version

I'd like to use .NET in some PowerShell scripts I'm about to write -- how do I know/declare which version of .NET I'm dealing with when these scripts run? And is it possible to choose against which version of .NET my script will run? On PowerShell 2.0, just take a peek at the $PSVersionTable variable: PS> $psversiontable Name Value ---- ----- CLRVersion 2.0.50727.4927 BuildVersion 6.1.7600.16385 PSVersion 2.0 WSManStackVersion 2.0 PSCompatibleVersions {1.0, 2.0} SerializationVersion 1.1.0.1 PSRemotingProtocolVersion 2.1 On PowerShell 1.0, use [System.Environment]::Version : PS> [Environment]:

I have run into a bug with gcc v3.4.4 and which to put an #ifdef in my code to work around the bug for only that version of the compiler. What are the GCC compiler preprocessor predefined macros to detect the version number of the compiler? DigitalRoss From the gnu cpp manual... __GNUC__ __GNUC_MINOR__ __GNUC_PATCHLEVEL__ These macros are defined by all GNU compilers that use the C preprocessor: C, C++, Objective-C and Fortran. Their values are the major version, minor version, and patch level of the compiler, as integer constants. For example, GCC 3.2.1 will define __GNUC__ to 3, __GNUC_MINOR

Is it possible to have different versions of NodeJS installed on the same machine? There are several node managers which you can use to achieve this, but the most popular are: NVM n I use nave. https://github.com/isaacs/nave > npm install -g nave > nave use 0.4.12 # starts a subshell with 0.4.12 at the head of the path > node --version v0.4.12 > exit # go back to the original shell > nave use 0.6.5 > node --version v0.6.5 > nave usemain Note that the first time you need a version, it will be downloaded and compiled for you. If you need something simple, the n utility is just for you. Install

Currently I am using JPA 2.0 with hibernate 3.6 . I tried to search but couldn't find, can anyone list out JPA 2.1 is supported by which versions of hibernate? Boris Pavlović According to Hibernate's versions list , JPA 2.1 is going to be supported by version 4.3 or by 5.0 Josh Hibernate 4.3.0.Final (Dec. 16, 2013) is the first production ready release to support jpa 2.1. See: http://in.relation.to/Bloggers/HibernateORM430FinalRelease The main focus of 4.3 was JPA 2.1 support, so much of the work these past few months focused on new JPA 2.1 features. ThanksForAllTheFish Boris is right though

I would like to use some gcc warning switchs that aren't available in older gcc versions (eg. -Wtype-limits). Is there an easy way to check the gcc version and only add those extra options if a recent gcc is used ? I wouldn't say its easy, but you can use the shell function of GNU make to execute a shell command like gcc --version and then use the ifeq conditional expression to check the version number and set your CFLAGS variable appropriately. Here's a quick example makefile: CC = gcc GCCVERSION = $(shell gcc --version | grep ^gcc | sed 's/^.* //g') CFLAGS = -g ifeq "$(GCCVERSION)" "4.4.3"

I've been trying to find a parser or regex that will give me the Android OS version from a user agent string. E.g. Mozilla/5.0 (Linux; U; Android 2.2.1; fr-fr; Desire HD Build/FRG83D) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1 Will return: 2.2.1 Can anyone help? fearphage This regular expression is a bit more "future proof" than mathepic's answer : Android (\d+(?:\.\d+)+); It allows for multiple digits in each place as well as additional periods in the version number. Android's been out 3 years and we're on 3.0. Eventually we'll get to 10.0.0. This will catch all of

How to translate MS Windows OS version numbers into product names? For example, in .NET the following two properties could be used to work out that the product is MS Windows Vista Ultimate Edition : Environment.OSVersion.Platform returns Win32NT Environment.OSVersion.Version returns 6.0.6001.65536 Avram howto net os version VB: Public Function GetOSVersion() As String Select Case Environment.OSVersion.Platform Case PlatformID.Win32S Return "Win 3.1" Case PlatformID.Win32Windows Select Case Environment.OSVersion.Version.Minor Case 0 Return "Win95" Case 10 Return "Win98" Case 90 Return "WinME"
