Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

# Windows (receiver) side:
.\ffplay.exe -nodisp -ac 2 -acodec pcm_u8 -ar 48000 -analyzeduration 0 -probesize 32 -f u8 -i udp://0.0.0.0:18181?listen=1

  UPDATED for 2023 - Now much simpler. The old tricks are no longer needed.

  The following code makes an 800×600 canvas that is always as sharp as possible for the device.

  You still draw on it as if it's the logical size (800×600 in this case), but everything just
  looks sharper on high-DPI screens. Regular non-sharp screens are not affected.

Two way iframe communication

The main difference between the two pages is the method of sending messages. Recieving messages is the same in both.

Parent

SonarQube does currently not support Raspberry PI. 

This is a workaround. It compiles a armv6 compatible version of the java-wrapper and configures sonarqube to use it. 

(Testet with Raspbian, wheezy, 3.6)

Compile java-wrapper for ARMv6
============================
Download latest version of " wrapper_prerelease_XY.tar" from http://wrapper.tanukisoftware.com/downloads/ (for me 3.5.17 works)

For symmetic encryption, you can use the following:

To encrypt:
openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:
openssl aes-256-cbc -salt -a -d -in encrypted.txt -out plaintext.txt


For Asymmetric encryption you must first generate your private key and extract the public key.
