  • RaphaelJS HTML5 Library pathIntersection() bug or alternative optimisation (screenshots)

    - by user1236048
    I have a chart generated using RaphaelJS library.

I want when I move the slider to move a dot on the chart accordingly with the slider position. See attached screenshot: As you can see it seems to work fine. I've implemented this behaviour using the pathIntersection() method. On the slide event at each ui.value (x coordinate) I intersect my chartPath (the one from above) with a vertical straight line at the x coordinate. But still there are some problems. One of them is that it runs very hard, and it kinda freezes sometimes.. and very weird sometimes it doesn't seem to intersect at all even it should.. I'll example below 2 cases I identified: M 499.8461538461538 0 L 499.8461538461538 140 M 910 0 L 910 140 Could you please explain why this intersect behaviour happens (it should return a dot).. and the worst part it seems like it happens randomly.. if I use another chartdata. Also if you can identify another (better) solution to syncronise the slider position with the dot on the chart.. would be perfect. I thought about using Element.getPointAtLength(length), but I don't know how. I think I should save the pathSegments and for each to compute the start Length and the finish Length.

  • Can I use a project code which has New BSD license but uses a GPL license library?

    - by Alok Kulkarni
    I want to use the ICSOpenVpn project source code in my commercial application. If we see the ICSOpenVpn project, it states that its license is New BSD but the libopenvpn.so library it uses is under GNU GPLv2 license. As per FAQ for version 2 of GNU GPL "If a library is released under the GPL (not the LGPL), does that mean that any program which uses it has to be under the GPL?" The answer says: "Yes, because the program as it is actually run includes the library." Also, how could ICSOpenVpn change the license to New BSD?

  • UDK/ UnrealScript class interaction? HUD advice?

    - by Holly
    Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

  • How to export a C++ class library to C# using a dll?

    - by SICGames2013
    In my previous revision game engine I deported major functions for the game editor for C#. Now, I'm beginning to revise the game engine with a static library. There's a already dynamic library created in C++ to use DLLEXPORT for C#. Just now I want to test out the newer functions and created a DLL file from C++. Because the DLL contains classes I was wondering how would I be able to use DLL Export. Would I do this: [DLLEXPORT("GameEngine.dll", EntryPoint="SomeClass", Conventional=_stdcall)] static extern void functionFromClass(); I have a feeling it's probably DLLImport and not DLLExport. I was wondering how would I go about this? Another way I was thinking was because I already have the DLL in C++ prepared already to go the C# Class Library. I could just keep the new engine as a lib, and link the lib with the old DLL C++ file. Wouldn't the EntryPoint be able to point to the class the function is in?

  • Contract Programming - Deposit % and Payment Methods? Any advice is appreciated

    - by Rick
    I'm pretty new to doing contract work and finally landed a decent paying project. The guy actually offered to put down a deposit and I'm just wondering what percentage I should consider asking for. I was thinking around 25% since its not a terribly large project (only about 20 hours). Also, I can't use PayPal (have had a terrible experience with them freezing funds for no good reason) so I'm wondering if anyone can suggest other methods for the client to send the deposit / payment. I want to make it as easy as possible for them.. thanks for any advice

  • Is the escaping provided by the Google-Gson library enough to ensure a safe JSON payload?

    - by Lifetime_Learner
    I am currently using the Google-Gson library to convert Java objects into JSON inside a web service. Once the object has been converted to JSON, it is returned to the client to be converted into a JSON object using the JavaScript eval() function. Is the character escaping provided by the Gson library enough to ensure that nothing nasty will happen when I run the eval() function on the JSON payload? Do I need to HTML Encode the Strings in the Java Objects before passing them to the Gson library? Are there any other security concerns that I should be aware of?

  • Computer Science Career Advice: Master's in Computer Science vs. Software Engineering?

    - by Everton
    Hello, I am a college student and I am majoring in Computer Science and Applied Mathematics. As I get closer to my senior year I have noticed that continuing my studies is the best choice right for me now. I see that several universities offer an Computer Science Master's Degree and an Software Engineering degree. What are their pros and cons? I feel that while the Computer Science master's degree seems a little too broad the Software Engineering is too restrictive. I did not decide yet between an career of Software development or research ( algorithm development among other things ). Any advice would be greatly apreciated!

  • Do I have to release the code of a MIT licensed software running a GPL library?

    - by Belohlavek
    Lets say I'm using Node-Webkit, an MIT licensed app runtime. Now, let's say I decide to include a Javascript library which is GPL licensed: while I do not modify the downloaded JS file, I do write my own code making use of the library's functions. I plan to sell the final obfuscated executable and I'm wondering: what's the final license of the complete software? Do I only have to release the GPL library or does the GPL license apply for all the code I wrote? What happens to Node-Webkit's MIT license?

  • What's your advice for getting Oracle Certified Professional Java Programmer certificate?

    - by den-javamaniac
    Hi. I intend to get the certification but am not completely sure how to effectively prepare myself. So I'm wondering if you have any advice on the matter; in particular I would like to know: - What should the basic learning/practicing plan look like? - Which book (set of books) should be considered? - Which practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

  • How can you build a C++ library to produce a .lib file for use in another project?

    - by Codereview
    I tried to use Cmake for the first time, I tried adding a library to my project (Specifically, PhysFS) but then I understood that the library had no .lib file or .a file at all, so I have to build those somehow. I have no clue where to even start around going this, what should I do? Someone suggested I'd go to the project folder and type "Cmake ..." then "Make ..." but I was clueless as to how I'd do that. How would I build the library headers and source files in a .lib file that I can link in C::B? I'm using Windows XP SP3

  • Can I get some advice on graphics cards please?

    - by Victor9098
    I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

  • C++: Platform independent game lib?

    - by Martijn Courteaux
    Hi, I want to write a serious 2D game, and it would be nice if I have a version for Linux and one for Windows (and eventually OSX). Java is fantastic because it is platform independent. But Java is too slow to write a serious game. So, I thought to write it in C++. But C++ isn't very cross-platform friendly. I can find game libraries for Windows and libraries for Linux, but I'm searching one that I can use for both, by recompiling the source on a Windows platform and on a Linux platform. Are there engines for this or is this idea irrelevant? Isn't it that easy (recompiling)? Any advice and information about C++ libraries would be very very very appreciated!

  • Is it possible to wrap calls to statically linked 3rd party library?

    - by robusta
    Hi, I would like to trace calls to some 3rd party library which are made from another 3rd party library. Example: I want to trace calls to library A. My application statically links library B, which in turn is statically linked to library A. In case of dynamic linking I could write library A2 with wrappers for functions which I want to trace of library A and use LD_PRELOAD=A2.so. Then, my wrappers will be called instead, and I will see the trace. In my case I cannot use dynamic linking. Is it possible to achieve the same using static linking? Thanks, Robusta

  • Python bindings for a vala library

    - by celil
    I am trying to create python bindings to a vala library using the following IBM tutorial as a reference. My initial directory has the following two files: test.vala using GLib; namespace Test { public class Test : Object { public int sum(int x, int y) { return x + y; } } } test.override %% headers #include <Python.h> #include "pygobject.h" #include "test.h" %% modulename test %% import gobject.GObject as PyGObject_Type %% ignore-glob *_get_type %% and try to build the python module source test_wrap.c using the following code build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c However, the last command fails with an error $ ./build.sh Traceback (most recent call last): File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1720, in <module> sys.exit(main(sys.argv)) File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1672, in main o = override.Overrides(arg) File "/usr/share/pygobject/2.0/codegen/override.py", line 52, in __init__ self.handle_file(filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 84, in handle_file self.__parse_override(buf, startline, filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 96, in __parse_override command = words[0] IndexError: list index out of range Is this a bug in pygobject, or is something wrong with my setup? What is the best way to call code written in vala from python? EDIT: Removing the extra line fixed the current problem, but now as I proceed to build the python module, I am facing another problem. Adding the following C file to the existing two in the directory: test_module.c #include <Python.h> void test_register_classes (PyObject *d); extern PyMethodDef test_functions[]; DL_EXPORT(void) inittest(void) { PyObject *m, *d; init_pygobject(); m = Py_InitModule("test", test_functions); d = PyModule_GetDict(m); test_register_classes(d); if (PyErr_Occurred ()) { Py_FatalError ("can't initialise module test"); } } and building with the following script build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c CFLAGS="`pkg-config --cflags pygobject-2.0` -I/usr/include/python2.6/ -I."

  • JavaScript String Library - Hitting a Minor Roadblock

    - by OneNerd
    Ok - am trying to create a string library that contains a handful of useful things missing from JavaScript. Here is what I have so far: ;function $__STRING__$(in_string) { /* internal functions */ this.s = in_string; this.toString = function(){return this.s;}; /******* these functions CAN be chained (they return the $__STRING__$ object) ******/ this.uppercase = function(){this.s = this.s.toUpperCase(); return this;}; this.lowercase = function(){this.s = this.s.toLowerCase(); return this;}; this.trim = function(){this.s = this.s.replace(/^\s+|\s+$/g,""); return this;}; this.ltrim = function(){this.s = this.s.replace(/^\s+/,""); return this;}; this.rtrim = function(){this.s = this.s.replace(/\s+$/,""); return this;}; this.striptags = function(){this.s = this.s.replace(/<\/?[^>]+(>|$)/g, ""); return this;}; this.escapetags = function(){this.s = this.s.replace(/</g,"<").replace(/>/g,">"); return this;}; this.unescapetags = function(){this.s = this.s.replace(/</g,"<").replace(/>/g,">"); return this;}; this.underscorize = function(){this.s = this.s.replace(/ /g,"_"); return this;}; this.dasherize = function(){this.s = this.s.replace(/ /g,"-"); return this;}; this.spacify = function(){this.s = this.s.replace(/_/g," "); return this;}; this.left = function(length){this.s = this.s.substring(length,0); return this;}; this.right = function(length){this.s = this.s.substring(this.s.length,this.s.length-length); return this;}; this.shorten = function(length){if(this.s.length<=length){return this.s;}else{this.left(this.s,length)+"..."; return this;}}; this.mid = function(start,length){return this.s.substring(start,(length+start));}; this._down = function(){return this.s;}; // breaks chain, but lets you run core js string functions /******* these functions CANNOT be chained (they do not return the $__STRING__$ object) ******/ this.contains = function(needle){if(this.s.indexOf(needle)!==-1){return true;}else{return false;}}; this.startswith = function(needle){if(this.left(this.s,needle.length)==needle){return true;}else{return false;}}; this.endswith = function(needle){if(this.right(this.s,needle.length)==needle){return true;}else{return false;};}; } function $E(in_string){return new $__STRING__$(in_string);} String.prototype._enhance = function(){return new $__STRING__$(this);}; String.prototype._up = function(){return new $__STRING__$(this);}; It works fairly well, and I can chain commands etc. I set it up so I can cast a string as an enhanced string these 2 ways: $E('some string'); 'some string'._enhance(); However, each time I want to use a built-in string method, I need to convert it back to a string first. So for now, I put in _down() and _up() methods like so: alert( $E("hello man").uppercase()._down().replace("N", "Y")._up().dasherize() ); alert( "hello man"._enhance().uppercase()._down().replace("N", "Y")._up().dasherize() ); It works fine, but what I really want to do it be able to use all of the built-in functions a string can use. I realize I can just replicate each function inside my object, but I was hoping there was a simpler way. So question is, is there an easy way to do that? Thanks -

  • Deploying a PHP Library project with Maven

    Hi, I've created a PHP Library project using Maven, and I'm now ready for its deployment. Following the instructions at http://www.php-maven.org/deploy.html, something went wrong. The configuration is set to: <descriptorRef>php-lib</descriptorRef> During the execution of mvn deploy I get a list of errors for unfound dependencies in the repository: [INFO] [jar:jar {execution: default-jar}] [INFO] Building jar: /home/marco/projects/php/my-app/target/my-app-1.0-SNAPSHOT.jar [INFO] [plugin:addPluginArtifactMetadata {execution: default-addPluginArtifactMetadata}] Downloading: http://repo1.php-maven.org/release/org/phpmaven/maven-php-plugin/2.2-beta-2/maven-php-plugin-2.2-beta-2.pom [INFO] Unable to find resource 'org.phpmaven:maven-php-plugin:pom:2.2-beta-2' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.maven.org/maven2/org/phpmaven/maven-php-plugin/2.2-beta-2/maven-php-plugin-2.2-beta-2.pom [INFO] Unable to find resource 'org.phpmaven:maven-php-plugin:pom:2.2-beta-2' in repository central (http://repo1.maven.org/maven2) Downloading: http://repo1.php-maven.org/release/org/phpmaven/maven-php-plugin/2.2-beta-2/maven-php-plugin-2.2-beta-2.pom [INFO] Unable to find resource 'org.phpmaven:maven-php-plugin:pom:2.2-beta-2' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.maven.org/maven2/org/phpmaven/maven-php-plugin/2.2-beta-2/maven-php-plugin-2.2-beta-2.pom [INFO] Unable to find resource 'org.phpmaven:maven-php-plugin:pom:2.2-beta-2' in repository central (http://repo1.maven.org/maven2) Downloading: http://repo1.php-maven.org/release/org/apache/maven/wagon/wagon-http-shared/1.0-beta-6/wagon-http-shared-1.0-beta-6.pom [INFO] Unable to find resource 'org.apache.maven.wagon:wagon-http-shared:pom:1.0-beta-6' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.php-maven.org/release/org/apache/maven/wagon/wagon-http-shared/1.0-beta-6/wagon-http-shared-1.0-beta-6.pom [INFO] Unable to find resource 'org.apache.maven.wagon:wagon-http-shared:pom:1.0-beta-6' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.maven.org/maven2/org/apache/maven/wagon/wagon-http-shared/1.0-beta-6/wagon-http-shared-1.0-beta-6.pom Downloading: http://repo1.php-maven.org/release/nekohtml/xercesMinimal/1.9.6.2/xercesMinimal-1.9.6.2.pom [INFO] Unable to find resource 'nekohtml:xercesMinimal:pom:1.9.6.2' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.php-maven.org/release/nekohtml/xercesMinimal/1.9.6.2/xercesMinimal-1.9.6.2.pom [INFO] Unable to find resource 'nekohtml:xercesMinimal:pom:1.9.6.2' in repository release-repo1.php-maven.org (http://repo1.php-maven.org/release) Downloading: http://repo1.maven.org/maven2/nekohtml/xercesMinimal/1.9.6.2/xercesMinimal-1.9.6.2.pom And this is my settings.xml file: <settings> <profiles> <profile> <id>profile-php-maven</id> <pluginRepositories> <pluginRepository> <id>release-repo1.php-maven.org</id> <name>PHP-Maven 2 Release Repository</name> <url>http://repo1.php-maven.org/release</url> <releases> <enabled>true</enabled> </releases> </pluginRepository> <pluginRepository> <id>snapshot-repo1.php-maven.org</id> <name>PHP-Maven 2 Snapshot Repository</name> <url>http://repo1.php-maven.org/snapshot</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> <repositories> <repository> <id>release-repo1.php-maven.org</id> <name>PHP-Maven 2 Release Repository</name> <url>http://repo1.php-maven.org/release</url> <releases> <enabled>true</enabled> </releases> </repository> <repository> <id>snapshot-repo1.php-maven.org</id> <name>PHP-Maven 2 Snapshot Repository</name> <url>http://repo1.php-maven.org/snapshot</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> </profile> </profiles> <activeProfiles> <activeProfile>profile-php-maven</activeProfile> </activeProfiles> </settings> For every step I've followed the documentation (which is poor, though). Any tips? Thanks

  • Any ccTalk libraries available?

    - by fretje
    I want to integrate a coin acceptor into one of our applications. This specific coin acceptor uses the ccTalk protocol (specs here). I've been looking for a ccTalk library which I can use from C#, but until this point I've only found this open source project which seems not quite ready, and abandoned. Any of you guys know of any ccTalk libraries out there? I can't believe this hasn't been done before. It doesn't necessarily has to be free.

  • Convert Bitmap Files into JPEG using the GD library in PHP

    - by Daniel P
    I have been trying to figure out a way to convert bitmap files into a JPEG using the GD library in PHP. I have tried numerous implementations but nothing seems to work. I have tried to tell my client that they should not use Bitmap files but he insists and quite frankly does not comprehend enough about computers to convert them to JPG on his own. I can not use ImageMagick on this server and I need a pure GD solution. Thank you in advance for any and all help. EDIT: The bitmap images that are being used are 16-bit and that is where the problem is occurring. I have this function that I have working .... kinda: function ImageCreateFromBMP($filename) { if (! $f1 = fopen($filename,"rb")) return FALSE; $FILE = unpack("vfile_type/Vfile_size/Vreserved/Vbitmap_offset", fread($f1,14)); if ($FILE['file_type'] != 19778) return FALSE; $BMP = unpack('Vheader_size/Vwidth/Vheight/vplanes/vbits_per_pixel'. '/Vcompression/Vsize_bitmap/Vhoriz_resolution'. '/Vvert_resolution/Vcolors_used/Vcolors_important', fread($f1,40)); $BMP['colors'] = pow(2,$BMP['bits_per_pixel']); if ($BMP['size_bitmap'] == 0) $BMP['size_bitmap'] = $FILE['file_size'] - $FILE['bitmap_offset']; $BMP['bytes_per_pixel'] = $BMP['bits_per_pixel']/8; $BMP['bytes_per_pixel2'] = ceil($BMP['bytes_per_pixel']); $BMP['decal'] = ($BMP['width']*$BMP['bytes_per_pixel']/4); $BMP['decal'] -= floor($BMP['width']*$BMP['bytes_per_pixel']/4); $BMP['decal'] = 4-(4*$BMP['decal']); if ($BMP['decal'] == 4) $BMP['decal'] = 0; $PALETTE = array(); if ($BMP['colors'] < 16777216 && $BMP['colors'] != 65536) { $PALETTE = unpack('V'.$BMP['colors'], fread($f1,$BMP['colors']*4)); } $IMG = fread($f1,$BMP['size_bitmap']); $VIDE = chr(0); $res = imagecreatetruecolor($BMP['width'],$BMP['height']); $P = 0; $Y = $BMP['height']-1; while ($Y >= 0) { $X=0; while ($X < $BMP['width']) { if ($BMP['bits_per_pixel'] == 24) $COLOR = unpack("V",substr($IMG,$P,3).$VIDE); elseif ($BMP['bits_per_pixel'] == 16) { $COLOR = unpack("v",substr($IMG,$P,2)); $blue = ($COLOR[1] & 0x001f) << 3; $green = ($COLOR[1] & 0x07e0) >> 3; $red = ($COLOR[1] & 0xf800) >> 8; $COLOR[1] = $red * 65536 + $green * 256 + $blue; } elseif ($BMP['bits_per_pixel'] == 8) { $COLOR = unpack("n",$VIDE.substr($IMG,$P,1)); $COLOR[1] = $PALETTE[$COLOR[1]+1]; } elseif ($BMP['bits_per_pixel'] == 4) { $COLOR = unpack("n",$VIDE.substr($IMG,floor($P),1)); if (($P*2)%2 == 0) $COLOR[1] = ($COLOR[1] >> 4) ; else $COLOR[1] = ($COLOR[1] & 0x0F); $COLOR[1] = $PALETTE[$COLOR[1]+1]; } elseif ($BMP['bits_per_pixel'] == 1) { $COLOR = unpack("n",$VIDE.substr($IMG,floor($P),1)); if (($P*8)%8 == 0) $COLOR[1] = $COLOR[1] >>7; elseif (($P*8)%8 == 1) $COLOR[1] = ($COLOR[1] & 0x40)>>6; elseif (($P*8)%8 == 2) $COLOR[1] = ($COLOR[1] & 0x20)>>5; elseif (($P*8)%8 == 3) $COLOR[1] = ($COLOR[1] & 0x10)>>4; elseif (($P*8)%8 == 4) $COLOR[1] = ($COLOR[1] & 0x8)>>3; elseif (($P*8)%8 == 5) $COLOR[1] = ($COLOR[1] & 0x4)>>2; elseif (($P*8)%8 == 6) $COLOR[1] = ($COLOR[1] & 0x2)>>1; elseif (($P*8)%8 == 7) $COLOR[1] = ($COLOR[1] & 0x1); $COLOR[1] = $PALETTE[$COLOR[1]+1]; } else return FALSE; imagesetpixel($res,$X,$Y,$COLOR[1]); $X++; $P += $BMP['bytes_per_pixel']; } $Y--; $P+=$BMP['decal']; } fclose($f1); return $res; } The resulting image is this: If you look at the image on the left hand side you can see that the resulting image is not correctly lined up. The little sliver belongs on the right hand side. Where is the code going wrong? The problem is occurring in the 16-bit else-if. Thank you again for all the help.
