I run a small hosting provider with more or less 1535 customers and I use Ansible to automate some operations to be run on all servers. Last night I accidentally ran, on all servers, a Bash script with a rm -rf {foo}/{bar} with those variables undefined due to a bug in the code above this line.
All servers got deleted and the offsite backups too because the remote storage was mounted just before by the same script (that is a backup maintenance script).
How I can recover from a rm -rf / now in a timely manner?
The fglrx driver is now deprecated in 16.04, and we recommend its open source alternatives (radeon and amdgpu). AMD put a lot of work into the drivers, and we backported kernel code from Linux 4.5 to provide a better experience.
When upgrading to Ubuntu 16.04 from a previous release, both the fglrx driver and the xorg.conf will be removed, so that the system is set to use either the amdgpu driver or the radeon driver (depending on the available hardware).
OpenSSL has classified this vulnerability as "low severity", which we agree with. In order to mount the attack, the attacker has to be able to run the attack code on the same machine that runs the victim code. CacheBleed is a complex attack and there are much easier-to-exploit vulnerabilities in personal computers that it is unlikely that anyone would use CacheBleed in such an environment.

UPDATE: This affects OpenSSH versions 5.4 through 7.1.
That is, add the option UseRoaming no to your /etc/ssh/ssh_config (or your user's ~/.ssh/config) file, or start your ssh client with -oUseRoaming=no included on the commandline.
We will be updating this article with more information as it becomes available.
By contrast, the OpenSSH bug can only be exploited after a vulnerable end user connects to a maliciously configured server.
OpenSSH could be made to expose sensitive information over the network.

Open-source Swift can be used on Linux to build Swift libraries and applications. The open-source binary builds provide the Swift compiler and standard library, Swift REPL and debugger (LLDB), and the core libraries, so one can to jump right in to Swift development.
