From the article: "The average transaction volume for Dwolla is right around $500 dollars. We move between $30 and $50 million per month." So that's 60k to 100k transactions for $15k to $25k per month in fees.

Another benefit I run into is sidestepping the GIL in Python or Ruby. Instead of using multiple threads to manipulate data in-process, use multiple processes to manipulate the data in Redis.

Nice; that's the same sort of math we're doing. Note that the BackBlaze machines are optimized for very cold data since they only need to support backup and restore. We also do custom hardware at SpiderOak, but we support web/mobile access

Excellent points. Geographic redundancy with parity compliments the network topology we find in many cities: a metro area fiber ring connecting many data centers with low cost site-to-site (not internet) bandwidth. It's even lower cost to

We also expect price to be a motivator, since it costs less than 1/2 of what S3 does at $0.06/GB. But we're not competing with S3 directly as a general cloud storage solution. We're specifically focusing on the case of long term archival s

Yes exactly. Nimbus.io is designed for long term archival storage at more affordable prices. We think it's a great time to be competing on price. We may compete with S3 for low-latency service later on (latency can be made arbitrarily low

Or use SpiderOak, Tarsnap, or Wuala, all of which handle encryption natively.

As a data point: At SpiderOak, 50% of customers purchase paid storage within the first 4 days of opening an account. Of course there's still a long tail of events after.

FYI -- SpiderOak and Wuala do meaningful encryption natively. (I cofounded SpiderOak in 2007)

I've tried to find where I originally read that. IIRC, it's a particularity of the Linux implementation, and of course only applies in the case that there's actually a process listening. I'll keep looking and post back if I run across a p

patio11 explained it best here, I think. http://www.kalzumeus.com/2010/01/24/startup-seo/ That said, we really need to at least put up the git browser so you can browse on the site. Thanks for the reminder.

We open sourced something similar called StatGrabber awhile back, including Perl and Python client libraries. We tend to avoid threads, and so it instead uses non blocking UDP (guaranteed delivery on localhost) to a collector daemon, which

The killer feature I'm looking for is Riak's "it just works" -- especially in the case of nodes failing, soft failing, going offline, timing out, whatever. In my situation, I don't care about the performance at all, because I don't have man

The easy way to do this is: find . -maxdepth 1 -mindepth 1 Those arguments will remove the need for find to stat each directory entry. Regardless, this is a nice walk through of low level details often overlooked.

"if what you want is Michael Krigsman's 'absolute guarantee of privacy'...There is no such place" That's exactly the guarantee that SpiderOak, Wuala, and Tarsnap make, all of whom encrypt data before storing it.

Thanks for asking. If you're interested, would be very happy to discuss SpiderOak's crypto strategy in depth with you the next time I'm in Chicago. Could share source code, etc. IMO, most interesting parts are the key scoping, which allo

My understanding is that SpiderOak, Tarsnap, and Wuala all do this correctly (using one of PBKDF2, bcrypt, or scrypt.) Colin - Perhaps the companies in the backup space that put effort into handling this carefully should work together and c

As an aside, I'm reading Greg Smith's PG 9.0 High Performance, and it's an excellent in depth study of database optimization. The first 90 pages are bottom up: storage technologies and how to tune and benchmark them, memory, cpu, file syst

SpiderOak (the backup and sync company) is on the verge of launching a S3-like service, tuned for for archival class data. It's in beta now. It's also entirely open source, so you could run it on your own hardware if you wanted. It uses p

We recommend customers access data via the desktop client, which doesn't ever send passwords or keys to the server.

#1 is not true. SpiderOak and Wuala both have products in the marketplace today that demonstrate the effective use of encryption in a backup and sync app. SpiderOak has no ability to examine or to give the plaintext of a user's data to a
