You may have to either pause when you need to cough and sneeze or just edit that out. I am interested in this topic but the horrible quality of audio video made me puke.

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 am interested in this topic but the horrible quality of audio video made me puke. Sorry. 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.

Probably should edit out such non-sense. Yah, my next question would have been: How do you intend to have a self hosted C compiler handwritten in pure D? :)

It is called cat, and come out of the box with any UNIX like system. Just so happens to be compatible for D to D compilation too. This tool is awesome!¿?¡

So I can compile C+x where the X is whatever is needed to get it self-hosting.

Hi, how about using PEG for parsing etc.? IMO that would be a very good showcase for the power of PEG And D. -- Robert M. Münch http://www.saphirion.com smarter | better | faster
