Oil companies report sky-high profits thanks to wartime crude prices

Oil majors Chevron, Shell and ExxonMobil posted record profits as wartime crude prices and refining margins climbed. Chevron’s quarterly earnings topped its history; Shell’s were second-highest; ExxonMobil doubled its profit from a year earlier. Averaged together, they earned about $404 million per day over the last three months. The surge spurred windfall-tax talk in the U.S. and Europe (the EU already has one). Despite Middle East disruptions and attacks on Russian refineries, producers say they will use profits to pay down debt and pursue long-term growth rather than rapid new drilling.

Franken.domains: Stitched-Together Domains, Because Every .com Is Taken

franken.domains is a lab-themed project that stitches together dictionary words with donor country-code top-level domains to create new, "reanimated" domains. Real words are grafted onto donor limbs from hundreds of TLDs and then verified against the registry, producing lifeless specimens waiting to be reanimated. The page lists examples (e.g., kulturmagaz.in, ladisla.us) and notes providers for reanimation (IONOS, united-domains, World4You, etc.). Warnings about registry lifelessness, residency rules, and pricing accompany affiliate links. Created and curated by Klaus Breyer.

BMW Is Showing Commercials on Their Car's Dash Screens as a Treat

BMW has begun showing a Spider-Man: Brand New Day animation on the car’s center display as part of a brand partnership. The banner appears at start-up and can be clicked to view a full-screen animation with music and ambient lighting; the campaign runs July 27–August 10 in participating markets, in over 70 countries, for vehicles with BMW OS 7/8/8.5/9 or BMW OS X and production after 7/2020. The Autopian article condemns this as invasive in-car advertising, arguing it undermines ownership, and calls for avoiding new BMWs.

Rear center fuel tank adds roughly 20k liters and extends range by 1k NM

Airbus completed the first flight of the A350-1000ULR (MSN 707) in Toulouse, testing its extended-range with an added rear centre tank to enable non-stop Sydney–New York and London flights (~10,000 nm, up to 22 hours). The flight tested the new fuel system, cabin ventilation/air cooling, and an updated galley cooling system ahead of retrofitting to Qantas’ specs. A second ULR for Qantas is nearing final assembly and due for delivery in April 2027. The A350-1000ULR is the fourth A350 passenger variant; overall A350 family orders exceed 1,570 with Qantas as a major customer. The A350F freighter is in development.

Assessment of open AI math results

Igor Kotenkov and AI classifiers (GPT-5.6 Sol Pro and Fable 5 Max) used EpochAI/OpenMath rubrics to classify ten math results. They agree #3 is a Breakthrough; at least seven are Major Advances; they disagree on #7 (Solid vs Major). Fable marks #1, #4, #9 as Borderline Breakthrough; official rubrics favor a conservative downgrading approach. An OpenAI Astra-like internal model reportedly solved 10 major open problems, a potential major step for scientific reasoning. Sean X. Luo notes #3 could appear in an introductory algebra textbook.

Kaisel – Routes as Values. Dart 3 Native Router for Flutter

kaisel is a Dart 3-native Flutter router that treats routes as values rather than strings or codegen. It uses sealed classes and exhaustive switches so the compiler ensures all routes are handled, eliminating unknown routes. The navigation history is a List of route objects; push, pop, and set are list operations, testable without a widget tree and restorable across process death. It requires zero codegen—routes are plain Dart classes. Features include a single NavigatorObserver, support for tabs, adaptive layouts, guards, and deep linking. It also offers migration paths from go_router, auto_route, and Navigator.

Study uncovers lost 'golden age' of languages

New global study coauthored by Yale linguist Claire Bowern argues that linguistic diversity peaked 1,000–3,000 years ago, with tens of thousands of languages spoken worldwide, followed by a long decline as states and multinational empires spread their languages. While European colonialism intensified losses, it did not initiate them. Today roughly 7,600 languages remain, representing a biased remnant of an earlier, far richer diversity. Using ethnographic data, prehistoric population estimates, and modelling, the team links language diversity to demographic and political change across the Holocene.

Explorative modeling: Train on the best of K guesses

Explorative Modeling (XM) adds a third pretraining axis by exploring multiple plausible outputs during training (for loop over K generations) and training only the best match. This ‘mode forcing’ increases generative expressivity, letting models commit to diverse valid answers rather than the data average. As a result, XMs improve data, compute, and parameter efficiency, generalization, and end-to-end generation, across images, video, and language; gains scale with data and model size and can reach or exceed diffusion performance with far less inference compute. XMs can augment existing models or enable end-to-end generation; future directions include Reverse XM and gradient-based exploration.

Indexing the Data Lake for Online Point Queries

Spotify describes RAP (External Index for Parquet), an approach to fast point queries on a data lake. A dedicated index maps each key to the exact Parquet file and row, enabling O(1) lookups and a few precise, ranged reads instead of scanning. It targets petabytes in cloud storage, avoiding copies or ETL. Optimizations include concentrating key data (sorting, co-grouping, coarser partitioning), reducing bytes per read (one key per page, ZSTD frames, interleaving columns, covering index), and supporting secondary indexes. The payoff: single or few kilobyte reads, letting analytics and online workloads share the same lake.

Cursor removed cost information from the usage page and CSV export

Cursor switched the Usage page from dollar costs to token amounts for self-serve/Teams plans on 2026-07-31. There is no UI toggle to revert; enterprise plans still show dollars. Dollar values are no longer returned by the dashboard Usage endpoint for self-serve plans, and per-user/per-model breakdowns are unavailable. You can view dollars in Dashboard > Spending (On-Demand) and in Dashboard > Usage CSV (on-demand rows show costs; included usage shows “Included”). Admin API still provides cost fields for Teams. Users are requesting restoration or a toggle.
