  • How can I fix the website's splash page to work in IE8 and below?

    - by Abriel
    I have been trying to figure out for the longest time how I can get the splash page on this website to work correctly in IE8 and below? Right now, it works on all the other browsers (Firefox, Chrome, Safari). Here is the website: http://gds.parkland.edu/student/fall10/gds220/ashipley/p2/final_revised/index.html jQuery code: /* Sliding Affect Splash Page */ $(function() { $('.box').each(function() { var $this = $(this); $.data(this, 'css', { width: $this.css('width'), background: $this.css('background-image') }); }); }); function restore() { $('.box').each(function() { var orig = $.data(this, 'css'); $(this).animate({ width: orig.width },{queue:false}); $(this).css({backgroundImage: orig.background}); }); } /* box 1 */ function boxHover(){ $('.box').stop().animate({'width' : '596px'},{queue:false}); } function box1master(){ $('.box2').css({backgroundImage: 'url(images/splash/zatgun_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/zatgun_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/zatgun_bottom.jpg)'}); } function box2master(){ $('.box1').css({backgroundImage: 'url(images/splash/bryan_top.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/bryan_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/bryan_bottom.jpg)'}); } function box3master(){ $('.box1').css({backgroundImage:'url(images/splash/galleries_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/galleries_midtop.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/galleries_bottom.jpg)'}); } function box4master(){ $('.box1').css({backgroundImage: 'url(images/splash/contact_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/contact_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/contact_midbottom.jpg)'}); } $(document).ready(function(){ $('.box1').hover(function(){ boxHover(); box1master(); }, function(){ restore(); }); $('.box2').hover(function(){ boxHover(); box2master(); }, function(){ restore(); }); $('.box3').hover(function(){ boxHover(); box3master(); }, function(){ restore(); }); $('.box4').hover(function(){ boxHover(); box4master(); }, function(){ restore(); }); }); I wonder if I could change the spacing in-between each of the boxes using jQuery or if I somehow have to do this in the CSS/HTML?

  • Dojo slider: update value dynamically

    - by xApple
    I am building an application where the user browses certain objects by scrolling and zooming. To change the zoom level I have successfully implemented a "dijit.form.HorizontalSlider" object. Every time the user changes the position of the silder, I can catch the "onChange" call and do something with that. However, the user can also zoom-in by double clicking inside the view zone, at which point the slider should change position automatically to reflect the new zoom level. My question is the following: what function or method should I call in my javascript to update the position of a dojo silder ? Here is the code that creates the silder object: var zoomSlider = new dijit.form.HorizontalSlider({ name: "zoom_slider", id: "zoom_slider", value: 0, minimum: 0, maximum: 19, discreteValues: 20, intermediateChanges: false, style: "width: 160px;", onChange: function(value) { brwsr.view.zoomTo(value); } }, "zoom_slider"); navbox_silder.appendChild(zoomSlider.domNode);

  • facebook iframe application gives null GET/POST

    - by misterjinx
    hey everybody, I came up to something really strange with a facebook iframe application. I don't know why but my global supervariables $_GET and $_POST are empty (nulls actually)! As far as i know, when using iframe for doing applications all the specific facebook variables are kept inside the $_GET variable. But for some reason now I don't have anything. I don't know what might be the problem. And as this wouldn't be enough, when i submit a form using POST as method, my $_POST variable is also null! What you guys think might be the problem? I've spent half a day trying to figure this out, but i didn't get any result.

  • Hyper-V 2008 R2 synthetic networking stops working with linux 2.6.32.15

    - by luxifer
    Hi there, so I thought I'd give Hyper-V on Windows Server 2008 R2 Enterprise a try on my Homeserver (yes, it's legit... got it from msdnaa). First thing to throw at it was my firewall which runs IPFire. This distribution currently uses the kernel version 2.6.32.15 and comes with the Hyper-V drivers. So I enabled them and at first they work just fine but after a few minutes they just fail. There are no packages going in or out anymore until I reboot the VM but sometimes even that won't work so the VM just keeps "Stopping" like forever. Emulated networking works fine but it slow and uses more CPU. That way my firewall routes slower than when running under virtualbox on an atom N270. My server has an E6750; VM is limited to 25%, but that should still outperform this atom CPU especially since it's never going anywhere near 100% CPU load, so give me a break! A quick google search led me to people having the same problem (even with other distributions and kernel versions that include those drivers) but no solution yet... I already found this but I can't quite follow the author on the part where he solved the issue - especially since I need two virtual nics for my firewall distro to work (obviously one internal and one external) What am I missing here?

  • sed works properly in SSH, not in PHP

    - by David
    So, I have the following line that I run in PHP with exec($addPHPtags); $addPHPtags = "/bin/sed -i '/<BODY BGCOLOR=\"#FFFFFF\">/ a\ <?php \n ?> '" . $instance['file'] . " 2>&1"; I'd expect that command to find the key and append it with a php tag. However, when I run it in PHP, I get the following error if I trap command output: [0] => /bin/sed: -e expression #1, char 39: unknown command: `?' However, if I run the same command in SSH, it works completely fine: /bin/sed -i '/<BODY BGCOLOR=\"#FFFFFF\">/ a\ <?php \n ?>' file.php I'm out of ideas, I've tried various alternatives but to no avail. Any help ? Thanks.

  • Pass quoted argument string to Start-Process in PowerShell

    - by Luke Puplett
    Hello I'm trying to very simply run an executable and pass a file path in as the first argument. In DOS, this would be the command: import.exe "C:\Some Path\With\Spaces.txt" By placing the path in quotes, the path is correctly parsed as the first token into the executable. In PowerShell I'm using this: $feeds = dir 'T:\Documents\Company\Product Development\Data foreach ($feed in $feeds) { start -FilePath import.exe -ArgumentList $feed.FullName } The problem with the Start-Process cmdlet in PowerShell is that it uses a string array for arguments, so the path is broken up and sent to the executable as separate tokens. Quotes in PowerShell force $feed.FullName to be treated literally. Double quotes "" make PowerShell not see anything in the argument list. "The argument is null or empty." it tells me. I expect that this is a known headache and has had a known workaround from day one. Thanks Luke

  • LDAP System Authentication in Ubuntu

    - by andrew
    Hi, I'm having a bit of an issue with system authentication against LDAP in Ubuntu. The LDAP server is OpenLDAP on Ubuntu 10.10, and the client is Ubuntu 10.10 also. I've set up the client by following the "LDAP Authentication" steps at https://help.ubuntu.com/10.10/serverguide/C/openldap-server.html apt-get install libnss-ldap; auth-client-config -t nss -p lac_ldap; pam-auth-update I've done these steps on the server and been able to see LDAP users when running getent passwd. Doing the same steps on the client, getent passwd does not return any LDAP users. Any ideas?

  • Error during SSL installation cPanel/WHM

    - by baswoni
    I have a dedicated server and I am using the install wizard via WHM to install an SSL certificate. I have the following keys: Certificate key RSA private key CA certificate I paste these three elements into the wizard along with the domain, IP address and username but I get this error: SSL install aborted due to error: Unable to save certificate key. Certificate verification passed Have I missed a step? I have given it another go to make sure I am copying and pasting the info correctly and I am now getting the following error: SSL install aborted due to error: Sorry, you must have a dedicated ip to use this feature for the user: username! If you are intending to install a shared certificate you must use the username "nobody" for security and bandwidth reporting reasons. Even though I am using a dedicated IP address, I am getting this problem. I thought I would also add that this SSL certificate has been installed on a shared hosting environment with my previous hostig provider. The account with them is still active, however the domain and its contents now reside on the dedicated server - could this cause problems?

  • What does transactions per seconds for a load balancer mean

    - by Anurag
    I was looking at the product matrix of webmux 592G(load balancer). It says maximum connections per sec = 2.8M Maximum number of transactions = 100,000 What does the above numbers mean. Does above means that load balancer can have 2.8M connections open but only 100K of them will be active per seconds. Also incase any one has used webmux 592G do you guys know in practice how many connections it can have open and what qps it can serve

  • Which Large File System Format to use for USB Flash drive compatible with Ubuntu/Mac/Windows?

    - by wajiw
    I've had this problem for a long time and can't find a solution. I switch between the 3 OSes all the time and use a 1TB USB Drive to do so. I can't seem to find a format that is compatible across all systems that handles large files (at least 8-9 GB). Does anyone have a solution for this? Recently I've tried exFat but that messes up the filesystem when trying to read on windows after adding files from Ubuntu (using the fuse driver). The OSes currently I'm using are Windows Vista/7, Mac OS X (10.6.5) and Ubuntu 10.10

  • Installation is forbidden by system policy

    - by Frost
    Note: I'm posting this here on Superuser as I think the issue is more related to the Windows Installer than the game itself. My friend is having trouble installing Company of Heroes and CoH: Opposing fronts under Windows 7. A couple of percent into the installation, when the C/C++ runtime is being installed, the install fails with the following message: An error occured while installing the Windows Installer package "C:\Users\...\AppData\Local\Temp\...\...\vcredist.msi". Error code 10212:00000659: MsiInstallProductW returned 00000659: This installation is forbidden by system policy. Contact your system administrator. We have tried: Making sure that any previous installations have been completely removed, including searching and deleting any files/folders/registry entries matching "THQ" (the publisher) and "Relic" (the developer). Installing into a brand new user account Running Setup.exe as administrator Running Compatibility check for Setup.exe, which suggested Windows XP but failed when trying those settings out Does anyone know what might be the cause of the system policy error?

  • Two screens hooked to one laptop

    - by mplacona
    Hi, I'm thinking of getting rid of my desktop, and using my (much better) laptop instead. I'm only wondering if I would be able to hook the two screens I have with it, so I'd end up with three screens. I've seen people doing it to desktops, but am not sure the same could be accomplished with a laptop. My laptop is a sony vaio, and it's got both a VGA output, and an HDMI output. It'd be great is I could simply hook two screens to it, and have three independent screens (not mirrored). on my desktop, I have pretty much the same thing, but with an extra DVI port. I connect the DVI to one screen, and the VGA to an older one. Trying to connect anything to the HDMI simply mirrors whatever is on the DVI (I've tried it a long time ago) So I was wondering if with the laptop I'd be able to do it, and end up with three independent screens. I don't know if there's anything else I could be using instead (i.e. any extra hardware), so recommendations are more than welcome. Thanks in advance, Marcos

  • Who would be the most efficacious Patron Saint of Programmers? [closed]

    - by Peter Turner
    The purpose of this question is to find someone out there to intercede for us and help our coding (not to magically align the bytes), to inspire our daily grind of software development by their lives of heroic virtue, to unite us under a common patron and to keep us on the straight and narrow path (i.e. don't be evil). In days of yore, the professional guilds had a patron saint. Regardless of whether we have a higher tendency to be atheists or not, who would you choose as the patron saint of programmers and what would be your criteria? Some people have chosen St. Isidore of Seville, but he's more like the patron saint of Wikipedia. If you're not Catholic please don't hesitate to nominate someone, just say what your criteria is. At the very least they should be dead and have lived a life of heroic virtue - or have died trying. It's a very pragmatic and noble custom which I heartily encourage. But if you find the practice off-putting, please don't be offended. I only mean to ask this question to other like minded programmers, which I have reason to believe exist. If you add a picture and a maybe make up a prayer that'd be excellent. It doesn't have to be gilded, illuminated and rhyme, although that would be sweet.

  • Can it be a good idea to create a new table for each client of a webapp?

    - by Will
    This is semi-hypothetical, and as I've no experience in dealing with massive database tables, I have no idea if this is horrible for some reason. On to the situation: Imagine a web based application - lets say accounting software - which has 20,000 clients and each client has 1000+ entries in a table. That's 20 million rows which I know can certainly slow down complex queries. In a case like this, does it make more sense to create a new table in the database for each client? How do databases react to having 20k (or more!) tables?

  • Interview Questions [closed]

    - by Pemdas
    Possible Duplicate: What techniques do you use when interviewing developers? Nearly every SE interviewing process has some sort of coding exercise to prove that the interviewee can actually write code. More often then not, the exercise also hopes to demonstrate that the interviewee can solve problems. However, this is often not sufficient enough to determine if the interviewee can actually design software. What are some effective ways to determine if an interviewee understands the basic concepts of design such as abstraction, interface design, thread management, ...ect?

  • Is MVC now the only way to write PHP?

    - by JasonS
    Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

  • unix career in programming

    - by mnunna
    I am currently working on a HP-UX platform and my role as a prod support team member involves mostly to write shell scripts. But I want to branch out into core systems programming in unix. A quick search on the internet threw no "unix systems programming jobs" in my area. I'm confused as what to do. I really would like to continue with unix as my core competency, but unix jobs are mostly of sys admin/ prod support type, of which I do not want a part of. Can anyone of you give me an informed advice on the career oppurtinities that await unix professionals?? Any advice would be appreciated.

  • When is it better to offload work to the RDBMS rather than to do it in code?

    - by GeminiDomino
    Okay, I'll cop to it: I'm a better coder than I am at databases, and I'm wondering where thoughts on "best practices" lie on the subject of doing "simple" calculations in the SQL query vs. in the code, such as this MySQL example (I didn't write it, I just have to maintain it!) -- This returns the username, and the users age as of the last event. SELECT u.username as user, IF ((DAY(max(e.date)) - DAY(u.DOB)) &lt; 0 , TRUNCATE(((((YEAR(max(e.date))*12)+MONTH(max(e.date))) -((YEAR(u.DOB)*12)+MONTH(u.DOB)))-1)/12, 0), TRUNCATE((((YEAR(max(e.date))*12)+MONTH(max(e.date))) - ((YEAR(u.DOB)*12)+MONTH(u.DOB)))/12, 0)) AS age FROM users as u JOIN events as e ON u.id = e.uid ... Compared to doing the "heavy" lifting in code: Query: SELECT u.username, u.DOB as dob, e.event_date as edate FROM users as u JOIN events as e ON u.id = e.uid code: function ageAsOfDate($birth, $aod) { //expects dates in mysql Y-m-d format... list($by,$bm,$bd) = explode('-',$birth); list($ay,$am,$ad) = explode('-',$aod); //Insert Calculations here ... return $Dy; //Difference in years } echo "Hey! ". $row['user'] ." was ". ageAsOfDate($row['dob'], $row['edate']) . " when we last saw him."; I'm pretty sure in a simple case like this it wouldn't make much difference (other than the creeping feeling of horror when I have to make changes to queries like the first one), but I think it makes it clearer what I'm looking for. Thanks!

  • Why can't I install 10.04 on a system that already has 8.04?

    - by Android Eve
    Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now). But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help. I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted as "busy" or "locked". Any idea how to solve this problem?

  • Does it make the game more fun when the user is forced to progress thru the levels sequentially rather than letting them pick and play?

    - by BeachRunnerJoe
    Hello. For the first time in my game, I'm stuck with a real design dilemma. I guess that's a good thing ;) I'm building a word puzzle game that has five levels, each with 30 puzzles. Currently, the user has to solve one puzzle at a time before moving to the next. However, I'm finding the user occasionally gets stuck on a puzzle, at which point they can no longer play until they solve it. This is obviously bad because many people will just quit playing the game and delete the app since they get frustrated and can't play any other puzzles until the current puzzle is solved. The only elegant solution I can find to helping the player get unstuck is changing the design of the game to allow the users to pick any puzzle to play at any time. This way, if they get stuck, they can come back to it later and at least they have other puzzles to play in the meantime. It's my opinion, however, that this new flow design doesn't make the game as fun as the original flow design where the player has to complete a puzzle before moving to the next. To me, it's like anything else, when you only have one of something, it's more enjoyable, but when you have 30 of something, it's far less enjoyable. In fact, when I present the user with 30 puzzles to choose from that they need to solve before unlocking the next level, it almost seems as tho I'm making them feel like it's work they have to do. I even had a tester voluntarily tell me that being forced to complete a puzzle before moving to the next is more motivating. My questions are... Do you agree/disagree? Do you have any suggestions for how I can help the player get unstuck? Thanks so much in advance for your thoughts! EDIT: I should mention that I've already considered a few other solutions to helping the user get unstuck, but none of them seem like good ideas. They are... Add more hints: Currently, the user gets two hints per puzzle. If I increase the hint count, it only makes the game more easy and still leaves the possibility of the user getting stuck. Add a "Show Solution" button: This seems like a bad idea because it's my opinion this takes the fun out of the game for many people who would probably otherwise solve the puzzle if they didn't have the quick option to see the solution.

  • Best approach for unit enemy "awareness" in RTS?

    - by Phil
    I'm using Unity3d to develop an RTS/TD hybrid prototype game. What is the best approach to have "awareness" between units and their enemies? Is it sane to have every unit check the distance to every enemy and engage if within range? The approach I'm going for right now is to have a trigger sphere on every unit. If an enemy enters the trigger, the unit becomes aware of the enemy and starts distance checking. I'm imagining that this would save some unnecessary checks? What's the best practice here (if there's such a thing)? Thanks for reading.

Does anyone know why this is happening?
