Learning Kubernetes, Setup Notes

Ok, here’s to learning Kubernetes in earnest, to get that career pivot going. Notes as I learn, over the coming days. This one, is a lot of random thoughts on bringing up a cluster. It is both harder than you think, and easier than you think I did this, because I wanted to run my own cluster, just like the big boys do.1 It’s much easier to run alternatives like kind, if that suits your needs better....

Make KVM Use a NIC in Bridge Mode

I wanted to start learning Kubernetes. So I thought I’d spin up a Ubuntu VM to use as my sacrificial guinea pig. While the normal NAT mode works well enough for most of my networking needs, I wanted the Ubuntu VM to show up and work as a machine on my host’s network.1 I have two network cards on my desktop and wanted to allocate one of them to this VM....

Make SSH Ignore Key, When Logging On to a Fresh Box

Every now and then, I spin up a fresh vm. And being a creature of habit, I use the same username on my play / experimental vms as my normal login. So everytime I try to login to such a vm or pi, I get a Too many authentication failures error. So to just get in and start working, I need to tell ssh to ignore my keys and try using passwords as the authentication mechanism....

Notes to Self, on Self Hosting Fonts on My Hugo Blog

Writing this down, so that I will not struggle the next time1, I have to do this. I use Valkyrie for everything on the blog in various weights, except for code and preformatted stuff, which uses Source Code Pro Medium. Both are WOFF2 fonts. Anything in Hugo’s assets/css/extended folder will be picked up by Hugo and bundled into a single CSS file. The fonts are in subdirectories in the static/fonts/font-name folder....

Exclude Files and Folders From an Rsync Copy

I’ve been sticking to plain old rsync -az to sling files around using Rsync. Until I ran into a hiccough today, where I filled up my teensy remote storage on the Pi, because a couple of subdirectories that were part of the run, were hundreds of megabytes large.1 So I did the usual, did hunt around the web thing, and learnt about --exclude So now the new Rsync command is …...

Rename a File as You Work on It in Emacs

I often fat fingered the file name / buffer name / Org Roam link name when launching something new. And then when I am busy and knee deep in work, I glance up to see the error glaring at me. I figured out, looked up how to fix it Hit C-x d to flip into a dired buffer Find my filename in the list. (C-s can help search and narrow stuff) Then C-x C-q to go into Wdired mode Change the file name to whatever I want it to C-c C-c to be done with it....

Moving Tasks Between Org Files in Emacs

More diving into Org Mode and Emacs. I have a stuff-to-do.org file, that serves as an inbox for most long term tasks that I want to tackle. Stuff that needs doing, books that I want to buy, books that I want to read, courses that I want to learn, movies or tv shows that I want to watch, stuff on the web that I want to catchup on, etc. etc. etc....

Notes to Self on Renewing Wildcard Certbot Certs

After struggling to renew my certs for the third time in a row, hopefully these pointers should keep me on track for the next time. Namecheap does not yet support automatic wildcard renewal for the Letsencrypt/Certbot combo. Check next year. Have your Namecheap control panel open and ready. Command to renew: certbot certonly --manual --manual-public-ip-logging-ok --preferred-challenges dns-01 -d *.domain.com -d domain.com You normally run this as root certbot will then, print a couple of lines that you need to add as a TXT record in the Namecheap DNS control panel....

Tomorrow is Another Date

Org mode is slowly spreading its tentacles increasingly becoming something, I cannot live without, to manage my day. And I’m getting pretty consistent with it too! Like you see above, I use dates as my headlines, below which I list the various tasks for the day.1 And that’s where I run into my current itch to scratch. I don’t want to keep typing out the date daily. The computer can do that for me....

Emacsclient Does Not Recognise Compose Key Sequences

Originally published 2021/10/27. Updated to include the .xssessionsrc point I run pretty often into this issue, so this is a checklist for me. Issue being, that I cannot use Compose key sequences to type out the characters I need. Case in point being, the apostrophe ’ and the quote marks “” , ‘’ that I use, all the live long day. Make sure that emacs is running as a service. It runs in your user, so check status with systemctl --user status emacs....
