Ubuntu Kylin is an official Ubuntu flavour whose primary goal is to create a variant of Ubuntu optimised for Chinese users (using the Simplified Chinese writing system), although it also supports other languages. The default desktop is called UKUI (Universal Kylin User Interface) which is based on MATE desktop and is developed with the Qt toolkit. UKUI strives to adhere to the friendly-and-simple design concept. The distribution also includes more than 20 applications developed in-house, including Kylin Assistant, Kylin Video, Kylin Screenshots and Software Center.

Ubuntu MATE is a stable, easy-to-use operating system with a configurable desktop environment. It is ideal for those who want the most out of their computers and prefer a traditional desktop metaphor. With modest hardware requirements it is suitable for modern workstations, single board computers and older hardware alike. Ubuntu MATE makes modern computers fast and old computers usable.

Ubuntu MATE has a number of guiding objectives and goals.

• Accessible to all, regardless of language and physical ability.

I

• ncrease both Ubuntu and MATE Desktop user adoption.
• Ubuntu alternative for computers that aren't powerful enough to run a composited desktop.
• First choice Ubuntu platform for remote workstation solutions such as LTSP and X2Go.
• Recreate the halcyon days of Ubuntu for users who prefer a traditional desktop metaphor.
• Use themes and artwork similar to Ubuntu so that Ubuntu MATE is immediately familiar.
• When possible contribute to Debian so both the Debian and Ubuntu communities benefit.
• Software selection will favour functionality and stability over lightness and whimsy.

Like a tent, you can carry Tails with you and use it anywhere.

Your secure computer anywhere
To use Tails, shut down the computer and start on your Tails USB stick instead of starting on Windows, macOS, or Linux.

You can temporarily turn your own computer into a secure machine. You can also stay safe while using the computer of somebody else.

Tails is a less than 2GB download and takes ½ hour to install. Tails can be installed on any USB stick of 8 GB minimum. Tails works on most computers less than 10 years old. You can start again on the other operating system after you shut down Tails.

You don't have to worry about the computer having viruses because Tails runs independently from the other operating system and never uses the hard disk. But, Tails cannot always protect you if you install it from a computer with viruses or if you use it on a computer with malicious hardware, like keyloggers.

Amnesia
Tails always starts from the same clean state and everything you do disappears automatically when you shut down Tails.

Without Tails, almost everything you do can leave traces on the computer:

• Websites that you visited, even in private mode
• Files that you opened, even if you deleted them
• Passwords, even if you use a password manager
• All the devices and Wi-Fi networks that you used

On the contrary, Tails never writes anything to the hard disk and only runs from the memory of the computer. The memory is entirely deleted when you shutdown Tails, erasing all possible traces.

Persistent Storage
You can save some of your files and configuration in an encrypted Persistent Storage on the USB stick: your documents, your browser bookmarks, your emails, and even some additional software.

The Persistent Storage is optional and you always decide what is persistent. Everything else is amnesic.

Digital security toolbox
Tails includes a selection of applications to work on sensitive documents and communicate securely.

All the applications are ready-to-use and are configured with safe defaults to prevent mistakes.

Tails includes:

• Tor Browser with uBlock, a secure browser and an ad-blocker
• Thunderbird, for encrypted emails
• KeePassXC, to create and store strong passwords
• LibreOffice, an office suite
• OnionShare, to share files over Tor
• Metadata Cleaner, to remove metadata from files
• and many more!

To prevent mistakes:

• Applications are blocked automatically if they try to connect to the Internet without Tor.
• Everything in the Persistent Storage is encrypted automatically.

Tails does not write anything to the hard disk. All the memory is deleted when shutting down.

Warnings: Tails is safe but not magic!
Tails is safer than any regular operating system. But Tails, or any software or operating system, cannot protect you from everything—even if they pretend to.

The recommendations below will keep you even safer, especially if you are at high risk.

Tails is designed to hide your identity.

But some of your activities could reveal your identity:

• Sharing files with metadata, such as date, time, location, and device information
• Using Tails for more than one purpose at a time

Tails uses the Tor network because it is the strongest and most popular network to protect from surveillance and censorship.

But Tor has limitations if you are concerned about:

• Hiding that you are using Tor and Tails
• Protecting your online communications from determined, skilled attackers


• Tails can safely run on a computer that has a virus.

But Tails cannot always protect you when:

• Installing from an infected computer
• Running Tails on a computer with a compromised BIOS, firmware, or hardware

GrapheneOS

The private and secure mobile operating system with Android app compatibility. Developed as a non-profit open source project.

GrapheneOS is a privacy and security focused mobile OS with Android app compatibility developed as a non-profit open source project. It's focused on the research and development of privacy and security technology including substantial improvements to sandboxing, exploit mitigations and the permission model. It was founded in 2014 and was formerly known as CopperheadOS.

GrapheneOS improves the privacy and security of the OS from the bottom up. It deploys technologies to mitigate whole classes of vulnerabilities and make exploiting the most common sources of vulnerabilities substantially more difficult. It improves the security of both the OS and the apps running on it. The app sandbox and other security boundaries are fortified. GrapheneOS tries to avoid impacting the user experience with the privacy and security features. Ideally, the features can be designed so that they're always enabled with no impact on the user experience and no additional complexity like configuration options. It's not always feasible, and GrapheneOS does add various toggles for features like the Network permission, Sensors permission, restrictions when the device is locked (USB peripherals, camera, quick tiles), etc. along with more complex user-facing privacy and security features with their own UX.

Many of our past features were contributed to AOSP, Linux and other projects to improve privacy and security for billions of users.

GrapheneOS also develops various apps and services with a focus on privacy and security. Vanadium is a hardened variant of the Chromium browser and WebView specifically built for GrapheneOS. GrapheneOS also includes our minimal security-focused PDF Viewer, our hardware-based Auditor app / attestation service providing local and remote verification of devices, our modern privacy / security focused camera app, and the externally developed Seedvault encrypted backup which was initially developed for inclusion in GrapheneOS.

No Google apps or services

GrapheneOS will never include either Google Play services or another implementation of Google services like microG. It's possible to install Play services as a set of fully sandboxed apps without special privileges via our sandboxed Google Play compatibility layer. See the FAQ section for more details on our plans for filling in the gaps from not shipping Play services and Google apps.

Two-factor fingerprint unlock

GrapheneOS adds the option to require entering a 2nd factor PIN after successfully authenticating with a fingerprint on the lockscreen in order to complete unlocking the device. Since Android/iOS use biometric unlock as a secondary unlock mechanism for convenience, this allows users to make use of a strong passphrase as their primary unlock method with the convenience of a fingerprint and short PIN for secondary unlock. Failure to enter the correct PIN counts towards the standard attempt limit.

Supports longer passwords

GrapheneOS supports setting longer passwords by default: 128 characters instead of 16 characters. This avoids the need to use a device manager to enable this functionality.

This feature allows users to make use of diceware passwords if they don't want to depend on the security of the secure element which provides very aggressive throttling and offers a high level of security even for a random 6 digit PIN.

Auto reboot

GrapheneOS provides an auto-reboot feature which reboots locked devices after a set period of time to put data at rest. A countdown timer is started each time the device is locked, and the device will reboot if a successful unlock doesn't occur before the timer reaches zero. Unlocking any profile cancels the timer, not just the Owner profile.

The timer is set to 18 hours by default, but can be set to values between 10 minutes and 72 hours, or turned off.

This feature doesn't apply when the device is in "Before First Unlock" state, meaning that it will not lead to the device continuously rebooting, as data is already at rest.

The feature is implemented in the init process, preventing it from being bypassed through system process crashes since an init crash causes a kernel panic which leads to a reboot.
