Give me back my sanity

One of the many things I do for my group at work is to take care of automating as many things as possible. It usually brings me a lot of satisfaction, mostly because I get a kick out of making people's lives easier.

But sometimes, maybe too often, I end up in drawn-out struggles with machines and programs. And sometimes, these struggles bring me to the edge of despair, so much so that I regularly consider living on a computer-less island growing vegetables for a living.

This is the story of how I had to install Pandoc in a CentOS 6 Docker container. But more generally, this is the story of how I think computing is inherently broken, how programmers (myself included) tend to think that their way is the way, how we're ultimately replicating what most of us think is wrong with society, building upon layers and layers of (best-case scenario) obscure and/or weak foundations.

*I would like to extend my gratitude to Google, StackOverflow, GitHub issues but mostly, the people who make the

# The following assumes a default Alpine install using the standard Alpine image

# Note: for VirtualBox, you could be tempted to use the `alpine-virt` image,
# however it uses the `virtgrsec` kernel, for which there is no guest additions support

# if required, SSH root password access can be enabled by adding `PermitRootLogin yes`

Mental Games

It'll come as no surprise to anybody here that the human brain is pretty amazing, and I often wonder how far it can be pushed, or how much control you have over it (or your body by extension). I won't get into any metaphysical considerations here or anything like that, I'd just like to share something I do quite often and hope other people share too.

As far back as I can remember, I've been making up and playing mental games with myself. I didn't really do it consciously until I was maybe about 7 or 8, but as of today I still do pretty much all of them. They generally take no more than a few minutes and I think they're quite an interesting way of exercising your mind and figuring things about how you work.

I'm not sure whether this will come through as absolute lunacy or total stupidity on my part, but this isn't something I've ever seen discussed and I'm genuinely interested in it.

Here are some of my favorites:
