• Practiaal rules for Django MiddleWare ordering?

  - by o_O Tync

  The official documentation is a bit messy: 'before' & 'after' are used for ordering MiddleWare in a tuple, but in some places 'before'&'after' refers to request-response phases. Also, 'should be first/last' are mixed and it's not clear which one to use as 'first'. I do understand the difference.. however it seems to complicated for a newbie in Django. Can you suggest some correct ordering for builtin MiddleWare classes (assuming we enable all of them) and — most importantly — explain WHY one goes before/after other ones? here's the list, with the info from docs I managed to find: UpdateCacheMiddleware Before those that modify 'Vary:' SessionMiddleware, GZipMiddleware, LocaleMiddleware GZipMiddleware Before any MW that may change or use the response body After UpdateCacheMiddleware: Modifies 'Vary:' ConditionalGetMiddleware Before CommonMiddleware: uses its 'Etag:' header when USE_ETAGS=True SessionMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' Before TransactionMiddleware: we don't need transactions here LocaleMiddleware, One of the topmost, after SessionMiddleware, CacheMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' After SessionMiddleware: uses session data CommonMiddleware Before any MW that may change the response (it calculates ETags) After GZipMiddleware so it won't calculate an E-Tag on gzipped contents Close to the top: it redirects when APPEND_SLASH or PREPEND_WWW CsrfViewMiddleware AuthenticationMiddleware After SessionMiddleware: uses session storage MessageMiddleware After SessionMiddleware: can use Session-based storage XViewMiddleware TransactionMiddleware After MWs that use DB: SessionMiddleware (configurable to use DB) All *CacheMiddleWare is not affected (as an exception: uses own DB cursor) FetchFromCacheMiddleware After those those that modify 'Vary:' if uses them to pick a value for cache hash-key After AuthenticationMiddleware so it's possible to use CACHE_MIDDLEWARE_ANONYMOUS_ONLY FlatpageFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) RedirectFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) (I will add suggestions to this list to collect all of them in one place)

• CSS Background image in Redmine template arbitrarily not loading

  - by Pekka

  I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg) background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading. Say you reload ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there. Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to look. Apache's, Mongrel's and Redmine's error logs look fine, though.

• Png image processing in .NET.

  - by Oybek

  I have the following task. Take a base image and overlay on it another one. The base image is 8b png as well as overlay. Here are the base (left) and overlay (right) images. Here is a result and how it must look. The picture in the left is a screenshot when one picture is on top of another (html and positioning) and the second is the result of programmatic merging. As you can see in the screenshot the borders of the text is darker. Also here are the sizes of the images Base image 14.9 KB Overlay image 6.87 KB Result image 34.8 KB The size of the resulting image is also huge Here is my code that I use to merge those pictures /*...*/ public Stream Concatinate(Stream baseStream, params Stream[] overlayStreams) { var @base = Image.FromStream(baseStream); var canvas = new Bitmap(@base.Width, @base.Height); using (var g = canvas.ToGraphics()) { g.DrawImage(@base, 0, 0); foreach (var item in overlayStreams) { using (var overlayImage = Image.FromStream(item)) { try { Overlay(@base, overlayImage, g); } catch { } } } } var ms = new MemoryStream(); canvas.Save(ms, ImageFormat.Png); canvas.Dispose(); @base.Dispose(); return ms; } /*...*/ /*Tograpics extension*/ public static Graphics ToGraphics(this Image image, CompositingQuality compositingQuality = CompositingQuality.HighQuality, SmoothingMode smoothingMode = SmoothingMode.HighQuality, InterpolationMode interpolationMode = InterpolationMode.HighQualityBicubic) { var g = Graphics.FromImage(image); g.CompositingQuality = compositingQuality; g.SmoothingMode = smoothingMode; g.InterpolationMode = interpolationMode; return g; } My questions are What should I do in order to merge images to achieve the result as in the screenshot? How can I lower the size of the result image? Is the System.Drawing a suitable tool for this or is there any better tool for working with png for .NET?

• ExecutorService memory leak on exception

  - by TofuBeer

  I am having a hard time tracking this down since the profiler keeps crashing (hotspot error). Before I go too deep into figuring it out I'd like to know if I really have a problem or not :-) I have a few thread pools created via: Executors.newFixedThreadPool(10); The threads connect to different web sites and, on occasion, I get connection refused and wind up throwing an exception. When I later on call Future.get() to get the result it will then catch the ExecutionException that wraps the exception that was thrown when the connection could not be made. The program uses a fairly constant amount of memory up until the point in time that the exceptions get thrown (they tend to happen in batches when a particular site is overloaded). After that point the memory again remains constant but at a higher level. So my question is along the lines of is the memory behaviour (reported by "top" on Unix) expected because the exceptions just triggered something or do I probably have an actual leak that I'll need to track down? Additionally when Future.get() throws an exception is there anything else I need to do besides catch the exception (such as call Future.cancel() on it)?

• Advantage Database Server ORDER BY behaviour

  - by ie

  I'm using ADS v10 beta. I'm trying to numerate ordered resultset. 1) ORDER BY in nested queries. I need to use nested SELECT for some calculations: SELECT Name, Value, ROWNUM() FROM (SELECT * FROM MainTable WHERE Value > 0 ORDER BY Value) a And I'm getting Expected lexical element not found: ) There was a problem parsing the table names after the FROM keyword in your SELECT statement. Everything is working well when the ORDER BY is removed. Although, I found the sample in the Help, it looks like my query (more complex, indeed): SELECT * FROM (SELECT TOP 10 empid, fullname FROM branch1 ORDER BY empid) a UNION SELECT empid, fullname FROM branch2 ORDER BY empid 2) ORDER BY + ROWNUM(). I used the nested query in the example above, to numerate ordered rows. Is there are any chance to avoid nested query? In the SQL Server I can do something like this: SELECT Name, Value, ROW_NUMBER() OVER(ORDER BY Value) FROM MainTable WHERE Value > 1 ORDER BY Value Please advice. Thanks.

• Applications result affected by another running application.

  - by Jamie Keeling

  This is a follow on from my previous question although this is about something else. I've been having a problem where for some reason my message that I pass from one process to another only displays the first letter, in this case "M". My application is based on a MSDN sample so to make sure I hadn't missed something I create a separate solution, added the MSDN sample (without any changes for my needs) and unsurprisingly it works fine. Now for the weird bit, when I run the MSDN sample running (as in debugging) and have my own application running, the text prints out fine without any problems. The second I run my on its own without the original MSDN sample being open, and it fails to work and only shows an "M". I've looked in the debugger and don't seem to notice anything suspicious (it's a slightly dated picture, I've fixed the data type inconsistency). Can anyone provide a solution for this? I've never encountered anything like this before. To look at my source code it's easier to just look at the link I posted at the top of the question, there's no point in me posting it twice. Thank you for any help.

• L10N: Trusted test data for Locale Specific Sorting

  - by Chris Betti

  I'm working on an internationalized database application that supports multiple locales in a single instance. When international users sort data in the applications built on top of the database, the database theoretically sorts the data using a collation appropriate to the locale associated with the data the user is viewing. I'm trying to find sorted lists of words that meet two criteria: the sorted order follows the collation rules for the locale the words listed will allow me to exercise most / all of the specific collation rules for the locale I'm having trouble finding such trusted test data. Are such sort-testing datasets currently available, and if so, what / where are they? "words.en.txt" is an example text file containing American English text: Andrew Brian Chris Zachary I am planning on loading the list of words into my database in randomized order, and checking to see if sorting the list conforms to the original input. Because I am not fluent in any language other than English, I do not know how to create sample datasets like the following sample one in French (call it "words.fr.txt"): cote côte coté côté The French prefer diacritical marks to be ordered right to left. If you sorted that using code-point order, it likely comes out like this (which is an incorrect collation): cote coté côte côté Thank you for the help, Chris

• Allow paste in worksheet without overwriting locked cells

  - by jjeaton

  I have a protected worksheet that users would like to copy and paste into. I have no control over the workbook they are copying from. The protected worksheet has some rows that are available for data entry, and other rows that are locked and greyed out to the user. The users would like to be able to paste over the top of the entire worksheet from another random workbook and have all the cells available for data entry filled in, while the locked cells are undisturbed. In the current state, the user gets an error when they try to paste, because it cannot paste over the locked cells. Example: Worksheet 1: Act1 100 100 100 Act2 100 100 100 Act3 100 100 100 Worksheet 2: (The second row is locked) Act1 300 300 300 Act2 200 200 200 Act3 100 100 100 After copying/pasting Worksheet 2 should look like this: Act1 100 100 100 Act2 200 200 200 Act3 100 100 100 The values from worksheet 1 are populated and the locked rows are undisturbed. I've been thinking along the lines of having a hook where on paste, the locked cells are unlocked so that the paste can happen, and then are reverted to their original values and relocked. Is there some way I can loop through the cells in the clipboard and only paste cells where the target isn't locked? It is preferable to not create a separate button for paste, so there is less impact on the users, but if that's the only way, I'm not opposed to it. Currently, I plan on grouping the locked rows together, so that the data entry cells are contiguous, but then the accounts will be out of order, which is not preferred.

• How to get rid of gap when I add my custom UIViewController to window?

  - by wgpubs

  I'm getting this gap at the bottom of my window after I add the view of a custom UIViewController. The gap goes away as the view is shifted down after I move to another view and then back. Here is the code in the app delegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch CustomViewController *gvc = [[CustomViewController alloc] init]; self.customViewController = gvc; [gvc release]; [window addSubview:customViewController.view]; [window makeKeyAndVisible]; } "CustomViewController" is used as a root view controller to simply coordinate which other UIViewControllers to display. As such I simply set its view = to that of the first ViewController's view needed like so: - (void)loadView { UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; self.view = v; [v release]; // Add the HomeViewController to the top of the stack MainViewController *mvc = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; mvc.delegate = self; self.mainViewController = mvc; [mvc release]; [self.view addSubview:self.mainViewController.view]; } I've tried a bunch of things including what you see here with no luck. Any ideas? thanks

• sql-server performance optimization by removing print statements

  - by AG

  We're going through a round of sql-server stored procedure optimizations. The one recommendation we've found that clearly applies for us is 'SET NOCOUNT ON' at the top of each procedure. (Yes, I've seen the posts that point out issues with this depending on what client objects you run the stored procedures from but these are not issues for us.) So now I'm just trying to add in a bit of common sense. If the benefit of SET NOCOUNT ON is simply to reduce network traffic by some small amount every time, wouldn't it also make sense to turn off all the PRINT statements we have in the stored procedures that we only use for debugging? I can't see how it can hurt performance. OTOH, it's a bit of a hassle to implement due to the fact that some of the print statements are the only thing within else clauses, so you can't just always comment out the one line and be done. The change carries some amount of risk so I don't want to do it if it isn't going to actually help. But I don't see eliminating print statements mentioned anywhere in articles on optimization. Is that because it is so obvious no one bothers to mention it?

• How-to display a .gif as background image?

  - by Vito De Tullio

  Hi! I have a javascript "loading" function like this: function splashScreen() { var div = document.createElement('div'); div.appendChild(document.createTextNode("some text")); div.setAttribute("style", "position: fixed; " + "width: 100%; height: 100%; " + "left: 0; top: 0; " + "z-index: 1000; " + "background: #fff url('img/loading.gif') no-repeat center; " + "font-size: x-large; " + "text-align: center; " + "line-height: 3em; " + "opacity: 0.75; " + "filter: alpha(opacity=75); "); document.getElementsByTagName('body')[0].appendChild(div); return true; } I use this function in the form action (onsubmit="return splashScreen()") to show a "rotating logo" while the next page load... The problem is in that "img/loading.gif" and safari (on winXP): in ff and ie I have no problems, and I clearly see the animated gif. In safari I can't see it. If I change the image with a (obviously static) png the image appears... Am I doing something wrong? What's the problem with safari?

• Compiling gstreamer plugin in windows

  - by utnapistim

  Hello all, My question: What is the correct way to compile a gstreamer plugin in windows, so that it will be accepted by gstreamer (actually Songbird on top of gstreamer). My setup: I have downloaded the songbird sources following the steps described here and I have a trunk/dependencies/windows-i686-msvc8 directory within my svn sources with all the gstreamer binaries. I have created a gstreamer empty plugin skeleton following the steps detailed in the GStreamer Plugin Writer's Guide, and compiled it against the gstreamer binaries in the Songbird dependencies folder. The compilation was done with VS2010 RC1 (Visual Studio 2008 yelded the same results), using an empty DLL project with the .h and .c files generated using the GStreamer Plugin Writer's Guide. The DLL was lined with libcpmt.lib, libcmt.lib, ws2_32.lib, gobject-2.0.lib, gthread-2.0.lib, gstreamer-0.10-0.lib, glib-2.0.lib, kernel32.lib, nspr4.lib and ignoring all default libraries. I have compiled the files as both .c and .cpp with the same results. Testing: I have installed the Songbird binaries corresponding to the correct svn version, then installed Songbird Developer Tools addon and used it to create an addon for testing my gstreamer plugin. Songbird will not load the pluggin. I have also tried to load it with gst-launch.exe from the trunk/dependencies/windows-i686-msvc8/[...] directory and that generated runtime error R6034: An application has made an attempt to load the C runtime library incorrectly. Most resources I found for this problem recommended restarting or reinstalling windows :(.

• Seed has_many relation using mass assignment

  - by rnd

  Here are my two models: class Article < ActiveRecord::Base attr_accessible :content has_many :comments end class Comment < ActiveRecord::Base attr_accessible :content belongs_to :article end And I'm trying to seed the database in seed.rb using this code: Article.create( [{ content: "Hi! This is my first article!", comments: [{content: "It sucks"}, {content: "Best article ever!"}] }], without_protection: true) However rake db:seed gives me the following error message: rake aborted! Comment(#28467560) expected, got Hash(#13868840) Tasks: TOP => db:seed (See full trace by running task with --trace) It is possible to seed the database like this? If yes a follow-up question: I've searched some and it seems that to do this kind of (nested?) mass assignment I need to add 'accepts_nested_attributes_for' for the attributes I want to assign. (Possibly something like 'accepts_nested_attributes_for :article' for the Comment model) Is there a way to allow this similar to the 'without_protection: true'? Because I only want to accept this kind of mass assignment when seeding the database.

• Virus on site but can't find where

  - by Rob

  WARNING! THIS IS ABOUT A VIRUS ON MY SITE. IT APPEARS IT HAS BEEN THERE FOR SOMETIME AND I'VE HAD NO PROBLEMS. BUT PLEASE BE CAREFUL. READ EVERYTHING I SAY AND SEE IF YOU CAN HELP ME WITHOUT VISITING THE LINK. AVG PICKS UP ON IT AND BLOCKS IT, MCAFEE DOES NOT. Sorry about the warning, obviously i'm not here to get anyone infected or anything like that. Basically I run the website sortitoutsi dot net. Ages ago I got a virus on my computer, they got hold of my FTP passwords and added some lines of javascript to the top of my site. I removed them and believe it was fixed. However i'm using the "Web Developer" extension for Firefox and chose to view all javascript on my page and find there are various links to horrible urls such as: gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/aboutus.org/aboutus.org/google.com/skycn.com/torrents.ru.php and gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/index.php?jl= These terms do not appear anywhere. In the source code, in any of the javascript or the css. I also can't see that there are any rogue images that I don't recognise either. So i've no idea where this javascript is coming from. Can anyone suggest how I can find references to these links and remove them? I can see them both in the Web Developer firefox extension and in the net tab using Firebug. Any help would be greatly appreciated

• Display a ranking grid for game : optimization of left outer join and find a player

  - by Jerome C.

  Hello, I want to do a ranking grid. I have a table with different values indexed by a key: Table SimpleValue : key varchar, value int, playerId int I have a player which have several SimpleValue. Table Player: id int, nickname varchar Now imagine these records: SimpleValue: Key value playerId for 1 1 int 2 1 agi 2 1 lvl 5 1 for 6 2 int 3 2 agi 1 2 lvl 4 2 Player: id nickname 1 Bob 2 John I want to display a rank of these players on various SimpleValue. Something like: nickname for lvl Bob 1 5 John 6 4 For the moment I generate an sql query based on which SimpleValue key you want to display and on which SimpleValue key you want to order players. eg: I want to display 'lvl' and 'for' of each player and order them on the 'lvl' The generated query is: SELECT p.nickname as nickname, v1.value as lvl, v2.value as for FROM Player p LEFT OUTER JOIN SimpleValue v1 ON p.id=v1.playerId and v1.key = 'lvl' LEFT OUTER JOIN SimpleValue v2 ON p.id=v2.playerId and v2.key = 'for' ORDER BY v1.value This query runs perfectly. BUT if I want to display 10 different values, it generates 10 'left outer join'. Is there a way to simplify this query ? I've got a second question: Is there a way to display a portion of this ranking. Imagine I've 1000 players and I want to display TOP 10, I use the LIMIT keyword. Now I want to display the rank of the player Bob which is 326/1000 and I want to display 5 rank player above and below (so from 321 to 331 position). How can I achieve it ? thanks.

• How do you refactor a large messy codebase?

  - by Ricket

  I have a big mess of code. Admittedly, I wrote it myself - a year ago. It's not well commented but it's not very complicated either, so I can understand it -- just not well enough to know where to start as far as refactoring it. I violated every rule that I have read about over the past year. There are classes with multiple responsibilities, there are indirect accesses (I forget the technical term - something like foo.bar.doSomething()), and like I said it is not well commented. On top of that, it's the beginnings of a game, so the graphics is coupled with the data, or the places where I tried to decouple graphics and data, I made the data public in order for the graphics to be able to access the data it needs... It's a huge mess! Where do I start? How would you start on something like this? My current approach is to take variables and switch them to private and then refactor the pieces that break, but that doesn't seem to be enough. Please suggest other strategies for wading through this mess and turning it into something clean so that I can continue where I left off!

• Rails - CSV export: prompt for file download

  Hello, I want to give my users the ability to export a table to CSV. So in my controller, I've added on top of the file: respond_to :html, :js, :csv I'm also setting the headers if the requested format is csv: if params[:format] == 'csv' generate_csv_headers("negotiations-#{Time.now.strftime("%Y%m%d")}") end Code for generate_csv_headers(in application_controller) is: def generate_csv_headers(filename) headers.merge!({ 'Cache-Control' => 'must-revalidate, post-check=0, pre-check=0', 'Content-Type' => 'text/csv', 'Content-Disposition' => "attachment; filename=\"#{filename}\"", 'Content-Transfer-Encoding' => 'binary' }) end I've also created a view named index.csv.erb to generate my file: <%- headers = ["Id", "Name"] -%> <%= CSV.generate_line headers %> <%- @negotiations.each do |n| -%> <%- row = [ n.id, n.name ] -%> <%= CSV.generate_line row %> <%- end -%> I don't have any error, but it simply displays the content of the CSV file, while I'd expect a prompt from the browser to download the file. I've read a lot, but could not find anything that'd work. Do you have an idea? thanks, p.

• How to implement generic callbacks in C++

  - by Kylotan

  Forgive my ignorance in asking this basic question but I've become so used to using Python where this sort of thing is trivial that I've completely forgotten how I would attempt this in C++. I want to be able to pass a callback to a function that performs a slow process in the background, and have it called later when the process is complete. This callback could be a free function, a static function, or a member function. I'd also like to be able to inject some arbitrary arguments in there for context. (ie. Implementing a very poor man's coroutine, in a way.) On top of that, this function will always take a std::string, which is the output of the process. I don't mind if the position of this argument in the final callback parameter list is fixed. I get the feeling that the answer will involve boost::bind and boost::function but I can't work out the precise invocations that would be necessary in order to create arbitrary callables (while currying them to just take a single string), store them in the background process, and invoke the callable correctly with the string parameter.

• Why is the ASP.NET Repeater.Items collection empty, when controls are on the screen?

  - by Ryan

  I have an ASP page with the following repeater: <asp:Repeater runat="server" ID="RegionRepeater" DataSourceID="SqlDataSourceRegions" EnableViewState="true"> <ItemTemplate> <tr> <td valign="top"> <b><%#Eval("description")%></b> <asp:HiddenField runat="server" ID="RegionID" Value='<%#Eval("region_id")%>'/> </td> <td> <asp:FileUpload ID="FileUpload" runat="server" Width="368px" /> </td> </tr> </ItemTemplate> </asp:Repeater> (The repeater is inside a Wizard, inside a content pane). The code behind is connected to the protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) event. There are two items on the screen (two rows inside the table). However, when the code tries to read those items, the Items collection is empty! foreach(RepeaterItem region in RegionRepeater.Items) { // Never runs - the RegionRepeater.Items.Count = 0 FileUpload fileUpload = (FileUpload) region.FindControl("FileUpload"); String regionID = ((HiddenField)region.FindControl("RegionID")).Value; ... Why is the collection empty, when there are controls drawn on the screen? Thanks a lot for any help; this is starting to drive me nuts. (BTW: I tried adding/removing the EnableViewState="true" tag)

• Trying to find a PHP5 API-based embeddable CMS

  - by StrangeElement

  I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

• wordpress extended_valid_elements for script tag?

  - by John

  Can someone tell me how to tell Wordpress' tinymce editor to NOT strip out script tags? I looked in wp-admin/includes/post.php and added 'extended_valid_elements'=>'script[charset|defer|language|src|type]', to the $initArray. When I do a view source on the CMS post editor, I see taht it does show up like so: <script type="text/javascript"> /* <![CDATA[ */ tinyMCEPreInit = { base : "http://dev.esolar.ca/wp-includes/js/tinymce", suffix : "", query : "ver=327-1235", mceInit : {mode:"specific_textareas", editor_selector:"theEditor", width:"100%", theme:"advanced", skin:"wp_theme", theme_advanced_buttons1:"bold,italic,strikethrough,|,bullist,numlist,blockquote,|,justifyleft,justifycenter,justifyright,|,link,unlink,wp_more,|,spellchecker,fullscreen,wp_adv", theme_advanced_buttons2:"formatselect,underline,justifyfull,forecolor,|,pastetext,pasteword,removeformat,|,charmap,|,outdent,indent,|,undo,redo,wp_help", theme_advanced_buttons3:"", theme_advanced_buttons4:"", language:"en", spellchecker_languages:"+English=en,Danish=da,Dutch=nl,Finnish=fi,French=fr,German=de,Italian=it,Polish=pl,Portuguese=pt,Spanish=es,Swedish=sv", theme_advanced_toolbar_location:"top", theme_advanced_toolbar_align:"left", theme_advanced_statusbar_location:"bottom", theme_advanced_resizing:"1", theme_advanced_resize_horizontal:"", dialog_type:"modal", relative_urls:"", remove_script_host:"", convert_urls:"", apply_source_formatting:"", remove_linebreaks:"1", gecko_spellcheck:"1", entities:"38,amp,60,lt,62,gt", accessibility_focus:"1", tabfocus_elements:"major-publishing-actions", media_strict:"", paste_remove_styles:"1", paste_remove_spans:"1", paste_strip_class_attributes:"all", wpeditimage_disable_captions:"", plugins:"safari,inlinepopups,spellchecker,paste,wordpress,media,fullscreen,wpeditimage,wpgallery,tabfocus"}, load_ext : function(url,lang){var sl=tinymce.ScriptLoader;sl.markDone(url+'/langs/'+lang+'.js');sl.markDone(url+'/langs/'+lang+'_dlg.js');} }; /* ]]> */ </script> But for some reason ,my editor still doesn't save <script> tags. What am I doing wrong?

• Discussion on SEO best-practices for site development involving php...

  - by Bradley Herman

  Recently in our work, I've started getting some experience with SEO (finally). It's something I've put off for a long time because I've always maintained that SEO is a buzz-word b.s. pseudo-science and more about providing quality, relevant content (assuming proper header tags and the basics are covered). However, sometimes a client doesn't have stellar content yet still demands SEO and high rankings. While it's not how I design sites 100% of the time (as design dictates structure), I typically create a basic template from the design my boss gives me, then I optimize it, and then strip the top and bottom and move those to header.php and footer.php, using the following to bring in the header and footer based on AJAX versus HTML requests: <?php if($_SERVER['HTTP_X_REQUESTED_WITH']==''){ include('includes/header.php'); }?> #content here <?php if($_SERVER['HTTP_X_REQUESTED_WITH']==''){ include('includes/footer.php'); }?> Then, I use jQuery to intercept page requests and I use AJAX to fill in, for example, a #copy div with the new content. This avoids unnecessarily loading all the header and footer info everytime, but still allows users without Java to access pages without any problems. (also to think about, depending on size of content, do the extra http requests added using this method render it more of a server strain versus a single, larger file?) I don't have a really solid understanding of the meta keywords and their SEO significance, but as I recall reading, the keywords, title, and description on a page should match up to the pages content--ie. each page should have slightly different keywords/description while retaining some common ground. What I'm getting at here is trying to foster a discussion on whether my approach is flawed to begin with, if there are things I can do (within reason) that keep the site structure simple but allow for better SEO practices, or if my SEO understandings are wrong. This isn't a question, per say, but hopefully a constructive discussion here that more than just I can learn from. I appreciate any responses and hope to hear from you. Thanks!
