Shirts, CDs, & Case Badges for GNU/Linux

Debian stands out as a robust GNU/Linux distribution for individuals and organizations prioritizing stability, security, and reliability, all underpinned by community involvement and long-term support. Established in 1993, Debian is among the oldest and most influential distributions in the Linux ecosystem. A significant number of other distributions, such as Linux Mint and Ubuntu, have roots in Debian, showcasing its foundational role in the development of various GNU/Linux-based systems.

One of the distinguishing features of Debian is its traditional non-rolling release model, which makes it particularly suitable for server environments. Once a stable release is made available, users receive updates solely for security purposes. This is great in terms of stability, but it is wise to be aware that it can complicate the installation process on newly released hardware. However, this approach ensures that the system remains stable and reliable in production settings, minimizing the risk of disruptions.

Security and adherence to free software principles are paramount in Debian's development process. The pathway to becoming a Debian developer or package maintainer is rigorous, often involving a multi-year vetting process where prospective contributors gradually build trust through small contributions. This meticulous approach helps uphold high standards within the community, and the majority of packages in the main repository are composed of free software, allowing for a greater assurance of security. While the inclusion of non-free firmware in installation media marks a shift from previous policies, it remains a critical aspect of evaluating the overall security of the distribution.

* Please note that while GNU/Linux has support for a lot of hardware not all hardware is created equal and the user experience may suffer on systems that aren't fully supported or designed for GNU/Linux. If you need advice on the best hardware to get feel free to contact our support team.

Have you been looking forward to a new release of libreCMC, but found it too tiring or technically cumbersome to perform an upgrade yourself? We now offer libreCMC upgrade services. We can ship a new microSD card configured to your liking for our Gigabit TPE-R1400 router and for our other wireless router models you can mail us what you have for flashing and configuring. We'll wipe everything from it, upgrade it to the latest release of libreCMC, and then configure the router to your preferred setup as specified by selecting from the available options below. We have many configurations to choose from.

• Reduce the risk of messing up a complex router configuration


• We offer a select set of popular configurations so even rather complex setups can be accommodated


• Support for our USB 4G modems: Share your 4G cellular connection with other users


• Support for our USB 4G modems w/ outgoing traffic transparently passed through our VPN servers


• Support for mesh configurations: Get wifi to those pesky corners of the house where wireless doesn't ordinarily reach


• Support for our PenguinVPN service: All traffic is transparently passed through our privacy friendly VPN service

Note: Postage for shipping routers to ThinkPenguin, Inc is not included. Return shipping however is included. Upon purchase we will send an email containing an RMA # and shipping information. At checkout please include your prior order # if you've already purchased our PenguinVPN service and are having us setup the PenguinVPN service again using your previously purchased subscription.

Support is available for 6 months from the date of purchase of upgrade services/microSD cards.

Warning: Please be aware we are not offering custom configurations or porting custom configurations. We are only offering new releases of libreCMC with a stock configuration or a configuration that was an option with our routers when originally purchased (or has since become available as an option). This means it's almost like your getting a new router, at least in terms of software, and the configuration. All other data a router had and any user-customized settings will be erased.
