  • Create a triangle out of stars using only recursion

    - by Ramblingwood
    I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

  • Best cheap GUI for converting to f4v

    - by Ben
    Hi, I need to give one client the ability to convert some videos to f4v h264 before loading it up to an AIR app. I normally doing with the Adobe Media Encoder CS4 but that only ships with adobe products (you can't download it as a free standalone app - which, start rant is odd, you'd think they would push the format - Microsoft's competing expresssion encoder is free end rant) Anyway, I need to get a (hopefully not too expensive, but willing to pay for it) good 3rd part app that can take any video and convert it to an f4v. Can you suggest any? Everything i've found is horrible or jammed with ads and crap. What would you use? Any suggestion? (please don't just say ffmpeg - I know it can do it but we need to good simple GUI) Thanks!

  • R: how can I concatenate a list?

    - by John
    I'm trying to produce a single variable which is a concatenation of two chars e.g to go from "p30s4" "p28s4" to "p30s4 p28s4". I've tried cat and paste as shown below. Both return empty variables. What am I doing wrong? > blah = c("p30s4","p28s4") > blah [1] "p30s4" "p28s4" > foo = cat(blah) p30s4 p28s4 > foo NULL > foo = paste(cat(blah)) p30s4 p28s4 > foo character(0)

  • A pragmatic view on private vs public

    - by Denis Gorbachev
    Hello everybody! I've always wondered on the topic of public, protected and private properties. My memory can easily recall times when I had to hack somebody's code, and having the hacked-upon class variables declared as private was always upsetting. Also, there were (more) times I've written a class myself, and had never recognized any potential gain of privatizing the property. I should note here that using public vars is not in my habit: I adhere to the principles of OOP by utilizing getters and setters. So, what's the whole point in these restrictions?

  • Question about the lifecycle of a simple Android application

    - by jul
    Hi, I've got a simple application with 3 activities: -the first contains a search box which calls a web service and show the results (restaurants) below in a listview -when a restaurant is clicked another activity is started showing the description of the restaurant and a button "show map" -when the button "show map" is clicked, guess what, the map is shown in a third activity. All the data is loaded in the first activity by a web service (restaurant descriptions and coordinates), and data required by each activity is passed in a bundle using "intent.putExtra". Now everything seems to run smoothly when clicking on the back button (eg. clicking on the back button from the map resumes the "restaurant description" activity with all data set properly), while I haven't done anything about the lifecycle yet. Why? Are all variables saved automatically? Should I use onSaveInstanceState() and onRestoreInstanceState() anyway? Thanks Jul

  • Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

    - by cloudraven
    I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

  • Android: Width and Height of View After Orientation Change

    - by David
    I need to get the width and height of a WebView and pass them in the query string of the URL I am loading in the WebView. I have found a way to do this in onResume(). Since the width and height are not calculated at this point, I post a Runnable to the WebView to be queued for after the UI loads. Here's my problem: when the orientation changes, I am handling it in onConfigurationChanged. When I try to post a Runnable in onConfigurationChanged to the WebView, the WebView's width and height end up being the old orientation's width and height. At what point can I intercept the new width and height after orientation change?

  • C++ word to bytes

    - by Vit
    Hi, I tried to read CPUID using assembler in C++. I know there is function for it in , but I want the asm way. So, after CPUID is executed, it should fill eax,ebx,ecx registers with ASCII coded string. But my problem is, since I can in asm adress only full, or half eax register, how to break that 32 bits into 4 bytes. I used this: #include <iostream> #include <stdlib.h> int main() { _asm { cpuid /*There I need to mov values from eax,ebx and ecx to some propriate variables*/ } system("PAUSE"); return(0); }

  • local match kickoff time

    - by Usagi Dreamy
    I'm working on a sports website and need to convert the server's match start time to local match start time. After much googling, I figured the fastest and most accurate way is to get the GMT offset value in JavaScript. The trouble is, I can't pass the GMT offset value to PHP. I've tried using both the PHP session and cookie variables, but both are always empty. The website doesn't require a user account, so there isn't any stored GMT value in the database. I'm trying to auto-detect each user's local timezone every time he/she visits the website, and then calculate the local match start time based on the timezone offset. Can someone please advise me? Thanks.

  • Why is silverlight so slow? (Especially when compared to Flash)

    - by Sahat
    I hope I don't have to explain what is Silverlight to SO community. Anyway TemplateMonster.com has recently released new Silverlight themes that have been ported from Flash. Silverlight Templates | Template Monster I've noticed a significant lag on my Macbook Pro 13" in loading the template page in Silverlight. And not just Template Monster templates but other silverlight applications on the web as well. Now why is that? I've been hearing how great Silverlight is and how it's a great business platform blah blah blah. And now Microsoft plans to build Windows Phone 7 on top of Silverlight framework. As much as I want to praise Silverlight, so far it's been nothing but a disappointment to me. Could someone enlighten me, what is so great about Silverlight, and why should I put up with that starting up lag? Silverlight was really next up on my "stuff to learn" list this summer, but now I am not so sure...

  • Xcodebuild failing to pick up environment values from project file?

    - by egrunin
    I'm using Xcode 3.2.6, MacOSX. I have a globally visible environment setting: ICU_SRC=~/Documents/icu/source This really is an environment setting, it's set at login time. When I open up Terminal, it's there. In my project, under Header Search Paths I've added this: $(ICU_SRC)/i18n $(ICU_SRC)/common These expand correctly when I compile inside the IDE. When I look at the build results, I see this: -I/Users/eric.grunin/Documents/icu/source/i18n -I/Users/eric.grunin/Documents/icu/source/common When I build from the command line, however, it fails. What I see is this: -I/i18n -I/common Here's the command I'm using to compile: /usr/bin/env -i xcodebuild -project my_project.xcodeproj -target "my_program" -configuration Release -sdk macosx10.6 build What am I doing wrong? Edited to add: Apple explains Setting environment variables for user processes

  • Create custom component based on LinearLayout, declaring layout in XML

    - by pheelicks
    I've been trying to create a Compound Control in Android 1.5 (as described here) but havn't been able to find any good examples on how to do this using an XML file to specify a layout. I'm fine with creating an Activity and then loading an xml file using the following in the constructor: setContentView(R.layout.main); However, I want to do this in subclass of LinearLayout - so I can use this compound component in other XML layouts. Something along the lines of: public class CustomView extends LinearLayout { public CustomView(Context context) { super(context); setupView(); } public CustomView(Context context, AttributeSet attrs) { super(context, attrs); setupView(); } public void setupView() { setContentView(R.layout.custom); // Not possible } } What is the correct way of going about doing this?

  • Encoding gives "'ascii' codec can't encode character … ordinal not in range(128)"

    - by user140314
    I am working through the Django RSS reader project here. The RSS feed will read something like "OKLAHOMA CITY (AP) — James Harden let". The RSS feed's encoding reads encoding="UTF-8" so I believe I am passing utf-8 to markdown in the code snippet below. The em dash is where it chokes. I get the Django error of "'ascii' codec can't encode character u'\u2014' in position 109: ordinal not in range(128)" which is an UnicodeEncodeError. In the variables being passed I see "OKLAHOMA CITY (AP) \u2014 James Harden". The code line that is not working is: content = content.encode(parsed_feed.encoding, "xmlcharrefreplace") I am using markdown 2.0, django 1.1, and python 2.4. What is the magic sequence of encoding and decoding that I need to do to make this work? Thanks.

  • For what purpose does java have a float primitive type?

    - by Roman
    I heard plenty times different claims about float type in java. The most popular issues typicaly regard to converting float value to double and vice versa. I read (rather long time ago and not sure that it's actual now with new JVM) that float gives much worse performance then double. And it's also not recommended to use float in scientific applications which should have certain accuracy. I also remember that when I worked with AWT and Swing I had some problems with using float or double (like using Point2D.Float or Point2D.Double). So, I see only 2 advantages of float over double: it needs only 4 bytes while double needs 8 bytes JMM garantees that assignment operation is atomic with float variables while it's not atomic with double's. Are there any other cases where float is better then double? Do you use float's in your applications? It seems to me that the only valuable reason java has float is backward compatibility.

  • JS function returning another function

    - by Michael
    I want to understand about variables, that has been used in returning function. This is example code Prototype = {} Prototype.F = { bind: function() { var args = arguments, __method = args.shift(), object = args.shift(); return function() { return __method.apply(object, args.concat(arguments)); } } } function ObjectA() { ... this.addListener = Prototype.F.bind(this.eventSource.addListener, this.eventSource); ... } var a = ObjectA(); a.addListener(this); // assuming 'this' here will point to some window object As I understand the returning function in F() is not evaluated until it's called in the last line. It's ok to accept. So addListener will hold a function body containing 'apply'. But what I don't understand, when addListener is called, what kind of parameters it is going to have? particularly _method and args will always be uninitialized?

  • Posting null values via AJAX

    - by nickf
    Using the jQuery $.post function, if you send a null value, it arrives at the server side as "null". Example: Javascript: $.post('test.php', { foo : null }); PHP: var_dump($_POST['foo']); // string(4) "null" I understand why this is so, but was wondering the best way to work around the limitation? Should you: Loop through all the variables in JS before you send them and replace with an empty string? Interpret "null" as null on the server side? Don't send the variable at all? Something else?

  • Why doesn't CSS support constants?

    - by Adiel Mittmann
    CSS has never supported constants or variables directly. Whenever I'm writing code like this: span.class1 { color: #377fb6; } div.class2 { border: solid 1px #377fb6; /* Repeated color */ } I wonder why such a seemingly simple feature has never made it into the standard. What could be hard about implementing a scheme whereby we could avoid repetition, something like this: $theme_color1: #377fb6; span.class1 { color: $theme_color1; } div.class2 { border: solid 1px $theme_color1; } I know there are workarounds, like using a class for each color or generating CSS code from templates, but my question is: given that CSS is so rich and complex, why weren't CSS constants ever introduced?

  • turning text into image - PHP/GD - save image

    - by Phil Jackson
    Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser; // an email address in a string $string = $post[$key]; // some variables to set $font = 4; $width = ImageFontWidth($font) * strlen($string); $height = ImageFontHeight($font); // lets begin by creating an image $im = @imagecreatetruecolor ($width,$height); //white background $background_color = imagecolorallocate ($im, 255, 255, 255); //black text $text_color = imagecolorallocate ($im, 0, 0, 0); // put it all together $image = imagestring ($im, $font, 0, 0, $string, $text_color); I know its probably just one line of code at the end but im not sure which GD function to use. Any help would be much appreciated, Regards, Phil.

  • PHP: passing GET between multiple pages

    - by aterimperator
    I'm building a set of pages where I have a number of GET variables and it is often valuable to keep passing it along to the next page. This leads to ugly code where I have to have "if this $_GET variable is set, dynamically add it to this hyperlink". This is, in many senses, not a problem; but I had the thought "there must be a better way to do this", I mean after all basically all I want is to take the '?' and everything after it and append it to the links on that page, it would seem this should be rather simple (or at least possible to do in a for loop). I tried google searching but couldn't find anything, so I figured I'd see if any of you happen to know. Why not use SESSION? Because these pages need to be capable of being bookmarked. Thank you.

  • NSURL not instantiating properly

    - by taokakao
    Hi, I am new to IPhone developing. I have got very strange issue with NSURL which is driving me crazy. I want to instantiate NSURL object to use it in loading image. But instantiation never happens in proper way. It always says my url in invalid. Basically I use code like below: NSString *str = @"http://google.com"; NSURL *url = [NSURL URLWithString:str]; but I also have tried a lot of different modifications (with CFStringRef + CFURLCreateStringByAddingPercentEscapes and so on). All of them are not working for me. In debugger url is set to "Invalid". What it could be? I don't think this is algorithmic or environment issue. It could be about some settings? Have anyone any idea of what happens?

  • how is this jquery app validating the username? (3rd party script)

    - by SarmenHB
    The tutorial that I'm trying to figure out is this: http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/ The username field looks like this: <input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" /> That <input> field has a class item named ajax[ajaxUser] which has its rules contained in this script (jquery.validationEngine-en.js). The snippet for that item looks like this: "ajaxUser":{ "file":"validateUser.php", "extraData":"name=eric", "alertTextOk":"* This user is available", "alertTextLoad":"* Loading, please wait", "alertText":"* This user is already taken"}, What I can't figure out at all is how its PHP page is working which is validateUser.php. Where are all those post fields coming from? I looked around and can't find a field with those names. Thanks

  • How does an interpreter switch scope?

    - by Dox
    I'm asking this because I'm relatively new to interpreter development and I wanted to know some basic concepts before reinventing the wheel. I thought of the values of all variables stored in an array which makes the current scope, upon entering a function the array is swapped and the original array put on some sort of stack. When leaving the function the top element of the "scope stack" is popped of and used again. Is this basically right? Isn't swapping arrays (which means moving around a lot of data) not very slow and therefore not used by modern interpreters?

  • How to get the first non-null value in Java?

    - by froadie
    Is there a Java equivalent of SQL's COALESCE function? That is, is there any way to return the first non-null value of several variables? e.g. Double a = null; Double b = 4.4; Double c = null; I want to somehow have a statement that will return the first non-null value of a, b, and c - in this case, it would return b, or 4.4. (Something like the sql method - return COALESCE(a,b,c)). I know that I can do it explicitly with something like: return a != null ? a : (b != null ? b : c) But I wondered if there was any built-in, accepted function to accomplish this.

  • Write a GreaseMonkey script that reacts to domain strings (for I18N, e.g. cn,en,fr,etc.)

    Hello. Suppose there is a website that supports multiple languages: cn.mydomain.com or mydomain.com/cn or mydomain.cn en.mydomain.com or mydomain.com/en or mydomain.com fr.mydomain.com or mydomain.com/fr or mydomain.fr I want to write a GreaseMonkey script that has variables assigned different strings/values according to the address the user is loading the page from. How do you do that? Thanks EDIT: I realize I can just use JavaScript to get the address. Does GreaseMonkey itself support this kind of function?
