• Setting the target and parent dropdown values from a DB when using CascadingDropDown

  - by Ryan

  Hi, I have two dropdown lists with Cascading Dropdown, in the usual fashion: <asp:DropDownList ID="DropDownListIndustry" runat="server" DataSourceID="SqlDataSourceIndustries" DataTextField="name" DataValueField="industry_id" AppendDataBoundItems=" <asp:ListItem Text="(Please Select)" Value="-1" /> </asp:DropDownList> &nbsp;&nbsp; <ajax:CascadingDropDown ID="CascadingDropDownIndustry" runat="server" ParentControlID="DropDownListIndustry" TargetControlID="DropDownListSubIndustry" ServicePath="AjaxDataProvider.asmx" ServiceMethod="GetSubIndustry" Category="SubIndustry" /> <asp:DropDownList ID="DropDownListSubIndustry" runat="server"/> No surprises there. However, I sometimes want to set the values of the parent and target from a DB (I want to default them, based on a code entered by the user; the whole thing is wrapped in an update panel). So if the user keys in ABC, I look up ABC in the DB and default the Parent DropDown to ID 10 and Child DropDown to ID 101. However, this fails because the child has no items when the server side code runs (the web script method hasn't run, because the content of the parent dd wasn't changed on the client side) Does anybody know how to work around this? Thanks for any help! Ryan

• Is there a programming toolkit for converting "any file type" to a TIFF image?

  - by Ryan

  Hello, I've written several variations of a program. The purpose of the program is to convert "any file type" to a TIFF image represenation of that file, as if it were being printed using a printer. I'm currently using a third party printer driver that I send files to, and it outputs a TIFF image. This is nice, but it requires me to use Office Interop files, and interact with each individual processing application in order to print the files. I had previously tried a toolkit, called Apose .NET, which did not rely on Office Interop, and did not require any printer driver. It did the conversion all on its own and would create a TIFF image. The problem with Aspose .NET was that it did not support a wide variety of input file types. Most notably, it can't do Visio files. My project calls for the ability to create a TIFF image for virtually "any file type". (excluding exes, music files, and stuff) I know that finding something that handles literally any file type is probably not a very feasible task, so I figure if it can at least handle all the Office file types, Adobe types, and other major standard file types, then I can write a custom extension parsing module that uses those processing applications to do the printing of any file type that can be viewed using those applications. So, does anyone know of a toolkit that can do this? Preferably one that does not rely on Office or a printer driver. It does not have to be free, or open source. Or, if you know of an amazing printer driver that does this, I'm open to that too. Thanks in advance, Ryan

• a:hover background-postition problem

  - by Ryan

  For some reason, I am not entirely sure why, but the following is not working. The background position simply stays the same on hover. I cannot figure out why. I could do it another way, but I would like to try and get to the bottom of why it does not work. #nav a:link, #nav a:visited { background:url(../img/nav-sprite.png) no-repeat; display:block; float:left; height:200px; padding:10px; text-indent:-9999px; border:solid 1px red; } #nav a#home { background-position:-10px 0px; width:30px; } #nav a#about-us { background-position:-85px 0px; width:45px; } #nav a:hover { background-position:1px -15px; } Does anybody know what could be causing this? Thanks in advance! Ryan

• PHP mail() function not delivering mail

  - by Ryan Jones

  Hi there, I have a slight problem. I am using a working script (works on my testing account - shared server) to send a mail through PHP using the mail() function. I just got a dedicated server, and I haven't been able to get the function to work. I've spent the last 10 or so hours reading various documentations on BIND (for the SPF record), dovecot, sendmail and postfix trying various things to get this to work. There is clearly something that I am missing. So we know the PHP code works fine. All the headers are fine everything. We know this as it's a direct copy from my testing account. So the problem must arise somewhere in the server config. The path to sendmail is correct, and sendmail is (apparently) working fine. I've set up the script to now deliver "Sent" or "Error" based on the boolean result from the PHP mail() function. That is: if(mail($blah,$blah,$blah,$blah,$blah)) { echo "Sent"; } else { echo "Error";} And the result ALWAYS comes up as "Sent" - however, the email never arrives. Can someone suggest things to check, as I'm completely new to this (24 hours or so!). Thanks in advance. Ryan

• How to draw an overlay on a SurfaceView used by Camera on Android?

  - by Cristian Castiblanco

  I have a simple program that draws the preview of the Camera into a SurfaceView. What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView, in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class Superficie extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder mHolder; public Camera camera; Superficie(Context context) { super(context); mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(final SurfaceHolder holder) { camera = Camera.open(); try { camera.setPreviewDisplay(holder); camera.setPreviewCallback(new PreviewCallback() { public void onPreviewFrame(byte[] data, Camera arg1) { invalidar(); } }); } catch (IOException e) {} } public void invalidar(){ invalidate(); } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { Camera.Parameters parameters = camera.getParameters(); parameters.setPreviewSize(w, h); camera.setParameters(parameters); camera.startPreview(); } @Override public void draw(Canvas canvas) { super.draw(canvas); // nothing gets drawn :( Paint p = new Paint(Color.RED); canvas.drawText("PREVIEW", canvas.getWidth() / 2, canvas.getHeight() / 2, p); } }

• Linux Lightweight Distro and X Windows for Development

  - by Fernando Barrocal

  Heyall... I want to build a lightweight linux configuration to use for development. The first idea is to use it inside a Virtual Machine under Windows, or old Laptops with 1Gb RAM top. Maybe even a distributable environment for developers. So the whole idea is to use a LAMP server, Java Application Server (Tomcat or Jetty) and X Windows (any Window manager, from FVWM to Enlightment), Eclipse, maybe jEdit and of course Firefox. Edit: I am changing this post to compile a possible list of distros and window managers that can be used to configure a real lightweight development environment. I am using as base personal experiences on this matter. Info about the distros can be easily found in their sites. So please, focus on personal use of those systems Distros Ubuntu / Xubuntu Pros: Personal Experience in old systems or low RAM environment - @Schroeder, @SCdF Several sugestions based on personal knowledge - @Kyle, @Peter Hoffmann Gentoo Pros: Not targeted to Desktop Users - @paan Don't come with a huge ammount of applications - @paan Slackware Pros: Suggested as best performance in a wise install/configuration - @Ryan Damn Small Linux Pros: Main focus is the lightweight factor - 50MB LiveCD - @Ryan Debian Pros: Very versatile, can be configured for both heavy and lightweight computers - @Ryan APT as package manager - @Kyle Based on compatibility and usability - @Kyle -- Fell Free to add Prós and Cons on this, so we can compile a good Reference. -- X Windows suggestion keep coming about XFCE. If others are to add here, open a session for it Like the distro one :)

• Jquery Cycle Lite plugin unable to see images that have been loaded by an AJAX call

  - by William Macdonald

  Hi, I am having problems using the jquery cycle lite plugin on some images that are added via AJAX. Here is the jquery code: $(function() { resizeWindow(); $(window).bind("resize", resizeWindow); $("#assignment-nav").accordion({ header: "h3", autoHeight: false }); $(".project").click(function() { // get the HTML and load into div $('.image-holder').empty(); var justTheNumber = $(this).attr('id').replace('project-',''); $.get("get_project_images.php", {project_id:justTheNumber}, function(data){ $('.image-holder').append(data); } ); $(".image-holder").cycle({ // Cycle plugin prev: '#prev', next: '#next', timeout: 0, speed: 250 }) }); }); My code works fine in that the IMG tags are loaded and the first image of the slide show is displayed. However the prev/next buttons don't work. When I load the images via static HTML the slideshow prev/next links works fine. (I just copied and pasted the generated HTML.) I understand I need to use something like .bind or .live to make the Cycle plugin 'see' the new images. I have tried everything I can think of but I can't make it work. What am I doing wrong ?

• Java Concurrency in practice sample question

  - by andy boot

  I am reading "Java Concurrency in practice" and looking at the example code on page 51. According to the book this piece of code is at risk of of failure if it has not been published properly. Because I like to code examples and break them to prove how they work. I have tried to make it throw an AssertionError but have failed. (Leading me to my previous question) Can anyone post sample code so that an AssertionError is thrown? Rule: Do not modify the Holder class. public class Holder{ private int n; public Holder(int n){ this.n = n; } public void assertSanity(){ if (n != n) { throw new AssertionError("This statement is false"); } } } I have modified the class to make it more fragile but I still can not get an AssertionError thrown. class Holder2{ private int n; private int n2; public Holder2(int n) throws InterruptedException{ this.n = n; Thread.sleep(200); this.n2 = n; } public void assertSanity(){ if (n != n2) { throw new AssertionError("This statement is false"); } } } Is it possible to make either of the above classes throw an AssertionError? Or do we have to accept that they may occasionally do so and we can't write code to prove it?

• Best way to make a WYSIWYG in Flex?

  - by hngry4powr

  Hello, I have a client that wants a WYSIWYG form that behaves like MS word. It will have some section labels in it, with users expected to enter notes for each section, and it needs a place holder for a chart. The trick is that the user needs to know where page breaks are going to fall when printed. The customer agrees to fixed size paper with fixed sized margins. How should I approach this challenge? Thank you very much for your suggestions. Here is an example: Section 1: Explain Idea Here { As user types in this section, the space between this section and the next section expands, but I as the user can't delete the lines that say Section 1 or 2, or the place holder for the chart. However if I type a lot of text, I need to display where the page breaks are with a dashed line or something, so the user can make sure the content enters appears on the desired page. If I type a lot here for example, section 2 will get pushed onto the next page} Section 2: State why this is a Good Idea [ PLACE HOLDER FOR CHART . . . ] Section 3: Additional Remarks:

• Jquery selectors question

  - by Ben

  Hi all, I am not an expert at jquery but trying to get a menu to work. Basically, I have a menu made of up to 3 levels of nested lists. The first level has a little arrow has a background image that opens or close when opening the first level list. Any other nested lists don't need to have the background image. My script opens the menu when you click on it and is also supposed to switch the first level list from a class "inactive" to a class "active". Here is the script: $(document).ready(function(){ $("#left-navigation-holder ul.level1 li.inactive").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $("#left-navigation-holder li a").click(function(){ menu = $(this).parent('li').children('ul'); menu.toggle(); }); }); The problem is that the toggle function also happens when clicking on second and third level lists causing the arrows to toggle even if the first level list isn't clicked on. I thought using $("#left-navigation-holder ul.level1 li.inactive").toggle would limit the function to the first level list with a class "inactive". Any help would be really appreciated. Ben

• Recursive powerof-function, see if you can solve it

  - by Jonas B

  First of all, this is not schoolwork - just my curiousity as I for some reason can't get my head around it and solve it. I come up with these stupid things all the time and it annoys the hell out of me when I cant solve them. Code example is in C# but solution doesn't have to be in any particular programming-language. long powerofnum(short num, long powerof) { return powerofnum2(num, powerof, powerof); } long powerofnum2(short num, long powerof, long holder) { if (num == 1) return powerof; else { return powerof = powerofnum2(num - 1, holder * powerof, holder); } } As you can see I have two methods. I call for powerofnum(value, powerofvalue) which then calls the next method with the powerofvalue also in a third parameter as a placeholder so it remembers the original powerof value through the recursion. What I want to accomplish is to do this with only one method. I know I could just declare a variable in the first method with the powerof value to remember it and then iterate from 0 to value of num. But as this is a theoretical question I want it done recursively. I could also in the first method just take a third parameter called whatever to store the value just like I do in the second method that is called by the first, but that looks really stupid. Why should you have to write what seems like the same parameter twice? Rules explained in short: no iteration scope-specific variables only only one method Anyhow, I'd appreciate a clean solution. Good luck :)

• vaadin custom layout setting a text area in a table with the location attribute

  - by user3717298

  I need to set a text area in the html template and use it as a custom component in vaadin the html snippet is as below <table> <tr> <td> JUNK SENTENCE </td> <td> <div location="HEADIN"></div> <div location="Details"></div> <div location="Attachment"></div> </td> <td> <p>School of more than 50 students univer versities.</p> </td> </tr> </table> All the place holders are working and displays data but the "details" holder should be a text area. as the text is a lot over there so I tried the below way but it just turned the place holder to text vaadin could not manipulate / identify the "Details" place holder. I tried the below way i set - in side the text area tag. <textarea rows="4" cols="50"> </textarea> and again i tried this way too which also did not work. <textarea rows="4" cols="50" location="Details"> </textarea> Any guidance would be appreciated to solve this I am setting the needed values from a formfeildfactory and these values are set by implementing the Vaadin Custom field class(in case it helps some more to identify)

• Eclipse Check for Updates issue

  - by Nicholas Ryan Bowers

  I install Eclipse from the Software Center so it links up and will be updated with the rest of my software. Because I am developing for Android, however, I have to install the ADT Plugin within Eclipse by going to Help Install new software (or something to that effect). Now, I do understand that I can update Eclipse through the actual Ubuntu software center/system, but in order to update plugins and extensions within Eclipse, I have to go to Help Check for Updates (which then scans all plugins for updates). The only issue, is that when I installed through the software center, the owner became root, and whenever I run it without root, I'm not able to update - I get the error message "Insufficient access privileges to apply this update." When I run it as root, all of my plugins disappear, because I guess I installed them as myself, not as root. I tried to install the plugins as root, but the Install New Software choice would not work. Ubuntu 12.04 and Eclipse 3.7.2-1

• Modifying AD Schema permissions from the command line

  - by Ryan Roussel

  Recently while making some changes for a client, I accidently dug myself into a pretty deep hole.  I was trying to explicitly deny a certain user from reading a few group policies including the Default Domain Policy.  When I went in to make the change I accidently denied Authenticated Users rather than the AD user object.  This of course made the GPO inaccessible to all users including any with domain admin rights.  The policy could no longer be modified in the GPMC and worse, changes could not be made through ADSIedit.   The errors I was getting from inside ADSIedit when trying to edit the container looked like this This object has one or more property sheets currently open. Invalid path to object The only solution was to strip Authenticated Users from the container ACL completely in the schema, then re-add it back with the default read and apply rights.  To perform this action, I used a command I had never used before:  DSALCS.exe  It’s part of the DSMOD group of tools.  Since this command interacts with the actual schema, you have to know the full LDAP container or object name.  In this case the GUID of the Default Domain Policy: {31B2F340-016D-11D2-945F-00C04FB984F9}   The actual commands I ran looked like this:   To display the current ACL of the container: c:\>dsacls “cn={31B2F340-016D-11D2-945F-00C04FB984F9},cn=Policies,cn=System, dc=domain,dc=com” /A To strip Authenticated Users from the ACL of the container: c:\>dsacls “cn={31B2F340-016D-11D2-945F-00C04FB984F9},cn=Policies,cn=System, dc=domain,dc=com” /R “NT Authority\Authenticated Users”   For full reference of the DSACLS.EXE command visit: http://support.microsoft.com/kb/281146 Once the Authenticated Users was cleared from the ACL, I was able to use Group Policy Management Console to reassign the default permissions.

• Visio 2010 forward engineer add-in for office 2010

  - by Ryan Ternier

  I have been scouring the internet for ages trying to see if there was a usable add-on for Visio 2010 that could export SQL Scripts. MS stopping putting that functionality in Visio since 2003 – which is a huge shame. Today I found an open source project from Alberto Ferrari. It’s an add-in for Visio 2010 that allows you to generate SQL Scripts from your DB diagram. It’s still in beta, and the source is available.   Check it out here:http://sqlblog.com/blogs/alberto_ferrari/archive/2010/04/16/visio-forward-engineer-addin-for-office-2010.aspx This saves me from having to do all my diagramming in SQL Server / VS 2010. And brings back the much needed functionality that has been lost.

• Installer Reboots at "Detecting hardware" (disks and other hardware) on all recent Server Installs

  - by Ryan Rosario

  I have a very frustrating problem with my PC. I cannot install any recent version of Ubuntu Server (or even Desktop) since 9.04 even using the text-based installer. I boot from a USB stick created by Unetbootin (I also tried other methods such as startup disk creator with no difference). On the Server installer, it gets to "Detecting Hardware" (the second one about disks and all other hardware, not network hardware) and then either hangs at 0% (waited 24 hours), or reboots after a minute or two. My system (late 2007): ASUS P5NSLI motherboard Intel Core 2 Duo E6600 2.4Ghz 2 x 1GB Corsair 667MHz RAM nVidia GeForce 6600 I have unplugged everything (including the only hard disk, CD-ROMs and floppy). I have only one stick of RAM (tried each one to no avail) and am booting the installer from a USB stick (booting from CD-ROM yields the same problem). I also tried several of the boot options (nomodeset, nousb, acpi=off, noapic, i915.modeset=1/0, xforcevesa) in all combinations) to no avail. The only active parts of my system are the video card, mouse, keyboard and USB stick. I have also updated the BIOS to the most recent version. (FWIW, on the Desktop installer, I get a black screen after hitting the Install option.) Even after removing "quiet" I am unable to see what kernel panic is occurring (or not occurring) to cause the install to crash. I am only able to save the debug logs via a simple webserver in the installer. After the last line (I repeatedly refreshed), the server stops responding and the installer hangs or reboots: Jan 2 01:04:03 main-menu[302]: INFO: Menu item 'disk-detect' selected Jan 2 01:04:04 kernel: [ 309.154372] sata_nv 0000:00:0e.0: version 3.5 Jan 2 01:04:04 kernel: [ 309.154409] sata_nv 0000:00:0e.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.154531] sata_nv 0000:00:0e.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.164442] scsi0 : sata_nv Jan 2 01:04:04 kernel: [ 309.167610] scsi1 : sata_nv Jan 2 01:04:04 kernel: [ 309.167762] ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xd400 irq 10 Jan 2 01:04:04 kernel: [ 309.167774] ata2: SATA max UDMA/133 cmd 0x970 ctl 0xb70 bmdma 0xd408 irq 10 Jan 2 01:04:04 kernel: [ 309.167948] sata_nv 0000:00:0f.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.168071] sata_nv 0000:00:0f.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.171931] scsi2 : sata_nv Jan 2 01:04:04 kernel: [ 309.173793] scsi3 : sata_nv Jan 2 01:04:04 kernel: [ 309.173943] ata3: SATA max UDMA/133 cmd 0x9e0 ctl 0xbe0 bmdma 0xe800 irq 11 Jan 2 01:04:04 kernel: [ 309.173954] ata4: SATA max UDMA/133 cmd 0x960 ctl 0xb60 bmdma 0xe808 irq 11 Jan 2 01:04:04 kernel: [ 309.174061] pata_amd 0000:00:0d.0: version 0.4.1 Jan 2 01:04:04 kernel: [ 309.174160] pata_amd 0000:00:0d.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.177045] scsi4 : pata_amd Jan 2 01:04:04 kernel: [ 309.178628] scsi5 : pata_amd Jan 2 01:04:04 kernel: [ 309.178801] ata5: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xf000 irq 14 Jan 2 01:04:04 kernel: [ 309.178811] ata6: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xf008 irq 15 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface eth0 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface lo Jan 2 01:04:04 kernel: [ 309.485062] ata3: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:04 kernel: [ 309.633094] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Jan 2 01:04:04 kernel: [ 309.641647] ata1.00: ATA-8: ST31000528AS, CC38, max UDMA/133 Jan 2 01:04:04 kernel: [ 309.641658] ata1.00: 1953525168 sectors, multi 1: LBA48 NCQ (depth 31/32) Jan 2 01:04:04 kernel: [ 309.657614] ata1.00: configured for UDMA/133 Jan 2 01:04:04 kernel: [ 309.657969] scsi 0:0:0:0: Direct-Access ATA ST31000528AS CC38 PQ: 0 ANSI: 5 Jan 2 01:04:04 kernel: [ 309.658482] sd 0:0:0:0: Attached scsi generic sg0 type 0 Jan 2 01:04:04 kernel: [ 309.658588] sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) Jan 2 01:04:04 kernel: [ 309.658812] sd 0:0:0:0: [sda] Write Protect is off Jan 2 01:04:04 kernel: [ 309.658823] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Jan 2 01:04:04 kernel: [ 309.658918] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 2 01:04:04 kernel: [ 309.675630] sda: sda1 sda2 Jan 2 01:04:04 kernel: [ 309.676440] sd 0:0:0:0: [sda] Attached SCSI disk Jan 2 01:04:05 kernel: [ 309.969102] ata2: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:05 kernel: [ 310.281137] ata4: SATA link down (SStatus 0 SControl 300) Anybody have any additional ideas I could try?

• Java Script – Content delivery networks (CDN) can bit you in the butt.

  - by Ryan Ternier

  As much as I love the new CDN’s that Google, Microsoft and a few others have publically released, there are some strong gotchas that could come up and bite you in the ass if you’re not careful. But before we jump into that, for those that are not 100% sure what a CDN is (besides Canadian).   Content Delivery Network. A way of distributing your static content across various servers in different physical locations.  Because this static content is stored on many servers around the world, whenever a user needs to access this content, they are given the closest server to their location for this data. Already you can probably see the immediate bonuses to a system like this: Lower bandwidth Even small script files downloaded thousands of times will start to take a noticeable hit on your bandwidth meter. Less connections/hits to your web server which gives better latency If you manage many servers, you don’t need to manually update each server with scripts. A user will download a script for each website they visit. If a user is redirected to many domains/sub-domains within your web site, they might download many copies of the same file. When a system sees multiple requests from the same  domain, they will ignore the download   Those are just a handful of the many bonuses a CDN will give you. And for the average website, a CDN is great choice. Check out the following CDN links for their solutions: Google AJAX Library: http://code.google.com/apis/ajaxlibs/ Microsoft Ajax library: http://www.asp.net/ajaxlibrary/cdn.ashx The Gotcha There is always a catch. Here are some issues I found with using CDN’s that hopefully can help you make your decision. HTTP / HTTPS If you are running a website behind SSL, make sure that when you reference your CDN data that you use https:// vs. http://. If you forget this users will get a very nice message telling them that their secure connection is trying to access unsecure data. For a developer this is fairly simple, but general users will get a bit anxious when seeing this. Trusted Sites Internet Explorer has this really nifty feature that allows users to specify what sites they trust, and by some defaults IE7 only allows trusted sites to be viewed.  No problem, they set your website as trusted. But what about your CDN? If a user sets your websites to trusted, but not the CDN, they will not download those static files. This has the potential to totally break your web site. Pedantic Network Admins This alone is sometimes the killer of projects. However, always be careful when you are going to use a CDN for a professional project. If a network / security admin sees that you’re referencing an outside source, or that a call from a website might hit an outside domain.. panties will be bunched, emails will be spewed out and well, no one wants that.

• Ways to use your skills as a developer to give back to the community/charities.

  - by Ryan Hayes

  Recently I came upon a community event called GiveCamp. GiveCamp is a weekend-long event where technology professionals from designers, developers and database administrators to marketers and web strategists donate their time to provide solutions for non-profit organizations. Since its inception in 2007, the GiveCamp program has provided benefits to over 150 charities, with a value of developer and designer time exceeding $1,000,000 in services! Coming from a very rural part of the country where there is a huge opportunity for charity events like this, it got me wondering. Are there other large movements like GiveCamp that are out there? GiveCamp is sponsored by Microsoft, so of course most are run through .NET user groups. Are there other flavors of it? Different types? Java/Python/other open source charity movements? If not, how do you give back?

• WebGL First Person Camera - Matrix issues

  - by Ryan Welsh

  I have been trying to make a WebGL FPS camera.I have all the inputs working correctly (I think) but when it comes to applying the position and rotation data to the view matrix I am a little lost. The results can be viewed here http://thistlestaffing.net/masters/camera/index.html and the code here var camera = { yaw: 0.0, pitch: 0.0, moveVelocity: 1.0, position: [0.0, 0.0, -70.0] }; var viewMatrix = mat4.create(); var rotSpeed = 0.1; camera.init = function(canvas){ var ratio = canvas.clientWidth / canvas.clientHeight; var left = -1; var right = 1; var bottom = -1.0; var top = 1.0; var near = 1.0; var far = 1000.0; mat4.frustum(projectionMatrix, left, right, bottom, top, near, far); viewMatrix = mat4.create(); mat4.rotateY(viewMatrix, viewMatrix, camera.yaw); mat4.rotateX(viewMatrix, viewMatrix, camera.pitch); mat4.translate(viewMatrix, viewMatrix, camera.position); } camera.update = function(){ viewMatrix = mat4.create(); mat4.rotateY(viewMatrix, viewMatrix, camera.yaw); mat4.rotateX(viewMatrix, viewMatrix, camera.pitch); mat4.translate(viewMatrix, viewMatrix, camera.position); } //prevent camera pitch from going above 90 and reset yaw when it goes over 360 camera.lockCamera = function(){ if(camera.pitch > 90.0){ camera.pitch = 90; } if(camera.pitch < -90){ camera.pitch = -90; } if(camera.yaw <0.0){ camera.yaw = camera.yaw + 360; } if(camera.yaw >360.0){ camera.yaw = camera.yaw - 0.0; } } camera.translateCamera = function(distance, direction){ //calculate where we are looking at in radians and add the direction we want to go in ie WASD keys var radian = glMatrix.toRadian(camera.yaw + direction); //console.log(camera.position[3], radian, distance, direction); //calc X coord camera.position[0] = camera.position[0] - Math.sin(radian) * distance; //calc Z coord camera.position[2] = camera.position [2] - Math.cos(radian) * distance; console.log(camera.position [2] - (Math.cos(radian) * distance)); } camera.rotateUp = function(distance, direction){ var radian = glMatrix.toRadian(camera.pitch + direction); //calc Y coord camera.position[1] = camera.position[1] + Math.sin(radian) * distance; } camera.moveForward = function(){ if(camera.pitch!=90 && camera.pitch!=-90){ camera.translateCamera(-camera.moveVelocity, 0.0); } camera.rotateUp(camera.moveVelocity, 0.0); } camera.moveBack = function(){ if(camera.pitch!=90 && camera.pitch!=-90){ camera.translateCamera(-camera.moveVelocity, 180.0); } camera.rotateUp(camera.moveVelocity, 180.0); } camera.moveLeft = function(){ camera.translateCamera(-camera.moveVelocity, 270.0); } camera.moveRight = function(){ camera.translateCamera(-camera.moveVelocity, 90.0); } camera.lookUp = function(){ camera.pitch = camera.pitch + rotSpeed; camera.lockCamera(); } camera.lookDown = function(){ camera.pitch = camera.pitch - rotSpeed; camera.lockCamera(); } camera.lookLeft = function(){ camera.yaw= camera.yaw - rotSpeed; camera.lockCamera(); } camera.lookRight = function(){ camera.yaw = camera.yaw + rotSpeed; camera.lockCamera(); } . If there is no problem with my camera then I am doing some matrix calculations within my draw function where a problem might be. //position cube 1 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.translate(worldMatrix, worldMatrix, [-20.0, 0.0, -30.0]); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); setShaderMatrix(); gl.bindBuffer(gl.ARRAY_BUFFER, vertexBuffer); gl.vertexAttribPointer(shaderProgram.attPosition, 3, gl.FLOAT, false, 8*4,0); gl.vertexAttribPointer(shaderProgram.attTexCoord, 2, gl.FLOAT, false, 8*4, 3*4); gl.vertexAttribPointer(shaderProgram.attNormal, 3, gl.FLOAT, false, 8*4, 5*4); gl.activeTexture(gl.TEXTURE0); gl.bindTexture(gl.TEXTURE_2D, myTexture); gl.uniform1i(shaderProgram.uniSampler, 0); gl.useProgram(shaderProgram); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); //position cube 2 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); mat4.translate(worldMatrix, worldMatrix, [40.0, 0.0, -30.0]); setShaderMatrix(); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); //position cube 3 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); mat4.translate(worldMatrix, worldMatrix, [20.0, 0.0, -100.0]); setShaderMatrix(); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); camera.update();

• Is it smart to give idea to company?

  - by Ryan

  I have a few interesting ideas (business ideas) that can be implemented as add-on features of existing business products (web-based products, mostly startups). Based on experience, can anyone let me know if telling them would be a good idea or not? I'm hoping to get some feedback from both sides (company insiders and outsiders). The upside: They could like it and think about bringing me on board to help build. The downside: They take the idea and implement it. Company size for one is less than 50. Another is less than 25.

• Grub 'Read Error' - Only Loads with LiveCD

  - by Ryan Sharp

  Problem After installing Ubuntu to complete my Windows 7/Ubuntu 12.04 dual-boot setup, Grub just wouldn't load at all unless I boot from the LiveCD. Afterwards, everything works completely normal.

My only hopes are that I can solve this, and that doing so won't require re-installation of Grub due to how complicated the procedures are, or that I would be needed to reinstall the OS', as I have done so about six times already since friday due to several other issues I've encountered. Thank you, and good day. System Ubuntu 12.04 64-bit / Windows 7 SP1 64-bit 64GB SSD as boot/OS drive, 1TB HDD as /Home Swap and Steam drive.

• Forwarding a subdomain to main domain using Godaddy.

  - by Ryan Hayes

  I have current blog, which was hosted on Tumblr at http://blog.ryanhayes.net. I'm moving it over to http://ryanhayes.net, and have all the 301 redirects set up for the blog entries to map to my new blog, which is hosted using Godaddy (domain included). When I try to set up a subdomain forward, I'm greeted with a nice 403 Forbidden response (as of this writing, you can see it at http://blog.ryanhayes.net. When I try to ping both the subdomain and domain, they point to the same IP address, so I know blog subdomain has at least switched over to point to the same content. I don't really understand why I would get a 403 Forbidden on the same content that I can see perfectly fine via another domain. Currently, I have a CNAME of blog pointing to @, which is how "www" is set up to forward, so I'm assuming it would do the same thing. My question is what is the proper way to set up my DNS to make the blog subdomain forward to my main domain (301) using the GoDaddy DNS manager? Bonus: What is the background on why I am getting a 403 error the current way? Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. UPDATE 12/7/2010 Error on site has been fixed, you can no longer view it from my site.

• Not able to add PC and synchronise files with Ubuntu One

  - by Ryan Hawthorne

  I have tried to add my PC to my Ubuntu One account 3 or 4 times: while I log in successfully in the Ubuntu One interface (after deleting my Ubuntu One password in 'passwords'), my folders don't give me an option to synchronise. I don't get the pink bar saying 'these folders cannot be synchronised'; I get nothing at all, no option. The second time I tried it seemed to work – but then it stopped working again.

• Is a simple iPhone app more appealing to users than a mobile website?

  - by Ryan

  My client wants to do an iPhone app because she's found that people are significantly more likely to use the iPhone app over a mobile optimized site. The iPhone app is very simple - it just displays a couple images and some text. As a programmer I'd much rather do a mobile site given the simple nature of the content. From a technical perspective I feel that it's overkill to use an iPhone app in this situation. Does it make sense to build an iPhone when a mobile site would suffice, simply because your users would much rather it be an iPhone app? Is there anyway to easily convince users that a mobile site is just as easy to use?
