• What web based programming environments exist, on which to learn?

  - by jjclarkson

  I loved appjet (the programming environment) before it was taken over by Google. What other web based complete programming environments are out there? Which one do you think is best for starting to do real world coding the fastest? I really think coding from your browser will make programming more accessible to the public. Are there any out there that use a vim style, (e.g. jsvi) in combination with free server side hosting? The last time I looked at Bespin it was a little green. Are there others?

• Issue with clipping rectangles and back to front rendering

  - by Milo

  Here is my problem. My rendering algorithm renders from back to front. But logically, clipping rectangles need to be applied from front to back. Hence why the following does not work: void AguiWidgetManager::recursiveRender(const AguiWidget *root) { //recursively calls itself to render widgets from back to front AguiWidget* nonConstRoot = (AguiWidget*)root; if(!nonConstRoot->isVisable()) { return; } //push the clipping rectangle if(nonConstRoot->isClippingChildren()) { graphicsContext->pushClippingRect(nonConstRoot->getClippingRectangle()); } if(nonConstRoot->isEnabled()) { nonConstRoot->paint(AguiPaintEventArgs(true,graphicsContext)); for(std::vector<AguiWidget*>::const_iterator it = root->getPrivateChildBeginIterator(); it != root->getPrivateChildEndIterator(); ++it) { recursiveRender(*it); } for(std::vector<AguiWidget*>::const_iterator it = root->getChildBeginIterator(); it != root->getChildEndIterator(); ++it) { recursiveRender(*it); } } else { nonConstRoot->paint(AguiPaintEventArgs(false,graphicsContext)); for(std::vector<AguiWidget*>::const_iterator it = root->getPrivateChildBeginIterator(); it != root->getPrivateChildEndIterator(); ++it) { recursiveRenderDisabled(*it); } for(std::vector<AguiWidget*>::const_iterator it = root->getChildBeginIterator(); it != root->getChildEndIterator(); ++it) { recursiveRenderDisabled(*it); } } //release clipping rectangle if(nonConstRoot->isClippingChildren()) { graphicsContext->popClippingRect(); } } I could ofcourse go to the top of the tree, then apply clipping rectangles inward until I get to the currently rendered widget, but that would involve lots of clipping rectangles @ 60 frames per second. I want to minimize calls to pushing and popping rectangles. What could I do, Thanks

• (solved) jQuery click and drag/scroll window: jagged movement

  - by Josh

  Edit: derp, using pageX/Y instead of clientX/Y -- apparently scrollBy expects input with that offset rather than the other. Jaggy movement gone. I am getting jagged movement when doing small scroll increments using the following bindings. Can anyone point me in the right direction for how to smooth this out? FYI, its intermittent. It seems like, if I click and hold for a second, then drag at a decent speed there are no problems. Edit: What the hell? I get this output on debug... obvious jog backwards and forwards. This will happen in succession and seems to have no correlation with the mouse, other than the mouse is moving. x 398 : 403 y 374 : 377 x 403 : 399 y 377 : 374 x 399 : 404 y 374 : 377 Josh sococo.client.panMap = function(e){ e.preventDefault(); var movex = sococo.client.currX - e.pageX ; var movey = sococo.client.currY - e.pageY; console.log( sococo.client.currX +" : " + e.pageX ); window.scrollBy(movex,movey); sococo.client.currY = e.pageY; sococo.client.currX = e.pageX; } $(document).mousedown( function(e){ e.preventDefault(); sococo.client.currX = e.pageX; sococo.client.currY = e.pageY; $(document).bind( "mousemove", sococo.client.panMap ); }); $(document).mouseup( function(e){ e.preventDefault(); $(document).unbind( "mousemove", sococo.client.panMap ); });

• Ad Hoc Distribution - Does it update an existing previous installed version of an app?

  - by Kriem

  What happens when a user installs an ad hoc distribution of an existing app? And what happens if this app (or a newer one) hits the App Store officially? To sum it up: A user already has a v1.0 and receives a v2.0 ad hoc A user has the ad hoc v2.0 and the official public release of v2.0 hits the store A user has the ad hoc v2.0 and an official public release of v3.0 hits the store In other words, is the ad hoc version a stand-alone build or does it in fact update a previous version as expected from an update? And will it be updated as soon as a newer version hits the store?

• Making a lightbox support printing on web page

  - by bobo

  I know the idea is to use a separate stylesheet for printing that hides everything other than the lightbox when the user clicks the print button on the lightbox. It sounds easy but there are always some obstacles. So I would like to know if there is any working example that supports all major browsers. I searched in google and found many lightbox but none of them has a print button built-in.

• Table is centering by itself?

  - by user146780

  I have a page here: http://animactions.ca/Animactions/accueil.php and it has a right column. When the right column's content is longer than then the main content, the main content centers rather than start at the top despite I defining it in a style not to do so. From my style sheet: .tbsyles { margin: 0px; text-align: justify; width: 200px; border-left-style: solid; border-left-width: 1px; border-left-color: #A8CFE4; padding-left: 30px; height: 100%; line-height: 100%; vertical-align: top; padding-right: 0px; } .tablestylea { width: 900px; margin: 0px; text-align: justify; height: 100%; line-height: 100%; vertical-align: top; padding-right: 0px; } How can I make it so no matter what the length of my right col content the main content page resizes correctly and starts from the top rather than from the center? Thanks

• Could an ontology suitably replace an RDBMS for a web app?

  - by Thomas

  I'm considering storing the content of a web app in an RDF or OWL ontology instead of an RDBMS. However, when I research ontologies they seem to always exist in the context of publicly accessible data stores serving as the backbone of the semantic web. I've never heard of them being used as the content engine behind a web app. Is it reasonable to use an ontology instead of an RDBMS for such an application? (Again, this is just for content. User data, commerce and stuff like that will stay in a database as I see no need to reinvent the wheel there.)

• Fastest Method to Learn Web Design for a Developer

  - by hekevintran

  I am a Web developer and in my projects I have noticed that my weakest point is not being good at the front-end design. Relying on other designers can be annoying if they are not able to produce as quickly as I want. My perspective on HTML/CSS is that it is basically a big hack that amazingly works. There are too many CSS and browser specific bugs/quirks to learn and remember them all without spending extreme amounts of time trying to untangle everything. Is there a fast track route to getting CSS into my brain? I have looked at some CSS books, but to me they really read as long lists of how to render things correctly in IE6 and how to make corners rounded. (Seriously why does it require so many tricks to make a sharp corner round? On any platform but the Web this would be called a major oversight.) Does there exist something that does the analogous to CSS that jQuery does for JavaScript? Using jQuery you don't need to know JavaScript well to make things that work. I am not interested in learning why IE6 does things in weird ways because I don't care about supporting it at all. I am more interested in a method of learning how to use CSS to do what I want without spending hours and hours reading obscure blogs.

• Non-Mainstream Languages, Bad for your resume?

  - by Joe

  Hi folks, I got my BS in Computer Science about seven years ago. I spent two years in neuroscience research and the next three providing what amounts to tech support. But I love computer programming - and I have since written, as a freelancer, non-trivial commercial code in Haskell, Smalltalk, and Objective-C. I used these languages because I find them rewarding, they make me a better programmer and thus, I thought, more attractive to companies. However the polar opposite has occured and I am now unhireable. The freelance market has bottomed out and I am looking for regular employment. But I am being repeatedly turned down, even for entry-level positions, because I don't specifically fit the requirements - eg. Java programmer with 2+ years with JUnit, JavaMail, Servlets etc. And none of the hiring managers, let alone the recruiters, have heard of either Haskell or Smalltalk and more disturbing is their thinly veiled contempt for my background. My question is , how should I market myself to these positions? Is anyone here in a similar position? What should I be doing different professionally? More broadly is this contempt for non-mainstream experience occurring everywhere or just my town? And if there are any hiring managers reading this, I'd love to hear your side. Please be brutally honest. thanks, joe

• Graphics library used by Windows Vista Freecell and Solitaire

  - by David Grayson

  Does anyone know what graphics library is used to create the graphics in the Solitaire and Freecell games included with Windows Vista (e.g. XNA, GDI, WPF)? A good answer would include the name of the library and evidence. I looked at solitaire.exe with dependency walker and it shows many calls to gdi32.dll and gdiplus.dll, but also a call to Direct3DCreate9 in d3d9.dll.

• Combining deflate and minify - am i creating overhead?

  - by Mark Nolan

  I minify my css and js files on the fly with google.codes minify. I have also set my .htaccess to use deflate on all my css and js files - the reason beeing some js files (like shadowbox and tinymce) reference to other js files in the code. So i'm compressing with apache deflate and also minify compresses some js and css files with gzip - am i creating overhead by doing this - first gzipping (minify) and then zlib (deflate) will run through again. Or will apache deflate ignore the already gzipped files having the attributes set by minify in the headers. Anyone have any experiences with this?

• Google OpenID changes?!?!?

  - by Andrea

  I'm trying to implement OpenId login for a web application. Whenever new user who logs in via OpenId I create a new user on the sustem, and among the data I store their openid URL, so that next time they login with that user. I'm testing this with my Gmail OpenID, and the problem is that everytime I do this, Google sends a different openid URL, that is, https://www.google.com/accounts/o8/id?id=SomethingThatChangesFromTimeToTime Of course I'm then not able to tell wheter this is or not a new user. I'm a bit puzzled: shouldn't the openid identifier always remain the same?

• Overriding SQLMembershipProvider

  - by vikp

  Is there built in methods into .net framework to do the following: Get role GUID from user name/user GUID Get role name from role GUID So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this? I have the following methods that I store in the ASPUtilities class: getRoleGUID(guid userGuid) { LINQ joins } getRoleGuid(string userName) { LINQ joins } getRoleName(guid roleGuid) { LINQ joins } EDIT: I have just looked into extending SQLMembershipProvider examples. Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?

• How do I create Twitter style URL's for my app - Using existing application or app redesign - Ruby o

  - by bgadoci

  I have developed a blog application of sorts that I am trying to allow other users to take advantage of (for free and mostly for family). I wondering if the authentication I have set up will allow for such a thing. Here is the scenario. Currently the application allows for users to sign up for an account and when they do so they can create blog posts and organize those posts via tags. The application displays no data publicly (another words, you have to login to see anything). To gain access you have to create an account and even after you do, you cannot see anyone else's information as the applications filters using the current_user method and displays in the /posts/index.html.erb page. This would be great if a user only wanted to blog and share it with themselves, not really what I am looking for. My question has two parts (hopefully I won't make anyone mad by not putting these into two questions) Is it possible for a particular users data to live at www.myapplication.com/user without moving everything to the /user/show.html.erb file? Is it possible to make some of that information (living at the URL) public but still require login for create and destroy actions. Essentially, exactly like twitter. I am just curious if I can get from where I am (using the current_user methods across controllers to display in /posts/index.html.erb) to where I want to be. My fear is that I have to redesign the app such that the user data lives in the /user/show.html.erb page. Thoughts?

I wonder if there is something I can set in the vendored gem path to represent the /posts/index.html.erb code as the /user/id code and replace id with the user name.

• TinyMCE is modifying the XHTML 1.0 Strict HTML I input. How can I stop it?

  - by Matt

  The code I want to have saved through TinyMCE is as follows: <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="550" height="90" id="homepage-banner"> <param name="movie" value="/images/header.swf" /> <param name="wmode" value="transparent" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="/images/header.swf" width="550" height="90"> <param name="wmode" value="transparent" /> <!--<![endif]--> <img src="/images/header.jpg" width="550" height="90" alt="" border="0" /> <!--[if !IE]>--> </object> <!--<![endif]--> </object> Sadly, what I end up with is: <object data="/images/header.swf" height="90" type="application/x-shockwave-flash" width="550"> <param name="id" value="homepage-banner" /> <param name="wmode" value="transparent" /> <param name="src" value="/images/header.swf" /> </object> The purpose of the stripped parts of the code is to provide a fallback image if flash is not available on the client. In my tinyMCE.init({ ... }); I am using verify_html: true and valid_elements is set as per this forum topic whereby all valid XHTML 1.0 Strict elements are allowed. I have checked and the above code does comply with the XHTML 1.0 Strict standard. I have tried just setting verify_html to false but it had no effect. How can TinyMCE be configured to leave my HTML alone?!
