i new android , looking write app measuring decibel sound level . idea when sound reaches level user gets alert. that's it. can me out this. can using html5/javascript ? appreciated. taken android media player decibel reading for native android/java based decibel calculation mediarecorder: mrecorder = new mediarecorder(); mrecorder.setaudiosource(mediarecorder.audiosource.mic); mrecorder.setoutputformat(mediarecorder.outputformat.three_gpp); mrecorder.setaudioencoder(mediarecorder.audioencoder.amr_nb); mrecorder.setoutputfile("/dev/null"); mrecorder.prepare(); mrecorder.start(); public double getamplitude() { if (mrecorder != null) return (mrecorder.getmaxamplitude()); else return 0; } to calculate db value : powerdb = 20 * log10(getamplitude() / referenceamp); reference: http://en.wikipedia.org/wiki/decibel#field_quantities not sure if in html5 on android

i have mvc site uses telerik grid control. when use scriptregistrar include desired .js files, works fine , files includes are: telerik.common.min.js telerik.textbox.min.js telerik.calendar.min.js telerik.datepicker.min.js telerik.grid.min.js telerik.grid.filtering.min.js however, if include these same files using <script type="text/javascript" src="/scripts/telerik.common.min.js"></script> ....*all others*.... and totally take out scriptregistrar (i want because want use mvc4 bundling support instead) grid not load correctly. the reason of problem scriptregisterar add jquery scripts page startup action. think have 2 work-arounds : 1st: you can add "telerik.common.min.js" file through scriptregisterar , add other telerik script files through mvc 4 bundling component. if so, telerik tries load related script files @ run time. example if have combobox in page, telerik add scripts load script after page load. ignores loa

it's strange same picture display different on pc/mac/ios device. this url of picture: http://imgtest.meiliworks.com/pic/d/b3/0d/1a6157b2828bbcbfadb0d4d114b0_600_2400.jpg it's 77x310 in safari on mac osx 10.7, it's 310x77 in safari on ipad! if download picture , open directly, it's become 310x77. what's wrong picture? your image contains exif orientation tag value of 6 (rotated 90 degrees left). not image viewers handle tag properly. don't respect it, they'll display image rotated 90 degrees right.

i have been trying query images on sd card through mediastore content provider , display thumbnail on gridview. however, if load image thumbnail on main thread, scrolling gets incredibly slow... so tried load bitmap through asynctasks: scrolling performance got better, grid items keep reloading thumbnail until gets correct bitmap... here asynctask, loads bitmaps: package x.y; import java.lang.ref.weakreference; import android.content.contentresolver; import android.graphics.bitmap; import android.graphics.bitmapfactory.options; import android.os.asynctask; import android.provider.mediastore; import android.widget.imageview; public class imagethumbnailloader extends asynctask<long, void, bitmap> { private final options moptions; private weakreference<imageview> mimageviewweakreference; private contentresolver mcontentresolver; public imagethumbnailloader(imageview imageview, contentresolver cr) { mcontentresolver

i'm loading class dynamically in php. file , class name gotten out of database. file must contain class , method. tried solve interface, don't how beautiful way. what suggestions? use class_exists() determine if class has been defined, method_exists() determine if class has method , instanceof determine if class implements interface.

i have rails app acting oauth 2.0 provider (using oauth2-provider gem). stores information related users (accounts, personal information, , roles). there 2 client apps both authenticate through app. client apps can use client_credentials grant type find users email , other things don't require authorization code. users can log in client apps using password grant type. now issue we're facing users' roles defined globally on resource host. if user given admin role on resource host, user admin on both clients. question is: should have more fine-grained access control? i.e. user can editor app1 not app2 . i guess easy way change role names so: app1-admin , app2-admin , app1-editor , app2-editor , etc. bigger question is: implementing whole system correctly; is, should storing info on resource host, or should denormalize data onto client apps? a denormalized architecture this: user data on resource host, localized user data on each client host. user@example.com

how write function returns incrementing numbers on each call? print counter() # 0 print counter() # 1 print counter() # 2 print counter() # 3 etc for clarity, i'm not looking generator (although answer use it). function should return integer, not iterable object. i'm not looking solution involving global or otherwise shared variables (classes, function attribute etc). see here http://www.valuedlessons.com/2008/01/monads-in-python-with-nice-syntax.html useful insights matter. in short, from itertools import count counter = lambda c=count(): next(c)

with php dom, getting trs , tds inside. <?php foreach($table->getelementsbytagname('tr') $tr){ echo $tr->getelementsbytagname('td')->item(0)->nodevalue); } ?> can exclude first tr , tds. i think node list numerically indexed (though cannot test it), using key in foreach may work: foreach($table->getelementsbytagname('tr') $key => $tr){ // don't act on first element if ($key > 0) { echo $tr->getelementsbytagname('td')->item(0)->nodevalue); } }

i have picturebox lots of transparent png's drawn into... now i'd save content of picturebox file, without transparency. how can this? i have tried remove transparency image this, didn't work, still got transparent image after save. ... removetransparency(picturebox.image).save(savefiledialog.filename); private bitmap removetransparency(image transparentimage) { bitmap src = new bitmap(transparentimage); bitmap newimage = new bitmap(src.size.width, src.size.height); graphics g = graphics.fromimage(newimage); g.drawrectangle(new pen(new solidbrush(color.white)), 0, 0, newimage.width, newimage.height); g.drawimage(src, 0, 0); return newimage; } you may cycle through pixel (please not using getpixel/setpixel) change color or may create bitmap same size, create graphics context image, clear image favorite background color , draw image on (so transparent pixels replaced background color). example did this? public static bitma

i'm new semantic web. i'm trying sample application can query data different data sources in 1 query. have created small rdf file contains references dbpedia resources defining localities. question : how can data contained in file , other information in description of distant resource (for example : name of person local file, , total poulation in city dbpedia-owl:populationtotal distant rdf file). don't understand sparql query language, tried use jena arq api service keyword doesn't solve problem. please? i guess looking semantic web client library , tries leverage ggg. albeit, standard exploration algorithm of framework follows rdfs:seealso links. nevertheless, general approach seems looking for, i.e., create local graph consists of seed graph , traverse relations level, e.g., 3 steps, resolves uris , load content local triple. utilising advanced technologies sparql federation might later ;)

i've been using apc while optcode cache , memcached object caching. i'm thinking of switching apc hophop. however, seems hiphop hasn't had development lately. recommend using hophop on apc or stick apc? thanks! personally, i'd stick apc. hiphop kind of optimization and, i've ready, pain in ass code working with. doesn't seamlessly take have , convert it. it's understanding there's php can't used it.

i trying hands on mvc 2, ado.net ef , poco. have generated entity classes in separate library using poco generator.these poco entities used viewpages (not sure if that's right way design or need separate viewmodels classes ?) now, if take case of simple scenario need add employee object( related department master), should recommended way transfer these objects between layers. layered structure of application : i have thought of various alternatives: i have method in employee controller named addemployee() accepts formcollection parameter. within form collection posted data such employee name, age , salary etc , id of selected department . 1.) 1 way can create dto employeedepartment dto used map values formcollection is. can break them @ manager layer , use them create entity objects i.e employee object , refer department query similar this: e.department = department.where(i => i.deptid == empdepdto.dept_id).first() i not big fan of , feel every time there

is there way can rid of "sftp" labels tabs? it's taking tons of horizontal space , serves me no purpose. use project , link ftp :)

from experience in industry found many companies avoid using relational databases , ado.net interact database. instead use flat databases , write sql statement directly against database ,, since believe having many tables linked using foreign keys , using ado.net interact db have serious performance drawbacks on large application have millions of transaction per day.,, these points valid? no, these point not valid (in scenarios). relational databases faster in large datasets because of relations. (unless of course have huge list of non-relational data , frankly, datasets not relational in huge application these days?) stackoverflow.net example gets 7 million page views day , built on relational database. also, please see answer more. similar discussion: database vs. flat files edit: huge mean millions of transactions per day.... :) edit: removed ef reference.

i'm using flash builder 4.6 , in 1 of actionscript projects, have referenced .swc library file. the way added project > properties > flex library build path > library path tab > add swc... here popup occurs , must select .swc file browsing through machine , selecting one. once that, it'll display added library this: somelibrary.swc - /full/path/to/the/swc/here/lib/somelibrary.swc what want able use relative path instead, like: somelibrary.swc - ../../lib/somelibrary.swc does know way or workaround able use relative paths swc libraries in flash builder? thanks! i suggest dump mxmlc compilator's settings xml file (where can add required swcs , paths hands using favorite text editor). add compilator option -dump-config=build.xml find xml config, modify needs replace -dump-config=build.xml -load-config=build.xml

i've got object encapsulates remote calls. needs credentials make calls. think credentials should passed constructor that, once object created, user doesn't have keep passing them in every time make call object. seems sensible factoring. if though i've got added complexity of clients use object needing passed factory instead of object because credentials won't known until run time. given work, wondering if credentials (being string values , no code) count dependency or not? does question make sense? see i've gotten head after using ioc being passed constructor counts dependency , should instance of implementation of interface. i wouldn't see strings dependencies. instead, create iusercontext or iusercredentials abstraction can inject.

there multiple subclasses of classloader: bootstrapclassloader,extclassloader,appclassloader , on. however, think 1 bootstrapclassloader enough! can please tell me why there many different kinds of classloaders? notice: why there many kinds of classloaders, not why there many instances of classloader! each class loader designed load classes different locations. instance, can create class loader load class file networked server or download binary of class remote web server, etc. logic performs operation baked class loader , provides consistent interface clients can load classes regardless of how class loader performs loading. bootstrapclassloader capable of loading classes jvm_home/lib directory...but if need load them different location?? in short, because there infinite (well, not quite) number of ways load classes , there needs flexible system allow developers load them want.
