• Website Live Chat Script - Interface With Windows Live Messenger?

  - by Sootah

  Hello again fellow StackOverflow users! What I am looking for currently is your opinions on the what the best live chat script would be for my website. I'd be using this on both my local computer repair (which I've not really set up yet) company's site, as well as my other technical support site that is geared more towards showing people how to fix whatever problem they have themselves. It'll be a little bit before I launch it on either site, as I need to find a good design for my local computer repair company's site, as well as redesign TweaksForGeeks.com's layout so that it's more magazine like. (If you have any suggestions on good Wordpress templates for these, that'd also be swell. :) ) Features I'd like for the live chat script to have: (if possible) Real-time posting of messages (or as close to real time as possible) Integration into my Windows Live Messenger account - By this I mean it'd be handy if instead of me having to man a separate open browser window and constantly check it for new messages, it'd be much more convenient if it would instead just allow me to receive and respond to messages via my Windows Live account the same way I'd chat with any other person on my contact list. Sound notification of new messages when the chat isn't the focused window - In the event that using Windows Messenger isn't possible then I'd need it to notify me upon receipt of a new message. Recording of chat transcripts - This is a MUST HAVE Easy customization - I'll likely want to modify how it looks and whatnot, in addition to the fact that I'm going to set it up so that the chat transcripts can be posted to my site easily in order to be useful to my other visitors later on. With all that in mind, what is available out there? I've not really researched this at all yet; aside from doing a cursory search just before I decided to ask my StackOverflow brothers. As always, thank you! -Sootah

• how to play an audio soundclip when a nib is loaded - welcome screen - xcode

  - by Pavan

  I would like to do the following two things: 1) I would like to play an audio file qhen a nib is loaded 2) After that i would like to switch views when the audio file has finished playing. This will be easy as i just need to call the event that initiates the change of view by using the delegate method -(void) audioPlayerDidFinishPlaying{ //code to change view } I dont know how to to play the audio file when a nib is loaded. Using the AVFoundation framework, I tried doing the following after setting up the audio player and the variables associated with it in the appropriate places i wrote the following: - (void)viewDidLoad { [super viewDidLoad]; NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: @"sound" ofType: @"mp3"]; NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error:nil]; [fileURL release]; self.player = newPlayer; [newPlayer release]; [player prepareToPlay]; [player setDelegate: self]; [player play]; } Although this does not play the file as the viewdidload method gets called before the nib is shown so the audio is never played or heard. What do i need to do so that i can play the audio file AFTER the nib has loaded and is shown on the screen? can someone please help me as ive been working on this for 3 hours now. Thanks in advance.

• Reduce unwanted noise

  - by Rajeev

  In the below code sometimes when microphone is not connected some noise is generated and the system just keeps on buzzing the same sound.Whats wrong with the code below and how to reduce the unwanted noise. Should i set myMic.setLoopBack(false) in the below code <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="300" height="100" creationComplete="init()"> <mx:Script> <![CDATA[ import mx.controls.Alert; import flash.net.NetStream; private var myMic:Microphone; private var recordingState:String = "idle"; private function init():void { myMic = Microphone.getMicrophone(); myMic.setSilenceLevel(0); myMic.rate = 44; myMic.gain = 100; myMic.setUseEchoSuppression(true); micLevel.visible = true; //Security.showSettings(SecurityPanel.MICROPHONE); myMic.setLoopBack(true); if (myMic != null) { myMic.setUseEchoSuppression(true); micLevel.setProgress(myMic.activityLevel, 100); addEventListener(Event.ENTER_FRAME, showMicLevel); //micLevel.setProgress(myMic.activityLevel, 100); } } private function showMicLevel(event:Event):void{ switch (recordingState){ case "idle" : micLevel.setProgress(myMic.activityLevel, 100); break; } } ]]> </mx:Script> <mx:ProgressBar x="0" y="36" mode="manual" id="micLevel" label="" labelPlacement="bottom" width="100" fontSize="10" fontWeight="normal"/> </mx:Application>

• What would it take to get auto-revert-mode to actually work in my dired buffer?

  - by Cheeso

  Apparently auto-revert-mode is supposed to work in dired buffers. I had never heard of this, but the doc says it works. Then I read a little more and found some fine print: Auto-reverting Dired buffers currently works on GNU or Unix style operating systems. It may not work satisfactorily on some other systems. ...and... [dired buffers] do not auto-revert when information about a particular file changes (e.g. when the size changes) or when inserted subdirectories change. To be sure that all listed information is up to date, you have to manually revert using g, even if auto-reverting is enabled in the Dired buffer. source Well, uh, gee.... That doesn't sound like autorevert to me. What would it take to get auto-revert for dired to actually work? Even on (gasp) non-Unix operating systems. Could I just modify auto-revert-handler to call revert-buffer on dired buffers?

• VB6 Game Development

  - by CVS-2600Hertz-wordpress-com

  Hi All, I am developing a game in VB6 (plz don't ask me why :) ). The storyboard is ready and a rough implementation is underway. I am following a "pure-software-rendering" approach. (i.e. no DirectX, no openGL etc.) Amongst many others, the following "serious" problems exist: 2D alpha transparency reqd. to implement overlays. Parallax implementation to give depth-of-field illusion. Capturing mouse-scroll events globally (as in FPS-es; mapping them to changing weapon). Async sound play with absolute "near-zero-lag". Any ideas anyone. Please suggest any well documented library/ocx or sample-code. Plz do suggest solutions with good performance and as little overhead as possible. Also, anyone who has developed any games, and would be open to sharing her/his code would be highly appreciated. (any well-acknowledged VB games whose source-code i can study??) UPDATE: Here is a screen shot of GearHead Garage. This picture ought to describe what i was attempting in words above... :) Thank You

• Show users a list of unique items on Java Google App Engine

  - by James

  I've been going round in circles with what must be a very simple challenge but I want to do it the most efficient way from the start. So, I've watched Brett Slatkin's Google IO videos (2008 & 2009) about building scalable apps including http://www.youtube.com/watch?v=AgaL6NGpkB8 and read the docs but as a n00b, I'm still not sure. I'm trying to build an app on GAEJ similar to the original 'hotornot' where a user is presented with an item which they rate. Once they rate it, they are presented with another one which they haven't seen before. My question is this; is it most efficient to do a query up front to grab x items (say 100) and put them in a list (stored in memcache?) or is it better to simply make a query for a new item after each rating. To keep track of the items a user has seen, I'm planning to keep those items' keys in a list property of the user's entity. Does that sound sensible? I've really got myself confused about this so any help would be much appreciated.

• Setting White balance and Exposure mode for iphone camera + enum default

  - by Spectravideo328

  I am using the back camera of an iphone4 and doing the standard and lengthy process of creating an AVCaptureSession and adding to it an AVCaptureDevice. Before attaching the AvCaptureDeviceInput of that camera to the session, I am testing my understanding of white balance and exposure, so I am trying this: [self.theCaptureDevice lockForConfiguration:nil]; [self.theCaptureDevice setWhiteBalanceMode:AVCaptureWhiteBalanceModeLocked]; [self.theCaptureDevice setExposureMode:AVCaptureExposureModeContinuousAutoExposure]; [self.theCaptureDevice unlockForConfiguration]; 1- Given that the various options for white balance mode are in an enum, I would have thought that the default is always zero since the enum Typedef variable was never assigned a value. I am finding out, if I breakpoint and po the values in the debugger, that the default white balance mode is actually set to 2. Unfortunately, the header files of AVCaptureDevice does not say what the default are for the different camera setting. 2- This might sound silly, but can I assume that once I stop the app, that all settings for whitebalance, exposure mode, will go back to their default. So that if I start another app right after, the camera device is not somehow stuck on those "hardware settings".

• Are these settings correct for sending mail through Rails/Gmail?

  - by aressidi

  Hi there, I spend a good deal of time building an email system for my Rails app that uses Gmail to send bulk mail to a list of opt-in users. I realize a shortcomming of using Google Apps for my mail, namely a rate limit on the number of emails it will send out (i believe 500). Anyway, I have reached out to my users to see how many have received the email, and a lot of them have not, though some have. The list I tried sending to was about 540 users, so I would have expected more "yes, got it," then "nope, still waiting" responses. I have two questions: Do these settings look correct for outgoing bulk mailing through Gmail? Again, using google apps to manage my domain and i know some people (including myself) have received the mailer. This is in a mail.rb initializer in my app. ActionMailer::Base.delivery_method = :sendmail ActionMailer::Base.smtp_settings = { :address => "smtp.gmail.com", :port => 25, :domain => "mydomain.com", :authentication => :login, :user_name => "[email protected]", :password => "mypass" } Is there any way I can test if the mail was delivered, or at least attempted to be delivered? I can't tell where in the list the mailer stops mailing! The way I generate the list is through a query which then passes the user info to a mailer worker which sends the emails out via Starling/Workling. Any advice here would be useful. Happy to post code, but want to make sure the method I'm using is sound. Thanks for the help!

• OpenAL not playing on Max OS X 10.6

  - by Grimless

  I've been working on getting a basic audio engine running on my Mac using OpenAL. It seems relatively straightforward after working with OpenGL for a while. However, despite the fact that I believe I have everything in place, my sound will not play. Here is the order of things I am doing: //Creating a new device ALCdevice* device = alcOpenDevice(NULL); //Create a new context with the device ALCcontext* context = alcCreateContext(device, NULL); //Make that context current alcMakeContextCurrent(context); //Do lots of loading stuff to bring in an AIFF... voodooAIFF = myAIFFLoader("name"); //Then use that data ALuint buf; alGenBuffers(1, &buf); //Check for errors, but none happen... //Bind buffer data. alBufferData(buf, voodooAIFF.format, voodooAIFF.data, voodooAIFF.sizeInBytes, voodooAIFF.frequency); //Check for errors, none here either... //Create Source ALuint src; alGenSources(1, &src); //Error check again, no errors. //Bind source to buffer alSourcei(src, AL_BUFFER, buf); //Set reference distance alSourcei(sourceID, AL_REFERENCE_DISTANCE, 1); //Set source attributes including gain and pitch to 1 (direction set to 0,0,0) //Check for errors, nothing... //Set up listener attributes. //Check for errors, no errors. //Begin playing. alSourcePlay(src); Observe silence... Any insight, what steps am I missing here?

• Multiple websites, Single sign-on design

  - by Yannis

  Hi all, I have a question. A client I have been doing some work recently has a range of websites with different login mechanisms. He is looking to slowly migrate to a single sign-on mechanism for his websites (all written in asp.net mvc). I am looking at my options here, so here is a list of requirements: 1) It has to be secure (duh) 2) It needs to support extra user properties over and above the usual name, address stuff (such as money or credits for a user) 3) It has to provide a centralized user management web console for his convenience (I understand that this will be a small project on top of whatever design solution I choose to go for) 4) It has to integrate with the existing websites without re-engineering the whole product (I understand that this depends on the current product implementation). 5) It has to deal with emailing the user when he registers (in order for him to activate his account) 6) It has to deal with activating the user when he clicks the activate me link in the email (I understand that 5 and 6 require some form of email templating system to support different emails per application) I was thinking of creating a library working together with forms authentication that exposes whatever methods are required (e.g. login, logout, activate, etc. and a small restful service to implement activation from email, registration processing etc. Taking into account that loads of things have been left out to make this question brief and to the point, does this sound like a good design? But this looks like a very common problem so arent there any existing projects that I could use? Thanks for reading.

• Work for huge company or small company that makes products for huge company?

  - by TheGambler

  I'm facing a career decision. I currently work for a huge, huge, huge company (this should bring 3-4 companies to mind) as a programmer. I work on a really big (3 million lines of code) J2EE web application. I've been out of college for 2 years and I pretty much know that big corporate life isn't for me. There is a career opportunity to work for a small company that has a lot of funding and huge potential to sell their main project to this huge company I work for.This company makes kiosk software and works with a nearby kiosk software company. The deal isn't done, but I would come straight in to work on this project. This would be more of a interactive media position and I would do the development in flash/action script. I personally think this will be more interesting work then what I do now. This company does have other clients right now, just not on the scale of this potential huge client. I was told that my initial salary would be equal to what I'm making now, but if we land this client it could go up a lot more. I have a wife and child which should and will play a part in my decision if I should take this job. We do though have family that if crap hit the fan we could live with until we got back on our feet. So with the information provided, does this sound like a good opportunity and should I take it? This is a huge decision and the reason I'm asking the question here is because there are a lot of people here that have probably faced this decision before.

• GitHub solution for personal repo

  - by Luke Maurer

  So I've got my private SVN repo on my home server, and it has maybe 30 different modules thrown together in it, ranging from abortive throw-away larks to a few endeavors that might actually go somewhere someday. But a recent filesystem failure (BTW, never ever EVER use XFS without a battery-backed hardware RAID) has me spooked and thinking of using a DVCS for all that. I've also just had quite the swig of the Git koolaid, and I've been working with GitHub of late, so that's where I'm looking right now. Of course, it would be silly to shell out major cash for a separate private Git repo for every little project, and I don't want to have to be selective about what I throw up there (I love all my children :-D ), so I'll have to be somewhat creative about this. I can happily use SSH to my home box to use Git the way I've been using SVN, and I'm thinking from there I could amalgamate everything into, say, a big project with 30 submodules, which I then push to GitHub. What'd be a sane way to set this up? Does using submodules sound feasible? How do I sync it all to my private GitHub repo? Cron job? Git hook? I'd love to hear it if anyone's done something similar. I'm not really married to Git or GitHub, so a sufficiently compelling feature of another solution might sway me. But if your answer does involve a different system (especially a different VCS), be advised it'll be a tougher sell :-)

• Dynamic loading of shared objects using dlopen()

  - by Andy

  Hi, I'm working on a plain X11 app. By default, my app only requires libX11.so and the standard gcc C and math libs. My app has also support for extensions like Xfixes and Xrender and the ALSA sound system. But this feature shall be made optional, i.e. if Xfixes/Xrender/ALSA is installed on the host system, my app will offer extended functionality. If Xfixes or Xrender or ALSA is not there, my app will still run but some functionality will not be available. To achieve this behaviour, I'm not linking dynamically against -lXfixes, -lXrender and -lasound. Instead, I'm opening these libraries manually using dlopen(). By doing it this way, I can be sure that my app won't fail in case one of these optional components is not present. Now to my question: What library names should I use when calling dlopen()? I've seen that these differ from distro to distro. For example, on openSUSE 11, they're named the following: libXfixes.so libXrender.so libasound.so On Ubuntu, however, the names have a version number attached, like this: libXfixes.so.3 libXrender.so.1 libasound.so.2 So trying to open "libXfixes.so" would fail on Ubuntu, although the lib is obviously there. It just has a version number attached. So how should my app handle this? Should I let my app scan /usr/lib/ first manually to see which libs we have and then choose an appropriate one? Or does anyone have a better idea? Thanks guys, Andy

• How to generate XML from an Excel VBA macro?

  - by SuperNES

  So, I've got a bunch of content that was delivered to us in the form of Excel spreadsheets. I need to take that content and push it into another system. The other system takes its input from an XML file. I could do all of this by hand (and trust me, management has no problem making me do that!), but I'm hoping there's an easy way to write an Excel macro that would generate the XML I need instead. This seems like a better solution to me, as this is a job that will need to be repeated regularly (we'll be getting a LOT of content in Excel sheets) and it just makes sense to have a batch tool that does it for us. However, I've never experimented with generating XML from Excel spreadsheets before. I have a little VBA knowledge but I'm a newbie to XML. I guess my problem in Googling this is that I don't even know what to Google for. Can anyone give me a little direction to get me started? Does my idea sound like the right way to approach this problem, or am I overlooking something obvious? Thanks StackOverflow!

• Moving information between databases

  - by williamjones

  I'm on Postgres, and have two databases on the same machine, and I'd like to move some data from database Source to database Dest. Database Source: Table User has a primary key Table Comments has a primary key Table UserComments is a join table with two foreign keys for User and Comments Dest looks just like Source in structure, but already has information in User and Comments tables that needs to be retained. I'm thinking I'll probably have to do this in a few steps. Step 1, I would dump Source using the Postgres Copy command. Step 2, In Dest I would add a temporary second_key column to both User and Comments, and a new SecondUserComments join table. Step 3, I would import the dumped file into Dest using Copy again, with the keys input into the second_key columns. Step 4, I would add rows to UserComments in Dest based on the contents of SecondUserComments, only using the real primary keys this time. Could this be done with a SQL command or would I need a script? Step 5, delete the SecondUserComments table and remove the second_key columns. Does this sound like the best way to do this, or is there a better way I'm overlooking?

• Midiplayer stops playing sounds after 16 notes.

  - by user349673

  Hi. I am currently programming a Piano Keyboard editor, much like the one you can find in Cubase, Logic, Reason etc.. I have this big grid, double array new int [13][9], which makes it 13 rows, 9 columns. The first column [0-12][0] is the Keyboard, at the top there's "high C" (midi note 72) and at the bottom there's "low C" (midi note 60). That column is an array of JButtons and when you press for example "low C", note 60 is being played by the Synthesizer. I've gotten this to work pretty OK as for now, but one problem I have is that I can only play 16 notes in a row, then it's like the Synthesizer shuts down or something. Do you guys have ANY idea of what the problem is? A bit of the code: import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; import javax.sound.midi.*; actionPerformed(ActionEvent ae){ for(int i = 0; i<13; i++){ if(o== instr[i]){//instr is the button array SpelaTangent(i); } } } public void SpelaTangent(int tangent){ int [] klaviatur = new int[13]; for(int i = 0; i<13; i++){ klaviatur[i] = (72-i); } try { Synthesizer synth = MidiSystem.getSynthesizer(); synth.open(); final MidiChannel[] mc = synth.getChannels(); Instrument[] instrument = synth.getDefaultSoundbank().getInstruments(); synth.loadInstrument(instrument[1]); mc[0].noteOn(klaviatur[tangent],350); mc[0].noteOff(klaviatur[tangent],350); } catch (MidiUnavailableException e) {} } Help is very much appreciated!

• calculate camera up vector after glulookat()?

  - by carrots

  I'm just starting out teaching myself openGL and now adding openAL to the mix. I have some planets scattered around in 3D space and when I touch the screen, I'm assigning a sound to a random planet and then slowly and smoothly flying the "camera" over to look at it and listen to it. The animation/tweening part is working perfectly, but the openAL piece isn't quiet right. I move the camera around by doing a tiny translate() and gluLookAt() for every frame to keep things smooth (tweening the camera position and lookAt coords). The trouble seems to be with the stereo image I'm getting out of the headphones.. it seems like the left/right/up/down is mixed up sometimes after the camera rolls or spins. I am pretty sure the trouble is here: ALfloat listenerPos[]={camera->currentX,camera->currentY,camera->currentZ}; ALfloat listenerOri[]={camera->currentLookX, camera->currentLookY, camera->currentLookZ, 0.0,//Camera Up X <--- here 0.1,//Camera Up Y <--- here 0.0}//Camera Up Z <--- and here alListenerfv(AL_POSITION,listenerPos); alListenerfv(AL_ORIENTATION,listenerOri); I'm thinking I need to recompute the UP vector for the camera after each gluLookAt() to straighten out the audio positioning problem.. but after hours of googling and experimenting I'm stuck in math that suddenly got way over my head. 1) Am I right that I need to recalculate the up vector after each gluLookAt() i do? 2) If so, can someone please walk me though figuring out how to do that?

• Technology and language for a stable Digital Audio Workstation development

  - by Kill KRT

  Hi, I'm designing a cross platform (Windows/Linux/OS X) application, something like a digital audio workstation. I'd like to create a software where users have a fully featured sequencer (multiple tracks with automation) and where it is possible to create instruments using a visual language (as Pure Data/Max MSP). Ehm... I know that I've already posted a question about a related issue... But in order to decide which technology I should use, I think I'd better to make more investigation. I'm a quite experted user of audio trackers (Renoise, Protracker,...) and sequencers (FL Studio, Cubase 5), but I didn't ever try to develop even a basic audio tracker. I know just the basic theory of mixing sound and know how basically a DSP works. My questions are: Where I can find a good tutorial/guide/book about this issue? Do you think using C# (with NAudio) could dramatically reduce performance? I know C++ would be the best choice, but I find C# so elegant and easy to build and port, while C++ is so powerful and fast, but there are too #define and bad things for my taste! ;-) Thank you.

• REST API - why use PUT DELETE POST GET?

  - by Andre

  So -i was looking through some articles on creating REST API's. And some of them suggest using all types of HTTP requests: like PUT DELETE POST GET. So - we would create for example index.php and write API this way: $method = $_SERVER['REQUEST_METHOD']; $request = split("/", substr(@$_SERVER['PATH_INFO'], 1)); switch ($method) { case 'PUT': ....some put action.... break; case 'POST': ....some post action.... break; case 'GET': ....some get action.... break; case 'DELETE': ....some delete action.... break; } Ok - granted - I don't know much baout web services (yet). But - wouldn't it be easier to just accept JSON object through normal $_POST and then respond in JSON as well. We can easily serialize/deserialize via php's json_encode and json_decode and do whatever we want with that data without having to deal with different HTTP request methods... Am I missing something? UPDATE 1: Ok - after digging through various API's and learning a lot about XML-RPC, JSON-RPC, SOAP, REST I came to a conclusion that this type of API is sound. Actually stack exchange is pretty much using this approach on their sites and I do think that these people know what they are doing Stack Exchange API.

• Code smells galore. Can this be a good company?

  - by Paperflyer

  I am currently doing some contract work for a company. Now they want to hire me for real. I have been reading on SO about code smells lately. The thing is, I have worked with some of their code and it smells. Badly. They use incredibly old versions of MSVC (2003), they do not seem to use version control systems, most code is completely undocumented, variable names with more than three letters are a rarity, there is commented out code all over the place, some methods take huge amounts of arguments, UI design is seemingly done by blind people... Yet they seem to be quite successful with what they do and their actual algorithms seem to be pretty sound and rather sophisticated. Since they mostly do DSP stuff, I am willing to ignore the UI side of things, but really these code smells are worrying. What would you think of a company that doesn't seem to value readable code? The people are nice enough and payment would be good. How much would you value code smells in this context? You see, this is my first job and SO got me worried, so I turn to you for suggestions ;-)

• Custom permalinks switching function. Please check this logic...

  - by Scott B

  I've got a setting in my theme options panel to allow the user to switch the permalinks setting to support friendly URLs. I'm only allowing /%postname%/ and /%postname%.html as options. I don't want to be triggering an htaccess rewrite everytime someone accesses a page on the site or views theme options, so I'm trying to code this to avoid that. I've got an input field in theme options that's called $myTheme_permalinks. The default value for this is "/%postname%/" but the user can also change it to "/%postname%.html" Here's the code at the top of theme options to handle this setting. Does this look sound? if(get_option('myTheme_permalinks') =="/%postname%/" && get_option('permalink_structure') !== "/%postname%/" || !get_option('myTheme_permalinks')) { require_once(ABSPATH . '/wp-admin/includes/misc.php'); require_once(ABSPATH . '/wp-admin/includes/file.php'); global $wp_rewrite; $wp_rewrite->set_permalink_structure('/%postname%/'); $wp_rewrite->flush_rules(); update_option('permalink_structure','/%postname%/'); update_option('myTheme_permalinks','/%postname%/'); } else if (get_option('myTheme_permalinks') =="/%postname%.html" && get_option('permalink_structure') !== "/%postname%.html" && ) { require_once(ABSPATH .

• Google app engine: Poor Performance with JDO + Datastore

  - by Bosh

  I have a simple data model that includes USERS: store basic information (key, name, phone # etc) RELATIONS: describe, e.g. a friendship between two users (supplying a relationship_type + two user keys) I'm getting very poor performance, for instance, if I try to print the first names of all of a user's friends. Say the user has 500 friends: I can fetch the list of friend user_ids very easily in a single query. But then, to pull out first names, I have to do 500 back-and-forth trips to the Datastore, each of which seems to take on the order of 30 ms. If this were SQL, I'd just do a JOIN and get the answer out fast. I understand there are rudimentary facilities for performing joins across un-owned relations in a relaxed implementation of JDO (as described at http://gae-java-persistence.blogspot.com) but they sound experimental and non-standard (e.g. my code won't work in any other JDO implementation). Is this really my best bet? Otherwise, how do people extract satisfactory performance from JDO/Datastore in this kind of (very common) situation? -Bosh

• LNK 1104 error to lib file - Continues despite removing includes and links

  - by user1556594

  A link error to a lib file popped up out of the blue in a c++ application of mine after code was working fine in my last session. Error 1 error LNK1104: cannot open file '..........\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\lib\fmodex_vc.lib' I triple checked my project directories were set up correctly to link to the lib file, that the file existed in said directory and that it was a working version of the .lib. My next step was to remove the includes to the file and the links to bypass the error and work on the rest of my code until the problem was solved. The error remains, however, despite: Commenting out absolutely every include relating to the lib. Commenting out absolutely every line of code dependant on the includes. Removing the directory from VC++ Directories in the project properties. Checking the Additional Library Directories field was also clear of references. To my understanding this should have made the library and related code virtually non-existant to the compiler. What am I missing? The library itself is fmodex_vc.lib - part of the FMOD API for providing sound to interactive applications. Again, the application was working one session, but failed to compile the next. I hadn't touched the code since so this led me to believe some aspect of VS is at fault. I'd like to avoid the time involded in re-installing if possible as I'm on the clock for a review tomorrow evening and there are a few more things I'd like to smooth out before then. If necessary, however, I won't hesitate. Very much appreciate the help.

• Experience with Take home Programming Test for Interviews

  - by Alan

  Okay this is not "programming" related per-se, but it is a situation that I believe the SO audience would be more familiar with, than say an ask.yahoo.com audience, so please forgive me. I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

• Career day in kindergarten

  - by Péter Török

  I was invited to the kindergarten group of my elder daughter to talk and answer the kids' questions about my profession. There are 26 kids of age 4-6 in the group, plus 3 teachers who are fairly scared of anything related to programming and IT themselves, but bold enough to learn new tricks. I would have about 20-30 minutes, without projector or anything. They have an old computer though, which by its look may be a 486, and I am not even sure if it's functioning. My research turned up excellent earlier threads, with lots of good tips: How would you explain your job to a 5-year old? Career Day: how do I make “computer programmer” sound cool to 8 year olds? What things can I teach a group of children about programming in one day? My situation is different from each of the above though: the latter ones are concerned with older children, while the first one is about talking to a single kid (or elder person)—a group of 20 is a whole different challenge. How can I teach the kids and their teachers about programming in a fun way?
