1. Signal Protocol and Post-Quantum Ratchets
Total comment counts : 18
Summary
Graeme Connell and Rolfe Schmidt announce Sparse Post Quantum Ratchet (SPQR), a new post-quantum ratchet for the Signal Protocol that strengthens quantum resistance while preserving forward secrecy (FS) and post-compromise security (PCS). SPQR, used with Signal’s existing Double Ratchet as the Triple Ratchet, improves protection against harvest-now-decrypt-later attacks. For users, nothing changes and conversations will automatically transition to the updated protocol. The current protocol relies on quantum-safe hash functions for FS and ECDH-based PCS; SPQR adds a regularly advancing post-quantum mechanism to maintain FS/PCS in a quantum future, by updating keys without exposing past secrets.
Overall Comments Summary
- Main point: The thread analyzes Signal’s SPQR (Sparse Post-Quantum Ratchet) announcement, focusing on its claimed post-quantum security features and the practical tradeoffs for user privacy and protocol comparisons.
- Concern: The main worry is that even with SPQR, issues like phone-number-based identity, potential government ownership of numbers, and cloud backups with static keys could undermine forward secrecy and overall privacy.
- Perspectives: Views range from enthusiastic praise for formal verification and security improvements to skepticism about real-world impact, usability, and comparisons to iMessage, Matrix, and MLS, along with questions about funding and practicality.
- Overall sentiment: Mixed

Total comment counts : 18
Summary
Bron Gondwana, CEO of Fastmail, argues that AI is transforming products but email’s immutability preserves memory and history unlike the web. Fastmail tolerates user AI use if it complies with Terms of Service and won’t degrade service. The company emphasizes privacy-preserving use of AI, staff education, and data stewardship, grounded in its 2016 principles that data is the user’s. Fastmail will continue to build tools and integrations to enhance email, calendars, and contacts while prioritizing user control over data.
Overall Comments Summary
- Main point: The discussion centers on making media and communications in an AI-enabled world immutable and verifiable through methods like watermarking, authentication by trusted agencies, and end-to-end platform verification, while debating the practicality and implications.
- Concern: A key concern is that AI could still enable content manipulation or history rewriting, and verification systems might create new gatekeepers or fail to guarantee true immutability.
- Perspectives: Viewpoints range from strong support for verifiable, watermark-based authentication and platform badges to caution about practicality, privacy, and the limits of such systems, including skepticism about blockchain and a preference for traditional, self-hosted approaches.
- Overall sentiment: Mixed
3. I keep blogging with Emacs
Total comment counts : 11
Summary
The author envies lean static-site setups but relies on Org mode publishing, exporting to HTML via a sprawling, opaque stack (ox-html, ox-publish, ox, org-element) totaling over 20,000 lines. Despite the complexity, the Babel feature—embedding and running code during export with sessions, variable injection, and inline code highlighting—makes Org invaluable, especially for R plots. A self-made 2,000-line blog generator would be a fun challenge, but mirroring Babel’s capabilities would take months. They’ll continue using Org, and invite feedback and coffee.
Overall Comments Summary
- Main point: The thread discusses balancing automation and control in blog/website publishing, using org-mode and various static site generators as examples.
- Concern: Automation can impose limitations and obscure understanding, making it risky when changes are frequent or bespoke workflows are needed.
- Perspectives: Viewpoints range from embracing automated pipelines with powerful tools to building simpler, understandable custom generators or switching to different stacks for simplicity.
- Overall sentiment: Mixed

6. A simple habit that saves my evenings
Total comment counts : 7
Summary
The article describes the struggle of software engineers juggling meetings, Slack, and interruptions, making long uninterrupted work rare. The author recalls staying late to finish a solution, only to end exhausted with little progress. From a personal experience at KazanExpress, they learned it’s better to stop when a task won’t likely finish in 20 minutes: write down the next steps and a step-by-step plan, then go home and rest. This clears the mind, maintains work-life balance, and can spur better ideas by sleeping on it. The two main ideas: document plan and rest, return refreshed.
Overall Comments Summary
- Main point: The thread discusses using an end-of-day review and a written step-by-step action plan as a habit to finish tasks more efficiently and reset for the next day.
- Concern: In practice, toxic workplace culture, time-zone interruptions, and barriers to accessing inputs can make formal end-of-day reviews impractical or frustrating.
- Perspectives: Opinions range from enthusiastic support for the habit as a way to avoid ruts and improve momentum, to reports of real-world obstacles and skepticism about the proposed solution, with some valuing the idea of stopping on time but others finding it difficult to implement.
- Overall sentiment: Mixed
7. Why I chose Lua for this blog
Total comment counts : 12
Summary
The author moved from a Racket/Pollen stack that caused editing-friction to a simpler setup. They considered Grav but preferred a lightweight solution. They critique JavaScript for rapid, breaking changes and maintenance burdens, and note a friend’s Ruby stack that’s hard to sustain. They chose Lua for its slow evolution and easy bootstrap, building an old-school CGI-bin app with Lua, SQLite, and Mustache—one process per request. It’s lightweight, handles modest traffic (about 50k weekly), and prioritizes stability and long-term viability over cutting-edge tooling.
Overall Comments Summary
- Main point: People are reminiscing about learning by building a personal blogging engine and are debating lightweight, self-hosted tooling across Lua, Perl, Python, and related ecosystems.
- Concern: The main worry is that modern web stacks and ecosystems may make such projects unnecessarily complex or fragile, threatening long-term simplicity and maintainability.
- Perspectives: The thread presents a mix of nostalgia for DIY approaches, advocacy for small, stable libraries and languages (Lua, Perl, Python), critique of Lua or JS ergonomics, and practical ideas using tools like Caddy, OpenResty, markdown pipelines, and single-file frameworks.
- Overall sentiment: Mixed.
8. Why most product planning is bad and what to do about it
Total comment counts : 7
Summary
Railway abandoned OKRs for causing ceremony without clarity and adopted Problem Driven Development (PDD): a four-day quarterly process that identifies real problems, prioritizes as a team, and commits publicly. This approach kept shipping velocity as they scaled to 1.7M+ users. OKRs work when goals are concrete and measurable, like binary product existence, but falter with unlimited objectives and when engineering creativity is needed. The company isn’t anti-planning; they’re anti-bad-planning. PDD aims to align the organization around solvable problems and deliver continuous value, a pattern others can adopt.
Overall Comments Summary
- Main point: The discussion questions the value of quarterly planning as a ritual and argues for problem-driven, value-focused alternatives (e.g., Weighted Shortest Job First) rather than committing ahead to a plan before solving the problem.
- Concern: The main worry is that planning becomes a political, rigid exercise that commits capacity and headcount before understanding the problem, leading to wasted work and misalignment with product maturity or market fit.
- Perspectives: Views range from defending or accommodating quarterly planning (and SAFe-style cadence) to strongly criticizing it in favor of time-boxed, reality-tested, problem-focused approaches that emphasize value and cost.
- Overall sentiment: Mixed, with substantial skepticism toward traditional planning and openness to problem-centered alternatives.
9. We bought the whole GPU, so we’re damn well going to use the whole GPU
Total comment counts : 12
Summary
Researchers released a throughput-optimized megakernel for tensor-parallel Llama-70B inference on H100 GPUs, integrated into the Tokasaurus engine. The approach fuses a large portion of the forward pass into a single pipelined instruction interpreter per SM to aggressively overlap compute, memory, and cross-GPU communication, leveraging tensor cores, HBM bandwidth, and NVLink. For large-batch sequence-parallel tensor-parallel workloads, it achieves higher hardware utilization than traditional kernels and outperforms SGLang by over 22% in end-to-end throughput on 65,536 prompts (ShareGPT). The code is experimental and not officially supported.
Overall Comments Summary
- Main point: The discussion weighs how to exploit modern NVIDIA GPUs more efficiently (through features like NVDEC/NVJPG, multi-instance GPU, and heterogeneous cores) via smarter compilers and sharing models, versus the practical realities of software tooling and deployment.
- Concern: The main worry is that hardware advances may outpace software ecosystems, drivers, and workload management, risking underutilization or instability.
- Perspectives: Opinions range from optimism about extracting efficiencies and GPU sharing to skepticism about applying these ideas to consumer GPUs and critiques about clarity and practicality.
- Overall sentiment: Mixed
10. RISC-V Conditional Moves
Total comment counts : 3
Summary
The article extols aarch64’s csel as a single instruction that selects between rs1 and f(rs2) based on a condition, and shows how f0..f3 can create booleans, masks, or abs, enabling various conditional-logic patterns. It notes RISC-V lacks a direct equivalent to csel; only some conditional-logic conversions exist (e.g., slt), with Zbb adding min/max and Zicond adding czero.eqz/nez. The general case was considered and rejected in the ISA manual, which argues against branchless conditional moves. While some SiFive cores fuse short branches into conditional moves, memory-model details mean such fusion can be non-equivalent and must preserve branch-like properties.
Overall Comments Summary
- Main point: The discussion critiques RISC‑V instruction fusion (as used by SiFive) and questions its practicality, correctness, and potential for standardization.
- Concern: There is worry that fusion could violate memory consistency guarantees, be applicable only to a narrow set of instructions, and thus offer limited portability or real benefit.
- Perspectives: Some view fusion as a legitimate, documen table optimization pattern worth standardizing, while others warn it may be unsafe or impractical due to memory-model nuances and limited applicability.
- Overall sentiment: Mixed
