The Codex app is now on Windows

By OpenAI

OpenAI's Codex app now runs natively on Windows using PowerShell in a dedicated sandbox, with WSL support for Linux developers. The app centralizes multiple projects with skills, automations, and work trees—plus Windows-specific features like Win UI skills. This bridges the gap for Windows developers who've been waiting for native AI coding assistance.

• Codex app runs entirely native on Windows using PowerShell inside a dedicated Windows sandbox environment
• New Windows-specific skills available including dedicated Win UI skill for Windows app developers
• WSL integration allows developers to switch coding agent and terminal to work inside Windows Subsystem for Linux
• Work trees feature enables working on multiple independent tasks within the same project simultaneously
• Available through Microsoft Store or direct download, accessible with existing ChatGPT subscription or API key

Anthropic vs The Pentagon: Who Wins? | OpenAI's $110BN Mega Round | Cursor Hits $2BN in ARR

By 20VC

Anthropic walked away from a $200M Pentagon deal over AI safety principles while OpenAI swept in with a replacement contract. Company unity around AI safety beliefs kept all seven Anthropic founders together while OpenAI lost most of theirs. This shows how core organizing principles can drive retention but may limit market opportunities for AI startups.

• Anthropic's AI safety mission kept all 7 founders while OpenAI lost almost all but 1-2 founders—shared organizing principles create powerful team unity
• Pentagon rejected Anthropic's restrictions on mass surveillance and autonomous weapons, demanding ability to do anything 'legal'—government contracts require full control
• OpenAI immediately replaced Anthropic's $200M Pentagon contract after they walked away—competitors will fill gaps when you stick to principles
• Anthropic initially delayed Claude release before ChatGPT due to safety concerns—safety-first approach can cost first-mover advantage
• Pentagon threatened supply chain consequences for other vendors using Anthropic—losing government contracts can cascade beyond the initial deal
• AI defense contractors face the choice between safety principles and market opportunity—'making weapons safer' justification has limits

SaaS is minting millionaires again (here's how)

By Greg Isenberg

SaaS is experiencing a renaissance because building and distributing software has never been cheaper, with AI enabling solo founders to automate workflows in sub-niches and reach billion-dollar spending audiences. Isenberg's 30-step framework focuses on cash-flowing $100K-$1M monthly startups rather than VC-funded giants. This matters now because AI tools can handle everything from workflow mapping to content creation, making profitable SaaS accessible to individual builders.

• Target sub-niches within big markets (like FIRE movement within finance) rather than competing with VC-backed companies in massive markets to build cash-flowing $100K-$1M monthly businesses.
• Map your target customer's complete daily workflow end-to-end using AI tools like Claude or ChatGPT, then identify exactly where money changes hands to find software wedge opportunities.
• Quantify time savings in dollar terms - if someone makes $400/hour and you save them 100 hours yearly, that's $40K in value you can capture through your SaaS pricing.
• Spot repetitive mechanical steps in workflows (like checking leads across multiple channels) because these are prime targets for AI agents and automation features.
• Build media alongside your product by creating scroll-stopping content around your target workflow, using AI as your CMO to generate viral content ideas and scripts.
• Use AI tools like ideabrowser.com to discover profitable niches and automate content creation with tools that can generate ideas, scripts, and even AI videos indistinguishable from real ones.

Getting started with Slots

By Figma

Figma's new slots feature eliminates the dual overhead of rigid component variants and complex instance swapping methods that have plagued design systems. Slots let any nested frame become a container for custom content while maintaining auto-layout structure, giving designers composability without forcing detachment from the system. This matters now because design system maintenance costs are killing team velocity.

• Traditional design system approaches require either rigid boolean-based variants with hidden elements or complex instance swap methods with local component maintenance overhead
• Only nested frames within main components can become slots - rectangles, shapes, or parent frames won't work, creating specific architectural constraints
• Slot auto-layout settings from the component level automatically govern how custom content flows, requiring upfront workflow consideration during setup
• Default content in slots provides 90% use-case coverage while maintaining full customization flexibility through duplication and custom additions
• Three creation methods exist: right-click convert, Shift+Command shortcut, or properties panel binding to new slot properties
• Reset instance functionality lets designers return to default slot content after customization, providing a safety net for experimentation

How to Mail Merge Emails in Word (In 60 Seconds)

By Kevin Stratvert

Word's built-in mail merge feature can send personalized emails at scale without expensive automation tools. The complete workflow—Excel setup to automated sending through Outlook—takes under 60 seconds once configured. For cash-strapped startups drowning in manual outreach, this free alternative could replace $100+/month email marketing platforms.

• Use Excel sheets with names and email addresses as your data source for personalized email campaigns instead of complex CRM setups
• Word's Mailings tab provides a complete mail merge workflow that integrates directly with Outlook for automated sending
• Insert merge fields like First Name directly into your email template for dynamic personalization at scale
• Preview Results feature lets you validate your personalized emails before sending to avoid embarrassing mistakes
• HTML format option ensures your emails render properly across different email clients and look professional
