In your experience, what are sound conventions for e-ink UI development?
TL;DR I'm looking for advice regarding browser-based frontend development from people with practical e-ink UI experience. My specific device is a Bigme Hibreak Pro BW but I'm aiming for relatively broad compatibility.I've recently switched to a black-and-white e-ink smartphone with the motivation of withdrawing from the attention economy somewhat and it's a genuinely cool piece of hardware. While the majority of my needs are met by this device there are a few things I'd like to have which don't work terribly well with the e-ink screen. I'm planning to implement a couple of projects to fill these gaps, at the moment I'm planning a Lemmy frontend and an OpenRouter frontend specifically for e-ink. Both are to be browser-based rather than native, to maximise compatibility and because I'm much more familiar with the web than Android development.I would like to study the principles of sound e-ink UI design before approaching these projects to avoid creating unusable slop, in particular I am not entirely sure how to approach treating the refreshes as a first-class aspect of the design when I can't control them from the browser, and how to apply comprehensible UI conventions when a greyscale, high-contrast display is the target.Some specific problems I have out of the gate are:* Streaming LLM output to the screen is basically the worst-case scenario for e-ink, I need to buffer it and paint it in chunks without this becoming horrible to use.* Ghosting is a serious problem, browsing HN on the device is a particularly obvious example. Ideally I want to avoid scrolling as far as possible and rely on pagination instead, which I feel has the potential to become annoying if not done well.* Given I must rely exclusively on layout and type to carry the UI, what design languages emphasise these qualities best? My gut says the early Mac OS versions wouldn't be a bad place to start, this seems relevant given the display constraints

The pain
The gap
Build angle
Strengths
- Founder has the hardware and genuine use case, not theoretical
- Technical problem is well-defined with specific constraints (no refresh control, monochrome, ghosting)
- Early Mac OS and typography-first design are legitimate reference points with proven usability
- E-ink device market is growing (Bigme, Onyx expanding); timing isn't terrible
- Browser-based approach maximizes reach across device ecosystems
Risks
- Market size is tiny: maybe 50k-200k e-ink device owners globally, and only a fraction want web frontends
- This reads as a technical article/guide, not a business. The person may be seeking knowledge, not building a company
- No evidence others have this problem at sufficient intensity. One person's friction ≠ market demand
- Lemmy and OpenRouter already have working interfaces; the gap is e-ink optimization, not core functionality
- Monetization is unclear. Who pays? Device owners? Lemmy/OpenRouter? Unlikely at this scale
- High technical debt: e-ink UI patterns will need constant iteration as devices improve and APIs change
- Competing against free, open-source solutions built by hobbyists with the same constraints

Semble – Code search for agents that uses 98% fewer tokens than grep
Hey HN! We (Stephan and Thomas) recently open-sourced Semble. We kept running into the same problem while using Claude Code on large codebases: when the agent can't find something directly, it falls back to grep, reading full files or launching subagents. This uses a lot of tokens, and often still misses the relevant code. There are existing tools for this, but they were either too slow to index on demand, needed API keys, or had poor retrieval quality.Semble is our solution for this. It combines static Model2Vec embeddings (using our latest static model: potion-code-16M) with BM25, fused via RRF and reranked with code-aware signals. Everything runs on CPU since there's no transformers involved. On our benchmark of ~1250 query/document pairs across 63 repos and 19 languages, it uses 98% fewer tokens than grep+read and reaches 99% of the retrieval quality of a 137M-parameter code-trained transformer, while being ~200x faster.Main features:- Token-efficient: 98% fewer tokens than grep+read- Fast: ~250ms to index a typical repo on our benchmark, ~1.5ms per query on CPU (very large repos may take longer)- Accurate: 0.854 NDCG@10, 99% of the best transformer setup we tested- MCP server: drop-in for Claude Code, Cursor, Codex, OpenCode- Zero config: no API keys, no GPU, no external servicesInstall in Claude Code with: claude mcp add semble -s user -- uvx --from "semble[mcp]" sembleOr check our README for other installation instructions, benchmarks, and methodology:Semble: https://github.com/MinishLab/sembleBenchmarks: https://github.com/MinishLab/semble/tree/main/benchmarksModel: https://huggingface.co/minishlab/potion-code-16MLet us know if you have any feedback or questions!

Postgres extension for BM25 relevance-ranked full-text search
Last summer we faced a conundrum at my company, Tiger Data, a Postgres cloud vendor whose main business is in timeseries data. We were trying to grow our business towards emerging AI-centric workloads and wanted to provide a state-of-the-art hybrid search stack in Postgres. We'd already built pgvectorscale in house with the goal of scaling semantic search beyond pgvector's main memory limitations. We just needed a scalable ranked keyword search solution too.The problem: core Postgres doesn't provide this; the leading Postgres BM25 extension, ParadeDB, is guarded behind AGPL; developing our own extension appeared daunting. We'd need a small team of sharp engineers and 6-12 months, I figured. And we'd probably still fall short of the performance of a mature system like Parade/Tantivy.Or would we? I'd be experimenting long enough with AI-boosted development at that point to realize that with the latest tools (Claude Code + Opus) and an experienced hand (I've been working in database systems internals for 25 years now), the old time estimates pretty much go out the window.I told our CTO I thought I could solo the project in one quarter. This raised some eyebrows.It did take a little more time than that (two quarters), and we got some real help from the community (amazing!) after open-sourcing the pre-release. But I'm thrilled/exhausted today to share that pg_textsearch v1.0 is freely available via open source (Postgres license), on Tiger Data cloud, and hopefully soon, a hyperscalar near you:https://github.com/timescale/pg_textsearchIn the blog post accompanying the release, I overview the architecture and present benchmark results using MS-MARCO. To my surprise, we were not only able to meet Parade/Tantivy's query performance, but exceed it substantially, measuring a 4.7x advantage on query throughput at scale:https://www.tigerdata.com/blog/pg-textsearch-bm25-fu

Consus (YC F24) – LLM gateway for companies handling sensitive data
Hey Hacker News! I'm Eric, the founder of Consus. We route all AI requests to ITAR restricted and controlled unclassified information (CUI) compliant infrastructure. Consus itself satisfies ITAR restrictions, and we recently completed our FedRAMP equivalency audit against the 410 FedRAMP High controls. FedRAMP High is the U.S. government’s strictest security baseline for cloud services handling sensitive unclassified data. A breach of this data could cause severe or catastrophic harm. Achieving FedRAMP equivalency, or authorization, is required before processing CUI information.Demo: https://youtu.be/6MYxJe6P4oYAerospace and defense is experiencing rapid growth. Unfortunately, most companies are struggling to use AI because of necessary data protections & compliance risk. These companies can move even faster if they could use the AI tools that most other industries take for granted.I spent most of my career prior to Consus in aerospace & defense. I launched national security payloads at SpaceX, and was an early employee at Castelion. I’ve watched first hand how compliance red-tape makes it difficult for companies to adopt new technologies and trust vendors that touch their sensitive data. For example, I worked with a satellite manufacturer that doesn’t allow any AI tools, even for non-sensitive work.Even as AI has become extremely useful over the past 9-12 months, I was surprised by how many aerospace & defense companies refused to touch it. They could see how it could be helpful, but they were scared about model providers training on their data, violating an ITAR rule, or risk losing new business because of a failed cyber assessment. These are all rational fears.There were a lot of ways to solve some/all of these problems, but we focused on building a compliant AI inference layer that can "plug" into any AI tool or workflow. Just as OpenRouter integrates with most tools, Consus can connect to tools like ChatGPT or Clau
