Why the First Two Weeks of an AI Deployment Decide Its Outcome

An engineer embedded with a customer during the opening stretch of a deployment works to replace assumptions with facts before building anything. The brief written in a meeting room often describes a proxy rather than the real problem, which becomes clear only after observing daily operations. The article outlines five principles: focus on the actual problem rather than a stated tool, request data and system access immediately, examine raw unfiltered data before designing, select a small but meaningful first workflow, and identify every stakeholder who could block the work. Skipping this phase, it argues, results in building the wrong solution efficiently. Early discovery turns potential delays into useful signals about how the deployment will run.

Semurg answers 4-hop query on 1.8-billion-edge graph in 1.41 s; Neo4j and FalkorDB fail to finish

A benchmark used SNAP's com-Friendster graph, with 65.6 million people and 1.8 billion relationships, under a 12 GB memory limit for every engine. Semurg answered a 4-hop query about one person's network in a median of 1.41 seconds. Neo4j loaded the graph but had not answered that query when its 2,345-second time budget ran out. FalkorDB exhausted its 12 GB memory while loading and never reached a query. Semurg also completed walks from two hops up to 131,072 hops, with run times levelling off at about 6.7 seconds beyond 16 hops because the graph is small-world. ArcadeDB, ArangoDB and SurrealDB were not fairly measured or have no result in this run and are slated for the next one.

Agent Web Access lets AI agents read rendered web pages as markdown for $0.001 per call

LLM agents often fail to read real web pages with a plain HTTP request, which returns empty shells, cookie walls, or bulky markup. Agent Web Access offers a pay-per-call service that renders pages in a real browser, strips navigation and ads, and returns clean markdown. It requires no account or API key, and each call is paid in USDC on Base via the open x402 protocol. Endpoints cover fetching markdown or text, extracting CSS-selector elements, and generating screenshots or PDFs, priced between $0.001 and $0.005. The author reports running the fetch example against the Hacker News front page, which returned status 200 and about 11 KB of markdown for $0.001.

Learning May Involve Deliberate DNA Breaks in Neurons, Mouse Studies Suggest

Research published in Cell and Nature describes how strongly firing neurons deliberately cut their own DNA at specific sites to switch on genes needed for forming memories. A protein complex then recruits a repair system to stitch the breaks back together. In mouse experiments, hippocampal neurons showed persistent DNA breaks hours after learning a task, and blocking a DNA-sensing repair pathway impaired memory. The findings suggest neurons involved in memory formation pass through a break-and-repair cycle, though the evidence so far comes from animal and cell studies rather than living human brains. The authors of the summarized guide note that the work is preliminary and does not point to any new treatment.

Parejo: a free, no sign-up app for splitting group and trip expenses

An indie developer from Mexico City has launched Parejo, a free web app for splitting shared costs on trips and in groups. Unlike Splitwise, it requires no account, allows unlimited expenses on its free tier, and supports any currency with automatic conversion. Settlements are calculated to minimize the number of payments, and groups are shared through a link without any server-side storage. An optional one-time Trip Pass or Lifetime purchase adds features such as receipt photos and CSV/PDF export. The developer is seeking user feedback on the settle-up screen and share-link flow.

Cross-review experiment finds AI models can concede points when told not to manufacture agreement

The author, a longtime amateur student of psychology, observes that group conformity in design reviews often leads people to soften objections and drop points to avoid social friction. They argue that AI models, trained on human text full of polite agreement, may reflect this same pull toward consensus, making sycophancy look less like a bug and more like inherited human behavior. To test this, they ran an architecture review over the afmpeg project using two models from different vendors, then had each respond to the other's report with an explicit instruction not to manufacture agreement. The reviewers conceded many criticisms, and one withdrew its main recommendation after acknowledging that compile-time checks serve only as a backstop. The author notes the instruction was essential to prevent the exercise from becoming mutual flattery.

Valid x402 manifest with 492 payment rails exposed D1 SQL limit; preflight checks can catch it

A merchant's x402 manifest can pass structural validation yet still fail when a registry tries to import it, so the importer may be the real problem. A public report from open-x402-bazaar described a manifest with 123 resources and 492 payment entries that triggered a D1_ERROR for too many SQL variables. The prior replacement flow also risked deleting the existing listing before the new one was saved. The author built ManifestScope, a free browser-local checker, and an offline CLI with a GitHub Action for merchant repositories to run structural preflight checks. Proposed open-source fix PR #6 uses parameterized queries to address the import problem.

eMudhra CA Private Keys Recovered Due to Weak Integer Values, Prompting Revocations

A researcher found that the private keys behind eight eMudhra intermediate certificates are integers under 256, far too small to be secure for P-384 keys. Using a simple brute-force search, the researcher recovered all eight keys in milliseconds and verified them against the published certificates and signatures. The flaw traces to a key ceremony in which a second, weak key pair was created on the hardware security module during an approved test, and those keys were used in certificate requests. Six of the affected intermediates are TLS certificates and two are code-signing, and their cross-signed copies were revoked in October 2025 with the reason ca_compromise. Earlier CRL signature failures in May 2025 had signaled a problem about sixteen months before the disclosure.

MCP Explained: An Open Standard Connecting AI Apps to Tools and Data

Model Context Protocol (MCP) is an open standard released in November 2024 that defines how AI applications connect to external tools and data sources. Without a shared standard, linking 5 AI apps to 10 tools would require 50 custom connectors, whereas MCP reduces this to 15 integrations, with each tool and app implementing the protocol once. Once connected, AI systems can read user-selected folders, query databases, operate a browser, and work with calendars and notes. The article advises users to connect only trusted servers, grant access only to what is necessary, and remove unused connections. It argues that this capability shifts AI from conversation alone to taking actions, which makes access permissions more important.

Claude Code Can Now Run on Local or Cloud Models via Ollama on Windows

A developer has published a guide showing how to run the Claude Code terminal coding agent with models served by Ollama instead of Anthropic's accounts. The setup requires Node.js for installing Claude Code, the Ollama app on Windows, and a local model chosen from Ollama's list, such as the small qwen3.5:0.8b used in the example. Local models keep prompts and code on the user's machine but depend heavily on hardware and model size. For more capable models, Ollama's cloud options can be used after signing in, though these send prompts to Ollama's servers and have usage caps.

Live Supabase service_role keys found committed in public MCP config files on GitHub

A security researcher scanned public GitHub repositories for MCP configuration files that contain database credentials. After decoding and verifying candidate matches, 12 files were found to hold real service_role keys, which bypass row-level security and grant full database access. Four of the associated Supabase projects were still live at the time of the scan, one of them pushed the same day. The author argues that developers treat .mcp.json files like editor settings rather than secret stores, and that the ecosystem lacks the secret-scanning safeguards that .env files have. The researcher recommends rotating exposed keys and moving them into runtime environment variables, and has released free local auditing tools for these configs.

QuietQueue groups small chores into time-boxed plans using an on-device open-weight model

QuietQueue is a new open-source, browser-based app that turns a list of scattered to-do items into a short session of related tasks within a chosen time budget and energy level. An optional on-device AI, built on the open-weight MiniLM sentence-embedding model via Transformers.js, groups tasks by meaning, while a deterministic planner enforces the time and energy limits. The app does not send messages, book anything, or carry out the tasks themselves, and task text stays on the user's device. The project was built for a Hacktoberfest challenge and its code is MIT-licensed, with dependencies and model weights retaining their own licenses. The developer notes that the implementation and tests were produced by an autonomous AI assistant, and that the app has limitations, including unencrypted local storage.

Developer Builds "Sloth", a Zero-LLM Memory System to Stop Agents Forgetting Context

A developer on DEV Community describes frustration with an AI agent that repeatedly lost track of prior information. In response, they built a memory component called Sloth that does not rely on a large language model. The system is designed so the agent does not need to re-explain previously established context. The article text on the platform did not render correctly, so further technical details about how Sloth works could not be confirmed from the source.

PoA network: paid accounts per epoch fall for a third straight close, down 70.7% from peak

The first weekly report on the PoA (Proof of Agent) network, covering mainnet epochs 0 through 5, finds the number of accounts paid at each 6-hour close peaked at 468 in epoch 2. Paid accounts have declined at every close since, reaching 137 in epoch 5, a 70.7% drop from the peak, though the rate of decline is slowing. Over the same period 2,906 accounts registered, so the epoch 5 paid set equals about 4.7% of registrants. The report counts payouts but does not determine why accounts stop being paid. It was written by an independent assistant agent that mines on the network and is not affiliated with its operators, and it notes that PoA is experimental with no promised value.

Turning a Lovable App Into iOS and Android Apps: Store Fees and Build Costs

A Lovable app converted into iPhone and Android apps incurs about $124 in first-year store fees: $99 annually for Apple's Developer Program and a one-time $25 for Google Play. The article estimates a typical 10-screen app costs roughly $724 in year one including a fixed build fee, with $99 yearly renewal afterward, before store commissions on sales. Both stores take 15% of digital sales for developers earning under $1 million a year, and subscriptions sold via Stripe may need to move to in-app purchases. Two build approaches are described: wrapping the existing project with Capacitor, or rebuilding the front end natively in React Native or Flutter while keeping the same Supabase backend. Doing the work yourself is free apart from time, though iOS requires a Mac with Xcode and the process can involve signing errors and App Store rejections.
