    - by Tuffy G
    I want to start making a program for a local charity on the Android platform. Where can go I for resources and tutorials to learn? I'm very new at this, so would like something simple that can be followed by someone with minimal technical knowledge.

  • Initializing AngularJS service factory style

    - by wisemanIV
    I have a service that retrieves data via REST. I want to store the resulting data in service level variable for use in multiple controllers. When I put all the REST logic directly into controllers everything works fine but when I attempt to move the retrieval / storing of data into a service the controller is not being updated when the data comes back. I've tried lots of different ways of maintain the binding between service and controller. Controller: myApp.controller('SiteConfigCtrl', ['$scope', '$rootScope', '$route', 'SiteConfigService', function ($scope, $rootScope, $route, SiteConfigService) { $scope.init = function() { console.log("SiteConfigCtrl init"); $scope.site = SiteConfigService.getConfig(); } } ]); Service: myApp.factory('SiteConfigService', ['$http', '$rootScope', '$timeout', 'RESTService', function ($http, $rootScope, $timeout, RESTService) { var siteConfig = {} ; RESTService.get("https://domain/incentiveconfig", function(data) { siteConfig = data; }); return { getConfig:function () { console.debug("SiteConfigService getConfig:"); console.debug(siteConfig); return siteConfig; } }; } ]);

  • C# style properties in python

    - by 3D-Grabber
    I am looking for a way to define properties in Python similar to C#, with nested get/set definitions. This is how far I got: #### definition #### def Prop(fcn): f = fcn() return property(f['get'], f['set']) #### test #### class Example(object): @Prop def myattr(): def get(self): return self._value def set(self, value): self._value = value return locals() # <- how to get rid of this? e = Example() e.myattr = 'somevalue' print e.myattr The problem with this is, that it still needs the definition to 'return locals()'. Is there a way to get rid of it? Maybe with a nested decorator?

  • Javascript style objects in Objective-C

    - by awolf
    Background: I use a ton of NSDictionary objects in my iPhone and iPad code. I'm sick of the verbose way of getting/setting keys to these state dictionaries. So a little bit of an experiment: I just created a class I call Remap. Remap will take any arbitrary set[VariableName]:(NSObject *) obj selector and forward that message to a function that will insert obj into an internal NSMutableDictionary under the key [vairableName]. Remap will also take any (zero argument) arbitrary [variableName] selector and return the NSObject mapped in the NSMutableDictionary under the key [variableName]. e.g. Remap * remap = [[Remap alloc] init]; NSNumber * testNumber = [NSNumber numberWithInt:46]; [remap setTestNumber:testNumber]; testNumber = [remap testNumber]; [remap setTestString:@"test string"]; NSString * testString = [remap testString]; NSMutableDictionary * testDict = [NSMutableDictionary dictionaryWithObject:testNumber forKey:@"testNumber"]; [remap setTestDict:testDict]; testDict = [remap testDict]; where none of the properties testNumber, testString, or testDict are actually defined in Remap. The crazy thing? It works... My only question is how can I disable the "may not respond to " warnings for JUST accesses to Remap? P.S. : I'll probably end up scrapping this and going with macros since message forwarding is quite inefficient... but aside from that does anyone see other problems with Remap? Here's Remap's .m for those who are curious: #import "Remap.h" @interface Remap () @property (nonatomic, retain) NSMutableDictionary * _data; @end @implementation Remap @synthesize _data; - (void) dealloc { relnil(_data); [super dealloc]; } - (id) init { self = [super init]; if (self != nil) { NSMutableDictionary * dict = [[NSMutableDictionary alloc] init]; [self set_data:dict]; relnil(dict); } return self; } - (void)forwardInvocation:(NSInvocation *)anInvocation { NSString * selectorName = [NSString stringWithUTF8String: sel_getName([anInvocation selector])]; NSRange range = [selectorName rangeOfString:@"set"]; NSInteger numArguments = [[anInvocation methodSignature] numberOfArguments]; if (range.location == 0 && numArguments == 4) { //setter [anInvocation setSelector:@selector(setData:withKey:)]; [anInvocation setArgument:&selectorName atIndex:3]; [anInvocation invokeWithTarget:self]; } else if (numArguments == 3) { [anInvocation setSelector:@selector(getDataWithKey:)]; [anInvocation setArgument:&selectorName atIndex:2]; [anInvocation invokeWithTarget:self]; } } - (NSMethodSignature *) methodSignatureForSelector:(SEL) aSelector { NSString * selectorName = [NSString stringWithUTF8String: sel_getName(aSelector)]; NSMethodSignature * sig = [super methodSignatureForSelector:aSelector]; if (sig == nil) { NSRange range = [selectorName rangeOfString:@"set"]; if (range.location == 0) { sig = [self methodSignatureForSelector:@selector(setData:withKey:)]; } else { sig = [self methodSignatureForSelector:@selector(getDataWithKey:)]; } } return sig; } - (NSObject *) getDataWithKey: (NSString *) key { NSObject * returnValue = [[self _data] objectForKey:key]; return returnValue; } - (void) setData: (NSObject *) data withKey:(NSString *)key { if (key && [key length] >= 5 && data) { NSRange range; range.length = 1; range.location = 3; NSString * firstChar = [key substringWithRange:range]; firstChar = [firstChar lowercaseString]; range.length = [key length] - 5; // the 4 we have processed plus the training : range.location = 4; NSString * adjustedKey = [NSString stringWithFormat:@"%@%@", firstChar, [key substringWithRange:range]]; [[self _data] setObject:data forKey:adjustedKey]; } else { //assert? } } @end

  • "Winamp style" spectrum analyzer

    - by cvb
    I have a program that plots the spectrum analysis (Amp/Freq) of a signal, which is preety much the DFT converted to polar. However, this is not exactly the sort of graph that, say, winamp (right at the top-left corner), or effectively any other audio software plots. I am not really sure what is this sort of graph called (if it has a distinct name at all), so I am not sure what to look for. I am preety positive about the frequency axis being base two exponential, the amplitude axis puzzles me though. Any pointers?

  • Tools for displaying text, powerpoint style, in linux

    - by Will Mc
    I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would. My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously. So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need. Thanks!

  • Generic applet style system for publishing mathematics demonstrations?

    - by Alex
    Anyone who's tried to study mathematics using online resources will have come across these Java applets that demonstrate a particular mathematical idea. Examples: http://www.math.ucla.edu/~tao/java/Mobius.html http://www.mathcs.org/java/programs/FFT/index.html I love the idea of this interactive approach because I believe it is very helpful in conveying mathematical principles. I'd like to create a system for visually designing and publishing these 'mathlets' such that they can be created by teachers with little programming experience. So in order to create this app, i'll need a GUI and a 'math engine'. I'll probably be working with .NET because thats what I know best and i'd like to start experimenting with F#. Silverlight appeals to me as a presentation framework for this project (im not worried about interoperability right now). So my questions are: does anything like this exist already in full form? are there any GUI frameworks for displaying mathematical objects such as graphs & equations? are there decent open source libraries that exposes a mathematical framework (Math.NET looks good, just wondering if there is anything else out there) is there any existing work on taking mathematical models/demos built with maple/matlab/octave/mathematica etc and publishing them to the web?

  • T-SQL stored procedure to return google style "suggested" search results

    - by stephen776
    Ok, using SQL Server 2008. On my web page I have a textbox with jQuery-UI AutoComplete hooked up. Now I need a stored procedure to search across all columns of a single table(or multiple joined tables I suppose) for a search string coming from the textbox/autocomplete AJAX call, and return "suggested" search strings. I am using the AdventureWorks db for testing(Products table) So for example, the product table has columns for product name and product number(among others) and I want to return suggested search strings based on user input where they may enter a product name and/or a product number. I have it working across a single column which was simple. Any ideas?

  • Javascript code refactoring and assessment

    - by neitony
    I'm using javascript to toggle the display state of some objects based on the time of day. A sample of the code is given below. I was wondering if anyone could give a suggestion as to how I can refactor this code while at the same time improving the logic. switch(tcode) { case 'eur' : eur.setAttribute('style', 'display:block; opacity:0.5'); us.style.display = 'none'; asia.style.display = 'none'; us_inactive.style.display = 'block'; asia_inactive.style.display = 'block'; break; case 'us' : us.style.display = 'block'; eur.style.display = 'none'; asia.style.display = 'none'; eur_inactive.style.display = 'block'; asia_inactive.style.display = 'block'; break; case 'asia' : asia.setAttribute('style', 'display:block; opacity:0.5'); us.style.display = 'none'; eur.style.display = 'none'; eur_inactive.style.display = 'block'; us_inactive.style.display = 'block';

  • Stopping a MATLAB GUI callback

    - by leonhart88
    Dear All, I have a START and STOP button. When I hit START, i run a bunch of code in my callback. It's basically a sequential "script" that opens valves, dispenses water and then closes the valves...there is no while() loop and it doesn't repeat. I want to be able to stop this process at any time using the STOP button. Most of the related answers I've seen are in the cases where a while() loop is used. Some people have also suggested to periodically check if the STOP button was pressed (using a variable or handle variable). Since I do not have a while loop, I can't solve it that way. Also, I'd like to be able to exit immediately, without having to periodically check (because checking multiple times in my code would be ugly and confusing). Is there a way to terminate the callback which was interrupted by the STOP button? If not, is it possible to have the START button run a .m file and then have the STOP button terminate that .m file? The worst case scenario would be to check a variable periodically. UPDATE: Well, looks like the worst case scenario is what is suggested by MATLAB... http://www.mathworks.com/support/solutions/en/data/1-33IK85/index.html?product=ML&solution=1-33IK85 Thanks.

  • CSS Print Style Sheets - Examples

    Trying to learn about how to effectively use print.css, so that graphical and navigational elements are not shown in print preview/print. Read some articles, and part of print css of html5 boilerplate. Two sites, which was quite impressive the way they change the look during print are http://css-tricks.com/ http://bottlerocketcreative.com/ But I cannot see the css related to print. Can you please point to the css they use to learn how to do similar transformation. thanks.

  • Declaring an integer Range with step != 1 in Ruby

    - by Dan Tao
    Hey guys, I'm completely new to Ruby, so be gentle. Say I want to iterate over the range of even numbers from 2 to 100; how would I do that? Obviously I could do: (2..100).each do |x| if x % 2 == 0 # my code end end But, obviously (again), that would be pretty stupid. I know I could do something like: i = 2 while i <= 100 # my code i += 2 end I believe I could also write my own custom class that provides its own each method (?). I am almost sure that would be overkill, though. I'm interested in two things: Is it possible to do this with some variation of the standard Range syntax (i.e., (x..y).each)? Either way, what would be the most idiomatic "Ruby way" of accomplishing this (using a Range or otherwise)? Like I said, I'm new to the language; so any guidance you can offer on how to do things in a more typical Ruby style would be much appreciated.

  • In Eclipse, how do I change the default modifiers in the class/type template?

    - by gustafc
    Eclipse's default template for new types (Window Preferences Code Style Code Templates New Java Files) looks like this: ${filecomment} ${package_declaration} ${typecomment} ${type_declaration} Creating a new class, it'll look something like this: package pkg; import blah.blah; public class FileName { // Class is accessible to everyone, and can be inherited } Now, I'm fervent in my belief that access should be as restricted as possible, and inheritance should be forbidden unless explicitly permitted, so I'd like to change the ${type_declaration} to declare all classes as final rather than public: package pkg; import blah.blah; final class FileName { // Class is only accessible in package, and can't be inherited } That seems easier said than done. The only thing I've found googling is a 2004 question on Eclipse's mailing list which was unanswered. So, the question in short: How can I change the default class/type modifiers in Eclipse? I'm using Eclipse Galileo (3.5) if that matters.

  • PHP/CSS issue, one account has a fine style, the other is weird

    - by HighFlyerPL185
    Hello there, I am currently having the above issue, where on a CMS called phpVMS a CSS displaying front page works fine on the first account, but does not on any other user accounts. This only applies to the frontpage, and all of the tags seem to be closed. The top half of the picture is how it should display and how it displays for user GSM1001. The bottom half is for users GSM1002 upwards. I am really puzzled and I'd appreciate any suggestions. I am happy to post snippets of the code here or on jsFiddle if you require to see it. Thank you, kind regards.

  • Interface with inner implementation - good or bad

    - by dermoritz
    I am working on a project with many someInterface - someInterfaceImpl-pairs. Some days ago I got the idea (probably inspired by reading some objective c code) to include the default implementations as an inner class. Now some colleagues (all with much more java experience than me) saw this idea - feedback was between shocked and surprised ("this is working?"). I googled around a bit but didn't find much evidence of usefulness of this "pattern" (personal i like it): pdf-paper and a faq about code style What do you think - especially in those cases where an "default" implementation is tightly coupled to an interface. Update i just found this: Java Interface-Implementation Pair (see accepted answer)

  • Pre-done SQLs to be converted to Rails' style moduls

    - by Hoornet
    I am a Rails newbie and would really appreciate if someone converted these SQLs to complete modules for rails. I know its a lot to ask but I can't just use find_by_sql for all of them. Or can I? These are the SQLs (they run on MS-SQL): 1) SELECT STANJA_NA_DAN_POSTAVKA.STA_ID, STP_DATE, STP_TIME, STA_OPIS, STA_SIFRA, STA_POND FROM STANJA_NA_DAN_POSTAVKA INNER JOIN STANJA_NA_DAN ON(STANJA_NA_DAN.STA_ID=STANJA_NA_DAN_POSTAVKA.STA_ID) WHERE ((OSE_ID=10)AND (STANJA_NA_DAN_POSTAVKA.STP_DATE={d '2010-03-30'}) AND (STANJA_NA_DAN_POSTAVKA.STP_DATE<={d '2010-03-30'})) 2) SELECT ZIGI_OBDELANI.OSE_ID, ZIGI_OBDELANI.DOG_ID AS DOG_ID, ZIGI_OBDELANI.ZIO_DATUM AS DATUM, ZIGI_PRICETEK.ZIG_TIME_D AS ZIG_PRICETEK, ZIGI_KONEC.ZIG_TIME_D AS ZIG_KONEC FROM (ZIGI_OBDELANI INNER JOIN ZIGI ZIGI_PRICETEK ON ZIGI_OBDELANI.ZIG_ID_PRICETEK = ZIGI_PRICETEK.ZIG_ID) INNER JOIN ZIGI ZIGI_KONEC ON ZIGI_OBDELANI.ZIG_ID_KONEC = ZIGI_KONEC.ZIG_ID WHERE (ZIGI_OBDELANI.OSE_ID = 10) AND (ZIGI_OBDELANI.ZIO_DATUM = {d '2010-03-30'}) AND (ZIGI_OBDELANI.ZIO_DATUM <= {d '2010-03-30'}) AND (ZIGI_PRICETEK.ZIG_VELJAVEN < 0) AND (ZIGI_KONEC.ZIG_VELJAVEN < 0) ORDER BY ZIGI_OBDELANI.OSE_ID, ZIGI_PRICETEK.ZIG_TIME ASC 3) SELECT STA_ID, SUM(STP_TIME) AS SUM_STP_TIME, COUNT(STA_ID) FROM STANJA_NA_DAN_POSTAVKA WHERE ((STP_DATE={d '2010-03-30'}) AND (STP_DATE<={d '2010-03-30'}) AND (STA_ID=3) AND (OSE_ID=10)) GROUP BY STA_ID 4) SELECT DATUM, TDN_ID, TDN_OPIS, URN_OPIS, MOZNI_PROBLEMI, PRIHOD, ODHOD, OBVEZNOST, ZAKLJUCEVANJE_DATUM FROM OBRACUNAJ_DAN WHERE ((OSE_ID=10) AND (DATUM={d '2010-02-28'}) AND (DATUM<={d '2010-03-30'})) ORDER BY DATUM These SQLs are daily working hours and I got them as is. Also I got Database with it which (as you can see from the SQL-s) is not in Rails conventions. As a P.S.: 1)Things like STP_DATE={d '2010-03-30'}) are of course dates (in Slovenian date notation) and will be replaced with a variable (date), so that the user could choose date from and date to. 2) All of this data will be shown in the same page in the table,so maybe all in one module? Or many?; if this helps, maybe. So can someone help me? Its for my work and its my 1st project and I am a Rails newbie and the bosses are getting inpatient(they are getting quite loud actually) Thank you very very much!

  • NoMethodError using Memcached Sinatra-style

    - by sevennineteen
    I've just installed Memcached on my Mac and updated my Sinatra app configuration as described in Heroku's documentation, but I'm getting a NoMethodError when trying to use the hash-based syntax they specify: >> CACHE['color'] = 'blue' >> CACHE['color'] Using explicit get and set methods as below seems to work fine. >> CACHE.set('color', 'blue') >> CACHE.get('color') If necessary I can use the latter syntax, but the former seems more elegant. I haven't tested this on Heroku's environment since I'd like whatever implementation I use to work on my local environment as well. Thanks!

  • How to Change Style of Parent <li> on Hover

    I have a WordPress site (on my localhost) that uses a <ul> for a custom menu. How can I change the CSS of a <li> on hover only if it has a <ul> sub-menu? All the main menu items have a border-radius and I want to remove this on the current item (Services, below) for example: <div class="main-nav"> <ul class="menu" id="menu-main-nav"> <li><a href="#">Home</a></li> <li><a href="#">Services</a> <ul class="sub-menu"> <li><a href="#">Item One</a></li> <li><a href="#>Item Two</a></li> </ul> </li> <li><a href="#>Contact</a></li> </ul> </div> I can't find a CSS solution and I've tried jQuery too: $('ul.sub-menu').parent().hover(function(){ $(this).addClass('no-radius'); });
