<!-- SC_OFF -->Just spotted Google’s latest move in the AI dev space — looks like they’re quietly testing a cloud-based environment that feels a lot like Cursor, but powered by Gemini models.
Curious if anyone here has tried it yet or benchmarked it against Cursor, Windsurf, or Codeium?

Builders vs. Mercenaries - two types of engineers I keep seeing. Does this make sense?
https://www.reddit.com/r/programming/comments/1p1wse8/builders_vs_mercenaries_two_types_of_engineers_i/

<!-- SC_OFF -->I have been thinking about a pattern I keep noticing in engineering teams, and I am curious if this resonates with anyone else or if I'm just making stuff up. Builders are all about the users and the problem domain. They see code as a tool to solve real problems. They'll ship something janky if it unblocks users. Ask them to optimize something that doesn't impact the user? They're not interested. Mercenaries are all about the craft. They care deeply about clean code, performance, architecture. They'll go deep on technical problems regardless of whether anyone actually needs it solved. The quality of the work matters to them independent of business impact. But I am not sure I'm framing this right. Few questions: Does this distinction actually exist or am I imagining patterns? Which type are you? Has it changed over your career? Would love to hear if anyone else sees this or if I'm way off base here. <!-- SC_ON --> submitted by /u/grandimam (https://www.reddit.com/user/grandimam)
