We document a bash script for Redis SCAN, which tries not to overwhelm our production system. This is useful for pruning, migrating keys, archiving content to disk e.g. into a pre-cache to be served directly by Nginx try_files
LimeSurvey is one of the many open source survey applications written in PHP, and uses a MySQL or PostgreSQL database. LimeSurvey is a user-friendly web application that allows users to develop, publish and collect responses to surveys. Users can use rich text in questions and messages using a rich text editor, and images and videos can easily be integrated into surveys. Surveys can be public, or can be strictly controlled through the use of ‘once-only’ tokens for each survey participant.

CRISPR-Cas can be thought of as the first really powerful and general-purpose genome editor -- a GNU Emacs for DNA. It is widely expected that it will have a massive impact on molecular biology, both for pure research and in industrial applications. Given those very high stakes, it will not come as a surprise to learn that there is already a fierce tussle over who owns a key patent in this field:

CAINE 7.0 'DeepSpace' is out. Changelog: Linux kernel 3.13; based on Ubuntu 14.04.1 64-bit, UEFI and Secure Boot ready; SystemBack is the installer. The important news is that CAINE 7.0 blocks all the block devices (e.g. /dev/sda), in read-only mode. You can use a tool with a GUI named BlockOn/Off present on Caine's desktop. This new write blocking method assures that all disks are really preserved from accidentally writing operations, because they are locked in read-only mode. If you need to write to a disk, you can unlock it with BlockOn/Off or by using 'Mounter' to change the policy. Another important news is the addition of the VNC server and client for controlling CAINE from a remote location. CAINE now boots faster and it can boot to RAM.
