Adventures in x86 ASM with rx86

December 22, 2021 | Jonathan Carroll

I just finished ‘Code: The Hidden Language of Computer Hardware and Software’ by Charles Petzold which was a really well-written (in my opinion) guided journey from flashing a light in morse code through to building a whole computer, and everything needed along the way. The section on encoding instructions for ...

March 8, 2020 | Jonathan Carroll

You may have seen the memes going around about fun ways to program the straightforward function isEven() which returns TRUE if the input is even, and FALSE otherwise. I had a play with this and it turned into enough for a blog post, and a nice walk through some features ... [Read more...]

February 22, 2019 | Jonathan Carroll

This journey started almost exactly a year ago, but it’s finally been sufficiently worked through and merged! Yay, I’ve officially contributed to the tidyverse (minor as it may be). I’m at least as useful as Zoidberg It began with a tweet, recalling a surprise I encountered that ...

Adding strings in R

October 5, 2018 | Jonathan Carroll

This started out as a “hey, I wonder…” sort of thing, but as usual, they tend to end up as interesting voyages into the deepest depths of code, so I thought I’d write it up and share. Shoutout to [@coolbutuseless](https://twitter.com/coolbutuseless) for proving that a little ...

JC and the Vignettes

March 6, 2018 | Jonathan Carroll

If that’s not a great 1960’s band name then I don’t know what is (hint: I don’t know what is). At the start of the year I set out my ‘goals for 2018’ just like many of us do; an overly ambitious list of things we’d like ...

June 2, 2016 | Jonathan Carroll

They say “if you want to find an answer on the internet, just present a wrong one as fact. Then wait.“ It didn’t take long, actually. Despite my searches while trying to get images into x-axis labels it seems I...Continue Reading →
