Khronos, Mesa, Standards & Conformance / Certification: Open Source, Open Standards

Phoronix - Sat, 2016-10-15 15:10
The past week or two in our forums and elsewhere there's been a lot of comments about Khronos' conformance testing for OpenGL 4.4/4.5 with the Mesa drivers finally reaching that point, concern over Khronos' fees being prohibitive for open-source projects (particularly in cases like Nouveau where it's community driven without a main corporate backer), and some FUD related to this matter. I've now received some clarification from The Khronos Group to lay these concerns to rest...

Searching for good resources regarding cloud architecture

Reddit - Sat, 2016-10-15 14:31

I recently started a new job as an junior server admin in the cloud (~150 nodes with CentOS). I realised there is much to learn and I am willing. I was wondering maybe you guys can help me with some good resources (books, video, websites, etc..) that will enlighten my understanding. I think i have fair knowledge about individual components, but I fall short when pieces are connected together - architecture, (infrastructure?), topology, optimisation (the key term) and security.

The technology we use: load-balancing (haproxy), nginx, apache, MariaDB, Redis, Elastic-search, etc. All nodes are managed via salt (Salt Stack).

I know OSX != Linux, but thought someone here might know how to solve this

Reddit - Sat, 2016-10-15 09:01

So I'm running OSX 10.11.6, and trying to write a simple simple shell script to periodically dd an image of my hard drive to an external USB drive.

(This hard drive used to hold a time machine backup)

But dd can't run - I get an error stating:

d: /dev/disk4s2: Resource busy

I DDGed around and it looks like I need to unmount the drive first. Sounds simple. However OSX likes to do things its own way which has sent me down a rabbit hole...

Firs my system doesn't seem to have disktutil installed. Here's what happens when I try to locate the partition in use and unmount it:

$ clear; diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.3 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage Macintosh HD 499.4 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk1 (internal, virtual): #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD +499.1 GB disk1 Logical Volume on disk0s2 B57C7D76-588A-422A-902D-9BAAD39192EC Unlocked Encrypted /dev/disk2 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme +19.7 MB disk2 1: Apple_partition_map 32.3 KB disk2s1 2: Apple_HFS Flash Player 19.6 MB disk2s2 /dev/disk3 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme +19.7 MB disk3 1: Apple_partition_map 32.3 KB disk3s1 2: Apple_HFS Flash Player 19.7 MB disk3s2 /dev/disk4 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk4 1: EFI EFI 209.7 MB disk4s1 2: Apple_HFS BACKUP 499.8 GB disk4s2 $ disktutil unmount /dev/disk4s2 -bash: disktutil: command not found

I DDGed some more, someone suggested running it w/ sudo. No luck. Another suggested that OSX puts diskutil in /usr/bin/, but I don't see it there:

$ ls /usr/bin/ | grep disk diskhits $ sudo ls /usr/bin | grep disk diskhits

So TL;DR: How can I zero a drive using DD in OSX? Is there some similar tool to diskutil on OSX?

Raspbian Question: How can I schedule a script to run after the desktop environment is fully up? [x-post /r/raspberry_pi]

Reddit - Sat, 2016-10-15 05:52

Greetings. As the title indicates, I'm having trouble triggering a script on the Raspberry Pi 3 Model B running Raspbian. I've tried setting up a CRON job @reboot, but the problem with that is that since the script involves a GUI element, it doesn't run correctly because the Display Manager isn't up when the CRON job runs. I've tried adding a delay to the CRON job [ @reboot sleep 15 && /usr/bin/tscript.sh ] but that seems to have no effect. I've also tried writing a C program that uses the system() function to call what I need to call, and then adding that executable to rc.d (and init.d), but that doesn't work either. What am I doing wrong?
