  2. What an honor to see this here! Should I have known I would have done a better and shorter demo. This link appeared on the last slide of the IISW presentation and intended to elaborate on the DNL glitching on every 16th code, as the 9-minute presentation slot was not enough for this.

    Anyway, thanks Vladimir for posting it.
