A reader called Kuno notes that there are now some good Russian-English dict-format dictionaries available online. They are very likely better than the ones I extracted a couple years ago. The dictionary files suggested by Kuno can be downloaded directly, fetched with rsync (
rsync rsync://dictd.xdsl.by/dicts/) or the server can be queried with a dict client (try "
dict -h dictd.xdsl.by -D" for a list of available dictionaries).
