Critical Mass (also known as Critter) is a top-down shoot-em-up game where your home world has been infested by an aggressive army of space critters and you are required to pilot a small spacecraft to destroy them all.

You pilot your ship through the dreaded "Maelstrom" asteroid belt -- suddenly your best friend thrusts towards you and fires, directly at your cockpit. You raise your shields just in time, and the battle is joined.

The deadliest stretch of space known to mankind has just gotten deadlier. Everywhere massive asteroids jostle for a chance to crush your ship, and deadly shinobi fighter patrols pursue you across the asteroid belt. But the deadliest of them all is your sister ship, assigned to you on patrol. The pilot, trained by your own Navy, battle hardened by months in the Maelstrom, is equipped with a twin of your own ship and intimate knowledge of your tactics.

The lovely Stratocaster R&R facility never sounded so good, but as you fire full thrusters to dodge the latest barrage you begin to think you'll never get home...

You are captain of the cargo ship Chromium B.S.U., responsible for delivering supplies to our troops on the front line. Your ship has a small fleet of robotic fighters which you control from the relative safety of the Chromium vessel. This is an OpenGL-based shoot 'em up game with fine graphics.

Your mission:

• Do not let ANY enemy ships get past your fighters! Each enemy ship that makes it past the bottom of the screen will attack the Chromium, and you lose a fighter.
• Use your fighters as weapons! Crash into enemies to destroy them before they can get past you.
• Strategic suicide is a powerful tactic! When the Chromium launches a new fighter, it releases a high energy burst which destroys all enemies in range.
• Self-destruct to preserve your ammunition! A double-right-click will cause your current fighter to self-destruct. Before the ship blows up, it ejects its ammunition so that the next fighter can pick it up.

• Ideal for LoDPI,
• Potentially Problematic,
• Ideal for HiDPI,
• Fairly High for HiDPI, or

Browse the Internet in private without leaving a trace of history on your computer. Ephemeral is a stripped down private browser that's perfect for avoiding persistent cookies or web trackers. Close the window and all traces of your browsing are removed from your device.

Handy features:

• Easily open pages in any other installed browser
• Search right from the URL bar
• Pick between privacy-respecting search engines from the menu
• Quickly disable or re-enable JavaScript from the menu

Useful keyboard shortcuts and gestures:

• Navigate back or forward with a two-finger swipe on your trackpad
• Add a website to the URL suggestions with the ⭐️ icon or Ctrl+D
• Find text on the page with Ctrl+F
• Zoom in or out with Ctrl+Plus and Ctrl+Minus
• Open a new window with Ctrl+N
• Hit Ctrl+W to close the current window or Ctrl+Q to quit all windows

Ephemeral protects you in five key ways:

1️⃣ Always incognito. From the second you open an Ephemeral window until you close it (or hit the Erase button), Ephemeral is in private browsing mode. That means history, cookies, local storage, passwords, etc. are all blown away as soon as you leave.

2️⃣ Sandboxed. Each window uses a separate instance of the browser engine, domains inside each window are rendered using different processes, and the engine’s processes are sandboxed from one another to keep you safe. Sign into a service in one window, and sites in other windows will have no idea.

3️⃣ No third-party cookies. Ephemeral blocks cookies from third-party sources, which cuts down on advertising cookies and other unwanted forms of cross-site tracking.

4️⃣ No telemetry. Ephemeral does not touch the network until you explicitly load a web page or perform a search. Even then, no usage data is ever collected—I have no idea what you do with Ephemeral, and I don't want to know!

5️⃣️ Ephemeral uses DuckDuckGo—the search engine that doesn’t track you—by default to avoid as much Google tracking as possible. You can also choose StartPage.com from the menu if that’s your preference, or even set your own entirely custom search engine.

Make privacy a habit by opening links in Ephemeral by default, knowing you can always jump back into a traditional browser like Epiphany, Firefox, Chrome, Opera, Brave—or any other installed browser—with one click. Perfect in case you want to use saved passwords or other extensions.

Remember, Ephemeral and any browser's incognito or private mode can only do so much: they mitigate some tracking and don't store data on your device, but they won't stop your ISP, government, or determined websites from tracking you.

For the best protection, always use a VPN.

0 A.D. is a real-time strategy (RTS) game of ancient warfare. It's a historically-based war/economy game that allows players to relive or rewrite the history of thirteen ancient civilizations, each depicted at their peak of economic growth and military prowess.

The thirteen factions are: Three of the Hellenic States (Athens, Sparta and Macedonia), two of the kingdoms of Alexander the Great's successors (Seleucids and Ptolemaic Egyptians), two Celtic tribes (Britons and Gauls), the Romans, the Persians, the Iberians, the Carthaginians, the Mauryas and the Kushites.

RawTherapee is a powerful, cross-platform raw photo processing program. It is written mostly in C++ using a GTK+ front-end. It uses a patched version of dcraw for reading raw files, with an in-house solution which adds the highest quality support for certain camera models unsupported by dcraw and enhances the accuracy of certain raw files already supported by dcraw. It is notable for the advanced control it gives the user over the demosaicing and development process.

RawTherapee is designed for developing raw files from a broad range of digital cameras, as well as HDR DNG files and non-raw image formats (JPEG, TIFF and PNG). The target audience ranges from enthusiast newcomers who wish to broaden their understanding of how digital imaging works to semi-professional photographers. Knowledge in color science is not compulsory, but it is recommended that you are eager to learn and ready to read our documentation (RawPedia) as well as look up basic concepts which lie outside the scope of RawPedia, such as color balance, elsewhere.

Of course, professionals may use RawTherapee too while enjoying complete freedom, but will probably lack some peripheral features such as Digital Asset Management, printing, uploading, etc. RawTherapee is not aimed at being an inclusive all-in-one program, and the open-source community is sufficiently developed by now to offer all those peripheral features in other specialized software.

For example, you can record your musical idea with a MIDI keyboard, write out transposing parts for the members of a brass band, and record the band playing these parts all in the same document in the same application. Rosegarden supports a variety of import and export formats, and works well in conjunction with other applications.
