  • Wordpress Iphone App: nsxmlparsererrordomain error 64

    - by iMayne
    Spending hours fixing my function.php page and all seemed well, except Im getting errors on my rss feed at: blog.xternalit.co.uk. I leave that issue to rest and installed wordpress iphone app. The connection to my blog works perfect with wordpress' default theme. Ha! But it keeps making me resetting my password. So hell with that. Switched back to my theme and I cant connect from app to blog.

  • opening a fancybox from a drop down box and passing the selected value to it directly

    - by andy
    <select name="mySelectboxsituation_found" id="mySelectboxsituation_found"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> < a href="#" class="incidenttype" name="all" onClick="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"/>CLICK HERE < / a> function cleanUp(){ var subsituation_found1 = $("#fancybox- frame").contents().find('input:radio[name=incident_subcate]:checked').val(); } $(".incidenttype").fancybox({ 'width' : 900, 'height' : 600, 'autoScale': false, 'transitionIn': 'none', 'transitionOut': 'none', 'type': 'iframe', 'onCleanup': cleanUp ); }); clicking on "CLICK HERE" opens the fancybox and transfers the value selected in the drop down box. What I would like to do is open the fancy box when i change the value in the dropdown box...without having to click on the click here link.....i know it is posisble using something like _this....but i am not sure and am looking for some direction... ideally some thing like this ... <select name="mySelectboxsituation_found" id="mySelectboxsituation_found" onChange="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> does any have an idea how to do it.... I have also tried... function test_fan() { alert(document.getElementById('mySelectboxsituation_found').options[document.getElementById('mySelectboxsituation_found').selectedIndex].value); var dropval =document.getElementById('mySelectboxsituation_found').options[document.getElementById('mySelectboxsituation_found').selectedIndex].value; return dropval; } $(document).ready(function(){ $("#autostart").fancybox({ 'onStart':test_fan, 'width': 800, 'height': 700, 'type': 'iframe', href:'main_situation_found.php?incident_maincateid='+document.getElementById('mySelectboxsituation_found').options[document.getElementById('mySelectboxsituation_found').selectedIndex].value }); <a href="#" id="autostart" style="display:none"></a> <form><select id="mySelectboxsituation_found" onchange="$('#autostart').trigger('click');"> <option value="">select</option> <option value="100">option 1</option> <option value="200">trigger</option> <option value="300">option 3</option> <option value="400">option 4</option> </select> </form> the really funny that happens there is that .... on the alert id do get the value i selected so if i selected alert fancybox window 100 100 nothing shows up empty 200 200 100 300 300 200 400 400 300 the fancybox seems to me the the previously selected values and i am not sure why that is happening... thanks andy

  • Modern alternatives to Java

    - by Ralph
    I have been a Java developer for 14 years and have written an enterprise-level (~500 kloc) Swing application that uses most of the standard library APIs. Recently, I have become disappointed with the progress that the language has made to "modernize" itself, and am looking for an alternative for ongoing development. I have considered moving to the .NET platform, but I have issues with using something the only runs well in Windows (I know about Mono, but that is still far behind Microsoft). I also plan on buying a new Macbook Pro as soon as Apple releases their new rumored Arrandale-based machines and want to develop in an environment that will feel "at home" in Unix/Linux. I have considered using Python or Ruby, but the standard Java library is arguably the largest of any modern language. In JVM-based languages, I looked at Groovy, but am disappointed with its performance. Rumor has it that with the soon-to-be released JDK7, with its InvokeDynamic instruction, this will improve, but I don't know how much. Groovy is also not truly a functional language, although it provides closures and some of the "functional" features on collections. It does not embrace immutability. I have narrowed my search down to two JVM-based alternatives: Scala and Clojure. Each has its strengths and weaknesses. I am looking for opinions. I am not an expert at either of these languages; I have read 2 1/2 books on Scala and am currently reading Stu Halloway's book on Clojure. Scala is strongly statically typed. I know the dynamic language folks claim that static typing is a crutch for not doing unit testing, but it does provide a mechanism for compile-time location of a whole class of errors. Scala is more concise than Java, but not as much as Clojure. Scala's inter-operation with Java seems to be better than Clojure's, in that most Java operations are easier to do in Scala than in Clojure. For example, I can find no way in Clojure to create a non-static initialization block in a class derived from a Java superclass. For example, I like the Apache commons CLI library for command line argument parsing. In Java and Scala, I can create a new Options object and add Option items to it in an initialization block as follows (Java code): final Options options = new Options() { { addOption(new Option("?", "help", false, "Show this usage information"); // other options } }; I can't figure out how to the same thing in Clojure (except by using (doit...)), although that may reflect my lack of knowledge of the language. Clojure's collections are optimized for immutability. They rarely require copy-on-write semantics. I don't know if Scala's immutable collections are implemented using similar algorithms, but Rich Hickey (Clojure's inventor) goes out of his way to explain how that language's data structures are efficient. Clojure was designed from the beginning for concurrency (as was Scala) and with modern multi-core processors, concurrency takes on more importance, but I occasionally need to write simple non-concurrent utilities, and Scala code probably runs a little faster for these applications since it discourages, but does not prohibit, "simple" mutability. One could argue that one-off utilities do not have to be super-fast, but sometimes they do tasks that take hours or days to complete. I know that there is no right answer to this "question", but I thought I would open it up for discussion. Are there other JVM-based languages that can be used for enterprise level development?

  • client-side validation in custom validation attribute - asp.net mvc 4

    - by Giorgos Manoltzas
    I have followed some articles and tutorials over the internet in order to create a custom validation attribute that also supports client-side validation in an asp.net mvc 4 website. This is what i have until now: RequiredIfAttribute.cs [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] //Added public class RequiredIfAttribute : ValidationAttribute, IClientValidatable { private readonly string condition; private string propertyName; //Added public RequiredIfAttribute(string condition) { this.condition = condition; this.propertyName = propertyName; //Added } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { PropertyInfo propertyInfo = validationContext.ObjectType.GetProperty(this.propertyName); //Added Delegate conditionFunction = CreateExpression(validationContext.ObjectType, _condition); bool conditionMet = (bool)conditionFunction.DynamicInvoke(validationContext.ObjectInstance); if (conditionMet) { if (value == null) { return new ValidationResult(FormatErrorMessage(null)); } } return ValidationResult.Success; } private Delegate CreateExpression(Type objectType, string expression) { LambdaExpression lambdaExpression = System.Linq.Dynamic.DynamicExpression.ParseLambda(objectType, typeof(bool), expression); //Added Delegate function = lambdaExpression.Compile(); return function; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var modelClientValidationRule = new ModelClientValidationRule { ValidationType = "requiredif", ErrorMessage = ErrorMessage //Added }; modelClientValidationRule.ValidationParameters.Add("param", this.propertyName); //Added return new List<ModelClientValidationRule> { modelClientValidationRule }; } } Then i applied this attribute in a property of a class like this [RequiredIf("InAppPurchase == true", "InAppPurchase", ErrorMessage = "Please enter an in app purchase promotional price")] //Added "InAppPurchase" public string InAppPurchasePromotionalPrice { get; set; } public bool InAppPurchase { get; set; } So what i want to do is display an error message that field InAppPurchasePromotionalPrice is required when InAppPurchase field is true (that means checked in the form). The following is the relevant code form the view: <div class="control-group"> <label class="control-label" for="InAppPurchase">Does your app include In App Purchase?</label> <div class="controls"> @Html.CheckBoxFor(o => o.InAppPurchase) @Html.LabelFor(o => o.InAppPurchase, "Yes") </div> </div> <div class="control-group" id="InAppPurchasePromotionalPriceDiv" @(Model.InAppPurchase == true ? Html.Raw("style='display: block;'") : Html.Raw("style='display: none;'"))> <label class="control-label" for="InAppPurchasePromotionalPrice">App Friday Promotional Price for In App Purchase: </label> <div class="controls"> @Html.TextBoxFor(o => o.InAppPurchasePromotionalPrice, new { title = "This should be at the lowest price tier of free or $.99, just for your App Friday date." }) <span class="help-inline"> @Html.ValidationMessageFor(o => o.InAppPurchasePromotionalPrice) </span> </div> </div> This code works perfectly but when i submit the form a full post is requested on the server in order to display the message. So i created JavaScript code to enable client-side validation: requiredif.js (function ($) { $.validator.addMethod('requiredif', function (value, element, params) { /*var inAppPurchase = $('#InAppPurchase').is(':checked'); if (inAppPurchase) { return true; } return false;*/ var isChecked = $(param).is(':checked'); if (isChecked) { return false; } return true; }, ''); $.validator.unobtrusive.adapters.add('requiredif', ['param'], function (options) { options.rules["requiredif"] = '#' + options.params.param; options.messages['requiredif'] = options.message; }); })(jQuery); This is the proposed way in msdn and tutorials i have found Of course i have also inserted the needed scripts in the form: jquery.unobtrusive-ajax.min.js jquery.validate.min.js jquery.validate.unobtrusive.min.js requiredif.js BUT...client side validation still does not work. So could you please help me find what am i missing? Thanks in advance.

  • Slow Javascript touch events on Android

    - by oneself
    I'm trying to write a simple html based drawing application (standalone simplified code attached bellow). I've tested this on the following devices: iPad 1 and 2: Works great ASUS T101 running Windows: Works great Samsung Galaxy Tab: Extremely slow and patchy -- unusable. Lenovo IdeaPad K1: Extremely slow and patchy -- unusable. Asus Transformer Prime: Noticeable lag compare with the iPad -- close to usable. The Asus tablet is running ICS, the other android tablets are running 3.1 and 3.2. I tested using the stock Android browser. I also tried the Android Chrome Beta, but that was even worse. My questions is why are the Android tablets so slow? Am I doing something wrong or is it an inherit problem with Android OS or browser, or is there anything I can do about it in my code? multi.html: <html> <body> <style media="screen"> canvas { border: 1px solid #CCC; } </style> <canvas style="" id="draw" height="450" width="922"></canvas> <script class="jsbin" src="jquery.js"></script> <script src="multi.js"></script> </body> </html> multi.js: var CanvasDrawr = function(options) { // grab canvas element var canvas = document.getElementById(options.id), ctxt = canvas.getContext("2d"); canvas.style.width = '100%' canvas.width = canvas.offsetWidth; canvas.style.width = ''; // set props from options, but the defaults are for the cool kids ctxt.lineWidth = options.size || Math.ceil(Math.random() * 35); ctxt.lineCap = options.lineCap || "round"; ctxt.pX = undefined; ctxt.pY = undefined; var lines = [,,]; var offset = $(canvas).offset(); var eventCount = 0; var self = { // Bind click events init: function() { // Set pX and pY from first click canvas.addEventListener('touchstart', self.preDraw, false); canvas.addEventListener('touchmove', self.draw, false); }, preDraw: function(event) { $.each(event.touches, function(i, touch) { var id = touch.identifier; lines[id] = { x : this.pageX - offset.left, y : this.pageY - offset.top, color : 'black' }; }); event.preventDefault(); }, draw: function(event) { var e = event, hmm = {}; eventCount += 1; $.each(event.touches, function(i, touch) { var id = touch.identifier, moveX = this.pageX - offset.left - lines[id].x, moveY = this.pageY - offset.top - lines[id].y; var ret = self.move(id, moveX, moveY); lines[id].x = ret.x; lines[id].y = ret.y; }); event.preventDefault(); }, move: function(i, changeX, changeY) { ctxt.strokeStyle = lines[i].color; ctxt.beginPath(); ctxt.moveTo(lines[i].x, lines[i].y); ctxt.lineTo(lines[i].x + changeX, lines[i].y + changeY); ctxt.stroke(); ctxt.closePath(); return { x: lines[i].x + changeX, y: lines[i].y + changeY }; }, }; return self.init(); }; $(function(){ var drawr = new CanvasDrawr({ id: "draw", size: 5 }); });

  • Java JNI leak in c++ process.

    - by user662056
    Hi all.. I am beginner in Java. My problem is: I am calling a Java class's method from c++. For this i am using JNI. Everythings works correct, but i have some memory LEAKS in the process of c++ program... So.. i did simple example.. 1) I create a java machine (jint res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);) 2) then i take a pointer on java class (jclass cls = env-FindClass("test_jni")); 3) after that i create a java class object object, by calling the constructor (testJavaObject = env-NewObject(cls, testConstruct);) AT THIS very moment in the process of c++ program is allocated 10 MB of memory 4) Next i delete the class , the object, and the Java Machine .. AT THIS very moment the 10 MB of memory are not free ................. So below i have a few lines of code c++ program void main() { { //Env JNIEnv *env; // java virtual machine JavaVM *jvm; JavaVMOption* options = new JavaVMOption[1]; //class paths options[0].optionString = "-Djava.class.path=C:/Sun/SDK/jdk/lib;D:/jms_test/java_jni_leak;"; // other options JavaVMInitArgs vm_args; vm_args.version = JNI_VERSION_1_6; vm_args.options = options; vm_args.nOptions = 1; vm_args.ignoreUnrecognized = false; // alloc part of memory (for test) before CreateJavaVM char* testMem0 = new char[1000]; for(int i = 0; i < 1000; ++i) testMem0[i] = 'a'; // create java VM jint res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args); // alloc part of memory (for test) after CreateJavaVM char* testMem1 = new char[1000]; for(int i = 0; i < 1000; ++i) testMem1[i] = 'b'; //Creating java virtual machine jclass cls = env->FindClass("test_jni"); // Id of a class constructor jmethodID testConstruct = env->GetMethodID(cls, "<init>", "()V"); // The Java Object // Calling the constructor, is allocated 10 MB of memory in c++ process jobject testJavaObject = env->NewObject(cls, testConstruct); // function DeleteLocalRef, // In this very moment memory not free env->DeleteLocalRef(testJavaObject); env->DeleteLocalRef(cls); // 1!!!!!!!!!!!!! res = jvm->DestroyJavaVM(); delete[] testMem0; delete[] testMem1; // In this very moment memory not free. TO /// } int gg = 0; } java class (it just allocs some memory) import java.util.*; public class test_jni { ArrayList<String> testStringList; test_jni() { System.out.println("start constructor"); testStringList = new ArrayList<String>(); for(int i = 0; i < 1000000; ++i) { // ??????? ?????? testStringList.add("TEEEEEEEEEEEEEEEEST"); } } } process memory view, after crating javaVM and java object: testMem0 and testMem1 - test memory, that's allocated by c++. ************** testMem0 ************** JNI_CreateJavaVM ************** testMem1 ************** // create java object jobject testJavaObject = env->NewObject(cls, testConstruct); ************** process memory view, after destroy javaVM and delete ref on java object: testMem0 and testMem1 are deleted to; ************** JNI_CreateJavaVM ************** // create java object jobject testJavaObject = env->NewObject(cls, testConstruct); ************** So testMem0 and testMem1 is deleted, But JavaVM and Java object not.... Sow what i do wrong... and how i can free memory in the c++ process program.

  • Featureful commercial text editors?

    - by wrp
    I'm willing to buy tools if they add genuine value over a FOSS equivalent. One thing I wouldn't mind having is an editor with the power of Emacs, but made more user-friendly. There seem to be several commercial editors out there, but I can't find much discussion of them online. Maybe it's because the kind of people who use commercial software don't have time to do much blogging. ;-) If you have used any, what was your evaluation? I'd especially like to hear how you would compare them to Emacs. I'm thinking of editors like VEDIT, Boxer, Crisp, UltraEdit, SlickEdit, etc. To get things started, I tried EditPad Pro because I needed something on a Win98SE box. I was attracted by its powerful support for regexps, but I didn't use it for long. One annoyance was that find-in-files was only available in a separate product you had to buy. The main problem, though, was stability. It sometimes hung and I lost a few files because it corrupted them while editing. After a couple weeks, I found that I was avoiding using it, so I just uninstalled. Edit: Ah...I need to remove some ambiguity. With reference to Emacs, "power" often means its potential for customization. This malleability comes from having an architecture in which most of the functionality is written in a scripting language that runs on a compiled core. Emacs (with elisp) is by far the most widely known such system among home users, but there have been other heavily used editors such as Freemacs (MINT), JED (S-Lang), XEDIT (Rexx), ADAM (TPU), and SlickEdit (Slick-C). In this case, by "power" I'm not referring to extensibility but to realized features. There are three main areas which I think a commercial text editor might be an improvement over Emacs: Stability The only apps I regularly use on Linux that give me flaky behavior are Emacs, Gedit, and Geany. On Windows, I like the look and features of Notepad++, but I find it extremely unstable, especially if I try to use the plugins. Whatever I happen to be doing, I'm using some text editor practically all day long. If I could switch to an editor that never gave me problems, it would definitely lower my stress level. Tools When I started using Emacs, I searched the manual cover to cover to gleam ideas for clever, useful things I could do with it. I'd like to see lots of useful features for editing code, based on detailed knowledge of what the system can do and the accumulated feedback of users. Polish The rule of threes goes that if you develop something for yourself, it's three times harder to make it usable in-house, and three times harder again to make it a viable product for sale. It's understandable, but free software development doesn't seem to benefit from much usability testing. BTW, texteditors.org is a fantastic resource for researching text editors.

  • My computer freezes irregularly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. Sometimes my G-15 LCD screen flickers and caracters gets caried around temporary under heavy load. Now, most of the times, the BIOS hard disks boot order gets reversed for some reason and I have to put it to the right one and save each times I boot. (Might be unrelated, not sure, but it first started yesterday) Sometimes the BIOS doesn't detect my 750GB hard drive plugged in SATA1. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 45-55. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu Ran 6 short different CPU stress test on Fedora 15 (Haven't found any complete stress testers for Linux) and it didn't crash. Changed the thermal paste to some Artic Silver 5 for my CPU and stress tested the CPU, temperature was at 50 idle, then 64 highest and slowly went down to 62 during the test. Ran some stress testing with a temporary graphic card and it went ok. Ran furmark stress test with my original graphic card and it freezed again. GPU had a temp of 74C, a CPU temp of 58C and a mobo temp of 40C or 45C (Dunno which one it is from SpeedFan). Ran a furmark stress test and a CPU stress test at the same time, results: http://pastebin.com/2t6PLpdJ I have been using my computer without stressing it for about 2 hours now and no crashes yet. I also have disabled the AMD Cool'n'quiet function on the BIOS for a more regular power to the CPU. When I ran Furmark without C'n'q my computer didn't freeze but I had a "Driver Kernel Error" that have recovered (And Furmark crashed) all that while running a CPU stress test. The computer eventually frozed without me being at it, but this time my screen just went on sleep and I couldn't wake it. Using the stability tester in nTune my computer freezed again (In the same manner as before). I notived that Speedfan gives me a -12V of -16.97V and a -5V of -8.78V. I wonder if these numbers are reliable and if they are good or bad. I have swapped my G-15 with another basic USB keyboard (HP) and I have ran furmark for about 10 minutes with a CPU stability test running each 60 seconds for 30 seconds and my computer haven't crashed yet. Ran some more extended tests without my G-15 and it freezed like it usually do. Removed the nForce Hard disk controler. Disabled command queuing in the NVIDIA nForce SATA Controller for both port 0 and port 1 (Errors from the logs) Used CPUID HwMonitor, here are the voltages: http://pastebin.com/dfM7p4jV Changed some configurations in the motherboard BIOS: Disabled PEG Link Mode, Changed AI Tuning to Standard, Disabled the 1394 Controller, Disabled HD Audio, Disabled JMicron RAID controller and Disabled SATA Raid.

  • Modify code to change timestamp timezone in sitemap

  • Getting AveragePower and PeakPower for a Channel in AVAudioRecorder

    - by Biranchi
    Hi all, I am annoyed with this piece of code. I am trying to get the averagePowerForChannel and peakPowerForChannel while recording Audio, but every time i am getting it as 0.0 Below is my code for recording audio : NSMutableDictionary *recordSetting =[[NSDictionary alloc] initWithObjectsAndKeys:[NSNumber numberWithFloat: 22050.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatLinearPCM], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, [NSNumber numberWithInt:32],AVLinearPCMBitDepthKey, [NSNumber numberWithBool:NO],AVLinearPCMIsBigEndianKey, [NSNumber numberWithBool:NO],AVLinearPCMIsFloatKey, nil]; recorder1 = [[AVAudioRecorder alloc] initWithURL:[NSURL fileURLWithPath:audioFilePath] settings:recordSetting error:&err]; recorder1.meteringEnabled = YES; recorder1.delegate=self; [recorder1 prepareToRecord]; [recorder1 record]; levelTimer = [NSTimer scheduledTimerWithTimeInterval: 0.3f target: self selector: @selector(levelTimerCallback:) userInfo: nil repeats: YES]; - (void)levelTimerCallback:(NSTimer *)timer { [recorder1 updateMeters]; NSLog(@"Peak Power : %f , %f", [recorder1 peakPowerForChannel:0], [recorder1 peakPowerForChannel:1]); NSLog(@"Average Power : %f , %f", [recorder1 averagePowerForChannel:0], [recorder1 averagePowerForChannel:1]); } What is the error in the code ???

  • iPhone metering problems

    - by Eric Christensen
    When I'm recording an AVAudioRecorder object, I repeat a chunk of code via an NSTimer that includes: [soundrecording updateMeters]; NSLog(@"channel 0 average:%f, peak:%f",[soundrecording averagePowerForChannel:0],[soundrecording peakPowerForChannel:0]); NSLog(@"channel 1 average:%f, peak:%f",[soundrecording averagePowerForChannel:1],[soundrecording peakPowerForChannel:1]); When I'm recording a mono file, the peak power for channel 0 is just what you'd expect, a float from -160 to 0. But average power for channel 0 is always zero. (And, of course, the values for channel 1 are both zero.) When I'm recording a stereo file, both the average and peak values for both channels are as expected. Any thoughts on why, when recording a mono file, the average value for channel 0 isn't returning correctly, even though the peak is? Thanks!

  • Raspberry Pi cluster, neuron networks and brain simulation

    - by jokoon
    Since the RBPI (Raspberry Pi) has very low power consumption and very low production price, it means one could build a very big cluster with those. I'm not sure, but a cluster of 100000 RBPI would take little power and little room. Now I think it might not be as powerful as existing supercomputers in terms of FLOPS or others sorts of computing measurements, but could it allow better neuronal network simulation ? I'm not sure if saying "1 CPU = 1 neuron" is a reasonable statement, but it seems valid enough. So does it mean such a cluster would more efficient for neuronal network simulation, since it's far more parallel than other classical clusters ?

  • Current state of client-side XSLT

    - by Casey
    Last I heard, Blizzard was one of the few companies to put client-side XSLT into practice (2008). Is this still the case in 2011, or are more people now exploring this technique in production?  It seems that modern browsers (IE9, FF4, Chrome) and client processing power are primed to exploit this standard for tangible savings in server CPU power and bandwidth on large scale properties. Am I missing something? The negative aspects I'm aware of include * additional rendering time * additional assets required on uncached page load * additional layer of complexity * noticably less developer experience than server-side template techniques The benefits I perceive include * distributed template composition (offloaded on the client) * caching of common template fragments offloaded on the client * logical separation of document structure and data * well-documented web standard supported by all modern browsers Finally, although I know it's impossible to predict the future, I am curious to know opinions on whether or not client-side XSLT's day will come. With interest in HTML5 driving users to upgrade their browsers and developers to explore new techniques, I would say yes. How about you? Thanks in advance, Casey

  • Plot smooth line with PyPlot

    - by Paul
    I've got the following simple script that plots a graph: import matplotlib.pyplot as plt import numpy as np T = np.array([6, 7, 8, 9, 10, 11, 12]) power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00]) plt.plot(T,power) plt.show() As it is now, the line goes straight from point to point which looks ok, but could be better in my opinion. What I want is to smooth the line between the points. In Gnuplot I would have plotted with smooth cplines. Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex.

  • Where are TFS Alerts stored in the TFS Databases? Receiving duplicate alerts after upgrade 2008 to

    - by MJ Hufford
    I recently performed a migration-upgrade from TFS 2008 to TFS 2010. Almost everything is working properly now. However, our team is getting duplicate emails now. I'm guessing this is because I used the TFS 2008 power tools to setup alerts. After the upgrade, I installed the TFS 2010 power tools and noticed that there were not alerts configured. I setup new alerts and now we get duplicates. Is it possible the old alerts configuration is floating around in the db somewhere?

  • Need to devise a number crunching algorithm

    - by Ravi Gupta
    I stumbled upon this question: 7 power 7 is 823543. Which higher power of 7 ends with 823543 ? How should I go about it ? The one I came up with is very slow, it keeps on multiplying by 7 and checks last 6 digits of the result for a match. I tried with Lou's code: int x=1; for (int i=3;i<=100000000;i=i+4){ x=(x*7)%1000000; System.out.println("i="+ i+" x= "+x); if (x==823543){ System.out.println("Ans "+i);} } And CPU sounds like a pressure cooker but couldn't get the answer :(

  • How does operating system software maintains time clocks?

    - by Neeraj
    Hi everyone, This may sound a bit less relevant but I couldn't think of a better place to ask this question. Now consider this situation, you install an OS on your system, set the timezone and time, do some stuff and turn it off. (Note that there is no power going in to the computer). Now next time (say after some hours or days) you turn it on again, and you see the updated time. How is this possible even when my computer is not connected to the internet and was consuming no power during the period it was down.(Is there some kind of hardware hack?) please clarify!

  • Google Maps API v3 - Different markers/labels on different zoom levels

    - by krikara
    I was wondering if it is possible that Google has a feature to view different markers on different zoom levels. For example, on zoom level 1, I want one marker over China with the label saying "5". And as the user zooms in, lets say on zoom level 4, I want the previous marker and label to disappear. And I want to have 5 new markers/labels, each on a different city in China all saying "1". Thus China will say a number and all the cities in China will say numbers adding up to China's number. The key concept I am trying to figure out here is how to hide markers and labels based on zoom levels. A constraint for me is that I am living in China currently where google is censored, so a lot of online documents are censored for me, including many of google's documentations. Here is my code thus far <!DOCTYPE html> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <title>TM China</title> <style type="text/css"> html, body, #map_canvas { margin: 0;

And when I copy the source code directly to my computer and replace all the icons with markers, the markers still don't appear. I can't seem to figure how to make markers appear using the marker Manager. http://google-maps-utility-library-v3.googlecode.com/svn/tags/markermanager/1.0/examples/weather_map.html

  • Controlling PowerPoint Slideshow

    - by Jayesh
    Hi, I have a scenario: There is a Slideshow running in PowerPoint. I want to control the movement [Next and Previous] of the slides. Of course it is possible with the [ and < button on the keyboard], but is there any way in which I can have a custom application listening to the Next and Previous controls? As in, my custom application has nothing but 2 buttons, next and previous, when I click either, the button's event handler should pass the control to the Power Point Application running the slideshow. And thus, the powerpoint will move the slideshow back or forward? Somewhat similar to the way remote, wireless Power Point Presenters work on the s/w end. Thank You.

  • Lua class instance with nested tables

    - by Anonnobody
    Hello, Simple lua game with simple class like so: creature = class({ name = "MONSTER BADDY!", stats = { power = 10, agility = 10, endurance = 10, filters = {} }, other_things = ... }) creatureA = creature.new() creatureB = creature.new() creatureA.name = "Frank" creatureB.name = "Zappa" creatureA.stats.agility = 20 creatureB.stats.power = 12 -- blah blah blah Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table. Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic? Q2: How would you have each instance of creature have it's own stats table (and sub tables)? PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation. Thanks a bunch.
