  • iPhone SDK: How to record voices with ambient noise supression?

    - by Harkonian
    Can anyone point me in the right direction on how I would minimize ambient noise while recording someone speaking using the iPhone SDK Core Audio? I'm guessing a band-pass filter that eliminates any frequencies above and below the human vocal range might work. I have no idea how I would implement band filters on audio in the SDK though. The optimum solution would be one that eliminates the noise from the stream before it is written to memory/disk. Some sample code would be appreciated.

  • Signal processing or algorithmic programming for a PLC

    - by james singen smythe
    I have an application that takes voltages and temperatures as analog inputs and does some processing using an algorithm which involves signal processing such as low-pass filtering, exponential smoothing, and other steps which might typically be done in a high-level programming language such as C or C++. I'm curious how I could perform these same steps using a PLC, and in particular, the Allen-Bradley Control-Logix system? It seems to me that the instruction set with ladder logic is too limited for this. Could I perform this using structured text?

  • Simple wordpress Registration

    - by andrew
    I am looking for a wordpress plugin which simplifies the registration process by allowing users to sign up on the spot without having to be sent an email? It would be good if you could also pass a redirect_to parameter in the url like you can for the login. Note:Some thoughtless person migrated this question over to super user where it was closed. I believe this question fits the criteria allowable for stack overflow.

  • JqTouch - Detect trigger for animation

    - by majman
    Yet another problem I'm having w/ jqTouch... I'm trying to detect what element was clicked to trigger an animation so that I can pass parameters from the clicked item to the subsequent page. My HTML is: <div id="places"> <div class="toolbar"> <h1>Places</h1> <a class="back" href="#">Back</a> </div> <ul> <li id="1"><a href="#singleplace">Place 1</a></li> <li id="2"><a href="#singleplace">Place 2</a></li> <li id="3"><a href="#singleplace">Place 3</a></li> </ul> </div> <div id="singleplace"> <div class="toolbar"> <h1></h1> <a class="back" href="#">Back</a> </div> </div> When I click on any of the list items in #places, I'm able to slide over to #singleplace just fine, but I'm trying to detect which element was clicked so that I can pass parameters into the #singleplace div. My javascript is: var placeID; $('#places a').live('mouseup',function(){ $('#singleplace h1').html($(this).text()) placeID = $(this).parent().attr('id'); }) I've tried several alternatives to the $(el).live('event', fn()) approach including: $('#places a').live('click',fn()... $('#places a').live('mouseup',fn()... $('#places a').live('tap',fn()... $('#places a').tap(fn()... None of which seem to work. Is there a better way I could be handling this? I noticed on jqTouch's issues page, there is this: http://code.google.com/p/jqtouch/issues/detail?id=91 which may be part of the problem...

  • Adding an HTTP Header to the request in a servlet filter

    - by Mason
    I'm integrating with an existing servlet that pulls some properties out of the HTTP header. Basically, I'm implementing an interface that doesn't have access to the actual request, it just has access to a map of k-v for the HTTP headers. I need to pass in a request parameter. The plan is to use a servlet filter to go from parameter to header value but of course the HttpServletRequest object doesn't have an addHeader() method. Any ideas?

  • Where is the central ZFS website now?

    - by Stefan Lasiewski
    Oracle dumped OpenSolaris in Fall 2010, and it is unclear if Oracle will continue to publicly release updates to ZFS, except maybe after they release their next major version of Solaris. FreeBSD now has ZFS v28 available for testing. But where did v28 come from? I notice that the main ZFS website does not show version 28 available. Has this website been abandoned? If so, where is the central website for the ZFS project, so that I can browse the repo, read the mailing lists, read the release notes, etc. (I realize that OpenSolaris has been dumped by Oracle, and that they are limiting their ZFS releases to the community).

  • Monitors - inches vs resolution

    - by Vnuk
    I'm currently moving away from living five years only on laptop to a desktop setup. I'm currently browsing for monitors and I've noticed something strange. On my laptop I have 1920x1200 on 17". To get the same resolution on a monitor I have to get Dell U2410 24" or Samsung SM2443NW 24". I do not need (or want) 7" more inches of screen, I just want the 1920x1200 resolution. Why is this setup (big resolution on less inches of screen) available on a laptop but not on a regular monitor? I'm setting this as a community wiki beacuse I think that there is no right answer here...

    I'm getting a compiler error for this line: Collections.sort(terms, new QuerySorter_TFmaxIDF(myInteger)); My customized Comparator is pretty basic; here's the signature and constructor: public class QuerySorter_TFmaxIDF implements Comparator<Term>{ private int numberOfDocs; QuerySorter_TFmaxIDF(int n){ super(); numberOfDocs = n; } } Is there an error because I'm passing an argument into the Comparator? I need to pass an argument...

  • PHP: Is mysql_real_escape_string sufficient for cleaning user input?

    - by Thomas
    Is mysql_real_escape_string sufficient for cleaning user input in most situations? ::EDIT:: I'm thinking mostly in terms of preventing SQL injection but I ultimately want to know if I can trust user data after I apply mysql_real_escape_string or if I should take extra measures to clean the data before I pass it around the application and databases. I see where cleaning for HTML chars is important but I wouldn't consider it necessary for trusting user input. T

  • Migrate reports from MS Access to OOo Base

    - by John Gardeniers
    I'm currently looking at upgrading our office machines from Office XP to Office 2010. For most users the standard edition is fine but just a few of us use Access. There are only a couple of standalone Access databases but the program is used fairly extensively (mostly by myself) as a front end to MySQL. As the cost different between standard and pro versions of Office 2010 is about $170 (AUD) I'm looking at possible alternatives to Access. I'm no huge fan of Open Office but could be convinced to use it if I can find a way to migrate the many reports we currently have in Access. The data is not a problem. So far I've found nothing to suggest this is even possible/practical but perhaps someone here knows otherwise. I'm also open to suggestions for other alternatives to Access but it must be able to produce flexible reports easily. That is the one real strength of Access in my view. Because of its subjective nature I'm making this community wiki.
