System(d) upgrade
I have recently updated a server of mine from Ubuntu 16.04 LTS to 18.04 LTS.
As usual, it was a bumpy ride. The upgrade stopped half-way through with my
system in a stupid state, and I had to figure out how to fix things so that
apt would be able to continue the process. I don't understand why this keeps
happening when the resolutions are so daft. This time it amounted to removing
a good deal of packages with dpkg. I don't understand how it is valuable
that I do this myself – it's not as if I kn…

I'm experimentally adding a blog to this site. In this post, I'll introduce
the blog and discuss some specifics about how the blog and site in general is
technically put together.
I used to write a bit on Google+, but it is neither a good blogging
platform nor a good social platform, so I have given up on that. Writing blog
posts on this site is technically superior, and I suspect I will get a bigger
audience posting them on Twitter than I got on Google+.

A lot of people will recognize this…

This post was originally a featured article on the front page. I thought
the technology looked fun and promising, and I wanted to keep up with it. It
is clear, however, that the winner in this space is WASM, and PNaCl is just a

what I want the fetaured articles on my front page to be like, so I relegated
this text to the blog on 2019-09-09.
We will develop a minimal PNaCl
module with a focus on exposin…

This was originally posted on Google+, which has now been shut down. It was
helpfully converted to Markdown by Robert Jacobson after which I adjusted it
for reposting here. I have dated it at its original posting date, but it was
posted here on 2019-09-07.
Since the last time, the nasm people have been able to fix the bugs I stumbled upon, and pushed them in a release.
Anything newer than 2.10.6 is probably also fine. Please note that you have to update if you are following this tutorial on OS …

This was originally posted on Google+, which has now been shut down. It was
helpfully converted to Markdown by Robert Jacobson after which I adjusted it

At this point, we are tired of the line-buffered interface. Let's make it more responsive!
Step 11: Cleanup
First, let's just clean up our code a bit by putting our constants on top:
