I see the need for home automation. Well…I would like to explore this technology and make it work for me. There are so many options and there are some very expensive options, not just cost but in privacy and closed ecosystem risks.

Upgrading MacOS from High Sierra to Mojave introduces some new security requirements that cause issues with some applications. The fix for apps created in electron is simple onse you know how.

My hard drives were spinning at 7600 RPM 24/7, this is fine for aa actual server for the masses or in DC, but total overkill for my intermittent needs. Why do I want power control over my spinning rust…spin down to save noise and heat = save energy.

Always use the graceful method unless absolutely necessary.  i.e don’t just yank the power cord out. There is console less method and a CLI method over the network

how about a smoking network I’m redoing my home and lab network with the goal to go 10Gb/s. Let’s up that and go 40Gb/s and while were are at it let’s take it even further with 56Gb/s….with a twist. I found Infiniband hardware cheaper then ethernet and it can do both

IPMI is more then a way to access servers over the network without them powered up (lights out, out of band etc). It is an Intelligent Platform Management Interface, it can be used to interface with the hardware layer in ways the OS can’t. Let’s use it to control some fans.

dd has being my go to tool for “everything-imges-and-iso”, especially ever since the usb stick became ubiquitous and norm for installing new a OS. There is a new kid on the block now…but it needs a GUI.

The new trend in linux is the shift to netplan as a network manager that uses either NetworkManager or systemd-networkd to manage interfaces is pretty much the default now for Ubuntu Desktops. This breaks OVS and linux bridging, but there is a way

Continuing on with my theme of compiling and patching linux kernels. Let’s look at the Ubuntu way that creates a .deb file for use with apt package manager. Git work flow thrown in for free.

As we have seen, the original/traditional/generic way to install new kernels or patch existing kernels is a relatively straight forward affair but requires manual management. Let’s use git to help
