!! i've got a more detailed overview but didn't know if it would be cool to post it here... thanks.. tom
