@rsliveIndia How is the Ahmedabad - Dholera expressway quality?

SF has become the Kota for Indian founders. YC is IIT.

The clip that's making a lot of news from Express Adda with Ruchir Sharma Why foreign investors are not interested in India.

GPT-5.5 is off to an incredible start. Frontier AI leadership depends on two things working together: training more capable models, and serving them quickly, reliably, and efficiently at scale. GPT-5.5 was trained on the @Oracle Abilene supercomputer, part of our Stargate initiative and built on Oracle Cloud Infrastructure with @nvidia GB200 systems. A strong example of what deep partnership and ambitious execution can unlock.

you know what all of these "which is better" polls are silly use codex or claude code, whatever works best for you i am grateful we live in a time with such amazing tools, and grateful there is a choice

Redefining the Mumbai-Pune Commute What better way to celebrate May 1st than by witnessing a world-class feat of engineering? The Mumbai-Pune Missing Link is ready to redefine your travel. #MissingLink #MumbaiPune

Today we’re introducing a new Legal Agent in @Microsoft Word, built to support the precision and rigor legal work demands. Every clause matters. Every redline tells a story. That’s why this agent was built to follow the structured workflows lawyers use while keeping them fully in control. Early in my career, I asked for a computer on my desk because I believed technology could change how lawyers work. It did. Today, I believe this next generation of tools will do the same, grounded in trust and responsible use.

Claude Security is now in public beta for Claude Enterprise customers. Claude scans your codebase for vulnerabilities, validates each finding to cut false positives, and suggests patches you can review and approve.

Coding agents like Claude Code and others love Git worktrees. So, if you are using one or trying to build one, knowing about them is important, and here is what they are all about. A Git worktree lets you check out multiple branches of the same repository at the same time, each in its own directory. Not multiple clones. So essentially, one repo, many working directories, all sharing the same Git history and objects on disk. The problem they solve is context switching. Normally, if you are midway through work on one branch and need to jump to another, you stash, switch, do the work, switch back, and pop the stash. That context gets destroyed. With worktrees, you just open the other directory. Both branches stay live simultaneously. For coding agents, this is a 'godsend' :) It is how they run tasks in parallel without interfering with each other. An agent can be running tests on one branch in one worktree while writing new code in another. No waiting required, and things can move in parallel. Also, each worktree gets its own working tree and index, but they share the object store. So you are not actually duplicating gigabytes of history every time you spin one up. It is fast to create and cheap to maintain. You create one with `git worktree add ../feature-branch feature-branch`. That is it. The directory is ready, the branch is checked out, and your original workspace is untouched. Coding agents also get isolation guarantees. If one task crashes or corrupts its working tree, the others are unaffected. This makes Git worktrees a pretty natural fit for any system that needs to run concurrent, independent operations on the same codebase - aka coding agents :) Hope this helps.

Incredible stuff this - from both Openai - Cyber and Anthropic Mythos.... Application of super-intelligent LLMs towards cybersecurity critical for smooth and safe roll out.

we're starting rollout of GPT-5.5-Cyber, a frontier cybersecurity model, to critical cyber defenders in the next few days. we will work with the entire ecosystem and the government to figure out trusted access for cyber; we want to rapidly help secure companies/infrastructure.

iX1 sales more than X1! That's commendable conversion from the brand towards EV. #bmw

You can now ask Gemini to create Docs, Sheets, Slides, PDFs, and more directly in your chat. No more copying, pasting, or reformatting, just prompt and download. Available globally for all @GeminiApp users.

India doesn't need to lead the world in building the most advanced AI models. But it must lead in ensuring benefits of AI are widely shared. @rvenk and I have an op-ed in The @EconomicTimes economictimes.indiatimes.com/opinion/et-com…

Express Adda- Ruchir Sharma: my quick takeaways - US leads the AI race, powering its markets and economy - The world criticizes America, but capital continues to flow there - TSMC (Taiwan) thriving; Samsung will earn this year more than any US company except Nvidia - Americans largely insulated from war impact; Asia feels it more - China has cleverly built strong energy reserves - The world is burdened with excessive debt and deficits - India faces headwinds: limited AI scale, war spillovers, possible El Niño impact- yet India’s resilience remains a strength. Bottom line: India must aggressively attract FDI, build AI capability, and secure energy to stay relevant in the new global order.

@avgspacelover Ya, the new multipliers are insane.

@HarshitRathi_ Its 27 for 4.7 now

Github copilot needs to sort this out... 7.5x limits for frontier models like opus4.7 and gpt-5.5 is too much.

Agent Mode is here in Outlook! Copilot can now help run your inbox and calendar, triaging emails, rescheduling meetings, and helping you stay on top of what matters most.

WHAT HAVE WE JUST WITNESSED? 🤯 Sabastian Sawe has just become the first person in history to run a sub two-hour marathon in race conditions. Yomif Kejelcha was also under two hours for second!

Codex with gpt 5.5 is super good at instruction following and Agentic coding.

feels like a good time to seriously rethink how operating systems and user interfaces are designed (also the internet; there should be a protocol that is equally usable by people and agents)
