first_img The developer who replicated Photoshop is taking action again, releasing an open-source clone of the Microsoft Office suite

Brandon Thomas, the developer who previously used AI to reconstruct Adobe Creative Cloud for free, has now turned his attention to Microsoft Office. He has released open-source clone applications WordCraft, GridCraft, and DeckCraft on GitHub, corresponding to Word, Excel, and PowerPoint, respectively. The three applications are written in Rust, with a single codebase that can run natively on Windows, macOS, Linux, and BSD, and can also run in a browser. Thomas refers to this as a clean room reconstruction, meaning it is based on publicly available file format specifications and observations of the original software's behavior, without ever copying Microsoft's code, similar to the legal path taken by Compaq in the 1980s to clone the IBM PC BIOS.WordCraft can read and write .docx format, covering 88% of the features in the Word ribbon. It currently supports revision tracking, footnotes, citations, and mail merge; however, taking into account document fidelity and stability, the team estimates its completeness as a Word alternative for actual work is only about 60%, and it is still labeled as an alpha early testing version. GridCraft has supported 513 out of 523 Excel worksheet functions and 89% of ribbon commands, with the developer self-assessing about 50% as usable for actual work. The next step is to improve compatibility with real .xlsx files.

first_img NEXTPredict invested $12,000 to hedge against flight cancellation risks at Kalshi

The media and conference organization NEXTPredict announced that it has executed the first trade in the flight cancellation market through Kalshi to hedge investments for its October summit, locking in $3 million in guarantees. The company paid a premium of $12,000, and if the cancellation rate of flights arriving at New York's Kennedy International Airport on October 21 exceeds 50%, the contract will automatically pay out, covering the summit costs, as October 21 is the main travel day for attendees. Susquehanna acted as the market maker for this transaction.Kalshi launched the flight cancellation market after self-certifying the contract with the U.S. Commodity Futures Trading Commission (CFTC) on July 14, allowing participants to trade on whether the cancellation volume at specific airports exceeds preset thresholds. This market does not target individual flights and has clear anti-manipulation clauses. NEXTPredict is a media and event platform focused on the global prediction market industry, launched by the NEXT.io team. Its flagship event, the "Global Prediction Market Summit," will be held from October 22 to 23, 2026, at Convene Hudson Yards in New York, bringing together founders, executives, investors, and policymakers.NEXTPredict and Kalshi position this trade as institutional hedging, similar to how airlines hedge against fuel costs or farmers hedge against crop yields, rather than betting on the fate of the summit.
