In the second part of MINIX NEO N42C-4 review (and on linuxium website), we looked at the device and the performance using Windows. In this third part, we will look at how to install and the performance of using Linux (Ubuntu). The BIOS does not include an option to select Linux as a boot OS and a standard Ubuntu ISO written to a USB will not boot. So to install Ubuntu to the eMMC as dual-boot first it was necessary to respin a standard Ubuntu ISO using my ‘isorespin.sh’ script with the ‘–apollo’ option, and which after creating a LiveUSB using the ‘dd’ command was used to boot and install Ubuntu. First let’s remind ourselves of the hardware configuration by running some standard Linux commands:

Transport Layer Security (TLS) is the protocol that allows for secure websites (via https), and currently, TLS 1.2 is the version most commonly used today, with 1.0 and 1.1 still supported by many servers for backward compatibility with older browsers, including the one running this blog. TLS 1.3 is the next version, already supported in libraries and server software such as wolfSSL or nginx, and promises to be more efficient – important for battery operated devices (IoT) – thanks to features like zero-RTT (0-RTT) mode, speedy with a restructured handshake state machine, and more secure. However, changes in security protocol may mess up connection with some browsers or middleboxes, as I experience when I enabled https on CNX Software using Let’s Encrypt with nginx and Cloudflare, with around 0.5% of users losing access due to using older web browsers and operating systems such as Internet Explorer on Windows XP. According […]
