  • Choosing a non microsoft language for web development?

    - by Luke Lowrey
    I am resonably experienced with asp.net and would like to learn a new language with a focus on web development. Licensing and hosting costs are why I would like to use something not reliant on microsoft so something based on open source technologies is a plus. I have had a tiny bit of experience with php and did not like it but I guess I could be convinced otherwise. Basically I'd like to know peoples opinion on the the best language for future web development with regards to longivity, resources, frameworks, hosting etc.

  • Dotted Border turns to solid if object is animated with jQuery.

    - by Serg Chernata
    I have a simple setup: an image and then a paragraph with a bit of info that is hidden and then slides up over the image on mouse hover. If I try to apply a border-top that is dashed or dotted onto the paragraph it simply turns into a solid line. Is this a known issue with a fix? I even tried adding the dotted border through jQuery and it still comes out as a solid line. <div class="wrap"> <img src="images/fillertxt.jpg" alt="image" /> <img src="images/filler.jpg" class="front" alt="image" /> <p class="info"> This is a short description with a bit of text. </p> </div> .wrap .info { width:204px; height:50px; background:url(images/infobg.jpg) repeat-x #8d9c0c; color:#f7f5ef; padding:3px; position:absolute; top:142px; left:0; border-top:3px dotted #8d9c0c; } $(document).ready(function(){ $("p.info").css("border-top","3px dotted #8d9c0c"); $(function(){ bindTypeOne(); $("input[type=radio]").click(function(){ if ($(this).attr("rel") == "type1"){ bindTypeOne(); } else if ($(this).attr("rel") == "type2"){ bindTypeTwo(); } }); }); function bindTypeOne() { $("div.wrap").hover(function(){ $(this).children("p.info").stop(); $(this).children(".front").stop().animate({"top":"141px"}, 400); },function(){ $(this).children("p.info").stop(); $(this).children(".front").stop().animate({"top":"0"}, 700); }); }; function bindTypeTwo() { $("div.wrap").hover(function(){ $(this).children(".front").stop(); $(this).children("p.info").stop().animate({"top":"80px","border-top":"3px dotted #8d9c0c"}, 400); },function(){ $(this).children(".front").stop(); $(this).children("p.info").stop().animate({"top":"142px"}, 700); }); }; });

  • How are integers casted to bytes in Java?

    - by helixed
    I know Java doesn't allow unsigned types, so I was wondering how it casts an integer to a byte. Say I have an integer a with a value of 255 and I cast the integer to a byte. Is the value represented in the byte 11111111? In other words, is the value treated more as a signed 8 bit integer, or does it just directly copy the last 8 bits of the integer? Thanks, helixed

  • LINQ to SQL: To Attach or Not To Attach

    - by bradhe
    So I'm have a really hard time figuring out when I should be attaching to an object and when I shouldn't be attaching to an object. First thing's first, here is a small diagram of my (very simplified) object model. Edit: Okay, apparently I'm not allowed to post images...here you go: http://i.imgur.com/2ROFI.png In my DAL I create a new DataContext every time I do a data-related operation. Say, for instance, I want to save a new user. In my business layer I create a new user. var user = new User(); user.FirstName = "Bob"; user.LastName = "Smith"; user.Username = "bob.smith"; user.Password = StringUtilities.EncodePassword("MyPassword123"); user.Organization = someOrganization; // Assume that someOrganization was loaded and it's data context has been garbage collected. Now I want to go save this user. var userRepository = new RepositoryFactory.GetRepository<UserRepository>(); userRepository.Save(user); Neato! Here is my save logic: public void Save(User user) { if (!DataContext.Users.Contains(user)) { user.Id = Guid.NewGuid(); user.CreatedDate = DateTime.Now; user.Disabled = false; //DataContext.Organizations.Attach(user.Organization); DataContext.Users.InsertOnSubmit(user); } else { DataContext.Users.Attach(user); } DataContext.SubmitChanges(); // Finished here as well. user.Detach(); } So, here we are. You'll notice that I comment out the bit where the DataContext attachs to the organization. If I attach to the organization I get the following exception: NotSupportedException: An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported. Hmm, that doesn't work. Let me try it without attaching (i.e. comment out that line about attaching to the organization). DuplicateKeyException: Cannot add an entity with a key that is already in use. WHAAAAT? I can only assume this is trying to insert a new organization which is obviously false. So, what's the deal guys? What should I do? What is the proper approach? It seems like L2S makes this quite a bit harder than it should be...

  • PHP queue jobs in centOS

    - by Soe Naung Win
    I wrote a PHP shell script which include queuing jobs in centOS with 'at' command. The queue jobs may vary in time and contents which means the system need to keep quite a large number of jobs. The application logic will also be a bit difficult to setup with cronjob. Is there a limit in number of queue jobs in centOS or is there any alternative way of queuing jobs?

  • Lazy load pages in UIScrollView

    - by jean
    I have a UIScrollView that contains large images and am using paging to scroll between images. In order to save memory, I am loading only one image before and after the currently visible one and loading/releasing new images after a scroll has completed. The problem occurs when one scrolls quickly and scrollViewDidEndDecelerating is not called. How can I detect continuous scrolling? I could check item location on every scrollViewDidScroll but this seems a bit heavy...

  • C# Putting the required DLLs somewhere other than the root of the output

    - by aip.cd.aish
    I am using EmguCV for a project and when our program runs it needs some dlls like "cxcore.dll" etc. (or it throws runtime exceptions). At the moment, I put the files in the root of the output folder (selected "Copy Always" in the file's properties in Visual Studio). However it looks a bit messy, to have about 10 different dlls just there. Is there someway where I can move it to a subfolder in the output folder and it'll still find it.

  • In WPF, What is the best way to create toolbar buttons so that the images are properly scaled?

    - by T.R.
    Specifically, I'm looking to use the 16*16 32-bit png images included with the VS2008ImageLibrary. I've tried manually setting the Height and Width attributes of the image, adjusting margins and padding, adjusting Stretch and RenderOptions. My attempts to create toolbar buttons have all led to either Improper Scaling (blurry icons), the bottom row of pixels on the icon being truncated, or the toolbar button being improperly sized - not to mention the disappearing icons already mentioned Here. Has anyone found the best way to make standard, VisualStudio/WinForms-style toolbar buttons that display properly in WPF?

  • Use of * in Objective C Syntax

    - by user263097
    I'm struggling a bit with some objective c syntax. Can someone please elaborate on the usage of * in the following instance method. - (IBAction)sliderChanged:(id)sender{ UISlider *slider = (UISlider *)sender; } I realize that we are creating a variable typed as UISlider and then setting it to sender once it is cast as a UISlider. However, I don't understand what the * are for and why UISlider slider = (UISlider)sender; won't work.

  • Microsoft Robotics Studio with Wine ? Is it possible ?

    - by Arkapravo
    I am using Ubuntu 9.10 and I am a bit of a robotics enthusiast. I have used KiKS (in MATLAB for simulating Khepera robots), MobotSim (in Windows, simulates a point like robot using a BASIC editor) and Player Stage/Gazebo (with C/C++ on Ubuntu Linux). My question, can MS Robotics Studio be installed in Ubuntu Linux using Wine (I am using 1.1.31) ? Has anyone done it ? Thanks for your reply !

  • Return ArrayList from .net web service to android application using kSoap

    - by benjamin schultz
    My web service is returning quite a bit of data, so i'm storing it in an arraylist and returning that to my application. I don't know whether or not this is the preferred method or not. When the arraylist is returned and displayed in my application, it also displays the arraylists "anyType" section. I'm new to this whole process so i'm sure i'm missing something somewhere or going about this incorrectly. Can anyone point me in the right direction please?

  • Fluent interface and task based applications

    - by Mmarquee
    We have a number of applications that are now looking tired and a bit drab. Looking at the MS style fluent interface looks nice but seems (to me) to be more document based rather than task based. Is there a nice 'modern' ui style that lends itself to task based applications?

  • App.Config or XAML

    - by Florian Doyon
    Hi ladies(?) and gents, I am currently evaluating my options for a rewrite of the projects I'm working on and I am a bit miffed by the stringly-typed nature of our app.config files. I'd like to move to a more structured approach, so I have two options: Use custom SectionHandlers in the app.config Scrap app.config and use XAML instead. I'd like to get your opinions and horror stories on this, what are the pros and cons of using XAML for this? Cheers, Florian

  • Handling empty UITableView in UITableViewController

    - by Travis
    I have a UITableViewController that is populated with some data. If the data comes back empty, obviously the table is empty. What is the appropriate method to use to handle this case and put up something like a UILabel with "No Data Available". I have been using - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section but it's proven a bit cumbersome and I'm not longer confident it's the best place to do this.

  • How to make ARGB transparency using bitwise operators.

    - by Smejda
    I need to make transparency, having 2 pixels: pixel1: {A, R, G, B} - foreground pixel pixel2: {A, R, G, B} - background pixel A,R,G,B are Byte values each color is represented by byte value now I'm calculating transparency as: newR = pixel2_R * alpha / 255 + pixel1_R * (255 - alpha) / 255 newG = pixel2_G * alpha / 255 + pixel1_G * (255 - alpha) / 255 newB = pixel2_B * alpha / 255 + pixel1_B * (255 - alpha) / 255 but it is too slow I need to do it with bitwise operators (AND,OR,XOR, NEGATION, BIT MOVE)

  • Map /dev/bus/usb node to /sys node on Linux

    - by Cody Brocious
    I'm using libusb to find and access a USB device, but once I get the information I need from there, I need to map it to a /sys node. This could be to the actual USB bus it's on, the /sys/bus/usb-serial node (which is where I'm going to get eventually), or effectively anywhere else since I can walk the tree from there. I can get to a /dev/bus/usb node easily enough, but I'm a bit lost from there. What would be the best route to perform this mapping?

  • Executing Custom Actions immediately in WIX

    - by jbloomer
    Is there any way to execute a custom action in WIX as soon as the first dialog (welcome) appears? The requirement is to check prerequisites, and some of those require a custom action. The custom action could be executed as we click to the next dialog, but then the standard WIX prereqs are determined apart from our custom prereq. (The custom action we need is to check that IIS 6 Metabase Compatibility is turned on and a registry search does not work on x64 machines with a 32-bit installer)

    Good Morning. I've been reading Joel Spolsky's (joelonsoftware) articles and they are full of good information and tips. He's a good writer and well worth reading. I am wondering what other good blogs/articles/books are out there written by similar people - really after leaders/managers/biz owners who are/were developers. Hope that makes a bit of sense ;-)
