• multipart file-upload post request from java

  - by Martin

  I'm trying to make a program that uploads a image to a webserver that accepts multipart file-uploads. More specificly i want to make a http POST request to http://iqs.me that sends a file in the variable "pic". I've made a lot of tries but i don't know if i've even been close. The hardest part seems to be to get a HttpURLConnection to make a request of the type POST. The response i get looks like it makes a GET. (And i want to do this without any third party libs) UPDATE: non-working code goes here (no errors but doesn't seem to do a POST): HttpURLConnection conn = null; BufferedReader br = null; DataOutputStream dos = null; DataInputStream inStream = null; InputStream is = null; OutputStream os = null; boolean ret = false; String StrMessage = ""; String exsistingFileName = "myScreenShot.png"; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1*1024*1024; String responseFromServer = ""; String urlString = "http://iqs.local.com/index.php"; try{ FileInputStream fileInputStream = new FileInputStream( new File(exsistingFileName) ); URL url = new URL(urlString); conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestMethod("POST"); conn.setUseCaches(false); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); dos = new DataOutputStream( conn.getOutputStream() ); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"pic\";" + " filename=\"" + exsistingFileName +"\"" + lineEnd); dos.writeBytes(lineEnd); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0){ dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); fileInputStream.close(); dos.flush(); dos.close(); }catch (MalformedURLException ex){ System.out.println("Error:"+ex); }catch (IOException ioe){ System.out.println("Error:"+ioe); } try{ inStream = new DataInputStream ( conn.getInputStream() ); String str; while (( str = inStream.readLine()) != null){ System.out.println(str); } inStream.close(); }catch (IOException ioex){ System.out.println("Error: "+ioex); }

• RackSpace Cloud Strips $_SESSION if URL Has Certain File Extensions

  - by macinjosh

  The Situation I am creating a video training site for a client on the RackSpace Cloud using the traditional LAMP stack (RackSpace's cloud has both Windows and LAMP stacks). The videos and other media files I'm serving on this site need to be protected as my client charges money for access to them. There is no DRM or funny business like that, essentially we store the files outside of the web root and use PHP to authenticate user's before they are able to access the files by using mod_rewrite to run the request through PHP. So let's say the user requests a file at this URL: http://www.example.com/uploads/preview_image/29.jpg I am using mod_rewrite to rewrite that url to: http://www.example.com/files.php?path=%2Fuploads%2Fpreview_image%2F29.jpg Here is a simplified version of the files.php script: <?php // Setups the environment and sets $logged_in // This part requires $_SESSION require_once('../../includes/user_config.php'); if (!$logged_in) { // Redirect non-authenticated users header('Location: login.php'); } // This user is authenticated, continue $content_type = "image/jpeg"; // getAbsolutePathForRequestedResource() takes // a Query Parameter called path and uses DB // lookups and some string manipulation to get // an absolute path. This part doesn't have // any bearing on the problem at hand $file_path = getAbsolutePathForRequestedResource($_GET['path']); // At this point $file_path looks something like // this: "/path/to/a/place/outside/the/webroot" if (file_exists($file_path) && !is_dir($file_path)) { header("Content-Type: $content_type"); header('Content-Length: ' . filesize($file_path)); echo file_get_contents($file_path); } else { header('HTTP/1.0 404 Not Found'); header('Status: 404 Not Found'); echo '404 Not Found'; } exit(); ?> The Problem Let me start by saying this works perfectly for me. On local test machines it works like a charm. However once deployed to the cloud it stops working. After some debugging it turns out that if a request to the cloud has certain file extensions like .JPG, .PNG, or .SWF (i.e. extensions of typically static media files.) the request is routed to a cache system called Varnish. The end result of this routing is that by the time this whole process makes it to my PHP script the session is not present. If I change the extension in the URL to .PHP or if I even add a query parameter Varnish is bypassed and the PHP script can get the session. No problem right? I'll just add a meaningless query parameter to my requests! Here is the rub: The media files I am serving through this system are being requested through compiled SWF files that I have zero control over. They are generated by third-party software and I have no hope of adding or changing the URLs that they request. Are there any other options I have on this? Update: I should note that I have verified this behavior with RackSpace support and they have said there is nothing they can do about it.

• WordPress issues with htaccess causing 500 server error

  - by Scott B

  I have a few customers of my custom wordpress theme that are reporting that their sites have went down over the past few weeks due to a 500 internal server error. In each case, it appears that the htaccess file has been to blame. In one case, the user's hosting company found a "_pvt/service.pwd" line in there that was apparently causing the problem. In another instance, the hosting company indicated that a chron job appeared to be causing the issue and sent the user the following as evidence... root@cherry [/home/login/public_html]# stat .htaccess File: `.htaccess.orig' Size: 587 Blocks: 8 IO Block: 4096 regular file Device: 811h/2065d Inode: 590021607 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 2234/login) Gid: ( 2231/login) Access: 2010-03-07 16:42:01.000000000 -0600 Modify: 2010-03-26 09:15:15.000000000 -0500 Change: 2010-03-26 09:45:05.000000000 -0500 In yet another instance, the user reported this as the cause... The permissions on my .index file somehow got changed to 777 instead of 644 I'm just seeking to help these users understand what's going on, the likely cause and how to prevent it. I also want to eliminate my theme as a potential contributing factor. I have two areas in which I want to submit here to make sure that they are not likely to cause such an issue. They are my permalink rewrite code as well as my upgrade script (which sets 755 on the destination folder (my theme folder). Here's the permalink rewrite code... if (file_exists(ABSPATH.'/wp-admin/includes/taxonomy.php')) { require_once(ABSPATH.'/wp-admin/includes/taxonomy.php'); if(get_option('permalink_structure') !== "/%postname%/" || get_option('mycustomtheme_permalinks') !=="/%postname%/") { $mycustomtheme_permalinks = get_option('mycustomtheme_permalinks'); require_once(ABSPATH . '/wp-admin/includes/misc.php'); require_once(ABSPATH . '/wp-admin/includes/file.php'); global $wp_rewrite; $wp_rewrite->set_permalink_structure($mycustomtheme_permalinks); $wp_rewrite->flush_rules(); } if(!get_cat_ID('topMenu')){wp_create_category('topMenu');} if(!get_cat_ID('hidden')){wp_create_category('hidden');} if(!get_cat_ID('noads')){wp_create_category('noads');} } if (!is_dir(ABSPATH.'wp-content/uploads')) { mkdir(ABSPATH.'wp-content/uploads'); } And here is the relevant lines from my uploader script... // permission settings for newly created folders $chmod = 0755; // Ensures that the correct file was chosen $accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/s-compressed'); foreach($accepted_types as $mime_type) { if($mime_type == $type) { $okay = true; break; } } //Safari and Chrome don't register zip mime types. Something better could be used here. $okay = strtolower($name[1]) == 'zip' ? true: false; if(!$okay) { die("This upgrader requires a zip file. Please make sure your file is a valid zip file with a .zip extension"); } //mkdir($target); $saved_file_location = $target . $filename; if(move_uploaded_file($source, $saved_file_location)) { openZip($saved_file_location); } else { die("There was a problem. Sorry!"); }

• ubuntu one not syncing

  - by Martin

  I am really starting to despair as I have been trying ubuntu one for several months, trying it on several machines, and it has caused me loads of different issues wasting me a lot of time. It is not straight forward to use, it should be a piece of software that runs in background and users should not think about checking all the time if it is really doing it's job. Of course I have been searching around this website and other forums but couldn't find an answer to my situation. Yesterday I had several problems with the client not syncing and using a lot of the machine's RAM, up and CPU. I had to reboot on several occasions and leave the office's PC on overnight in order to sync a few files of not more than a few MB. Today I am experiencing another problem: I have decided to do a test putting a small file in my ubuntu one shared folder. Ubuntu one is not detecting it (now already more than an hour), therefore not uploading it to the server. martin@ubuntu-desktop:~$ u1sdtool --status State: QUEUE_MANAGER connection: With User With Network description: processing the commands pool is_connected: True is_error: False is_online: True queues: IDLE and martin@ubuntu-desktop:~$ u1sdtool --current-transfers Current uploads: 0 Current downloads: 0 I am running Ubuntu 11.04 64 with all recent updates. On my other machine the transfer of files seems to be completely frozen, with around 10 files in the queue but no transfer whatsoever. Another curious issue is on my Ubuntu 10.10 laptop where ubuntu one seems to have completly disappeared from Nautilus context menu, folder/file sync status icons missing. I have therefore been forced to upgrade to 11.04 on this machine. Anyway, now I would like to solve the ** processing the commands pool ** issue and make sure the client

• How does Ubuntu One work? Files seem to upload but can not be accessed on another system

  - by JQPublic

  I have two computers running 12.04, I sign into my Ubuntu 0ne account on each computer, "Hi JQPublic" both say. Do I understand correctly that placing a file (specifically an .ogg music file ... simply a song) into the "Ubuntu One" file folder (always synced) on one computer, I should be able to open the "Ubuntu One" file folder on the other computer and find said .ogg, right? That is how this is meant to work, yes? Because it's not what's happening. Nothing uploads (though the first computer claims such). Minutes pass, still nothing. A different experiment: I uploaded a file folder containing a song; the folder was available on both computers, but remained decidedly empty. Any suggestions? I'm otherwise LOVING my return to Ubuntu (left at 9.04). I really am inclined to think that I'm missing something HUGE, that this is all a user (me) error, not a bug ... is it me? All help appreciated. Peace, JQPublic

• Manage Sending 2010 Documents to the Web with Office Upload Center

  - by Mysticgeek

  One of the main new features being touted in Office 2010 is the ability to upload documents to the Web for sharing and collaboration. Today we look at using Office Upload Center to help manage your uploaded documents. Microsoft Office Upload Center  When you upload an Office 2010 document to the web, a handy tool to manage them is the Office Upload Center. It’s a way to see what is being uploaded or what might have failed to reach the servers. It lets you know if a document failed to upload for some reason. In this case it looks like the incorrect credentials were entered when signing into Windows Live. Click on the Resolve button to get a list of actions you can take to get things corrected.   You can access the Upload Center from the icon which appears on the System Tray when uploading documents. Right-click the icon to control notifications, pause uploads, and access its settings. In the Settings section you can choose how Upload Center displays notifications, select the number of days to keep files in Cache, and delete currently cached files. If you find yourself uploading several documents to the web during the day, the Office Upload Center is a nice feature for managing them.

• What's New in Database Lifecycle Management in Enterprise Manager 12c Release 3

  - by HariSrinivasan

  Enterprise Manager 12c Release 3 includes improvements and enhancements across every area of the product. This blog provides an overview of the new and enhanced features in the Database Lifecycle Management area. I will deep dive into specific features more in depth in subsequent posts. "What's New?"  In this release, we focused on four things: 1. Lifecycle Management Support for new Database12c - Pluggable Databases 2. Management of long running processes, such as a security patch cycle (Change Activity Planner) 3. Management of large number of systems by · Leveraging new framework capabilities for lifecycle operations, such as the new advanced ‘emcli’ script option · Refining features such as configuration search and compliance 4. Minor improvements and quality fixes to existing features · Rollback support for Single instance databases · Improved "OFFLINE" Patching experience · Faster collection of ORACLE_HOME configurations Lifecycle Management Support for new Database 12c - Pluggable Databases Database 12c introduces Pluggable Databases (PDBs), the brand new addition to help you achieve your consolidation goals. Pluggable databases offer unprecedented consolidation at database level and native lifecycle verbs for creating, plugging and unplugging the databases on a container database (CDB). Enterprise Manager can supplement the capabilities of pluggable databases by offering workflows for migrating, provisioning and cloning them using the software library and the deployment procedures. For example, Enterprise Manager can migrate an existing database to a PDB or clone a PDB by storing a versioned copy in the software library. One can also manage the planned downtime related to patching by  migrating the PDBs to a new CDB. While pluggable databases offer these exciting features, it can also pose configuration management and compliance challenges if not managed properly. Enterprise Manager features like inventory management, topology associations and configuration search can mitigate the sprawl of PDBs and also lock them to predefined golden standards using configuration comparison and compliance rules. Learn More ... Management of Long Running datacenter processes - Change Activity Planner (CAP) Currently, customers resort to cumbersome methods to create, execute, track and monitor change activities within their data center. Some customers use traditional tools such as spreadsheets, project planners and in-house custom built solutions. Customers often have weekly sync up meetings across stake holders to collect status and updates. Some of the change activities, for example the quarterly patch set update (PSU) patch rollouts are not single tasks but processes with multiple tasks. Some of those tasks are performed within Enterprise Manager Cloud Control (for example Patch) and some are performed outside of Enterprise Manager Cloud Control. These tasks often run for a longer period of time and involve multiple people or teams. Enterprise Manger Cloud Control supports core data center operations such as configuration management, compliance management, and automation. Enterprise Manager Cloud Control release 12.1.0.3 leverages these capabilities and introduces the Change Activity Planner (CAP). CAP provides the ability to plan, execute, and track change activities in real time. It covers the typical datacenter activities that are spread over a long period of time, across multiple people and multiple targets (even target types). Here are some examples of Change Activity Process in a datacenter: · Patching large environments (PSU/CPU Patching cycles) · Upgrading large number of database environments · Rolling out Compliance Rules · Database Consolidation to Exadata environments CAP provides user flows for Compliance Officers/Managers (incl. lead administrators) and Operators (DBAs and admins). Managers can create change activity plans for various projects, allocate resources, targets, and groups affected. Upon activation of the plan, tasks are created and automatically assigned to individual administrators based on target ownership. Administrators (DBAs) can identify their tasks and understand the context, schedules, and priorities. They can complete tasks using Enterprise Manager Cloud Control automation features such as patch plans (or in some cases outside Enterprise Manager). Upon completion, compliance is evaluated for validations and updates the status of the tasks and the plans. Learn More about CAP ...  Improved Configuration & Compliance Management of a large number of systems Improved Configuration Comparison:  Get to the configuration comparison results faster for simple ad-hoc comparisons. When performing a 1 to 1 comparison, Enterprise Manager will perform the comparison immediately and take the user directly to the results without having to wait for a job to be submitted and executed. Flattened system comparisons reduce comparison setup time and reduce complexity. In addition to the previously existing topological comparison, users now have an option to compare using a “flattened” methodology. Flattening means to remove duplicate target instances within the systems and remove the hierarchy of member targets. The result are much easier to spot differences particularly for specific use cases like comparing patch levels between complex systems like RAC and Fusion Apps. Improved Configuration Search & Advanced EMCLI Script option for Mass Automation Enterprise manager 12c introduces a new framework level capability to be able to script and stitch together multiple tasks using EMCLI. This powerful capability can be leveraged for lifecycle operations, especially when executing a task over a large number of targets. Specific usages of this include, retrieving a qualified list of targets using Configuration Search and then using the resultset for automation. Another example would be executing a patching operation and then re-executing on targets where it may have failed. This is complemented by other enhancements, such as a better usability for designing reusable configuration searches. IN EM 12c Rel 3, a simplified UI makes building adhoc searches even easier. Searching for missing patches is a common use of configuration search. This required the use of the advanced options which are now clearly defined and easy to use. Perform “Configuration Search” using the EMCLI. Users can find and execute Configuration Searches from the EMCLI which can be extremely useful for building sophisticated automation scripts. For an example, Run the Search named “Oracle Databases on Exadata” which finds all Database targets running on top of Exadata. Further filter the results by refining by options like name, host, etc.. emcli get_targets -config_search="Databases on Exadata" –target_name="exa%“ Use this in powerful mass automation operations using the new emcli script option. For example, to solve the use case of – Finding all DBs running on Exadata and housing E-Biz and Patch them. Create a Python script with emcli functions and invoke it in the new EMCLI script option shell. Invoke the script in the new EMCLI with script option directly: $<path to emcli>/emcli @myPSU_Patch.py Richer compliance content:  Now over 50 Oracle Provided Compliance Standards including new standards for Pluggable Database, Fusion Applications, Oracle Identity Manager, Oracle VM and Internet Directory. 9 Oracle provided Real Time Monitoring Standards containing over 900 Compliance Rules across 500 Facets. These new Real time Compliance Standards covers both Exadata Compute nodes and Linux servers. The result is increased Oracle software coverage and faster time to compliance monitoring on Exadata. Enhancements to Patch Management: Overhauled "OFFLINE" Patching experience: Simplified Patch uploads UI to improve the offline experience of patching. There is now a single step process to get the patches into software library. Customers often maintain local repositories of patches, sometimes called software depots, where they host the patches downloaded from My Oracle Support. In the past, you had to move these patches to your desktop then upload them to the Enterprise Manager's Software library through the Enterprise Manager Cloud Control user interface. You can now use the following EMCLI command to upload multiple patches directly from a remote location within the data center: $emcli upload_patches -location <Path to Patch directory> -from_host <HOSTNAME> The upload process filters all of the new patches, automatically selects the relevant metadata files from the location, and uploads the patches to software library. Other Improvements:  Patch rollback for single instance databases, new option in the Patch Plan to rollback the patches added to the patch plans. Upon execution, the procedure would rollback the patch and the SQL applied to the single instance Databases. Improved and faster configuration collection of Oracle Home targets can enable more reliable automation at higher level functions like Provisioning, Patching or Database as a Service. Just to recap, here is a list of database lifecycle management features:  * Red highlights mark – New or Enhanced in the Release 3. • Discovery, inventory tracking and reporting • Database provisioning including o Migration to Pluggable databases o Plugging and unplugging of pluggable databases o Gold image based cloning o Scaling of RAC nodes •Schema and data change management •End-to-end patch management in online and offline modes, including o Patch advisories in online (connected with My Oracle Support) and offline mode o Patch pre-deployment analysis, deployment and rollback (currently only for single instance databases) o Reporting • Upgrade planning and execution of the upgrade process • Configuration management including • Compliance management with out-of-box content • Change Activity Planner for planning, designing and tracking long running processes For more information on Enterprise Manager’s database lifecycle management capabilities, visit http://www.oracle.com/technetwork/oem/lifecycle-mgmt/index.html

• Activist shared printing material gallery

  - by Dave

  What would you say would be the best way to do this: We would like to create a section on our activist community FB page and website in order to share with everyone images and files ready for printing panflets, brochures, t-shirts, stickers, etc. Let's say we have some cool slogans for t-shirts, so we would like to show them on a gallery, and offer for download the original design files needed for a print shop to create the t-shirts. And the same thing for all other kinds of media. We want to enable anyone to be able to just download the files for free, and easily create printed materials with them. But besides offering this hybrid between picture gallery and downloads manager, we would also like to make it very easy for anyone to upload and share their own files with the community, to make it a true collaboration initiative, be it that they get posted automatically, or that we first review and approve all uploads. Cafepress or Spreadshirt let you upload your design and sell your own merchandise. We need something similar, but where people can then download working files for making quality printings and materials. What apps, tools, services or methods are out there with which you think this could be best done?? We have some ideas, but we would like to hear some more!!

• How to Implement Complex Form Data?

  - by SoulBeaver

  I'm supposed to implement a relatively complex form that looks like follows, but has at least four more pages requiring the user to fill in all necessary information for the tracks: This data will need to be sent to the server, which is implemented using Dropwizard. I'm looking for best practices on how to upload and send such a complex form with potentially dozens of songs to the server. The simplest available solution I have seen is a simple multipart/form-data request with the following form schema (Source): Client <html> <body> <h1>File Upload with Jersey</h1> <form action="rest/file/upload" method="post" enctype="multipart/form-data"> <p> Select a file : <input type="file" name="file" size="45" /> </p> <input type="submit" value="Upload It" /> </form> </body> </html> Server @POST @Path("/upload") @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadTrack(final FormDataMultiPart multiPart) { List<FormDataBodyPart> artists = multiPart.getFields("artist"); StringBuffer output = new StringBuffer(); for (FormDataBodyPart artist : artists) output.append(artist.getValueAs(String.class)); List<FormDataBodyPart> tracks = multiPart.getFields("track"); for (FormDataBodyPart track : tracks) writeToFile(track.getValueAs(InputStream.class), "Foo"); return Response.status(200).entity(output.toString()).build(); } Then I have also read about file uploads via Ajax or Formdata (Mozilla HttpRequest) which allows for Posts in the formats application/x-www-form-urlencoded, multipart/form-data, or text/plain. I don't know which approach, if any, is best. An ideal solution would be to utilize Jackson to convert a json string into my data objects, but I don't get the impression that this is possible with binary data.

• Looking for someone to point me in the right direction. I want to learn how to use hosted servers

  - by Leisure

  TL;DR: I want a Java program to run on a server, I want the server to forward a particular port from external to internal IP, I want store a few files on the server. Guides please. So I made a hack job Java program that acts as a server for my android application. It stores data in text files and HTML files, uploads them via FTP to my webhost, and manages socket connections (using port forwarding) with any phones connected. Right now I'm running it on NetBeans on my home computer. I know that it will probably slow down or crash once about 50 phones are connected at once. Is there any way I can run this program on a server with a high bandwidth? Can someone please find me a guide for that? I'm noob and don't know where to start looking. I seriously don't know anything about renting or using servers - I need a nice guide, and recommendations. My requirements for the server: Can handle about 2k socket connections at once Can run my Java code and store my txt files Can give me a port and an IP address so TCP/IP clients can be connected My budget: $50 CAD per month. Please someone set my ship sailing in the right direction, I really don't know where to look for resources.

• How do I convince my boss that it's OK to use an application to access an outside website?

  - by Cyberherbalist

  That is, if you agree that it's OK. We have a need to maintain an accurate internal record of bank routing numbers, and my boss wants me to set up a process where once a week someone goes to the Federal Reserve's website, clicks on the link to get the list of routing numbers (or the link giving the updates since a particular date), and then manually uploads the resultant text file to an application that will make the update to our data. I told him that a manual process was not at all necessary, and that I could write a routine that would access the FED's routing numbers in the application that keeps our data updated, and put it on whatever schedule was appropriate. But he is greatly opposed to doing this, and calls it "hacking the Federal Reserve website." I think he's afraid that the FED is going to get after us. I showed him the FED's robot.txt file, and the only thing it forbids is an automated indexing of pages with extension .cf*: User-agent: * # applies to all robots Disallow: CF # disallow indexing of all CF* directories and pages This says nothing about accessing the same data automatically that you could access manually. Anyone have a good counterargument to the idea that we'd be "hacking" the FED?

• How do I backup my customer's data?

  - by marcamillion

  If you run a SaaS app, or work on one, I would love to hear from you. Where the safety and security of your customer's data is paramount, how do you secure it and back it up? I would love to know your main host (e.g. Heroku, Engine Yard, Rackspace, MediaTemple, etc.) and who you use for your backup. Be as detailed as possible - e.g. a quick overview of your service and the data you store (images for instance), what happens with the images when the user uploads them (e.g. they go to your Linode VPS, and posted to the site for them to see - then they are automatically sent to AWS or wherever, then once a week they are backed up to tape by the managed hosting provider, and you also back them up to your house/office). If you could also give some idea as to what the unit cost (per GB/per user/per month) of storage is - on average, I would really appreciate that. Getting ready to launch my app, and I would love to get some more perspective on the nitty gritty details involved. Thanks!

• Source code not matching uploaded HTML file

  - by benhowdle89

  I'm not sure if this is the right place to ask but i'm having a hugely frustrating problem with Coda and my website (i'm not sure which one is causing the issue) I'm using Coda to make changes to my website, Coda uses built in FTP to save changes to your web page. So when you hit Save, it uploads the new file. I've been using Coda for months and never had a problem until now. I am making changes in the html of my index.php and hitting save, it's successfully uploading the file but no changes are reflected in the source code in ANY browser. I even logged into cPanel on my website, ie. www.example.com:2082 and looked at the file - the changes have been made successfully. But the actual webpage in browser's source code, no changes?? I have tried adding which made no difference. Interestingly i make changes to style.css and the changes are instant. I have emptied the cache on all of my browsers but i'm still having an issue. Does this sound like a Coda problem or has anyone heard of such a thing?

• Service layer coupling

  - by Justin

  I am working on writing a service layer for an order system in php. It's the typical scenario, you have an Order that can have multiple Line Items. So lets say a request is received to store a line item with pictures and comments. I might receive a json request such as { 'type': 'Bike', 'color': 'Red', 'commentIds': [3193,3194] 'attachmentIds': [123,413] } My idea was to have a Service_LineItem_Bike class that knows how to take the json data and store an entity for a bike. My question is, the Service_LineItem class now needs to fetch comments and file attachments, and store the relationships. Service_LineItem seems like it should interact with a Service_Comment and a Service_FileUpload. Should instances of these two other services be instantiated and passed to the Service_LineItem constructor,or set by getters and setters? Dependency injection seems like the right solution, allowing a service access to a 'service fetching helper' seems wrong, and this should stay at the application level. I am using Doctrine 2 as a ORM, and I can technically write a dql query inside Service_LineItem to fetch the comments and file uploads necessary for the association, but this seems like it would have a tighter coupling, rather then leaving this up to the right service object.

• YouTube custom thumbnails feature availability

  - by skat

  I've been trying to figure out this on my own for weeks, but now I give up. 'Custom thumbnails' feature on YouTube is such a controversial one, it was changed so much... so much that even FAQ on YouTube doesn't fully describe it's features (as I see). I have a YouTube channel for one of my websites. This YouTube channel is main marketing force for my website - it brings all the boys to my yard (I mean, website). So I have to use all the hacky-tricky stuff to increase my visibility on youtube. And damn, those custom thumbnails are giving me hard times... As far as I understand, this is current state of 'custom thumbnail' feature: "If your account is in good standing, you may have the ability to upload custom thumbnails for your video uploads." (c) https://support.google.com/youtube/answer/138008 My channel has good standing, has more than 50000 views. So why the hell my account is still not eligible for this feature? anyone have any idea?

• Good podcasting solution?

  - by burnso

  I simply ask for the best, most common and simple way to set up a podcast? Please, I need an answer so I can close this question? I run a joomla-based website for a small church and now need a simple, cheap and effective solution for an audio podcast. I am looking for a solution that will do the following: User uploads audio files to service (preferably not to our own site) that is cheap, fast and simple to use. Dropbox for example? Files are easily embeddable into Joomla website articles to be played on the spot (through simple-to-use and media player). Preferably through RSS feeds (to make it easy to update every week). Files are downloadable. Files are viewable on iPhones and other smartphones. Solution can be broadcasted via iTunes. Solution doesn't need a lot of extra, new third party software. I'd rather keep it simple and familiar than have it be a complete new system but with a steep learning curve. At the moment we use vimeo to host the podcast, through video files. But we'd like to move to something simpler that doesn't involve a series of difficult steps to upload the files to the web.

• Why choose an established CMS as opposed to building one from scratch?

  - by SkonJeet

  A lot of my research over the next few weeks will be into different CMS's. I've already had a brief look at episerver and umbraco. While reading into these systems I can't help but think that providing content management features are achievable without learning the details and structure of many of these (rather large) CMS platforms. I have, in the past, been given projects whereby my role as a developer must be kept separate to that of an editor (makes sense). i.e. It was my task to develop the design and functionality of the site and my clients' job to update the content. I've achieved this by also implementing a sort of 'portal' on which there were a couple of pages that would accept text input and picture uploads etc. (basically, whatever content they wanted), record this new content to the database and then by design the code-behind would read all this from the database into relevant controls (repeaters for example). For me, this has been an effective enough way of my clients managing the content to deploy with my solutions. I know that I am wrong - and that CMS's are preferable to those that are built from the ground up - but other than the matter of cost, why?

• Problem with saving pictures in certain ways [migrated]

  - by user132750

  I am making a Garfield comic viewer in C#. I have a button that saves the comic on screen to the computer. However, when I compile it from Visual C# Express, it saves perfectly. When I run the exe file from the directory, I get an unhandled exception message stating "A generic error occurred in GDI+". Here is my saving code: private void save_Click(object sender, EventArgs e) { using (SaveFileDialog sfdlg = new SaveFileDialog()) { sfdlg.Title = "Save Dialog"; sfdlg.Filter = "Bitmap Images (*.bmp)|*.bmp|All files(*.*)|*.*"; if (sfdlg.ShowDialog(this) == DialogResult.OK) { using (Bitmap bmp = new Bitmap(pictureBox1.Image.Width, pictureBox1.Image.Height)) { pictureBox1.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height)); pictureBox1.Image = new Bitmap(pictureBox1.Image.Width, pictureBox1.Image.Height); pictureBox1.Image.Save("c://cc.Jpg"); bmp.Save(sfdlg.FileName); pictureBox1.ImageLocation = "http://garfield.com/uploads/strips" + "/" + whole.ToString("yyyy-MM-dd") + ".jpg"; MessageBox.Show("Comic Saved."); } } } } What can I do?

• Google Maps API vs Multimap/Bing Maps API

  - by mdresser

  I want to know if anyone who has experience of using both the Google Maps API and the Multimap API can give a good reason as to why one is better than the other - or maybe a list of pros and cons? I will be working on a complete re-development of a site which currently uses the Multimap (Classic) API and want to consider the possibility of using Google Maps API instead of Multimap (now MS Bing), but I need a compelling reason to justify this decision. The site currently provides a search mechanism allowing users to search for addresses using postcode/partial postcode or city. The current system has a sqlserver database back-end containing full address details and also uploads (geocodes this information to Multimap with a daily scheduled task). I'm wondering if it's possible with the Google API to avoid the need for the daily upload and just use it's geocoding API instead (though this is limited by Google's restriction of a certain number of geocoding requests per day).

• Silverlight Ftp Upload

  - by Curtis

  Hi I'm working on trying to ftp a file to the server through a silverlight application. Where the location to upload the file on server file system, exists outside the sandbox area for the web server. In this case the web server root exists at "C:\test\www\" and the location to upload the file will exist at "C:\User\Uploads". In this scenerio i'm not sure if Http POST will work (doesn't that use the web server root). I just need to upload the file selected by the user to a different location that may exist outside the sandbox. With silverlight i'm thinking sockets are my last option based on the limited port range for silverlight being 4502-4532. Can i do this using WebClient and Http POST? Can i make an ftp connection through silverlight or javascript?
