  • Performance of a proposed JEE architecture

    - by kineas
    I have concerns about the performance of the following architecture: j2ee application in an appserver, ejb session bean and DAOs remote (rich) client, a swing app. A classic, form-based client only one stateless ejb, the ejb is accessed via web services, not rmi, through a homegrown framework each web service request will get authenticated against an LDAP no state stored on the server, only client-side sessions I guess working on the rich GUI will involve a remote call in every 2-10 seconds, or more, per user. What do you think?

  • Working with PHP Octals and String conversions

    - by krio
    I'm working with a database that has a bunch of serial numbers that are prefixed with leading 0's. So a serial number can look like 00032432 or 56332432. Problem is with PHP I don't understand how the conversion system with octals works. A specific example is that I'm trying to convert and compare all of these integer based numbers with strings. Is it possible to convert an octal, such as 00234 to a string like "00234" so that I can compare it?

  • How to read date from the form and calculate a timestamp

    - by Vafello
    I would like to calculate a timestamp based on the input date. I would like to calculate it from the user input (something like 12/12/2011) I guess I need a function that changes the format to something readable for php and then calculate timestamp for this date. Maybe I should use strtotime() function? Any ideas will be appreciated. $date = $_POST['date']; <input type="text" name="date" value="">

  • Javascript static method intheritance

    - by Matteo Pagliazzi
    I want to create a javascript class/object that allow me to have various method: Model class Model.all() » static method Model.find() » static method Model delete() » instance method Model save() » instance method Model.create() » static that returns a new Model instance For static method I can define them using: Model.staticMethod(){ method } while for instance method is better to use: function Model(){ this.instanceMethod = function(){} } and then create a new instance or using prototype? var m = function Model(){ } m.prototype.method() = function(){ } Now let's say that I want to create a new class based on Model, how to inherit not only its prototypes but also its static methods?

  • wii motionplus support

    - by Richard
    hello, I am developing a PC application that interacts with the Wii Remote. So far I have been using the wiiuse library, which has worked great. However wiiuse does not support the MotionPlus extension. I have heard of extensions to implement this by Dolphin and libogc but have not managed to locate this code. Do you know of code that implements support for MotionPlus with wiiuse, or another C based libary?

  • Moving files between Windows computers without creating network shares

    - by mavnn
    What's needed: To move several directories between two Windows 2008 servers on a regular basis. Due to security requirements, neither server is supposed to have network shares set up or extraneous software installed. What's available: Administrator access to both machines (including remote desktop access if that helps). A third machine with: Visual Studio 2010 Cygwin Bonus extras The script that does the rest of the work (apart from moving the files) is currently written in F#, but any .net/command line based solution would be fine.

    There doesn't seem to be (to my knowledge) an API to edit Google Docs (not spreadsheets, their HTML based documents). Has anyone done something like the? Maybe by downloading the HTML version, editing and uploading the changes?

  • software for sorting algorithms animation

    - by Dinesh
    I am planning on working on an interactive application that graphically animates the various sorting algorithms in action. Most of the examples of this kind on the web seems to be using java applets. I was wondering what other software/tools would be well suited to develop an application like this. It may or may not be web-based. Any help would be greatly appreciated. Thanks Dinesh

  • Shake to open view modally

    - by Vivas
    Hi, I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController. In my appdelegate I have the notification (as per the GLPaint sample code): [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeToOpenHiddenScreen) name:@"shake" object:nil]; In my shakeToOpenHiddenScreen I just want to open view 'x' modally but I don't think that my appdelegate will respond to presentModalViewController. Is there a way around this?

  • Good object/DB set-up for CMS-esque app for managing content and user permissions?

    - by sah302
    Hi all, so I am writing a big CMS-esque app to allow users to manage web content through web applications, I've got a pretty good db-driven user permission system going, but am having trouble coming up with a good way to handle content groups and pages, I've got a couple options and not sure which one to take. Furthermore, I am not sure how to handle static page updates that have no 'widgets' in them. My current set-up for permissions is this: Objects: User, UserGroup, UserUserGroup, UserGroupType Standard many to many relationship User -> UserUserGroup <- UserGroup each Usergroup has a UserGroupType, which could be anything from Title, Department, to PermissionGroup. PermissionGroup manages the permissions. Right now on a per page basis I check permissions based on their PermissionsGroups. So for a page which has CMS features for a news widget, I check for permission groups of "Site Admin" and "News Admin". Now the issue I am coming to is, the site has many different departments involved. No problem I think, I can just have a EntityContentGroup so any widget app can be used for any departments. So my HR department, each of their news items would be in the EntityContentGroup with the news item ID, and content group of "HR" or "HR News". But maybe this isn't the most efficient way to go about it? I don't want to put the content group simply as a NewsItemType because some news items could apply to multiple areas, so I want to be able to assign them to as many areas as I want. Likewise, all of my widget apps have this, so that's why I decided to choose EntityContentGroup and not just NewsItemContentGroup. I was also thinking well instead of doing a contentGroup do a Page object that says which page some entity should be on. It seems almost like the same thing, but would I want to use Page for something else? I was thinking Page would be used for static pages with no widgets, a simple Rich Text Editor can edit the content of that page and I save that item to a page?? And then instead of doing a page level check for UserGroup permissions, would it be better to associate a usergroup to a contentgroup, and then just depending on what contentGroup content on the page is displayed, determine the permissions through that relationship? Is that better? I am not sure at this point. I guess I am just getting a tad overwhelmed at this is the largest app in scope and size that I have ever written. What is the best approach for this based on my current user permission set-up?

  • Codeigniter: Submitting Forms

    - by Kevin Brown
    How do I submit a form that can do two different things based on the URI? For example, if the URI contains a string "new" the form will submit differently than it would if "new" were not in the URI. I'm having trouble implementing this, as when a form is submitted, it takes the URI of whatever "form_open" says.

  • How to make per- http Request cache in ASP.NET 3.5

    - by Artem
    We using ASP.NET 3.5 (Controls-based apporach) and need to have storage specific for one http request only. Thread-specific cache with keys from session id won't work because threads are supposed to be pooled and therefore I have a chance to have data from some previous request in cache, which is undesireble in my case. I always need to have brand new storage for each request available through whole request. Any ideas how to do it in ASP.NET 3.5?

  • Is It Possible to get a (rough) Mobile Phone Location from a HTTP Request

    - by Tim Lytle
    If memory serves me correctly, google does this for the maps site. I know google's mobile maps app can determine the rough location (I assume using some kind of cell tower lookup), yet I seem to remember the site getting somewhat close to the current location when viewing on a mobile browser. Anyone know how/if that's possible? Does the IP address change based on the tower or area (seems like they'd be using some kind of gateway common to the carrier)?

  • Lighttpd check request headers in configuration

    - by Mike Hayes
    Hi I was wondering if it was possible in the configuration of Lighttpd to read request headers, I've searched and searched.. apparently it's not possible. For example, conditional configuration based upon IP address: $HTTP["remoteip"] == "0.0.0.0" { // Do something } Is there something similar to check headers, for example: $HTTP["X-Some-Header"] == "Value" { // Do something } I'm thinking there isn't but thought I would post here as a last resort. Google didn't help much, and Lighttpd documentation would suggest this is not possible. Thanks Mike
