  • Artists and music - Need Help Deciding on a CMS

    - by infty
    A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own smaller gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implemented all of these features, but I want to use an existing content management system for all of these features so that future developers can, hopefully, more easy extend the website. And also, so that I don't have to provide too much documentation. I have never developed a website using an external CMS like Drupal or Wordpress and after seeing hours of tutorial videos of both systems, I still can't make up my mind on whether i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can imagine that staff members would also want to create content using iPhone or android based mobile devices, but this is not a required feature. Can someone, with experience, please tell me about their experiences with larger projects like this? The site will have approximately 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

  • What makes you look like a bad developer (ie a hacker) [on hold]

    - by user134583
    This comes from a lot of people about me, so I have to look at myself. So I would wonder what make one a bad developer (ie a hacker). These are a few things about me I used IDE intensively, all features, you name it: auto-completion, refactoring, quick fixes, open type, view hierarchy, API documentation, etcc When I deal with writing code for a project in domain I am not used to (I can't have fluency in this, this is new), I only have a very rough high level ideas. I don't use the standard modeling diagrams for early detail planning. Unorthodox diagrams that I invented when I need to draw the design in details. I don't use UML or similar, I find them not enough. I divide the sorts of diagram I drew into 3 types. Very high level diagrams which probably can be understood by almost anybody. Data entity diagram used for modeling data objects only (like ER diagrams and tree for inheritances and composition). Action diagrams for agents/classes and their interactions on data objects they contain. Constantly changing the interface (public methods) between interacting agents/classes if the need arises. I am more refrained when the interface and the module have matured Write initial concept code in a quick hackie way just so that the module works in the general cases so that I can play around with it. The module will be re-factored intensively after playing around so I could see more corner cases that I couldn't or (wouldn't want) anticipate before writing code. Using JUnit for integration-like test by using TestSuite class and ordering Unit test classes in the suite Using debugger almost anytime there is a problem instead of reading the code Constantly search on the internet for how to do some thing with some library that I haven't used a lot. So judgment, am I a bad developer? a hacker? Put in other words, to make sure this is not considered off-topic: - Is this bad practice to make your code too agile during incubating/prototyping phase of software development - Is it bad practice to use JUnit for integration testing, (I know there are other framework for integration testing, but those frameworks are for a specific products, not general)

  • Can you recommend a game server for a facebook board game?

    - by Yekmer Simsek
    I am seeking a game server that will scale well. All commercial and/or free software alternatives are welcome. Game will be a boardgame that is similar to poker. Some technical details are listed below. There will be a table which consists of 4 people, to send them message I need a channel manager. A table will be ready to play for at least 5 minutes. There should be a reliable channel manager. People will wait for some time(i.e.) and if they are not playing they will be kicked by server, so there will be a reliable timed task queue to execute some tasks. It should be quick enough to response and show the changes to all 4 people on that table simultaneously.To achive this server should have a powerfull I/O library. I think to use inmemory to have quick response times, but it comes with scalability problems. And some variables should be thread safe so a variable should be thread safe between multiple nodes. Flash(AS3) and Unity (.Net 2.0 C# mono) client API's should be available for socket connection. PS: I am using Reddwarf server, it lacks of documentation and multiple node.

  • Will buy simple Cocos2D bubbles iPad game for private use (source)

    - by boliva
    Hi, First of all, sorry if this is the wrong place for posting this kind of request. IDK if is there already a marketplace on the stack community. I'm a fairly experienced iPhone/iPad developer with several Apps already published. I have a deep understanding of Objective-C and the Cocoa framework, as well as with the iPhone development tools. However, I have never used Cocos2d (or any other gaming engine for that matter) as I've mostly specialized in utilities/productivity Apps. I am in the urgent need of developing a really simple iPad game (for which I will provide all of the media assets - graphics and sounds) that needs to be deployed in about a week from now. Basically the game should allow the user to pop bubbles of different size and speed as they move from the bottom to the top of the screen. While I could take the time to read the documentation and start working on this game myself, I'm currently with a couple of other projects that I need to finish soon, so I would like to ask for the help of some other more experienced Cocos2D developer which could develop this game on its basic form for me. If you think you can help, please send me your quote, timing and, if possible, samples of previous work done with Cocos2D that would be similar to what I need. I can provide more detail upon request. Best and thank you all.

  • &ldquo;Why do transactional messages all have the same priority?&rdquo;

    - by John Breakwell
    I answered this question on the MSMQ forum on MSDN and thought it worth sharing here. The poster wanted to know why all transactional messages have a fixed priority of zero (instead of 0 through 7). They wanted the guaranteed delivery of messages to a queue but wanted to assign different levels of priority. Some aspects of MSMQ were defined way back in the last century and this is one of them. If I remember right, the reason was to avoid the following scenario: You have a single transaction of 3 messages (a, b and c) with priorities 5, 3 and 4 respectively. The messages are sent in order a,b,c The messages arrive in the queue and are arranged in order a,c,b to reflect priority order This breaks the guaranteed order part of the transaction.  I know that very few people send more than one message in a transaction but that is a scenario that MSMQ has to be able to handle; for the majority, including yourself, this scenario is irrelevant which is why you are surprised by the absence of transactional priorities. The options, therefore, available to the Microsoft developers were to: Implement code that allowed you to send messages with variable priority as long as any messages within the same transaction were the same priority, or Define a set priority for all transactional messages As you can understand, option 1 would be a complicated arrangement with all the necessary enforcement, error handling, user education and documentation, etc. Sure, it would have been possible to implement option 1 but I expect the product group decided to invest the development time in some other aspect of MSMQ. Now, with five versions out there, it would be confusing to change how the product operates, in addition to potentially breaking exisiting systems that have been working fine for years. So, balancing cost and risk against customer demand, I would not expect this feature to ever change.

  • Creating my own PHP framework

    - by onlineapplab.com
    Disclaimer: I don't want to start any flame war so there will not be no name of any framework mentioned. I've been using quite many from the existing PHP frameworks and my experience in each case was similar: everything is nice a the beginning but in the moment you require something non standard you get into lot of problems to fix otherwise simple issues. In case of frameworks following the MVC design pattern there are some issues with the implementation of each layer for example there is a lot of codding used for model and data access with using ORM and presentation is not much more than pure phtml. Some frameworks use their own wrappers for existing PHP functionality and in some cases severely limiting original functionality. Depending on framework you can have additional problems like lack of documentation, slow or non existent development cycle and last but not least speed. While ago I made my own framework which while doing it's job and being used for few different applications after couple of years more of experience with PHP doesn't seem to be perfect piece of codding. I could write my own framework and use additional experience I've gathered during these years to make it better on the other hand I'm aware that there is quite many better programmers working on creating/upgrading existing frameworks. So does it make at all nay sense to write my own PHP framework if there is so many possibilities to choose from?

  • Why using Fragments?

    - by ahmed_khan_89
    I have read the documentation and some other questions' threads about this topic and I don't really feel convinced; I don't see clearly the limits of use of this technique. Fragments are now seen as a Best Practice; every Activity should be basically a support for one or more Fragments and not call a layout directly. Fragments are created in order to: allow the Activity to use many fragments, to change between them, to reuse these units... == the Fragment is totally dependent to the Context of an activity , so if I need something generic that I can reuse and handle in many Activities, I can create my own custom layouts or Views ... I will not care about this additional Complexity Developing Layer that fragments would add. a better handling to different resolution == OK for tablets/phones in case of long process that we can show two (or more) fragments in the same Activity in Tablets, and one by one in phones. But why would I use fragments always ? handling callbacks to navigate between Fragments (i.e: if the user is Logged-in I show a fragment else I show another fragment). === Just try to see how many bugs facebook SDK Log-in have because of this, to understand that it is really (?) ... considering that an Android Application is based on Activities... Adding another life cycles in the Activity would be better to design an Application... I mean the modules, the scenarios, the data management and the connectivity would be better designed, in that way. === This is an answer of someone who's used to see the Android SDK and Android Framework with a Fragments vision. I don't think it's wrong, but I am not sure it will give good results... And it is really abstract... ==== Why would I complicate my life, coding more, in using them always? else, why is it a best practice if it's just a tool for some cases? what are these cases?

  • Mobile (Client) to Amazon S3 (Server) - Architecture

    - by wasabii
    let's start off with the problem statement: My iOS application has a login form. When the user logs in, a call is made to my API and access granted or denied. If access was granted, I want the user to be able to upload pictures to his account and/or manage them. As storage I've picked Amazon S3, and I figured it'd be a good idea to have one bucket called "myappphotos" for instance, which contains lots of folders. The folder names are hashes of a user's email and a secret key. So, every user has his own, unique folder in my Amazon S3 bucket. Since I've just recently started working with AWS, here's my question: What are the best practices for setting up a system like this? I want the user to be able to upload pictures directly to Amazon S3, but of course I cannot hard-code the access key. So I need my API to somehow talk to Amazon and request an access token of sorts - only for the particular folder that belongs to the user I'm making the request for. Can anyone help me out and/or guide me to some sources where a similar problem was addressed? Don't think I'm the first one and the amazon documentation is so extensive that I don't really know where to start looking. Thanks a lot!

  • One sentence descriptions of the various common software licenses?

    - by Rich
    Instead of having to read entire documentation and sift through all the legalese, can someone outline the more common licenses in language that is short and sweet and gets right to the point? Specifically, I'm using a 3rd party control that uses the Apache 2.0 license. My intention is to use this in a proprietary application that I am building for a corporation's use (not resold, but I'm being paid for my work). Does this mean I can or cannot use this control? Does it mean that I must maintain copyright/license information in my code? Does it mean that I must mention copyright/license information in a clearly visible location in the app? EDIT In response to an answer below with a link to an article by Jeff Atwood, the Apache license is described as follows: Apache License Open Permissive 9 Requires derivative works to provide notification of any licensed or proprietary code in a common location. Does this notification need to be in a "common location" in my source code or a common location visible within the app? What if this were a non GUI app (I'm assuming that could very well be my answer)? Thanks for the responses!!!

  • Should I Open Source? [closed]

    - by Howdy_McGee
    My company recently created a full javascript, html & css Virtual Tour. Since it is html based there is no real way of securing our information/code so selling it could be flimsy. We are an extremely small company, barely on the map so I was thinking that by making this an open source project it could give us a chance to jump start our SEO by page views alone, especially if we provide documentation. Not to mention hopefully bring a community following on our blog. On the other hand though could this possibly hurt our sales as a web development company? If we are handing out this cool "plugin" we made what keeps people from making it commercial somehow? So I'm trying to weigh the options on whether I should make this Open Source or not and the pros / cons of each especially for a small business. What do you guys think about making things Open Source? How do I know if this product is the right thing to make Open Source? What are some pros and cons to going Open Source?

  • Release Notes for 7/6/2012

    Happy belated 4th of July, everyone! Here are the notes for this week’s release on CodePlex: Implemented performance improvements to Git repositories. Fixed an issue that caused the final “click here” download link to fail in projects that display ads. Fixed an issue for certain projects that made it impossible to edit releases. Fixed an issue where the URL for a diff of a file would not take users to the diff in question. Fixed a rare issue that prevented a small subset of projects from modifying their project details. Fixed an issue where scrollbars were missing in our side-by-side diff viewer. Super- and sub-scripts now work properly in documentation. Addressed several usability issues around the diff viewer. Fixed an issue where the scrollbar could disappear in the advanced issue tracker if a user opens a modal dialog. Have ideas on how to improve CodePlex? Visit our ideas page!

  • Is it normal for GRUB to take some time (15+s) after I choose what to boot?

    - by zarnaik
    I had been planning to change the background of my bootloader for a while, and finally got to it. Now the black screen I get for quite some time was made clear. It is still GRUB, because the background image stays, while all of the text is gone. Then it just simply shows the Lubuntu loading screen for, usually, not more than 3 seconds. I run Lubuntu 12.10. My question is, is this normal behaviour or is something going wrong, causing GRUB to take longer? Here are the contents of my grub file located at /etc/default/ : # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND="/usr/share/lubuntu/wallpapers/1210-Windmill_by_Ferran_Reyes.png" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" If you need any other information please tell me and I'll do my best to provide it. :)

  • What is the most effective approach to learn an unfamiliar complex program? [closed]

    - by bdroc
    Possible Duplicate: How do you dive into large code bases? I have quite a bit of experience with different programming languages and writing small and functional programs for a variety of purposes. My coding skills aren't what I have a problem with. In fact, I've written a decent web application from scratch for my startup. However, I have trouble jumping into unfamiliar applications. What's the most effective way to approach learning a new program's structure and/or architecture so that I can start attacking the code effectively? Are there useful tools for their respective languages (Python and Java are my two primary languages)? Should I be starting with just looking at function names or documentation? How do you veterans approach this problem? I find this has to be with minimal help from coworkers or contributors who are already familiar with the application and have better things to do than help me. I'd love to practice this skill in an open source project so any suggestions for starting points (maybe mildly complex) would be great too!

  • Social Network ( Help) [on hold]

    - by brunocascio
    I am in a great "problem" so to speak , and I need opinions to decide. The problem is to create a social network without knowing the number of users who use it (but if thinking if they were sufficient ) . The question is which language and framework to use .... I do not mind having to learn new technologies and / or languages ??. I am among PHP ( Laravel - Symfony - other? ) Ruby ( Ruby on Rails 4? ) Javascript ( Ember , express, locomotive , other? ) Python ( Django ) Java ( Grails , Play, other?) I have experience in both PHP and frameworks. In Symfony developed part of it, but I got tired having to do a thousand configurations for all . I know very little about Ruby , but I saw very easy . I do not know are saying the performance. Javascript costs me to get used to their paradigm , and do not know if at all sure to cover everything with Javascript. Django and python ( very poor knowledge ) Java , experience in data structure and android , but not web . Regarding the / s databases: In my head I have to MongoDB and costs change of opinion by another database with respect to documentation and EASE performance . But .......... frameworks have no support at all clear . I also thought of mixing technologies for using a tecnlogía backend and the frontend other. As I read in the new social network Origo . They use Symfony for REST and javascript for the frontend . ( Backbone , Underscore and RequireJS ) What do you recommend me ?

  • Creating a multi-tenant application using PostgreSQL's schemas and Rails

    - by ramon.tayag
    Stuff I've already figured out I'm learning how to create a multi-tenant application in Rails that serves data from different schemas based on what domain or subdomain is used to view the application. I already have a few concerns answered: How can you get subdomain-fu to work with domains as well? Here's someone that asked the same question which leads you to this blog. What database, and how will it be structured? Here's an excellent talk by Guy Naor, and good question about PostgreSQL and schemas. I already know my schemas will all have the same structure. They will differ in the data they hold. So, how can you run migrations for all schemas? Here's an answer. Those three points cover a lot of the general stuff I need to know. However, in the next steps I seem to have many ways of implementing things. I'm hoping that there's a better, easier way. Finally, to my question When a new user signs up, I can easily create the schema. However, what would be the best and easiest way to load the structure that the rest of the schemas already have? Here are some questions/scenarios that might give you a better idea. Should I pass it on to a shell script that dumps the public schema into a temporary one, and imports it back to my main database (pretty much like what Guy Naor says in his video)? Here's a quick summary/script I got from the helpful #postgres on freenode. While this will probably work, I'm gonna have to do a lot of stuff outside of Rails, which makes me a bit uncomfortable.. which also brings me to the next question. Is there a way to do this straight from Ruby on Rails? Like create a PostgreSQL schema, then just load the Rails database schema (schema.rb - I know, it's confusing) into that PostgreSQL schema. Is there a gem/plugin that has these things already? Methods like "create_pg_schema_and_load_rails_schema(the_new_schema_name)". If there's none, I'll probably work at making one, but I'm doubtful about how well tested it'll be with all the moving parts (especially if I end up using a shell script to create and manage new PostgreSQL schemas). Thanks, and I hope that wasn't too long! UPDATE May 11, 2010 11:26 GMT+8 Since last night I've been able to get a method to work that creates a new schema and loads schema.rb into it. Not sure if what I'm doing is correct (seems to work fine, so far) but it's a step closer at least. If there's a better way please let me know. module SchemaUtils def self.add_schema_to_path(schema) conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{schema}, #{conn.schema_search_path}" end def self.reset_search_path conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{conn.schema_search_path}" end def self.create_and_migrate_schema(schema_name) conn = ActiveRecord::Base.connection schemas = conn.select_values("select * from pg_namespace where nspname != 'information_schema' AND nspname NOT LIKE 'pg%'") if schemas.include?(schema_name) tables = conn.tables Rails.logger.info "#{schema_name} exists already with these tables #{tables.inspect}" else Rails.logger.info "About to create #{schema_name}" conn.execute "create schema #{schema_name}" end # Save the old search path so we can set it back at the end of this method old_search_path = conn.schema_search_path # Tried to set the search path like in the methods above (from Guy Naor) # conn.execute "SET search_path TO #{schema_name}" # But the connection itself seems to remember the old search path. # If set this way, it works. conn.schema_search_path = schema_name # Directly from databases.rake. # In Rails 2.3.5 databases.rake can be found in railties/lib/tasks/databases.rake file = "#{Rails.root}/db/schema.rb" if File.exists?(file) Rails.logger.info "About to load the schema #{file}" load(file) else abort %{#{file} doesn't exist yet. It's possible that you just ran a migration!} end Rails.logger.info "About to set search path back to #{old_search_path}." conn.schema_search_path = old_search_path end end

  • Small performance test on a web service

    - by vtortola
    Hi, I'm trying to develop a small application that test how many requests per second can my service support but I think I'm doing something wrong. The service is in an early development stage, but I'd like to have this test handy in order to check in time to time I'm not doing something that decrease the performance. The problem is that I cannot get the web server or the database server go to the 100% of CPU. I'm using three different computers, in one is the web server (WinSrv Standard 2008 x64 IIS7), in other the database (Win 2K - SQL Server 2005) and the last is my computer (Win7 x64 ultimate), where I'll run the test. The computers are connected through a 100 ethernet switch. The request POST is 9 bytes and the response will be 842 bytes. The test launches several threads, and each thread has a "while" loop, in each loop it creates a WebRequest object, performs a call, increment a common counter and waits between 1 and 5 millisencods, then it do it again: static Int32 counter = 0; static void Main(string[] args) { ServicePointManager.DefaultConnectionLimit = 250; Console.WriteLine("Ready. Press any key..."); Console.ReadKey(); Console.WriteLine("Running..."); String localhost = "localhost"; String linuxmono = "192.168.1.74"; String server= "192.168.1.5:8080"; DateTime start = DateTime.Now; Random r = new Random(DateTime.Now.Millisecond); for (int i = 0; i < 50; i++) { new Thread(new ParameterizedThreadStart(Test)).Start(server); Thread.Sleep(r.Next(1, 3)); } Thread.Sleep(2000); while (true) { Console.WriteLine("Request per second :" + counter/DateTime.Now.Subtract(start).TotalSeconds ); Thread.Sleep(3000); } } public static void Test(Object ip) { Guid guid = Guid.NewGuid(); Random r = new Random(DateTime.Now.Millisecond); while (true) { String test = "<lalala/>"; WebRequest req = WebRequest.Create("http://" + (String)ip + "/WebApp/"+guid.ToString()+"/Data/Tables=whatever"); req.Method = "POST"; req.ContentType = "application/xml"; req.Credentials = new NetworkCredential("aaa", "aaa","domain"); Byte[] array = Encoding.UTF8.GetBytes(test); req.ContentLength = array.Length; using (Stream reqStream = req.GetRequestStream()) { reqStream.Write(array, 0, array.Length); reqStream.Close(); } using (Stream responseStream = req.GetResponse().GetResponseStream()) { String response = new StreamReader(responseStream).ReadToEnd(); if (response.Length != 842) Console.Write(" EEEE "); } Interlocked.Increment(ref counter); Thread.Sleep(r.Next(1,5)); } } If I run the test neither of the computers do an excesive CPU usage. Let's say I get a X requests per second, if I run the console application two times at the same moment, I get X/2 request per second in each one... but still the web server is on 30% of CPU, the database server on 25%... I've tried to remove the thread.sleep in the loop, but it doesn't make a big difference. I'd like to put the machines to the maximun, to check how may requests per second they can provide. I guessed that I could do it in this way... but apparently I'm missing something here... What is the problem? Kind regards.

  • Get information about AutocompleteTextView from resulting AutoCompleteTextView$DropDownListView

    - by Stev_k
    I'm using 3 AutocompleteTextViews to suggest entries from a database. I subclassed AutocompleteTextView to handle setting the default text to null when clicked and setting back to the default instructions if moved away and nothing is entered. I was using a SimpleCursorAdapter to bind to the view, but I discovered that there was no way I could get the id of the AutocompleteTextView from an OnItemClickListener, which I needed to put additional information from the selected row in a variable depending on which AutocompleteTextView it was from. All I could access was the AutoCompleteTextView$DropDownListView, which is an undocumented inner class that appears to offer no real functionality. Neither was there a way to go up the view hierarchy to get the original AutocompleteTextView. So I subclassed SimpleCursorAdapter and added an int to the constructor to identify which AutocompleteTextView the adapter was from, and I was able to access this from the view passed into OnItemClick(). So, although my solution works fine, I wonder if it is possible to get the id of an AutocompleteTextView from its DropDownListView? I am also using another database query which gets the id from the OnItemClick and then looks up the data for that item, because I couldn't find a way of converting more than one column to a string. Should I be using CursorAdapter for this, to save initiating another query? Oh, and another thing, do I need a database cursor initially (all_cursor) when all I'm doing is filtering on it to get a new cursor? Seems like overkill. Activity .... dbse.openDataBase(); Cursor all_Cursor = dbse.autocomplete_query(); startManagingCursor(all_Cursor); String[] from_all = new String[]{DbAdapter.KEY_NAME}; int[] to_all = new int[] {android.R.id.text1}; from_adapt = new AutocompleteAdapter(FROM_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); from_adapt.setStringConversionColumn(1); from_adapt.setFilterQueryProvider(this); to_adapt = new AutocompleteAdapter(TO_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); to_adapt.setStringConversionColumn(1); to_adapt.setFilterQueryProvider(this); from_auto_complete = (Autocomplete) findViewById(R.id.entry_from); from_auto_complete.setAdapter(from_adapt); from_auto_complete.setOnItemClickListener(this); to_auto_complete = (Autocomplete) findViewById(R.id.entry_to); to_auto_complete.setAdapter(to_adapt); to_auto_complete.setOnItemClickListener(this); public void onItemClick (AdapterView<?> parent, View view, int position, long id) { Cursor selected_row_cursor = dbse.data_from_id(id); selected_row_cursor.moveToFirst(); String lat = selected_row_cursor.getString(1); String lon = selected_row_cursor.getString(2); int source = ((AutocompleteAdapter) parent.getAdapter()).getSource(); Autocomplete class: public class Autocomplete extends AutoCompleteTextView implements OnTouchListener,OnFocusChangeListener{ String textcontent; Context mycontext = null; int viewid = this.getId(); public Autocomplete(Context context, AttributeSet attrs) { super(context, attrs); textcontent = this.getText().toString(); mycontext = context; this.setOnFocusChangeListener(this); this.setOnTouchListener(this); } public boolean onTouch(View v, MotionEvent event) { if (textcontent.equals(mycontext.getString(R.string.from_textbox)) | textcontent.equals(mycontext.getString(R.string.to_textbox)) | textcontent.equals(mycontext.getString(R.string.via_textbox))) { this.setText(""); } return false; } public void onFocusChange(View v, boolean hasFocus) { if (hasFocus == false) { int a = this.getText().length(); if (a == 0){ if (viewid == R.id.entry_from) {this.setText(R.string.from_textbox);} if (viewid == R.id.entry_to) {this.setText(R.string.to_textbox);} if (viewid == R.id.entry_via) {this.setText(R.string.via_textbox);} } } } } Adapter: public class AutocompleteAdapter extends SimpleCursorAdapter { int source; public AutocompleteAdapter(int query_source, Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); source = query_source; } public int getSource() { return source; } } sorry that's a lot of code! Thanks for your help. Stephen

If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly The php side of service is <?php // Pull in the NuSOAP code require_once('../../lib/tools/nusoap/nusoap.php'); $ns = "urn:currencywebservice"; // Create the server instance $server = new soap_server(); // Initialize WSDL support $server->configureWSDL('currencywebservice', $ns); $server->xml_encoding = "utf-8"; $server->soap_defencoding = "utf-8"; $server->wsdl->schemaTargetNamespace = $ns; $server->register('GetAllCurrencies', array(), array('return' => 'xsd:string'), $ns, $ns."#GetAllCurrencies", 'rpc', 'literal', 'Get all currencies available'); // Define the method as a PHP function function GetAllCurrencies() { return "test return"; } // Use the request to (try to) invoke the service header('Content-Type: text/xml; charset=utf8'); $server->service($HTTP_RAW_POST_DATA); ?> Please help me out what is this problem?

  • Understanding Node.js and concept of non-blocking I/O

    - by Saif Bechan
    Recently I became interested in using Node.js to tackle some of the parts of my web-application. I love the part that its full JavaScript and its very light weight so no use anymore to call an JavaScript-PHP call but a lighter JavaScript-JavaScript call. I however do not understand all the concepts explained. Basic concepts Now in the presentation for Node.js Ryan Dahl talks about non-blocking IO and why this is the way we need to create our programs. I can understand the theoretical concept. You just don't wait for a response, you go ahead and do other things. You make a callback for the response, and when the response arrives millions of clock-cycles later, you can fire that. If you have not already I recommend to watch this presentation. It is very easy to follow and pretty detailed. There are some nice concepts explained on how to write your code in a good manner. There are also some examples given and I am going to work with the basic example given. Examples The way we do thing now: puts("Enter your name: "); var name = gets(); puts("Name: " + name); Now the problem with this is that the code is halted at line 1. It blocks your code. The way we need to do things according to node puts("Enter your name: "); gets(function (name) { puts("Name: " + name); }); Now with this your program does not halt, because the input is a function within the output. So the programs continues to work without halting. Questions Now the basic question I have is how does this work in real-life situations. I am talking here for the use in web-applications. The application I am writing does I/O, bit is still does it in am blocking matter. I think that most of the time, if not all, you need to block, because you have to wait on what the response is you have to work with. When you need to get some information from the database, most of the time this data needs to be verified before you can further with the code. Example 1 If you take a login for example. You have to wait for the database to response to return, because you can not do anything else. I can't see a way around this without blocking. Example 2 Going back to the basic example. The use just request something from a database which does not need any verification. You still have to block because you don't have anything to do more. I can not come up with a single example where you want to do other things while you wait for the response to return. Possible answers I have read that this frees up recourses. When you program like this it takes less CPU or memory usage. So this non-blocking IO is ONLY meant to free up recourses and does not have any other practical use. Not that this is not a huge plus, freeing up recourses is always good. Yet I fail to see this as a good solution. because in both of the above examples, the program has to wait for the response of the user. Whether this is inside a function, or just inline, in my opinion there is a program that wait for input. Resources I looked at I have looked at some recourses before I posted this question. They talk a lot about the theoretical concept, which is quite clear. Yet i fail to see some real-life examples where this is makes a huge difference.
