• Subclassing UIScrollView for drawing w/o views

  - by David Dunham

  I'm contemplating subclassing UIScrollView (the way UITextView does) to draw a fairly large amount of text (formatted in ways that NSTextView can't). So far the view won't actually scroll. I'm setting contentSize, and when I drag, I see the scroll indicator. But nothing changes (and I don't get a drawRect: message). An alternate approach is to use a child view, and I've done this. The view can be over 5000 pixels high, however, and I'm a bit concerned about performance on an actual device. (The other approach, be like UITableView, would be a huge pain -- I'm "porting" Mac Cocoa code, and a collection of views would be a huge architecture change.) I've done some searching, but haven't found anyone who is using UIScrollView to do the drawing. Has anyone done this and know of any pitfalls?

• Game Programming - GUIs

  - by Spencer

  I've been coding for a while now and would like to start looking into programming games. I know the industry's standard language is C++, for 3D graphics the main choice is between Direct 3D and OpenGL, but what is the most widely used GUI framework? I'm currently on a Mac so if native Windows API is the answer, then what is the cross platform choice? To be clear, I'm not looking for people's favourites but simply what the common or standard game industry's choice is so that I can learn and familiarize myself with it. Thanks, Spencer

• Attachment_fu error

  - by cswebgrl

  Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

• How can I install ruby on rails with rvm?

  - by yeahthatguyrightthere

  I've been searching around on how to install it through the terminal on my mac. I'm using snow leopard. When I use the command: rvm install 1.9.3 I've also followed the other procedures that led me up to this to install, right now the current version is 1.8.3 Error running './configure --prefix="/Users/jose/.rvm/usr" ', please read /Users/jose/.rvm/log/ruby-1.9.3-p125/yaml/configure.log Then it mentions something about xcode and autoreconf was not found in the PATH. Error running 'patch -F 25 -p1 -N -f <"/Users/jose/.rvm/patches/ruby/1.9.3/p125/xcode-debugopt-fix-e34840.diff"',please read /Users/jose/.rvm/log/ruby-1.9.3-p125/patch.apply.xcode-debugopt-fix-r34840.log rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH I been trying for awhile now, and found out i need to have Xcode for snow leopard which I cannot find. So my last option will be to upgrade to lion but I don't know about upgrading. Kind of scared to upgrade and everything becomes buggy.

• Parse error: syntax error, unexpected T_PUBLIC in ..... ?

  - by tonsils

  Hi, I am new to php and trying out this tutorial at : http://css-tricks.com/php-for-beginners-building-your-first-simple-cms/ Unfortunately I am getting the following error and can't seem to track down the reason: Parse error: syntax error, unexpected T_PUBLIC in ../simpleCMS.php on line 56 My code for simpleCMS.php is as is in the tutorial link above. FYI, my line 56 is the following line of code in simpleCMS.php public function display_admin() { Above this line is public function display_public() Can anyone possibly see what I could be doing wrong and again, my code is the same code from the tutorial website and have downloaded the files that came with it? Hoping someone can point me in the right direction. Furthermore, I am using Mac OS X MAMP to run my Apache/MySQL Server locally. My other question is, when I using the following command: mysql_connect($this->host,$this->username,$this->password) is my hostname 'localhost' alone or do I also have to include port alongside the localhost? Thanks again.

• Why is there no music streaming API service?

  - by Chad Johnson

  Apple has decided to kill lala.com. I loved that site. Now, everyone has to go back to paying $0.89+ for songs from Amazon, iTunes, etc. Lame. Rhapsody would be great, except there are no clients for Mac or Linux. They do have a web interface, buy it is nothing compared to lala's web 2.0y interface. What I just don't understand is, why is there no music API streaming service out there? Basically, developers could hook the service into any desktop or web app, and then users of the app could pay $x a month (like with Rhapsody) and play any amount of music, so long as their subscription is active. Why not? Lala streamed music to web browsers, so surely it could be as secure as lala is (was), preventing music theft.

• XAMPP is caching .html files running as PHP

  - by Lee

  I have XAMPP (latest version) installed on my Mac OS 10.6.3 I've added the following to .htaccess because I want .html to be interpreted as PHP. AddType application/x-httpd-php .php .html The problem is that the default XAMPP config seems to be caching .html files as static... so even though the PHP statements inside are being called (for example, 'echo time()' in index.html displays the dynamic output)... the actual file is being cached. When I make changes to a .html file, I've having to restart Apache for it to load the newest changes. Looking at httpd.conf, it looks like it's loading the following cache mods.. LoadModule file_cache_module modules/mod_file_cache.so LoadModule cache_module modules/mod_cache.so LoadModule disk_cache_module modules/mod_disk_cache.so LoadModule mem_cache_module modules/mod_mem_cache.so Any idea how to implement a system whereby it checks the timestamp of the file, before loading it from cache? Thanks!

• What is the RSA SecurID packet format?

  - by bmatthews68

  I am testing a client application that authenticates using RSA SecurID hardware tokens. The authentication is failing and I am not finding any useful information in the log files. I am using Authentication Manager 8.0 and the Java SDK. I have a traffic capture which I would like to analyze with Wireshark to and from port 5500 on the authentication agent. But I can't find the packet format searching the internet or on the the RSA SecurCare knowledge base. Can anybody direct me to the packet format? Here is an extract from the rsa_api_debug.log file which dumps the UDP payload of the request and the response: [2013-11-06 15:11:08,602] main - b.a():? - Sending 508 bytes to 192.168.10.121; contents: 5c 5 0 3 3 5 0 0 2 0 0 0 0 0 1 ea 71 ee 50 6e 45 83 95 8 39 4 72 e 55 cf cc 62 6d d5 a4 10 79 89 13 d5 23 6a c1 ab 33 8 c3 a1 91 92 93 4f 1e 4 8d 2a 22 2c d0 c3 7 fc 96 5f ba bf 0 80 60 60 9d 1d 9c b9 f3 58 4b 43 18 5f e0 6d 5e f5 f4 5d df bf 41 b9 9 ae 46 a0 a9 66 2d c7 6 f6 d7 66 f1 4 f8 ad 8a 9f 4d 7e e5 9c 45 67 16 15 33 70 f0 1 d5 c0 38 39 f5 fd 5e 15 4f e3 fe ea 70 fa 30 c9 e0 18 ab 64 a9 fe 2c 89 78 a2 96 b6 76 3e 2e a2 ae 2e e0 69 80 8d 51 9 56 80 f4 1a 73 9a 70 f3 e7 c1 49 49 c3 41 3 c6 ce 3e a8 68 71 3f 2 b2 9b 27 8e 63 ce 59 38 64 d1 75 b7 b7 1f 62 eb 4d 1d de c7 21 e0 67 85 b e6 c3 80 0 60 54 47 e ef 3 f9 33 7b 78 e2 3e db e4 8e 76 73 45 3 38 34 1e dd 43 3e 72 a7 37 72 5 34 8e f4 ba 9d 71 6c e 45 49 fa 92 a f6 b bf 5 b 4f dc bd 19 0 7e d2 ef 94 d 3b 78 17 37 d9 ae 19 3a 7e 46 7d ea e4 3a 8c e1 e5 9 50 a2 eb df f2 57 97 bc f2 c3 a7 6f 19 7f 2c 1a 3f 94 25 19 4b b2 37 ed ce 97 f ae f ec c9 f5 be f0 8f 72 1c 34 84 1b 11 25 dd 44 8b 99 75 a4 77 3d e1 1d 26 41 58 55 5f d5 27 82 c d3 2a f8 4 aa 8d 5e e4 79 0 49 43 59 27 5e 15 87 a f4 c4 57 b6 e1 f8 79 3b d3 20 69 5e d0 80 6a 6b 9f 43 79 84 94 d0 77 b6 fc f 3 22 ca b9 35 c0 e8 7b e9 25 26 7f c9 fb e4 a7 fc bb b7 75 ac 7b bc f4 bb 4f a8 80 9b 73 da 3 94 da 87 e7 94 4c 80 b3 f1 2e 5b d8 2 65 25 bb 92 f4 92 e3 de 8 ee 2 30 df 84 a4 69 a6 a1 d0 9c e7 8e f 8 71 4b d0 1c 14 ac 7c c6 e3 2a 2e 2a c2 32 bc 21 c4 2f 4d df 9a f3 10 3e e5 c5 7f ad e4 fb ae 99 bf 58 0 20 0 0 0 0 0 0 0 0 0 0 [2013-11-06 15:11:08,602] main - b.b():? - Enterring getResponse [2013-11-06 15:11:08,618] main - b.a():? - Enterring getTimeoutValue(AceRequest AceAuthV4Request[AbstractAceRequest[ hdr=AcePacketHeader[Type=92 Ver=5 AppID=3 Enc=ENCRYPT Hi-Proto=5 Opt=0 CirID=0] created=1383750668571 trailer=AcePackeTrailer[nonce=39e7a607b517c4dd crc=722833884]] user=bmatthews node-sec-req=0 wpcodes=null resp-mac=0 m-resp-mac=0 client=192.168.10.3 passcode==ZTmY|? sec-sgmt=AceSecondarySegments[ cnt=3] response=none]) [2013-11-06 15:11:08,618] main - b.a():? - acm base timeout: 5 [2013-11-06 15:11:08,618] main - b.b():? - Timeout is 5000 [2013-11-06 15:11:08,618] main - b.b():? - Current retries: 0 [2013-11-06 15:11:10,618] main - b.b():? - Received 508 bytes from 192.168.10.121; contents: 6c 5 0 3 3 6 0 0 0 0 0 1 4d 18 55 ca 18 df 84 49 70 ee 24 4a a5 c3 1c 4e 36 d8 51 ad c7 ef 49 89 6e 2e 23 b4 7e 49 73 4 15 d f4 d5 c0 bf fc 72 5b be d1 62 be e0 de 23 56 bf 26 36 7f b f0 ba 42 61 9b 6f 4b 96 88 9c e9 86 df c6 82 e5 4c 36 ee dc 1e d8 a1 0 71 65 89 dc ca ee 87 ae d6 60 c 86 1c e8 ef 9f d9 b9 4c ed 7 55 77 f3 fc 92 61 f9 32 70 6f 32 67 4d fc 17 4e 7b eb c3 c7 8c 64 3f d0 d0 c7 86 ad 4e 21 41 a2 80 dd 35 ba 31 51 e2 a0 ef df 82 52 d0 a8 43 cb 7c 51 c 85 4 c5 b2 ec 8f db e1 21 90 f5 d7 1b d7 14 ca c0 40 c5 41 4e 92 ee 3 ec 57 7 10 45 f3 54 d7 e4 e6 6e 79 89 9a 21 70 7a 3f 20 ab af 68 34 21 b7 1b 25 e1 ab d 9f cd 25 58 5a 59 b1 b8 98 58 2f 79 aa 8a 69 b9 4c c1 7d 36 28 a3 23 f5 cc 2b ab 9e f a1 79 ab 90 fd 5f 76 9f d9 86 d1 fc 4c 7a 4 24 6d de 64 f1 53 22 b0 b7 91 9a 7c a2 67 2a 35 68 83 74 6a 21 ac eb f8 a2 29 53 21 2f 5a 42 d6 26 b8 f6 7f 79 96 5 3b c2 15 3a b d0 46 42 b7 74 4e 1f 6a ad f5 73 70 46 d3 f8 e a3 83 a3 15 29 6e 68 2 df 56 5c 88 8d 6c 2f ab 11 f1 5 73 58 ec 4 5f 80 e3 ca 56 ce 8 b9 73 7c 79 fc 3 ff f1 40 97 bb e3 fb 35 d1 8d ba 23 fc 2d 27 5b f7 be 15 de 72 30 b e d6 5c 98 e8 44 bd ed a4 3d 87 b8 9b 35 e9 64 80 9a 2a 3c a2 cf 3e 39 cb f6 a2 f4 46 c7 92 99 bc f7 4a de 7e 79 9d 9b d9 34 7f df 27 62 4f 5b ef 3a 4c 8d 2e 66 11 f7 8 c3 84 6e 57 ba 2a 76 59 58 78 41 18 66 76 fd 9d cb a2 14 49 e1 59 4a 6e f5 c3 94 ae 1a ba 51 fc 29 54 ba 6c 95 57 6b 20 87 cc b8 dc 5f 48 72 9c c0 2c dd 60 56 4e 4c 6c 1d 40 bd 4 a1 10 4e a4 b1 87 83 dd 1c f2 df 4c [2013-11-06 15:11:10,618] main - a.a():? - Response status is: 1 [2013-11-06 15:11:10,618] main - a.a():? - Authenticaton failed for bmatthews !

• pdf errors with php, apache2

  - by julio

  Hi-- I'm seeing some strange behavior from some dynamically generated PDFs using the TCPDF library in PHP. Standard lamp stack-- however, if you try to open the PDF from Windows with Acrobat Reader, it gives an error that the "file is damaged and could not be repaired". From Mac, Linux, etc. the file works fine, and opens fine. It also opens fine in Google Docs-- so clearly the PDF itself is ok. Is it possible that the mime type (application/pdf) is causing problems in Windows? Thanks

• ffmpeg-php permission denied on localhost

  - by user572271

  Hello, I am very new to php. I recently setup php on my mac and I am trying to setup ffmpeg-php to convert various videos to flv or other formats as desired. I used this tutorial FFmpeg Mac Installation and I got ffmpeg to work using the terminal, however, when I try to encode a movie using php I get an error.

Anyone have any ideas. I have been struggling with setting up ffmpeg for quite some time now. Thanks! -Jon

• Compiling a C program with a specific architecture

  - by Marplesoft

  I was recently fighting some problems trying to compile an open source library on my Mac that depended on another library and got some errors about incompatible library architectures. Can somebody explain the concept behind compiling a C program for a specific architecture? I have seen the -arch compiler flag before and have seen values passed to it such as ppc, i386 and x86_64 which I assume maps to the CPU "language", but my understanding stops there. If one program uses a particular architecture, do all libraries that it loads need to be on the same architecture as well? How can I tell what architecture a given program/process is running under?

• deciding between subprocess, multiprocesser and thread in Python?

  - by user248237

  I'd like to parallelize my Python program so that it can make use of multiple processors on the machine that it runs on. My parallelization is very simple, in that all the parallel "threads" of the program are independent and write their output to separate files. I don't need the threads to exchange information but it is imperative that I know when the threads finish since some steps of my pipeline depend on their output. Portability is important, in that I'd like this to run on any Python version on Mac, Linux and Windows. Given these constraints, which is the most appropriate Python module for implementing this? I am tryign to decide between thread, subprocess and multiprocessing, which all seem to provide related functionality. Any thoughts on this? I'd like the simplest solution that's portable. Thanks.

• The reasons to upgrade from Delphi 2009

  - by Serg

  I have made the question "community wiki" - it is subjective. I have upgraded to Delphi 2009 because of unicode support. I have found the anonymous methods a very interesting and useful language feature, I can't say the same about generics. The generics seemed important for me before the upgrade to Delphi 2009, but I have never used them and probably will never use. As for Delphi 2010, I don't need the attributes and I don't like the whole idea of extended RTTI - that is why Delphi 2009 is better for me. Sometimes I hit one or other annoying bug in Delphi 2009 IDE, but they are not critical and I can live with them. I have no plans to develop software for Mac or Linux. Sure sometime I will need 64-bit support, so I think about upgrading to Delphi 2012. Are where any more reasons that can force me to upgrade from Delphi 2009?

• Why Java SimpleDateFormat().parse() is giving weird formate?

  - by MAK

  My input is String formated as the following: 3/4/2010 10:40:01 AM 3/4/2010 10:38:31 AM My code is: DateFormat dateFormat = new SimpleDateFormat("dd/mm/yyyy hh:mm:ss aa"); try { Date today = dateFormat.parse(time); System.out.println("Date Time : " + today); } catch (ParseException e) { e.printStackTrace(); } the output is: Sun Jan 03 10:38:31 AST 2010 Sun Jan 03 10:40:01 AST 2010 I'm not sure from where the day (Sun) came from? or (AST)? and why the date is wrong? I just wanted to keep the same format of the original String date and make it into a Date object. I'm using Netbeans 6.8 Mac version.

• JUnit: 4.8.1 "Could not find class"

  - by Patrick

  Ok, I am like other and new to jUnit and having a difficult time trying to get it working. I have searched the forum but the answers provided; I am just not getting. If anyone out there could lend me a hand I would greatly appreciate it. Let me provide the basics: OS: mac OS X.6 export JUNIT_HOME="/Developer/junit/junit4.8.1" export CVSROOT="/opt/cvsroot" export PATH="/usr/local/bin:/usr/local/sbin:/usr/localmysql/bin:/opt/PalmSDK/Current/bin/:/usr/local/mysql/bin:$PATH:$JUNIT_HOME:$CVSROOT" export CLASSPATH="$CLASSPATH:$JUNIT_HOME/junit-4.8.1.jar:$JUNIT_HOME" I can compile a test class from a java file, however when I try to then run the test java org.junit.runner.JUnitCore MyTest.class I get the following: JUnit version 4.8.1 Could not find class: MyTest.class Time: 0.001 OK (0 tests) Now I have been in the directory with the MyTest.class which is just somewhere in my file system, I tried moving the source folder to the "junit" folder and the "junit/junit4.8.1" folder and the same result. I cannot even run the tests that came with junit. Thanks patrick

• developing iphone apps on windows is it worth the hassel

  - by kalpaitch

  I'm only after a simple solution and won't be developing anything particularly complex. But I'm wondering whether the hassals of developing an iPhone app NOT on MacOS are really that significant to avoid giving it a shot. Bearing in mind that I do have access to a mac every now and again. So I would be able to compile it using the official Apple supported SDK, but I just want to be able to develop it in my own environment (windows laptop). I heard someone mention a while ago that there are various objective C compilers that allow writing code in various other web technologies as well. Are these really valid. And am I alone in thinking Apple's whole attitude towards this is totally imoral. Charging $200 for the privelege of having your app unequivocally rejected etc etc and then not being allowed to look directly at Steve Jobs or his golden retrievers.

• Reading iTunesMovies file in iPhone?

  - by raziiq

  Hi there. In iPhone, the iPod app saves the media files (audio, video) with strange names and in weird folders (F00,F01 etc). There is a file named iTunesMovies in iPhone, which contains all the information about the metadata of those video files and how they are to be displayed in iPod app. I copied that to my Mac also, and when i tried to open that file in textEdit, it showed some alien characters which made me believe that it is encrypted may be(Thats just a wild guess). I want to read/change the contents of that iTunesMovies file. Can i do that? Is there any Framework which deals with that iTunesMovies file? Thanks in advance

• How do you implement file drag-and-drop upload in Google Chrome?

  - by Chris R

  I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

• Best approach for building a multiplattform graphical interface for a command-line application

  - by Werner

  Hi, I developed a command line application, whose binary runs in Linux, Windows and Mac OSX. It reads some text input files, but I realize that some special users can not handle this. I would then like to build some kind of graphical interface, where the user only finds buttons and scroll bars for selecting the input parameters, a big "run" button, and then it reads the output of the program and makes some figures. I also need that everything gets finally packed in a single file, which uses only static libraries, so the user just needs to copy the file to his/her machine and run it. I would like to know what is the best open source and multi-platform approach to do this. 10 years ago I played a bit with something similar on DEC machines, so I guess that nowadays the situation has probably improved a bit. P.S. For designing the graphical interface, I am looking for a graphical approach, where you add buttons, scroll bars with the mouse P.S. 2: the interface is really simple, just need less than 10 buttons, 5 text fields and 2 scrolla bars Thanks

• cmake, gcc, cuda and -m32 wtf

  - by Nils

  Hi all I figured out that CUDA does not work in 64bit mode on my mac (or couldn't get it running so far). Therefore I decided to compile everything for 32bit. I use cmake 2.8 and added the following options add_definitions(-Wall -m32) set(CUDA_64_BIT_DEVICE_CODE OFF) set(CMAKE_MODULE_LINKER_FLAGS -m32) However when it tries to link it it does something like this: /usr/bin/c++ -mmacosx-version-min=10.6 -Wl,-search_paths_first -headerpad_max_install_names CMakeFiles/SimpleTestsCUDA.dir/BlockMatrix.cpp.o CMakeFiles/SimpleTestsCUDA.dir/Matrix.cpp.o ./SimpleTestsCUDA_generated_SimpleTests.cu.o ./SimpleTestsCUDA_generated_BlockMatrix.cu.o -o SimpleTestsCUDA /usr/local/cuda/lib/libcudart.dylib /usr/local/cuda/lib/libcuda.dylib Which fails with a lot of "file is not of required architecture" warnings from ld. Now if I add manually -m32 to the command above it works. However I have no idea how to teach cmake to add -m32 to every gcc (or ld) invocation. So far it does it for nvcc and gcc, but not for linking..

• Downloading PKPass in an iOS custom app from my server

  - by taurus

  I've setup a server which returns a PKPass. If I copy the URL to the browser, a pass is shown (both in my Mac and in my iPhone). The code I'm using to download the pass is the following one: NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:kAPIPass]]; if (nil != data) { PKPass *pass = [[PKPass alloc] initWithData:data error:nil]; PKAddPassesViewController *pkvc = [[PKAddPassesViewController alloc] initWithPass:pass]; pkvc.delegate = self; [self presentViewController:pkvc animated:YES completion:^{ // Do any cleanup here } ]; } Anyway, when I run this code I have the following error: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Only support RGBA or the White color space, this method is a hack.' I don't know what is the bug... The pass seems ok when I download it with Safari and even the code seems ok (there are just 3 simple rows...) Someone experienced with Passkit could help me? EDIT: the weird thing is that the exact same code is working in a fresh new project

• Flex Error #1014: Class flash.net::NetStreamPlayOptions

  - by evilpenguin

  I have a pure ActionScript project. I'm using Flex Builder on a Mac, Flex SDK 3.4 and I've even added the playerglobal.swc from the Flash folder to the project's library path. I get autocomplete when I add import flash.net.NetStreamPlayOptions; import flash.net.NetStreamPlayTransitions; But when I run the movie, I get: VerifyError: Error #1014: Class flash.net::NetStreamPlayOptions could not be found. I don't get it.. What must I do to use those classes?

• Trouble Installing the new Android SDK

  - by Dan Monego

  I've installed the newest Android SDK using eclipse's software updates feature to hit the resource at https://dl-ssl.google.com/android/eclipse/. After installing it, it seems like the SDK is integrated into Eclipse, but when I try to create a new project with a single blank activity in it, I get the following error: [2009-06-06 11:41:24 - TestProject] no classfiles specified [2009-06-06 11:41:24 - TestProject] Conversion to Dalvik format failed with error 1 This is using eclipse version 3.4.2 running on top of Mac OS 10.5.7 on a 32 bit processor. Is this a misconfiguration on my part? Have I missed a part of the installation?
