Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.

This describes the steps required to configure multiple PHP versions on your development system, if you have issue using the AUR package. Normally one may install the AUR package on a custom path, .e.g, /usr/local/php, but if you are like me having some issues with that you might want to try a custom compile.

Pay attention to step 6) as this is where any required extensions are enabled. For this setup we generally need pdo and mysql extensions.

---

1. Download PHP version 5.3.13 (or any version that you are interested in) from http://php.net/releases/

2. Download the php53 AUR package from https://aur.archlinux.org/packages/php53/

Bamboo as a Systemd Service

Make Atlassian Bamboo start as a Systemd service on Linux (CentOS).

Add a new bamboo user and group as explained in the Atlassian's tutorial.

useradd --create-home -c "Bamboo role account" bamboo

Make sure the binary and home directories are owned by the new user:

Gradle Dependency Resolution

Normal Gradle behavior

The default behavior of Gradle to pick the newest version also applies if a lower version has been declared locally, but another dependency transitively pulls in a newer version. This is in contrast with Maven, where a locally declared version will always win.

For example, if your build.gradle specifies the dependency org.springframework:spring-tx:3.2.3.RELEASE, and another dependency declares 4.0.5.RELEASE as a transitive dependency, then 4.0.5.RELEASE will take precedence:

dependencies {
    compile("org.springframework.data:spring-data-hadoop:2.0.0.RELEASE")
    compile("org.springframework:spring-tx:3.2.3.RELEASE")

// will select org.springframework:spring-tx:4.0.5.RELEASE
