• Is it possible to use instanceof when passing objects between Threads?

  - by Risser

  I've run into an issue where instanceof works, and then it doesn't. Going into details is difficult, but I think this might be the problem: Reading this: http://www.theserverside.com/news/thread.tss?thread_id=40229 (search for Thread.currentThread), it seems to imply that, even if the two objects are the same class, if you pass them between threads with different class loaders, instanceof (and isAssignableFrom) might still fail. This certainly would explain the behavior I'm having, but I was wondering if anyone could verify it? (I wish the article linked at the beginning of the discussion was still available, but it doesn't seem like it is.) Thanks, Peter

• Ideas for band site, which technology to use?

  - by brux

  I am attempting to design and build a website for my friends band. There is minimal content to be included such as bio,news,enbemdded Audio/Visual material. My web dev expertise is average. I'm basicaly looking for inspiration, I was edging towards embedding a silverlight deepzoom xap object to add some visual stimulation, perhaps by featuring a high res photo of the bandshardware/equipment which zooms when mouseover occurs. Does anyone have any cool ideas for a central feature for this site, and which way to approact it in terms of technique (js,css,silverlight etc) If anyone has any immediate ideas which they think would be cool then I am eager to hear them! Also if anyone can link me to any cool band sites they have come across recently I would be greatful,nothing too complicated though please I will be doing all the work myself. Im want the site to be simple but have a certain wow factor!

• Postfix Bounced Emails With Google Apps

  - by crontab

  So our company uses Google Apps to handle our accounts for our employees. Meaning something like [email protected] would go to Google Apps. We also use postfix on our server to send out our news letter emails to our users. We've setup our emails to have a unique return-path which is basically [email protected] problem is that when postfix gets a bounce during the SMTP connection, it actually sends out the email to Google Apps. Is there anyway that we can setup Postfix to not send to [email protected] and instead pipe that message to a script which we can grab the original message and log the bounced address? I realize this only partially works as some emails may send correctly from postfix and then bounce down the road somewhere, but this should help us out with a good portion of our bounces. For a start, in main.cf we have recipient_delimiter = + and in master.cf we have bouncehandler unix - n n - - pipe user=nobody argv=/path/to/bounce_handler.php ${recipient} Not really sure where to go from here though.

• iPhone RSS Reader -- parseXML won't Load some XML feeds

  - by JBMJBM

  I am using the SIMPLE RSS reading example found at http://theappleblog.com/2008/08/04/tutorial-build-a-simple-rss-reader-for-iphone/ It uses parseXML to load the RSS feeds. Here is the problem I am having. For the following RSS feed example, I am having trouble getting it to load the feed. Comes up with an error that it cannot connect. However on my Mac RSS Reader it works fine, so I know the link is good. Any ideas on why it cannot load this particular feed but it can load others fine? http://www.okstate.com/rss.dbml?db_oem_id=200&media=news Thanks.

• NoSQL replacement for memcache

  - by Juan Antonio Gomez Moriano

  We are having a situation in which the values we store on memcache are bigger than 1MB. It is not possible to make such values smaller, and even if there was a way, we need to persist them to disk. One solution would be to recompile the memcache server to allow say 2MB values, but this is either not clean nor a complete solution (again, we need to persist the values). Good news is that We can predict quite acurately how many key/values pair we are going to have We can also predict the total size we will need. A key feature for us is the speed of memcache. So question is: is there any noSQL replacement for memcache which will allow us to have values longer than 1MB AND store them in disk without loss of speed? In the past I have used tokyotyrant/cabinet but seems to be deprecated now. Any idea?

• Running python/ruby script on iPhone?

  - by prosseek

  From the recent news from the Apple, I learned that one has to use C/C++/Objective-C for iPhone App. Accordingly, it's not possible to use MacPython or similar to make iPhone App. But as the python/ruby interpreter itself is written in C, isn't it OK to make python/ruby interpreter for iPhone to run the scripts on iphone? Is this possible? Does Apple support this? Or does someone implemented this? Or, the user should hack to do this?

• Problems with Facebook API - Getting all content from table Stream

  I am trying to get all stream data from a group (I have wall entries, discussions, events and photos). For now, Access on this group is Open. $result = $_fb-api_client-fql_query("SELECT actor_id, message FROM stream WHERE source_id=$gid LIMIT 50"); Only some of the records come back (5 out of 10) (only wall entries and a photo).

• Warn user when new data is inserted on database

  - by João Menighin

  I don't know how to search about this so I'm kinda lost (the two topics I saw here were closed). I have a news website and I want to warn the user when a new data is inserted on the database. I want to do that like here on StackOverflow where we are warned without reloading the page or like in facebook where you are warned about new messages/notifications without reloading. Which is the best way to do that? Is it some kind of listener with a timeout that is constantly checking the database? It doesn't sounds efficient... Thanks in advance.

• Where does one enter the JavaScript code in CRM Dynamics?

  - by Konrad Viltersten

  I've started to play with CRM Dynamics yesterday so this question should be seen as a very basic one. I've been coding for many years but CRM D is news to me. Apparently, one is supposed to be able to enter JavaScript code to customize the behavior of the application. I've understood that there's an API for that and that touching DOM directly or playing with jQuery is a no-no. Question: Where is the JS-code supposed to be entered? I've gone through all the menus but as far I can see, there's no spot where I could plug-in my custom code. E.g.: Where do I get to define a validation for the last name of a contact currently being defined?

• a question related to Google Translate

  - by Robert

  Hi all, it works perfectly fine if I paste the following URL directly into my IE address bar: http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED it will translate some Chinese news pages into English ones. but if I call this address in a Java program like: Process q=Runtime.getRuntime().exec("cmd /c start http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED"); It will only return to the Google translate main page. Wonder what went wrong there. and it would be great if you help me how to realize this(opening the Google translated result page simplying by supplying the URL,in a Java program). Many thanks.

• add/delete image ID to/from textbox when image clicked

  - by Huseyin

  I am working on a simple news module. There is a form where user adds multiple image IDs to one textbox then submits it. To improve the usability, I listed all the images they can add (ID numbers displayed next to it) on one side. However, this still is little bit confusing. I want image IDs added/deleted to the textbox when user clicks on the images. Spare me codes, methods, ideas, examples... I will take anything.

• Are there any well-known algorithms or computer models that computer scientists use to predict FIFA

  - by Khnle

  Occasionally I read news articles that mention about some computer models that computer scientists use to predict winners of some sporting events or the odds for betting which I think there must be a mathematical model behind it. I never bothered to think twice even though I am a "pseudo computer scientist" myself. With the 2010 FIFA World Cup just underway, and since I am also a "pseudo football/soccer player" myself, I just started to wonder about these calculations algorithms. For example, I know one factor is determining the strength of opponents, so that a win against a strong opponent can count more than a win against a weak opponent. But it now kind of gets in a circular loop, or at least how does one determine the strength of a team in the first place, before that team can be considered strong or weak? If it's based on a historical data then there's no way that could be accurate, because those players of the past are no longer on the fields so their impact is none (except maybe if they become coaches like Maradona) Anyway, long question short, if you're happen to be working in this field or have some knowledge, please shed some lights.

• Development Applications on big devices vs mobile phones: Similarities/Disimilarities

  - by Richard77

  Hello, I saw a news document on applications running in mobile devices. And, I believe that might be interesting for people where I live (Internet is not developed - but the cellphone networks are much better). So here are my questions: Where can I find documentation for beginners on that matter (And most importantly) Am I gonna be able to take advantage of acquired knowledge in .NET framework (C#, MVC, JQuery, XHTML, ...)? Am I gonna need my laptop or a special device to develop applications? Am I gonna need Visual Studio? And so on... Bref, What are similarities/dissimilarities between developments for applications running in big machines and those running on mobile phones? Thanks for helping

• php and XML range into array

  The code below helps be to get the WHOLE XML and put it into an array. What I'm wondering is, what would be a good way to get the XML only from item 3 - 6 or any arbitrary range instead of the whole document. $mt_arr = array(); $d = new DOMDocument(); $d->load('http://news.google.com/?output=rss'); foreach ($d->getElementsByTagName('item') as $t) { $list = array ( 'title' => $t->getElementsByTagName('title')->item(0)->nodeValue); array_push($mt_arr, $list); } Thanks

• iPad --- managedObject problem when [self.tableViewSection reloadData]

  - by user345777

  Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

• Problem installing wordpress child themes.

  - by Jay

  Hi, I've tried to install either the Fusion or Thematic child themes for my blog. My Wordpress directory is located at myblog/wordpress while my domain is just myblog (example). Everything works fine with both basic themes or the parent Fusion or Thematic themes. When I install a child theme for either framework, I can view the preview and select 'activate.' However, after that my entire site crashes. I can't even view the wordpress admin panel. I've had to restore my database from my hosting provider just to get my blog working. All that I'm able to see is my favicon icon and a blank page. I've tried to deactivate all plugins and this doesn't help either. I really want to use the Hybrid News child template. Any thoughts on what might be happening? thanks so much!
