• Can I have one makefile to build a hierarchical project?

  - by saramah

  I have several hundred files in a non-flat directory structure. My Makefile lists each sourcefile, which, given the size of the project and the fact that there are multiple developers on the project, can create annoyances when we forget to put a new one in or take out the old ones. I'd like to generalize my Makefile so that make can simply build all .cpp and .h files without me having to specify all the filenames, given some generic rules for different types of files. My question: given a large number of files in a directory with lots of subfolders, how do I tell make to build them all without having to specify each and every subfolder as part of the path? And how do I make it so that I can do this with only one Makefile in the root directory?

• sizeToFit label voids align right / set minimum width of label

  - by Deco

  Here is my code I am using to make a label (which contains content of an unknown length) the correct height for the content. (lines is equal to 0) myLabel.text =[NSString stringWithFormat:@"%@", myLabelContent]; myLabel.frame = CGRectMake(myLabel.frame.origin.x, myLabel.frame.origin.y, myLabel.frame.size.width, 800); [myLabel sizeToFit]; The only problem is, it is resizing the width as well as the height. I have two labels side by side, one aligned left, one aligned right. The left aligned one works fine. However, the right aligned one becomes intended (from the right). Because of its width resize, the content always starts at the origin.x position (in effect) because the label is made to be the shortest width required. I hope that makes sense. Is there a way to override or reset the width after auto resize had solved the height problem, or set a minimum width for the label? Many Thanks in advance, Deco

• Higher speed options for executing very large (20 GB) .sql file in MySQL

  - by Jonogan

  My firm was delivered a 20+ GB .sql file in reponse to a request for data from the gov't. I don't have many options for getting the data in a different format, so I need options for how to import it in a reasonable amount of time. I'm running it on a high end server (Win 2008 64bit, MySQL 5.1) using Navicat's batch execution tool. It's been running for 14 hours and shows no signs of being near completion. Does anyone know of any higher speed options for such a transaction? Or is this what I should expect given the large file size? Thanks

• Opening Large (24 GB) File In C

  - by zacaj

  I'm trying to read in a 24 GB XML file in C, but it won't work. I'm printing out the current position using ftell() as I read it in, but once it gets to a big enough number, it goes back to a small number and starts over, never even getting 20% through the file. I assume this is a problem with the range of the variable that's used to store the position (long), which can go up to about 4,000,000,000 according to http://msdn.microsoft.com/en-us/library/s3f49ktz%28VS.80%29.aspx, while my file is 25,000,000,000 bytes in size. A long long should work, but how would I change what my compiler(Cygwin/mingw32) uses or get it to have fopen64?

• Bitmap in ImageView is cropped off the screen

  - by Computerish

  I'm working on an Android application that needs to download an image and display it inside an image view. The Bitmap is passed to the main java file and added to the image view like this: comic = (ImageView) findViewById(R.id.comic); comic.setImageBitmap(c.getImageBitmap()); This works, except that the left side of the image disappears off the screen. The ImageView is in a ScrollView and the scroll view maintains the correct size. This means that there is black space to the right in the ScrollView and the image is cut off to the left. The XML for the ImageView is this: <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" Any idea why my image is being cut off? Thanks!

• running requestAnimationFrame from within a new object

  - by JVE999

  I'm having trouble running an animation. This is inside var ob1 = function() {};. When called, it runs for a while and then I get the error Uncaught RangeError: Maximum call stack size exceeded. However, this same structure has no problems running outside of the object. /////////////// Render the scene /////////////// this.render = function (){ renderer.render(scene,camera); if(isControls == true) controls.update(clock.getDelta()); this.animate(); //console.log(true); requestAnimationFrame(this.render()); } /////////////// Update objects /////////////// this.animate = function (){ console.log("!"); }

• What is the correct way to add a subview to a new window, making it aware of its available window si

  - by favo

  Hi, This is some kind of a basic question: I am adding a new Subview to a window using: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { viewController = [[myViewController alloc] initWithNibName:@"myNib" bundle:nil]; [window addSubview:viewController.view]; This displays the view at 100% on the window, having the Clock overlaying some pixels of that view on top. Rotating makes the view aware of the clock and resizes it to begin correctly below the clock without any overlay. What is the correct way to add a subview to a new window, making it aware of its available window size?

• How to put/get INT to/from a WCHAR array ?

  - by nimo

  how can I put a INT type variable to a wchar array ? Thanks EDIT: Sorry for the short question. Yes we can cast INT to a WCHAR array using WCHAR*, but when we are retrieving back the result (WCHAR[] to INT), I just realize that we need to read size of 2 from WCHAR array since INT is 4 BYTEs which is equal to 2 WCHARs. WCHAR arData[20]; INT iVal = 0; wmemcpy((WCHAR*)&iVal, arData, (sizeof(INT))/2); Is this the safest way to retrieve back INT value from WCHAR array

• Video with transparent background on page above image background.

  - by fl00r

  Hi! I want to embed some video into my HTML page. As background I want to use big picture. And above it I want to insert loop video with (i.e.) walking man. So, can I embed video (without flash and any player controls) in page? Can I decode video with transparent background? Is there any codecs which support transparent background (alpha-channel)? Now I see this solutions: Making flash (that I don't want to use) Create gif animation (and it will be big file size and quite bad quality)

• Resizing Tab Bar Controller Views (iPhone dev)

  - by damiandawber

  Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

• Font not correctly displaying in Internet Explorer using the css property @font-face

  - by Roland

  I'm trying to render a font using the css property @font-face , in Firefox, Chrome and Opera it works fine, but within Internet Explorer is just does not want to display correctly, and reverts back to another standard font. My code looks as follows @font-face { font-family: "swatch"; src: url("../../fonts/swatch.eot"); /* IE */ src: url("../../fonts/swatch.ttf") format("truetype"); } .header_text1{ font-family: "swatch"; font-size: 78px; text-align:center; color: #ffffff; padding-top: 50px; } Am I doing something wrong here?

• Save UIView's representation to file.

  - by fish potato

  What is the easiest way to save UIView's representation to file? My solution is, UIGraphicsBeginImageContext(someView.frame.size); [someView drawRect:someView.frame]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); NSString* pathToCreate = @"sample.png"; NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; [imageData writeToFile:pathToCreate atomically:YES]; but it seems tricky, and I think there must be more efficient way to do this.

• Is there any Inheritance problem with <table> and it's elements, like <form> elements?

  - by metal-gear-solid

  Is there any Inheritance problem with <table>, tr th td tbody thead tfoot also like form elements? In IE 6+ and FF 3+ with Strict doctype. Tables also have inheritance turned off in some browsers. You may notice that in some browsers, your tables’ text will be larger, clunkier and not so pretty. This is also due to inheritance. Many browsers give tables their own style. It's mentioned here http://www.komodomedia.com/blog/2006/10/css-trickery-part-5-inheritance/ For which browsers author is talking about, it's not mentioned I tested on FF 3.6 and IE7 but unable to find is there any issue. I just wanted to be sure before adding this in my CSS reset. Do i really need this? table { font-family:inherit; font-size:inherit; font-weight:inherit; }

• [Python] How do I read binary pickle data first, then unpickle it?

  - by conradlee

  I'm unpickling a NetworkX object that's about 1GB in size on disk. Although I saved it in the binary format (using protocol 2), it is taking a very long time to unpickle this file---at least half an hour. The system I'm running on has plenty of system memory (128 GB), so that's not the bottleneck. I've read here that pickling can be sped up by first reading the entire file into memory, and then unpickling it (that particular thread refers to python 3.0, which I'm not using, but the point should still be true in python 2.6). How do I first read the binary file, and then unpickle it? I have tried: import cPickle as pickle f = open("big_networkx_graph.pickle","rb") bin_data = f.read() graph_data = pickle.load(bin_data) But this returns: TypeError: argument must have 'read' and 'readline' attributes Any ideas?

• P/Invoke or C++/CLI for wrapping a C library

  - by Ian G

  Have a moderate size (40-odd function) C API that needs to be called from a C# project. The functions logically break up to form a few classes that will be API presented to the rest of the project. Are there any objective reasons to prefer P/Invoke or C++/CLI for the interoperability underneath that API, in terms of robustness, maintainability, deployment, ...? The issues I could think of that might be, but aren't problematic are: C++/CLI will require an separate assembly, the P/Invoke classes can be in the main assembly. (We've already got multiple assemblies and there'll be the C dlls anyway so not a major issue). Performance doesn't seem differ noticeable between the two methods. Issues that I'm not sure about are: My feeling is C++/CLI will be easier to debug if there's inter-op problem, is this true? Language familiarity enough people know C# and C++ but knowledge of details of C++/CLI are rarer here. Anything else?

• How to add debug assemblies to my Silverlight 2 application?

  - by Steve Wortham

  So I know now that the debug assemblies have been intentionally left out of the Silverlight runtime to save space. For that reason I get good detailed error messages on my local machine that has the Silverlight SDK on it, but I don't on a computer with the runtime only. I get the ubiquitous, "Debugging resource strings are unavailable." Unfortunately my requirements are a bit unique. I need to include the debug assembly (not sure which one yet) that will give me details of a regular expression error. And so essentially I want to include the dll in the xap if I can. The problem is that I can't seem to do this. I've tried adding the debug dll's as references and setting them to "copy local." And I've tried adding them into the project as content. But in fact, with either method the xap hardly grows in size and the error message doesn't change. Any ideas?

• Symfony2 Setting a default choice field selection

  - by Mat

  I am creating a form in the following manner: $form = $this->createFormBuilder($breed) ->add('species', 'entity', array( 'class' => 'BFPEduBundle:Item', 'property' => 'name', 'query_builder' => function(ItemRepository $er){ return $er->createQueryBuilder('i') ->where("i.type = 'species'") ->orderBy('i.name', 'ASC'); })) ->add('breed', 'text', array('required'=>true)) ->add('size', 'textarea', array('required' => false)) ->getForm() How can I set a default value for the species listbox? Thank you for your response, I apologise, I think I should rephrase my question. Once I have a value that I retrieve from the model, how do I set that value as SELECTED="yes" for the corresponding value in the species choice list? So, that select option output from the TWIG view would appear like so: <option value="174" selected="yes">Dog</option>

• When to use the Flyweight Pattern

  - by elmt

  So I've just gotten on the boost train and was checking out the flyweight pattern and was interested in implementing it in my project. Obviously, it doesn't make sense to use it on any class that has only has one instance of it. However, say I have 5 instances of an class. Should I be using the flyweight pattern or should it be only used for a class that has at least N instances. I realize that many factors will influence this answer (how many fields there are, the size of the fields, etc.).

• Performance problem Loading Dataset inside a virtual.

  - by ShaneH

  Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

• Best way to store chat messages and files

  - by Stnaire

  I would like to know what do you think about storing chat messages in a database? I need to be able to bind other stuff to them (like files, or contacts) and using a database is the best way I see for now. The same question comes for files, because they can be bound to chat messages, I have to store them in the database too.. With thousands of messages and files I wonder about performance drops and database size. What do you think considering I'm using PHP with MySQL/Doctrine?

• What is the preferred way to associate css styles with GWT widgets (using UiBinder)?

  - by smallbec

  From the GWT page (http://code.google.com/webtoolkit/doc/latest/DevGuideUiCss.html#cssfiles), it mentions 2 ways (for modern application): Using a CssResource contained within a ClientBundle. Using an inline element in a UiBinder template. Modern GWT applications typically use a combination of CssResource and UiBinder. So my question is, when should I use a css file and create a CssResource for it, and when should I define styles directly in the ui.xml file using <ui:style>? Are there any performance implication (i.e. resource size to download on the client) with either of these ways?
