New York City’s airport system—JFK, LaGuardia, and Newark—can create delays through traffic, security lines, parking constraints, terminal congestion, and redevelopment work. The guide recommends checking Uber airport pages, traffic reports and maps, TSA security wait times, travel alerts, and security guidelines before traveling. JFK may take 30 minutes to two hours from Manhattan and has terminal-specific peak periods, six terminals, an AirTrain option, and no official vehicle waiting zone; LaGuardia has four terminals, redevelopment-related parking limits, and especially busy Monday mornings and Friday afternoons. Newark is about 30 minutes from Manhattan, serves 50 carriers, offers short-term parking but no cellphone lot, and is described as having only 68.4% of inbound flights arrive on time, with terminal-specific busy periods and a 50%-lower UberX and UberXL fare promotion.

- Published: Apr 28, 2026
- Type: Announcement

Uber announced that, beginning May 18, 2020, riders, drivers, and delivery people would be required to wear masks or face coverings on its platform as cities began reopening during the COVID-19 crisis. The policy applied in many operating countries and was paired with cancellation and reporting options for people who felt unsafe or encountered noncompliance, while discriminatory cancellations remained prohibited. Drivers and delivery people had to complete a Go Online Checklist covering face coverings, sanitation, and keeping the front seat empty, then verify mask use with a selfie; riders had to confirm precautions, sit in the back, and open windows. Uber said it had allocated $50 million for supplies, secured more than 23 million masks, and was developing safety guidance with WHO and CDC.


### [Introducing the Work Hub, a new way for drivers to find essential work](https://yomu.fyi/post/introducing-the-work-hub-a-new-way-for-drivers-to-find-essential-work.md)
- Company: [Uber](https://yomu.fyi/company/uber.md)
- Published: Apr 28, 2026
- Type: Announcement

With fewer people moving during COVID-19, drivers have fewer trips available and are earning less, prompting the introduction of Uber’s Work Hub. The hub brings together ways to find work with Uber and other companies, including one-tap access to Uber Eats delivery requests where available, signups for Uber Works shift jobs, and priority eligibility screening for Uber Freight for drivers with a Class A Commercial Driver’s License. It also connects drivers with external opportunities from companies hiring during the period, including Domino’s, Shipt, and CareGuide, alongside links to other job postings. Uber says it will continue adding partnerships and listings, and directs drivers to check the Driver app regularly for updates.

- Company: [Uber](https://yomu.fyi/company/uber.md)
- Published: Apr 28, 2026
- Type: Problem & solution

Uber built uAct to consolidate action items and approval requests generated by its many internal applications, addressing notifications that could be lost among email and follow-ups. It combines real-time fetching with scheduled offline ingestion through Apache Camel, stores requests, and merges them in received and sent views. Users can act through deep links or within uAct, where the Action Dispatcher authenticates and authorizes actions and the Audit Trail Provider records them for compliance. Its onion-architecture backend uses orchestrators, application-specific mappers, MySQL for requests and CacheFront for preferences, while parallelized paginated calls and strict timeouts support performance as integrations grow. The platform has been implemented across Uber and also provides configurable views, hiding, manager filters, observability, privacy controls, and planned Slack notifications, reporting, nudging, and additional integrations.

Public-sector agencies face fraud methods including synthetic identities, deepfake-enhanced documentation, and personalized social engineering, while legacy controls remain fragmented and difficult to scale. The fictional Services Bureau demonstrates an operating model that combines Databricks Apps, Lakebase, Unity Catalog, Delta Sharing, Agent Bricks, and AI/BI Genie in a single fraud-operations environment. Governed data lands in Delta tables; Unity Catalog applies attribute-based access control, masks PII by role, and provides lineage, while agents connect live lakehouse queries, agency policies, and external fraud signals through MCP. Analysts review evidence and recommendations, then approve, override, or escalate cases, keeping human judgment central. The described workflow turns weeks of manual investigation into a day, supports dashboards and conversational SQL, and is presented as making fraud decisions faster, more secure, transparent, and defensible.

Healthcare data teams often spend months integrating EHR systems, normalizing HL7, CCD, and X12, and routing data through intermediary storage before analytics, creating latency and maintenance burden. Databricks and Redox describe a pipeline model that combines Redox MCP Server, natural-language prompts, and Databricks Zerobus Ingest to build integrations inside Databricks and stream clinical data directly into Unity Catalog managed tables. The post says Zerobus provides subsecond latency, while the MCP Server identifies environments, suggests workflow steps, executes integration tasks, and surfaces validation signals such as logs and performance summaries. A demonstrated workflow retrieved a recent patient admission as structured data with a plain-language summary, and Redox writeback can return AI outputs to EHRs for point-of-care action. The same foundation is presented as enabling real-time use cases and Redox Agents built with Databricks Genie Spaces.


### [AI is the answer to the sales growth-without-headcount problem](https://yomu.fyi/post/ai-is-the-answer-to-the-sales-growth-without-headcount-problem.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)

- Published: Apr 28, 2026
- Type: Problem & solution

Sales leaders have treated pipeline growth as constrained by headcount, making a 30% increase appear to require 30% more people. The post presents Intercom’s use of Fin, its Customer Agent, for inbound sales as a separate pipeline source rather than merely an efficiency layer for SDRs, with its own metrics, targets, and owner. Fin engages inbound prospects instantly, qualifies and routes high-intent visitors, and keeps lower-intent prospects warm, while SDRs focus on phone qualification, relationship-building, and helping trial users realize value. Drawing on customer-service implementation, the operating model includes dedicated AI ownership and continuous optimization against meetings, pipeline, and revenue. The conclusion is that AI can raise the pipeline ceiling above current headcount capacity, although the constraint shifts to how well the Agent understands the product, customers, and demand qualification.

Genie Code is presented as a natural-language assistant for developing, orchestrating, deploying, and debugging data pipelines and jobs. It uses pipeline and job context, including code, configuration, run results, Unity Catalog metadata, lineage, popularity, and code samples, to help engineers discover datasets and understand data flows. Engineers can describe pipelines or jobs, and Genie Code can generate Spark Declarative Pipelines with Bronze, Silver, and Gold layers, sources, transformations, data quality expectations, and outputs, then configure orchestration, schedules, dependencies, Auto Loader, AutoCDC flows, and Declarative Automation Bundles. It also analyzes failures and unexpected row-count or schema changes, proposes cross-file updates with reviewable diffs, and supports extensions through custom instructions, agent skills, and MCP servers. The stated result is faster development and guided debugging while workflows remain aligned with Unity Catalog governance, performance, and data quality standards; future plans include background failure response and cluster right-sizing.

Snapchat Conversions API is now available as a Databricks Marketplace listing that lets teams activate first-party conversion signals directly from governed Lakehouse data. The included pre-built notebook reads gold-layer tables, batches web, app, and offline events, and supports deduplication with Snap Pixel, allowing server-side signals without double-counting. Because it runs in the Databricks environment, Unity Catalog preserves governance, lineage, security, and access controls while teams control what data is shared and when. The post says fuller server-side coverage can raise Event Match Quality, while citing that advertisers who improved their EQS from “Poor” to “Good” saw 26% higher ROAS and 49% lower CPI. It also describes fresher custom audiences and Lookalikes plus more complete deduplicated measurement.

Palantir’s Ontology is presented as a decision-centric architecture for human-agent operations, intended to represent how enterprises make and execute decisions rather than only storing or analyzing data. It combines data, logic, action, and security in a shared, dynamic representation that can connect operational data, computational processes, workflow execution, and policy controls. The data layer includes structured, streaming, edge, unstructured, imagery, and decision data, with decision lineage recording the data version, application, and decision context; logic binding connects heterogeneous business, modeling, planning, and optimization assets for human and agent workflows. The architecture exposes approved actions to agents with configurable human review and guardrails, while capturing decisions as learning material for improving workflows and agentic memory. It concludes that a real-time ontology can anchor AI in enterprise conditions while controlling where automation is allowed.

- Type: Announcement

Supabase has launched the OSSCAR Index, a quarterly ranking of fastest-growing open source organizations, with the site, data, and scoring code released as open source. It addresses the limits of rankings based on accumulated stars, downloads, or contributors by measuring community growth within two divisions: Emerging organizations below 1,000 GitHub stars at quarter-start and Scaling organizations at or above that threshold. Scores combine normalized net new stars, unique contributors, and npm, PyPI, and Cargo downloads using an L² norm, with minimum thresholds and no penalty for missing or declining signals. The Q1 2026 edition identifies Openclaw as a breakout project, places AI-agent projects prominently in Emerging, and reports global representation; quarterly updates, expanded package coverage, an RFC process, and historical rankings are planned.


### [Formatting an entire 25 million line codebase overnight: the rubyfmt story](https://yomu.fyi/post/formatting-an-entire-25-million-line-codebase-overnight-the-rubyfmt-st.md)
- Company: [Stripe](https://yomu.fyi/company/stripe.md)
- Author: Fable Tales
- Published: Apr 28, 2026
- Type: Problem & solution

Stripe’s 25-million-line Ruby codebase needed a true autoformatter; before rubyfmt, no industry-wide Ruby formatter existed, and earlier tools had crashed on its files. rubyfmt began as a zero-configuration open-source project motivated by formatting disputes, Ruby’s slow startup, and the uncertainty faced by engineers arriving from other languages. To meet a 100ms target, it initially used a hand-authored C launcher and later moved formatting into Rust, with ripper parse trees first passing through JSON and eventually being deserialized directly from Ruby VALUE objects. Stripe adopted per-file opt-in, expanded coverage cautiously, and formatted the codebase on a Saturday in 2024; the excerpt reports that all 42-million-line Ruby codebase is now formatted. In 2025, migrating from ripper to Prism removed the need to link a Ruby VM and made rubyfmt smaller and dramatically faster.


### [How leading tech companies are killing the builder's tax with Lakebase](https://yomu.fyi/post/how-leading-tech-companies-are-killing-the-builder-s-tax-with-lakebase.md)
- Company: [Databricks](https://yomu.fyi/company/databricks.md)
- Author: Amey Banarse, Madelyn Mullen
- Published: Apr 27, 2026
- Type: Explainer

The post argues that AI-native applications face a “builder’s tax” because operational databases and lakehouse analytics are separated by CDC, ETL/ELT, and reverse ETL pipelines. This architecture can leave AI systems with stale data while duplicating governance and shifting engineering effort toward orchestration and failure management. It presents Lakebase, a fully managed serverless Postgres engine integrated with the Databricks Data + AI Platform, as a shared operational foundation where applications, agents, analytics, and governance use the same data. The proposed pattern combines a lakehouse intelligence layer, a low-latency Lakebase execution layer, and a continuous learning loop, with pgvector supporting agent memory and semantic search. Reported customer examples include faster feature onboarding, reduced on-call disruption, higher agent throughput, and consolidated data estates, though the results vary by organization.
