We changed the way we track Go threads in syscalls/cgo calls, which allowed us to remove one atomic store and one atomic compare-and-swap from the cgo call path. https://go.dev/cl/646198 and https://go.

How does this work when using a US credit card in the EU? I assume the merchant still pays the lower interchange fee, so are the banks just betting that customers won’t do a large proportion of spending abroad?

In addition to the DoS aspect mentioned in a sibling comment, the primary reason you would do this is to avoid constraining the implementation. If you want to change the design to improve performance, for example, being forced to match the

I think the closest analog to this is digital services getting worse rather than more expensive. For example, recently rather than increasing the price of Amazon Prime Video, the price has remained the same, but the product is worse (now ha

See https://news.ycombinator.com/item?id=34097179 . A comm is limited to 64 bytes, so I don't think it is possible to fit a long enough comm to match the full regexp.

by prattmic 4y ago
Neat! Your parser [1] almost has a similar issue because a comm could contain parenthesis, e.g., `foo) R 123 456`. But since a comm is limited to 64 bytes, I don't think it is possible to fit a fully matching string inside of the comm

Gerrit is pretty strongly opinionated, but it is not mailing-list based. Review notifications are sent via email, but otherwise everything needs to be done via the web UI (or other tool using the API).

I’m not familiar with Upsource, but what you describe sounds somewhat like the Gerrit review process. Each commit is reviewed individually, but sending multiple dependent commits for review is supported as well. It is technically possible f

While CPUID itself is far from elegant, I don't think ARM is fundamentally different. e.g., the ID_AA64ISAR1_EL1 register (ARM wins no naming awards here) indicates the presence of certain instructions. https://developer.arm

ARM has a weakly-ordered memory model, while x86 is much more strongly-ordered. See https://en.wikipedia.org/wiki/Memory_ordering#Runtime_memory... . So e.g., on x86 if you store to A then store to B, then if another co
