how I resolved nrpe configure: error: C preprocessor /lib/cpp fails sanity check

rpm -qa | grep glibc

see all glibc installations

for example, on a problem machine I found:

glibc-2.12-1.80.el6_3.5.i686
glibc-2.12-1.80.el6_3.5.x86_64
glibc-common-2.12-1.132.el6_5.2.x86_64
glibc-devel-2.12-1.132.el6_5.2.x86_64
glibc-common-2.12-1.80.el6_3.5.x86_64
glibc-2.12-1.132.el6_5.2.x86_64

yum erase glibc\*

install headers

yum install glibc-headers.x86_64 0:2.12-1.132.el6_5.2

fixed

#!/bin/bash - no such file or directory

This can be cause by an extra carriage return at the end of the first line

execute the following in termial:

head -1 yourscript | od -c

if it ends with \r \n then it is not in the correct format.

if it ends with \n with no \r preceding that, then it is correct.

to fix the file, use dos2linux

sudo apt-get install dos2linux

dos2linux yourscript

remove hidden files that show on desktop in osx

Sometimes its good to see hidden files in finder, but its annoying that they show up on the desktop.

If you want to stop these showing, here is the command to run in terminal:

defaults write com.apple.finder CreateDesktop -bool false && killall Finder

to make them appear again, use:

defaults write com.apple.finder CreateDesktop -bool true && killall Finder

Windows vcvarsall problem

This is taken from: stackoverflow answer: building-lxml-for-python-2-7-on-windows

There's def find_vcvarsall(version): function (guess what, it looks for vcvarsall.bat) in distutils with the following comment

At first it tries to find the productdir of VS 2008 in the registry. If that fails it falls back to the VS90COMNTOOLS env var.

If you're not using VS 2008 then you have neither the registry key nor suitable environment variable and that's why distutils can't find vcvarsall.bat file. It does not check if the bat file is reachable through the PATH environment variable.

The solution is to define VS90COMNTOOLS variable to point to Tools directory of Visual Studio.

That being said take a look at 11.4. distutils.msvccompiler — Microsoft Compiler section in Python's docs which states

Typically, extension modules need to be compiled with the same compiler that was used to compile Python.

Martin v. Loewis in the email titled Download Visual Studio Express 2008 now on python-list mailing list states the same

Python 2.6, 2.7, and 3.1 are all built with that release (i.e. 2008). Because of another long tradition, Python extension modules must be built with the same compiler version (more specifically, CRT version) as Python itself. So to build extension modules for any of these releases, you need to have a copy of VS 2008 or VS 2008 Express.

SET VS90COMNTOOLS=%VS100COMNTOOLS%

install ruby 2.1 ubuntu

sudo apt-get install python-software-properties
sudo apt-add-repository ppa:brightbox/ruby-ng 

sudo apt-get update 

sudo apt-get install ruby2.1 

ruby2.1 -v 
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux-gnu]

using .ruby-version instead of .rvmrc

imagine you want to create a my ruby application called myrubyapp which will use ruby version 2.1.0

/bin/bash --login

rvm --create --ruby-version use ruby-2.1.0@myrubyapp


previously, you would have had a file .rvmrc, inside your myrubyapp dir, and in it would have been:

rvm use 2.1.0@myrubyapp


now, you would not create the .rvmrc file, and instead, create two files as follows: 

create a file named: .ruby-version:

in it, enter: 2.1.0

create a file named: .ruby-gemset:

in it, enter: myrubyapp

all done...

Convert wmv to mp4 for free

When you look around for solutions to this problem, you are usually met with either paid software, or free software bundled with spyware. When all along, there has been ffmpeg, an application that will convert most formats, and is freely available with a big community, and no spyware.

To convert an wmv to an mp4, heres what you need to do:

For Windows:

Download the ffmpeg application here:

http://ffmpeg.zeranoe.com/builds/ (pick 32 or 64 bit as required)

If you dont have 7zip, download it here 

http://www.7-zip.org/download.html

and install it.

Now extract the ffmpeg 7zip file. Now navigate in to the extracted directory and see a file called:

ff-prompt.bat

double click it to open the ffmpeg command prompt. With the command prompt open, type this command and press enter to begin the conversion:

ffmpeg -i c:\pathToInput.wmv -f mp4 -s 500x400 -strict -2  c:\pathToOutput.mp4

For Linux, do:

sudo apt-get install ffmpeg

open terminal, and run command:

ffmpeg -i /pathToInput.wmv -f mp4 -s 500x400 -strict -2  /pathToOutput.mp4
