• Best Practice for Uploading Many (2000+) Images to A Server

  - by bob

  Hello, I have a general question about this. When you have a gallery, sometimes people need to upload 1000's of images at once. Most likely, it would be done through a .zip file. What is the best way to go about uploading this sort of thing to a server. Many times, server have timeouts etc. that need to be accounted for. I am wondering what kinds of things should I be looking out for and what is the best way to handle a large amount of images being uploaded. I'm guessing that you would allow a user to upload a zip file (assuming the timeout does not effect you), and this zip file is uploaded to a specific directory, lets assume in this case a directory is created for each user in the system. You would then unzip the directory on the server and scan the user's folder for any directories containing .jpg or .png or .gif files (etc.) and then import them into a table accordingly. I'm guessing labeled by folder name. What kind of server side troubles could I run into? I'm aware that there may be many issues. Even general ideas would be could so I can then research further. Thanks! Also, I would be programming in Ruby on Rails but I think this question applies accross any language.

• Gems install fine but don't show as installed under rake gems

  - by Josh Pinter

  I'll show you my output here: rake gems (in /Users/jp/Sites/central/trunk) - [F] authlogic - [R] activesupport - [F] builder - [F] formtastic - [R] activesupport >= 2.3.0 - [R] actionpack >= 2.3.0 - [ ] fastercsv I = Installed F = Frozen R = Framework (loaded before rails starts) Making sure fastercsv is installed: gem which fastercsv /usr/local/lib/ruby/gems/1.8/gems/fastercsv-1.5.3/lib/fastercsv.rb After installing through a variety of methods but only one is shown here: sudo rake gems:install (in /Users/jp/central/trunk) gem install fastercsv Successfully installed fastercsv-1.5.3 1 gem installed Installing ri documentation for fastercsv-1.5.3... Installing RDoc documentation for fastercsv-1.5.3... And try it again. rake gems (in /Users/jp/Sites/central/trunk) - [F] authlogic - [R] activesupport - [F] builder - [F] formtastic - [R] activesupport >= 2.3.0 - [R] actionpack >= 2.3.0 - [ ] fastercsv I = Installed F = Frozen R = Framework (loaded before rails starts) One thing to know is that I tried unpacking the gems but if it doesn't think it's installed it can't unpack it. Another thing is that I really tried to figure this out. There's a bunch of people saying clean up local gems in your user account, always install with sudo, etc. But I've tried all that. What would you guys do to fix this? Thanks many times over, Josh

• Image Wells, Core Data, and Sqlite files.

  - by Sway

  I've got a mac application that I've developed. I use it to create sqlite files that are bundled with my iphone app. The mac app uses Core Data and bindings and is working fine except for one "weird" issue. I use an NSImageView (or Image Well) to allow me to drag and drop jpg files. This is bound through to an optional binary attribute in my model class. For some reason when I drag and drop a 4k jpg file it onto the image well and save the sqlite file. The data saved to the binary column is over 15 times larger than it should be. Whereas if I use an application like SQLiteManager and add the image into the row in the database. The binary data is the correct (expected size). File 4k jpg Actual size: 2371. Persisted via Core Data size: 35810. Can anyone give me a suggestion as to why this might be happening? Do I need to set some setting in Interface Builder or write some custom code?

• Change UIButton Background Image more than once per second

  - by beta.services

  I am currently working with the iPhone SDK. I have a NSTimer that changes the background image of a UIButton. Once this is complete, it will trigger the same action again (reset the NSTimer) for a predetermined number of times. My problem is that if my NSTimer is set to execute more than once per second. (0.75, say) The background image wont change. I am using NSLog to check that the event fires. But the button image will just remain in its original state. Is there any way to change the background image more often than once per second? This is my timer : [NSTimer scheduledTimerWithTimeInterval: tmpLvlSpeed target: self selector: @selector(simPressRed:) userInfo: nil repeats: NO]; And the code to change the image: [btnRed setImage:[UIImage imageNamed:@"btn_red.png"] forState:UIControlStateNormal]; if tmpLvlSpeed is less than 1.0, the button image will never change. Even though the simPressRed function will still fire. Any clues? Is there an update cycle I can modify?

• Read a buffer of unknown size (Console input)

  - by Sanarothe

  Hi. I'm a little behind in my X86 Asm class, and the book is making me want to shoot myself in the face. The examples in the book are insufficient and, honestly, very frustrating because of their massive dependencies upon the author's link library, which I hate. I wanted to learn ASM, not how to call his freaking library, which calls more of his library. Anyway, I'm stuck on a lab that requires console input and output. So far, I've got this for my input: input PROC INVOKE ReadConsole, inputHandle, ADDR buffer, Buf - 2, ADDR bytesRead, 0 mov eax,OFFSET buffer Ret input EndP I need to use the input and output procedures multiple times, so I'm trying to make it abstract. I'm just not sure how to use the data that is set to eax here. My initial idea was to take that string array and manually crawl through it by adding 8 to the offset for each possible digit (Input is integer, and there's a little bit of processing) but this doesn't work out because I don't know how big the input actually is. So, how would you swap the string array into an integer that could be used? Full code: (Haven't done the integer logic or the instruction string output because I'm stuck here.) include c:/irvine/irvine32.inc .data inputHandle HANDLE ? outputHandle HANDLE ? buffer BYTE BufSize DUP(?),0,0 bytesRead DWORD ? str1 BYTE "Enter an integer:",0Dh, 0Ah str2 BYTE "Enter another integer:",0Dh, 0Ah str3 BYTE "The higher of the two integers is: " int1 WORD ? int2 WORD ? int3 WORD ? Buf = 80 .code main PROC call handle push str1 call output call input push str2 call output call input push str3 call output call input main EndP larger PROC Ret larger EndP output PROC INVOKE WriteConsole Ret output EndP handle PROC USES eax INVOKE GetStdHandle, STD_INPUT_HANDLE mov inputHandle,eax INVOKE GetStdHandle, STD_INPUT_HANDLE mov outputHandle,eax Ret handle EndP input PROC INVOKE ReadConsole, inputHandle, ADDR buffer, Buf - 2, ADDR bytesRead, 0 mov eax,OFFSET buffer Ret input EndP END main

• how to combine widget webapp framework with SEO-friendly CSS and JS files

  - by Ali

  Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

• Linq2sql code generator misbehaving

  - by Martin

  Sometime the linq2sql just makes its mind up about things. I've been pulling my hair for the past hours trying to work out what I'm doing differently from all the other times when I don't get ForeignKeyReferenceAlreadyHasValueException. Turns out that if (this._Activity.HasLoadedOrAssignedValue) { throw new System.Data.Linq.ForeignKeyReferenceAlreadyHasValueException(); } is present on my primary key in this particular table, and in no other. No matter what I do with the association, I've even tried deleting and dragging the thing back to the designer, it's still there and I'm sure it's not supposed to be. I know why, of course, but I don't know why, so to speak. A while back the association went the other way. Whereas I've left that era behind me, the code generator seems to exhibit phantom pains. The same phenomenon, is responsible for me having to change the namespace in the designer.cs everytime I make changes in the designer. I made the mistake of renaming my namespace and the code generator just doesn't get it. Somebody please help this poor boy out.

• Debugging strategy to find the cause of bad_alloc

  - by SalamiArmi

  I have a fairly serious bug in my program - occasional calls to new() throw a bad_alloc. From the documentation I can find on bad_alloc, it seems to be thrown for these reasons: When the computer runs out of memory (which definitely isn't happening, I have 4GB of RAM, program throws bad_alloc when using less than 5MB (checked in taskmanager) with nothing serious running in the background). If the memory becomes too fragmented to allocate new blocks (which, again, is unlikely - the largest sized block I ever allocate would be about 1KB, and that doesn't get done more than 100 times before the crash occurs). Based on these descriptions, I don't really have anywhere in which a bad_alloc could be thrown. However, the application I am running runs more than one thread, which could possibly be contributing to the problem. By testing all of the objects on a single thread, everything seems to be working smoothly. The only other thing that I can think of that is going on here could be some kind of race-condition caused by calling new() in more than one place at the same time, but I've tried adding mutexes to prevent that behaviour to no effect. Because the program is several hundred lines and I have no idea where the problem actually lies, I'm not sure of what, if any, code snippets to post. Instead, I was wondering if there were any tools that will help me test for this kind of thing, or if there are any general strategies that can help me with this problem. I'm using Microsoft Visual Studio 2008, with Poco for threading.

• CSS sliding-door buttons center alignment

  - by rochal

  Hi guys, I need help to align CSS buttons. I tried many different variations and I just cannot center my button the way I want. Firstly, have a look at this url: http://www.front-end-developer.net/cssbuttons/example.htm I'm using 2 images to form a button (this could be done on 1 image, but in this case we've got two). Everything works as expected as long as we apply float:left or float:right to the parent div element, to 'limit' width of the div and close it as soon as the content of the div ends. You can remove float:left from the button to see what I mean. But what about center positioned buttons? I cannot add float:left/right because I want align it in the middle. In theory, I could set { width:XXpx; margin:0 auto; } And I will get what you can see on this picture: But I don't know the length of the text inside. Having different translations my button can be very short, or 5 times that long. I also tried to use <span> instead of <div>, but unfortunately nested inline elements don't respect their padding correctly... And yes, I must use <a> inside, so buttons can be accessed by web crawlers. I'm really stuck on this one.

• How do I store complex objects in javascript?

  - by Colen

  Hello, I need to be able to store objects in javascript, and access them very quickly. For example, I have a list of vehicles, defined like so: { "name": "Jim's Ford Focus", "color": "white", isDamaged: true, wheels: 4 } { "name": "Bob's Suzuki Swift", "color": "green", isDamaged: false, wheels: 4 } { "name": "Alex's Harley Davidson", "color": "black", isDamaged: false, wheels: 2 } There will potentially be hundreds of these vehicle entries, which might be accessed thousands of times. I need to be able to access them as fast as possible, ideally in some useful way. For example, I could store the objects in an array. Then I could simply say vehicles[0] to get the Ford Focus entry, vehicles[1] to get the Suzuki Swift entry, etc. However, how do I know which entry is the Ford Focus? I want to simply ask "find me Jim's Ford Focus" and have the object returned to me, as fast as possible. For example, in another language, I might use a hash table, indexed by name. How can I do this in javascript? Or, is there a better way? Thanks.

• Can someone describe the nested set model from a C#/LINQ perspective?

  - by Chad

  I know the nested set model doesn't pertain to the C# language or LINQ directly... it's what I'm using to develop my web app. For hierarchical data (categories with sub-categories in my case), I'm currently using something similar to the Adjacency List model. At the moment, I've only got 2 levels of categories, but I'd like to take it further and allow for n levels of categories using the nested set model. I'm not quite clear on how to use it in a C# context. Here's the article I'm reading on the nested set model. Though this article cleared up my confusion some, I still have a big ?? in my head: - Is inserting, updating or deleting categories tedious? It looks like the left and right numbers would require re-numbering... what would the LINQ queries look like for the following scenarios? Delete a child node (re-number all node's left/right values) Delete a parent node (what do you do with the orphans?) Move a child node to a different parent node (renumber again) If my understanding is correct, at all times the child node's left/right values will always be between the parent node's left/right values, am I correct? Seems easy enough, if only the categories were static... most likely I need to spend more time to get my head around the concept. Any help is greatly appreciated!

• how to insert multiple rows using cakephp

  - by Paul

  In the cakePHP project I'm building, I want to insert a defined number of identical records. These will serve as placeholders records that will have additional data added later. Each record will insert the IDs taken from two belongs_to relationships as well as two other string values. What I want to do is be able to enter a value for the number of records I want created, which would equate to how many times the data is looped during save. What I don't know is: 1) how to setup a loop to handle a set number of inserts 2) how to define a form field in cakePHP that only sets the number of records to create. What I've tried is the following: function massAdd() { $inserts_required = 1; while ($inserts_required <= 10) { $this->Match->create(); $this->Match->save($this->data); echo $inserts_required++; } $brackets = $this->Match->Bracket->find('list'); $this->set(compact('brackets')); } What happens is: 1) at the top of the screen, above the doc type, the string 12345678910 is displayed, this is displayed on screen 2) a total of 11 records are created, and only the last record has the values passed in the form. I don't know why 11 records as opposed to 10 are created, and why only the last records has the entered form data? As always, your help and direction is appreciated. -Paul

• Does "for" in .Net Framework 4.0 execute loops in parallel? Or why is the total not the sum of the p

  - by Shiraz Bhaiji

  I am writing code to performance test a web site. I have the following code: string url = "http://xxxxxx"; System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch(); System.Diagnostics.Stopwatch totalTime = new System.Diagnostics.Stopwatch(); totalTime.Start(); for (int i = 0; i < 10; i++) { stopwatch.Start(); WebRequest request = HttpWebRequest.Create(url); WebResponse webResponse = request.GetResponse(); webResponse.Close(); stopwatch.Stop(); textBox1.Text += "Time Taken " + i.ToString() + " = " + stopwatch.Elapsed.Milliseconds.ToString() + Environment.NewLine; stopwatch.Reset(); } totalTime.Stop(); textBox1.Text += "Total Time Taken = " + totalTime.Elapsed.Milliseconds.ToString() + Environment.NewLine; Which is giving the following result: Time Taken 0 = 88 Time Taken 1 = 161 Time Taken 2 = 218 Time Taken 3 = 417 Time Taken 4 = 236 Time Taken 5 = 217 Time Taken 6 = 217 Time Taken 7 = 218 Time Taken 8 = 409 Time Taken 9 = 48 Total Time Taken = 257 I had expected the total time to be the sum of the individual times. Can anybody see why it is not?

• OpenGL - drawing 2D polygons shapes with texture

  - by plonkplonk

  I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

• UIView coordinate transforms on rotation during keyboard appearance

  - by SG

  iPad app; I'm trying to resize my view when the keyboard appears. It amounts to calling this code at appropriate times: CGRect adjustedFrame = self.frame; adjustedFrame.size.height -= keyboardFrame.size.height; [self setFrame:adjustedFrame]; Using this technique for a view contained in a uisplitview-based app works in all 4 orientations, but I've since discovered that a vanilla uiview-based app does not work. What happens is that apparently the uisplitview is smart enough to convert the coordinates of its subviews (their frame) such that the origin is in the "viewer's top left" regardless of the orientation. However, a uiview is not able to correctly report these coordinates. Though the origin is reported as (0,0) in all orientations, the view's effective origin is always as if the ipad were upright. What is weird about this is that the view correctly rotates and draws, but it always originates in the literal device top left. How can I get the view to correctly make its origin the "top left" to the viewer, not the device's fixed top left? What am I missing? Please, for something so trivial I've spent about 6 hours on this already with every brute force technique and research angle I could think of. This is the original source which doesn't work in this case: http://stackoverflow.com/questions/1951826/move-up-uitoolbar

• Speed of CSS

  - by Ólafur Waage

  This is just a question to help me understand CSS rendering better. Lets say we have a million lines of this. <div class="first"> <div class="second"> <span class="third">Hello World</span> </div> </div> Which would be the fastest way to change the font of Hello World to red? .third { color: red; } div.third { color: red; } div.second div.third { color: red; } div.first div.second div.third { color: red; } Also, what if there was at tag in the middle that had a unique id of "foo". Which one of the CSS methods above would be the fastest. I know why these methods are used etc, im just trying to grasp better the rendering technique of the browsers and i have no idea how to make a test that times it. UPDATE: Nice answer Gumbo. From the looks of it then it would be quicker in a regular site to do the full definition of a tag. Since it finds the parents and narrows the search for every parent found. That could be bad in the sense you'd have a pretty large CSS file though.

• JQuery-UI Drag, Drop and Re-Drag Clones on Re-Drag

  - by amarcy

  I am using the following code to extend the JQuery-UI demos included with the download. I am trying to set up a container that the user can drag items into and then move the items around within the container. I incorporated the answer from http://stackoverflow.com/questions/867469/jquery-draggable-clone which works with one problem. <script> $(document).ready(function() { $("#droppable").droppable({ accept: '.ui-widget-content', drop: function(event, ui) { if($(ui).parent(":not(:has(#id1))")){ $(this).append($(ui.helper).clone().attr("id", "id1")); } $("#id1").draggable({ containment: 'parent', }); } }); $(".ui-widget-content").draggable({helper: 'clone'}); }); </script> div class="demo"> <div id="draggable" class="ui-widget-content"> <p>Drag me around</p> </div> <div id="droppable" class="ui-widget-header"> <p>Drop here</p> </div> When an item is dropped onto the droppable container it can be dragged one time and when it is dropped after that drag it loses its dragging capability. How do I allow for the item to be dragged multiple times after it has been added to the droppable container?

• Application doesn't exit with 0 threads

  - by Bryce Wagner

  We have a WinForms desktop application, which is heavily multithreaded. 3 threads run with Application.Run and a bunch of other background worker threads. Getting all the threads to shut down properly was kind of tricky, but I thought I finally got it right. But when we actually deployed the application, users started experiencing the application not exiting. There's a System.Threading.Mutex to prevent them from running the app multiple times, so they have to go into task manager and kill the old one before they can run it again. Every thread gets a Thread.Join before the main thread exits, and I added logging to each thread I spawn. According to the log, every single thread that starts also exits, and the main thread also exits. Even stranger, running SysInternals ProcessExplorer show all the threads disappear when the application exits. As in, there are 0 threads (managed or unmanaged), but the process is still running. I can't reproduce this on any developers computers or our test environment, and so far I've only seen it happen on Windows XP (not Vista or Windows 7 or any Windows Server). How can a process keep running with 0 threads?

• JQuery Validation Plugin: Prevent validation issue on nested form

  - by Majid

  I have a form on which I use validation. This form has a section for photo upload. Initially this section contains six elements with the following code: <img class="photo_upload" src="image/app/photo_upload.jpg"> I have bound a function to the click event for the class of photo_upload. This function replaces the image with a minimal form with this code: Copy code <form onsubmit="startUploadImage();" target="control_target" enctype="multipart/form-data" method="post" action="index.php"> <input type="hidden" value="add_image" name="service"> <input type="hidden" value="1000000" name="MAX_FILE_SIZE"> <input type="file" size="10" name="photo" id="photo_file_upload"><br> <button onclick="javascript:cancel_photo_upload();return false;">Cancel</button> </form> So, essentially, after the image is clicked, I'd have a new form nested in my original, validated form. Now, when I use this new form and upload an image, I receive an error (repeated three times) saying: validator is undefined http://host.com/path/index.php Line 286 What is going on here? My guess is this Submit event bubbles up to the outer form As we have validation on that form, validation is triggered, Validation tries to find the form triggering it, Since we have not bound validation to the inner form it returns 'undefined' Now, is my assessment correct? Whether it is or not, how can I solve this issue?

• HttpWebRequest Timeouts After Ten Consecutive Requests

  - by Bob Mc

  I'm writing a web crawler for a specific site. The application is a VB.Net Windows Forms application that is not using multiple threads - each web request is consecutive. However, after ten successful page retrievals every successive request times out. I have reviewed the similar questions already posted here on SO, and have implemented the recommended techniques into my GetPage routine, shown below: Public Function GetPage(ByVal url As String) As String Dim result As String = String.Empty Dim uri As New Uri(url) Dim sp As ServicePoint = ServicePointManager.FindServicePoint(uri) sp.ConnectionLimit = 100 Dim request As HttpWebRequest = WebRequest.Create(uri) request.KeepAlive = False request.Timeout = 15000 Try Using response As HttpWebResponse = DirectCast(request.GetResponse, HttpWebResponse) Using dataStream As Stream = response.GetResponseStream() Using reader As New StreamReader(dataStream) If response.StatusCode <> HttpStatusCode.OK Then Throw New Exception("Got response status code: " + response.StatusCode) End If result = reader.ReadToEnd() End Using End Using response.Close() End Using Catch ex As Exception Dim msg As String = "Error reading page """ & url & """. " & ex.Message Logger.LogMessage(msg, LogOutputLevel.Diagnostics) End Try Return result End Function Have I missed something? Am I not closing or disposing of an object that should be? It seems strange that it always happens after ten consecutive requests. Notes: In the constructor for the class in which this method resides I have the following: ServicePointManager.DefaultConnectionLimit = 100 If I set KeepAlive to true, the timeouts begin after five requests. All the requests are for pages in the same domain. EDIT I added a delay between each web request of between two and seven seconds so that I do not appear to be "hammering" the site or attempting a DOS attack. However, the problem still occurs.

• What is the fastest, most efficient way to get up to speed on a new technology?

  - by SLC

  My current job involves working with a huge number of technologies, most of which are very niche and unheard of. In some cases I have to write something about the technology, or with the technology, such as some lessons, examples, or tutorials, on behalf of the developer of that technology or someone that is backing it. When I get told to learn about a new technology, my first port of call is to check our internal library, and then look on amazon for a book on the subject. Failing that, or if the project is too small to warrant a purchase, I hit up google and youtube. However the results of randomly googling what I want to learn are hit and miss. Some days, I can find everything I want to know in a series of lessons or videos, and it's no problem. Other times, I can find almost nothing, and I really have to piece together things from sites. The result is that there are various resources out there, videos, interactive lessons, tutorials, books etc. but when I need to learn something fast, I often don't know the best way to go about it. It's not about fun, because I don't always have the luxury of working my way through a 600 page textbook named "A Complete Guide To Technology X", I have to deliver results quickly. One of the examples I'd like to use is ASP.NET MVC 2 which is something I have been told to learn. I grabbed a book on MVC 1 to refresh my knowledge, but googling it does't produce much useful information. I've seen a ton of ScottGu's tutorials on it, but they are mostly feature presentations, and some date back almost a year. The same applies to channel 9 and there are no books out yet on amazon. My question therefore has two parts, the first asks, "Where are the best places to look to get the information needed to learn a new technology?" and the second asks "What is the most efficient way to use such resources to learn a new technology?"

• Suggest joomla html editor extension/software

  - by DMin

  I've started using Joomla 1.5 recently and am using the TinyMCE online WYSIWYG editor that comes with the package to edit articles. I tend to write direct html and javascript rather than use the WYSIWYG functions, I find that after the first time the changes are applied(page updated) most of your html becomes 4-5 separate big paragraphs. Its very hard to find stuff in there cause the content has no formatting -- eg: <p><span id="psy_ass_span" class="pink_heading">Psychometric Assessment</span></p> <div id="psy_ass_div" class="pink_box"><img class="img_right" src="templates/teamwork.jpg" border="0" /> <p><strong>Emporkommen</strong> uses <strong>Psychometric assessment</strong> as a tool in order to gain insight into a person’s personality and psychological thinking. It can help develop team spirit in t <script src="plugins/editors/tinymce/jscripts/tiny_mce/themes/advanced/langs/en.js" type="text/javascript"></script> he workplace and assess an individual’s priorities.</p> Plus obviously there is no code highlighting in the editor so you can't figure out what is what. My question is, do you guys know of good(preferably non-commercial) extensions or other softwares or techniques that can make editing html code in Joomla 1.5 articles easier even after applying changes several times.

  Hi, i'm new to java and i got some problems. i'm developping a web application using the framework stripes on tomcat 6.0. I'm working with eclipse EE on windows. i successfully managed to get the stripes example application (called Bugzooky) up and running on my tomcat server. I imported the .war file and stripes libs in Eclipse. Here is the stripes archive containing the examples and libs But now i'm trying to change the example source files to learn how does it work. but whatever the modification made to the source files "WebContent/WEB-INF/src/*.java", nothing change! even after restarting the server. i noticed that the classes are compiled into .class files in the "ImportedClasses" folder, and tomcat always use these files, they are never updated, and if i removed one of them, the application just don't start. it look like my source files don't exists! I also tried to build my webapp from scratch, but when i tried to use the features used in the example files (like SecurityFilter.java): import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import ... It ends up with plenty of: the import javax.servlet.Filter cannot be resolved I checked the Librairies and it look like i'm using exactly the same as the example. It's probably something i didn't understood about java but i googled 100 times yesterday, and i can't find the solution (i probably didn't search the right place because i don't really understand my problem). I hope you'll be able to help me.

• Open source file upload with no timeout on IIS6 with ASP, ASP.NET 2.0 or PHP5

  - by Christopher Done

  I'm after a cross-platform cross-browser way of uploading files such that there is no timeout. Uploads aren't necessarily huge -- some just take a long time to upload because of the uploader's slow connection -- but the server times out anyway. I hear that there are methods to upload files in chunks so that somehow the server decides not to timeout the upload. After searching around all I can see is proprietary upload helpers and Java and Flash (SWFUpload) widgets that aren't cross-platform, don't upload in chunks, or aren't free. I'd like a way to do it in any of these platforms (ASP, ASP.NET 2.0 or PHP5), though I am not very clued up on all this .NET class/controller/project/module/visual studio/compile/etc stuff, so some kind of runnable complete project that runs on .NET 2.0 would be helpful. PHP and ASP I can assume will be more straight-forward. Unless I am completely missing something, which I suspect/hope I am, reasonable web uploads are bloody hard work in any language or platform. So my question is: how can I perform web browser uploads, cross-platform, so that they don't timeout, using free software? Is it possible at all?

• How does initializing inherited members inside base class constructor reduce the calls to…?

  - by flockofcode

  I’ve read that instead of initializing inherited members ( _c1 in our example ) inside derived constructor: class A { public int _c; } class B:A { public B(int c) { _c = c; } } we should initialize them inside base class constructor, since that way we reduce the calls to inherited members ( _c ): class A { public A(int c) { _c = c; } public int _c; } class B:A { public B(int c) : base(c) { } } If _c field is initialized inside base constructor, the order of initialization is the following: 1) First the field initializers of derived class B are called 2) Then field initializers of base class A are called (at this point _c is set to value 0) 3) B’s constructor is called, which in turn calls A’s custom constructor 4) _c field gets set to value of a parameter c ( inside A’s custom constructor ) 5) Once A’s custom constructor returns, B’s constructor executes its code. If _c field is initialized inside B's constructor, the order of initialization is the following: 1) First the field initializers of a derived class B are called 2) Then field initializers of a base class A are called(at this point _c is set to value 0) 3) B’s constructor is called, which in turn calls A’s default constructor 4) Once A’s custom constructor returns, B’s constructor sets _c field to a value of parameter c As far as I can tell, in both cases was _c called two times, so how exactly did we reduce calls to inherited member _c? thanx
