• Is it necessary to understand what's happening at the hardware level to be a good programmer?

  - by bev

  I'm a self-taught programmer, just in case this question is answered in CS 101. I've learned and used lots of languages, mostly for my own personal use, but occasionally for professional stuff. It seems that I'm always running into the same wall when I run into trouble programming. For example, I just asked a question on another forum about how to handle a pointer-to-array that was returned by a function. Initially I'm thinking that I simply don't know the proper technique that the designers of C++ set up to handle the situation. But from the answers and discussions that follow I see that I don't really get what happens when something is 'returned'. How deep a level of understanding of the programming process must a good programmer achieve?

• SQL binary value to PHP variable leading zeros

  - by Agony

  Using sql query to pull data from a mssql database results in a value that still has leading zeros. The data in database is stored as binary(13) - so it will pull all 13 digits. However the value is a text, so any leading zeros will generally show up as '?' in a form on the site - and in return will update wrong data to the database later. So what i need is to only select/display the text itself, not all 13 bytes. using: SELECT CONVERT(char,uilock_pw) AS uipwd FROM tbl_UserAccount or SELECT uilock_pw FROM tbl_UserAccount still adds the leading zeros to the char array. Example in database: 0x71776531323300000000000000 Would show up as: qwe123??????? But should be: qwe123 Im not even sure what character those ? represent. Using Echo results in a normal qwe123 - but not in a form.

• Whether to use -pedantic flag in g++ or not?

  - by user803563

  I'm learning C++ and I'm using g++ on Linux for practicing. 1) I want to know if people working as programmers use g++ -pedantic flag and also it's importance in real world. 2) What about other compilers, do they also allow this? Has this become some de-facto standard? I'm interested because I'm reading C++ Primer where the author points that its illegal to use non-const expression as dimension in array definition and g++ by default allows it. And there might be other things I'm unaware of.

• What is the most cross-browser/system compatible option for 3d graphics on a web page?

  - by LachlanB

  I would like to develop a bit of functionality for a web site that involves a bit of 3D - the user can move around objects, rotate them and texture them. So far I've looked into: WebGL (in particular three.js) and it looks great, but it's not supported in IE nor IOS. IOS supports the <canvas> tag, but only 2d. It looks like three.js has an unsupported hack to make a 3d thing use the 2d canvas instead without textures, but this looks like a hack. I also considered resorting to Flash which works on most browsers, but that won't work on IOS. What's my best option for doing 3d web graphics on the vast array of browsers and interfaces? At the moment I'm thinking WebGL for web (and ask people to use chrome or firefox, and take the hit on IE) and then maybe write a native app for IOS, but I am not sure if there are better alternatives available that I don't know of.

• Using T[1] instead of T for functions overloaded for T(&)[N]

  - by Abyx

  The asio::buffer function has (void*, size_t) and (PodType(&)[N]) overloads. I didn't want to write ugly C-style (&x, sizeof(x)) code, so I wrote this: SomePacket packet[1]; // SomePacket is POD read(socket, asio::buffer(packet)); foo = packet->foo; But that packet-> looks kinda weird - the packet is an array after all. (And packet[0]. doesn't look better.) Now, I think if it was a good idea to write such code. Maybe I should stick to unsafe C-style code with void* and sizeof? Upd: here is another example, for writing a packet: SomePacket packet[1]; // SomePacket is POD packet->id = SomePacket::ID; packet->foo = foo; write(socket, asio::buffer(packet));

• Apache 2.4 PHP 5.4 MySQL enabled but not found? [migrated]

  - by jurchiks

  Just tried setting up the latest Apache (2.4.1 x86 VC10 from apachelounge) and PHP (5.4 VC9 TS X86, with the php5apache2_4.dll) on my PC and ran into this weird problem; in my php.ini I have enabled all of the following: extension=php_mysql.dll extension=php_mysqli.dll extension=php_pdo_mysql.dll but when I try to print the available PDO's using this: print_r(PDO::getAvailableDrivers()); It gives me an empty array. PhpMyAdmin and MantisBT also refuse to work, saying that the mysql extension is missing. phpinfo() gives this: PDO PDO support enabled PDO drivers no value and when searching for mysql, only the mysqlnd section pops up... The DLLs are there in the D:/php/ext folder and no errors pop up when starting up Apache, as well as no errors in the Windows Event Log, and PHP itself has no error log anyway. What could possibly be the problem with this? Before this I had Apache 2.2.22 from apachelounge and PHP 5.3.9 and I had no problems. Now nothing works...

• What are the pros and cons of Coffeescript?

  - by Philip

  Of course one big pro is the amount of syntactic sugar leading to shorter code in a lot of cases. On http://jashkenas.github.com/coffee-script/ there are impressive examples. On the other hand I have doubts that these examples represent code of complex real world applications. In my code for instance I never add functions to bare objects but rather to their prototypes. Moreover the prototype feature is hidden from the user, suggesting classical OOP rather than idiomatic Javascript. The array comprehension example would look in my code probably like this: cubes = $.map(list, math.cube); // which is 8 characters less using jQuery...

• Using replacement to get possible outcomes to then search through HUGE amount of data

  - by Samuel Cambridge

  I have a database table holding 40 million records (table A). Each record has a string a user can search for. I also have a table with a list of character replacements (table B) i.e. i = Y, I = 1 etc. I need to be able to take the string a user is searching for, iterate through each letter and create an array of every possible outcome (the users string, then each outcome with alternative letters used). I need to check for alternatives on both lower and uppercase letters in the word A search string can be no longer than 10 characters long. I'm using PHP and a MySQL database. Does anyone have any thoughts / articles / guidance on doing this in an efficient way?

• Returning status code where one of many errors could have occured

  - by yttriuszzerbus

  I'm developing a PHP login component which includes functions to manipulate the User object, such as $User->changePassword(string $old, string $new) What I need some advice with is how to return a status, as the function can either succeed (no further information needs to be given) or fail (and the calling code needs to know why, for example incorrect password, database problem etc.) I've come up with the following ideas: Unix-style: return 0 on success, another code on failure. This doesn't seem particularly common in PHP and the language's type-coercion messes with this (a function returning FALSE on success?) This seems to be the best I can think of. Throw an exception on error. PHP's exception support is limited, and this will make life harder for anybody trying to use the functions. Return an array, containing a boolean for "success" or not, and a string or an int for "failure status" if applicable. None of these seem particularly appealing, does anyone have any advice or better ideas?

• How do I swap two objects in C# (specifically Mono) without triggering GC?

  - by TenFour04

  I have two array lists. that I want to swap each frame. My question is, does the variable 'temp' need to be a member variable to avoid triggering GC, assuming this method is called on dozens of objects each frame? I'm not creating a new object, just a new reference to an object. public void LateUpdate(){ ArrayList<int> temp = previousFrameCollisions; previousFrameCollisions = currentFrameCollisions; currentFrameCollisions = temp; currentFrameCollisions.clear(); } I've been told there's no reason to make a primitive into a member variable just to avoid GC, so my best guess is that this also applies to object references.

• Random List of numbers in C

  - by Ant

  I have just started a C programming course and so far have only done the basics like printf, read a little on variables etc on the course book. The teacher has tasked us with writing a program that will take a value entered by the user, this will be the number of students in the class (25 at the moment but can be variable). It will then list the number of students randomly and place them in 3 columns. The purpose is to sort students into groups of 3 randomly, then display on the screen in columns. Now my question is not for the code that defeats the object of me attempting the exercise, but how to structure it. I can see that using an array can be used to display the list, but really after some pointers on how best to approach the problem in blocks, then I can attempt to program each block.

• redimension multidimensional arrays in Excel VBA [migrated]

  - by user147178

  Take a look at the following code. What my problem is is that I can't figure out how to redimension the n integer and the b integer. What I'm doing is the array sent1 is already working and it is populated with about 4 sentences. I need to go through each sentence and work on it but I'm having trouble. dim sent1() dim sent2() dim n as integer, b as integer, x as integer dim temp_sent as string b = 0 For n = 1 to ubound(sent1) temp_sent = sent1(n) for x = 1 to len(temp_sent1) code if a then b = b + 1 THIS IS THE PART OF THE CODE THAT IS NOT WORKING redim preserve sent2(1 to ubound(sent1), b) sent2(n,b) = [code] next next

• Generate Unique Abstract Backgrounds with Ablaze

  - by Jason Fitzpatrick

  If you want custom and unique backgrounds without having to code your own image-generating engine, Ablaze makes it simple (and fun) to create abstract images. You can customize a wide array of options in Ablaze including the base shape (ring, horizontal line, or random), number of particles, distance each particle travels, and the speed (if you increase the speed range you get more distinct lines and if you decrease it you get smoother smokier shapes). You can also seed the design with a color palette pulled from any image you provide (the sample above was seeded with a Wonder Woman comic panel). Tweak and reset the pattern generation as much as you want; when you create an abstract image worthy of your desktop just click the save button to grab a copy of it in PNG format.

• How to remove items from an arraylist without shrinking the list [migrated]

  - by user73710

  I have a case where I am using the ArrayList to keep a list of items that are keyed by their position in the list. Other objects reference the ArrayList items by their position. If I delete one of the items from the list, I don't want the list to shrink because that would invalidate all other references to items in the list (e.g. item 2 is now in position 1). My solution to the shrinking array list problem is to null the position in the arraylist so that the list will not shrink. I am curious whether this will free the memory formerly held by the item at that position. If there is a better way to accomplish this requirement, I would like to know about it.

• Encryption is hard: AES encryption to Hex

  - by Rob Cameron

  So, I've got an app at work that encrypts a string using ColdFusion. ColdFusion's bulit-in encryption helpers make it pretty simple: encrypt('string_to_encrypt','key','AES','HEX') What I'm trying to do is use Ruby to create the same encrypted string as this ColdFusion script is creating. Unfortunately encryption is the most confusing computer science subject known to man. I found a couple helper methods that use the openssl library and give you a really simple encryption/decryption method. Here's the resulting string: "\370\354D\020\357A\227\377\261G\333\314\204\361\277\250" Which looks unicode-ish to me. I've tried several libraries to convert this to hex but they all say it contains invalid characters. Trying to unpack it results in this: string = "\370\354D\020\357A\227\377\261G\333\314\204\361\277\250" string.unpack('U') ArgumentError: malformed UTF-8 character from (irb):19:in `unpack' from (irb):19 At the end of the day it's supposed to look like this (the output of the ColdFusion encrypt method): F8E91A689565ED24541D2A0109F201EF Of course that's assuming that all the padding, initialization vectors, salts, cypher types and a million other possible differences all line up. Here's the simple script I'm using to encrypt/decrypt: def aes(m,k,t) (aes = OpenSSL::Cipher::Cipher.new('aes-256-cbc').send(m)).key = Digest::SHA256.digest(k) aes.update(t) << aes.final end def encrypt(key, text) aes(:encrypt, key, text) end def decrypt(key, text) aes(:decrypt, key, text) end Any help? Maybe just a simple option I can pass to OpenSSL::Cipher::Cipher that will tell it to hex-encode the final string?

• OpenCV Mat creation memory leak

• LoaderLock was detected, and turning off the warning does not help

  - by Scott M.

  I am trying to write an application that takes in sound from the default audio recording device on a computer. When running any code that accesses DirectX from my managed code i get this error: DLL 'C:\Windows\assembly\GAC\Microsoft.DirectX.DirectSound\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.DirectSound.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang. DevicesCollection coll = new DevicesCollection(); and Device d = new Device(DSoundHelper.DefaultCaptureDevice); and Capture c = new Capture(DSoundHelper.DefaultCaptureDevice); all cause the LoaderLock MDA to pop up and tell me there is a problem. I have scoured the internet (stackoverflow included) for solutions to this problem, but most people just say to turn off the warning, which does not work. When I turn off the warning, a generic ApplicationException is thrown, which is even less useful. I have seen the answers to this question as well, which didn't help because he said to remove the code that is causing the error. Others have said "fix your code." My questions are: how can I call any (preferably managed) DirectX code from C# without getting this error?

• Creating a session scoped bean in Google App Engine using Spring 2.5

  - by zfranciscus

  Hi, I am trying to create a session bean in spring mvc. I am having the following error message when I run my google app engine server in my local box: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'siteController' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Cannot resolve reference to bean 'oAuth' while setting bean property 'oAuth'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'oAuth' defined in BeanDefinition defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: **Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.** This is my spring mvc configuration: <bean name="oAuth" class="org.locate.server.FoursquareMgr" scope="session"> <aop:scoped-proxy/> </bean> <bean name="siteController" class="org.locate.server.SiteController" > <property name="oAuth" ref="oAuth"></property> </bean> I have enabled session in my google app engine appengine-web.xml file <sessions-enabled>true</sessions-enabled> I have included CGLIB2: cglib-2.1_3.jar and cglib-nodep-2.1_3.jar in my eclipse project build path. Has any one encountered this problem before ?

• Subclassing UINavigationBar ... how do I use it in UINavigationController?

  - by funkadelic

  Hi, I wanted to subclass UINavigationBar (to set a custom background image & text color) and use that for all the navigation bars in my app. Looking at the API docs for UINavigationController, it looks like navigationBar is read-only: @property(nonatomic, readonly) UINavigationBar *navigationBar Is there a way to actually use a custom UINavigationBar in my UIViewControllers? I know that other apps have done custom navigation bars, like flickr: Here is my UINavigationBar subclass: #import <UIKit/UIKit.h> @interface MyNavigationBar : UINavigationBar <UINavigationBarDelegate> { } @end the implementation #import "MyNavigationBar.h" @implementation MyNavigationBar - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // override the standard background with our own custom one UIImage *image = [[UIImage imageNamed:@"navigation_bar_bgd.png"] retain]; [image drawInRect:rect]; [image release]; } #pragma mark - #pragma mark UINavigationDelegate Methods - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ // use the title of the passed in view controller NSString *title = [viewController title]; // create our own UILabel with custom color, text, etc UILabel *titleView = [[UILabel alloc] init]; [titleView setFont:[UIFont boldSystemFontOfSize:18]]; [titleView setTextColor:[UIColor blackColor]]; titleView.text = title; titleView.backgroundColor = [UIColor clearColor]; [titleView sizeToFit]; viewController.navigationItem.titleView = titleView; [titleView release]; viewController.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.1 green:0.2 blue:0.3 alpha:0.8]; } - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ } - (void)dealloc { [super dealloc]; } @end I know that I can use a category to change the background image, but i still want to be able to set the text color of the navigation bar title @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"navigation_bar_bgd.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end any suggestions or other solutions? I basically want to create a light background and dark text like Flickr's app navigation bars

• Mixing Objective-C and C++

  - by helixed

  Hello, I'm trying to mix together some Objective-C code with C++. I've always heard it was possible, but I've never actually tried it before. When I try to compile the code, I get a bunch of errors. Here's a simple example I've created which illustrates my problems: AView.h #import <Cocoa/Cocoa.h> #include "B.h" @interface AView : NSView { B *b; } -(void) setB: (B *) theB; @end AView.m #import "AView.h" @implementation AView - (id)initWithFrame:(NSRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code here. } return self; } - (void)drawRect:(NSRect)dirtyRect { // Drawing code here. } -(void) setB: (B *) theB { b = theB; } @end B.h #include <iostream> class B { B() { std::cout << "Hello from C++"; } }; Here's the list of errors I get when I try to compile this: /Users/helixed/Desktop/Example/B.h:1:0 /Users/helixed/Desktop/Example/B.h:1:20: error: iostream: No such file or directory /Users/helixed/Desktop/Example/B.h:3:0 /Users/helixed/Desktop/Example/B.h:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'B' /Users/helixed/Desktop/Example/AView.h:5:0 /Users/helixed/Desktop/Example/AView.h:5: error: expected specifier-qualifier-list before 'B' /Users/helixed/Desktop/Example/AView.h:8:0 /Users/helixed/Desktop/Example/AView.h:8: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:26:0 /Users/helixed/Desktop/Example/AView.m:26: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:27:0 /Users/helixed/Desktop/Example/AView.m:27: error: 'b' undeclared (first use in this function) All I'm doing to compile this right now is using the default compiler built into Xcode. I didn't edit the Cocoa Application template in any way other than adding the two files I created and chaing the NSView to AView in the xib file. Could somebody please tell me what I'm doing wrong? Thanks, helixed

• How to populate Java (web) application with initial data using Spring/JPA/Hibernate

  - by Tuukka Mustonen

  I want to setup my database with initial data programmatically. I want to populate my database for development runs, not for testing runs (it's easy). The product is built on top of Spring and JPA/Hibernate. Developer checks out the project Developer runs command/script to setup database with initial data Developer starts application (server) and begins developing/testing then: Developer runs command/script to flush the database and set it up with new initial data because database structures or the initial data bundle were changed What I want is to setup my environment by required parts in order to call my DAOs and insert new objects into database. I do not want to create initial data sets in raw SQL, XML, take dumps of database or whatever. I want to programmatically create objects and persist them in database as I would in normal application logic. One way to accomplish this would be to start up my application normally and run a special servlet that does the initialization. But is that really the way to go? I would love to execute the initial data setup as Maven task and I don't know how to do that if I take the servlet approach. There is somewhat similar question. I took a quick glance at the suggested DBUnit and Unitils. But they seem to be heavily focused in setting up testing environments, which is not what I want here. DBUnit does initial data population, but only using xml/csv fixtures, which is not what I'm after here. Then, Maven has SQL plugin, but I don't want to handle raw SQL. Maven also has Hibernate plugin, but it seems to help only in Hibernate configuration and table schema creation (not in populating db with data). How to do this?
