Way back in kernel 2.6, a new security system was introduced to provide a mechanism for supporting access control security policies. This system was Security Enhanced Linux (SELinux) and was introduced by the National Security Administration (NSA) to incorporate a strong Mandatory Access Control architecture into the subsystems of the Linux kernel.
If you’ve spent your entire Linux career either disabling or ignoring SELinux, this article is dedicated to you — an introduction to the system that lives “under the hood” of your Linux desktop or server to limit privilege or even eliminate the possibility of damage should programs or daemons become compromised.
Some MacBooks have two graphics cards, the specific one this post is about is a MacBookPro8,2 (15-inch, Late2011) with an Intel HD Graphics 3000 and an AMD Radeon HD 6750M.
If you boot any OS into legacy BIOS mode (only option supported by – at this time – most recent release version 5.8 of OpenBSD), it is always the Radeon card that gets activated (except for Windows OS, where Bootcamp/drivers should handle the automatic switching just like in Mac OS).
You need an external USB WLAN card (or something else, if you want network access), because the internal one is not supported by OpenBSD.
Android Wear gets wide Marshmallow rollout, adds speaker and LTE support
The Android 6.0 Marshmallow update for Android Wear is back. The update debuted on the disastrous LG Watch Urbane 2nd Edition LTE in November, but due to "image quality issues," LG pulled the watch from the market after only six days. The Marshmallow Android Wear update seemed to go down with the Watch Urbane, and the update went missing in action for the last two months. According to a post on the Official Android Blog, it's now back and will now roll out to "all Android Wear watches over the next few weeks."
