On cable channels you’ll find loads of “documentaries” breathlessly telling you about supervolcanoes and how Yellowstone is going to kill everyone. Possibly also involving aliens.
So it was nice to see this public lecture on supervolcanoes and what they actually are (and are not), their history in the Pacific northwest and the science behind it all. It’s an hour and a bit long and makes for a good listen on a lazy weekend morning.

I’ve converted code repos a number of times through my career. From cvs to subversion, from subversion to mercurial and git, from mercurial to git. However until the other day, I’d never converted from cvs to git directly.
In this case it was converting an old CVS repo I’d found in some old backup cdroms which were being tossed out.
It went well but there were a few hiccups. First there are a number of methods to do this.

My first attempt at Cheez-Its went ok, but they were
too dense. Looking at the official recipe I saw it called for yeast. So
I looked for a recipe that used yeast and found this one from
Serious Eats. As always I tweaked it a little. Currently on
step 5, so should be interesting to see how they turn out!
Like quite a few Galway geeks it appears, I queued up early to see Avengers Endgame.
Queuing for Endgame This was taken around 10pm as we waited for the one past midnight showing. For once I walked in pretty unspoiled and it was well worth the wait. I can’t go into what I liked without spoilers but can say that I was surprised, I laughed a fair bit, I teared up and was just plain wowed in parts.

Thanks to mpk today I learned that vim can work with scp “urls.” So vim scp://remote-host/kittens.txt works kind of as you’d expect. It can edit existing files - and for zsh tab completion will work here - or completely new files.
By default it’s going to edit files relative you your home dir - you’d need to do a double slash to edit a file from the root dir.
In the new site design I wanted a subtle and simple tag cloud. I initially did it by ordering tags in the footer by how common they were. However alphabetical order exists for a reason, so it was clear that wasn’t the best choice.
Tag clouds normally show popularity with font size. Not being a huge CSS person, I hadn’t realized font size was another thing you could specify relative to everything else - but you can!

I use gandi for all my DNS needs and while I used to run my own dns it got tiresome after a while. So a long time ago I switched to using gandi to do it. Back then they had an api I was able to manipulate rather easily with python.
But a few years ago they changed to a new api and I put it on the long finger to migrate over.

OpenSSL 1.1.0 introduced some incompatible changes for symetric encryption. I use it for some code repos to store secrets in lieu of other options. It works just fine for a single developer, but obviously doesn’t work very well beyond that.
Recently those projects started breaking and I wasn’t sure why. The commands I used to encrypt and decrypt were, respectively, as follows:
1 2 3 4 openssl enc -aes-256-cbc -pass "pass:$SECRET" \ -in .

In Google there was (and possibly still is) a tool called “sourcerer” that let you browse through a repo. One nice feature it had was that deleted files and directories were shown struch through in red - and you could even follow down deleted dirs.
I’ve long wanted that view of a git repo. And today while digging through a rather old, imported work project it turned out that was useful to have.

I’ve mentioned before this is a static site so how is it there’s now a search function. The magic of javascript!
I’d seen a search box on hugo sites so I looked around and found these two articles 1 2 on adding search and they each built on each other using lunr.
I tweaked the index building to try and squash it down a bit. The javascript I use to build the lunr prebuilt indexes (search/index.

I was reminded of this article which is a nice little example of how to use shell tools in Unix to solve problems faster than if you were to “write a program.”
You’re still coding in shell, it’s just that each “line” is a pretty powerful function. Plus each function has a pretty simple interface: it will take a text stream and some positional or named arguments and it will produce two text streams (one is usually “the output” and the other is usually an “out of band” stream) and an integer.

A further update to my original and updated retirement posts.
Since I last wrote on this topic I chatted with two pension plan advisors in the course of setting up my company pension. One interesting thing I learned is that for the best tax benefit for an Irish pension, the goal is a €800,000 pension account. You can withdraw 25% tax-free up to a maximum of €200,000.
As a US citizen who is also subject to US taxes - which do not recognise 25% tax-free withdrawals of pension funds, I’m not clear what the consequences are.

This year it seems that everything that was ticking along just fine is suddenly breaking. Which is annoying. This week was a home git mirror.
My network connection is, at times, rather slow. Sometimes it even disappears. It’s therefore kind of nice if I have copies of code bases locally. I have a script that does this just fine and it’s worked for years.
Starting this year it started to bog down the server I ran it on.

Read the tig manual a bit more after my last post and it turns out there is a way to checkout older versions. Just put this in your ~/.tigrc:
1 bind blob C !git checkout %(commit) -- %(file) That binds C in blob mode to the command to check out that version of the file. The one downside is that it puts the file in the index so you need to do a git reset -- FILE to take it back.

I’ve been looking at ways to view the commit graph in git in a terminal because FreeBSD doesn’t natively package the gitk tool. This is annoying because it’s a nice way to show new git users what’s happening when they do merges.
Coming from older VCS tools, merges are scary. They’re really not scary in git if you know what’s happening but if your experince with merges is subversion or, worse CVS, you’re going to get twitchy about a merge.

When working in a git repo with lots of people a frequent command I’ll use after a git fetch (note, not a git pull since looking before I leap is wise here) is git g. That’s defined as:
1 2 3 git config --global alias.g \ log --graph --abbrev-commit --date=short --all \ --pretty=format:'%Cblue%h %Cgreen%cd %an%Creset -%C(yellow)%d%Creset %s' This way I get a quick view of who committed what since I last was working on a branch.

Got an email to my gmail address today. It’s a common-ish Irish name so I occasionally get odd emails to it.
Good Morning,
Your child was selected to participate in the Half-Day UPK Program for the 2019-2020 school year and has been placed at School Time Children’s Center (Coldenham location). Please read the attached letter/registration appointment schedule for details about registering your child.
It went on to give instructions on how to register my child.

I’ve maintained my shell startup files by hand for ages. First for tcsh and then for zsh.
But the kids today seem to have come up with some nifty ways to do this. Things like oh my zsh (omz), antigen and zgen. They provide some nice tools for configuring your shell in a plugin type way with lots of nifty ideas out of the box. There are some other ones as well - presto and zplug for instance - but I just dug into these three.
