Post by my nameThe binary groups have (maybe had now?) a 15mb limit for uploads.
It's "had"--very much so. You can post most any size binary you want to
Usenet now, and very few decent servers will choke. In fact, with the
advent of PAR2 recovery files, RARs don't make sense on Usenet anymore.
Better just to create the parity files from the video file directly, then
split the file with a file cutter. (Splitting isn't even strictly
necessary, but it does have benefits for some servers.) That way, if the
post is too fragmented for recovery, you can still stitch the (broken)
pieces back together into a broken file. Load that into a torrent
client, and the torrent client will download just the parts that were
corrupted on Usenet.
You can't do that with a split RAR archive, since extraction can't
progress past the first broken volume. And even if someone else has the
same original file, they can't recreate the one RAR volume you need a
repost of. (The *.SRR files posted by the "scene" attempt to fix that
issue, but there'd be no issue in the first place if they didn't use
RARs!)
On the other hand, suppose the file was posted directly without RARs. If
I downloaded the file through bittorrent, and I see that the Usenet post
is broken beyond repair, I can create additional PAR2s and post them.
They'll work right alongside the original PAR2 set. This would be
especially useful since the "scene" doesn't check it's posts to Usenet or
respond to requests for more PAR2 files--and those on Usenet who DO read
such requests aren't likely to have the original RARs.
Post by my nameA person encodes the show, then breaks it up into rar files, which
makes it easier and faster to move to another server where it is
shared. If one piece is broken, you only download another small
section instead of redownloading the entire part. That continues to
make sense today as there are still places in the world that have data
caps. It's much easier to redownload a 15mb file than a 350mb file
when you've got caps.
This is true, but PAR2 recovery files make it even easier. Instead of
15MB, you might only need to download 500KB, or whatever the parity block
size is. And you wouldn't have to store the parity files; they can be
recreated by anyone with the intact file, whenever they're needed.
Really, since PAR2 became available, RAR only makes sense as a way of
bundling many small files together. For transferring single large media
files, RAR should have long since been abandoned.
But good luck getting the "scene" to accept that. Their L337 5K1LLZ
probably aren't going to listen to something as mundane as logic...
