MapWit: A Chrome Extension That Turns Google Maps Searches Into Scored Sales Leads

·2 views

MapWit is a Chrome side panel built for people who sell to local businesses, such as web studios and freelancers. It reads Google Maps search results, collects each listing's website, phone, address and recent reviews, and assigns every lead a score from 1 to 10. The developers describe a long, uneven path to publication: the first version sat untouched for four months, lacked tests and failed on Google's Indian domain before a one-day review passed on the first round. Early testing exposed a bug that treated a listing's own Maps link as a business website, costing affected leads 5 points, and a URL-parsing flaw that let a private-address check be bypassed. The team grew from zero to 171 tests and removed features a reviewer might object to, including outreach drafting. The product runs entirely in the browser with no server or account, and exports to Excel via SheetJS.

Ubicloud and Blacksmith compared on GitHub Actions runner pricing and features

Ubicloud advertises the lowest published Linux rate for a 2 vCPU runner at $0.00125 per minute, though new accounts default to a $0.002 premium tier. The company runs an open-source cloud on bare metal in Germany, licensed under AGPL v3, and offers no Windows or macOS runners. Blacksmith sells managed runners on its own bare metal in four regions, with 3,000 free minutes monthly and support for Linux, Windows and macOS. The comparison draws on pricing and documentation published by each vendor as of 21 September 2026, with unpublished figures marked as such.

Python checker verifies that each startup-shutdown tracker row links to a live, on-topic source

A developer built a standard-library Python script to audit a tracker of Indian startup shutdowns in 2026, since broken or irrelevant source links can undermine the list. The script fetches each cited URL and flags HTTP errors, connection failures, and pages that do not mention the company. The article illustrates the problem with a YourStory link for AI fashion startup Alle that returned 403 behind Cloudflare, so its facts were sourced from other outlets instead. The tracker's reason column preserves each source's own wording, such as Zupee being described as 'on the verge' of shutdown rather than closed. The post includes sample rows for Alle, Satvacart and Zupee and the full checker code, which writes results to a report CSV.

ChatGPT Wallet Launches With Per-Purchase Approval for Agent Checkouts

OpenAI released ChatGPT Wallet on November 13, 2026, letting an agent inside dots complete checkouts after the user approves each transaction with Face ID or fingerprint. Payments use network-issued tokens from American Express, Mastercard, or Visa, so neither the agent nor the merchant sees the actual card number. Early access is limited to US residents aged 18 and over with eligible US-issued cards and a ChatGPT Pro subscription, and pre-approved purchases under spending limits are planned for later. The accompanying developer guidance urges merchants to publish accurate prices, availability, and terms in crawlable form and to accept signed agent requests rather than block them. The article also notes that United has barred AI agents from booking or servicing its tickets without asking first.

Agent Approval Should Hinge on Action Consequences, Not Model Confidence

A DEV Community article argues that approval systems for AI agents often ask whether an action is safe rather than what happens if it is wrong and whether it can be undone. It uses a hypothetical procurement agent to illustrate how routing every payment to a human can produce rubber-stamp approvals and late reviews after key decisions are already made. The author proposes setting review thresholds by consequence and reversibility, reserving human approval for actions that send data externally, change permissions or financial details, create external commitments, or rely on ambiguous instructions. Approval requests should specify the proposed action, its scope, the authority used, and the resulting effects. The piece concludes that confidence scores can help prioritize review but should not determine whether it is required.
