• What kind of icon should I deploy with my Android 1.x and 2.x application?

  - by licorna

  The thing is this, in Android 1.5 and 1.6 we had the Icon Design Guidelines. In this guide there are specifications for application icons. Every application should conform to this. However, in recent Android versions (2.0 and 2.1) icons have changed from the old to this new flat 2D style. Every icon in Nexus One has this style, so not even Google is conforming to the guideline. To see the differences between high and low density icons see this image and compare Evernote icon with the rest. I've been able to use different icons by using two directories with different icons: drawables-hdpi/icon.png and drawables/icon.png, BUT not every Android 2.x is going to be HDPI and not every 1.x Android device is going to be low pixel density. So the question is: Should I deploy different icons for different Android platform version within my apk file? and if I should, How do I do it?

• Lightweight PHP library alternative to common frameworks

  - by artarad

  Hi hi, I'm looking for a easy to learn php library to use for my coming web app project. I've recently finished a web app with fully handwritten raw php code and it's absolutely hard to be done again for another project. even though I have the recent project code snippets to be used again, but due to their non-structural arrangement (not object oriented), i have no passion to use 'em again. I have no experience with common frameworks like ZF, CakePhp, CodeIgniter, so I think to get my hands on a multipurpose OO library for my web app and the framework learning will be the next step! any suggestion? UPDATE: Many thanks guys, I have not enough time to get through the depth of every lib or framework you have kindly introduced. Since I'm going one step further I'm going to use ZF as famous framework which could provide me more job opportunities perhaps. thankssss :)

• Monkeypatch a model in a rake task to use a method provided by a plugin?

  - by gduquesnay.mp

  During some recent refactoring we changed how our user avatars are stored not realizing that once deployed it would affect all the existing users. So now I'm trying to write a rake task to fix this by doing something like this. namespace :fix do desc "Create associated ImageAttachment using data in the Users photo fields" task :user_avatars => :environment do class User # Paperclip has_attached_file :photo ... <paperclip stuff, styles etc> end User.all.each do |user| i = ImageAttachment.new i.photo_url = user.photo.url user.image_attachments << i end end end When I try running that though I'm getting undefined method `has_attached_file' for User:Class I'm able to do this in script/console but it seems like it can't find the paperclip plugin's methods from a rake task.

• Using a "local" S3 emulation layer as a replacement for HDFS?

  - by user183394

  I have been testing out the most recent Cloudera CDH4 hadoop-conf-pseudo (i.e. MRv2 or YARN) on a notebook, which has 4 cores, 8GB RAM, an Intel X25MG2 SSD, and runs a S3 emulation layer my colleagues and I wrote in C++. The OS is Ubuntu 12.04LTS 64bit. So far so good. Looking at Setting up hadoop to use S3 as a replacement for HDFS, I would like to do it on my notebook. Nevertheless, I can't find where I can change the jets3t.properties for setting the end point to localhost. I downloaded the hadoop-2.0.1-alpha.tar.gz and searched the source without finding out a clue. There is a similar Q on SO Using s3 as fs.default.name or HDFS?, but I want to use our own lightweight and fast S3 emulation layer, instead of AWS S3, for our experiments. I would appreciate a hint as to how I can change the end point to a different hostname. Regards, --Zack

• Signing an unsigned assembly

  - by dagda1

  The recent upgrade of NHibernate 2.1 has brought a mega headache situation to the surface. It seems most of the projects build by default as signed assemblies. For example fluentnhibernate references the keyfile fluent.snk. Nhibernate.search builds unsigned from what I can gather and will not build signed that is if you reference a generated keyfile, you get the error: Referenced assembly 'Lucene.Net' does not have a strong name This means projects like castle.activerecord that have nhibernate.search as a dependency will not build as you get the horrendous error referenced assembly nhibernate.search does not have a strong name: Quite a few projects use caslte.activerecord so it is quite important that this builds. Has anyone any idea what to do here as I am totally out of ideas? This is complete madness.

• Setting up boost filesystem

  - by brit

  I've been having serious problems trying to set up boost. I must have installed and uninstalled the libraries a dozen times. In my most recent attempt, I followed these instructions: Download the zip and unzip it. Get the prebuilt jam executable and unzip it. Put that directory in your path. (Edit Path by using Control Panel...System..Advanced....Environemnt Variables) Open Visual Studio command prompt. Browse to boost directory. Run: bjam "-sTOOLS=vc-8_0" install The main reason I'm trying to use boost is for boost/filesystem yet nothing is working. I know this question has been asked before, but it only resulted in more errors.. Please Help!

• Jquery each loop with json array

  - by Ben

  I'm trying to use Jquery's each loop to go through this Json and add it to a div named #contentHere. The Json is as follows: { "justIn": [ { "textId": "123", "text": "Hello", "textType": "Greeting" }, { "textId": "514", "text":"What's up?", "textType": "Question" }, { "textId": "122", "text":"Come over here", "textType": "Order" } ], "recent": [ { "textId": "1255", "text": "Hello", "textType": "Greeting" }, { "textId": "6564", "text":"What's up?", "textType": "Question" }, { "textId": "0192", "text":"Come over here", "textType": "Order" } ], "old": [ { "textId": "5213", "text": "Hello", "textType": "Greeting" }, { "textId": "9758", "text":"What's up?", "textType": "Question" }, { "textId": "7655", "text":"Come over here", "textType": "Order" } ] } I'm getting this Json through use of this code: $.get("data.php", function(data){ }) Any solutions?

• Does the 80/20 rule of time management apply to developers?

  - by Dean

  Jeff's recent article linked to a time management example of the First Fit Decreasing algorithm, which talked about the Pareto principle (or, the 80/20 rule) of time management, that is, that 80% of the work we produce in 20% of our time. Now we've all heard the programmer quote: The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time. But all jokes aside, it is often as if 20% of your code is to do what you want, and the other 80% is to handle exceptions... so does the 80/20 rule really apply to developers? Does anyone have any examples of why it does / does not apply to us?

• JQUERY nav problem

  - by turborogue

  This is part 2 of a different problem that I was having... Hopefully this is about as simple as you can get, but I'm clearly missing something..... The gist is, I'm trying to get a mouseover effect using jquery/css with a mix of background images and colors. It's mostly there, but the issue that I'm having at the moment is, I mouseover the main nav = fine, I mouseover the subnav = fine, I mouse BACK over to that same main nav element, and it's OFF state kicks in instead of remaining ON as it's supposed to... I pasted my code here (since it's kinda long, and apparently I can only paste one link....) http://tinypaste.com/2222e -- a link to my most recent efforts is at the bottom of that pastebin -- hopefully the gist of what I'm trying to do will be clear. I'll keep plugging away for a while, but any help would be greatly appreciated!!:)

• Last in First out UDP structure in MatLab.

  - by D Zondervan

  I am using MatLabs UDP function in their instrument control toolbox to send data packets from one computer to another. The first computer is constantly updating data values and sending them to the other computer, and I want that computer to be able to query the first one for the most recent values whenever it needs them. However, the default implementation of the UDP send and receive in MatLab is a FIFO structure- the first packet I send is the first the other computer receives when they execute the "fscanf" function. I want the last packet I sent to be the one the fscanf function returns. Is this possible or do I need to use a different protocol?

• Modern, Non-trivial, Pygame Tutorials?

  - by Gregg Lind

  What are some 'good', non-trivial Pygame tutorials? I realize good is relative. As an example, a good one (to me) is the one that describes how to use pygame.camera. It's recent uses a modern PyGame (1.9) non-trivial, in that it shows how to use it the module for a real application. I'd like to find others. A lot of the ones on the Pygame site are from 1.3 era or earlier! Info on related projects, like Gloss is welcome as well. (If your answer is "read the source of some pygame games", please link to the source of particular ones and note what is good about them)

• Accessing a dictionary value by custom object value in Python?

  - by Sam

  So I have a square that's made up of a series of points. At every point there is a corresponding value. What I want to do is build a dictionary like this: class Point: def __init__(self, x, y): self._x = x self._y = y square = {} for x in range(0, 5): for y in range(0, 5): point = Point(x,y) square[point] = None However, if I later create a new point object and try to access the value of the dictionary with the key of that point it doesn't work.. square[Point(2,2)] Traceback (most recent call last): File "<pyshell#19>", line 1, in <module> square[Point(2,2)] KeyError: <__main__.Point instance at 0x02E6C378> I'm guessing that this is because python doesn't consider two objects with the same properties to be the same object? Is there any way around this? Thanks

  - by Shankhoneer Chakrovarty

  I am trying to learn the following things: How mp3 file looks like internally? I found this: http://mpgedit.org/mpgedit/mpeg_format/MP3Format.html but it seems old. Is there any recent changes to the format? I couldnt find any. How to open a mp3 file in java and look for bytes? I tried using audiostream but I am getting a lot of zeros and signed short integers which nowhere resemble the header/body format as mentioned in the above link. Am I wrong in interpreting the bytes?

  Hi. I'm developing a simple application for Blackberry and i'm using Google's gson to retrieve some data from a server.

When I run the application in the simulator it show this error: "Uncaught: RuntimeException" on that annoying white screen of death and after holding the click button I can see that there is an alert dialog that says "Module 'gson-1.4' not found". However I did added "gson-1.4.jar" in the Project's Properties - Java Build Path - Add External JARs... also, the Gson objects are recognized at my code, no syntax errors at my code. BTW, I'm using Eclipse and the most recent Blackberry SDK Please help

• Mac dashboard widgets not loading external images

  - by andrhamm

  I set out to make a quick Mac OS X dashboard widget. I read the documentation and was pleased to find out they use simple HTML, JS, and CSS. I created my widget and it works when I open the .html file in Firefox, but it does not work when I install the widget to the dashboard. The widget is simple: it displays the most recent image from a weather web cam stream. The image URLs look like this: http://webcam.com/stream.jpg?1274213999617. The timestamp is appended to the URL and the server automatically responds with the latest image for that time. I did not write the server script. The widget appears to be loading correctly, but the web cam image will not load. Notice the blue question mark in the upper left. The image should appear over the square background image. Is there any special procedure for loading external images into a widget?

• immutable strings vs std::string

  - by Caspin

  I've recent been reading about immutable strings, here and here as well some stuff about why D chose immutable strings. There seem to be many advantages. trivially thread safe more secure more memory efficient in most use cases. cheap substrings (tokenizing and slicing) Not to mention most new languages have immutable strings, D2.0, Java, C#, Python, Ruby, etc. Would C++ benefit from immutable strings? Is it possible to implement an immutable string class in c++ (or c++0x) that would have all of these advantages?

• How should I do custom sort in Python 3?

  - by S.Mark

  In Python 2.x, I could pass custom function to sorted and .sort functions >>> x=['kar','htar','har','ar'] >>> >>> sorted(x) ['ar', 'har', 'htar', 'kar'] >>> >>> sorted(x,cmp=customsort) ['kar', 'htar', 'har', 'ar'] Because, in My language, consonents are comes with this order "k","kh",....,"ht",..."h",...,"a" But In Python 3.x, looks like I could not pass cmp keyword >>> sorted(x,cmp=customsort) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'cmp' is an invalid keyword argument for this function Is there any alternatives or should I write my own sorted function too?

• Error running celeryd

  I'm posting this question (and answer) so if anybody else has this problem in the future, you'll be able to google it. If you are trying to run celeryd in Django like so: python manage.py celeryd You can receive the following error immediately after it has started: celery@eric-desktop-dev has started. Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) <... snip ...> File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/connection.py", line 134, in __init__ self._x_start_ok(d, login_method, login_response, locale) File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/connection.py", line 704, in _x_start_ok args.write_longstr(response) File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/serialization.py", line 352, in write_longstr self.write_long(len(s)) TypeError: object of type 'NoneType' has no len() A rather cryptic error message, with no real clue as to where to go to fix the problem.

• module compiled with swig not found by python

  Hello, I've a problem with SWIG and python. I've a c-class that compiles correctly, but the python script says it can't find the module. I compile with: swig -c++ -python codes/codes.i g++ -c -Wall -O4 -fPIC -pedantic codes/*.cc g++ -I/usr/include/python2.6 -shared codes/codes_wrap.cxx *.o -o _codes.so This gives me a _codes.so file, as I would expect, but then I have this python file: import sys import codes (rest of the code omitted) It gives me: Traceback (most recent call last): File "script.py", line 3, in <module> import codes ImportError: No module named codes According to http://www.swig.org/Doc1.3/Introduction.html#Introduction_nn8 this is all I should have to do... The files are in the same directory, so the path should not be a problem ?

• How to branch with TortoiseHG

  - by Michael Tiller

  I downloaded TortoiseHg 1.0 for evaluation. For the life of me I can't figure out how to make a branch. It seems to understand branches (e.g. in its repository browser) but I just can't seem to find a way to make a branch. This seems like such a fundamental capability since out of the often touted benefits of DVC is the lightweight branching. I Googled around and couldn't find much discussion of this topic (at least for recent versions) so I have to assume I'm missing something, right?

• [BUG] Bus Error - What causes this in Ruby?

  - by viatropos

  I have run into this error 5 or 10 times over the past few years and have never found a clear answer to this problem. Here is the error: $ rake db:migrate /usr/lib/ruby/gems/1.8/gems/libxml-ruby-0.9.5/lib/libxml_ruby.bundle: [BUG] Bus Error ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0] Abort trap The app I am running this in is using RMagick. I have run into this problem when installing ImageMagick a while ago, and when installing Nokogiri, and when installing MySQL. For Nokogiri it was because I needed a more recent version of libxml. What are your thoughts on this? Any fixes? How can I check the version of RMagick the project is loading? I am on a Mac, 10.5.8. Thanks for the help, Lance
