Radxa Rock - the cheap and powerful quad-core mini-computer has already receiving great success with majority of stock vanishing across all major online distributors. Luckily, I had received my Radxa Rock a while back and has now successfully taken over the job of my Wireless Network Attached Storage (NAS) from Raspberry Pi.

The process of setting up NAS on Radxa Rock is much more easier then Raspberry Pi as the external disk is automatically detected and mounted on every boot (Thanks to Ubuntu Desktop based Linaro image), but when using the folder sharing via Samba Share we need to add an extra line to smb.conf to make the data accessible over network.

If you try to run VLC under root user on Linux, you will be blocked with message : "VLC is not supposed to be run as root. Sorry. If you need to use real-time priorities and/or privileged TCP ports you can use vlc-wrapper (make sure it is Set-UID root and cannot be run by non-trusted users first).". While it is a good security practice to not run non-system executables under root privileges, but at times you might need the exception. Here's a solution to allow VLC and cvlc (command-line version of vlc) run under the root user-account.

Similar to Opera Turbo technology, Google Chrome features an "data compression proxy" for Android and Apple iOS mobile-devices which when enabled opens a connection between the user phone and optimization servers running in Google's datacenters relaying all non-encrypted HTTP requests over this connection. The SSL secured proxy connection performs intelligent compression and minification of HTML, JavaScript and CSS resources which are not essential to render the page. These optimizations, combined with gzip compression for all resources, DNS lookups from proxy and images converted to WebP with resulting sizes upto 80% smaller provides huge bandwidth savings and resulting in faster web-browsing experience.

This feature is not available for Google Chrome Desktop users, however a free Chrome extension now allows users to get the same savings on their desktop computers. The extension sends all HTTP (but not HTTPS) traffic through Chrome Data Compression Proxy server, which utilizes SPDY protocol to speed up web browsing. Users can check bandwidth savings by visiting chrome://net-internals/#bandwidth and can disable compression-proxy by clicking the green bolt icon from the toolbar.
