After cloning https://github.com/cosmos/cosmos-sdk and trying to run the tests, it fails because the `go` binary couldn't be found in `$PATH`. ``` > dettrace -- make test contrib/devtools/Makefile:15: *** could not...

Okay, that issue is fixed now. Still getting this error: ``` # dettrace --network --env PATH --epoch '2019-09-23,15:00:00' -- make test /root/go/pkg/mod/github.com/bartekn/[email protected]/bip39.go:13:2: no Go files in /root/go/pkg/mod/golang.org/x/[email protected]/pbkdf2 make: *** [Makefile:101:...

Trying to simplify this, I tried to build a simple hello world Go program. `go build` hangs on it. When I kill it with `Ctrl-C`, it shows this error message:...

I'm not sure how helpful this is for debugging, but this sequence of syscalls are repeated over and over: https://gist.github.com/jasonwhite/ab44f37ae03f0b7bbf974b14269c0b65

@rrnewton I see. Although, it's the same error when running `go test` on a Hello World project under Dettrace, which I assume also relies on the Go compiler to find...

As far as I can tell, yes it does: https://github.com/cosmos/cosmos-sdk/blob/dc838ddd73d68439aa93742c9a7eb3c2bf7dbd8f/Makefile#L88-L144

I tried converting my `u64`s to `i64`s using: ```rust fn u64_to_i64(x: u64) -> i64 { // Simply flip the sign bit. This is equivalent to subtracting 2^63. (x ^ (i64::MIN...

I'll likely end up going with a quadtree instead. My use-case doesn't require the need to find the nearest neighbors. I only care about querying for which rectangles overlap with...

It has been used in production at various places for years now. It is an extremely stable service AFAIK. No telemetry is collected, so I don't have hard data to...
