• USE case to Class Diagram - How do I?

  - by 01010011

  Hi, I would like your guidance on how to create classes and their relationships (generalization, association, aggregation and composition) accurately from my USE case diagram (please see below). I am trying to create this class diagram so I can use it to create a simple online PHP application that allows the user to register an account, login and logout, and store, search and retrieve data from a MySQL database. Are my classes correct? Or should I create more classes? And if so, what classes are missing? What relationships should I use when connecting the register, login, logout, search_database and add_to_database to the users? I'm new to design patterns and UML class diagrams but from my understanding, the association relationship relates one object with another object; the aggregation relationship is a special kind of association that allows "a part" to belong to more than one "whole" (e.g. a credit card and its PIN - the PIN class can also be used in a debit card class); and a composition relationship is a special form of aggregation that allows each part to belong to only one whole at a time. I feel like I have left out some classes or something because I just can't seem to find the relationships from my understanding of relationships. Any assistance will be really appreciated. Thanks in advance. USE CASE DIAGRAM CLASS DIAGRAM

• ASP.NET MVC - Entending the Authorize Attribute

  - by Mad Halfling

  Hi folks, currently I use [Authorize(Roles = ".....")] to secure my controller actions on my ASP.NET MVC 1 app, and this works fine. However, certain search views need to have buttons that route to these actions that need to be enabled/disabled based on the record selected on the search list, and also the security privs of the user logged in. Therefore I think I need to have a class accessing a DB table which cross-references these target controller/actions with application roles to determine the state of these buttons. This will, obviously, make things messy as privs will need to be maintained in 2 places - in that class/DB table and also on the controller actions (plus, if I want to change the access to the action I will have to change the code and compile rather than just change a DB table entry). Ideally I would like to extend the [Authorize] functionality so that instead of having to specify the roles in the [Authorize] code, it will query the security class based on the user, controller and action and that will then return a boolean allowing or denying access. Are there any good articles on this - I can't imagine it's an unusual thing to want to do, but I seem to be struggling to find anything on how to do it (could be Monday-morning brain). I've started some code doing this, looking at article http://schotime.net/blog/index.php/2009/02/17/custom-authorization-with-aspnet-mvc/ , and it seems to be starting off ok but I can't find the "correct" way to get the calling controller and action values from the httpContext - I could possibly fudge a bit of code to extract them from the request url, but that doesn't seem right to me and I'd rather do it properly. Cheers MH

• tmux: Suddenly, cannot horizontally split

  - by A__A__0

  As root, using a reasonably default .profile and .shrc and an empty tmux.conf, I am unable to split the window horizontally. There are a number of cases to consider so I'll list them clearly. Using the keybinding + empty configuration: nothing happens Using the keybinding + my configuration: a bell is generated, nothing else; occasionally, the split will appear and disappear immediately (maybe it always does this, but I'm connecting over ssh so it may not make it through) Using tmux split-window -h with any config: tmux immediately exits I've posted here in order the server and client verbose logs generated by tmux -v during the third case: server started, pid 9523 socket path /tmp/tmux-0/default new client 7 got 100 from client 7 got 101 from client 7 got 102 from client 7

Occasionally (twice out of the 50 or so times I've tested it), the splitting will work fine once in a session. (This happened for example when I ran ktrace on tmux, which I can also post) To explain the 'suddenly' part of the title: when I started my newly updated mysql56-server, tmux immediately exited and lost the session. Recently I changed architectures, from FreeBSD 10.0 i386 to amd64, and I am still working through shared library incompatibilities. I suspect that this could be involved, but I can't imagine how an incompatibility of this sort could result in such a specific, isolated failure.

• Styling an Input Field

  - by John

  Hello, How can I give the input field below the characteristics listed below? Characteristics: -Text typed into the field starts in the upper left corner and starts on another line (wraps?) when the right border of the field is reached. -A scroll bar appears if the text is more than what can fit into the field. -The text is in Courier font. Thanks in advance, John echo '<form action="http://www...com/sandbox/comments/comments2.php" method="post"> <input type="hidden" value="'.$_SESSION['loginid'].'" name="uid"> <input type="hidden" value="'.$submissionid.'" name="submissionid"> <input type="hidden" value="'.$submission.'" name="submission"> <label class="addacomment" for="title">Add a comment:</label> <input class="commentsubfield" name="comment" type="comment" id="comment" maxlength="1000"> <div class="commentsubbutton"><input name="submit" type="submit" value="Submit"></div> </form> '; Some relevant CSS: .commentsubfield {margin-left: 30px; margin-top: 30px; width: 390px; height: 90px; border: 1px solid #999999; padding: 5px; }

• Android HttpPost: how to get the result

  I have been trying long to send an HttpPost request and retrieve response but even though I was able to make a connection I don't yet get how to get the string message which is returned by the request-response HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://www.myurl.com/app/page.php"); // Add your data List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(5); nameValuePairs.add(new BasicNameValuePair("type", "20")); nameValuePairs.add(new BasicNameValuePair("mob", "919895865899")); nameValuePairs.add(new BasicNameValuePair("pack", "0")); nameValuePairs.add(new BasicNameValuePair("exchk", "1")); try { httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); Log.d("myapp", "works till here. 2"); try { HttpResponse response = httpclient.execute(httppost); Log.d("myapp", "response " + response.getEntity()); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } I'm sorry, I sound very naive because I'm new to java.

• jQuery set selected value in option box once the box has been loaded

  - by Maarten

  I want to preset the value of a selectbox based on a hidden field. I need this after an error has been detected in a form to avoid the user having to set the value themselves again. I do this by setting the value of a hidden field server side. The problem I have seems to be that the select box isn't done yet at the time I try to set the selected value. Anyone know how to solve this (possibly in a very different way?) <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" charset="utf-8"> $(function(){ // this functions loads the state select box with states if a country with states is selected $("select#countries").change(function(){ $.getJSON("/ajax/exhibition/getstates.php?idCountry="+$("select#countries").val(), function(j){ var options = ''; $.each(j, function(key, value){ options += '<option value="' + key + '">' + value + '</option>'; }); $("select#state").html(options); }); }); }); $(document).ready(function(){ // preset the state select box on page ready $('select#countries').change(); // set the selected value of the state select box var foo = $('#statepreset').val(); $("select#state option[value="+foo+"]").attr('selected', 'selected'); }); </script>

• What's with the love of dynamic Languages

  - by Kibbee

  It seems that everybody is jumping on the dynamic, non-compiled bandwagon lately. I've mostly only worked in compiled, static typed languages (C, Java, .Net). The experience I have with dynamic languages is stuff like ASP (Vb Script), JavaScript, and PHP. Using these technologies has left a bad taste in my mouth when thinking about dynamic languages. Things that usually would have been caught by the compiler such as misspelled variable names and assigning an value of the wrong type to a variable don't occur until runtime. And even then, you may not notice an error, as it just creates a new variable, and assigns some default value. I've also never seen intellisense work well in a dynamic language, since, well, variables don't have any explicit type. What I want to know is, what people find so appealing about dynamic languages? What are the main advantages in terms of things that dynamic languages allow you to do that can't be done, or are difficult to do in compiled languages. It seems to me that we decided a long time ago, that things like uncompiled asp pages throwing runtime exceptions was a bad idea. Why is there is a resurgence of this type of code? And why does it seem to me at least, that Ruby on Rails doesn't really look like anything you couldn't have done with ASP 10 years ago?

• Click event keeps firing

  - by Ben Shelock

  I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

• Can't Get Virtual Users Setup in VSFTPD -Tried Everything

  - by N.T.

  Have Ubuntu 11.10 with vsftpd installed and working. Can not get virtual users setup at all? Vsftpd will allow main Ubuntu owner account to login, but nothing else? I've followed several tutorials on adding virtual users, but nothing works? I just need to add 2 virtual users and have them be able to upload files to vsftpd Ubuntu computer from other computers on my Lan network. Everywhere I've looked, people just point toward tutorials on adding virtual users, but that just is NOT working. I've been struggling with this for over a week now! PLEASE Help. Thanks. I'll even give a donation if someone can figure this out. here is the vsftpd.conf file I am using. I copied the original, and make a new one, every time I try a tutorial. So far, none have worked.

• Shared Server Dreamhost

  - by Jseb

  I am trying to install an app on a shared server. If i understand properly because i am using a shared server, and that Dreamhost doesn't suppose rails 3.2.8 I must use FCGI, although i am not sure how to install and to make it run properly. From this tutorial http://wiki.dreamhost.com/Rails_3. To my understand here what I did, In dreamhost, activate PHP 5.x.x FastCGI and made sure Phusion Passenger is unchecked Create an app on my localmachine Because rails doesn't create a dispatch and access file i create the two following file in my /public folder dispatch.fcgi #!/home/username/.rvm/rubies/ruby-1.9.3-p327/bin/ruby ENV['RAILS_ENV'] ||= 'production' ENV['HOME'] ||= `echo ~`.strip ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') ENV['GEM_PATH'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') + ":" + File.expand_path('~/.rvm/gems/ruby 1.9.3-p327@global') require 'fcgi' require File.join(File.dirname(__FILE__), '../config/environment') class Rack::PathInfoRewriter def initialize(app) @app = app end def call(env) env.delete('SCRIPT_NAME') parts = env['REQUEST_URI'].split('?') env['PATH_INFO'] = parts[0] env['QUERY_STRING'] = parts[1].to_s @app.call(env) end end Then created the file .htaccess <IfModule mod_fastcgi.c> AddHandler fastcgi-script .fcgi </IfModule> <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi </IfModule> Options +FollowSymLinks +ExecCGI RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ dispatch.fcgi/$1 [QSA,L] ErrorDocument 500 "Rails application failed to start properly" Uploaded to a folder and pointed to the public folder in dreamhost Made sure dispatch.fcgi has 777 for write ssh and run the following command in the public folder : ./dispatch.fcgi Crossing my finger but it doesn't work I get the following errors ./dispatch.fcgi: line 1: ENV[RAILS_ENV]: command not found ./dispatch.fcgi: line 1: =: command not found ./dispatch.fcgi: line 2: ENV[HOME]: command not found ./dispatch.fcgi: line 2: =: command not found ./dispatch.fcgi: line 3: syntax error near unexpected token (' ./dispatch.fcgi: line 3:ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327')' Doing wrong???

• C# file write permission issue under "Program Files" folder

  - by George2

  Hello everyone, I am using inno setup to make a installation package for my application, and my application is written by C# + .Net 2.0 + VSTS 2008. Inno setup = http://www.jrsoftware.org/isinfo.php and I install my application under Program Files/Foo folder (Foo is my application name). My application is targeting to Windows Vista. The issue I found is my program cannot write to the folder Program Files/Foo. And I need the permission of write to this folder in order to save some configuration files. The strange thing I notice is the folder Program Files/Foo is marked as readonly and I have checked all folders under Program Files are marked with read only, such as Office. My questions are, Why all folders are marked as read only under Program Files? It means we should not write to individual application folders under Program Files? If not, where should we write information to disk like user last selected configuration information of an individual application? If we could write to individual application folders under Program Files, what is the solution? I do not want my application to Run As administrator to solve this issue, and if there are solution to write to this folder, I want to require minimal permission if possible. thanks in advance, George

• Setting Access-Control-Allow-Origin in Dreamhost possible?

  - by Kaushik Gopal

  Just wanted a confirmation for this: Firefox currently doesn't play well for picking custom fonts through a sub-domain via the font-face tag. Other browsers do this without any problems. A little research showed up saying that i am required to set the Access-Control-Allow-Origin as is shown in the link here: http://pastie.org/653265 Essentially i have my blog at kaushikgopal.com/blog and i was trying to access fonts that within this blog that are available at font.kaushikgopal.com. I tried changing the same in my .htaccess file but couldn't resolve the issue.(I placed a .htaccess file within the font sub-domain folder and directly pasted code from the above pastie link). I submitted a ticket to dreamhost asking for assistance and they were helpful in clearly stating "We do not support Access-Control-Allow-Origin on shared hosting servers". So i didn't go the sub-domain route for fonts. But i'm a little curious, has anyone tried this (with a dreamhost hosting account would be helpful)? Just want to confirm what the tech-support guy suggested is accurate and there's no other way. Thanks. Another nice link clearly stating the problem : http://www.stevesouders.com/tests/font-face/xdomain.php

• Can I embed a custom font in an iPhone application?

  - by Airsource Ltd

  I would like to have an app include a custom font for rendering text, load it, and then use it with standard UIKit elements like UILabel. Is this possible? I found these links: http://discussions.apple.com/thread.jspa?messageID=8304744 http://forums.macrumors.com/showthread.php?t=569311 but these would require me to render each glyph myself, which is a bit too much like hard work, especially for multi-line text. I've also found posts that say straight out that it's not possible, but without justification, so I'm looking for a definitive answer. EDIT - failed -[UIFont fontWithName:size:] experiment I downloaded Harrowprint.tff (downloaded from here) and added it to my Resources directory and to the project. I then tried this code: UIFont* font = [UIFont fontWithName:@"Harrowprint" size:20]; which resulted in an exception being thrown. Looking at the TTF file in Finder confirmed that the font name was Harrowprint. EDIT - there have been a number of replies so far which tell me to read the documentation on X or Y. I've experimented extensively with all of these, and got nowhere. In one case, X turned out to be relevant only on OS X, not on iPhone. Consequently I am setting a bounty for this question, and I will award the bounty to the first person who provides an answer (using only documented APIs) who responds with sufficient information to get this working on the device. Working on the simulator too would be a bonus. EDIT - it appears that the bounty auto-awards to the answer with the highest nunber of votes. Interesting. No one actually provided an answer that solved the question as asked - the solution that involves coding your own UILabel subclass doesn't support word-wrap, which is an essential feature for me - though I guess I could extend it to do so.

• Nested URLs and Rewrite rules in Apache2

  - by Radha Krishna. S.

  Hi, I need some help with rewrite rules and nested URLs. I am using TikiWiki for my website and am in the process of setting up SE friendly URLs for my projects. Specifically, I have the following rewrite rule for www.example.com/projects to point to a page that lists out all the projects hosted in example. RewriteRule ^Projects$ articles?type=Project [L] This works fine. Now, I would like to point www.example.com/projects/project1 to point to a specific project. I have this rewrite rule RewriteRule ^(Projects/Project1)$ tiki-read_article.php?articleId=6 This works, but partially. The content is all rendered as text but the theme - images/ css etc all go for a toss - the page is completely in text. I understand that this happens 'cause the relative paths in the theme/ css/ images all refer to Projects as the base folder instead of the root of the website. I don't want to touch the CMS portion - change the theme/ css/ image paths in the files, more for reasons of upgradability. Can someone help me understand and write a rule so that the above nested URL works? Regards, Radha

• REST application, Transactions, Cache drop

  - by Julian Davchev

  Hi, I am building REST API in php with memcache layer on top for caching all resources. After some reading experience it turns out it's best when documents are as simple as posible...mainly due to dropping cache sequences. So if there is 'building','room' entities for the 'room' document I would only place the id of the 'building' and not the whole data of it. Then on api client side I would merge data as needed. Problem becomes when I need to update/insert (most cases more than one table). I update one resource but on second update system fails or whatever and there becomes database inconsistancies. I see several solutions: 1. Implement rest transactions which I find wrong and complex as idea is to be stateless and easy. 2. On update/insert actions I pass more complex data (not single entities) so I can force transactions on API level. But this will make it weird that your GET document structure is same as PUT document structure. And again somehow make drop sequences complex. Any pointers are more than welcome. Cheers,

• Why is Available Physical Memory (dwAvailPhys) > Available Virtual Memory (dwAvailVirtual) in call G

  - by Andrew

  I am playing with an MSDN sample to do memory stress testing (see: http://msdn.microsoft.com/en-us/magazine/cc163613.aspx) and an extension of that tool that specifically eats physical memory (see http://www.donationcoder.com/Forums/bb/index.php?topic=14895.0;prev_next=next). I am obviously confused though on the differences between Virtual and Physical Memory. I thought each process has 2 GB of virtual memory (although I also read 1.5 GB because of "overhead". My understanding was that some/all/none of this virtual memory could be physical memory, and the amount of physical memory used by a process could change over time (memory could be swapped out to disc, etc.)I further thought that, in general, when you allocate memory, the operating system could use physical memory or virtual memory. From this, I conclude that dwAvailVirtual should always be equal to or greater than dwAvailPhys in the call GlobalMemoryStatus. However, I often (always?) see the opposite. What am I missing. I apologize in advance if my question is not well formed. I'm still trying to get my head around the whole memory management system in Windows. Tutorials/Explanations/Book recs are most welcome!

• rails + sheevaplug = rails home development server and more

  - by microspino

  Hello I'd like to build a "Rails Brick" using a Sheevaplug from Marvell (O.S. is Ubuntu out of the box but You can install other distributions on It). It will be a home server and a silent, low cost (99$) low energy development machine. I'd like to add rails RVM, lot of gems, git-based heroku like deployment, passenger + nginx. This way I could have a portable server with a complete development environment and maybe I could find a hosting company where I can co-locate a grid of this devices or I can sell It as a simple little server for 10 or less users offices, with some centralized rails services (I think to a CMS, a BLOG, a WIKI, calendar or whatever this little jewel could afford). The usb port could make It a print server too or a UMTS link to the web via HUAWEI like usb UMTS keys. Can you give me some hint about: Is this project a crazy-close-to-failure idea? Why? which gem would You include? which rails open source app would you suggest? I have already an Excito Bubba Server at home, I saw the TonidoPlug so It came up in my mind to build something similiar but Rails based (Bubba is PHP based, TonidoPlug I don't know but It does not seems a Rails thing).

• jQuery: Traversing AJAX response in Chrome/Safari

  - by jitzo

  I'm trying to traverse an AJAX response, which contains a remote web page (an HTML output). My goal is to iterate through the 'script', 'link', and 'title' elements of the remote page - load them if necessary, and embed its contents to the current page. Its working great in FF/IE, but for some reason - Chrome & Safari behaves differently: When I run a .each() loop on the response, Chrome/Safari seems to omit everything that is under the section of the page. Here's my current code: $.ajax({ url: 'remoteFile.php', cache: false, dataFilter: function(data) { console.log(data); /* The output seems to contain the entire response, including the <head> section - on all browsers, including Chrome/Safari */ $(data).filter("link, script, title").each(function(i) { console.log($(this)); /* IE/FF outputs all of the link/script/title elements, Chrome will output only those that are not in the <head> section */ }); console.log($(data)); /* This also outputs the incomplete structure on Chrome/Safari */ return data; }, success: function(response) {} }); I've been struggling with this problem for quite a while now, i've found some other similar cases on google searches, but no real solution. This happens on both jQuery 1.4.2, and jQuery 1.3.2. I really don't want to parse the response with .indexOf() and .substring() - it seems to me that it will be an overkill for the client. Many thanks in advance!

• What are the best open-source software non-profits for making financial contributions and/or facilitating useful work?

  - by Jason S

  I'm not a great programmer myself (my main job is more electrical engineering) and have never really helped out with any open source projects, but I've benefited greatly from free and/or open-source software (MySQL, OpenOffice, Firefox, Apache, PHP, Java, etc.) and at some point would like to make some modest financial contributions to help keep this stuff going. I'm wondering, what are the best non-profits to make financial contributions? I'm aware of: Open Source Initiative (founded 10 years ago by several prominent figures including programmer and "The Cathedral and the Bazaar" author Eric S. Raymond) Free Software Foundation Mozilla Foundation Apache Foundation Anyone have a particular favorite? Ideally I'd like to give money to a non-profit that would foster some of the smaller but promising open-source and/or free software projects. The big projects like Firefox and Apache are already well-established. There are a few small individual shareware programs I've already paid for directly. But it's those middle-ground projects that I would really like my contributions to support. (one that comes to mind is a good GUI for Subversion or Mercurial.) It's one thing for a single person to donate a little $$ to a small project. It's another for a foundation or something to give larger grants to projects that give a good bang for the buck. Conservation organizations like The Nature Conservancy, or the Trust for Public Lands, have really honed this approach, but I'm not really sure if there's an equivalent model in software-land.

• Insert video clip in a lyx presentation and play it in GNU/Linux.

  - by Orjanp

  How can I insert a video clip into a presentation created in Lyx? Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player. I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer. Beamer is used as a presentation template. Is it possible to play a video file in an embedded player in the presentation itself? Created an example presentation.

• facebook connect button not producing pop-up

  - by bigmac

  This is a really simple question, but I can't seem to find the answer. I am just getting started with Facebook Connect. I would like to use it only for user authentication, so there is no need for my users to create another account. I used a very basic example from wiki.developers.facebook.com : <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head></head> <body> <fb:login-button></fb:login-button> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript"> FB.init("***api-key***", "xd_receiver.htm"); </script> </body> </html> Very straight forward. It seems to work fine. However, if I am currently already logged in to Facebook, the pop-up window doesn't come up when I click the login button. Why is that?

• How to upload a file with watir and IE?

  - by karlthorwald

  I am writing a watir script to test an upload form. But the script does not automatically choose the file that is to be uploaded from my harddrive. Instead IE stops with the file chooser dialog open. As soon as I manually select the to be uploaded file in the dialog and click ok, watir continues as desired. I wonder why it stops. This is from my watir script: ie.file_field(:name, 'upload').set("s:\\localwatir\\Test_Pdf.pdf") ie.button(:name, 'submit').click I got the code from this page: http://wiki.openqa.org/display/WTR/File+Uploads This is the form: <form name="form1" enctype="multipart/form-data" method="post" action="uploadlegacy.php"> <input type="file" name="upload" size="30"> <input type="submit" name="submit" value="upload"> </form> I have found this manual http://svn.openqa.org/svn/watir/trunk/watir/unittests/filefield_test.rb also, but as I do not know what $htmlRoot stands for, I cannot really follow it. Does that mean, I have to put some "file///" into the parameter for set()? If so, how exactly? I am using IE 6 for the testing.
