• Audio Panning using RtAudio

  - by user1801724

  I use Rtaudio library. I would like to implement an audio program where I can control the panning (e.g. shifting the sound from the left channel to the right channel). In my specific case, I use a duplex mode (you can find an example here: duplex mode). It means that I link the microphone input to the speaker output. I seek on the web, but I did not find anything useful. Should I apply a filter on the output buffer? What kind of filter? Can anyone help me? Thanks

• What tasks should be explicitly mentioned in a job reference? [closed]

  - by Martin

  Glossary A job reference (see also the german version) is a letter from the (former) employer that states what the employee did, and how well he did it. There are oh so weird rules here on how to phrase stuff therein, but this is not what this question is about. Question I hope this can even be generally answered, but even if country/region specific, I think there is enough international know-how on this site to get useful answers for different regions. I was wondering how detailed the tasks a programmer / developer did should be spelled out in a job reference. (After all, they can be spelled out in all detail in a CV when applying for a new job.) So how much detail is usual for a job reference? Example Developed Windows applications in C++ or Developed Windows Desktop Applications using C++ with MS Visual Studio 2005 and MFC, utilising Boost 1.47 and specif library xyz, focusing on subsystem abc for numerical calculations of ... etc. What makes more sense?

• What is the best Video Conference integrated solution for Us? [closed]

  - by Andrei B

  we are trying to integrate a simple Video Conferencing (open source) solution into our existing application which is written in C++ and it runs on Linux. I am currently looking at using Ekiga (formely known as GnomeMeeting) or Homer Conferencing (short: Homer). My plan is to "integrate" an existing Video Conferencing client into our existing software. Please give me recommendation on which 3rd party application or library to use to add video conferencing feature to our application. PS: Please don't close this question. I asked it on StackOverflow and it got closed, so where am I supposed to ask this question? If not here, then whats the point of asking lol.

• Learning Asynchronous programming

  - by xenoterracide

  Asynchronous non-blocking event driven programming seems to be all the rage. I have a basic conceptual understanding of what this all means. However what I'm not sure is when and where my code can benefit from being asynchronous, or how to make blocking IO, non-blocking. I'm sure that I can simply use a library to do this, but I'm more interested in more in depth concepts, and the various ways to implement it myself. Are there any comprehensive/definitive books, or other resources on this subject (like GoF for Design Patterns, or K&R for C, tldp for things like bash)? (Note: I'm not sure if this is actually functionally an identical question to my question on Learning event driven programming)

• Direct3d - Code structure

  - by marcg11

  I'm learning directx in a master's degree and they taught us to have a GraphicsLayer class which is the one connecting with the direct3d library. That way this class is completly independent from the other classes (my game classes), meaning changing the renderer to OpenGL wouldn't require much effort but only changing the graphicLayer. This classe has it's LoadAssets, Paint methods, but I have a question, they told us to load all the assets inside this class. This means all these methods will be in the loadAssets method: D3DXCreateTextureFromFileEx(g_pD3DDevice,"tiles.png",0,0,1,0,D3DFMT_UNKNOWN,D3DPOOL_DEFAULT,D3DX_FILTER_NONE,D3DX_FILTER_NONE,NULL,NULL,NULL,&texTiles); // And more resources to load //... texTiles as you see is a LPDIRECT3DTEXTURE9 instance which is declared in the graphicLayer.h. So my question is, how do you manage all the resources? Do I have to declare in the .h all my game textures even if I'm not using them? How would you load only those resources there are in a scene and draw them in a code-strucured way?

• Are there any good music mixers available, equivalent to Windows "MP3 Tunes"?

  - by RobinJ

  In Windows my dad used to have a program called MP3 Tunes. I have tried running it with Wine, and it worked. But strange things kept happening to the program, so it's not a reliable way to play music. Basically I just want to have 2 players (in a single window) with these features: Preloading tracks in a player without immediately starting them. Fading from one track to the other. A timer on each player. These features are also desired, but not required: Microphone input. Prelistening before loading a song in a player (through a seperate sound card). Pitch/Tempo control. Just being able to browse folders in the filesystem (without things like a music library). Here are some screenshots of the program to clarify what I'm looking for:

• How fast does a language get outdated?

  - by Dummy Derp

  I started learning Java recently. I started learning it using books that I picked up from the library, some that I bought, and here and there from Java documentation. The book that I use for Java was published in the year 2011. In 2012, Java8 will be released followed by Java9 in the year 2013. The questions are: How do I keep myself updated about developments in Java without having to buy a tome for Java8 and/or Java9 Is a book published in 2008 an outdated book for studying JSP and Servelets? I'm talking about Head First Servlets and JSP

• Using my own code in freelance projects.

  - by Witchunter

  I have been into freelance business for more than 2 years. While doing projects for other people, I've build a compilation of common tasks that I implement in projects and put them into code. It's kind of a library with some functions that I can reuse without having to rewrite the same thing dozen times. I'm talking about accessing Access databases, downloading information from FTP and similar stuff. Is this acceptable from a legal point of view? What's the difference in reusing the old code and rewriting it from the scratch (using you own brain again, therefore the exact same logic)? I do not hold any copyright to it, of course, and provide the source code for these classes to my clients.

• Is extensive documentation a code smell?

  - by Griffin

  Every library, open-source project, and SDK/API I've ever come across has come packaged with a (usually large) documentation file, and this seems contradictory to the wide-spread belief that good code needs little to no comments. What separates documentation from this programming methodology? a one to two page overview of a package seems reasonable, but elegant code combined with standard intelisense should have theoretically deprecated the practice of documentation by now IMO. I feel like companies only create detailed documentation and tutorials because its what they've always done. Why should developers have to constantly be searching through online documentation in order to learn how to do things when such information should be intrinsic to the classes, methods and namespaces?

• Using <= for every dependency in case of following semantic versioning idea

  - by zerkms

  As Semantic Versioning (and common sense) declares - the major version is incremented in case if non backward compatible change is introduced. Now let's assume we have a project called Project that has a current version 1.0.42 and a library Lib it depends on that is of a 2.1.3 version at the moment. Does that mean that following semver ideology we should constraint the dependency of the Project to be Depends: Lib (< 3)? From my experience - no one does that, but I find it semantically correct and very self-descriptive. What do you think of this?

• How could there still not be a mysqldb module for Python 3?

  - by itsadok

  This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

• Best tool for monitoring backups, etc. and trending statstics from that data

  - by Randy Syring

  I have done some research on nagios, opennms, and zenoss but am not confident that I have found what I am looking for. The main driving force for me right now is being able to monitor backups. This includes mysql, mssql, and eventually some file system backups. We have a tool that wraps the backup process for these different systems and collects statistics. So, items like: number of databases backed up size of db backup file size of db backup file compressed time to make backup time to zip file I want to be able to A) have notifications if the jobs are not run according to schedule B) be able to set thresholds on the statistics which would trigger notifications C) I want to be able to trend and graph the statistics I am planning on sending this information to the monitoring application through an HTTP POST. Or, the monitoring application could pull it from a log file as well. However, we will have other processes with other "arbitrary" (from the monitoring system's perspective) statics that will want to monitor and trend, so flexibility is very important. The tool or tools should also be able to do general monitoring and trending of network interfaces, server load, etc. Once we get the backup monitoring in place, we will want to include those items as well. Thanks.

• Parallel Computing in .Net 4.0

  - by kaleidoscope

  Technorati Tags: Ram,Parallel Computing in .Net 4.0 Parallel computing is the simultaneous use of multiple compute resources to solve a computational problem: To be run using multiple CPUs A problem is broken into discrete parts that can be solved concurrently Each part is further broken down to a series of instructions Instructions from each part execute simultaneously on different CPUs Parallel Extensions in .NET 4.0 provides a set of libraries and tools to achieve the above mentioned objectives. This supports two paradigms of parallel computing Data Parallelism – This refers to dividing the data across multiple processors for parallel execution.e.g we are processing an array of 1000 elements we can distribute the data between two processors say 500 each. This is supported by the Parallel LINQ (PLINQ) in .NET 4.0 Task Parallelism – This breaks down the program into multiple tasks which can be parallelized and are executed on different processors. This is supported by Task Parallel Library (TPL) in .NET 4.0 A high level view is shown below:

• Installing old Loki games on 12.04 64-bit results in no audio

  - by FlabbergastedPickle

  All, Here's an interesting problem. I followed instructions provided online for installing Loki Games' Heroes of Might and Magic 3 (see http://www.swanson.ukfsn.org/loki/ and http://wtanaka.com/node/7641) and got it installed and patched to the latest version. However, every time I start it regardless whether the pulseaudio is running, I get the following error: LD_LIBRARY_PATH=/usr/local/lib/Loki_Compat/ /usr/local/lib/Loki_Compat/ld-linux.so.2 /usr/local/games/Heroes3/heroes3.dynamic ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default Couldn't open audio: My first soundcard is HDMI output and my second one is the actual soundcard (HP DM1 running 12.04 64-bit with latest updates). I did set up /etc/asound.conf as follows: asound.conf pcm.!default { type hw card 1 } ctl.!default { type hw card 1 } So, the default soundcard should work ok. Between Shadowgrounds that also stopped working and this it appears a there may be some unfinished business/regressions in 32-bit support on 64-bit systems in 12.04. Any thoughts?

• Translate extrinsic rotations to intrinsic rotations ( Euler angles )

  - by MineMan287

  The problem I have is very frustrating: I am using the Jitter Physics library which gives Quaternion rotations, you can extract the extrinsic rotations but I need intrinsic rotations to rotate in OpenTK (There are other reasons as well so I don't want to make OpenTK use a Matrix) GL.Rotate(xr, 1, 0, 0) GL.Rotate(yr, 0, 1, 0) GL.Rotate(zr, 0, 0, 1) EDIT : Response to the first answer Like This? GL.Rotate(zr, 0, 0, 1) GL.Rotate(yr, 0, 1, 0) GL.Rotate(xr, 1, 0, 0) Or This? GL.Rotate(xr, 1, 0, 0) GL.Rotate(yr, 0, 1, 0) GL.Rotate(zr, 0, 0, 1) GL.Rotate(zr, 0, 0, 1) GL.Rotate(yr, 0, 1, 0) GL.Rotate(xr, 1, 0, 0) GL.Rotate(xr, 1, 0, 0) GL.Rotate(yr, 0, 1, 0) GL.Rotate(zr, 0, 0, 1) I'm confused, please give an example

• Webshop for digital goods with voucher / gift card system [duplicate]

  - by Kelzama

  This question already has an answer here: Which Ecommerce Script Should I Use? 1 answer I'm searching for a webshop which provides the following: The shop offers digital goods (like mp3) User can buy a voucher / gift card @Reseller (Or there is a code provided in the CD) User can enter his code @ webshop and gets the download (unregistered) User can enter his code @ webshop and download is added to his/her library (registered) optional: Resellers can buy codes from the Webshop I already tried prestashop as it looks quite nice. But it needs a lot of custom programming (and has a very strange voucher-system). Customer has to add the File into the basket and add the voucher at checkout. I want to skip that ;) Is there a Webshop (Or CMS + Plugin) which provides the things I need? (it could also be a CMS with a Storage/Folder Plugin (like joomla + K2) and a possibility to activate downloads via unique Codes.) Any ideas are highly appreciated :) Thanks in advance.

• Animation file format

  - by Paul

  I'm trying to make a simple 2D animation file format. It'll be very rudimentary: only an XML file containing some parameters (such as frame duration) and metadata, and some images, each representing a frame. I'd like to have the whole animation (frames and XML document) packed in a single file. How do you suggest I do that? What libraries are there that would allow easy access to the files inside the animation file itself? The language I'm using is C++ and the platform is Windows, but I'd rather not use a platform dependent library, if possible.

• Detailed C++ book for a programmer already familiar with C and object-oriented programming?

  - by Anto

  I know (to some extent) a few languages, including C, Java and Python. I'm also (somewhat) familiar with Scala and Scheme, plus I can read (but not write) x86 Assembly. Say I want to learn C++, what is a good book which doesn't try to teach me what a class is, teach me inheritance, polymorphism or loosely coupled classes again, nor does try to teach me other basics, just the C++ language (as well as how to write idiomatic C++ code, not e.g. Java with C++ syntax) and its standard library? Note: "Detailed" as used in the title means that it doesn't try to cover C++ in 100 pages, I want to know the details of the language. Of course, mastery comes from practice, but I don't want to learn just a little bit of C++ from the book, but learn it quite thoroughly.

• PHP crashing during oAuth scripts

  - by FunkyChicken

  I just installed Nginx 1.2.4 and PHP 5.4.0 (from svn) (php fpm). CentOs 5.8 64 The problem I have is that PHP crashes the moment I run any social oAuth scripts. I have tried to log into Facebook, Twitter and Google with various scripts that I know work on my other servers. When I load the scripts I get a 502 error from Nginx. And I find these errors in the log: in php-fpm log: WARNING: [pool www] child 23821 exited on signal 11 (SIGSEGV) after 1132.862984 seconds from start in nginx log: ERROR: recv() failed (104: Connection reset by peer) while reading response header from upstream From what I can see, it goes wrong when PHP tries to make a request to any of the oAuth servers. https://github.com/mahmudahsan/PHP-SDK-3.0---Graph-API-base-Facebook-Connect-Tutorial-Source for example is one of the scripts that works perfectly on my other machines, but causes PHP to crash. I found: http://stackoverflow.com/questions/3616191/nginx-php-fpm-502-bad-gateway which seems to be a similar problem, but I cannot find a way to solve it. +++ UPDATE +++ Now I have been doing some debugging in 1 of the scripts that is playing up. If you go to line 808 http://pastebin.com/gSnzRtXb it runs the curl_exec() command. When that is ran, it crashes. If i echo'test';exit; just above that line, it echo's correctly, if i do it below that line, php crashes. Which means it's that line 808 which causes the crash. So I made a very simple script to do some testing: http://pastebin.com/Rshnyhcm which also uses curl_exec, but that runs just fine. So I started to dig deeper into that query from the facebook script to see what values the $opts array contains from line 806. Output of that array is: http://pastebin.com/Cq9ffd3R What the problem is, I still have no clue :(

• What type of encoding can I use to make a string shorter?

  - by Abe Miessler

  I am interested in encoding a string I have and I am curious if there is a type of encoding that can be used that will only include alpha and numeric characters and would preferably shorten the number of characters needed to represent the string. So far I have looked at using Base64 encoding to do this but it appears to make my string longer and sometimes includes == which I would like to avoid. Example: test name|120101 becomes dGVzdCBuYW1lfDEyMDEwMQ== which goes from 16 to 24 characters and includes non-alphanumeric. Does anyone know of a different type of encoding that I could use that will achieve my requirements? Bonus points if it's either built into the .NET framework or there exists a third party library that will do the encoding.
