versions

问题 On my system, I have several modules installed multiple times. To give an example, numpy 1.6.1 is installed in the standard path at /usr/lib/python2.7/dist-packages , and I have an updated version of numpy 1.8.0 installed at /local/python/lib/python2.7/site-packages/ . The reason I cannot simply remove the old version is that I do not have permissions to change anything on my work computer. I however need to use the new numpy version. I have added /local/python/lib/python2.7/site-packages/ to

问题 I want to write a little app for myself which notifies me if there is a new version of php or mysql but I would need a feed or an xml file to read it from. 回答1: PHP.net provides one http://www.php.net/releases/index.php?serialize=1 An alternative that may allow you to add additional software later is looking into the feeds provided by freshmeat: http://freshmeat.net/projects/mysql/ 回答2: You could probably subscribe to www.freshmeat.net's rss feed and only react when an even numbered version

问题 This is in reference to a warning message appearing in build.gradle file: All com.android.support libraries must use the exact same version specification (mixing versions may lead to runtime crashes) I'm well aware of this and use identical versions in my own code / build. However this isn't the case when it comes to some 3rd party libraries that I use. Sometimes 3rd party libraries use older versions, and some other ones use newer versions - so updating your version of support libraries will

问题 I'm working on a google app engine app that, after a lot of progress, has multiple versions deployed. I'd really like to switch the default version, which is the very first version of the app, to something more recent, but there doesn't seem to be any way to actually do that. This article https://gae-php-tips.appspot.com/2013/06/25/harnessing-the-power-of-versions-on-app-engine/ claims there is a "Make Default" button under the version tab, but shows an older version of the console. In the

问题 I want to list all of the applications and versions installed on my mac. Stuff like perl, php, etc., not the stuff you see in the Applications directory... Is there a unix command for that? 回答1: Not exactly a unix command but: system_profiler -detailLevel full > myreport.txt might be a good start. There's an option to only list software (as there is an option to ouput xml) (read the manpage for the precise syntax). If you're using macports you could just run port installed . 回答2: pkgutil -

问题 I've modified a couple of different applications' .config file like this: <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> When I did this for devenv.exe.config (VS 2005 - don't ask :) ), things work great - most of the Visual Studio used .NET 2.0 but I was able to make use of an assembly targeting .NET 4.0 framework. I tried to do the same thing for a custom .exe, which happens to be based on MS CAB (slightly modified) and has a hybrid mix of

问题 Where I can find a comparative speed benchmark between python versions? For example the performance between 2.6, 2.7, 3.0 , 3.1 and 3.2 versions. 回答1: Pystone benchmark on 2.6,2.7,3.2: http://www.levigross.com/post/2340736877/pystone-benchmark-on-2-6-2-7-3-2 (3.0 and 3.1 are probably slower than 3.2) 回答2: There is a Python module with various real-world performance tasks to measure different builds / versions of Python - performance. You can install it with the following command: pip install

问题 I am developing an application in Qt, but using D language (with QtD binding). I've noticed that my app crashes with Qt 4.7.x, so I need to use Qt 4.6.2 instead. However in my system Qt 4.7.2 is installed. Unfortunately I neither make QtD work with the latest Qt versions nor (I'm afraid) count on QtD developers... The only thing I need to make my application install in system Qt 4.6.2 libs and use it, but let all the other applications still use Qt 4.7.2. Is it possible? If it is, how to do

问题 I'm new to Rails...using RubyMine as an IDE. I have Paper_Trail saving previous versions of the data "xoi_qb". My view is currently showing the current and previous data as I'd like, but I would like to show the diff between the current version "xoi_qb" and the previous version "xoi_qb". For instance, the current version may be "97" and the previous version may be "94", and I would like to display "XOI +/-: +3". I would like to display this difference and add the "+" or "-" based on the
