Increase swap size for your Raspberry Pi

I have a little low-end POC (proof of concept) I’m testing out at home before I bring it in to work. The POC requires my Raspberry Pi to run a couple of Docker containers which isn’t really a problem. However, I’m using a 1st-gen Pi that came out with only 512MB RAM total. By the time Docker itself was up and running, I had something on the order of 40-50MB of RAM left and another 99MB swap with the stock swap settings.

Rancher Kubernetes Engine (RKE) and chicken nuggets

I recently took a position as a cloud engineer with a small startup in the DC area. The startup is big on Kubernetes but we’d struggled to find a suitable framework for deploying fair-to-middlin’ sized clusters quickly on the private clouds we manage. I guess, to clarify: the deployments were completed in a reasonable amount of time, but the automated solutions we tried for initial cluster deployment just weren’t robust enough for daily production use.

Expect – an interpretive language in Linux

Expect is used to tie together multiple scripts or statements for which shell scripting is not quite powerful enough. From the man page: “In general, Expect is useful for running any program which requires interaction between the program and the user. All that is necessary is that the interaction can be characterized programmatically. Expect can also give the user back control (without halting the program being controlled) if desired. Similarly, the user can return control to the script at any time.”

SDF Public Access Unix System

I have fond memories of using dial-up BBSs in the early-to-late ’90s in Wichita, Kansas. Once the newfangled World Wide Web caught on, most BBSs went the way of civility and decency in today’s politics. It’s always a treat when I come across one that is still active in 2018 and even more of a treat when it’s been continuously active since the hey-days.

Super Dimension Fortress Public Access Unix System is one of those – thrivin’ and jivin’ since 1987.

Rather than have me recap what it is, just head over to it’s page at Wikipedia to get a glimpse for yourself. Then head over to their site and sign up for an account.
