Wildfire Games has released 0 A.D. alpha 19 "Syllepsis" yesterday. This alpha release includes new gameplay features, graphics and user interface changes as well as various under the hood improvements.
0 A.D. is a historical war and economy game that runs on Linux, Windows and Mac OS X, which features several ancient civilizations, from Greece and Rome to Carthage and Persia.
The game comes with both singleplayer and multiplayer modes, and while there's no central server, players can use a lobby to discover other players and set up a game, or they can directly connect to each other using their IP addresses.
Changes in 0 A.D. alpha 19:
- non-siege units can now capture buildings and siege engines;
- new victory modes: "Conquest Structures" (destroy or capture all enemy structures to win) and "Conquest Units" (destroy all enemy units to win);
- ceasefire game mode: the game can be set so that all players are completely unable to attack their enemies for a predetermined time at the start of a game;
- attack coordination: players can request allies (including bots) to attack a specific enemy by clicking a button next to the player name in the diplomacy window. Also, Petra AI now supports attack coordination;
- Petra AI now warns its allies when it needs a tribute and lets them know when it advances to a new phase;
- the Ptolemaic lighthouse now has its special feature implemented: it reveals the shore on the entire map;
- new skirmish maps: Tuscan Acropolis (for 4 players; map preview), Northern Island (for 2 players; map preview), and Alpine Mountains (for 3 players; map preview);
- Graphics and UI:
- increased maximum map height: the engine now supports an eight times greater range of terrain heights, allowing for the creation of maps with more diverse and impressive landscapes;
- visual replay: re-run a game and understand what took place in real time;
- aura visualization: units affected by an aura are now marked with an icon when the aura giver is selected;
- new animals: new mastiff and wolfhound units have been added as well as a new rhinoceros;
- the Roman units now have voices in Latin;
- Other changes:
- new pathfinder: The pathfinder is the component of the game engine that picks a route for a unit to move along from its current location to its target location, so that it does not collide with other units or with structures or with impassable terrain. The new pathfinder improves performance, but at the same time, it also introduces some new bugs;
- XML validation: In 0 A.D., the behavior of units, buildings and other world objects is defined by their components, such as cost, health and more. All of these are described in XML files. The "grammar" of the XML files is now checked for correctness before being used by the game engine, which helps prevent technical problems;
- the generic Hellenic and Celtic factions have been removed;
- SDL2 is now enabled by default on Linux.
Below you'll find a video which presents some of these changes:

0 A.D. has low system requirements - on Linux, you'll need at least 512 MB of RAM, 1 GHz Intel or x86 compatible CPU and any graphics card that supports OpenGL 1.3 with 3D hardware accelerated drivers and at least 128 MB memory, e.g., Radeon 9000, GeForce 3, or similar.
If you can contribute to 0 A.D. (programming, art, sound, documentation and more), see the programmers getting started page and join #0ad-dev on QuakeNet on IRC.
Download 0 A.D.
Download 0 A.D. (Linux, Windows and Mac)
Ubuntu / Linux Mint users can install the latest 0 A.D. by using its official PPA. Add the PPA and install the game using the following commands:sudo add-apt-repository ppa:wfg/0ad
sudo apt-get update
sudo apt-get install 0ad
The application should work with all Nikon cameras that have built-in WiFi interfaces as well as external Nikon WiFi adapters WU-1a and WU-1b. Other external WiFi adapters, like WT-4A and WT-5A, may work, but were not tested.
Canon cameras are also supported and with the latest version, the application got support for Sony cameras as well.
Besides downloading the photos and images you've already taken, the application also comes with a real-time download mode, which allows transferring images to your computer as you shoot them, as long as your camera supports this.
For cameras that don't support real-time WiFi shooting, a staged-real-time feature can be used, which automatically transfers the photos as soon as you turn the WiFi off - a process which can be repeated (turn WiFi off, shoot some photos, then turn the WiFi off to get the photos transferred to your computer) without any user input on the computer.
- one-button click to download all new images and video from the camera, selected on either the camera or computer;
- fast downloads - Airnef uses optimized Media Transfer Protocol (MTP) parameters for sustained throughput around 2.5 MB/s (in my test under Ubuntu 15.10, the top transfer speed was 1.15 MB/s and I'm not sure why but I'll look into it);
- real-time download mode (and staged-real-time download mode - see above for explanations regarding this feature) - images are transferred to your computer as you shoot them;
- transfer images and videos using an extensive criteria selection such as: file type, start/end capture date, specific folders, card slot and so on;
- allows choosing the download order (oldest/newest first);
- renaming engine allows you to customize the names of directories and files for images you download;
- Airnef will continuously retry any failed communication/transfer, resuming the download exactly where it left off, even in the middle of a file;
- various minor features such as automatically synchronizing the camera's time to the system's time each time airnefcmd is executed, and more.
Using Airnef is pretty simple but just in case, here's how to quickly start using it. Firstly, you'll have to connect the camera to your computer's WiFi. To do this, enable the WiFi on your camera and on your computer, connect to your camera's WiFi.
Next, on your computer, launch Airnef and make sure that "Camera IP Address" is set to "192.168.1.1". At least for Nikon cameras, this should be the default IP address:
If you're in a network where this IP is already assigned (to your router for example), you can either disconnect from the network or change the camera IP - according to Airnef's website, for Nikon cameras this can be done via a one-time procedure using Nikon's Wireless Mobile Utility app (iOS and Android). You can find exact instructions for this on Airnef's homepage.
Next, click on "Select on Computer", choose which files to transfer, the download location and so on and click the "Start Download" button:
For real-time download, select "only realtime download" (or "normal download then realtime" to firstly download all the images/videos from your camera and then start the real-time feature) option from the dropdown, as you can see in the screenshot below:
After you click "Start download", a terminal window should pop up (if you've used the binary download; for the source, this is displayed in the terminal where you ran airnef), displaying the connection and transfer status:
To stop the transfer, press ctrl + c in this window.
For a lot more information and advanced usage, see Airnef's homepage.
Download Airnef (binaries available for Linux - 64bit only, Windows and Mac as well as source code)
To run it, simply extract the downloaded archive and double click the "airnef" executable.
For Linux 32bit (also works for 64bit obviously, if you prefer using the python source instead of the binary), firstly install python-tk. For Ubuntu, install it using the following command:sudo apt-get install python-tk
Then download the source code, extract the downloaded archive and in the folder where you've extracted it, run the following command to start the application:python airnef.pyw
Evernote is a popular note-taking service that supports saving text, full webpages, voice memos, video notes and more with a lot of useful features. There are official Evernote clients available for Windows, OS X, web (but it lacks many features) and mobile platforms but not for Linux.
Nixnote 2 beta 5, released recently, brings numerous bug fixes as well as various enhancements:
- added the ability to email notes;
- searching will now highlight PDF results;
- added Print Preview & the ability to only print selected text;
- notes that are marked as shortcuts are now visible in the tray icon;
- added the option to use notify-send instead of Qt's popup notification;
- a colors.txt file can now be added to customize note background color options;
- various GUI enhancements.
The latest Nixnote 2 beta also brings basic support for the nixnote2-cmd utility however, I should mention that this command line tool is not bundled with the NixNote 2 binaries.
For those not familiar with NixNote 2, here's a quick list of important Evernote features supported by this app:
- full synchronization of all notes and attachments;
- the ability to create, edit and delete notes, tags, notebooks and saved searches;
- the ability yo search notes and index attachments;
- allows using the image text recognition features provided by Evernote;
- supports multiple Evernote accounts.
Also, there are some Evernote features that aren't available or work differently in NixNote 2, including:
- slightly different search syntax (NixNote allows any term to be negated, where Evernote does not);
- no Twitter, Facebook and LinkedIn sharing;
- audio notes are not directly supported (you can't record audio notes through NixNote but you can use a note recorded with a different app as an attachment);
- Ink notes can't be implemented in NixNote because Evernote doesn't provide an API for it.
Note: To enable syncing with Evernote, from the NixNote 2 menu select Tools > Synchronize and authenticate NixNote 2 with Evernote.

On GIMP's 20th birthday (Nov 22), a new version of the free and open source image editor was released: 2.8.16. This is a bugfix release from the 2.8 stable series and it includes the following changes:
- seek much less when writing XCF;
- don't seek past the end of the file when writing XCF;
- Windows: call SetDLLDirectory() for less DLL hell;
- fix velocity parameter on .GIH brushes;
- fix brokenness while transforming certain sets of linked layers;
- always show image tabs in single window mode;
- fix switching of dock tabs by DND hovering;
- don't make the scroll area for tags too small;
- fixed a crash in the save dialog;
- fix issue where ruler updates made things very slow on Windows;
- fix several issues in the BMP plug-in;
- make Gfig work with the new brush size behavior again;
- fix font export in the PDF plug-in;
- support layer groups in OpenRaster files;
- fix loading of PSD files with layer groups.
The GIMP 2.8.16 release announcement also mentions that the devs' "immediate future plans are to release first public version in the unstable 2.9.x series that will feature fully functional GEGL port, 16/32bit per channel processing, basic OpenEXR support, vastly improved color management implementation, new tools, on-canvas preview for many filters, and more", this being the first milestone towards GIMP 2.10.
If you want to try the latest unstable GIMP, you can already do so by using a PPA.
Install GIMP 2.8.16 in Ubuntu or Linux Mint
To install the latest stable GIMP in Ubuntu (Precise and newer) / Linux Mint and derivatives, you can use Thorsten Stettin's PPA. Add the PPA and install GIMP using the following commands:sudo add-apt-repository ppa:otto-kesselgulasch/gimp
sudo apt-get update
sudo apt-get install gimpIt's important to mention that besides GIMP, this PPA also includes various GIMP plugins, such as G'MIC, and GIMP PLugin Registry.
For other Linux distributions, Windows and Mac OS X, see the GIMP downloads page.
How to revert the changes
In case you don't want to use GIMP 2.8.16 any more and you want to downgrade to the version available in the official Ubuntu repositories, you can purge the PPA using "ppa-purge":
sudo apt-get install ppa-purge
sudo ppa-purge ppa:otto-kesselgulasch/gimp
- clicking the "open containing folder" in the Firefox downloads menu, the file manager pops up behind the focused window;
- activating applications through indicators doesn't always bring them to the foreground, for instance Pidgin chat windows, the file manager opened via the "Open Dropbox folder" Dropbox AppIndicator menu item, Rhythmbox from the Ubuntu Sound Menu, etc.;
- if there's already a fileroller window open (Archive Manager, a compress/extract job, etc.), the second window you open is not focused.
Some focus-related issues were marked as fixed a while back, but some continue to occur and there are comments, as well as bug reports, which suggest a simple solution which should fix this issue: setting "Focus Prevention level" to "Off" in CompizConfig Settings Manager (obviously you need to be using Compiz for this to work).
In case you're not aware, Ubuntu (with Unity) ships with "Focus Prevention level" set to "Low" by default. For instance, to work around this issue, Ubuntu MATE, which allows you to easily switch to Compiz via MATE Tweak, ships with this option set to "Off".
To apply the fix/workaround I mentioned above, firstly install CompizConfig Settings Manager:sudo apt-get install compizconfig-settings-manager
Then open CompizConfig Settings Manager and under General Options > Focus & Raise Behaviour tab, set "Focus Prevention Level" to "Off":
That's it! If later on you decide you want to switch back to the default behaviour, simply set the "Focus Prevention Level" back to "Low".
As a bonus, this also fixes the issue with Nemo (with Unity patches) opening in the background when there's a focused window (which I think is a bug in Nemo).
Using "When", you can set your desktop to perform various tasks depending on certain conditions. For instance, you can synchronize files, perform some cleanup actions, auto import photos from external storage devices and many other tasks (these are examples and require adding commands or scripts to "When"), all based on conditions such as a command exit code or output, a given time interval, file/folder changes and more.
Even though for some tasks you'll have to write your own scripts, When makes it easier to use them as you won't have to include all the conditions supported by When in your scripts.
According to its developer, the application "is not generally intended as a replacement to cron and the Gnome Task Scheduler, although to some extent these utilities might overlap".
He adds that "When is intended to be more flexible, although less precise, and to provide an alternative to more complicated solutions -- such as the implementation of cron jobs that check for a particular condition and execute commands when the condition is verified".
Using "When", you can create tasks that depend on the following conditions:
- command: exit code, standard output, standard error, with options for exact match, case sensitive and regular expression;
- time interval (every X minutes/hours);
- at a given date/time;
- idle session;
- event: startup, shutdown, suspend, resume, connect/disconnect storage device, join/leave network, screensaver started / return from screensaver, session lock/unlock and a command line trigger (some conditions, like the session lock/unlock and the screensaver events might not work under Linux distributions other than Ubuntu due to the way they are currently detected);
- file / directory change;
- user defined event (dbus - advanced feature).
For each task, you can specify a command, a working folder, add environment variables and check for the command success or failure (or check for nothing and just run the command ignoring the output).
From the application settings you can change the tray/indicator icon theme, set the maximum concurrent tasks, log level, enable or disable file and directory notifications and more:
Other When features include an option to pause all tasks (can be accessed from the tray/indicator menu) as well as a task history window which includes the exit code for each tasks that ran so far, along with its result:
To use the application, firstly create a new task (from the tray/indicator menu select "Edit Tasks"), enter a name, command and so on and click "OK":
Then you need to assign a condition for the newly created task - to do this, from the tray/indicator menu, select "Edit Conditions", enter a name for your new condition, type, etc. and under "Tasks", select the task you've created from the drop-down:
Important: don't use spaces for the task / condition name as it won't work (the Ok button is grayed out if the name contains spaces).
For more information on When and how to use it, see its GitHub page, the When tutorial and the examples available HERE.
Install When in Ubuntu or Linux Mint
To install "When" in Ubuntu, Linux Mint and derivatives, follow the steps below:
1. Download the latest When (deb) from GitHub and install it.
2. To complete the When installation, run the following command:
/opt/when-command/when-command --install(without running the command above, you won't have a When menu / Dash entry, the option to allow it to start on login won't work, etc.)
3. (Optional) Install "python3-pyinotify" for file/folder notification support.
sudo apt-get install python3-pyinotify
Note that on some desktop environments (this happened in my test while using Linux Mint Cinnamon), the When menu entry might not show up until you restart your session (logout/login).

This bug only occurs for applications that use header bars (client-side decorations) and it affects Ubuntu (with Unity), while Xubuntu, Ubuntu MATE and Ubuntu GNOME don't seem to be affected (at least in my quick test). Update: MATE with Compiz enabled is also affected so I guess any desktop environment under which you use Compiz is affected (thanks to pawelp!).
Here's a screenshot with GNOME Clocks (an app that uses header bars) under Unity (Ubuntu 15.10), using Numix GTK theme:
I'm not sure when/if this bug will be fixed but until then, you can fix it yourself. Below you'll find a simple fix which will remove the black borders no matter what GTK theme you're using.
To fix the large black borders bug in Ubuntu, open ~/.config/gtk-3.0/gtk.css (create the ~/.config/gtk-3.0 folder if it doesn't exist) with a text editor (I'll use Gedit below):mkdir -p ~/.config/gtk-3.0
gedit ~/.config/gtk-3.0/gtk.cssand in this file, add the following:
}This forces any theme you use to have a 1 pixel border. You can use any value you want - for instance, use "0" for borderless windows.
Then save the file and close all the applications affected by the black border bug (or you can log out and log back in), then try them again and you shouldn't see large black borders any more.
Here's the same application I've used above to show the bug (GNOME Clocks, running under Unity), after applying the fix:
Thanks to Phaeilo @ GitHub for the fix!
The original Screenkey was abandoned but thanks to Yuri D'Elia, the application lives on, through a fork that's an almost complete rewrite of screenkey 0.2 (the last version released by the original developer), which includes quite a few improvements and new features, such as:
- multi-monitor support;
- configurable font/size/position;
- several keyboard translation methods;
- key composition/input method support;
- improved backspace processing;
- Normal/Emacs/Mac caps modes;
- dynamic recording control by pressing both control keys;
- switch for visible shift and modifier sequences only;
- bug fixes.
The latest Screenkey 0.8 also comes with various advanced features, such as placing the Screenkey window on top of an application (first screenshot below), command-line placement (these features require "slop", which is not available in the official Ubuntu repositories but is available in the main WebUpd8 PPA and is installed automatically when you install Screenkey from our PPA) and more.
Here's Screenkey in action:
Since I couldn’t find the latest Screenkey 0.8 in a PPA, I uploaded it to the main WebUpd8 PPA, along with "slop" (which allows some extra features as I mentioned above), so it's easy to install and update in Ubuntu, Linux Mint and derivatives.
In Ubuntu (w/ Unity), Screenkey doesn't work out of the box because of a bug however, I've modified the package desktop file to run Screenkey with "--no-detach" as a workaround so you shouldn't encounter this issue (unless you run Screenkey from a terminal, in which case add "--no-detach" to get it to work until this is fixed).
Install Screenkey 0.8 in Ubuntu or Linux Mint
The latest Screenkey 0.8 is available in the main WebUpd8 PPA. To install it in Ubuntu, Linux Mint and derivatives, use the following commands:sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install screenkey
Arch Linux users can install Screenkey via AUR.
For other Linux distributions, download Screenkey via GitHub.

This works well for KDE and GNOME (as well as Unity) but you may encounter issues under other desktop environments such as Xfce, Cinnamon, MATE and others (I'm not sure what Qt5 versions are affected by this, but it seems to be fixed in the latest Qt 5.5.1 according to THIS comment).
Here's an example (Audacious 3.7 using the Qt5 interface under Linux Mint 17.2 with Cinnamon):
Instead of "Open Files", "Add Files" and so on, Audacious should have icons. The app is also not using the GTK+ Qt5 style.
To force the Qt5 style or icon theme, you can use an application called Qt5ct (Qt5 Configuration Tool). Besides the style and icons, Qt5ct can also be used to change various other Qt5 settings, such as fonts, add custom style sheets and tweak other interface settings such as the double click interval, enable icons in menus and dialog buttons and more:
Here's another Audacious 3.7 Qt5 interface screenshot taken under Linux Mint 17.2 Cinnamon, after using Qt5 Configuration Tool to set the icon theme to Mint-X and the style to GTK+:
To make it easier to install Qt5ct for Ubuntu and Linux Mint (and derivatives) users, I've uploaded the latest version in the main WebUpd8 PPA. I didn't package the application and instead, I've used the packaging from THIS PPA. I decided rebuild the packages because that PPA comes with an older version and the packages are only tested for Ubuntu 14.04 (and in my test, the Ubuntu 15.04 and 15.10 packages weren't installable). So the packaging credits go to "hda_launchpad".
Install and configure Qt5 Configuration Tool in Ubuntu or Linux Mint
1. To add the main WebUpd8 PPA and install the latest Qt5 Configuration Tool (Qt5ct) in Ubuntu 14.04, 15.04 and 15.10 / Linux Mint 17.x and derivatives, use the following commands:sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install qt5ctIf you don't want to add the PPA, you can download the DEB from HERE (but you won't receive any updates unless you add the PPA).
Arch Linux users can install Qt5ct from the Community repository. For other Linux distributions, you can download Qt5ct from SourceForge.
2. Once installed, there's one more step you need to follow or else the settings you apply using Qt5ct won't be applied - you need to open ~/.profile with a text editor (".profile" is a hidden file in your home directory so use CTRL + H to show hidden files) and at the bottom of this file, add the following line:export QT_QPA_PLATFORMTHEME="qt5ct"Then, save the file, log out and after you login you can use Qt5 Configuration Tool to change the Qt5 style, icon theme and so on.
You'll need to restart any Qt5 applications that were running to see the changes.
If later on you want to revert the changes, simply remove the "export QT_QPA_PLATFORMTHEME=qt5ct" line from your ~/.profile file and restart your session (logout).
- I've tried adding this in Lubuntu 15.10 (uses LXDE) to ~/.profile, ~/.xsessionrc as well as /etc/environment and it didn't work for some reason (but exporting it using a terminal and then running a Qt5 app works, so the Qt5ct application works properly). If you find a way to get this to work in Lubuntu, let us know in the comments!
- Using Qt5ct breaks the `Albert` user interface (probably because Albert tries to use the theme specified by Qt5ct).
via Arch Wiki
Albert allows you to quickly run applications, open files or bookmarks (Chromium only), search the web, calculate and more. The application is inspired by Alfred (Mac), is written in C++ and based on the Qt framework, and it's desktop environment agnostic so you can use it with any desktop environment.
- launch applications;
- open files;
- open Chromium bookmarks;
- calculate math expressions;
- search the web in your default web browser (it ships with various built-in search engines such as Google, YouTube, Amazon, Ebay, GitHub and Wolfram Alpha and you can easily add more);
- configurable hotkey and maximum number of items to display;
- ships with 5 themes by default.
Since our initial article about Albert, the application has received quite a few changes:
- implemented a plugin system and ported all the old modules to the new plugin system;
- new feature/plugin: System, which allows performing actions like poweroff, reboot, lock screen, etc. (you may need to set the commands for this to match your desktop environment);
- you can now ignore folders by adding them to an ".albertignore" file in your home directory;
- added actions (TAB switches to alternate action, if any);
- added support for Unity qucklists as actions (use the TAB key to access the quicklists);
- Files plugin: you can now filter indexed files by type, symlink support.
Besides these changes, there have also been numerous bug fixes. For instance, the hotkey used to launched Albert should now be correctly saved, even if you kill Albert (e.g. using "killall albert").
According to the Albert wiki, Albert works with Qt 5.1 and newer however, there are some known bugs that occur with Qt (5) versions older than 5.3 (which affects Ubuntu 14.04 / Linux Mint 17.x for instance) and since those bugs are in Qt, they can't be fixed in Albert.
I am not exactly sure exactly what bugs the wiki is referring to but from what I can tell, if you use a Qt version older than 5.3, you can't use the Super (Meta) key as a hotkey for Albert - other than that, I couldn't find any other issues but there might be others!
To install the latest Albert in Ubuntu, Linux Mint and derivatives by using the main WebUpd8 PPA, use the following commands:sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install albert
For how to install Albert in Arch Linux, Fedora or from source, see its wiki.
If you encounter bugs, report them @ GitHub.
Tip: if you're looking for similar applications but you're not satisfied with Albert, you can try Kupfer (available in the official Ubuntu repositories; not updated in a long time but it still works great and it comes with an impressive number of plugins) and Synapse (available in the repositories for Ubuntu 15.10 and 16.04; for 14.04, you can use THIS PPA).
Now back to Audacious. The latest Audacious, which, in case you're not familiar with, is a fast, lightweight audio players, ships with various Qt interface improvements, including plugins which have been ported to Qt, such as the Winamp Classic Interface, the Playlist Manager, Search Tool and Status icon, and more.
Winamp Classic interface
Here's a list of the most important changes in Audacious 3.7:
- GTK interface only:
- Internet streams can be recorded while playing via a simple record button;
- the playlist export window displays supported formats in a drop-down list;
- a new, unified window has been added for managing equalizer presets;
- the user interface automatically adjusts to be more usable on high-resolution screens;
- playlists can be shuffled by whole albums rather than single tracks.
- Qt interface only:
- the Qt interface can be customized with several new appearance settings;
- the following plugins have been ported to Qt: Winamp Classic Interface, Playlist Manager, Search Tool and Status Icon;
- various small fixes and improvements, such as a visualizer in the info bar, to bring the interface closer to feature-parity with the GTK+ interface;
- an "Edit Lyrics" option has been added to the LyricWiki plugin, which opens the edit page for the current song;
- guessing of missing tag fields can be disabled;
- decoding and playback of standard input is possible with e.g. "cat file.mp3 | audacious -";
- in dual GTK and Qt builds, incompatible plugins are hidden to avoid confusion;
- most audtool commands now apply to the playlist which is playing, even if it is in the background;
- bug fixes.
A complete changelog can be found HERE.
Install Audacious 3.7 in Ubuntu or Linux Mint
As usual, the latest Audacious is available in the main WebUpd8 PPA. The PPA provide Audacious build with GTK2 and Qt interfaces (I can't also enable the GTK3 interface because it requires separate builds).
To install Audacious 3.7 in Ubuntu 14.04, 15.04 or 15.10 / Linux Mint 17.x and derivatives, use the following commands:sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install audacious
Once installed, select Audacious from the Dash / menu to launch the GTK2 interface or "Audacious Qt Interface" for the Qt interface.
