G`MIC (GREYC`s Magic For Image Computing) Sees New Stable Release

G'MIC (GREYC's Magic for Image Computing) is a framework for image processing that comes with a large number of pre-defined image filters and effects (almost 400, with an extra 300 testing filters). There are several interfaces for G'MIC: a command line tool, a web service, a Qt based interface for real-time webcam manipulation, a library and a GIMP plugin.

Below you can see a screenshot with the G'MIC GIMP plugin in action:


Screensaver / Lock Screen Inhibitor `Caffeine Plus` Brings Back The Screensaver Toggle Option

Caffeine is a tool used to temporarily prevent the activation of the screensaver / lock screen / sleep mode when using full-screen windows. The application is useful when using video players that don't do this automatically, when listening to music while not using the computer, etc.

Caffeine Plus AppIndicator

The latest Caffeine version (2.7.x), released back in May, no longer comes with an Ubuntu AppIndicator so you can't manually toggle it on/off any more, feature which was considered pretty important by many of its users. If you're one of them, you can now use Caffeine Plus, a Caffeine 2.7 fork which restores the Ubuntu AppIndicator icon, allowing you to manually toggle it on/off.

Encrypt DNS Traffic In Ubuntu With DNSCrypt [PPA]

DNSCrypt is a protocol for securing communications between a client and a DNS resolver, preventing spying, spoofing or man-in-the-middle attacks. To use it, you'll need a tool called dnscrypt-proxy, which "can be used directly as your local resolver or as a DNS forwarder, authenticating requests using the DNSCrypt protocol and passing them to an upstream server".

I wrote about DNSCrypt before but some things have changed since then ( can't be used by DNSCrypt any more on Ubuntu because that's used by Ubuntu's local DNS cache, there are no Linux binaries available for download, etc.) so this is an update for Ubuntu users who want an easy way of installing / using it.

How To Enable HTML5 Playback For Netflix On Ubuntu 14.04 Or 14.10

Netflix supports HTML5 playback (using the Encrypted Media Extensions) but unfortunately, it doesn't work out of the box on Linux for now. However, following a few steps, you can get native Netflix HTML5 video playback through Google Chrome (Beta or Unstable at the time I'm writing this article) in Ubuntu 14.04 or 14.10.

Netflix HTML5 Ubuntu

The instructions below are for Ubuntu, but they should work on other Linux distributions as well, as long as you have a recent libnss3 version (tested with libnss3 and libnss3-1d version 3.16.3, libnss-db 2.2.3pre1 and Google Chrome 37 Beta under Ubuntu 14.04).

PPA Updates: Atraci 0.6.0, Atom 0.123.0, Brackets 0.42, GPaste 3.10.3 And 3.12.2, Minitube 2.2, Oracle JDK 7u67 And More

As you might have noticed, I was on holiday* until today and because of that, there were no new articles on WebUpd8 and no updates for the WebUpd8 PPAs. Today I updated the PPA packages for most applications that had a new release while I was away, and to speed things up, below you'll find a quick list with what was updated / what's new.

Pushbullet Indicator Gets Android Notification Mirroring Support, Other Changes

Pushbullet Indicator was updated recently with support for the latest Pushbullet API changes, which include OAuth support and notification mirroring from Android to your computer.

Pushbullet Indicator Ubuntu

For those not familiar with Pushbullet, this is a service that lets you easily send files, links, notes, lists, etc. from your iOS or Android device to your desktop or the other way around. It can be used via Chrome / Firefox extensions and for Windows there's also a desktop app. Because there was no native Linux app, Lorenzo from Atareao.es created an Ubuntu AppIndicator (and a Nautilus extension as a companion for the AppIndicator) to easily use Pushbullet in Ubuntu.
