The Sipeed NanoKVM is a pretty neat device. Level 1 Techs review: The procedure to update firmware however, is a little obscure. The system has two components: The Firmware - the embedded linux image that boots the device; and The NanoKVM application - which runs the Web UI and does video encoding etc etc. The application itself can be updated within the Web UI, but the firmware itsel...

Starting with BIND 9.19, you can now set up DNS over TLS in the forwarders option. You can use this in Fedora now by installing the bind9-next packages instead of bind. Configuring this is quite simple, the example below uses Google, Quad9 and Cloudflare as upstream DNS servers: tls cloudflare-tls { remote-hostname "one.one.one.one"; }; tls quad9-tls { remote-hostname "dns.quad9.net"; }; tls...

The Linus Tech Tips channel ShortCircuit recently did a video on an NTP time source card. Video here for reference: It’s really nice to have your own clock source, but when you start digging into the price of those units, saying you might not get change from $13,000 isn’t a lie. Of course, that’s for the highest end cards - but do we really need that for a small user? What if you could get m...

If you’re like me, you’ve got a home lab with a dozen or so virtual machines doing all sorts of things - and each of them are pulling down updates from somewhere on the internet. What if you could have a single endpoint for all VMs to reference? That way, updates that are common would be distributed to all systems at LAN speeds after the first download. Introducing - mod_cache for Apache :)...

For years, I’ve run a set of Logitech Z-5500 speakers into an optical port on my PC. It gives good quality 5.1 audio, and supports AC3 + DTS digital passthrough as well as 44, 48, and 96khz bitrates. The problem is, the speakers go into a ‘sleep’ mode where it takes nearly a second to bring the amp back online to play audio - so notification sounds are often not played at all. To correct this...
