Focus on laying out all the pieces, such that there are no dead ends. There's very few ways to do that, afterwards you can quickly brute-force the rest. The winning move might be to not play, tbh. It was by far my least favorite level.

His method was fundamentally sound though. He realized that moonlight is reflected sunlight, and that if you observe the angle between the sun and the moon in the sky at exactly half moon, you can calculate the distance to the sun relative

Removing the GIL requires more locking/unlocking operations. For single-threaded program, it's a performance penalty on average: https://peps.python.org/pep-0703/#performance

Housing isn't bitcoin, it's possible to make more of it. And that's the point: Rent control often ends up disincentivizes construction, making it worse for tenants in the long run.

I only took a brief look, but from an API perspective, this seems identical to "normal" garbage collectors? In the sense that from the programmer's perspective, all the allocations live forever?

Looks like the arena is completely unsound if you mix types with different alignments? arena := NewSlabArena(8182, 1) // 8KB var b *byte = New[byte](arena) var i *int = New[int](arena) fmt.Printf("Pointer address:

A rising tide lifts all boats. Maybe "most valuable tech company in the world" would be a more convincing argument, since the tide receded shortly afterwards.

There just isn't enough memory bandwidth. Afaik dual-channel DDR5 still can't hit 100GB/s? Meanwhile the $270 RX 7600 has 288GB/s on-board memory.

You also have to know whether it's `cd cmd; go run main.go` or just `go run cmd/main.go`. And you have to know to set CGO_ENABLED=0 if you want to run it on Linux instead of MacOS.

I'm not sure how important the difference is in practice, offshore oil drilling sounds like something that can be easily disrupted during a war.

by sapiogram 3y ago
In terms of military strategy, your argument might make sense, but it's unsound from a purely economic perspective. Norway's solution is far better: Drill the oil now, export it, and invest the money abroad . From the perspective

Or alternatively, the vector was created with `Vec::with_capacity()` or `ExactSizeIterator::collect()`, and had the correct capacity all along.

by sapiogram 3y ago
It doesn't copy the elements if the source vector is already at max capacity, which you can often arrange for beforehand.
