  • Ruby equivalent of PHP's fopen() method

    - by lagrz
    I'm trying to find out if Ruby has en equivalent of php's fopen() method currently used like this: $fd = fopen("php://stdin", "r"); would that be using ARGV variable? Basically what I plan on doing is forward raw e-mail messages using the .procmailrc file which I already got working in a test php file, but the project requires the use of Ruby. Therefore I'm not 100% sure if using the ARGV variable would work or if somehow I need to capture the e-mail stream by some other means. Any help would be greatly appreciated. Thanks :)

  • Entity Framework mant to many insert

    - by Jacob
    I've been playing around with Entity Framework v2 and added some code to insert new entity with many to many relationship , lets say this entity is called meeting. I add hours to meeting : meeting.Hours.Add(hour); and I get different errors on different occasions On Update : Cannot insert the value NULL into column 'Meetings_Id', table 'Plan.dbo.MeetingHour'; column does not allow nulls. INSERT fails. The statement has been terminated. On Inset : An item with the same key has already been added. But the tricky party is that if I add this manually trough SQL Server Management Studio , I can update the entity with the same value , clearing it first (meeting.Hour.Clear()) Can't see what could be the problem , maybe entity model isn't mapped correctly ?

  • UIImages on UITableView?

    - by babu Kong
    what is the best method to display about 300 png images into a UITableView.. i dont wanna display them at the same time... i have 3 tableViewControllers that will each display about 100 imgaes..

  • Converting old WCF service to RIA one

    - by Artur
    Hi there, Currently I have a service that looks like: Some app <-- WCF Service <-- Business Logic <-- Entity Framework Model <-- SQL Database One of "some app" would be Silverlight, but there as well will be lots of other clients (mainly mobile devices). To me the greatest benefit of having RIA services is possibility of making ordinary (not asynchronous) calls from Silverlight. I wondered if there is an easy way of converting what I have so far to be a RIA service? I as well wonder if there is a point of doing so if I plan to use the same service for multiple platforms/clients? Any help/links would be greatly appreciated.

  • Mapping of memory addresses to physical modules in Windows XP

    - by Josef Grahn
    I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

  • Batch vs SQL statement

    - by AspOnMyNet
    a) A SQL statement is a single SQL command (for example, SELECT * FROM table1 or SET NOCOUNT ON). A batch on the other hand, is a number of SQL statements sent to the server for execution as a whole unit. The statements in the batch are compiled into a single execution plan. Batches are separated by the GO command So the only difference between SQL statement and a Batch is that each SQL statement is sent to server as a separate unit and thus is compiled separately from other SQL statements, while SQL statements in a Batch are compiled together? b) I assume one of major differences between a stored procedure and a Batch is that stored procedures are precompiled while Batches aren’t? thanx

  • How do I include 2 tables in LocalStorage?

    - by Noor
    I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

  • Getting ready to learn html5

    - by vtortola
    I'm a desktop application developer, and I plan learning html5, but as it's not released, there are (almost) no published books and not too much infomation for beginners on the web... I feel I should start with html4 and the current web development skills. I think I should start with html4, css, and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be still used when html5 is released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript?

  • What is a header? Especially, what are POST@GET headers?

    - by brilliant
    Hello, I've been trying to find a Python code that would log in to my Yahoo account from "Google App Engine". One supporter on "StackOverflow" gave me this three-step plan: Simulate normal login and save login page that you get; Save POST&GET headers with "Wireshark"; Compare login page with those headers and see what fields you need to include with your request; The problem here is that I have never used "Wireshark" before. Plus, I don't know what the POST&GET headers are. Can You, please, explain it to me (preferably with some example). Thank You.

  • Has anybody use javafx on CDC J9?

    - by 4NDR01D3
    Is that possible?? I mean, I have an already working project that runs in windows mobile using the J9 virtual machine for CDC. My user interface there is using AWT and it works fine and it looks OK, but been honest it doesn't take real advantage of the devices were is running... So I start reading about JavaFX and that looks really cool, but all that I see about mobiles there is applied to CLDC, MIDP, etc. but my application is already running on CDC J9 and I can't change this cause I'm using a Derby database on it. So, my plan is to code the GUI again, but keeping the logic of the application. So do you guys think javafx is the way to go? or, am I wasting my time learning javafx for this project. Thanks in advance, Gustavo.

  • Internet Explorer shows error when downloading excel file in SSL site

    - by Billy
    I get the following error when downloading excel file in SSL site: Internet Explorer cannot download xxxx.aspx from mysite.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. After googling, I suspect that it's the problem of the response header. I try the solution in this page and set the header: http://trac.edgewall.org/ticket/1020 HttpContext.Current.Response.AddHeader("Pragma", "no-cache"); HttpContext.Current.Response.CacheControl = "private"; But it doesn't work. Any suggestions?

  • Ajax call with jQuery in ASP.NET MVC does not pass parameters

    - by desmati
    The Route is: routes.MapRoute( "Ajax", // Route name "BizTalk/Services/{action}", // URL with parameters new { // Parameter defaults controller = "BizTalk" } ); My Controller is: public JsonResult AjaxTest(string s, int i, bool b) { return Json("S: " + s + "," + "I: " + i + "," + "B: " + b); } My jQuery Code: $(document).ready(function() { $("#btn_test").click(function() { var s = "test"; var i = 8; var b = true; $.ajax({ type: "POST", cache: false, url: "/BizTalk/Services/AjaxTest", data: { i: i, s: s, b: b }, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { } }); }); });

  • How do you make a UIBarButtonItem animation flip?

    - by Andrew Arrow
    In the iPod app on the iPhone there is a UIBarButtonItem in the upper right toolbar that flips between the song and track listings for the album. When you select the button, the button itself does a flip animation. Is there a way to do this with: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:[self superview] cache:YES]; Do I need to make a UIBarButtonItem with initWithCustomView vs. initWithImage to achieve this?

  • Backup & recovery of multiple MySQL databases (InnoDB & MyISAM)

    - by Cymon
    I am working on nightly and hourly backups of MySQL Databases. There are multiple MySQL databases which are either InnoDB or MyISAM (Note: Each database is either InnoDB or MyISAM for a reason). With the 2 different types I want to make sure I am grabbing everything that is needed for backup and recovery. Here is my current plan Nightly -mysqldump of each DB which is stored locally and remotely. Hourly -flush binary logs and store them locally and remotely. Weekly -expire binary logs older than a week. I feel like I am grabbing everything that is needed for the MyISAM databases but I am concerned about the InnoDB databases and the log files (ib_logfile0, ib_logfile1, ibdata1) they create. Should I backup these files? Nightly? Hourly? Both? Do I really need them if I am already doing the above nightly and hourly backups?

  • High PageIOLatch_SH Waits with High Drive Idle times

    - by Marty Trenouth
    We are experiencing high volume of PageIOLatch_SH waits on our database (row counts in the Billions). However it seems that our drive Idle time Percentage hovers around 50-60 percent. CPU usage is nill. The Database Tuning Advisor gives no suggestions for optimization. The query plan (actual) from the single stored procedure used on the database puts the majority of the expense on index seek (yeah I know these should be optimial) operations. Anyone have suggestions of how to increase throughput?

  • jQuery .ajax method in IE7 & IE6 not working but working fine in Firefox

    - by RyanP13
    This relates to my previous post: http://stackoverflow.com/questions/2318696/jquery-load-method-causing-page-refresh-ajax I changed my implmentation to use the .ajax method instead of .load and it works fine in Firefox but not in IE7 or IE6: $('ul#coverTabs > li > a').live('click', function(event) { // Find href of current tab var $tabValue = $(this).attr('href'); $.ajax({ type: "GET", cache: false, dataType: "html", url: $(this).attr('href'), success: function(data){ $(data).find('.benefitWrap').each(function(){ var $benefitWrap = $(this).html(); $('.benefitWrap').replaceWith($('<div class="benefitWrap">' + $benefitWrap + '</div>')); }); } }); event.preventDefault(); }); This is killing me as it has taken ages to get this far. Any ideas where i am going wrong?

  • OpenLayers, Layers: Tiled vs. single tile

    - by Chau
    Each time we add a new layer to our OpenLayers based website (data provided primarily by a GeoServer server), we discuss whether to use a single-tile or a tiled approach. Some of the parameters we evaluate are the following: Using the tiled approach we get: Slow but continuous buildup of the viewport Lots of small images Client side caching possibilities Blocking of the loading pipeline (6 requests at a time) Jerky feeling when navigating during load Using the single-tile approach we get: Smoother feeling when navigating during load Time delay before layer is loaded One large image for each layer No caching of the single tile We have a lot of data editing in the layers, thus a tile-cache might not be that efficient. Are there any best-practices when it comes to tiling? Progressing towards infinitely fast hardware and unlimited data connections, the discussion becomes irrelevant, but what configuration do you percieve as the most user-pleasing?

  • Application Context in Rails

    - by Sean McMains
    Rails comes with a handy session hash into which we can cram stuff to our heart's content. I would, however, like something like ASP's application context, which instead of sharing data only within a single session, will share it with all sessions in the same application. I'm writing a simple dashboard app, and would like to pull data every 5 minutes, rather than every 5 minutes for each session. I could, of course, store the cache update times in a database, but so far haven't needed to set up a database for this app, and would love to avoid that dependency if possible. So, is there any way to get (or simulate) this sort of thing? If there's no way to do it without a database, is there any kind of "fake" database engine that comes with Rails, runs in memory, but doesn't bother persisting data between restarts?

  • Prevent Ruby on Rails from sending the session header

    - by hurikhan77
    How do I prevent Rails from always sending the session header (Set-Cookie). This is a security problem if the application also sends the Cache-Control: public header. My application touches (but does not modify) the session hash in some/most actions. These pages display no private content so I want them to be cacheable - but Rails always sends the cookie header, no matter if the sent session hash is different from the previous or not. What I want to achieve is to only send the hash if it is different from the one received from the client. How can you do that? And probably that fix should also go into official Rails release? What do you think?

  • How do I design the file storage issue?

    - by user102533
    I am working on an application that creates video files and stores them in a folder in the C:\ drive. I speculate that there will be a large number of these files in the future and we would run out of disk space at some point of time (on our VPS). When the time comes that we have to upgrade, we either plan to use one of the Cloud providers to store files or our existing provider can add another disk (say D:\ drive). Either way, I would want to design the app now in a way that in future, moving to different locations would not be an issue and would be transparent to the end user. The code that creates these files supports 2 ways: myObj.SetOutputToDisk(<path to store>); or myObj.SetOutputToMemoryStream(ms); If we go with the Cloud architecture, I assume we might have the following combination: Cloud Files + Existing VPS or Cloud Files + Cloud Windows Server Given the unknowns at this time, how would I go about designing this?

  • Add Flickr RSS feed to Page via SimplePie

    - by Bradley Bell
    Hi all. I'm trying to add my recently uploaded flickr feed onto a site. I've followed tutorials with Simple Pie, but can't get what I desire. I need to be able dictate where each image will sit in multiple DIV's rather than just one repeated DIV. Here is a website which seems to do what I want.. wearecondiment.com It basically updates the Static URL inside each seperate DIV.. I cant find the PHP anywhere in there code. Here is the site I plan to add this feature to.. "http://www.openyourheart.org.uk" I'll make a new page and template of square DIVs where each photo will sit. The aim of it will basically be so that people can upload their own images to display in the campaign and automatically appear on the site. It would also be great if somehow the image could crop to the size of each square/rectangle. Any ideas? Cheers, Bradley

  • MVC Pattern Clarification

    - by Amutha
    Just I started learning MVC pattern,ofcourse i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there) 1 ) MVC does not support server side events ,but supports client side events.if it supports client side events,i need html page with jQuery/Javascript (view),but most of the example i absorbed is to display the information(model) in view ,i did not see any client side event handling happens in view. 2) Except ViewState and controlState,MVC supports Sessions,Application State management,Cache management. 3) When request goes to MVC engine ,the routing module routes the request that is picked up by the controller.The controller in executes the appropriate action and return the appropriate view.

  • Why can't we use a Translucent system bars with and ActionBar

    - by Waza_Be
    While updating my apps to Kitkat, I just wanted to give them a gorgeous look on KitKat using the Translucent property: Translucent system bars You can now make the system bars partially translucent with new themes, Theme.Holo.NoActionBar.TranslucentDecor and Theme.Holo.Light.NoActionBar.TranslucentDecor. By enabling translucent system bars, your layout will fill the area behind the system bars, so you must also enable [fitsSystemWindows][4] for the portion of your layout that should not be covered by the system bars. My only concern is that I would like to use an ActionBar which sounds the opposite of what Google wants (both theme have NoActionBar: Theme.Holo.NoActionBar.TranslucentDecor Theme.Holo.Light.NoActionBar.TranslucentDecor As I don't plan to use some hacks or tricks to make it work, I just wanted to know if there was some correct way to achieve this or if this would be against Google guidelines.

  • UIView Animation: Shrink

    - by Moduspwnens
    I'm looking to have my main view shrink to reveal the next view in the same way the Facebook app's views shrink when you press the top-left button. I already have it working with one of the included animations like this: [UIView beginAnimations:nil context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; [self.navigationController popToRootViewControllerAnimated:YES]; [UIView commitAnimations]; I'm fairly well-experienced with the iPhone SDK but haven't spent a lot of time with UIView animations.
