• How can I record and save flash video's with an H264 codec

  - by JimHendriks

  Right now I am working on an AIR 3.2 application which lets you stream a video to a Flash Media Server and saves it on a hard drive. This sequence works fine with the standard Sorenson codec but I want to use H.264 for my videos. I found lots example c ode and implemented it in my code, but when I record a video of myself I am unable to re-watch it afterwards. I found how to implement a H.264 encoding in a realeyes blog post here. My code is here. It saves the video as a .f4v file, but my browser (I've tried the latest versions of both Chrome and Firefox, with the latest Flash) and also VLC are unable to load the video. I also used a program called Movie Player which is able to open the file but can only show the first frame and the audio. Neither am I able to upload the video to YouTube because they do not support the file extension. Here is an example video file it saved: H264Test1.f4v. My question is: How do I stream and save the movie with a file extension that I am able to re-watch while using the H.264 codec?

• What are the first steps in C#/.NET development?

  - by paxdiablo

  Okay, I'm biting the bullet and deciding to get into the whole Microsoft/C#/.NET culture and I'm going to do this by putting together a simple (hah!) application. It will basically be an application in which I want to store images and associate with them other optional things. It must be able to import images from the filesystem (and hopefully camera/scanner) then allow the user to add text, audio and other information. I plan to store the images and auxillary information into a database. What the application will do with said data isn't important (yet). Keep in mind I know absolutely nothing about C# or .NET although, as an old codger, I know a great deal about many other things and will regale you with stories and anecdotes until you quietly slip away :-) What are the first steps to take in developing such an application? I've already set out UI layouts and likely process flows although it may be that the development environment dictates changes. Development environment is currently XP SP3 + VS2008 (though I can upgrade if absolutely necessary). What should I be looking at as the first step? Are there any gotchas I should be looking out for?

• How to prevent VC++ 9 linker from linking unnecessary global variables?

  - by sharptooth

  I'm playing with function-level linking in VC++. I've enabled /OPT:REF and /OPT:ICF and the linker is happy to eliminate all unused functions. Not so with variables. The following code is to demonstrate the problem only, I fully understand that actually having code structured that way is suboptimal. //A.cpp SomeType variable1; //B.cpp extern SomeType variable1; SomeType variable2; class ClassInB { //actually uses variable1 }; //C.cpp extern SomeType variable2; class ClassInC { //actually uses variable2; }; All those files are compiled into a static lib. The consumer project only uses ClassInC and links to the static library. Now comes the VC++ 9 linker. First the linker sees that C.obj references variable2 and includes B.obj. B.obj references variable1, so it includes A.obj. Then the unreferenced stuff elimination phase starts. It removes all functions in A.obj and B.obj, but not the variables. Both variable and variable2 are preserved together with their static initializers and deinitializers. That inflates the image size and introduces a delay for running the initializers and deinitializes. The code above is oversimplified, in actual code I really can't move variable2 into C.cpp easily. I could put it into a separate .cpp file, but that looks really dumb. Is there any better option to resolve the problem with Visual C++ 9?

• Writing a program which uses voice recogniton... where should I start?

  - by Katsideswide

  Hello! I'm a design student currently dabbling with Arduino code (based on c/c++) and flash AS3. What I want to do is to be able to write a program with a voice control input. So, program prompts user to spell a word. The user spells out the word. The program recognizes if this is right, adds one to a score if it's correct, and corrects the user if it's wrong. So I'm seeing a big list of words, each with an audio file of the word being read out, with the voice recognition part checking to see if the reply matches the input. Ideally i'd like to be able to interface this with an Arduino microcontroller so that a physical output with a motor could be achieved in reaction also. Thing is i'm not sure if I can make this program in flash, in Processing (associated with arduino) or if I need another CS3 program-making-program. I guess I need to download a good voice recognizing program, but how can I interface this with anything else? Also, I'm on a mac. (not sure if this makes a difference) I apologize for my cluelessness, any hints would be great! -Susan

• Youtube Javascript API play(); not working.. what am I doing wrong?

  - by odpogn

  Hello, I'm playing around with YouTubes Javascript API. I've set up a test page on my local enviornment, but the play function is not working. The video loads, and I can press play on the yt video screen, but my link "play" isn't working. Can someone tell me what I'm doing wrong?? I've been following this: http://code.google.com/apis/youtube/js_api_reference.html <html> <head> <script type="text/javascript" src="public/javascripts/swfobject.js"></script> </head> <body> <div id="ytapiplayer"> You will need Flash 8 or better to view this content. </div> <script type="text/javascript"> var params = { allowScriptAccess: "always" }; var atts = { id: "myytplayer" }; swfobject.embedSWF("http://www.youtube.com/v/OQSNhk5ICTI&enablejsapi=1&playerapiid=ytplayer", "ytapiplayer", "425", "365", "8", null, null, params, atts); function onYouTubePlayerReady(playerId) { ytplayer = document.getElementById("myytplayer"); } function play() { if (ytplayer) { ytplayer.playVideo(); } } </script> <a href="javascript:void(0);" onclick="play();">Play</a> </body> </html>

• Getting the eventargs of registered events

  - by Bjorn Vdkerckhove

  i'm new with maps and openlayers, but i'm playing around with openlayers because i'll need mapfunctionality in my next project. The map is an image (because it's a drawn map of a medieval town). I found how i can register events, and it's working. But the problem is, that the "eventargs" is not working as in the examples i found. In one of the examples they are getting the x and y values after the users panned like this: map.events.register('moveend', map, function (e) { alert(e.xy); }); If i try this in visual studio, e doesn't have a 'xy' property. What am i missing? This is the code i have right now: <script type="text/javascript"> var map, layer; function init() { var windowHeight = $(window).height(); var windowWidth = $(window).width(); var mapdiv = $('#map'); mapdiv.css({width: windowWidth + 'px', height: windowHeight + 'px'}); map = new OpenLayers.Map('map', { maxResolution: 1000 }); layer = new OpenLayers.Layer.Image( 'Globe ESA', '[url]', new OpenLayers.Bounds(-180.0, -12333.5, 21755.5, 90.0), new OpenLayers.Size(windowWidth, windowHeight), { numZoomLevels: 100 }); map.addLayer(layer); nav = new OpenLayers.Control.Navigation(); map.addControl(nav); //events test map.events.register('moveend', map, function (e) { alert(e.xy); }); map.zoomToMaxExtent(); } </script> In the examples of openlayer, they don't use the eventargs, but there must be a way to get the zoomlevel, or the x and y after panning, right? Thank you!

• Sheet and thread memory problem

  - by Xident

  Hi Guys, recently I started a project which can export some precalculated Grafix/Audio to files, for after processing. All I was doing is to put a new Window (with progressindicator and an Abort Button) in my main xib and opened it using the following code: [NSApp beginSheet: REC_Sheet modalForWindow: MOTHER_WINDOW modalDelegate: self didEndSelector: nil contextInfo: nil]; NSModalSession session=[NSApp beginModalSessionForWindow:REC_Sheet]; RECISNOTDONE=YES; while (RECISNOTDONE) { if ([NSApp runModalSession:session]!=NSRunContinuesResponse) break; usleep(100); } [NSApp endModalSession:session]; A Background Thread (pthread) was started earlier, to actually perform the work and save all the targas/wave file. Which worked great, but after an amount of time, it turned out that the main thread was not responding anymore and my memory footprint raised unstoppable. I tried to debug it with Instruments, and saw a lot of CFHash etc stuff growing to infinity. By accident i clicked below the sheet, and temporary it helped, the main thread (AppKit ?) was releasing it's stuff, but just for a little time. I can't explain it to me, first of all I thought it was the access from my thread to the Progressbar to update the Progress (intervalled at 0,5sec), so I cut it out. But even if I'm not updating anything and did nothing with the Progressbar, my Application eat up all the Memory, because of not releasing it's "Main-Event" or whatsoever Stuff. Is there any possibility to "drain" this Main thread Memory stuff (Runloop / NSApp call?). And why the heck doesn't the Main thread respond anymore (after this simple task) ??? I don't have a clou anymore, please help ! Thanks in advance ! P.S. How do you guys implement "threaded long task" Stuff and updating your gui ???

• Why can’t I create a database in an empty ASP MVC 2 project using Project->Add->New Item->SQL Server

  - by Dr Dork

  I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error right at the start when trying to add a new database to my fresh, empty ASP MVC 2 project... A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something. This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions... What am I missing/forgetting to do that is causing this error? Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL). Thanks so much in advance for all your help! I'm going to start researching these questions right now.

• How to implement tokenizer.rbegin() and rend() for boost::tokenizer ?

  - by Chan

  Hello everyone, I'm playing around with boost::tokenizer however I realize that it does not support rbegin() and rend(). I would like to ask how can I add these two functions to the existing class? This is from the boost site: #include <iostream> #include <string> #include <boost/tokenizer.hpp> using namespace std; using namespace boost; int main() { string str( "12/12/1986" ); typedef boost::tokenizer<boost::char_separator<char>> tokenizer; boost::char_separator<char> sep( "/" ); tokenizer tokens( str, sep ); cout << *tokens.begin() << endl; // cout << *tokens.rbegin() << endl; How could I implement this? return 0; }

• Calling a method from another view in objective-c. (iphone sdk).

  - by MarcZero

  Hello. I am currently creating a multi-view game on the iPhone platform. I have my main view start to play some background music upon loading. I then go to another view and start the game. I am trying to get the background music from the original view to stop once I start the game. I am having trouble getting the stop playing music message to my original view. Here is the relevant info: The main view where the sound is played from is just a subView of the programViewController class called *viewController. The heading is in the programAppDelegate class. The sound is done using the AVAudioPlayer class and plays fine when the program starts up and when I navigate to other subviews that are added on by going through the menu system. In the view that I want to start the game, I attempt to call the instance of the class to turn of the player but anytime I use this format of code: [viewController #######]; It gives a build error of "viewController undeclared" no matter what I put after the "viewController" in the message.I have attempted to import the programAppDelegate.h file but it still gives the same error. I realize this might be a simple misunderstanding of the objective-c language but I cannot find any info on this issue. I am a recent convert from Java so I am trying to wrap my head around everything. Thank you for your time!

• mailto: anchor links unloading html5 video in Chrome

  - by Robin Pyon

  I have a very simple page with a <video> tag and an email anchor link: http://jsfiddle.net/6GquX/3/ Clicking the email link in Chrome (OS X 10.8 + Win7, 23.0.1271.97) invokes the beforeunloadchange event and causes the video to unload, which isn't the desired outcome. Curiously enough, if I let the video buffer a bit and then click the email link, the video keeps playing and doesn't unload. To my knowledge this only occurs in Chrome and I'm truly at a loss. Visiting any HTML5 video player site (videojs, flowplayer etc), starting a HTML5 video and then immediately simulating an email click with document.location.href = "mailto:[email protected]" in the dev console yields the same error. However, I'm inclined to think it's the way in which the video has been encoded as I'm unable to recreate the above with a video downloaded from YouTube's HTML5 player: http://jsfiddle.net/6GquX/4/ (source) 1. Is it possible that YouTube are encoding their videos in a particular way to combat this? 2. Are there any strategies / hacks I can employ to get around this?

• Absolutely positioned element moved by margin of another element

  - by user1505528

  Here is my jsFiddle for the following question: http://jsfiddle.net/arelia/Rruxf/ I'd like to have a header that stays at the very top of the body and a footer that stays at the very bottom of the body. I have a content div (position: relative) between the header and footer, and when I set a margin around the div my absolutely positioned header and footer move from their top/bottom positions by the height of that margin (this also happened when I tried setting a margin above and below the paragraphs in the div). In the fiddle you can see that the footer is not attached to the bottom even though it's absolutely positioned (I went ahead and made the header static since static gives the intended result). How do I position the header and footer to the top and bottom of the body and not have the content in the middle move those two elements? If the position: absolute elements are moved out of the flow why would anything affect their position at all? I've tried searching here and Google for "CSS margin affects absolute" and a few other phrases to no avail. I discovered this while playing around with it some more in developer tools: Metrics show the body is the height of the html element minus the amount of one margin (the margin that's still affecting the footer). So, the body must be stretching to the height of the content div since there is nothing else within the document flow within the body to define its height. But that height ends where the content ends instead of after the margin. Shouldn't it include the margin? If I make the height of the body 100%, the footer positions itself to the bottom of the viewport and then stays fixed in that spot when I scroll. Why isn't it attaching itself to the bottom of the body instead of the bottom of the viewport?

• My HTML5 web app crashes and I have no clue how to debug

  - by Shouvik

  Hi All, I have written a word game using HTML5 canvas tag and a little bit of audio. I developed the application on the chrome web browser on a linux system. Recently during the testing phase it was tried on safari 5.0.3 on Mac and the webpage froze. Not just the canvas element, but interactive element on the page froze. I have at some times experienced this problem on google chrome when I was developing but since the console did not throw any error before this happened, I did not give it much credence. Now as per requirements I am supposed to support both chrome and safari but this dismal performance on safari has left me shocked and I cannot see what error can be thrown which might lead to such a situation. Worse yet the CPU usage on using this application peaks to 70-80percent on my 2yr old macbook running ubuntu... I can only but pity the person who uses mac to operate this app, which undoubtedly is a heavier OS. Could someone help me out with a place I can start with to find out what exactly is causing this issue. I have run profiles on this webapp on google chromes console and noticed that in the heap spanshot value increases steadily with the playing of the game, specifically (root) value which jumps up by 900 counts. Any help would be very appreciated! Thanks EDIT: I don't know if this helps, but I have noticed that even on refreshing the page after the app becomes unresponsive the page reloads and I am still not able to interact with the page elements but the tab scroll bar continues to work and I can see my application window completely. So to summaries the tab stops accepting any sort of user interaction inside the page. Edit2: Nop. It doesn't work still... The app crashes on double click on the canvas element. The console is not throwing any errors either! =/ I have noticed this problem is isolated only to safari!

• Call AsyncTask methods from another class/service (callbacks?)

  - by TiGer

  Hi, I was wondering if it's possible to call specific methods defined within the AsynTask class from another class and/or service ? In my specific case I have a Service playing some sounds, but the sound is selected from a List with available sounds... When a sounds is selected it is downloaded from my home server, this takes some time (not much, let's say around the 3-4 seconds, the sounds/effects aren't big in size)... So my problem at the moment is that I have a service to play those sounds, and when I select one I wanted to show a progressdialog... The way (if I understood correctly) is to use an AsyncTask, but the only thing the AsyncTask will do is telling my Service to play a specific sound from my server... So there is no "callback" from the service to the Asynctask... How can I achieve that ? How can I call a running AsyncTask, which sits in another class, and tell him all work is done and thus he can stop showing the ProgressDialog ? Or am I over-engineering it and there are other ways ? Thanks in advance...

• Dynamic External Program in debug tab vs2008

  - by Justin Holbrook

  I am playing with NServiceBus using the generic host; specifically I'm working on having 2 different configurations, a debug configuration that logs to the console and a release version that logs to metabase (I'm using VS2008). I had just made some code changes (commented out a logging statement), but it was still showing in the log when I ran my solution. I eventually figured out that I had switched configuration to release, made my change, then built. I think the change isn’t being picked up because in the debug tab of my project properties I have the following (abbreviated) path to the generic host: C:...\Inventory\bin\Debug\NServiceBus.Host.exe Notice it specifically points to the debug directory. So basically even though I’m in release config it’s firing up the host in the debug directory which I think is then using the dll's in the debug directory (which is why my changes didn't get picked up). I tried to come up with a workaround, but have been unsuccessful. VS Macros (like $(Configuration)) and relative pathing are not allowed here. http://connect.microsoft.com/VisualStudio/feedback/details/422223/relative-path-not-allowed-in-c-project-debug-properties-window Any ideas? I hope this doesn’t require a custom build task.

• Convert Markdown text to RTF, using Ruby and Pandoc?

  - by niteshade

  Playing with Ruby and Ruby-Pandoc. Seems like a nice tool, if I can get it to work. I'd like to convert some Markdown text (with embedded lists and other fanciness) to Rich Text. Here's the text I'm converting: Title === This is a paragraph. Hallelujah. Here comes a nested list. --- * List item 1 * List item 1.1 * List item 1.2 * List item 2 * List item 2.1 Here's my Ruby code... require 'pandoc-ruby' input = File.read(test.md) converter = PandocRuby.new(input, from: :markdown, to: :rtf) puts converter.convert ... which (after saving the output to a file) produces a document without anything but a title: Here's the code of the RTF file: {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs36 Title\par} {\pard \ql \f0 \sa180 \li0 \fi0 This is a paragraph. Hallelujah.\par} {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs32 Here comes a nested list.\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2.1\sa180\par} In addition, even if it did show up in my RTF viewer (Mac TextEdit), the RTF code seems to have lost all list nesting. I don't know how to diagnose this, whether I have not stated necessary header information or something in Ruby-Pandoc. Thanks in advance!

• Mysql dropping inserts with triggers

  - by user2891127

  Using mysql 5.5. I have two tables. One has a whitelist of hashes. When I insert a new row into the other table, I want to first compare the hash in the insert statement to the whitelist. If it's in the whitelist, I don't want to do the insert (less data to plow through later). The inserts are generated from another program and are text files with sql statements. I've been playing with triggers, and almost have it working: BEGIN IF (select count(md5hash) from whitelist where md5hash=new.md5hash) 0 THEN SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'Already Whitelisted'; END IF; END But there's a problem. The Signal throwing up the error stops the import. I want to skip that line, not stop the whole import. Some searching didn't find any way to silently skip the import. My next idea was to create a duplicate table definition, and redirect the insert to that dup table. But the old and new don't seem to apply to table names. Other then adding an ignore column to my table then doing a mass drop based on that column after the import, is there any way to achieve my goal?

• Generic file container for quick read of data

  - by DreamCodeR

  Since there are some major privacy issues with alot of social networking sites I am trying to think about alternatives. One is to let the user keep all the information stored in some kind of file container. Now, I haven't found a single type of container that can hold "generic" information. Only for audio/video. What I want is a container that can be read by PHP with some kind of index file that lists up the users pictures in a image/ directory in the container, FOAF files (or some alternative XML-file describing users information and friends, etc.). My thoughts was to let the user keep all their information and data stored in a container that can be imported/exported and deleted from my server (the prototype social networking site I am trying to create), and then uploaded to another site that might use the same format (not that I think that will ever happen, but the user still keeps all their pictures, data, comments, messages, etc). The only thing I have come up with yet is to create a tar archive with the Archive_tar library which extracts and creates Tar-archives with an index-file describing which files are holding the messages (there might be several so each file won't be so large), what pictures are in the image/ folder and what are their names and what comments they have gotten etc. Maybe also the permissions for viewing each type of content. Does there exist any generic file format of a container that I can use to keep all this information in one file with a tree-like index file? Or must i try and create something like this myself?

• Why can't I display same object in multiple viewports?

  - by user288973

  Hi, I'm pretty new to OpenGL. Was playing around with some code but can't figure out why the following will not produce two viewports with the same object view. Heres the code: glViewport(0, windowHeight/2, windowWidth/2, windowHeight); glScissor(0, windowHeight/2, windowWidth/2, windowHeight); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective( 45.0, (GLfloat)(windowWidth/2)/(GLfloat)(windowHeight/2), 0.1f, 500.0 ); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT); drawParticleView(); glViewport(windowWidth/2, 0, windowWidth, windowHeight/2); glScissor(windowWidth/2, 0, windowWidth, windowHeight/2); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective( 45.0, (GLfloat)(windowWidth/2)/(GLfloat)(windowHeight/2), 0.1f, 500.0 ); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT); drawParticleView(); drawParticleView() just draws an array of rectangles. The problem is that the second viewport is a squashed representation of the first. My window width is 1280 and height 960. I'm obviously doing something wrong but what? Thanks

• Composable FLinq expressions

  - by Daniel

  When doing linq-to-sql in c#, you could do something like this: var data = context.MyTable.Where(x => x.Parameter > 10); var q1 = data.Take(10); var q2 = data.Take(3); q1.ToArray(); q2.ToArray(); This would generate 2 separate SQL queries, one with TOP 10, and the other with TOP 3. In playing around with Flinq, I see that: let data = query <@ seq { for i in context.MyTable do if x.Parameter > 10 then yield i } @> data |> Seq.take 10 |> Seq.toList data |> Seq.take 3 |> Seq.toList is not doing the same thing. Here it seems to do one full query, and then do the "take" calls on the client side. An alternative that I see used is: let q1 = query <@ for i in context.MyTable do if x.Param > 10 then yield i } |> Seq.take 10 @> let q2 = query <@ for i in context.MyTable do if x.Param > 10 then yield i } |> Seq.take 3 @> These 2 generate the SQL with the appropriate TOP N filter. My problem with this is that it doesn't seem composable. I'm basically having to duplicate the "where" clause, and potentially would have to duplicate other other subqueries that I might want to run on a base query. Is there a way to have F# give me something more composable? (I originally posted this question to hubfs, where I have gotten a few answers, dealing with the fact that C# performs the query transformation "at the end", i.e. when the data is needed, where F# is doing that transformation eagerly.)

• Weird send() problem (with Wireshark log)

  - by Meta

  I had another question about this issue, but I didn't ask properly, so here I go again! I'm sending a file by sending it in chunks. Right now, I'm playing around with different numbers for the size of that chunk, to see what size is the most efficient. When testing on the localhost, any chunk size seems to work fine. But when I tested it over the network, it seems like the maximum chunk size is 8191 bytes. If I try anything higher, the transfer becomes extremely, painfully, slow. To show what happens, here are the first 100 lines of Wireshark logs when I use a chunk size of 8191 bytes, and when I use a chunk size of 8192 bytes: (the sender is 192.168.0.102, and the receiver is 192.168.0.100) 8191: http://pastebin.com/E7jFFY4p 8192: http://pastebin.com/9P2rYa1p Notice how in the 8192 log, on line 33, the receiver takes a long time to ACK the data. This happens again on line 103 and line 132. I believe this delay is the root of the problem. Note that I have not modified the SO_SNDBUF option nor the TCP_NODELAY option. So my question is, why am I getting delayed ACKs when sending files in chunks of 8192 bytes, when everything works fine when using chunks of 8191 bytes? Edit: As an experiment, I tried to do the file transfer in the other direction (from 192.168.0.100 to 192.168.0.102), and surprisingly, any number worked! (Although numbers around 8000 seemed to perform the smoothest). So then the problem is with my computer! But I'm really not sure what to check for. Edit 2: Here is the pseudocode I use to send and receive data.

• Calculations on the iteration count in for loop in Ruby 1.8.7

  - by user1805035

  I was playing around with Ruby and Latex to create a color coding set. I'm more than a novice with C++, but haven't looked at Ruby until now. So, still learning a lot of coding. I have the following block of code below. When attempting to run this, band1 = 1e+02. I've tried band1 = (BigDecimal(i) * 100).to_f thinking maybe there was some odd floating point issue. This is just me trying anything though as an integer multiplied by an integer should create an integer, if I'm still thinking correctly. I've tried a variety of other things as well (things that I can do in C++, but this ain't C++), but to no avail. (1..9).each do |i| #Band 1 (0..9).each do |j| #Band 2 (0..11).each do |k| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = i*100 band2 = j band3 = $mult[k] end end end Not sure what I'm missing. Should I be using .each_with_index through these iterations? I've tried this: (1..9).each_with_index {|i, indexi| #Band 1 (0..9).each_with_index {|j, indexj| #Band 2 (0..11).each_with_index {|k, indexk| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = indexk * 100 and I get the same answer. I can't see why 1*100 should equate to such a large number? Thank you, AT

• Game design flaw, need help investigating

  - by Snake

  I am not sure if I will be able to get help here but I would give it a shot. The problem is I dont know where the problem is. I have a cards game, in which when you "human" play by dragging a card, then at the end of card being dragged, a handler using postExecute is called with delay of 0.5 sec to start the next player in turn (which is a bot) The bot chooses the color and plays it and at the end of the animation (the card moving to the middle) a handler is started for the next bot and so on. Once the play reaches again to the human player, it waits for his touchs to drag the crad and start the cycle again. The problem that in production, sometimes I am getting errors. The error is resulting in somehow messing up the sequence which ends up with players having more cards than others. After investigation, I found that the transition from human to bot is the problem. Somehow, the transition is happening twice (meaning handler calling post execute twice and the bot is playing twice and everything is messed up). Its been mutliple months and I can't reproduce it (to fix it) and I cna't figure out why this is happeneing? ANY IDEA how I can go after it? How can I get more info about or how can I solve something like that? any pointer would help me

• How many hours a day (of the standard 8) do you actually work? [closed]

  - by someone

  Possible Duplicate: How much do you [really] work a day When I started working (not so long ago), I was very conscientious about really working. If I didn't work for 10 minutes at a time, I felt like I was cheating. But as I started to look around me, I realized that I was the only one... and most of my coworkers were spending a big percentage of their time browsing the internet or playing solitaire. I started to slack off a little more than usual... while still basically getting all my work done. But while I do all that's required of me, and usually quickly, I no longer beg for work to fill up my spare time; I'm content to do what I'm told and play around when no one makes sure I'm busy enough. Which means that I'm often bored and underutilized. (Which I was even when I begged for work - people are pretty laid back about the workload and don't seem to realize how much I can get done if pushed to the fullest.) But I was just talking to a friend who graduated with me and also recently started working... and she came to me with the same concerns about slacking. She's working remotely, which means there are often gaps in communication when she can't really get anything done... And she's feeling guilty about it. Which made me rethink the whole thing... So, as workers, how many hours, out of the 8 standard average, are you actually working (honestly)? And, as bosses, how many hours do you expect your workers to work? And from an ethical standpoint, how much free time, or space out time, can workers have during the day without being considered to be "cheating" their office of labor and money?

• How to make Finder 'Open With' work for my application (XCode, OS X)?

  - by Adion

  I have created an application that is capable of playing audio files. This in itself works fine, and so does drag&drop from finder to my application. What I would like as well, is that people can use my application from Finder using the Open With menu (or even allow them to set my application as default for a certain file type) After a lot of searching, I found that I should configure a document type in XCode (Editing information property lists) I successfully added such a type named 'Music File', with UTI 'public.mp3' When I now right-click an MP3 file, my application is listed in the 'Open With' menu. Trying to use it, my app opens, but I get a warning message saying "The document could not be opened. App cannot open files in the 'Music File' format" It doesn't appear to be passed through the command line as is the case in Windows. My application does support drag&drop from Finder, and this is working fine too. I don't really know where to look next, so it would be great if anyone could point me in the right direction. My application isn't using NSDocument, so the 'Class' field doesn't apply for me I think (and according to the docs this field isn't required, but it doesn't say how to handle it without a Class)
