  • REST API unauthenticated requests exception based on the User-Agent

    - by Shay Tsadok
    Hi All, I am developing a REST API that supports two kinds of authentication protocols: login form authentication - for browser based clients. Simple Basic authentication - for non-browser clients. I developed a flow in which unauthenticated requests redirected to the "login form", the problem is that this is an undesired behavior for non-borwser clients! I thought to solve it by decide according to the "User-Agent" what to do: browsers will be redirected to the "login form" and non-browser clients will get the standard 401:Basic Authentication. A. What do you think about this solution? B. Is there a standard way in Java to check if the request came from browser, or do i need to develop this kind of mechanism by my own? Thanks in advance!

  • Create Personalized Controls For Java ME

    - by Nathan Campos
    I'm starting to develop a eBook reader for mobile using Java ME, but for the control were the book will be shown I need a personalized control. For this I need to first know how to do one, to workaround with my needs. Then I need to know how can I do a personalized control as we do with Visual Basic. PS: I want to do a personalized TextBox, that in some parts can be in bold, italic, sublined, that supports topics(as the Edit, the MS-DOS Text Editor) and many other things that make a eBook better viewed than a simple plain text

  • Advice needed: What tech expertise do I need to accomplish my goal?

    - by quaternion
    I have a business plan & money to hire a developer - the essentials involve simple online games for children (played via traditional computer over the internet) such that their scores are uploaded to a database that can be viewed via a nice portal. What I don't know is: what technologies I would want my developer to know (the only somewhat unusual requirement I have is that the games have relatively accurate timing of keypresses/mouse presses) how much I should expect to pay (in general, what is the appropriate range) how many hours a program of the complexity of a simple tower defense -type game should take to develop (to be clear, the idea is not to implement TD, but rather other games of similar complexity) whether I should go with capable acquaintances, some online kind of online web-dev bidding site, or just try to find a capable undergraduate at the local university who I can wow with his/her first big paycheck, how I should communicate the software's specifications to my hired developer... Is there a standard I should be using? whether I should hire a webdev consultant for a few hours to help me answer these questions, instead of asking stackoverflow Thanks for any advice!

  • A new method of supporting FOSS?

    - by James
    I have been kicking an idea around for sometime and wondered if something of it's nature hadn't already been invented. The premise is a website that integrates code management, project/team management, and micro-transactions. Donations, in and of themselves, are a sporadic, and unreliable method of supporting developers. Furthermore most free software that accepts donations is started by programmers ,be it to learn, because of a hobby, or because they saw a niche that needed to be filled. There is no method in place of of saying "hay, the FOSS community needs this kind of software, will someone develop it, and accept donations!?" Programmers should be programming, not busy begging for money. Basically the idea is people can go to the site in question, and start a project or make a request. Anyone signed up with the site can start a request. Each member account is free to support or "upvote" a project request. Requests and the associated number of votes let programmers in the community know the needs of the community. When a project is started a request for developers can be put forth. Developers have a ranking based on commits to other projects. The project founder can send invites to known Developers, or accept invites from members based on developer ranking. Once the project has at least one team-member, an objectives sheet or "draft" can be put out, listing design, goals, and features. The founding member and each team-member may contribute to this sheet. Each "milestone", or "Feature" is represented by an article. An article is any unit of a draft that can be voted on by The Project Founder, Team-members, and contributors...which brings me to the next half of this idea. --Microtransactions-- People signed up with this hypothetical website can purchase credits which then can be transfered to projects they would like to support. Anyone who transfers credits to a project is known as a contributor to that project. At anytime a Founder, or the lead team-member may submit an article, or a design (multiple articles) for consideration. All team-members, as well as the Founder, can vote once for each article freely. Contributors may vote yes or no on a number of articles (independent of any given meeting where a particular design or article is considered) equal to the number of credits they have placed into a contributors fund for that particular project. A contributors fund is a proxy between a sites credit account, and a projects credit account. It is sort of like a promise to contribute, instead of an actual contribution. Contributers may place constraints on particular articles such that if those constraints (a yes or no vote) are satisfied then a manually specified amount of credits is automatically transfered to the project account. This allows a project to develop based on the needs of those who may (in the future) financially rely on the project. --- Code commits & milestones --- When a team-member makes a commit, they may specify if it's a minor commit, a bug fix, a compatibility patch (i.e. for a new platform), or a milestone (an article voted on previously). People signed up with the website, may download the updated project and test it to see if the programmer's assertion is true about the commit. A report may then be filed on a small form, giving a one or two paragraphs, and a positive or negative confirmation of the programmer's goal for that particular commit. After all milestones for a particular draft are complete, a new draft is submitted for voting. Also funds may withdrawn by each team-member based on the proportion of commits and milestones confirmed (fulfilled the stated purpose) for each programmer. --- voting --- Members, contributor, and non-contributor, may make priority requests for particular articles of a draft. The project founder may or may not opt to fill those requests based on the volume of upvotes. A fulfilled priority request means that any team-member that makes a community-confirmed commit for an article is, when all articles for the draft are fulfilled, granted a portion of project credits in proportion to the average priority of all the articles he committed. ---- Notes --- While this is horribly prone to design-by-committee the one saving grace is that the lead team-member may place constraints on a draft such that some, or ALL articles must be voted yes. Commits may not begin until a draft satisfying said constraints is approved. What does SO think, is this idea feasible? Does anyone see major problems with this? Is there any insights, or improvements that could be made?

  • Having an online highscore leaderboard for a Flash game

    - by Marco Fox
    Why, hello there. I'm trying to develop a simple Flash game using Actionscript 2 (I know its a bit dated, but its a simple project that doesen't benefict much from AS3), and I came up with an ideia of implementing an online leaderboard that records and shows the highscore of the player. This isn't anything too complicated, but I seem to be having problem finding resources online that explain how I should implement this. All I want is a call, probably to a PHP/MySQL database that records the player's name (which will be recorded via a input window) and its current score. It would also have to show the best all time scores, by order. I should remind you that I am working on a Actionscript 2 so Actionscript 3 solutions are probably not going to work. Can anyone out there help me out here? Did any of you already been through this?

  • Cocoa Core Data - Efficient Related Entities Counts

    - by Gary
    I am working on my first iPhone application and I've hit a wall. I'm trying to develop a 'statistics' page for a three entity relationship. My entities are the following: Department - Name, Address, Building, etc. People - Name, Gender (BOOL), Phone, etc If I have fetched a specific department how do I filter those results and only return people that are Male (Gender == 0)? If I do NSLog(@"%d", [department.people count]); I get the correct number of people in that department so I know I'm in the neighborhood. I know I could re-fetch and modify the predicate each time but with 20+ stats in my app that seems inefficient. Thanks for any advice!

  • Regular Expression Help - Brackets within brackets

    - by adbox
    Hello I'm trying to develop a function that can sort through a string that looks like this: Donny went to the {park|store|{beach with friends|beach alone}} so he could get a breath of freash air. What I intend to do is search the text recursively for {} patterns where there is no { or } inside the {}, so only the innermost sandwiched text is selected, where I will then run a php to array the contents and select one at random, repeating process until the whole string has been parsed, showing a complete sentence. I just cannot wrap my head around regular expressions though. Appreciate any help!

  • How can I do an SSL connection with PHP

    - by Anth0
    Hi, I need to develop a PHP class to communicate with Apple servers in order to do Push notification (APNS). I have the certificate (.pem) and I tried to follow various tutorials found on Internet but I'm still getting error trying to connect to ssl://gateway.sandbox.push.apple.com:2195 with stream socket : $apnsHost = 'gateway.sandbox.push.apple.com'; $apnsPort = 2195; $apnsCert = 'apns-dev.pem'; $streamContext = stream_context_create(); stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert); $apns = stream_socket_client('ssl://'.$apnsHost.':'.$apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext); A telnet on this URL works so port 2195 is opened. Openssl is activated on PHP since I get "Registered Stream Socket Transports : tcp, udp, ssl, sslv3, sslv2, tls" with a phpinfo(). My certificate is well read (PHP is_readable(certif.pem) returns true on the file) Is there anything else to activate in Apache or PHP to get it work ?

  • PHP photo gallery with multiple upload form

    - by NightMICU
    Hi everyone, I am trying to develop a PHP driven gallery with a form that has at least four file upload boxes, each with its own title and caption. I have been using php.upload.class to process uploaded photos but not sure how I would go about handling each individual upload while preserving its details (title, caption). Is there a practical way to do this or should I instead upload just the photos and then have the user add titles and captions on the next page? Any help/suggestion would be greatly appreciated. Thanks!

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • Framework/App for custom maps(not general google maps)

    - by Franz Xaver
    Hi! I've started to develop in Android 2 weeks ago and until now, I like it! Currently I am working on a project where I have to display an individual map (not a google maps view, I'd like to display the map of a building's interior) with which the user can interact(mark positions, etc.). Is there a framework or an existing app that I could use? Of course I searched the internet but could not find anything. Perhaps it is in some way possible to use the google maps API? I hope you can help me, thanks in advance!

  • Architectural decision : QT or Eclipse Platform ?

    - by umanga
    We are in the process of designing a tool to be used with HDEM(High Definition Electron Microscope).We get stacks of 2D images from HDEM and first step is 'detecting borders' on the sections.After detecting edges of 2D slices ,next step is construct the 3D model using these 2D slices. This 'border detecting' algorithm(s) is/are implemented by one of professor and he has used and suggests to use C.(to gain high performance and probably will parallelise in future) We have to develop comprehensive UI ,3D viewer ,2D editor...etc and use this algorithm. Application should support usual features like project save/open.Undo,Redo...etc Our technology decisions are: A) Build entire platform from the scratch using QT. B) Use Eclipse Platform Our concerns are, if we choose A) we can easily integrate the 'border detecting' algorithm(s) because the development environment is C/C++ But we have to implement the basic features from the scratch. If we choose B) we get basic features from the Eclipse platform , but integrating C libraries going to be a tedious task. Any suggestions on this?

  • creating a color coded time chart using colorbar and colormaps in python

    - by Rusty
    I'm trying to make a time tracking chart based on a daily time tracking file that I used. I wrote code that crawls through my files and generates a few lists. endTimes is a list of times that a particular activity ends in minutes going from 0 at midnight the first day of the month to however many minutes are in a month. labels is a list of labels for the times listed in endTimes. It is one shorter than endtimes since the trackers don't have any data about before 0 minute. Most labels are repeats. categories contains every unique value of labels in order of how well I regard that time. I want to create a colorbar or a stack of colorbars (1 for eachday) that will depict how I spend my time for a month and put a color associated with each label. Each value in categories will have a color associated. More blue for more good. More red for more bad. It is already in order for the jet colormap to be right, but I need to get desecrate color values evenly spaced out for each value in categories. Then I figure the next step would be to convert that to a listed colormap to use for the colorbar based on how the labels associated with the categories. I think this is the right way to do it, but I am not sure. I am not sure how to associate the labels with color values. Here is the last part of my code so far. I found one function to make a discrete colormaps. It does, but it isn't what I am looking for and I am not sure what is happening.

  • Best architecture for accessing secondary database

    - by fearofawhackplanet
    I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develop a suite of web services against the contacts database 2) Write a Linq to SQL (or EF) DAL and API against the contacts database I will probably be developing several further apps in the future which will also need access to the Contacts data. Which would generally be the prefered method? What are the points I need to consider? Am I even asking a sensible question, or am I missing something obvious?

  • T SQL WHERE Clause

    - by johniom
    Hiya Guys, I'm trying to develop some code which pulls latest informtion only. What it is when a user goes into a form there a subtable and everytime they change something it creates a new row in the colum called type12_OriginalNoteID which puts its own unquie number in. Another feild called type12_OriginalNoteID keeps the same number - which keeps track of what the oringal number was before any changes were made. I do have some code which does pull the latest information but it does not pull anything if the user has not made any changes to the form - and thats because the type12_OriginalNoteID is null. The code is as follows ea.type12_NoteID IN (SELECT TOP 1 ea.type12_NoteID FROM UserAssessv1aidsadaptations ea1 WHERE ea.type12_NoteID = ea1.type12_OriginalNoteID ORDER BY ea.type12_UpdatedDate DESC) An example of the data is as follows :- type12_note ID - 12 type12_OriginalNoteID NULL type12_UpdatedDate - 11/03/2010 What would be the solution to show the ifnroamtion if no one has made any changes to the subtable? - adding an if statement to run if type12_OriginalNoteID is null??

  • How Manage Big Linq DataContext ?

    - by Rev
    Hi The major problem in .net programs is "How manage memory for best performance". so Microsoft use garbage collector in .net and with that, we don't need to do something for managing memory(or better say we can use GC easily) But when you develop big project(business app), you make too many tables and database for your own project. so if you use Linq-to-sql, we must build DataContext include hundred or more tables. That make problem for program when you create an object from datacontext, that object give big amount of memory. also we cant divide datacontext to datacontexts(cuz relation between tables) so "How manage datacontext and memory"?

  • how start implement MVVM pattern

    - by netmajor
    Hello, So i decide to to develop my asp.net site into Silverlight. I today start to search articles about MVVM pattern which i want use in my Silverlight app, and i am confused :/ It's hart to me understand how works this pattern. I am find 3 frameworks which supports MVVM pattern in Silverlight - Caliburn, MVVM Light Toolkit and GoodLight. Should i start from own implementation of pattern or use framework? Is this frameworks only a project solutions in which i can insert my code? Which framework is the best for novice and which for professional? I ask for this, cause i must start to rewrite my app from asp.net to Silverlight and i don't know that i can do it first and later (when i understand MVVM pattern and framework) implement this pattern in finished app ? Or from begining rewrite project to MVVM framework?

  • Is it faster to do the pages first and CSS second, or should I do them at the same time?

    - by Fred Haslam
    I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

  • What is a good Java web crawler library?

    - by DrDee
    Hi, I am about to develop a crawler in Java but don't feel like reinventing the wheel. A quick Google search gives a whole bunch of Java libraries to build a web crawler. Besides that Nutch is of course a very robust package but seems a bit too advanced for my needs. I only need to crawl a handful websites a week containing a couple of 1000 pages each. Which open source Java library would you recommend considering: speed multithreading (or even distributed) extending it with new functionality active maintained and documentation?

  • Oracle XE as local recovery database and Oracle Standard as main db

    - by jbendahan
    Hi, I just wanted to know what you guys think about this. I have an app written in Visual Basic .Net as my front end and and Oracle 11g Standart database as the back-end. So I have like 20 pc's running this app locally. They're all inserting, updating, deleting data on this single database. I want to develop a solution in the case that the server database crashes or cannot stay on line. So i think of having oracle 10g XE on each pc. Thus all the data will be stored in the local db. I think about running a proccess once in a while (ex. every 15 minutes) to send/get the data to/from the main server. What do you think about this strategy?

  • Is there any graphics library in a higher level than OpenGL

    - by Turtle
    Hello, I am looking for a graphics library for 3D reconstruction research to develop my specific viewer based on some library. OpenGL seems in a low level and I have to remake the wheel everywhere. And I also tried VTK(visualization toolkit). However, it seems too abstract that I need to master many conceptions before I start. Is there any other graphics library? I prefer to program in python. So I would like the library has a python wrapper. I think something like O3D would be better. But O3D is for javascript and it seems that Google already stops the development.

  • Class to manage e-mail from iPhone

    - by Scott Pendleton
    I'm working on an iPhone app that offers the user the opportunity to send an e-mail in 3 different places in the app, and for 3 different purposes. Rather than put the same code for showing the e-mail composer in 3 different view controllers, shouldn't I develop a separate E-mail class, create an instance, and then set properties such as To, CC, BCC, Body, HTML_Or_Not, and so on? Also, if I create an instance of such a class, and it brings up the e-mail composer, is it OK to release the class even before the e-mail composer has left the screen?
