Five engineers and their AI coding agents rebuilt the x.com web app in under six months. “Never rewrite from scratch” used to be gospel, but when writing code gets cheap, the hard part moves to the plan and the rollout. Here’s how that played out when I chose to build the Calendrz mobile apps natively, twice.
LinkedIn’s CISO says AI is shrinking the time between a flaw being found and it being exploited. What that means for patching, and how a small team like Calendrz keeps its dependencies current without having to think about it.
Wix Studio Two exports your site as React for Claude Code or Cursor, and Readwise opens your library to agents through MCP. Read the small print, though: both open the edges to your agent and keep the core. The lock-in hasn’t gone, it moved, and CTOs should ask what still calls home.
Ben Congdon splits software into interpolative (agents nail it from a few sentences) and novel (fighting uphill). Building Calendrz showed me exactly where that line runs, and why the bits you have to explain are the ones worth building.
Microsoft is offering buyouts to around 60,000 people as AI spending climbs. Why I think buyouts are a blunt instrument, and why the real prize for any company reshaping itself for AI is the speed of its decisions.
A founder rebuilt his whole platform alone with Claude Code, and his tests stayed green for weeks around a pigeon that never existed. When the agent writes the code and the tests, green proves less than you think: here’s what I’d check on Monday morning.
Agents are collapsing their tool catalogues into a single exec tool and writing code against your APIs. Having built an MCP server with 30+ tools for Calendrz, I think that makes your tool design more important, not less, and privacy has to live in the tools.
Europe and the US changed their clocks a week apart, and calendars everywhere got confused. Why storing a time zone id beats storing an offset, what it means for distributed teams, and why it matters even more now that agents book meetings.
Anthropic now tells companies what their Claude spend bought, and pools the budgets. Useful, but tokens are the new lines of code: measure outcomes, read the friction list, and remember who is marking the report card.
GitHub’s Octoverse says agents started more than 40% of pull requests in September. Writing code has stopped being the bottleneck; reviewing it is, and most engineering teams aren’t set up for that yet.
