Monica Terenghi is not. She is participating in the subtitling of this video as an activity of Laboratorio di tecnologie internet per la scuola #LTIS13 , a Italian University Line workshop for teachers about using internet technologies in schools, organized by Professor Andreas Formiconi .
This is the second of Professor Formiconi's online workshops for Italian University Line where I set up a subtitling activity for the participants who request it, and use Amara for it. Last time no one did any upload or rollback in the videos we were working on, but unless:
this is the last time I use Amara for such an activity with teachers.
When a set of subtitles is updated by upload, or object of a rollback - or even when existing subs are resplit differently, a bug in the Amara software sometimes replaces other sets of subtitles by an "uploaded" revision, and deletes the content of their former revisions.
Instances of this critical issue have long been reported in help forums. So:
Some reported instances
BUG in subtitle uploader reported by Ambrose Li on March 22, 2012 (on the former help forum, when Amara was still Universal Subtitles):
Can't add a new translation reported by me (in the second comment starting with "Curious variation of the uploading a translation problem") on Aug. 12, 2012, but incompletely as it was my first encounter with the bug, and back then another issue with uploads complicated understanding. Actually, based on the video's activities page 3 :
History of revisions messed up by the software reported by me on August 27, 2012
If 2 original subs are merged, the translation of the second disappears - and former revisions of the translated subs are destroyed reported by me on November 5, 2012: this is a particularly worrying case, as the bug was triggered by simply merging 2 of the English subtitles, not by a rollback or by an upload
A roll back destroys Spanish subs and messes up most other subs for PSY's Gangnam Style video reported by me on Dec 23, 2012
Mixed up subtitles reported by Anna Röing on March 26, 2013
Chickarama's request for deleting some subtitles presently on p. 6 of Reply here to request to Delete a video or Remove subtitles on March 28, 2013 (archived in http://www.webcitation.org/6FTrk3SNT as the relevant page and its URL might change as further requests are made)
NB though Chickarama was not aware of the rollback-triggered bug when she posted that request, she has confirmed off-forum that this was the cause of the problems she describes in that request; she has also reported the issue via a ticket.
