I’ve been on a nostalgia trip lately (again) for vintage computing. Luckily, most of the stuff I’m interested in is old enough that it can fly under the radar and be shared as the companies who created it have long since folded/merged as business entities or have stopped supporting the software altogether.
Interesting concepts here and relevant at today’s networking speeds: https://blog.acolyer.org/2018/10/22/legoos-a-disseminated-distributed-os-for-hardware-resource-disaggregation/

Occasionally I’ll have the need to watch screen output of multiple commands on the Linux CLI. Supremely easy but I don’t do it often enough to remember that I need to wrap the sequence in single (‘) or double (“) quotes. Correct formatting is below:
Great read – ~8K words and 25-30 minutes.
Occasionally, I have a need to delete and restart k8s pods after I’ve been hammering on a cluster, when I need to perform node maintenance, or when a project has run its course and I want to free up the namespace and/or resources. Below is a general overview of that procedure but note that it is specific to certain scenarios only and assumes you know the consequences of your actions. I do not warranty any of this!
My home Docker installation had some ports blocked internally for a project I was working on today. The sequence of commands listed below will allow the containers to communicate internally while still keeping open outgoing connection and not changing any incoming UFW rules.
sudo ufw allow in on docker0 sudo sed -i s/DEFAULT_FORWARD_POLICY=\"DROP\"/DEFAULT_FORWARD_POLICY=\"ACCEPT\"/ /etc/default/ufw sudo ufw enable sudo iptables -t nat -A POSTROUTING ! -o docker0 -s 172.17.0.0/16 -j MASQUERADE

I’ve been using email since 1993. Rather than simplifying and adopting some minimalist perspective regarding my email usage, it seems that I add another email account to the mix about once per year on average. One for whatever my main gig is at the time, my personal Gmail accounts, oh, and can’t forget that Yahoo mail account I’ve had since the late ’90s. Well, and then there’s the one side biz that needs its own server for legitimacy’s sake, yeah, and then that other that I still do contract work from occasionally…
You get the drift.
I still need to manage them. And as much of a FOSS geek as I like to be, I find myself getting pulled back to Outlook whenever Windows is my main OS.
Luckily, the process to add a new email account to Outlook 2013 gets easier to remember after you’ve done it a dozen times! Here’s the process I use:
