After a knock-out 2017, 2018 promises to be a big year for Linux. In this post we share 8 Linux predictions for the coming year, ranging from the possible to the improbable.
(Dec 29) Multiple security issues have been found in Thunderbird, which may lead to the execution of arbitrary code, denial of service, information disclosure or spoofing of sender’s email addresses.
(Dec 30) Multiple vulnerabilities have been discovered in Asterisk, an open source PBX and telephony toolkit, which may result in denial of service, information disclosure and potentially the execution of arbitrary code.
(Dec 30) Several vulnerabilities were discovered in GIMP, the GNU Image Manipulation Program, which could result in denial of service (application crash) or potentially the execution of arbitrary code if malformed files are opened.
Spotify is now available as a Snap app on Ubuntu and other Snap-supporting Linux distributions. The package means it’s now more convenient for fans of Spotify to install the official client on Ubuntu desktops as no external downloads or repo commands are required. Of course, the hugely popular music streaming service is no stranger to […]
Showing reference images for painting is a somewhat common feature request by GIMP users. While a specifically designed solution surely wouldn’t come amiss, there a simple way to work around this. Here is how you can do it with pretty much any version of GIMP from at least the past 10+ years.
Let’s take the default setup of GIMP (2.8 or 2.9 at your preference) with single-window mode enabled. Create an image where you will be painting, and then open an image that will be your reference.
Use Windows > Dockable Dialogs > Navigation to open the Navigation window:
By default, it will be added to the sidebar:
Now grab its header and drag it outside the sidebar:
Once it’s not docked anymore, it has a new option in its own menu: Show Image Selection (it’s been there since the time when dinosaurs ruled the world). Enable this option by clicking the triangle button (top right corner, below the Auto button) to open window’s menu.
Now you have a drop-down list of currently opened images and an Auto button. The button is enabled by default so that the Navigation window would follow currently opened image. Click it to disable autofollowing of images, then choose your reference image in the drop-down list.
Then you can resize the Navigation to your liking and start painting. If the Navigation window doesn’t stay on top (depends on operating system and window managers), one way to fix this is to go to Edit > Preferences > Window Management and choose Keep Above for Window Manager Hints.
There are several limitation with this workaround. First of all, it only works when the Navigation window is floating. It means that it inevitably overlaps part of your canvas, so it would be desirable to have this image selection drop-down list when the Navigation window is docked in the sidebar.
Secondly, since the Navigation window wasn’t designed for this purpose, you can’t zoom and pan your reference image.
And finally, once you use the Navigation window to view your reference image, you lose the ability to use it to pan and zoom on your painting. If this is how you usually pan images, there is a workaround for this.
When the scrollbars are enabled, their intersection in the lower right corner of the canvas has its own hidden navigation widget with the same arrowhead icon. Just click the arrowhead and start panning.
There are, however, other ways to pan and zoom:
You can also remap any shortcuts in GIMP and even customize it to use mouse wheel scroll to zoom in/out without pressing Ctrl: go to Edit > Preferences > Input Controllers, then edit Main Mouse Wheel controller settings.
(Dec 28) This update fixes several vulnerabilities in imagemagick: Various memory handling problems and cases of missing or incomplete input sanitising may result in denial of service, memory disclosure or the execution of arbitrary code if malformed image files are processed.
Ubuntu was more popular than Britney Spears, Linux Mint, and the Amazon Echo in 2017 according to the number of searches made using Google.

“Today i finally recognized that unit tests are a critical part of my programming flow” — Ashley Williams, Twitter.
Long-time Node.js advocate Ashley Williams kicked off her recent Twitter thread in the same sort of stream of consciousness that many devs go through when they are coming to terms with the truth: Unit testing is annoying but necessary.
I’m going to walk you through a few of the pieces involved in net-booting a Raspberry Pi and then talk about the challenges of running cloud native apps on a net-booted RPi.
It’s undeniable – Raspberry Pis capture the imagination of techies of all ages. Combine several Raspberry Pis into a cluster and you now have an x10 or x100 multiplier, but there are some problems with SD Cards. Netbooting is meant to fix this – but there are some limitations to its usefulness.
