• Sunshine after the iCloud release?

  - by Laila

  "Why should I believe them? They're the ones that brought us MobileMe? It was not our finest hour, but we learned a lot." Steve Jobs June 6th 2011 Apple's new cloud service has been met with uncritical excitement by industry commentators.  It is wonderful what a rename can do.  Apple has had a 'cloud' offering for three years called MobileMe, successor to .MAC and  iTools, so iCloud is now the fourth internet service Apple have attempted. If this had been Microsoft, there would have been catcalls all around the blogosphere.  I'll admit that there is a lot more functionality announced for iCloud than MobileMe has ever managed to achieve, but then almost anything has more functionality than MobileMe.  It's an expensive service (£120 a year in the UK, $90 in the states), launched as far back as  June 9, 2008, that has delivered very little and suffered a string of technical problems; the documentation was mainly  a community effort, built up gradually by the frustrated and angry users. It was supposed to synchronise PC Outlook calendars but couldn't manage Microsoft Exchange (Google could, of course). It used WebDAV to allow Windows users to attach to the filestore, but didn't document how to do it. The method for downloading and uploading files to the cloud-based filestore was ridiculously clunky. It allowed you to post photos on a public site, but forgot to include a way of deleting photos. I could go on with the list, but you can explore the many sites that have flourished to inhabit the support-vacuum left by Apple. MobileMe should have had all the bright new clever things announced for iCloud. Apple dropped the ball, and allowed services such as Flickr to fill the void. However, their PR skills are such that, a name-change later (the .ME.com email address remains), it has turned a rout into a victory, and hundreds of earnest bloggers have been extolling Apple's expertise in cloud matters. This must be frustrating for the other cloud providers who have quietly got the technology working right. I wish iCloud well, even though I resent the expensive mess they made of MobileMe. Apple promise that iCloud will sync files, apps, app data, and media across all the different iOS5 devices, Macs, and PCs. It also hopes to sync music across devices, but not video content. They've offered existing MobileMe users free use of the MobileMe service for a year as the product is morphed, and they will be able to transfer to iCloud when it is launched in the autumn.  On June 30, 2012, MobileMe will die, and Apple's iWeb is also soon to join iTools and .MAC in the hereafter. So why get excited about iCloud? That all depends on the level of PC integration. Whereas iOS5 machines will be full participants in the new world of data-sharing (Sorry iPod Touch users) what about .NET libraries? There is talk of synchronising 'My Pictures' libraries with iOS5 and iMac machines, but little more detail as yet. Apple has a lot to prove with iCloud and anyone with actual experience of their past attempts to get into cloud services will be wary.

• Gaming on Cloud

  - by technomad

  Sometimes I wonder the pundits of cloud computing are way to consumed with the enterprise applications. With all the CAPEX / OPEX, ROI-talk taking the center stage, an opportunity to affect masses directly is getting overlooked. I am a self proclaimed die hard gamer. I come from the generation of gamers who started their journey in DOS games like Wolfenstein 3D and Allan Border Cricket (the latter is still a favorite pastime). In the late 90s, a revolution called accelerated graphics started in DirectX and OpenGL. Games got more advanced. Likes of Quake III and Unreal Tournament became the crown jewels of the industry. But with all these advancements, there started a race. A race of GFX giants ATI and NVIDIA to beat each other for better frame and image quality. Revisions to the graphics chipsets became frequent. Games became eye candies but at the cost of more GPU power / memory. Every eagerly awaited title started demanding more muscle power in graphics and PC hardware. Latest games and all the liquid smooth frame rates became the territory of the once with deep pockets who could spend lavishly on latest hardware. Enthusiasts like yours truly, who couldn’t afford this route, started exploring over-clocking, optimized hardware cooling... etc. to pursue the passion. Ever rising cost of hardware requirements lead to rampant piracy of PC games. Gamers were willing to spend on the latest titles, but the ones with tight budget prefer hardware upgrades against a legal copy of the game. It was also fueled by emergence of the P2P file sharing networks. Then came the era of Xbox and PS3s. It solved the major issue of hardware standardization and provided an alternative to ever increasing hardware costs. I have always admired these consoles, but being born and brought up in a keyboard/mouse environment, I still find it difficult to play first person shooters with a gamepad. I leave the topic of PC v/s Consol gaming for another day, but the bottom line is… PC gamers deserve an equally democratized solution. This is where I think Cloud Computing can come to rescue. It can minimize hardware requirements. Virtually end the software piracy and rationalize costs for gamers. Subscription based models like pay-as-you-play. In game rewards, like extended subscription credits for exceptional gamers (oh yes, I have beaten Xaero on nightmare in Quake III, time and again!) Easy deployment for patches and fixes. Better game AI. The list goes on and on… Fortunately, companies like OnLive are thinking in the same direction. Their gaming service is all set to launch on 17th June 2010 in E3 2010 expo in L.A. I wish them all the luck. I hope they will start a trend which will bring the smiles back on the face of budget gamers with the help of cloud computing.

• Intern Screening - Software 'Quiz'

  - by Jeremy1026

  I am in charge of selecting a new software development intern for a company that I work with. I wanted to throw a little 'quiz' at the applicants before moving forth with interviews so as to weed out the group a little bit to find some people that can demonstrate some skill. I put together the following quiz to send to applicants, it focuses only on PHP, but that is because that is what about 95% of the work will be done in. I'm hoping to get some feedback on A. if its a good idea to send this to applicants and B. if it can be improved upon. # 1. FizzBuzz # Write a small application that does the following: # Counts from 1 to 100 # For multiples of 3 output "Fizz" # For multiples of 5 output "Buzz" # For multiples of 3 and 5 output "FizzBuzz" # For numbers that are not multiples of 3 nor 5 output the number. <?php ?> # 2. Arrays # Create a multi-dimensional array that contains # keys for 'id', 'lot', 'car_model', 'color', 'price'. # Insert three sets of data into the array. <?php ?> # 3. Comparisons # Without executing the code, tell if the expressions # below will return true or false. <?php if ((strpos("a","abcdefg")) == TRUE) echo "True"; else echo "False"; //True or False? if ((012 / 4) == 3) echo "True"; else echo "False"; //True or False? if (strcasecmp("abc","ABC") == 0) echo "True"; else echo "False"; //True or False? ?> # 4.

• Why won't my code work in Ubuntu Server 11.10? Is it because of gd library?

  - by Derrick

  I get this error when running the following code: No such file found at "widgets/104-text.png" I know that the code works because it works on my other non-ubuntu server.

• Auto-organized / smart inventory system?

  - by VeXe

  for the past week I've been working on an inventory system with Unity3D. At first I got help from the guys at Design3 but it wasn't too long till we split path, because I really didn't like the way they did their code, it didn't have any smell of OOP whatsoever. I took it further steps ahead - items take more than one slot, advanced placement system (items tries their best to find the best close fit), local mouse system (mouse gets trapped in active bag area), etc. Here's a demo of my work. What we would like to have in our game, is an auto-organizing feature - not auto-sort. We want this feature because our inventory's going to be in 'real-time' - not like in Resident Evil 1,2,3 etc where you would pause the game and do things in your inventory. Now imagine your self in a sticky situation surrounded by zombies, and you don't have bullets, you look around, you see that there are bullets nearby on the ground, so you go for them and try to pick them up, but they don't fit! you look at your inventory and find out that if you reorganize some of the items, it will fit! - now the player - in that situation doesn't have time to reorganize because he's surrounded with zombies and will die if he stops and organizes the inventory to make space (remember inventory in real-time, no pausing) - wouldn't it be nice for that to happen automatically? - Yes! (I believe this has been implemented in some games like Dungeon siege or something, so sure it's doable) take a look at this picture for example: Yes, so if you auto-sort the issue you will get your spaces but it's bad because: 1- Expensive: it doesn't need a whole sort operation to free those spaces, in the first picture, just slide the red item at the bottom to the very left, and you get the same spaces that you got from the auto-sort. 2- It's annoying to the player: "Who the F told you to re-order my stuff?" I'm not asking for "How to write the code" for this, I'm just asking for some guidance, where to look, what algorithms are involved? Is this something related to graphs and shortest path stuff? I hope not cuz I didn't manage to continue my college studies :/ But even if it is, just tell me and I will learn the stuff related. Notice there could be more than just one solution. So I guess the first thing I have to do is figure out if the situation is 'solvable' - if I know how to determine if a situation is solvable or not, then I can 'solve' it. I just need to know the conditions that makes it 'solvable'. And I believe there must be some algorithm/data structure for this. Here's a pic for more than one solution of trying to fit a 1x3 item: The arrows show just one of the solutions, but if you look you will find more than one. This is what I ultimately not auto-sorting but find a solution and applying it. Note that if I spend time on it I will come up with a way to solve it, but it wouldn't be the best way, it's like, holding a car wheel with your feet instead of your hands! XD Or just like trying to solve an issue that requires arrays, but you're not yet aware of their existence! So what is the right approach to this? Hope somebody helps, thanks a lot in advance :)

• Is Visual Source Safe (The latest Version) really that bad? Why? What's the Best Alternative? Why? [closed]

  - by hanzolo

  Over the years I've constantly heard horror stories, had people say "Real Programmers Dont Use VSS", and so on. BUT, then in the workplace I've worked at two companies, one, a very well known public facing high traffic website, and another high end Financial Services "Web-Based" hosted solution catering to some very large, very well known companies, which is where I currently Reside and everything's working just fine (KNOCK KNOCK!!). I'm constantly interfacing with EXTREMELY Old technology with some of these financial institutions.. OLD LIKE YOU WOULDN'T BELIEVE.. which leads me to the conclusion that if it works "LEAVE IT", and that maybe there's some value in old technology? at least enough value to overrule a rewrite!? right?? Is there something fundamentally flawed with the underlying technology that VSS uses? I have a feeling that if i said "someone said VSS Sucks" they would beg to differ, most likely give me this look like i dont know -ish, and I'd never gain back their respect and my credibility (well, that'll be hard to blow.. lol), BUT, give me an argument that I can take to someone whose been coding for 30 years, that builds Platforms that leverage current technology (.NET 3.5 / SQL 2008 R2 ), write's their own ORM with scaffolding and is able to provide a quality platform that supports thousands of concurrent users on a multi-tenant hosted solution, and does not agree with any benefits from having Source Control Integrated, and yet uses the Infamous Visual Source Safe. I have extensive experience with TFS up to 2010, and honestly I think it's great when a team (beyond developers) can embrace it. I've worked side by side with someone whose a die hard SVN'r and from a purist standpoint, I see the beauty in it (I need a bit more, out of my SS, but it surely suffices). So, why are such smarties not running away from Visual Source Safe? surely if it was so bad, it would've have been realized by now, and I would not be sitting here with this simple old, Check In, Check Out, Version Resistant, Label Intensive system. But here I am... I would love to drop an argument that would be the end all argument, but if it's a matter of opinion and personal experience, there seems to be too much leeway for keeping VSS. UPDATE: I guess the best case is to have the VSS supporters check other people's experiences and draw from that until we (please no) experience the breaking factor ourselves. Until then, i wont be engaging in a discussion to migrate off of VSS.. UPDATE 11-2012: So i was able to convince everyone at my work place that since MS is sun downing Visual Source Safe it might be time to migrate over to TFS. I was able to convince them and have recently upgraded our team to Visual Studio 2012 and TFS 2012. The migration was fairly painless, had to run analyze.exe which found a bunch of errors (not sure they'll ever affect the project) and then manually run the VSSConverter.exe. Again, painless, except it took 16 hours to migrate 5 years worth of everything.. and now we're on TFS.. much more integrated.. much more cooler.. so all in all, VSS served it's purpose for years without hick-up. There were no horror stories and Visual Source Save as source control worked just fine. so to all the nay sayers (me included). there's nothing wrong with using VSS. i wouldnt start a new project with it, and i would definitely consider migrating to TFS. (it's really not super difficult and a new "wizard" type converter is due out any day now so migrating should be painless). But from my experience, it worked just fine and got the job done.

• How to parse a CSV file containing serialized PHP? [migrated]

  - by garbetjie

  I've just started dabbling in Perl, to try and gain some exposure to different programming languages - so forgive me if some of the following code is horrendous. I needed a quick and dirty CSV parser that could receive a CSV file, and split it into file batches containing "X" number of CSV lines (taking into account that entries could contain embedded newlines). I came up with a working solution, and it was going along just fine. However, as one of the CSV files that I'm trying to split, I came across one that contains serialized PHP code. This seems to break the CSV parsing. As soon as I remove the serialization - the CSV file is parsed correctly. Are there any tricks I need to know when it comes to parsing serialized data in CSV files? Here is a shortened sample of the code: use strict; use warnings; my $csv = Text::CSV_XS->new({ eol => $/, always_quote => 1, binary => 1 }); my $out; my $in; open $in, "<:encoding(utf8)", "infile.csv" or die("cannot open input file $inputfile"); open $out, ">outfile.000"; binmode($out, ":utf8"); while (my $line = $csv->getline($in)) { $lines++; $csv->print($out, $line); } I'm never able to get into the while loop shown above. As soon as I remove the serialized data, I suddenly am able to get into the loop. Edit: An example of a line that is causing me trouble (taken straight from Vim - hence the ^M): "26","other","1","20,000 Subscriber Plan","Some text here.^M\ Some more text","on","","18","","0","","0","0","recurring","0","","payment","totalsend","0","tsadmin","R34bL9oq","37","0","0","","","","","","","","","","","","","","","","","","","","","","","0","0","0","a:18:{i:0;s:1:\"3\";i:1;s:1:\"2\";i:2;s:2:\"59\";i:3;s:2:\"60\";i:4;s:2:\"61\";i:5;s:2:\"62\";i:6;s:2:\"63\";i:7;s:2:\"64\";i:8;s:2:\"65\";i:9;s:2:\"66\";i:10;s:2:\"67\";i:11;s:2:\"68\";i:12;s:2:\"69\";i:13;s:2:\"70\";i:14;s:2:\"71\";i:15;s:2:\"72\";i:16;s:2:\"73\";i:17;s:2:\"74\";}","","","0","0","","0","0","0.0000","0.0000","0","","","0.00","","6","1" "27","other","1","35,000 Subscriber Plan","Some test here.^M\ Some more text","on","","18","","0","","0","0","recurring","0","","payment","totalsend","0","tsadmin","R34bL9oq","38","0","0","","","","","","","","","","","","","","","","","","","","","","","0","0","0","a:18:{i:0;s:1:\"3\";i:1;s:1:\"2\";i:2;s:2:\"59\";i:3;s:2:\"60\";i:4;s:2:\"61\";i:5;s:2:\"62\";i:6;s:2:\"63\";i:7;s:2:\"64\";i:8;s:2:\"65\";i:9;s:2:\"66\";i:10;s:2:\"67\";i:11;s:2:\"68\";i:12;s:2:\"69\";i:13;s:2:\"70\";i:14;s:2:\"71\";i:15;s:2:\"72\";i:16;s:2:\"73\";i:17;s:2:\"74\";}","","","0","0","","0","0","0.0000","0.0000","0","","","0.00","","7","1" "28","other","1","50,000 Subscriber Plan","Some text here.^M\ Some more text","on","","18","","0","","0","0","recurring","0","","payment","totalsend","0","tsadmin","R34bL9oq","39","0","0","","","","","","","","","","","","","","","","","","","","","","","0","0","0","a:18:{i:0;s:1:\"3\";i:1;s:1:\"2\";i:2;s:2:\"59\";i:3;s:2:\"60\";i:4;s:2:\"61\";i:5;s:2:\"62\";i:6;s:2:\"63\";i:7;s:2:\"64\";i:8;s:2:\"65\";i:9;s:2:\"66\";i:10;s:2:\"67\";i:11;s:2:\"68\";i:12;s:2:\"69\";i:13;s:2:\"70\";i:14;s:2:\"71\";i:15;s:2:\"72\";i:16;s:2:\"73\";i:17;s:2:\"74\";}","","","0","0","","0","0","0.0000","0.0000","0","","","0.00","","8","1""73","other","8","10,000,000","","","","0","","0","","0","0","recurring","0","","payment","","0","","","75","0","10000000","","","","","","","","","","","","","","","","","","","","","","","0","0","0","a:17:{i:0;s:1:\"3\";i:1;s:1:\"2\";i:2;s:2:\"59\";i:3;s:2:\"60\";i:4;s:2:\"61\";i:5;s:2:\"62\";i:6;s:2:\"63\";i:7;s:2:\"64\";i:8;s:2:\"65\";i:9;s:2:\"66\";i:10;s:2:\"67\";i:11;s:2:\"68\";i:12;s:2:\"69\";i:13;s:2:\"70\";i:14;s:2:\"71\";i:15;s:2:\"72\";i:16;s:2:\"74\";}","","","0","0","","0","0","0.0000","0.0000","0","","","0.00","","14","0"

• .Net Windows Service Throws EventType clr20r3 system.data.sqlclient.sql error

  - by William Edmondson

  I have a .Net/c# 2.0 windows service. The entry point is wrapped in a try catch block yet when I look at the server's application event log I seem a number of "EventType clr20r3" errors that are causing the service to die unexpectedly. The catch block has a "catch (Exception ex)". Each sql commands is of the type "CommandType.StoredProcedure" and are executed with SqlDataReader's. These sproc calls function correctly 99% of time and have all been thoroughly unit tested, profiled, and QA'd. I additionally wrapped these calls in try catch blocks just to be sure and am still experiencing these unhandled exceptions. This only in our production environment and cannot be duplicated in our dev or staging environments (even under heavy load). Why would my error handling not catch this particular error? Is there anyway to capture more detail as to the root cause of the problem? Here is an example of the event log: EventType clr20r3, P1 RDC.OrderProcessorService, P2 1.0.0.0, P3 4ae6a0d0, P4 system.data, P5 2.0.0.0, P6 4889deaf, P7 2490, P8 2c, P9 system.data.sqlclient.sql, P10 NIL. Additionally The Order Processor service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.

• How can I run BitchX when I don't have ssh or shell access?

  - by Christopher

  I just installed an IRC bot, B****X (Don't ask, I don't know - the real name is not censored). I did all of the configuration and chmod'ed the pl files to 755, but running it won't work. My host does not allow SSH/Shell (which is how the documentation says to runs he script), but just going to the URL usually works because of this. However, I get a 500 (Internal Server Error) error. I have logged errors: Possible unintended interpolation of @moz in string at ./bitch.conf line 78 (#1) (W ambiguous) You said something like `@foo' in a double-quoted string but there was no array @foo in scope at the time. If you wanted a literal @foo, then write it as \@foo; otherwise find out what happened to the array you apparently lost track of.

• MySQL Connection Timeout Issue - Grails Application on Tomcat using Hibernate and ORM

  - by gav

  Hi Guys I have a small grails application running on Tomcat in Ubuntu on a VPS. I use MySql as my datastore and everything works fine unless I leave the application for more than half a day (8 hours?). I did some searching and apparently this is the default wait_timeout in mysql.cnf so after 8 hours the connection will die but Tomcat won't know so when the next user tries to view the site they will see the connection failure error. Refreshing the page will fix this but I want to get rid of the error altogether. For my version of MySql (5.0.75) I have only my.cnf and it doesn't contain such a parameter, In any case changing this parameter doesn't solve the problem. This Blog Post seems to be reporting a similar error but I still don't fully understand what I need to configure to get this fixed and also I am hoping that there is a simpler solution than another third party library. The machine I'm running on has 256MB ram and I'm trying to keep the number of programs/services running to a minimum. Is there something I can configure in Grails / Tomcat / MySql to get this to go away? Thanks in advance, Gav From my Catalina.out; 2010-04-29 21:26:25,946 [http-8080-2] ERROR util.JDBCExceptionReporter - The last packet successfully received from the server was 102,906,722 milliseconds$ 2010-04-29 21:26:25,994 [http-8080-2] ERROR errors.GrailsExceptionResolver - Broken pipe java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) ... 2010-04-29 21:26:26,016 [http-8080-2] ERROR util.JDBCExceptionReporter - Already closed. 2010-04-29 21:26:26,016 [http-8080-2] ERROR util.JDBCExceptionReporter - Already closed. 2010-04-29 21:26:26,017 [http-8080-2] ERROR servlet.GrailsDispatcherServlet - HandlerInterceptor.afterCompletion threw exception org.hibernate.exception.GenericJDBCException: Cannot release connection at java.lang.Thread.run(Thread.java:619) Caused by: java.sql.SQLException: Already closed. at org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:84) at org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.close(PoolingDataSource.java:181) ... 1 more

• How do I make the 32-bit Perl read the 64-bit Windows registry?

  - by Santhosh

  I have a 32-bit perl installer. Using this I need to be able to install and uninstall both 32- and 64-bit applications. Installing 32- and 64-bit is fine. Uninstalling 32-bit is also ok. However, I have a problem while uninstalling 64-bit applications. The application just knows the name of the application as seen in Add Remove programs in control panel. For instance it could be "Winzip 14.0" which is the display name for Winzip. I use the following approach for uninstallation : I traverse to HKLM/Software/Microsoft/Windows/CurrentVersion/Uninstall and parse the keys present there to see if Winzip is matching. If so i get the uninstall string from there. my $register = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"; $HKEY_LOCAL_MACHINE->Open($register,$hKey)|| die $!; #Then parse all the nodes and fetch the uninstall string If the application is a 64-bit installation, then the uninstallation information will reside in HKLM/Software/Microsoft/Windows/CurrentVersion/Uninstall. However the above given perl installer code is trying to read from HKLM/Software/WOW6432Node/Microsoft/Windows/CurrentVersion/Uninstall and it does not find the installation there. So how do I make the Perl code running in a 32_bit process to read the registry value found in 64-bit hive? I am aware of the RegOpenKey() API that takes KEY_WOW64_64KEY parameter. But since it is a Windows API, I dont know if that will help. Even then, is there any other alternative?

• How to get current Joomla user with external PHP script

  - by Joey Adams

  I have a couple PHP scripts used for AJAX queries, but I want them to be able to operate under the umbrella of Joomla's authentication system. Is the following safe? Are there any unnecessary lines? joomla-auth.php (located in the same directory as Joomla's index.php): <?php define( '_JEXEC', 1 ); define('JPATH_BASE', dirname(__FILE__)); define( 'DS', DIRECTORY_SEPARATOR ); require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); /* Create the Application */ $mainframe =& JFactory::getApplication('site'); /* Make sure we are logged in at all. */ if (JFactory::getUser()->id == 0) die("Access denied: login required."); ?> test.php: <?php include 'joomla-auth.php'; echo 'Logged in as "' .

• Wrapping malloc - C

  - by Appu

  I am a beginner in C. While reading git's source code, I found this wrapper function around malloc. void *xmalloc(size_t size) { void *ret = malloc(size); if (!ret && !size) ret = malloc(1); if (!ret) { release_pack_memory(size, -1); ret = malloc(size); if (!ret && !size) ret = malloc(1); if (!ret) die("Out of memory, malloc failed"); } #ifdef XMALLOC_POISON memset(ret, 0xA5, size); #endif return ret; } Questions I couldn't understand why are they using malloc(1)? What does release_pack_memory does and I can't find this functions implementation in the whole source code. What does the #ifdef XMALLOC_POISON memset(ret, 0xA5, size); does? I am planning to reuse this function on my project. Is this a good wrapper around malloc? Any help would be great.

• Call asp.net mvc Html Helper within custom html helper with expression parameter

  - by Frank Michael Kraft

  I am trying to write an html helper extension within the asp.net mvc framework. public static MvcHtmlString PlatformNumericTextBoxFor<TModel>(this HtmlHelper instance, TModel model, Expression<Func<TModel,double>> selector) where TModel : TableServiceEntity { var viewModel = new PlatformNumericTextBox(); var func = selector.Compile(); MemberExpression memExpession = (MemberExpression)selector.Body; string name = memExpession.Member.Name; var message = instance.ValidationMessageFor<TModel, double>(selector); viewModel.name = name; viewModel.value = func(model); viewModel.validationMessage = String.Empty; var result = instance.Partial(typeof(PlatformNumericTextBox).Name, viewModel); return result; } The line var message = instance.ValidationMessageFor<TModel, double>(selector); has a syntax error. But I do not understand it. The error is: Fehler 2 "System.Web.Mvc.HtmlHelper" enthält keine Definition für "ValidationMessageFor", und die Überladung der optimalen Erweiterungsmethode "System.Web.Mvc.Html.ValidationExtensions.ValidationMessageFor(System.Web.Mvc.HtmlHelper, System.Linq.Expressions.Expression)" weist einige ungültige Argumente auf. C:\Projects\WorkstreamPlatform\WorkstreamPlatform_WebRole\Extensions\PlatformHtmlHelpersExtensions.cs 97 27 WorkstreamPlatform_WebRole So according to the message, the parameter is invalid. But the method is actually declared like this: public static MvcHtmlString ValidationMessageFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression); So actually it should work.

• PHP session_write_close() causes empty response

  - by Xeoncross

  When using session_write_close() in a shutdown function at the end of my script - PHP just dies. There is no error logged, response headers (firebug), or data (even whitespace!) returned. I have full PHP error reporting on with STRICT enabled and PHP 5.2.1. My guess is that since session_write_close() is being called after shutdown - some fatal error is being encountered that crashes PHP before it has a chance to send the output or log anything. This only happens on the logout page where I first: ... //If there is no session to delete (not started) if ( ! session_id()) { return; } // Get the session name $name = session_name(); // Delete the session cookie (if exists) if ( ! empty($_COOKIE[$name])) { //Get the current cookie config $params = session_get_cookie_params(); // Delete the cookie from globals unset($_COOKIE[$name], $_SESSION); //Delete the cookie on the user_agent setcookie($name, '', time()-43200, $params['path'], $params['domain'], $params['secure']); } // Destroy the session session_destroy(); ... then 2) do some more stuff 3) issue a redirect and 4) finally, after the whole page is done the register_shutdown_function(); I placed earlier runs and calls session_write_close() which saves the session to the database. The end. Since this blank response only occurs on logout I'm guessing that I'm not restarting the session properly which is causing session_write_close() to die fatally at the end of the script.

• jQuery addClass on $.post

  - by Tim

  I am basically trying to create a small registration form. If the username is already taken, I want to add the 'red' class, if not then 'green'. The PHP here works fine, and returns either a "YES" or "NO" to determine whether it's ok. The CSS: input { border:1px solid #ccc; } .red { border:1px solid #c00; } .green { border:1px solid green; background:#afdfaf; } The Javascript I'm using is: $("#username").change(function() { var value = $("#username").val(); if(value!= '') { $.post("check.php", { value: value }, function(data){ $("#test").html(data); if(data=='YES') { $("#username").removeClass('red').addClass('green'); } if(data=='NO') { $("#username").removeClass('green').addClass('red'); } }); } }); I've got the document.ready stuff too... It all works fine because the #test div html changes to either "YES" or "NO", apart from the last part where I check what the value of the data is. Here is the php: $value=$_POST['value']; if ($value!="") { $sql="select * FROM users WHERE username='".$value."'"; $query = mysql_query($sql) or die ("Could not match data because ".mysql_error()); $num_rows = mysql_num_rows($query); if ($num_rows 0) { echo "NO"; } else { echo "YES"; } }

• Post on a logged in users facebook wall

  - by Matt Nathanson

  Hey all, I've created a widget that will essentially unlock a music track, providing you post to either your twitter account, or facebook wall. I've signed up through facebook connect and I am able to successfully post onto my own wall... but the functionality I'm looking for is to be able to take ones username and password and automatically log in to facebook, and send my desired message. Like I said, it posts on my wall successfully, it's just not using the username and password from the field to log in to their respective facebooks and post. <?php $facename = $_POST['facename']; $facepass = $_POST['facepass']; define('FB_APIKEY', 'my_api_key'); define('FB_SECRET', 'my_secret_phrase_'); define('FB_SESSION', 'my_session_id'); require_once('facebook.php'); echo "post on wall"; try { $facebook = new Facebook(FB_APIKEY, FB_SECRET); $facebook->api_client->session_key = FB_SESSION; $fetch = array('friends' => array('pattern' => '.*', 'query' => "select uid2 from friend where uid1={$facename}")); echo $facebook->api_client->admin_setAppProperties(array('preload_fql' => json_encode($fetch))); $message = 'I downloaded Automatic Loveletter\'s new single \'To Die For\' here!'; if( $facebook->api_client->stream_publish($message)) echo "Added on FB Wall"; } catch(Exception $e) { echo $e .

• Eclipse RAP - Firefox doesn't forget session

  - by Fritz H

  We've got an Eclipse RAP application that's behaving a bit strangely in Firefox - two distinct problems. When you browse around, you can click on a button in one part of the system. This opens a popup window like so: IWorkbenchBrowserSupport bs; bs = PlatformUI.getWorkbench().getBrowserSupport(); int style = IWorkbenchBrowserSupport.AS_EXTERNAL; IWebBrowser b = bs.createBrowser(style, getRandomID(), "Hello world", ""); b.openURL(new URL(...)); where the URL is another servlet in the application. This servlet is in the same runtime, but has nothing to do with RAP - it takes a binary blob from in-memory storage and dumps it in the output stream. Problem 1: This causes the HTTP session to die in firefox, and shows the "session expired" RAP error page with a link to restart the session. Problem 2: Now, when you click on the link to restart the session, it shows the application's dialog again, but the session expired error is shown again the moment you do anything. This prevents the user from using the system again, unless Firefox is closed down completely and restarted. A quick peek with FireBug reveals that the JSESSIONID passed by Firefox does not change. Has anyone seen this before?

• Using NSURLRequest to pass key-value pairs to PHP script with POST

  - by Ralf Mclaren

  Hi, I'm fairly new to objective-c, and am looking to pass a number of key-value pairs to a PHP script using POST. I'm using the following code but the data just doesn't seem to be getting posted through. I tried sending stuff through using NSData as well, but neither seem to be working. NSDictionary* data = [NSDictionary dictionaryWithObjectsAndKeys: @"bob", @"sender", @"aaron", @"rcpt", @"hi there", @"message", nil]; NSURL *url = [NSURL URLWithString:@"http://myserver.com/script.php"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[NSData dataWithBytes:data length:[data count]]]; NSURLResponse *response; NSError *err; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; NSLog(@"responseData: %@", content); This is getting sent to this simple script to perform a db insert: <?php $sender = $_POST['sender']; $rcpt = $_POST['rcpt']; $message = $_POST['message']; //script variables include ("vars.php"); $con = mysql_connect($host, $user, $pass); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("mydb", $con); mysql_query("INSERT INTO php_test (SENDER, RCPT, MESSAGE) VALUES ($sender, $rcpt, $message)"); echo "complete" ?> Any ideas?
