remember that site you loved 10 years ago? probably gone.
a huge chunk of the web from 2013 doesn't exist anymore
tape create --immutable
tape deploy ./dist/index.html
two lines. site is live and nobody can take it down

what does it cost to make a storage node hard to knock over?
the @tapedrive_io nodes are getting a front door.
XDP at the nic. TCP-AO sealing the peer port. admission inside the node. a thread per core gate on io_uring.
every layer from the wire to the request, measured against the bare node.
every microsecond counted.

first layer measured.
mutual tls between @tapedrive_io nodes, ed25519 certs on both sides, cpu per handshake:
rustls + ring: 180 µs
rustls + aws-lc-rs: 142 µs (has post quantum ML-KEM-768)
boringssl: 169 µs
one provider swap, 27% more handshakes per core.
fyi, same setup on agave today. 👀

two layers we're adding in front of every @tapedrive_io node:
- sieve, an xdp filter in the nic driver, drops abusive packets before the kernel sees them.
- frontdoor, inside the node, lets peers in first and limits everyone else.

It's been a *long* time since I last touched the storage allocator. This time the goal was to ensure storage nodes with varying raw capacity could participate in the Tapedrive network.
This is a big one for adoption, and I'm hoping to allow way more of you to participate.
We're going to roll this out to devnet sometime soon

the one who falls in love with the journey, will always go further than the ones who focused on the destination.

exact design of reel store. out-of-place by construction. 👀
If you're interested in SSD internals and how to use them efficiently, our paper, “How to Write to SSDs,” has been accepted to VLDB and is currently on the Hacker News front page. vldb.org/pvldb/vol19/p1469-l…

My teen daughter came up with what might be the most ambitious NFT challenge ever.
She wants to start with a worthless NFT and trade her way up to a CryptoPunk.
Wanna be part of the story? Help us spread the word 👇

I'm so excited to share this NFT experiment with you.
A challenge to trade my way up to a @CryptoPunks
Starting the journey with a rugged NFT, shooting for the stars. Will i made it? idk but i will make my best effort.

This weekend we rolled out a new major release for Tapedrive on devnet.
Several new features bundled into this release:
- Whirlwind (our challenge mechanism)
- Reelstore (our rocksdb replacement)
- A slew of performance improvements (5x-10x better all around)
This is our "alpenglow"
