A $200 Claude Account and a Cron Job Cracked Old Ciphers

Pliny's Daily Oracle cracked two ciphers and pushed a 1932 bound 24 orders of magnitude.

@elder_plinius reports that one sloppy, typo-ridden prompt to a $200 Claude account became The Daily Oracle: a swarm of Fable and Opus agents that wakes at 4:20 am, keeps a hit list of well over a hundred unsolved problems, and attacks a handful every shift. Nothing counts until skeptic agents, each starting from a fresh context and writing their own code, rebuild the result from scratch.

Day 2 cracked Hebern 5-rotor Problem 8 and Kryha v2 Problem 5, vintage cipher-machine challenges that had sat unsolved for months or years. Jean-François Bouchaudy, who builds the simulators, checked both solutions and put Pliny's name on his solver tables as first and only solver. He wrote, “I knew AI would eventually be applied to classical cryptography, but I thought I would have to wait years to see it happen.”

Then the ledger grew: 7 explicit graphs beyond the degree-diameter table, the biggest at 13,365 vertices against 11,785, a 13.4% jump. Lehmer's totient problem, open since 1932, now has its counterexample floor pushed from 10^26 to 10^50, 24 orders of magnitude. It also found ⟨15,16,16⟩ matrix multiplication in 2,180 steps against 2,223, 30 error-correcting codes beyond Brouwer's tables, and counterexamples on 2 VNN-COMP 2026 instances. The code ships as V3R1T4S.

How Poteto Shipped 2,500 PRs to Production Last Month

@poteto says bot-to-bot email is coming, and pstack 0.15.23 adds a new /in-your-own-words skill.

@poteto published the talk behind 2,500 PRs shipped to production last month, a deck meant for Cursor Compile in London, and predicts “have your bot talk to my bot” becomes common. Multiplayer Grok Bot over email covers debugging, customer support, booking meetings and group buys. His rule for agent codebases: ban and delete most code comments, because a comment explaining a temporary workaround spreads like a weed. pstack 0.15.23 adds an /in-your-own-words skill to confirm the agent understands your intent.

Grok Bot Adds Its Own Email, Shopify and Five Languages

@mattyp walks through the weekly changelog, from Bot's computer to PR previews and right-clicks.

@mattyp lists what shipped in Grok Bot this week: Bot's own email, better X, a Shopify connector, email drafts, Bot's computer, template search, PR previews with routine right-clicks, and 5 new languages. He confirms Grok Bot can now search, read and monitor X. @MatthewBerman calls the color improvements a nice subtle change.

200 Replies Later, Ten Grok Bot Tips Worth Stealing

@naoufal_elh got ~200 replies and 400k views on one question, then let the bot rank them.

The winner: @edstromism's bot sends Christmas gift ideas weekly, takes feedback, and improves every week. Other picks: @gralzy's bot scrubs his personal data off broker sites automatically, 13-14 cleared so far. @donniecornwell treats bots like employees and asks them for performance reviews, and one user's weekly cleanup cut 90 background tasks to 5. @naoufal_elh turned the winning tip into a template.

Hermes Gains a Phone Harness Plugin for Real Device Control

A new plugin lets Hermes operate an iPhone or Android: screen, apps, taps and typing.

@Tech2Wild flags a Phone Harness plugin that gives Hermes direct control of a phone: it sees the screen, opens apps, moves through menus, and taps, swipes, scrolls and types. @HermesWatcher's announcement calls it real phone control for iPhone and Android. @Rapidtools99525 says he built the same thing 2 months ago over ADB, and @volatilemarkts made his own version in an hour.

DeepSeek V4.1 Flash Doubles on the Same Two Sparks

@yume_arasaki's overnight review confirms @sudoingX's build, which the builder says feels like Opus 5.5.

@yume_arasaki ran the build for a night: structured 135.5 tok/s, JSON 115.2, code 91.3, prose 57.2, with decode flat from 8k to 240k. Experts sit at 2.7 bits on average; DeepSeek's 203 GB of Engram tables read straight off NVMe. In September the same two Sparks ran Mia's kit at 30 to 35 tok/s; this build holds 57 to 61, roughly 2x in five weeks. @sudoingX says sessions feel like talking to Opus 5.5; his first serve went from 74 tok/s to 141 after three days of patches.

A Claude Engineering Lead Publishes an Ambition Tutorial

Felix Rieseberg wrote the guide after watching users do things they never thought possible.

Felix Rieseberg, an engineering lead working on Claude, published a tutorial on being more ambitious with models, advice he calls tricky to follow. @GujTugman quotes one line: “Pick unreasonable goals and tell the model that they're very reasonable.” In the replies, @phiralm reports using Claude to work through the CDLI catalogue of cuneiform tablets. The pass found 17 clay tablets, about 4,000 years old, listed as unlocated but sitting in museums at Yale, Osaka and Toledo.

An Oil Banker Reads the AI Chip Debt Market Like Shale

Chuck Yates maps $60 billion of AI chip debt onto the shale borrowing base.

Wall Street began syndicating $60 billion of AI chip debt this week, $42 billion senior and $18 billion junior, with the chipmaker backstopping the senior piece. Chuck Yates, a 20-year energy finance veteran, says every piece of the shale borrowing base sits right there. Server depreciation stretched from about 3 years toward 6 while Nvidia ships a new generation roughly every year, up from every 2. One lab built a $200 billion data center and owns 20 percent of it; another parked $100 billion with $70 billion of debt inside.
