I re-ran the same secret-extraction attacks against the flagship models. Gemini 2.5 Pro folds to a forced schema 95% of the time — worse than the cheap tier — while Claude's flagship models drop the prefill surface entirely. The holes move between generations.
Gemini leaks under a forced JSON schema; Claude resists that but folds to prefill. Opposite weak spots, same secret — and one deterministic defense that catches both.
Six hand-written jailbreaks couldn't crack my hardened bot. Then I forced its reply into a JSON schema and it leaked the secret on turn one. Why structured output is the hole.
I built K.E.V.I.N.: one AI tries to extract a secret from another while three judges score each attempt. Three things 50 rounds of automated jailbreaking taught me.
I'm retiring Sonogram, my WebGL music visualizer. The audio analysis underneath it — waveforms, EBU R128 loudness, key and tempo — lives on in 1-bit. What I kept, and what I let go.
1-bit — the bit-exact DSD and PCM player for iOS — now has its own site at 1-bit.app. Here's what moved off ars.md, what stayed, and why the split made sense.
Two ways to play music from an iPhone into a Chord Hugo 2 — a USB cable, or UPnP to a 2Go bolted onto it. Both are bit-exact. Here's what actually differs, and which one is optimal.
How to play music from an iPhone to a Chord 2Go over your own network — bit-exact, no transcoding — using DLNA and a self-hosted 1-bit bridge. Plus the security caveat nobody mentions.
iPhones don't play DSD out of the box, and most apps quietly convert it to PCM. Here's what actually playing DSD takes — a USB DAC, DoP, the right file, and a player that gets out of the way.
1-bit 1.5 is on the App Store. Play bit-exact to a Chord 2Go or any DLNA renderer on your network, back up your playlists to your own bridge, and keep a private listening history. Bridge 0.1.5 ships alongside with a DLNA MediaServer. Same DSD over DoP, no transcoding.
