  • Circular Shifts on Strings in Bash

    - by Kyle Van Koevering
    I have a homework assignment where I need to take input from a file and continuously remove the first word in a line and append it to the end of the line until all combinations have been done. I really don't know where to begin and would be thankful for any sort of direction. The part that has me confused is that this is suppose to be performed without the use of arrays. I'm not just fishing for someone to solve the problem for me, I'm just looking for some direction. Thank you very much for your time and help.

  • Channel Audio from .mp4?

    - by Kyle
    Hi there. I am at a loss here after searching around with no results. I am attempting to channel the audio specifically from an .mp4 for use in a driver. I am aware that there are programs which extract the audio from .mp4's, but I am looking for another approach without using external applications such as those.. is there any direction that someone can point me towards to solve this problem? Thanks, -K

  • iPhone OpenGL and NSTimer issues

    - by Kyle
    I have an NSTimer that runs at 60hz. With an OpenGL scene loaded and rendering, my game can get 60fps, solid, all day long.. Then if I go and recompile the app, or reload it, it will get 40fps. Same resources loaded. I've been running into this problem for years, and I just want to know why. It's crazy, and I want to know if I should just abandon this stupid Timer. Conditions are not different on my 3GS between loads. It will just get 40fps sometimes. Obviously the clockrate is not different between loads, so the performance figures should be constant given a constant scene. Here is a log of my framerates: A good load: :-) FrameRate: 61 FrameRate: 61 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 61 Now, I'll go ahead and do nothing, recompile, and run: FrameRate: 43 FrameRate: 50 FrameRate: 45 FrameRate: 48 FrameRate: 40 FrameRate: 45 FrameRate: 42 FrameRate: 41 FrameRate: 42 FrameRate: 44 FrameRate: 41 FrameRate: 46 ^- Massive difference visually. What the flying heck could cause this? SAME area of the scene, SAME camera setup. No variables are different.

  • Reading Resource Files from my own APK in Android Native Environment

    - by Kyle
    I'm porting to Android. My existing project has a ton of resource files that I'm porting into my Android project. I have them all in /res/raw/, and I would like to access those resources in my native library with functions such as fopen() and such. Can this be done, or do I have to go through JNI for this as well? I would really prefer not to, for ease of porting and possible speed and memory reasons.

  • Dynamically setting a log4net property using common.logging

    - by Kyle LeNeau
    Does anyone know if there is an equivalent in Common.Logging (for .Net) to set properties for the log4net factory adapter? I have had great success when just using log4net by doing: <appender name="FileAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="logs\Log_%property{BrokerID}.txt"/> <appendToFile value="false"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="-1"/> <maximumFileSize value="50GB"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %-5level %logger - %message%newline"/> </layout> </appender> and setting the property like:log4net.GlobalContext.Properties["BrokerID"] = 10 The file I end up with the looks like this: Log_(null).txt when using the common.logging to wire up log4net on the fly.

  • Dealing with PHP server and MySQL server in different time zones

    - by Kyle Noland
    For those of us who use standard shared hosting packages, such as GoDaddy or Network Solutions, how do you handle datetime conversions when your hosting server (PHP) and MySQL server are in different time zones? Also, does anybody have some best practice advice for determining what time zone a visitor to your site is in and manipulating a datetime variable appropriately?

  • Entry lvl. COBOL Control Breaks

    - by Kyle Benzle
    I'm working in COBOL with a double control break to print a hospital record. The input is one record per line, with, hospital info first, then patient info. There are multiple records per hospital, and multiple services per patient. The idea is, using a double control break, to print one hospital name, then all the patients from that hospital. Then print the patient name just once for all services, like the below. I'm having trouble with my output, and am hoping someone can help me get it in order. I am using AccuCobol to compile experts-exchange does not allow .cob and .dat so the extentions were changed to .txt The files are: the .cob lab5b.cob the input / output: lab5bin.dat, lab5bout.dat The assignment: http://www.cse.ohio-state.edu/~sgomori/314/lab5.html Hospital Number: 001 Hospital Name: Mount Carmel 00001 Griese, Brian Ear Infection 08/24/1999 300.00 Diaper Rash 09/05/1999 25.00 Frontal Labotomy 09/25/1999 25,000.00 Rear Labotomy 09/26/1999 25,000.00 Central Labotomy 09/28/1999 24,999.99 The total amount owed for this patient is: $..........

  • Talking to an Authentication Server

    - by Kyle Terry
    I'm building my startup and I'm thinking ahead for shared use of services. So far I want to allow people who have a user account on one app to be able to use the same user account on another app. This means I will have to build an authentication server. I would like some opinions on how to allow an app to talk to the authentication server. Should I use curl? Should I use Python's http libs? All the code will be in Python. All it's going to do is ask the authentication server if the person is allowed to use that app and the auth server will return a JSON user object. All authorization (roles and resources) will be app independent, so this app will not have to handle that. Sorry if this seems a bit newbish; this is the first time I have separated authentication from the actual application.

  • Practical non-Turing-complete languages?

    - by Kyle Cronin
    Nearly all programming languages used are Turing Complete, and while this affords the language to represent any computable algorithm, it also comes with its own set of problems. Seeing as all the algorithms I write are intended to halt, I would like to be able to represent them in a language that guarantees they will halt. Regular expressions used for matching strings and finite state machines are used when lexing, but I'm wondering if there's a more general, broadly language that's not Turing complete? edit: I should clarify, by 'general purpose' I don't necessarily want to be able to write all halting algorithms in the language (I don't think that such a language would exist) but I suspect that there are common threads in halting proofs that can be generalized to produce a language in which all algorithms are guaranteed to halt. There's also another way to tackle this problem - eliminate the need for theoretically infinite memory. Once you limit the amount of memory the machine is allowed, the number of states the machine is in is finite and countable, and therefore you can determine if the algorithm will halt (by not allowing the machine to move into a state it's been in before).

  • Create a thumbnail of a dwg in in a linux envrionment

    - by Kyle
    Creating a ruby on rails site that uses RMagick to create thumbnails for many types of images. RMagick cannot read dwg files however. I've tried a few things, looked into the Java library JDWGLib, which would probably allow me to write a converter, but it would be a total from the ground up solution, where I just need a thumbnail. Also considered using a viewer program to open the file in a remote X session and do a screen capture, however I'm not sure how I could ever guarantee that the viewer had completed opening when I took the screenshot. I'm not concerned with being able to manipulate the file other than to create the thumbnail. It is going to be used for commercial purposes, so any libraries used need to be compatible.

  • Does height and width not apply to span?

    - by Kyle Sevenoaks
    Total noob question, but here. CSS .product__specfield_8_arrow { /*background-image:url(../../upload/orng_bg_arrow.png); background-repeat:no-repeat;*/ background-color:#fc0; width:50px !important; height:33px !important; border: 1px solid #dddddd; border-left:none; border-radius:5px; -moz-border-radius:5px; -webkit-border-radius:5px; border-bottom-left-radius:0px; border-top-left-radius:0px; -moz-border-radius-bottomleft:0px; -moz-border-radius-topleft:0px; -webkit-border-bottom-left-radius:0px; -webkit-border-top-left-radius:0px; margin:0; padding:2px; cursor:pointer; }??? HTML <span class="product__specfield_8_arrow">&nbsp;</span>? Fiddle Basically I'm trying to emulate a button, make a span (or something) look like a button next to an input field that actually doesn't need to be one because of an auto fill generator that generates errors onEnter. Thought this'd be a quick fix for now but obviously not. Thanks.

  • PHP find .tpl files

    - by Kyle Sevenoaks
    Hi, I have some errors in my output source code, I'm wondering if there is a tool that is able to look through the site and find which .tpl file my error is in? That, or at least give me a list of .tpls to look through. I can't seem to find this error and the site isn't very well documented. I'm not the best PHP programmer, I'd be looking for an online resource or something pretty simple. Thanks very much.

  • Calling linux utilities with options from within a Bash script.

    - by Kyle
    This is my first Bash script so forgive me if this question is trivial. I need to count the number of files within a specified directory $HOME/.junk. I thought this would be simple and assumed the following would work: numfiles= find $HOME/.junk -type f | wc -l echo "There are $numfiles files in the .junk directory." Typing find $HOME/.junk -type f | wc -l at the command line works exactly how I expected it to, simply returning the number of files. Why is this not working when it is entered within my script? Am I missing some special notation when it comes to passing options to the utilities? Thank you very much for your time and help.

  • Location of the fonts on the iPhone?

    - by Kyle
    I'm using the FreeType2 library in an iPhone project, and I'm trying to simply load a TTF file from the system, if possible. FT_Library library; FT_Face face; int error; error = FT_Init_FreeType( &library ); if ( error == 0 ) printf("Initialized FreeType2\r\n"); /* Prints */ error = FT_New_Face(library, "/System/Library/Fonts/Helvetica.ttf", 0, &face); if ( error == FT_Err_Cannot_Open_Resource ) printf("Font not found\r\n"); /* Prints */ That error seems to be for file not found. Is /System/Library/Fonts not the location of the fonts? Or, do iPhone apps simply not have any read access at all to that directory. Thanks!

  • mcrypt decoding errors

    - by Kyle Hudson
    Hi, I have a few issues with the following php functions (part of a bigger class). //encode public function acc_pw_enc($text, $key) { $text_num = str_split($text, 8); $text_num = 8 - strlen($text_num[count($text_num)-1]); for ($i=0; $i < $text_num; $i++) { $text = $text . chr($text_num); } $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', ''); mcrypt_generic_init($cipher, $key, 'fYfhHeDm'); $decrypted = mcrypt_generic($cipher, $text); mcrypt_generic_deinit($cipher); return base64_encode($decrypted); } //decode public function acc_pw_dec($encrypted_text, $key) { $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', ''); mcrypt_generic_init($cipher, $key, 'fYfhHeDm'); $decrypted = mdecrypt_generic($cipher, base64_decode($encrypted_text)); mcrypt_generic_deinit($cipher); $last_char = substr($decrypted, -1); for($i=0; $i < 8-1; $i++) { if(chr($i) == $last_char) { $decrypted = substr($decrypted, 0, strlen($decrypted)-$i); break; } } return rtrim($decrypted); //str_replace("?", "", $decrypted); } So for exampe if i encrypt the string 'liloMIA01' with the salt/key 'yBevuZoMy' i will get '7A30ZkEjYbDcAXLgGE/6nQ=='. I get liloMIA01 as the decrypted value, i tried using rtrim but it didn't work.

  • Removing active class and adding it to a sibling

    - by Kyle
    Currently, I have a jQuery Cycle plugin that allows the image to scroll. With it's callback I am calling this function function onAfterVideoScroll() { $('.myRemote.active').removeClass("active").next().addClass("active"); } This SHOULD be removing the current class from another set of links, and adding the class to the it's next sibling. This is to keep whichever image is showing it's button predecessor will be active so the user can tell which button is currently showing on the slideshow. If this makes sense, please let me know why it will remove the active class but it never gives the sibling the active class. Thanks!

  • What is the proper use of boost::fusion::push_back?

    - by Kyle
    // ... snipped includes for iostream and fusion ... namespace fusion = boost::fusion; class Base { protected: int x; public: Base() : x(0) {} void chug() { x++; cout << "I'm a base.. x is now " << x << endl; } }; class Alpha : public Base { public: void chug() { x += 2; cout << "Hi, I'm an alpha, x is now " << x << endl; } }; class Bravo : public Base { public: void chug() { x += 3; cout << "Hello, I'm a bravo; x is now " << x << endl; } }; struct chug { template<typename T> void operator()(T& t) const { t->chug(); } }; int main() { typedef fusion::vector<Base*, Alpha*, Bravo*, Base*> Stuff; Stuff stuff(new Base, new Alpha, new Bravo, new Base); fusion::for_each(stuff, chug()); // Mutates each element in stuff as expected /* Output: I'm a base.. x is now 1 Hi, I'm an alpha, x is now 2 Hello, I'm a bravo; x is now 3 I'm a base.. x is now 1 */ cout << endl; // If I don't put 'const' in front of Stuff... typedef fusion::result_of::push_back<const Stuff, Alpha*>::type NewStuff; // ... then this complains because it wants stuff to be const: NewStuff newStuff = fusion::push_back(stuff, new Alpha); // ... But since stuff is now const, I can no longer mutate its elements :( fusion::for_each(newStuff, chug()); return 0; }; How do I get for_each(newStuff, chug()) to work? (Note: I'm only assuming from the overly brief documentation on boost::fusion that I am supposed to create a new vector every time I call push_back.)

  • jQuery event handling with .live() problem with setInterval and clearInterval

    - by Kyle Lafkoff
    jQuery 1.4.2: I have an image. When the mouseover event is triggered, a function is executed that runs a loop to load several images. On the contrary, the mouseout event needs to set the image back to a predetermined image and no longer have the loop executing. These are only for the images with class "thumb": $("img.thumb").live("mouseover mouseout", function(event) { var foo = $(this).attr('id'); var wait; var i=0; var image = document.getElementById(foo); if (event.type == 'mouseover') { function incrementimage() { i++; image.src = 'http://example.com/images/file_'+i+'.jpg'; if(i==30) {i=0;} } wait = setInterval(incrementimage,500); } else if (event.type == 'mouseout') { clearInterval (wait); image.src = 'http://example.com/images/default.jpg'; } return false; }); When I mouseout, the image is set to the default.jpg but the browser continues to loop though the images. It will never stop. Can someone hit me with some knowledge? Thanks.
