| 1. | I've factored the RSA keys of a Certificate Authority from the 90s(mcpherrin.ca) |
| 487 points by ahlCVA 2 days ago | 123 comments | permalink | |
tl;dr: The author factored two 512-bit RSA root CA keys from the defunct Canadian CA "E-Certify" that shipped in Netscape 4.51 in 1999, using CADO-NFS on a Ryzen 9 5950X in about 30 hours each. They also cracked a 512-bit VeriSign test code-signing CA from IE 3.02 (done on GPU in ~1 hour). The recovered private keys, tools, and a demo TLS server compatible with Netscape 4.51 are published on GitHub, illustrating how weak early Web PKI standards were even by contemporary cryptographic norms. | |

tl;dr: Mistral raised €3B in a Series D at a €21B+ post-money valuation, led by Samsung Electronics with EQT's Scaleup Europe Fund and PSG Equity — the largest equity round ever for a European tech company. The funds will expand frontier research, compute capacity, and international growth, positioning Mistral as a full-stack "sovereign AI" provider offering open-weight models, infrastructure, and products to enterprises and governments seeking control over data and deployment. | |

| 3. | TALA Is Open-Source(d2lang.com) |
| 304 points by alixanderwang 2 days ago | 23 comments | permalink | |
tl;dr: Terrastruct has open-sourced TALA, its autolayout algorithm for software architecture diagrams, under MPL-2.0 and bundled it into D2 v0.9.0 (usable via `--layout=tala`). Unlike Dagre and ELK, TALA is an orthogonal layout engine optimized for whiteboard-style diagrams and supports custom or partial node positioning—useful for AI-generated diagrams where models place nodes but struggle with routing. Tradeoffs include nondeterministic-feeling output when inputs change, weaker DAG handling, and nonlinear runtime scaling on larger diagrams. | |

| 297 points by saikatsg 2 days ago | 336 comments | permalink | |
tl;dr: A speculative near-future scenario (referencing fictional models like GLM 5.3-flash and GPT-6 Astra) argues that cheap, open-weight LLMs with safety guardrails removed will soon enable anyone to run automated cyberattacks against real infrastructure for the cost of a consumer workstation. The author urges urgent action: governments should mandate and fund pentesting and patch deployment, while companies should hire security engineers, use frontier models defensively, invest in supply-chain security and memory-safe languages, and drastically speed up patch triage and rollout before attacker capabilities outpace defenses. | |

tl;dr: An interactive visualization plots every building currently standing in LA County as a box, appearing in the year it was constructed, spanning 1880 to 2026. Because demolished structures are excluded, the animation depicts the surviving building stock rather than a true historical record of the county's development. | |

| 6. | Leaving VMware just got harder after Broadcom pulled VDDK downloads(virtualizationhowto.com) |
| 263 points by josephcsible 2 days ago | 149 comments | permalink | |
tl;dr: Broadcom has quietly removed public downloads for VMware's Virtual Disk Development Kit (VDDK), a library that underpins migration tools from Microsoft Azure Migrate, Red Hat MTV, Nutanix Move, Platform9's vJailbreak, and virt-v2v. Support has reportedly confirmed the removal is intentional, with access now restricted to Broadcom Technology Alliance Partners, forcing customers into agent-based migrations or storage-assisted workarounds. Proxmox migrations are unaffected since its built-in import tool doesn't rely on VDDK, but the timing—coinciding with the return of vSphere Standard—looks to many like a lock-in tactic against customers leaving the platform. | |

tl;dr: Jellyfin 12.0 drops the leading "10." from version numbers and builds on the 10.11 database rewrite with major performance gains, particularly for playlists and collections (now stored per-row rather than as monolithic blobs). Notable additions include proper native support for books/comics (absorbing much of the Bookshelf plugin), alternate versions for TV episodes, per-library recommendation sources, and the Modern layout as default. Upgrading requires being on 10.10.7 or 10.11.x first, a full backup, a mandatory library rescan, and removal of third-party plugins; legacy `/emby/` and `/mediabrowser/` endpoints are also gone. | |

tl;dr: Google's WeatherNext 3 is a global AI weather model that generates hourly forecasts directly from raw satellite imagery, predicting surface variables like temperature and humidity at 5km resolution and wind at 10km. It targets both consumer products (Search, Maps, Gemini) and industry applications such as renewable energy operators needing radiation and cloud cover data. Google claims it helped the National Hurricane Center improve predictions for Hurricane Melissa's landfall in Jamaica. | |

tl;dr: Researchers demonstrate that Thompson's trusting-trust attack isn't limited to compilers by implementing it via GNU strip, a build utility that neither reads nor emits source code. Using a single tampered strip binary in the NixOS bootstrap seed, they propagate a backdoor across strip generations that persists after the seed exits the dependency closure, ultimately backdooring nearly every binary in a full graphical installer built from a real nixpkgs revision. | |

| 279 points by exploraz 5 days ago | 79 comments | permalink | |
tl;dr: Ladybird's August update brings video playback on Twitch, JavaScript debugging in DevTools, CSS scroll snap, resumable downloads, and full session restore. Major performance work landed via a new incremental style engine, layout result caching, and off-main-thread CSS animations, roughly doubling StyleBench scores and lifting Speedometer numbers significantly. CSS parsing and the painting pipeline were rewritten in Rust, JavaScript value caging was added for security, and site compatibility fixes improved ChatGPT, VS Code, iCloud, Strava, and Outlook. First alpha is still on track for 2026. | |

| 15. | Simple Is Not Small(jyn.dev) |
| 257 points by zdw 6 days ago | 88 comments | permalink | |
tl;dr: The author argues that "simple" (decoupled) is often conflated with "small," using Unix pipelines as an example: they're small but tightly couple concerns like aggregation and ordering, making modifications painful. In contrast, large programs like Google Drive or Clojure's map-based structs can be decoupled and thus simpler to use and extend. Writing truly simple software is hard and sometimes requires massive engineering investment (see SQLite, Blink), but coupling should always be minimized regardless of program size. | |

tl;dr: Bzip3 is a modern successor to Bzip2 that combines a Burrows-Wheeler transform (via suffix arrays), LZP preprocessing, and an order-0 context mixing entropy coder to achieve significantly better compression ratios and speed. In benchmarks compressing a tar of all Perl5 releases, bzip3 outperformed xz, bzip2, and zstd on ratio (546MB vs. 2GB for xz), with decompression time competitive with zstd. It's LGPLv3-licensed and works well for text and code, though the author warns of the usual risks of relying on a newer compressor for irreplaceable data. | |

tl;dr: Caltech is hosting the first research-level math hackathon Oct 30–Nov 1, giving 100 teams 40 hours and $2M+ in AI credits to attack open conjectures using frontier models, then defend results before leading mathematicians. Prizes will be awarded on-site and again after community verification. The event is framed around recent AI-driven breakthroughs (e.g., claimed disproofs/constructions on Erdős's unit-distance conjecture, non-sofic groups, and complex structures on the six-sphere) and asks how AI reshapes mathematicians' roles. | |

tl;dr: One year into the EU's smartphone repairability rules, over 80% of devices fail to provide required repair information, with roughly half of registry entries containing blank URL fields and some pointing users to Temu or AliExpress for parts. Manufacturers self-assign repairability scores with no verification, and many non-compliant vendors still give themselves top "class A" ratings. Right to Repair Europe is calling for stricter enforcement and mandatory documentation ahead of February's incoming rules requiring user-replaceable batteries. | |

tl;dr: A software engineer noticed his thinking had grown lazier after 8 years on the job, compounded by AI tools and phone-based dopamine hits. During a slow countryside vacation, he read four books and rediscovered learning for its own sake by working through calculus, trigonometry, and physics textbooks (Stewart's Calculus, Paul's Notes, University Physics). He reports feeling less intellectually lazy, though he's unsure if the effect will last. | |
