Resample Archives

The archiver can now also be used to download the 1280 horizontal resolution resamples that are used by default on the site. Initially, this is limited to galleries that have 25% or more resampled files at this resolution.

Because of these changes, clicking on the Archive Download button for an archive you have previously unlocked will now take you to the archive selector instead of straight to the archive link, unless you have selected Auto Select Original or Auto Select Resample under My Settings.


Retired H@H Downloader

Since the archiver is now capable of generating a download with resampled files, the H@H Downloader has been retired. The addition of static ranges has made that suboptimal, and with resampled archives it also no longer has a unique function. Therefore, it has instead been replaced with a free archiver quota. (See below)


Donation/H@H Archiver Quotas

The old free archiver downloads for donators was changed from a fixed number of archives to use a quota based on archiver size. This also allows us to use this system for people who run H@H, to replace the retired H@H Downloader system.

For donators, each free archive from the old system now instead adds +50MB/day to the archiver quota. Tiers above gold were changed from +5 (250 MB/day) to +10 (500 MB/day) per tier. (See; Donation Archiver Quota in the MFP section below)

For people who run H@H, the archiver quota is now increased by +1000 MB/day for running at least one qualifying client, in addition to +10 MB/day per total adjusted avghit. H@H clients will only qualify if they have been running for more than 24 hours and have a hitrate of at least 1. (See; H@H Archiver Quota in the MFP section below)

Like the old system, the "daily" quota is measured over a 7-day window. You can spend up to 7 days worth of quota in a day, but you would obviously then have to wait a week for it to cool down.


Math For Pedants

Whenever we change from one system to another, there is always a heated discussion about the exact numbers used, so I pasted in the math and reasoning used below.

Donation Archiver Quota:

Average archive size calculated from 77215 files for a total of 3775 GB cached on one archiver:
3775 * 1024 / 77215 = 50.06 MB

H@H Archiver Quota:

Average size per resampled 1280x file sampled from a million files = 199156 bytes
Old H@H downloader rate was limited by each individual client's average hitrate, at floor(1 + avghits/25) files per minute, capped to 5
This gives 199156 bytes per minute per avghits/25 for 10.94 MB/day per avghit, plus 273.5 MB/day per client
Hard cap per client was removed. We instead calculate a global adjusted avghits from the sum of avghits for all clients on the account, set as min(avghits, log(1.003 + (avghits / 200), 1.003))
This is effectively a soft cap, linear up to about 300 avghits, increasing to ~600 at 1000 avghits and ~800 at 2000 avghits.
