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.

This program is a structured notetaking application based on GTK+ 3. Write your notes in instantly-formatted Markdown, organise them in a tree of folders that can be instantly navigated from within the program, and add hand-drawn notes by mouse, touchscreen or digitiser.

1. Why?

I figured it would be nice to have a free-software, platform-independent OneNote. While there is a remarkable number of free (speech or beer) notetaking applications out there, to my best knowledge, none of them simultaneously check the following boxes:

• note organisation
• text as a first-class object
• formatting
• simple, standard on-disk format
• tablet input

2. Usage notes

Note management

• To create a new note, doubleclick a "+" node in the tree view and enter a name.
• To create a new folder, doubleclick a "+" node in the tree view and enter a name ending in "/", e.g. new "folder/".
• Notes will be sorted alphabetically.
• You can move notes and whole folders between folders by dragging and dropping.
• Files are saved automatically when the window is closed, when a different file is opened, and after a timeout when no user action is performed.

Markdown

• Some markdown features are unsupported as a stylistic choice or because of parser limitations. If you are feeling adventurous, you can adjust the markdown parser by editing the GtkSourceView language definition in "sourceview/markdown.lang".
• Add LaTeX math using single "$" signs, e.g. "$\int x dx$".
• Some markdown will be hidden ("rendered") unless your cursor is next to it.

Note management

• Drawings can currently only be deleted whole. (This will be fixed eventually.)
• To edit the default colour palette, right-click any of the colour buttons on the right-hand toolbar.
• Due to present limitations, drawing clears the undo stack.
• When copypasting text into other applications, drawings will be automatically converted into data URL PNGs.

Note management

• The program loads a custom Gtk+ stylesheet found in "data/stylesheet.css". Clear it if parts of the UI look wonky.
• If something unexpected happens, it is often useful to run the program from a terminal and look at stdout.

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
• Choose to automatically open certain sites in another browser from the "Open page in…" menu

Useful keyboard shortcuts and gestures:

• Navigate back or forward with a two-finger swipe on your trackpad
• Open page in another browser with Ctrl+O
• 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.
