Installing rbx-2.0.0-dev with Ruby 1.9 support using rbenv can be a tad tricky. This is what I did to get up and running, you'll need another version of ruby already installed as well as rake.
The basic outline:
| L1 cache reference 0.5 ns | |
| Branch mispredict 5 ns | |
| L2 cache reference 7 ns 14x L1 cache | |
| Mutex lock/unlock 25 ns | |
| Main memory reference 100 ns 20x L2 cache, 200x L1 cache | |
| Compress 1K bytes with Zippy 3,000 ns | |
| Send 1K bytes over 1 Gbps network 10,000 ns 0.01 ms | |
| Read 1 MB sequentially from memory 250,000 ns 0.25 ms | |
| Round trip within same datacenter 500,000 ns 0.5 ms | |
| Read 1 MB sequentially from SSD 1,000,000 ns 1 ms 4X memory |
| Hash#structurally_equal? | |
| when compared with a single-level hash | |
| with the same keys | |
| should be true | |
| with different keys | |
| should be false | |
| with more keys | |
| should be false | |
| with less keys |
