Learning The Linux File System
Before we get started, let’s avoid any confusion. There are two meanings to the term “File System” in the wonderful world of computing: First, there is the system of files and the directory structure that all of your data is stored in. Second, is the format scheme that is used to write data on mass storage devices like hard drives and SSD’s. We are going to be talking about the first kind of file system here because the average user will interact with his or her file system every time they use a computer, the format that data is written in on their storage devices is usually of little concern to them. The many different file systems that can be used on storage is really only interesting to hardware geeks and is best saved for another discussion. Now that that’s cleared up, we can press on.
Back to Computing 101
A computer file is a block of discrete information generated by a computer program and saved to a long-term storage device for retrieval later. In Linux, everything is a file. Even the devices hooked to your computer are represented as files. The novice computer user can usually identify some files because there are many standard formats. Files with the .mp3 extension are automatically associated with audio that is encoded in mp3 format, for instance. (Read the rest at Freedom Penguin)
MyPaint Fills a Graphics Void on Linux
When you think of Linux and graphic art tools, you probably consider Gimp or Blender to be the only available software. With that thought, you’d be very wrong. Yes, Gimp and Blender are the de facto standard tools for either image manipulation (Gimp) or Blender (3D graphics and animation), but what if you need a tool to create images from scratch?
Naturally, a program like MyPaint requires a certain skillset. Just because you are a master of Gimp, doesn’t mean you’ll run MyPaint and start creating masterpieces. With an application like MyPaint, you really need drawing/painting skills in order get the most out of the tool. you will also need a pressure-sensitive graphics tablet—as neither a mouse nor a trackpad is up to the task at hand.
The basic features of MyPaint are:
-
Available for Windows and GNU/Linux
-
Designed for pressure-sensitive graphics tablets
-
Simple and minimalistic user interface
-
Extensive brush creation and configuration options
-
Unlimited canvas (you never have to resize)
-
Basic layer support
Where MyPaint truly excels is in the area of the brush collection. Not only does MyPaint already offer an outstanding (and very usable) set of brushes, it includes an amazingly simple brush import tool (more on that later).
With that said, let’s install MyPaint on Elementary OS Freya and kick the tires.
Installation
Many standard repositories contain the stable version of MyPaint. However, I would suggest installing from the testing PPA (which is a rolling release PPA), so you are getting the most recent fixes and features.
If you want to install from that PPA, here are the steps:
-
Open up a terminal window
-
Add the PPA with the command sudo apt-add-repository ppa:achadwick/mypaint-testing
-
Update apt with the command sudo apt-get update
-
Install MyPaint with the command sudo apt-get install mypaint mypaint-data-extras
You should now see MyPaint within your distribution’s desktop menu. Plug in your pressure-sensitive graphics tablet (I use a Wacom Bamboo) and prepare to be impressed with what the software offers.
Usage
When you open up MyPaint, the first thing you should notice is the simplistic interface (see Figure 1 above).
The developers/designers of MyPaint did an outstanding job of keeping the interface out of the way. You can easily select your brush from the either the menu bar or the toolbar. But what happens when you want to adjust a brush, work with layers, or even see a preview? For that you have to open the various available panels. These panels appear in the right side of the main window and allow you to either adjust various elements or see a small-scale preview of your working drawing.
To add one of the panels, click Window and then select which panel you want. If you work a lot with layers, you might want to include the layer panel (Figure 2).


You can add layers in MyPaint in similar fashion to that of Gimp. You can:
-
Add a layer
-
Select the layer mode
-
Lock a layer
-
Hide a layer
-
Adjust the layer opacity
-
Move/copy/delete layers
-
Rename layers
Brushes
Of all the tools MyPaint has to offer, it’s the brushes that make or break the software. In this case, they definitely make it. If you click on Window > Brush Groups you’ll see seven different brush groups. Select from one of those groups and that brush group panel will appear in the right side of the window (Figure 3).
Once you’ve added a brush group panel, you can then select from the many brushes available to that group. Or, if you want to fine-tune a particular brush, you can click Window > Brush Settings Editor. When this window opens (it’s not a panel), you can go through every setting of a particular brush and make adjustments (Figure 4).

But, what if you don’t find the brush you’re looking for? Fortunately, the developers have included a brush import tool. To import a new brush pack, click Brush > Get More Brushes and your browser will open to a page where there is a small selection of available brushes. Locate the brush pack you want and do the following:
-
Download the zip file for the brush pack
-
Go back to MyPaint
-
Click on Brush > Import Brushes
-
Locate and select the downloaded zip file in your file manager
-
Click Open (in your file manager)
-
When prompted, okay the installation (Figure 5)
To open the new brush pack, click Window > Brush Groups, and select it from the list.
Canvas
As mentioned in the feature list, MyPaint includes an unlimited canvas. This means that you don’t have to guess the size of the image you are about to create. Every image begins with an infinite canvas. But, what do you do when you need to move the canvas around (to work on other parts of your drawing)? If your graphics tablet pencil has a control button, you can press that and then move the canvas about as needed. If you can’t get the hang of that, you can always use your mouse by pressing and holding the middle mouse button (scroll wheel) and moving the canvas around as needed.
To make these actions even easier, MyPaint also allows you to zoom in and out of the canvas. This way you can zoom out to see the entire image, position it such that the portion you want to work on is centered, and then zoom back in.

Scratchpad
A really handy tool called the Scratchpad Panel lets you select a brush, test it on the scratchpad, and then use it on your image. This approach will prevent you from mistakenly using the wrong brush on your work and having to undo the mistake. You can even save scratch pads (if you come up with an idea and want to use it later) by clicking the Save button in the Scratchpad Panel (Figure 6), or by clicking Scratchpad > Save Scratchpad.
If you’re looking for the missing piece to the graphics art puzzle in Linux, MyPaint will do an outstanding job of lining up with Gimp and Blender as your go-to tools for the creation of your masterpieces. Install it and give it a try and see if it stands up to your needs and talents.
Google Wants to Speed Up the Mobile Web with AMP Project
Google has a plan to speed up mobile Web browsing. The recently unveiled AMP—Accelerated Mobile Pages—project is an open source initiative that restricts certain elements of HTML, CSS, and JavaScript to produce leaner Web pages “that are optimised to load instantly on mobile devices.” How much quicker is “instantly”? According to Google, early testing with with a simulated 3G connection and a simulated Nexus 5 showed improvements of between 15 to 85 percent.
It’s all very clever, but at the same time very simple. “AMP HTML,” which sits at the core of the idea, wants to do things like minimize HTTP requests to fully lay out a document and only downloads images when they’re likely to be seen. There is a trade-off, however.

ICANN: Just Give Us the Keys to the Internet – Or the Web Will Disintegrate
Domain system overseer ICANN has embarked on a campaign of fear and fuzzy logic in its latest bid to seize control of the internet from the US government without agreeing to limits on its power.
The handover of the critical IANA functions from Uncle Sam to ICANN was due to happen last week, but has been set back a year to October 1, 2016 following procedural delays and extensive negotiations.
Now, ICANN warns, unless the internet community makes concessions on the controls that it wants to place on the organization’s Board, the process could take even longer – and that could lead to the end of ICANN itself, as well as the United Nations taking over the internet.

Matthew Garrett Is Not Forking Linux
But the famed Linux developer is putting his security work into his own Linux tree without Linus Torvalds’ approval. When Matthew Garrett, well-known Linux kernel developer and ‎CoreOSprincipal security engineer, announced he was releasing a [Linux] kernel tree with patches that implement a BSD-style securelevel interface, I predicted people would say Garrett was forking Linux. I was right. They have. But, that’s not what Garrett is doing. …
He’s building his own kernel tree because “The securelevel feature is part of the work done to make Secure Boot meaningfully useful – verifying that you’re booting a signed kernel isn’t terribly useful if it’s then straightforward for that kernel to be modified at runtime.”
