C is a weakly typed language. It’s statically typed, which is a different thing

For customers who repeatedly do this - put your prices up by 10%. Offer 10% discount for paying within net 15.

It’d be nice to have in stdlib, but it’s pretty trivial to write a generic wrapper for it

air source heat pumps, though they're improving won't do well in extreme cold; even if they can operate they'll still be running at much lower efficiency.

For temperatures significantly into negative territory a ground source heat pump would perform far better, where it can draw on a source of heat that will always be at least above freezing.

A hybrid system doesn't seem like a bad trade-off though..

It’s not uncommon. Google AIP spec requires it for example. I think the main driver for it is implicit idempotency.

That’s the point, surely

Similarly python in optimised mode with -O or -OO flags will disable asserts.

I see asserts as a less temporary version of print() based debugging. Sometimes very useful as a quick and dirty fix, but 9 times out of 10 you’re better off with some combination of a real debugger, unit tests, tracing/logging, and better typing or validation.

Great PR move, but surely better to invest in more basic security measures supported by their app (chain of trust, verified callers/messaging etc). Instead their app is primarily a react native sales tool. Part of the reason that o2 was so affected by scammers calling from south Asian call centres with “the latest offers” was because they used to do exactly this with their customers.

If there’s any scope for a user to inject JavaScript, then potentially this gives a vector of attack against other internal things (e.g admin.domain.com, operations.domain.com etc)

In the UK, dew point highs will peak above 22 degrees multiple times per year, so the safe temperature to cool to is something like 25 degrees.

Might provide some benefits on really hot days, but it’s still uncomfortably warm for working in.
