myc: open-source local memory tool stops AI coding agents from forgetting context

·33 views

A free, MIT-licensed tool called myc (short for mycelium) has been released on GitHub to address a common frustration with AI coding agents like Claude Code and Codex, which lose agreed-upon decisions when their context window is compacted. The tool stores tasks and decision logs locally in a single SQLite file alongside the project, requiring no cloud API or API key. A PreCompact hook writes the session to disk just before compaction and reinjects a recovery packet into the surviving context, preserving earlier decisions. Memory entries are anchored to specific code segments and automatically downweighted if that code is deleted, while decisions extracted from transcripts remain unconfirmed candidates until a human approves them. Currently, myc supports only Bun runtime on macOS and Linux in single-user mode, with no team or server functionality planned yet.

U.S. Sets New Rules on Synthetic DNA Orders to Curb Bioterrorism Risks

The United States has introduced new regulations governing how companies and customers order synthetic DNA. The rules are aimed at deterring the misuse of such material for bioterrorism. Synthetic DNA can be used to build genetic sequences, which raises concerns about potential threats if obtained by malicious actors. The policy seeks to add safeguards to the ordering process without, according to the framing of the report, halting legitimate scientific research. Further details on specific requirements were not available in the provided information.

Tracking form submits and click-to-call taps to the original traffic source

Pageview analytics show that visitors arrived but not which ad, keyword, or search produced a lead, because the conversion happens in an inbox or phone log. The article argues that the fix is to store the first-touch source on a visitor's initial landing and attach it when a contact form is submitted or a tel: link is tapped. It describes four useful signals: UTM parameters, the document referrer, and the gclid and fbclid click IDs from Google and Meta ads. A simplified JavaScript example shows how to save this data locally and add it as hidden form fields or send it with a beacon. The author cautions that the sketch needs a server, consent handling, and a way to detect AI-assistant referrals, and should not be treated as a complete identity system.

Sitemap Audits Reveal Hreflang and Canonical Errors Across Five-Language Site

A developer describes auditing an 80-URL sitemap spanning five languages and finding that correct-looking configuration can still be broken. Each page needs six hreflang tags, including x-default, and every referenced URL must return a 200 status with a consistent canonical. A single stale alternate URL can cause the entire hreflang cluster to be ignored by crawlers. The author recommends generating canonical and hreflang tags from one per-page translation map and checking that breadcrumb structured data matches the visible trail. They also advise fetching deployed pages to confirm tag counts, since partial uploads can silently fail.

Developer builds Android Reddit reader using public RSS feeds, avoiding API keys

A developer wanted to read public Reddit threads without creating an account or registering for the official API, which requires OAuth and token refresh. They built a small Android client, about 105 KB with no server or analytics, that relies on Reddit's public RSS endpoints instead. The feeds return Atom XML and cap results at 25 listing posts and 100 thread entries, and Reddit rate-limits them per IP, returning HTTP 429 errors that should trigger a retry. The article also covers the feed's entry structure, which lacks comment scores or parent pointers, and shows how Android's built-in streaming XML parser can process the feed.
