I will shoot the next videos when I am healthy again. I thought about writing the code beforehand, and then just go through and explain it. What do you think of that ? @ibuclaw You did not misshear, I really said that :( . I was referring I to the fact, that I do not parse uppercase letters atm. Probably should edit out such non-sense.

Yah, talking ad-lib is not fun, nor an easy thing to do. 1) Script your presentation, making notes of the time it will take for you to talk through each section. 2) Screencast without audio, following the script to your timings. 3) Get yourself a Zoom H1, and record the audio over the video. It *is* the season to be sick and bunged in. But that's not a good excuse for spending 15 minutes sneezing and coughing your way through a pre-recorded talk. :-) By the way, on a more technical note, I was confused by some of your comments, such as not using camel casing and D's foreach because it makes self hosting difficult? Maybe I misheard, but it seems absurd to my ears, but then what do I know. :-) Iain.

I don't know... in 720p I can't complain about the text but on the otherwise in 480 is really a bit fuzzy. Well as a suggestion I think you could expand the window where you are writing the code. Or even focus entire on it. I'm waiting for more videos. :) Matheus.

Plotcli: Plotting from the command line
Plotcli is a command line application (written in D) that can create plots from text/csv files and from piped data, making it useful during data analysis. Plotcli works best in combination with other command line tools such as awk. Plotcli will ignore any lines it does not understand, so it is safe to use with files that contain non csv data as well. Typically I use it during simulations, where I simulate data, which I pipe to a file and then I plot it using plotcli: plotcli < path/to/file It will plot the data and save the plot to a file (by default plotcli.png). Plotcli has a command line switch similar to tail (-f) so that it will keep checking for new data until it is killed with ctrl+c. Plotcli is meant to be adaptive and will automatically adapt the plot boundaries to encompass all the data. https://github.com/BlackEdder/plotd

But of course, if this is a PoC that D Caen be used to write a full compiler to output machine code then LLVM's off... I want to do a C backend first. Building an LLVM Backand out of that is a small step.
