问题 I have followed the procedure to set up the development environment for Kindle Fire in Eclipse from the Amazon Site. Though I added the add-on URL in 'Manage Add-On Site' option correctly, still Android SDK Manager is not displaying the following options for downloading: Android 4.2.2 (API 17) SDK Platform ARM EABI v7a System Image Intel x86 Atom System Image Kindle Fire HD 7″ (3rd Generation) Kindle Fire HDX 7″ (3rd Generation) Kindle Fire HDX 8.9″ (3rd Generation) Now I am able to see only

问题 Is DEBUG == False supposed to mean that the app is running in production environment? At least, that's what I see occasionally on the internet. But what do I put in settings.py then? Okay, I can put local settings to, say, settings_local.py and import it from settings.py . But if some settings depend on environment, than I've got to put them after import statement. There more I think about it, the more I don't like it. And you? 回答1: As an answer to the question: Is DEBUG == False supposed to

问题 I have a library which I am currently developing with target compatibility to JDK 6. I like to take advantage of Java 8 feature, like lambdas. The code and APIs will greatly profit from Java 8. I would like to offer versions of the library for Java 6 and Java 8, e.g., where a certain part is only available in the Java 8 version. Now there are a few core classes which might have their different source version (the legacy Java 6 version and the new Java 8 version). What is the best practice of

问题 is it better to develop ruby on rails in a) windows b) linux or c) mac. why ? edited : the reason why i am asking this is that i heard that developing ruby on rails in windows is not as stable/good compared when you used ruby on rails in mac. (not sure though if that is true or not). plus the fact that David Heinemeier Hansson (creator of Ruby on Rails) seems to be using Mac, so initial impressions seems to be Ruby on Rails applications and Mac goes well together. 回答1: I strongly advise you

问题 Imagine you have your web application and some workflow executors: http-server (serving pre-build asset files) - production builder (compiling/bundling js/css/html from sources) - deployment/development debugger/builder (building from sources on the fly, add js source maps) - development selenium (running tests) - integration testing How can we construct layered images to get those workflow executors working the most effectively? By effectively I mean "fastest to run and least to write". 回答1:

问题 How is it possible that a core module is importing a non-existent name from another core module? Specifically, the re module importing enum.IntFlag Ways to Reproduce It can be reproduced by launching an interpreter and attempting the import, running a program that depends on enum.IntFlag such as pip , viewing the interpreter settings page in Eclipse, using the text editor, running the interactive console in PyDev, ... Directly importing from enum import IntFlag Traceback (most recent call
