Show HN: Display.dev – the agent-agnostic workspace for HTML and .md artifacts
4 hours ago
- Display.dev provides a platform to generate a permanent, shareable URL for any artifact created by AI agents (like Claude, Codex, Cursor) or any tool that writes a file.
- Artifacts are gated by default behind company SSO (Google/Microsoft login), allowing only teammates with verified company email domains to access them with one click; all others see a login wall.
- The platform preserves interactive elements (like live D3 charts) and formatting (styled HTML from Markdown) in artifacts, moving beyond static screenshots.
- It enables a collaborative workflow: teammates can comment directly on artifacts, agents can read comments via MCP, make fixes, and resolve threads, with both agent and human actions logged.
- Pricing is flat and based on storage/capabilities, not the number of viewers; it includes a free tier and paid plans (Teams: $49/mo, Pro: $499/mo) with features like audit logs and private artifacts.
- It positions itself as a cost-effective solution (7–40x cheaper for 100 viewers) compared to alternatives like Vercel, Cloudflare Pages, GitBook, or DIY setups, especially for sharing authenticated HTML artifacts.
TypeScript 7.0 RC
3 hours ago
- TypeScript 7.0 Release Candidate (RC) is announced, built on a new Go-based foundation, offering up to 10x speed improvements over TypeScript 6.0.
- It can be installed via npm: `npm install -D typescript@rc`; editor support is available through the TypeScript Native Preview extension for VS Code.
- The new Go codebase maintains architectural parity with TypeScript 6.0, ensuring identical type-checking semantics and compatibility with existing test suites.
- It supports parallelization with configurable flags like `--checkers` and `--builders`, and includes a single-threaded mode via `--singleThreaded`.
- A rebuilt `--watch` mode uses a ported Parcel file-watcher for efficient cross-platform performance, reducing resource usage.
- TypeScript 7.0 adopts TypeScript 6.0's new defaults and deprecations, including changes to `rootDir`, `types`, and strict error handling for deprecated features.
- Template literal types now preserve Unicode code points, changing inference behavior for strings with surrogate pairs.
- JavaScript support has been reworked for consistency with TypeScript analysis, removing special treatment for certain JSDoc patterns and Closure syntax.
- The release includes side-by-side compatibility with TypeScript 6.0 using the `@typescript/typescript6` package and npm aliases to avoid conflicts.
- Nightly builds are available under `@typescript/native-preview`; stable releases will be published under the `typescript` package after final release.
- Feedback is encouraged from real projects via the issue tracker or social media, with a stable release planned within the next month.
Show HN: Gerrymandle - Daily puzzle game where you redraw electoral districts
4 hours ago
- Gerrymandle gameplay involves drawing district lines by grouping adjacent tiles to form districts, each of which must be a single connected shape without islands.
- Colored houses represent voters; districts must contain all houses, with districts being equal in size.
- The goal is to draw districts so that your party wins more districts than others by having the most houses in each district, with ties meaning no win.
- Gerrymandering is defined as drawing electoral districts to favor one party, using techniques like packing opponents into few districts and cracking their remaining voters across others.
- The term originated from Governor Elbridge Gerry in 1812, with historical roots, and today uses algorithms for precise manipulation.
- Gerrymandering is harmful because it makes general elections irrelevant, shifts power to primary extremes, and ignores centrist voters, with measurable effects on election outcomes.
- It also disproportionately impacts minority communities through packing or cracking, and legal challenges have become harder due to court rulings requiring proof of discriminatory intent.
- The practice has accelerated, with over 25% of congressional seats redrawn mid-decade since 2020, turning redistricting into an ongoing political tool in states like Texas, California, Virginia, and Florida.

Next-Latent Prediction Transformers Learn Compact World Models (2025)
a day ago
- The paper introduces Next-Latent Prediction (NextLat), an auxiliary training objective for transformers that adds self-supervised predictions in the latent space.
- NextLat encourages transformers to form compact internal world models with belief states and transition dynamics, improving generalization over standard next-token prediction.
- Theoretically, NextLat's latent representations converge to belief states, which are compressed summaries of history necessary for future predictions.
- Empirically, NextLat shows gains in benchmarks like world modeling, reasoning, planning, and language modeling, enhancing accuracy, compression, and planning.
- NextLat also enables variable-length self-speculative decoding, accelerating inference by up to 3.3x in language modeling while leaving transformer architecture and efficiency unchanged.
U.S. Demands to Access Africans' Data Raise Privacy, Sovereignty Concerns

Bulgaria Licensed Surveillance Exports to Rights Violators
4 hours ago
- Bulgaria licensed surveillance equipment exports (2018-2023) to countries likely to use it for repression or human rights abuses.
- EU governments, including Bulgaria, issue licenses without proper human rights due diligence, despite existing export control laws.
- Licenses covered exports to 15 countries, including Azerbaijan, Bahrain, UAE, and Israel, for clients like intelligence and police agencies.
- The licensed technology enables interception of communications, geolocation, and mass surveillance, raising risks of misuse against activists and journalists.
- Circles, the Bulgarian surveillance firm, is linked to spyware controversies, including sanctions and a founder convicted for illegal surveillance in Greece.
- EU regulations require member states to consider human rights records when approving exports, but enforcement is weak and transparency lacking.
- Both Bulgarian authorities and the European Commission are criticized for failing to control exports effectively, allowing surveillance tools to reach repressive regimes.
ACLU: Do Automatic License Plate Readers violate privacy under the 4th Amendment
3 hours ago
- The ACLU, ACLU of Virginia, and Electronic Frontier Foundation filed an amicus brief on April 20, 2026, challenging Norfolk police's use of Flock ALPRs in the Fourth Circuit Court of Appeals.
- The brief argues ALPRs collect extensive sensitive location data, including from non-suspects, and store it in interconnected databases with inconsistent retention periods.
- Collected data can identify vehicle owners, drivers, associates, phone numbers, and criminal histories, enabling long-term, cross-jurisdictional queries by law enforcement.
- Despite Virginia's 2025 statute prohibiting out-of-state and federal data sharing, many agencies have violated this rule, though they can still access out-of-state data and share within Virginia's internal ALPR network.
- The brief concludes that ALPRs violate Fourth Amendment privacy expectations due to indiscriminate data collection and retrospective searches, urging the Fourth Circuit to reverse the district court's ruling.
How Alberta Eradicated Rats
5 hours ago
- Alberta is the largest rat-free area on Earth after Antarctica, maintaining this status for over 70 years despite sharing borders with rat-infested regions.
- Norway rats (Rattus norvegicus) invaded North America, displacing black rats, and spread westward, threatening Alberta's farms and infrastructure.
- In 1950, Alberta declared an emergency upon discovering Norway rats near its eastern border and established a Rat Control Zone to prevent establishment.
- The Rat Control Zone focused inspections on a narrow strip along the Saskatchewan border, targeting vehicles and high-risk sites like farms and grain elevators.
- Alberta implemented a 'rodent surveillance state' with public reporting systems, seasonal inspections, and Cold War-era rhetoric to foster vigilance.
- Early eradication efforts used arsenic trioxide poisoning, which caused harm to livestock and pets, but later switched to safer warfarin bait.
- Enforcement included laws requiring rat destruction, fines for non-compliance, and public cooperation, reducing sightings significantly after 1956.
- Alberta's program costs around C$500,000 annually, much less than Saskatchewan's C$1.2 million, with minimal rat damage compared to neighbors.
- Persistence is key: Alberta continues inspections, public reports, and cross-border coordination to prevent breeding populations, though rats still enter.
- Today, Alberta remains rat-free through ongoing surveillance, with few actual rats among many mistaken sightings (e.g., squirrels), and illegal pet rats are tracked and rehomed.

Wages in America Are Too Low for the 30% Rule to Work for Renters Anymore
4 hours ago
- The 30% rent rule, a decades-old personal finance guideline, advises spending no more than 30% of gross income on housing.
- This rule is increasingly outdated due to rising costs of essentials like housing, groceries, and gas outpacing income growth, making it harder to follow.
- The median asking rent in the top 50 metros is $1,686, 17.2% higher than pre-pandemic levels, questioning the rule's relevance in today's economy.
- A key flaw is that the rule uses gross income, not take-home pay; after deductions, rent can consume over 50% of actual income, causing financial strain.
- It ignores individual circumstances like debt, childcare, or insurance costs, meaning two people with identical incomes may have vastly different affordability.
- Financial experts suggest focusing on broader questions: after rent, can you cover expenses, save, and invest, rather than rigidly adhering to the 30% rule.
- Alternatives like the 50/30/20 budget method allocate 50% of take-home pay to needs (including rent), offering more flexibility and a holistic financial view.
- Many renters adapt by living with roommates, choosing smaller spaces, or relocating, with surveys showing such adjustments are seen as smart financial strategies.
- Ultimately, prioritize what you can comfortably afford on housing based on your overall financial picture to avoid strain in other areas.
