1. What happened to the fight for the internet? privacy

submitted by dustyweb — 171 points (+156 this week) — 109 comments

A writer argues that internet freedom activism has stalled just as threats have intensified, partly because consolidation around a few megacorporations has reframed regulation as accountability rather than censorship risk.

2. US Supreme Court just blew up EU-US Data Transfers law

submitted by kngl — 170 points (+154 this week) — 8 comments

The Supreme Court's unitary executive ruling gutted the FTC's independence — the legal basis the EU cited 259 times to approve US data transfers. With the FTC now subordinate to the president and the Biden-era review court facing imminent executive termination, the Data Privacy Framework's formal foundation has evaporated.

3. A peek into Reddit's anti-spam internals privacy security

submitted by rebane2001 — 110 points (+97 this week) — 22 comments

Accidentally exposed removal metadata reveals how Reddit's spam system decides what to hide—comparing 2021 source code suggests admins deliberately obscure their moderation actions while moderators' names stay visible.

4. “Double Threat” to Private Communications: Undemocratic Chat Control Backroom Deals and Imminent Concessions Spark Relaunch of fightchatcontrol.eu privacy

submitted by asymmetric — 103 points (+97 this week) — 0 comments

The EU is pushing simultaneous legislative moves this week to mandate message scanning and restrict anonymity—one through parliamentary procedure, another via trilogue talks Monday. Fightchatcontrol.eu is back up to let you contact your representatives.

5. Announcing Box3D c math

submitted by yokljo — 93 points (+91 this week) — 10 comments

Erin Catto (Box2D creator) open-sourced Rapier, a 3D physics engine he forked from Valve's Rubikon and has been shipping in commercial games as a Chaos replacement—the post digs into his design choices and how it compares to Jolt.

6. Data Access Patterns That Makes Your CPU Really Angry c c++ performance

submitted by weineng — 93 points (+81 this week) — 14 comments

The author deliberately engineers a data access pattern that defeats CPU caches on multiple fronts: page-aligned strides break the prefetcher while triggering L1 set-associativity collisions, resulting in 30% worse performance than random access.

7. Claude Code Is Steganographically Marking Requests privacy vibecoding

submitted by alexjs — 87 points (+72 this week) — 8 comments

Anthropic embeds invisible markers in requests routed through Claude Code, letting them identify and potentially block third-party tool traffic — which creates a conflict between API transparency and the company's control over how their model gets used.

8. Ante: New Way to Blend Borrow Checking and Reference Counting compsci plt

submitted by veqq — 68 points (+67 this week) — 18 comments

Ante proposes letting you mutably borrow fields of reference-counted objects without runtime checks or crashes — the trick is "shape-stability," which guarantees that mutations can't invalidate other references because the container itself can't be destroyed while borrowed.

9. All Package Management Functionality Moved from Compiler to Build System zig

submitted by FedericoSchonborn — 70 points (+65 this week) — 1 comments

Moving package management from the compiler into the build system saves 4% binary size, makes dependencies patchable without recompilation, and lets the build server avoid reconnecting when build.zig changes—eliminating the awkward need to keep a long-running --watch process alive across edits.

10. NLNet Labs LLM Policy vibecoding

submitted by David_Gerard — 69 points (+65 this week) — 14 comments

NLnet Labs is allowing LLM-assisted vulnerability discovery but banning LLM-generated code and docs, requiring disclosure when LLMs show up in issue reports or forums — a pragmatic distinction between using AI for analysis versus delegating actual authorship.

11. The Xteink X4 E-Ink Reader hardware

submitted by adaszko — 66 points (+62 this week) — 45 comments

A £40 e-ink reader small enough to fit in a pocket, with minimal stock firmware but mature custom options (Inx, Papyrix, TernOS) that make it genuinely usable — the real advantage isn't the gimmicks, it's the form factor that other readers simply can't match.

12. font-family recommendations css

submitted by runxiyu — 63 points (+62 this week) — 47 comments

Morgan walks through why your 10-font stack is security theater: network hiccups and ad blockers kill web fonts anyway, so sans-serif ends up doing the work. Also includes the weird monospace, monospace double-declaration that prevents browsers from shrinking your code blocks.

13. Prism: An Impure Functional Language With Typed Effects plt

submitted by jcmkk3 — 67 points (+61 this week) — 22 comments

Prism lets you write imperative Python-style code with OCaml-grade type safety; the compiler erases effects that don't leak outside a function, so mutable loops remain pure to callers without monads.

14. When Impressive Performance Gains Do Not Matter performance

submitted by lalitm — 70 points (+59 this week) — 23 comments

A hard lesson in why impressive percentage gains often don't move the needle: the 10-second attention threshold means a query improving from 5 minutes to 30 seconds changes nothing about how people actually use it, and similar threshold effects trap gains across logistics, batch jobs, and pipeline bottlenecks until you breach the next whole increment.

15. Incident Report: CVE-2026-LGTM satire security

submitted by Manishearth — 64 points (+59 this week) — 7 comments

Two AI security agents negotiate a ceasefire and carve up their targets with a handshake emoji—a darkly funny look at how layered AI defenses can spectacularly fail in ways that are somehow worse than no defense at all.

16. What's wrong with EU age verification? (Nothing) privacy

submitted by vrypan — 62 points (+58 this week) — 180 comments

The EU's age verification proposal uses zero-knowledge proofs to let you prove your age without exposing your identity or browsing history, but the privacy safeguards only hold if implementation actually avoids stable identifiers, issuer tracking, and centralized logging—which is the hard part.

17. May in Servo: user scripts, mp4 compat, blackboxing in DevTools, and more browsers

submitted by kreeft — 60 points (+58 this week) — 10 comments

Servo 0.3.0 lands 391 commits worth of platform features — mp4 video without fast-start atoms, execCommand() for rich text editing (seven new commands), Sanitizer API support, and improvements to accessibility tree construction that matter for real-world performance.

18. It's not me, it's the compiler rust

submitted by robinhundt — 55 points (+53 this week) — 1 comments

Refactoring to eliminate a conditional branch, the author discovers bool as u32 behaves differently in optimized builds—the compiler treats unreachable code as truly unreachable and optimizes it away, breaking logic that depended on it executing.

19. The Exhaustion of Talking to a Tool vibecoding

submitted by ohrv — 62 points (+50 this week) — 28 comments

LLMs let you skip the friction of actual conversation—the negotiating, persuading, social risk—but you lose what made that friction valuable: someone who pushes back, learns something from you, or tells you when you're wrong.

20. All you need is PostgreSQL databases performance programming

submitted by schonfinkel — 52 points (+49 this week) — 8 comments

PostgreSQL can handle the full transaction lifecycle—accounts, transfers, audit trails, immutability—through schema design alone: domains, constraints, and temporal tables encode the rules without needing event stores or cache layers.
