I'm planning on using tanstack start in my next project. Seems to have had a lot of good press recently

It's the same as with any other new tech, start using it.

Use Claude Code, Figma MCP, Supabase MCP, Lovable, v0.dev.

Find where your interests overlap interesting tech, and who knows, you might be able to build a business from it

What's changed? Did you get older?

I wonder how much of it is down to the internet changing - similar to the eternal september, or overtourism.

Couchsurfing used to be a relatively niche thing which allowed it to work and thrive. The percentage of freeloaders or bad actors was low enough not to be a problem.

But now with more people being aware of it/its alternatives, the percentage of bad actors would increase too (and maybe not even proportionally to the number of good actors).

It probably also belonged to a certain period of time and a certain generation. The peak of couchsurfing coincided with millennials coming of age, and provided something that appealed to them at the time. Namely, cheap travel and interesting, random experiences to brag about.

That demographic is a lot older now, and the younger generation has other interests and expectations which couchsurfing likely does not appeal to.

The Internet changed the nature of tourism quite a bit as well. You have to remember most people used to use services like travel agents or tours to organize things for them. Anyone who went off the beaten path and was interested in experiencing another place by sleeping on a stranger’s couch was probably someone interesting.

Now everyone is used to using the internet to organize their travel and get the best deals on anything they can - and so websites like couchsurfing become a free booking.com alternative for people who have no interest in the human experience side of it.

Definitely. Just find a use case where you need the performance

Since ObjC(++) is a true superset of C (or C++), you can just write the performance-sensitive parts in C or C++ anyway. ObjC is only needed when talking to (most) macOS/iOS operating system APIs.

There is basically no real reason to write an iOS app in C. It won’t perform significantly better.

It really depends on how much ObjC features you use in the performance-sensitive parts of your code base.

If you build your entire code around the ObjC object model and not just the parts that talk to operating system APIs you might see a performance hit since ObjC method calls are simply more expensive than a direct C function call (especially since C function calls can often be inlined)., and even setting or getting an ObjC object property involves a method call.

But since ObjC is also a complete C there's really no point in using more ObjC OOP features than really needed (e.g. just for talking to iOS/macOS framework APIs).

Why do you focus on "performance" here?

Indeed, a programming language can't do wonders when the authors did not pay attention to algorithms and data structures.

Yeah. Many reasons your program might be too big or too slow still apply to C.

I'm sceptical that you can create entire apps. It might be good to get an MVP off the ground, but once you need to modify code it gets exponentially complicated because: 1) you're not familiar with the code AI wrote and 2) what it writes is generally more complicated.
