  • CSS float problems, works in IE, doesn't work in Chrome/FF.. I'm probably doing something wrong

    - by user1003916
    I'm not terribly well-versed in CSS.. and don't know all of the major quirks yet. Maybe someone can help me. I've set up an image showing my code, a diagram of my DIVs, and examples of how it looks in IE versus Chrome/FF Can someone direct me to the proper way to go about this? It works fine in IE, but in Chrome and FF, one of the images is escaping its container, and the "content block" as I call it is going underneath the image it's supposed to be next to. Each of the components has a css class despite my diagram saying there's no css.. currently there's just some basic styling for those (padding, text-indent, etc). Thank you

  • PHP what is faster to use

    - by user1631500
    What is faster / better to use? To put html into variables and print them later, or to just html print / echo print the content based on condition? EXAMPLE 1:(html into variables) if(!isset($_SESSION['daddy'])) { $var = "<span class='something'>Go here:<a href='#'>Click</a></span> <span class='something'>Go here:<a href='#'>Click</a></span>" } else { $one=$_SESSION["one"]; $two=$_SESSION["two"]; $three=$_SESSION["three"]; $var = You are cool enough to view the content; } echo $var; EXAMPLE 2:(print based on condition) if(!isset($_SESSION['daddy'])) { $var = 1; } else { $one=$_SESSION["one"]; $two=$_SESSION["two"]; $three=$_SESSION["three"]; $var = 0; } if ($var==1) { ?> <span class='something'>Go here:<a href='#'>Click</a></span> <span class='something'>Go here:<a href='#'>Click</a></span <?php } else { ?> You are cool enough to view the content. <?php } ?>

  • Given a main function and a cleanup function, how (canonically) do I return an exit status in Bash/Linux?

    - by Zac B
    Context: I have a bash script (a wrapper for other scripts, really), that does the following pseudocode: do a main function if the main function returns: $returncode = $? #most recent return code if the main function runs longer than a timeout: kill the main function $returncode = 140 #the semi-canonical "exceeded allowed wall clock time" status run a cleanup function if the cleanup function returns an error: #nonzero return code exit $? #exit the program with the status returned from the cleanup function else #cleanup was successful .... Question: What should happen after the last line? If the cleanup function was successful, but the main function was not, should my program return 0 (for the successful cleanup), or $returncode, which contains the (possibly nonzero and unsuccessful) return code of the main function? For a specific application, the answer would be easy: "it depends on what you need the script for." However, this is more of a general/canonical question (and if this is the wrong place for it, kill it with fire): in Bash (or Linux in general) programming, do you typically want to return the status that "means" something (i.e. $returncode) or do you ignore such subjectivities and simply return the code of the most recent function? This isn't Bash-specific: if I have a standalone executable of any kind, how, canonically should it behave in these cases? Obviously, this is somewhat debatable. Even if there is a system for these things, I'm sure that a lot of people ignore it. All the same, I'd like to know. Cheers!

    I am trying to write a small function that will allow a user to submit a specific youtube channel url, and then return the number of views on the channel.

  • "lock request time out period exceeded" Error When Trying to See DB Hierarchies

    - by Lloyd Banks
    I have a DB that I can run basic queries (albeit much slower than normal) off of. When I try to see the hierarchy trees for tables, views, or procedures in SSMS Object Explorer, I get the "lock request time out period exceeded". My Report Server reports that run off of objects in this DB are no longer completing. Jobs associated with procedures stored on this DB also do not run. I tried using sp_who2 to find and kill all connections on the DB. This has not solved the problem. What is going on here? How can I resolve this?

  • XML\Jquery create listings based on user selection

    - by Sirius Mane
    Alright, so what I need to try and accomplish is having a static web page that will display information pulled from an XML document and render it to the screen without refreshing. Basic AJAX stuff I guess. The trick is, as I'm trying to think this through I keep coming into 'logical' barriers mentally. Objectives: -Have a chart which displays baseball team names, wins, losses, ties. In my XML doc there is a 'pending' status, so games not completed should not be displayed.(Need help here) -Have a selection list which allows you to select a team which is populated from XML doc. (done) -Upon selecting a particular team from the aforementioned selection list the page should display in a separate area all of the planned games for that team. Including pending. Basically all of the games associated with that team and the dates (which is included in the XML file). (Need help here) What I have so far: HTML\JS <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="batty.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html;

  • Program crash for array copy with ifort

    - by Stefano Borini
    This program crashes with Illegal instruction: 4 on MacOSX Lion and ifort (IFORT) 12.1.0 20111011 program foo real, pointer :: a(:,:), b(:,:) allocate(a(5400, 5400)) allocate(b(5400, 3600)) a=1.0 b(:, 1:3600) = a(:, 1:3600) print *, a print *, b deallocate(a) deallocate(b) end program The same program works with gfortran. I don't see any problem. Any ideas ? Unrolling the copy and performing the explicit loop over the columns works in both compilers. Note that with allocatable instead of pointer I have no problems. The behavior is the same if the statement is either inside a module or not. I confirm the same behavior on Linux using ifort (IFORT) 12.1.3 20120130.

  • can't get rid of top and bottom drop shadows

  • Automatic open Colorbox modal window

    - by user1631168
    I'm using the Colorbox module in Drupal 7. I'm opening an external website. I can make it work with a link. Click here, then click the "colorbox popup" link at the bottom, middle column. The client would like this to open automatically when the page opens. I've created a block and added the following code (from the colorbox site). <script type="text/javascript"> // Display a welcome message on first visit, and set a cookie that expires in 30 days: if (document.cookie.indexOf('visited=true') === -1) { var expires = new Date(); expires.setDate(expires.getDate()+30); document.cookie = "visited=true; expires="+expires.toUTCString(); jQuery.colorbox({html:"http://join.raretearepublic.com/popup/", width:887, height:638}); } </script> But it does not work. Any help would be greatly appreciated.

  • PHP Math issue with negatives [closed]

    - by user1269625
    Possible Duplicate: PHP negatives keep adding I have this code here.... $remaining = 0; foreach($array as $value=>$row){ $remaining = $remaining + $row['remainingbalance']; } What its doing is that it is going through all the remaining balances in the array which are -51.75 and -17.85 with the code above I get -69.60 which is correct. But I am wondering how when its two negatives if they could subtract? Is that possible? I tried this $remaining = 0; foreach($clientArrayInvoice as $value=>$row){ $remaining = $remaining + abs($row['remainingbalance']); } but it gives me 69.60 without the negative. Anyone got any ideas? my goal is to take -51.75 and -17.85 and come up with -33.90 only when its a negative to do subtract. otherwise add

  • NameClaimType in ClaimsIdentity from SAML

    - by object88
    I am attempting to understand the world of WIF in context of a WCF Data Service / REST / OData server. I have a hacked up version of SelfSTS that is running inside a unit test project. When the unit tests start, it kicks off a WCF service, which generates my SAML token. This is the SAML token being generated: <saml:Assertion MajorVersion="1" MinorVersion="1" ... > <saml:Conditions>...</saml:Conditions> <saml:AttributeStatement> <saml:Subject> <saml:NameIdentifier Format="EMAIL">4bd406bf-0cf0-4dc4-8e49-57336a479ad2</saml:NameIdentifier> <saml:SubjectConfirmation>...</saml:SubjectConfirmation> </saml:Subject> <saml:Attribute AttributeName="emailaddress" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>[email protected]</saml:AttributeValue> </saml:Attribute> <saml:Attribute AttributeName="name" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>bob</saml:AttributeValue> </saml:Attribute> </saml:AttributeStatement> <ds:Signature>...</ds:Signature> </saml:Assertion> (I know the Format of my NameIdentifier isn't really EMAIL, this is something I haven't gotten to cleaning up yet.) Inside my actual server, I put some code borrowed from Pablo Cabraro / Cibrax. This code seems to run A-OK, although I confess that I don't understand what's happening. I note that later in my code, when I need to check my identity, Thread.CurrentPrincipal.Identity is an instance of Microsoft.IdentityModel.Claims.ClaimsIdentity, which has a claim for all the attributes, plus a nameidentifier claim with the value in my NameIdentifier element in saml:Subject. It also has a property NameClaimType, which points to "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name". It would make more sense if NameClaimType mapped to nameidentifier, wouldn't it? How do I make that happen? Or am I expecting the wrong thing of the name claim? Thanks!

  • POST method getting converted to GET in IE-9

    - by Sri127
    I have this line of code in my JSP. (I'm using struts 1.3) <html:form action="screening/mine.do" method="post"> . . . </html:form When the action corresponding to mine.do is invoked (using struts-config.xml), the page is getting submitted as GET instead of POST. All the request parameters including the required ones are getting lost due to this. This issue occcurs only in IE-9. The response remains as POST when I use other versions of IE or any other browsers. How do I make the response to remain as POST in IE-9 ? EDIT : I observed one more issue in this. Whenever the page is rendered in a new window, this issue occurs. Other places, the POST works fine in IE-9. Also, this issue occurs in Win7/IE-8, but works absolutely fine in XP/IE-8. Is there something to do with the OS as well??? Any solutions would be useful. Thanks!!

  • Convert String containing several numbers into integers

    - by GobiasKoffi
    I realize that this question may have been asked several times in the past, but I am going to continue regardless. I have a program that is going to get a string of numbers from keyboard input. The numbers will always be in the form "66 33 9" Essentially, every number is separated with a space, and the user input will always contain a different amount of numbers. I'm aware that using 'sscanf' would work if the amount of numbers in every user-entered string was constant, but this is not the case for me. Also, because I'm new to C++, I'd prefer dealing with 'string' variables rather than arrays of chars.

  • Invoke Python modules from Java

    - by user36813
    I have a Python interface of a graph library written in C - igraph (the name of library). My need is to invoke the python modules pertaining to this graph library from Java code. It goes like this, the core of library is in c. This core has been imported into Python and interfaces to the functions embedded in core are available in Python. My project's rest of the code is in Java and hence I would like to call the graph functions by Java as well. Jython - which lets you invoke python modules with in Java was an option.I went on trying Jython to discover that it will not work in my case as the core code is in C and Jython wont support anything that is imported as a c dll in python code.I also thought of opting for the approach of calling graph routines directly in c. That is without passing through Python code. I am assuming there must be something which lets you call c code from Java, how ever I am not good in C hence I did not go for it. My last resort seems to execute Python interpreter from command line using Java. But that is a dirty and shameless. Also to deal with the results produced by Python code I will have to write the results in a file and read it back in java. Again dirty way. Is there something that any one can suggest me? Thanks to every one giving time. Thanks Igal for answering. I had a look at it. At first glance it appears as if it is simply calling the python script. Jep jep = new Jep(false, SCRIPT_PATH, cl); jep.set("query", query); jep.runScript(SCRIPT_PATH + file); jep.close(); Isnt it very similar to what we would do if called the python interpreter from command line through a Java code. Runtime runtime = Runtime.getRuntime(); Process proc = runtime.exec("python test.py"); Concern is how do I use the results generated by Python script. The naive way is to write them to file and read it back in Java. I am searching for a smarter approach.Thanks for suggestion anyway.

  • Beware when using .NET's named pipes in a windows forms application

    - by FransBouma
    Yesterday a user of our .net ORM Profiler tool reported that he couldn't get the snapshot recording from code feature working in a windows forms application. Snapshot recording in code means you start recording profile data from within the profiled application, and after you're done you save the snapshot as a file which you can open in the profiler UI. When using a console application it worked, but when a windows forms application was used, the snapshot was always empty: nothing was recorded. Obviously, I wondered why that was, and debugged a little. Here's an example piece of code to record the snapshot. This piece of code works OK in a console application, but results in an empty snapshot in a windows forms application: var snapshot = new Snapshot(); snapshot.Record(); using(var ctx = new ORMProfilerTestDataContext()) { var customers = ctx.Customers.Where(c => c.Country == "USA").ToList(); } InterceptorCore.Flush(); snapshot.Stop(); string error=string.Empty; if(!snapshot.IsEmpty) { snapshot.SaveToFile(@"c:\temp\generatortest\test2\blaat.opsnapshot", out error); } if(!string.IsNullOrEmpty(error)) { Console.WriteLine("Save error: {0}", error); } (the Console.WriteLine doesn't do anything in a windows forms application, but you get the idea). ORM Profiler uses named pipes: the interceptor (referenced and initialized in your application, the application to profile) sends data over the named pipe to a listener, which when receiving a piece of data begins reading it, asynchronically, and when properly read, it will signal observers that new data has arrived so they can store it in a repository. In this case, the snapshot will be the observer and will store the data in its own repository. The reason the above code doesn't work in windows forms is because windows forms is a wrapper around Win32 and its WM_* message based system. Named pipes in .NET are wrappers around Windows named pipes which also work with WM_* messages. Even though we use BeginRead() on the named pipe (which spawns a thread to read the data from the named pipe), nothing is received by the named pipe in the windows forms application, because it doesn't handle the WM_* messages in its message queue till after the method is over, as the message pump of a windows forms application is handled by the only thread of the windows forms application, so it will handle WM_* messages when the application idles. The fix is easy though: add Application.DoEvents(); right before snapshot.Stop(). Application.DoEvents() forces the windows forms application to process all WM_* messages in its message queue at that moment: all messages for the named pipe are then handled, the .NET code of the named pipe wrapper will react on that and the whole process will complete as if nothing happened. It's not that simple to just say 'why didn't you use a worker thread to create the snapshot here?', because a thread doesn't get its own message pump: the messages would still be posted to the window's message pump. A hidden form would create its own message pump, so the additional thread should also create a window to get the WM_* messages of the named pipe posted to a different message pump than the one of the main window. This WM_* messages pain is not something you want to be confronted with when using .NET and its libraries. Unfortunately, the way they're implemented, a lot of APIs are leaky abstractions, they bleed the characteristics of the OS objects they hide away through to the .NET code. Be aware of that fact when using them :)

  • Adding Facebook Open Graph Tags to an MVC Application

    - by amaniar
    If you have any kind of share functionality within your application it’s a good practice to add the basic Facebook open graph tags to the header of all pages. For an MVC application this can be as simple as adding these tags to the Head section of the Layouts file.<head> <title>@ViewBag.Title</title> <meta property="og:title" content="@ViewBag.FacebookTitle" /> <meta property="og:type" content="website"/> <meta property="og:url" content="@ViewBag.FacebookUrl"/> <meta property="og:image" content="@ViewBag.FacebookImage"/> <meta property="og:site_name" content="Site Name"/> <meta property="og:description" content="@ViewBag.FacebookDescription"/></head>  These ViewBag properties can then be populated from any action: private ActionResult MyAction() { ViewBag.FacebookDescription = "My Actions Description"; ViewBag.FacebookUrl = "My Full Url"; ViewBag.FacebookTitle = "My Actions Title"; ViewBag.FacebookImage = "My Actions Social Image"; .... } You might want to populate these ViewBag properties with default values when the actions don’t populate them. This can be done in 2 places. 1. In the Layout itself. (check the ViewBag properties and set them if they are empty) @{ ViewBag.FacebookTitle = ViewBag.FacebookTitle ?? "My Default Title"; ViewBag.FacebookUrl = ViewBag.FacebookUrl ?? HttpContext.Current.Request.RawUrl; ViewBag.FacebookImage = ViewBag.FacebookImage ?? "http://www.mysite.com/images/logo_main.png"; ViewBag.FacebookDescription = ViewBag.FacebookDescription ?? "My Default Description"; }  2. Create an action filter and add it to all Controllers or your base controller. public class FacebookActionFilterAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var viewBag = filterContext.Controller.ViewBag; viewBag.FacebookDescription = "My Actions Description"; viewBag.FacebookUrl = "My Full Url"; viewBag.FacebookTitle = "My Actions Title"; viewBag.FacebookImage = "My Actions Social Image"; base.OnActionExecuting(filterContext); } } Add attribute to your BaseController. [FacebookActionFilter] public class HomeController : Controller { .... }

If you’re building a Windows 8 app and want a fast and easy path to creating backend cloud services, this preview provides the capabilities you need. You to take advantage of the cloud to build and deploy modern apps for Windows 8 devices in anticipation of general availability on October 26th. Subsequent preview releases will extend support to iOS, Android, and Windows Phone. Features The preview makes it fast and easy to create cloud services for Windows 8 applications within minutes. Here are the key benefits:  Rapid development: configure a straightforward and secure backend in less than five minutes. Create modern mobile apps: common Windows Azure plus Windows 8 scenarios that Windows Azure Mobile Services preview will support include:  Automated Service API generation providing CRUD functionality and dynamic schematization on top of Structured Storage Structured Storage with powerful query support so a Windows 8 app can seamlessly connect to a Windows Azure SQL database Integrated Authentication so developers can configure user authentication via Windows Live Push Notifications to bring your Windows 8 apps to life with up to date and relevant information Access structured data: connect to a Windows Azure SQL database for simple data management and dynamically created tables. Easy to set and manage permissions. Pricing One of the key things that we’ve consistently heard from developers about using Windows Azure with mobile applications is the need for a low cost and simple offer. The simplest way to describe the pricing for Windows Azure Mobile Services at preview is that it is the same as Windows Azure Websites during preview. What’s FREE? Run up to 10 Mobile Services for free in a multitenant environment Free with valid Windows Azure Free Trial 1GB SQL Database Unlimited ingress 165MB/day egress  What do I pay for? Scaling up to dedicated VMs Once Windows Azure Free Trial expires - SQL Database and egress     Getting Started To start using Mobile Services, you will need to sign up for a Windows Azure free trial, if you have not done so already.  If you already have a Windows Azure account, you will need to request to enroll in this preview feature. Once you’ve enrolled, this getting started tutorial will walk you through building your first Windows 8 application using the preview’s services. The developer center contains more resources to teach you how to: Validate and authorize access to data using easy scripts that execute securely, on the server Easily authenticate your users via Windows Live Send toast notifications and update live tiles in just a few lines of code Our pricing calculator has also been updated for calculate costs for these new mobile services.

  • Windows Azure Recipe: High Performance Computing

    - by Clint Edmonson
    One of the most attractive ways to use a cloud platform is for parallel processing. Commonly known as high-performance computing (HPC), this approach relies on executing code on many machines at the same time. On Windows Azure, this means running many role instances simultaneously, all working in parallel to solve some problem. Doing this requires some way to schedule applications, which means distributing their work across these instances. To allow this, Windows Azure provides the HPC Scheduler. This service can work with HPC applications built to use the industry-standard Message Passing Interface (MPI). Software that does finite element analysis, such as car crash simulations, is one example of this type of application, and there are many others. The HPC Scheduler can also be used with so-called embarrassingly parallel applications, such as Monte Carlo simulations. Whatever problem is addressed, the value this component provides is the same: It handles the complex problem of scheduling parallel computing work across many Windows Azure worker role instances. Drivers Elastic compute and storage resources Cost avoidance Solution Here’s a sketch of a solution using our Windows Azure HPC SDK: Ingredients Web Role – this hosts a HPC scheduler web portal to allow web based job submission and management. It also exposes an HTTP web service API to allow other tools (including Visual Studio) to post jobs as well. Worker Role – typically multiple worker roles are enlisted, including at least one head node that schedules jobs to be run among the remaining compute nodes. Database – stores state information about the job queue and resource configuration for the solution. Blobs, Tables, Queues, Caching (optional) – many parallel algorithms persist intermediate and/or permanent data as a result of their processing. These fast, highly reliable, parallelizable storage options are all available to all the jobs being processed. Training Here is a link to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure HPC Scheduler (3 labs)  The Windows Azure HPC Scheduler includes modules and features that enable you to launch and manage high-performance computing (HPC) applications and other parallel workloads within a Windows Azure service. The scheduler supports parallel computational tasks such as parametric sweeps, Message Passing Interface (MPI) processes, and service-oriented architecture (SOA) requests across your computing resources in Windows Azure. With the Windows Azure HPC Scheduler SDK, developers can create Windows Azure deployments that support scalable, compute-intensive, parallel applications. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

  • How do you move files to Windows Server 2008 cloud server from local computer?

    - by Mausimo
    I recently setup a Windows 2008 R2 server on Amazon EC2. I now want to move an application I created on my local desktop to this server. However, having never done this before I have no idea how to transfer files from my local desktop to the online server. What is the standard convention for transferring files from local machine to the server? As a side note, why can I not download the .NET framework 4 .exe file? Clicking the download link does nothing... (it is already a trusted site)

  • How to recover data from a partially overwritten partition

    - by shredder12
    By mistake, I configured a 900GB partition to be part of a 50GB raid. The sync is complete and my understanding is that only the first 50GB of the bigger partition is overwritten. How do I recover the rest of the data? When I try to mount this partition by identifying it as ext3, it mounts only the 50GB overwritten space. This partition was earlier divided into various logical volumes(all ext3 filesystems) through LVM. Any suggestions?

  • APC and "apc.gc_ttl" :: How Low is Too Low?

    - by nojak
    I currently have my apc.gc_ttl set to 600 to help keep fragmentation down. Since apc.gc_ttl just sets the time on cache for garbage collection, I don't see any harm in keeping it this low. However, I'm new to APC, and have seen many configurations online that use a 3600 TTL, which seems quite long to me for garbage collection cache... Is 600 too low? Is 3600 too high? As I'm sure mileage varies on this setup, is there a good rule of thumb to follow?
