SnapRAID – Jupiter Broadcasting

OpenMediaVault is the next generation network attached storage (NAS) solution based on Debian Linux. It contains services like SSH, (S)FTP, SMB/CIFS, DAAP media server, RSync, BitTorrent client and many more. Thanks to the modular design of the framework it can be enhanced via plugins.

OpenMediaVault is primarily designed to be used in home environments or small home offices, but is not limited to those scenarios. It is a simple and easy to use out-of-the-box solution that will allow everyone to install and administrate a Network Attached Storage without deeper knowledge.

OpenMediaVault 3 Pros

Debian 8 is very secure and solid, around for a while.
I live in a systemd world.

OpenMediaVault Super Plugins:

Greyhole is worth the price of adition alone.
SnapRAID could give you real data protection.

How Greyhole Works

The user defines it’s storage pool by listing all the paths of the different disks he wants to use.
When files are added on Greyhole shares’ Landing Zones, the Greyhole daemon moves those files into 1+ of the paths defined as the storage pool. It then replaces the original file (on the share) by a symbolic link pointing to one of the copy created in the pool.
Samba is configured to use opaque symbolic links, i.e. what are in fact symbolic links in the shares appear as normal files to clients.

OpenMediaVault 3 Cons

Base system and plugins are still a moving target.
No UI to connect to external NFS shares, NFS mounts don’t show up in UI.
No built in UI to configure UPS support, plugin.
UPS (Uninterruptible Power Supply) plugin finished

Lenovo confirms that Linux won’t work on Yoga 900 and 900S laptops

Device maker Lenovo today issued a statement confirming that its Yoga 900 and 900S convertible laptops cannot boot Linux — only Windows 10.

“requires very specific, complex and unique drivers that require even greater amounts of testing, to ensure class-leading performance with Windows 10”.

“support our Yoga products and our industry-leading 360-hinge” before stating it “does not intentionally block customers using other operating systems”.

Lenovo: No, we didn’t plot with Microsoft to block Linux on our laptops

Compounding matters, a ‘Lenovo Product Expert’ seemingly responded to a Best Buy customer’s complaint online with the following:

“This system has a Signature Edition of Windows 10 Home installed. It is locked per our agreement with Microsoft.”

If Linux won’t install on your laptop, blame Intel not Microsoft

Here’s the problem: Linux doesn’t support internal solid-state drives in RAID (Intel RST) mode. Linux can see the drive in AHCI (Advanced Host Controller Interface) mode. However, certain Lenovo laptops don’t allow the mode to be changed in the BIOS. You can boot Linux from a USB drive, but not install it on the laptop’s SSD.

Hardware hack enables Linux support on Lenovo Yoga 900 ISK2, undermining Lenovo’s statement

A hardware hack has enabled AHCI support on the Lenovo Yoga 900 ISK2, undermining Lenovo and Microsoft’s claims that Linux is “missing drivers”.

Unfortunately, the procedure to flash the BIOS is too complicated for most people because the person who did it had to use external flashing equipment to bypass Lenovo’s ROM signature check and load the modified BIOS, and he can’t provide the BIOS ROM because it only supports his computer and has private info in it, such as the Windows 10 license for his machine.

Subject: Proper use of Touchpad

Message: Hello guys. My question may be silly but I am trying from a year and more to find a proper way to use and configure touchpad/clickpad on GNU/Linux. Could you suggest me some information online because I am looking in particular how to use it (position of hands), proper configuration under GNU/Linux (palm tracking, sensitivity, coasting, scrolling, etc)?

Subject: Wallpaper Changer

Message: Hi Chris.

I think it was in last weeks LAS that you were showing your desktop with the wallpaper changer app that took random wallpapers from an online source and set them for you. I like doing something similar because it is good to have variety. You said you are just collecting your favourite background images to a single folder so that you can cycle through them instead randomly grabbing from an online source.

Because wallpaper slideshows do not seem to be baked in to the GNOME DE and I cannot find a wallpaper changer that I like I am instead using a script which I keep running in the background to change my wallpaper every 10 minutes. I don’t know if I already shared it with you but here is my script for changing wallpapers.

#!/bin/bash
WP_DIR="/home/drthpnguin/Dropbox/Wallpapers/HD-Wallpapers"
cd "$WP_DIR"
while [ 1 ] 
  do
  set -- * 
  length=$#
  random_num=$((( $RANDOM % ($length) ) + 1)) 
  gsettings set org.gnome.desktop.background picture-uri "file://$WP_DIR/${!random_num}"
  sleep 600
done

Qubes OS:

Brought to you by: System76

Qubes Release 1 was released in September 2012. Qubes Release 2 is almost complete, with rc1 having been released in April 201
On February 16, 2014, Qubes was selected as a finalist of Access Innovation Prize 2014 for Endpoint Security Solution.

Built on top of Xen:

Qubes is based on Xen, the X Window System, and Linux, and can run most Linux applications and utilize most of the Linux drivers.

Qubes implements a Security by Isolation approach.
Qubes utilizes virtualization technology in order to isolate various programs from each other and even to sandbox many system-level components, such as networking and storage subsystems, so that the compromise of any of these programs or components does not affect the integrity of the rest of the system.
Qubes lets the user define many security domains, which are implemented as lightweight Virtual Machines (VMs), or “AppVMs.”

For example, the user can have “personal,” “work,” “shopping,” “bank,” and “random” AppVMs and can use the applications within those VMs just as if they were executing on the local machine. At the same time, however, these applications are well isolated from each other.

Qubes also supports secure copy-and-paste and file sharing between the AppVMs, of course.

Key Architectural features¶

The network mechanism is the most exposed to security attacks. This is why it is isolated in a separate, unprivileged virtual machine, called the Network Domain.
Disk space is saved thanks to the fact that various virtual machines (VM) share the same root file system in a read-only mode.
Separate disk storage is only used for userʼs directory and per-VM settings. This allows to centralize software installation and updates. Of course, some software can be installed only on a specific VM.
Some documents or application can be run in disposable VMs through an action available in the file manager. The mechanism follows the idea of sandboxes: after viewing the document or application, then the whole Disposable VM will be destroyed.

Based on a secure bare-metal hypervisor (Xen)
USB stacks and drivers sand-boxed in an unprivileged VM (currently experimental feature)
No networking code in the privileged domain (dom0)
All user applications run in “AppVMs,” lightweight VMs based on Linux
Centralized updates of all AppVMs based on the same template
Qubes GUI virtualization presents applications as if they were running locally
Qubes GUI provides isolation between apps sharing the same desktop
Secure system boot based (optional)

Not just for Linux, Qubes can run Windows app seamless too:

SnapRAID

SnapRAID is an application able to make a partial backup of your disk array. If some of the disks of your array fail, even if they are completely broken, you will be able to recover their content. It’s only a partial backup, because it doesn’t allow to recover from a failure of the whole array, but only if the number of failed disks are under a predefined limit.

Basically, magpie is just a web tool for managing text files in a git repo. In it, you can create notebooks (which are just folders); create, edit, and delete notes (which are just files). That’s pretty much it. However, when you make any of these changes, they are automatically committed to git.

It’s Here: Docker 1.0

On March 20, 2013, we released the first version of Docker. After 15 months, 8,741 commits from more than 460 contributors, 2.75 million downloads, over 14,000 “Dockerized” apps, and feedback from 10s of 1000s of users about their experience with Docker, from a single container on a laptop to 1000s in production in the cloud … we’re excited to announce that it’s here: Docker 1.0.

HP bets it all on The Machine, a new computer architecture based on memristors and silicon photonics

In the words of HP Labs, The Machine will be a complete replacement for current computer system architectures. There will be a new operating system, a new type of memory (memristors), and super-fast buses/peripheral interconnects (photonics). Speaking to Bloomberg, HP says it will commercialize The Machine within a few years, “or fall on its face trying.”

Day 2 Keynote – HP Discover Las Vegas 2014 – tStarts at 15:50

Some of our favorite bullshit headlines:

On top of that, HP is working on a brand new operating system for The Machine based on Linux. And another one based on Android, Fink continued:

“We are, as part of The Machine, announcing our intent to build a new operating system all open source from the ground up, optimized for non-volatile memory systems.

…

We also have a team that’s starting from a Linux environment and stripping out all the bits we don’t need. So that way you maintain … compatibility for apps.

What if we build a version of Android? … We have a team that’s doing that, too.”
