In older versions of Xemn, each DomU could effectively use the system time of the Dom0. That was remove after Xen 4 or so. In versions after that issues of clock drift need to be addressed. I was investigating this and came across a discussion of best practices about setting the Limux clocksource on DomU’s. …
Let’s suppose one is tasked with a complex set of calculations where the input data loads from a database and the output data saves to a database. This has come up a number of times in my consulting work. There are 2 approaches: Use language of choice, read data, perform calculations, write data Work entirely …

I don’t like JSON, or YAML. Moving on. Actually I’ve been exploring binary interchange formats. I am not the first to note that converting data from binary, to text, and back, is often suboptimal, especially for the not-uncommon use case of floating point numbers. With some projects I’ve been working with there is a lot …

Using systemd-resolved opens up some options that may be easier to configure then in the past. Enabling DNSSEC: systemd-resolve –status look for “DNSSEC setting: no” sudo mkdir -p /etc/systemd/resolved.conf.d sudo nano /etc/systemd/resolved.conf.d/dnssec.conf enter: [Resolve] DNSSEC=true sudo systemctl restart systemd-resolved systemd-resolve –status look for “DNSSEC setting: yes”
It’s not so simple as “cat /etc/resolv.conf” anymore. DNS is now handled by systemd-resolved in Ubuntu and Debian and their derivatives. This is easy to spot if you do check resolv.conf and it contains “nameserver 127.0.0.53”. The correct command now is “systemd-resolve –status”.
I’ve drafted but not published a long list of problems I’ve experienced with Ubuntu 18.04. In short it’s been one of the worst desktop releases of Ubuntu I’ve used. My experience on servers has been fine. Anyway I haven’t looked into the details of these patches but: libwebkit2gtk-4.0-37:amd64 (2.22.6-0ubuntu0.18.04.1) libjavascriptcoregtk-4.0-18:amd64 (2.22.6-0ubuntu0.18.04.1) These package releases seem …
I’ve often run a wired router at the front of my network (well immediately behind the modem). The only other topology has been a linux server at the front of the network. Then I like a network behind that where a wireless router can live. I keep my wireless router turned off when not in …
